TY - JOUR T1 - Determination of polychlorinated biphenyl congeners and chlorinated pesticides in a fish tissue standard reference material. AN - 72983668; 12560966 AB - The concentrations of a wide range of polychlorinated biphenyl congeners (PCBs) and chlorinated pesticides in a fish tissue Standard Reference Material (SRM) have been determined using multiple methods of analysis. This material, SRM 1946, Lake Superior Fish Tissue, was recently issued by the National Institute of Standards and Technology (NIST) and complements a suite of marine environmental natural-matrix SRMs that are currently available from NIST for the determination of organic contaminants such as aliphatic hydrocarbons, polycyclic aromatic hydrocarbons (PAHs), PCBs, and chlorinated pesticides. SRM 1946 is a fresh tissue homogenate (frozen) prepared from filleted adult lake trout (Salvelinus namaycush namaycush) collected from the Apostle Islands region of Lake Superior. SRM 1946 has certified and reference concentrations for PCB congeners, including the three non- ortho PCB congeners, and chlorinated pesticides. Certified concentrations are available for 30 PCB congeners and 15 chlorinated pesticides. Reference concentrations are available for 12 PCB congeners and 2 chlorinated pesticides. In addition, SRM 1946 is characterized for additional chemical constituents and properties: fatty acids, extractable fat, methylmercury, total mercury, selected trace elements, proximates, and caloric content. The characterization of chlorinated compounds is described in this paper with an emphasis on the approach used for the certification of the concentrations of PCB congeners and chlorinated pesticides. The PCB congener and chlorinated pesticide data are also compared to concentrations in other marine natural-matrix reference materials available from NIST (fish oil, mussel tissue, whale blubber, and a second fresh frozen fish tissue homogenate prepared from filleted adult lake trout collected from Lake Michigan) and from other organizations such as the National Research Council Canada (ground whole carp), the International Atomic Energy Agency (fish homogenate), and the European Commission Joint Research Centre [fish oils (cod and mackerel) and mussel tissue].

Despite obvious connections between habitat and threatened or endangered species, conservationists have been hard pressed explicitly to link abundance or population health with habitat attributes. Given that habitat relationships with species are often characterized at a spatial scale that does not account for the functional relationships between habitat and populations, it is not surprising that the habitat-population conundrum persists. In order to explore the influence of spatial scale on the apparent relationship between habitat and populations, the authors examined the relationship between GIS-based habitat data and spring/summer chinook salmon (Oncorhynchus tshawytscha) redd (spawning nests built by females) densities in the Salmon River basin, Idaho, at two very different spatial scales: stream reach and watershed. Redd density was strongly correlated with climate, geology, wetlands and terrain. However, the stream-reach scale models provided poor predictive power compared with the watershed scale models. Based on these results, it is concluded that the perception of which habitat attributes were important was clearly a function of the scale of observation, and that restoration efforts should focus on conditions at the watershed or landscape scale when attempting to do local or reach scale restoration projects JF - Animal conservation AU - Feist, B E AU - Steel, E A AU - Pess, G R AU - Bilby, R E AD - Environmental Conservation Division - Watershed Program, National Marine Fisheries Service, 2725 Montlake Boulevard East, Seattle, WA 98112-2097 USA, Blake.Feist@noaa.gov Y1 - 2003 PY - 2003 DA - 2003 SP - 271 EP - 282 VL - 6 IS - 3 SN - 1367-9430, 1367-9430 KW - Chinook salmon KW - ASFA 3: Aquatic Pollution & Environmental Quality KW - Redds KW - USA, Idaho, Salmon R.

Premolt crabs were collected in situ by scuba divers and held in the laboratory until molting occurred ( less than or equal to 33 d). An interannual difference in growth was not found, but growth was significantly greater (2.3% to 6.2%) than that observed for Kodiak Island area crabs during the 1970s. Current management of Tanner crabs throughout Alaska is based on growth estimated for Kodiak Island crabs in the 1970s. A significant change in allometric growth occurred at 96.5 mm carapace width. Growth was reduced for crabs held in the laboratory >13 d, crabs missing three or more premolt limbs, and crabs missing two or more postmolt limbs. Crabs attained large-claw status over a wide size range (approximately 125.0 to 178.9 mm postmolt carapace width) and among large-clawed crabs a percent increase in chela height was not associated with a percent decrease in growth. Growth data indicated that the majority (53% to 70%) of Tanner crabs harvested in the Southeast Alaska commercial fishery during most years were newly recruited to the fishery.

These offshore structures function as artificial reefs attracting a wide variety of marine life, including the commercially and recreationally important red snapper. A multi-year study estimated the mortality of red snapper resulting from the explosive removal of nine platforms at water depths of 14-36 m. Estimated mortality of red snapper due to underwater explosives averaged 515 per platform. Using this value, we estimated the total annual mortality of red snapper resulting from all explosive structure removals in the U.S. Gulf of Mexico. The recent stock assessment for red snapper was subsequently recalculated, including this additional source of mortality. Results showed no discernible difference between the two stock assessments, indicating that direct mortality resulting from explosive structure removals was minor compared with other sources of mortality.

This study compared the NOHRSC snow cover maps with new automated snow cover maps produced by the National Environmental Satellite, Data, and Information Service (NESDIS) and the snow cover maps created from the Moderate Resolution Imaging Spectroradiometer (MODIS) imagery. The purpose of this paper is to demonstrate and account for the differences that occur between the three different snow cover mapping techniques. Because each of these snow cover products uses data from different sensors at different resolutions, the data were degraded to the coarsest relevant resolution. In both comparisons, forest canopy density was examined as a possible explanatory factor to account for those differences. NOHRSC snow cover maps were compared with NESDIS snow cover maps for 32 different dates from November 2000 to February 2001. NOHRSC snow cover maps were also compared with MODIS snow cover maps in the Pacific Northwest and the Great Plains for 18 days and 21 days, respectively, between March and June 2001. In the first comparison, where the NOHRSC product ( similar to 1 km) was degraded to match the resolution of the NESDIS data ( similar to 5 km), the two products showed an average agreement of 96%. Forest canopy density data provided only weak explanation for the differences between the NOHRSC and the NESDIS snow cover maps. In the second comparison, where the MODIS product ( similar to 500 m) was degraded to match the resolution of the NOHRSC product for two sample areas, the agreement was 94% in the study area in the Pacific Northwest, and 95% in the study area in the Great Plains.

AN - 36420594; 9860 AB - PURPOSE: The issuance of incidental take permits with respect to 50-year anadromous fish agreements and habitat conservation plans (HCPs) within two public utility districts located in Chelan and Douglas counties, Washington is proposed. The HCPs were developed to protect five species of Columbia River steelhead trout and salmon, two of which are currently listed as endangered under the Endangered Species Act of 1973, The HCPs' fish protection measures also satisfy the utilities regulatory obligations under the Federal Power Act Fish and Wildlife Coordination Act, Pacific Northwest Electric Power and Planning Conservation Act, and the Regulatory Code of Washington (Title 77). The permit agreements would set a "no net impact" standard for salmon and steelhead protection at three hydropower projects (Wells, Rocky Roach, and Rock Island) operated by the utilities. The hydropower projects, which are part of an 11-dam system on the mainstem Columbia River, are federally operated although the local utilities operate five of the projects in the Mid-Columbia River segment, including the projects under consideration. The project boundaries include the forebay, from the dam to approximately 500 feet upstream; tailrace, from the dam to approximately 1,000 feet downstream; and the reservoir associated with each dam. The Rock Island reservoir extends approximately 20 miles upstream of the dam to the Rocky Reach tailrace; the Rocky Reach reservoir extends approximately 41 miles upstream of the dam to the Wells tailrace; and the Wells reservoir extends approximately 30 miles upstream of the dam to the Chief Joseph Dan tailrace. Considering all components of the three projects, the entire project area extends from the tailrace of the Rock Island Dam upstream to the tailrace off the Chief Joseph Dam. Project effects, however, may continue downstream through the Hanford reach to the McNary Dam, inclusively defined as the action area. Three alternatives, including a No Action Alternative (Alternative 1), are considered in this final EIS. Alternative 2 would involve issuance of the permit for the two endangered species as well as issuance of a biological opinion. Alternative 3, which is the proposed action, would involve issuance of an incidental take permit only. Under Alternative 3, three HCPs representing the Wells, Rocky Roach, and Rock Island hydroelectric projects would be approved and in effect over a 50-year permit term. Specific measures to assist in fish passage would include fishways, fish ladders, fish bypasses, modified turbine operations, predator removal, fish hatcheries, fishery monitoring research programs, and spill arrangements. POSITIVE IMPACTS: The permits would provide the utilities with some degree of certainty for long-term operation of these facilities. Plan coverage of the three species not listed as endangered should help prevent the need to list these species in the future. Incremental water quality improvements would be expected in downstream areas and in tributaries. NEGATIVE IMPACTS: Reservoir drawdown would decrease the extent of the reservoirs and increase turbidity in the impounded waters, affecting the lake fishery and associated resources. Drawdown would also increase turbidity downstream. Gull abundance and the abundance of other waterfowl and species dependent on reservoir habitat could decline. Habitat enhancement programs could alter floodplains, result in short-term restrictions on recreational access, and affect cultural resources.

Rainfall over land AN - 18722282; 5606866 AB - This study has investigated the error associated with the estimation of instantaneous areal rain rate over land by the NOAA/NESDIS Office of Research and Application's Special Sensor Microwave/Imager (SSM/I) algorithm. By comparing with ground-based rain observations from the Oklahoma Mesonet rain gage network, the error inherent in the SSM/I-based areal rain estimate is quantified. Since the ground-based gauges use point measurements to estimate areal rain, the gauges do not make a perfect estimate and contain an associated error. A formulation has been developed by which the difference between the SSM/I- and Mesonet-based estimates is divided into two parts: one due to the error in the Mesonet and the other due to the error in the SSM/I. A separate formulation has also been developed by which the error in Mesonet-based rain measurement is quantified according to the gage density and the statistics of rain (variance and spatial correlation). A nine-month data set of 15-min rain accumulation for over 100 gages from the Mesonet has been used to obtain the rain statistics and to compare with the SSM/I estimate over various spatial scales. Results show that the error for the instantaneous SSM/I rain rate over 0.5, 1.0, and 2.5-degree boxes are approximately 150%, 100%, and 70% of the mean areal rain rate, respectively.

AN - 72742222; 12465979 AB - The interaction of small phospholipid vesicles with well-characterized surfaces has been studied to assess the effect of the surface free energy of the underlying monolayer on the formation of phospholipid/alkanethiol hybrid bilayer membranes (HBMs). The surface free energy was changed in a systematic manner using single-component alkanethiol monolayers and monolayers of binary mixtures of thiols. The binary surfaces were prepared on gold by self-assembly from binary solutions of the thiols HS-(CH(2))(n)()-X (n = 11, X = CH(3) or OH) in THF. Surface plasmon resonance (SPR), electrical capacitance, and atomic force microscopy (AFM) measurements were used to characterize the interaction of palmitoyl,oleoyl-phosphatidylcholine (POPC) vesicles with the surfaces. For all surfaces examined, it appears that the polar part of surface energy influences the nature of the POPC assembly that associates with the surface. Comparison of optical, capacitance, and AFM data suggests that vesicles can remain intact or partially intact even at surfaces with a contact angle with water of close to 100 degrees. In addition, comparison of the alkanethiols of different chain lengths and the fluorinated compound HS-(CH(2))(2)-(CF(2))(8)-CF(3) that characterize with a low value of the polar part of the surface energy suggests that the quality of the underlying monolayer in terms of number of defects has a significant influence on the packing density of the resulting HBM layer.

[Part 1 of 2] T2 - ISSUANCE OF A MULTIPLE SPECIES PERMIT FOR INCIDENTAL TAKE AND IMPLEMENTATION OF THE J.L. STOREDAHL AND SONS, INC. DAYBREAK MINE EXPANSION AND HABITAT ENHANCEMENT HABITAT CONSERVATION PLAN, CLARK COUNTY, WASHINGTON. AN - 36389650; 9842-020498_0001 AB - PURPOSE: The issuance of a 25-year multiple-species permit for the incidental take of nine federally protected, candidate, and proposed salmonids and terrestrial species at the expanded Daybreak Mine in Clark County, Washington is proposed. The 300-acre project site is located in a relatively flat alluvial valley on the north bank of the East Fork River, between River Mile 7.2 and River Mile 9.0. The applicants, Storedahl and Sons, Inc. and Storedahl Properties LLP, would expand mining and reclamation activities and the processing of sand and aggregate at the site. Permit approval would require the implementation of a habitat conservation plan (HCP) at the mine site and within adjacent properties owned by the applicants. Four alternatives, including two no action alternatives, are considered in this draft EIS. The No Action alternatives would involve either A-1) continued processing of imported mineral resources, but no additional mining on the project site, which would be partitioned into rural residential or agricultural tracts, or A-2) expansion of mining and processing at the site followed by partitioning of the site into rural residential tracts. Action alternatives would involve either B) expansion of mining and processing at the site, combined with reclamation activities under the HCP, or C) expansion of mining at the site, combined with reclamation of the property according to an earlier draft HCP. Alternative B, the preferred alternative, would result in expansion of mining and reclamation over an additional 101 acres and backfilling of approximately 26 acres of existing ponds. Mining would take place under a comprehensive program that would encompass 18 conservation measures, including a $1.0 million endowment to facilitate site management and preservation of the preserved area in perpetuity. The habitat created would be comprised of a mosaic of open water, emergent wetlands, and valley bottom forest created from gravel mining and the natural features of the project site. Upon completion of the project, a conservation easement prohibiting future uses that would conflict with fish and wildlife habitat values would be obtained for the property, together with the fee simple title conveyed to one or more public or nonprofit conservation organizations. The latter provisions would ultimately make the property available for inclusion in Clark County's ongoing lower East Fork River greenbelt. The 18 conservation would address into four issues, namely, water quality, water quantity, channel avulsion, and species and habitat conservation. POSITIVE IMPACTS: Mining and processing of sand and aggregate would provide materials for use by the construction industry throughout the region. The HCP would increase the extent of forested upland, emergent wetlands, and open water ponds. Some restoration and enhancement measures would occur within the 100-year floodplain. Fish and water quality enhancements would exceed those required by local planning requirements. NEGATIVE IMPACTS: Topography and soil composition at the site would be altered significantly. Traffic at four intersections along transportation routes in the vicinity of the site would continue to be affected by congestion due to the number of trucks necessary to haul sand and gravel from the site. Mining activities and rural and agricultural developments would be visible from adjacent at-grade properties. Recreational opportunities could be curtailed by private owners of the site subsequent to the conclusion of the project. Noise levels from mining and processing activities would increase somewhat.

Changes in freshwater inflow are expected to affect salinity patterns in the bay, so the effect of salinity and temperature on the growth, survival, and subsequent recruitment and harvest of this ecologically and economically important species was examined with laboratory experiments and a simulation model. Experiments were conducted to determine the response of juvenile growth and survival to temperature (15 degree C to 33 degree C) and salinity (2ppt to 55ppt), and results were used to refine an existing model. Results of these experiments indicated that juvenile pink shrimp have a broad salinity tolerance range at their optimal temperature, but the salinity tolerance range narrows with distance from the optimal temperature range, 20-30 degree C. Acclimation improved survival at extreme high salinity (55ppt), but not at extremely low salinity (i.e., 5ppt, 10ppt). Growth rate increases with temperature until tolerance is exceeded beyond about 35 degree C. Growth is optimal in the mid-range of salinity (30ppt) and decreases as salinity increases or decreases. Potential recruitment and harvests from regions of Florida bay were simulated based on local observed daily temperature and salinity. The simulations predict that potential harvests might differ among years, seasons, and regions of the bay solely on the basis of observed temperature and salinity. Regional differences in other characteristics, such as seagrass cover and tidal transport, may magnify regional differences in potential harvests. The model predicts higher catch rates in the September-December fishery, originating from the April and July settlement cohorts, than in the January-June fishery, originating from the October and January settlement cohorts. The observed density of juveniles in western Florida Bay during the same years simulated by the model was greater in the fall than the spring, supporting modeling results. The observed catch rate in the fishery, a rough index of abundance, was higher in the January-June fishery than the July-December fishery in most of the biological years from 1989-1990 through 1997-1998, contrary to modeling results and observed juvenile density in western Florida Bay.

Modifications include a revised preformed alkalinity term, a correction for denitrification, and an evaluation of the disequilibrium terms using an optimum multiparameter analysis. The total anthropogenic CO (super 2) inventory over an area from 120 degrees E to 70 degrees W and 70 degrees S to 65 degrees N (excluding the South China Sea, the Yellow Sea, the Japan/East Sea, and the Sea of Okhotsk) was 44.5+ or -5 Pg C in 1994. The deepest penetration of anthropogenic CO (super 2) is found at about 50 degrees S. The shallowest penetration is found just north of the equator. Very shallow anthropogenic CO (super 2) penetration is also generally observed in the high-latitude Southern Ocean. (modif. j. abstr.)

Efforts to manage urban streams traditionally take an engineering approach focused on stormwater runoff, physical channel condition, and chemical water quality. Our objective was to use the biology of streams-measured with the multimetric benthic index of biological integrity ( B-IBI) based on benthic macroinvertebrates-to assess stream health. From 1997 to 1999, we sampled invertebrates at 45 sites in second- and third-order streams in the Puget Sound lowlands of Washington State. Land cover upstream of each site was characterized by analysis of a 1998 satellite image. We evaluated associations between five land cover categories and biological condition across three spatial scales. The relationships between B-IBI (and its component metrics) and stream substrate and hydrologic features were also analyzed at a subset of sites. Across all study sites, B-IBI declined as the percentage of urban land cover increased (r 31). Most metrics were better predicted by sub-basin rather than local-scale urbanization. Within individual basins, however, local land-cover urbanization and B-IBI were strongly correlated (r = -0.91, p 31). La mayoria de los componentes metricos fueron predichos mejor por las sub-cuencas que por la escala de urbanizacion local. Sin embargo, dentro de las cuencas individuales, la cobertura del suelo por urbanizacion y B-IBI estuvieron fuertemente correlacionadas (r = -0.91, p < 0.001, n = 9). La condicion biologica en los sitios estuvo tambien relacionada con las medidas de alteracion hidrologica y el substrato del arroyo. La biota acuatica es sensible a una variedad de efectos urbanos-expresados tanto a escalas espaciales grandes como pequenas. Las herramientas de evaluacion biologica tales como B-IBI pueden identificar areas de excelente condicion biologica para la conservacion y conducir el diseno y evaluacion de los esfuerzos para restaurar la biota de arroyos degradados.

The high concentrations are of concern because a growing body of experimental evidence links PCBs to deleterious effects on reproduction, endocrine homeostasis, and immune system function. Much of the recent research has focused on determining the exposure of marine mammal populations to PCBs, but very little effort has been devoted to the actual risk assessments that are needed to determine the expected impacts of the documented exposures. We describe a novel risk assessment approach that integrates measured tissue concentrations of PCBs with a surrogate dose-response relationship and leads to predictions of health risks for marine mammals as well as to the uncertainties associated with these predictions. Specifically, we use PCB tissue residue data from three populations of bottlenose dolphins (Tursiops truncatus), study the feasibility of published dose-response data from a surrogate species, and combine this information to estimate the risk of detrimental reproductive effects in female dolphins. Our risk analyses for dolphin populations near Beaufort (NC, USA), Sarasota (FL, USA), and Matagorda Bay (TX, USA) indicate a high likelihood that reproductive success, primarily in primiparous females, is being severely impaired by chronic exposure to PCBs. Excess risk of reproductive failure, measured in terms of stillbirth or neonatal mortality, for primiparous females was estimated as 60% (Beaufort), 79% (Sarasota), and 78% (Matagorda Bay). Females of higher parity, which have previously off-loaded a majority of their PCB burden, exhibit a much lower risk.

This action created the first estuarine, largest and oldest no-take reserves in North America. Areas surrounding the no-fishing areas are important for recreational fishing, including catch-and-release sport fishing (Cocking 1999). Johnson et al. (1999) compared fish populations in three no-fishing areas with three adjacent fished areas at Cape Canaveral between 1986 and 1990. They documented significantly higher average fish biodiversity and catch per unit effort (CPUE) for several economically important species in no-fishing zones than in surrounding fished areas in the Mosquito Lagoon, South Banana River, and Indian River Lagoon. Fishes captured from no-take areas also tended to be larger and older than those from fished areas, and many were in breeding condition. Tagging showed that some fishes moved from protected areas to surrounding fished areas. Johnson et al. (1999) did not, however, investigate impacts of the no-take reserves on nearby fisheries. Using available published International Game fish Association (IGFA) world records from 1955 through 1997 (e.g., IGFA 1997), two hypotheses were tested: the first, that the number of world records around Cape Canaveral was no different than those from other areas around Florida (spatial hypothesis) and the second, that the proportion of recreational world records near MIWR has not changed since areas were closed to fishing (temporal hypothesis).

The analysis uses a simple model of patch dynamics for seral stages in an idealized landscape; each seral stage is assumed to support a specialist biota. The landscape as a whole is characterized by a mean patch birth rate, mean patch size, and mean lifetime for each patch type. Stochasticity takes three forms: (1) patch stochasticity is randomness in the birth times and sizes of individual patches, (2) landscape stochasticity is variation in the annual means of birth rate and size, and (3) turnover mode is whether a patch is eliminated by disturbance or by successional change. Analytical and numerical analyses of the model suggest that landscape stochasticity is the most important agent. Landscape stochasticity increases the extinction risk to species by increasing the risk that the habitat will fluctuate to zero, by reducing the mean abundance of species, and by increasing the variance in species abundance. The highest risk was found to occur in species that inhabit patches with short lifetimes. The results of this general model suggest an important mechanism by which climate change threatens biodiversity: an increase in the frequency of extreme climate events will probably cause pulses of disturbance during some time periods; these in turn would cause wider fluctuations in annual disturbance rates and thus increase the overall level of landscape stochasticity. However, the model also suggests that humans can manipulate landscape stochasticity to reduce risk. In particular, if managed disturbances were more evenly distributed in time, attrition of the regional biota might be prevented. Other work on the connection between patch dynamics and extinction risk assumes the absence of landscape stochasticity and thus overlooks an important component of risk to biodiversity.

Variability in beta across ecosystems and climates was analyzed by quantifying general climatic and surface characteristics that control flux partitioning. The climatic control on beta was quantified using the climatological resistance (R sub(i)), which is proportional to the ratio of vapor pressure deficit (difference between saturation vapor pressure and atmospheric vapor pressure) to net radiation (large values of R sub(i) decrease beta ). The control of flux partitioning by the vegetation and underlying surface was quantified by computing the surface resistance to water vapor transport (R sub(c), with large values tending to increase beta ). There was a considerable range in flux partitioning characteristics (R sub(c), R sub(i) and beta ) among sites, but it was possible to define some general differences between vegetation types and climates. Deciduous forest sites and the agricultural site had the lowest values of R sub(c) and beta (0.25-0.50). Coniferous forests typically had a larger R sub(c) and higher beta (typically between 0.50 and 1.00 but also much larger). However, there was notable variability in R sub(c) and R sub(i) between coniferous site years, most notably differences between oceanic and continental climates and sites with a distinct dry summer season (Mediterranean climate). Sites with Mediterranean climates generally had the highest net radiation, R sub(c), R sub(i), and beta . There was considerable variability in beta between grassland site years, primarily the result of interannual differences in soil water content and R sub(c).

This is a key advantage over many flame retardants, which reduce flammability but also reduce the mechanical properties of the polymer. In our efforts to further understand the mechanism of flame retardancy with polymer-clay nanocomposites, we investigated the effect of the clay, the loading level and polymer melt viscosity on the flammability of polystyrene-clay nanocomposites. The nanoscale dispersion of the clay in the polymer was analysed by wide-angle X-ray diffraction (XRD) and transmission electron microscopy (TEM). Cone calorimetry and gasification studies were used to evaluate the flammability of these nanocomposites. There were major reductions in peak heat release rates (HRRs), and increased carbonaceous char formation, for these nanocomposites. It was determined that while the viscosity of the PS nanocomposite played a role in lowering the peak HRR, the clay loading level had the largest effect on peak HRR. Finally, it was found that clay catalysed carbonaceous char formation, and the reinforcement of the char by the clay was responsible for the lowered flammability of these nanocomposites.

The purpose was to study the diving behaviour and habitat use of free-ranging pilot whales in the northeast Atlantic. Summarised data on the diving behaviour of the whales were collected for up to 129 6-hour periods. The maximum depth of dives was 828 m and the mean number of dives below 12 m was 12.2/hour (SD = 8.2). On average, the whales spent 60% of their time above 7 m depth. All three whales had significantly longer surface times when they were outside the continental shelf than when they were on the shelf. The mean vertical speeds ranged from 0.9 m/second for dives to 150 m to 2.3 m/second for dives to 600 m. No dives below 12 m lasted longer than 18 minutes, and more than 60% of dives lasted less than three minutes. The mean number of dives that lasted less than one minute was significantly higher in offshore areas than on the continental slope for all three whales. Compared to other odontocetes of similar size, long-finned pilot whales apparently either have a lower dive capacity or utilise a niche in the water column that requires less diving activity.

The structures of the hypothetical proteins are being used to guide further studies and narrow the field of such studies for ultimately determining protein function. An outline of the structural genomics methodological approach is provided along with summaries of a number of completed and in progress crystallographic and NMR structure determinations. With more than twenty-five structures determined at this point and with many more in various stages of completion, the results are encouraging in that some level of functional understanding can be deduced from experimentally solved structures. In addition to aiding in functional assignment, this effort is identifying a number of possible new targets for drug development.

Nekton predators, including many juvenile fishery species, aggregate near this marsh edge, and benthic infaunal populations are a primary source of prey for many of these predators. We examined the fine-scale (1-10 m) distributions of benthic infauna in relation to the edge of a Texas, USA salt marsh. Every six weeks for nearly a year, we sampled marsh sediments at five locations: on nonvegetated bottom 1 m from the marsh edge and on the vegetated marsh surface at 1, 3, 5, and 10 m from the edge. Surface-dwelling annelid worms and peracarid crustaceans were most abundant in low-elevation sediments near the marsh edge for most sampling periods. Because the marsh slope varied within the study area, we could distinguish between correlative relationships with elevation and distance from the marsh edge. Distributions of common surface-dwelling species were often unrelated to elevation but almost always negatively related to distance from the marsh edge. Abundances of near-surface direct deposit feeders and omnivores were related to both distance from edge and elevation. In contrast to surface dwellers, densities of abundant subsurface deposit feeders (mainly oligochaetes) were frequently greatest in sediments located away from the marsh edge. Surface and near-surface dwelling infauna are an important prey resource for nekton, including many juvenile fishery species that concentrate near the marsh edge. Populations of these infaunal prey fluctuated seasonally, with the greatest densities occurring during winter and early spring when predator abundances are generally low. Infaunal densities decreased dramatically near the marsh edge from the late spring through early fall, and this decrease coincides with historically high seasonal densities of nekton predators. Our data suggest that there is a strong trophic link between infauna and nekton near the marsh edge and that this relationship contributes to the high fishery productivity derived from Gulf Coast marshes.

We tested the hypothesis that hatchery-reared steelhead salmon ( Oncorhynchus mykiss) released into the Snake River Basin negatively affect the survival of wild Snake River steelhead and chinook ( O. tshawytscha) salmon. Because climatic conditions can influence salmon survival, we included an index of the El Nino-Southern Oscillation ( ENSO) as a covariate in our analyses. Based on time series of hatchery releases and rates of smolt-to-adult survival, we demonstrate that the survival of wild chinook salmon is negatively associated with hatchery releases of steelhead. The state of the ( ENSO) did not affect the strength of this relationship. We observed no relationship between survival of wild steelhead and steelhead hatchery releases. Our results suggest that industrial-scale production of hatchery fish may hinder the recovery of some threatened salmonids and that the potential interspecific impact of hatcheries must be considered as agencies begin the process of hatchery reform.Original Abstract: Por mas de 120 anos, las granjas han liberado numeros enormes de salmones del Pacifico para compensar las numerosas agresiones humanos a sus poblaciones, sin embargo, los impactos ecologicos de este esfuerzo masivo son poco entendidos. Evaluamos la hipotesis de que la trucha cabeza de acero ( Oncorhynchus mykiss) criada en granjas y liberada en la cuenca del Rio Snake afecta negativamente la supervivencia de truchas cabeza de acero y salmones chinook ( O. tshawytscha) silvestres. Puesto que las condiciones climaticas pueden influir sobre la supervivencia del salmon, incluimos un indice de la Oscilacion del Nino del Sur como covariable del analisis. En base a series de tiempo de las liberaciones de las granjas y las tasas de supervivencia hasta adulto de peces migrantes al mar, demostramos que la supervivencia del salmon chinook silvestre esta negativamente correlacionada con las liberaciones de truchas cabeza de acero de las granjas. El estado de la Oscilacion del Nino del Sur no afecto el grado de correlacion. No observamos relacion alguna entre la supervivencia de las truchas silvestres y las liberaciones de las granjas. Nuestros resultados sugieren que la produccion a escala industrial de peces de granja puede obstaculizar la recuperacion de algunos salmonidos amenazados y que el impacto interespecifico potencial de las granjas deberia ser considerado en cuanto las agencias inicien el proceso de reforma de las granjas.

We conducted surveys in late winter and early summer each year using an underway sampler and a bongo net towed vertically at fixed stations. A neuston sampler was added in 1999. We used bongo net data, thought to give the best estimates of ichthyoplankton abundance, as the primary data to identify distributions. Cluster analyses showed that season was the major environmental signal in the ichthyoplankton data, with clear indications of the El Nino/Southern Oscillation events of 1998 and 1999, and more tenuous suggestions of adult habitat preferences and faunal affinities. Between- and within-site adult habitat preferences were apparent in analyses of individual taxa. Eggs and larvae of rocky-bottom and kelp forest taxa were most abundant at the islands where those habitats are available, and the eggs and larvae of soft-bottom taxa were more abundant at the Big Sycamore Canyon site, where that habitat predominates. It appears that no significant production of planktonic fish eggs and larvae occurred in the vicinity of Vandenberg Ecological Reserve. At the Big Sycamore Canyon site, eggs of a few taxa clearly are produced from the reserve but probably not in higher numbers than from adjacent nonreserve areas.

Marine Sanctuary; Marine ER - TY - JOUR T1 - The state of the California Current, 2001-2002: Will the California Current system keep its cool, or is El Nino looming? AN - 18039988; 5742728 AB - This report summarizes physical and biological conditions in the California Current System (CCS), from Oregon to Baja California, in 2001 and 2002. The principal sources of the observations described here are the CalCOFI (California Cooperative Oceanic Fisheries Investigations), IMECOCAL (Investigaciones Mexicanas de la Corriente de California), and U.S. GLOBECLTOP (Global Ecosystems Long-term Observation Program) programs. Large-scale atmospheric and oceanic conditions in the Pacific point to a fourth consecutive La Nina-like year. This has contributed to generally stronger than normal upwelling and uncharacteristically cool waters in much of the CCS, a pattern that has persisted since late 1998. Biological productivity has been generally higher as well, particularly off Oregon. Within the observed interannual fluctuations of recent years, these conditions suggest a generally elevated production off California and Oregon, but cool conditions have led to lower than normal zooplankton biomass off Baja California. Although the tropical Pacific has exhibited some indications of a developing El Nino, it is not likely to impact the CCS during the productive upwelling season of 2002. These observations are continuing evidence that a regime shift may have occurred in 1998, resulting in substantial change in ecosystem structure in the CCS. Continued monitoring and analysis of the state of the CCS in this context is needed. We outline a plan for an integrated monitoring program for the entire region, through the creation of ACCEO (Alliance for California Current Ecosystem Observation).

We used side scan sonar and an occupied submersible to collect baseline information on species-habitat relationships, density, and species and size composition of fish inside and outside BCER. Forty-three dives were made in the fall of 1997 and 1998, at depths of 20-250 m. From 142 video transects, we identified over 70,000 fish from 82 taxa, including 36 species of rockfish. About 93% of the 25,159 fish inside BCER were rockfishes representing at least 20 species. Young-of-the-year rockfishes dominated rock outcrops in 20-90 m depth inside and outside BCER. Four distinct fish assemblages were associated with (1) fine, smooth sediment in deep water; (2) bedrock with uneven surface in deep water; (3) sand waves and shell hash in shallow water; and (4) boulders and organic habitats on rock in shallow water. There were no significant differences in fish density among locations (inside and outside BCER) and depths or between years. Density was significantly higher in high-relief rock habitat than in low-relief soft and mixed sediments, regardless of location. There were no consistent patterns of larger fish inside compared to outside the protected area. We recommend development of a monitoring program to continue these surveys after increased time of protection and with increased assessment effort in the appropriate habitats of economically valuable species. In addition, extending the boundaries of BCER seaward would protect habitats and fish in water depths greater than 100 m.

The coastal ocean is widely used for commercial fishing, and is extensively developed for recreational use. Monitoring the health of the coastal zone is possible with satellite remote sensing systems. Current applications are adapted from systems designed for the open ocean. The numerous applications in the coastal ocean require greater refinement. These include river plumes and outfalls, tidal plumes, algal blooms, aquaculture, water quality, bathymetry, maritime operations, fisheries, oceanography, tidal marshes, and geomorphology. Typical satellite instruments are characterized by satellite, sensor, swath, pixel size, type, and web site.

The clones were partially characterized and 4 were selected for complete analysis. Sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE), 2-dimensional PAGE, Western blotting, and DNA sequencing were used to analyze expressed antigenic proteins and encoded genes. Sequence analysis identified 4 putative open reading frames (ORFs) in the insert of Clone 4d6, which corresponded to antigenic acidic proteins of 55, 20 and 18 kDa expressed by both the clone and E. ictaluri cells. The predicted gene products of these ORFs were similar to several products of the imp locus of Rhizobium leguminosarum bv. trifolii. The imp locus of R. leguminosarum contains 14 genes that encode proteins involved in a putative temperature-dependent protein secretion system. In addition there was significant amino acid identity for a variety of hypothetical proteins from R. solanacearum, Ps. aeruginosa, A. tumefaciens, Y. pestis, and Salmonella typhimurium. Overlapping inserts of Clones 1.4, 5d2, and 5d3 encoded ORFs similar to Escherichia coli partial genes serA and pgk, and complete genes rpiA, iciA, yggE, yggB and fda. These genes encode D-3-phosphoglycerate dehydrogenase (serA), ribose 5-phosphate isomerase (rpiA), a specific inhibitor of chromosomal initiation of replication (iciA), a hypothetical protein (yggE), a protein involved in responses to osmotic stress (yggB), fructose 1,6-bisphosphate aldolase (fda), and phosphoglycerate kinase (pgk). Cloned antigenic E. ictaluri proteins of 33, 27, 35 and 45 kDa appeared to be products of the ORFs similar to yggE, rpiA, iciA, and fda respectively. All the cloned antigenic proteins were recognized by antiserum from catfish that had recovered from enteric septicemia of catfish (ESC), indicating that these antigens are expressed during the infectious process. The cloned antigenic proteins were subsequently evaluated as subunit vaccines for protection against wild-type E. ictaluri. All vaccine treatments were protective against E. ictaluri in catfish, but results were inconclusive due to high levels of cross-reactive protection afforded by the E. coli host strain of the cloning vector.

This allowed the determination of the episodes characterized by the air mass transport to Africa and the Mediterranean region. Numerical simulation of one of such episodes, also characterized by intense cyclone and dust plume development, was performed using the Eta weather and dust predicting system. The simulation allowed an evaluation of the vertical distribution of the pollutants in the cyclone. Backward trajectories, ending in the area of the cyclone development point to the origin of a part of its air masses over the Arabian Sea. Potential role of the eastern Mediterranean weather systems in the transport to Europe of the polluted air masses from the INDOEX area is discussed. JF - Journal of Geophysical Research. D.

The intrusion has been associated with development of an intense cyclone over Africa. The weather and dust development processes were simulated with the Eta weather and dust prediction model. Also presented is a comparison of the model results with the Total Ozone Mass Spectrometer Aerosol Index (TOMS AI) pictures as well as with those of the surface and weather observations. The roles of the main processes responsible for the dust plume development and associated dust intrusion to the eastern Mediterranean (EM) are studied. The observation data as well as the model-simulated parameters are jointly analyzed. The analysis also includes the data from the back-trajectory computations. With the aid of the model-produced dust profiles we studied the significant variation in the altitudes of the dust layers within the cyclone sectors. In the warm sector of the cyclone located over the Mediterranean Sea the dust layer extended up to 8-10 km. Relatively low dust concentration values were found here. In the area of the cold front over Africa the dust was restricted to the lower troposphere and the planetary boundary layer. Here the model simulated high values of the dust concentrations. The sharp TOMS AI increase over Israel and the eastern Mediterranean up to 5.0 units, further away from the dust sources, is explained by the strong winds, by the increased cyclone convergence, and the formation of a two-layer dust plume.

Residential combustion takes place in homes for heating or cooking purposes and is thought to contribute a large fraction of the global burden of anthropogenic primary particles. We present optical properties and size distributions of particulate matter emitted from three types of coal burned in residential combustors: bituminous coal, hard coal briquettes, and lignite. Emissions from these coals differ significantly and can be partially explained by differences in coal composition. For bituminous coal, particulate matter emission factors are somewhat greater than those used in current emission inventories. We observe particles for which the light absorption is weak and has a strong spectral dependence. For hard coal briquettes and lignite, emitted light absorption is low, and based on our measurements, current inventories of light-absorbing aerosols significantly overestimate the contribution from these sources. Hard coal briquettes produce very few particles in the optically active size range. For all coals tested the size distributions required to represent the average of the emitted particles are broader than atmospheric size distributions, with geometric standard deviations between 2.2 and 3.0.

AN - 72780348; 12487307 AB - Atmospheric deposition is a significant loading pathway for polychlorinated dibenzo-p-dioxins and dibenzofurans (dioxin) to the Great Lakes. An innovative approach using NOAA's HYSPLIT atmospheric fate and transport model was developed to estimate the 1996 dioxin contribution to each lake from each of 5,700 point sources and 42,600 area sources in a U.S./Canadian air emissions inventory. These unusually detailed source-receptor modeling results show that deposition to each lake arises from a broad geographical region, with significant contributions from up to 2,000 km away. The source categories contributing most significantly to 1996 dioxin deposition appear to be municipal waste incineration, iron sintering, medical waste incineration, and cement kilns burning hazardous waste. Model-predicted air concentrations and deposition fluxes were consistent with ambient measurement data, within the uncertainties in each, but there may be a moderate tendency toward underestimation using midrange emissions estimates. The most likely reason for this tendency appears to be missing or underestimated emissions sources, but in-situ atmospheric formation of octachlorinated dibenzo-p-dioxin (OCDD) and heptachlorinated dibenzo-p-dioxin (HpCDD) may have also contributed. Despite uncertainties, the findings regarding the relative importance of different sources types and source regions appear to be relatively robust and may be useful in prioritizing pollution prevention efforts.

Their topologies and the locations of the RNA-binding sites vary considerably, consistent with the plasticity of RNA due to base pair mismatches, bulges, and loops. Yet the protein-binding surfaces can be recognized because they are enriched with positively charged residues that either form salt bridges with the negatively charged RNA or contribute favorably to the electrostatic environment. Protein regions that exhibit conformational flexibility are also good candidates for RNA-protein interactions because binding is usually accompanied by some mutual conformational adjustments. We have determined the crystal structure of HI1333 (YhbY) from Haemophilus influenzae, a protein annotated as hypothetical in sequence databases. We propose that this protein and its close sequence relatives (25 in the nonredundant sequence database at the time of writing) comprise a new class of RNA-binding proteins.

In spite of this extraordinary input, the ensuing 1981 year class was relatively poor. An examination of the feeding habits of larvae collected from inside and outside dense larval patches revealed that in 1981, larval walleye pollock consumed significantly more invertebrate eggs (x = 66.7% of the total diet) and fewer copepod nauplii (x = 13.6%) inside of larval patches relative to outside (x = 11.4 and 63.2%, respectively). These observations suggest that density dependent competition inside patches may have locally depleted the primary food source, copepod nauplii, prompting a diet switch to a lower quality but more abundant prey resource, invertebrate eggs. Results from a bioenergetics simulation support this theory, indicating that dense patches of walleye pollock larvae in 1981 were capable of exhausting naupliiar prey resources in Shelikof Strait in a relatively short period of time (14 to 40 d). Our observations contrast with other studies that suggest that ichthyoplankton exert little or no influence on microzooplankton standing stocks. Rather, we present evidence that, in certain unusual circumstances, particularly dense aggregations of larvae are capable of locally depleting the prey community. Such events may weaken larval condition and exacerbate natural death rates, which may have contributed to the poor recruitment success of the 1981 year class.

Some potential trade-offs include behavioral conflicts between foraging and avoiding predators, and physiological aspects of energy allocation between synthesis of new tissue and functional demands of metabolism and maintenance. We examined the capacity for compensation and some potential underlying mechanisms in juveniles of 2 northern Pacific fish species, walleye pollock Theragra chalcogramma and sablefish Anoplopoma fimbria. Fish were deprived of food for 2 to 3 wk, then returned to ad libitum rations. Growth rates were subsequently compared to those for continually fed fish for up to 16 wk, and potential trade-offs in behavior (food consumption, routine swimming speeds, and response to a predator) and physiology (indexed by critical swimming speeds) were examined during 3 time periods: immediately after deprivation, after 4 wk of ad libitum rations, and after 9 wk. We distinguished between routine swimming speeds, which indicate volitional motor activity, and critical swimming speeds, which estimate physiological capacity by forcing fish to swim to exhaustion against an increasing current. Previously deprived walleye pollock exhibited a clear, sustained capacity for accelerated growth, allowing them to quickly catch up in size to continually fed fish. Sablefish, however, exhibited only a minor level of growth compensation. Underlying mechanisms of compensatory growth also differed between the 2 species. Previously deprived walleye pollock increased food consumption to levels 3 to 4x greater than those of control fish and reduced energy expenditure by lowering routine swimming speeds. Compensating sablefish did not differ from control fish in consumption rates or routine swimming, but had lower critical swimming speeds than control fish, suggesting a trade-off in energy allocation. Responses to a simulated predator threat did not differ between previously deprived and continually fed fish of either species. The experimental results are suggestive of different mechanisms, behaviorally based for walleye pollock and physiologically based for sablefish, associated with accelerated growth. The differences between the 2 species in integrated processes of growth, behavior, and physiology are likely to be a function of their contrasting life history strategies and different baseline growth rates.

But who belongs to this floating population? Although this term conjures up images of unsettled persons lacking permanent residence, it is often used ambiguously or denotes distinctly different groups of people. This paper discusses these ambiguities and identifies a variety of definitions that we think are pertinent. The clarification of these definitions leads to a discussion of major sources of data (censuses, migration surveys and household registration lists). Along the way, we review some key empirical findings on China's floating population. We also discuss factors that have affected recent trends and are likely to affect future trends in migration and the floating population.

Census 2000 Special Reports. AN - 62162714; ED477270 AB - This report consolidates U.S. Census information from 1900-2000 to illustrate population changes over the 20th century. The population more than tripled, from 76 million in 1900 to 281 million in 2000. It grew increasingly metropolitan each decade. In 1900, half of the population was under 22.9 years old. By 2000, half of the population was over 35.3 years old. During the century, the population over age 64 increased tenfold. The country's gender composition shifted from majority male to majority female around midcentury. From 1900-2000, the number of non-southern states with populations of at least 10 percent races other than White increased from 2 to 26, reflecting the spread of diversity nationwide. From 1980-2000, the Hispanic population more than doubled. By 2000, California, Hawaii, New Mexico, and the District of Columbia had predominantly minority populations. Before 1950, over half of all occupied housing units were rented. By 1950, homeownership became more prevalent than renting. At the end of the 20th century, householders who were Black, Hispanic, or two or more races were more likely to rent than own their homes. In 1900, the most common household contained seven or more people. From 1940-2000, it contained two people. Between 1950-2000, married couple households declined from more than three-fourths of all households to just over one-half.

Kavachi, episodically active since at least 1939, is a forearc volcano located on the Pacific plate only approximately 30 km northeast of its convergent boundary with the downgoing Indo-Australian plate. During 14 May 2000 we observed explosive phreatomagmatic eruptions at several minute intervals, creating a complex distribution of plumes of volcanic glass shards throughout the water column at a distance of approximately 1.5 km from the summit. At distances of 4-5 km, shallow-water (<250 m) plumes had dissipated, but deeper plumes were ubiquitous down to seafloor depths of 1500 m. Only 2 of 22 water samples (at 14 and 237 m depth) showed evidence of hydrothermal and magmatic enrichment. These samples were elevated in delta (super 3) He, Fe, and Mn (one sample only), but not in CO (sub 2) . We infer that the volcano flanks were essentially impermeable to fluid emissions and that the observed particle halo was created by magma shattering and resuspension. Most magmatic and hydrothermal fluids were thus discharged directly from the summit into the atmosphere.

Hazard mitigation, an important part of sustainable development, eliminates or minimizes disaster-related damages and empowers communities to respond to and recover more quickly from disasters. The Community Vulnerability Assessment Tool (CVAT) is a risk and vulnerability assessment methodology designed by the national Oceanic and Atmospheric Administration's Coastal Services Center to assist emergency managers and planners in their efforts to reduce hazard vulnerabilities through hazard mitigation, comprehensive land-use, and development planning. CVAT analysis results provide a baseline to prioritize mitigation measures and to evaluate the effectiveness of those measures over time. This methodology is flexible, as results may be achieved using a geographic information system or static maps with overlays and handwritten data. This paper outlines how to engage stakeholders and explains the CVAT process. Several case studies also highlight some of the challenges/problems and best practices/opportunities associated with applying the CVAT methodology.

Scats were collected from 1990-1998 on island sites across most of the range of the United States western stock of the species. Walleye pollock (Theragra chalcogramma) and Atka mackerel (Pleurogrammus monopterygius) were the 2 most common species of prey, followed by salmonids (Oncorhynchus) and Pacific cod (Gadus macrocephalus). An additional 16 species of fish and unidentified cephalopods were considered primary in the diet, either because they occurred in >5% of scats collected across the range in winter and summer or because they consistently occurred among the top 3 prey items in particular islands or island groups. Capelin (Mallotus villosus) occurred at very low frequencies despite their predominance in the diet of Steller sea lions before the 1980s. Regions of diet similarity suggest area-specific foraging strategies, with strong seasonal patterns in consumption of most species of prey. Patterns in prey consumption and characteristics of prey indicate that Steller sea lions target prey that are densely schooled in spawning or migratory aggregations at the continental shelf or along oceanographic boundary zones. We suggest that regional diet patterns among the western stock reflect regional foraging strategies of females learned at islands near the natal rookery site.

Three subdivisions of the river were identified for the study: upstream from, adjacent to, and downstream from the city of Savannah. There was high spatial variability in the total PAH (DPAH) concentrations that ranged from 29 to 5,375 ng/g with an average concentration of 1,216 - 1,161 (SD). Of the three subdivisions, the highest DPAH concentrations were in the middle segment, which was adjacent to urban and industrial areas. To elucidate sources, molecular indices based on indices among phenanthrene versus anthracene and fluoranthene versus pyrene were used to determine pyrogenic and petrogenic sources, respectively. These indices have been used by other authors to differentiate sources. In most cases, PAHs in sediments nearest the city of Savannah were of high temperature and pyrogenic origin. These pyrogenic PAHs were highly associated with toxicity to benthic organisms. The two-ringed naphthalene and substituted naphthalenes, which are petroleum-related PAHs, were significantly higher in the lower section of the river relative to the subdivisions. This river segment receives inputs primarily from shipping and boating traffic. Perylene, which is indicative of nonanthropogenic terrestrial inputs of carbon, had the highest concentration among the individual PAHs measured. High perylene concentrations were found at stations located upstream and adjacent to forested terrain and where salinity level was low. To discriminate pattern differences and similarities of individual PAHs among samples, principal component analysis (PCA) was performed on the more hydrophobic and persistent nonalkylated PAHs. These differences and similarities were used to infer perylene origin. PCA was performed on 14 nonalkylated PAHs that was normalized to the sum of nonalkylated PAHs, using a correlation matrix. Generally, the PAHs were separated into group patterns according to chemical and physical properties associated with log K sub(OW), except perylene. Perylene, a five-ringed PAH, was distinctly separated from the other five-ringed PAHs. The sources for perylene are likely from biogenic, terrestrial precursors. The collected data show that pyrogenic PAHs were highly associated with biological effects on benthic organisms, based on bioassay results. Perylene, a nonanthropogenic PAH, was found throughout the river and constituted a large percentage of total PAHs in the upper river.

Sampling of macroinfauna, sediments for toxicity and chemical contaminant analyses, and physical properties of water was carried out synoptically over a four-day period at 20 stations from the mouth of the Neuse River at Pamlico Sound to approximately 90 km upstream. The distribution and condition of benthic infauna were found to vary in response to natural and anthropogenic factors, and apparent associations between degraded infaunal condition and sediment contamination and/or toxicity were observed over roughly half of the sampled area (7 stations, 47% area). With few exceptions, degraded benthic conditions were associated with significant sediment contamination or toxicity. High sediment contaminant levels were found to occur almost exclusively in fine-grained, organic-rich muds. These results suggest that high organic loading and chemical contaminant inputs to the Neuse River, coupled with low freshwater discharge rates and high residence times in the lower estuary, have contributed to degraded benthic conditions at these sites.

ER - TY - JOUR T1 - Spatial characterization, resolution, and volumetric change of coastal dunes using airborne LIDAR: Cape Hatteras, North Carolina AN - 18910283; 5495015 AB - The technological advancement in topographic mapping known as airborne Light Detection and Ranging (LIDAR) allows researchers to gather highly accurate and densely sampled coastal elevation data at a rapid rate. The problem is to determine the optimal resolutions at which to represent coastal dunes for volumetric change analysis. This study uses digital elevation models (DEM) generated from LIDAR data and spatial statistics to better understand dune characterization at a series of spatial resolutions. The LIDAR data were collected jointly by the National Aeronautics and Space Administration (NASA), the National Oceanic and Atmospheric Administration (NOAA), and the U.S. Geological Survey (USGS). DEMs of two study sites (100 x 200 m) located in Cape Hatteras National Seashore, North Carolina were generated using a raster-based geographic information system (GIS). Changes in the dune volume were calculated for a 1-year period of time (Fall 1996-1997) at grid cell resolutions ranging from 1 x 1 to 20 x 20 m. Directional statistics algorithms were used to calculate local variance and characterize topographic complexity. Data processing was described in detail in order to provide an introduction to working with LIDAR data in a GIS. Results from these study sites indicated that a 1-2 m resolution provided the most reliable representation of coastal dunes on Cape Hatteras and most accurate volumetric change measurements. Results may vary at other sites and at different spatial extents, but the methods developed here can be applied to other locations to determine the optimum resolutions at which to represent and characterize topography using common GIS and database software.

Effects of land processes on variability of monthly river discharge AN - 18904541; 5581879 AB - A salient characteristic of river discharge is its temporal variability. The time series of flow at a point on a river can be viewed as the superposition of a smooth seasonal cycle and an irregular, random, variation. Viewing the random component in the spectral domain facilitates both its characterization and an interpretation of its major physical controls from a global perspective. The power spectral density functions of monthly flow anomalies of many large rivers worldwide are typified by a "red noise" process: the density is higher at low frequencies (e.g., <1 y super(-1)) than at high frequencies, indicating disproportionate (relative to uncorrelated "white noise") contribution of low frequencies to variability of monthly flow. For many high-latitude and arid-region rivers, however, the power is relatively evenly distributed across the frequency spectrum. The power spectrum of monthly flow can be interpreted as the product of the power spectrum of monthly basin total precipitation (which is typically white or slightly red) and several filters that have physical significance. The filters are associated with (1) the conversion of total precipitation (sum of rainfall and snowfall) to effective rainfall (liquid flux to the ground surface from above), (2) the conversion of effective rainfall to soil water excess (runoff), and (3) the conversion of soil water excess to river discharge. Inferences about the roles of each filter can be made through an analysis of observations, complemented by information from a global model of the ocean-atmosphere-land system. The first filter causes a snowmelt-related amplification of high-frequency variability in those basins that receive substantial snowfall. The second filter causes a relatively constant reduction in variability across all frequencies and can be predicted well by means of a semiempirical water balance relation. The third filter, associated with groundwater and surface water storage in the river basin, causes a strong reduction in high-frequency variability of many basins. The strength of this reduction can be quantified by an average residence time of water in storage, which is typically on the order of 20-50 days. The residence time is demonstrably influenced by freezing conditions in the basin, fractional cover of the basin by lakes, and runoff ratio (ratio of mean runoff to mean precipitation). Large lake areas enhance storage and can greatly increase total residence times (100 to several hundred days). Freezing conditions appear to cause bypassing of subsurface storage, thus reducing residence times (0-30 days). Small runoff ratios tend to be associated with arid regions, where the water table is deep, and consequently, most of the runoff is produced by processes that bypass the saturated zone, leading to relatively small residence times for such basins (0-40 days).

Yet due to the correlative nature of time series data, these undertakings have been statistically problematic. Most analyses of density dependence have focused on simple population models (i.e., non-overlapping generations), but in reality most vertebrates exhibit more complex life histories, and this complexity has been incorporated into population models in a variety of ways. Unfortunately, adding complexity to population models can further exacerbate efforts to detect density dependence. We examined the effect of adding age structure when inadequate data exist in support; to demonstrate this effect, we adopted Pacific salmon (Oncorhynchus spp.) as our study organism. Most salmon populations are semelparous and have variable age at maturity. Salmon populations (and many other fish species populations) are typically modeled in terms of numbers of recruits arising from spawners in a given brood year. Recruits are enumerated as they return as adults to spawn, and proper assignment of recruits to brood year requires age information. Unfortunately, while adult counts are common, detailed age information is not. A common practice is to apply long-term averages of age composition to returning adults to "reconstruct" time series of recruits. Here, by conducting simulations and analyzing data from natural populations, we demonstrated that this practice leads to a biased portrayal of density dependence by overestimating recruits from small spawning classes and underestimating recruits from large spawning classes. Also, productivity was overestimated and variance was underestimated, which could lead to overly optimistic predictions of extinction risk or overharvesting.

Indeed, the presence of one nonindigenous species can act as an agent of disturbance that facilitates the invasion of a second species. However, most studies of nonindigenous species are anecdotal and do not provide substantive evidence that interactions among nonindigenous species have any community-level effects. Here, using a combination of field experiments and observations we examine interactions among introduced species in New England kelp forests and ask whether these interactions have altered paradigms describing subtidal communities in the Gulf of Maine. The green alga Codium fragile was observed at the Isles of Shoals, Maine, USA, in 1983 and has since replaced the native kelp as the dominant seaweed on leeward shores. Experiments manipulating kelp and Codium reveal that Codium does not directly inhibit growth or survival of kelp. Codium does, however, successfully recruit to gaps in the kelp bed and, once established, inhibits recruitment of kelp. A second nonindigenous species, Membranipora membranacea, grows epiphytically on kelp, and experiments reveal that the presence of Membranipora reduces growth and survival of kelp, resulting in defoliation of kelp plants and gap formation in kelp beds. In the absence of Codium, kelp recolonizes these gaps, but when present, Codium colonizes and prevents kelp recolonization. Manipulations of herbivores demonstrate that herbivory will reinforce Codium dominance. Thus, the demise of New England kelp beds appears to result from one invasive species facilitating the spread of a second nonindigenous species.

Numerical simulation of data processing procedures indicates that this instrument has sufficient resolution to characterize zooplankton spatial distributions using Lloyd's index of patchiness and nearest neighbour distance (NND) measures. Zooplankters at this site were dominated by the euphausiid Euphausia pacifica which underwent diel vertical migration (DVM). Fish (mainly herring and walleye pollock) were only abundant at this deep-water station at night. Analysis of 4 m super(3) volumes over scales of approximately 100 m indicates that both euphausiids and fish were strongly aggregated in the vertical dimension, but not in the horizontal dimension. In the horizontal dimension, fish distributions were independent of zooplankton abundance indicating that the fish were not exploiting small-scale horizontal prey aggregations. Analysis of NND at the centimetre scale indicates that euphausiids were not aggregated, but rather, they were approximately randomly distributed These observations indicate that in this environment euphausiids do not form subsurface social aggregations as has been documented in other locations. DVM and social aggregation are both predator avoidance behaviours that may be redundant, as populations that exhibit pronounced DVM may derive little additional benefit from routine social aggregation.

The Gulf Stream and associated warm-core rings are hypothesized as the physical mechanisms responsible for the northward transport of larvae. Specifically, larvae spawned along the southeast U.S. continental shelf are entrained into the Gulf Stream, transported to the northeast, regularly incorporated in warm-core ring streamers, transported across the slope region, and released along the shelf edge north of Cape Hatteras. This proposed transport route was evaluated using hydrographic data and drifter tracks that were collected as part of other studies. Continental shelf water that originated south of Cape Hatteras was found along the edge of the Gulf Stream north of Cape Hatteras, and drifter tracks demonstrated each segment of the proposed transport route. A probability model was then developed to estimate transport times for larvae carried over the proposed transport route using a combination of sea surface temperature images, statistics of drifter transport speeds, and a larval mortality function. Modeled transport time distributions closely matched observed age distributions of larvae, further supporting the hypothesized transport route.

Hatching occurred 23 days after fertilization, followed by 6 days of larval incubation. Eggs varied in dry mass and energy content with lipid concentrations contributing the greatest amount of energy per egg. The endogenous energy of the yolk and oil globule declined throughout gestation resulting in limited yolk and oil reserves at parturition. Copyright 2002 The Fisheries Society of the British Isles.

High haplotypic diversity (H = 0.975) and a poorly resolved mitochondrial genome (mtDNA) phylogeny suggest that harbor seals in the Pacific underwent a rapid expansion in population size in their recent evolutionary past, possibly after the retreat of Pleistocene ice sheets. Weak phylogeographic partitioning of lineages attests to a complex evolutionary and demographic history of contemporary Pacific populations. Extensive macrogeographic subdivision was evident among a subset of grouped localities that represent centers of abundance along the distributional continuum. Heterogeneity was influenced by population size and correlated with geographic distance, suggesting that dispersal occurs primarily among neighboring subpopulations. The 2 currently recognized subspecies of harbor seal in the Pacific, P. v. richardii of North America and P. v. stejnegeri of Asia, do not represent phylogenetically discrete mtDNA assemblages. The greatest differentiation detected was along the Commander-Aleutian Island chain, the region of the presumed subspecies boundary and a likely contact zone for expanding refugial populations of a number of marine mammal species after retreat of ice sheets. Differentiation between the Kodiak Archipelago and Prince William Sound, and between Bristol Bay and the Pribilof Islands, indicates that current management stocks are inappropriate and highlights the need for a detailed analysis of population and stock structure in Alaska. A decline in population size in Prince William Sound over the past few decades was accompanied by a discernible reduction in mtDNA diversity, manifested as a loss of rare haplotypes through random drift. A continued population decline will erode genetic diversity further, with potentially adverse effects on evolutionary potential and individual fitness.

R. salmoninarum has two identical copies of the gene encoding major soluble antigen (MSA), an immunodominant, extracellular protein. To determine whether one or both copies of msa are expressed, reporter plasmids encoding a fusion of MSA and green fluorescent protein controlled by 0.6 kb of promoter region from msa1 or msa2 were constructed and introduced into R. salmoninarum. Single copies of the reporter plasmids integrated into the chromosome by homologous recombination. Expression of mRNA and protein from the integrated plasmids was detected, and transformed cells were fluorescent, demonstrating that both msa1 and msa2 are expressed under in vitro conditions. This is the first report of successful transformation and homologous recombination in R. salmoninarum.

Three years of collocated rainfall estimates from radar, rain gauges, a microwave satellite algorithm, and a multispectral (visible through near-infrared) algorithm were collected over the continental United States from July 1998 through July 2001. The radar and gauge data are compared to determine the locations and times at which the rainfall occurrences estimated by these two sensors are in sufficient agreement for the data to be used for validation. This procedure serves as quality control for both sensors and determines the locations at which the radar has difficulty detecting rainfall and should not be used in a validation dataset. For the data remaining after quality control, the gauge data are used for multiplicative adjustment of the radar estimates to remove the radar bias with respect to the gauges. These bias-adjusted estimates are compared with the satellite rainfall estimates to observe the evolution of the satellite biases over the 3-yr period. The multispectral algorithm was under development throughout the 3-yr period, and improvement is evident. The microwave algorithm overestimates rainfall in the summer months, underestimates in the winter months, and has an east-to-west bias gradient, all of which are consistent with physical explanations and previous findings. The multispectral algorithm bias depends highly on diurnal sampling; there is much greater overestimation for the daytime overpasses. These results are applicable primarily to the eastern half of the United States, because few data in the western half remain after quality control.

Likewise, little is known concerning the interaction between UV and xenobiotic exposure on crustacean reproductive cycles. In this study, male and female grass shrimp, Palaemonetes pugio, were exposed to sublethal concentrations of endosulfan (200 ng/l and 400 ng/l ES) under both white fluorescent (WF) and UV-A (315-400 nm) light conditions for 50 days in laboratory bioassays. Female endocrine (vitellogenin, ecdysteroids, and cholesterol), reproductive (percent gravid, clutch size), and embryo (days to hatch, hatching success, and hatching survival) responses were assessed. UV-exposure alone caused a significant (>4-fold) increase in total Palaemonetes pugio female egg production over the course of 50 days. Exposure to ES and UV significantly lowered the percentage of gravid females relative to UV controls, whereas ES-exposed shrimp under WF lighting did not exhibit these trends. Although higher vitellogenin concentrations and lower ecdysteroid titers were correlated with increased female egg production, cholesterol titers only exhibited a dose-dependent change when exposed to ES. Embryos from females exposed to UV had significantly lower ecdysteroid titers and shorter hatching times but there were no differences in embryo vitellogenin concentrations, hatching success, or hatching survival. These results indicate that UV-A exposure has a pronounced effect on grass shrimp (Palaemonetes pugio) reproduction and is likely mediated through 5-hydroxytrptamine (5-HT)-related neuroendocrine pathways. The implications for decapod aquaculture and evaluating chronic contaminant effects are discussed.

AN - 16351562; 9669 AB - PURPOSE: The implementation of a revised fishery management plan (FMP) for American lobsters in the exclusive economic zone (EEZ) along the North Atlantic coast is proposed. The revised plan would respond to an addendum to the Atlantic States Marine Fisheries Commission's Interstate Fisheries Management Plan for the species. In short, the addendum requests federal authorities to control fishing effort as determined by historical participation in the American lobster trap fisheries conducted in the offshore Lobster Conservation Management Area (LCMA) 3 and in the nearshore LCMAs of the EEZ from New York through North Carolina (Areas 4 and 5); to implement a mechanism for conservation equivalency and associated trap limits for owners of vessels in possession of a federal lobster permit fishing offshore of New Hampshire; and to clarify lobster management area boundaries in Massachusetts waters. A stock assessment published in March 2000 by federal scientists concluded that lobsters were overfished in all the pertinent stock assessment areas; the problem is aggravated by increased fishing effort, which will deplete stocks even further if unchecked. Six management alternatives for the trap/pot lobster fishery, including an alternative to maintain the status quo, were considered in the draft EIS of March 1998. The alternative preferred in the final EIS of April 1999 would involve continuation of certain measures as well as implementation of new measures. The preferred management action described in this final supplement to the final EIS would include implementation of historical participation measures to control effort by the lobster trap fishery in three Lobster Conservation Management Areas (LCMAs); implementation of conservation-equivalent trap limits in New Hampshire waters of one LCMA; and clarification of lobster management area boundaries. The preferred action would include qualification criteria for participation, trap allocation requirements, trap reduction stipulations, vessel upgrade requirements, fishing season limitations, provisions for entry into agreements with state authorities to determine fulfillment of qualification criteria for two LCMAs, minimum take size stipulations, and area closures. POSITIVE IMPACTS: The alternatives would protect the lobster industry from the effects of overfishing. The spawning stock size and yield per recruit would increase significantly. The decline in ghost gear would generally improve the marine habitat associated with the fishery. Risks to marine mammals and sea turtles associated with the presence of trap fishing gear would decline significantly. NEGATIVE IMPACTS: Restrictions on fishery entry and harvest, including trap allocation requirements and trap reduction stipulations, could create a temporary economic hardship for certain lobster operations.

Evaluation AN - 16156758; 5653265 AB - The Community Multiscale Air Quality (CMAQ) modeling system has been adapted to simulate the regional fate and transport of atrazine. Model modifications and simulations spanning April to mid-July 1995 are described in a previous paper. CMAQ results for atrazine concentrations in air and rainfall are evaluated against field observations taken along the Mississippi River and the shores of Lake Michigan in 1995. CMAQ results agree within 10% of published annual wet deposition load estimates for Lake Michigan and predicted annual dry deposition lies within published error bounds. Comparisons of weekly observed and predicted air and rainfall concentrations along the Mississippi River yield order-of-magnitude differences. Precipitation weighting of concentrations in rainfall good agreement for seasonal time frames. Weekly ambient gas form concentrations tend to be overpredicted by the CMAQ and semivolatile particulate fractions are underpredicted. Uncertainty in CMAQ predictions of air and rainfall concentrations for atrazine appear to derive primarily from uncertainty in emissions estimates, simulated precipitation, and spatial scale.

Rockfish larvae occurred in relatively high densities near surface fronts and were distributed in patches oriented along sloping pycnoclines contiguous with surface fronts. Qualitative comparisons between observed distributions of larval rockfishes in relation to hydrographic structure and predictions from models of plankton distributions at convergent fronts support the hypothesis that convergent circulation contributes to observed distributions. Our results indicate that (1) coastal upwelling fronts influence larval rockfishes at an earlier life history stage than has previously been documented, and (2) the influence of upwelling fronts on distributions of larval rockfishes is similar to the influence of hydrographic fronts on distributions of larval fish reported for a variety of oceanographic settings. In light of the plausible effects of upwelling fronts on larval transport and ecology, our findings suggest that upwelling fronts merit further investigation for their potential role in translating variability in upwelling dynamics into fluctuations in recruitment to coastal rockfish populations along the west coast of North America.

Efforts to recover regional green turtle populations have been hampered by a lack of information on their biology. In particular, turtle movements and home ranges in neritic foraging habitats are not well understood. Thus, wildlife managers cannot accurately determine the habitat needs of green turtle populations. To address these understudied aspects, we carried out the first ever investigation of green turtle home range in neritic foraging habitats of the eastern Pacific Ocean. Twelve turtles, ranging from 50.9 to 82.5 cm in straight carapace length and from 17 to 70 kg in mass, were tracked with radio and sonic telemetry for 34 to 96 d at the Bahia de los Angeles foraging area in the Gulf of California, Mexico. Home range areas determined with minimum convex polygon and fixed kernel density estimator methods ranged from 584 to 3908 ha (mean = 1662 plus or minus 324 ha) and 409 to 3231 ha (mean = 1537 plus or minus 280 ha), respectively. There was no evidence that straight carapace length, mass, sex, tracking duration or number of re-sightings influenced the size of the home range. Green turtle home ranges contained from 1 to 3 activity centers ranging from 3.8 to 642.2 ha in area (mean = 178.8 plus or minus 62.0 ha). Turtles were re-sighted in all depth-class regions (0 to 10 m to 40+ m) in the study area but were not found with equal frequency among these regions. The distribution of re-sightings among depth classes varied significantly between diurnal (05:00 to 18:59 h) and nocturnal (19:00 to 04:59 h) periods. While the greatest frequency of diurnal re-sightings occurred in the 10 to 20 m depth class, nocturnal encounters were most frequent in the 0 to 10 m depth class. This study shows that Bahia de los Angeles remains an important feeding ground; thus, underscoring the need to develop conservation strategies that address the impacts of ongoing commercial marine-algae harvests and net fisheries that threaten green turtles in this region.

AN - 16362593; 9655 AB - PURPOSE: The establishment of an optimum yield (OY) and acceptable biological catch (ABC) for the Pacific Coast groundfish fishery is proposed. The Pacific Coast Groundfish Fishery Management Plan (FMP) establishes a framework authorizing the range and type of measures that may be used to exploit the fishery, enumerates 18 objectives, under three broad categories, that management measure must satisfy, and describes more specific criteria for determining the level of harvest that will provide the greatest overall benefit to the nation. Fisheries subject to the management measures include limited entry trawl fisheries, limited entry fixed gear (pot and longline) fisheries, and a variety of other fisheries catching groundfish, either as target species or incidentally?, but not license limited under the management framework established in the FMP. Allocations to tribal fisheries in Washington state are also identified. To date, nine groundfish species have been declared overfished and measures to prevent overfishing and rebuild these overfished stocks are a central element of this actin. The proposed actin would establish harvest guidelines for groundfish species, species groups, and geographic subunits. In order to constrain fisheries to these harvest guidelines. management measures for commercial and recreational fisheries are identified. Management measures considered for commercial fisheries would include two-month cumulative landing limits for species, species groups, and geographic subunits for limited entry trawl and fixed gear sectors and fisheries not license limits under the FMP, as well as gear restrictions to reduce bycatch of overfished species and reduce habitat impacts. Management measures considered for recreational fisheries would include bag limits, size limits, and fishing seasons; these measures would vary by state. In addition, area closures, based on depth and intended to reduce bycatch of species would apply to both commercial and recreational fisheries that are likely to catch these species; these closures would vary by geographic region. Five alternatives, including a No Action Alternative, are considered in this draft EIS. POSITIVE IMPACTS: The establishment of the ABC and the OY specifications would ensure that Pacific Coast groundfish subject to federal management are harvested in an manner by which sustainable use of these fishery resources can be maintained, supporting economic exploitation of the fishery and maintaining fishery stocks at appropriate levels for regeneration. NEGATIVE IMPACTS: Depending on the alternative selected, commercial fisheries would lose $12.8 million $22 million in direct ex-vessel revenues, while recreational fisheries would lose $1.2 million to $25.7 million. The OYs for the overfished species would likely be exceeded, possibly requiring more severe restrictions in the future. Buyers and processors would also lost about $12 million to $22 million in gross value of purchases under this alternative. Communities would lose $35.3 million to $52.5 million in income under this scenario. Enforcement costs could increase.

AN - 16349414; 9632 AB - PURPOSE: The improvement of 17 miles of Louisiana (LA) 1 in Lafourche Parish, Louisiana is proposed. From Interstate 10 (I-10) at Port Allen to LA 3090 at Port Fourchon, LA 1 is designated as a principal arterial within the National Highway System due to the facilities intermodal link to a major portion of the nation's energy supply. As the only highway in the area, LA 1 is the sole transportation route for workers and supplies entering and existing Port Fourchon and is the only hurricane evacuation route for thousands of residents in south Lafourche Parish. The new facility would be a four-lane, divided, fully controlled access elevated highway on new alignment paralleling existing LA 1 between Louisiana (LA) 3235 west of Golden Meadow and LA 3090 at its intersection with Louisiana 1, north of Port Fourchon. Bridges would span navigable waterways. Access to the facility would be limited to on and off ramps and two-lane connector roads constructed on new location at proposed interchange locations at LA 3235, LA 1 at Leeville, and LA 3090. Four alignment alternatives and a No Action Alternative are considered in this final EIS. The preferred alternative (Line A) Construction of the project could be staged or programmed for discrete construction as funding permits. Estimated cost of the project is $523.2 million. With the exception of the Leeville Lift-Bridge, existing LA 1 would remain in service following completion of the new facility, though administration of the old facility would be transferred to local authorities. POSITIVE IMPACTS: The project would complete the southernmost portion of the principal arterial, connecting the facility to LA 3235, an existing four-lane divided highway west of Golden Meadow. Once completed, a four-lane divided highway facility would be available from LA 3090 north of Port Fourchon to north of Galliano, Louisiana. Emergency response to hazardous materials and oil spills would be enhanced. NEGATIVE IMPACTS: Rights-of-way requirements would result in the displacement of one house, one mobile home, and one business. The project would also displace 5.3 acres of wetlands, 16.34 acres of floodplain, and 0.1 acre of prime farmland soils. Portions of the project corridor are likely to contain archaeological resource sites, and the project rights-of-way would encompass one oil and gas well. Noise levels would exceed federal standards in the vicinity of three sensitive receptors.

AN - 85357510; pmid-12398433 AB - The idea of similarity between acoustic fields in a moving fluid and in a certain "effective" quiescent medium, first put forward by Lord Rayleigh, proved very helpful in understanding and modeling sound propagation in an atmosphere with winds and in an ocean with currents, as well as in other applications involving flows with small velocity compared to sound speed. Known as effective sound speed approximation, the idea is routinely utilized in the contexts of the ray theory, normal mode representation of the sound field, and the parabolic approximation. Despite the wide use of the concept of effective sound speed in acoustics of moving media, no theoretical justification of Rayleigh's idea was published that would be independent of the chosen representation of the sound field and uniformly apply to distinct propagation regimes. In this paper, we present such a justification by reducing boundary conditions and a wave equation governing sound fields in the inhomogeneous moving fluid with a slow flow to boundary conditions and a wave equation in a quiescent fluid with effective sound speed and density. The derivation provides insight into validity conditions of the concept of effective quiescent fluid. Introduction of effective density in conjunction with effective sound speed is essential to ensure accurate reproduction of acoustic pressure amplitude in the effective medium. Effective parameters depend on sound speed, flow velocity, and density of the moving fluid as well as on sound propagation direction. Conditions are discussed under which the dependence on the propagation direction can be avoided or relaxed.

AN - 72759234; 12474962 AB - Northern fur seals from the Pribilof Islands, Alaska (St. George Is. and St. Paul Is.) were examined for organochlorine contamination (OC) and whether the organochlorine levels differed between the populations and were at levels that may adversely affect their health. Fur seal blubber and milk samples were obtained from pups, sub-adult males, and adult females on both Pribilof Islands. These samples were analyzed for organochlorine contaminants including dioxin-like PCBs and other selected PCBs and pesticides by high performance liquid chromatography/photodiode array. Results showed that there are clear differences between the two islands in the patterns of fur seal OC distribution. Generally, these differences are confined to the PCBs with only minimal differences in the DDTs. There are also clear biological differences in the levels shown between milk, pup blubber, and sub-adult male blubber. When considering blubber, St. George Is. fur seals show higher OC levels than St. Paul Is., for both pups and sub-adults. On the other hand, milk samples from St. Paul Is. showed higher PCB levels than St. George Is. For the milk, the overall OC levels may impact the immune function of the pups, but are probably of only minimal impact to humans. However, for blubber, the overall toxic equivalency shows levels exceeding those levels recommended for human consumption at St. George Is. and approaching those levels at St. Paul Is. The concentration curves suggest that the movement of OC in and out of milk follows a complex set of reactions dependent on how the OC compounds on a congener level are associated with lipid. In fact, there is some evidence that they may not follow the lipid as closely as we had thought and that lipid levels can vary without impacting the total OC level in the milk.

AN - 72162405; 12371497 AB - Two previous mesocosm studies showed changes in glucosephosphate isomerase-2 (Gpi-2) allele frequencies in mosquitofish populations exposed to mercury for 111 d or two years. A previous selection component analysis of single-generation populations exposed for 111 d to 18 microg/L Hg suggested that female sexual selection and fecundity selection could contribute to changes in Gpi-2 allele frequencies. The present multigeneration study was conducted to determine the stability of Gpi-2 allele frequencies over four years of mercury exposure, measure the reproductive fitness of Gpi-2 genotypes inhabiting control and mercury-contaminated mesocosms to determine a mechanism explaining changes in Gpi-2 allele frequencies, investigate differences in the demographic characteristics of mercury-exposed and control populations, and investigate the water quality of the mesocosms to determine if variables other than mercury show concordant patterns among mesocosms. Differences in Gpi-2 allele frequencies between control and mercury-exposed populations were stable over four years (approximately eight generations) of mercury exposure. Mercury-exposed female mosquitofish had a lower probability of being gravid than control females (p = 0.001). Mercury-exposed females also had lower fecundity (total number of eggs and embryos) than control females (p = 0.036). Unlike the results of the more intense mercury exposures in the single generation study, no strong evidence was found that Gpi-2 genotype influenced fecundity or the probability of being gravid in both control and mercury-exposed females. The quantification of fitness components is difficult but has the potential to enhance our understanding of how toxicants alter allele frequencies in exposed populations.

Current Population Reports. AN - 62231198; ED471048 AB - This report presents data on single parent families, focusing on the child support income that custodial parents reported receiving during the calendar year prior to the survey as well as other support provided, such as health insurance and non-cash support for children up to age 21 years. Data came from the April 2000 supplement to the Current Population Survey (CPS), which provides information for calendar year 1999. Results indicated that in 2000, custodial parents numbered 13.5 million. Poverty rates declined for custodial parents between 1993-99. More custodial parents worked in 1999, and participation in public programs was lower than in 1993. Demographic characteristics differed between custodial mothers and custodial fathers. About 59 percent of custodial parents had child support agreements in 2000. Custodial mothers were more likely than fathers to have child support awards. About three-quarters of custodial parents received at least some child support payments. Over half of child support awards had provisions for health insurance. Income was higher and poverty was lower for custodial parents receiving all child support due. Total requests for assistance related to child support declined between 1994-00.

This is illustrated for a suite for four samples of Fontainebleau sandstone with porosities ranging from 7.5% to 22%. A finite-element method is used to derive the elastic properties of digitized images. By estimating and minimizing several sources of numerical error, very accurate predictions of properties are derived in excellent agreement with experimental measurements over a wide range of the porosity. We consider the elastic properties of the digitized images under dry, water-saturated, and oil-saturated conditions. The observed change in the elastic properties due to fluid substitution is in excellent agreement with the exact Gassmann's equations. This shows both the accuracy and the feasibility of combining microtomographic images with elastic calculations to accurately predict petrophysical properties of individual rock morphologies. We compare the numerical predictions to various empirical, effective medium and rigorous approximations used to relate the elastic properties of rocks to porosity under different saturation conditions.

The Si-0 stretch and O-Si-O bond bending force constants determined for palygorskite are similar to equivalent values calculated previously for other phyllosilicates. The Mg-O bond stretch values, on the other hand, are about half of those determined for the equivalent Al-O and Mg-O bond stretch environments in other phyllosilicates, suggesting that the bonding within the octahedral ribbons in palygorskite and sepiolite is weaker than that in the continuous octahedral sheets in micas. The weaker bonding allows more flexible octahedral environments in palygorskite and sepiolite, giving rise to higher probabilities for cation substitutions and vacancies relative to the micas. Above approximately 700 cm (super -1) in the IR and 750 cm (super -1) in the Raman spectra, the eigenmodes are dominated by atomic displacements within the silicate sheets. Below 700 cm (super -1) the eigenmodes become mixed with motions among the Mg octahedra and the silicate sheets; the eigenmodes assigned to the most prominent peaks in the Raman spectra (near 700 cm (super -1) ) belong to this group. As mode frequencies decrease, the corresponding eigenmodes evolve from more localized Mg-O stretch, O-Mg-O bend and O-Si-O bend motions to longer-range motions such as silicate sheet deformations caused by silicate tetrahedra rotation and silicate sheet shearing around the Mg-octahedral sheets.

Mesh bags containing crabs, urchins, mollusks and wood were placed at depths from 15-300 m off the Bahamas carbonate platform and in a variety of depositional environments on the shelf and slope of the Gulf of Mexico (70-600 m). Upon recovery, each specimen was characterized as to degree of fragmentation, disarticulation, surface condition and infestation by bionts. After 6 to 8 years, shells within the photic zone are weakened, fragmented or lost. Much of this loss is biologically mediated. Shells deployed below 100 m are generally unaltered after 8 years, with the exception of discoloration and very minor dissolution in both carbonate and siliciclastic settings. However, taphonomic alteration is proceeding more quickly at petroleum seeps. These sites offer heterogeneous bottom conditions with strongly sulfurous pore waters. Dissolution, breakage, and edge alteration are more common here, but are restricted to regions in the immediate vicinity of the seep. Urchins and crabs were deployed frozen in 2-mm mesh pouches as part of each experimental array. After eight years all urchins had lost spines and the lantern had disarticulated, but a majority of urchins were recovered with the corona intact, even at 15 m depth. Chelipeds of the crab Callinectes were nearly always recovered and, below the photic zone, carapace fragments were also common. The endurance of echinoderm and crab remains despite lack of burial (and thus exposure to microbial activity, if not scavengers) is remarkable. Wood quickly became consumed by Teredo and limnorid isopods, particularly below the photic zone. Shallow deployments (above 100 m) show greater resistance to decay. Intermittent burial and overgrowth by encrusters likely slows the activity of the shipworms within the photic zone. This long-term experimental taphonomy project continues to provide invaluable information on the fate of organism remains. Hard parts exposed at the sediment/water interface within the photic zone will likely not survive more than 10-15 years, depending on species. Deeper shelf/slope settings exhibit a slower rate of taphonomic loss, with the exception of wood that is slightly more durable in shallow shelf settings.

A commonly employed lattice-matching strategy is based on matching the reduced cell of an unknown against a database of known materials represented by their respective standard reduced cells. The success of the method relies on the fact that the lattice or the lattice plus chemical information (e.g., element types) is highly characteristic of a material-like a fingerprint. Because of its intrinsic power, the procedure has many and diverse applications-in materials characterization, in nano-technology, in epitaxial growth, in materials design, etc. An especially fruitful role for the method is in the journal publication process as the quality of the scientific literature can be enhanced. The focus herein is on the major role that lattice matching can play in the prevention of inadvertent duplicate publications of the same structure and in the determination of key cross-references.

Algorithms for this purpose have been proposed, but none have been rigorously evaluated due to a lack of datasets. Accordingly, the Southern Great Plains 1999 Experiment (SGP99) was designed to provide C-band datasets for AMSR algorithm development and validation. Ground observations of soil moisture and related variables were collected in conjunction with aircraft measurements using a C-band radiometer similar to the AMSR sensor (6.92 GHz), the Polarimetric Scanning Radiometer with its C-band scanhead (PSR/C). The study region has been the focus of several previous remote sensing field experiments and contains vegetation conditions compatible with the expected capabilities of C-band for soil moisture retrieval. Flights were conducted under a wide range of soil moisture conditions, thus providing a robust dataset for validation. A significant issue found in data processing was the removal of anthropogenic radio-frequency interference. Several approaches to estimating the parameters of a single-channel soil moisture retrieval algorithm were used. PSR/C soil moisture images show spatial and temporal patterns consistent with meteorological and soil conditions, and the dynamic range of the PSR/C observations indicates that the AMSR instrument can provide useful soil moisture information.

Over the last decade, ballast water has been the focus of ongoing research into vectors of nonindigenous species (NIS) introductions. More recently, ballast sediment has also come under scrutiny as a possible source of anthropogenically introduced microorganisms. Transoceanic vessels, including tankers and bulk carriers, take on water to maintain their stability during transit. Most often, ballast water is obtained in shallow ports and sediment is incidentally pumped into holding tanks as well. Entrained in this sediment is a wide array of aquatic organisms, including benthic foraminifers, which may be discharged into distant ports when the vessels are subsequently deballasted. At least five NIS foraminiferal species have been reported worldwide, all in active shipping ports, and all are suspected of having been introduced by transoceanic vessels. In this study, we investigated the presence of foraminifers in ballast sediment samples obtained from three locations in the United States. Most of the vessels arriving in Prince William Sound, Alaska are tankers which originated in western U.S. ports, although a few arrive from overseas. The sediment from twelve of these ballasted vessels was sampled, nine of which contained foraminifers, including Ammonia beccarii, Rosalina globularis, Trochammina charlottensis, T. inflata, Miliammina fusca, Jadammina macrescens, Bulimina denudata, Elphidium, Globobulimina, Lagena, and Haplophragmoides. The NIS Trochammina hadai was also present in six samples, often in great abundance. Most of these species were also present in sediment obtained from a ballasted vessel from San Francisco Bay, and about 40% of the individuals were recovered alive. Vessels which have deballasted are referred to as NOBOB (No-Ballast-On-Board). Although most ballast water and sediment has been removed, residual amounts often remain behind. Sediment from eight of these vessels was sampled from the Great Lakes and numerous living individuals of Ammonia, Elphidium, and Textularia were recovered. Clearly, both ballasted and NOBOB vessels are a potential source of nonindigenous foraminiferal introductions.

The Climate Time Line Information Tool or CTL (http://www.ngdc.noaa.gov/paleo/ctl) has been proto-typed as a potential tool for conveying basic climate processes and their human dimension for diverse audiences. Using a powers of ten approach to temporal scaling, the CTL website was developed through a CIRES Innovative Research Grant by Mark McCaffrey and Dan Kowal at the National Geophysical Data Center. It has recently been evaluated for its potential as an interdisciplinary tool for conveying information about weather and climate processes, such as the diurnal, annual and orbital cycles, ENSO and other oscillations, as well as correlating climate change with human development over the past 100,000 years. Results of the evaluation, including issues of instructional design, will be discussed.

Unfortunately, the data for mineral phases of arsenic and their aqueous solubilities have been inadequately evaluated. This paper presents the results of a simultaneous, weighted, least-squares multiple regression on 77 thermochemical measurements of elemental arsenic, arsenic oxides, arsenic sulfides, and their aqueous hydrolysis products. These data were selected from a search of several hundred papers. To test the compatibility of the thermodynamic data with observations in nature, the resultant values for free energy, enthalpy, entropy, and heat capacity are used to derive mineral stability relationships for native arsenic, claudetite (As (sub 2) O (sub 3) ), arsenolite (As (sub 2) O (sub 3) ), orpiment (As (sub 2) S (sub 3) ), and realgar (AsS) using pepsilon -pH diagrams and known occurrences and transformations in the environment. Claudetite is the stable arsenic trioxide phase under standard state conditions and transforms to arsenolite below about -33 degrees C. Both claudetite and arsenolite form as weathering products of arsenopyrite, realgar, and native arsenic but arsenolite is the metastable phase at earth's surface conditions. At constant P (sub S2) , realgar and native arsenic become increasingly more stable than orpiment with increasing temperature. Realgar has two polymorphs, pararealgar and alacrinite, but thermodynamic data are not available for them. A new pepsilon -pH diagram shows the relative stabilities of As (sub 2) O (sub 5) , claudetite, orpiment, realgar and arsenic in the As-S-O system at 298.15 K and 1 atm. Native arsenic is only stable under very strong reducing conditions but is more stable at higher temperature. This critical evaluation of published data for selected arsenic species provides much more consistent data for geochemical modelling and the interpretation of geochemical processes involving arsenic in the environment.

We reconstructed the monsoon winds for the last 1,000 years using fossil Globigerina bulloides abundance in box cores from the Arabian Sea, and found that monsoon wind strength increased during the past 4 centuries, as the northern hemisphere warmed. We infer that the observed link between Eurasian warmth/ snow cover and the SW monsoon persists on the centennial scale. Alternately, the forcing implicated in the warming trend (volcanic aerosols, solar output, greenhouse gases) may directly affect the monsoon. Either interpretation is consistent with the hypothesis that the SW monsoon strength will increase during the coming century as greenhouse gas concentrations continue to rise and northern latitudes continue to warm.

The analyses performed determined that several of the thermal infrared bands of MODIS contributed significantly to detecting volcanic ash in the cases examined. Most, but not all, of these bands will be included in the next major upgrade to the Geostationary Operational Environmental Satellite (GOES) Imager scheduled for 2012. In Part II, MODIS data for the same volcanic cases examined in Part I (Popocatepetl near Mexico City and Cleveland in the Aleutian Islands) are used to simulate the impact of changes that will occur in spectral bands between current and near-term GOES imagery. The change from the 12.0-mu m band to a 13.3-mu m band on GOES-M (launched in 2001 and renamed GOES-12) was made to improve cloud-height determinations. However, when GOES-M becomes operational, the change in bands will have a potential negative impact on image products that are heavily utilized for volcanic ash detection. Image products generated from the three GOES infrared bands with the 13.3-mu m band substituted for the 12.0-mu m band indicate that volcanic ash can be detected but with diminished ability, especially for diffuse ash. For both day and night cases the increased contamination by clouds leads to increased chances of false ash detection.

We estimate the number of volcanoes known to occur along these arcs to be 693, with at least 206 (29%) being submarine. Less than 3% of arc length has been systematically surveyed for seafloor hydrothermal emissions. Submarine hydrothermal venting along these arcs therefore remains overwhelmingly undetected. Plumes and vent fluids from arc sites are chemically heterogeneous in nature and in some cases highly enriched compared to MOR sites. They include liquid- plus gas-rich to liquid-poor but gas-rich types. Evidence for a magmatic component in arc vent systems is given by the nature and concentrations of various gases and iron. The Kermadec arc extends for approximately 1,200 km northeastwards from New Zealand and forms the southern part of the approximately 2,500-km-long Tonga-Kermadec intra-oceanic arc system. At least 33 volcanoes occur along the Kermadec arc with all but one (Raoul Island) being submarine. The combined NZAPLUME I and II cruises of March 1999 and May 2002, respectively, have systematically surveyed approximately 840 km of the Kermadec arc including 26 major volcanoes and 8 smaller volcanic edifices. Ten of the volcanoes (38%) host active vent fields with Brothers and Healy each hosting two separate sites. In addition, both Curtis and Raoul islands host subaerial geothermal systems. Combined, this equates to a "vent field" every 70 km of arc length. However, our surveys show that venting is not distributed evenly along the Kermadec arc with "active" southern and northern sections hosting vent fields every approximately 35 km while a stretch of approximately 520 km of arc in between appears dormant (pending shore-based analyses such as helium isotope ratios) with respect to venting. If the frequency of venting for the presently surveyed part of the Kermadec arc is projected worldwide for all known submarine arc volcanoes, this equates to 78 hydrothermally active vent sites. Considering the number of sites still to be discovered, this makes submarine arcs a potentially a very rich source of hydrothermal fluids and minerals.

Many of the planning issues are social rather than biological, involving public use and its effects on Refuge resources and opportunities. Planners, managers, and stakeholders are finding themselves in the human ecotone. where two or more legal, social, and cultural edges intersect to produce an abundance and diversity of conflicts, challenges, and opportunities. Planning in the human ecotone requires collaboration, up-to-date information, and an adaptive process.

Notable contaminants that exhibit this behaviour include the polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and tributyltin (TBT). Thus, when these types of toxicants are released into aquatic systems, sediments can serve as a repository and as a pathway of exposure for fish, either through direct contact, or via contamination of prey and ingestion. Although sediment quality criteria have been developed by some agencies, generally these are based on tests with benthic invertebrates, and little guidance is available for either regulators or dischargers to determine what levels of contaminants in tissue or sediment pose little or no risk to fish. Accordingly, there is a need for specific guidance concerning the potential effects of contaminants on fishery resources. In this volume of Aquatic Conservation we present three papers which deal with assessing the levels of contaminants in tissue and sediment that may present risk of harm or injury to fish. Different approaches are used in each paper, primarily because each of them deals with different receptor species and a different toxicant or class of toxicants.

This paper examines the performance of this series of projections during their first five years. Using the census 2000 counts and estimated births, deaths, domestic migration, and international migration from administrative records, this paper examines the accuracy of projected total population and projected components of change for 50 states and the District of Columbia. The paper also examines the historical trend of projection accuracy and the geographic variation of projection accuracy by U.S. regions and subdivisions. A multiple regression analysis is used to analyze the relative impact of errors in the projected components of change, errors in state estimates, and 1990 census undercount on the accuracy of the latest state population projections. A discussion of the accuracy of national projections is also included. We found that the latest series of state population projections are more accurate than previous projections series. The projections continue to perform poorly in the West. The percent errors in domestic migration continue to be the highest among all projected components of change, followed by international migration. The projected births had the lowest average percent errors.

Quantifying errors in the estimation of basin mean precipitation AN - 19723612; 5565855 AB - Developments in analysis and modeling of continental water and energy balances are hindered by the limited availability and quality of observational data. The lack of information on error characteristics of basin water supply is an especially serious limitation. Here we describe the development and testing of methods for quantifying several errors in basin mean precipitation, both in the long-term mean and in the monthly and annual anomalies. To quantify errors in the long-term mean, two error indices are developed and tested with positive results. The first provides an estimate of the variance of the spatial sampling error of long-term basin mean precipitation obtained from a gauge network, in the absence of orographic effects; this estimate is obtained by use only of the gauge records. The second gives a simple estimate of the basin mean orographic bias as a function of the topographic structure of the basin and the locations of gauges therein. Neither index requires restrictive statistical assumptions (such as spatial homogeneity) about the precipitation process. Adjustments of precipitation for gauge bias and estimates of the adjustment errors are made by applying results of a previous study. Additionally, standard correlation-based methods are applied for the quantification of spatial sampling errors in the estimation of monthly and annual values of basin mean precipitation. These methods also perform well, as indicated by network subsampling tests in densely gauged basins. The methods are developed and applied with data for 175 large (median area of 51,000 km super(2)) river basins of the world for which contemporaneous, continuous (missing fewer than 2% of data values), long-term (median record length of 54 years) river discharge records are also available. Spatial coverage of the resulting river basin data set is greatest in the middle latitudes, though many basins are located in the tropics and the high latitudes, and the data set spans the major climatic and vegetation zones of the world. This new data set can be applied in diagnostic and theoretical studies of water balance of large basins and in the evaluation of performance of global models of land water balance.

Listed salmon species in the northwest United States are known to travel through urban areas in their migration from river to ocean. Species such as the chinook salmon (Oncorhynchus tshawytscha) often spend several weeks in these urban estuaries where they can be highly exposed to urban-related contaminants that reside in the sediments and accumulate in their prey species. The concern is that these contaminants are bioaccumulated to levels that may impact the ability of individual salmon to grow and mature normally. This paper provides a framework for determining the tissue and sediment concentrations of polychlorinated biphenyls (PCBs) that are likely protective against adverse effects in listed salmonid species. The relevant ecotoxicological literature was examined and 15 studies were selected that met the pre-established criteria outlined here. For each study, the lowest tissue concentration (residue) of total PCBs associated with a biological response was selected. The tissue concentration associated with the 10th percentile of these 15 studies was chosen to represent the residue effect threshold (RET) above which wild juvenile salmonids would be expected to exhibit adverse sublethal effects from accumulated PCBs. This value (2.4 mu g PCBs g super(-1) lipid) is expressed in terms of the lipid-normalized concentration because of the large effect lipid can have on the expressed toxicity and the substantial variability in lipid content observed in salmonids over their life cycle. A sediment concentration that is expected to produce the RET was then determined using the biota-sediment accumulation factor approach. The sediment effect threshold, which varies with the total organic carbon content in sediment, is the level above which adverse effects may be expected in juvenile salmonids due to accumulation of PCBs from environmental exposure. Bioaccumulation of PCBs was examined in one river system as a model for determining an appropriate bioaccumulation factor for wild juvenile chinook salmon. Evaluation of exposure to potentially deleterious concentrations of PCBs based on tissue residues is the preferred approach; however, the sediment effect threshold may also be used in cases where bioaccumulation has been characterized in an estuary. The threshold values presented here are intended as interim guidelines that should be modified as more data become available. Additionally, because of the uncertainty around many of the factors and assumptions that comprise the single threshold effect values, it is recommended that future studies be employed to help determine a range of acceptable values that would afford protection under various environmental and biological conditions.

This includes assessment of the impacts of exposure to toxic chemicals on fish and their critical habitat. This analysis was conducted to assist NMFS resource managers in determining when fish are exposed to potentially harmful concentrations of one of the most common environmental contaminants, polycyclic aromatic hydrocarbons (PAHs). Effects thresholds were estimated primarily through segmented regression of site-specific sediment PAH concentrations and associated disease prevalences in a resident fish species, English sole, Pleuronectes vetulus. The analyses and supporting data encompass several endpoints, including DNA damage, liver lesions, and impacts on growth and reproduction. In general, liver lesion prevalences, DNA adduct levels, and impacts on growth and reproduction were minimal at sediment PAH concentrations at or below 1000 ppb. Above 1000 ppb, there appears to be a substantial increase in the risk of contaminant-related injury to English sole.

A natural resource damage assessment (NRDA) has been initiated by three trustee agencies to determine the appropriate type and scale of restoration needed to restore natural resources injured by this contamination. Generally these resources are injured if: 1. the concentration of a hazardous substance exceeds government criteria or standards set to protect the use of the resource by people or wildlife (e.g., exceedance of water quality standards); or 2. the hazardous substance causes a measurable adverse change to the resource (e.g., causing cancer, reproductive, and other effects in biota). Preliminary reviews of available information indicate that: 1. the long-term exceedance of water quality criteria and standards constitutes an injury to water resources; 2. fish have been contaminated for over 25 years, and the resulting issuance of fishing bans and consumption advisories constitutes an injury to the public's use of this resource; and 3. average and maximum PCB concentrations recently measured in various habitats and biota raise concern that adverse effects may be occurring in Hudson River biota.

We cite similar sightings from Hawai'i and some additional behavioral observations (synchronized swimming, food sharing, regular association with flotsam), and suggest that rough-toothed dolphins may be specialized predators on large mahimahi.

Air and water temperatures were higher and precipitation was lower during in-phase or warm PDO/El Nino events than in other years. In contrast, in-phase or cool PDO/El Nino years were generally cooler and wetter than other years. Precipitation and East Creek discharge were positively related to the Southern Oscillation Index (SOI) and negatively related to the PDO index. Conversely, air and water temperatures were negatively related to the SOI and positively related to the PDO index. Differences in precipitation and air temperature were also evident at longer time scales when separated by PDO phase. Because of drier conditions during in-phase El Nino events, the flow of organic matter from East Creek to downstream portions of the channel network was lower compared to other years. This reduction has implications for downstream communities, as these subsidies provide a major source of energy for stream food webs. Therefore, short term and long term shifts in climate, discharge, and water temperature may have profound impacts on the ecology of Pacific Northwest (PNW) watersheds due to changes in a number of ecosystem processes such as altered flux of organic matter from headwater streams to larger rivers.

ER - TY - JOUR T1 - Microbial community interactions and population dynamics of an algicidal bacterium active against Karenia brevis (Dinophyceae) AN - 18850009; 5614203 AB - The population dynamics of Cytophaga strain 41-DBG2, a bacterium algicidal to the harmful algal bloom (HAB) dinoflagellate Karenia brevis, were investigated in laboratory experiments using fluorescent in-situ hybridization (FISH) and denaturing gradient gel electrophoresis (DGGE). Following its introduction into non-axenic K. brevis cultures at concentrations of 10 super(3) or 10 super(5) bacterial cells per milliliter, 41-DBG2 increased to 10 super(6) cells per milliliter before initiation of its algicidal activity. Such threshold concentrations were not achieved when starting algal cell numbers were relatively low (10 super(3) cells per milliliter), suggesting that the growth of this bacterium may require high levels of dissolved organic matter (DOM) excreted by the algae. It remains to be determined whether this threshold concentration is required to trigger an algicidal response by 41-DBG2 or, alternatively, is the point at which the bacterium accumulates to an effective killing concentration. The ambient microbial community associated with these algal cultures, as determined by DGGE profiles, did not change until after K. brevis cells were in the process of lysing, indicating a response to the rapid input of algal-derived organic matter. Resistance to algicidal attack exhibited by several K. brevis clones was found to result from the inhibition of 41- DBG2 growth in the presence of currently unculturable bacteria associated with those clones. These bacteria apparently prevented 41-DBG2 from reaching the threshold concentration required for initiation of algicidal activity. Remarkably, resistance and susceptibility to the algicidal activity of 41-DBG2 could be transferred between K. brevis clones with the exchange of their respective unattached bacterial communities, which included several dominant phylotypes belonging to the alpha -proteobacteria, gamma -proteobacteria, and Cytophaga-Flavobacterium-Bacteroides (CFB) groups. We hypothesize that CFB bacteria may be successfully competing with 41-DBG2 (also a member of the CFB) for nutrients, thereby inhibiting growth of the latter and indirectly providing resistance against algicidal attack. We conclude that if algicidal bacteria play a significant role in regulating HAB dynamics, as some authors have inferred, bacterial community interactions are crucial factors that must be taken into consideration in future studies.

In the years following the spill, Spartina alterniflora seedlings were planted at a number of the oil damaged sites and successfully reestablished at these sites. In 1996, the National Marine Fisheries Service began a study to compare the benthic invertebrate assemblages at the reestablished S. alterniflora marshes to those at nearby existing marshes in the Arthur Kill. Oligochaetes, nematodes, and the small tube-building polychaete, Manayunkia aestuarina were the dominant taxa in the study. Significant differences were found in the abundances of all invertebrate individuals, oligochaetes, and nematodes between the September and May sampling times but not between reestablished and existing marshes. Although benthic invertebrate community structure was similar at reestablished and existing marshes three to four years after planting, the functional similarity of these marshes was not assessed in this study.

Water and energy supply control of their interannual variability AN - 18669248; 5565856 AB - Controls on interannual variations in water and energy balances of large river basins (10,000 km super(2) and greater) are evaluated in the framework of the semiempirical relation E/P = [1 + (R/P) super(-v)] super(-1/v) in which and E, P, and R are basin mean values of annual evaporation, precipitation, and surface net radiation, respectively, expressed as equivalent evaporative water flux, overbars denote long-term means, and v is a parameter. Precipitation is interpolated from gauges; evaporation is taken as the difference between precipitation and runoff, with the latter determined from basin discharge measurements and a simple storage-delay model; and radiation is based on a recent analysis in which 8 years of satellite observations were assimilated into radiative transfer models. Objective estimates of precipitation errors are considered; results suggest that past estimates of v may have been biased by systematic errors in estimates of precipitation. Under the assumption that the semiempirical relation applies also to annual values, long-term mean observations are sufficient to predict the sensitivity of annual runoff to fluctuations in precipitation or net radiation. Additionally, an apparent sensitivity of runoff to precipitation can be inferred from the observations by linear regression. This apparent sensitivity is generally in good agreement with the predicted sensitivity. In particular, the apparent sensitivity increases with decreasing basin R/P; however, slightly excessive apparent sensitivity (relative to the prediction) is found in humid basins of the middle latitudes. This finding suggests a negative correlation between precipitation and net radiation: the increase in runoff caused by a positive precipitation anomaly is amplified by an accompanying decrease in surface net radiation, possibly induced by increased cloud cover. The inferred sensitivity of radiation (water flux equivalent) to precipitation is on the order of -0.1. Such a value is supported by independent direct analysis of annual precipitation and radiation data. The fraction of interannual variance in runoff explained by the annual precipitation anomaly (including any correlative influence of net radiation) varies systematically with climatic aridity, approaching unity in humid basins and falling to 40-80% in very arid basins. We conclude that the influence of seasonality of the precipitation anomaly on annual runoff is negligible under humid conditions, though it may be significant under arid conditions.

Development and Implementation AN - 18626450; 5533610 AB - The Community Multiscale Air Quality (CMAQ) modeling system is adapted to simulate the regional transport and fate of atrazine, one of the most widely used herbicides in the United States. Model chemistry and deposition are modified, and a gas-to-particle partitioning algorithm is added to accommodate semivolatile behavior. The partitioning algorithm depends on humidity, temperature, and particulate matter concentration and composition. Results indicate that gaseous atrazine will usually dominate warm season atmospheric concentrations, but particulate form can surpass gas forms when atmospheric humidity is high (>70%) and less-acidic (pH > 2.5) aqueous aerosol component is present. Implementation of the modified CMAQ for atrazine is illustrated, and, within the limits of our current understanding, preliminary transport and fate patterns appear to be reasonable. This research represents one of the first attempts to include a gas-to-particulate matter partitioning mechanism in an Eulerian grid-model.

AN - 18613277; 5515589 AB - Residence patterns of inshore bottlenose dolphins (Tursiops truncatus) in the Stono River estuary, Charleston County, South Carolina were investigated as part of a larger effort to better understand stock structure of these dolphins along the east coast of the United States. Eighty-seven small-boat surveys for bottlenose dolphins were conducted from October 1994 through January 1996. Dolphins were sighted during all surveys. Approximately 304 h were spent surveying the study area; 64% (n = 196 h) of this time was spent observing and videotaping dolphins. A catalog, containing 112 individually identified dolphins was compiled. Thirty-two percent (n = 36) of identified dolphins were sighted once, while 28% (n = 31) were sighted five or more times. Nineteen percent (n = 21) of identified dolphins were determined to be year-round residents; eight percent (n = 9) seasonal residents. The majority (64%, n = 72) of identified dolphins were sighted in the study area during a single season or in two consecutive seasons and were classified as transients. This study documents the northernmost known site of a resident bottlenose dolphin community on the east coast of the United States, suggesting a complex bottlenose dolphin stock structure.

Two approaches for determining adverse sediment concentrations due to tributyltin (TBT) contamination are presented here. The first is the equilibrium partitioning (EqP) approach, which relies on a sediment-water partition coefficient and toxicological data for water exposures. The EqP approach utilizes the large water quality database that has been generated over the last two decades for TBT and provides strong evidence for adverse effects at low exposure concentrations. The second approach involves determination of a TBT tissue residue that is considered harmful for most species, which is then used to predict the sediment concentration that would likely produce this adverse tissue concentration. Both approaches are presented here because they generally support each other but based on the information presented below, and the inherent difficulty in measuring porewater concentrations, the tissue residue approach is the recommended method for determining adverse sediment concentrations. Using this analysis, the protective sediment concentration for TBT proposed here is 6000 ng g super(-1) organic carbon. Direct effects are not expected on salmonids at this sediment concentration because of their relatively short residence time in the estuary, general lack of interaction with sediment, and relatively high metabolic capacity. This concentration may ensure adequate abundance of salmonid prey species; however, it may not be low enough for the protection of sensitive benthic species.

During late July-August of 1985-1987, 1989, and 1991, 107 samples were collected from off the Pacific coast of Honshu. An additional 20 samples were collected from whales taken in the southern Sea of Okhotsk during late August-September of 1988 and 1989. Prey identification using fish otoliths and cephalopod beaks revealed the whales fed primarily on deep-water gadiform fishes and cephalopods in both regions. Prey species diversity and the percentage of cephalopods and fish differed between the two regions. Off the Pacific coast of Honshu the whales fed primarily on benthopelagic fishes (81.8%) and only 18.0% on cephalopods. Eight species of fish representing two families, the codlings (Moridae) and the grenadiers (Macrouridae), collectively made up 81.3% of the total. Thirty species of cephalopods representing 14 families made up 12.7%. In the southern Sea of Okhotsk, cephalopods accounted for 87.1% of stomach contents. The families Gonatidae and Cranchiidae were the predominant cephalopod prey, accounting for 86.7% of the diet. Gadiform fish accounted for only 12.9% of the diet. Longfin codling, Laemonema longipes, was the dominant fish prey in both regions. Depth distribution of the two commonly consumed fish off the Pacific coast of.

The Mg(II)-dependent enzyme converts 4-diphosphocytidyl-2C-methyl-D-erythritol 2-phosphate into the cyclic compound 2C-methyl-D-erythritol 2,4-cyclodiphosphate, and CMP. We report here the crystal structure of the enzyme from Haemophilus influenzae (HI0671). The protein was selected as a Structural Genomics target (http://www.s2f.umd.edu), focusing on proteins of unknown function, before the functional annotation of the sequence. The trimeric association and overall fold of the protein is the same as that of the E. coli enzyme, consistent with their high amino acid sequence identity (77%). However, a large polypeptide segment adopts an entirely different conformation, such that a histidine residue, invariant in 45 of 50 known sequences (conservatively replaced by asparagine in the remaining five sequences), coordinates to Zn(II). We propose that enzyme activity may be regulated by a conformational transition of this structural unit.

These data were collected via HF radio from automatic weather stations operated by the Australian Institute of Marine Science at Myrmidon and Agincourt Reefs in the central Great Barrier Reef. At Myrmidon Reef, CREWS was useful in "predicting" coral during the end of January and early February 2000. This prediction was verified in the field with observations of low level bleaching for a few species of Acropora bleaching (especially Acropora gemmifera and A. digitifera) on the reef flat at Myrmidon Reef. In February 2000, alerts were produced and sent for Agincourt Reef, 330 km north of Myrmidon Reef, but field observations showed that bleaching did not occur. These results suggest that CREWS may be fine-tuned to predict bleaching in thermally sensitive species or genera at individual locations.

This system is particularly relevant because multiple environmental stressors may contribute to bleaching, one mechanism for coral mortality worldwide. In laboratory studies, diagnostic parameters distinguished the separate and combined effects of heat and light on a star coral (Montastraea faveolata) and its symbiont (zooxanthellae), and provided evidence that oxidative stress plays a central role in bleaching. We also used this new biotechnology to characterize bacteria-induced bleaching in the ivory tree coral (Oculina varicosa). Our data suggest that bacteria-induced coral bleaching may involve non-oxidative stress mechanisms. Thus, the molecular diagnostic system enabled us to (1) diagnose whether corals were physiologically stressed, (2) potentially discriminate between mechanisms involved in coral bleaching, and (3) provide evidence that chloroplast small heat-shock proteins protect against coral bleaching.

Hotspots are anomalies above a satellite-derived climatological Maximum Monthly Mean (MMM) SST. An increase to 1 degree C above the MMM SST during summer is a general threshold for inducing coral bleaching. 50 km HotSpot resolution predicted bleaching over broad areas during a major climatic event (1998 ENSO); however, regional and reef-scale (meters to tens of kilometers) warming events may induce coral bleaching. To test reef-scale monitoring, a 9 km retrospective (1998) HotSpot mapping study used NASA/JPL AVHRR Oceans Pathfinder Best SST data. Pathfinder SSTs accurately reproduced in situ temperatures, and were used to create a 9 km MMM threshold climatology for high-resolution HotSpot mapping. Warmer 9 km climatology values throughout the tropics generally reduced anomaly levels from the 50 km product, suggesting that coral bleaching may be triggered by minimal thermal stress.

Despite lip-service paid to "monitoring" in most restoration plans, the rigorous evaluation of these efforts has been, often, lacking completely and the declaration of success is often based on the most rudimentary criteria (stability of artificial structures or survival of x% of coral transplants). In very few cases, restoration projects have been designed to test the effectiveness of different restoration approaches (e.g. structure designs) in enhancing the biological performance (e.g. recruitment, growth, disease susceptibility) of key organisms and, in even fewer cases, in enhancing community function. However, these studies demonstrate the power of an adaptive management approach to restoration; that is, rigorously evaluating the ecological performance of alternative restoration approaches in order to do better in the future. Specific evaluative examples from other shallow coastal systems suggest that ecological success can be enhanced by simple and inexpensive restoration approaches. If coral reef restoration is to advance beyond its current "build it and they will come" paradigm, an experimental approach and the evaluation and implementation of ecological restoration measures built upon our understanding of reef community process and function must be pursued.

In recent decades both species have declined from white-band disease and other factors. To increase awareness about their decline, the National Marine Fisheries Service in June 1999 identified A. palmata and A. cervicornis as candidate species for the United States Endangered Species Act (ESA). Candidate status does not add legal protection, but is designed to promote efforts to obtain reliable information on the species and to encourage voluntary conservation strategies for the protection of remaining populations. Application of the ESA to marine invertebrates presents several challenges. While distinct vertebrate populations can be listed, a marine invertebrate must be threatened throughout its range. Both Acropora spp. are widespread, however a survey of available information revealed gaps that prevent a synoptic overview of their status. Furthermore, measures of rarity have been developed for individuals, and may not be applicable to clonal organisms that rely on asexual fragmentation as a primary mode of propagation. An ESA listing requires implementation of a recovery plan and action by Federal agencies to conduct conservation programs, and to promote research, restoration and protection for these species, thereby benefiting associated coral reef organisms and the ecosystems upon which they depend.

Research flights were conducted primarily in the Northern Hemisphere to the west and southwest (i.e., downwind) of the Indian subcontinent, although several flights crossed the Intertropical Convergence Zone (ITCZ) into the much cleaner Southern Hemisphere air. The optical and hygroscopic properties of submicrometer aerosols were measured most of the time, although measurements on aerosol particles smaller than 3 mu m have also been reported. Low-altitude (0-1 km altitude) measurements of the submicrometer aerosol light scattering coefficient ( sigma sub(sp), adjusted to standard temperature and pressure) in the INDOEX pollution aerosol showed a median value of 53 Mm super(-1), which is a factor of 2-5 higher than the median values during polluted periods at remote North American marine/coastal sites but similar to those observed at rural U.S. stations during high-aerosol periods. Submicrometer light absorption coefficients were even higher compared with the North American measurements, at 4-23 times those median values. Single-scattering albedo ( omega sub(0)) measurements showed that the Indian Ocean pollution aerosol was highly absorbing, with mean values at ambient relative humidity between 0.84 and 0.87 for low-altitude flight segments conducted in the Northern Hemisphere. The aerosol hygroscopic growth factor, defined as f(RH) = sigma sub(sp (RH=85%))/ sigma sub(sp (RH=40%)), averaged 1.58 for flight segments below 1 km altitude and north of 5 degree N. This is a substantially lower f(RH) than typically observed at midcontinent Northern Hemisphere sites, although it is nearly identical to that observed at these sites when aerosols were influenced by agricultural burning or dust episodes in the surrounding area. Aerosol optical properties over the Indian Ocean also showed significant variability in both the horizontal and the vertical on very short spatial and temporal scales. Cloud-free level flight segments of only 10-30-min duration showed a mean variability (standard deviation/mean) in the 1-min average ambient aerosol extinction coefficient of 18% and a mean difference between the lowest and the highest segment extinction measurement of 39%. Vertical profiles conducted over the Northern Hemisphere Indian Ocean showed two major types of profiles. One type showed nearly constant to decreasing aerosol scattering with increasing altitude, while the other type displayed elevated aerosol layers that did not appear to be associated with boundary layer aerosols and were occasionally separated from them by relatively clear layers. These intense elevated layers, which were present in 52% of all profiles, often showed scattering coefficients several times as large as those measured near the surface. A change in synoptic-scale circulation patterns halfway through the project may have caused more of these elevated decoupled layers to be observed during the second half of the IFP and may have caused them to be observed at higher altitudes.

In order to extract the forced response from natural, internal variability, the difference between the mean of an eight-member ensemble of numerical experiments and a control experiment are used for the present analysis. The global mean surface air temperature of the coupled model increases by about 2.3 degree C above the preindustrial level by the middle of the 21st century. Accompanying the warming, the global mean rates of both precipitation and evaporation increase by 5.2%, yielding the average increase in the rate of runoff by approximately 7.3%. The increase in the rate of runoff simulated by the model is particularly large in high northern latitudes, where the runoff from some rivers such as the Mackenzie and Ob' may increase by as much as 20%. Runoff from many European rivers increases by more than 20%. Runoff also increases substantially in some tropical rivers such as the Amazon and Ganges. However, the percentage changes in simulated runoff from many other tropical rivers and middle latitude rivers are smaller with both positive and negative signs. In middle and high latitudes in the Northern Hemisphere, soil moisture tends to decrease in summer, whereas it increases in winter. However, in many semi-arid regions in subtropical and middle latitudes, soil moisture is reduced during most of a year. These semi-arid regions include the southwestern part of North America, the northeastern part of China in the Northern Hemisphere, and the region in the vicinity of the Kalahari Desert and southern part of Australia in the Southern Hemisphere. Since a semi-arid region usually surrounds a desert, the reduction of soil moisture in such a region often results in the expansion of the desert. Soil moisture is also reduced during the dry season in many semi-arid regions. For example, it is reduced in the savannahs of Africa and South America during winter and early spring in the Southern Hemisphere. In the Northern Hemisphere, it is reduced at the Mediterranean coast of Europe in summer.

Here we provide a rationale for using 20-30% minimum no-take protection to conserve coral reef ecosystems. Support comes from reproductive theory, knowledge about the vulnerability of reef species to exploitation, analysis of fishery failures, and empirical and modeling studies of reserves. Other support comes from applying principles of precautionary management and a need for having minimally disturbed reference sites. Reserves alone will not protect all species and must be used in addition to other fishery and resource management measures to obtain high sustainable fishery production. Ultimately, human activities must be within sustainable limits of coral reef ecosystems.

A habitat-based assessment strategy is proposed that integrates a comprehensive submersible survey with new high-resolution sonar imagery of the seafloor. This approach was applied to data sets from Heceta Bank, OR, using 42 submersible dives from 1988-90 and a 1998 multibeam sonar survey. Collection and characteristics of each data type are described. Submersible data are used to extrapolate fish abundance within uniform patches over broad areas of the bank based on habitat classification derived from the sonar imagery. Correlation with major boundaries on the backscatter and topographic boundaries on the imagery was good. Preliminary stock assessments for several demersal fish species obtained with this method are reported. This habitat-based approach will enable researchers to characterize marine communities over large seafloor areas.

The effects of three levels of experimental harvesting (current size-selective harvest, monthly complete harvest, and no harvest) on red sea urchins in a marine reserve in San Juan Channel, northern Washington, were studied. Density and size distribution changes were observed. Existing populations are predominantly older, large individuals, with juveniles comprising <1% of the population. Lower and upper size limits would protect 5% and 45% of the population, respectively. Complete harvests reduced urchin densities by 95%. Size selective harvests reduced sea urchin densities by 67% the first year and 47% the second year, and the size distribution was altered so that legal-size urchins were less abundant. Recolonization also was monitored for each harvest level. Managers should reconsider marine harvest refuges and existing size limits to improve the sustainability of the sea urchin fishery.

A semiquantitative study to examine this sustainability was conducted, with respect to susceptibility to capture and mortality due to trawling, and the ability of populations to recover after depletion. Biological and ecological criteria were used to rank species with respect to these characteristics. Estimates of catch rates and within-net survival of various elasmobranch species were derived. For most species, more than half the individuals in the bycatch were immature. For all species combined, 66% of the individuals in the bycatch died in the net. Four elasmobranch species least likely to be sustainable under current bycatch conditions are identified; these are bottom-associated batoids that are highly susceptible to capture in shrimp trawls, and have a poor recovery capacity.

Bycatch data were collected by observers at sea from June 1997-May 1999. Billfish bycatch by purse seiners generally is very low, and is less than 10% of the total billfish catches currently reported. Simulation modeling showed that the temporary moratorium on fishing with fish aggregating devices (FADs), required in the European purse-seine fishery in this region, resulted in lower incidental catches of marlins, but increased bycatch of sailfishes. Indices for evaluating marine fish conservation status are difficult to devise. An ecosystem approach that incorporates biological and socioeconomic criteria is essential for large pelagic resource management.

For many parameters, satellite measurements are the only means of obtaining this information, particularly over the oceans and sparsely-populated land areas. For example, multi-spectral measurements from both geostationary and polar-orbiting satellites are key components of the Global Precipitation Climatology Project (GPCP), which has measured global rainfall for over 20 years. In addition, the longstanding National Oceanic and Atmospheric Administration (NOAA)-based Northern Hemispheric snow cover climatology has relied almost solely on satellite observations that are interpreted by satellite analysts.

AN - 72075710; 12220190 AB - We recently introduced a new substrate rescue tool for investigating enzymatic base flipping by uracil DNA glycosylase (UDG) in which a bulky pyrene nucleotide wedge (Y) was placed opposite a uracil in duplex DNA (i.e., a U/Y pair), thereby preorganizing the target base in an extrahelical conformation [Jiang, Y. L., et al. (2001) J. Biol. Chem. 276, 42347-54]. The pyrene wedge completely rescued the large catalytic defects resulting from removal of the natural Leu191 wedge, presumably mimicking the pushing and plugging function of this group. Here we employ the pyrene rescue method in combination with transient kinetic approaches to assess the functional roles of six conserved enzymatic groups of UDG that have been implicated in the "pinch, push, plug, and pull" base-flipping mechanism (see the preceding paper in this issue). We find that a U/Y base pair increases the apparent second-order rate constant for damaged site recognition by L191G pushing mutation by 45-fold as compared to a U/A pair, thereby fully rescuing the kinetic effects of the mutation. Remarkably, the U/Y pair also allows L191G to proceed through the conformational docking step that is severely comprised with the normal U/A substrate, and allows the active site of UDG to clamp around the extrahelical base. Thus, pyrene also fulfills the plugging role of the Leu191 side chain. Preorganization of uracil in an extrahelical conformation by pyrene allows diffusion-controlled damage recognition by all of these base-flipping mutants, and allows the UDG conformational change to proceed as rapidly as the rate of uracil flipping with the natural U/A base pair. Thus, the pyrene wedge substrate allows UDG to recognize uracil by a lock-and-key mechanism, rather than the natural induced-fit mechanism. Unnatural pyrene base pairs may provide a general strategy to promote site-specific targeting of other enzymes that recognize extrahelical bases.

These copepods were first exposed to low doses ( similar to 2 mu g of total PAC/L) of the water-soluble fraction of weathered Alaska North Slope crude oil for 24 h and subsequently to low or high levels of natural sunlight. Responses included mortality, impairment of swimming ability, and discoloration of lipid sacs. There was 80-100% mortality and morbidity of C. marshallae exposed to UV and oil as compared to less than 10% effect in oil-only or UV-only treatments. In M. okhotensis, 100% mortality occurred in the UV and oil treatment, 43% mortality and 27% morbidity in the UV-only treatment, and less than 5% effect in the oil-only treatment. Bioaccumulation factors were similar to 8000 for C. marshallae and similar to 2000 for M. okhotensis. The interaction of the effect of PAC and UV radiation was highly significant (P < 0.005) in both experiments.

Spring collections from 2 consecutive years of El Nino conditions, 1997 and 1998, 1 year of La Nina conditions, 1999, and 1 non-anomalous year, 1995, were examined. During spring of 1997, the first year of the El Nino event, early-juvenile hake appeared to compensate for anomalous ocean conditions by ingesting a wider variety of zooplankton taxa and sizes. Continuation of El Nino conditions through spring 1998 appeared to have a strong impact on the 1998 year class. Very low levels of macrozooplankton biomass in February 1998 resulted in poor growth and reduced survival of hake from early spawns.

AN - 71874084; 12088636 AB - Grass shrimp (Palaemonetes pugio) populations exposed to anthropogenic contaminant sources in South Carolina (SC) have reduced densities when compared with populations at SC-reference sites. This laboratory study examined the effects of a commonly used agricultural insecticide, endosulfan, on grass shrimp reproduction. Reproductively active grass shrimp were chronically exposed to sublethal concentrations of endosulfan (200 or 400 ng/l) for 43 days. The cumulative number of females that became gravid and the rate at which they became gravid were measured. Endosulfan exposure reduced the cumulative number of gravid females by 31% in the 200 ng/l exposure and 39% in the 400 ng/l exposure. The first appearance of gravid females in the population was significantly delayed in treated populations compared with the control treatment in a dose dependent manner. Clutch size in these gravid females was not significantly different among the treatments. Additionally, there was no difference in the onset of reproduction in the treated populations. These results implicate a population reduction due to a decrease in the overall number of females becoming gravid in a population over time, not a reduction in clutch size per individual.

Aqueous solutions of perchlorate (at a concentration of 100 mu g/L of ClO super(-) sub(4) by "spiking" with KClO sub(4)) were fed to the membrane test apparatus. Solutions contained only perchlorate, or an additional salt (KCl, K sub(2)SO sub(4), or CaCl sub(2)) at overall ionic strengths of 30, 60, or 115 mS/cm, and pH adjusted to 4, 6, 8, or 10. The data were modeled by application of a non-equilibrium thermodynamic model. The model has five parameters: the molecular transport coefficient ( omega ), osmotic pressure gradient ( Delta capital pi ), molecular reflection coefficient ( sigma ), the average bulk fluid interfacial concentration between the feed and permeate side (C sub(avg)), and the solvent flux (J sub(v)). These parameters were determined by independent measurements (and calculation with minimum assumptions.) For example, the molecular transport coefficient ( sigma ) was obtained by diffusion cell measurements under varying pH and conductivity conditions -- generally it decreased with increasing pH and increased with conductivity for the membranes in our study. Measured and predicted perchlorate transport was in good agreement. Overall, the results indicate that, in a pure component system, target ions (in this case ClO super(-) sub(4)) can be excluded from (negatively) charged membranes with pores large with respect to the size of the ion, but this rejection capability is quickly lost in the presence of a sufficient amount of other ions that can screen the apparent electrostatic force field. As intuitively expected, the perchlorate flux is governed by convection in large pore membranes.

Intraguild predation can dampen or even reverse the top-down effects predicted by food chain theory. The degree of self-limitation among the intraguild prey is a key factor in determining the direction and strength of the top-down response. Intraguild predation and self-limiting factors can also substantially alter the bottom-up effects of enrichment. These results can help explain the disparate results of trophic cascade experiments in lakes, where cascades are usually seen when large Daphnia are the primary herbivores, but not when smaller-bodied herbivores are dominant. Top-down manipulations should cascade at least modestly to phytoplankton in those lakes whose food web can be reasonably approximated by a chain (typically, those where Daphnia is the dominant herbivore), as predicted by food chain theory. On the other hand, smaller-bodied zooplankton are often preyed upon heavily by invertebrate predators as well as by planktivorous fish, thereby introducing elements of intraguild predation into these food webs. In this case, conventional food chain theory is likely to give incorrect predictions. Very large cascade effects may be due primarily to regime shifts between intraguild predation-dominated food webs and those that more resemble food chains, rather than due to the simple food chain cascade usually considered.

Recent studies used single crystal ceramic whiskers to reinforce dental composites. The aim of this study was to investigate the effects of thermal cycling on whisker-reinforced composites. It was hypothesized that the whisker composites would not show a reduction in mechanical properties or the breakdown of whisker-resin interface after thermal cycling. Silicon carbide whiskers were mixed with silica particles, thermally fused, then silanized and incorporated into resin to make flexural specimens. The filler mass fraction ranged from 0% to 70%. The specimens were thermal cycled in 5 C and 60 C water baths, and then fractured in three-point bending to measure strength. Nano-indentation was used to measure modulus and hardness. No significant loss in composite strength, modulus and hardness was found after 10 super(5) thermal cycles (family confidence coefficient=0.95; Tukey's multiple comparison test). The strength of whisker composite increased with filler level up to 60%, then plateaued when filler level was further increased to 70%; the modulus and hardness increased monotonically with filler level. The strength and modulus of whisker composite at 70% filler level were significantly higher than the non-whisker controls both before and after thermal cycling. SEM revealed no separation at the whisker-matrix interfaces, and observed resin remnants on the pulled-out whiskers, indicating strong whisker-resin bonding even after 10 super(5) thermal cycles. In conclusion, novel dental resin composites containing silica-fused whiskers possessed superior strength and modulus compared to non-whisker composites both before and after thermal cycling. The whisker-resin bonding appeared to be resistant to thermal cycling in water, so that no loss in composite strength or stiffness occurred after prolonged thermal cycling.

Current Population Reports. AN - 62230532; ED469530 AB - This report presents poverty data from the 2000, 2001, and 2002 Current Population Survey Annual Demographic Supplements, which provide information for caledar years 1999, 2000, and 2001. The poverty rate changed from 11.3 percent in 2000 to 11.7 percent in 2001. People below the poverty thresholds numbered 31.6 million in 2000 and 32.9 million in 2001. At 16.3 percent, the poverty rate for children remained higher than that of other age groups. It did not change during 2000-01. For people age 18-64 years, the poverty rate rose from 9.6 percent to 10.1 percent between 2000-01. There were 6.4 million poor families in 2000 and 6.8 million in 2001. For non-Hispanic whites, the poverty rate and the number who were poor rose between 2000 and 2001. Poverty rates for blacks, Hispanics, and Asians and Pacific Islanders did not change between 2000-01. The poverty rate in the south increased from 12.8 to 13.5 percent between 2000-01. The poverty rate for people living in the suburbs rose from 2.8 percent in 2000 to 8.2 percent in 2001. How poverty was measured affected the perception of who was poor. Four of six experimental poverty measures showed an increase in the poverty rate from 2000-01. Two appendices present time series poverty estimates by selected characteristics, 1959 to 2001 and sample expansion and introduction of Census 2000-based population controls.

Commercial amosite and crocidolite always exhibit uniaxial-like optical properties including parallel extinction and two principal indices of refraction. Fibrous members of the actinolite series, however, exhibit a range in optical properties from normal to anomalous. The types of anomalous optical properties that can be displayed by asbestiform members of the actinolite series are described based on a study of twelve samples. One sample displays uniaxial-like properties, nine display partial development of uniaxial-like properties, and two contain fibers with both orthorhombic and monoclinic optical properties. "Byssolitic" samples of the actinolite series, a fibrous non-asbesti-form habit, contain fibers that do not go to extinction in sections on or near (010), probably as a result of {100} twinning. Although anomalous optical properties may confound the identification of fibrous amphiboles, in most cases the refractive indices are predictable and can be used for identification. Because of the range in optical properties, especially extinction angle, reliance solely on parallel extinction to distinguish asbestos from non-asbestiform varieties is not recommended. The fibrillar structure, however, remains the hallmark of the asbestiform habit.

Discrete volcanic centers marked by large volcanic constructions and accompanying short wavelength mantle Bouguer anomaly (MBA) lows generally resemble those of the Gakkel Ridge and the easternmost Southwest Indian Ridge. These magmatically robust segment centers are regularly spaced about 85-100 km apart along the ridge, and are characterized by accumulated hummocky terrain, high relief, off-axis seamount chains and significant MBA lows. We suggest that these eruptive centers correspond to areas of enhanced magma flux, and that their spacing reflects the geometry of underlying mantle upwelling cells. The large-scale thermal structure of the mantle primarily controls discrete and focused magmatism, and the relatively wide spacing of these segments may reflect cool mantle beneath the ridge. Segment centers along the southern Knipovich Ridge are characterized by lower relief and smaller MBA anomalies than along the northern section of the ridge. This suggests that ridge obliquity is a secondary control on ridge construction on the Knipovich Ridge, as the obliquity changes from 35 degrees to 49 degrees from north to south, respectively, while spreading rate and axial depth remain approximately constant. The increased obliquity may contribute to decreased effective spreading rates, lower upwelling magma velocity and melt formation, and limited horizontal dike propagation near the surface. We also identify small, magmatically weaker segments with low relief, little or no MBA anomaly, and no off-axis expression. We suggest that these segments are either fed by lateral melt migration from adjacent magmatically stronger segments or represent smaller, discrete mantle upwelling centers with short-lived melt supply.

Using the SPME-GC-MIP-AES method, enrichment factors for methylmercury and butyltin compounds of 50-100 were achieved, as compared to the typical hexane extraction, and measurements in marine tissue and sediment matrixes were possible at 1-2 mu g/kg (methylmercury) and 10-100 ng/kg (butyltins). The SPME-GC-MIP-AES method was validated using several marine sediment and tissue matrix certified reference materials (CRMs) with certified values for methylmercury and butyltin compounds. The SPME-GC-MIP-AES method was used to measure methylmercury in four marine tissue CRMs ranging from oyster tissue at 13.0+ or -1.0 mu g/kg to fish tissue at 397+ or -13 g/kg (as Hg dry mass). Results from the SPME-GC-MIP-AES method were used in conjunction with results from other techniques to assign certified values for methylmercury in oyster, mussel, and fish tissue CRMs. Mono-, di-, and tributyltin were measured in three sediment CRMs at concentration levels of (0.08+ or -0.03)-(0.35+ or -0.05) mg/kg (as Sn dry mass).

An important part of the prevention of such a failure is maintaining the ability to control the release of water after the earthquake. For most earthen dams, and some concrete dams, the release of water is controlled through a reinforced concrete intake tower. The functional survival of such towers has been the main concern of a multi-year research effort sponsored by the U.S. Army Corps of Engineers (USACE). Most intake towers in the current USACE inventory are lightly reinforced. The functional survival of such lightly reinforced structures is thus the main concern of this research effort. The ultimate objective of this research work is the development of analysis procedures for seismic evaluation of these structures. This paper presents some of the results of this effort.

For this purpose, data from five different buildings are analyzed using only spectral analyses techniques. Additional data such as free-field records in close proximity to the buildings and site characterization data are also used to estimate site frequencies and thereby to provide convincing evidence and confirmation of the site frequencies inferred from the building records. Furthermore, simple code-formula is used to calculate site frequencies and compare them with the identified site frequencies from records. Results show that the simple procedure is effective in identification of site frequencies and provides relatively reliable estimates of site frequencies when compared with other methods. Therefore the simple procedure for estimating site frequencies using earthquake records can be useful in adding to the data base of site frequencies. Such data bases can be used to better estimate site frequencies of those sites with similar geological structures. JF - NIST Special Publication AU - Celebi, Mehmet A2 - Cauffman, Stephen A.

For larger motions they are based on theoretical and laboratory results. The Northridge earthquake of 17 January 1994 and other recent earthquakes have provided significant new sets of empirical data up to 0.5 g. These data together with recent site characterizations based on shear-wave velocity measurements provide empirical estimates of the site coefficients at base accelerations up to 0.5 g for Site Classes C and D. These empirical estimates of F (sub a) and F (sub v) as well as their decrease with increasing base acceleration level are consistent at the 95 percent confidence level with those in present building code provisions, with the exception of estimates for F (sub a) at levels of 0.1 and 0.2 g, which are less than the than the lower confidence bound by amounts up to 13 percent. The site-coefficient estimates are consistent at the 95 percent confidence level with those of several other investigators for base accelerations greater than 0.3 g. These consistencies and present code procedures indicate that changes in the site coefficients are not warranted. JF - NIST Special Publication AU - Borcherdt, Roger D A2 - Cauffman, Stephen A.

For this test series, twenty-six, level ground models with either a dense layer over a loose layer or homogeneous profile were tested in an equivalent-shear-beam box. Some models were subjected to sequential earthquakes, and some models were overconsolidated, to observe stress-history effects on pore pressure development.

It has emphasized the importance of earthquake engineering research into why and how structures collapse in real earthquake conditions. Considering the lessons learnt from recent earthquake disasters, NIED plan to construct a "3-D Full-Scale Earthquake Testing Facility ("E-Defense" is the nickname of this facility)", which will be able to simulate the processes of destruction of structures under the condition of real strong earthquake motions. The basic performances of "E-Defense" are maximum loading capacity 1,200 tons, maximum velocity 200 cm/s and maximum displacement 2 m p-p for horizontal excitation and maximum velocity 70 cm/s, maximum displacement 1 m p-p for vertical excitation to realize destructive ground motion. The construction work of "E-Defense" has began at early 2000, five year after the Hanshin-Awaji Earthquake and will be completed at the beginning of 2005, ten years after that Earthquake. Now, we are conducting the construction works of the facility at the Miki-city, near Kobe-city, and the manufacturing of actuators, oil-pressure supply system and other major parts of shaking table at the Mitsubishi Heavy Industry Co. "E-Defense" is the very large scale and high performance testing facility in the world. Therefore, many researchers, which are belonging not only Japanese but also worldwide organizations, can use this facility for their researches. "E-Defense" should be operated the international common use. For the international collaboration and the dissemination of research results (including test data), Earthquake Engineering Network ("EE-net") will also construct until the completion of "E-Defense". EE-net will connect, through a high performance Internet, distributed major earthquake engineering research organization. We consider that the researchers together from worldwide and research projects will determine and evaluate by the International Committee. We hope that "E-Defense" and EE-net will be situated to one of the cooperative research organization for the earthquake disaster mitigation in the world.

The primary objective of the experiment was to assess the performance of steel sheet pile quay walls subjected to liquefaction/lateral spreading. Two 5.5 m deep quay walls were designed and constructed, to investigate the damage mechanism of steel sheet pile quay walls. They were constructed with seismic design coefficients of k = 0.15 and k = 0 separately. The test site was reclaimed with dredged fine sand about 18 months before the test. The depth of the reclaimed sand layer was about 8 m and the test field area was around 4800 m (super 2) (50 m by 96 m). Controlled blast technique was used to induce liquefaction/lateral spreading, and 127 blast holes each consisting 4 kg explosive material for lower part and 3 kg for upper part were charged. The total weight of explosive material was 840 kg. Various structures such as group pipe piles, gas pipes and buried structures were installed with measuring instruments. Two liquefaction remediation methods and several new measurement techniques were adopted. Fourteen organizations were participated in the project.

It is shown that (1) The total earth pressure before liquefaction is induced mainly by the inertial force of the building. The shear force at the pile heads corresponds to the difference between the total earth pressure and the inertial force; (2) The total earth pressure after liquefaction is induced mainly by the soil deformation. The shear force at the pile heads corresponds to the sum of the total earth pressure and the inertial force of the building; (3) The relation between the relative displacement and the total earth pressure is linear before liquefaction. It becomes nonlinear with the development of pore water pressure and the total earth pressure decreases with cyclic loading after liquefaction; (4) The peak value of the total earth pressure for the super-structure with a low natural frequency is larger than that with a high natural frequency. This is probably because the inertial force of the super-structure with a low natural frequency may interrupt the response of the footing that tends to move with the ground.

Since the Niigata Earthquake in 1964, the necessity of strong motion observation has been widely recognized and the Ministry has been positively promoted the installation of seismometers in dams. Nowadays, the 413 dams under the jurisdiction of the Ministry have seismometers and the high-density observation of earthquake records can be conducted. Furthermore, the network of observation of earthquake records at dam sites has been speeded, the 236 seismometers at 50 dam sites have been connected to the Public Works Research Institute (PWRI), presently the National Institute for Land and Infrastructure Management (NILIM). This report describes the present state of earthquake data measurement at dams under jurisdiction of MLIT, the characteristics of collected data, and the outline of the dam-site seismograph network that is now being constructed.

Tokyo Bay mouth area is given as an example of target site. The most influential earthquake out of possible events around the area is selected as a scenario earthquake; its location and size are assumed the same as those of the 1923 Kanto earthquake. The L2 motion is evaluated following numerous strong motion simulations assuming various source fault models for the scenario earthquake. A stochastic Green's function method is proposed and applied to the simulations. The L2 motion is compared with probabilistic seismic hazard and the input motions specified in the current design specification for highway bridges.

In the physical mechanism explored here changes in the stratification of the Southern Ocean due to the cooling of North Atlantic Deep Water (NADW) during glacial maxima reduce the rate of vertical mixing the surface water with the deep water. A box model of the climate system is used to demonstrate the above physical mechanism and its effect on the atmospheric CO (sub 2) . The CO (sub 2) variations are not essential to the existence of the glacial cycles in the sea ice switch mechanism, yet they are shown to amplify the glacial-interglacial variability, consistent with the view of the role of CO (sub 2) deduced from proxy observations.

The ground motion is characterized by a large residual movement of the ground across the fault rupture that crosses the viaduct. Analysis indicates that the ground motion induces response that exceeds the design capacities of the seismic isolation systems thus resulting in substantial damage to the bearings and energy dissipation units, which is consistent with post-earthquake field observation. The analysis also indicates that shear keys, both longitudinal and transverse, play a critical role in preventing the superstructure collapse.

The revised specifications are based on the Performance-based Design Code Concept and the improved knowledge on the seismic design methods for highway bridges are also included. According to the Performance-based Design Code Concept, the design requirements are clearly specified and the existing detailed design methods including the analytical methods and the allowable limits are specified as verification methods and/or the examples of acceptable solutions. The designers can modify or select other verification methods and/or acceptable solutions with appropriate verifications. It is expected that new ideas on the materials and structures will be employed much easier than before. In this paper, the revised major points in the 2002 JRA Seismic Design Specifications are briefly described including the performance-based design code concept, seismic performance levels, the seismic design force, and the ductility evaluation methods for foundations and superstructures.

These models were derived from a large database of matching sediment chemistry and toxicity data, which includes contaminant gradients from a variety of habitats in coastal North America. Chemical concentrations corresponding to a 20, 50, and 80% probability of observing sediment toxicity (T20, T50, and T80 values) were calculated to illustrate the potential for deriving application-specific sediment effect concentrations and to provide probability ranges for evaluating the reliability of the models. The individual chemical regression models were combined into a single model, using either the maximum (P sub(Max) model) or average (P sub(Avg) model) probability predicted from the chemicals analyzed in a sample, to estimate the probability of toxicity for a sample. The average predicted probability of toxicity (from the P sub(Max) model) within probability quartiles closely matched the incidence of toxicity within the same ranges, demonstrating the overall reliability of the P sub(Max) model for the database that was used to derive the model. The magnitude of the toxic effect (decreased survival) in the amphipod test increased as the predicted probability of toxicity increased. Users have a number of options for applying the logistic models, including estimating the probability of observing acute toxicity to estuarine and marine amphipods in 10-d toxicity tests at any given chemical concentration or estimating the chemical concentrations that correspond to specific probabilities of observing sediment toxicity.

It was found that the absolute percentage error distribution is skewed and asymmetrical. Since the MAPE understates accuracy, MAPE-R, a variant of MAPE derived from the transformed absolute percentage error distribution was accepted as more accurate. Using simple extrapolated projections as a standard to compare forecast error, the findings suggest that the Census Bureau's projections are fairly accurate over a short projection horizon.

Laboratory tests showed that the smallest fish (31-40 mm L sub(T)) chose fine sediments (muddy and fine sands), fish 51-70 mm had high selectivity (primarily medium sand), and the largest fish (80-150 mm) were not selective although they avoided the largest grain-sizes (pebbles and granules). Sediment preferences were correlated with size-dependent burial capabilities. Beam trawl collections were made over a 6 year period in Kachemak Bay, Alaska, to examine the distribution of yoy Pacific halibut (14-120 mm L sub(T)) using small size classes (e.g. 10 mm intervals). Canonical correlation analysis showed that the per cent of sand in the sediment was a highly significant variable for all but one size and date combination. Catch per unit of effort (CPUE) for newly settled fish (<30 mm L sub(T)) was highest on very fine sand, fish 41-80 mm were most abundant on fine sand, and the largest yoy fish (81-120 mm) were abundant over a range of sediments from fine sand to mud. Except for the smallest fish, Pacific halibut in the field were associated with sediments somewhat finer than predicted from the laboratory experiments; however, virtually all were captured where they could bury easily. The ability of flatfish to bury and shelter in sediment is related to fish size; consequently, habitat associations shift rapidly during the first year of life. Habitat models for yoy flatfishes should consider size-dependent shifts in capabilities and preferences.Copyright 2002 The Fisheries Society of the British Isles. Published by Elsevier Science Ltd.

This estimator uses the horizontal polarization radar reflectivity Z sub(e), differential reflectivity Z sub(DR), and specific differential phase shift K sub(P), and it intrinsically accounts for changes in how drop oblateness increases with size. Because this estimator uses power measurements (i.e., Z sub(e), and Z sub(DR)), a procedure for correcting these measurements for effects of partial attenuation and differential attenuation using the differential phase measurement is suggested. An altitude correction for estimates of rainfall rates is also suggested. The proposed combined polarimetric estimator that uses K sub(DP), Z sub(DR) and Z sub(e), an estimator that uses K sub(DP), alone for equilibrium drop shapes, and different Z sub(e)-R relations were applied to the 15 rain events observed with the NOAA X-band transportable polarimetric radar during the eight-week field campaign at the NASA Wallops Island facility in Virginia. The observed rains ranged from very light stratiform events to very heavy convective ones with cells producing rainfall rates in excess of 100 mm/h. The three different ground validation sites were equipped with high-resolution (0.01 in.) tipping-bucket rain gauges. One of these sites also was equipped with disdrometers. In terms of the relative standard deviation, the combined polarimetric estimator provided the best overall agreement with gauge data (22%), closely followed by a case-tuned Z sub(e)-R relation (23%) that was determined for each observational case from drop size distributions (DSD) measured in situ by a disdrometer and was available only a posteriori. The use of the K sub(DP)-only estimator and a mean Z sub(e)-R relation resulted in 30% and 32% relative standard deviations, correspondingly. The combined polarimetric estimator, the K sub(DP)-only estimator, and the case-tuned Z sub(e)-R relation estimator provided about a 6%-9% negative bias in comparison with the gauge data; the mean Z sub(e)-R relation estimator provided a larger negative bias (18%).

Fish and salamander densities and sizes were compared between different habitat types (pools and riffles) in summer and winter. Species density, length, and diversity (richness and dominance) were also correlated with physical variables measured at the reach and watershed scales. In the summer, densities of coho salmon O. kisutch, cutthroat trout O. clarki, and larval lampreys were significantly higher in pools than in riffles (P < 0.01), whereas densities of age-0 torrent sculpins were higher in riffles than in pools (P < 0.01). In winter, densities of coho salmon, cutthroat trout, steelhead O. mykiss, and young-of-the-year trout fry were higher in pools than in riffles (P < 0.01). Cutthroat trout, steelhead, Pacific giant salamanders, and torrent sculpins found in pools were larger than those found in riffles during summer (P < 0.01). Steelhead and young-of-the-year trout fry were heavier for a given length in pools than in riffles, whereas both reticulate and torrent sculpins were lighter (P < 0.01).

Each spring from 1997 to 2000, we released 197-299 lamprey with surgically implanted radio transmitters. Unique transmitter codes and the date and time of reception at each antenna site were downloaded electronically, and initial processing was conducted to eliminate false positive signals. The resulting large Oracle database was analyzed using an ArcView-based coding protocol. Underwater antennas positioned outside the fishway entrances detected lamprey approaches, and antennas positioned immediately inside the entrances indicated successful entries. Entrance efficiency (the number of lamprey that successfully entered a fishway divided by the number that approached that fishway) was compared for different types of entrances (main entrances versus orifice entrances) and entrance locations (powerhouse versus spillway). Lamprey used orifice-type entrances less frequently than main entrances, and passage success was generally low (< 50%) at all entrances to fishways at Bonneville Dam (the lowest dam in the system). Lamprey activity at the entrances was highest at night, and entrance success was significantly higher at the Dalles Dam (the next dam upstream from Bonneville Dam) than at Bonneville Dam. In 1999 and 2000, construction modifications were made to Bonneville Dam spillway entrances, and water velocity at these entrances was reduced at night. Modifications to increase lamprey attachment at the entrances improved lamprey entrance efficiency, but entrance efficiency during reduced velocity tests was not significantly higher than during control conditions.

The conventional method of using greased glass stoppers have been found to cause an increase in oxygen concentration by 12% over 1-month period as a result of evaporation of water sample through micro-gaps and concurrent intrusion of air into the water sample bottles. Sealing the sample bottles with water has been found to be the optimal storage method. It permits a 100.2 plus or minus 0.3% recovery of dissolved oxygen concentration from storage seawater samples over 4 months.

In this system, a linear two-dimensional Princeton Ocean Model with an orthogonal curvilinear grid system is used as the forward model. The wind drag coefficient is used as a convenient control variable (approximately representing errors in the forecasting wind fields that are usually the primary cause of errors in model-produced water levels). The cost function is defined in terms of the water level misfits between the observations and model outputs. The limited memory Broyden-Fletcher-Goldfarb-Shanno (BFGS) quasi-Newton method for large-scale optimization is implemented to minimize the cost function. Identical twin experiments with model-generated pseudo-observations are performed and the results show that the true solution of the control variable can be recovered efficiently by assimilating pseudo-observations at limited locations into the model. The results from actual subtidal water level data assimilation experiments show that the simulated subtidal water levels with data assimilation are better than those without data assimilation even if only one control variable is used. The results from the experiment with 16 control variables demonstrate that the correlation coefficients are greater than 0.93 and the RMS errors are less than 5.3 cm at 18 coastal water level gauge stations. The nowcast/forecast experiments demonstrate that the subtidal water level forecasts are improved by water level data assimilation in the first 6 h. The average RMS error of the subtidal water level forecasts over the 18 water level gauge stations is reduced by 3 cm.

In the early summer of both years, an area of maximum domoic acid (DA) accumulation was located approximately 50 km off the coast within a counterclockwise, cold feature known as the Juan de Fuca eddy. The stations in the eddy with the highest domoic acid concentrations coincided with high numbers of Pseudo-nitzschia pseudodelicatissima (Hasle) Hasle (2.7 mu g DA equivalents L super(-1), up to 0.6 X 10 super(6) cells L super(-1) in 1997 and 0.2 mu g DA equivalents L super(-1), up to 0.2 X 10 super(6) cells L super(-1) in 1998), a species known to produce toxin in this region. Other known toxin-producing species were sometimes present, but at 0.1 mu g DA equivalents L super(-1) were measured. In 1998, large-scale surveys indicated that high levels of particulate DA in seawater persisted at least until 1 October, covering a maximum area of 100 km super(2) off the Washington coast in midsummer. The appearance of high levels of DA (up to 2.7 mu g DA equivalents L super(-1)), coincident with high numbers of P. pseudodelicatissima (up to 15.4 X 10 super(6) cells L super(-1)) at Kalaloch beach on the central coast in late September, was followed by the accumulation of record levels of toxin in razor clams. This toxic episode was preceded by a downwelling-favorable wind event, with associated onshore transport in near-surface layers. We suggest that the Juan de Fuca eddy may be one source of DA to the Washington coast. The duration of upwelling and the exact timing of fall storms likely play an influential role in the intensity of the bloom and the movement of toxic cells from the eddy to the coast.

Wave grouping characteristics in nearshore Great Lakes. Ocean Engineering 27, 1221-1230) exploratory study on wave grouping characteristics in the nearshore Great Lakes. We analyze recent GLERL time-series measurements recorded by pressure sensors deployed at four nearshore stations in southern Lake Michigan during 1998-1999. With the advantage of continued application of time-frequency wavelet spectrum analysis, the extensive new measurements substantially confirmed the effectiveness of the empirical characterization of wave grouping parameters defined in Liu. We show that a wave group is really the basic element for a detailed understanding of wave processes, in contrast to the conventional approach of using a frequency spectrum as the basic element, which depends on the recording length and requires the data to be stationary. While studying wave time-series alone does not really alleviate the vast intricacies of the wind wave processes, the embodiment of wave grouping as the predominant feature in the wind wave processes clearly represents a significant step forward toward sound conceptual advancement.

A two-continuum formulation is used in which the gas phase and the water-mist are both described by equations of the Eulerian form. The water-mist model is coupled with previously developed codes based on the multi-block Chimera technique for simulating fires. Computations are performed to understand the various physical processes that occur during the interaction of water-mist and fires in large enclosures. Droplet sectional density contours and velocity vectors are used to track the movement of water-mist and to identify the regions of the fire compartment where the droplets evaporate and absorb energy. Parametric studies are performed to optimize various water-mist injection characteristics for maximum suppression. The effects of droplet diameter, mist injection velocity, injection density, nozzle locations and injection orientation on mist entrainment and flame suppression are quantified. Numerical results indicate that for similar injection parameters such as mist injection density, injection velocity and droplet diameter, the time for suppression was smallest for the top injection configuration. Water-mist injection through the side walls, the front and rear walls and through the floor were found to be less efficient than the top injection configuration. These results are compared with our earlier predictions on water-mist suppression of small scale methanol pool fires and other experimental studies.

AN - 36417021; 9595 AB - PURPOSE: A fifth amendment to the management plan for rock shrimp fishery in the South Atlantic Exclusive Economic Zone (EEZ) is proposed. The fishery is affected by unregulated commercial fishing, significant bycatch, lack of consistent regulations, noncompliance to regulations by fishermen participating in a transboundary penaeid shrimp fishery, the potential for release of exotic species, habitat alteration due to human activities, incomplete and inadequate data on the status of the fishery, excess fishing capacity, excessive harvest, and little incentive for conservation and regulatory compliance. The proposed amendment would: establish a license limitation program for the fishery within the South Atlantic Fishery Management Council's jurisdiction and limit initial eligibility to boat owners/vessels that have held a valid rock shrimp permit prior to December 31, 1999, and can demonstrate landings of at least 15,000 pounds in any one year from 1996 to 1999; require captains operating permitted vessels fishing for rock shrimp in the EEZ to have a vessel operator's permit issued by the National marine Fisheries Service; require the minimum allowable mesh size for a trawl used to fish in the EEZ to be 1-and-7 /8th-inch stretched mesh; require that any vessel fishing for rock shrimp in the EEZ must use an approved vessel monitoring system, the cost of which would not exceed $2,500 for equipment and installation; and require that the foregoing management measures would apply to all vessels fishing in the EEZ. Numerous options, including a No Action option, are compared with the proposed action in this final EIS. POSITIVE IMPACTS: In general, the amendment would assist in the protection of the rock shrimp stock, while protecting the economic interests of vessel owners. Owners of vessels that qualify for a limited entry permit would probably harvest additional quantities of shrimp. The permit process would improve compliance with fishery management regulations. NEGATIVE IMPACTS: The limited entry program could result in short-term loss of revenue for owners of 102 vessels and their crews. Permit requirements, gear limitations, and monitoring system could increase operating expenses for vessel owners. Limitations in place following passage of the amendment would place some constraints on the social life of the affected fishermen.

Nine of the 117 tagged fish were recovered in Seguam Pass during September 2000. Fish were tagged externally just below the dorsal fin. Atka mackerel displayed strong diel behavior, with vertical movements away from the bottom occurring almost exclusively during daylight hours and little to no movement at night. Vertical movements occurred when light levels at 150 m were greater than 7.31 x 10 super(-5) mu mol photons m super(-2) s super(-1), or approximately between 08:00 and 23:00 h Alaska Daylight Time (ADT; GMT - 8) during August. Daytime vertical movements were correlated with light intensity, time of day and current velocity. The occurrence of vertical movements tended to increase with increasing light during the morning and early afternoon, but then decrease with increasing hour of the day after 13:00 h ADT. The magnitude of surface-directed vertical excursions was reduced during spring tide periods, when current velocities are highest. By comparison, the magnitude of slope-directed excursions was greater during spring tide periods and reduced during neap tide periods. Eight fish were at liberty for 42 to 44 d and 1 for 65 d. Two of the tagged males displayed nest guarding behavior for the majority of their time at liberty. Depths for these 2 males (115 to 117 m) were much deeper than previously observed for Atka mackerel spawning grounds. Given that Atka mackerel are more likely to be on the bottom during the night and less likely during the day, the variance of abundance estimates from bottom trawl surveys may be reduced by accounting for these diel differences.

AN - 36411235; 9578 AB - PURPOSE: The establishment of a fishery management plan (FMP) for the Northeast Region's skate complex by the New England Fishery Management Council. The species to the FMP would apply include winter skate, barndoor skate, thorny skate, smooth skate, little skate, clearnose skate, and rosette skate. The geographic reach of the plan extends from Cape Hatteras, North Carolina to the northern most coastal point of Maine. The unit extends from the coastline of the continental United States to the Hague Line and the outer edge of the E.S. Exclusive Economic Zone. The plan would designate a management unit, establish a fishing year, specify overfishing definitions for each skate species, specify essential fish habitat for skates, specify a rebuilding program for overfished species, initiate mechanisms for FMP review and monitoring, specify a framework adjustment process, and adopt a "baseline" of management measures in other fisheries that benefit the skate resources and establish a process to review changes to the baseline measures. In addition, the FMP would provide options for development of a federal permit program for skates, development of a catch reporting program for skates, modifications to current reporting requirements for all vessels and dealers, requirement of a letter of authorization for direct sales of skate bait, possession limits for skate the wing fishery, and prohibitions on the possession, landing, and/or sale of certain skate species. Measures proposed in the FMP would be implemented in 2003. In general, each measure outlined under the plan would be independent of other measures. For example, the option that could be selected for the federal permit program would not influence or change the option that may be selected for the skate wing possession limit. Other important issues in this FMP involve the need for more biological and fishery information for skates and the challenges of species-specific skate identification. POSITIVE IMPACTS: The FMP would prevent overfishing within the management unit and reduce bycatch within the fishery. The measures in the FMP that provide for collection of better species-specific and fishery information could prove to be most beneficial in the long-term by providing more accurate information to monitor the FMP and enhance management decision-making. NEGATIVE IMPACTS: Restrictions placed on fishing would result in some social and economic impacts, on communities, ports, vessel owners and crews, and dealers, but these impacts would be minor. Restrictions on the possession of skates would have the greatest negative social and economic impacts. Minor, short-term social impacts would also result from changes to reporting requirements, regulatory discarding from species prohibitions and possession limits.

AN - 16343574; 9579 AB - PURPOSE: An amendment to the Atlantic surfclam and ocean quahog fishery management plan (FMP) is proposed. The FMP, which is administered by the Mid-Atlantic Fishery Management Council, was established in 1977 and has been amended 12 times since. The area covered by the plan is the Atlantic Ocean within the U.S. Exclusive Economic Zone. The ocean quahogs managed under the FMP would include a small-scale marine ocean quahog fishery in eastern Maine, where small ocean quahogs are harvested generally for sale for the half-shell market. Locally, these small marine ocean quahogs are known as "mahogany quahogs" and have fallen under the management plan since the implementation of the 10th amendment to the FMP in 1997. Surfclams are not overfished, nor does it appear likely that the species will be overfished in the future. A fishing gear workshop concluded that there is sufficient information to indicate that clam dredges could have an effect on essential fish habitat (EFH) if the gear is fished improperly or in the wrong sediment type, though neither of these situations seems to occur at present. The proposed amendment would rectify the two disapproved isssues (the surfclam overfishing definition and fishing gear impacts to EFH) resulting from the previous amendment to the FMP, consider the establishment of multi-year quotas, implement a vessel monitoring system, and reverse the surfclam minimum size limit specifications such that instead of a regulatory action associated with the suspension of the minimum size limit each year, there would only be a regulatory action to implement the minimum size limit. More specifically, the plan would redefine overfishing; retain the status quo for fishing gear restrictions to prevent excessive impacts to essential fish habitat, though additional clarification of the restrictions would be provided; provide for no multi-year quotas; retention of the surfclam minimum size limit; and implement no vessel monitoring system. POSITIVE IMPACTS: The amendment would continue the effective management of the two species while preventing future overfishing. The plan would preserve and rebuild the sufclam and quahog resources by stabilizing annual harvest rates throughout the management unit in a manner that would minimize short-term economic dislocations. Regulatory requirements and the associated costs would be minimized. Harvesting capacity would be balanced with processing and biological capacity. The management regime and regulatory framework would NEGATIVE IMPACTS: The dredging gear used for fishing the species would result in some slight, short-term bottom disturbances and localized, short-term sedimentation in near-shore areas.

Filter samples from the aircraft were compared with "normal use" and "pristine clean" filters using SEM, energy-dispersive x-ray spectrometer, and Nicolet FTIR spectrophotometer analyses. These analyses confirm that the DC-8 encountered airborne volcanic ash from Hekla Volcano. This result is supported by independent onboard heated aerosol observations at the time of the encounter. The analyses further demonstrate the ambiguous nature of the dual band thermal IR ("split window") method for detecting volcanic ash from the point of view of aviation safety. They also highlight the utility of in situ aircraft filter-based observations of volcanic aerosols for scientific purposes. Abstract Copyright (2002), by the Chinese Geophysical Society.

We report the isolation and characterization of a 4-gene cluster, tapABCD, from virulent A. salmonicida A450 that encodes proteins homologous to components required for type IV pilus biogenesis. One gene, tapA, encodes a protein with high homology to type IV pilus subunit proteins from many Gramnegative bacterial pathogens, including Aeromonas hydrophila, Pseudomonas aeruginosa, and Vibrio vulnificus. A survey of A. salmonicida isolates from a variety of sources shows that the tapA gene is as ubiquitous in this species as it is in other members of the Aeromonads. Immunoblotting experiments demonstrate that it is expressed in vitro and is antigenically conserved among the A. salmonicida strains tested. A mutant A. salmonicida strain defective in expression of TapA was constructed by allelic exchange and found to be slightly less pathogenic for juvenile Oncorhynchus mykiss (rainbow trout) than wild type when delivered by intraperitoneal injection. In addition, fish initially challenged with a high dose of wild type were slightly more resistant to rechallenge with wild type than those initially challenged with the tapA mutant strain, suggesting that presence of TapA contributes to immunity. Two of the other three genes identified, tapB and tapC, encode proteins with homology to factors known to be required for type IV pilus assembly in P. aeruginosa, but in an as yet unidentified manner. TapB is a member of the ABC-transporter family of proteins that contain characteristic nucleotide-binding regions, and which may provide energy for type IV pilus assembly through the hydrolysis of ATP. TapC homologs are integral cytoplasmic membrane proteins that may play a role in pilus anchoring or initiation of assembly. The fourth gene, tapD, encodes a product that shares homology with a family of proteins with a known biochemical function, namely, the type IV prepilin leader peptidases. These bifunctional enzymes proteolytically cleave the leader peptide from the pilin precursor (prepilin) and then N-methylate the newly exposed N-terminal amino acid prior to assembly of the subunits into the pilus structure. We demonstrate that A. salmonicida TapD is able to restore type IV pilus assembly and type II secretion in a P. aeruginosa strain carrying a mutation in its type IV peptidase gene, suggesting that it plays the same role in A. salmonicida.

AN - 16357536; 9463 AB - PURPOSE: The review of fishery management plans (FMPs) for salmon fisheries off the coasts of southeast Alaska, Washington, Oregon, and California, and in the Columbia River basin is proposed in this programmatic draft EIS. The causes of salmon population declines in the study areas are manifold and are rarely, if ever, solely a result of harvest impacts. The plan described in this document represents an attempt to provide fishery review flexibility and to provide an overview of fishing management methods and strategies that could be implemented as part of the annual FMP process planning. Three alternatives, including a No Action Alternative (Alternative 1), which would perpetuate the existing FMP regimes, are considered in this draft EIS. Alternative 2 would reduce chinook non-retention fisheries in southeastern Alaska. With respect to Pacific Coast fisheries, Alternative 2 would also maximize the duration of sport fishing seasons and the value of commercial harvest while meeting conservation standards or meet or exceed conservation objectives while approximating the fishing opportunity under the current FMP regime. With respect to the Columbia River basin, Alternative 2 would either allow harvesting of surpluses of naturally spawning unmarked fish in areas where the abundance of federally protected species is low or prohibit the harvest of surpluses of naturally spawning fish. With respect to the southeast Alaska fishery, Alternative 3 would close all commercial troll and recreational salmon fisheries, with the exception of terminal area experimental fisheries and foregoing Alaska hatchery runs ans leave the gillnet and purse seine fisheries directed at sockeye, chum, pink, and coho salmon open. With respect to the Pacific Coast and Columbia River fisheries, Alternative 3 would allow no incidental take or salmon and close the fishery. POSITIVE IMPACTS: The planning effort would seek to protect salmonid resources, seek to maximize long-term socioeconomic benefits, and meet national treaty obligations to Native American tribes. Restrictions on fishing would allow stocks of federally protected and other species to revive, protecting the economic, social, and cultural value of the fisheries. Restrictions would also result in increased fishing effort relative to catch in some areas. NEGATIVE IMPACTS: Restrictions on fishing would result in socioeconomic hardships for some fishing communities, including Native American communities. Removal of restrictions would result in decreases of salmonid populations, including populations of federally protected species of salmon.

AN - 36413092; 9465 AB - PURPOSE: The provision of shore protection for the shoerline surrounding Phipps Ocean Park within the town of Palm Beach, Florida is proposed. The study area suffers from critical erosion due to littoral drift attributable to Lake Worth Inlet and the adjacent armored shoreline and the existing headland features surrounding the area. Shoreline conditions and structures updrift of the project area exacerbate the erosion problem and, if remedial action is not taken, these conditions will lead to significant future erosion along the project area shoreline and the shoreline to the south. The recommended plan (Alternative 3) would include placement of approximately 1.5 million cubic yards of fill over approximately 1.9 miles of beach, between Florida Department of Environmental Protection (DEP) Monuments R-116 and R-126 and installation of 3.1 acres of hardbottom reef. Sand compatible with the existing beech would be obtained from two borrow areas located approximately 3,500 feet offshore between 1.5 and 2.6 miles south of the fill site. Fill would be transferred from the orrow areas by hydraulic dredge; construction by hopper dredge would not be allowed to avoid impacts to hardbottom biological communities in the vicinity of the borrow areas. Geotechnical analysis of the borrow area indicates that the material is suitable for he restoration of the beach and suitable for use by nesting sea turtles and subsequent hatching success. The borrow areas have been designed with buffer zones to avoid impacts to hardbottom communities in the vicinity of the areas. Mitigation of hardbottom communities within the fill area would be implemented. In addition to the proposed action, this draft EIS considers a No Action Alternative (Alternative 1) an alternative involving beach nourishment in combination with the placement of groin structures (Alternative 2). Estimated costs of initial fill, mitigation measures, and renourishment measures under the preferred alternative are $8.55 million, $750,000, and $5.1 million, respectively. POSITIVE IMPACTS: The recommended plan would mitigate long-term erosion impacts along Lake Worth Inlet and the armored coastline north of the project area; provide and maintain storm protection to upland improvements in the area; restore and maintain the beach for public recreational use; and restore and maintain the beach for marine turtle nesting purposes. NEGATIVE IMPACTS: Dredging from the borrow sites and deposition of dredged sand at the shoreline would result in destruction of benthic organisms and benthic habitat, though benthic habitat at the dredging sites would recover. Hardbottom habitat would be significantly disturbed. During deposition of sand along the shoreline, recreational uses of the beach would be marred significantly. Beach fill activities could impact sea turtle nesting and/or hatching success. Dredging would result in a temporarly increase in turbidity in the localized water column.

AN - 36423080; 9459 AB - PURPOSE: The issuance of an incidental take permit (ITP) to the Simpson Resource Company (Simpson) and an enhancement of survival permit (ESP) and the implementation of a aquatic habitat conservation plan (AHCP) and candidate conservation agreement (CCA) for lands and waters in Del Norte and Holboldt counties, California are proposed. The study area includes all commercial timberland acreage within the 11 hydrographic planning areas on the western slopes of the Klamath Mountains and the Coast Range of California in the two counties, where Simpson owns lands or harvesting rights. The area encompasses 416,531 acres, including approximately 1,866 acres of lands on which Simpson owns perpetual harvesting rights. The study area would be adjusted during the permit term to reflect real property transactions involving Simpson. The permits would be issued under the Endangered Species Act of 1973 (ESA). The ITP would allow Simpson to take several fish species listed as threatened under the ESA that could be impacted by otherwise lawful timber harvesting and forest management activities conducted on Simpson's lands in northern California. The potentially affected species include Coho salmon, Chinook salmon, and steelhead trout. The ITP and the ESP would also cover other, currently unlisted, aquatic species should they become listed in the future. The unlisted species include Chinook salmon, steelhead trout, costal cutthroat trout, rainbow trout, southern torrent salamander, and tailed frog. Certain species are listed in some areas and not in others, resulting in the overlap of listed and unlisted species. Simpson could conduct timber harvesting and other covered activities under the proposed permits and plans, but could also conduct these activities without the permits and plans. In addition to the proposed action, this draft EIS considers a No Action Alternative and three other action alternatives. POSITIVE IMPACTS: The AHCP and the CCA would likely provide for improved aquatic conditions relative to the situation under which no such planning was in place. Anadromous fish populations would likely increase and habitat conditions for these species would be improved substantially. NEGATIVE IMPACTS: Timber harvest and related activities, such as road construction, would affect aquatic and terrestrial habitat due to destruction of vegetation, disturbance of soils, and the associated degradation of water quality through increased sediment levels. However, the AHCP and CCA would reduce these damages significantly. Prescribed burning would contribute to these environmental damages and would result in temporary degradation of air quality in the area. Harvest-related activities would mar visual aesthetics and otherwise degrade the recreational experience associated with the area.

We estimated growth using otolith microstructure from free-ranging fish collected in different habitat types and also measured growth of red drum in experimental enclosures where fish movement was restricted. Otolith growth was closely related to somatic growth in fish of 13 to 33 mm SL, and we used daily otolith increments from the last 10 d before capture as an indicator of growth following settlement into estuarine habitats. Growth rates of red drum captured at marsh, nonvegetated, and seagrass sites were not significantly different; no fish were collected on oyster reef. While reducing potential problems of a lagged response between otolith growth and somatic growth, the use of a 10 d growth period may have increased the likelihood of fish movement among habitats affecting our comparisons. The overall post-settlement growth rate of 0.45 mm d super(-1) was similar to rates reported in the literature. Movement among habitat types was eliminated in experiments employing 24 solid-walled enclosures (60 cm diameter). Growth rates in enclosures over the 7 d experiment were 0.12 mm d super(-1) in oyster reef, 0.21 mm d super(-1) on nonvegetated bottom, 0.40 mm d super(-1) in salt marsh, and 0.42 mm d super(-1) in seagrass; rates in vegetated enclosures approximated natural growth rates. Significantly higher growth in marsh and seagrass enclosures suggests that growth potential for red drum may be highest in these vegetated areas. However, growth results in enclosures need to be evaluated carefully, because fish movement among habitat types may be important in these shallow estuarine systems.

The analysis is based on DIN and PN models that were combined with spatially explicit global databases. The model results indicate the widely uneven geographic distribution of human activities and rates of nitrogen input to coastal systems at the watershed, latitudinal, and regional-continental scales. Future projections in a business-as-usual scenario indicate that DIN export rates increase from approximately 21 Tg N yr super(-1) in 1990 to 47 Tg N yr super(-1) by 2050. Increased DIN inputs to coastal systems in most world regions are predicted by 2050. The largest increases are predicted for Southern and Eastern Asia, associated with predicted large increases in population, increased fertilizer use to grow food to meet the dietary demands of that population, and increased industrialization. Results of an alternative scenario for North America and Europe in 2050 indicate that reductions in the human consumption of animal protein could reduce fertilizer use and result in substantial decreases in DIN export rates by rivers. In another scenario for 2050, future air pollution control in Europe that would reduce atmospheric deposition of nitrogen oxides in watersheds is predicted to decrease DIN export by rivers, particularly from Baltic and North Atlantic watersheds. Results of a newly developed global PN river export model indicate that total global PN and DIN export by rivers in 1990 are similar, even though the global distribution of the two differ considerably.

Chemical analyses and multiple toxicity tests were performed on 226 surficial sediment samples collected over an area of 484 km super(2) in greater Biscayne Bay, including saltwater reaches of several tributaries. Benthic samples were collected and analyzed at one-third of the locations. One or more chemical concentrations exceeded effects range median (ERM) values in 35 samples, representing an area of 5.4 km super(2) (1.1% of the survey area). Highly toxic conditions in amphipod survival tests occurred in 24 of the samples, representing 62 km super(2) (13% of the area). Highly significant results were more frequently observed in three sub-lethal tests: sea urchin fertilization (affecting 47% of the area), sea urchin embryological development (84% of the area), and microbial bioluminescence (51% of the area). The highest levels of chemical contamination (range in mean ERM quotients of 0.2 to 2.0, average 0.76) were observed in samples from the lower Miami River. The high degree of contamination in the river contrasted sharply with conditions in the bay, where chemical concentrations generally were much lower (range in mean ERM quotients of 0.005 to 0.21, average 0.04). Amphipod survival tests showed a very high degree of correspondence with a gradient in chemical contamination in the river and adjoining reaches of the bay. Correlation analyses, scatter plots, and principal component analyses indicated that both amphipod survival in the laboratory tests and the abundance and diversity of the benthos decreased sharply with increasing concentrations of mixtures of organic compounds and trace metals in the sediments. The triad of analyses provided a strong weight of evidence of pollution-induced degradation of sediment quality in the riverine locations.

This was particularly thought to be the case for the amphipod, Diporeia spp. that encapsulates the fecal material in a peritrophic membrane. The elimination of selected PAH congeners by Diporeia spp. was determined in the presence of three solid substrates and under water only conditions. The elimination was generally enhanced by the presence of a solid substrate whether or not the organism employed the material as a food source. The greater the sorptive capacity of the substrate, the greater its influence on the elimination process. Elimination via the fecal route was generally insignificant except for the elimination of BaP in the presence of sediment. In this case, the fecal elimination accounted for up to 40% of the total elimination, and the extent of elimination via the fecal route increased with the amount of fecal material produced. Thus, it is clear from the above effort that the main mechanism for elimination of contaminants in the presence of a substrate is primarily via passive diffusion from the organism with subsequent sorption to the solid substrate, which maintains the chemical activity gradient between the organism and the water. This effort refutes the earlier hypothesis that fecal elimination is the dominant route of elimination for Diporeia spp., and that the peritrophic membrane plays any substantial role in the elimination process.

We deployed experiments on the forereef slope off Lee Stocking Island, Bahamas, and on the continental shelf and slope of the Gulf of Mexico for 2 yr in 18 distinctive EODs at depths from 15 to 530 m. Overall, most shells deployed at most sites had relatively minor changes in shell condition. Most EODs generated relatively similar taphonomic signatures. A few sites did produce taphonomic signatures clearly distinguishable from the central group and these sites were characterized by one or more of the following: high rates of oxidation of reduced compounds, presence in the photic zone, and significant burial and exhumation events. Thus, unique taphonomic signatures are created by unique combinations of environmental conditions that include variables associated with regional gradients, such as depth and light, and variables associated with edaphic processes, such as the seepage of brine or petroleum or the resuspension and redeposition of sediment. Most sites, however, showed similar taphonomic signatures, despite the variety of EOD characteristics present, suggesting that insufficient time had elapsed over 2 yr to generate a more diverse array of taphonomic signatures. Discoloration and dissolution were by far the dominant processes over the 2-yr deployment period. Periostracum breakdown, loss of shell weight, and chipping and breakage was less noticeable. EODs were chosen based on the expectation that the process of burial and the influence of depth and sediment type should play the greatest roles in determining between-EOD differences in taphonomic signature. EOD-specific edaphic factors often overrode the influence of geographic-scale environmental gradients. Taphonomic alteration was greater on hardgrounds and in brine-exposed sites than on terrigenous muds. Dissolution was less effective at sites where burial was greatest. Discoloration occurred most rapidly at shallower sites and on hardgrounds. Water depth was less influential in determining taphonomic signature than burial state or sediment type. The limited influence of water depth is likely due to the presence of shallow sites that, for one reason or another, were protected from certain taphonomic processes and deeper sites that were characterized by unusually strong taphonomic signals.

Aftershock and foreshock events are selected from the hydroacoustic earthquake catalog using single-link cluster (SLC) analysis, with a combined space-time metric. In the regions examined, hydroacoustic data improve the completeness level of the earthquake catalog by approximately 1.5-2.0 orders of magnitude, allowing the decay constant, p, of the modified Omori law (MOL) to be determined for individual sequences. A non-parametric goodness-of-fit test indicates six of the seven sequences examined are described well by a MOL model. The p-values obtained for individual ridge and transform sequences using hydroacoustic data are larger than that previously estimated from the analysis of a stacked sequence generated from teleseismic data. For three sequences along the Siqueiros, Discovery and western Blanco Transforms, p-values are estimated to be approximately 0.94-1.29. The spatial distribution of aftershocks suggests that the mainshock rupture is constrained by intra-transform spreading centers at these locations. An aftershock sequence following a 7.1M (sub s) thrust event near the northern edge of the Easter Microplate exhibits p = 1.02+ or -0.11. Within the sequence, aftershocks are located to the north of a large topographic ridge, which may represent the surface expression of the shallow-dipping fault that ruptured during the mainshock. Two aftershock sequences near 24 degrees 25'N and 16 degrees 35'N on the MAR exhibit higher p-values, 1.74+ or -0.23 and 2.37+ or -1.65, although the latter estimate is not well constrained because of the small number of aftershocks. Larger p-values along the ridge crest might reflect a hotter thermal regime in this setting. Additional monitoring, however, will be needed to determine if p-value differences between the ridge and transform sequences are robust. A 1999 sequence on the Endeavour segment of the JdFR, which has been correlated with changes in the hydrothermal system, is described poorly by the MOL model. The failure of the MOL model, the anomalously large number of earthquakes within the sequence and absence of a clearly dominant mainshock are inconsistent with aftershock activity and the simple tectonic origin that has been proposed previously for this sequence.

Their formation rates are reported for three density layers that span the main water masses involved in the lower limb of the Thermohaline Circulation (THC). The bottom layer is supplied via sinking of Antarctic Bottom Water (AABW). The middle layer receives the offshore injection of ventilated Modified Circumpolar Deep Water (MCDW). The top layer is ventilated by northward export of Antarctic Surface Water into the Upper Circumpolar Deep Water of the Antarctic Circumpolar Current. Average Southern Ocean inputs to the upper two layers of the deep ocean are derived on the basis of the CFC-11 distributions along meridional sections. (modified journ. abstr.)

In general, the flow in the lower 3 m is stratified on ebb and unstratified on flood and shear is concentrated near the bed on flood and nearly uniform throughout the water column on ebb. At spring tides stratification is reduced and the flows 1 m above bottom (mab) are consistently greatest at the downstream end of the bend. The along-channel density gradient is weakest during spring tides owing to zero gradient over most of ebb flow. At neap tides vertical stratification is strong enough to raise the gradient Richardson number well above 0.25 for most of the ebb tide. Currents are weaker and do not display a regular along-channel pattern. The variation in density and current structure is interpreted to result from variations in cross-channel circulation associated with the channel bend. At spring tides, the cross-channel circulation appears to be strong enough to overturn the water column whereas at neap tides stratification is strong enough to halt the overturning. Reynolds stress measured with a Benthic Acoustic Stress Sensor undergoes a four-fold increase between neap and spring tide. The drag coefficient relative to flow at 1 mab is 0.0015-0.0025. Bed stress in the bend is estimated using this drag coefficient and the maximum instantaneous velocity at 1 mab over the array. Because of the along-channel variability in current speed, the estimated bed stress is roughly twice as large as the measured Reynolds stress in the middle of the bend. The estimated bed stress is found to balance the horizontal pressure gradient and local acceleration, implying that a depth-averaged linear momentum balance adequately describes the dynamics on the bend when the impact of the cross-channel circulation is taken into account in the estimate of the bottom stress.

Such changes may, in turn, affect spatial distributions of planktivores, rates of food web interactions, and growth rate potential of fishes. We use predicted changes in water temperatures for the years 2030 and 2090 to evaluate growth rate potential of lake trout Salvelinus namaycush, chinook salmon Oncorhynchus tshawytscha, and striped bass Morone saxatilis in Lake Michigan. Changes in the timing and extent of thermal stratification changed the predicted distributions of prey fish and the spatiotemporal patterns of growth potential. Overall, growth rate potential of all piscivores increased under climate warming simulations. For chinook salmon, an assumed 15% reduction of prey abundances reduced mean growth rate potential by 9%. A comparison of measured temperatures for 1996 and 1998 showed that current warm years (1998) are similar to mean conditions predicted between years 2030 and 2090. We suggest that studies of interannual variations in food web dynamics may provide insights into the potential impact of climate on fishes.

Each of these factors may affect the fish stocks in the region. Direct effects would include a general northward shift in stock distributions in response to increased water temperatures, reduced reproductive success for some cold water species due to temperatures rising above the optimum for larval growth, and greater frequency of hypoxic conditions in coastal areas due to stronger stratification. Indirect effects may occur through changes in the processes controlling phytoplankton productivity and species composition and, subsequently, the productivity of the zooplankton populations that are the primary prey of larval fish. By influencing larval survival and recruitment, these bottom-up effects could represent the most important pathway for changes in climate to affect fish resources. However, evaluating the consequences of bottom up changes will require improved ecosystem modeling capability.

The protein is considered essential to bacteria because the gene is present in virtually all bacterial genomes but not in those of archaea or eukaryotes. The amino acid sequence shows no homology to other proteins except for the presence of the Walker A motif G-X-X-X-X-G-K-T that indicates the possibility of a nucleotide-binding protein. The YjeE protein was cloned, expressed, and the crystal structure determined by the MAD method at 1.7-AA resolution. The protein has a nucleotide-binding fold with a four-stranded parallel beta -sheet flanked by antiparallel beta -strands on each side. The topology of the beta -sheet is unique among P-loop proteins and has features of different families of enzymes. Crystallization of YjeE in the presence of ATP and Mg super(2+) resulted in the structure with ADP bound in the P-loop. The ATPase activity of YjeE was confirmed by kinetic measurements. The distribution of conserved residues suggests that the protein may work as a "molecular switch" triggered by ATP hydrolysis. The phylogenetic pattern of YjeE suggests its involvement in cell wall biosynthesis.

Hydrographic and chlorophyll measurements were made at approximately 300 stations, and living zooplankton were collected at 36 stations on the continental shelf (150 m depth) for experimental work. In our experiments, maximum egg production rates (EPR) were observed only for Calanus pacificus and Pseudocalanus mimus, 65.7 and 3.9 eggs fem super(-1) day super(-1) respectively, about 95% of the maximum rates known from published laboratory observations. EPR of all other copepod species (e.g., C. marshallae, Acartia longiremis and Eucalanus californicus) ranged from 3% to 65% of maximum published rates. Fecundity was not significantly related to body weight or temperature, but was significantly correlated with chlorophyll a concentration for all species except Paracalanus parvus and A. longiremis. Copepod biomass and production in on-shelf waters was dominated by female P. mimus andC. marshallae, accounting for 93% of the adult biomass (3.1 mg C m super(-3)) and 81% of the adult production (0.19 mg C m super(-3) day super(-1)). Biomass in the off-shelf environment was dominated by female E. californicus,P. mimus, andC. pacificus, accounting for 95% of the adult biomass (2.2 mg C m super(-3)) and 95% of the adult production (0.08 mg C m super(-3)day super(-1)). Copepodite (C1-C5) production was estimated to be 2.1 mg C m super(-3) day super(-1) (on-shelf waters) and 1.2 mg C m super(-3) day super(-1) (off-shelf water). Total adult + juvenile production averaged 2.3 mg C m super(-3) day super(-1) (on-shelf waters) and 1.3 mg C m super(-3) day super(-1) (off-shelf waters). We compared our measured female weight-specific growth rates to those predicted from the empirical models of copepod growth rates of Huntley and Lopez [Am Nat (1992) 140:201-242] and Hirst and Lampitt [Mar Biol (1998) 132:247-257]. Most of our measured values were lower than those predicted from the equation of Huntley and Lopez. We found good agreement with Hirst and Lampitt for growth rates 0.10 day super(-1). The mismatch with Hirst and Lampitt resulted because some of our species were growing at maximum rates whereas their composite empirical equations predict "global" averages that do not represent maximum growth rates.

As a result, drought indices have slowly evolved during the last two centuries from simplistic approaches based on some measure of rainfall deficiency, to more complex problem-specific models. Indices developed in the late nineteenth and early twentieth century included such measures as percent of normal precipitation over some interval, consecutive days with rain below a given threshold, formulae involving a combination of temperature and precipitation, and models factoring in precipitation deficits over consecutive days. The incorporation of evapotranspiration as a measure of water demand by Thornthwaite led to the landmark development in 1965 by Palmer of a water budget-based drought index that is still widely used. Drought indices developed since the 1960s include the Surface Water Supply Index, which supplements the Palmer Index by integrating snowpack, reservoir storage, streamflow, and precipitation at high elevations; the Keetch-Byram Drought Index, which is used by fire control managers; the Standardized Precipitation Index; and the Vegetation Condition Index, which utilizes global satellite observations of vegetation condition. These models continue to evolve as new data sources become available. The twentieth century concluded with the development of the Drought Monitor tool, which incorporates Palmer's index and several other (post Palmer) indices to provide a universal assessment of drought conditions across the entire United States. By putting the development of these drought indices into a historical perspective, this paper provides a better understanding of the complex Palmer Index and of the nature of measuring drought in general.

AN - 18460766; 5439177 AB - I hypothesize that predation on newborn young represents a seasonal analog to time-lagged predator-prey cycles and can cause directional selection against late birthing. Newborn offspring represent an irruption of vulnerable prey to which predators can respond by adapting their search efforts to find and capture these prey. Those born early would be the 1st to achieve the size or mobility necessary to escape predators. Simple models of predation on moose calves were used to demonstrate how changes in predator efficiency as newborns appear, combined with a short period of offspring vulnerability, would produce selection against late birthing. Of the 9 published studies of mammals, 6 showed evidence of selection against late-born young that could be driven by predation on neonates. If true, this hypothesis has consequences for the way we interpret evidence for 'predator swamping' and optimal birthing periods in mammals and other taxa with synchronous reproduction.

I used age-structured life tables and Leslie matrices based on a prebreeding survey and a yearly time step applied only to females to model the demography of 41 populations from 38 species of sharks representing four orders and nine families. I used Monte Carlo simulation to reflect uncertainty in the estimates of demographic traits and to calculate population statistics and elasticities for these populations; I used correlation analysis to identify the demographic traits that explained most of the variation in population growth rates ( lambda ). The populations I examined fell along a continuum of life-history characteristics that can be linked to elasticity patterns. Sharks characterized by early age at maturity, short lifespan, and large litter size had high lambda values and short generation times, whereas sharks that mature late and have long lifespans and small litters have low lambda values and long generation times. Sharks at the 'fast' end of the spectrum tended to have comparable adult and juvenile survival elasticities, whereas sharks at the 'slow' end of the continuum had high juvenile survival elasticity and low age-zero survival ( or fertility ) elasticity. Ratios of adult survival to fertility elasticities and juvenile survival to fertility elasticities suggest that many of the populations studied do not possess the biological attributes necessary to restore lambda to its original level after moderate levels of exploitation. Elasticity analysis suggests that changes in juvenile survival would have the greatest effect on lambda , and correlation analysis indicates that variation in juvenile survival, age at maturity, and reproduction account for most of the variation in lambda . In general, combined results from elasticity and correlation analyses suggest that research, conservation, and management efforts should focus on these demographic traits.

I review the evolutionary and statistical properties of three popular genetic distances: D sub(S), D sub(A), and theta , using computer simulation of two simple evolutionary histories: an isolation model of population divergence and an equilibrium migration model. The effect of effective population size, mutation rate, and mutation mechanism upon the parametric value between pairs of populations in these models explored, and the unique properties of each distance are described. The effect of these evolutionary parameters on study design is also investigated and similar results are found for each genetic distance in each model of evolution: large sample sizes are warranted when populations are relatively genetically similar; and loci with more alleles produce better estimates of genetic distance.

In contrast, southern rock soleLepidopsetta bilineata females reached 50% maturity at 347 mm L sub(T) and an average age of 9 years. Spawning started in midwinter for northern rock sole and peaked during the spring, while spawning for southern rock sole occurred during the summer. The bottom depth for spawning northern rock sole ranged from 43 to 61 m and averaged 45 m; spawning depth for southern rock sole ranged from 35 to 120 m and averaged 78 m. Both species appeared to develop a single stock of oocytes and to ovulate them in a single spawning. Northern rock sole females grew faster overall (K=0.24) than southern rock sole females (K=0.12) but reached a smaller maximum length (L sub( infinity )=430 mm) than southern rock sole (L sub( infinity )=520mm). Males of both species grew more slowly than females after 5 years of age and reached a smaller maximum length. Copyright 2002 The Fisheries Society of the British Isles.

Poster Paper No. P2.11 N1 - Last updated - 2010-05-03 ER - TY - JOUR T1 - Diving and night-time behavior of long-finned pilot whales in the Ligurian Sea AN - 18457756; 5432524 AB - Pilot whales Globicephala spp. have long been thought to be deep divers, yet little information is available on dive depths. During August 1999 we obtained detailed dive data from suction-cup-attached time-depth recorder/VHF radio tags deployed on 5 long-finned pilot whales G. melas. Pilot whales were tagged for short periods (average 5 h ind. super(-1)) in deep (>2000 m) waters of the Ligurian Sea, off the NW coast of Italy. During the day all 5 whales spent their time in the top 16 m of the water column, and visible surface activities consisted primarily of rest and social behaviors. Tags remained attached after dark on 2 whales and shortly after sunset both whales made several deep dives (max. 360 and 648 m). Velocity on these deep dives was greater than during shallow dives either during the day or at night, suggesting that these deep dives function primarily for foraging. Our results confirm the supposition that long-finned pilot whales can dive deep, particularly within 2 h after sunset, which is the time that vertically migrating prey become more readily available as they move closer to the surface.

After the examination of extensive pesticide concentration data in surface water, tissues, and semipermeable membrane devices (SPMDs), canal contamination seems to be derived from the extensive agricultural production that drains into the C-111 canal. The results of this study indicate that runoff from agricultural processes led to quantifiable pesticide residues in both canal and bay surface water, which occasionally exceeded current water quality criteria. The major pesticide of concern was endosulfan, which was detected at 100% of the sites sampled. Endosulfan exposure did not cause any acute effects in fish and crustaceans deployed in field bioassays. Chronic effects were observed in copepods, clams, and oysters but could not be attributed to endosulfan exposure. The decision to alter the C-111 canal flow and allow increased freshwater flow into the adjacent Everglades National Park may result in discharges of pesticides into the Everglades. Continued monitoring in this area is needed during this change in flow regime.

The DAM assumes that death occurs when the cumulative damage reaches a critical point and was described by a combination of both first-order toxicokinetic and toxicodynamic models. In aqueous exposures, body residues increase in proportion to the water concentration. Damage is assumed to accumulate in proportion to the accumulated residue and damage recovery in proportion to the cumulative damage when damage is reversible. As a result, the toxicity time course, LC sub(50)(t), is determined by both a damage recovery rate and an elimination rate. The constant critical body residue (CBR) and the critical area under the curve (CAUC) models can be derived as two extreme cases from the DAM, and all three models were reanalyzed using a hazard modeling approach. As a result, the critical cumulative damage (D sub(L)) is the determinant of the concentration-time response relationship and not simply the CBR or the CAUC. Finally, from the DAM, two parameters, a damage recovery rate constant k sub(r) and the killing rate k, were estimated and found to be relatively constant for selected PAH.

A constant CBR model is based on the assumption that the body residue for 50% mortality is constant for each PAH across exposure times. With a constant CBR, kinetic parameters determined through kinetic experiments would be similar to those estimated from time series toxicity data. Time-dependent toxicity was investigated using three types of data: time series LC sub(50) data, LT sub(50)(c), and CBR values measured at multiple exposure times for live and dead animals. Kinetic parameters were measured independently. The constant CBR model did not predict the PAH toxicity time course for H. azteca. Since a first-order kinetic model predicted the bioaccumulation of the parent PAH except for naphthalene, this result is not due to a failure to predict the internal dose (body residue). The influence of metabolites on toxicity was negligible except for naphthalene. The LC sub(50) values at multiple exposure times decreased to an incipient lethal concentration after H. azteca reached steady state. Measured CBR values also decreased with increasing exposure time. Thus, the time course of PAH toxicity is determined not only by the bioconcentration kinetics but also by the cumulative toxicity with increasing exposure time. Therefore, time-to-death or hazard models must be developed as a complement to toxicokinetic models to describe and predict the toxicity time course.

AN - 36411582; 9417 AB - PURPOSE: The establishment of the San Francisco Bay National Estuarine Research Reserve in Contra Costa, Marin, and Solano counties, California is proposed. The San Francisco estuary is of major importance ecologically and econmically as the centerpiece of one of the larger metropolitan areas in the country. The estuary lies at the terminus of the Sacramento and San Joaquin river systems which, together, drain almost 40 percent of the land area of California. The estuary covers some 1,600 square miles and occupies the only complete breach of the Coastal Range, a 400-mile-long mountain chain extending from the coast to the Central Valley. A variety of terrestrial, wetland, and aquatic habitats are incorporated into the proposed boundaries of the reserve. Several threatened, endangered, and candidate species of plants and animals occur within the proposed boundaries. In addition to such diversity of natural resources, the reserve would also include significant historical and archaeological sites. Three areas (China Camp State Park, Rush Ranch Open Space Preserve, and Browns Island Regional Shoreline) totaling approximately 4,200 acres would be designated as component sites of the reserve. The lead institution for the reserve would be the Romerg Tiburon Center, an off-campus research and teaching marine laboratory operated by San Francisco State University. The administrative plan would establish an integrated management approach for the San Francisco Bay reserve among the indistutional landholders within the region. The reserve manager would be the principal administrator and would ensure that the policies contained within the reserve management plan were followed. During the first five years of plan implementation, the reserve would hire staff; establish the management, research, and education advisory committees; implement a system-wide monitoring program; implement a graduate fellowship program complete a site profile; develop decision maker workshops and implement the necessary step toward creating the San Francisco Bay Coastal Training Institute; work with reserve partners to establish a coordination plan to either integrate existing volunteer programs or create new volunteer programs a needed; undertake a detailed facilities plan; undertake a stewardship plan, including components for restoration and rehabilitation; and develop outreach and educational materials for target audiences. In addition to the preferred alternative, the final EIS of June 2001 considers a No Action Alternative, alternative reserve boundaries, and alternative management options. A draft supplement provided additional information regarding commercial navigation and socioeconomic issues. POSITIVE IMPACTS: Designation of the reserve components would protect and preserve economically and ecologically valuable and scientifically significant plant, animal, aquatic, and terrestrial resources. Research programs associated with the reserve would contribute to an understanding of estuarine environments and their relation to human populations. Additional recreational and educational opportunities would be provided for the general public. NEGATIVE IMPACTS: NONE. LEGAL MANDATES: Coastal Zone Management Act of 1972 (43 U.S.C. 1241).

Larvae must emigrate from their spawning areas along the continental slope and outer shelf towards shore, in a direction across the prevailing Alaskan Stream. Using a 20 yr time series of data from ichthyoplankton surveys in the Gulf of Alaska, we examine patterns of variability in larval halibut and flounder distributions that may reflect processes resulting in successful recruitment to nursery areas. Several patterns can be observed in these data. Eggs and the smallest-sized larvae are distributed deep in the water column along the outer shelf and slope. Larger larvae tend to be located in the upper water column and farther inshore over the continental shelf. Larger larvae are also associated with deep-sea valleys and troughs that penetrate the shelf. Thus, these topographic features may serve as transport pathways to juvenile nursery grounds. ENSO (El Nino-Southern Oscillation) conditions and warm-year anomalies are linked to recruitment strength of Pacific halibut. Variability in larval transport as related to ENSO and other conditions that enhance onshore advection may play an important role in the recruitment of flatfishes to their nursery grounds. The results of this analysis indicate that larvae of both species are more abundant in coastal areas during El Nino events, and that a higher proportion of larvae are transported inshore during El Nino years.

However, using these stable-isotope ratios to infer dietary changes depends on precise knowledge of turnover rates of carbon and nitrogen. In the present study, carbon and nitrogen turnover rates were determined for recently settled juvenile winter flounder Pseudopleuronectes americanus in the laboratory using naturally occurring stable isotopes as dietary tracers. Flounder were reared at 13 degree C on a diet of rotifers Brachionus plicatilis of known isotopic composition from the time that the larvae began feeding until they reached metamorphosis and began to settle to the benthic habitat. At settlement, the fish were assigned to 1 of 2 temperature treatments (13 and 18 degree C). A subset of fish at each temperature was maintained on rotifers to serve as controls. The remaining fish were switched to a diet of brine shrimp Artemia sp. (known to be isotopically distinct from rotifers) and then sampled systematically over a 16 d period. Temperature had a significant effect on both carbon and nitrogen turnover rates. At 13 degree C, the half-life of carbon was 4.1 d ( plus or minus 0.6), and of nitrogen, 3.9 d ( plus or minus 0.7). At 18 degree C, the half-life of carbon was 2.2 d ( plus or minus 0.3), and of nitrogen, 3.1 d ( plus or minus 0.3). The change in isotopic composition closely followed predictions based entirely on the production of new tissue.

AN - 71986588; 12175034 AB - Application of manure to frozen and/or snow-covered soils of high-latitude, continental climate regions is associated with enhanced P losses to surface water bodies, but the practice is an essential part of most animal farming systems in these regions. Field experiments of the fates of winter-applied manure P are so difficult as to make them essentially impractical, so a mechanistic, modeling approach is required. Central to a mechanistic understanding of manure P snow-melt runoff is knowledge of snowpack disappearance (ablation) as affected by manure application. The objective of this study was to learn how solid manure applied to snow-covered fields modulates the surface energy balance and thereby snow cover ablation. Manure landspreading experiments were conducted in Arlington, WI during the winters of 1998 and 1999. Solid dairy manure was applied on top of snow at a rate of 70 Mg ha(-1) in 1998, and at 45 and 100 Mg ha(-1) in 1999. Results showed that the manure retarded melt, in proportion to the rate applied. The low-albedo manure increased absorption of shortwave radiation compared with snow, but this extra energy was lost in longwave radiation and turbulent flux of sensible and latent heat. These losses result in significant attenuation of melt peaks, retarding snowmelt. Lower snowmelt rates beneath manure may allow more infiltration of meltwater compared with bare snow. This infiltration and attenuated snowmelt runoff may partially mitigate the enhanced likelihood of P runoff from unincorporated winter-spread manure.

Special Studies. Current Population Reports. AN - 62222043; ED467533 AB - Changes in the relationship between educational attainment and work-life earnings over the past 25 years were examined by using data from the Current Population Survey (CPS) to construct synthetic work-life earnings. CPS data collected in March 1998, 1999, and 2000 were analyzed by age, sex, full- or part-time work experience, race, Hispanic origin, and educational attainment groupings. The synthetic estimates were created by using the various study groups' 1-year annual earnings and summing age-specific average earnings for people aged 25-64 years. The resultant totals represent what individuals with the same educational level would expect to earn on average in 1999 dollars in a hypothetical 40-year working life. The following were among the key findings: (1) earnings increase with educational level, with average annual earnings ranging from $18,900 for high school dropouts to $25,900 for high school graduates, $45,400 for college graduates, and $99,300 for workers with professional degrees; (2) earnings differences by educational attainment compound over an individual's lifetime; (3) the educational gap between women and men is narrowing; and (4) educational attainment and work-life earnings vary by sex, race, and Hispanic origin. Detailed information about the study assumptions and limitations and the computational procedure are included. (Contains 10 tables/figures.) (MN) AU - Day, Jennifer Cheeseman AU - Newburger, Eric C.

We reconstructed the monsoon winds for the past 1000 years using fossil Globigerina bulloides abundance in box cores from the Arabian Sea and found that monsoon wind strength increased during the past four centuries as the Northern Hemisphere warmed. We infer that the observed link between Eurasian snow cover and the southwest monsoon persists on a centennial scale. Alternatively, the forcing implicated in the warming trend (volcanic aerosols, solar output, and greenhouse gases) may directly affect the monsoon. Either interpretation is consistent with the hypothesis that the southwest monsoon strength will increase during the coming century as greenhouse gas concentrations continue to rise and northern latitudes continue to warm.

This problem can lead to an artificial leakage of the error estimates of short-scale (high degree) spherical harmonic functions into long wavelength (low wave number) Fourier functions. A similar effect can be seen in an idealized box inverse model constrained by additional sea-surface topography data of low, medium, and high resolution: When more information is added in the form of additional smaller scales, the error of a transport estimate eventually increases. Including the large geoid omission errors associated with smaller scales in a box inverse model of the Southern Ocean increases the posterior errors of transport estimates over those of a model that does not include the geoid omission error. The authors juxtapose two different ways of estimating the geoid errors to demonstrate the effect that the omission error might have on the long scales. Accounting for the geoid omission error should be the topic of further research. (Mod. auth. abstr.)

Eight of forty-one optical/temperature profiles contain hydrothermal plume characteristics that indicate firm evidence for two active vent sites and tentative evidence for as many as three others. Fossil hydrothermal material was recovered in 6 of the 38 dredge hauls and includes an occurrence of partially oxidized sulfide breccias, four deposits of sepiolite and silica, as well as Mn-oxide and nontronite cemented breccias. The massive sulfide deposit likely developed during mixing of upwelling hot fluids with cold seawater within a shallow permeable fault breccia along a deep-seated normal fault bounding the southern rift valley wall. Silica and sepiolite deposits were found mostly on the rift valley walls and likely formed during low- to moderate-temperature ultramafic-hosted hydrothermal activity. The abundance of hydrothermal material and the frequency of localized hydrothermal activity is remarkable because the mantle upwelling and magma supply rates, and hence the magmatic heat input, along this section of the SWIR are lower than on any other explored segment of the global mid-ocean ridge system. This observation suggests that high mantle upwelling and magma supply rates are not required to drive mid-ocean ridge hydrothermal systems and that a close relationship between magmatic heat input and hydrothermal activity may not be established at the ultra-slow end of the ridge spreading spectrum. The frequency and distribution of hydrothermal activity in the study area may reflect a largely tectonic control on fluid circulation, with hydrothermal vent sites being preferentially associated with long-lived faults that provide fluid pathways. Our results suggest the contribution of magma-starved ridge segments to the global ocean-lithosphere geochemical budget is potentially much larger than previously thought.

AN - 36408824; 9401 AB - PURPOSE: The construction of a new segment of U.S. 101 to provide a bypass of the city of Willits in Mendocino County, California is proposed. The facility is an important route for interstate and interregional travel and is considered the economic lifeline of California's North Coast. It is the principal arterial route for the movement of people and goods between the San Francisco Bay area and the greater Eureak-Arcata area. Travel times and transportation costs along U.S. 101 are high. Travel times and costs are exacerbated by congestion-related delays and delays caused by facility type at Willits, where U.S. 101 passes through developed areas on surface streets. Five alternatives, including a No Action Alternative, are considered in this draft EIS. Three of the four action alternatives would involve construction of a new freeway segment east of Willits; the fourth alternative would provide a western bypass. The alternatives vary in length from 5.6 miles to 9.2 miles. Estimated capital costs for the build alternatives range from $128 million to $301 million. POSITIVE IMPACTS: The project would improve the safety and efficiency of traffic movements on U.S. 101 in and around Willits [NEG]Rights-of-way development would result in the loss of 15.1 to 129.1 acres of wetlands and up to 713 acres of prime farmland and the displacement of up to 114 residences and three businesses. Two special status plant species, Baker's medowfoam and glandular western flax, would be affected, as would habitat for yellow warbler, yellow-breasted chat, little willow flycatcher, raptors, northwestern pond turtle, foothill yellow-legged frog, spotted owl, tree volecoho salmon, fall-run chinook salmon, and steelhead trout. Under one alternative, the facility would follow an alignment susceptible to landslides. Under another alternative, hazardous waste site cleanup would be necessary. Relocation of a stream segment could be required.

In the next 10 years, additional natural matrix SRMs were developed including air and diesel particulate matter, petroleum crude oil, coal tar, sediment, and mussel tissue. The SRMs represented the "first generation" of natural matrix SRMs for the determination of PACs. The SRMs had "certified" values for only 5 to 12 PACs; however, their development established the foundation for the implementation of the "two or more independent analytical techniques" approach for certification of individual PACs in environmental matrices. The requirement for use of different analytical techniques spurred the development of both gas chromatography (GC) and liquid chromatography (LC) approaches for the determination of PACs. Since the mid- 1990s, the "second generation" of natural matrix SRMs has been issued by NIST with certified values for over 20 PACs in each material. The greater number of certified values in these SRMs was the result of the combination of measurements using reversed-phase LC with fluorescence detection, multidimensional LC, and GC with mass spectrometric detection using two or more stationary phases with different selectivity for polycyclic aromatic hydrocarbon (PAH) separations. This article discusses the significant developments in analytical methods and chromatographic separation of PAHs during the past 20 years that have resulted in the certification of over 25 SRMs, which are now used worldwide for the validation of analytical methods for the measurement of PACs in environmental matrices.

It is part of the Caribbean Islands National Wildlife Refuge, under the jurisdiction of the US Fish and Wildlife Service. We conducted a quantitative assessment of Navassa's coral reef fishes and benthic habitat, in order to assist with the development of conservation plan for the island. The shallow reefs of Navassa (< 23m) have high live coral cover (range 20-26.1%), high degree of architectural complexity (rugosity index range 1.4-1.9), and moderate abundance of the keystone grazing urchin, Diadema antillarum, at all sites (mean 2.9 plus or minus 0.9 per 30 m super(2)). Despite its remoteness, an unregulated, artisanal fishery (primarily using traps and hook and line) carried out by Haitians is the primary mode of human impact on Navassa reefs. Even so, reef fish communities exhibit high density (range 97-140 fish per 60 m super(2)) and retain representation by large snapper, grouper and herbivores, which are mostly lacking in nearby Caribbean locations with high fishing pressure. Thus, Navassa reefs appear to be trophically intact with fish populations relatively "unexploited," presenting a conservation challenge and a research opportunity. The regulation and conservation of the fishery will be difficult, due to the international nature of the situation. However, given the apparently small impact that artisanal fisheries have yet had on its reef communities, Navassa presents a possibly unique opportunity to study the ecological functioning of a relatively trophically intact Caribbean reef, and represents a strong imperative for conservation, monitoring, and research.

Although they have often been considered to be rare members of deep-sea communities, recent trawling has shown that the relative abundance of some cirrates, especially opisthoteuthids, may be locally or regionally high (e.g., Boyle et al., 1998). Cirrates also are presumed to be primitive, morphologically similar to ancestral octopods (Young et al., 1998), although recent observations indicate unexpected adaptations such as bioluminescence (Johnsen et al., 1999) and possibly diverse feeding modes (Vecchione and Young, 1997). Therefore, knowledge of cirrates may contribute substantially to understanding cephalopod evolution as well as deep-sea biology and ecology. However, because they are fragile, the condition of specimens collected up until the past decade generally has been very poor, and our knowledge of the group is rudimentary. New methods, such as videotapes recorded in-situ and gentle collection by submersibles, have allowed substantial new observations and renewed interest in the group. Participation in the cirrate workshop was by invitation only and was limited to researchers actively working on cirrates. The participants focussed their attention on the following topics: (1) taxonomy and systematics, (2) behavior and functional anatomy, (3) biology, growth, and feeding, and (4) distribution and abundance. One tool that proved to be especially useful throughout these deliberations was a summary of the current status of cirrate nomenclature, prepared for the workshop by Michael Sweeney of the Smithsonian Institution, who unfortunately was unable to travel to Scotland. We present an abridged version of the summary so that it can continue to be of use to researchers who are interested in these fascinating but difficult cephalopods.

Coastal conditions were determined shipboard during two sets of five cross-shelf transects conducted 4 d apart, and instrument moorings simultaneously recorded wind velocity in the nearshore zone and biophysical water properties within Willapa Bay. The results demonstrate that estuarine physical oceanography and chlorophyll concentrations were determined by processes occurring in the nearshore ocean, and these in turn were forced by variation in wind stress. At the start of the study period, southerly winds produced downwelling conditions that forced the Columbia River plume against the coast, and low salinity water was advected into Willapa Bay. This water was relatively low in chlorophyll (<2 mg m super(-3)). As the winds switched to an equatorward direction, coastal upwelling ensued and the Columbia plume was replaced by cold, salty water nearshore. A phytoplankton bloom exceeding l0 mg m super(-3) was generated on the shelf with its core located 10 to 40 km from the estuarine mouth. The upwelling-favorable winds then relaxed, and the bloom was apparently advected across the shelf to the coast and subsequently into Willapa Bay, where instruments recorded pulses of chlorophyll entering the estuary on flood tides. Weak downwelling conditions were prevalent for the next several days, and the Columbia River plume returned to the coast where it mixed with the chlorophyll-enriched waters in the nearshore before entering the estuary. These results demonstrate that primary productivity generated in coastal waters can be transported to estuaries, where it is likely an important yet episodic food source for estuarine organisms.

Larval recruitment in New Jersey extended for 9 months beginning in October but was discontinuous and was punctuated by periods of no catch that were associated with low water temperatures. In North Carolina, recruitment was continuous for 5-6 months beginning in November. Total yearly larval density in North Carolina was higher (15-39 times ) than in New Jersey for each of the 3 years. Larvae collected in North Carolina generally grew faster than larvae collected in New Jersey and were, on average, older and larger. Birthdate distributions (back-calculated from sagittal otolith ages) overlapped between sites and included many larvae that were spawned in winter. Early spawned (through October) larvae caught in the New Jersey estuary were probably spawned off New Jersey. Larvae spawned later (November-April) and collected in the same estuary were probably from south of Cape Hatteras because only there are winter water temperatures warm enough ( greater than or equal to 16 degree C) to allow spawning and larval development. The percentage contribution of these late-spawned larvae from south of Cape Hatteras were an important, but variable fraction (10% in 1992-93 to 87% in 1989-90) of the total number of larvae recruited to this New Jersey estuary. Thus, this study provides evidence that some B. tyrannus spawned south of Cape Hatteras may reach New Jersey estuarine nurseries.

Herein, I develop a trade-off model used to predict the timing of vertical migration of zooplankton. The model is based on "Gilliam's rule" - the notion that animals will select habitats that minimize the ratio of mortality risk/energy gain - and incorporates light- and size-dependent vulnerability to visual predators. The model predicts that smaller, less vulnerable prey should ascend into food-rich surface waters earlier and descend later than larger, more conspicuous organisms over a wide range of conditions. The model has been parameterized for a population of Euphausia pacifica in Saanich Inlet, British Columbia, and predicts that 7-mm (larval) animals will ascend/descend similar to 35 min earlier/later than more conspicuous 24-mm adults. These predictions are consistent with acoustic observations of the timing of DVM in this population. The proposed mechanism for size-dependent timing of DVM is based on the potential for increased energy gain in surface waters and diel changes in vulnerability to size-selective predators. These conditions prevail in both freshwater and marine pelagic environments, and size-dependent DVM is likely to be widespread in zooplankton.

The analysis was based on the Peng-Robinson equation of state and the extended corresponding-states method. Jet-A fuel was treated as a pseudo-single-component fluid and a binary mixture. The calculated fuel/air mass ratios from the binary-mixture model followed the trend observed in previous measurements more closely than those from the pseudo-single-component model. The calculated results also demonstrated that for a given amount of fuel, increasing the tank temperature could potentially cause an initially non-flammable fuel/air vapor in the ullage to become flammable.

The culture techniques traditionally employed were developed by the local state, and federal enhancement agencies. These techniques utilize carbon dechlorination of municipal water, flowing once through fish rearing tanks, then to the sewer (single pass). Previous research efforts at the NWFSC, such as rearing endangered species, fish physiology, nutrition, toxicology and improvement of fish husbandry practices, have been conducted exclusively with single pass water. Increasing demands placed on the region's freshwater resources, and the increasing dollar value of municipal water called into question the suitability of single pass water use. In 1991, Seattle experienced a drought which resulted in water restrictions and higher water costs. During this time, the NWFSC was identified as one of the top twelve water users in Seattle. The mission of the National Marine Fisheries Service includes the wise use of limited natural resources and sound environmental stewardship (NOAA 1995-2005 Strategic Plan); the continued use of single pass water for fish culture is counter to that mission.

SEM analysis of whale feces containing DA, collected from krill-feeding whales, revealed the presence of diatom frustules identified as Pseudo-nitzschia australis, a known DA producer. Humpback whales were observed feeding on anchovies and sardines that contained DA at levels ranging from 75 to 444 mu g DA g super(-1) viscera. DA contamination of whale feces and fish occurred only during blooms of toxic Pseudo-nitzschia. Additionally, several novel fish species collected during a toxic diatom bloom were tested for DA. Fish as diverse as benthic sanddabs and pelagic albacore were found to contain the neurotoxin, suggesting that DA permeates benthic as well as pelagic communities.

AN - 14661240; 10641500 AB - The sizes of stranded sea turtles (loggerhead, green, and Kemp's ridley) were compared with the size of turtle excluder devices developed for shrimp trawl nets on ships operating in southeastern U.S. waters. Shrimp trawling has been blamed as the largest source of human mortality of many of the sea turtle species, which have low population levels compared with historic levels, and which are protected. A large proportion of stranded loggerhead turtles (33%-47%) and a small proportion of stranded green turtles (1%-7%) are too large to fit through the minimum size excluder device openings. Continued high mortality of sea turtles, particularly northern subpopulations of loggerhead turtles, from bottom trawling needs to be addressed further.

Herring populations have recovered from extensive overfishing in the 1960s and 70s. Three distinct but seasonally overlapping components in the herring population are identified and discussed. The overall range contracted as herring biomass declined in the late 1970s, then expanded in the 1990s with herring recovery. Herring currently are at a high level of abundance and biomass, as all three components have recovered to pre-1960s abundance levels. Herring from adjacent components (most likely Gulf of Maine spawners) probably recolonized the Georges Bank region after its severe decline.

In place of inadequate tagging technology and sample sizes, genetic markers found in mitochondrial DNA can help predict the origin of juvenile turtles. Mixed stock analysis was applied to determine which nesting populations were contributing to a foraging aggregation of juvenile loggerhead sea turtles off the coast of Hutchinson Island, FL. At least three different western Atlantic subpopulations (from south Florida, Mexico, and northeast Florida/North Carolina) were found to contribute to the foraging group. Such multinational genetic demographies present additional complications to loggerhead sea turtle conservation and management.

Average catch per unit effort (CPUE) of all groundfish species increased with depth, peaking in the continental shelf break region (150-200 m). Species richness and diversity both peaked at about 200-300 m depth. The western part of the gulf had higher CPUE and lower species richness and diversity compared with the eastern part. Areas within the gulf having the highest richness values are listed. Total CPUE differed significantly among survey years, with total groundfish biomass increasing by 40% over the study period. Multivariate analysis of 72 groundfish species revealed strong gradients in species composition with depth and from east to west. A weak shift in species composition over time was associated with increased frequency of occurrence and CPUE of at least eight taxa, and with decreased frequency of occurrence and CPUE in several sculpin species. The ecological and management implications of these findings are discussed.

Shad restoration projects are underway to restock depleted spawning areas. In addition, the Chesapeake Bay stock of striped bass has rebounded after severe declines in the 1970s and 80s, following successful management. Shad spawning reaches in the Mattaponi and Pamunkey Rivers are described. Surveys were conducted to determine if striped bass also spawn in the shad spawning areas. Some temporal and spatial overlap occurs in the spawning distributions of shad and striped bass, but the primary spawning grounds of these species are disjunct, perhaps because of trophic interactions (e.g., predation and competition). Spawning areas used likely will expand or contract in response to shad population size shifts. If restoration efforts are successful, the availability of suitable spawning areas may become the limiting factor in population growth.

These are calculated based on stochastic population dynamics models. Statistical distributions of stock-rebuilding time isopleths are characterized under different assumptions about uncertainty and process error. This approach is applied to analyze rebuilding times for two stocks (California Bight cowcod rockfish and Georges Bank yellowtail flounder), which have different life histories, fishing mortality levels, and autocorrelation in production process errors. In these cases, stock rebuilding time distributions generally were variable and right-skewed, suggesting that rebuilding may take less or substantially more time than previously expected. The use of stock-rebuilding isopleths from deterministic and stochastic models to design, evaluate, and monitor the progress of rebuilding plans also is discussed.

AN - 36425341; 9396 AB - PURPOSE: The issuance of permits to discharge approximately 2.5 million cubic yards of fill material into waters of the United States, including wetlands, is proposed to create dry land to allow for the construction of a mixed-use commercial development project adjacent to the Hackensack River within the Hackensack Meadowlands District in the boroughs of Carlstadt and Moonachie and the township of South Hackensack, Bergen County New Jersey. Empire Ltd seeks the permit to implement a 587-acre project, to be known as Meadowlands Mills that would result in the development of a super-regional retail/entertainment center, office space, hotel space, a mass transit facility, warehouse/distribution facilities, and associated parking structures and roadways. The development would consist of five integrated components, including 2.45 million square feet of retail/entertainment space, 2.2 million square feet of office space, 1,000 hotel rooms with a conference center encompassing 799,000 square feet, 150,000 square feet of warehouse space, and 13,000 square feet of mass transit facilities. The project would be implemented in cooperation with The Mills Corporation of Arlington, Virginia. A No Action Alternative and three development alternatives, including Empire's proposed alternative, are considered in this final EIS. As proposed by Empire, the project would occupy a 592-acre site, known as the Empire Tract and two acres of land adjoining New Jersey Turnpike Authority property. Three development footprint alternatives, alternative sites, and a No Action Alternative are considered in detail in this draft EIS. Two footprint alternatives would involve development of the commercially zoned site on a 90.5-acre footprint. A 144-acre wetland fill alternative would include the applicant's computation of 53.5 acres needed for water control infrastructure and transportation components, in addition to the 90.5 acres. A 134-acre wetland fill alternative would realize the various components of the project through a modified site layout, resulting in a smaller development footprint than the 144-acre alternative. Empire has proposed a wetland mitigation plan, which would entail enhancement of 335 acres of wetland and preservation of 45 acres of wetland on the Empire Tract. The wetlands enhancement component would involve removal of common reed grasses, followed by regrading and replanting these areas to create shallow water, an emergent marsh, and forested, scrub-shrub and wet meadow habitats. POSITIVE IMPACTS: The development would provide an expanded employment base in the area during both construction and operation. Sales and income taxes to municipal, county, state, and federal governments Wetlands mitigation would result in an increase in plant species and habitat diversity designed to improve habitat quality and offset impacts to wildlife. Eleven state-listed threatened or endangered species could benefit. Waterfowl, migratory shorebirds, wading birds and, possibly, other species could benefit via the regional effects of wetlands mitigation and through the reintroduction of tidal flow to brackish wetlands. NEGATIVE IMPACTS: Regardless of the alternative selected, the development would result in placement of fill in 134 acres of waters, including wetlands, further fragment existing common reed wetland habitat in the Hackensack Meadowlands. The site would be located on the western edge of a larger block of wetlands that would be reduced. Regional habitat of certain endangered species, including the northern harrier, could suffer from fragmentation. The development would increase vehicular traffic in the area significantly, though appropriate infrastructure would be available to accommodate this increase. The average wastewater flow to flow to the Bergen County treatment facility would increase by 0.77 million gallons per day (mgd) to a level of 85 mgd; the facility has a treatment capacity of 109 mgd.

POSITIVE IMPACTS: The development would provide an expanded employment base in the area during both construction and operation. Sales and income taxes to municipal, county, state, and federal governments Wetlands mitigation would result in an increase in plant species and habitat diversity designed to improve habitat quality and offset impacts to wildlife. Eleven state-listed threatened or endangered species could benefit. Waterfowl, migratory shorebirds, wading birds and, possibly, other species could benefit via the regional effects of wetlands mitigation and through the reintroduction of tidal flow to brackish wetlands. NEGATIVE IMPACTS: Regardless of the alternative selected, the development would result in placement of fill in 134 acres of waters, including wetlands, further fragment existing common reed wetland habitat in the Hackensack Meadowlands. The site would be located on the western edge of a larger block of wetlands that would be reduced. Regional habitat of certain endangered species, including the northern harrier, could suffer from fragmentation. The development would increase vehicular traffic in the area significantly, though appropriate infrastructure would be available to accommodate this increase. The average wastewater flow to flow to the Bergen County treatment facility would increase by 0.77 million gallons per day (mgd) to a level of 85 mgd; the facility has a treatment capacity of 109 mgd.

AN - 36378426; 9396-020282_0004 AB - PURPOSE: The issuance of permits to discharge approximately 2.5 million cubic yards of fill material into waters of the United States, including wetlands, is proposed to create dry land to allow for the construction of a mixed-use commercial development project adjacent to the Hackensack River within the Hackensack Meadowlands District in the boroughs of Carlstadt and Moonachie and the township of South Hackensack, Bergen County New Jersey. Empire Ltd seeks the permit to implement a 587-acre project, to be known as Meadowlands Mills that would result in the development of a super-regional retail/entertainment center, office space, hotel space, a mass transit facility, warehouse/distribution facilities, and associated parking structures and roadways. The development would consist of five integrated components, including 2.45 million square feet of retail/entertainment space, 2.2 million square feet of office space, 1,000 hotel rooms with a conference center encompassing 799,000 square feet, 150,000 square feet of warehouse space, and 13,000 square feet of mass transit facilities. The project would be implemented in cooperation with The Mills Corporation of Arlington, Virginia. A No Action Alternative and three development alternatives, including Empire's proposed alternative, are considered in this final EIS. As proposed by Empire, the project would occupy a 592-acre site, known as the Empire Tract and two acres of land adjoining New Jersey Turnpike Authority property. Three development footprint alternatives, alternative sites, and a No Action Alternative are considered in detail in this draft EIS. Two footprint alternatives would involve development of the commercially zoned site on a 90.5-acre footprint. A 144-acre wetland fill alternative would include the applicant's computation of 53.5 acres needed for water control infrastructure and transportation components, in addition to the 90.5 acres.

Adults were collected off the coasts of North Carolina, Georgia and Florida, and juveniles were collected along the shore of Long Island, New York. They have also been found around Bermuda. Lionfish are indigenous to tropical waters of the western Pacific and their occurrence along the east coast of the United States represents a human-induced introduction. Distribution of adults suggests lionfish are surviving in the western Atlantic and capture of juveniles provides putative evidence of reproduction. The most likely pathway of introduction is aquarium releases, but introduction via ballast water cannot be ruled out. The ecosystem of the southeastern United States continental shelf is already undergoing change: reef fish communities are becoming more tropical and many fish species are overfished. These ongoing changes, along with limited information regarding the biology of P. volitans, make predictions of long-term effects of the introduction difficult. This discovery represents the first, apparently successful introduction, of a marine fish from the western Pacific to Atlantic coastal waters of the United States.

Pre-mortality sea urchin densities were up to 5 ind. m super(-2) and the large scale decline of D. antillarum is considered to be 1 factor affecting community dynamics of Florida Keys reefs. During 1999-2000, we surveyed 125 sites using a stratified random sampling design in shallow-water coral reef and hard-bottom habitats. Strip transects were sampled to assess density, habitat utilization and size structure patterns among habitat types, regional sectors and between fished and protected areas. Nearly 17 yr after the mass mortality, D. antillarum has not recovered to pre-1983 levels, with current densities no greater than 0.05 ind. m super(-2), and small test sizes (1 to 2 cm) dominate. Other sea urchins such as Eucidaris tribuloides (Lamarck) and Echinometra viridis Agassiz show density and habitat distribution patterns similar to historical observations.

AN - 36413406; 9356 AB - PURPOSE: The implementation of a coastal zone management plan for the Indiana shoreline of Lake Michigan and associated lands and waters is proposed. The lakeward boundary of the area consists of the jurisdictional borders within the lake that Indiana shares with Illinois and Michigan. The inland boundary includes those areas that drain into Indiana's portion of the lake to the state border with Illinois and the LaPorte County line. The inland coastal program boundary includes all shorelands subject to erosion or flooding, estuarine areas and wetlands, and other areas, the use of which may directly and significantly affect Lake Michigan waters. The coastal program area encompasses 604 square miles of land and approximately 241 square miles of Lake Michigan. The area covers the northern portions of Lake, Porter, and LaPorte counties. Approval of the plan would allow program administrative grants to be awarded by the National Oceanic and Atmospheric Administration to the state and would require that federal actions within the affected areas be consistent with the program. The comprehensive program would consist of numerous rules on diverse management issues that are administered under Indiana law. The program would cover coastal hazards, water quality, water quantity, natural areas, fisheries, wildlife, native and exotic species, recreation, coastal access, cultural resources, economic development, pollution prevention and related waste management issues, air quality, and property rights. The program recognizes areas that have unique qualities that either make them vulnerable or increase the competition for their use; these areas are designated as "coastal areas of significance". Federal alternatives to program approval include delaying or denying approval under the circumstances that certain requirements of the Coastal Zone Management Act have not been met. POSITIVE IMPACTS: The plan would promote the beneficial use of coastal resources, prevent their impairment, and manage major activities that substantially affect numerous coastal resources. The program would enhance decision-making processes used for determining the appropriateness of actions in the coastal zone.

AN - 36416142; 9344 AB - PURPOSE: The widening of a 4.6-mile two-lane section of State Route (SR) 149 to a four-lane expressway between SR 70 and SR 99 and the construction of freeway-to-freeway interchanges at the SR 70 and SR 99 intersections in Butte County, California is proposed. The highway, which provides a connecting link between the four-lane section of SR 70 north of Oroville and the four-lane-section of SR 9 south of Chico, serves inter-regional and local commuter traffic. The capacity of the roadway and its poor physical condition have lead to congestion and safety problems. Four alternatives, including a No Action Alternative and three build alternatives, are considered in this draft EIS. Under the build alternatives, improvements would include provision of two additional 12-foot lanes, a 60- to 72-foot median, 10-foot outside shoulders, and a five-foot median shoulder for the full length of the study corridor. In addition, the project would include realignment of SR 70 between SR 149 and SR 191, rehabilitation of the existing SR 149 roadway, construction of the abovementioned freeway-to-freeway interchanges, reconstruction of the SR 70/191 intersection, and construction of driveway access roads. Action Alternative 1 would widen the highway to the south, while Action Alternative 2 would widen the highway to the north. Alternative 3 would realign the highway to avoid habitat for the endangered Butte County Meadowfoam. Project costs range from $80 million to $90 million. POSITIVE IMPACTS: The project would improve safety, provide concept level of service C for the year 2020, and provide an inter-regional transportation facility between Oroville and Chico. NEGATIVE IMPACTS: Depending on the action alternative selected, rights-of-way requirements for the project would result in the displacement of four residences, three to four businesses, three acres of farmland, 24 parcels of Williamson Act land, 29.33 to 33.58 acres of fairy and tadpole shrimp habitat, 5.56 to 7.29 acres of vernal pool and swale habitat, and up to 0.57 acres of Butte County Meadofoam habitat. Traffic-generated noise would exceed federal standards in the vicinity of three noise-sensitive receptors. The highway would traverse two floodplains.

AN - 71722817; 12031895 AB - Free radicals are produced in cells by cellular metabolism and by exogenous agents. These species react with biomolecules in cells, including DNA. The resulting damage to DNA, which is also called oxidative damage to DNA, is implicated in mutagenesis, carcinogenesis, and aging. Mechanisms of damage involve abstractions and addition reactions by free radicals leading to carbon-centered sugar radicals and OH- or H-adduct radicals of heterocyclic bases. Further reactions of these radicals yield numerous products. Various analytical techniques exist for the measurement of oxidative damage to DNA. Techniques that employ gas chromatography (GC) or liquid chromatography (LC) with mass spectrometry (MS) simultaneously measure numerous products, and provide positive identification and accurate quantification. The measurement of multiple products avoids misleading conclusions that might be drawn from the measurement of a single product, because product levels vary depending on reaction conditions and the redox status of cells. In the past, GC/MS was used for the measurement of modified sugar and bases, and DNA-protein cross-links. Recently, methodologies using LC/tandem MS (LC/MS/MS) and LC/MS techniques were introduced for the measurement of modified nucleosides. Artifacts might occur with the use of any of the measurement techniques. The use of proper experimental conditions might avoid artifactual formation of products in DNA. This article reviews mechanistic aspects of oxidative damage to DNA and recent developments in the measurement of this type of damage using chromatographic and mass spectrometric techniques.

This paper focuses on the chemistry of the major and minor elements in the fluids that resulted from this interaction. The elemental enrichments in these fluids are dominated by three processes: (1) evaporation of water from seawater, which creates solutions enriched in the major elements found in seawater, (2) congruent dissolution of the basalt glass matrix, which is limited by the solubility of some of the elements in seawater, and (3) removal of volatile phases from the lava on contact with seawater.Using a simple model of volatile emanation (using published emanation coefficients) and congruent dissolution, we are able to explain the concentrations observed for the majority of elements in precipitation from the steam plume at the shoreline lava entry and in water allowed to interact with molten lava in controlled experiments. Fe, Al, Ti, and some of the rare earth elements (REEs) in precipitation samples from the steam plume at the lava entry were >10,000-times enriched over their ambient seawater concentrations, suggesting that these elements may be useful for identifying submarine eruptions. The flux of elements from the Kilauea ocean lava entry is greater than that from a typical midocean ridge hydrothermal vent field for Al, Cd, Co, and the REEs, whereas the opposite is true for the remainder of the elements studied.

The climate parameters identified that relate to the present-day pollen distribution of the nine most important pollen types (Nothofagus dombeyi-type, Nothofagus obliqua-type, Podocarpus, Weinmannia, Caldcluvia/Eucryphia-type, Cupressaceae, Myrtaceae, Misodendrum and steppe-types) are summer precipitation, summer and winter temperatures. Using the modern pollen/climate data set, three fossil pollen records (Mallin Aguado and Lago Moreno, east of the Andes, and Caunahue, west of the Andes) are interpreted in terms of these three seasonal climate parameters. Despite intervals of no-analog fossil pollen assemblages, the reconstruction shows similar climate trends on both sides of the Andes during the last 21 000 cal. yr BP (17 000 yr BP), with summer precipitation as low or markedly lower than today prior to 17 000 cal. yr BP (14 500 yr BP), as high or higher than today between 15 000 and 12 500 cal. yr BP (12 500 and 10 500 yr BP), and again lower than today between 12 500 and 8000 cal. yr BP (10 500 and 7200 yr BP). Summer and winter temperatures were low (or high) when summer precipitation was high (or low).

The earlier stage of spreading separated Northwind Ridge from the Arctic Islands, and rotated it 35 degrees clockwise, during the Berriasian (?) and Valanginian. The younger stage, well expressed in low-amplitude magnetic anomalies that radiate northward from a pole in the lower Mackenzie Valley, is Hauterivian to earliest Aptian. . The axis of these anomalies coincides with a narrow linear negative gravity anomaly that is typical of extinct spreading centers, and a graben recorded in seismic reflection data. Sediment from the Mackenzie River deposited a clastic wedge (oceanic layer 1) in the Canada Basin that is 14 km thick at the Mackenzie Delta and thins to 5 to 7 km beneath the western part of the basin. Underlying layer 1 are well-bedded strata of erratic thickness ranging up to 1 km that contain strong seismic reflectors and intrusive bodies. We interpret this unit, which contains numerous normal faults older than layer 1, to be oceanic layer 2A. Northwind Escarpment, which bounds Canada Basin on the west, is a sediment-starved, non-volcanic margin containing grabens and a belt of transitional crust as much as 100 km wide that stands 1 to 3 km higher than oceanic crust in the central Canada Basin. In these and other respects it resembles the classic sediment-starved nonvolcanic passive continental margin off western Iberia.

Access to reliable information on the structure of crystalline materials helps researchers concentrate experimental work in directions that optimize the discovery process. The Inorganic Crystal Structure Database (ICSD) is a comprehensive collection of more than 60 000 crystal structure entries for inorganic materials and is produced cooperatively by Fachinformationszentrum Karlsruhe (FIZ), Germany, and the US National Institute of Standards and Technology (NIST). The ICSD is disseminated in computerized formats with scientific software tools to exploit the content of the database. Features of a new Windows-based graphical user interface for the ICSD are outlined, together with directions for future development in support of materials research and design.

Land temperatures were 0.75 degrees C (1.35 degrees F) above average and ocean temperatures were 0.40 degrees C (0.72 degrees F) above the 1880-2000 mean. This ranks them as the second and third warmest on record, respectively. The Northern Hemisphere temperature continued to average near record levels in 2001 at 0.60 degrees C (1.08 degrees F) above the long-term average. The Southern Hemisphere also reflects the globally warmer conditions, with a positive anomaly of 0.43 degrees C (0.77 degrees F). Annual anomalies in excess of 1.0 degrees C (1.8 degrees F) were widespread across North America and much of Europe and the Middle East, while significantly cooler than average conditions were confined to western Australia, the northeast and northwest Pacific Ocean, and the far southeastern region of the Pacific, near coastal Chile. Although no hurricanes made landfall in the United States for the second consecutive year, it was nonetheless an extremely active Atlantic hurricane season, the fourth most active on record. Tropical Storm Allison became the costliest tropical storm on record when it caused approximately $5 billion worth of damage in the southern and southeastern United States. The season was slow to start but quickly escalated in the last three months of the season and it was the first time in recorded history that three hurricanes formed in the Atlantic in the month of November. The long-running La Nina episode finally came to an end in 2001. The La Nina, which began in mid-1998 persisted through the first half of the year but gave way to neutral ENSO conditions for the latter half. Other notable events in 2001 include extreme cold and snow in Siberia during the 2000-01 boreal winter, ongoing drought in the Middle East and central Asia, drought in Central America and Brazil, near-record flooding in central/eastern Europe, an extremely wet austral spring in northeastern Argentina, severe moisture deficits in some regions of the United States, and the driest year on record in parts of western Australia.

Estimates produced by Ahmed and Robinson (1994) and Oosse (1998) were recreated and evaluated by age, sex, race, and Hispanic origin to determine if the estimated flows were realistic. In addition, an attempt was made to create new foreign-born emigration estimates for the 1990 and 2000 decade using the preliminary results from Census 2000. Based on recreation and evaluation efforts, Ahmed and Robinson and Oosse estimates appear sound and represent the most recent and most reliable data on foreign-born emigration available. Future research is needed to evaluate the application of a residual method to estimate foreign-born emigration. In addition, efforts will focus on creating new estimates using alternative methodologies and data sources.

Marine protected areas, as defined in the executive order, include "any area of the marine environment that has been reserved by Federal, State, territorial, Tribal, or local laws or regulations to provide lasting protection for part or all of the natural and cultural resources therein." The concept of marine protected areas is currently under scrutiny by members of the U.S. Congress, coastal natural resource management agencies, special interest stakeholder groups, and the public. As a surrogate for public opinion polls, a media content analysis was performed for U.S. news stories related to marine protected areas. The analysis examined more than 25,000 on-line newspaper, news wire, and broadcast media stories from 1995 to 2001 for expressions of four broad categories of benefits and values associated with marine protected areas, expressions of favorable and unfavorable attitudes associated with marine protected areas, and stakeholder groups involved in the discussion. Ecological benefits and values were expressed more often than social, recreational, and commercial benefits and values. Favorable attitudes were expressed more frequently than unfavorable attitudes. During the period of analysis, a gradual upward trend was found in frequencies of expressions of ecological, social, recreational, and commercial benefits and values. A gradual upward trend was found for relative frequency of favorable attitudes and a gradual downward trend for unfavorable attitudes. The stakeholders mentioned in connection to marine protected areas, in order of frequency, were government, nongovernmental groups, the public, industry, and academia. This presentation will describe the study methods and findings of the analysis and offer management implications and suggestions for further research.

This new awareness has led to changes within local, state, federal, and international natural resource management. This session will seek to stimulate discussion about the nature and characteristics of change in coastal landscapes, the resultant challenges associated with change, and the steps being taken by the coastal management community to address these challenges at multiple levels. Presenters will highlight changes occurring in coastal landscapes, describe resultant human dimensions challenges facing coastal management, and discuss methods underway within different natural resource management and policy-making entities to incorporate social science methods into management.

The results for 2030 show increases in near-surface air temperature of 1-2 degree C, and a small increase in precipitation. Unlike previous studies in which surface hydrology, and lake evaporation in particular, is driven by an atmospheric model which does not receive any feedback from the lakes, this model does not display a strong trend in evaporation from the lakes. Analysis of the entire water budget of the Great Lakes Basin is still in process, so the overall effect on lake levels is uncertain.

The objective of this study was to determine the effects of postharvest storage at 26 and 3 degree C on the growth and survival of naturally occurring V. parahaemolyticus in shellstock American oysters (Crassostrea virginica). Oysters were collected monthly from May 1998 through April 1999 from Mobile Bay, Alabama, and their V. parahaemolyticus densities were determined after 0, 5, 10, and 24 h of postharvest storage at 26 degree C. After 24 h of storage at 26 degree C, oysters were transferred to a refrigerator at 3 degree C and analyzed 14 to 17 days later. V. parahaemolyticus numbers were determined by a direct plating method involving an alkaline-phosphatase-labeled DNA probe that targets the species-specific thermolabile hemolysin gene (tlh-AP) to identify suspect isolates. From April to December, when water temperatures at harvest were >20 degree C, the geometric mean harvest density of V. parahaemolyticus was 130 CFU/g. When water temperatures were <20 degree C, the geometric mean harvest density was 15 CFU/g. After harvest, V. parahaemolyticus multiplied rapidly in live oysters held at 26 degree C, showing a 50-fold increase (1.7 log CFU/g) at 10 h and a 790-fold increase (2.9 log CFU/g) at 24 h (April through December). Average V. parahaemolyticus numbers showed a sixfold decrease (0.8 log CFU/g) after approximately 14 days of refrigeration. These results indicate that V. parahaemolyticus can grow rapidly in unrefrigerated oysters.

Denitrification was determined by the rate of increase in N sub(2) relative to Ar, measured using membrane-inlet mass spectrometry. Although sediments were a source of recycled (mineralized) inorganic nitrogen (primarily as NH super(+) sub(4)) and phosphorus, they only supplied approximately 1% of total nitrogen required by water column primary production. Overall, sediments were a net sink for total nitrogen due to denitrification. On average denitrification removed 1.7 mmol N m super(-2) d super(-1) and was related to sediment oxygen consumption (SOC), suggesting that nitrogen regenerated from organic matter in the sediment and subsequently nitrified was an important nitrate source for benthic denitrifying bacteria. Coupled nitrification-denitrification was estimated to support 91-100% of total denitrification in LEO-15 sediments. Denitrification in these sediments was an important pathway for carbon mineralization, on average accounting for 13% of total mineralization (2-62%). Denitrification was not related to the organic content of the sediment suggesting that quality of organic matter, rather than simply quantity, was important in controlling denitrification in continental shelf sediments. Denitrification, SOC, and nutrient fluxes showed no strong seasonal patterns. The pattern of N sub(2)O flux was related to bottom water N sub(2)O concentration. Nitrous oxide supersaturation during the summer resulted in flux into sediments, whereas near equilibrium N sub(2)O concentrations during the spring and autumn resulted in flux out of sediments.

Flooding flow is the flow required to cause a stream to slightly overflow its bank and cause damage. Threshold runoff [L], defined as the depth of runoff required to cause flooding, is computed as flooding flow divided by the unit hydrograph peak flow. A key assumption in this work is that the two-year return flood (Q sub(2)) is a useful surrogate for flooding flow. The application described here computes flood magnitude estimates for selected return periods (Q sub(2), Q sub(5), Q sub(10), etc.) using regression equations published by the U.S. Geological Survey for each of 210 hydrologic regions. The application delineates basin boundaries and computes all basin parameters required for the flood frequency calculations. The geographic information system database that supports these calculations contains terrain data [digital elevation models (DEMs) and DEM derivatives], reference data, and 89 additional data layers related to climate, soils, geology, and land use. Initial results indicate that there are some practical limitations associated with using Q sub(2) regression equations to estimate flooding flow.

This observational study statistically links hourly rainfall rates observed by tipping-bucket rain gauges in California's quasi-linear coastal mountains to the hourly averaged upslope component of the flow measured by coastal wind profilers immediately upstream. Vertical profiles of the linear correlation coefficient of upslope flow versus rain rate are calculated on a case-by-case basis, for all cases containing a low-level jet (LLJ), and for the winter season of 1997/98. These correlation coefficient profiles show a direct relationship between the magnitude of the upslope flow impacting the coast and the magnitude of the rain rate in the downstream coastal mountains. Maximum correlation coefficients are as large as 0.94 in some individual cases, 0.75 for a composite of LLJ cases, and 0.70 for the winter season. Using three locations with differing coastal terrain characteristics, it is found that the layer of upslope flow that optimally modulates orographic rainfall is near mountaintop, that is, about 1 km above mean sea level for California's coastal ranges. This height also corresponds to the mean altitude of landfalling LLJs observed by the coastal profilers. The correlation coefficient in this layer is largest when the rain rates are used from the coastal mountain sites rather than from the coastal sites, thus further highlighting the physical connection between upslope flow and orographic rainfall in the coastal mountains. The presence of shallow, terrain-blocked flow modulates the correlation coefficient profiles below mountaintop, such that the low-level flow at the coast is poorly correlated with rain rates observed in the coastal mountains. However, cases without significant blocking retain relatively large correlation coefficient values below mountaintop. Landfalling LLJs produce the largest enhancement of upslope flow at the altitude of the LLJ, despite the existence of terrain-modified flows below mountaintop during some LLJ events. The steepest increase in rain rate for a given increase in upslope flow also occurs at jet level, as does the largest correlation coefficient of upslope flow versus rain rate. Therefore, the upslope-induced orographic rain-rate response associated with landfalling LLJs is largest (2.55 mm h-1) and statistically most robust near the altitude of those LLJs.

Embedded within this combined disturbance, some semblance of the incipient individual mesoscale disturbances may be preserved, especially in instances when the individual forcing mechanisms are fixed in space, as in the case of the Great Lakes. Studies have shown that during prolonged cold air outbreaks, collective lake disturbances can originate from the organization of individual lake-scale disturbances. These collective lake disturbances may, through scale interactions, alter the behavior of the contributing individual lake-scale disturbances and the embedded lake-effect storms. Factor separation decomposition of the Great Lakes system indicates that various interactions among lake-scale processes contribute to the overall development of the regional-scale disturbance, which can modulate embedded lake-effect snowbands. Contributions from these interactions tend to offset the individual lake contributions, especially during the development of the collective lake disturbance, but vary spatially and temporally. As the regional-scale disturbance matures, lake-lake interactions then accentuate the individual lake contributions. Specifically, the modulation of lake-effect snowbands was translational, intensional, and in some instances morphological in nature. Near Lake Michigan, processes attributed to Lake Superior (upstream lake) were direct and synergistic (indirect) resulting in a time delay of maximum snowfall intensity, while processes attributed to the downstream lakes were primarily synergistic resulting in an overall decrease in snowfall intensity. Furthermore, as the collective lake disturbance matured, Lake Superior-induced processes contributed to a significant morphological change in the Lake Michigan lake-effect snowbands.

Although cattle grazing is a well-described source of disturbance in stream habitats, the effects of manure inputs have not been previously isolated from effects of the physical disturbance. We traced the responses of aquatic insects representing 5 different functional-feeding groups to this introduced food source. We simulated manure enrichment from light grazing intensity and hypothesized that insects that feed directly on imported organic matter (shredders, filterers, gatherers) would have higher assimilation rates and densities than predators or periphyton-grazers in response to manure enrichment. We expected insect responses to increase with incremental enrichment over time, and decrease with increasing distance from the manure input. We introduced manure (composed of undigested C sub(4) plant particles) from corn-fed cows into 7 streams that drain forests of C sub(3) plants in Coastal and Sierra Nevada regions in California. Stable C isotope ratios indicated all feeding groups assimilated the isotopically distinct manure. In the Coastal streams, groups assimilating the most manure were gatherers (net increase of 21% towards C sub(4) plant signal) and filterers (20%), whereas shredders (9%) assimilated the least. In the faster-flowing Sierran streams, assimilation by each group was less than or equal to 9%. Temporal increases in manure uptake were detected in the Coastal mayfly gatherer Paraleptophlebia pallipes, suggesting increased manure assimilation over time. Manure uptake by insects was spatially localized within 3 m downstream of the site of manure input. Densities of all 6 genera representing 5 functional-feeding groups were not significantly altered in response to manure enrichment. However, chironomids increased >5-fold in densities after 4 wk of enrichment. The composition of chironomid genera did not shift, and insect taxa richness in the enriched treatments did not change in response to manure enrichment. In our simulation of enrichment effects, which approximated low-density grazing of 6 cows visiting each stream reach weekly for 8 wk, we found that in the absence of physical disturbances from cattle grazing, manure is an important food source for gatherers in particular, and elicited responses from chironomids that are characteristic of organic enrichment.

Part III: Interannual Variability AN - 18423359; 5401212 AB - The Land Dynamics (LaD) model is tested by comparison with observations of interannual variations in discharge from 44 large river basins for which relatively accurate time series of monthly precipitation (a primary model input) have recently been computed. When results are pooled across all basins, the model explains 67% of the interannual variance of annual runoff ratio anomalies (i.e., anomalies of annual discharge volume, normalized by long-term mean precipitation volume). The new estimates of basin precipitation appear to offer an improvement over those from a state-of-the-art analysis of global precipitation (the Climate Prediction Center Merged Analysis of Precipitation, CMAP), judging from comparisons of parallel model runs and of analyses of precipitation-discharge correlations. When the new precipitation estimates are used, the performance of the LaD model is comparable to, but not significantly better than, that of a simple, semiempirical water-balance relation that uses only annual totals of surface net radiation and precipitation. This implies that the LaD simulations of interannual runoff variability do not benefit substantially from information on geographical variability of land parameters or seasonal structure of interannual variability of precipitation. The aforementioned analyses necessitated the development of a method for downscaling of long-term monthly precipitation data to the relatively short timescales necessary for running the model. The method merges the long-term data with a reference dataset of 1-yr duration, having high temporal resolution. The success of the method, for the model and data considered here, was demonstrated in a series of model-model comparisons and in the comparisons of modeled and observed interannual variations of basin discharge.

We present a large data set, collected under variable field conditions, to compare measurements of visual water clarity between the horizontal black disc, a horizontal Secchi disc, and 2 more traditional techniques: a vertical Secchi disc and an electronic nephelometer. Distance readings between the 2 horizontal discs were nearly equivalent (r = 0.98). The horizontal discs provided a measure of visibility that was strongly correlated with that of the vertical Secchi disc (r = 0.96, 0.93). Correlation between measurements made with visual discs and with the electronic nephelometer was high (-0.86 < r < -0.85) but not as high as among measurements made using the 3 types of visual disc. The coefficient of variation, a relative indicator of precision, was similar for the 3 visual methods but higher for the electronic nephelometer. Analyses indicated that there was variation in horizontal disc distance readings among observers. We recommend the use of horizontal visual discs by trained observers as an inexpensive, practical, and precise tool for measuring visual water clarity.

The method of Crow & Morton (1955) for scaling demographic data collected at a juvenile stage to expected values at adulthood is extended to consider sequential episodes of random and family correlated survival. Results show the following: (i) The order in which the episodes of random and family-correlated survival occur does not affect N sub(e) or N sub(e)/N; (ii) If a population experiences an episode of family-correlated survival, N sub(e)/N scaled to its expected value in a population of constant size (k = 2) is simply the survival rate during the family-correlated stage. If multiple such stages occur, scaled N sub(e)/N is the product of the survivals during all family-correlated life stages; (iii) Under the assumption of random post-enumeration survival, adjusting the variance effective size to its expected value at k = 2 is equivalent to computing the inbreeding effective size at the earlier life stage. Application to experimental data for hatchery populations of Pacific salmon (Oncorhynchus spp.) indicates that nonrandom survival during the marine phase led to estimated reductions in effective size of 0-62% (mean 19%) in 12 different cohorts. This approach can provide insights into N sub(e)/N in highly fecund species, including some marine species in which N sub(e) has been estimated to be several orders of magnitude less than N.

The ladders were constructed by pooling polymerase chain reaction (PCR) products to create a template for amplification. Four ladders were field-tested in six different laboratories using different genotyping platforms. Despite substantial differences in absolute size estimates of DNA fragments, each laboratory correctly scored unknown sample genotypes according to the ladder designations. The results indicate that our simple preparation method provides reliable allele ladders in a time-efficient manner for verifying microsatellite genotypes across platforms.

Supportive breeding is the boosting of a wild population's size by breeding part of the population in captivity and releasing the captive progeny back into the wild. The model assumes that a single trait is under selection with different optimum trait values in the captive and wild environments. The model shows that when the captive population is closed to gene flow from the wild population, even low levels of gene flow from the captive population to the wild population will shift the wild population's mean phenotype so that it approaches the optimal phenotype in captivity. If the captive population receives gene flow from the wild, the shift in the wild population's mean phenotype becomes less pronounced but can still be substantial. The approach to the new mean phenotype can occur in less than 50 generations. The fitness consequences of the phenotypic shift depend on the details of the model, but a>30% decline in fitness can occur over a broad range of parameter values. The rate of gene flow between the two environments, and hence the outcome of the model, is sensitive to the wild environment's carrying capacity and the population growth rate it can support. The results have two important implications for conservation efforts. First, they show that selection in captivity may significantly reduce a wild population's fitness during supportive breeding and that even continually introducing wild individuals into the captive population will not eliminate this effect entirely. Second, the sensitivity of the model's outcome to the wild environment's quality suggests that conserving or restoring a population's habitat is important for preventing fitness loss during supportive breeding.

Rotated empirical orthogonal function (REOF) analysis is applied to isolate dominant patterns of rainfall. Links of these patterns to sea surface temperature anomalies (SSTAs) are examined. The leading mode is related to El Nino-Southern Oscillation (ENSO), which explains 12% of the total variance. During warm ENSO events, the positive phase of this mode shows dry conditions over northern South America and wet conditions over the subtropical plains between 25 ' and 35 'S. The situation reverses during cold events. The second REOF 2, which explains about 10.8% of the total variance, consists of positive loadings over northeast Brazil centered at 50 'W near the equator and negative loadings over Colombia and the subtropical plains. For December-January-February (DJF), REOF 2 is influenced by tropical South Atlantic SSTAs through displacements of the intertropical convergence zone. Northeast Brazil receives most rainfall in March-April-May (MAM) and it is modulated by both the Atlantic SSTAs and ENSO. In the interannual frequency band, the North Atlantic Oscillation (NAO) has very limited influence on rainfall. On the decadal timescales, the NAO leads REOF 2 by three years. Latitudinal variations of tropical convection are through the joint contribution of REOF 2 and REOF 4. REOF 4 is similar to REOF 2, but centers are displaced about 10 ' south. When these two EOFs are both positive, central South America is wet. The amplitudes of REOF 2 and REOF 4 are small during the mid-1950s to the mid-1960s and they are out of phase from 1968 to 1970, periods with persistent dry conditions over the upper La Plata River basin.

The 2BW method has the advantage of being much less sensitive than the standard single-beamwidth (1BW) method to the necessary instrumental corrections of the observed velocity variance sigma sub(obs) super(2). We test and compare the 2BW and 1BW methods using sigma sub(obs) super(2) between 5.0 and 7.5 km MSL measured by the MU VHF radar near Shigaraki, Japan, with beams directed toward 10 degree zenith angle. We find that during periods of light winds the sigma sub(turb) super(2) profiles from the two methods agree well. But with wind speeds >30 m/s the 1BW values of sigma sub(turb) super(2) are about 25% larger than the 2BW values. With the 2BW method, typical values of sigma sub(turb) super(2) between 6.0 and 7.5 km MSL increased from 0.07 m super(2)/s super(2) with winds of 2 m/s to 0.2 m super(2)/s super(2) with winds between 30 and 60 m/s.

Part I: The Land Dynamics (LaD) Model AN - 1665487516; 5401210 AB - A simple model of large-scale land (continental) water and energy balances is presented. The model is an extension of an earlier scheme with a record of successful application in climate modeling. The most important changes from the original model include 1) introduction of non-water-stressed stomatal control of transpiration, in order to correct a tendency toward excessive evaporation; 2) conversion from globally constant parameters (with the exception of vegetation-dependent snow-free surface albedo) to more complete vegetation and soil dependence of all parameters, in order to provide more realistic representation of geographic variations in water and energy balances and to enable model-based investigations of land-cover change; 3) introduction of soil sensible heat storage and transport, in order to move toward realistic diurnal-cycle modeling; 4) a groundwater (saturated-zone) storage reservoir, in order to provide more realistic temporal variability of runoff; and 5) a rudimentary runoff-routing scheme for delivery of runoff to the ocean, in order to provide realistic freshwater forcing of the ocean general circulation model component of a global climate model. The new model is tested with forcing from the International Satellite Land Surface Climatology Project Initiative I global dataset and a recently produced observation-based water-balance dataset for major river basins of the world. Model performance is evaluated by comparing computed and observed runoff ratios from many major river basins of the world. Special attention is given to distinguishing between two components of the apparent runoff ratio error: the part due to intrinsic model error and the part due to errors in the assumed precipitation forcing. The pattern of discrepancies between modeled and observed runoff ratios is consistent with results from a companion study of precipitation estimation errors. The new model is tuned by adjustment of a globally constant scale factor for non-water-stressed stomatal resistance. After tuning, significant overestimation of runoff is found in environments where an overall arid climate includes a brief but intense wet season. It is shown that this error may be explained by the neglect of upward soil water diffusion from below the root zone during the dry season. With the exception of such basins, and in the absence of precipitation errors, it is estimated that annual runoff ratios simulated by the model would have a root-mean-square error of about 0.05. The new model matches observations better than its predecessor, which has a negative runoff bias and greater scatter.

Part II: Land-Characteristic Contributions to Spatial Variability AN - 1665487495; 5401211 AB - Land water and energy balances vary around the globe because of variations in amount and temporal distribution of water and energy supplies and because of variations in land characteristics. The former control (water and energy supplies) explains much more variance in water and energy balances than the latter (land characteristics). A largely untested hypothesis underlying most global models of land water and energy balance is the assumption that parameter values based on estimated geographic distributions of soil and vegetation characteristics improve the performance of the models relative to the use of globally constant land parameters. This hypothesis is tested here through an evaluation of the improvement in performance of one land model associated with the introduction of geographic information on land characteristics. The capability of the model to reproduce annual runoff ratios of large river basins, with and without information on the global distribution of albedo, rooting depth, and stomatal resistance, is assessed. To allow a fair comparison, the model is calibrated in both cases by adjusting globally constant scale factors for snow-free albedo, non-water-stressed bulk stomatal resistance, and critical root density (which is used to determine effective root-zone depth). The test is made in stand-alone mode, that is, using prescribed radiative and atmospheric forcing. Model performance is evaluated by comparing modeled runoff ratios with observed runoff ratios for a set of basins where precipitation biases have been shown to be minimal. The withholding of information on global variations in these parameters leads to a significant degradation of the capability of the model to simulate the annual runoff ratio. An additional set of optimization experiments, in which the parameters are examined individually, reveals that the stomatal resistance is, by far, the parameter among these three whose spatial variations add the most predictive power to the model in stand-alone mode. Further single-parameter experiments with surface roughness length, available water capacity, thermal conductivity, and thermal diffusivity show very little sensitivity to estimated global variations in these parameters. Finally, it is found that even the constant-parameter model performance exceeds that of the Budyko and generalized Turc-Pike water-balance equations, suggesting that the model benefits also from information on the geographic variability of the temporal structure of forcing.

Called the precipitation reconstruction (PREC), the global analyses are defined by interpolation of gauge observations over land (PREC/L) and by EOF reconstruction of historical observations over ocean (PREC/O). This paper documents the creation of the land component of the analyses (PREC/L) on a 2.5 ' latitude/longitude grid for 1948-2000. These analyses are derived from gauge observations from over 17 000 stations collected in the Global Historical Climatology Network (GHCN), version 2, and the Climate Anomaly Monitoring System (CAMS) datasets. To determine the most suitable objective analysis procedure for gridding, the analyses generated by four published objective analysis techniques [those of Cressman, Barnes, and Shepard, and the optimal interpolation (OI) method of Gandin] were compared. The evaluation demonstrated two crucial points: 1) better results are obtained when interpolating anomalies rather than the precipitation totals, and 2) the OI analysis procedure provided the most accurate and stable analyses among the four algorithms that were tested. Based on these results, the OI technique was used to create monthly gridded analyses of precipitation over the global land areas for the 53-yr period from 1948 to 2000. In addition, some diagnostic investigations of the seasonal and interannual variability of large-scale precipitation over the global land areas are presented. The mean distribution and annual cycle of precipitation observed in the PREC/L showed good agreement with those in several published gauge-based datasets, and the anomaly patterns associated with ENSO resemble those found in previous studies. The gauge-based dataset (PREC/L) will be updated on a quasi-real-time basis and is available online ().

As many as 24 life cycle stages were originally described for this species. During a recent phylogenetic study in which we used clonal cultures of P. piscicida , we were unable to confirm many reported life cycle stages. To resolve this discrepancy, we undertook a rigorous examination of the life cycle of P. piscicida using nuclear staining techniques combined with traditional light microscopy, high-resolution video microscopy, EM, and in situ hybridization with a suite of fluorescently labeled peptide nucleic acid (PNA) probes. The results showed that P. piscicida had a typical haplontic dinoflagellate life cycle. Asexual division occurred within a division cyst and not by binary fission of motile cells. Sexual reproduction of this homothallic species occurred via the fusion of isogamous gametes. Examination of tanks where P. piscicida was actively feeding on fish showed that amoebae were present; however, they were contaminants introduced with the fish. Whole cell probing using in situ hybridization techniques confirmed that these amoebae were hybridization negative for a P. piscicida -specific PNA probe. Direct observations of clonal P. piscicida cultures revealed no unusual life cycle stages. Furthermore, the results of this study provided no evidence for transformations to amoebae. We therefore conclude that P. piscicida has a life cycle typical of free-living marine dinoflagellates and lacks any amoeboid or other specious stages.

Measured carbon monoxide (CO) and nitrogen oxide (NO sub(x)) concentrations from two urban areas show that the CO/NO sub(x) vehicular emission ratio has decreased at an average rate of 7-9% per year from 1987 to 1999. This amounts to a factor of nearly 3 over the 12 years. The current U.S. Environmental Protection Agency tabulations of estimated pollutant emission trends indicate a rate of decrease smaller by a factor of 2-3. The trend in maximum ambient CO levels in U.S. cities suggests a 5.2 plus or minus 0.8% per year average annual decrease in CO vehicular emissions, which implies a 2-3% annual increase in NO sub(x) emissions from vehicles. Thus over the decade of the 1990s, annual U.S. CO emissions from vehicles have decreased from 65 to 38 Tg, representing approximate decreases of 6 and 3% in the annual global fuel-use CO emissions and in total global anthropogenic CO emissions, respectively. It is expected that the volatile organic compound (VOC)/NO sub(x) vehicular exhaust emission ratio has decreased similarly, implying that the character of atmospheric photochemistry in U.S. urban areas has changed significantly over the decade.

The predictors are the global sea surface temperature (SST), 200-hPa streamfunction with zonal means removed (PSI), and forecasts or simulations from the climate models. The canonical correlation analysis (CCA) is performed for each variable separately. These predicted precipitation fields form an ensemble. The ensemble mean is the equal weighted average of its members. For both the multi-model simulations and seasonal hindcasts, the CCA correction improves forecast skill. The ensemble, which consists of the CCA precipitation forecasts based on SST, PSI and the CCA corrected model simulations gives the highest skill. Each member has forecast skill over the different parts of the Sahel. Therefore, the ensemble mean has higher skill than its individual members.

Complex instrumentation also allows these animals to provide oceanographic data, although such collection is challenged by determining the site where data are collected, and the need to recapture the animal to collect the tag-contained data. The northern elephant seal is considered an ideal oceanographic indicator, since it migrates throughout the northeastern Pacific over nine months. Additional species under consideration include tunas, billfish, sharks, seabirds, and whales.

The success of a restoration is measured through numerous biological and ecological indicators, including bacteria. This examination of bacterial communities at a restoration site and adjacent control sites included the assessment of eight sediment cores with and without an algal mat. This mat was a clear indicator of the type of bacterial community. After the estuary site was restored the community of bacteria associated with algal mats was not sufficiently restored, possibly as a result of the depth-driven chemox gradient.

(FINAL SUPPLEMENT TO THE DRAFT ENVIRONMENTAL IMPACT STATEMENT) AN - 36416102; 9340 AB - PURPOSE: A regulatory adjustment of the fishery management plan (FMP) for Atlantic tunas, swordfish, and sharks is proposed. The target species are highly migratory species (HMS) inhabiting the Atlantic Ocean, the Gulf of Mexico, and the Caribbean Sea. The intent of the proposed actions is to reduce bycatch and bycatch mortality of sea turtles by U.S. commercial fishermen who hold permits for the catch of HMS and use pelagic longline gear in the Atlantic Ocean. Pelagic longline gear is the dominant gear used by U.S. fishermen in the Atlantic Ocean to target HMS. Furthermore, it is commonly used by vessels flying under various national flags fishing the waters of the Western Atlantic. Longline gear can be modified to target yellowfin tuna, bigeye tona, sharks, or swordfish. However, the gear also catches other species, including sea turtles, that are not the intended target species. The proposed action would close the Northeast Distant Statistical Reporting Area to pelagic longline fishing. In addition to the area closure, the rule would require the HMS pelagic longline fleet to modify the manner in which fishing is conducted. Gangions would be required to be 10 percent longer than floatlines in sets of 100 meters or less. Additionally, gangions would be prohibited from being set within two gangion lengths of the floatlines. Corrodible hooks and/or crimps (proposed to be non-stainless steel) would be required fleetwide. In addition to these gear modifications, vessel operators in the fleet would be required to report lethal sea turtle takes within 48 hours of returning to port and to post sea turtle handling and release guidelines in the wheelhouse. Fishermen in the bottom longline fishery would be required to post sea turtle handling and release guidelines in the wheelhouse. Fishermen in the shark gillnet fishery would be required to look for sea turtles and marine mammals every 30 minutes to two hours during net checks. Any entangled animals would have to be removed from the net. The regulations concerning the shark fishery would be amended to clarify that both the observer and vessel operator would be responsible for sighting whales and contacting the National Marine Fisheries Service. POSITIVE IMPACTS: By reducing bycatch and incidental catch, the regulatory amendments would improve the sustainability of sea turtles and other HMS species. NEGATIVE IMPACTS: Certain fishery management provisions, particularly gear restrictions and the area closure, could result in economic losses to fishing interests.

Preparation date: May 31, 2002 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - FISHERY MANAGEMENT PLAN FOR DEEP-SEA RED CRAB (CHACEON QUINQUEDENS), NEW ENGLAND. AN - 36410494; 9334 AB - PURPOSE: The implementation of a fishery management plan (FMP) for the deep-sea red crab fishery off the coast of New England and the Mid-Atlantic is proposed. The fishery management unit is bounded on the south by Cape Hatteras, North Carolina, on the north and east by the coastline of the continental United States and the eastern boundary of the Exclusive Economic Zone. Since the early 1970s, there has been a small directed red-crab fishery in this region. Faced with increasing landings in recent years and increased interest in the fishery from potential new entrants around the country, fishing interests approached the New England Fishery Management Council in late 1999 with a request that the Council manage red crab. In January 2001, faced with an increasing number of vessels targeting the red crab resource, the Council requested that emergency action be taken to prevent overfishing in the fishery while the Council continued to develop an FMP. Emergency regulations were established on May 8, 2001; these regulations will remain in effect until May 14, 2002. All currently available information indicates that there is a limited maximum sustainable yield of red crab of 6.24 million pounds and that four to six vessels fishing at existing levels of capacity represent the likely maximum harvesting effort that can be sustained by the resource. The addition of new vessels, particularly catcher-processor vessels with increased capacity, would threaten not only the resource but also the viability of the established fishery. Key issues identified during scoping for the FMP include those related to the status of the red crab stock, the availability of data on the resource and the fishery, incidental catch and discards of red crabs in other fisheries, the appropriate levels of fishing power, maintenance of consistent supply of red crabs, compliance with marine mammal protection requirements, area of management jurisdiction, and handling mortality. Ten alternatives, including a No Action Alternative (Alternative 10), are considered in this final EIS. The preferred alternative (Alternative 5) would use a vessel days-at-sea (DAS) allocation based on a target total allowable catch (TAC), in conjunction with a controlled access program, to control fishing effort on the resource. Trip limits would be used to ensure that each trip taken by a red crab vessel was roughly equivalent. The objective of the alternative would be to determine the DAS appropriate to harvest, but not exceed, the target TAC. DAS could be adjusted on an annual basis in response to changing stock conditions and to estimates of the amount of crab likely to be harvested. Some form of trap limit would be established to control the potential fishing power of individual vessels. An incidental catch limit would be established for all vessels not authorized to participate in the directed fishery. In addition the landing of female crabs and the mutilation (claw-snapping) and/or full processing of crabs at sea would be prohibited. POSITIVE IMPACTS: The preferred FMP would prevent overfishing of the red crab resource and overcapitalization of the associated fishery. The plan would allow for the market to control production. Vessels would be able to maximize their outputs from a given level of inputs, assuming that the biomass increased over time. NEGATIVE IMPACTS: Because the calculation of DAS is indirect, the realized catch after one year using all DAS could over- or under-shoot the target TAC.

We examine the hypothesis that the presence of these large carnivores has affected fisheries resources, either through direct predation on larval stages, or through competition for zooplankton prey. In this paper, we explore the impact of this jellyfish increase on zooplankton and fish communities based on field data on the composition of the jellyfish community, and the abundance, size, stable isotopic signatures, and feeding habits of the principal scyphomedusae in the region. These data, together with those on zooplankton biomass, are used to estimate the ecosystem impacts of this increase. The center of jellyfish biomass has shifted from the SE Middle Shelf Domain in the early 1980s to the NW in the late 1990s. In recent years, the species composition of large medusae caught in trawls was dominated (>80% by number and >95% by weight) by the scyphozoan Chrysaora melanaster. Dense aggregations of this species occupied the water column in daytime between 10 and 40 m. Their food habits consisted mainly of pelagic crustaceans (euphausiids, copepods, amphipods), although other jellyfish and juvenile pollock were also consumed. Based on stable isotope ratios, the trophic level of this scyphozoan is equivalent to, or higher than, that of Age 0 pollock. Preliminary estimates showed that medusae have a moderate grazing impact on zooplankton in the area around the Pribilof Islands; C. melanaster was estimated on average to consume seasonally about one-third of the standing stock and 4.7% of the annual production of zooplankton in this region. Daily consumption of Age 0 pollock was estimated to be 2.8% of the standing stock around the Pribilof Islands during 1999. A hypothesis for the increase in jellyfishes observed in the eastern Bering Sea, based on release from competition from planktivorous forage fishes, is proposed.

AN - 1665486000; 5405017 AB - Bay anchovy are known to be an important component of food webs in estuarine and coastal waters along the US East Coast. Despite their role as a primary forage species for several top-level predators in these systems, very little is known about their behavioral interactions with predators and the vulnerability of post-larval life stages to predation. In this study, we examined the vulnerability of juvenile bay anchovy to age-0 bluefish predation using a size-structured laboratory design. For a range of bay anchovy and bluefish body sizes, we determined predator capture success, handling time costs, feeding rates, and prey profitabilities as functions of relative prey size. We evaluated bluefish size selection when offered different sizes of bay anchovy simultaneously and identified behavioral characteristics of prey that may contribute to disparate rates of attack. Bluefish capture success was high on small relative prey sizes (50% of predator size), demonstrating that even large bay anchovy are highly susceptible to capture. Handling time and capture success relationships were combined with prey body mass to generate dome-shaped profitability curves that peaked at relative prey sizes of 0.50, which is much higher than typically observed for piscivore-prey interactions. Bluefish exhibited strong selection patterns and significantly higher attack rates on large bay anchovy. Disparate attack distributions on large and small bay anchovy appeared to be caused partly by differences in prey behavior among size groups. Our results suggest that bay anchovy may not achieve a refuge from predation with increased body size and support the importance of predation in shaping bay anchovy life history.

AN - 36437981; 9298 AB - PURPOSE: An amendment to the reef fish fishery management plan (FMP) for the Gulf of Mexico is proposed to set a 10-year rebuilding plan for red grouper and address associated impacts on gag and other groupers. In October 2000, the National Marine Fisheries Service issued a determination that the Gulf of Mexico red grouper stock has been overfished and is undergoing overfishing. Red grouper are the primary species of a shallow-water grouper aggregate, of which the second most common species is gag. Gag was recently found to be neither overfished nor undergoing overfishing, but was being fished at a rate too high to achieve optimum yield. Deep-water grouper and tilefish are considered probably alternative target stocks by commercial fishing interests displaced by the actions proposed in this draft supplemental EIS. Numerous alternatives, including a No Action Alternative and a preferred alternative, are considered in this draft EIS to address the various issues at hand. The alternatives address sustainable yield, stock size threshold, fishing mortality rate, optimum yield, the rebuilding of overfished stock, rebuilding scenarios, recreational fishing scenarios, shallow-water grouper quotas for red grouper, alternatives to the reduction of fishing mortality, seasonal closures for recreational fishing, longline and buoy gear restrictions, seasonal quotas for red grouper, and deep-water grouper and tilefish quotas. POSITIVE IMPACTS: The proposed amendment would assist in ending overfishing of the red grouper stock and rebuild the fishery. The plan could achieve a 45-percent reduction in total red grouper harvest during the first three years of the plan, with subsequent harvest levels to be determined at an appropriate point in time. NEGATIVE IMPACTS: Quotas and other restrictions would affect recreational fishing and could place economic hardships upon some commercial fishing interests.

Preparation date: May 9, 2002 N1 - Last updated - 2011-12-16 ER - TY - JOUR T1 - Structure and calcium-binding studies of a recoverin mutant (E85Q) in an allosteric intermediate state. AN - 71639211; 11980481 AB - Recoverin, a member of the EF-hand superfamily, serves as a calcium sensor in retinal rod cells. A myristoyl or related fatty acyl group covalently attached to the N-terminus of recoverin facilitates the binding of recoverin to retinal disk membranes by a mechanism known as the Ca2+-myristoyl switch. Previous structural studies revealed that the myristoyl group of recoverin is sequestered inside the protein core in the absence of calcium. The cooperative binding of two calcium ions to the second and third EF-hands (EF-2 and EF-3) of recoverin leads to the extrusion of the fatty acid. Here we present nuclear magnetic resonance (NMR), fluorescence, and calcium-binding studies of a myristoylated recoverin mutant (myr-E85Q) designed to abolish high-affinity calcium binding to EF-2 and thereby trap the myristoylated protein with calcium bound solely to EF-3. Equilibrium calcium-binding studies confirm that only one Ca2+ binds to myr-E85Q under the conditions of this study with a dissociation constant of 100 microM. Fluorescence and NMR spectra of the Ca2+-free myr-E85Q are identical to those of Ca2+-free wild type, indicating that the E85Q mutation does not alter the stability and structure of the Ca2+-free protein. In contrast, the fluorescence and NMR spectra of half-saturated myr-E85Q (one bound Ca2+) look different from those of Ca2+-saturated wild type (two bound Ca2+), suggesting that half-saturated myr-E85Q may represent a structural intermediate. We report here the three-dimensional structure of Ca2+-bound myr-E85Q as determined by NMR spectroscopy. The N-terminal myristoyl group of Ca2+-bound myr-E85Q is sequestered within a hydrophobic cavity lined by many aromatic residues (F23, W31, Y53, F56, F83, and Y86) resembling that of Ca2+-free recoverin. The structure of Ca2+-bound myr-E85Q in the N-terminal region (residues 2-90) is similar to that of Ca2+-free recoverin, whereas the C-terminal region (residues 100-202) is more similar to that of Ca2+-bound wild type. Hence, the structure of Ca2+-bound myr-E85Q represents a hybrid between the structures of recoverin with zero and two Ca2+ bound. The binding of Ca2+ to EF-3 leads to local structural changes within the EF-hand that alter the domain interface and cause a 45 degrees swiveling of the N- and C-terminal domains, resulting in a partial unclamping of the myristoyl group. We propose that Ca2+-bound myr-E85Q may represent a stable intermediate state in the kinetic mechanism of the calcium-myristoyl switch.

AN - 36425048; 9293 AB - PURPOSE: The implementation of an ecosystem-based fishery management plan (FMP) for the coal reef ecosystems of the Western Pacific Region is proposed. Approximately 70 percent of the world's coral reefs and 94 percent of the coral reefs under U.S. jurisdiction are located in the Pacific Ocean. Coral reefs cover an estimated 15,852 square kilometers of shallow ocean bottom around U.S. Pacific island areas served by the Western Pacific Regional Fishery Management Council. The island areas include those associated with Hawaii, American Samoa and Guam, the Commonwealth of the Northern Mariana Islands, and the unincorporated remote areas of Johnston Atoll, Kingman Reef, Palmyra. Midway Atolls, and Jarvis, Howland, Baker, Midway, and Wake islands. Some 90 percent of the coral reefs in the regions exclusive economic zone (EEZ) are found in remove areas away from fishing communities. Coral reefs build atolls, protect island shores from coastal erosion and wave damage, support fisheries of cultural and economic value, provide a natural resource for traditional healing and biomedical research, and serve as museums of the world's tropical marine biodiversity. Local regulations control most of the impacts of resource exploitation on nearshore coral reefs in settled areas. The proposed FMP would implement a precautionary approach to protection of coral reefs in the EEZ. Although these areas have been minimally exploited to date, there is potential for fisheries to expand in these areas. Management measures would include those associated with marine protected areas, including the Pacific remote island areas, the Northwestern Hawaiian Islands, Guam's Southern Banks, and Rose Atoll in American Samoa; measures for permits and monitoring, restrictions on fishing gear and fishing methods; an adaptive management framework; and non-regulatory measures. Four alternatives, including a No Action Alternative (Alternative 1), are considered in this final EIS. The preferred alternative (Alternative 3) would institute a regime resulting in substantial additional protection of the coral reef resource. POSITIVE IMPACTS: The holistic FMP would provide for a better understanding of impacts resulting from natural environmental changes, other FMP managed fisheries, and non-fishing anthropogenic activities such as dredging. Potential expansion of fishery resources would include nearshore fisheries for coral reef species, new fisheries for the live fish markets in South East Asia, expanded fisheries for coral and "live rock" for the U.S. aquarium trade, and pharmaceutical resources. NEGATIVE IMPACTS: The preferred FMP would not prevent overfishing of potentially harvestable resources of nearshore target stocks and non-target resources managed by island governments, including live rock and stony coral. Marine debris impacts would not be mitigated. The risk of vessel ground would continue, though this potential could be reduced somewhat. The introduction of invasive alien species on derelict fishing gear drifting in to the region from the North Pacific would not be prevented. The FMP would also fail to prevent the loss of biodiversity, undesirable changes in species dominance, the decline of customary and traditional uses, and degradation of environmental quality in nearshore coral reef ecosystems management by island governments.

AN - 36388728; 9293-020177_0003 AB - PURPOSE: The implementation of an ecosystem-based fishery management plan (FMP) for the coal reef ecosystems of the Western Pacific Region is proposed. Approximately 70 percent of the world's coral reefs and 94 percent of the coral reefs under U.S. jurisdiction are located in the Pacific Ocean. Coral reefs cover an estimated 15,852 square kilometers of shallow ocean bottom around U.S. Pacific island areas served by the Western Pacific Regional Fishery Management Council. The island areas include those associated with Hawaii, American Samoa and Guam, the Commonwealth of the Northern Mariana Islands, and the unincorporated remote areas of Johnston Atoll, Kingman Reef, Palmyra. Midway Atolls, and Jarvis, Howland, Baker, Midway, and Wake islands. Some 90 percent of the coral reefs in the regions exclusive economic zone (EEZ) are found in remove areas away from fishing communities. Coral reefs build atolls, protect island shores from coastal erosion and wave damage, support fisheries of cultural and economic value, provide a natural resource for traditional healing and biomedical research, and serve as museums of the world's tropical marine biodiversity. Local regulations control most of the impacts of resource exploitation on nearshore coral reefs in settled areas. The proposed FMP would implement a precautionary approach to protection of coral reefs in the EEZ. Although these areas have been minimally exploited to date, there is potential for fisheries to expand in these areas. Management measures would include those associated with marine protected areas, including the Pacific remote island areas, the Northwestern Hawaiian Islands, Guam's Southern Banks, and Rose Atoll in American Samoa; measures for permits and monitoring, restrictions on fishing gear and fishing methods; an adaptive management framework; and non-regulatory measures. Four alternatives, including a No Action Alternative (Alternative 1), are considered in this final EIS. The preferred alternative (Alternative 3) would institute a regime resulting in substantial additional protection of the coral reef resource. POSITIVE IMPACTS: The holistic FMP would provide for a better understanding of impacts resulting from natural environmental changes, other FMP managed fisheries, and non-fishing anthropogenic activities such as dredging. Potential expansion of fishery resources would include nearshore fisheries for coral reef species, new fisheries for the live fish markets in South East Asia, expanded fisheries for coral and "live rock" for the U.S. aquarium trade, and pharmaceutical resources. NEGATIVE IMPACTS: The preferred FMP would not prevent overfishing of potentially harvestable resources of nearshore target stocks and non-target resources managed by island governments, including live rock and stony coral. Marine debris impacts would not be mitigated. The risk of vessel ground would continue, though this potential could be reduced somewhat. The introduction of invasive alien species on derelict fishing gear drifting in to the region from the North Pacific would not be prevented. The FMP would also fail to prevent the loss of biodiversity, undesirable changes in species dominance, the decline of customary and traditional uses, and degradation of environmental quality in nearshore coral reef ecosystems management by island governments.

Factors were release date and environmental variables measuring river discharge (flow), water temperature, and the percentage of total flow passed over spillways at dams. Data were collected from migrant salmonids tagged with passive integrated transponder (PIT) tags from 1995 through 1999. The greatest distance over which survival could be estimated during all 5 years was from the Lower Granite Dam tailrace to the McNary Dam tailrace (225 river km encompassing four dams and reservoirs). Release groups consisted of PIT-tagged fish leaving Lower Granite Dam daily. Data from more than 451,000 PIT-tagged yearling chinook salmon and 204,000 PIT-tagged steelhead were analyzed. For each daily group, indices of exposure to environmental factors were calculated as the average value for the factor during an index period of the group's downstream passage. For both species, flow volume and travel time were strongly correlated within single years, and the regression equation was consistent from year to year. Survival estimates changed very little within any given migration season, despite sometimes great fluctuations in environmental factors. Correlations between river discharge and survival between Lower Granite Dam and McNary Dam and between travel time and survival were neither strong (within or between years) nor consistent from year to year. Thus, survival benefits to the stocks from increased flow in this stretch of the river were at best minimal; any measurable benefits occurred downstream from the Snake River.

AN - 85374473; pmid-12051418 AB - Full-field acoustic methods for current velocity inversion require accurate and efficient mathematical models of sound propagation in a range-dependent waveguide with flow. In this paper, an exact coupled-mode representation of the acoustic field is derived. To account for the physics of the problem, normal modes in a corresponding range-independent waveguide are chosen as the local basis. In the absence of currents, mode shape functions form a complete orthogonal basis. This property is heavily used in coupled-mode theories of sound propagation in motionless fluid. Unlike in the motionless case, however, vertical dependencies of acoustic pressure in individual normal modes are not orthogonal in the presence of currents. To overcome this difficulty, linearized equations of hydrodynamics are rewritten in terms of a state vector. Its five components are expressed in terms of acoustic pressure and particle displacement due to the wave. Orthogonality of the state vectors corresponding to individual normal modes is established. Coupled differential equations are derived for range-dependent mode amplitudes, leading to a remarkably simple result. The mode-coupling equations have the same form as those known for the motionless case, but of course the values of the mode-coupling coefficients differ as long as the range dependence of the flow velocity contributes to mode coupling in addition to the range dependence of sound speed and fluid density. The mode-coupling formulation is verified against known coupled-mode equations for certain limiting cases and an exact analytic solution of a benchmark problem.

AN - 71666085; 12003014 AB - The presence in the atmosphere of radioactive debris from nuclear tests provided a unique opportunity to study atmospheric motions and transfers of trace substances. Measurements of the concentrations in air of radionuclides were used to verify trajectories derived solely from weather data. The profiles of radioactive concentration along the aircraft tracks were non-Gaussian. High-flying aircraft and balloons collected air and particulate samples to approximately 30,000 m from Alaska to South America. The measurements from these samples were used in verifying stratospheric motions on a hemispheric and global scale.

We present evidence that recent trends in the SH tropospheric circulation can be interpreted as a bias toward the high-index polarity of this pattern, with stronger westerly flow encircling the polar cap. It is argued that the largest and most significant tropospheric trends can be traced to recent trends in the lower stratospheric polar vortex, which are due largely to photochemical ozone losses. During the summer-fall season, the trend toward stronger circumpolar flow has contributed substantially to the observed warming over the Antarctic Peninsula and Patagonia and to the cooling over eastern Antarctica and the Antarctic plateau.

Alaska is divided into interior and coastal zones with consistent but different climatic variability separated by a transition region; it has maximum internannual variability but low long-term mean variability. Pacific decadal oscillation (PDO)-and El Nino southern oscillation (ENSO)-type events influence Alaska surface temperatures weakly (1-2 degrees C) statewide. PDO has a stronger influence than ENSO on precipitation but its influence is largely localized to coastal central Alaska. The strongest influence of Arctic oscillation (AO) occurs in northern and interior Alaskan precipitation. Four major ecosystems are defined. A major eco-transition zone occurs between the interior boreal forest and the coastal rainforest. Variability in insolation, surface temperature, precipitation, continentality, and seasonal changes in storm track direction explain the mapped ecosystems. Lack of westward expansion of the interior boreal forest into the western shrub tundra is influenced by the coastal marine boundary layer (enhanced cloud cover, reduced insolation, cooler surface and soil temperatures). In this context, the marine boundary layer acts in an analogous fashion to the orographic features which form the natural boundaries of other Alaskan ecosystems. Variability in precipitation may play a secondary role.

Deterministic numerical modeling of future shoreline position for the Lake Michigan Potential Damages Study was completed with the Flood and Erosion Prediction System (FEPS). The FEPS integrates GIs technology, numerical models, and custom visualization tools in a modular system. A critical input to the numerical models is accurate and detailed historic shoreline change rates for sandy and high bluff shorelines. After an extensive review of the published Average Annual Recession Rates for Lake Michigan, significant limitations in the data sources, calculation methods and the resulting Shoreline Change Rates (SCR) were documented. The coastal database for the study included a rich dataset of dune crest / bluff top and toe mapping for five temporal periods in the 1900s. A series of automated ArcGIS tools were developed for the FEPS to pre-process the geo-spatial data and calculate detailed shoreline change rates to support the numerical modeling. The presentation will include a review of previous methods to calculate SCRs for the Great Lakes Basin, the new techniques developed for the study, and a comparison of the published data and the rates calculated with the FEPS. Ongoing studies with repetitive LIDAR surveys for sandy and high bluff environments will also be presented, along with recommendations for future reporting of 3D SCRs.

The task of meeting these demands is becoming increasingly complex due to the rapidly increasing population in coastal areas, economic and demographic shifts, changing land and water uses, and the overlay of evolving local, state and federal authorities, programs and policies. Across a broad array of federal programs and policies concerning shoreline management, there are no unifying objectives. Federal programs and policies have been independently developed without a view toward a coherent and consistent framework for managing the shore. This lack of coordination extends across federal, state and local responsibilities. The absence of overarching objectives has created a void in policy, which is being filled by political directives and budgetary expediency. The uncertainty over the federal policy in responding to shoreline change has lent itself to a divisive policy debate. The lack of a coordinated federal policy for responding to shoreline change is resulting in intergovernmental conflicts, and undermining public confidence in the capability of government to effectively address the problems associated with shoreline management. As with current efforts to undertake holistic approaches to restoring and protecting coastal water quality and managing ocean uses and resources, a more comprehensive approach is needed in responding to shoreline change. The policies guiding responses to shoreline change need to require the best utilization of data and information on littoral processes, provide for tailored responses to meet regional objectives, and accommodate local conditions.

AN - 19731113; 7321562 AB - Low altitude aerial photography has traditionally provided a rich data source for shoreline change analysis, particularly with respect to capturing historic shoreline positions. While some historic flights have ground control and have been processed for three-dimensional (3D) topography, most do not have significant ground control to do so. Therefore, the wet/dry line, the visible demarcation of dark and light sand in the photo, has for some management programs become the standard for identifying shoreline position. This wet/dry line has been argued to be consistent with MHW (mean high water) or other datum, though it has been difficult examine this hypothesis over a large spatial domain with historic data sets. One such investigation is found in Judge, Overton and Fisher (2001). In this paper, we will present and analyze comparisons of the position of the wet/dry line to contour based or datum derived shoreline positions using 1998 controlled aerial photography. Three locations in North Carolina will be highlighted allowing for spatial variation in shoreline characteristics. In addition, as technological advances (e.g., LIDAR, GPs) allow for the economical 3D mapping of the shoreline, the integration of contour based shoreline positions with existing wet/dry line shoreline positions for determining shoreline change is an issue. Implications of merging these data sets will be examined by comparing the resulting long-term shoreline change rate using various methods. Judge, E. K., M. F. Overton, and J. S.

Currently, about 350,000 structures are located within 500 feet of the open-ocean and Great Lakes shorelines. This accentuates the importance of understanding shoreline change processes, particularly for use in forecasting future shoreline changes. During the past 20 or so years, procedures used to conduct erosion mapping and analyses have changed significantly. What was once an exercise involving manual cartographic techniques has evolved into a highly automated computerized process. A key milestone was the incorporation of GIS into the compilation and analysis of erosion rate data in the early 1980s. This development made possible low-cost and accurate rectification of aerial photography, and provided an efficient means to overlay historical and current shoreline position data. Moreover, the use of GIs provided cost- and time-efficient methods to assess source data accuracy. Importantly, the use of GIs techniques demonstrated conclusively that historical NOS T-sheets were an accurate and valuable source for use in long-term historical shoreline change studies. During the past ten years more sophisticated methods have been used to develop and compile shoreline and erosion data. For example, global positioning systems surveys and soft-copy photogrammetry have been used increasingly to collect and/or process shoreline position data. Advances in LIDAR technology are also showing promise as a cost-efficient means to collect shoreline location data.

Along with an understanding of wave and water-level processes, these data are being used to derive coastal hazard maps for various counties. Historical shoreline mapping was carried out using digitized National Ocean Service Topographic Surveys (NOS T-sheets) from 1927, 1955 and 1953. Additional shoreline positions were derived from 1985/1986 U.S. Geological Survey topographic maps, 1994 digital orthophoto quadrangles, aerial photography from 1976, 1982, 1991, 1986, 1998, 2001, and from 1997 and 1998 LIDAR data. Analyses of the shoreline data show little evidence for either long-term net coastal recession or accretion. Instead, the shoreline data reveals that the coast responds episodically to occurrences of major storms that produce large waves that are coincident with high water levels. Furthermore, these processes tend to be enhanced during the El NiNo/Southern Oscillation (ENSO) climate phenomena, which result in highly localized hotspot erosion at the southern ends of littoral cells and with net accretion at the northern ends. Thus, the Oregon coast undergoes periods of both localized and widespread erosion, the redistribution of the eroded sediments along the coast, followed by intervening periods during which the beaches and dunes rebuild. Incorporating analyses of extreme waves and water levels combined with the historical shoreline data, the Oregon Department of Geology and Mineral Industries are using this information to derive estimates of potential future coastal erosion based on various extreme event scenarios for dune and bluff backed shorelines. These estimates are being used to establish coastal hazard zones, important to coastal planners for the safe establishment of properties and infrastructure.

Away from inlets, the surveyed dune crest defines the baseline. In developed areas, however, dunes are commonly absent or modified by structures and a hypothetical dune crest is projected to establish an equivalency in sediment volume as an adjacent undisturbed beach profile geometry. In 1993, SC OCRM and USGS established a beach-monitoring program to document the morphology and sand volume within the beach systems of South Carolina. In 2000, this program adopted DGPS-based survey methods linking an ATV mounted DGPS rover and a jet zodiac-based fathometer system across the surf zone. Surveys are run annually and elevation, morphologic features and sand volumes are determined within a GIs In 1999, the USGS and SC Sea Grant Consortium initiated a regional coastal erosion study defining the geologic framework of the beach, shoreface and inner shelf of northern SC. Rocky outcrops and non-mobile substrate are common within the intertidal beach, surf zone, shoreface and inner shelf of the region. These substrates are observed to disrupt beach profile geometry and modify alongshore and on-offshore sediment dispersal pathways. Regulatory policy in many developed areas is based on sediment volumes within the active beach, which is observed to be strongly influenced by geologic framework. This highlights the importance of merging shoreline and regional framework mapping in analyzing shoreline behavior.

Most of their feeding takes place in the northern Pacific Ocean with opportunistic feeding taking place during their migrations and residence on the breeding grounds. The concentrations of organochlorines and trace elements were determined in tissues and stomach contents of juvenile gray whales that were taken on their Arctic feeding grounds in the western Bering Sea during a Russian subsistence harvest. These concentrations were compared to previously published data for contaminants in gray whales that stranded along the west coast of the US during their northbound migration. Feeding in coastal waters during their migrations may present a risk of exposure to toxic chemicals in some regions. The mean concentration (standard error of the mean, SEM) of capital sigma PCBs [1400 (130) ng/g, lipid weight] in the blubber of juvenile subsistence whales was significantly lower than the mean level [27 000 (11 000) ng/g, lipid weight] reported previously in juvenile gray whales that stranded in waters off the west coast of the US. Aluminum in stomach contents of the subsistence whales was high compared to other marine mammal species, which is consistent with the ingestion of sediment during feeding. Furthermore, the concentrations of potentially toxic chemicals in tissues were relatively low when compared to the concentrations in tissues of other marine mammals feeding at higher trophic levels. These chemical contaminant data for the subsistence gray whales substantially increase the information available for presumably healthy animals.

This work examined the environmental factors associated with 3 separate wintertime H. triquetra blooms in the shallow tidally mixed Newport River estuary, North Carolina, USA. During 2 of the blooms in 1982 and 1983, the estuary was sampled from a fixed, single location every hour for 14 d. During the third study, the estuary was sampled at 9 fixed locations over its entire length each week from late December 1997 through March 1998. This time period included the formation and decline of the H. triquetra bloom. Barometric pressure, precipitation, photosynthetically active radiation, salinity, temperature, nutrient concentrations, and chl a were measured in each study. During the 1997-1998 study, pigments were analyzed using HPLC to characterize the phytoplankton assemblages and the dominant dinoflagellates in each sample were counted. The prevailing environmental conditions associated with the wintertime blooms were largely the result of atmospheric forcing. Low pressure systems moved through the study area at 3 to 4 d intervals and were accompanied by low ambient air temperatures and regular rainfall. Runoff following the rainfall events supplied inorganic nutrients critical for bloom initiation and development. It also created a mesohaline frontal zone in the middle portion of the estuary with salinity and hydrodynamic conditions favorable for H. triquetra growth. Here, the H. triquetra bloom reached its maximal development with chl a levels >100 mu g l super(-1) and cell densities between 1 and 6 proportional to 10 super(6) l super(-1). As the H. triquetra bloom developed, nutrient inputs from the river became insufficient to meet growth demand and H. triquetra began feeding mixotrophically, supplementing its nutritional requirements and reducing competition from co-occurring dinoflagellates. Cloud cover associated with the low pressure systems transiently limited H. triquetra growth as did low temperatures. More importantly though, low temperatures limited micro- and macrozooplankton populations to such an extent that grazing losses were minimal. Hence, in order to bloom, H. triquetra optimizes a suite of factors including low grazing pressure, increased nutrient inputs, alternative nutrient sources, and favorable salinity and hydrodynamic conditions, as well as the negative factors of temperature-limited growth, short day lengths, and periods of transient light limitation.

In an initial time-intensive study, the shallow, tidally mixed Newport River estuary, North Carolina, USA, was sampled from a fixed point located in the middle of the estuary every 2 h for 2 wk during the development of an H. triquetra bloom. The objective of this study was to investigate how short-term, high-frequency changes in temperature, light and salinity affected diel and interday cell division patterns and in situ growth rates of H. triquetra. During this study, phytoplankton samples were preserved in buffered formaldehyde and mitotic indices determined by acridine orange staining. The diel division pattern showed a nocturnal maximum between 23:00 and 05:00 h with reduced division during the day, a pattern characteristic of most dinoflagellates. The relative proportion of binucleate cells present during the day was influenced by interday variations in total irradiance, increasing during 2 of the 3 periods when there were 3 or more consecutive high light days (>28 E m super(-2) d super(-1)). Approximately 40% of the overall variation in interday division rates could be accounted for by differences in daily irradiance. The interday light differences were largely due to well-developed atmospheric frontal systems that brought increased cloud cover to the study area at regular 3 to 4 d intervals. The initial study, however, was of insufficient length to determine if the transient day-to-day light limitation could significantly affect seasonal bloom formation. A second longer-term, spatially intensive study was therefore undertaken to assess the relative importance of the incident light levels and nutrient inputs in controlling H. triquetra bloom initiation. During the second study, the estuary was monitored for photosynthetically active radiation (PAR), salinity, temperature, inorganic nutrients and cell densities of H. triquetra at 9 locations every wk from 23 December 1997 to 27 March 1998. Maximal H. triquetra bloom formation occurred during a 2 wk period when daily incident light levels were at or near the annual low. This suggested that H. triquetra is well adapted for utilizing low light levels and that variation in in situ growth rates in response to daily changes in PAR had little effect on bloom development. Instead, bloom initiation began with inputs of nitrogen-rich water following a runoff event, indicating that nutrient inputs are much more important in controlling bloom development than is light.

To test this hypothesis, I reconstructed the phylogeographic history of the desert fish Utah chub (Gila atraria) by examining 16 populations that span the natural distribution of this species across the Bonneville Basin and upper Snake River. I compared mitochondrial control region sequences (934 bp) among 77 individuals revealing 24 unique haplotypes. Geographic and phylogenetic relationships among haplotypes were explored using parsimony, maximum likelihood, nested clade analysis, and analysis of molecular variance. I found that G. atraria is composed of two distinct clades that represent an early Pleistocene split between the upper Snake River and Bonneville Basin. Within each of these clades, geographic structuring was highly concordant with the hydrological history of late Pleistocene Lake Bonneville and the upper Snake River, suggesting that glacial-induced shifts in climate and unpredictable geological events have played a major role in shaping genetic subdivision among populations. To examine the effects of vicariant events on phenotypic divergence among Utah chub populations, I mapped chub life histories to the control region haplotype network. I found a nonrandom association between haplotypes and life-history phenotypes. These results suggest that historical events responsible for population fragmentation may have also contributed to phenotypic shifts in life histories, both indirectly by limiting gene flow among populations and directly by altering the selective environments where populations persisted.

One of the current sentinel organisms, the sea mussel (Mytilus californianus), has shown minimal or undetectable toxicity during some local bloom events. As a critical step in assuring the accuracy of DA determinations in E. analoga, we have developed and validated a highly efficient extraction protocol that yields toxin recoveries of 97 plus or minus 2.9%. We also determined by HPLC-UV and receptor binding assay, with confirmation by LC-MS/MS, that sand crabs accumulated measurable amounts of DA during toxic Pseudo-nitzschia blooms, while the sea mussel showed no detectable toxin. In addition, a comparison of inter-animal variability in DA content revealed values ranging from ca. 0.5 to 5 mu g DA g super(-1) tissue and no consistent trend with size class, based on either animal weight or length. These data on the toxicity of individual animals will be useful in designing an appropriate sampling strategy for monitoring DA and, importantly, indicate that sand crabs do not appear to progressively bioaccumulate DA with age.

AN - 1665492769; 5398861 AB - Recent studies suggest that mortality of undersized fishes escaping through trawl codends may range from 0 to 100%, with mortalities of 10 to 30% being common. These values may be low, as they do not account for fishes which become behaviorally compromised by their passage through the trawl and ultimately succumb to predators. The goal of this study was to simulate in the laboratory the stressors associated with trawl passage and determine if they degrade the behavioral capabilities of juvenile walleye pollock Theragra chalcogramma to avoid predation. In the first of 2 experiments, groups of Age 1 yr+ walleye pollock were subjected to 3 treatments: (1) controls: no stressor; (2) swim/escape: forced swimming for 90 min at 0.33 m s super(-1) in a towed net, followed by escape through 8 cm square mesh; (3) swim/crowd/escape: forced swimming followed by 3 min of crowding, followed by escape. To evaluate the effect of these treatments on pollock behavior, a sablefish Anoplopoma fimbria (48 to 53 cm) was placed in an observation arena with the group and pollock anti-predator behavior was quantified. Beginning immediately after simulated trawling and for up to 24 h afterwards, pollock exposed to both trawl-stressor treatments were less likely to avoid the predator than controls, allowing it to approach closer. They were also less able to form a cohesive shoal, and in the case of the swim/crowd/escape treatment, swam more slowly than control fish. To determine if trawl-stressed fish are more vulnerable to predation, in a second experiment I mixed control and swim/crowd/escape pollock together and then subjected them to predation by a 48 to 60 cm lingcod Ophiodon elongatus, observing the behavior and enumerating the number of pollock consumed in each treatment. Lingcod concentrated attacks upon solitary individuals or those straggling behind the shoal, were more likely to lunge at pollock that did not move away when approached, and were more successful the closer the pollock at lunge initiation. As a result, trawl-stressed pollock were consumed in greater numbers than controls. On the basis of these results, it is reasonable to expect that juvenile walleye pollock passing through trawls suffer behavioral deficits, subjecting them to elevated predation risk. If this is a generic effect, these results suggest that there may be a significant bycatch associated with many commercial trawl fisheries which is generally unrecognized, unmeasured, and unaccounted for in current stock-assessment models.

It varied, however, with habitat type. Fish residing offshore had higher E sub(wb) than fish residing inshore of the frontal regions. Age 0 year walleye pollock E sub(wb) changed in a non-linear fashion with fish size, with larger juveniles typically having higher E sub(wb). Size thresholds were identified at which the relationship between age 0 year walleye pollock E sub(wb) and L sub(S) changed. One such threshold was found at 46 mm where E sub(wb) reached a local minimum. Another threshold was found at 80 mm beyond which E sub(wb) tended to remain constant with size. Overall mass-length and E sub(wb)-length residuals were highly correlated with each other (r=0.73, P[Lt] 0.0001). The slope of the regression, however, was higher for smaller fish. Possible mechanisms are proposed to explain the observed ontogenetic variation in nutritional status and the role of age 0 year walleye pollock late summer E sub(wb) on survival over their first critical winter of life.

AN - 1665486887; 5398858 AB - Processes affecting reef fish populations are likely to vary with spatial scale, but there have been few attempts to determine whether predictions generated by small-scale experiments are manifested at larger spatial scales. Our goal in this study was to determine if patterns of microhabitat use measured in small-scale experimental manipulations scaled-up and allowed predictions of among-reef patterns of abundance across larger spatial scales. Manipulations of algal biomass in artifically created 1.5 m super(2) plots indicated that patches of Sargassum filipendula supported greater numbers of slippery dick Halichoeres bivittatus than those with an equal biomass of Zonaria tournefortii, or than patches with an equal mix of S. filipendula and Z. tournefortii. Scaling up and manipulating S. filipendula and Z. tournefortii abundance in 100 m super(2) sections of reef produced results qualitatively similar to the small-scale experiments; fish densities varied as a function of S. filipendula mass. Larger scale surveys of fish densities and algal biomass on large reefs separated by 1 to 30 km showed positive associations between fish density and S. filipendula biomass. For the reefs that we studied, our small-scale experiments scaled up and predicted large-scale patterns of abundance on reefs in the South Atlantic Bight.

Habitat equivalency analysis is a technique through which the impacts due to the spill and the benefits of restoration are quantified; both are quantified as habitat resources and associated ecological services. The goal of the analysis is to determine the amount of restoration such that the services lost are offset by services provided by restoration. In this paper, we first describe the habitat equivalency analysis framework. We then present an oil spill case from coastal Louisiana, USA, where the framework was applied to quantify resource impacts and determine the scale of restoration. In the Louisiana case, the trustees assessed impacts for oiled salt marsh and direct mortality to finfish, shellfish, and birds. The restoration project required planting salt-marsh vegetation in dredge material that was deposited on a barrier island. Using the habitat equivalency analysis framework, it was determined that 7.5 ha of the dredge platform should be planted as salt marsh. The planted hectares will benefit another 15.9 ha through vegetative spreading resulting in a total of 23.4 ha that will be enhanced or restored as compensation for the natural resource impacts.

V. Knorr cruise in the Black Sea indicate that CFC-11 is non-conservative relative to CFC-12 in the strongly reducing anoxic waters. A multi-layer model combining horizontal/vertical renewal and vertical diffusion processes was tuned to the distributions of CFC-12 and salinity in suboxic and anoxic waters and used to estimate the residence times of subsurface waters and first-order in situ removal rate constants for CFC-11. The model-calculated residence times were similar to 5yr in the suboxic zone (80-120m) and increased to similar to 625yr at 500m. The first-order CFC-11 in situ removal coefficients were 0.52 plus or minus 0.19yr super(-1) for the depth range 160-480m. Based on the observed CFC-12 concentrations, the residence time of cold intermediate layer water ( similar to 50-100m) was estimated to be <5yr. The residence time of the deep water (100-450m) in the Sea of Marmara was estimated to be 12-19yr using a box model tuned to CFC-12, implying an in situ oxygen utilization rate of 10-18 mu molkg super(-1)yr super(-1).

The four primary airstreams that compose these cyclones, the warm conveyor belt (WCB), cold conveyor belt (CCB), dry airstream (DA), and post cold front (PCF) airstream, exhibit characteristic trace gas mixing ratios that vary seasonally. The present study compares ozone and CO mixing ratios measured in these four airstreams during spring 1996 and late summer/early autumn 1997. The three main influences on this seasonal variation of ozone and CO are surface emissions heterogeneity, photochemistry, and stratosphere/troposphere exchange efficiency. The more southerly springtime cyclone tracks account for nearly 50% of the increase of lower troposphere CO from late summer/early autumn to spring. The remainder of the variation is due to the seasonal cycle of background CO. Stratosphere/troposphere exchange occurs in every DA; however, the seasonal cycle of ozone in the lowermost stratosphere allows greater quantities of ozone to enter the troposphere during spring. Net photochemical ozone production occurs in the late summer/early autumn WCB at all levels and in the lower troposphere PCF. In contrast, springtime net ozone production appears absent from all airstreams, with the CCB influenced by ozone destruction. Ozone and CO are greater in spring, but the relative mixing ratios between airstreams are roughly the same in both seasons. NO sub(x)/CO emissions ratios vary across the midlatitudes according to socioeconomic factors. It is expected that the emissions variation influences the ozone production efficiency of the cyclone airstreams that draw from these regions. JF - Journal of Geophysical Research. D.

The technique, known as terminal restriction fragment length polymorphism (T-RFLP), employs the polymerase chain reaction (PCR) using a primer pair that targets 2 highly conserved regions of the gene that encodes for the 16S small subunit of the bacterial ribosome. Each primer is 5' labeled with a different fluorescent dye, which results in each terminus of the resulting amplicon having a distinguishable fluorescent tag. The amplicon is then digested with a series of 6 restriction endonucleases, followed by size determination of the 2 labeled terminal fragments by capillary electrophoresis with laser-induced fluorescence detection. Comparison of the lengths of the full set of 12 terminal fragments with those predicted based on analyses of GenBank submissions of 16S sequences leads to presumptive identification of the pathogen to at least the genus, but more typically the species level. Results of T-RFLP analyses of genomic DNA from multiple strains of a number of fish bacterial pathogens are presented. The assay is further demonstrated on fish kidney tissue spiked with a known number of cells of Flavobacterium psychrophilum where a detection limit of ca. 30 CFU mg super(-1) of tissue was estimated. A similar detection limit was observed for several other Gram-negative pathogens. This procedure was also used to detect Aeromonas salmonicida and Renibacterium salmoninarum in the kidney tissue of 2 naturally infected salmonids.

AN - 71721887; 12033233 AB - A method based on isotope dilution cold-vapor inductively coupled plasma mass spectrometry (ID-CV-ICPMS) has been developed for high-accuracy determinations of mercury in bituminous and sub-bituminous coals. A closed-system digestion process employing a Carius tube is used to completely oxidize the coal matrix and chemically equilibrate the mercury in the sample with a 201Hg isotopic spike. The digestates are diluted with high-purity quartz-distilled water, and the mercury is released as a vapor by reduction with tin(II) chloride. Measurements of 201Hg/202Hg isotope ratios are made using a quadrupole ICPMS system in time-resolved analysis mode. The new method has some significant advantages over existing methods. The instrument detection limit is less than 1 pg/mL. The average blank (n = 17) is 30 pg, which is roughly 1 order of magnitude lower than the equivalent microwave digestion procedure. The detection limit in coal is blank limited and is approximately 40 pg/g. Memory effects are very low. The relative reproducibility of the analytical measurements is approximately 0.5% for mercury concentrations in the range 10-150 ng/g. The method has been used to measure mercury concentrations in six coal reference materials, SRM 1632b (77.4 ng/g), SRM 1632c (94.3 ng/g), BCR 40 (433.2 ng/g), BCR 180 (125.0 ng/g), BCR 181 (135.8 ng/g), and SARM 20 (252.6 ng/g), as well as a coal fly ash, SRM 1633b (143.1 ng/g). The method is equally applicable to other types of fossil fuels including both crude and refined oils.

AN - 71446853; 11835155 AB - A methodology for the preparation of porous scaffolds for tissue engineering using co-extrusion is presented. Poly(epsilon-caprolactone) is blended with poly(ethylene oxide) in a twinscrew extruder to form a two-phase material with micron-sized domains. Selective dissolution of the poly(ethylene oxide) with water results in a porous material. A range of blend volume fractions results in co-continuous networks of polymer and void spaces. Annealing studies demonstrate that the characteristic pore size may be increased to larger than 100 microm. The mechanical properties of the scaffolds are characterized by a compressive modulus on the order of 1 MPa at low strains but displaying a marked strain-dependence. The results of osteoblast seeding suggest it is possible to use co-extrusion to prepare polymer scaffolds without the introduction of toxic contaminants. Polymer co-extrusion is amenable to both laboratory- and industrial-scale production of scaffolds for tissue engineering and only requires rheological characterization of the blend components. This method leads to scaffolds that have continuous void space and controlled characteristic length scales without the use of potentially toxic organic solvents.

Using short-form data from the 1990 & 2000 censuses, we explore changes in the size & distribution of the Latino population. The most important shifts in the Hispanic population are the continued increase of the Latino population in the US, the significant growth of Hispanic population who identify as "other" Latino, & the growing importance of the Midwest & South as popular receiving areas for Latinos. Additionally, our comparison of household composition over the ten-year period shows little change. We offer potential explanations, both substantive & methodological, for these important transitions in the Latino population over the decade. 4 Tables, 68 References.

Population growth in the 1990s was not only higher than in recent decades, it was also more geographically widespread, with more states, counties, & cities experiencing population gains. This paper examines population growth during the 1990s for a variety of geographic levels, including regions, divisions, states, metropolitan areas, counties, & large cities. It then compares growth rates for the 1990s with earlier decades to provide a historical context for present-day trends in population growth & decline. Finally, it discusses how differential population growth in recent decades has resulted in a new form of population distribution in the US. 8 Tables, 2 Figures. Adapted from the source document.

In these areas either the US Postal Service or Census Bureau staff delivered the census questionnaire. In urban & suburban areas of the country, the US Postal Service delivered the census questionnaires 13-15 Mar 2000. The addresses in these areas are predominately city style; house number & street name. In more rural areas of the country with predominately non-city style addresses, Census Bureau staff delivered the questionnaire during Mar 2000. Respondents completed their census questionnaires & returned them through the mail. Returns from these housing units are classified as self-response. Respondents who did not complete & return their census questionnaire by 18 Apr 2000 were interviewed during the nonresponse follow-up operation (personal visit interview). This paper will examine the demographic characteristics of persons enumerated on the mail return questionnaire (self-response) & the persons enumerated during the nonresponse follow-up operation (personal visit interview). 7 Tables, 11 References.

We use the global cooling and drying of the atmosphere that was observed after the eruption of Mount Pinatubo to test model predictions of the climate feedback from water vapor. Here, we first highlight the success of the model in reproducing the observed drying after the volcanic eruption. Then, by comparing model simulations with and without water vapor feedback, we demonstrate the importance of the atmospheric drying in amplifying the temperature change and show that, without the strong positive feedback from water vapor, the model is unable to reproduce the observed cooling. These results provide quantitative evidence of the reliability of water vapor feedback in current climate models, which is crucial to their use for global warming projections.

S. West Coast/Alaska Tsunami Warning Center AN - 52020423; 2003-019266 AB - The automatic earthquake processing system developed at the U.S. West Coast/Alaska Tsunami Warning Center, known as EarlyBird, provides the center with fast, reliable, and accurate locations and magnitudes for worldwide, regional, and local earthquakes. EarlyBird automatically and interactively computes MS, Ml, Mb, Mw, and Mwp magnitudes. It provides an easy method for interactive adjustment of automated P-picks and magnitude determinations during an event. For the time period July 2001 through December 2001, EarlyBird automatically located 94% of worldwide earthquakes magnitude 6 or greater (64 of 68) and 100% of Alaska, British Columbia, and U.S. west coast earthquakes over magnitude 5 (34 of 34). Missed events often occurred in the coda of previous events leading to inaccurate automatic P-picks. Locations of earthquakes over magnitude 6 averaged less than 0.7 degrees from the USGS National Earthquake Information Center's Preliminary Determination of Epicenter reports.

These can be grouped into four types: (1) Circular "pockmarks" 100-200 in diameter and up to5 meters deep within the mud zone on the north and northwest seaward flanks of the bank in depths of 220 to 300 m; (2) streams of gas bubbles at the top of the bank (<100 m) emanating from mudstone outcrops; (3) A 2X0.5 km-area of acoustically reflective material south of Heceta Bank in 500 meters of water characterized by extensive carbonate pavements and patches of Calyptogena pacifica (S. Goffredi, pers. commun.), and (4) a 100-m long carbonate ridge oriented NW-SE parallel to the regional left-lateral strike slip direction described by Goldfinger et al. (1992). Most of the pockmarks had active areas characterized by microbial mats and gas bubbling. Solemya sp. valves and a live specimen of Conchocele bisecta were recovered from a pockmark on the upper continental slope northwest of the bank. In addition to the more obvious seeps characterized by carbonate pavements, endosymbiotic fauna and (in some cases) gas bubbles, there were numerous other sightings of small patches of (apparent) microbial mats. The origin of the methane is problematic. However, Collier and Lilley (1992) reported carbon isotope values from a methane sample from a shallow water pockmark on the southern Oregon shelf consistent with a deep thermogenic source. The overall impression is that methane seepage is very common in the Heceta Bank and that it could be an important component of the geologic and biologic processes of the upper slope and outer shelf region.

S. Geological Survey conducted high-resolution multibeam mapping of portions of the seafloor of southern Puget Sound to assess the effects of the 28 February, 2001 Nisqually earthquake. Within a month of the earthquake a joint cruise was organized to examine the submerged portions of the Duwamish River delta in Seattle, the Puyallup River delta in Tacoma, and the Nisqually River delta, nearby the earthquake epicenter. Although no submarine failures were found on the Nisqually River delta, a variety of failures were observed on the Puyallup and Duwamish River deltas, some of which may be related to the earthquake. New bathymetric data along the Puyallup River delta in Commencement Bay show a few known historic submarine failures, many older looking failures, and several fresh features that may be related to the recent earthquake. Major submarine failures from 1894 along the southwestern delta front and from 1992 along the central delta front, as well as several other failures are easily identified in the new data. Features, including an arcuate-shaped headscarp and numerous craters, interpreted as expulsion pits, may be a result of the earthquake. The headscarp has about 2 meters of offset and is about 200 m wide. The craters are as much as 25 m across and 0.5 m deep and are the type of features that might be expected after severe ground shaking. Also on the Puyallup Delta is a marine disposal mound that has been cut by several landslides, some as large as 100 m wide, 15 m deep, and hundreds of meters long. The Duwamish River delta and the margins of Elliott Bay also have numerous submarine failures that are evident in the multibeam data. The delta front has several failures, ranging in width from less than 40 m to more than 300 m and in length from less than 100 m to more than 500 m. The heads of these submarine landslides are in less than 15 m of water and within a few tens of meters from the Seattle Port facility. Along the north side of Elliott Bay are a fresh looking landslide scar and a large crater. The crater has a 6-m wide floor, is 1.6 m deep, and has a raised rim.

Information obtained from such analysis, which includes temporal chemical-concentration profiles in various media, mass distribution, and intermedia chemical mass fluxes, can be used for subsequent exposure and risk analyses. The software architecture of the environmental simulator for multimedia environmental distribution of toxics (Mend-Tox) system is presented with emphasis on features that allow for rapid scenario design and analysis of dynamic chemical partitioning in the environment. Mend-Tox is a hybrid model that consists of both uniform (air, water, suspended solids, vegetation, biota, suspended solids, and atmospheric aerosols) and nonuniform (soil and sediment) environmental compartments. The model structure is described in a companion paper (Part I). The modular structure of the system provides for flexibility of model design, implementation of a variety of simulation scenarios, maintenance and reusability of model components, and ease of future improvements. The applicability of Mend-Tox is illustrated for the distribution of polycyclic aromatic hydrocarbons (PAHs) and their nitro-PAH daughter products in the Los Angeles Basin, a retrospective analysis of polychlorinated biphenyls in Lake Michigan, and the partitioning behavior of selected volatile organic compounds. The level of predictive multimedia analysis represented by these examples yields very reasonable agreement with reported measurements.

The hybrid modeling framework consists of both uniform (air, water, suspended solids, vegetation, biota, suspended solids, and atmospheric aerosols) and nonuniform (soil and sediment) environmental compartments. The interactive system of model equations for the uniform compartments (ordinary differential equations) and nonuniform compartments (1D partial differential equations) must be solved simultaneously to ensure conservation of mass. In order for the approach to be of practical use, parameter input could be minimized through the use of theoretical or empirical description of intermedia transfer processes and estimation methods for associated intermedia transport parameters. Environmental problems are complex, and there are numerous possible multimedia analysis scenarios that may be of interest. Therefore, efficient and user-friendly implementations of such models are essential if multimedia analysis is to become a standard environmental tool.

It also recommends process studies of air-sea gas exchange, in order to obtain more accurate estimates of CO (sub 2) transfer between the atmosphere and oceans. Models are essential tools for understanding the distributions and fluxes of CO (sub 2) in the atmosphere and oceans. We recommend observations and modeling efforts to enhance the skills of models used for this purpose. An ultimate product of the observations, modeling efforts and complementary process studies will be improved projections of the trajectory of the atmospheric CO (sub 2) increase.

This joint effort by the geophysics groups at the University of Texas at El Paso (UTEP), U.S. Geological Survey (USGS), and National Oceanic and Atmospheric Administration (NOAA) (with support from the National Imagery and Mapping Agency [NIMA]), is an outgrowth of the new geoscientific community initiative called Geoinformatics (www.geoinformaticsnetwork.org). This dominantly geospatial initiative reflects the realization by Earth scientists that existing information systems and techniques are inadequate to address the complex scientific and societal issues that we must confront. Currently, the lack of standardization and chaotic distribution of available geoscience data, a lack of documentation about them, and the lack of easy-to-use access tools and computer codes for their analysis are major obstacles for scientists, government agencies, and educators alike. A good example of the type of activities envisioned within the context of Geoinformatics is the construction, maintenance, and growth of a public domain gravity database and development of the software tools needed to access, use, and expand it. A product such as this is far more than a high-quality database; it is a data system for a specific type of geophysical measurement. The effort we are launching can thus be thought of as the first step in building a data system for gravity measurements, and it builds on existing collaborative efforts. This compilation effort will result in the additions to and refinement of the benchmark national database that is released publicly via NOAA's National Geophysical Data Center.

AN - 19424557; 5392488 AB - A regression model (RivR-N) was developed that predicts the proportion of N removed from streams and reservoirs as an inverse function of the water displacement time of the water body (ratio of water body depth to water time of travel). When applied to 16 drainage networks in the eastern U.S., the RivR-N model predicted that 37% to 76% of N input to these rivers is removed during transport through the river networks. Approximately half of that is removed in 1st through 4th order streams which account for 90% of the total stream length. The other half is removed in 5th order and higher rivers which account for only about 10% of the total stream length. Most N removed in these higher orders is predicted to originate from watershed loading to small and intermediate sized streams. The proportion of N removed from all streams in the watersheds (37-76%) is considerably higher than the proportion of N input to an individual reach that is removed in that reach (generally <20%) because of the cumulative effect of continued nitrogen removal along the entire flow path in downstream reaches. This generally has not been recognized in previous studies, but is critical to an evaluation of the total amount of N removed within a river network. At the river network scale, reservoirs were predicted to have a minimal effect on N removal. A fairly modest decrease (<10 percentage points) in the N removed at the river network scale was predicted when a third of the direct watershed loading was to the two highest orders compared to a uniform loading.

An automated, operational algorithm called the Precipitation Processing System (PPS) uses reflectivity data to estimate precipitation accumulations. The utility of these estimates has yet to be quantified in the Intermountain West during winter months. The accuracy of precipitation estimates from the operational PPS during cool-season, stratiform-precipitation events in Arizona is examined. In addition, a method, with the potential for automation, is developed to improve estimates of precipitation by calibrating infrared data (10.7- mu m band) from Geostationary Operational Environmental Satellite-9 using reflectivity-derived rainfall rates from WSR-88D radar. The "multisensor" approach provides more accurate estimates of rainfall across lower elevations during cool-season extratropical storms. After the melting layer has been manually identified using volumetric radar reflectivity data, reflectivity measured in or above it is discarded. Melting-layer heights also indicate the altitude of the rain-snow line. This information is used to delineate and map frozen versus liquid precipitation types. Rain gauges are used as an independent, ground-based source to assess the magnitude of improvements made over PPS rainfall products. Although the technique is designed and evaluated over a limited area in Arizona, it may be applicable to many mountainous regions.

Developed to complement the existing gauge-based bias correction procedures used in the National Weather Service (NWS), the proposed procedure is a generalized local bias estimator that may be used under varying conditions of rain gauge network density and types of rainfall. To arrive at the procedure, the correction problem is formulated as a space-time estimation of radar and bin-averaged gauge rainfall from radar rainfall data and rain gauge measurements, respectively, at all hours up to and including the current hour. The estimation problem is then solved suboptimally via a variant of exponential smoothing. To evaluate the procedure, parameter estimation and true validation were performed using hourly radar-rainfall and rain gauge data from the Arkansas-Red Basin River Forecast Center (ABRFC) area. The results indicate that the proposed procedure is generally superior to mean field bias correction, and that the improvement is particularly significant in the cool season.

Two replicates of five representative habitats were sampled in most estuaries: eelgrass (Zostera marina), unvegetated areas adjacent to eelgrass, macroalgae, (primarily Ulva lactuca), unvegetated areas adjacent to macroalgae, and tidal marsh creeks. Fish were sampled every two weeks, May through October 1995 and 1996, with a beam-trawl (1-m width, 3-mm mesh net). Abundance of YOY winter flounder was highest in the Navesink River estuary and similar between years, but was significantly lower and differed between years in the Great Bay-Little Egg Harbor and Hammonasset River estuaries. Annual temperature differences appear to influence estuary use by YOY. In the years and estuaries studied, where habitat-related differences in abundance were significant, YOY were found in higher densities in unvegetated areas adjacent to eelgrass. The exception was in the Hammonasset River in 1995 when densities were higher in eelgrass. We conclude that the type of habitat most important to YOY winter flounder varies among estuaries and as a result, care should be taken in defining EFH, based only on limited spatial and temporal sampling.

Young-of-the-year winter flounder Pseudopleuronectes americanus and tautog Tautoga onitis were grown in short-term caging experiments conducted during 1994 and 1995 within 3 geographically distinct estuarine systems in the NE of the USA: the Hammonasset River along the Connecticut coast of Long Island Sound, the Navesink River located in the Hudson-Raritan Bay estuary in northern New Jersey, and Great Bay-Little Egg Harbor estuary in southern New Jersey. Fish were caged in each of 5 habitat types including: eelgrass, macroalgae, unvegetated areas adjacent to eelgrass, unvegetated areas adjacent to macroalgae, and tidal marsh creeks. White muscle tissue RNA concentration ( mu g per mg wet tissue wt) was measured in winter flounder and tautog recovered from the cages and compared to instantaneous growth rate measurements of these same fish. RNA concentration was significantly correlated with growth rate measured as length (r = 0.83) and weight (r = 0.79) in winter flounder and length (r = 0.69) and weight (r = 0.73) in tautog. In most cases, estuary- and habitat-specific differences in growth rate, as determined by RNA concentration, were similar to those determined by measuring instantaneous growth. These results validate the use of RNA concentration as an indirect measure of growth in young-of-the-year winter flounder and tautog.

AN - 18418080; 5403201 AB - More recent and extensive food web studies have questioned some of the prevailing paradigms of food web theory. Yet with few exceptions, most food webs and associated metrics are reported for freshwater or terrestrial systems. I analyzed the food web of the Northeast US Shelf ecosystem across a large spatial and temporal extent. This speciose food web exhibits a predator:prey ratio (0.95) and percentage of intermediate species (89%) similar to most other food webs. Other statistics, such as the percentage of omnivory (62%), percentage of cannibalistic species (31%), number of cycles (5%), and the total number of links (L; 1562) and species (S; 81) are similar to more recent and extensively studied food webs. Finally, this food web exhibits a linkage density (L/S; 19.3), connectivity (C; 48.2%), and Lyapunov stability proxy (S arrow left C; 39.1) that are an order of magnitude higher than other webs or are disproportionate to the number of species observed in this system. Although the exact S and C relationship is contentious, the connectivity of food webs with more than 40 species is approximately 10%, which is very different from the near 50% observed for this ecosystem. The openness of marine ecosystems, lack of specialists, long lifespans, and large size changes across the life histories of many marine species can collectively make marine food webs more highly connected than their terrestrial and freshwater counterparts, contrary to food web theory. Changes in connectivity also have ramifications for ecosystem functioning and Lyapunov stability. The high connectivity of this food web and the mathematical determinants for stability are consistent with the weak nature of species interactions that have been observed and that are required for system persistence. Yet the historically high exploitation rates of marine organisms obfuscate our understanding of marine food web stability. It is possible that marine food webs are inherently very different from their terrestrial or freshwater counterparts, implying the need for modified paradigms of food web theory.

Each of 549 handled seals was matched to a control seal of the same age, sex, location, and year. Handling included instrumentation with telemetry devices (n = 93), blood sampling (n = 19), and tagging (n = 437). No significant differences were found between handled seals and their controls in one-year resighting rates, observed migration rates, or condition. Resighting rates of handled and control seals were high (80%-100%). Available sample sizes were sufficient to detect reasonably small (9%-20%) differences in resighting rates had they existed among instrumented or tagged seals and controls ( alpha = 0.05, power = 0.90). Too few seals were captured for blood sampling to detect even large differences in their resighting rates. However, blood samples were drawn from most instrumented seals, and there was no indication that this larger group suffered harmful effects. Duration of restraint during flipper tagging had no effect on subsequent probability of resighting. Our analysis suggests that conservative selection procedures and careful handling techniques have no deleterious effects on Hawaiian monk seals.

Part II: Multiple Boundaries and Convective Initiation AN - 18299349; 5353484 AB - A dryline that occurred on 16 May 1991 within a synoptically active environment is examined in detail using research aircraft, radar, surface, satellite, and upper air observations. The work focuses on multiple boundaries in the dryline environment and initiation of tornadic storms in two along-line areas. Aircraft measurements in the boundary layer reveal that both the east-west extent of moisture gradients and the number of regions containing large moisture gradients vary in the along-dryline direction. Aircraft penetrations of thinlines observed in clear air return from radar reveal that all thinlines are associated with convergence and a moisture gradient, and that more distinct thinlines are associated with stronger convergence. However, significant moisture gradients are not always associated with either thinlines or convergent signatures. Convective clouds on this day formed at the dryline rather than significantly east of the dryline. The three thunderstorm cells that occurred in east-central Oklahoma developed along a 20-km section of the dryline south of a dryline bulge and within a 30-min period. The storms appear to have developed in this location owing to enhanced convergence resulting from backed winds in the moist air in response to lowered pressure in the warm air to the northwest. Aircraft measurements in the boundary layer and satellite-sensed surface temperature both indicate localized warming in this area to the northwest. Farther north there was a 70-100-km segment along the dryline where few convective clouds formed during the afternoon. This coincided with a swath of cooler boundary layer air that resulted from reduced surface heating over an area that received significant thunderstorm rainfall during the previous night. A severe thunderstorm complex that developed along the Kansas-Oklahoma border was initiated at the intersection of the dryline and a cloud line that extended into the dry air. An aircraft penetration of the cloud line about 12 km from its intersection with the dryline shows convergence and deepened low-level moisture at the cloud line. The cloud field that evolved into the cloud line over a period of several hours developed over the area that had received the heaviest rainfall during the previous night.

Over seven breeding seasons, we studied the provisioning behavior of chinstrap penguins, Pygoscelis antarctica, at Seal Island, Antarctica, during parents' transition to leave broods of one or two chicks unguarded. By measuring the frequency, duration, and diel timing of foraging trips and the quantity of prey brought to chicks, we examined the extent to which variation in parents' feeding behavior could be attributed to provisioning costs which increase with chick growth. Estimates of the energy content of food loads were combined with foraging patterns and brood requirements to model parents' seasonal provisioning budget. The frequency of foraging trips increased from the guard to post-guard phase and was higher, and the seasonal effect larger, in parents with two chicks. The duration of overnight trips (~16 h) increased with seasonally increasing night length; diurnal trip duration (~8 h) showed no seasonal pattern. Birds exhibited a seasonal shift to diurnal foraging, a trend that was generally weaker in parents of smaller broods. Food loads increased with chick mass only in parents of one chick; parents of two chicks had larger but more constant food loads. Based on per trip calculations, parents foraging overnight could not have delivered to two-chick broods enough food to meet their demands unless chicks were small. Diurnal foragers (regardless of brood size) and overnight foragers with one chick could meet brood demands at chicks' peak mass. The combined daily effort of parents indicated that mated pairs on average had ample resources to meet chick demands through most of rearing. A brief period when demands could not be met was predicted in two-chick broods just before chicks were left unguarded and again as they neared fledging. Our findings suggest that penguins both increased provisioning frequency and favored foraging under higher light intensity in conjunction with increasing chick demands, tactics which required parents to leave chicks unattended. The ability to maintain intrinsic control over provisioning has bearing on how penguins may be limited by extrinsic constraints. Prey surveys conducted annually near colonies show abundant resources 10-20 km offshore with no consistent seasonal shifts in abundance. These findings support a prominent role for intrinsic factors in the foraging decisions of chinstrap penguins.

Observed travel times are the result of both environmental factors such as air or water currents and the behavior of individuals. In an effort to distinguish among these components, I developed a migration model based on an advection-diffusion equation that characterizes population movements in terms of two biologically meaningful parameters: migration rate and rate of population spread. I applied the model to travel time data from juvenile chinook salmon (Onchorhynchus tshawytscha), which were tagged during their seaward migration. The tagged fish originated from three separate evolutionarily significant units (ESUs) as classified by the U. S. National Marine Fisheries Service. The model was expanded by allowing migration and diffusion rates to vary with fish length and river flow. Variability in travel times explained by these factors was strikingly similar from year to year within ESUs, and the migratory behavior revealed by the analysis was consistent with the life-history patterns that distinguish the ESUs. The approach presented here is easily adaptable to a wide range of migratory species and may be particularly useful for predicting how at-risk populations respond to variable conditions in regulated or otherwise disturbed migration habitats.

The National Assessment of Potential Consequences of Climate Variability and Change (NAST 2001) was based on a series of regional and sector assessments. This paper is a summary of the coastal and marine resources sector review of potential impacts on shorelines, estuaries, coastal wetlands, coral reefs, and ocean margin ecosystems. The assessment considered the impacts of several key drivers of climate change: sea level change; alterations in precipitation patterns and subsequent delivery of freshwater, nutrients, and sediment; increased ocean temperature; alterations in circulation patterns; changes in frequency and intensity of coastal storms; and increased levels of atmospheric CO sub(2). Increasing rates of sea-level rise and intensity and frequency of coastal storms and hurricanes over the next decades will increase threats to shorelines, wetlands, and coastal development. Estuarine productivity will change in response to alteration in the timing and amount of freshwater, nutrients, and sediment delivery. Higher water temperatures and changes in freshwater delivery will alter estuarine stratification, residence time, and eutrophication. Increased ocean temperatures are expected to increase coral bleaching and higher CO sub(2) levels may reduce coral calcification, making it more difficult for corals to recover from other disturbances, and inhibiting poleward shifts. Ocean warming is expected to cause poleward shifts in the ranges of many other organisms, including commercial species, and these shifts may have secondary effects on their predators and prey. Although these potential impacts of climate change and variability will vary from system to system, it is important to recognize that they will be superimposed upon, and in many cases intensify, other ecosystem stresses (pollution, harvesting, habitat destruction, invasive species, land and resource use, extreme natural events), which may lead to more significant consequences.

Females mated by males with fully recovered seminal resources received significantly more sperm than those mated with males that had mated once previously, regardless of male size. No significant difference was found between the number of sperm delivered by small and large males with similar mating history. The sperm content of ejaculates from these laboratory experiments was compared to sperm received by females collected in the field. Only 11% of field-collected females received an amount of sperm as large as that delivered by the fully recovered males in our laboratory experiments. Of the field collected females, 77% received much less sperm, similar to or below the number delivered by depleted males in our laboratory experiments.

Two basic kinds of satellite-based estimates are available. Infrared data from geostationary satellite platforms such as the Geostationary Operational Environmental Satellite (GOES) can be used to infer cloud-top conditions on a continuous basis, but the relationship between cloud-top conditions and the rate of rainfall below can vary significantly. Microwave radiances are related more directly to precipitation rates, but microwave instruments are limited to polar-orbiting platforms, resulting in intermittent availability of estimates. A number of authors have made efforts to combine the strengths of both by using the microwave-based estimates to adjust the GOES-based estimates, mainly for long-term precipitation estimates at coarse spatial resolution. The self-calibrating multivariate precipitation retrieval (SCaMPR) technique represents an approach for doing the same for fine timescales and short time periods. This algorithm first selects an optimal predictor for separating raining from nonraining pixels, calibrates it to raining and nonraining areas from a Special Sensor Microwave Imager (SSM/I) algorithm, and then selects an optimal rain-rate predictor and calibrates it to the SSM/I rain rate for the raining pixels via linear regression. The performance of SCaMPR compared favorably with the autoestimator (AE) technique and GOES multispectral rainfall algorithm (GMSRA) when compared with rain gauge data for three cases. The linear correlations between the estimates and rain gauge observations were similar, but SCaMPR exhibited significantly less bias than did AE and GMSRA.

We measured fine-scale (1-10 m) distributions of nekton on the vegetated marsh surface using enclosure samplers in Galveston Bay, Texas, and used these patterns to estimate population size. Natant decapod crustaceans were abundant in the marsh; densities of juvenile brown shrimp Farfantepenaeus aztecus, white shrimp Litopenaeus setiferus, and blue crabs Callinectes sapidus were highest 1 m from the water's edge and declined rapidly to 10 m from the edge. We developed regression models to describe these fine-scale density patterns and validated the models with independent data on density distributions from two other marsh systems. We used a Geographic Information System to transfer the density models to a natural marsh landscape; the highly fragmented Elmgrove Point marsh was composed of shallow nonvegetated bottom (37.4% of the area) and Spartina alterniflora vegetation (62.6%) with similar to 15% of the vegetated area within 1 m of the marsh-water interface. We estimated that this 437-ha salt marsh complex supported populations of 16.2 million brown shrimp, 15.5 million white shrimp, and 11.3 million blue crabs. We divided the marsh complex into 39 sectors and examined relationships between nekton populations and landscape-scale patterns of marsh fragmentation. The amount of edge and the population estimates in a sector increased consistently with the amount of water up to similar to 20-25%. Nekton population declines were not apparent until the late stages of marsh disintegration (>70% open water). We also used our fine-scale density models to simulate the effects of adding creeks to a 1-ha created salt marsh of solid vegetation. For shrimp, 1-2 creeks/ha (or a comparable amount of edge) were required to reach populations equivalent to shallow nonvegetated bottom, and up to 6 creeks/ha were required to reach populations similar to those estimated for the natural marsh complex. Simulated populations of blue crabs reached levels in the natural marsh complex with the addition of fewer creeks (2-3 creeks/ha).

Fishery dependent and independent data from 1972-97 were analyzed for numbers, fishing mortality rates at age, and other parameters. A surplus production model also was applied. These show a large increase in exploitation of the red porgy and associated decline in abundance. Specific population parameters are summarized. The long-term, marked declines in recruitment, spawning stock, and catch per unit effort are consistent with severe overexploitation during a period of reduced recruitment. The current spawning stock biomass is well below that needed to support maximum sustainable yield. Fishing mortality will need to be reduced significantly to rebuild these red porgy stocks.

Rockfishes, including bocaccio and greenspotted rockfish, have been overfished and the former are at high risk for extinction. SCUBA techniques were used to implant acoustic transmitters in six greenspotted rockfish and 16 bocaccio on the flank of the Soquel Canyon in Monterey Bay, CA, so that the movements of these fish could be monitored over a three-month period in two years. Tagged greenspotted rockfish showed little vertical movement and limited horizontal movement. Bocaccio were somewhat more mobile but spent most of their time in a limited area. On occasion, individuals of both species moved longer distances. The implications of these findings on distribution and mobility for the success of marine reserves as a protective measure. The full extent of the range and periodicity of rockfish movements needs to be known in order to design an effective marine reserve for them.

Smaller fish (<300 mm) were found over flat, hard substrata and low-lying limestone reefs, while larger fish were more often caught over larger limestone and coral reef formations. Maximum total lengths, weights, and ages for males and females of different size classes are summarized. Preliminary estimates of total mortality suggest that this species is subjected to a level of fishing pressure that is cause for concern to fishery managers. Additional information on spawning habitat and times, age and length at maturity, and survival after handling is discussed. A minimum legal length is not an effective conservation measure for this species. Alternatives, such as restricting fishing activity in highly fished areas, reducing daily bag limits for recreational fishers, and introducing quotas for commercial fisheries, are likely to be more effective.

AN - 14623304; 10624245 AB - The effects of commercial fishing on habitat and non-target species were studied for the case of a scavenger fish (the longhorn sculpin) known to consume scallop fishery discards. Bottom trawl survey data and food habits of the longhorn sculpin were examined over 15 yr in areas of the Georges Bank where scallop fishing occurred and did not occur, to ascertain the importance of scallop fishery discards on longhorn sculpin populations. Opportunistic feeding on discarded scallop viscera appears to have a weak but positive effect on sculpin populations. Other factors probably also influence sculpin populations. Energy derived from fishery discards (a subsidy, in effect) may cause scavengers to become more abundant than they would be with ambient resources, or may help scavengers maintain population abundance under disturbed conditions.

Some 49% of the bottlenose dolphin strandings occurred between April and July. Strandings in the northern part of the state increased significantly in some seasons of the study period. Neonates stranded in every month except March and October and were 19.6% of the total bottlenose dolphins stranded. Some 23% of the stranded dolphins are known to have died due to human interactions (16 of these cases were caused by net entanglement).

Bycatch reduction devices (BRDs) were studied for inshore and nearshore shrimp fisheries. The extended mesh funnel and Florida fisheye BRDs were evaluated in otter trawls under different conditions. Without such devices, finfish dominated most trawl bycatches, although horseshoe crab and blue crab bycatches seasonally dominated some trawls. Ten finfish accounted for 92% of the total finfish bycatch, with commercially or recreationally valuable species comprising 7% of the catch. BRDs lowered the biomass and number of finfish compared with controls, but shrimp numbers and biomass were not affected. Seasonal, size, and other variations in finfish bycatch and shrimp catch with BRD use are discussed. Florida now requires use of BRDs in state waters.

(SECOND DRAFT SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF MARCH 1999). AN - 36419867; 9238 AB - PURPOSE: A regulatory adjustment of the fishery management plan (FMP) for Atlantic tunas, swordfish, and sharks is proposed. The target species are highly migratory species (HMS) inhabiting the Atlantic Ocean, the Gulf of Mexico, and the Caribbean Sea. The intent of the proposed actions is to reduce bycatch and bycatch mortality of sea turtles by U.S. commercial fishermen who hold permits for the catch of HMS and use pelagic longline gear in the Atlantic Ocean. Pelagic longline gear is the dominant gear used by U.S. fishermen in the Atlantic Ocean to target HMS. Furthermore, it is commonly used by vessels flying under various national flags fishing the waters of the Western Atlantic. Longline gear can be modified to target yellowfin tuna, bigeye tuna, sharks, or swordfish. However, the gear also catches other species, including sea turtles, that are not the intended target species. The proposed action would close the Northeast Distant Statistical Reporting Area to pelagic longline fishing. In addition to the area closure, the rule would require the HMS pelagic longline fleet to modify the manner in which fishing is conducted. Gangions would be required to be 10 percent longer than floatlines in sets of 100 meters or less. Additionally, gangions would be prohibited from being set within two gangion lengths of the floatlines. Corrodible hooks and/or crimps (proposed to be non-stainless steel) would be required fleetwide. In addition to these gear modifications, vessel operators in the fleet would be required to report lethal sea turtle takes within 48 hours of returning to port and to post sea turtle handling and release guidelines in the wheelhouse. Fishermen in the bottom longline fishery would be required to post sea turtle handling and release guidelines in the wheelhouse. Fishermen in the shark gillnet fishery would be required to look for sea turtles and marine mammals every 30 minutes to two hours during net checks. Any entangled animals would have to be removed from the net. The regulations concerning the shark fishery would be amended to clarify that both the observer and vessel operator would be responsible for sighting whales and contacting the National Marine Fisheries Service. POSITIVE IMPACTS: By reducing bycatch and incidental catch; the regulatory amendments would improve the sustainability of sea turtles and other HMS species. NEGATIVE IMPACTS: Certain fishery management provisions, particularly gear restrictions and the area closure, could result in economic losses to fishing interests.

We focus on the ecological role of energy storage. A physiologically based submodel describes how individual predators allocate assimilated energy among growth, reproduction, and storage. We use invasibility analyses to predict evolutionary stable strategies for energy allocation. Various proxy measures of fitness based on measurable biological quantities, such as average population size or average per-capita fecundity, fail to predict evolutionary stable strategies. The predicted strategies indicate that selection strongly favors storage allocation for juveniles, but only for adults when prey densities are high. With the evolution of energy storage, population dynamics can shift from aperiodic to stable cycles without any need to invoke group selection. Copyright 2002 Elsevier Science Ltd.

5361411 AB - Blubber samples from ringed seal (Phoca hispida; n = 8) and polar bear subcutaneous fat (Ursus maritimus; n = 5) were collected near Barrow, Alaska in 1996 as part of the Alaska Marine Mammal Tissue Archival Project (AMMTAP) and retained in the National Biomonitoring Specimen Bank at the National Institute of Standards and Technology in Gaithersburg, Maryland (USA). The samples were analyzed for a variety of persistent organochlorine pollutants (POPs) including polychlorinated biphenyls (PCBs), hexachlorocyclohexanes (HCHs), chlordane and metabolites, hexachlorobenzene (HCB) and DDTs and metabolites. The geometric mean, on a wet mass basis, of capital sigma PCBs (sum of 29 congeners and congener groups) were 732 plus or minus 282 ng/g (1 S.D.) in seals and 3395 plus or minus 1442 ng/g in polar bears. The geometric mean of capital sigma DDTs, capital sigma HCHs ( alpha -, beta - and gamma -HCH) and HCB concentrations (wet mass basis) in seals and bears were 562 plus or minus 261 ng/g vs. 74.8 plus or minus 39 ng/g, 380 plus or minus 213 ng/g vs. 515 ng/g, and 17.4 plus or minus 10.1 ng/g vs. 183 plus or minus 153 ng/g, respectively. The geometric mean sum of chlordane ( capital sigma chlordane, sum of cis- and trans-chlordane, cis- and trans-nonachlor, oxychlordane and heptachlor epoxide) and dieldrin concentrations in ringed seals and polar bears were 753 plus or minus 617 ng/g vs. 720 plus or minus 315 ng/g and 38.6 plus or minus 22.8 ng/g vs. 130 plus or minus 65 ng/g, respectively. Apparent bioaccumulation factors (polar bear/ringed seal POP concentrations) were lower in the animals sampled near Barrow, Alaska than in those from locations in the Canadian Arctic. This suggests that polar bears are also preying on marine mammals from lower trophic levels than the ringed seals with correspondingly lower organochlorine levels, such as bowhead whale carcasses. PCB congener patterns in the samples demonstrated the metabolism of certain PCB congeners in the polar bear relative to the ringed seal in agreement with previous studies. Regional comparisons of animals collected in Alaska and Arctic Canada are presented.

The mean production of natural sand infauna was estimated at between 215 and 249 kcal m super(2) yr super(-1), while that of the epifauna on the reef surfaces was between 3990 and 9555 kcal m super(2) yr super(-1). With the 36 m super(2) footprint of a reef unit as a basis for comparison, the 407 m super(2) of reef unit surface covering that footprint produced 1.62-3.8910 super(6) kcal yr super(-1) of epifauna compared with 7.74-8.9610 super(3) kcal yr super(-1) per footprint area for the adjacent sand infauna. There was, however, substantial annual variability in the productivity of the epifauna, based on the recruitment success of Mytilus edulis.

The reefs were deployed at 40, 50, 70, and 90 m from a flare stack located in a gas field off the coast of Mississippi. Juvenile red snapper were observed at one of the open-bottom sites when it was first surveyed, but none during a second survey conducted 45 days later. Age-0 and age-1 fish showed a preference for the more complex study reefs, but presence of age-1 appeared to limit recruitment of age-0 to a reef. As age-1 fish started to leave the reefs, increased numbers of age-0 were observed moving onto them. However, age-0 were never observed at the 40-m reef occupied by older fish throughout the study. Distance from the flare stack also appeared to have an effect on recruitment to the reefs. Age-0 were first observed at the 50-m reefs. They appeared at the 70-m reefs a week later and at the 90-m reefs almost a month later. Age-1 fish showed a preference for the reefs located closest to the flare stack. Juvenile red snapper site fidelity was determined using fish that either were tagged and released on site or were removed from the capture site before release. Fish from the on-site release were repeatedly sighted at the capture reef over about a 2-month period. Displaced fish, as determined with tracking equipment, were able to find their way back to the capture reef from as far away as 0.43 km in about 25 min. We conclude that juvenile red snapper are not only faithful to structures, but also have homing capabilities.

AN - 918062877; 16140565 AB - US federal agencies must consult with the National Marine Fisheries Service on actions that may adversely affect "essential fish habitat" (EFH). This EFH mandate coincides with recent discussions on proposed decommissioning of oil and gas platforms in southern California. While many species falling under the Pacific Groundfish Fishery Management Plan (e.g. rockfish, genus Sebastes) inhabit platforms, available information is insufficient for determining whether the structures are necessary to support a sustainable fishery or contribute to a healthy ecosystem, the two basic tenets of EFH. The occurrence of juvenile and large adult rockfish at some platforms suggests that they may support important ecological functions. Because rockfish show long-term population declines, further evaluation of platform ecological structure and function is warranted and should be integrated into the environmental review process.

Radiocarbon measurements of BC provide information on the residence time of BC in organic carbon pools like soils and sediments, and also provide information on the source of BC by distinguishing between fossil fuel and biomass combustion byproducts. We have optimized dichromate-sulfuric acid oxidation for the measurement of radiocarbon in BC. We also present comparisons of BC (super 14) C measurements on NIST aerosol SRM 1649a with previously published bulk aromatic (super 14) C measurements and individual polycyclic aromatic hydrocarbon (PAH) (super 14) C measurements on the same NIST standard. Dichromate-sulfuric acid oxidation belongs to the chemical class of BC measurement methods, which rely on the resistance of some forms of BC to strong chemical oxidants. Dilute solutions of dichromate-sulfuric acid degrade BC and marine-derived carbon at characteristic rates from which a simple kinetic formula can be used to calculate concentrations of individual components . We show that: (1) dichromate-sulfuric acid oxidation allows precise, reproducible (super 14) C BC measurements; (2) kinetics calculations give more precise BC yield information when performed on a % OC basis (vs. a % mass basis); (3) kinetically calculated BC concentrations are similar regardless of whether the oxidation is performed at 23 degrees C or 50 degrees C; and (4) this method yields (super 14) C BC results consistent with previously published aromatic (super 14) C data for an NIST standard. For the purposes of intercomparison, we report % mass and carbon results for two commercially available BC standards. We also report comparative data from a new thermal method applied to SRM 1649a, showing that thermal oxidation of this material also follows the simple kinetic sum of exponentials model, although with different time constants.

The previously informally named "Anomaly-T," an east-west trending linear positive magnetic and gravity anomaly lying at about 69 degrees S, forms the southern boundary of the well-known Weddell Sea gravity herringbone. North of Anomaly-T, three major E-W linear magnetic lows are shown, and identified with anomalies c12r, c21-29(r) and c33r. On the basis of these, and following work by recent investigators, isochrons c13, c18, c20, c21, c30, c33 and c34 are identified and extended into the western Weddell Sea. Similarly, a linear magnetic low lying along the spine of the herringbone is shown and provisionally dated at 93-96 Ma. Anomaly-T is tentatively dated to be M5n, in agreement with recent tectonic models. Although current tectonic models are generally in good agreement to the north of T, to the south interpretations differ. Some plate tectonic models have only proposed essentially north-south spreading in the region, whilst others have suggested that a period of predominantly east-west motion (relative to present Antarctic geographic coordinates) occurred during the mid-Mesozoic spreading between East and West Gondwana. We identify an area immediately to the south of T which appears to be the southerly extent of N-S spreading in the herringbone. Following recent work, the extreme southerly extent of the N-S directed spreading of the herringbone is provisionally dated M9r/M10. In the oldest Weddell Sea, immediately to the north and east of the Antarctic shelf, we see subtle features in both the magnetic and gravity data that are consistent with predominantly N-S spreading in the Weddell Sea during the earliest opening of East and West Gondwana. In between, however, in a small region extending approximately from about 50 km south of T to about 70 degrees S and from approximately 40 degrees to 53 degrees W, the magnetic and gravity data appear to suggest well-correlated linear marine magnetic anomalies (possible isochrons) perpendicular to T, bounded and offset by less well-defined steps and linear lows in the gravity (possible fracture zones). These magnetic and gravity data southwest of T suggest that the crust here may record an E-W spreading episode between the two-plate system of East and West Gondwana prior to the initiation of the three-plate spreading system of South America, Africa and Antarctica. The E-W spreading record to the east of about 35 degrees W would then appear to have been cut off at about M10 time during the establishment of N-S three-plate spreading along the South American-Antarctic Ridge and then subducted under the Scotia Ridge.

Seafloor spreading in the northern Natal valley accounts for approximately 170 km of north-south motion between the Mozambique Ridge and Africa. This extension resolves the predicted overlap of the continental (central and southern) Mozambique Ridge and Antarctica in the chron M2 to M11 reconstructions from Mesozoic finite rotation parameters for Africa and Antarctica. In addition, the magnetic data reveal that the Mozambique Ridge was an independent microplate from at least 133 to 125 Ma. The northern Natal valley extinct spreading center connects to the spreading center separating the Mozambique Basin and the Riiser-Larsen Sea to the east. It follows that the northern Mozambique Ridge was either formed after the emplacement of the surrounding oceanic crust or it is the product of a very robust spreading center. To the west the extinct spreading center connects to the spreading center separating the southern Natal valley and Georgia Basin via a transform fault. Prior to chron M11, there is still a problem with the overlap of Mozambique Ridge if it is assumed to be fixed with respect to either the African or Antarctic plates. Some of the overlap can be accounted for by Jurassic deformation of the Mozambique Ridge, Mozambique Basin, and Dronning Maud land. It appears though that the Mozambique Ridge was an independent microplate from the breakup of Gondwana, approximately 160 Ma, until it became part of the African plate, approximately 125 Ma.

Analyses of historical tide data, models, and other research are used to describe the tidal characteristics of a given survey area to generate cotidal charts of co-range and co-phase lines. The number of zones for a particular survey depends upon the complexity of the tide in the area. Each zone is described by a range ratio and a time correction to a water level station in operation during the survey. Tide reducers are compiled by applying the appropriate time and range corrections to the sounding data relative to chart datum which is Mean Lower Low Water (MLLW). Shallow water areas typically have the most complex tidal characteristics where the amplitude of the tide reducers can be a significant percentage of the overall sounding depth and can dominate the overall error budget. In high resolution surveys using multi-beam technology, discrete tidal zoning introduces unwanted jumps when soundings cross from one zone to another. NOS is pursuing research into the application of smooth continuous functions for tide reducers to replace discrete tidal zoning. NOS is developing tools such as Tidal Constituent and Residual Interpolation (TCARI) and Kinematic Global Positioning System (GPS) for operational vertical control. However, these tools still require water level station installations prior to the survey for the development of tidal datum ties to geodetic datum using GPS and to map MLLW relative to the ellipsoid.

A non-invasive, state- of-the-art radiotracer technique was used to study sediment mixing by Heteromastus filiformis (Capitellidae), a common marine head-down deposit feeder, exposed to several sublethal concentrations of DDT (0, 5, 10 and 20 mu g/g; control, Treatments 1, 2 and 3). Several horizontal submillimeter layers of super(137)Cs-labeled clay were deposited approximately every 2 cm in each of 3 replicate sediment columns per treatment; 4 polychaetes were then introduced to each column and the gamma activity of each column was measured vertically using an automated scan detector. Nonlinear leastsquare fits were applied to obtain parameterized values that were used to determine the mixing rates of each super(137)Cs layer over time. A simple diffusion model was used to calculate biological diffusion coefficients (D sub(b)) for H. filiformis. Overall mixing rates increased towards the surface. Control and Treatment 1 had higher D sub(b) values at the surface compared to Treatments 2 and 3. The D sub(b) depth profiles were similar in the control and Treatments 1 and 2, with mixing occurring at the sediment water interface and a subsurface maximum at 10 to 12 cm below this interface. This pattern was not clear in Treatment 3, where D sub(b) had the lowest values and decreased with depth. Bioturbation besides mixing of solids also changed the water content throughout the sediment column. Porosity profiles at the end of the experiments increased by 10 to 20% at 10 to 12 cm depths compared to above and below this horizon. The DDT depth concentration profiles decreased towards the surface as a result of the mixing by the benthic macroinvertebrates, clearly indicating removal/uptake by the organism. The feeding rate constant ( gamma sub(b) %/h) in the control showed a maximum at 7 to 12 cm. However, the gamma sub(b) in the treatments was essentially constant with depth. For all treatments and the control, the burial rate (W sub(b)) (downward movement of radiolabeled layers) decreased with depth. The surface layers were buried faster (ANOVA, p < 0.05) in the control than in sediments containing DDT. A sensitivity analysis comparing burial rate, D sub(b), gamma sub(b) (surface only) and worm weights showed that worm weights and burial rate have the highest fractional rate changes per mu g/g DDT.

El Nino Southern Oscillation (ENSO) scale variability of 2 to 7 yr periods is dominant in the eastern Equatorial Pacific and decadal scale variability of 10 to 30 yr periods is dominant in the northeastern Pacific. In the eastern Pacific warm pool at the center of the ETP, temporal variability at any scale is relatively low. ENSO warm (El Nino) and cold (La Nina) events have had a variety of effects on marine populations and ecosystems, but these effects are generally followed by recovery within a few years. El Nino effects such as mortality or reproductive failure are most severe on populations dependent on local feeding or breeding grounds in coastal waters or around islands. Decadal variability has also caused change in populations and ecosystems. Most of these effects have been observed in the California Current, Gulf of Alaska, and other well studied regions of the Pacific. The 1976-1977 phase change or 'regime shift' is the most well known case of decadal variability. It affected the physical environment throughout the Pacific Ocean and had major effects on North Pacific ecosystems. No regime shift has been detected in the ETP since 1977. However, ENSO variability continues, an unusually persistent warming prevailed in the early 1990s and the thermocline has shoaled in the ETP warm pool area since 1980. Potential population effects on dolphin stocks are discussed. Interaction of environmental changes with other factors, such as fishery stress or mortality, may also induce population effects.

Recent research has indicated that more than one cholinesterase may be present in tissues of estuarine organisms and that these cholinesterases vary in their sensitivity to organophosphorus insecticides. Baseline cholinesterase activity for adult grass shrimp (Palaemonetes pugio) was determined with four substrates (acetylthiocholine iodide, acetyl- beta -methylthiocholine iodide, propionylthiocholine iodide, S-butyrylthiocholine iodide) and three cholinesterase inhibitors (eserine sulfate, tetraisopropyl pyrophosphoramide, 1,5-bis(4-allyldimethyl-ammoniumphenyl) pentan-3-one dibromide). Cholinesterase activity was the highest with acetylthiocholine iodide at 57.42 nmol/mg P/min and the lowest with acetyl- beta -methylthiocholine iodide at 6.17 nmol/mg P/min. The four substrates tested were not inhibited by tetraisopropyl pyrophosphoramide. Eserine sulfate significantly inhibited cholinesterase activity against all substrates exceptS -butyrylthiocholine iodide.

We found that there have been marked changes in the island avifauna with two main trends evident. First, a volcanic eruption destroyed much of the island in 1952. The Wedge-tailed Shearwater (Puffinus pacificus; estimated breeding population 1,000 pairs), Townsend's Shearwater (Puffinus auricularis; probable breeder, small numbers), and Red-footed Booby (Sula sula; 60 pairs) historically had much larger populations, but they apparently never fully recovered from the eruption. The Masked Booby (Sula dactylatra; 2,185 pairs), however, has become much more abundant perhaps due to changes in the vegetation. The second trend is that within the last three decades at least two, and possibly four, species from the central Pacific have colonized the island. The Laysan Albatross (Phoebastria immutabilis; 12 pairs) started breeding in the late 1980s; Black-footed Albatross (Phoebastria nigripes; 1 pair) in 2000. Red-tailed Tropicbirds (Phaethon rubricauda; probable breeder, 10 pairs) may have started breeding in the 1980s, and at least some of the breeding Brown Boobies (Sula leucogaster; 300 pairs) are from central Pacific populations. The reason(s) for this influx of central Pacific species is unknown, but likely involves changes in the marine environment. Other breeding species include the Red-billed Tropicbird (Phaethon aethereus; 200 pairs), Nazca Booby (Sula granti; 50 pairs), Great Frigatebird (Fregata minor; 165 pairs), and Magnificent Frigatebird (Fregata magnificens; 5 pairs).

A liquid waveguide capillary flow cell has been used to extend the sensitivity of a conventional autoanalyzer for the automated analysis of nanomolar concentrations of phosphate in natural waters. Total reflection of light can be achieved within the liquid core of the flow cell because the refractive index of a cell wall coated with Teflon 1600 is lower than that of water. This property allows the manufacturers to construct long liquid waveguide capillary flow cells in a helical, rather than a linear shape, with compact dimensions. A small sample volume is required because the internal volume of a 2-m long capillary flow cell is only approximately 0.5 cm super(3). Adaptation of this long flow cell to autoanalyzers significantly enhances the sensitivity of automated colorimetric analysis of phosphate with a molybdenum blue method, allowing for the accurate and precise determination of nanomolar concentrations of phosphate in natural waters. The advantages of this technique are a low detection limit (0.5 nM), a small sample volume (2 mL), high precision (2% at 10 nM levels), and automation for the rapid analysis of a large number of samples.

Although proteins are the focus of most current drug discovery efforts, exciting new research has recently begun which aims to exploit ribonucleic acid (RNA) and RNP particles as novel targets for pharmaceutical development. These RNA-targeted research efforts have been fueled by an increased appreciation for the central role played by RNA and RNA-protein interactions in many biological processes and diseases, together with a better understanding of RNA structure and an improvement in biophysical/biochemical techniques available to study RNA. As for protein targets, genome sequencing is greatly accelerating the identification of human and microbial RNA transcripts for targeted drug discovery. With this explosion in the number of potential RNA and RNP targets, the effective development of specific small molecule RNA-based drugs requires robust and general approaches for detecting and quantifying RNA-ligand interactions, which can be used as high-throughput screens (HTS) and for obtaining rapid structural information to guide rational drug design. In this review, an overview of the potential for therapeutic intervention based on RNA and RNP targets is presented, together with recent efforts to develop generally useful nuclear magnetic resonance (NMR) and fluorescence binding assays for screening and optimizing drugs aimed at RNA and RNP targets.

The Coastal Storms Initiative (CSI) AN - 18564224; 5368900 AB - Currently, more than half of the population of the United States lives in the coastal zone. It is important to ensure the safety of this population, help the coastal economy, and sustain the natural environment. Unfortunately, storms in coastal areas are more severe and are less predictable than in the interior of the country. In particular, forecasts of storms and associated precipitation patterns in coastal areas lag behind those for the rest of the nation, owing to observational deficiencies over adjacent oceans, a poor understanding of the physical and chemical processes near the air-ocean-land interface, and associated deficient modeling systems. Coastal storm losses have an economic as well an environmental impact with damages estimated at between ten billion and fifty billion dollars each year. In fact, the cost per single storm event averages a half billion dollars (Heinz Center, 2000). Scientific and management expertise now exists, both within and outside government, that can help ensure the safety of the coastal population, help the coastal economy, and sustain the coastal environment.

On the U.S. West Coast, periods of favorable and adverse conditions may last 30 yrs each. A constant-harvest-rate policy may work for long-lived fishes (those with life spans comparable to or exceeding the duration of adverse conditions). Exploitation of short-lived fishes (species with life spans shorter than the duration of adverse conditions) benefits from policies that link harvest rate to environmental conditions, but a delayed response can be desirable. Therefore, rapid identification of regime shifts is not necessary but could provide advance notice of long-term changes in expected harvests. Planning horizons, especially for stock rebuilding, may have to be much longer than has been typical, even a century or more. During adverse periods little rebuilding may occur even after total cessation of fishing. Adverse species interactions like intraguild competition or `cultivation effects' may prolong rebuilding or reduce sustainable yields. Management reference points like F sub(msy) and B sub(msy) can be strongly influenced by abundance of competitors. Importantly, B sub(msy) of large predators may be well above half the unfished biomass if their removal releases smaller competitors. Although adverse interactions may be reversible, rebuilding of apex predators may require decades to centuries.

It is a member of a ubiquitous group of benthic cnidarians called sea pens (Octocorallia: Pennatulacea). Sea pens have a skeletal structure, the axial rod, that in cross section exhibits growth rings. Pairs of adjacent rings, or ring couplets, were assumed to be annuli and were used to estimate the age and growth of H. willemoesi. Twelve axial rods, extracted from H. willemoesi collected in the Bering Sea, were selected to represent small (25-29 cm total length), medium (97-130 cm TL) and large (152-167 cm TL) colonies. Each rod resembled a tapered dowel; the thickest part (0.90-6.75 mm in diameter) was at about 5-10% of total length from the base tip, the distal part was more gradually tapered than was the base. The number of ring couplets increased with rod size indicating their utility in estimating age and growth. Estimated age among rods was based on couplet counts at the thickest part of each rod; the average estimated age ( plus or minus SE) was 7.1 plus or minus 0.7, 19.3 plus or minus 0.5, and 44.3 plus or minus 2.0 yr for small, medium and large-size rods, respectively. Based on these estimated ages, average growth rate in total length was 3.9 plus or minus 0.2, 6.1 plus or minus 0.3, and 3.6 plus or minus 0.1 cm yr super(-1) for small, medium, and large-size colonies. The average annual increase in maximum rod diameter among all colonies was 0.145 plus or minus 0.003 SE mm yr super(-1); therefore, age prediction from maximum rod diameter was calculated (estimated age (yr) = 7.0 * (maximum rod diameter, mm) -0.2; R super(2) = 0.99). At maximum diameter, the average couplet width was relatively constant among the three colony sizes (0.072 plus or minus 0.05 mm). X-ray diffraction and electron microprobe analyses revealed that the inorganic portion of the rod is composed of a high-magnesium calcite. Radiometric validation of these age and growth rate estimates was attempted, but high amounts of exogenous super(210)Pb precluded using the disequilibria of super(210)Pb: super(226)Ra. Instead, super(210)Pb activities were measured in a series of cores extracted along the axial rod. These activities ranged from 0.691 plus or minus 0.036 (SE) to 2.76 plus or minus 0.13 dpm g super(-1), but there was no pattern of decay along the length of the rod; therefore, the growth rates and corresponding ages could not be validated. Based on estimated age from ring couplet counts, growth in total rod length is slow at first, fastest at medium size, and slows toward maximum size, with an estimated longevity approaching 50 yr.

In each trial, final erythromycin concentration in Artemia tissue and survival after a 12-h bioencapsulation period were determined.

The proportion of DON utilized ranged from 0 to 73%. Overall, urban/suburban storm water runoff had a higher proportion of bioavailable DON (59% plus or minus 11) compared to agricultural pastures (30% plus or minus 14) and forests (23% plus or minus 19). DON bioavailability varied seasonally; however, the seasonal pattern differed for the three sources. Bacterial production increased linearly with the amount of DON utilized across all sources and seasons; the rate of increase was approximately five times greater per micromole of N as DON used relative to dissolved inorganic N (DIN) used. Although phytoplankton production generally increased with DON addition, the increased production was not correlated with the amount of DON utilized, suggesting that a variable portion of dissolved organic matter (DOM)-N was directly or indirectly available to the phytoplankton. This indicates that phytoplankton production is not a good measure of the amount of bioavailable DON, and measurements of the amount of bioavailable DON based on bacterial responses alone might not reflect N available to phytoplankton. Preliminary seasonal budgets of bioavailable N (DIN plus bioavailable DON) as a function of land use suggest that similar to 80% of the total dissolved N (TDN) from urban/suburban runoff is bioavailable, whereas a lower proportion (20-60%) of TDN is bioavailable from forests and pastures. N budgets for aquatic ecosystems based on only DIN loading underestimate bioavailable N loading, whereas total N or TDN budgets overestimate bioavailable N inputs.

Quantitative genetic studies are typically expensive and time-consuming to conduct, especially in some of the long-lived vertebrates of conservation concern. The present review of recent literature in fish conservation genetics examines the traditional role of molecular studies in describing conservation units and providing indirect inference about local adaptation and adaptive potential. Of special interest are approaches that use a combination of molecular and quantitative genetic methods. Such studies are likely to provide important new insights into many conservation-related problems. The review also explores how increasing interest in non-neutral molecular markers is contributing to our understanding of the geographic scale and evolutionary importance of local adaptation in threatened populations. It is increasingly clear that advanced genetic technologies for the exploration of neutral and non-neutral molecular variation are leading to a fundamental shift in the way complex phenotypic traits are studied. This new synthesis of methods will have dramatic implications for fish conservation genetics and biology in general.

There has been a noticeable shift in the abundance of these predators during the last four decades, which is generally attributed to fishing pressure. Although many fish persist as piscivores in this system, not only has their relative abundance changed but their size composition has also changed. Both factors influence the total magnitude of piscivory by these fish. To ascertain the cascading effects of fishing on fish predation, we examined relative abundance, total stomach contents, diet composition, consumption rates, and total food consumption of fish for several species across the time period. The proportion of the diet comprised by fish for piscivores on Georges Bank has remained remarkably consistent. However, the composition of specific fish prey has changed across the time series. Total fish consumption generally tracked predator abundance, but two species demonstrated compensating consumption rates as larger size classes declined. Contrary to our initial hypothesis, total fish consumption by six major predators has remained generally constant despite changes in predator size, structure and abundance. One reason for constant systemic piscivory is the dominant piscivore in this ecosystem has shifted from cod to spiny dogfish. We assert that a major effect of intense fishing pressure is a shift in energy flow for marine ecosystems.

The function of the protein had not been assigned previously, and it is annotated as hypothetical in sequence databases. The protein exhibits the alpha / beta -hydrolase fold (also termed the Rossmann fold) and resembles most closely the fold of the L-2-haloacid dehalogenase (HAD) superfamily. Following this observation, a detailed sequence analysis revealed remote homology to two members of the HAD superfamily, the P-domain of Ca super(2+) ATPase and phosphoserine phosphatase. The 19-kDa chains of HI1679 form a tetramer both in solution and in the crystalline form. The four monomers are arranged in a ring such that four beta -hairpin loops, each inserted after the first beta -strand of the core alpha / beta -fold, form an eight-stranded barrel at the center of the assembly. Four active sites are located at the subunit interfaces. Each active site is occupied by a cobalt ion, a metal used for crystallization. The cobalt is octahedrally coordinated to two aspartate side-chains, a backbone oxygen, and three solvent molecules, indicating that the physiological metal may be magnesium. HI1679 hydrolyzes a number of phosphates, including 6-phosphogluconate and phosphotyrosine, suggesting that it functions as a phosphatase in vivo. The physiological substrate is yet to be identified; however the location of the gene on the yrb operon suggests involvement in sugar metabolism.

Part I: Single-Doppler Velocity Retrieval AN - 18296637; 5335542 AB - In this two-part study, a single-Doppler parameter retrieval technique is developed and applied to a real-data case to provide initial conditions for a short-range prediction of a supercell thunderstorm. The technique consists of the sequential application of a single-Doppler velocity retrieval (SDVR), followed by a variational velocity adjustment, a thermodynamic retrieval, and a moisture specification step. By utilizing a sequence of retrievals in this manner, some of the difficulties associated with full-model adjoints (possible solution nonuniqueness and large computational expense) can be circumvented. In Part I, the SDVR procedure and present results from its application to a deep-convective storm are discussed. Part II focuses on the thermodynamic retrieval and subsequent numerical prediction. For the SDVR, Shapiro's reflectivity conservation-based method is adapted by applying it in a moving reference frame. Verification of the retrieved wind fields against corresponding dual-Doppler analyses indicates that the best skill scores are obtained for a reference frame moving with the mean wind, which effectively reduces the problem to a perturbation retrieval. A decomposition of the retrieved wind field into mean and perturbation components shows that the mean wind accounts for a substantial portion of the total retrieved azimuthal velocity. At low levels, where the retrieval skill scores are especially good, the retrieved perturbation azimuthal velocity is mostly associated with the polar component of vorticity. Missing from the retrieved fields (compared to the dual-Doppler analysis) is most of the low-level azimuthal convergence. Consistent with this result, most of the retrieved updraft is associated with convergence of the perturbation radial velocity, which is calculated from the observed radial velocity and directly used in the wind retrieval.

Part II: Thermodynamic Retrieval and Numerical Prediction AN - 18294681; 5335543 AB - In this two-part study, a single-Doppler parameter retrieval technique is developed and applied to a real-data case to provide model initial conditions for a short-range prediction of a supercell thunderstorm. The technique consists of the sequential application of a single-Doppler velocity retrieval (SDVR), followed by a variational velocity adjustment, a thermodynamic retrieval, and a moisture specification step. In Part I, the SDVR procedure is described and results from its application to a supercell thunderstorm are presented. In Part II, results from the thermodynamic retrieval and the numerical model prediction for this same case are presented. For comparison, results from parallel sets of experiments using dual-Doppler-derived winds and winds obtained from the simplified velocity retrieval described in Part I are also shown. Following the SDVR, the retrieved wind fields (available only within the storm volume) are blended with a base-state background field obtained from a proximity sounding. The blended fields are then variationally adjusted to preserve anelastic mass conservation and the observed radial velocity. A Gal-Chen type thermodynamic retrieval procedure is then applied to the adjusted wind fields. For all experiments (full retrieval, simplified retrieval, and dual Doppler), the resultant perturbation pressure and potential temperature fields agree qualitatively with expectations for a deep-convective storm. An analysis of the magnitude of the various terms in the vertical momentum equation for both the full retrieval and dual-Doppler experiments indicates a reasonable agreement with predictions from linear theory. In addition, the perturbation pressure and vorticity fields for both the full retrieval and dual-Doppler experiments are in reasonable agreement with linear theory predictions for deep convection in sheared flow. Following a simple moisture specification step, short-range numerical predictions are initiated for both retrieval experiments and the dual-Doppler experiment. In the full single-Doppler retrieval and dual-Doppler cases, the general storm evolution and deviant storm motion are reasonably well predicted for a period of about 35 minutes. In contrast, the storm initialized using the simplified wind retrieval decays too rapidly, indicating that the additional information obtained by the full wind retrieval (primarily low-level polar vorticity) is vital to the success of the numerical prediction. Sensitivity experiments using the initial fields from the full retrieval indicate that the predicted storm evolution is strongly dependent on the initial moisture fields. Overall, the numerical prediction results suggest at least some degree of short-term predictability for this storm and provide an impetus for continued development of single-Doppler retrieval procedures.

The flames were assumed to be soot-dominated with blackbody emission characteristics. The ambient surroundings near the flames were assumed to be homogeneous with the total pressure being fixed at one atmosphere. Atmospheric CO sub(2) concentrations were held constant at 0.04 kPa and the water vapor concentrations varied between 0.55-5.63 kPa based on temperature and relative humidity. The remaining partial pressures were accounted for by O sub(2) and N sub(2). Correlations to estimate atmospheric attenuation are given over a range of conditions that include path length (10-200 m), ambient temperature (19-35 degree C), source temperature (1000-1600 degree C) and relative humidity (0.25-1.0) as parameters. The results of these calculations indicate that, over this range of conditions, the radiant flux can be attenuated by as much as 42%.

Ironically, most published studies of artificial reefs are observational despite the fact that their manipulative nature lends these reefs to an experimental approach, and despite the potential benefits of an experimental, process-oriented approach to fulfilling their objectives. Most applications of artificial reefs are underpinned by ecological processes ranging from trophic interactions and recruitment to individual physiology and biogeochemical cycling. Examples concerning three goals are discussed; enhancement of fisheries production, ecosystem restoration, and water quality enhancement. These examples illustrate (1) predictions that can be drawn from basic ecological studies of 'natural' reef organisms and ecosystems regarding ecological structure, processes, and performance of artificial reefs, and (2) how an experimental ecological approach has been (or could be) utilized to elucidate ecological process and yield specific improvements in the application of artificial reefs to achieve management goals. In fact, answering the 'why' and 'how' questions addressed by experimental process studies is the only way to improve our success in achieving any sort of ecological engineering objectives.

A statistical model of the fluxes from each atmospheric product is coupled to an ocean general circulation model (GCM). Four different products are evaluated: reanalyses from the National Centers for Environmental Prediction (NCEP) and the European Centre for Medium-Range Weather Forecasts (ECMWF), satellite-derived data from the Special Sensor Microwave/Imaging (SSM/I) platform and the International Satellite Cloud Climatology Project (ISCCP), and an atmospheric GCM developed at the Geophysical Fluid Dynamics Laboratory (GFDL) as part of the Atmospheric Model Intercomparison Project (AMIP) II. For this study, comparisons between the datasets are restricted to the dominant air-sea mode. The stability of a coupled model using only the dominant mode and the associated predictive skill of the model are strongly dependent on which atmospheric product is used. The model is unstable and oscillatory for the ECMWF product, damped and oscillatory for the NCEP and GFDL products, and unstable (nonoscillatory) for the satellite product. The ocean model is coupled with patterns of wind stress as well as heat fluxes. This distinguishes the present approach from the existing paradigm for ENSO models where surface heat fluxes are parameterized as a local damping term in the sea surface temperature (SST) equation.

Although the traps themselves are inexpensive, the deployment and retrieval of them is costly, which restricts both the quantity and frequency of samples. To overcome this, a programmable sequencing sediment trap was designed and tested for use in large lakes and coastal systems. Sediment is collected into a carousel of 23 standard 60 ml (Nalgene super(TM)) polyethylene sample bottles. The sequencing design incorporates an electric motor and paddle to rotate the carousel so that one sample bottle at a time is exposed according to a preprogrammed schedule. These traps incorporate a cylindrical design with a 20 cm collection opening and an 8:1 aspect ratio. The micro-controller monitors the operation and records operational parameters allowing confirmation of the exposure time of each bottle. Several field tests were conducted to verify the precision and uniformity of the sediment collection. Improvements made over the 10 years of deployment experience and field testing have resulted in a very reliable and low-cost instrument.

We also examined the species of commercially managed fish that are associated with coral. Soft corals, primarily Gersemia sp. (=Eunephthya sp.), were the most frequently encountered corals in the Bering Sea. In the Aleutian Islands gorgonian corals, primarily in the genera Callogorgia, Primnoa, Paragorgia, Thouarella, and Arthrogorgia were the most common corals. In the Gulf of Alaska, gorgonian corals, primarily in the genera Callogorgia and Primnoa, and cup corals, primarily `Scleractinia unidentified', occurred most frequently. The Aleutian Islands area appears to have the highest abundance and diversity of corals. Some fish groups are associated with particular types of coral. Rockfish (Sebastes spp. and Sebastolobus alascanus) and Atka mackerel (Pleurogrammus monopterygius) were the most common fish captured with gorgonian, cup, and hydrocorals, whereas flatfish and gadids were the most common fish captured with soft corals.

Deepwater corals (Primnoa spp.) were observed from a manned submersible at 11 sites in the Gulf of Alaska from 1989 to 1997 at depths of 161-365 m. We identified 10 megafaunal groups that associate with Primnoa to feed on the coral, use the coral branches for suspension feeding, or for protection. Predators on Primnoa polyps included sea stars, nudibranchs, and snails. Sea stars were the main predators, consuming 45% and 34% of the polyps at two sites. Suspension-feeders included crinoids, basket stars, anemones, and sponges. Most suspension-feeders observed at depths >300 m were associated with Primnoa. Protection seekers included rockfish, crab, and shrimp. Six rockfish species were either beneath, among, or above Primnoa. Shrimp were among the polyps, and a pair of mating king crabs were beneath Primnoa. These observations indicate Primnoa are important components of the deepwater ecosystem and removal of these slow-growing corals could cause long-term changes in associated megafauna.

Enclosures (n = 60; 3 fish per enclosure) were deployed throughout the Navesink River/Sandy Hook Bay estuarine system, New Jersey, in a nested spatial design that allowed measurement of growth variation in time at 3 spatial scales (between regions: infinity -distance [D] = 12.3 km, SD = 3.6, n = 2; between sectors: infinity -D = 4.3 km, SD = 1.3, n = 6; between stations: infinity -D = 1.8 km, SD = 0.8, n = 12). Three 12 d enclosure experiments were performed over 40 consecutive days from mid-May through June 1999. Flounder growth (range = 0 to 0.9 mm SL/d/enclosure) was dynamic at a regional spatial scale. Generalized additive modeling indicated that growth was most rapid at relatively cool temperatures (< 21 degree C) and low salinities (< 24[per thou]). However, spatial analysis of partial growth indicated that the relative influences of temperature and salinity changed over time. Salinity effects were strongest during the earliest experiment (May 20 to June 1) when temperatures were cool (< 20 degree C) throughout the estuary. During this period, salinities were conducive for rapid growth throughout the river. From June 4 to 16, salinities remained optimal in the river, but as the system warmed, temperatures conducive for rapid growth contracted into the bay and temperature effects became stronger than salinity effects. Growth was more rapid in the bay, but not as high as that measured during the first experiment in the river where optimal salinities and temperatures overlapped within the estuary. With continued warming and curtailed freshwater runoff, temperatures were sub-optimal throughout the estuary, salinities were conducive for rapid growth only in the upper river, and from June 18 to 30 growth rates were relatively low. Our analysis suggests that habitat suitability for the growth of juvenile fish can be spatially dynamic because multiple regulatory factors vary simultaneously in space and time. Rapid growth occurs at sites and times when optimal conditions for regulatory factors intersect in space, but the spatial coincidence of optimal conditions can be ephemeral.

The sediment data have been used to define the status or geographic distribution of chemical concentrations (Daskalakis, K. D., & O'Connor, T. P (1995). Distribution of chemical contamination in coastal and estuarine sediments. Marine Environmental Research 40, 381-398) and the molluscan data have provided an estimate of temporal trends (O'Connor, T. P. (1996). Trends in chemical concentrations in mussels and oysters collected along the US coast from 1986 to 1993. Marine Environmental Research 41, 183-200, O'Connor, T. P. (1998). Mussel Watch results from 1986 to 1996. Marine Pollution Bulletin 37, 14-19). This paper centers on chemical concentrations in mollusks at 263 sites around the United States. It provides perspective on concentration ranges and on geographic distributions. For most organic chemicals and lead, concentrations vary in proportion to numbers of people living near a site. For elements, other than lead, high concentrations in mollusks can be due more to natural factors than to human activity. Concentrations of PAHs in tissues of mussels from urban areas are in a range reported to exert biological responses.

Discrimination among clouds of differing ice particle types is also important because both the presence and type of ice influence the survival of liquid in a cloud and the chances for occurrence of these large, most hazardous droplets. This work shows how millimeter-wavelength dual-polarization radar can be used to identify these differing hydrometeors. It also shows that by measuring the depolarization ratio (DR), the estimation of the hydrometeor type can be accomplished deterministically for drizzle droplets; ice particles of regular shapes; and to a considerable extent, the more irregular ice particles, and that discrimination is strongly influenced by the polarization state of the transmitted microwave radiation. Thus, appropriate selection of the polarization state is emphasized. The selection of an optimal polarization state involves trade-offs in competing factors such as the functional dynamic range of DR, sensitivity to low-reflectivity clouds, and insensitivity to oscillations in the settling orientations of ice crystals. A 45 degree slant, quasi-linear polarization state, one in which only slight ellipticity is introduced, was found to offer a very good compromise, providing considerable advantages over standard horizontal and substantially elliptical polarizations. This was determined by theoretical scattering calculations that were verified experimentally in field measurements conducted during the Mount Washington Icing Sensors Project (MWISP). A selectable-dual-polarization K sub(a)-band (8.66-mm wavelength) radar was used. A wide variety of hydrometeor types was sampled. Clear differentiation among planar crystals, columnar crystals, and drizzle droplets was achieved. Also, differentiation among crystals of fundamentally different shapes (aspect ratios) within each of the planar and columnar families was found possible. These distinctions matched calculations of DR, usually to within 1 or 2 dB. The results from MWISP and from previous experiments with other polarizations have demonstrated that the agreement between theory and measurements by this method is repeatable. Additionally, although less rigorously predicted by theory, the field measurements demonstrated substantial differentiation among the more irregular and more spherical ice particles, including aggregates, elongated aggregates, heavily rimed dendrites, and graupel. Measurable separation between these various irregular ice particle types and drizzle droplets was also verified.

The number of worms increased between the beginning and end of the experiment at 59 mu g g super(m1) fluoranthene, but at the next higher treatment (108 mu g g super(m1)) the number of worms found was lower and not different from the control. Worms exposed to 95 mu g g super(m1) also exhibited increased reproduction when fed a yeast-cerophyl-trout chow mixture. On a total biomass basis, only the 95 mu g g super(m1) exposure with food exhibited a statistically significant increase over the nonfed control. Evaluation of reproduction at the two highest treatments was compromised by a brief aeration failure 2 days before the end of the experiment. The behavioral responses were followed as changes in biological burial rate (sediment reworking rate) of a super(137)Cs-labeled marker layer. The biological burial rate increased toward a plateau as the concentration increased from the control (3.9 mu g g super(m1) dry weight total PAH) to 355 mu g g super(m1) dry weight fluoranthene in sediment. The aeration failure had minimal impact on the determination of reworking rate because all the data for the rate determination were collected prior to the aeration failure. Uptake and elimination rates declined with increasing treatment concentration across the range of fluoranthene concentrations, 59-355 mu g g super(m1) dry weight sediment. The disconnect between the increasing biological burial rates and the decreasing toxicokinetics rates with increasing exposure concentration demonstrates that the toxicokinetic processes are dominated by uptake and elimination to interstitial water. The bioaccumulation factor (concentration in the organisms on a wet weight basis divided by the concentration in sediment on a dry weight basis) ranged from 0.92 to 1.88 on day 10 and declined to a range of 0.52 to 0.99 on day 28 with the lowest value at the highest dose.

Reversing the burden of proof (showing that a given fishing level is safe before allowing it) is a necessary but not sufficient condition for a precautionary approach. Several policy aspects of the burden of proof issue should be clarified: what the default decision will be; who bears the burden of demonstrating that a change from the default is justified; what metric is used to decide on a change; and what rate of incorrect changes from the default is tolerable. Fishery decision making would benefit from more specificity about management goals, preagreement on how data will be used in reaching decisions, and an explicit linking of fishing levels to the degree of certainty of fish stock condition. Finally, we argue that a truly precautionary approach requires a broader philosophical outlook than seeing the oceans as simply providing exploitable resources. Management should aim to maintain all marine species as functioning components of their ecosystems and to permit a proposed activity only if it can be demonstrated not to have an adverse effect.

AN - 16140847; 5459375 AB - Ecosystem-based fishery management (EBFM) is a holistic approach to maintaining ecosystem quality and sustaining associated benefits. Sustaining the diverse products and services expected from marine ecosystems requires a broad interdisciplinary approach. Here, we propose a three-step approach to implementation of EBFM that consists of goals, metrics, and management. Setting policy goals is an important first step in the fishery-management process. Goals must be translated into clear quantifiable terms, i.e., metrics. Metrics, alternatively referred to as performance measures or reference points, are used to indicate the status of system attributes. Multiple metrics will generally be needed to account for diverse, and possibly conflicting, societal goals. Biotic metrics range from single-species to whole-system attributes. Abiotic metrics describe environmental conditions. Human metrics describe human activities and are essential for managing human impacts. These metrics can serve as the basis for decision criteria and reference points for the management process. We illustrate our approach to EBFM using the groundfish trawl fishery system in the Georges Bank region of the Northwest Atlantic.

Of the 22 shark species found, the silky shark was the most dominant (31.4% of the total catch). Catch status (alive or dead) on gear retrieval varied widely depending on the species, with high mortalities occurring in the silky and night sharks and low mortalities for rays, blue, and tiger sharks. Other data on discard percentages, mean fork lengths (a measure of maturity), and sex ratios are summarized. Yearly mean catch rates were estimated, showing some variability for most species but some significant trends for night, oceanic whitetip, and sandbar sharks. The utility of these findings for better management of pelagic sharks and preventing overfishing is discussed.

The history of quahog harvesting in specific Canadian provinces and U.S. and Mexican states is summarized, based on author observations and literature reports. The U.S. is the leading producer of quahogs. Harvest equipment has evolved considerably over the last 200 yr. Modern dredges have hydraulic jets. Regulations to conserve and maximize quahog yields were first developed in the early 1900s. Such regulations now include a nearly universal size limit of a 38 mm shell width, and may include gear limitations and daily quotas. In some areas, quahog enhancement programs have been established. Most involve transplanting stocks from uncertified waters to certified beds, and planting seed grown in hatcheries. Other issues examined include the socioeconomics of quahog fisheries, relations between quahoging and other fisheries (and aquaculture development), community perspectives on the quahog industry, and quahog management programs.

Given funding limits, the selection of appropriate sites must weigh ecological benefits as well as public and political support. Regional or watershed goals have recently been used to prioritize potential restoration sites. The inclusion of social goals as well as these ecological goals is the subject of a decision support tool in development. This tool is used in conjunction with GIS data to make a "first cut". It is based on expert assessment of wetland functions, assessment of the public values for wetland attributes, and geographic information system maps that identify and prioritize potential sites based on user inputs.

AN - 36416062; 9190 AB - PURPOSE: The implementation of Amendment 13 to the summer flounder, scup, and black sea bass fishery management plan (FMP) is proposed. The management units for the FMP, which remain unchanged by the amendment, are, for summer flounder, the US waters in the western Atlantic Ocean from the southern border of North Carolina northward to the US/Canada border and, for scup and black sea bass, the US waters in the western Atlantic Ocean from Cape Hatteras, North Carolina northward to the US/Canadian border. The amendment would revise the quarterly commercial quota system for black sea bass implemented in Amendment 9 to the FMP; address the problem related to permit requirements for fishermen that have both a northeast black sea bass a southeast snapper/grouper permit and fish for black sea bass north and south of Cape Hatteras, North Carolina; address problems related to the wet storage of black bass pots and traps; establish de minimus specifications for black sea bass under the Atlantic State Marine Fisheries Commission Interstate Fisheries Management Program Charter; implement tag requirements for black sea bass pots and traps; limit the number of black sea bass pots and traps fished by fisherman to 800,; and assess the impacts of fishing activities on essential fish habitat (EFH) and implement management alternatives for summer flounder, scup, and black bass to prevent, mitigate, or minimize adverse impacts from fishing to bring the FMP into compliance with the Sustainable Fisheries Act. Several alternatives are outlined for each species. POSITIVE IMPACTS: The amended FMP would reduce fishing mortality affecting the target species to assure overfishing does not occur, reduce fishing mortality affecting stocks of immature individuals of the species, improve yield from the affected fisheries, promote compatibility across federal and state regulatory regimes and uniform enforcement of regulations, and minimize regulatory constraints to achieve the foregoing management objectives., NEGATIVE IMPACTS: Certain regulatory restrictions resulting in reduced catch for some areas and fishing interests could cause localized economic hardships.

In the first step, a glutamine amidotransferase encoded by the pabA gene generates ammonia as a substrate that, along with chorismate, is used in the second step, catalyzed by aminodeoxychorismate synthase, the product of the pabB gene. Here we report the X-ray crystal structure of Escherichia coli PabB determined in two different crystal forms, each at 2.0 AA resolution. The 453-residue monomeric PabB has a complex alpha / beta fold which is similar to that seen in the structures of homologous, oligomeric TrpE subunits of several anthranilate synthases of microbial origin. A comparison of the structures of these two classes of chorismate-utilizing enzymes provides a rationale for the differences in quaternary structures seen for these enzymes, and indicates that the weak or transient association of PabB with PabA during catalysis stems at least partly from a limited interface for protein interactions. Additional analyses of the structures enabled the tentative identification of the active site of PabB, which contains a number of residues implicated from previous biochemical and genetic studies to be essential for activity. Differences in the structures determined from phosphate- and formate-grown crystals, and the location of an adventitious formate ion, suggest that conformational changes in loop regions adjacent to the active site may be needed for catalysis. A surprising finding in the structure of PabB was the presence of a tryptophan molecule deeply embedded in a binding pocket that is analogous to the regulatory site in the TrpE subunits of the anthranilate synthases. The strongly bound ligand, which cannot be dissociated without denaturation of PabB, may play a structural role in the enzyme since there is no effect of tryptophan on the enzymic synthesis of aminodeoxychorismate. Extensive sequence similarity in the tryptophan-binding pocket among several other chorismate-utilizing enzymes, including isochorismate synthase, suggests that they too may bind tryptophan for structural integrity, and corroborates early ideas on the evolution of this interesting.

This study, using the National Oceanic and Atmospheric Administration Geophysical Fluid Dynamics Laboratory hurricane model, examines the surface temperature changes due to hurricane-land surface water interactions, and their effects on the surface heat fluxes, hurricane structure, and intensity. Different water depths and surface conditions are incorporated for a variety of experiments starting with a hurricane bogus embedded in a uniform easterly mean flow of 5 m s super(-1). A salient feature of hurricane-land surface water interaction is the local surface cooling near the hurricane core with the largest cooling behind and on the right side of the hurricane center. Unlike the surface cooling due to hurricane-ocean interaction, the largest cooling in hurricane-land surface water interaction can be much closer to the hurricane core. Without solar radiation during night, the surface evaporation dominates the local surface cooling. This causes a surface temperature contrast between the core area and its environment. During the day, the surface temperature contrast is enhanced due to additional influence from the reduced solar radiation under the core. Related to the local surface cooling, there is a significant reduction of surface evaporation with a near cutoff behind the hurricane center. A layer of half-meter water can noticeably reduce landfall decay although the local surface temperature around the hurricane core region is more than 4 degree C lower than in its environment. Further experiments indicate that an increase of roughness reduces the surface winds but barely changes the surface temperature and evaporation patterns and their magnitudes since the increase of roughness also increases the efficiency of surface evaporation.

AN - 36415978; 9171 AB - PURPOSE: The improvement of 15.5 miles of State Route (SR) 70 from south of Striplin Road to south of McGowan Parkway overcrossing in Sutter and Yuba Counties, California is proposed. SR 70 begins at the SR 70/90 wye, just north of Sacramento, and continues south to its terminus at SR 395 at Hallelujah Junction. The highway constitutes the primary route connecting Sacramento to Marysville. Three build alternatives and a No-Build Alternative are considered in this final EIS. All build alternatives closely follow existing SR 70 except in the vicinity of East Nicolaus. Alternative 1 would provide two new lanes east of the existing highway from the SR 70 /99 split to Striplin Road. Near Striplin Road, the two new lanes would transition to the west side of the existing highway and four new lands would be constructed to Marcum Road, utilizing land formerly used by the Sacramento Northern Railway. Alternative 2 would be similar to Alternative 1, except that the alignment would be shifted approximately 45 meters further to the west between Striplin and Marcum roads to avoid wetlands located immediately west of existing SR 70. Alternative 3, which is the preferred alternative, would also be similar to Alternative 1, except that the alignment would be shifted to the east between Striplin and Marcum roads, again to avoid the wetlands. Alternative 3 would utilize the existing SR 70 southbound lanes and add two new lands for northbound traffic. A two-lane frontage road would be constructed to the east of the new northbound lands to accommodate local traffic under Alternative 3. Regardless of the action alternative selected, an overcrossing would be provided at Marcum Road, where the highway would turn west to bypass the town of East Nicolaus before returning to the west side of existing SR 70 near Cornelius Avenue. An interchange would be constructed at Nicolaus Avenue and an overcrossing at Colnelius Avenue. North of Cornelius Avenue, two new lanes would be constructed to the west of the existing highway. An at-grade intersection, eventually to be replaced by an interchange, would be constructed at Berry and Kempton roads. Just north of Berry and Kepmton roads, the freeway would transition back to the east side of the existing roadway at the Bear River bridge. The Rio Oso Road intersection would be eliminated and frontage roads would be constructed from Rio Oso Road to the Berry/Kempton Interchange. At the Bear River, a new bridge would be constructed to the east of the existing bridge for the northbound lanes. The existing bridge would be widened to accommodate the southbound lanes. An at-grade intersection, eventually to be replaced by an interchange, would be constructed at Feather River Boulevard. The alignment would continue north with two new lanes on the east side of the existing highway. A second undrcrossing would continue north with two new lanes on the east side of the existing highway/ A second undercrossing at Algodon Road and a second overhead at Plumas Arboga Road would be constructed to accommodate the two new northbound lanes. At this point, the alignment would run between some high power electrical towers to the east and Plumas Arboga Road to the west and return to existing SR 70 just south of McGowan Parkway. Park-and-ride facilities have been recommended at Feather River Boulevard and Plumas Arboga and Algodon Roads. Cost of the project is estimated at $105.3 million. POSITIVE IMPACTS: Upgrading this section of SR 70 would allow it to complement the contiguous four lane section of the facility, improving traffic flow and, thereby, increasing travel speeds and reducing air pollutant emissions within the corridor. The bypass of East Nicolaus would probably remove through traffic from local streets in that community. NEGATIVE IMPACTS: Rights-of-way requirements for Alternative 3 would result in the displacement of 19 residences, five farms, 272.5 acres of farmland, 15.5 acres of wetlands and related waters, and 111 to 190 acres of floodplain. The bypass of East Nicolaus would probably reduce drive-by commerce along existing SR 70 in the area. The project could also affect the vernal pool tadpole shrimp and Swainson's hawk as well as potential habitat for the giant garter snake, steelheal trout, fall run Chinook salmon, vernal pool fairy shrimp, valley elderberry longhorn beetle, California red-legged frog, and northwestern pond turtle; all these species are federally protected. Interchanges and overcrossings would block views of agricultural lands, and removal of large riparian trees would further degrade visual aesthetics. Noise levels at a few sensitive receptors would increase by as much as 12 decibels. The highway would lie in a corridor containing 18 sites potentially affected by hazardous materials.

AN - 72917538; 15143789 AB - More than 300 air change rate experiments were completed in two occupied residences: a two-story detached house in Redwood City, CA, and a three-story townhouse in Reston, VA. A continuous monitor was used to measure the decay of SF6 tracer gas over periods of 1-18 hr. Each experiment first included a measurement of the air change rate with all exterior doors and windows closed (State 0), then a measurement with the single change from State 0 conditions of opening one or more windows. The overall average State 0 air change rate was 0.37 air changes per hour (hr(-1)) (SD = 0.10 hr(-1); n = 112) for the California house and 0.41 hr(-1) (SD = 0.19 hr(-1); n = 203) for the Virginia house. Indoor/outdoor temperature differences appeared to be responsible for the variation at the Virginia house of 0.15-0.85 hr(-1) when windows were closed. Opening a single window increased the State 0 air change rate by an amount roughly proportional to the width of the opening, reaching increments as high as 0.80 hr(-1) in the California house and 1.3 hr(-1) in the Virginia house. Multiple window openings increased the air change rate by amounts ranging from 0.10 to 2.8 hr(-1) in the California house and from 0.49 to 1.7 hr(-1) in the Virginia house. Compared with temperature differences and wind effects, opening windows produced the greatest increase in the air change rates measured in both homes. Results of this study indicate the importance of occupant window-opening behavior on a home's air change rate and the consequent need to incorporate this factor when estimating human exposure to indoor air pollutants.

AN - 71550269; 11883607 AB - A DNA glycosylase specific for UV radiation-induced pyrimidine dimers has been identified from the Chlorella virus Paramecium Bursaria Chlorella virus-1. This enzyme (Chlorella virus pyrimidine dimer glycosylase [cv-pdg]) exhibits a 41% amino acid identity with endonuclease V from bacteriophage T4 (T4 pyrimidine dimer glycosylase [T4-pdg]), which is also specific for pyrimidine dimers. However, cv-pdg possesses a higher catalytic efficiency and broader substrate specificity than T4-pdg. The latter excises 4,6-diamino-5-formamidopyrimidine (FapyAde), a UV radiation- and hydroxyl radical-induced monomeric product of adenine in DNA. Using gas chromatography-isotope-dilution mass spectrometry and y-irradiated DNA, we show in this work that cv-pdg also displays a catalytic activity for excision of FapyAde and, in addition, it excises 2,6-diamino-4-hydroxy-5-formamidopyrimidine (FapyGua). Kinetic data show that FapyAde is a better substrate for cv-pdg than FapyGua. On the other hand, cv-pdg possesses a greater efficiency for the extension of FapyAde than T4-pdg. These two enzymes exhibit different substrate specificities despite substantial structural similarities.

AN - 62293613; ED462928 AB - This report provides information on Americans' connectivity to the Internet, broadband services, and computers. Findings are based on the September 2001 U.S. Census Bureau's Current Population Survey--a survey of approximately 57,000 households and more than 137,000 individuals across the United States. The report shows the rapidly growing use of new information technologies across all demographic groups and geographic regions. Not only are many more Americans using the Internet and computers at home, they are also using them at work, school, and other locations for an expanding variety of purposes. The rate of growth of Internet use in the United States is currently two million new users per month. More than half of the nation is now online. In September 2001, 143 million Americans (about 54% of the population) were using the Internet--an increase of 26 million in 13 months. In September 2001, 174 million people (66% of the population) in the United States used computers. Children and teenagers use computers and the Internet more than any other group. Family households with children under the age of 18 are more likely to access the Internet (62%) than family households with no children (53%), and non-family households (35%). Computers at schools substantially narrow the gap in computer usage rates for children from high and low income families. Internet use is increasing for people regardless of income, education, age, races, ethnicity, or gender. While 80% of Americans access the Internet through dial-up service, residential use of broadband service is rapidly increasing. Forty-five percent of the population now uses e-mail, up from 35% in 2000. Approximately one-third of Americans use the Internet to search for product and service information (36%, up from 26% in 2000). Use of the Internet and computers at work has contributed to higher use levels at home.

Census 2000 Brief. AN - 62196225; ED469364 AB - This brief summarizes data from Census 2000 on the American Indian and Alaska Native (AI/AN) population and discusses its distribution at national, regional, and state levels. This information is intended for all levels of government to use in implementing and evaluating programs related to education, employment, health care, job training, civil rights, and housing. On April 1, 2000, 4.1 million persons--1.5 percent of the U.S. population--reported their race as AI/AN. This number included 2.5 million reporting AI/AN only and 1.6 million reporting AI/AN in combination with another race. Of all respondents who reported AI/AN, 43 percent lived in the West and 31 percent lived in the South. About 25 percent lived in California and Oklahoma combined. At 19 percent, Alaska had the highest proportion of AI/AN population, followed by Oklahoma (11 percent) and New Mexico (10 percent). American Indians and Alaska Natives were the majority of the population in 26 counties, located in eight states of the West and Midwest. Locations of clusters of counties with high AI/AN proportions are described. Among large cities, the largest AI/AN populations were found in New York and Los Angeles, which together accounted for 3.4 percent of the total AI/AN population. American Indian tribal groupings with 100,000 or more people were Cherokee, Navajo, Latin American Indian, Choctaw, Sioux, and Chippewa. Alaska Native tribal responses and patterns of mixed-tribal responses are also discussed. (Contains 11 data tables and figures.) (SV) AU - Ogunwole, Stella U.

We present new evidence from a compilation of over two decades of accurate satellite data that the top-of-atmosphere (TOA) tropical radiative energy budget is much more dynamic and variable than previously thought. Results indicate that the radiation budget changes are caused by changes in tropical mean cloudiness. The results of several current climate model simulations fail to predict this large observed variation in tropical energy budget. The missing variability in the models highlights the critical need to improve cloud modeling in the tropics so that prediction of tropical climate on interannual and decadal time scales can be improved.

Experiments were deployed on the forereef slope off Lee Stocking Island, Bahamas, for one and two years along two transects (AA and BA) in seven distinctive environments of deposition (EODs) along each transect: in sand channels on the platform top (15 m) and the platform edge (30 m), on ledges down the wall (70-88 m), on the upper (183 m-transect BA only) and lower (210-226 m) talus slope below the wall, and on the crest (256-264 m) and in the trough (259-267 m) of large sand dunes. Discoloration was by far the dominant taphonomic process over the two-year deployment period, with dissolution or maceration of shell carbonate a close second. Periostracum breakdown was not significant, nor was loss of shell weight. Chipped edges and breakage (assayed by the edge alteration variable) were much less common, but were important in some species. The degrees of edge alteration and dissolution were correlated with discoloration more frequently than expected by chance, emphasizing that the process of discoloration progressed in a coordinated fashion with the other two over time. The degree of burial or the interaction between degree of burial and water depth explained most of the trends observed in discoloration. The deep water sites, below the photic zone, including the talus slope and dune EODs, had very similar taphonomic signatures. Shells were characterized by a low degree of discoloration, little edge alteration, and varying degrees of dissolution. Photic zone sites, including the platform top and wall locations, followed the opposite trends, with the shallowest site, on the platform top, typically attaining the most extreme degree of alteration. The wall location was most similar to the platform top despite the greater depth and less rigorous physical and sedimentological regime. The platform edge occupied an intermediate position, likely due to the greater degree of burial that resulted in shells at this site being at least as frequently under aphotic conditions as under photic conditions. The data indicate that similar taphonomic signatures can be attained in distinctly different ways over a two-year exposure period, complicating the interpretation of taphofacies and the taphonomic process.

As previously reported, the dated cores reveal a century-long (1890-1990) rise and fall of chemical contamination in the Puget Sound. Further examination also reveals possible long-term processes that may have transported materials, such as arsenic, across basins. The Mussel Watch Program data begin where the core_end (late 1980's). Both cores and mussels from the Sound confirm that PCB concentrations have been declining over the past three to four decades. However, there have been no trends for most metals. Compared to mussels from other Pacific coastal sites those within Puget Sound and the Straits contain lower concentrations of several metals (arsenic and cadmium), similar concentrations of other metals, concentrations of PCBs that are similar to other urban areas, but extremely high concentrations of PAH's. To understand and derive benefit from contaminant management actions-, and, ultimately, to determine "how clean is clean enough?", these kinds of long-term region-wide contaminant monitoring programs should be maintained, if not enhanced.

Bioconcentration of pesticides by phytoplankton and zooplankton at the base of the aquatic food web may increase the persistence of pesticides in aquatic ecosystems and cause effects at higher trophic levels. This study examined the toxicity of a widely used agricultural pesticide, endosulfan, to Pseudokirchneriella subcapitatum (freshwater green alga) and Daphnia magna (freshwater cladoceran). We then investigated the potential of both plankton species to sequester endosulfan from their surrounding media. We also assessed the degree to which endosulfan is accumulated by D. magna via food (endosulfan-contaminated P. subcapitatum). A 96-h growth rate EC50 of 427.80 mu g/L endosulfan was determined for P. subcapitatum, whereas a 24-h immobilization EC50 of 366.33 7g/L endosulfan was determined for D. magna. The 5-h EC50s for filtration and ingestion in D. magna were 165.57 mu g/L and 166.44 mu g/L, respectively. An average bioconcentration factor (BCF) of 2,682 was determined for P. subcapitatum exposed to 100 mu g/L endosulfan for 16 h. An average BCF of 3,278 was determined for D. magna in a 100 mu g/L endosulfan water-only exposure. There was negligible uptake of endosulfan by D. magna feeding on contaminated algae in clean water (BCF similar to 0). Different proportions of parent isomers (endosulfan I and II) and the primary degradation product (endosulfan sulfate) were detected among treatments. Endosulfan was rapidly accumulated and concentrated from water by P. subcapitatum and D. magna neonates. Endosulfan contained in phytoplankton, however, was not bioaccumulated by zooplankton. These findings may prove useful in assessing ecosystem risk, because uptake from the water column appears to be the dominant route for bioconcentration of endosulfan by zooplankton.

Seven species were observed, including Pseudo-nitzschia pungens (Grunow ex Cleve) Hasle, P. multiseries (Hasle) Hasle, P. australis Frenguelli, P. fraudulenta (Cleve) Hasle, P. cf. heimii Manguim, P. pseudodelicatissima (Hasle) Hasle, and P. delicatissima (Cleve) Heiden. The coastal Pseudo-nitzschia species assemblages differed significantly from those observed within embayments. The dominant species observed at coastal sites were P. pseudodelicatissima and P. cf. heimii. Pseudo-nitzschia assemblages found in embayments included one or more of the following species: P. pungens, P. multiseries, P. australis, P. pseudodelicatissima, and P. fraudulenta. The nuclear large subunit rRNA gene was sequenced for six of the seven species identified. This sequence revealed that P. multiseries, P. pungens, P. australis, and P. heimii were genetically similar to those found in California, whereas P. delicatissima and P. pseudodelicatissima were distinct from the California isolates. Although the concentrations of DA in razor clams along Washington State coasts have exceeded regulatory limits several times since 1991, levels of DA in shellfish from Washington State embayments have not yet exceeded regulatory limits. The widespread presence of toxin-producing Pseudo-nitzschia species suggests, however, that toxic blooms are likely to occur within embayments in the future. In conjunction with the monitoring of environmental conditions conducive to toxic bloom formation, the development of species-specific probes for rapid and accurate detection of potentially toxic Pseudo-nitzschia species in this region would enable the forecasting of a toxic event before DA accumulates in shellfish, thereby reducing the impacts to coastal communities.

AN - 18554550; 5350653 AB - While many recovery programs for threatened species focus on acute sources of mortality, understanding some of the evolutionary processes of these species may lead to more effective recovery efforts, especially in cases where human-induced disturbances have resulted in artificial selection pressures. We developed a Monte Carlo test to determine whether Snake River spring/summer chinook salmon (Oncorhynchus tshawytscha) experienced selective mortality as a function of their juvenile length and timing of downstream migration. Actively migrating juvenile fish (smolts) were captured, tagged, and released in 1995 and 1996 approximately 700 km upstream from the Pacific Ocean, and returning adults were detected at the same location. We analyzed data from two groups of fish: those that migrated downstream in-river and those that were barged downstream as part of the juvenile-salmon transportation program. These groups were further separated into wild and hatchery fish. Length at release was significantly greater in returning adults than in the general population for fish that migrated downstream in-river (both wild and hatchery) or were transported (hatchery only). From the 1995 seaward migration, adult returns of both wild and hatchery fish that migrated in-river were composed of fish released significantly earlier than the general population. In contrast, the opposite trend existed for wild and hatchery transported fish. From the 1996 seaward migration, no significant difference in release date was found between returning adults and the original population for any of the groups analyzed. Fish length at migration is a result of factors encountered in early life stages but selectively determines mortality in the smolt-to-adult stage. Thus freshwater habitat improvements, such as salmon carcass supplementation, directed at increasing nutrient levels and thus fish length may result in an increase in overall survival. The development of hydroelectric dams in the migratory corridors of these fish has disrupted their arrival timing to the estuary. Mitigation efforts designed to shift arrival timing toward that experienced prior to impoundment may confer considerable survival benefits.

Total cover was measured as the combined areas of all the individual structures, viewed as shadows. I divided total cover by the bottom area of the tank to form C sub(t)/A sub(t), an index that measures the total amount of structure available in a given area for prey to hide behind. Cover quality was measured as the width of each individual structure divided by the width of the individual prey organism (C sub(w)/P sub(w)). This index measures how visible a prey organism is when hiding behind an individual structure. Both of these complexity indices are dimensionless and potentially applicable to any habitat type and habitat scale. I predicted that prey survivorship should increase hyperbolically with increasing C sub(t)/A sub(t), because increasing the amount of structure within a habitat increases the amount of the habitat blocked off from detection, but with diminishing returns. Past experiments demonstrated that increased C sub(t)/A sub(t) does increase prey survivorship, but the shape of the relationship was unclear. I also predicted that prey survivorship should increase hyperbolically with increasing C sub(w)/P sub(w). I predicted this by simulating a prey organism hiding behind a flat structure being viewed by a predator from all potential angles. In this simple simulation, the `average amount of the prey hidden from view' increased hyperbolically with increasing C sub(w)/P sub(w) to an asymptote of 0.5. I performed 2 experiments to test these ideas. In the first, I kept C sub(t)/A sub(t) constant between treatments and varied the width of the individual structures relative to the width of shrimp prey Paleomonetes spp. In the second experiment, I kept the inter-structural space widths nearly constant between treatments and varied C sub(t)/A sub(t). The prey for the second experiment were mobile amphipods. I tested the hypothesis that survivorship and treatment were independent using log-linear models for both experiments. I found that there was no significant difference in survivorship between treatments for the C sub(w)/P sub(w) experiment, and there was a significant difference in survivorship between treatments for the C sub(t)/A sub(t) experiment. The relationship between C sub(t)/A sub(t) and prey survivorship appeared to increase hyperbolically, as predicted. Finally, I used the results of the C sub(t)/A sub(t) experiment, and results from a past study, to form a modeled regression equation of the survivorship surface for large F. heteroclitus feeding on amphipods for various levels of C sub(t)/A sub(t) and Sp/Pr (inter-structural space size/predator width). This equation was highly significant, and fit the data well. In this regression, amphipod survivorship increased hyperbolically with increasing C sub(t)/A sub(t), and decreased sigmoidally with increasing Sp/Pr.

However, the effects of over-fishing, environmental change, fish community dynamics and other factors that have altered the trophic ecology of cod are not well understood. We present an analysis of the trophic patterns of cod in the northeast US shelf ecosystem from a 25 yr time series of food habits data. Additionally, we compared the diet of this species with the spatio-temporal distribution of its prey species and evaluated prey preference over time. Atlantic cod exhibit an omnivorous diet; we assessed the temporal, spatial, and ontogenetic trends in this diet by examination of > 15000 stomachs. Ontogenetic shifts in diet were observed; early juveniles consumed more pelagic than benthic invertebrates, medium cod consumed benthic invertebrates and fish, and larger cod consumed larger amounts of fish. Cannibalism also increased with ontogeny. Diet shifted significantly over a period of 3 decades, concurrent with changes in forage species abundance and distribution. Most of the major prey species were eaten in periods when they had high spatio-temporal overlap with cod and were abundant, indicating opportunistic feeding by cod. Similar to many other ecosystems, cod prefer sand lance, Cancer spp. crabs and herring, regardless of the abundance or spatio-temporal overlap with these prey species. It is unclear whether the observed changes in the trophic dynamics of cod have broad implications for cod populations, yet the evidence does suggest that cod are not likely to influence the abundance and distribution of their prey populations in this ecosystem.

Bacterial artificial chromosome (BAC) DNA was used as a source of large supercoiled and open circular (relaxed) forms. The open circles above approximately 50 kbp were trapped at the sample wells of 1% agarose gels during electrophoresis at 3 V/cm. Field inversion gel electrophoresis (FIGE) was used to relieve the trapping of the open circles in the gels. Using FIGE (30 s forward pulse time), open circles with sizes of 115 and 220 kbp required reverse pulse times of 3 and 6 s, respectively, to free the circles from open-ended gel fibers. A minimum in the gel velocity of the open circles was measured at approximately 20 kbp. Open circles below approximately 20 kbp migrated slower than the supercoiled forms, and above 20 kbp the order was reversed. These results indicate that when the size of the open circles exceeded the average pore size of a gel and it was forced to span multiple pores, the open circles gained a mobility advantage. Decreasing the ionic strength of the electrophoresis buffer significantly decreased the mobility of the smaller circles and slightly increased the mobility of the larger circles.

Knowing the ratio of effective to census size, N sub(e) / N , is useful for estimating the effective size of a population from census data and for examining how different ecological factors influence effective size. Two different multigenerational ratios have been used in the literature based on either the arithmetic mean or the harmonic mean in the denominator. We clarify the interpretation and meaning of these ratios. The arithmetic mean N sub(e) / N ratio compares the total number of real individuals to the long-term effective size of the population. The harmonic mean N sub(e) / N ratio summarizes variation in the N sub(e) / N ratio for each generation. In addition, we show that the ratio of the harmonic mean population size to the arithmetic mean population size provides a useful measure of how much fluctuation in size reduced the effective size of a population. We discuss applications of these ratios and emphasize how to use the harmonic mean N sub(e) / N ratio to estimate the effective size of a population over a period of time for which census counts have been collected.

The first study of paternity in a sea turtle species used allozyme analysis to suggest multiple paternity in loggerhead turtle (Caretta caretta) clutches in Australia. Subsequent studies indicated that the frequency of multiple paternity varies from species to species and perhaps location to location. This study examined fine-scale population structure and paternal contribution to loggerhead clutches on Melbourne Beach, FL, USA using microsatellite markers. Mothers and offspring from 70 nests collected at two locations were analysed using two to four polymorphic microsatellite loci. Fine-scale population differentiation was not evident between the sampled locations, separated by 8 km. Multiple paternity was common in loggerhead nests on Melbourne Beach; 22 of 70 clutches had more than one father, and six had more than two fathers. This is the first time that more than two fathers have been detected for offspring in individual sea turtle nests. Paternal genotypes could not be assigned with confidence in clutches with more than two fathers, leaving the question of male philopatry unanswered. Given the high incidence of multiple paternity, we conclude that males are not a limiting resource for this central Florida nesting aggregate.

Results are presented of an observing system simulation (OSS) to determine whether three-dimensional water vapor fields could be recovered from a high-resolution network (e.g., with 40-km spacing) of GPS receivers, in combination with surface moisture observations and a limited number of moisture soundings. The paper describes a three-dimensional variational analysis (3DVAR) that recovers the moisture field from the slant integrated water vapor and other observations. Comparisons between "nature" moisture fields taken from mesoscale models and fields recovered using 3DVAR are presented. It is concluded that a high-resolution network of GPS receivers may allow diagnosis of three-dimensional water vapor, with applications for both positioning and mesoscale weather prediction.

In response to these petitions and the more general concerns for the status of Pacific salmon throughout the region, NMFS initiated biological status reviews for all species of anadromous salmonids in the Pacific Northwest. In December 1997 the NMFS Northwest Fisheries Science Center published a status review from the Chum Salmon Biological Review Team (BRT) that described four distinct population segments or evolutionarily significant units (ESUs) of chum salmon: Strait of Georgia/Puget Sound Hood Canal Summer-Run, Pacific Coast, and Columbia River. The BRT reviewed population abundance data and other risk factors for these ESUs and concluded that two (Hood Canal Summer-Rum and Columbia River) were likely to become endangered in the foreseeable future. In 1999 summer chum salmon in Hood Canal were listed as threatened under the ESA. This presentation summarizes both the original information from the 1997 chum salmon status review, and new information on the Hood Canal Summer-Run and Columbia River ESUs received since the listing in the federal register notice.

Adult male English sole collected near urban areas may provide the answer AN - 17282415; 5779496 AB - Vitellogenin (Vtg) is a yolk protein produced in the liver of oviparous animals in response to estrogen. Its synthesis is normally observed only in sexually mature females with developing eggs, however male animals can synthesize Vtg when exposed to exogenous estradiol or to substances that mimic estrogens. Thus, the abnormal production of Vtg in male animals can be used as a biological indicator for exposure to environmental estrogens. As part of the Puget Sound Ambient Monitoring Project (PSAMP), we collected plasma from adult male English sole from numerous urban embayments in Puget Sound between 1997-99. Among the sites sampled are areas with elevated levels of compounds in bottom sediments with suspected estrogenic activity, such as certain phthalates, DDTs, and PCB congeners (Sinclair Inlet, Duwamish Waterway, Elliott Bay). Male English sole plasma from these sites and several clean reference sites are being analyzed utilizing a validated enzyme-linked immunoassay (ELISA) for plasmatic Vtg in English sole. The presence or absence of Vtg in these samples will help to answer the above question. The results of this study will be presented and the implications discussed.

This includes assessment of the impacts of exposure to toxic chemicals on fish and their critical habitat. This analysis was conducted to assist resource managers in the NMFS in determining when fish are exposed to potentially harmful concentrations of one of the most common environmental contaminants, polycyclic aromatic hydrocarbons (PAHs). Effects thresholds were estimated primarily through segmented regression of site-specific sediment PAH concentrations and associated disease prevalences in a resident fish species, English sole. The analyses and supporting data encompasses several endpoints, including DNA damage, liver lesions, and impacts on growth and reproduction. In general, liver lesion prevalences, DNA adduct levels, and impacts on growth and reproduction were minimal at sediment PAH concentrations at or below 1000 ppb. Above 1000 ppb, there appears to be a substantial increase in the risk of contaminant-related injury to English sole.

We examined patterns of habitat use for newly settled red drum at six sampling areas in Galveston Bay; two areas had seagrass beds and four areas had no seagrass. We measured densities in different habitat types using epibenthic sleds and enclosure samplers. Peak recruitment of young red drum to the estuary occurred during September through December. Highest densities of new settlers were found in seagrass meadows (primarily Halodule wrightii), but when seagrass was absent, the highest densities of red drum occurred along the Spartina alterniflora marsh edge interface. Densities were relatively low on nonvegetated bottom away from the marsh edge. We also examined density patterns in other habitat types at selected sampling areas and found no red drum within marsh vegetation away from the marsh edge interface (5 and 10 m into the marsh interior). Oyster reef Crassostrea virginica was sampled using lift nets, and we found no red drum using this habitat, although adjacent seagrass and marsh interface habitats were used. Even though red drum densities in marsh edge were low relative to seagrass, the large areal extent of marshes in the bay complex probably makes marsh edge the most important nursery habitat for red drum in Galveston Bay.

But the detection of anthropogenically forced changes in flooding is difficult because of the substantial natural variability; the dependence of streamflow trends on flow regime further complicates the issue. Here we investigate the changes in risk of great floods--that is, floods with discharges exceeding 100-year levels from basins larger than 200,000 km super(2)--using both streamflow measurements and numerical simulations of the anthropogenic climate change associated with greenhouse gases and direct radiative effects of sulphate aerosols. We find that the frequency of great floods increased substantially during the twentieth century. The recent emergence of a statistically significant positive trend in risk of great floods is consistent with results from the climate model, and the model suggests that the trend will continue.

AN - 71406180; 11790099 AB - Crystals of pyruvate phosphate dikinase in complex with a substrate analogue inhibitor, phosphonopyruvate (K(i) = 3 microM), have been obtained in the presence of Mg(2+). The structure has been determined and refined at 2.2 A resolution, revealing that the Mg(2+)-bound phosphonopyruvate binds in the alpha/beta-barrel's central channel, at the C-termini of the beta-strands. The mode of binding resembles closely the previously proposed PEP substrate binding mode, inferred by the homology of the structure (but not sequence homology) to pyruvate kinase. Kinetic analysis of site-directed mutants, probing residues involved in inhibitor binding, showed that all mutations resulted in inactivation, confirming the key role that these residues play in catalysis. Comparison between the structure of the PPDK-phosphonopyruvate complex and the structures of two complexes of pyruvate kinase, one with Mg(2+)-bound phospholactate and the other with Mg(2+)-oxalate and ATP, revealed that the two enzymes share some key features that facilitate common modes of substrate binding. There are also important structural differences; most notably, the machinery for acid/base catalysis is different.

AN - 36411990; 9135 AB - PURPOSE: The implementation of a fishery management plan (FMP) for west coast fisheries for highly migratory species (HMS) is proposed. The FMP would manage five species of tuna, five species of sharks, striped marlin, swordfish, and dorado (dolphinfish). Tuna species include north Pacific albacore tuna, eastern Pacific yellowfin tuna, bigeye tuna, skipjack tuna, northern and bluefin tuna. Shark species include common thresher shark, pelagic thresher and bigeye thresher sharks, shortfin mako shark, and blue shark. Commercial and recreational fisheries for HMS would be managed under the FMP. Commercial gear would include surface hood and line, drift gillnet, harpoon, longline, and purse seine gear. The FMP would provide for the definition and prevention of overfishing, description and protection of essential fish habitat, and documentation and minimization of bycatch and interactions with protected species, including marine mammals, birds, and turtles. The FMP is a framework plan that would contain some specific measures but would also authorize actions to be taken in the future following specific procedures without amending the FMP. In addition, the FMP includes a set of proposed initial fishery conservation and management measures. The FMP would provide for permits for commercial fisheries, logbook requirements for commercial and charter fisheries, prohibitions for landing of certain bycatch species, harvest guidelines for certain shark species, prohibition of the sale of striped marlin, a recreational catch-and-release program, and restrictions on the use of drift fillnets, pelagic longline gear, and purse seines. POSITIVE IMPACTS: FMP implementation would promote international efforts for the long-term conservation and sustainable use of HMS fisheries, provide a stable supply of high quality fish to the public, minimize economic waste and adverse impacts on fishing communities when adopting conservation and management measures, provide viable and diverse commercial fisheries and recreational fishing opportunities, minimize bycatch and avoid discard, prevent overfishing and rebuild overfished stocks, collect biological information on the fisheries through a long-term research program, promote effective monitoring and enforcement, minimize gear conflicts, and allocate harvest fairly and equitably among commercial, recreational, and charter fisheries for HMS if allocation becomes necessary. NEGATIVE IMPACTS: Quota allocations and other restrictions could result in economic hardships for some commercial users of the fisheries, and limitations on recreational access to the fishery could affect recreational fishing in some cases.

AN - 36419208; 9123 AB - PURPOSE: The establishment of the San Francisco Bay National Estuarine Research Reserve in Contra Costa, Marin, and Solano counties, California is proposed. The San Francisco estuary is of major importance ecologically and economically as the centerpiece of one of the larger metropolitan areas in the country. The estuary lies at the terminus of the Sacramento and San Joaquin river systems, which, together, drain almost 40 percent of the land area of California. The estuary covers some 1,600 square miles and occupies the only complete breach of the Coastal Range, a 400-mile-long mountain chain extending from the coast to the Central Valley. A variety of terrestrial, wetland, and aquatic habitats are incorporated into the proposed boundaries of the reserve. Several threatened, endangered, and candidate species of plants and animals occur within the proposed boundaries. In addition to such diversity of natural resources, the reserve would also include significant historical and archaeological sites. Three areas (China Camp State Park, Rush Ranch Open Space Preserve, and Browns Island Regional Shoreline) totaling 4,305 acres would be designated as component sites of the reserve. The lead institution for the reserve would be the Romerg Tiburon Center, an off-campus research and teaching marine laboratory operated by San Francisco State University. The administrative plan would establish an integrated management approach for the San Francisco Bay reserve among the institutional? landholders within the region. The reserve manager would be the principal administrator and would ensure that the policies contained within the reserve management plan were followed. During the first five years of plan implementation, the reserve would hire staff; establish the management, research, and education advisory committees; implement a system-wide monitoring program; implement a graduate fellowship program complete a site profile; develop decision maker workshops and implement the necessary step toward creating the San Francisco Bay Coastal Training Institute; work with reserve partners to establish a coordination plan to either integrate existing volunteer programs or create new volunteer programs as needed; undertake a detailed facilities plan; undertake a stewardship plan, including components for restoration and rehabilitation; and develop outreach and educational materials for target audiences. In addition to the preferred alternative, the draft EIS of June 2001 considered a No Action Alternative, alternative reserve boundaries, and alternative management options. This draft supplement provides additional information regarding commercial navigation and socioeconomic issues. POSITIVE IMPACTS: Designation of the reserve components would protect and preserve economically and ecologically valuable and scientifically significant plant, animal, aquatic, and terrestrial resources. Research programs associated with the reserve would contribute to an understanding of estuarine environments and their relation to human populations. Additional recreational and educational opportunities would be provided for the general public. NEGATIVE IMPACTS: NONE. LEGAL MANDATES: Coastal Zone Management Act of 1972 (43 U.S.C. 1241).

Preparation date: January 4, 2002 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - FISHERY MANAGEMENT PLAN FOR PELAIC SARGASSUM HABITAT OF THE SOUTH ATLANTIC REGION (DRAFT SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF DECEMBER 1998). AN - 16341457; 9121 AB - PURPOSE: The establishment of a fishery management plan for pelagic Sargassum habitat in the South Atlantic U.S. Exclusive Economic Zone (EEZ) is proposed. The management unit is the population of pelagic Sargassum occurring within the jurisdiction of the South Atlantic Fishery Management Council along the U.S. Atlanic coast from the east coast of Florida, including the Atlantic side of the Florida Keys, to the North Carolina/Virginia border and within state waters of North Carolina, South Carolina, Georgia, and the east coast of Florida. The plan forwarded in the final EIS of December 1998 would not specify a maximum sustainable yield at the outset due to limited data on the affected species. Overfishing would be defined as occurring when any harvest occurs of when the fishing mortality rate is greater than zero. Essential fish habitat would be defined as where such habitat occurs in the EEZ or state waters. In addition, the Gulf Stream would be considered essential fish habitat since it provides a mechanism to disperse Sargassum. Moreover, the U.S. would pursue all other options to protect Sargassum in international waters. Essential Fish Habitat-Habitat Areas of Particular Concern for pelagic Sargassum would include all EEZ waters under the South Atlantic Council's jurisdiction as well as state waters containing pelagic Sargassum. All harvest or possession of Sargassum would be prohibited south of the North Carolina/South Carolina border. Harvest would be limited to 50,000 pounds wet weight (determined dockside after being offloaded) in the area bounded by the latitude lines representing the North Carolina/Virginia border and the North Carolina/South Carolina border and the longitude line representing 100 miles seaward of the North Carolina shoreline until January 1, 2001, at which date harvest would be prohibited entirely. In addition, harvesters would be required to acquire a federal permit, allow on-board observers if requested, maintain logbooks, contact the National Marine Fisheries Service Southeast Regional Law Enforcement Office when leaving and returning to port, and ensure that nets used to harvest Sargassum have four-inch stretch mesh or larger mesh. This supplement to the final EIS addresses the conflicting relationship between Sargassum as essential fish habitat (EFH) for federally managed finfish species and Sargassum as a fishery resource. Two to six alternatives are provided for each of eight management action categories; a No Action Alternative is considered for each category. Management action categories include establishment of the extent of the management unit, establishment of the maximum sustainable yield, establishment of the optimum yield establishment of overfishing thresholds, description and identification of EFH, description and identification of EFH-Habitat Areas of Particular Concern. Establishment of total allowable catch, and provision of harvest rules. POSITIVE IMPACTS: Overfishing would be prevented through the use of effective management controls. Data gathered during the early period of the management plan would allow for proper management of the fishery resource. NEGATIVE IMPACTS: Harvesters would suffer economic losses due to eventual closure of the fishery and to gear restrictions while the fishery remained open.

In the Northwest Atlantic, Atlantic cod, Gadus morhua, once the basis of a lucrative commercial fishery, have not recovered despite regulations imposed on the fishery to reduce harvest rates. One possible reason for the lack of recovery is that high predation pressure on juvenile and larval stages, particularly from species such as herring and mackerel, may regulate the abundance of cod. However, traditional methods used to identify larval cod and haddock often fail when applied to partially digested remains. Here, we described a DNA-based assay to identify the presence of digested cod remains from the stomachs of predatory fish species. After development, the assay was tested on two sets of field samples. Larval and juvenile cod were successfully detected in both tests.

The model demonstrates that a wide range of relationships between NP and mixed-layer nitrate is possible due to partial decoupling of nitrogen and iron cycles in the upper ocean. The shapes and slopes of these relationships are determined by the mode of physical forcing that introduces the most variability to the iron supply for a set of observations. When variability of upwelling fluxes is dominantly determined by changes in nutricline depth over changes in upwelling velocity, NP is a linear function of mixed-layer nitrate; whereas when variability in upwelling velocity dominates, NP takes on a hyperbolic function of nitrate. Fluctuations in atmospheric iron supply also introduce distinct patterns between NP and mixed-layer nitrate concentrations. Variability in nitrogen-to-iron ratios in exported organic matter, however, are not likely to drive large changes in NP or nitrate because of expected covariation with N:Fe ratios in upwelled source waters. Within surface waters of the equatorial Pacific, variability in physical forcing exists over a wide range of temporal and spatial scales. Tropical instability waves, equatorially trapped internal gravity waves and daily fluctuations in zonal winds all predominantly drive short-term variability in upwelling velocities with minor changes to nutricline depth. El Nino cycles and Kelvin waves produce longer-term variability in nutricline depth with minimal changes in upwelling velocities. Comparisons of observed NP-to-nitrate relationships for individual cruises to the observed modes of physical forcing match model predictions quite well, with Zonal Flux and Flupac serving as end-member examples of these processes. These results support those from statistical studies (Aufdenkampe et al., Deep-Sea Research (2002) 2619-2648, Aufdenkampe et al., Global Biogeochemical Cycles 15 (2002) 101-113), by offering a mechanistic explanation for observations that the relationship between NP and nitrate is more variable between cruises than within cruises.

Most of the CO (sub 2) evasion takes place in the upwelling-influenced region in the eastern Pacific, while atmospheric and sea-surface partial pressures of CO (sub 2) are near equilibrium in the warm pool, located to the west. Large changes in the surface area of the upwelling region, which occur as a result of the ENSO (El Nino--Southern Oscillation) phenomenon, account for up to 70% of the interannual variability in the net air-sea flux of CO (sub 2) . On average, the export of biological production, which is approximately the same as new primary production, is similar to that of CO (sub 2) evasion (0.8-1.0 Pg C yr (super -1) ), but there is less temporal variability due to the very slow uptake of new macronutrients in the equatorial ecosystem. As in other tropical ecosystems, both the warm pool and upwelling areas are characterized by: (i) the dominance of picophytoplankton, and (ii) the steady state, achieved by the balance between predation and growth. In addition to the basic tropical population of nano- and picoplankton, larger phytoplankton are more abundant in the nutrient-replete waters of the upwelling region with the result that biomass, mean organism size and export fluxes are greater than in the nutrient-depleted waters of the warm pool. However, the difference in export flux of carbon between the two regions is rather modest (2-4 fold per unit area) because of the limitation of primary production in the upwelling zone by iron and, possibly, other nutrients. The latter is a typical HNLC (high-nutrient-low-chlorophyll) zone with very low rates of uptake of macronutrients and an essentially constant export flux of carbon due to the 'biological pump'. This general pattern is temporarily disturbed by the passage of equatorial Kelvin waves and tropical instability waves (TIW) in the upwelling region through horizontal advection and possible inputs of micronutrients from the deeper layers. Finally, low-frequency variations on decadal time scales could influence the values of the CO (sub 2) evasion and the 'biological pump'. Studying their impact will require long-term monitoring.

Equatorial SiOH (sub 4) concentrations are shown to be the product of both geochemical and physical interactions with chemical processes, occurring in at least three regions remote from the equatorial Pacific, and physical delivery processes from the equatorial undercurrent (EUC) to the surface layer varying over a range of time scales. The EUC was partitioned into upper and lower portions, the upper providing source water to the central upwelling area and the lower crossing the Pacific without upwelling and thought to reenter the surface along the coast of Peru and to the eastern equatorial upwelling area. The source waters from the North Pacific, the north equatorial countercurrent (NECC) and from the South Pacific, the New Guinea coastal undercurrent (NGCUC) also were partitioned according to source for the upper and lower EUC. Mean concentrations and ranges of nutrients for each source partition were obtained from field data. Current flow and advective data output from a 3-D physical model were used with the field nutrient data to calculate nutrient fluxes into the EUC. Although the inflow of water from the north and south were approximately equal, the stronger asymmetric distribution of Si(OH) (sub 4) compared to NO (sub 3) resulted in identifying the South Pacific source as only 30% of the total supply of Si(OH) (sub 4) to the EUC and the cause of a low Si(OH) (sub 4) :NO (sub 3) condition. These results suggest a coupling between Southern Ocean productivity, equatorial productivity, and the efflux of CO (sub 2) to the atmosphere from the equatorial upwelling system.

The two regions are separated by well-defined fronts in salinity, pCO (sub 2) , and macronutrients. Both the input of macronutrients in the two regions and their zonal extension are influenced primarily by the El Nino Southern Oscillation (ENSO) variability, which may be depicted by the Southern Oscillation Index (SOI). Thus, a quantitative relationship can be established between the longitude of the front and the SOI (Geophys. Res. Lett. 23 (1996) 1781-1784), allowing an assessment of the zonal extension of the two regions. In the PEQD, equatorial transects have shown that there is much temporal and spatial stability of biomass and fluxes of the biological pump, regardless of variations in macronutrient concentrations. This is a consequence of the High Nutrient Low Chlorophyll (HNLC) status of the waters, where primary production is not limited by the input of macronutrients. Moreover, the lack of an E-W gradient in the biological parameters supports the view that micronutrient inputs also should be more or less constant with longitude along the equator. A review of temporal variability on scales ranging from ENSO cycles to diel cycles leads to the conclusion that much of the biomass and flux variations along equatorial transects may be ascribed to temporary meridional transport by Tropical Instability Waves (TIW). In the warm pool, primary production is regulated by the input of macronutrients to the photic zone. These inputs from the deep nutricline depend on the ENSO cycle and temporary events. However, primary production is less than in the PEQD. A monthly estimate of the biological pump was made for the period 1980-2000 and the 1 degrees N-1 degrees S band of the divergence, west of the Galapagos Islands, on the assumption that: the longitude of the front was directly related to the SOI; there were no zonal variations in biological parameters; and mean rate values could therefore be used for primary production, new production, particle sinking and fluxes due to diel migration. The average longitude of the front was 178 degrees W, and mean new production was 106-134 Mt C yr (super -1) ; it was 76-96 Mt C yr (super -1) during strong El Nino years and 114-144 Mt C yr (super -1) during other years. These variations between the two ENSO situations are less than those of published CO (sub 2) fluxes to the atmosphere, a result that can be ascribed to the particularly stable HNLC system.

Mean total foraminiferal fluxes (TFFs) were 171 and 97 shells m (super -2) day (super -1) at Sites N1 (2 degrees 59.8'N, 135 degrees 01.5'E) and N2 (4 degrees 07.5'N, 136 degrees 16.6'E), respectively. The seasonal change in TFFs was much higher than for organic matter (OM) and carbonate fluxes. The major species of planktonic foraminifera were Pulleniatina obliquiloculata, Neogloboquadrina dutertrei, Globigerinoides sacculifer, Globigerinella aequilateralis and Globigerinoides ruber. Symbiont-bearing species and N. dutertrei were predominant in the western equatorial Pacific warm pool. Comparison between the warm pool and upwelling (Deep-Sea Research II 43 (1996) 1257, Mar. Micropaleontology 33 (1998) 157) indicates that the foraminiferal assemblage trapped at the western equatorial Pacific warm pool was comparable with the South Equatorial and subtropical assemblages during a plankton tow study conducted at 140 degrees W in 1992. It suggests that fairly oligotrophic conditions prevailed in the western equatorial Pacific warm pool in association with terrestrial nutrient inputs or temporary mixing by wind bursts. The OM flux was more positively correlated with the <63 mu m carbonate fraction, mainly composed of coccoliths (r=0.87) and biogenic opal, which suggests that OM fluxes were more affected by phytoplankton productivity. Although food availability is generally important for foraminiferal production, TFFs were poorly correlated with OM fluxes at Sites N1 and N2, which is partly attributed to the significant influence of symbiont photosynthesis. The delta (super 18) O values of P. obliquiloculata and N. dutertrei showed maxima in association with high OM fluxes during Period 2 (from August to October) and Period 4 (from late December to April) at Site N1, reflecting thickening of the mixed layer, following wind bursts. G. sacculifer showed a lunar reproduction cycle, when, between July and October, carbonate production was more predominant than biogenic opal production. A similar profile was evident for G. ruber, Orbulina universa and G. aequilateralis. These four species are generally predominant at low latitudes. Therefore, the lunar reproduction cycle may significantly affect the fluctuation in carbonate production in the equatorial ocean. Abstract Copyright (2002) Elsevier, B.V. JF - Deep-Sea Research.

The ecosystem model consisted of 10 components (nitrate, silicate, ammonium, small phytoplankton, diatom, micro- and meso-zooplankton, detrital nitrogen and silicon, and total CO (sub 2) ). The ecosystem model was forced by the area-averaged (5 degrees S-5 degrees N, 90 degrees W-180 degrees , the Wyrtki Box) annual mean upwelling velocity and vertical diffusivity obtained from a three-dimensional circulation model. The model was capable of reproducing the low-silicate, high-nitrate, and low-chlorophyll (LSHNLC) conditions in the equatorial Pacific. The linkage to carbon cycle was through the consumption of assimilated nitrate and silicate (i.e. new productions). Model simulations demonstrated that low-silicate concentration in the equatorial Pacific limits production of diatoms, and it resulted in low percentage of diatoms, 16%, in the total phytoplankton biomass. In the area of 5 degrees S-5 degrees N and 90 degrees W-180 degrees , the model produced an estimated sea-to-air CO (sub 2) flux of 4.3 mol m (super -2) yr (super -1) , which is consistent with the observed results ranging of 1.0-4.5 mol m (super -2) yr (super -1) . The ammonium inhibition played an important role in determining the nitrogen cycle in the model. The modeled surface nitrate concentration could increase by a factor of 10 (from 0.8 to 8.0 mmol m (super -3) ) when the strength of the ammonium inhibition increased from psi =1.0 to 10.0 (mmol m (super -3) ) (super -1) . The effects of both micro- and meso-zooplankton grazing were tested by varying the micro- and meso-zooplankton maximum grazing rates, G1 (sub max) and G2 (sub max) . The modeled results were quite sensitive to the zooplankton grazing parameters. The current model considered the role of iron implicitly through the parameters that determine the growth rate of diatoms. Several iron-enrichment experiments were conducted by changing the parameter alpha (the initial slope of the photosynthetic rate over irradiance at low irradiance), K (sub Si(OH) (sub 4) ) (half-saturation concentration of silicate uptake by diatom), and mu 2 (sub max) (the potential maximum specific diatom growth rate) in the regulation terms of silicate uptake by diatom. Within the first 5 days in the modeled iron-enrichment experiment, the diatom biomass increased from 0.08 to 2.5 mmol m (super -3) , more than a factor of 30 increase. But the diatom populations crashed 2 weeks after the experiment started, due to exhaustion of available silicate and increased mesozooplankton population. The modeled iron-enrichment experiments produced several ecological behaviors similar to these observed during the IronEx-2. Abstract Copyright (2002) Elsevier, B.V. JF - Deep-Sea Research.

For the first time, we are able to determine how processes occurring in the western portion of the equatorial Pacific impact the sea-air fluxes of CO (sub 2) in the central and eastern regions. These 8 years of data are compared with the decade of the 1980s. Over this period, surface-water pCO (sub 2) data indicate significant seasonal and interannual variations. The largest decreases in fluxes were associated with the 1991-94 and 1997-98 El Nino events. The lower sea-air CO (sub 2) fluxes during these two El Nino periods were the result of the combined effects of interconnected large-scale and locally forced physical processes: (1) development of a low-salinity surface cap as part of the formation of the warm pool in the western and central equatorial Pacific, (2) deepening of the thermocline by propagating Kelvin waves in the eastern Pacific, and (3) the weakening of the winds in the eastern half of the basin. These processes serve to reduce pCO (sub 2) values in the central and eastern equatorial Pacific towards near-equilibrium values at the height of the warm phase of ENSO. In the western equatorial Pacific there is a small but significant increase in seawater pCO (sub 2) during strong El Nino events (i.e., 1982-83 and 1997-98) and little or no change during weak El Nino events (1991-94). The net effect of these interannual variations is a lower-than-normal CO (sub 2) flux to the atmosphere from the equatorial Pacific during El Nino. The annual average fluxes indicate that during strong El Ninos the release to the atmosphere is 0.2-0.4 Pg C yr (super -1) compared to 0.8-1.0 Pg C yr (super -1) during non-El Nino years.

NP measured along the equator during the Zonal Flux and Flupac cruises using (super 15) NO (sub 3) incubation methods is presented in this paper and compared to similar data from seven previously published cruises to the tropical Pacific. The Zonal Flux cruise found a strong zonal gradient of increasing NP to the east that followed increasing nitrate inventories. NP values ranged from 0.8 and 3.8 mmol N m (super -2) d (super -1) from 165 degrees E to 150 degrees W, respectively. During the 7-day Flupac Time Series II at 150 degrees W, NP measurements also showed strong variability, ranging from 1.9 to 3.6 mmol N m (super -2) d (super -1) , despite relatively uniform nitrate. Both cruises observed a previously measured but seldom discussed trend for f-ratios to increase substantially at the limits of the euphotic zone (0.1% E (sub 0) ). Multiple linear regression (MLR) analyses of areal, depth-integrated data from 121 stations in the tropical Pacific previously have showed that variability in primary production (or chlorophyll), ammonium, nitrate and temperature together could "explain" 79% of the variability in NP (Aufdenkampe et al., Global Biogeochem. Cycles 15 (2001) 101). In the present study, the MLR method was extended to depth specific data, where the same variables were shown to explain 77% of nitrate uptake variability. MLR was then used to investigate differences between individual cruises in the relationships of NP to these variables. Similar to MLR results with combined data from all cruises, MLR of individual cruises also found primary production (or chlorophyll), ammonium and nitrate to be consistently the best variables to explain variability in areal NP, exhibiting R (super 2) values from 0.45 to 0.92. However, nitrate is consistently a much stronger predictor of NP within cruises than between cruises. Other lines of evidence--including plots of each property vs. NP and vs. standard residuals of the all-cruise MLR, and differences in MLR partial slopes for individual cruises--together demonstrate that the relationship of NP to nitrate exhibits subtle but real differences from one cruise to the next. Zonal Flux and Flupac sampled the two extremes of this observed NP-to-nitrate variability. Abstract Copyright (2002) Elsevier, B.V. JF - Deep-Sea Research.

AN - 72184560; 12382728 AB - Radiation protection for radiation workers, the public, and the environment is of international concern. The use of thermoluminescence dosemeters (TLD) is an acceptable method for dose recording in most countries. For reasons of consistency and data gathering (research) it is important that a Sievert (Sv) in one part of the world equals an Sv on the other side of the globe. To this end, much work has gone into the development of standards and calibration practices for TLD systems so that they compare not only with similar systems, but also with other forms of radiation measurement. While most national laboratories provide calibration services for these systems some, as in the United States, depend on services of secondary calibration laboratories that are traceable to the national laboratories through accreditation programmes. The purpose of this paper is to explain how TLD measurements are traceable to their respective national standards for both personnel and environmental dosimetry.

The predominant way of thinking of these issues, at least in broader political discourse, assumes that obtaining work or improving wages are desirable goals for welfare recipients & their families. However, recent research has begun to suggest that single parents & their families are not always better off in the labor force. This paper uses the 1991 & 1992 panels of the Survey of Income & Program Participation to examine welfare, work, & well-being in a broader context. The paper finds an apparent advantage of work over welfare for most households, but not for single-parent households. In addition, material hardship is found to have strong effects on subsequent labor market participation & welfare use. 4 Tables, 35 References. Adapted from the source document.

Panels of households were randomly assigned to receive either 1990-style or 2000-style mail questionnaires to evaluate the effects of questionnaire design changes on responses to questions about race & Hispanic origin. The questionnaire changes included dropping examples from both questions. This note considers alternative hypotheses about how examples affect recall & comprehension, & compares experimental panels to assess the effects of examples on detailed Hispanic reporting. There were fewer write-in responses of detailed Hispanic groups & more write-ins of generic Hispanic identities ("Hispanic," "Latino," or "Spanish") in 2000-style questionnaires. This suggests that examples helped respondents understand the specificity of response that was intended by the question; other design differences probably also contributed to the difference in reporting. Some implications of the findings for use of examples in surveys & for comparisons of 1990 & 2000 census data are discussed. 3 Tables, 2 Figures, 11 References. Adapted from the source document.

At McCreedy West and Falconbridge, the isochron Re-Os ages are 1835+ or -70 Ma and 1827+ or -340 Ma, and the initial (super 187) Os/ (super 188) Os ratios 0.514+ or -0.019 and 0.550+ or -0.024, respectively. The ages agree with the canonical value of 1850+ or -1 Ma for the Sudbury Igneous Complex (SIC). For Hangingwall and Deep Zone ores at Strathcona, the age of 1780+ or -7 Ma may reflect resetting by dyke activity. The high initial (super 187) Os/ (super 188) Os of 0.934+ or -0.005 in these ores is distinct from those at McCreedy West and Falconbridge. Strathcona Deep Copper Zone ores have highly radiogenic Os giving a mean model age of 1883+ or -54 Ma that is similar to ages at McCreedy West and Falconbridge, but distinct from other Strathcona sulfides. Initial (super 186) Os/ (super 188) Os in two Strathcona ores with low (super 190) Pt/ (super 188) Os average 0.119 826+ or -0.000 009 (n = 3) and 0.119 827+ or -0.000 004 (n = 3), respectively, with a grand mean of 0.119 827+ or -0.000 003. This ratio may be slightly lower than the chondritic value at that time. Similar ores at Falconbridge and McCreedy West show more scatter, averaging 0.119 855+ or -0.000 008 (n = 6) and 0.119 867+ or -0.000 020 (n = 3), respectively. These values are substantially suprachondritic. The Re-Os isotope systematics of Sudbury ores are clearly of crustal origin and may be derived from a binary mixture of Superior Province and Huronian metasedimentary rocks, with Strathcona, Falconbridge, and McCreedy West ores containing, respectively, 55%, 16%, and 12% of Os from Superior sediments. The suprachondritic (super 186) Os/ (super 188) Os at McCreedy West and Falconbridge may be due to admixture of Archean or Paleozoic mafic rocks with (super 190) Pt/ (super 188) Os nearly equal 0.1. No trace of the asteroid that produced the Sudbury Structure has been reported. At the Whistle mine S-poor olivine melanorite inclusions with high Ni and Os and low (super 187) Os/ (super 188) Os may contain the signature of a magmatically fractionated asteroidal core contributing 1 to 2.5% metal. The S-poor melanorite Ni and Os data are equally well explained by admixture of nearly equal 40% mantle peridotite, however.

The monthly and annual net sea-air CO (sub 2) flux has been computed using the NCEP/NCAR 41-year mean monthly wind speeds. An annual net uptake flux of CO (sub 2) by the global oceans has been estimated to be 2.2 (+22% or -19%) Pg Cyr (super -1) using the (wind speed) (super 2) dependence of the CO (sub 2) gas transfer velocity of Wanninkhof (J. Geophys. Res. 97 (1992) 7373). The errors associated with the wind-speed variation have been estimated using one standard deviation (about + or -2 ms (super -1) ) from the mean monthly wind speed observed over each 4 degrees X5 degrees pixel area of the global oceans. The new global uptake flux obtained with the Wanninkhof (wind speed) (super 2) dependence is compared with those obtained previously using a smaller number of measurements, about 250,000 and 550,000, respectively, and are found to be consistent within + or -0.2 Pg C yr (super -1) . This estimate for the global ocean uptake flux is consistent with the values of 2.0+ or -0.6 Pg C yr (super -1) estimated on the basis of the observed changes in the atmospheric CO (sub 2) and oxygen concentrations during the 1990s (Nature 381 (1996) 218; Science 287 (2000) 2467). However, if the (wind speed) (super 3) dependence of Wanninkhof and McGillis (Res. Lett. 26 (1999) 1889) is used instead, the annual ocean uptake as well as the sensitivity to wind-speed variability is increased by about 70%. A zone between 40 degrees and 60 degrees latitudes in both the northern and southern hemispheres is found to be a major sink for atmospheric CO (sub 2) . In these areas, poleward-flowing warm waters meet and mix with the cold subpolar waters rich in nutrients. The pCO (sub 2) in the surface water is decreased by the cooling effect on warm waters and by the biological drawdown of pCO (sub 2) in subpolar waters. High wind speed over these low pCO (sub 2) uptake rate by the ocean waters. JF - Deep-Sea Research.

The bases for accuracy judgements are multi-year averages of crossover sea height differences from Geosat and ERS 1/2 missions. This radially sensitive data is fully independent of the data used to develop these gravity models. There is good agreement between the observed differences in all of the world's oceans and projections of the same errors from the scaled covariance matrix of their harmonic geopotential coefficients. It was found that the tentative scale factor of five for the formal standard deviations of the harmonic coefficients of the new GRIM fields is justified, i.e. the accuracy estimates, provided together with the GRIM geopotential coefficients, are realistic.

The resulting field can be evaluated outside or inside the sphere, assuming that density of the shell varies with latitude, longitude, and radial distance. To simplify, the density (or magnetization) source inside the sphere is assumed to be the product of a surface function and a power series expansion of the radial distance. This formalism is applied to compute the gravity signal of a steady, dry atmosphere. It provides geoid/gravity maps at sea level as well as satellite altitude. Results of this application agree closely with those of earlier studies, where the atmosphere contribution to the Earth's gravity field was determined using more time-consuming methods.

The method uses series expansions and the well known one-dimensional fast Fourier transform (1-D FFT) method. It has been proven to be significantly faster than quadrature while being equally accurate. Various quantities were studied to cover the two primary applications of the Stokes-Helmert scheme of modeling effects. These two applications (or paths), given the names R/r/D and R/D/r, are briefly discussed, although the primary objective of the paper is to provide computational information to either path, rather than choosing one path as preferable to the other. It is further shown that the impact of masses outside a 4-degree cap can impact the absolute computation of the geoid at more than 1 cm, and should therefore be included in all local geoid computations seeking that accuracy.

The pre-analysis measures are primarily based on familiar elements of the linear programming solution to L (sub 1) -norm minimization, such as slack variables and the reduced-cost vector. By examining certain elements of the linear programming solution in a probabilistic light, it is possible to derive the cumulative distribution function (CDF) associated with univariate L (sub 1) -norm residuals. Unlike traditional least squares (LS) residual CDFs, it is found that L (sub 1) -norm residual CDFs fail to follow the normal distribution in general, and instead are characterized by both discrete and continuous (i.e. piecewise) segments. It is also found that an L (sub 1) equivalent to LS redundancy numbers exists and that these L (sub 1) equivalents are a byproduct of the univariate L (sub 1) univariate residual CDF. Probing deeper into the linear programming solution, it is found that certain combinations of observations which are capable of tolerating large-magnitude gross errors can be predicted by comprehensively tabulating the signs of slack variables associated with the L (sub 1) residuals. The developed techniques are illustrated on a two-dimensional trilateration network.

This new bathymetry has resulted from long-term efforts by the NOAA (National Oceanic and Atmospheric Administration) U.S. Coast Survey, the NOAA National Geophysical Data Center, and by investigators at Texas A&M University and Louisiana State University. The bathymetry provides enhanced depiction of known features and inevitably results in discovery of previously unknown features. On the continental shelves (0-100 m), ridges, reefs, channels, and domes of no more than a few meters relief are being seen for the first time. On the Outer Continental Slope larger relief features emerge, including rounded basins and domes, ridges, canyons, escarpments, hills, mounds, other sediment depositional features, deltas, and fans. Imagery and bathymetric contours, which can only be described as spectacular, promote interpretations and provide a sense of what is to come. As continental shelf and slope features of the northern Gulf of Mexico become known, and the bathymetry is utilized (fishing, ocean engineering, habitat assessments, scientific investigations, environmental protection, hazards prediction), the need arises for new geographic names, as well as promulgation and standardization of these and existing names. A provisional gazetteer of names has been developed and is currently posted on the NOAA National Geophysical Data Center website.

The EAARL is a raster-scanning, water-penetrating, full-waveform adaptive lidar that is coupled to aircraft positioning systems and a downlooking color digital camera. The EAARL has unique capabilities for simultaneously mapping topography, shallow bathymetry, and vegetation. Initial analysis within 2 Tampa Bay subregions traversed by the survey flightlines has revealed that the EAARL can survey shallow bathymetry and variables associated with benthic cover in remarkable detail. The results of this ongoing study will aid in developing recommendations on the appropriate use of NASA EAARL surveys for mapping bathymetry and benthic habitats in estuaries around the Gulf of Mexico.

For a given mineral microstructure, thermal stresses and elastic strain energy varied with the single-crystal elastic constants and coefficients of thermal expansion. Moreover, they were a strong function of crystallographic texture. Given the same morphological microstructure and crystallographic texture, calcite had larger thermal stresses and elastic strain energy than dolomite. Hence, calcite has an earlier onset of microcracking upon either heating or cooling, and has a greater extent of microcracking at a given temperature differential. However, the variation in thermal stresses and microcracking propensity for either mineral with different randomly assigned textures was greater than the variations between the two minerals. The measured bulk thermal expansion anisotropy suggested that the random representations had some degree of texture. Simulations using the actual texture of the real microstructure, as determined by electron-backscattered diffraction, showed the largest degree of bulk thermal expansion anisotropy, the smallest strain energy, and hence the smallest amount of thermal microcracking. Microstructure-based finite element simulations are considered an excellent tool for elucidating myriad influences of microstructure and physical properties on the thermal degradation of marbles and other rocks.

These impacts can influence the levels of the Great Lakes and the volumes of channel flow among them, thus affecting their value for interests such as riparians, shippers, recreational boaters, and natural ecosystems. On one hand, a hydrological modeling suite using input data from the CGCM1 predicts large drops in lake levels, up to a maximum of 1.38 m on Lakes Michigan and Huron by 2090. This is due to a combination of a decrease in precipitation and an increase in air temperature that leads to an increase in evaporation. On the other hand, using input from HadCM2, rises in lake levels are predicted, up to a maximum of 0.35 m on Lakes Michigan and Huron by 2090, due to increased precipitation and a reduced increase in air temperature. An interest satisfaction model shows sharp decreases in the satisfaction of the interests of commercial navigation, recreational boating, riparians, and hydropower due to lake level decreases. Most interest satisfaction scores are also reduced by lake level increases. Drastic reductions in ice cover also result from the temperature increases such that under the CGCM1 predictions, most of Lake Erie has 96% of its winters ice-free by 2090. Assessment is also made of impacts on the groundwater-dependent region of Lansing, Michigan.

The effect of large scale resuspension on organic contaminant cycling was investigated using a two-pronged sample collection strategy that included analysis of settling sediment trap material and discrete air and water samples collected before and after a major resuspension event. It was found that major resuspension events result in a large flux of contaminants. For example, 6.2 ng/cm (super 2) Sigma PCB (sum of 89 congener peaks) and 175 ng/cm (super 2) Sigma PAHs (sum of 31 compounds) fell through the water column in the southern basin between November and May but almost half of that occurred in the month of March after a series of intense storms induced a large-scale resuspension event in that month. Assuming the concentration of contaminants in settling sediments is similar throughout the basin, the March event brought approximately 400 kg of Sigma PCBs and approximately 13,000 kg Sigma PAHs into the water column. Furthermore, the data indicate that concentrations of dissolved phase Sigma PCB and Sigma PAHs declined significantly (alpha = 0.05) after the event and after resuspended sediment had settled from the surface waters. As a result of the depressed dissolved concentrations at the surface, the potential for gas-phase input to the lake increases on the southwestern coastal region near Chicago, IL and Gary, IN. The potential input of gas-phase contaminants was 8 kg for Sigma PCBs and 2,200 kg for Sigma PAHs over the 40-day lifetime of the near-shore event.

The large scale of the plume implied that this process was important in sediment, and associated constituent, cycling and transport, but it had never been sampled due to severe conditions. The onset of the 1996 event coincided with a major March storm. Within a few days the plume was approximately 10 km wide and over 300 km in length, implying that the source of the reflective materials was widely distributed. An estimate of the total mass of resuspended sediment, 12 days after the storm, was similar to the annual external load of (sand-free) particulate material to the southern basin. The high turbidity plume persisted for over a month, progressing northward along the eastern shore with a major offshore transport feature. Sediment traps within this feature recorded a major mass flux event. The plume was sampled on two occasions and was found to contain 5 to 10 times as much suspended matter as open-lake locations outside the visible plume. Total particulate phosphorus was high within the plume making this episodic process important in sediment-water exchange. The diatom community structure within the plume was significantly different from outside the plume and was characteristic of more eutrophic waters. Abundance of non-diatom phytoplankton and microbial food web organisms were highest at the plume edge. The episodic nature of this process makes it difficult to sample, but the scale makes it important in designing monitoring programs and mass-balance modeling efforts.

The approach was to survey as many reefs in the area as possible that had at least some live cover of A. palmate, the apparently preferred prey but least abundant of the two coral hosts. Snail abundance patterns were examined with regard to the population characteristics of their host corals such as colony size and condition. With the naming of Acropora palmate to the Candidate Species list in 1999, the survey gained a bit more focus on the status of the A. palmate colonies, themselves.

Fragmentation among institutions, international agencies, and disciplines, lack of cooperation among nations sharing marine ecosystems, and weak national policies, legislation, and enforcement all contribute to the need for a new imperative for adopting ecosystem-based approaches to managing human activities in these systems in order to avoid serious social and economic disruption. The global environment facility (GEF) has been approached by developing countries in overwhelming numbers for assistance in securing the futures of their shared large marine ecosystems (LMEs). This paper describes GEF supported processes being used to assist them in adopting a science-driven, ecosystem-based approach to the management of human activities affecting coastal and marine ecosystems and linked freshwater basins. At risk are renewable goods and services valued at $10.6 trillion per year. A total of 10 LME projects involving 72 countries have been approved by the GEF Council, and another 7 LMEs involving 54 countries have GEF international waters projects under preparation. A five-module assessment and management methodology is being tested that moves the countries toward adopting practical joint governance institutions through place-based management. This LME approach engages stakeholders, fosters the participation of the science community, and leads to the development of adaptive management institutions. Comprehensive initiatives in four LMEs are described. The importance is underscored for establishing and coordinating partnerships between the North and South for specific LMEs and their linked watersheds. These coordinated North-South partnerships significantly augment catalytic interventions made by the GEF leading to reforms and investments that are helping make the transition to sustainable development.

Certain species of phytoplankton from the genus Pseudo-nitzschia, and the genus Alexandrium are concentrated by filter-feeding shellfish and finfish which when consumed by humans, marine mammals, or birds can result in ASP and PSP, respectively. Specifically in the subtropical region of Hawaii, ciguatera fish poisoning (CFP) is also known to be a problem, caused a nerve poison, ciguatoxin, produced by the dinoflagellate, Gambierdiscus toxicus. Other harmful species, including the raphidophyte, Heterosigma akashiwo, and the diatoms from the genus Chaetoceros, kill fish at aquaculture sites, but are not known to be harmful to humans. Water discolorations (red tides) caused by noxious phytoplankton, such as Noctiluca scintillans and Ceratiun spp., also occur throughout the area and are noted to be nuisance species but are not included in this summary. This report will focus on those algae that produce toxins known to be harmful to humans.

The History of Marine Animal Populations project, part of the Census of Marine Life, undertook to develop historical catch estimates for humpback whales in this region. This was done in collaboration with the International Whaling Commission's Scientific Committee's reconstruction of humpback whale populations in this region. Catch series for the 20th century were produced using reports by the industry, some on a whale-by-whale basis and others in aggregate form. Catch series for earlier periods required the use of colonial trade records, voyage logbooks and published lists of whaling voyages. Approximately 30 distinct fisheries were estimated to have removed more than 24,000 humpback whales since 1800 from all known breeding and feeding grounds in the North Atlantic. Removals peaked between about 1850 and 1920 in the tropical breeding grounds and between about 1880 and 1920 in the northern feeding grounds. A complex spatial model with density dependence on feeding ground abundances was used to integrate removal data with information on population breeding structure, regional abundance, and estimated rates of increase in different feeding grounds. The model estimated the time series of abundance levels that was inconsistent with the observed higher rates of increase of this species in most areas of the North Atlantic. The implications of this lack of fit are described, especially the suggestion that there has been a significant ecosystem change over the 20th century, and compared this work with earlier similar attempts at historical modelling of California gray whales and Beaufort Sea bowhead whales.

In recognition of the problem, the Global Environment Facility (GEF) has been approached by developing countries for assistance in planning and implementing projects for assessing and managing resources and environments of Large Marine Ecosystems (LMEs) in Africa, Asia, Latin America, and Eastern Europe. Seventeen LME projects involving 126 countries have been approved or are in preparation for funding support by the GEF Council. The participating countries are putting in place an ecosystem-based, five-module methodology based in systematic assessments of LME productivity, fish and fisheries, pollution and ecosystem health, socioeconomics, and governance. The GEF Operational Strategy recommends that nations sharing an LME begin to address coastal and marine issues by jointly undertaking strategic processes for analysing scientific information on transboundary concerns, their root causes, and setting priorities for action on transboundary concerns. The national interministerial committee established in each country to operationalize reforms and programs is particularly important to achieve practical integration of needed actions in different economic sectors. However, the GEF was designed to play a minor, catalytic role and new North-South partnerships in LME monitoring and assessment is needed to sustain the $200 million in GEF/LME project momentum that has been created.

We classified sea otter habitat as rocky, sandy, or mixed during aerial surveys along the Washington coast in March 2000. We characterized substrate type and kelp composition from the coast to the 40-m depth contour and computed area (km super(3)) and available coastline (km) within each habitat. We calculated maximum foraging depths and maximum distance from shore for 68 sea otters radiotagged between 1994 and 1998 and used the estimates to approximate the offshore extent of sea otter habitat. We used the most current population survey data (1996-1999) to obtain equilibrium densities of sea otters in rocky habitat in Washington. Because sea otters have only recently occupied sandy or mixed sites, the equilibrium densities for these habitats represent a proportional density based on current counts in the rocky equilibrium region in Washington and available data from the California sea otter population. Index estimates of K for the Washington sea otter population range from 1,372 (CV 0.13) to 2,734 (CV 0.13). These estimates are useful for sea otter management because they directly relate to the index counts used to monitor the population since 1977. Our results will facilitate decision-making by entrusted management agencies regarding stock assessment and population status under the United States Marine Mammal Protection Act.

Our monitoring in 1997 showed that coastal upwelling was initiated in April, the usual time. However, a series of southwesterly storms in May and June 1997 led to a prolonged warming event and reductions in copepod biomass. Though el Nino-driven atmospheric teleconnections might have been responsible for these storms, the coastal ecosystem returned to normal with the resumption of coastal upwelling in mid-July 1997. A downwelling event began on 20 August 1997 resulting in onshore movement of offshore waters. This event appeared to mark the passage of the first Kelvin wave. At this time the shelf became flooded with low-nutrient waters and offshore, 'warm-water' copepod species were transported shoreward. The abundance of local endemic boreal neritic copepod species was reduced greatly, presumably because they were transported out of the system and to the north as a result of the strong poleward flows. Poleward flows strengthened during autumn, and the ocean off Oregon remained anomalously warm through the winter of 1997, spring, and early summer of 1998. Species composition of the coastal copepod assemblage remained anomalous for about a year; species with offshore and subtropical affinities dominated from late August 1997 through late July 1998. During this same period, nitrate concentrations were reduced by a factor of 4.5 (11-month mean of 1.5 mu M for August 1997-July 1998 versus 6.9 mu M for August 1998-July 1999), copepod biomass was reduced by a factor of 2.1 (4.9 mu g carbon l super(-1) versus 10.5 for the same time periods), but chlorophyll concentrations were similar (2.0 versus 2.5 mu g l super(-1)). Perhaps the most dramatic effect on copepods during the el Nino period was the nearly complete disappearance of the normally dominant boreal neritic copepod species (Pseudocalanus mimus, Calanus marshallae and Acartia longiremis) and their replacement by subtropical species such as Calanus pacificus, Paracalanus parvus, Ctenocalanus vanus, Corycaeus anglicus and several species of Clausocalanus. These species persisted in the coastal waters through the end of 1998. Although most of the subarctic species began to increase in numbers in August 1998, the impact of the el Nino on Pseudocalanus mimus, normally the numerical dominant in coastal waters, was longer lasting. The P. mimus population did not recover to normal abundance levels until summer of 1999.

Annually, NCEPRII shows 0.7 mm d super(-1) of atmospheric moisture converged into the land region with a corresponding runoff of 0.7 mm d super(-1) to the Baltic Sea, consistent with observations. However, precipitation is too low; evaporation is too large; runoff does not have an appropriate winter minimum and spring maximum; the assimilation and surface nudging are too large. Important hydroclimatic characteristics can still be discerned. During summer, atmospheric water vapor, precipitation, evaporation, and surface and atmospheric radiative heating increase and the atmospheric radiative cooling, dry static energy convergence decrease. There are large contrasts between the sea and land; during winter sensible heat is transferred from the sea to the atmosphere and sea evaporation and precipitation are largest during the fall and winter; somewhat opposite behavior occurs over land.

Of these three, the seasonal water level fluctuations have received relatively little attention. The Great Lakes water levels have a well defined seasonal cycle driven primarily by snowmelt in the spring and summer and lake evaporation in the fall and winter. The present average seasonal cycle ranges from 26 cm on Lake Superior to 38 cm on Lake Ontario. Great Lakes monthly water levels from 1860 to 2000 were used to assess changes in the seasonal cycle of each of the Great Lakes and Lake St. Clair over the past 140 years. Changes are found on all of the lakes during the period of record. They usually resulted in a decrease in seasonal range and a time shift in the months of seasonal maximum and minimum. The effects of lake regulation were found to be negligible in the case of Lake Superior and significant for Lake Ontario. The major changes on Lakes St. Clair and Erie are likely a result of changes in the connecting channels ice retardation rather than changes in seasonal hydrometerology. Seasonal cycle regimes are delineated for each of the lakes and possible rationale for the changes discussed.

It became the major suspension feeder replacing cladocerans (Mac Isaac et al. 1992). They estimated that these mussels could filter large volumes of western Lake Erie daily and calculated that settled mussels could filter the western basin to a depth of 7 m 3.5 to 18.8 times daily. The mussels established large populations on reefs and they are now found on sandy and silt sediments (Mac Isaac et al. 1992). This paper is the third in a series based on sampling, almost weekly, year round, in Hatchery Bay of South Bass Island in western Lake Erie. The paper by Holland (1993), based on extensive pre- and post-zebra mussel diatom data, showed that water clarity increased 100% and diatom numbers were reduced by 86% after zebra mussels became established. Analyses of water samples for major nutrients showed that concentrations of soluble reactive phosphorus, ammonia, nitrate, silica and chloride increased after establishment of Dreissena. Consequently, two symptoms of eutrophication, decreased water clarity and increased algae, were lessened, but the increases in nutrients show the system is not more oligotrophic. The very efficient filtering of phytoplankton by Dreissena may preclude full utilization of the nutrients. This situation can be called biological olieotrophy (Holland et al. 1995).

Information concerning toxin variability relative to sampling location is important in developing a more reliable plan for managing DA outbreaks. In November 1998 record levels of razor clams (up to 295 ppm) were reported at Kalaloch beach, Washington. A razor clam resource survey conducted there during the summer of 1999, along with the long retention time of DA in the clams, permitted a study of DA levels as a function of tidal elevation and north-south beach location. During the summer low tides (28-31 July 1999) razor clams were collected from six east-west transects, approximately 1.6 km apart. Each clam was individually analyzed for DA to determine the distribution of toxin between (interspecific variability) and within (intraspecific variability) transects. While average DA levels were similar between transects, toxin levels varied substantially among individual clams. The coefficient of variation among all samples (n=445) was 122%, indicating that harvest closures based upon composite analyses of only six clams could be in error. A sampling strategy of razor clams for regulatory purposes is recommended, that will result in DA measurements more representative of total population toxin values.

Studies of short-term behavioural responses to underwater noise associated with aircraft, ships and seismic explorations indicate a 0.5 probability that whales will respond to continuous broadband noise when sound levels exceed ca 120dB super(2) and to intermittent noise when levels exceed ca 170dB, usually by changing their swimming course to avoid the source. Gray whales were 'startled' at the sudden onset of noise during playback studies, but demonstrated a flexibility in swimming and calling behaviour that may allow them to circumvent increased noise levels. Whales may be 'harassed' by noise from large commercial vessels, especially in shipping lanes or near busy ports. Gray whales sometimes change course and alter their swimming speed and respiratory patterns when followed by whalewatching boats. Conversely, some whales swim toward small skiffs deployed from whalewatching boats in breeding lagoons, seemingly attracted by the noise of idling outboard engines. Reported gray whale reactions to aircraft are varied and seem related to ongoing whale behaviour and aircraft altitude. Whale response to research involving tagging and biopsy sampling appears to be short term. Gray whales were seen swimming through surface oil from the Exxon Valdez oil spill along the Alaskan coast and showed only partial avoidance to natural oil seeps off the California coast. Laboratory tests suggest that gray whale baleen, and possibly skin, may be resistant to damage by oil, but spilled oil or oil dispersant in a primary feeding area could negatively affect gray whales by contaminating benthic prey. Gray whales are sometimes injured or killed in collisions with vessels or entanglement in fishing gear. Concern about the cumulative long-term impact of offshore human activities is particularly acute in the Southern California Bight, where many activities are often concurrent.

AN - 18764697; 5633461 AB - There has been a marked increase government funding for the U.S. Caribbean over the last 2 years. This has resulted in vastly improved regional mapping, monitoring, and management of coral reef ecosystems of Florida, Texas, Puerto Rico, U.S. Virgin Islands and Navassa. These improvements have resulted in significant advances in our understanding of the condition and functioning of these coral reefs. Digital maps of the US. Caribbean, including photo-mosaics, individual aerial photographs, classified habitat maps, a mapping ArcView extension classification scheme, and methods manual, were completed and are available on CD-ROM and the web (www.biogeo.nos.noaa.gov). Maps of benthic habitats of the Florida Keys National Marine Sanctuary (FKNMS) were completed in 1998 and are also available. The NOAA (National Oceanic and Atmospheric Administration) National Coral Reef Monitoring Program has been expanded from US$0.6 to 0.9 million and now supports monitoring of water quality, reef fish populations, and the habitat in Florida as well as in Puerto Rico and the U.S. Virgin Islands. A comprehensive monitoring program in the FKNMS was expanded, and shows that fishes in no-take reserves are larger and more abundant than in fished reference areas. Databases have been improved to allow easier data entry from the field and many are now available on-line. Monitoring data are published in peer-reviewed literature and in the first National Report on the Status and Health of U.S. Coral Reef Ecosystems. JF - Status of coral reefs of the World: 2002.

Recent molecular comparisons confirm, based on differences in haplotypic frequencies, that these populations are genetically separated at the population-level. Both populations were commercially hunted, but only the eastern gray whale has returned to near pre-exploitation numbers. In contrast, the western population remains highly depleted, shows no apparent signs of recovery and its future survival remains uncertain. Research off Sakhalin Island, Russia between 1995 and 1999 has produced important new information on the present day conservation status of western gray whales and provided the basis for the World Conservation Union (IUCN) to list the population as 'Critically Endangered' in 2000. The information presented here, in combination with potential impacts from anthropogenic threats throughout the range of this population, raises strong concerns about the recovery and continued survival of the western gray whale.

AN - 18760939; 5633460 AB - Coral reefs in the Hawaiian Archipelago stretch over 2,000km and comprise over 80% of U.S. coral reefs. The Main Hawaiian Islands (MHI) are populated, high, volcanic islands with non-structural reef communities and fringing reefs abutting the shore, and the Northwestern Hawaiian Islands (NWHI) with mostly uninhabited atolls and banks containing most (65%) of US reefs. There are major differences in anthropogenic impacts: the MHI have extensive urban developments and associated runoff; over-fishing for food and marine ornamentals; invasions by alien species; and accumulation of marine debris. The NWHI coral reefs suffer minor damage from marine debris and the impacts from lobster and bottom fisheries, but concerns exist over current and proposed ecotourism activities and new fisheries. Increased U.S. Federal funding in 2001 and 2002 supported mapping, monitoring, research, and management initiatives. Digital habitat maps were completed for 60% of the MHI and will be available in January 2003. The Hawaii Coral Reef Institute received over US$l million in 2002 for coral reef research and monitoring to assist in the management of Hawaii's coral reefs. There have been surveys for the spread and control of invasive algae, assessments of the impact of stepping or anchoring on corals, and monitoring of water quality and the harvest of aquarium fish on reefs in the NWHI. The National Coral Reef Monitoring program developed on-line databases for field data entry and tracking research progress. Monitoring data were published in the first National Report on the Status and Health of US Coral Reef Ecosystems. Capacity in Hawaii to manage coral reefs and fisheries was expanded, and an economic evaluation of coral reefs completed in 2002. An Environmental Characterization of the Ahupua'a of Waianae, Hawaii, assembled information on terrestrial and marine resources, land-use patterns, traditional Hawaiian land and resource management concepts, and land cover data to identify potential stresses to coral reefs and how to mitigate them. The Northwestern Hawaiian Islands Coral Reef Ecosystem Reserve was established to conserve the coral reefs and related marine resources. Progress is encouraging on: sanctuary designation and operations; research, mapping and monitoring; and marine debris removal. Draft benthic habitat maps were completed for 9 of 10 areas and bathymetry determined for all areas. A detailed atlas of the NWHI, will be available in January 2003.

To determine how much gene flow among brood years is occurring, we evaluated temporal differences in allozyme allele frequencies in four coho salmon populations in Washington State. Forty-three loci were polymorphic in the 26 samples, totaling 2,328 fish, that were collected from three naturally spawning populations and one hatchery population over 7 years. Our results indicate a greater degree of geographic variation among populations than temporal variation within populations, suggesting that population genetic analyses that depend on spatial variation can be done on natural coho salmon populations even in the absence of temporal sampling. Using a modification of the temporal method for estimating effective population size, we estimated the effective proportion of 2-year-olds to be 35% for each of the naturally spawning populations and 2% for the hatchery population. These results suggest that precocity is a viable and important life history strategy in the naturally spawning coho salmon populations we studied.

In the absence of oil, 2-year-old juvenile red king crabs preferred a bryozoan-hydroid assemblage or cobble over shale, shell hash, sand, or mud. Sand was chosen <3% of the time and mud was never selected. Juvenile Tanner crabs selected bryozoan-hydroid assemblages or buried in either sand or mud and avoided the larger-grain substrates. In oil experiments using three sediment types (mud, sand, cobble), grain size was often more important in sediment selection than the presence or absence of contaminants. If the preferred sediment type was oiled and the alternative sediment was unoiled but of smaller grain size, both species selected the preferred sediment. Red king crabs avoided sediments containing 500-800 mu g per g total hydrocarbons if unoiled sediment of the same or larger grain size was available. Addition of oil to the unpreferred sediment increased selection of preferred sediment. In contrast, the Tanner crabs selected fine-grained sediments whether oil was present or not. The lack of avoidance by crabs at concentrations <500 mu g per g may lead to long-term exposure to contaminated sediment in areas where benthic sediments are chronically polluted. JF - 19.

Comparisons were made between data from an OPC-2T towed in Lake Michigan and concurrent plankton net collections. Polystyrene spheres, nylon rods, or live zooplankton were circulated through an OPC-1L and OPC-2T during laboratory tests. An OPC can accurately count and size spherical particles, but may overestimate the mass of elongated particles such as zooplankton. The OPC measures the area of an animal's silhouette and converts it to an equivalent circular diameter (ECD) that is used as a spherical diameter to calculate volume and mass. To obtain the best biomass estimates, a correction factor based on the average shape of the zooplankton must be applied to ECDs. In the field, OPC results can be affected by many factors, including the shape of an animal and its orientation when passing through the OPC, zooplankton concentration, and other particles in the water. Since various environmental factors can also affect net sampling, correlations between plankton net and OPC data can be quite variable spatially and temporally. The OPC is best used to gather zooplankton abundance, biomass, and size frequency data on large spatial scales, supplementing plankton net data, not replacing it.

Declines were first observed in 1992 and the area with few or no amphipods has become more extensive each year. Between 2000 and 2001, Diporeia populations continued to decline along the eastern side of the southern basin, but have stabilized or increased along the western side. On the east side, few Diporeia are found to depths of 70 m as far north as Grand Haven. Just 20 km farther north at a 45-m site near Muskegon, Diporeia is still present, but numbers fluctuate from year-to-year. On the west side, Diporeia is gone from areas to depths of 70 m south of Waukegan, but is still very abundant farther north. At the 45-m site off Muskegon, densities were 10,000 m super(-2) in 1997 and declined to less than 100 m super(-2) in fall 2000. In spring 2001, reproduction occurred and numbers increased. Growth and survivorship was normal until fall when numbers abruptly declined. Lipid content of these individuals increased from 25% of dry weight in spring to 38% in late summer, and then decreased back to 25% in fall. Other measures of physiological health such as length-weight, ETS, and C:N ratios will be presented and discussed.

In Lake Michigan Cercopagis first occurred in 1999 and attained high densities in 2000 and 2001 in the nearshore zone. Regular sampling was done in 2000 and 2001 at three stations of depths 15, 45 and 110 m close to Muskegon, and at one station on Muskegon Lake, a drowned river mouth, to get a basic set of abundance and population data on Cercopagis in its new environment. Cercopagis was found between early July and early October. Early in the start of the season it occurred at all stations, with higher concentration at nearshore; later it was limited to the nearshore zone. The population consisted mostly of parthenogenetic females of the second instar over all seasons; third instar animals were present in higher percentage only in the beginning of the season. Clutch size varied temporally and spatially: it was higher at the end of July and August and was slightly higher at the 45-m deep than at the 15-m deep station.

The system has proven effective in providing valuable survey information before, during and after sediment re-suspension events in Lake Michigan in support of GLERL's NOAA/NSF funded Episodic Events Great Lakes Experiment (EEGLE) program. The PSS is a towed multi-sensor platform capable of measuring turbidity, chlorophyll a, photosynthetically active radiation (PAR), conductivity, temperature, and zooplankton spatial distributions. All sensors are integrated using a serial data interface. All data are geo-referenced and registered with time, depth, and vehicle pitch, roll, and speed information. A deck unit supplies power for the underwater vehicle components and provides interfaces for data collection and system monitoring. System software provides real-time display of all marine environmental measurements and vehicle status.

Lake Michigan AN - 18658714; 5560055 AB - Ceropagis pengoi is a recent Ponto-Caspian invader to Lake Michigan that was first found in 1999. In 2000, this predacious cladoceran was collected off Muskegon, MI. Seasonal data reveal that the highest C. pengoi densities occurred in August at 2500 per m super(2) at a 15-m-deep site. At 45-m-deep site further offshore, the highest densities also occurred in August at 800 per m super(2), and at a 110-m-deep site even further offshore C. pengoi densities were negligible. Seasonal distributions of another non-native species of predacious zooplankton, Bythotrephes cederstroemii, were near completely opposite of those for C. pengoii. B. cederstroemii were most abundant at the 110-m offshore site and at the 15 and 45-m-deep sites B. cederstroemii densities increased in the fall when C. pengoi densities were negligible. During the last three years, shifts have occurred in the densities of native zooplankton communities in S.E. Lake Michigan. Fish predation may be responsible for these shifts. However, predation in the nearshore by C. pengoi and in the offshore by B. cederstroemii may also contribute to changes in the native zooplankton community.

To identify obstacles to migration, we documented the movements of radio-tagged adult Pacific lampreys in specific areas of fishways (entrances, collection channels, transition areas, ladders, and counting stations) at the first three dams they encounter as they move upstream (Bonneville, The Dalles, and John Day). From 1997 to 2000, 147-299 radio-tagged lampreys were released downstream from Bonneville Dam. In 1997 and 2000, we also moved 50 radio-tagged lampreys each year to positions upstream from Bonneville Dam to assess the passage success of fish that had not passed through an entire fishway (i.e., "naive fish"). The passage efficiency of lampreys at Bonneville Dam was 38-47%, and the median time required to pass over the dam ranged from 4.4 to 5.7 d. In contrast, 50-82% of the lampreys passed over The Dalles Dam in each year, and passage times ranged from 2.0 to 4.0 d. Passage efficiency was lowest at John Day Dam, but that estimate was based on relatively few fish. After entering the fishways, lampreys had the greatest difficulty (1) negotiating collection channels and transition areas that lacked attachment sites and (2) passing through the Bonneville Dam counting stations. Unexpectedly high passage success was documented in the ladders, where maximum current velocities could exceed 2.4 m/s. We found no evidence that lampreys released downstream from Bonneville Dam had higher passage success at The Dalles Dam than naive fish. In each year up to 60% of the lampreys made multiple entrances at the fishways, indicating that lampreys persistently attempted to pass upstream. Dams in the lower Columbia River impede adult Pacific lamprey migration, and only 3% of the fish we tagged reached areas above John Day Dam.

Eight years of collocated data from five NTN and Atmospheric Integrated Research and Monitoring Network (AIRMoN) sites are compared here. Unlike previous analyses, the data from these two data sets were analyzed in the same laboratory using the same analytical methods; therefore, factors that influence concentration differences can be isolated to sampling frequency and sample preservation techniques. For comparison, the relative biases for these data have been calculated using both median value and volume-weighted mean concentrations, following two different approaches in the literature. The results suggest a relative bias of about 10% in [NH sub(4) super(+)] (NTN less than AIRMoN), which is smaller than previous estimates that included the influence of inter-laboratory comparisons. The annual relative bias of [H super(+)] increases over the analysis period, which results in a larger total relative bias for [H super(+)] than found in a previous analysis of AIRMoN and NTN data. When comparing NTN and AIRMoN data on monthly time scales, strong seasonal variations are evident in the relative bias for [H super(+)], [NH sub(4) super(+)], and [SO sub(4) super(2-)]. Large biases in [SO sub(4) super(2-)] (NTN greater than AIRMoN) on monthly times scales have not been detected in previous analyses where data for all seasons were considered together.

CPC powder is mixed with PLGA microspheres and water to yield a workable paste that could be sculpted to fit the contours of a wound. The cement then hardens into a matrix of hydroxyapatite microcrystals containing PLGA microspheres. The rationale for this design is that the microspheres will initially stabilize the graft but can then degrade to leave behind macropores for colonization by osteoblasts. The CPC matrix could then be resorbed and replaced with new bone. In the present study, osteoblast-like cells (MC3T3-E1 cells) were seeded onto graft specimens and evaluated with fluorescence microscopy, environmental scanning electron microscopy and the Wst-1 assay (an enzymatic assay for mitochondrial dehydrogenase activity). Cells were able to adhere, attain a normal morphology, proliferate and remain viable when cultured on the new composite graft (CPC-PLGA) or on a control graft (CPC alone). These results suggest that our new cement consisting of CPC and PLGA microspheres is biocompatible. This is the first time that a 'polymer-in-mineral' (PLGA microspheres dispersed in a CPC matrix) cement has been formulated that is moldable, resorbable and that can form macropores after the cement has set.

Examination of studies of salmonids reveals that such a relationship varies both among and within species. A correlation between genetic variability and fitness can be affected by genetic background, environment, and age, and it also depends upon the genetic markers and phenotypes evaluated. The relationships between molecular genetic variation, quantitative genetic variation, and phenotypic variation may be more relevant to conservation issues than those between genetic variation and average fitness or performance. Consequently, future work in salmonids should include more intensive investigation of the correspondence of molecular genetic variation within and among populations to quantitative genetic and phenotypic variation for traits affecting fitness. In the absence of a more complete understanding of the relationship between genetic variation and fitness, maintenance of genetic and phenotypic variation within and among conspecific populations should be considered a primary goal of conserving salmonid fishes.

AN - 18510958; 5468963 AB - Between 1985 and 2000, similar to 70% of new species that invaded the North American Great Lakes were endemic to the Ponto-Caspian (Caspian, Azov, and Black seas) basins of eastern Europe. Sixteen Ponto-Caspian species were also established in the Baltic Sea as of 2000. Many Ponto-Caspian endemic species are characterized by wide environmental tolerances and high phenotypic variability. Ponto-Caspian fauna evolved over millions of years in a series of large lakes and seas with widely varying salinities and water levels and alternating periods of isolation and open connections between the Caspian Sea and Black Sea depressions and between these basins and the Mediterranean Basin and the World Ocean. These conditions probably resulted in selection of ponto-Caspian endemic species for the broad environmental tolerances and eurhalinity many exhibit. Both the Baltic Sea and the Great Lakes are geologically young and present much lower levels of endemism. The high tolerance of Ponto-Caspian fauna to varying environmental conditions, their ability to survive exposure to a range of salinities, and the similarity in environmental conditions available in the Baltic Sea and Great Lakes probably contribute to the invasion success of these species. Human activities have dramatically increased the opportunities for transport and introduction and have played a catalytic role.

AN - 18509415; 5468967 AB - Dispersal and ecosystem impacts of six Ponto-Caspian endemic species that recently invaded the Great Lakes via ballast water are described, explained and "predicted". The zebra mussel, Dreissena polymorpha, and quagga mussel, Dreissena bugensis, continue to colonize hard and soft substrates of the Great Lakes and are changing ecosystem function through mechanisms of ecosystem engineering (increased water clarity and reef building), fouling native mussels, high particle filtration rate with selective rejection of colonial cyanobacteria in pseudofeces, alteration of nutrient ratios, and facilitation of the rapid spread of their Ponto-Caspian associates, the benthic amphipod Echiongammarus ischnus and the round goby, Neogobius melanostomus, which feeds on zebra mussels. The tubenose goby, Proterorhinus marmoratus, which does not feed on zebra mussels, has not spread rapidly. Impacts of these benthic invaders vary with site: in some shallow areas, habitat changes and the Dreissena - round goby - piscivore food chain have improved conditions for certain native game fishes and waterfowl; in offshore waters, Dreissena is competing for settling algae with the native amphipod Diporeia spp., which are disappearing to the detriment of the native deep-water fish community. The predatory cladoceran Cercopagis pengoi may compete with small fishes for zooplankton and increase food-chain length.

The relative abundance of cunner recruits was tracked over 1 reproductive season via visual counts on line transects across similar habitats at 4 sites across 3 boulder reefs in the vicinity of the Pilgrim Nuclear Power Station (PNPS) in Plymouth, Massachusetts, USA. Habitat characteristics including macroalgae structure, canopy height, rugosity (a measure of structure complexity), temperature, and visibility were measured at each site to assess the influence of these factors on recruit abundance. We assumed that immigration and emigration were not responsible for recruit abundance patterns through time due to the sedentary life history of cunner recruits. We observed differences in recruit abundance over the settlement period among reefs which were likely the result of differences in settlement. However recruitment at the end of the post-settlement period was similar across reefs. Recruit mortality rates among reefs differed in the post-settlement period, with the reef that had the highest density also having the highest mortality rate. Post-settlement mortality rates provided evidence for density-dependent mortality, since habitat and abiotic factors failed to explain the difference in mortality among reefs. Consequently, because of the existence of density-dependent processes in the post-settlement stages, entrainment mortality of the pre-settlement egg and larval stages by the PNPS will have a diminished effect on the local cunner population. An additional assessment of within-reef variability in recruitment also suggests recruitment success is sensitive to small changes in habitat structure which can occur over the recruitment season.

The ocean-effect snowstorm of 14 January 1999 AN - 18373933; 5365777 AB - On 14 January 1999, a very unusual snowstorm occurred across eastern Massachusetts. It was not associated with synoptic-scale low pressure, or even a frontal boundary, yet up to a foot fell across many of the southern suburbs of Boston. This was an ocean-effect snowstorm, with some equally intriguing snow enhancement mechanisms added to make it unusually prolific. Ocean effect can be considered a close cousin to lake-effect snow. Ocean-effect snow can form when a cold continental polar air mass moves offshore. The associated sensible heat and moisture flux from the ocean surface results in considerable boundary layer instability as the cold air moves over the relatively warmer waters. Similar to lake effect, a subsidence inversion associated with the continental polar air mass limits the depth of the convective boundary layer. Along the shoreline, differential diabatic heating induces frontogenesis, while shore-parallel surface winds result in frictional convergence. This convergence and frontogenesis enhances and helps organize the convective activity in the unstable boundary layer, which is typically in the form of horizontal rolls. Capes and peninsulas that jut out into the water body can also enhance convergence and thereby produce a locally stronger band.

Unfortunately, many studies pay little attention to the effects of model selection on the evolutionary inferences drawn from such correlative data. In this study, I employed a candidate model analysis to examine four potential causes of life-history evolution in the livebearing fish Brachyrhaphis rhabdophora. Combining factor analysis with path analysis, I constructed a nested set of 17 models that represent the hypothetical effects of four putative selective agents (mortality, density, resource availability, and habitat stability) on life-history evolution in this species. These models represent both direct and indirect effects of selection on the life history. Using the Akaike Information Criterion to distinguish among models, I found that simple models that contained only single selective agents most parsimoniously explained life-history divergence among 27 B. rhabdophora populations. Surprisingly, the four putative selective agents could not be distinguished, suggesting that the selective environment could be composed of a single selective agent confounded with other environmental factors, or could be composed of a suite of environmental factors that act in concert to shape the life history. In addition, comparisons among more complex models indicated that direct effects of selective agents appear to have primacy over combinations of indirect selective interactions in explaining intraspecific variation in B. rhabdophora life histories.

PAH metabolite levels in the bile of fish from mildly polluted stations were 7 to 10 times greater than those from reference stations. PAH metabolite levels in fish from a moderately polluted station and a highly polluted station were, respectively, 20 and 50 times greater than those from reference stations. Differential patterns of five major PAH metabolites in fish from the same station suggested individual variability in metabolic pathways possibly further convoluted by the differential inductions or suppressions of hepatic mixed-function oxygenase isozyme systems under various natural or anthropogenic habitat parameters. PAH metabolite levels in the bile of oyster toadfish correlated well with the gradient of PAH contamination in the Elizabeth River sediments. High levels of biliary PAH metabolites were not detected in muskrats (Ondatra zibethicus) collected along the polluted sections of the Elizabeth River, probably due to their primarily herbivorous nature. Assuming that the hepatobiliary system and the gastrointestinal tract are the major routes of biotransformation and excretion of PAHs in the muskrats, the contaminated diet appears to be a more important routes of exposure of muskrats (and possibly oyster toadfish) to PAHs than the transdermal transfer. Occurrence permitting, we propose oyster toadfish as a useful biological sentinel for early detection of estuarine PAH pollution.

This long-lived compound enters the surface ocean by air-sea gas exchange and is potentially a very useful transient tracer for studying ocean circulation and mixing. SF sub(6) has also been directly injected into the ocean at a minimal number of locations as a part of deliberate tracer release experiments to study gas exchange and sub-surface mixing rates. In this study, laboratory measurements of the solubility of SF sub(6) in water and seawater were made over the temperature range of similar to -0.5 degree C to 40 degree C. Volumes of water and seawater held at constant temperature in glass chambers were equilibrated with a gas mixture containing SF sub(6) and CFC-12 (CF sub(2)Cl sub(2)) at parts-per-trillion levels in nitrogen. Small volume water samples were analyzed by electron capture gas chromatography. Using the method of least squares, equations previously used in describing gas solubility as a function of temperature and salinity were fit to the SF sub(6) and CFC-12 measurements. The CFC-12 results were in good agreement with previous work, while substantial differences were found between these SF sub(6) results and those reported in earlier studies. The mean error for the analytical measurements is estimated to be similar to 0.5%. Based on errors in the fits and the analytical errors, we estimate the overall accuracy of the SF sub(6) solubility function to be of the order of 2%. The results from this work should be useful in determining equilibrium concentrations for SF sub(6) in ocean observation and modeling studies.

In addition, comparisons are made using the ceiling jet algorithm in CFAST (Version 3.1). The experiments include ceiling heights of 0.58 m to 22 m and heat release rates (HRR) of 0.62 kW to 33 MW. With the combined uncertainty of the measurement and the calculation roughly equal to plus or minus 20%, the algorithms of Evans and Davis consistently provided predictions either close to or within this uncertainty interval for all fire sizes and ceiling heights while the ceiling jet algorithm in CFAST consistently over-predicted the temperature.

The Kaizen business strategy involves everyone in an organization working together to make incremental improvements without large capital investment. Unlike many business improvement strategies practiced in the United States, which require radical change, Kaizen is an evolutionary approach. Kaizen is a culture of sustained continual improvement that focuses on eliminating waste in all systems and processes of an organization. Kaizen can only succeed with constant attention to people and their contributions to organizational improvement. Leadership is asked to guide--not direct--the workforce toward continually developing their ability to meet expectations of high quality, low cost, and on-time delivery. Kaizen also takes programs that may be seen as having ownership in one department and makes them everyone's responsibility. Kaizen can help companies systematically reduce pollution volume and severity. Kaizen provides companies committed to pollution prevention with a way to focus on enterprise solutions, while moving away from concepts of radical innovation. A systems focus on pollution prevention makes a program broadly supported and results-driven--in other words, sustainable. In this article, we describe the origins of Kaizen concepts, and outline the management styles that Kaizen requires. We explain the difference between Kaizen methods and the "radical innovation" approach that has become prevalent among American companies.

Samples inoculated with 10 super(2) type B or E spores per g prior to pasteurization remained nontoxic for 120 days at 10 degree C and for 15 days at 25 degree C. With 10 super(4) type E spores per g and 80 degree C pasteurization, greater than or equal to 2.4 and 2.7% WPS was required for inhibition at 10 and 25 degree C storage, respectively. Pasteurization at 85 degree C decreased the inhibitory level of WPS to 2.1% at 10 degree C and to 2.4% at 25 degree C. When the inoculum was 10 super(4) type B spores per g, samples with 2.7% WPS were toxic after 80 days of storage at 10 degree C. Samples inoculated with 10 super(3) type B spores per g and processed at 85 degree C remained nontoxic for 15 days at 25 degree C with a WPS of greater than or equal to 2.4%. When pasteurization was carried out before inoculation and packaging, 1.8% WPS prevented toxin production by 10 super(2) and 10 super(4) type E spores per g for 30 days at 10 degree C, and this time period increased as the WPS concentrations increased. Three percent WPS prevented toxin production by 10 super(4) type E spores per g in vacuum-packaged analogs stored 110 days at 10 degree C. Pasteurization processes used in these experiments, however, do not inactivate the heat-resistant proteolytic types of Clostridium botulinum. Therefore, the most important factor controlling the growth of this bacterium is continuous refrigeration below 3.0 degree C or frozen storage of the finished product.

AN - 18306397; 5355538 AB - Pacific herring (Clupea pallasi) in Prince William Sound (PWS) were affected by two major events in the past decade: the Exxon Valdez oil spill in 1989 and a 75% collapse in the adult population in 1993. In this review published data from industry and government sources are reviewed and compared. Combining site-specific estimates of exposure and recent laboratory effects thresholds, 0.4-0.7 mu g times L super(-1) total polynuclear aromatic hydrocarbons, it is concluded that 25-32% of the embryos were damaged in PWS in 1989. Significant effects extended beyond those predicted by visual observations of oiling and by toxicity information available in 1989. Oil-induced mortality probably reduced recruitment of the 1989 year class into the fishery, but was impossible to quantify because recruitment was generally low in other Alaskan herring stocks. Significant adult mortality was not observed in 1989; biomass remained high through 1992 but declined precipitously in winter 1992-1993. The collapse was likely caused by high population size, disease, and suboptimal nutrition, but indirect links to the spill cannot be ruled out. These concepts have broad application to future oil spill assessments. For example, safety standards for dissolved aromatics should reflect the previously unrecognized high toxicity of polynuclear aromatic hydrocarbons to adequately protect critical life stages.

Movements and diving patterns of seals studied at French Frigate Shoals (FFS) Atoll indicated two areas where five males out of 33 instrumented seals dove deep enough (300-500 m) to encounter commercially sought deep-water corals. Submarine surveys conducted at each location found beds of gold (Gerardia sp.) and pink (Corallium sp.) precious coral suggesting an overlap between the foraging habitat of some seals and the target of the coral fishery. Areas adjacent to the coral beds that were visually censused using submersibles showed significantly fewer precious corals. Precious coral beds were not found on previous submarine surveys at other regions around FFS, supporting the notion that seals were selecting the areas with corals as forage habitat. Five male seals were fitted with back-mounted video cameras to document feeding among precious corals. None of the five seals dove deep enough to encounter precious corals (>300 m). However, three of the seals visited beds of black coral (Cirrhipathes sp.) at shallower depths ( similar to 80 m). One seal was observed revisiting the black coral beds on three successive nights to feed on fish hiding among the coral stems.

AN - 18254510; 5317184 AB - We conducted shore-based sighting surveys to estimate the number of northbound migrating gray whale calves passing Piedras Blancas, California, for seven consecutive years (1994-2000). In addition, we conducted aerial surveys to determine offshore distribution of the migration in 1994 and 1995, measured day/night migration rates with thermal sensors in 1994-1996, and maintained concurrent replicate watches near the peak of each migration to estimate the proportion of the cow/calf pairs missed by the standard watch team. During good weather, we counted 325, 194, 407, 501, 440, 141, and 96 calves during 1994-2000, respectively. Correcting these counts for periods not on watch and for calves missed, produced final estimates of 945 calves (SE = 68.21) for 1994, 619 calves (SE = 67.19) for 1995, 1,146 calves (SE = 70.67) for 1996, 1,431 calves (SE = 82.02) for 1997, 1,388 calves (SE = 91.84) for 1998, 427 calves (SE = 41.10) for 1999, and 279 calves (SE = 34.79) for 2000. Calf production indices (calf estimate/total population estimate) are 4.2%, 2.7%, 4.8%, 5.8%, 5.5%, 1.7%, and 1.1% for the years 1994-2000, respectively. Fluctuations in calf production over this time period were positively correlated with the length of time that primary feeding habitat was free of seasonal ice during the previous year.

In an effort to reduce the number of ship strikes, NOAA and the U.S. Coast Guard have developed and implemented Mandatory Ship Reporting systems (MSR). The systems were endorsed by the International Maritime Organization - a specialized organization of the United Nations. The systems became operational in July 1999. When ships greater than 300 gross tons enter two key right whale habitats - one off the northeast U.S. and one off the southeast U.S.-- they are required to report to a shore-based station. In return, ships receive a message about right whales, their vulnerability to ship strikes, precautionary measures the ship can take to avoid hitting a whale, and locations of recent sightings. The reports from ships entering the systems are automatically sorted and stored in a database for subsequent analysis. These data provide a portrait of ship traffic in areas where right whales aggregate and therefore useful in developing measures to reduce the threat of ships striking whales. This report is a summary of the incoming ship reports in both MSR systems from July 1999 to July 2000. Using the ship reports, ship traffic volume and patterns in right whale habitats is characterized.

In order for science to fulfill its potential in the arena of salmon recovery planning, several shortcomings of the science and its application to decision-making must be rectified. The definition of conservation units using genetic and phylogenetic inference needs to be sharpened. Ecological analyses must get beyond casting blame for past declines in salmon numbers and examine mixed strategies of management that consider interactions between hatcheries, harvest, hydropower, and habitat factors as well as background natural stresses and invasive species. Glib acceptance of expert opinion and extrapolated or inferred data should be tempered. To deal with uncertainty, recovery teams should engage in scenario analyses in which a wide variety of assumptions are played out. Finally, there is a pressing need for analyses aimed at determining what circumstances and communication strategies give science an effective voice in decision-making.

Whole-reef censuses in 1983 and 2000 at Looe Key National Marine Sanctuary in the Florida Keys provide estimates of areal loss of live Acropora spp. cover. Area (square meters) of live coral cover was quantified from depiction on scaled base maps of extent of coral cover observed by a snorkeler on each reef spur at each census. Certain thickets appear to have been persistent (though none expanded), but the total area of live A. palmata at Looe Key is estimated to have declined by 93% and A. cervicornis by 98% during this 17-year interval. It is likely that acroporid populations may have already undergone substantial decline prior to our initial census in 1983.

A modified version of the swirling flask effectiveness test was conducted at temperatures of 3, 10 and 22 degree C with salinities of 22ppt and 32ppt. Petroleum dispersed into the water column following application of dispersant was measured by gas chromatography with flame ionization detection. Based on comparison of unresolved complex mixtures, dispersants dispersed less than 40% of the fresh oil and less than 10% of the weathered oil and were most effective (25-75%) when used to disperse a stable oil/water emulsion at 10 degree C. At the combinations of temperature and salinity most common in the estuaries and marine waters of Alaska, dispersants effectiveness was less than 10%, the detection limits of the tests. The results indicate that oil weathering state, seawater salinity and temperature are important factors affecting dispersant performance, however because our laboratory tests were conducted at low mixing energy, considerable caution should be used in extrapolating these laboratory studies to field conditions.

ER - TY - JOUR T1 - A Review of Stream Restoration Techniques and a Hierarchical Strategy for Prioritizing Restoration in Pacific Northwest Watersheds AN - 16142588; 5372144 AB - Millions of dollars are spent annually on watershed restoration and stream habitat improvement in the U.S. Pacific Northwest in an effort to increase fish populations. It is generally accepted that watershed restoration should focus on restoring natural processes that create and maintain habitat rather than manipulating instream habitats. However, most process-based restoration is site-specific, that is, conducted on a short stream reach. To synthesize site-specific techniques into a process-based watershed restoration strategy, we reviewed the effectiveness of various restoration techniques at improving fish habitat and developed a hierarchical strategy for prioritizing them. The hierarchical strategy we present is based on three elements: (1) principles of watershed processes, (2) protecting existing high-quality habitats, and (3) current knowledge of the effectiveness of specific techniques. Initially, efforts should focus on protecting areas with intact processes and high-quality habitat. Following a watershed assessment, we recommend that restoration focus on reconnecting isolated high-quality fish habitats, such as instream or off-channel habitats made inaccessible by culverts or other artificial obstructions. Once the connectivity of habitats within a basin has been restored, efforts should focus on restoring hydrologic, geologic (sediment delivery and routing), and riparian processes through road decommissioning and maintenance, exclusion of livestock, and restoration of riparian areas. Instream habitat enhancement (e.g., additions of wood, boulders, or nutrients) should be employed after restoring natural processes or where short-term improvements in habitat are needed (e.g., habitat for endangered species). Finally, existing research and monitoring is inadequate for all the techniques we reviewed, and additional, comprehensive physical and biological evaluations of most watershed restoration methods are needed.

The importance of coral reef ecosystems, in particular, may be seen in their numerous ecological, aesthetic, economic and cultural functions. Pacific islanders recognize that healthy reefs are essential for creation, support, protection and repair of their islands, and serve as a living pantry for the subsistence harvest and consumption of many reef organisms. The ability of coral reef ecosystems to exist in balanced harmony with other naturally occurring competing/limiting physico-chemical and biological agents has been severely challenged in the last several decades by the dramatically increased negative and synergistic impacts from poorly managed anthropogenic activities. In addressing these threats, a paradigm shift may be occurring in the evolution of the role of scientists in society from simply observers of the natural world with tenuous linkages to resource managers and the public, to partners in modern society's quest for answers to pressing questions related to sustainable use and conservation of coral reef resources. Management principles are beginning to include human motivation and responses as part of coral ecosystems being studied and managed. Managers of coral reef resources face the challenge of balancing conservation and development objectives in the context of the inherent uncertainty of natural systems and the political and social pressures of human systems. Working together, scientists, managers and policymakers can develop priorities and strategies for societal and economic decisions that are strongly coupled with an increasingly comprehensive understanding of the environment. This in turn will lead to both socio-economic health and coral ecosystem health. Employing this new paradigm for interactions between scientists, managers and policymakers, participants of the Pacific Regional ICRI Symposium in Noumea, New Caledonia developed three principal sets of recommendations for addressing natural and anthropogenic threats to coral reefs in Pacific Island Nations: (1) develop and implement a new overarching Participatory Island Ecosystem Management System (PIEMS) for each of the Pacific Island Nations; (2) improve existing, as well as design and implement new, capacity-building programs; and (3) improve scientific understanding of coral reef ecosystems with effective translation and transfer of information. Details for each set of recommendations are provided in this paper.

ADIOS forecasts the weathering processes and characteristics of oil slicks. Based on new research results and analysis since the first version was released, a major update revises and improves previous algorithms, plus adds new modules for other weathering processes and for spill cleanup strategies. The weathering processes included in the new version, called ADIOS2, are spreading, evaporation, dispersion, sedimentation, and emulsification. The user cleanup options are dispersants, in-situ burning, and skimming. Different types of release scenarios can be simulated and the user is allowed to enter ranges for selected input variables with the resulting uncertainty displayed in the model output.

Recovery criteria1 are an ESA-required component of recovery plans. Because some populations of endangered large whale species have grown in abundance, they may be candidates for a change in status from endangered to threatened, or removal from the List of Threatened and Endangered Wildlife. NMFS has not developed and adopted recovery criteria for most of these taxa. Workshop objectives were to develop (1) a general framework for the development of recovery criteria that would be applicable to most marine mammal species, large whale species in particular, and (2) specific criteria that can be used to apply the framework to specific populations. A major goal was to use North Pacific and North Atlantic right whales as case studies, and to develop a specific set of recovery criteria which could be used for these populations. The workshop reviewed the legislative and regulatory history of recovery criteria for listed species.

A quantitative resource inventory was funded in 1983 by NOAA in cooperation with the University of Miami, the United States Geological Survey, and the Florida Department of Natural Resources. The objective of the study was to quantitatively inventory selected resources of LKNMS in order to allow future monitoring of changes in the Sanctuary as a result of human or natural processes. This study, referred to as Phase I, gives a brief summary of past and present uses of the Sanctuary; and describes general habitat types, geology and sediment distribution, coral abundance and distribution, the growth history of the coral Montastraea annularis, reef fish abundance and distribution, and status of selected resources. An interpretation of the results of the survey are provided for management consideration. The results are expected to provide fundamental information for applied management, natural history interpretation, and scientific research.

The Estuarine Living Marine Resources (ELMR) program was founded by the Biogeography Program of the former Strategic Environmental Assessments (SEA) Division of the National Ocean Service (NOS). Through the years, it has been conducted jointly by NOS, NOAA's National Marine Fisheries Service (NMFS), and other agencies and institutions. The nationwide 'Base ELMR' data base was completed in 1994, and includes data for 153 species found in 122 estuaries and coastal embayments in five regions. Regional revisions were completed for the Gulf of Mexico and Southeast in 1998, and plans are under way to update the Mid-Atlantic and North Atlantic regions in 2000-2001. This report provides a national overview of the evolution, accomplishments, and regional results of the ELMR program to date.

AN - 1521396709; 5425598 AB - Temporally consistent patterns in the spatial distribution of returning adult coho salmon (Oncorhynchus kisutch) to explore relationships between salmon abundance, landscape characteristics, and land use patterns in the Snohomish River watershed, Wash. The proportion of total adult coho salmon abundance supported by a specific stream reach was consistent among years, even though interannual adult coho salmon abundance varied substantially. Wetland occurrence, local geology, stream gradient, and land use were significantly correlated with adult coho salmon abundance. Median adult coho salmon densities in forest-dominated areas were 1.5-3.5 times the densities in rural, urban, and agricultural areas. Relationships between these habitat characteristics and adult coho salmon abundance were consistent over time. Spatially explicit statistical models that included these habitat variables explained almost half of the variation in the annual distribution of adult coho salmon. This analysis indicates that such models can be used to identify and prioritize freshwater areas for protection and restoration.

First found in the Everglades National Park in 1983, the fish has since spread to Naples and West Palm Beach areas, and has become abundant in man-made freshwater canals and estuarine mangroves, and now supports a small sport fishery. Anglers hold mixed opinions about the desirability of a Mayan cichlid fishery. Because of the ecological and economic significance of this introduction, research on the life history of the Mayan cichlid was conducted. The age, growth, and mortality patterns of this fish, collected from the southeastern Everglades, were determined. Mayan cichlids appear to grow more slowly and live longer in Florida than has been reported from native Mexican habitats. Further research and monitoring are needed to understand their possible impacts on native fishes and ecosystems.

Catches of associated species by tuna purse seiners in the WIO were estimated based on scientific observations from aboard Soviet purse seiners from 1986-92. More than 40 fish and marine animal species were recorded, of which only the yellowfin and skipjack tuna were target species. Average levels of bycatch per set and per 1000 t of target species, non-recorded annual bycatch of the major fish groups, turtle and whale bycatch, and other statistics are summarized. Gaps in recording data hinder assessment of tuna fishery impacts on the WIO ecosystem. Further monitoring by scientific observers on board tuna purse-seine and longline vessels fishing in the WIO is recommended.

Skeletochronological data on changes in humerus diameter growth were used to estimate turtle age. Correction factor and spline integration age estimation methods are explained. Analysis results are summarized. The spline-integration method models the curvilinear relationship between humerus diameter and the width of periosteal growth increments in the humerus, and offer several advantages over the correction-factor estimation approach.

Changes in lobster diets with growth were studied, and the implications of such changes for conservation of lobster stocks are discussed. An ontogenetic diet shift was observed in which the stomach content proportions of the three major food items-bivalves, animal tissue (flesh), and rock crabs-changed with lobster size. The finding that early juvenile lobsters are primarily predators or scavengers means that efforts to develop and implement artificial reefs will have to ensure that they are well colonized by readily available benthic prey of high nutritive value to juvenile lobsters.

Reduced juvenile survival is the proximate cause of declines but the ultimate cause is unknown. Eastern Steller sea lion stocks remain threatened, but western stocks now are considered endangered. The patterns and causes of population declines and trends and status of eastern stocks at their southern rookeries, particularly at the South Farallon Islands off the California coast, were studied. Seasonal variation in numbers among sexes and age classes, trends in numbers from 1974 to 1996 by age class, sex, and season, and averages and trends in pup production, reproductive rate, and adult sex-ratio were determined. Survey findings are summarized. Significant declines were detected in numbers of pups and the ratio of adult females to adult males. Further studies are needed to learn if reduced adult female numbers resulted from reduced juvenile or adult survival, or from changes in the geographic distribution of females.

Permit are the basis of an important recreational and commercial fishery in Florida, yet little is known about permit biology. Growth, longevity, length and age at which permit mature, and spawning in South Florida waters were studied using 536 permit collected from the Tampa Bay and Florida Keys areas. Growth and reproductive data are summarized. Some 50% of females are estimated to reach sexual maturity by 547 mm and age 3.1 yr, while 50% of males are estimated to reach maturity by 486 mm and 2.3 yr. Florida regulations restrict the maximum size of permit caught to 20 in, so most fish harvested are sexually immature. Spawning stock biomass of permit could decrease quickly in response to moderate levels of fishing mortality. Regulations restricting harvest levels appear to be justified.

AN - 85246144; pmid-11800866 AB - We demonstrate a simple optical clock based on an optical transition of iodine molecules, providing a frequency stability superior to most rf sources. Combined with a femtosecond-laser-based optical comb to provide the phase coherent clock mechanism linking the optical and microwave spectra, we derive an rf clock signal of comparable stability over an extended period. Measurements suggest the stability ( 5x10(-14) at 1 s) of the cw laser locked on the iodine transition is transferred to every comb component throughout the optical octave bandwidth (from 532 to 1064 nm) with a precision of 3.5x10(-15). Characterization of the performance of the optical clock shows (in-)stability below 3x10(-13) at 1 s (currently limited by the microwave sources), and 4.6x10(-13) over one year.

Two eco-types of killer whales, 'transient' and 'resident', occur in all of these regions. These eco-types are genetically distinct and differ in various aspects of morphology, vocalization patterns, diet and habitat use. Various genetic and photo-identification studies of eastern North Pacific killer whales have provided information on the male-female composition of most of these resident pods and transient groups, as well as the approximate ages, reproductive status and putative recruitment order (birth order) of the individual whales. Biopsy blubber samples of free-ranging resident and transient killer whales from the Kenai Fjords/Prince William Sound, AK region were acquired during the 1994-1999 field seasons and analyzed for selected organochlorines (OCs), including dioxin-like CB congeners and DDTs. Concentrations of OCs in transient killer whales (marine mammal-eating) were much higher than those found in resident animals (fish-eating) apparently due to differences in diets of these two killer whale eco-types. Certain life-history parameters such as sex, age and reproductive status also influenced the concentrations of OCs in the Alaskan killer whales. Reproductive female whales contained much lower levels of OCs than sexually immature whales or mature male animals in the same age class likely due to transfer of OCs from the female to her offspring during gestation and lactation. Recruitment order also influenced the concentrations of OCs in the Alaskan killer whales. In adult male residents, first-recruited whales contained much higher OC concentrations than those measured in non-first-recruited (e.g. second recruited, third recruited) resident animals in the same age group. This study provides baseline OC data for free ranging Alaskan killer whales for which there is little contaminant information.

Here we report on the first broad and systematic survey of hydrothermal emissions generated along a submarine arc front. More than half (seven of 13) of the volcanoes surveyed along 260 km of the southern Kermadec arc, NE of New Zealand, are hydrothermally active. Our results indicate that volcanic arcs represent a previously unheeded but potentially extensive source of shallow (<2 km water depth) vent fields expelling fluids of a unique and heterogeneous composition into the oceans.

AN - 72425516; 11827117 AB - Marine debris threatens Northwestern Hawaiian Islands' (NWHI) coral reef ecosystems. Debris, a contaminant, entangles and kills endangered Hawaiian monk seals (Monachus schauinslandi), coral, and other wildlife. We describe a novel multi-agency effort using divers to systematically survey and remove derelict fishing gear from two NWHI in 1999. 14 t of derelict fishing gear were removed and debris distribution, density, type and fouling level documented at Lisianski Island and Pearl and Hermes Atoll. Reef debris density ranged from 3.4 to 62.2 items/km2. Trawl netting was the most frequent debris type encountered (88%) and represented the greatest debris component recovered by weight (35%), followed by monofilament gillnet (34%), and maritime line (23%). Most debris recovered, 72%, had light or no fouling, suggesting debris may have short oceanic circulation histories. Our study demonstrates that derelict fishing gear poses a persistent threat to the coral reef ecosystems of the Hawaiian Archipelago.

AN - 62190312; ED470445 AB - This report describes 10 projects funded by the federal Technology Opportunities Program, in which people in isolated regions are finding ways to connect to new information networks and are reaping social, economic, and educational benefits. In the sprawling Navajo Nation, where many families lack even basic telephone service, local tribal governments are using satellite connections to connect with the outside world. In rural Mayville, North Dakota, a state university is working with local leaders to establish a homegrown technology industry and halt a long economic decline. A project of the U.S. Bureau of Reclamation is showing how timely collection and distribution of information can improve the efficiency of irrigation systems and help farmers in Utah's Sevier River basin stretch limited water resources. In coastal Maine, better information systems are improving the delivery of social services to needy families. Two telemedicine projects, which deliver health care services and medical education in rural Maine and Vermont, show that telemedicine comprises various tools rather than a single technology and that human relationships make it work. Broadband videoconferencing is being used by Marshall University (West Virginia) to make distance education more personal, and is improving extension services offered by North Dakota State University. The Virtual Chautauqua use video and audio streaming technology to bring the performing arts into rural Colorado classrooms, while Dance Partners uses videoconferencing to bring dance education to remote Minnesota communities.

Under appropriate conditions, these representations can be used for a variety of purposes such as identifying, classifying, and understanding the physical properties of materials. Critical to these applications is the ability to construct a unique representation of the lattice. The vital link that enabled this theory to be realized in practice was provided by the 1970 paper on the determination of reduced cells. This seminal paper led to a mathematical approach to lattice analysis initially based on systematic reduction procedures and the use of standard cells. Subsequently, the process evolved to a matrix approach based on group theory and linear algebra that offered a more abstract and powerful way to look at lattices and their properties. Application of the reduced cell to both database work and laboratory research at NIST was immediately successful. Currently, this cell and/or procedures based on reduction are widely and routinely used by the general scientific community: (i) for calculating standard cells for the reporting of crystalline materials, (ii) for classifying materials, (iii) in crystallographic database work (iv) in routine x-ray and neutron diffractometry, and (v) in general crystallographic research. Especially important is its use in symmetry determination and in identification. The focus herein is on the role of the reduced cell in lattice symmetry determination.

Over that time period, portland cement concrete has become one of the most important of our construction materials for roads, buildings, and other large municipal structures. At the beginning of the 20th century our understanding of portland cement composition, performance, use in concrete, and how the concrete performs in harsh environments was lacking. The efforts of NIST have served to advance construction materials science and technology through the combined efforts of experimental, field study, and theoretical computational materials science. One major achievement in the late 1920s, derived from studies on phase equilibria in cement clinker, allows calculation of potential cement clinker composition. Known as the Bogue calculation, this continues to be an essential tool in cement plant process control to this day. Additionally, contributions of NIST scientists to our knowledge of the chemistry and nature of cement hydration products have been crucial in our understanding of cement hydration and concrete durability. Today, computational materials science is a rapidly developing discipline, and NIST is developing tools incorporating predictive models aided by empirical studies. Examples include a computer-integrated knowledge system for prediction and optimization of performance and life-cycle cost of high performance concrete and the Virtual Cement and Concrete Testing Laboratory. Understanding the relationships between material and performance properties has not been confined only to portland cements. One of the longest running experiments at NIST, the stone test wall, has stood for over 50 years as one of the world's largest single collections of building stone, and is invaluable for studying weathering effects associated with stone mineralogy and texture. Standards development has also been promoted through participation on ASTM subcommittees on stone, cement, and concrete. The Cement and Concrete Reference Laboratory, established in 1929, continues to provide testing and training for outside laboratories and maintains a historical record of test data on construction materials.

The weather-band peak, in particular, has a number of interesting features. It is strongest in close lateral proximity to the ridge and strongest near ridge depth; intensification near the ridge is characteristic of trapped motion. Spectral peak intensities vary seasonally, with largest amplitudes occurring in autumn and winter; seasonal variation suggests that surface weather is forcing flow at depth. Together, trapping and seasonality indicate opportunistic amplification of oscillatory motion at the ridge. At all frequencies, forcing, topography, and stratification together shape current and hydrographic distributions near the ridge. Effects of those interactions for subinertial motion are quantified here using a primitive equation numerical model. Forcing period (1-10 days) and friction are the principal dependencies examined. Results show that flow over the Juan de Fuca Ridge can be amplified by factors of 3-4 for diurnal and up to a factor of 7 for weather-band frequencies. Amplification is ridge trapped, with effects extending many hundreds of meters upward and extending 5-10 km laterally for 5-day-period flow; the strength and area of amplification increase with increasing period over the 1- to 10-day-period band. Oscillatory weather-band flow leads to vertical velocities on the order of 0.3 cm s (super -1) on ridge flanks, which in turn cause periodic temperature (T) and salinity (S) variations with amplitudes of as much as 0.05 degrees C and 0.01 practical salinity units, respectively. The vertical motion and consequent vertical displacement (>100 m) lead to isotherms that plunge below the crest alternately each side of the ridge, a distribution observed in conductivity-temperature-depth transect data. Near the ridge crest, cross-ridge baroclinic pressure gradients caused by cyclically plunging isopycnals are in near-geostrophic balance with the Coriolis force associated with along-ridge flow. Along-ridge current amplification is therefore closely tied to isopycnal movement up and down ridge flanks. Since weather-band oscillations lead to much larger cross-ridge baroclinic pressure gradients than do diurnal motions of the same amplitude, weather-band forcing causes greater along-ridge current amplification. Results vary strongly with forcing period and direction of forcing with respect to the ridge but depend only moderately on friction and turbulent mixing coefficients.

AN - 20718944; 6711704 AB - Hydrologists have traditionally assumed that the annual maximum flood process at a location is independent and identically distributed. While nonstationarities in the flood process due to land use changes have long been recognized, it is only recently becoming clear that structured interannual, interdecadal, and longer time variations in planetary climate impart the temporal structure to the flood frequency process at flood control system design and operation timescales. The influence of anthropogenic climate change on the nature of floods is also an issue of societal concern. Here we focus on (1) a diagnosis of variations in the frequency of floods that are synchronous with low-frequency climate state and (2) an exploration of limiting flood probability distributions implied by a long simulation of a model of the el Nino/Southern Oscillation. Implications for flood risk analysis are discussed.

Policy (ESCAP) that the Census 2000 Redistricting Data not be adjusted based on the Accuracy and Coverage Evaluation (A.C.E.). By mid-October 2001, the Census Bureau had to recommend whether Census 2000 data should be adjusted for future uses, such as the census long form data produets, post-censal population estimates, and demographic survey controls In order to inform that decision, the ESCAP requested that further research be conducted. Between March and September 2001, the Demographic Analysis-Population Estimates (DAPE) research project addressed the discrepancy between the demographic analysis data and the A.C.E. adjusted estimates of the population. Specifically, the research examined the historical levels of the components of population change to address the possibility that the 1990 Demographic Analysis understated the national population and assessed whether demographic analysis had not captured the full population growth between 1990 and 2000. Assumptions regarding the components of international migration (specifically, emigration, temporary migration, legal migration, and unauthorized migration) contain the largest uncertainty in the demographic analysis estimates. Therefore, evaluating the components of international migration was a critical activity in the DAPE project. This report focuses on the evaluation of the U.S. Census Bureau's estimated stock of legal temporary migrants in 1990 and 2000. Specifically, the review process validated the estimates of temporary migrants in 1990 and created an intermediate estimate for 2000. To produce the estimate of net temporary migrants, the Census Bureau developed criteria, related to visa requirements, to identify people who were likely to be resident temporary migrants in the 1990 census. Because the preliminary data from Census 2000 were unavailable for several necessary variables for the algorithm (e.g., industry and income), data from the Census 2000 Supplementary Survey were used for the 2000 estimate. Our evaluation resulted in a temporary migrant stock estimate of 487,453 in 1990 and 781,507 in 2000. For both dates, temporary migrants included more men than women, were likely to be non-Hispanic, and the largest numbers were between the ages of 18 and 29. Future research will focus on an evaluation of the criteria used for the algorithm, and an adaptation of the algorithm to other surveys, such as the Current Population Survey and the American Community Survey, to facilitate in the production of annual estimates of temporary migrants.

AN - 19932586; 5472741 AB - The U.S. Census Bureau produces national population estimates on an annual basis using methodology that incorporates the three main determinants of population change: births, deaths, and net migration. Net international migration plays an integral role in determining both the size and demographic composition of the population at the national level. It is the most complex determinant of population change, and its complete measurement involves the measurement of several sub-components, each one using separate methodology. In view of the fact that these sub-components are estimated separately, each is subject to differing levels of uncertainty or bias. This paper provides a detailed discussion of the definitions, methodologies, assumptions, and data sources used to measure net international migration, including a brief description of estimates for geography and demographic characteristics. Following the discussion of the sub-components of net international migration, the strengths and limitations of each are presented along with potential research and developments.

In order to inform that decision, the ESCAP requested that further research be conducted. Between March and September 2001, the Demographic Analysis-Population Estimates (DAPE) research project addressed the discrepancy between the demographic analysis data and the A.C.E. adjusted estimates of the population. Specifically, the research examined the historical levels of the components of population change to address the possibility that the 1990 Demographic Analysis understated the national population and assessed whether demographic analysis had not captured the full population growth between 1990 and 2000. Assumptions regarding the components of international migration (specifically, emigration, temporary migration, legal migration, and unauthorized migration) contain the largest uncertainty in the demographic analysis estimates. Therefore, evaluating the components of international migration was a critical activity in the DAPE project. This report focuses on the evaluation of the U.S. Census Bureau's estimates of the foreign-born population by migrant status in 2000. In particular, we assess the assumptions used to estimate the various types of international migrants (legal immigrants, temporary migrants, unauthorized migrants, and emigrants) and the effect of alternative assumptions in estimating the size of the foreign-born population. By reviewing alternative assumptions about the types of international migrants, we assess the completeness of coverage of the foreign-born population in Census 2000, and the reasonableness of the resulting Demographic Analysis (DA) estimates.

Exposure to toxic contaminants may indirectly affect populations of salmon, for example, by increasing susceptibility to opportunistic pathogens at lower exposure levels than are necessary to observe direct toxicity, especially fish that migrate through contaminated estuaries and waterways. We have an ongoing program that measures contaminant levels and associated biological effects in juvenile Pacific salmon. As part of this effort, tissues of juvenile chinook salmon (Oncorhynchus tshawytscha) from various estuaries in Washington and Oregon were analyzed for polychlorinated biphenyls (PCBs), DDTs and aromatic hydrocarbons. As expected, whole bodies and stomach contents of chinook salmon from urban estuaries contained higher levels of bioaccumulative PCBs and DDTs than did the tissues of fish from non-urban estuaries. Surprisingly, however, juvenile chinook salmon from some hatcheries in Washington and Oregon contained levels of PCBs and DDTs that were comparable to those measured in juveniles from urban estuaries. As a result of these findings, we analyzed several samples of fish food to determine if hatchery food was a potential source of contaminants in hatchery fish. Hatchery food contained a wide range of contaminant concentrations and juvenile chinook salmon from the hatcheries are bioaccumulating chemical contaminants from certain fish foods as well as from other sources in estuaries.

The experiments are based on 43-year (1955-98) observed SST data and 20-year (1979-98) OLR record. The aim is to study the role of tropical convection in improving the predictions of the interannual variability of the Sahel summer rainfall. Forecast skills for OLR and SST predictor fields are estimated using a cross-validation scheme. Average region-wide correlation skill for OLR is 0.368, which is slightly higher than skill for SST based on a 43-year record (0.308). However, much of the skill in the latter is associated with long term trends. Skill for OLR outperforms significantly that of SST based on a 20-year historical record. Hindcasts for the Jul-Sep Sahel rainfall in 1997 and 1999 show an improvement over SST in the predictions of the interannual variability where OLR is used as predictor field.

The data were interpreted with a sequential reaction model that included reaction of aldehydes with hydroxyl radical and formation or loss of PANs mediated by peroxyacyl radicals {RC(O)OO}. The comparison of the measured ratios with those predicted by the model showed a disagreement for PAN/acetaldehyde and PPN/propanal in Nashville, but agreement in Houston. The Nashville data set also showed a disagreement in the case of PAN/acetaldehyde and MPAN/methacrolein, but agreement for PPN/propanal and MPAN/methacrolein. These features were consistent with the relative importance of isoprene to PAN formation at each site. The ratios were found to be highly correlated with ozone mixing ratios at each site.

The Remote Sensing Division (RSD) within NGS, conducts photogrammetric surveys to photograph and when prioritized, compile shoreline and associated data for application to the Office of Coast Survey's nautical charts. The update cycle for a nautical chart varies from as often as every 6 months to as infrequently as 12 years depending on factors including the rate of cultural and natural changes. This shoreline data is available to the coastal GIS community through the National Geodetic Survey Shoreline Data Explorer website. The Coast and Shoreline Change Analysis Program (CSCAP), managed by NGS, acquires contemporary high-resolution imagery to evaluate ports. The imagery is accurately georeferenced and compared with the nautical chart to detect changes. The analysis of these discrepancies is used to determine which ports or areas within a port require expensive photogrammetric survey mapping.

Landfall position and time forecasts are skillful at all forecast time periods and are more skillful than Atlantic basin track forecasts as a whole, but within 30 h of predicted landfall, timing errors demonstrate an early bias of 1.5-2.5 h. Landfall forecasts are most accurate for storms moving at oblique or normal angles to the coastline and slow-moving storms. During the last quarter century, after adjustment for forecast difficulty, no statistically significant improvement or degradation is noted for landfall position forecasts. Time of landfall forecasts indicate no degradation at any period and significant improvement for the 19-30-h period. The early bias and lack of improvement are consistent with a conservative or "least regret" forecast and warning strategy to account for possible storm accelerations. Landfall timing uncertainty is similar to 11 h at 24 and 36 h, which suggests that hurricane warnings could be disseminated about 12 h earlier (at 36 h, rather than 24 h, before predicted landfall) without substantial loss of lead time accuracy (although warning areas necessarily would be larger). Reconsideration of National Weather Service Strategic Plan and United States Weather Research Program track forecast goals is recommended in light of these results.

Dominant fry from enriched tanks and natural stream exhibited greater frequencies of threat displays than dominant fry reared in conventional tanks. Fry reared in the natural stream exhibited greater territory overlap than fry from either hatchery environment. Overall, the results suggest that enriched hatchery environments may act to ameliorate some but not all changes in social behaviour that result from hatchery rearing.

Within the study area, the species' ranges, and therefore the number of distinct ecological regions inhabited differ considerably, with pink and chum salmon limited to the northern areas and chinook salmon and steelhead distributed over the widest geographic range. The species showed comparable differences in the patterns of life history and genetic diversity, with chinook and sockeye salmon and steelhead having the most major diversity groups and pink, chum and coho salmon having the least. Both life history and genetic diversity showed a strong, positive correlation with the extent of ecological diversity experienced by a species, and the correlation between the number of major genetic and life history groups within a species was even stronger (r=0.96; P< 0.05). Departures from these general diversity relationships found in some species (especially sockeye and coho salmon and cutthroat trout) can be explained by different interactions with the freshwater environment and, for cutthroat trout, by the occurrence of substantial intrapopulational diversity in life history traits, a hierarchical level not considered in this study.

Self-siphoning rain gauges were chosen for use on these buoys because they can be calibrated at PMEL before and after deployment. The rainfall data are recorded at 1-min intervals, from which daily mean rate, standard deviation, and percent time raining are calculated and telemetered to PMEL in real time. At the end of the deployment, the 1-min, internally recorded data are recovered and processed to produce 10-min rain rates. Field data from a subset of these rain gauges are analyzed to determine data quality and noise levels. In addition, laboratory experiments are performed to assess gauge performance. The field data indicate that the noise level during periods of no rain is 0.3 mm h super(-1) for 1-min data, and 0.1 mm h super(-1) for 10-min data. The estimated error in the derived rain rates, based on the laboratory data, is 1.3 mm h super(-1) for 1-min data, and 0.4 mm h super(-1) for 10-min data. The error in the real-time daily rain rates is estimated to be at most 0.03 mm h super(-1). These error estimates do not take into account underestimates in accumulations due to effects of wind speed on catchment efficiency, which, though substantial, may be correctable. Estimated errors due to evaporation and sea spray, on the other hand, are found to be insignificant.

The structure reveals a fold typical of S-adenosyl-L-methionine-dependent (AdoMet) methyltransferase enzymes. Moreover, a processed cofactor, S-adenosyl-L-homocysteine (AdoHcy), is bound to the enzyme, further confirming the biochemical function of HI0319 and its sequence family members. An active site arginine, shielded from bulk solvent, interacts with an anion, possibly a chloride ion, which in turn interacts with the sulfur atom of AdoHcy. The AdoHcy and nearby protein residues delineate a small solvent-excluded substrate binding cavity of 162 Angstrom super(3) in volume. The environment surrounding the cavity indicates that the substrate molecule contains a hydrophobic moiety and an anionic group. Many of the residues that define the cavity are invariant in the HI0319 sequence family but are not conserved in other methyltransferases. Therefore, the substrate specificity of YecO enzymes is unique and differs from the substrate specificity of all other methyltransferases sequenced to date. Examination of the Enzyme Commission list of methyltransferases prompted a manual inspection of 10 possible substrates using computer graphics and suggested that the ortho-substituted benzoic acids fit best in the active site.

Methylotrophs and methanotrophs were able to consume MeBr provided at levels that mimicked the tropospheric mixing ratio of MeBr (12 pptv) at equilibrium with surface waters ( approximately 2 pM). Kinetic investigations using picomolar concentrations of MeBr in a continuously stirred tank reactor (CSTR) were performed using strain IMB-1 and Leisingeria methylohalidivorans strain MB2 super(T) -- terrestrial and marine methylotrophs capable of halorespiration. First-order uptake of MeBr with no indication of threshold was observed for both strains. Strain MB2 super(T) displayed saturation kinetics in batch experiments using micromolar MeBr concentrations, with an apparent Ks of 2.4 mu M MeBr and a V sub(max) of 1.6 nmol h super(-1) (10 cells) super(-1). Apparent first-order degradation rate constants measured with the CSTR were consistent with kinetic parameters determined in batch experiments, which used 35- to 1 x 10- fold-higher MeBr concentrations. Ruegeria algicola (a phylogenetic relative of strain MB2 super(T)), the common heterotrophs Escherichia coli and Bacillus pumilus, and a toluene oxidizer, Pseudomonas mendocina KR1, were also tested. These bacteria showed no significant consumption of 12 pptv MeBr; thus, the ability to consume ambient mixing ratios of MeBr was limited to C sub(1) compound-oxidizing bacteria in this study. Aerobic C sub(1) bacteria may provide model organisms for the biological oxidation of tropospheric MeBr in soils and waters.

This paper will show that although increased NWR signal coverage is now being provided, manufactured and metal-built homes can still pose serious problems for the reception of NWR broadcasts. A series of signal reception tests were completed by the Florida Division of Emergency Management. Reception results are presented for a manufactured home and a home built with metal wall studs. This paper shows that an external antenna developed from the test results will effectively improve NWR reception in metal buildings and manufactured homes. The tests further showed that using a simple J-pole external antenna mounted on a window alleviated the attenuation problem. It is hoped that this study's results will alert the public, emergency managers, and other officials to the potential for poor NWR reception in mobile homes and metal buildings, as well as what corrective measures to take. The use of inexpensive, lightweight external antennas and the correct placement of NWRs should be stressed during NWS outreach activities. Obviously it is very important for the public to purchase a NWR, but they must be educated about proper unit placement and/or antenna availability. These education efforts should inform customers, reduce complaints regarding NWR reception, and lead to a safer public.

The discussion is cast in the context of variations in the associations over time, with decadal scale changes emphasized. In the five decades or so for which we have adequate records to reliably analyse the global aspects of ENSO effects on regional climates around the world, we have witnessed one major decadal scale change in the overall pattern of sea-surface temperatures (SST) in the global ocean, and concomitant changes in the atmospheric response to those changes. The analysis underscores the connection between low frequency changes in tropical SST, ENSO and decadal scale changes in the general atmospheric circulation, pointing to the complex interplay between the canonical ENSO system, slow changes in SST in the Indo-Pacific over the last century, and long-term changes in the atmospheric circulation itself.

Today it is the most endangered population of large whale. Their historical summer distribution included the Gulf of Alaska and the southeastern Bering Sea, and that of the endangered western North Pacific population included waters east of Kamchatka, the Okhotsk Sea, and the Sea of Japan. During the intensive whaling era of the 1946s to 1960s, right whales in the southeastern Bering Sea concentrated in deep (>200 m) waters north of Unalaska Island, where they fed on the oceanic copepod Neocalanus cristatus. Here we report the summer distribution, prey, and primary habitat of a remnant population that now occupies a different habitat, the middle shelf of the southeastern Bering Sea, and forages on a different prey, Calanus marshallae. Given this region's large and possibly enhanced interannual and decadal-scale variability in climate and ecosystem response, as well as a long-term trend of warming summer sea-surface temperatures (SSTs), the survival of these right whales is uncertain.

AN - 71374077; 12805797 AB - Significant uncertainty exists in magnitude and variability of ammonia (NH3) emissions, which are needed for air quality modeling of aerosols and deposition of nitrogen compounds. Approximately 85% of NH3 emissions are estimated to come from agricultural nonpoint sources. We suspect a strong seasonal pattern in NH 3 emissions; however, current NH3 emission inventories lack intra-annual variability. Annually averaged NH 3 emissions could significantly affect model-predicted concentrations and wet and dry deposition of nitrogen-containing compounds. We apply a Kalman filter inverse modeling technique to deduce monthly NH3 emissions for the eastern U.S. Final products of this research will include monthly emissions estimates from each season. Results for January and June 1990 are currently available and are presented here. The U.S. Environmental Protection Agency (USEPA) Community Multiscale Air Quality (CMAQ) model and ammonium (NH4+) wet concentration data from the National Atmospheric Deposition Program (NADP) network are used. The inverse modeling technique estimates the emission adjustments that provide optimal modeled results with respect to wet NH4+ concentrations, observational data error, and emission uncertainty. Our results suggest that annual average NH 3 emissions estimates should be decreased by 64% for January 1990 and increased by 25% for June 1990. These results illustrate the strong differences that are anticipated for NH3 emissions.

AN - 36407950; 9070 AB - PURPOSE: The implementation of a fishery management plan (FMP) for the deep-sea red crab fishery off the coast of New England and the Mid-Atlantic is proposed. The fishery management unit is bounded on the south by Cape Hatteras, North Carolina, on the north and east by the coastline of the continental United States and the eastern boundary of the Exclusive Economic Zone. Since the early 1970s, there has been a small directed red-crab fishery in this region. Faced with increasing landings in recent years and increased interest in the fishery from potential new entrants around the country, fishing interests approached the New England Fishery Management Council in late 1999 with a request that the Council manage red crab. In January 2001, faced with an increasing number of vessels targeting the red crab resource, the Council requested that emergency action be taken to prevent overfishing in the fishery while the Council continued to develop an FMP. Emergency regulations were established on May 8, 2001; these regulations will remain in effect until May 14, 2002. All currently available information indicates that there is a limited maximum sustainable yield of red crab of 6.24 million pounds and that four to six vessels fishing at existing levels of capacity represent the likely maximum harvesting effort that can be sustained by the resource. The addition of new vessels, particularly catcher-processor vessels with increased capacity, would threaten not only the resource but also the viability of the established fishery. Key issues identified during scoping for the FMP include those related to the status of the red crab stock, the availability of data on the resource and the fishery, incidental catch and discards of red crabs in other fisheries, the appropriate levels of fishing power, maintenance of consistent supply of red crabs, compliance with marine mammal protection requirements, area of management jurisdiction, and handling mortality. Ten alternatives, including a No Action Alternative (Alternative 10), are considered in this draft EIS. The preferred alternative (Alternative 5) would use a days-at-sea (DAS) allocation based on a target total allowable catch (TAC), in conjunction with a controlled access program, to control fishing effort on the resource. Trip limits would be used to ensure that each trip taken by a red crab vessel was roughly equivalent. The objective of the alternative would be to determine the DAS appropriate to harvest, but not exceed, the target TAC. DAS could be adjusted on an annual basis in response to changing stock conditions and to estimates of the amount of crab likely to be harvested. Some form of trap limit would be established to control the potential fishing power of individual vessels. An incidental catch limit would be established for all vessels not authorized to participate in the directed fishery. In addition the landing of female crabs and the mutilation (claw-snapping) and/or full processing of crabs at sea would be prohibited. POSITIVE IMPACTS: The preferred FMP would prevent overfishing of the red crab resource and overcapitalization of the associated fishery. The plan would allow for the market to control production. Vessels would be able to maximize their outputs from a given level of inputs, assuming that the biomass increased over time. NEGATIVE IMPACTS: Because the calculation of DAS is indirect, the realized catch after one year using all DAS could over- or under-shoot the target TAC.

AN - 36409679; 9061 AB - PURPOSE: The implementation of a plan for the protection of Steller sea lions under the authority of the fishery management plans for groundfish fisheries of the Gulf of Alaska and the Bering Sea and Aleutian Islands is proposed. Within fisheries in the range of the Steller sea lion west of Cape Suckling, the species is considered endangered; within the area east of Cape Suckling, the species is considered endangered. In the core region from Kenai Peninsula to Kiska Island, counts of adult and juvenile sea lions have declined by approximately 80 percent since the population size was estimated in the late 1950s. Five alternatives, including a No Action Alternative (Alternative 1), are considered in this final supplemental programmatic EIS. The primary purpose of the proposed action is to modify the management plan for the pollock, Pacific cod, and Atka mackerel fisheries such that the reconfigured fisheries do not jeopardize the continued existence of Steller sea lions or adversely affect their crucial habitat. If more than one alternative action would accomplish the primary purpose, a secondary objective would be to modify the fisheries such that the reconfiguration minimizes the economic and social costs that would be imposed on the commercial fishing industry and the associated coastal communities. The preferred alternative (Alternative 4) would involve an area and fishery specific approach. The approach would allow for different types of management measures in the three affected areas. Essential measures would include fishery-specific closed areas around rookeries and hallouts, together with seasonal and catch apportionments. Three options for closure areas would be considered; these include small boat exemptions for the Chignik and /or Unalaska tribes and gear-specific zones for the Gulf of Alaska Pacific cod fisheries. POSITIVE IMPACTS: The preferred alternative would protect the habitat and individuals of the Steller sea lion species from further incidental by fishing interests in the affected fisheries. The socioeconomic impacts of the preferred alternative would be as limited as possible. NEGATIVE IMPACTS: Conditionally significant effects would occur with respect to the harvest of prey species for Steller sea lion. Economic returns from the affected fisheries would decline by between one and six percent overall; specific regions could suffer from losses of up to 17 percent.

Evidence indicates that both are influenced by global SSTAs. The SSTA modes generating favorable atmospheric conditions for tropical storms to develop are also in favor of a wet rainfall season in the Sahel and Sudan region. The easterly waves over West Africa become tropical storms only if the atmospheric conditions over the Atlantic are favorable. These conditions are responses to SSTAs. In addition to ENSO, a multidecadal trend mode also plays a role. The positive phase of the trend mode features positive loadings in the North Pacific and the North Atlantic, and negative loadings over the three southern oceans. The positive (negative) phases of both modes are associated with increased (reduced) Atlantic tropical storm activity, and with wet (dry) West African monsoon seasons. The SSTAs over the tropical South Atlantic (S-ATL) are related to the rainfall dipole over West Africa, but the influence on tropical storms is not large. Warm (cold) SSTAs over the tropical North Atlantic enhance (suppress) the occurrence of tropical storms, but have little influence on rainfall over West Africa. The most prominent circulation features associated with the positive phases of SSTA modes are enhanced upper-level 200-hPa easterly winds and reduced vertical wind shear in the main development region of the tropical Atlantic, which are well-known features of active Atlantic tropical storm seasons. The associated low-level flow shows enhanced anomalous westerly winds across the Atlantic to Africa. That allows more moisture transport into Africa and, therefore, more rainfall.

AN - 36419025; 9042 AB - PURPOSE: The improvement of 17 miles of Louisiana (LA) 1 in Lafourche Parish, Louisiana is proposed. From Interstate 10 (I-10) at Port Allen to LA 3090 at Port Fourchon, LA 1 is designated as a principal arterial within the National Highway System due to the facilities intermodal link to a major portion of the nation's energy supply. As the only highway in the area, LA 1 is the sole transportation route for workers and supplies entering and existing Port Fourchon and is the only hurricane evacuation route for thousands of residents in south Lafourche Parish. The new facility would be a four-lane, divided, fully controlled access elevated highway on new alignment paralleling existing LA 1 between Louisiana (LA) 3235 west of Golden Meadow and LA 3090 at its intersection with Louisiana 1, north of Port Fourchon. Bridges would span navigable waterways. Access to the facility would be limited to on and off ramps and two-lane connector roads constructed on new location at proposed interchange locations at LA 3235, LA 1 at Leeville, and LA 3090. Four alignment alternatives, including a No Action Alternative, are considered in this draft EIS. The preferred alternative (Line A) Construction of the project could be staged or programmed for discrete construction as funding permits. Estimated cost of the project is $523.2 million. With the exception of the Leeville Lift-Bridge, existing LA 1 would remain in service following completion of the new facility, though administration of the old facility would be transferred to local authorities. POSITIVE IMPACTS: The project would complete the southernmost portion of the principal arterial, connecting the facility to LA 3235, an existing four-lane divided highway west of Golden Meadow. Once completed, a four-lane divided highway facility would be available from LA 3090 north of Port Fourchon to north of Galliano, Louisiana. Emergency response to hazardous materials and oil spills would be enhanced. NEGATIVE IMPACTS: Rights-of-way requirements would result in the displacement of one house, one mobile home, and one business. The project would also displace 5.3 acres of wetlands, 16.34 acres of floodplain, and 0.1 acre of prime farmland soils. Portions of the project corridor are likely to contain archaeological resource sites, and the project rights-of-way would encompass one oil and gas well. Noise levels would exceed federal standards in the vicinity of three sensitive receptors.

If historical environmental records do not exist, other methods must be employed to obtain this information. A well-known geochemical procedure that supplies this type of data is the use of natural radioactive nuclides to "date" the timing of events. Of the many naturally occurring nuclides, (super 210) Pb is the best suited for gauging the timing of episodes in Florida Bay. The age-depth relationships were calculated using the (super 210) Pb method for thirty-five sites within Florida Bay. The ages were independently confirmed by comparing the distribution of known concentrations of atmospherically anthropogenic lead recorded in dated cores to similar data in an annually banded coral. Sediments in the western and northern fringe of Florida Bay are accumulating at nearly equal 0.3 cm/yr, a rate similar to that of sea level rise. In the north-central part of the bay, sediments are accumulating at a faster rate of approximately 1.0 cm/yr. The highest rate, > or =2.0 cm/yr was measured in the northeastern part of the bay on the bank between Pass and Lake Keys. The rapid rate of accumulation in the northeastern part of the bay permits the deciphering of biological and geochemical changes with an accuracy of about two years. In contrast, the intermediate sediment rate in the central part of the bay provides adequate age-depth for relationships deciphering the environmental record of the past 100 years.

Because of its location, between the Shark River Slough (SRS) and the Gulf of Mexico, the Oyster Bay core locality experiences extreme salinity fluctuations due to the interaction of freshwater run-off, precipitation, and marine water inputs. Ostracode population dynamics and isotopic variability over the 20th century are linked to natural and anthropogenic forces that affect the South Florida coastal ecosystem on interannual to decadal time scales. Three ostracode assemblages can be recognized within the 100-year sediment-core record: the first extending from the turn of the century to about 1950; the second, from the early 1950s to the late 1970s; and the third to core recovery in 1995. An abrupt decrease in ostracode abundance, species diversity, and shifts in species dominance occur in the mid-1980s and reflect episodes of environmental stress. Markedly enriched delta (super 18) O values from the ostracode Peratocytheridea setipunctata and the benthic foraminifer Ammonia parkinsoniana typica at this time are concurrent with a major regional drought in South Florida, as well as with documented algal blooms and major die-off of sea grasses in Florida Bay. In addition, the timing of these events is contemporaneous to the onset of the South Florida Water Management District (SFWMD) "Rainfall Plan" and the closing of the Buttonwood canal. Higher ostracode abundance and species richness occurs between thelate-1950s and late-1970s. Stable isotopic data and ostracode assemblage characteristics suggest a period of relative environmental stability and possibly improved water circulation in Whitewater Bay and Oyster Bay. Fluctuations in community structure during this time are more systematic and appear to be temporally correlated to rainfall variability patterns. Water management policies at this time are also discernable from the microfaunal and isotopic record, particularly the Congressionally mandated Monthly Minimum Allocation Plan of water supply to SRS. Before 1950, hurricane events and their effects are the major cause for immediate modifications within the ostracode community, though our data show that ostracode populations are capable of rapid recovery. Over the complete record of the last century, the effects of water management practices can be assessed from information embedded in the ostracode record. Nevertheless, the effects of natural climatic variability in Oyster Bay appear to outweigh the impact of anthropogenic forces.

The SWIR falls at the ultraslow end of the spreading spectrum and represents the low magma budget end-member of mid-ocean ridges. The section surveyed is exceptional because for most of its length, only partially serpentinized peridotite and scattered basalt is exposed on the seafloor. This makes it an ideal area to study ultramafic-hosted hydrothermal systems. The hydrothermal deposits consist of concretions of opaline silica, basalt breccias cemented by smectite and Mn-oxides (birnessite), and partially oxidized massive sulfides. Preliminary XRD analyses indicate a range of silica polymorphs in the deposits from opal-A to opal-CT to quartz. Sepiolite, a rare Mg-rich clay mineral in the deep sea, has also been identified that likely formed during seawater/ultramafic rock interaction. We believe the massive sulfides represent a fossil site of high-temperature discrete venting. A plume-mapping program was conducted concurrently that collected temperature, pressure, and light back scattering data from 67 lowerings. Ten casts produced anomalous profiles characterized by sudden deviations from background values. Together, the recovery of massive sulfides and plume data indicate that high-temperature hydrothermal convection may exist in the absence of volcanic activity at slow-spreading ridges and that it may be taking place at present. This is remarkable because of the extremely low magma budget and hence minimal magmatic heat input into the system. Instead, "non-magmatic" heat sources (e.g., conductive heat loss and exothermic mineral reactions) might be the driving force of these systems and long-lived normal faults along the rift valley walls may provide pathways along which deeply circulating fluids rise to the seafloor. Our preliminary data suggest that hydrothermal input from ultraslow spreading ridges might be larger than expected. Determining the driving forces and structural controls of hydrothermal systems at ultraslow spreading ridges and the frequency of active hydrothermal sites will be important in determining their role in lithospheric accretion and global geochemical budgets.

The first study is based on living (Rose Bengal stained) specimens of Hoeglundina elegans collected over a one-year interval at a 3010 m site south of Nantucket Island. Carbon isotopic data taken over a 10-month interval (March, May, July, October, 1996, January, 1997) were compared with an 11.5-month time-series of organic carbon from a sediment trap to assess the effect of variation of organic carbon flux. The delta (super 13) C data show a 0.3 per mil lower mean value following an organic carbon maximum resulting from a spring phytoplankton bloom. This change is suggested to be due to the presence of a phytodetritus layer on the seafloor and the subsequent depletion of delta (super 13) C in the porewaters within the phytodetritus. In a related study, the delta (super 13) C of Holocene benthic foraminifera from 45 core tops from 0-62 degrees N in the Atlantic were studied and compared with satellite-derived primary productivity and seasonality. The delta (super 13) C of Epistominella exigua show a approximately 1 per mil decrease over 60 degrees of latitude, with the data correlating with overlying primary productivity, organic carbon flux, and seasonality. This significant depletion of delta (super 13) C of E. exigua is attributed to the seasonal presence of phytodetritus over a large portion of the North Atlantic. No relationships were found between the delta (super 13) C of Planulina wuellerstorfi and primary productivity, organic carbon flux, or seasonality. These observations demonstrate that (i) variation in the spatial and temporal pattern of organic carbon affects the delta (super 13) C of certain deep-sea taxa, (ii) carbon isotopic data of E. exigua may be potentially useful in reconstructing organic carbon flux and primary productivity, and (iii) the delta (super 13) C of P. wuellerstorfi in the North Atlantic is unaffected by organic carbon flux and reflects the delta (super 13) C of the bottom waters.

New technologies and protocols for data management promise to make the coming decade even more exciting in terms of the way scientific data are shared electronically. NOAA's World Data Center for Paleoclimatology has participated in this data revolution, archiving and distributing data at an exponentially increasing rate, and serving a diverse user community that ranges from scientists to students to policy makers. Several factors contributed to the Center's early success: an emphasis on national and international partners to identify needs and priorities in data management, and the formation of data cooperatives consisting of small teams of scientists who volunteered their time to develop or refine data sets. The co-ops have played a key role in producing high quality, discipline-specific databases by keeping the decisions and quality control in the hands of experts who are most familiar with specific types of data. A third factor was the quick adoption of internationally recognized protocols for data management, such as the policy of free and open access to scientific data, and the use of standard data types and formats for data archive and exchange. One of the challenges facing the program (and most other data centers) today is how to make it easier for the users to integrate different types of data. From a practical perspective, integration involves providing data in formats that are intuitive and easy to use. From the perspective of content, the goal is to provide sufficient information so that the data can be used successfully by scientists from different disciplines, or with specific requirements, such as GIS users who require spatial reference information. Several different strategies and approaches used by the Center to make data easier to integrate will be presented.

Actively eroding coastal bluffs along the western shore of the Chesapeake Bay provide a key for understanding the centennial-scale development of stable slopes from eroding bluff faces. The Calvert Cliffs are composed of sandy silts, silty sands, and clayey silts of Miocene-age. Active wave erosion at the bluff toes encourages rapid sloughing from bluff faces and maintains slope angles of 70-80 degrees and relatively constant bluff-retreat rates. Naturally stabilized slopes are preserved as a fossil bluff line inland from a prograding cuspate foreland at Cove Point. The foreland is migrating southward at a rate of ca. 1.5 m/yr. As it moves south, it progressively protects bluffs from wave action as new beaches are deposited at their toes. Wave erosion is reinitiated at the northern end of the complex as the landform passes. An incremental record of slope change is preserved along the fossil bluff line. 14C dating of swales between beach ridges shows the complex to span 1700 years of progressive migration history. We hypothesized that slopes would change from steep, eroding faces to low-angle slopes covered with vegetation and sought to document the rate of change. Our team measured slope angles at intervals along the fossil bluff line and dated profiles by interpolating 14C ages of adjacent beach ridges. There was no progressive decrease in slope with age. All slopes along the fossil bluff line were 30-40 degrees with a mean of 35 degrees . Constancy in slope angle suggests that steep, actively eroding bluffs were quickly changed to stable slopes by landslides and slumping once they were protected. Given the accuracy of our age control, we conclude that the time required to attain a stable slope under natural processes is less than one century. This indicates that once toe erosion is ended (naturally or through engineering) slopes are reduced to 35 degrees over a period of decades and not centuries.

In addition, some teleconnections have been shown between Atlantic SST and Pacific SST anomalies. Major climate indices in the Atlantic includes the AMO (Atlantic Multidecadal Oscillation), NAO (North Atlantic Oscillation), the NATL (North sub-tropical Atlantic Oscillation), and the SATL (South sub-topical Atlantic Oscillation). The Cape Verde Islands are within the zone of highest correlation (r>0.80) for the NATL. These dry, volcanic islands lie off the west African coast at about 16 degrees N, and four species of zooxanthellate scleractinia are present. Of these corals, the species Siderastrea radians forms slabs of upto 24 cms in thickness. Combined with a relatively low rate of extension the specimens are between 50 and 200 years in age. We have collected several colonies from Cape Verde which have been slabbed, x-rayed, and sampled for delta (super 18) O, delta (super 13) C, Sr/Ca, Ba/Ca, and fluorescence. Sclerochronology dates one of these corals back as far as 1938 with an accuracy of + or -0.5 yr. During the time frame from 1938-1999, the oxygen isotopic composition show a strong correlation with the most recent drought in the Sahel region of Africa (11 degrees -18 degrees N) which began about 1970. This Cape Verde coral also shows a negative correlation within the same period with the NATL and a positive correlation within that period with Sahel rainfall and the AMO. The history of the this particular coral is too short to accurately elucidate such signals as the 65-80 year cycle of the AMO, but ongoing investigation with older specimens promises to show other connections between stable isotope records in Cape Verde corals and tropical Atlantic SST and nearby terrestrial climates.

Specifically, performance comparisons are made within an automated multicriteria calibration framework to evaluate the benefit of "spatial distribution" of the model input (precipitation), structural components (soil moisture and streamflow routing computations), and surface characteristics (parameters). A comparison of these results is made with those obtained through manual calibration. Results indicate that for the study watershed, there are performance improvements associated with semidistributed model applications when the watershed is partitioned into three subwatersheds; however, no additional benefit is gained from increasing the number of subwatersheds from three to eight. Improvements in model performance are demonstrably related to the spatial distribution of the model input and streamflow routing. Surprisingly, there is no improvement associated with the distribution of the surface characteristics (model parameters). Copyright 2001 by the American Geophysical Union.

The results indicate that the SW monsoon varied at about 100 kyr and 400 kyr periodicities within Earth's eccentricity domain (Milankovitch range) over the past 2 million years. Wavelet transform analysis reveals the non-stationary nature of monsoon upwelling over this interval. The amplitude of the 400 kyr cycle in the U. proboscidea time series began to increase at approximately 900 kyrs as has also been observed in few recent studies. We do not see a strong relation between eccentricity highs and intense summer monsoons over the studied interval.

Eight patches of larvae were tagged with satellite-tracked drifters and followed for periods of 1 to 11 d. We conducted daily plankton tows within a 3.2 km super(2) area circumscribing each drifter. This allowed us to verify that each drifter remained within a patch. Trajectories of the patches were assessed in relation to physical data (salinity, temperature, winds, and river discharge) and compared to trajectories predicted by a 2 dimensional mathematical model. Analysis of CTD data indicated that 3 patches were initially tagged in the coastal plume emanating from Delaware Bay, while 5 patches were initially tagged in shelf water adjacent to the plume. Patches occurring in plume waters traveled farther down-shelf (southward) than those in adjacent shelf waters. Winds modified this along-shelf transport. Specifically, upwelling-favorable (northward) winds mixed larvae offshore and out of the coastal plume. Downwelling-favorable (southward) winds drove patches of larvae across the continental shelf and toward the coast. Trajectories were simulated well by the mathematical model. As river discharge diminished in the late summer, the effect of winds (relative to buoyancy forcing) on larval transport increased. This shift in the dominant forcing mechanism was demonstrated both by the trajectories of the tagged larval patches and by predictions from the mathematical model.

Light absorption by particles emitted from low-technology coal combustion has exhibited a strong spectral dependence. I investigate various explanations for this phenomenon and conclude that a spectrally dependent imaginary refractive index is the most plausible. Following previous work on the structure of amorphous carbon, I propose that both the magnitude and spectral dependence of light absorption are controlled by the size of graphitic clusters within the material, and can be described using the optical band-gap theory. This hypothesis is an alternative to the current measurement divisions of light-absorbing "black carbon" and non-absorbing "organic carbon," and offers an explanation for preferential absorption at blue wavelengths that may extend to ultraviolet wavelengths.

In such systems, development of mechanisms to allow resource users to acknowledge interdependence and to engage in negotiations and agreements becomes necessary. Recently, after a decade of deliberations and environmental assessments, the Glen Canyon Dam Adaptive Management Program (GCDAMP) was established to monitor and analyze the effects of dam operations on the Grand Canyon ecosystem and recommend adjustments intended to preserve and enhance downstream physical, cultural and environmental values. The Glen Canyon Dam effectively separates the Colorado into its lower and upper basins. Dam operations and adaptive management decisions are strongly influenced by variations in regional climate. This paper focuses on the management of extreme climatic events within the Glen and Grand Canyon Region of the Colorado River. It illustrates how past events (both societal and physical) condition management flexibility and receptivity to new information. The types of climatic information and their appropriate entry points in the annual cycle of information gathering and decision-making (the 'hydro-climatic decision calendar') for dam operations and the adaptive management program are identified. The study then describes how the recently implemented program, lessons from past events, and new climate information on the Colorado River Basin, facilitated responses during the major El Nino Southern Oscillation (ENSO) event of 1997-1998. Recommendations are made for engaging researchers and practitioners in the effective use of climatic information in similar settings where the decision stakes are complex and the system uncertainty is large.

As a result of these radioactive discharges, about 28,000 local residents were exposed to ionizing radiation, and some of them received relatively high doses. Internal exposure of the population residing at the Middle and Lower Techa riverside was mostly from super(90)Sr deposited in bone and tooth tissues. In order to reconstruct radiation doses to this population group, a study of 35 teeth extracted from local residents was carried out using electron paramagnetic resonance measurements. A total of 73 samples from these 35 teeth (tooth enamel, 33; crown dentin, 20; and root dentin, 20) were prepared and measured with electron paramagnetic resonance. The study revealed high doses (up to 15 Gy) absorbed in tooth enamel of the individuals born during 1945-1949, which was attributed to very high local super(90)Sr concentration in tooth enamel of this particular age group in the population. The analysis presented here takes into account (a) the time courses both of the release/intake of super(90)Sr and of the tooth formation, and (b) expected variations in measured absorbed doses due to differing geometric sizes of tooth structures. This methodology enables a more consistent picture to be developed of the super(90)Sr intake by the Middle and Lower Techa riverside population, based on electron paramagnetic resonance tooth dosimetry.

The mean density of B. cederstroemii at the offshore station was generally highest in July-September (145-914 m super(-2)) and at the nearshore station in October-November (168-1625 m super(-2)). In 1995 and 1998, density was also high at the offshore station in November (211-284 m super(-2)). Fish predation may limit B. cederstroemii in nearshore regions in the summer. The maximum annual densities of B. cederstroemii for 1995-98 were generally similar to those reported from the late 1980s, when the species arrived in Lake Michigan. Body size increased rapidly each year to a maximum in August. Thereafter, body size declined and converged for stage-2 and 3 individuals, suggesting food scarcity or size-selective fish predation was affecting large individuals. Most reproduction occurred asexually (90%), and by stage 2 or 3 females (99%). Asexual brood size was highest when B. cederstroemii first appeared each year, and decreased in August, when larger neonates were produced. There appeared to be differences in reproductive mode for stage 2 and 3 females, with a higher percentage of stage 2 females reproducing sexually.

Two case studies and their restoration approaches are presented. The grounding of the M/V FORTUNA REEFER on the reefs of Mona Island, Puerto Rico resulted in approximately 2.75 hectares of coral injury. The grounding resulted in a discreet impact zone, but the salvage effort increased the injury to many times the size of the grounding area. Emergency restoration efforts at the site entailed the use of stainless steel wire and nails to reattach detached and broken colonies of Acropora palmata. A restoration status report is provided. A phosphate industry spill of approximately 189 - 211 million liters (50-56 million gallons) of process water containing phosphoric acid (pH 2) resulted in the instantaneous kill of over 1.3 million freshwater and marine fish in the Alafia River and Tampa Bay, Florida. The fish injury, including both the direct kill and the lost future somatic growth, was estimated at 64,892 kilograms of biomass lost. In addition, the spill injured approximately 377 acres of freshwater wetlands and contributed to nutrient loading in Tampa Bay. Restoration or creation of emergent estuarine habitat and/or reef creation are being considered to compensate for the fish injuries.

Hens were subcutaneously injected every 4 days with a mixture of the above chemicals. One group of five eggs was removed from the incubator at each of 9, 14, and 19 days of incubation; dissected into three compartments (embryo, chorioallantoic membrane, and yolk + albumin); weighed; frozen; and then later analyzed for the dosing chemicals. Through 19 days of development (90% of incubation), greater than 70% of the total chemical mass in the whole egg remained within the yolk + albumin, whereas, depending on the chemical, 17% to 30% was absorbed by the embryo and 0.2% to 9% was transported into the chorioallantoic membrane. As a percentage of total PCB mass within the respective compartment, PCB 105 composition in the embryo and chorioallantoic membrane decreased significantly throughout development while PCB 156 and 189 composition increased significantly throughout development. Though endosulfan composition within any of the compartments was highly variable, it did not change significantly during development. The results of this study indicate that the majority of avian chick exposure to contaminants occurs posthatch as the chick continues to utilize the residual yolk.

For watersheds impacted by acid-rock drainage (ARD), low suspended matter concentrations are more likely to be found when acid rock drainage travels through soils because much of the Fe and Al that could form adsorbing surfaces is retained within the soils. In the absence of additional sources of solid substrates, metals can be transported great distances downstream once this Fe- and Al-poor ARD seeps into surface waters. In a 46-km backwater reach of the Coeur d'Alene River, it appears that biological activity increased pH and provided the organic matter solid substrate which removed approximately 50% of the Zn and Cd. Zn removal was partially reversible as pH decreased. These observations reinforce the concept that both inorganic and organic carbon chemistry must be measured if significant advances in our understanding of the attenuation of Zn and Cd from ARD sources are to be made.

AN - 36415448; 9021 AB - PURPOSE: The construction of a two-lane highway and bridge within a minimum right-of-way of 66 feet to connect the existing road system from the intersection of South Carolina Route (SC) 33 and SR 267 to Secondary Road (Road S-) 52 or Road S-26 in Calhoun, Clarendon, and Sumter counties, South Carolina is proposed. The facility would cross Lake Marion in the vicinity of an existing CSX Railroad bridge near Lone Star and Timini and would consist of a 47-foot wide, 2.8-mile-long bridge. The bridge would extend to the limits of the lake's 100-year floodplain. Three alternatives, including a No Action Alternative (Alternative 3), are considered in this draft EIS. Alternative 1 would extend 9.6 miles from a point west of Lone Star at the intersection of SC 33 and SC 267, crossing through cropland and pasture, upland mixed forest, upland pine, forested and non-forested wetlands, and open water before terminating northwest of Rimini at Road S-52. The centerline would lie approximately 180 feet northwest and upstream of the centerline of the CSX Railroad lake crossing. Alternative 2 would extend 6.7 miles from a point east of Lone Star at the intersection of Road S-265 and SC 267, crossing through the lake southeast of the railroad and terminating east of Rimini into Road S-26. The centerline of Alternative 2 would lie approximately 140 feet east and downstream of the centerline of the CSX Railroad lake crossing. Construction costs of alternatives 1 and 2 are estimated at $83 million and $73 million, respectively. POSITIVE IMPACTS: The new bridge would shorten travel times between locations in Lone Star and Rimini significantly. Access to industrial employment centers, health care facilities, and institutions providing higher education opportunities would be improved as a result. Travel time for through traffic would also be improved. NEGATIVE IMPACTS: Rights-of-way requirements for Alternative 1 would require acquisition of 52.8 acres via fee simple purchases and 48.5 acres via easements. As a result, the project would displace two residential units and one business, 5.7 acres of wetlands, 39.6 acres of farmland. Noise levels in excess of federal standards would occur in the vicinity of two sensitive receptor sites. One archaeological site would be affected. Four sites potentially containing hazardous wastes would be encountered during construction. Rights-of-way requirements for Alternative 2 would require acquisition of 30.7 acres via fee simple purchases and 50.3 acres via easements. As a result, the project would displace 2.3 acres of wetlands and 21.9 acres of farmland. Two sites potentially containing hazardous wastes would be encountered during construction. Under either alternative, impacts to minorities would be disproportionate, and two recreational resources, Palmetto Trail and Lake Marion, would be affected.

Preparation date: October 19, 2001 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - GOAT CANYON ENHANCEMENT PROJECT, CITY AND COUNTY OF SAN DIEGO, CALIFORNIA. AN - 36415814; 9005 AB - PURPOSE: The implementation of an ecosystem restoration plan for Goat Canyon within the city and county of San Diego, California is proposed. The project site is located in the extreme southwestern corner of the United States. Goat Canyon is located in the far western portion of the greater Tijuana River watershed within both the United States and Mexico. The project site encompasses the creek and the watershed located north of the border, immediately west of Spooner's Mesa in the Tijuana River Valley. Recent rapid and primarily unplanned development south of the Mexican border over the last 30 years has resulted in a great deal of erosion and sediment deposition in the canyon, which is characterized by steep slopes and sandy soil. The hydrologic, hydraulic, and sediment transport characteristics of the creek have been altered significantly, jeopardizing the health of associated marshes. Five alternatives, including a No Action Alternative are considered in this draft EIS. The preferred alternative (Alternative D) would consist of an in-canyon diversion structure that transitions to a flow-through sedimentation basin system consisting of two basins. This alternative would also include the construction of access roads and staging areas, construction of a visual screening berm adjacent to Monument Road, improvements to Monument Road, and creation of wetland habitat. Two variations for the elevation and widening of Monument Road and two variations for the location of a multipurpose trail have resulted in a combination of four options for the road and trail components of the alternative. The diversion structure would divert large flows and sediment from the existing channel into the sedimentation basin system as well as supply low flows to the existing channel and trap large debris. The diversion structure would be created by constructing a berm approximately 20 feet above the flowline of the existing channel. Earthwork would be limited to approximately 10,400 cubic yards of cut and 1,700 cubic yards of fill using native soils for the berm and 3,960 cubic yards of rock for the berm and aprons. Riprap erosion protection would be placed downstream of the low-flow structure as well as at the transition from the diversion structure to the basin system. The two basins would be located parallel to and east of the existing channel immediately downstream of the diversion structure. Earthwork for the basin system would include 186,800 cubic yards of excavation and 43,100 cubic yards of fill. Approximately 7.900 cubic yards of rock would be necessary for bank protection upstream and downstream of the outlet weir structures. Construction cost estimates range from $4.7 million to $4.8 million, depending on the road/trail option selected. Estimated maintenance and operation costs, including the cost of annual excavation and disposal of 42,350 cubic yards of sediment and site monitoring, are expected to be $553,000 if the excavated material has no offsite value and $175,000 if the material has offsite value. POSITIVE IMPACTS: By trapping sediment in the basins, the project would reverse conditions that result in the loss of soil within the canyon and damage to wetlands within and downstream of the canyon. The composition and distribution of native habitat communities along the creek and on the alluvial fan would be restored, as would the morphology of the creek. NEGATIVE IMPACTS: Approximately 0.9 acres would be cleared of vegetation and grubbed for construction of the diversion structure. The limits of construction around the structure would add approximately 0.6 acres to this area, for a total of 1.5 acres. The basin system would displace 22 acres. An additional 5.3 acres would be cleared and grubbed for staging area purposes. Project equipment would emit high levels of noise, and project activities could temporarily disrupt recreational uses of the canyon.

Using this technique, we could quantify the force required to separate antigen to antibody bonds. At very low surface density of antigen, we were able to detect the single antigen to antibody binding. The force required to break the antigen-antibody bonds and pull the microsphere off the surface was shown to increase monotonically with increasing surface density of antigens. Using the force determination as a transducer, we were able to detect concentrations of free antigens in solution as small as 10 super(-15) mol/L in a competitive binding assay.

I. Exact and approximate analytical results. AN - 85362161; pmid-11681370 AB - In the upper tens of meters of ocean bottom, unconsolidated marine sediments consisting of clay, silt, or fine sand with high porosity are "almost incompressible" in the sense that the shear wave velocity is much smaller than the compressional wave velocity. The shear velocity has very large gradients close to the ocean floor leading to strong coupling of compressional and shear waves in such "soft" sediments. The weak compressibility opens an avenue for developing a theory of elastic wave propagation in continuously stratified soft sediments that fully accounts for the coupling. Elastic waves in soft sediments consist of "fast" waves propagating with velocities close to the compressional velocity and "slow" waves propagating with velocities on the order of the shear velocity. For the slow waves, the theory predicts the existence of surface waves at the ocean-sediment boundary. In the important special case of the power-law depth-dependence of shear rigidity, phase and group velocities of the interface waves are shown to scale as a certain power of frequency. An explicit, exact solution was obtained for the surface waves in sediments characterized by constant density and a linear increase of shear rigidity with depth, that is, for the case of shear speed proportional to the square root of the depth below the sediment-water interface. Asymptotic and perturbation techniques were used to extend the result to more general environments. Theoretical dispersion relations agreed well with numerical simulations and available experimental data and, as demonstrated in a companion paper [D. M. F. Chapman and O. A. Godin, J. Acoust. Soc. Am 110, 1908 (2001)] led to a simple and robust inversion of interface wave travel times for shear velocity profiles in the sediment.

AN - 72227410; 11677182 AB - Pfiesteria piscicida Steidinger & Burkholder is a toxic dinoflagellate that leads to fish and human toxicity. It produces a bioactive substance that leads to cytotoxicity of GH4C1 rat pituitary cells. Extracellular adenosine 5'-triphosphate (ATP) acting on P2X7 purinergic receptors induces the formation of a nonselective cation channel, causing elevation of the cytosolic free calcium followed by a characteristic permeabilization of the cell to progressively larger ions and subsequent cell lysis. We investigated whether GH4C1 rat pituitary cells express functional P2X7 receptors, and if so, are they activated by a bioactive substance isolated from toxic P. piscicida cultures. We tested the selective agonist 2'-3'-O-(benzoyl-4-benzoyl)-ATP (BzATP) and antagonists piridoxalphosphate-6-azophenyl-2'-4'-disulfonic acid (PPADS) and oxidized-ATP (oxATP) using elevated cytosolic free calcium in Fura-2 loaded cells, and induced permeability of these cells to the fluorescent dye YO-PRO-1 as end points. We demonstrated that in GH4C1 cells, BzATP induces both the elevation of cytosolic free calcium and the permeabilization of the cell membrane. ATP-induced membrane permeabilization was inhibited by PPADS reversibly and by oxATP irreversibly. The putative Pfiesteria toxin (pPfTx) also elevated cytosolic free calcium in Fura-2 in GH4C1 cells and increased the permeability to YO-PRO-1 in a manner inhibited fully by oxATP. This study indicates that GH4C1 cells express a purinoceptor with characteristics consistent with the P2X7 subtype, and that pPfTx mimics the kinetics of cell permeabilization by ATP.

AN - 72226133; 11677179 AB - Long-term monitoring of water quality, fish health, and plankton communities in susceptible bodies of water is crucial to identify the environmental factors that contribute to outbreaks of toxic Pfiesteria complex (TPC) species. In the aftermath of the 1997 toxic Pfiesteria outbreaks in North Carolina and Maryland, federal and several state agencies agreed that there was a need to standardize monitoring protocols. The National Oceanic & Atmospheric Administration convened two workshops that brought together state, federal, and academic resource managers and scientific experts to a) seek consensus on responding to and monitoring potential toxic Pfiesteria outbreaks; b) recommend standard parameters and protocols to characterize water quality, fish health, and plankton at historical event sites and potentially susceptible sites; and c) discuss options for integrating monitoring data sets from different states into regional and national assessments. Workshop recommendations included the development of a three-tiered TPC monitoring strategy: Tier 1, rapid event response; Tier 2, comprehensive assessment; and Tier 3, routine monitoring. These tiers correspond to varying levels of water quality, fish health, and plankton monitoring frequency and intensity. Under the strategy, sites are prioritized, depending upon their history and susceptibility to TPC events, and assigned an appropriate level of monitoring activity. Participants also agreed upon a suite of water quality parameters that should be monitored. These recommendations provide guidance to state and federal agencies conducting rapid-response and assessment activities at sites of suspected toxic Pfiesteria outbreaks, as well as to states that are developing such monitoring programs for the first time.

(Prymnesiophyceae): increased sensitivity after long-term, low-level population exposure. AN - 72187590; 11596756 AB - Phytoplankton are potentially more at risk to the adverse effects of herbicides than many other organisms in estuarine ecosystems. The focus of this study was to characterize the toxicity of a widely used herbicide, atrazine, to a single species of phytoplankton. The nanoplankter Pavlova sp. was grown under controlled laboratory conditions and was used to elucidate short-term, high-level population effects of atrazine. Secondly, a long-term, multigenerational population exposure was performed with a low level of atrazine followed by an additional short-term, high-level exposure on the same population with no recovery period. The 96-h growth rate of 50% effective concentration (EC50) for Pavlova sp. was 147 [microg/L (95% CI = 116.4-178.7 microg/L). Long-term exposure at 20 [microg/L for four (batch culture) growth cycles (approximately 20 generations) had no significant effect on the growth rate of Pavlova sp. except during the fourth growth cycle. However, a subsequent short-term, high-level 96-h exposure inoculated from the long-term, low-level exposed population showed increased sensitivity to atrazine (96-h growth rate EC50 = 96.0 microg/L, 95% CI = 90.2-103.7 microg/L). Multigenerational exposure to atrazine appeared to render phytoplankton significantly more sensitive (35%) to atrazine effects. Given the documented persistence of atrazine in surface waters, long-term exposure to low levels of atrazine without recovery may lead to shifts in species sensitivity and potential alterations in phytoplankton population dynamics.

Beginning with SeaWiFS (Sea Wide Field-of-view Sensor) in September 1997, these sensors provide coverage every 1 to 2 days with 1-km pixel view at nadir. Atmospheric correction algorithms designed for the coastal zone combined with regional chlorophyll algorithms can provide good and reproducible estimates of chlorophyll, providing the means of monitoring various algal blooms. Harmful algal blooms (HABs) caused by Karenia brevis in the Gulf of Mexico are particularly amenable to remote observation. The Gulf of Mexico has relatively clear water and K. brevis, in bloom conditions, tends to produce a major portion of the phytoplankton biomass. A monitoring program has begun in the Gulf of Mexico that integrates field data from state monitoring programs with satellite imagery, providing an improved capability for the monitoring of K. brevis blooms.

Six recognized human poisoning syndromes resulting from algal toxins (paralytic, neurotoxic, amnesic, diarrhetic shellfish poisonings, ciguatera fish poisoning, and putative estuary associated syndrome) impact human health through consumption of contaminated seafood, direct contact with bloom water, or inhalation of aerosolized toxin. Thorough health risk assessment for the variety of algal toxins is hampered to varying degrees because either the toxin has not been identified or indicators for exposure and effects remain poorly defined. Predicting the occurrence and determining the impacts of harmful algal blooms in coastal ecosystems are the two major ecological risk assessment needs. In the former case, the hazard is the suite of conditions that trigger bloom initiation, magnify bloom intensity or support bloom longevity, whereas in the latter case, the hazard is the algal toxin. In both cases, indicators (of triggering mechanisms, exposure, and effects) are better defined for some HAB species and toxins than others, but are by no means complete.

N1 - Last updated - 2011-12-13 ER - TY - JOUR T1 - Use of Metabolic Inhibitors to Characterize Ecological Interactions in an Estuarine Microbial Food Web AN - 18385092; 5375286 AB - Understanding microbial food web dynamics is complicated by the multitude of competitive or interdependent trophic interactions involved in material and energy flow. Metabolic inhibitors can be used to gain information on the relative importance of trophic pathways by uncoupling selected microbial components and examining the net effect on ecosystem structure and function. A eukaryotic growth inhibitor (cycloheximide), a prokaryotic growth inhibitor (antibiotic mixture), and an inhibitor of photosynthesis (DCMU) were used to examine the trophodynamics of microbial communities from the tidal creek in North Inlet, a salt marsh estuary near Georgetown, South Carolina. Natural microbial communities were collected in the spring, summer, and fall after colonization onto polyurethane foam substrates deployed in the tidal creek. Bacterial abundance and productivity, heterotrophic ciliate and flagellate abundance, and phototrophic productivity, biomass, and biovolume were measured at five time points after inhibitor additions. The trophic responses of the estuarine microbial food web to metabolic inhibitors varied with season. In the summer, a close interdependency among phototrophs, bacteria, and protozoa was indicated, and the important influence of microzooplanktonic nutrient recycling was evident (i.e., a positive feedback loop). In the fall, phototroph and bacteria interactions were competitive rather than interdependent, and grazer nutrient regeneration did not appear to be an important regulatory factor for bacterial or phototrophic activities. The results indicate a seasonal shift in microbial food web structure and function in North Inlet, from a summer community characterized by microbial loop dynamics to a more linear trophic system in the fall. This study stresses the important role of microbial loops in driving primary and secondary production in estuaries such as North Inlet that are tidally dominated by fluctuations in nutrient supply and a summer phytoplankton bloom.

Four distinct bioassay systems were used to monitor bioactivity of the P. piscicida extracts, including a high throughput cell cytotoxicity assay and a reporter gene assay as well as assays using brine shrimp and fish. Using these bioassays to guide fractionation, we have isolated two distinct, active fractions from Pfiesteria culture medium and cell mass extracts on the basis of their solubility characteristics. We have identified and characterized a bioactive lipophilic substance from Pfiesteria-derived extracts as di(2-ethylhexyl)phthalate, a commonly used plasticizer. The source of this typically man-made substance has been identified as originating from Instant Ocean (Aquarium Systems, Mentor, OH, USA), a commercially available seawater salt mixture used to prepare our mass culture growth medium. We have developed chromatographic methodology to isolate a bioactive polar compound isolated from extracts of Pfiesteria culture and presently report the characterization of the activity of this substance. The molecular structural analysis of the polar active component(s) using mass spectrometry and nuclear magnetic resonance spectroscopy is currently under way.

Analysis of 2 years worth of data revealed that the response is greatest in the north of Brazil where aerosol optical depth is smallest, and tends to decrease as one moves southward, and as aerosol optical depth increases. Saturation in this response occurs at an aerosol optical depth of 0.8 in 1987 and 0.4 in 1995. To explore the reasons for this, a framework is developed in which the satellite-measured response can be compared to simple analytical models of this response and to numerical models of smoke aerosol-cloud interaction. Three types of response are identified: (1) cloud droplet concentrations increase with increasing aerosol loading, followed by saturation in the response at high concentrations; (2) as in type 1, followed by increasing droplet concentrations with further increases in aerosol loading. This increase in droplet concentration is due to the suppression of supersaturation by abundant large particles, which prevents the activation of smaller particles. This enables renewed activation of larger particles when smoke loadings exceed some threshold; (3) as in type 1, followed by a decrease in droplet number concentrations with increasing aerosol loading as intense competition for vapor evaporates the smaller droplets. The latter implies an unexpected increase in drop size with increasing smoke loading. The conditions under which each of these responses are expected to occur are discussed. It is shown that although to first-order smoke optical depth is a good proxy for aerosol indirect forcing, under some conditions the size distribution and hygroscopicity can be important factors. We find no-evidence that indirect forcing depends on precipitable water vapor. JF - Journal of Geophysical Research. D.

We investigated the substrate specificity and excision kinetics of this DNA glycosylase for bases in DNA that have been damaged by free radicals. Two different DNA substrates were prepared by gamma -irradiation of DNA solutions under N sub(2)O or air, such that they contained a multiplicity of modified bases. Although previous studies on the substrate specificity of Nei had demonstrated activity on several pyrimidine derivatives, this present study demonstrates excision of additional pyrimidine derivatives and a purine-derived lesion, 4,6-diamino-5-formamidopyrimidine, from DNA containing multiple modified bases. Excision was dependent on enzyme concentration, incubation time, and substrate concentration, and followed Michaelis-Menten kinetics. The kinetic parameters also depended on the identity of the individual modified base being removed. Substrates and excision kinetics of Nei and a naturally arising mutant form involving Leu-90 arrow right Ser (L90S-Nei) were compared to those of Escherichia coli endonuclease III (Nth), which had previously been determined under experimental conditions similar to those in this study. This comparison showed that Nei and Nth significantly differ from each other in terms of excision rates, although they have common substrates. The present work extends the substrate specificity of Nei and shows the effect of a single mutation in the nei gene on the specificity of Nei.

The large size of the water drops produced by fire sprinklers, and the relatively large coverage area of the spray, present significant challenges when attempting to characterize these sprays. These difficulties are especially relevant when using PDI because large drops and large coverage areas may result in attenuation of the transmitting laser beams. For the fire sprinkler investigated, it was determined that attenuation of the laser beam resulted in over-counting of drops due to burst splitting, a situation in which the Doppler signals from single drops are misinterpreted as being due to multiple drops. This effect was minimized by carefully choosing the operating conditions of the PDI processing electronics. PIV measurements provide velocity profiles that can be used as input for fire dynamics simulations to predict the effect of sprinkler sprays on fires. The results from the PIV measurements show good agreement with the velocity measurements obtained from PDI in the core of the spray, but poorer agreement along the sprinkler axis. The discrepancy was attributed to recirculation zones present in the experimental facility and possible biasing of the PIV measurements towards the larger drops.

Sighting data collected during seven summer (1990, 1991, 1993, and 1995-1998) shipboard surveys were analyzed using a geographic information system to determine habitat use based on bathymetric and oceanographic features. Although sighting rates were lower for beaked whales, both taxa occupied similar habitats. Beaked whales were concentrated at the colder shelf edge, whereas sperm whales were associated with warmer off-shelf water. Mean sighting rates for both taxa were higher in canyon features, but only beaked whale sighting rates were significantly different between canyon and non-canyon habitat (Wilcoxon signed rank test P = 0.007). Within the shared habitat, the two taxa were separated at fine-scale based on oceanographic features.

AN - 18230010; 5296511 AB - Dead gray whales (Eschrichtius robustus) were reported along the North American coast, from Baja California, Mexico, to Alaska in record numbers in 1999 and 2000. A total of 273 whale carcasses were reported for the 1999 calendar year, with an unofficial tally of 361 in 2000. What is killing all these whales? Speculation usually focuses on starvation, disease, or anthropogenic impacts (e.g., pollution, vessel strikes, etc.), or some synergistic combination of the three. In whatever combination, the response of gray whales to these or other factors may simply indicate that the Eastern North Pacific (ENP) population is reaching environmental carrying capacity (K). But even if gray whales are at or near K, why are they hitting this hypothetical boundary so hard?.

Critical questions regarding the movements, behavior, and exchange between subpopulations of baleen whales remain unanswered. Satellite telemetry has proven to be a powerful tool for collecting data on migrations, winter distribution, and key behavioral or physiological parameters of Odontocetes (e.g., Heide-Joergensen et al., in press; Read and Westgate 1998). As a result, satellite telemetry has become an attractive method for studying movement of baleen whales (e.g., Mate et al. 1997, 1999). Several techniques have been used to instrument baleen whales including crossbow, jabstick, and shotgun. Although these techniques have proven to be successful, they suffer from limitations in the range at which the instruments can be deployed (crossbow and jabstick, <10 m, e.g., Mate et al. 2000) and the degree of damage to the transmitter from the impact of hitting the whale (shotgun). This manuscript describes the Air Rocket Transmitter System (ARTS), an air gun developed specifically for remote deployment of satellite and radio tags on baleen whales. It also documents the use of the ARTS to successfully track a blue whale in the North Atlantic.

Sensitivity tests indicate that soil moisture and the coverage and thickness of green vegetation [as manifested by the values of fractional green vegetation coverage (fVEG) and leaf area index (LAI)] have a large effect on the magnitudes of surface sensible heat fluxes. The combined influence of LAI and fVEG is larger than the influence of soil moisture on the partitioning of the surface energy budget. Values for fVEG, albedo, and LAI, derived from 1-km-resolution Advanced Very High Resolution Radiometer data, are inserted into PLACE, and changes in model-simulated 1.5-m air temperatures in Oklahoma during July of 1997 are documented. Use of the land cover data provides a clear improvement in afternoon temperature forecasts when compared with model runs with monthly climatological values for each land cover type. However, temperature forecasts from MM5 without PLACE are significantly more accurate than those with PLACE, even when the land cover data are incorporated into the model. When only the temperature observations above 37 degree C are analyzed, however, the simulations from the high-resolution land cover dataset with PLACE significantly outperform MM5 without PLACE. Previous land surface models have simply used (at best) climatological values of these crucial land cover parameters. The ability to improve model simulations of surface energy fluxes and the resultant temperatures in a diagnostic sense provides promise for future attempts at ingesting satellite-derived land cover data into numerical models. These model improvements would likely be most helpful in predictions of extreme temperature events (during drought or extremely wet conditions) for which current numerical weather prediction models often perform poorly. The potential value of real-time land cover information for model initialization is substantial.

According to our calculations, (1) the discrepancy between estimates of safety indices for gravity and wind loads is an artifact that can be removed by using current knowledge on probability distributions of extreme wind speeds; (2) the disregard in the ASCE 7-98 Standard of (a) knowledge uncertainties, and (b) errors inherent in the limited number of climatological data on which hurricane wind speed simulations are based, leads to incorrect wind load factor estimates; and (3) increasing beyond 30 min or even 20 min the length of pressure records used for the estimation of fluctuation peaks appears to have a relatively small effect on estimates of overall wind effects. We outline future research on wind directionality, sampling errors in the estimation of peak wind effects, and the use of probabilistic descriptions of wind effects and structural capacity to estimate probabilities of occurrence of nonlinear limit states, including structural collapse.

The present study found that the tide-surge interaction in the Meghna estuary shows, in general, the progressive wave nature of the local tide. If the peak of the maximum surge coincides with the tidal peak near the landfall, the surge propagates toward the north faster than when the surge peak coincides with the tidal trough. Cyclones that make landfall before the arrival of the tidal peak produce higher but shorter duration surges than those that make landfall after the arrival of the tidal peak. If the landfall time of the cyclone is kept fixed, the surge peaks are found to arrive earlier and to be of shorter duration with (i) an increase in the propagation speed of the cyclone and (ii) a decrease in the radius of the maximum cyclonic wind. For the peak of the maximum surge, it may take about 3-4 h to propagate from the southern estuary to the northernmost estuary. The surge, which propagates northward, reaches the northernmost estuary earlier and becomes longer in duration with smaller angles of crossing of the cyclone with the coastline. A slow moving cyclone with a larger radius of cyclonic wind, making landfall in the northernmost area, with a small angle of crossing relative to the Noakhali-Cox's Bazar coastline, and landfall just before the high tide is found to be the most severe cyclone, capable of producing the highest surges in the vast and shallow estuary.

Despite the considerable literature dedicated to the subject of protected areas, both terrestrial and marine, in the United States, we are not aware of work explicitly describing this dichotomy. We compared marine and terrestrial areas under federal jurisdiction to provide a quantitative assessment of the differences between the conservation of land and sea in the United States. Specifically, we compared national marine sanctuaries (including sanctuary preservation areas and ecological reserves) with national parks, national forests, and national wildlife refuges (including national wilderness preservation areas). Our results suggest that marine sanctuaries are fewer in number, smaller in total area, and smaller in percentage of area covered than are terrestrial protected areas.

The development of new technology to route PIT-tagged fish through multiple alternative pathways as they pass through the interrogation systems at the fish bypass/monitoring facilities at hydroelectric dams provides another valuable real-time tool to monitor and evaluate the migration, passage, and survival of PIT-tagged juvenile salmonids in the basin. The authors describe the current computer program and gate-control technology for routing fish, and provide detailed descriptions of three new types of fish-diversion gates. The comparative advantages and disadvantages of each gate are discussed. The prototype of a fourth diversion gate, with only one moving part, is also described.

AN - 18190521; 5218236 AB - Iteroparous species examined from the Northwest Atlantic demonstrated distinct relationships between feeding and reproduction. Two species showed an increase in feeding during the developing, ripe and running stages of reproduction, indicative of the ramper pattern. Four species showed an increase in feeding after spawning in the spent or resting stage of reproduction, indicative of the rester pattern. Two species exhibited no distinct pattern. Evidence from other species confirms these major patterns. This information may be useful to determine the effectiveness of different management measures, particularly in relation to feeding or spawning aggregations. There are two major feeding-reproductive patterns for fishes along a continuum of possibilities.

S. Endangered Species Act, a species is classified as endangered, threatened, or recovered based on the extent to which its survival is affected by one or more of five subjective factors. A key criticism of the act is that it makes no reference to quantitative or even qualitative parameters of what constitutes "danger of extinction. ' Without objective standards to guide decisionmakers, classification decisions fall prey to political and social influences. We recommend the development of species-specific, status-determining criteria as a means to rationalize and expedite the listing process and reclassification decisions, independent of the requirement for delisting criteria in recovery plans. Such criteria should (1) clearly define levels of vulnerability, (2) identify gaps in information on life-history parameters, and (3) address uncertainty in existing data. As a case study, we developed preliminary criteria for bowhead whales ( Balaena mysticetus). Thresholds for endangered and threatened status were based on World Conservation Union ( IUCN) Red List criteria and population viability analyses. Our analysis indicates that particular attention must be focused on population structure within the species to appropriately classify the degree to which one or more components of a species are vulnerable to extinction. A similar approach could be used in the classification of other species. According to our application of the IUCN criteria and those developed for similar species by Gerber and DeMaster (1999), the Bering Sea population of bowhead whales should be delisted, whereas the other four populations of bowheads should continue to be considered endangered.

Here we present results on the forecast skill of the sea ice concentration (C) fields from this system for the highly variable month of May 2000. Consistent with previous work on weather model verification, we used the root mean square error, the anomaly correlation and the index of agreement to assess the forecast skill of the system. In all cases, the skill of the model was high (e.g., anomaly correlations >0. 7) and, for times out to 72 hours, significantly better than persistence at the 95% confidence level. However, in spite of the overall high hemispheric forecast skill of PIPS, considerable spatial variability exists in the statistics. A threat index, patterned after methodologies developed for tornado forecasting, was also used to assess changes in ice concentration. Specifically, it was used to assess how well PIPS forecasts ice-free regions (C0. 7) et, pour des periodes pouvant atteindre 72 heures, significativement meilleur que la persistance avec un niveau de confiance de 95%. Toutefois, en depit du niveau general eleve de performance de PIPS au plan de la prevision hemispherique, les statistiques presentent une variabilite spatiale elevee. Un indice de risque, concu selon les methodologies developpees pour la prevision des tornades, a aussi ete utilise pour evaluer les changements dans la concentration de glace. Specifiquement, il a ete utilise pour evaluer jusqu'a quel point le systeme PIPS peut prevoir correctement les regions sans glace (C<0.15). Conformement aux resultats precedents, on a trouve que PIPS performe mieux que la persistance. On suppose, sans toutefois en faire la demonstration, que ces erreurs de prevision sont dues aux deficiences dans les champs meteorologiques utilises pour forcer le modele glace/ocean.

These charts were originally intended as navigation aids for vessels operating Northern Hemisphere sea ice-infested waters. However, it was recognized early on that these data represent a unique resource for Arctic researchers, adding significantly to sea ice data sets compiled by Walsh (1978) and others. Ice concentration records commonly derived from satellite passive microwave data are similar to the NIC data set in terms of resolution, extent and period of record but these microwave data may suffer from systematic biases related to the imaging process and algorithms used to infer ice concentration from raw data. Although the NIC digital sea ice data set has its own limitations, its starting point precedes that of the passive microwave record and avoids some of its inherent biases. This paper describes the spatial and thematic characteristics of the NIC historical data set, as well as the digital and analog data and analysis methods used to create the data set. This study also briefly investigates long-term change in Arctic ice cover. The NIC data set reveals that sea ice concentration patterns in the Atlantic and Pacific sectors of the Arctic vary in response to changes in the North Atlantic Oscillation. This result is consistent with the findings of other researchers, who used other data sets.Original Abstract: Des cartes hebdomadaires de la glace de mer produites par le Centre national des glaces (NIC) de 1972 a 1994 ont ete rendues publiques recemment en soutien a la recherche environnementale. Ces cartes etaient concues l'origine comme outil d'aide a la navigation pour les navires operant dans les eaux infestees de glace de mer dans l'hemisphere nord. Toutefois, on a realise tres tot que ces donnees constituaient une ressource unique pour les chercheurs en milieu Arctique, apportant une contribution significative aux ensembles de donnees sur la glace de mer compilees par Walsh (1978) et autres. Les enregistrements de concentration de glace derives couramment des donnees des capteurs satellitaires hyperfrequences passifs sont semblables a l'ensemble de donnees du NIC en termes de resolution, d'etendue et de periode d'enregistrement, mais ces ensembles de donnees hyperfrequences peuvent souffrir de biais systematiques relies au processus et aux algorithmes de formation de l'image utilises pour deduire la concentration de glace a partir des donnees brutes. Bien que l'ensemble des donnees numeriques de glace de mer du NIC ait ses propres limitations, les premiers enregistrements dans le champs precedent les enregistrements de donnees par capteurs hyperfrequences passifs et permettent d'eviter certains de ces biais inherents. Cet article decrit les caracteristiques spatiales et thematiques de l'ensemble de donnees historiques du NIC de meme que les donnees numeriques et analogiques et les methodes d'analyse utilisees pour creer l'ensemble de donnees. Cette etude analyse aussi brievement les changements a long terme dans le couvert de glace dans l'Arctique. L'ensemble de donnees du NIC revele que les patrons de concentration de glace de mer dans les secteurs Atlantique et Pacifique de l'Arctique varient en reponse aux changements dans l'Oscillation de l'Atlantique Nord. Ce resultat est coherent avec les resultats des recherches d'autres chercheurs qui ont utilise d'autres ensembles de donnees.

The scenarios were used in ecological risk assessment (ERA) workshops designed to help fisheries, wildlife, and resource managers determine whether they would support pre-approving the use of dispersants. Resource managers proposed a worst-case spill scenario for the Gulf of the Farallones. Models were used to compare five options--no response, mechanical, burning, and two levels of dispersants--showing the trajectories, fate, and concentration of oil in surface slicks and dispersed oil plumes. Participating biologists used current data on dispersant and dispersed oil toxicity to develop consensus-based toxicity guidelines. During the first several hours following dispersal, the simulated dispersed oil concentrations exceeded guidelines for early life-history stages of fishes and zooplankton; adult fish and crustaceans were at risk for two hours. The benefits and risks to fishes, seabirds, cetaceans, pinnipeds, sea otters, and shoreline resources (marshes, kelp beds, and protected areas) were compared for the five response options. Dispersants substantially reduced the amount of both floating and stranded oil relative to the other options. Furthermore, the higher dispersant level (85%) removed more oil than the lower level (35%). Risk assessments so far indicate that chemical dispersion can reduce the overall ecological effects of a nearshore oil spill. The final decision to preapprove dispersant use along the Pacific Coast will still require input from the political, social, and economic sectors.

Recovery will depend on knowledge of demographic variables, including age distributions and maximum longevity. A precise, reliable aging method is imperative. Otolith annuli counts use previously have been challenged. Annuli and assessed edge condition in sagittal otoliths were counted in 3791 red snapper from the Gulf of Mexico off Louisiana from 1989-92 and from 1995-98. Following validation, estimated ages were analyzed. For the 2546 specimens of known sex, both sexes showed rapid growth until about age 8-10 yr, after which growth slowed considerably. Growth models for total length at age were significantly different for male and females, suggesting differential growth between sexes, with females typically reaching larger size at older ages compared with males.

If recovery fails, other measures may be necessary, but genetic variability of stocks needs to be known first, so populations do not lose variability or within-population genetic characteristics due to management practices. Genetic differentiation in southern flounder from the northern Gulf of Mexico and northwestern Atlantic Ocean was studied. Differentiation was not extensive over most of the range studied. A discontinuity in allele frequencies was discovered on the Texas coast, suggesting that some genetic structuring is present. A distributional gap exists in the southern reaches of Florida, but it may not be an effective gene flow barrier. The isolation by distance model of population restructuring did not fit the case for southern flounder. Seasonal current patterns may explain at least some of the genetic structure.

AN - 36410059; 8972 AB - PURPOSE: The implementation of a fishery management plan for the dolphin and wahoo fishery of the Atlantic Ocean, Caribbean Sea, and the Gulf of Medico within the U.S. Exclusive Economic Zone is propsed. Problems and issues identified during scoping include those related to localized reductions in fish abundance due to high fishing pressure, disruption of markets, conflict and/or competition between recreational and commercial user groups in the dolphin fishery, reduced social and economic benefits from the fishery, high levels of bycatch, disruption of predator/prey relationships affecting dolphin and other pelagic species, and limited biological, habitat, economic, and social information with respect to exploitation of dolphin and wahoo stocks and fisheries. The overall goal of the plan is to adopt a precautionary and risk-averse approach to management which, in the first instance, would attempt to maintain the status quo. This would require that current catch levels not be exceeded and that recent conflicts between sectors of the fishery (commercial vs. recreational fishing interests) be resolved. The status quo would reflect trends associated with average catch and effort levels in the fishery during the five-year period extending from 1993 through 1997. Owing to the significant importance of the dolphin/wahoo fishery to the recreational fishing community in the Atlantic, the goal of the plan would be to maintain the current harvest level of dolphin and insure that no new fisheries develop. The overall goal of the plan for the Caribbean would be to provide a comprehensive management structure to address management needs of dolphin and wahoo and to take a precautionary and risk-averse approach in implementing a management structure and regulations to maintain management at optimum yield. The overall goal of the plan for the Gulf of Mexico would be similar to that for the Caribbean. Specific measures to be undertaken in the various areas would include permit systems, prohibition of sale of recreationally caught fish, total landings limitations, bycatch limits, recreational bag limits, commercial trip limits, size limits, establishment of fishing seasons, gear restrictions, alterations in essential fish habitat provisions, establishment of optimum yields and maximum sustainable yields, and research provisions. POSITIVE IMPACTS: In addition to reducing overexploitation of the dolphin and wahoo fisheries and reducing bycatch in the affected areas, the plan would provide for high-quality research data to determine the exact condition of the fisheries and to direct future management efforts. NEGATIVE IMPACTS: Certain management provisions could result in a small increase in operating costs for dealers, vessel owners, and operators in the fisheries. Data collection requirements would increase time costs somewhat. Revenues from the recreational fisheries would decline somewhat. Bag limits would reduce opportunities for recreational fishing in the affected areas. Gear restrictions would reduce revenue in the commercial fisheries.

T., Brosch, R., Parkhill, J., Garnier, T., Churcher, C., Harris, D., Gordon, S. V., Eiglmeier, K., Gas, S., Barry, C. E., III, et al. (1998) Nature 393, 537-544). The deduced amino acid (aa) sequence (443 aa) encoded by Mtb cya contains a single hydrophobic domain of six transmembrane helices (152 aa) in the amino-terminal half of the protein. Flanking this domain are an arginine-rich (17%) amino-terminal cytoplasmic tail (46 aa) and a carboxyl-terminal cytoplasmic domain (245 aa) with extensive homology to the catalytic core of eukaryotic adenylyl cyclases. Site-directed mutagenesis of Arg super(43) and Arg super(44) to alanine/glycine showed a loss of adenylyl cyclase activity, whereas mutagenesis to lysine restored the activity. Hence it is proposed that the formation of the catalytic site in Mtb adenylyl cyclase requires an interaction between Arg super(43) and Arg super(44) residues in the distal cytoplasmic tail and the carboxyl-terminal cytoplasmic domain. Mtb adenylyl cyclase activity at the physiological concentration of ATP (1 mM) was 475 nmol of cAMP/min/mg of membrane protein in the presence of Mn super(2+) but only 10 nmol of cAMP/min/mg of membrane protein in the presence of Mg super(2+). The physiological significance of the activation of Mtb adenylyl cyclase by Mn super(2+) is discussed in view of the presence of manganese transporter protein in mycobacteria and macrophages wherein mycobacteria reside.

AN - 36409859; 8971 AB - PURPOSE: The implementation of a coastal zone management plan for the Indiana shoreline of Lake Michigan and associated lands and waters is proposed. The lakeward boundary of the area consists of the jurisdictional borders within the lake that Indiana shares with Illinois and Michigan. The inland boundary includes those areas that drain into Indiana's portion of the lake to the state border with Illinois and the LaPorte County line. The inland coastal program boundary includes all shorelands subject to erosion or flooding, estuarine areas and wetlands, and other areas the use of which may directly and significantly affect Lake Michigan waters. The coastal program area encompasses 604 square miles of land and approximately 241 square miles of Lake Michigan. The area covers the northern portions of Lake, Porter, and LaPorte counties. Approval of the plan would allow program administrative grants to be awarded by the National Oceanic and Atmospheric Administration to the state and would require that federal actions within the affected areas be consistent with the program. The comprehensive program would consist of numerous rules on diverse management issues that are administered under Indiana law. The program would cover coastal hazards, water quality, water quantity, natural areas, fisheries, wildlife, native and exotic species, recreation, coastal access, cultural resources, economic development, pollution prevention and related waste management issues, air quality, and property rights. The program recognizes areas that have unique qualities that either make them vulnerable or increase the competition for their use; these areas are designated as "coastal areas of significance". Federal alternatives to program approval include delaying or denying approval under the circumstances that certain requirements of the Coastal Zone Management Act have not been met. POSITIVE IMPACTS: The plan would promote the beneficial use of coastal resources, prevent their impairment, and manage major activities that substantially affect numerous coastal resources. The program would enhance decision-making processes used for determining the appropriateness of actions in the coastal zone. Approvalo f the program would enhance governance of Indiana's coastal land and water uses according to coastal policies and standards contained in Indiana statutes, rules, and authorities.

AN - 71149254; 11544052 AB - Assays using living cells provide an effective means to generate activity measurements of toxins, especially in situations where the toxins are part of a complex mixture or in an unfamiliar form such as natural or synthetic derivatives or bioactive metabolites. An important step in the refinement of cell based assays is to simplify the cellular reactions needed or required to generate the functional response of interest. Advances in the engineering of functional responses in cells provide a means to direct the response to given toxins. In this report, we describe the homogeneous high level expression of the initial target for brevetoxin, the voltage dependent sodium channel in human embryonic kidney cells (HEK-293). HEK cells stably transfected with a 6.208 kb cDNA of human heart voltage-dependent Na(+) channel (hH1a) were examined as an alternative to mouse neuroblastoma cells (N2A). The HEK-hH1a cells showed a reduced dependence on cofactors, increased sensitivity to brevetoxin and a useful means to assure absolute selectivity to the sodium channel. We next assessed the assay in a reporter gene format. Expression of a panel of minimal response elements as well as the c-fos promoter failed to provide a response to brevetoxin, indicating that the HEK cells lack a necessary intermediate signaling component. The expression of voltage dependent sodium channels in HEK cells is anticipated to provide enhanced performance for cell-based detection of toxins for drug and natural product discovery, biomonitoring and environmental monitoring.

Consumer Income. Current Population Reports. AN - 62287562; ED458343 AB - This report uses data from the U.S. Census Bureau's March 2001 Current Population Survey to examine health insurance coverage. The number and percentage of people covered by employment-based health insurance rose significantly in 2000, driving the overall increase in health insurance coverage. Among the entire population age 18-64 years, workers were more likely to have health insurance than nonworkers. The proportion of uninsured declined in 2000. For poor people, the uninsured rate declined in 2000, though the rate for the near-poor increased. Hispanics were less likely than White non-Hispanics to have health insurance. The coverage rate for Blacks in 2000 did not differ statistically from the coverage rate for Asians and Pacific Islanders. American Indians and Alaska Natives were less likely to have health insurance than any other racial group. Males were less likely than females to have health insurance. The foreign-born population was less likely than the native population to be insured. Among all adults, the likelihood of being insured increased as the level of education rose. Young adults were less likely than any other age group to have health insurance. The uninsured rate for children dropped from 12.6 percent in 1999 to 11.6 percent in 2000. The highest uninsured rate for children was among those of Hispanic origin (24.9 percent). Some states had higher uninsured rates than others. (SM) AU - Mills, Robert J.

Consumer Income. Current Population Reports. AN - 62286415; ED458342 AB - This report illustrates how poverty rates vary by selected characteristics (age, race, and Hispanic origin, nativity, family composition, work experience, and geography), using data from the Census Bureau's March 2001 Current Population Survey. The 2000 poverty rate dropped half a percentage point from 1999, to 11.3 percent. This decrease was not concentrated in any one U.S. region. Blacks and female-householder families set record low poverty rates in 2000. The poverty rate for people under age 18 years dropped to 16.2 percent. Poverty rates fell for blacks and Hispanics between 1999-00. While blacks remained disproportionately poor, the difference in poverty rates between blacks and white non-Hispanics narrowed since the most recent poverty rate peak. Compared with the most recent poverty rate peak in 1993, more people in 2000 lived in families with at least one worker, and the poverty rate for people in these families fell since 1993. Four appendixes present data on poverty status by family relationship, race, and Hispanic origin 1959-2000; poverty status of people by age, race, and Hispanic origin, 1959-2000; poverty status of families by type of family, 1959-2000; and people and families in poverty by selected characteristics: 1993 and 2000.

Fe. The axial ratio c/a of h.c.p. Fe increases to approximately 1.7 at 5700 K, where aggregate bulk and shear moduli match those of the Earth's inner core. As a result of this increase, the single-crystal longitudinal anisotropy of h.c.p. Fe at high T is opposite to that at low T. A model is presented of the polycrystalline texture of the inner core in which basal planes of Fe are partially aligned with the rotation axis, and this, it is suggested, accounts for inner-core anisotropy. Elastic moduli are presented for h.c.p. Fe at 4000, 5000 and 6000 K.

The horizontal velocity data allow us to calculate the vertical velocity component by vertically integrating the continuity equation. Given the three-dimensional temperature flux divergence, we examine the role of the ocean circulation in SST. Upwelling and downwelling are found to be associated with cooling and warming, respectively, suggesting that a vertical velocity component of either sign affects SST. Both the temperature flux divergence and advective formulations for the ocean circulation's influence on the temperature budget show times when the ocean circulation appears to provide the primary control on SST and times when this is not the case, with the flux divergence formulation performing better than the advective formulation. Statistically, within a bandwidth encompassing the tropical instability waves and the intraseasonal variations, roughly half of the SST variation is accounted for by the ocean circulation. These results are encouraging, given that data sets with different spatial and temporal scales have been used. They suggest that future field experimentation which utilizes a flux divergence array with velocity and temperature data sampled at the same spatial and temporal scales will yield quantitatively improved results. The analyses also show that the ocean circulation, on average, provides a cooling effect requiring the net surface heat flux to be positive to maintain the mean background state. The cooling effect is mainly controlled by mean ocean circulation and temperature fields. Copyright 2001 by the American Geophysical Union.

The model was able to reproduce all of the basic features of the thermal structure in Lake Michigan: spring thermal bar, full stratification, deepening of the thermocline during the fall cooling, and finally, an overturn in the late fall. Large-scale circulation patterns tend to be cyclonic (counterclockwise), with cyclonic circulation within each subbasin. The largest currents and maximum cyclonic vorticity occur in the fall and winter when temperature gradients are low but wind stresses are strongest. The smallest currents and minimum cyclonic vorticity occur in spring and summer when temperature gradients are strong but wind stresses are weakest. All these facts are in agreement with observations. The main shortcoming of the model was that it tended to predict a more diffuse thermocline than was indicated by observations and explained only up to half of the variance observed in horizontal currents at timescales shorter than a day.

AN - 20713412; 5315151 AB - Two major ship groundings in 1989 damaged reef habitats in the northern Florida Keys National Marine Sanctuary, the MV Alec Owen Maitland and the MV Elpis. Both sites underwent structural restoration in 1995, involving the emplacement of exogenous structures to stabilize loose rubble and fill in lost reef framework. These two projects of the same age and similar location, but differing in depth and structure design, provide an opportunity to evaluate restoration success in terms of the re-establishment of coral populations via in situ recruitment. In fact, coral assemblages differ markedly in density, size distribution, and diversity between the two sites. Within the Maitland site, coral recruitment is positively associated with rough limerocks embedded in the concrete restoration structure, but the coral assemblage is dominated by a single species, Porites astreoides. At the Elpis site, the juvenile coral assemblage has substantial representation by four taxa and has estimated juvenile density 50% greater than Maitland. These differences are associated with differences in the benthic algal assemblages at the two sites. It is hypothesized that differences in algal assemblage may result from differing structure designs (e.g., differing material, surface texture, and/or surface orientation) and may mediate differential coral recruitment success at the two sites.

When environmental conditions were conducive to coral bleaching, according to different models, 'alerts' were automatically posted to the World-Wide Web and emailed to researchers so they could verify and study bleaching events as they might happen. The models were refined using feedback from field data on bleaching recorded after alerts from the expert system. The expert system was programmed to produce alerts when sea temperatures over 30 degree C occurred, or when temperatures of 30 degree C occurred concomitant with low winds. Alerts were produced in June 1998 when these conditions were met, but bleaching did not occur. Reconfiguration of the system, which included a point system for three models (high sea temperature only, high sea temperature plus low winds, high sea temperature plus low winds plus low tide), resulted in the transmittal of alerts which coincided with bleaching during early August, 1998. Bleaching occurred after sea temperature reached an average of 31.5 degree C over a period of 3 d, with excursions over 31.8 degree C occurring over 15 times during those 3 d. High sea temperatures, low wind speeds and a very low tide occurred coincident to the time of bleaching, but it was not possible to tell if these were factors acting synergistically.

We report here the three-dimensional NMR structure in solution of a homologue from Haemophilus influenzae, HI0257, that has 64% sequence identity to protein Y. The 107 residue protein has a beta - alpha - beta - beta - beta - alpha folding topology with two parallel alpha -helices packed against the same side of a four-stranded beta -sheet. The closest structural relatives are proteins with the double-stranded RNA-binding domain (dsRBD) motif although there is little (< 10%) sequence homology. The most immediate differences between the dsRBD and HI0257 structures are that (1) HI0257 has a larger beta -sheet motif with an extra beta -strand at the N-terminus, (2) the helices are parallel in HI0257 but at an angle of about 30 degree to each other in the dsRBD, and (3) HI0257 lacks the extended loop commonly seen between the first and second beta -strands of the dsRBD. Further, an analysis of the surface electrostatic potential in HI0257 and the dsRBD family reveals significant differences in the location of contiguous positively (and negatively) charged regions. The structural data, in combination with sequence analysis of HI0257 and its homologues, suggest that the most likely mode of RNA recognition for HI0257 may be distinct from that of the dsRBD family of proteins.

Most of the convection was organized in two mesoscale convective systems (MCSs) and a line of storms attached to the Pyrenees Mountains. One of these storms produced rainfalls in excess of 200 mm in 3 h and severe flash floods in the Biescas area. The end of the convection in the Biescas area occurred after merger of the storm with one of the MCSs that approached from the southwest. A high-resolution (4-km grid length) simulation of the event reproduces the observed timing and interactions of the convective systems, as well as the general rainfall pattern. The highly localized rainfall core at Biescas is well located, although the peak rainfall amount is underestimated. The success of the model at triggering the convection at the proper locations and time results from a reasonably accurate prediction of mesoscale features of the low-level flow pattern, such as a thermal mesolow in the Ebro valley, deformation zone, upslope wind systems, and the pushing of a cold front in the upper portion of the valley. After the onset of the initial convection, the role of the convectively induced cold pools and outflows for the propagation of the convective systems is shown to be very important. In particular, the MCS interacting with the Biescas convection was driven by strong mesoscale ascent established between the convectively induced outflows, the upvalley southeasterly winds sustained by the mesolow, and the downvalley northwesterly winds associated with the cold front. After the interaction, the convection in Biescas ceased because of the interruption of the southerly upslope flow caused by the convective cold pools. Finally, the explosive character of convection after noon and its initial focusing in uplands and slopes suggest that diurnal forcing could have played a decisive role. This idea is validated by means of simulations.

The authors previously developed an algorithm to retrieve temperature and dewpoint profiles from a combination of infrared [high-resolution infrared radiation sounder (HIRS), 18-20-km resolution] and microwave [Advanced Microwave Sounding Unit-A (AMSU-A), 48-km resolution] data, using collocated radiosondes. Besides (and separately from) the estimation problem, one key question in the context of model initialization is how to blend multiresolution data to generate fields at the spatial resolution of the NWP model of interest. In this paper, a fractal downscaling technique is proposed to blend multiresolution satellite data and generate brightness temperature fields at 1-km resolution. The downscaled HIRS and AMSU-A data subsequently can be processed by the retrieval algorithm to derive temperature and dewpoint fields at the same resolution. The utility of these products as an initial condition for NWP models was assessed in the context of regional quantitative precipitation forecasting (QPF) applications using a limited-area orographic precipitation model nested with a mesoscale model. Results from the simulation of a wintertime storm in the Pocono Mountains of the mid-Atlantic region show improvement in QPF skill when the satellite-derived initial conditions were used. However, the disparity between the sparse times when the satellite data are available (12-h intervals) vis-a-vis the hourly import of boundary conditions from the host model lessens the impact of improved initial conditions. This result suggests that gains in QPF skill are linked to the availability of relevant remote sensing data at time intervals consistent with the useful memory of initial conditions in NWP models.

ER - TY - JOUR T1 - Four years of continuous surface aerosol measurements from the Department of Energy's Atmospheric Radiation Measurement Program Southern Great Plains Cloud and Radiation Testbed site AN - 18214569; 5276001 AB - Continuous measurements of the optical and microphysical properties of aerosol particles have been made at the Department of Energy's Atmospheric Radiation Measurement Program Southern Great Plains Cloud and Radiation Testbed (CART) site covering the 4-year period from July 1996 through June 2000. Hourly, daily, and monthly statistics have been calculated that illustrate aerosol variability over a range of timescales. A pronounced peak in total particle number, centered on the midafternoon hours (local time), is evident in the hourly statistics. A broad early morning peak in the concentration of particles >0.1- mu m aerodynamic diameter corresponds with a similar peak in aerosol light-scattering coefficient, sigma sub(sp). No strong cycles were observed in the daily statistics, suggesting that day of the week has only a minor influence on the observed aerosol variability. The sigma sub(sp) at a wavelength of 550 nm for the 4-year period showed a median value of 33 Mm super(-1) and was highest in February and August. The median fraction of aerosol light scattering at 550 nm due to particles <1- mu m aerodynamic diameter was 0.85 over the entire record. The median aerosol light absorption coefficient, sigma sub(ap), for the 4-year period was similar to 1.5 Mm super(-1) and was observed to be highest in late summer and autumn. The sigma sub(ap) showed an increasing trend of nearly 0.5 Mm super(-1) yr, possibly due to increased agricultural field burning in the area. The occurrence of an autumn decrease in single-scattering albedo, omega sub(0), was observed and may be caused by regional-scale agricultural or transportation activities or seasonal changes in atmospheric flow patterns. The median value for omega sub(0) over the 4-year period was 0.95, but this value has decreased similar to 1-2% yr super(-1) presumably due to increased agricultural burning. Numerous field fires during the second half of 1999 influenced the surface aerosol at the CART site causing substantial variability of aerosol optical properties. The aerosol hygroscopic growth factor (f(RH)), corresponding to a relative humidity increase of 40-85%, showed a median value of 1.83 for 1999, although much lower values were observed during periods that were probably influenced by locally generated smoke and dust aerosols (median f(RH) = 1.55 and 1.59, respectively).

The cumulative pressures on coral reef ecosystems, such as climate change, pollution, overfishing, coastal development, and other human activities threaten their existence. The Global Coral Reef Monitoring Network (GCRMN 2000) reported that by 1998, 11 percent of the world's coral reefs had already been destroyed. If man-made and natural destructive activities affecting coral reefs continue, it is estimated that up to 60 percent of the ocean's reefs could be gone within the next 30 years (GCRMN 2000).

Narwhals spent less time at the surface than belugas did, and the surfacing time of belugas also varied between localities. No clear differences in surfacing time were associated with the time of day, but belugas tended to make more dives during the night than during the day. Despite large variability in surfacing behaviour among individual whales, time spent at the surface by both species declined from August through November. The few data collected from narwhals from November to February indicate that surfacing times remained low during this period although more than 25% of each 6 h period was spent at the surface. Whales made between 2 and 20 dives per hour, and narwhals made significantly fewer dives than did belugas, for which number of dives varied with locality. The number of dives deeper than 8 m declined substantially during the autumn for belugas and narwhals that were moving offshore. When travelling, the whales apparently made fewer dives than at other times.

A capital sigma PAH model was applied to freshwater sediments. This study is the first attempt to use a capital sigma PAH model based on water-only, median lethal concentration (LC50) toxic unit (TU) values for sediment-associated PAH mixtures and its application to freshwater sediments. To predict the toxicity (i.e., mortality) from contaminated sediments to H. azteca, an interstitial water TU, calculated as the ambient interstitial water concentration divided by the water-only LC50 in which the interstitial water concentrations were predicted by equilibrium partitioning theory, was used. Assuming additive toxicity for PAH, the sum of TUs was calculated to predict the total toxicity of PAH mixtures in sediments. The capital sigma PAH model was developed from 10- and 14-d H. azteca water-only LC50 values. To obtain estimates of LC50 values for a wide range of PAHs, a quantitative structure-activity relationship (QSAR) model (log LC50 - log K sub(ow)) with a constant slope was derived using the time-variable LC50 values for four PAH congeners. The logistic-regression model was derived to assess the concentration-response relationship for field sediments, which showed that 1.3 (0.6-3.9) TU were required for a 50% probability that a sediment was toxic. The logistic-regression model reflects both the effects of co-occurring contaminants (i.e., nonmeasured PAH and unknown pollutants) and the overestimation of exposure to sediment-associated PAH. An apparent site-specific bioavailability limitation of sediment-associated PAH was found for a site contaminated by creosote. At this site, no toxic samples were less than 3.9 TU. Finally, the predictability of the capital sigma PAH model can be affected by species-specific responses (Hyalella vs Rhepoxynius); chemical specific (PAH vs DDT in H. azteca) biases, which are not incorporated in the equilibrium partitioning model; and the uncertainty from site-specific effects (creosote vs other sources of PAH contamination) on the bioavailability of sediment-associated PAH mixtures.

This method uses existing bottom sediments to form terraces or ridges at marsh elevation. A terrace field is constructed by arranging these ridges in some pattern that maximizes intertidal edge and minimizes fetch between ridges; the intertidal area is planted with marsh vegetation. We examined the habitat value of terracing for fishery species at Sabine National Wildlife Refuge, Louisiana (USA) in spring and fall 1999 by quantifying and comparing nekton densities in a 9-yr-old terrace field and nearby reference area using a 1-m super(2) drop sampler. Decapod crustaceans were more abundant than fishes, composing 62% and 95% of all organisms we collected in spring and fall, respectively. White shrimp Litopenaeus setiferus, dagger-blade grass shrimp Palaemonetes pugio, blue crab Callinectes sapidus, and brown shrimp Farfantepenaeus aztecus accounted for 94% of all crustaceans, whereas 60% of all fishes were gulf menhaden Brevoortia patronus. Mean densities of white shrimp (fall), daggerblade grass shrimp, blue crab, and brown shrimp (spring) were significantly greater in terrace marsh than on non-vegetated bottom in the reference pond. Densities of most nekton on non-vegetated bottom were similar in the terrace field and the reference pond, but gulf menhaden and white shrimp had higher densities at terrace pond sites and brown shrimp (spring) were more abundant at reference pond sites. The pattern for biomass was similar to that for density in that the mean biomass of most species was significantly greater at terrace marsh sites than reference pond sites and similar at terrace and reference pond sites. Terrace marsh, however, was not functionally equivalent to natural marsh, as mean densities of daggerblade grass shrimp (fall), brown shrimp (spring), and blue crab and mean biomass of white shrimp (fall), striped mullet Mugil cephalus (spring), and spotted seatrout Cynoscion nebulosus (fall) were greater at reference marsh sites than terrace marsh sites. Using these density and biomass patterns and the percentage of marsh and pond area in the terrace field, we concluded that terrace fields support higher standing crops of most fishery species compared with shallow marsh ponds of similar size. Future restoration projects could include design changes to increase the proportion of marsh in a terrace field and enhance the habitat value of marsh terraces for fishery species.

Surface roughness in turn was correlated with geomorphology or soil properties for Kuwait, Iraq, part of Syria, Saudi Arabia, the United Arab Emirates and Oman. The PM sub(10) emission algorithm was incorporated into a Lagrangian transport and dispersion model. PM sub(10) air concentrations were computed from August 1990 through August 1991. The model predicted about the right number of dust events over Kuwait (events occur 18% of the time). The model results agreed quantitatively with measurements at four locations in Saudi Arabia and one in Kuwait for one major dust event (> 1000 mu g/m super(3)). However, for smaller scale dust events (200-1000 mu g/m super(3)), especially at the coastal sampling locations, the model substantially over-predicted the air concentrations. Part of the over-prediction was attributed to the entrainment of dust-free air by the sea breeze, a flow feature not represented by the large-scale gridded meteorological data fields used in the model computation. Another part of the over-prediction was the model's strong sensitivity to threshold friction velocity and the surface soil texture coefficient (the soil emission factor), and the difficulty in accurately representing these parameters in the model. A comparison of the model predicted PM sub(10) spatial pattern with the TOMS satellite aerosol index (AI) yielded a spatial pattern covering a major portion of Saudi Arabia that was quite similar to the observed AI pattern.

In yeast the protein is expressed before initiation of DNA replication and is thought to be essential for loading of the helicase onto origin DNA. The biochemical properties of the protein, however, are largely unknown. Using three archaeal homologues of Cdc6, it was found that the proteins are autophosphorylated on Ser residues. The winged-helix domain at the C terminus of Cdc6 interacts with DNA, which apparently regulates the autophosphorylation reaction. Yeast Cdc18 was also found to autophosphorylate, suggesting that this function of Cdc6 may play a widely conserved and essential role in replication initiation.

The importance of sea surface temperature (SST) anomalies in forcing atmospheric teleconnections is specifically addressed through analyses of atmospheric general circulation model (GCM) simulations forced with the monthly varying SSTs of the years 1950-98. The results from three different models, each run in ensemble mode, are compared with observations of extreme April-June precipitation events in the central United States during the last half of the twentieth century. Analysis of GCM simulations of April-June 1988 indicates that the atmospheric circulation anomalies associated with the 1988 drought were not forced by SST anomalies and that the coexistence of central U.S. drought and La Nina during that spring was coincidental. Likewise, composite analysis reveals no SST forcing for the teleconnections associated with extreme dry spring seasons over the central United States during the last half of the twentieth century in either observations or GCMs. Nonetheless, this characteristic teleconnection pattern of the composite analysis resembles the circulation anomalies of 1988. The results imply that such drought events and the teleconnections related with them have little SST-based predictability. A somewhat different conclusion is drawn regarding the role of tropical SSTs in the occurrence of extreme wet spring seasons over the central United States. Simulations of the 1993 flood period exhibit skill in reproducing the seasonal circulation anomalies over the Pacific-North American region, and the ensemble mean precipitation anomalies in one GCM nearly replicate the observed strength and distribution of positive rainfall anomalies over the United States. Further composite analysis of extreme wet spring seasons over the last half of the twentieth century confirms the impression gathered from the 1993 case study, with observations and all three GCMs possessing positive tropical east Pacific SST anomalies in conjunction with extreme wet spring seasons over the central United States. Some SST-based potential predictability of extreme wet springs over the central United States consequently exists.

Contrary to predictions based on data from other Pacific ridges, hydrothermal plumes over the inflated 16 degree N segment were less extensive and weaker than along the narrower, rifted 17 degree N segment. Remarkably, the 17 degree N segment has a plume incidence equal to the mean of superfast spreading segments from the southern EPR. The data suggest that the local permeability environment in this region controls the expression of hydrothermal activity in the water column. The 16 degree N segment, which has little or no indication of faulting, may have its hydrothermal activity presently suppressed by widespread volcanic flows that act as an impermeable cap over much of the segment. Activity on the 17 degree N segment may be tectonically enhanced, with hydrothermal fluids circulating through deep faults to a cracking front. Within each segment, intense hydrothermal plumes characteristic of focused discharge seem associated with clearly rifted areas, while weaker water column signals characteristic of diffuse discharge are associated with unrifted portions of the ridge axis that appear dominated by magmatism. Previous studies at intermediate- to-superfast spreading ridges have emphasized a positive correlation between local magmatic budget and hydrothermal activity. Our data suggest, however, that even at fast rates local tectonics can control the extent and nature of hydrothermal activity, as documented for several sites on the slow-spreading Mid-Atlantic Ridge. Despite the segment-scale incongruity between hydrothermal activity and magmatic budget, the fraction of total ridge length between 15 degree 20' and 18 degree 30'N overlain by plumes (0.39) follows the existing global correlation between plume incidence and spreading rate.

Climate change and associate weather patterns are an important factor in coral reef bleaching, which causes the death and transformation of the coral reef ecosystem. National responses to this decline include the Coral Reef Protection Executive order 13089, drawing on resources in several federal agencies to map and monitor coral reef activities. Mapping is achieved with a combination of aerial surveillance and satellite imagery. The monitoring program is implemented in concert with fish and habitat monitoring studies, and the integration of ecology and habitat maps.

AN - 36409592; 8945 AB - PURPOSE: The implementation of a plan for the protection of Steller sea lions under the authority of the fishery management plans for groundfish fisheries of the Gulf of Alaska and the Bering Sea and Aleutian Islands is proposed. Within fisheries in the range of the Steller sea lion west of Cape Suckling, the species is considered endangered; within the area east of Cape Suckling, the species is considered endangered. In the core region from Kenai Peninsula to Kiska Island, counts of adult and juvenile sea lions have declined by approximately 80 percent since the population size was estimated in the late 1950s. Five alternatives, including a No Action Alternative (Alternative 1), are considered in this draft supplemental programmatic EIS. The primary purpose of the proposed action is to modify the management plan for the Pollock, Pacific cod, and Atka mackerel fisheries such that the reconfigured fisheries do not jeopardize the continued existence of Steller sea lions or adversely affect their crucial habitat. If more than one alternative action would accomplish the primary purpose, a secondary objective would be to modify the fisheries such that the reconfiguration minimizes the economic and social costs that would be imposed on the commercial fishing industry and the associated coastal communities. The preferred alternative (Alternative 4) would involve an area and fishery specific approach. The approach would allow for different types of management measures in the three affected areas. Essential measures would include fishery-specific closed areas around rookeries and hallouts, together with seasonal and catch apportionments. Three options for closure areas would be considered; these include small boat exemptions for the Chignik and /or Unalaska tribes and gear-specific zones for the Gulf of Alaska Pacific cod fisheries. POSITIVE IMPACTS: The preferred alternative would protect the habitat and individuals of the Steller sea lion species from further incidental take by fishing interests in the affected fisheries. The socioeconomic impacts of the preferred alternative would be as limited as possible. NEGATIVE IMPACTS: Conditionally significant effects would occur with respect to the harvest of prey species for Steller sea lion. Economic returns from the affected fisheries would decline by between one and six percent overall; specific regions could suffer from losses of up to 17 percent.

AN - 36397049; 8938 AB - PURPOSE: The improvement of 30-miles of Interstate 405 (I-405),adjacent arterials, and transit facilities throughout the I-405 corridor between its southern intersection with I-5 in the city of Tukwila in King County and its northern intersection with I-5 in Snohomish County, Washington is proposed. I-405 is the region's dominant north-south travel corridor east of I-5, and it serves as the designated military route due to the constricted nature of I-5. Currently, I-405 varies from six to 10 lanes within the corridor under consideration. Five alternatives, including a No Action Alternative, are considered in this draft programmatic EIS. Action alternatives include construction of a range of highway, arterial, fixed-guideway high-capacity transit, bus rapid transit, local bus transit, transportation demand management (TDM), and non-motorized transportation improvements. Action Alternative 1 would provide a physically separated, fixed-guideway high-capacity transit(HCT) system serving major activity centers. Basic improvements would be made to I-405, though no general purpose lanes would be added. TDM strategies would include evaluation of regional transportation pricing. Alternative 2 would also provide am HCT system as well as substantially expanding local bus transit service and incorporating high-occupancy-vehicle (HOV)freeway-to-freeway ramps, arterial HOV for transit services, additional park-and-ride and transit center capacity, and improvements for pedestrian and bicycle movements. Alternative 3 would expand I-405 by up to two lanes in each direction, along with major interchange and connecting arterial /freeway capacity improvements, HOV direct access ramps, arterial continuity improvements, bus rapid transit through the corridor, expanded local bus transit service, additional park-and-ride and transit center capacity, and freight traffic improvements. Alternative 4 would provide one additional lane in each direction on I-405 along with a four-lane I-405 express roadway and improved major interchanges. Arterial continuity improvements, HOV direct access ramps, expanded local bus transit service, and improvements for pedestrian and bicycle movements. Cost estimates for the action alternatives range from $5.3 billion to $11.3 billion. POSITIVE IMPACTS: The project would reduce traffic congestion in the corridor and improve personal and freight mobility over the next 20 to 30 years. Encouragement of the use of HOV lanes and transit services and/or increased lane capacity would increase transportation efficiency, reducing energy consumption per vehicle-mile as well as emissions of air pollutants and runoff to receiving fish-bearing surface waters. NEGATIVE IMPACTS: Rights-of-way requirements would result in the displacement of residential and commercial units as well as farmland, wetlands and other riparian habitat, floodplain land, shoreline land, parkland, and bald eagle habitat. Major utility relocations would be required. Historic and archaeological resources would also be affected. Up to approximately 2,500 residential receptors would be exposed to traffic-generated noise levels in excess of federal standards.

AN - 36418282; 8934 AB - PURPOSE: Dredging and disposal of dredged material in relation to maintenance of the Providence River and Harbor Federal Navigation Project, Rhode Island are proposed. The federal project, a 16.8-mile channel, begins near the head of Providence Harbor and follows the river on a southerly course to deep water near Prudence Island. The upper 2.5 miles comprise the main harbor. Providence River and Harbor together constitute the principal commercial waterway in Rhode Island. Deep-draft traffic in Providence River and Harbor consists mainly of tankers, barges, and general cargo vessels. There has been no significant dredging in Rhode Island since 1976. Since that time, shoaling has reduced controlling depths in the channel to as shallow as 30 feet below mean low water. The present level of shoaling has forced the Coast Guard to place one-way traffic and draft restrictions on ship traffic in the channel. A total of 158 potential disposal sites were screened, along with the impacts of 17 projects submitted by applicants for federal permits. Sixteen disposal options at 18 locations for dredged material disposal are evaluated and compared in this final EIS. Disposal alternatives include upland, open water, confined aquatic disposal, and disposal for the purposes of habitat restoration. The preferred alternative would involve dredging the federal channel and harbor to the authorized depth of 40 feet below mean low water at the authorized width of 600 feet, disposal of approximately 1.2 million cubic yards of contaminated dredged sediment in a confined aquatic disposal cell near the channel, disposal of approximately 5.0 million cubic yards of clean material in the Rhode Island Sound approximately 10 miles southeast of Point Judith, dewatering and storage of sand and gravel excavated from the confined aquatic disposal cells at up land sites for later use by public and private organizations, placing clean silt and sand and gravel from the cells on top of the maintenance silt to maintain existing sediment characteristics at the open water disposal site, and use of a small portion of sand and gravel to restore colony nesting waterbird habitat at Spar Island in Mount Hope Bay. Cost of the preferred alternative is estimated at $90.68 million. POSITIVE IMPACTS: The navigational efficiency of the harbor would be restored and maintained, supporting the local and regional economy. Deep draft navigation would provide for cost reductions for shippers transporting goods, reductions directly related to the costs consumers pay for products such as gasoline, home heating oil, and other products. Disturbance of bottom sediment by ships passing over shoals would cease, and the possibility of groundings and oil spills would decline significantly. NEGATIVE IMPACTS: Dredging and disposal operations would result in temporary increases in suspended solids and contaminants in the water column, burial of aquatic resources, and the resultant economic impacts on the fishing interests dependent on the bay.

AN - 71197649; 11569861 AB - The National Institute of Standards and Technology (NIST) has had a major quality-assurance role in the federal effort to reduce lead poisoning of children in the United States through its mission of ensuring the accuracy of chemical measurements. NIST certifies reference materials (standard reference materials--SRMs) that are used to benchmark measurements by secondary and field methods of analysis--to ensure that decisions of great health and economic impact are soundly based on good measurement science. Over the past 10 years, in cooperation with the US Environmental Protection Agency (EPA), US Department of Housing and Urban Development (HUD), and the United States Geological Survey (USGS), NIST has prepared and certified SRMs for lead content in soil, indoor dust, and paint. The role of these materials in meeting regulatory and abatement needs is described and their certified values are summarized.

AN - 71192508; 11569860 AB - Standard reference material (SRM) 2584 (Trace Elements in Indoor Dust) was developed as a reference standard for evaluating field methods and for validating laboratory and reference methods for the assessment of lead contamination and exposure. In addition to lead, the toxic trace elements As, Cd, Cr, and Hg, at approximately 17, 10, 140, and 5 microg g(-1), respectively, have been certified in the SRM. These four analytes were successfully determined by use of high-resolution inductively coupled plasma mass spectrometry (HR-ICP-MS). Isobaric interferences at masses of As and Cr were resolved by using the high resolution mode (nominal 8000) and the medium resolution mode (nominal 3000), respectively, of the instrument. The effects of a significant drift in analyte sensitivity in the course of measurement were rectified by use of internal standardization, single spike standard addition, and an optimized analysis sequence. The results were compared with those obtained by instrumental neutron activation analysis (INAA) and isotope dilution inductively coupled plasma mass spectrometry (ID-ICP-MS). The results for the quality control, SRM 2704 (Buffalo River Sediment), were in good agreement with the certified values, indicated by the uncertainty intervals of the measured values overlapping the certified intervals at 95% confidence level.

The task of the HUP is to quantify the hydrologic uncertainty under the hypothesis that there is no precipitation uncertainty. The hydrologic uncertainty is the aggregate of all uncertainties arising from sources other than those quantified by the PQPF. The precipitation-dependent HUP has two branches, each conditional on the hypothesized occurrence or nonoccurrence of precipitation during the period covered by the PQPF (here 24h). Under each hypothesis, the time series of river stages (here at 24-h steps) is modeled a priori as a Markov process of order one with nonstationary transition distributions. The families of prior distributions and likelihood functions are all nonstationary (with forecast lead time) and meta-Gaussian (with respect to their multivariate dependence structure). For each lead time, Bayesian revision yields two families of posterior distributions whose mixture, determined by the probability of precipitation occurrence, characterizes the hydrologic uncertainty. Estimation and validation of the HUP are described using data from the operational forecast system (OFS) of the National Weather Service (NWS) for a 1430 km (super 3) headwater basin.

The method uses the precise measurement of several metals whose proportions contrast strongly between dust and salt and vary substantially between dust types. The method is applied to a small suite of ice samples from the Taylor Dome core in coastal West Antarctica. In glacial times wind strength in the West Antarctic region was apparently high, and extensive sea-ice cover prevented incorporation of salt into the atmospheric load. At the termination of the glacial period, increased salt in the dust-salt mixture indicates that sea ice diminished, but wind strength continued high, and unchanged dust composition indicates unchanged source areas. At about 10,000-11,000 y.B.P., sea-ice cover have briefly returned to glacial conditions, but wind conditions remained in the milder postglacial condition. Next, sea ice retreated, and an abrupt change in dust composition indicates changed source materials or terranes. Extension of this analysis to more sites, should provide firm constraints on past wind strengths, extent of sea-ice cover, deposition fluxes of salt and dust, and changing continental source areas of dust.

These aerosols are complex mixtures of soil dust and anthropogenic particles from a variety of sources, including fossil fuel combustion, biomass burning, mining, smelting, and other industrial processes, plus reaction products of heterogeneous processes that affect these particles during transport. In the coastal marine atmosphere, these particles could be further mixed with marine aerosols. To provide examples of the diversity of chemical and physical properties of east Asian aerosols in the spring, individual aerosol particle samples were collected in April and May 1999 in three different environments in China: Qingdao on the coast of the East China Sea, Beijing in the northeast interior, and Mount Waliguan in remote northwestern China. Results reveal that aerosols in this region are complex and heterogeneous. In addition to significant differences in aerosol composition and size distributions among the samples, each sample contains a large number of polyphase aggregates. Many of the particles also have irregular shapes; for a number of the particle types, the irregular shapes should persist even at high ambient RH. Because composition, degree and nature of polyphase aggregation, and shape all effect aerosol radiative properties, the complex state of east Asian aerosols presents a challenge for the modeling of aerosol radiative forcing in the region.

One uncertainty in comparing marine geologic records of millennial-scale variability is the extent to which mixing of sediment by organisms at the seafloor (bioturbation) may attenuate millennial-scale events in the stratigraphic record. Evidence of attenuation of millennial variability can be found in cores with sedimentation rates in the range of 5-15 cm/kyr. Modeling the attenuation of a hypothetical input time series similar to GISP2 using a moderate level of mixing provides estimates of attenuation as a function of sedimentation rate. The amplitude of a 4 kyr duration event is reduced by 50% for sedimentation rates approximately 10 cm/kyr and reduced by 20% for sedimentation rates of 20 cm/kyr. Minimal attenuation (<5%) is achieved only when the sedimentation rate exceeds 50 cm/kyr for a 4 kyr duration event and 70 cm/kyr for a 2 kyr duration event. The intensity of mixing plays a role in determining how much attenuation occurs. The amplitude of a 4 kyr duration event in a 10 cm/kyr core is reduced by 75% under strong mixing or reduced by 25% under weak mixing. This study indicates that the original amplitude of Dansgaard-Oeschger (DO) millennial-scale events observed during the last glacial may be twice the observed amplitude for cores with sedimentation rates 10-20 cm/kyr that have experienced moderate bioturbation. Regional comparisons of the amplitude of millennial-scale variability will require cores with weak mixing or sedimentation rates exceeding 50 cm/kyr in order to avoid biased estimates of the amplitude of millennial-scale (4 kyr duration) variability.

Using the National Oceanic and Atmospheric Administration (NOAA) advanced very high resolution radiometer (AVHRR) channel 1, we also measured the aerosol optical depth (AOD (sub S ) ) and albedo over a region of the North Atlantic Ocean extending from 15 degrees -35 degrees N to 12 degrees -25 degrees W. We observe large changes in AT (sub T ) and AOD (sub T ) when dust outbreaks pass over this region. Using all these data, we derive the asymmetry factor (g), the single-scattering albedo (omega ), and the local mean AOD (sub T ) and we compute the direct radiative forcing Delta F attributable to mineral dust. The local radiative forcing obtained is over the ocean Delta F = -9.7 W/m2 and for the land Delta F = -4.5 W/m (super 2) with an error of + or -25%. Extending these results to global-scale averages, we obtain values of Delta F of-1.22 W/m (super 2) over the ocean and -0.57 W/m (super 2) over land.

AN - 50152840; 2002-036317 AB - The Gravity Recovery and Climate Experiment (GRACE) satellite mission will resolve temporal variations in gravity orders of magnitude more accurately and with considerably higher resolution than any existing satellite. Effects of atmospheric mass over land will be removed prior to estimating the gravitational field, using surface pressure fields generated by global weather forecast centers. To recover the continental hydrological signal with an accuracy of 1 cm of equivalent water thickness down to scales of a few hundred kilometers, atmospheric pressure must be known to an accuracy of 1 mbar or better. We estimate errors in analyzed pressure fields and the impact of those errors on GRACE surface mass estimates by comparing analyzed fields with barometric surface pressure measurements in the United States and North Africa/Arabian peninsula. We consider (1) the error in 30-day averages of the pressure field, significant because the final GRACE product will average measurements collected over 30-day intervals, and (2) the short-period error in the pressure fields which would be aliased by GRACE orbital passes. Because the GRACE results will average surface mass over scales of several hundred kilometers, we assess the pressure field accuracy averaged over those same spatial scales. The atmospheric error over the 30-day averaging period, which will map directly into GRACE data, is generally < 0.5 mbar. Consequently, analyzed pressure fields will be adequate to remove the atmospheric contribution from GRACE hydrological estimates to sub centimeter levels. However, the short-period error in the pressure field, which would alias into GRACE data, could potentially contribute errors equivalent to 1 cm of water thickness. We also show that given sufficiently dense barometric coverage, an adequate surface pressure field can be constructed from surface pressure measurements alone.

This event was observed by several in situ and remote sensing atmospheric measurement stations. Dramatic reductions in boundary layer visibility were recorded and the resultant peak backscatter coefficients exceeded prevailing upper tropospheric background conditions by at least 2 orders of magnitude. An analysis of this event is given using lidar vertical backscatter profilometry, concurrent Sun photometer opacity data, and transport modeling. At San Nicolas Island the measured and modeled aerosol optical thickness at 500 nm increased dramatically from 0.15 on April 25 to 0.52 on April 26-27. Volume size distribution on April 27 exhibited a prominent coarse mode at 1-2 mu m radius, and single-scattering albedo was observed to increase from 0.90 in the blue to 0.93 in the near infrared. Concurrent lidar observations tracked the evolution of the plume vertical structure, which consisted of up to three well-defined layers distributed throughout the free troposphere.

Four experiments with the NASA GISS atmospheric general circulation model, which includes a soil dust aerosol model, are compared, all using a prescribed climatological sea surface temperature as a lower boundary condition. In one experiment, dust is included as a dynamic tracer with no radiative effect, whereas dust interacts with radiation in the other simulations. The single-scattering albedo of dust particles is prescribed to be globally uniform in the experiments with radiatively active dust, although this albedo is varied from experiment to experiment. On a global scale the radiative forcing by dust generally causes a reduction in the atmospheric dust load, corresponding to a decreased dust source flux. The dust source flux and its changes are analyzed in more detail for the main source regions. This analysis shows that the reduction varies both with the season and with the single-scattering albedo of the dust particles. The experiments show that dust radiative forcing can lead to significant changes both in the soil dust cycle and in the climate state. To estimate dust concentration and radiative forcing by dust more accurately, dust size distributions and dust single-scattering albedo in the model should be a function of the source region, because dust concentration and the climate response to dust radiative forcing are sensitive to dust radiative parameters.

A kinetic approach under thermodynamic constraint is utilized to model the condensation/evaporation processes, and other important aerosol processes and influential components (e.g., dust/sea-salt generation, NH (sub 3) emissions, gravitational settling, nucleation) are taken into account in this analysis. The model is used to study the Pacific Exploratory Mission-West B period (March 1-6, 1994). It is found that (1) during strong continental outflow, in general, the fine aerosol mode ( 2 mu m in aerodynamic diameter) attracts nitrate. However, in the dust plume, sulfate preferentially resides in the coarse mode due to larger coarse mode mass loading; (2) particulate nitrate coupled with particulate ammonium in the fine mode is predicted over regions where high gaseous NH (sub 3) mixing ratios are present (lower courses of the Huang river); (3) dust and sea-salt particles provide important reaction surfaces for sulfate production in the troposphere and increase sulfate production rates by 20 - 80%; and (4) soil dust and sea salt provide an important source of boundary layer and free troposhpere alkaline material, and these cations play an important role in controlling the partitioning of semivolatile HNO (sub 3) throughout large portions of the troposphere, increasing particulate nitrate levels 10 - 50%.

Further, the human contribution to the mineral aerosol concentration is difficult to quantify. We have performed several global sensitivity experiments to investigate the radiative forcing due to mineral dust. Two global data sets of mineral aerosol distribution are used. Radiative transfer schemes for thermal infrared and solar radiation are used in the calculations. We have investigated the sensitivity of the global radiative forcing to the spatial distribution of the aerosols, including the altitude, the size distribution, and optical parameters. Our strongest emphasis has been on the size distribution of the mineral aerosol, for which we have found a strong sensitivity. A range of -0.7 Wm (super -2) to 0.5 Wm (super -2) is estimated for the human influence on the global radiative forcing due to mineral aerosols. We find it almost as probable with a positive radiative forcing as with a negative forcing. Even if the global mean radiative forcing is small, there are large contributions of different sign in certain regions. Copyright 2001 by the American Geophysical Union.

The site was a vegetation-free saline playa where the surface formed "ephemeral crusts," crusts that form after rainfall. Sometimes these crusts were destroyed and often a layer of particles on the crust would engage in vigorous aeolian activity. Three "phases" of active sand drifting are defined as almost no movement (extreme supply limitation), loose particles on crust with some degree of sand drift (moderate supply limitation), and unlimited source movement corresponding to a destroyed surface crust (unlimited supply). These "phases" occurred 45, 49, and 6% of the time, respectively. The accumulation of loose particles on the crust was mostly the result of in situ formation. Crusted sediments with loose particles on top can exhibit mass flux rates about the same as for noncrusted sediments. Crusted sediments limit or eliminate sand drift in two conditions: for rough crusts that effect a sufficiently high threshold friction velocity (above the wind friction velocity) and for limited amounts of loose particles on the crust where particle supply is less than would be transported in normal saltation for a thick sandy surface. These "supply-limited" cases are similar to wind erosion of limited spilled material on a hard concrete surface. We quantified "supply limitation" by defining a "potential" or "supply unlimited" sand drift function Q = AG where A represents supply limitation that decreases as the particle source is depleted. Here Q is the mass of sand transported through a surface perpendicular to the ground and to the wind and having unit width during time period t, and G = Sigma u (sub *) (u (super 2) (sub *) - u (super 2) (sub *t ) ) dt for u (sub *) > u (sub *t) . G is integrated for the same time period t as for Q, u (sub *) is the friction velocity of the wind, and u (sub *t ) is the threshold friction velocity of the wind. Hard crusts (usually formed in the summer) tended to show almost no change of threshold friction velocity with time and often gave total protection from wind erosion. Rough crusts provided sufficient protection expressed as high threshold friction velocities. For these high threshold friction velocities, aeolian activity was greatly reduced or practically prevented. The softest crusts, usually formed in the winter, provided much less protection and sometimes were destroyed by the wind. Following this destruction the "potential" or "supply unlimited" sand drift would be observed. Copyright 2001 by the American Geophysical Union.

At least two types of heterogeneous reactions occur on the surface of these particles. Upon initial exposure of the oxide to NO (sub 2) there is a loss of NO (sub 2) from the gas phase by adsorption on the particle surface, i.e., NO (sub 2) (g) --> NO (sub 2) (a). As the reaction proceeds, a reduction of gaseous NO (sub 2) to NO, NO (sub 2) (g) --> NO (g) is found to occur. Initial uptake coefficients gamma (sub 0) for NO (sub 2) on the surface of these particles have been measured at 298 K using a Knudsen cell reactor coupled to a mass spectrometer. For the oxides studied, alpha ,gamma -Al (sub 2) O (sub 3) , alpha gamma -Fe (sub 2) O (sub 3) , TiO (sub 2) , SiO (sub 2) , CaO, and MgO, gamma (sub 0) ranges from < 4 X 10 (super -10) for SiO (sub 2) to 2 X 10 (super -5) for CaO with most values in the 10 (super -6) range. For authentic samples of China loess and Saharan sand, similar reactivity to the oxides is observed with gamma (sub 0) values of 2 X 10 (super -6) and 1 X 10 (super -6) , respectively. For HNO (sub 3) the reactivity is 1-2 orders of magnitude higher. Using these laboratory measurements, the impact of heterogeneous reactions of NO (sub 2) and HNO (sub 3) on mineral dust in tropospheric ozone formation and on O (sub 3) -precursor relationships is assessed using a time-dependent, multiphase chemistry box model. Simulations with and without heterogeneous reactions were conducted to evaluate the possible influence of these heterogeneous reactions on ambient levels. Results show that values of the initial uptake for NO (sub 2) and HNO (sub 3) , adjusted for roughness effects, must be greater than 10 (super -4) to have an appreciable impact on NO (sub x ) , HNO (sub 3) and O (sub 3) concentrations for the conditions modeled here. Thus the measured uptake coefficients for NO (sub 2) on dry surfaces are just below the lower limit to have an impact on the photochemical oxidant cycle, while the heterogeneous reactivity of HNO (sub 3) is sufficiently large to have an effect. Under conditions of high mineral dust mass loadings and/or smaller size distributions the importance of these reactions (both NO (sub 2) and HNO (sub 3) ) is expected to increase.

These measurements were performed during June 1998 in the North Atlantic within a significant CO (sub 2) sink. These direct estimates are in general agreement with the traditional geochemical isotope constraints. The covariance, or eddy correlation, technique directly measures the air-sea CO (sub 2) flux over hour timescales by correlating the fluctuations of CO (sub 2) with the turbulent vertical velocity fluctuations in the atmospheric surface layer. These measurements quantify the transfer of CO (sub 2) between the atmosphere and ocean over a range of wind speeds and improve the understanding of the environmental factors controlling the flux. The relatively large flux of CO (sub 2) in the study region, together with improved analytical techniques, facilitated the measurements. The half-hour mean wind speeds varied from 0.9 to 16.3 m s (super -1) over the month-long experiment. The mean pCO (sub 2) during the study period was -85.8 + or - 16.0 mu atm, and the mean covariance CO (sub 2) flux was estimated at 4.6 mol m (super -2) yr (super -1) . The average observed wind speed was 7.7 m s (super -1) . This is in close agreement with 3.9 mol m (super -2) yr (super -1) , the approximate CO (sub 2) flux based on (super 14) C parameterizations at this wind speed. At high winds, where the relationship between gas physical properties, surface processes, and air-sea gas exchange is still elusive, direct CO (sub 2) flux measurements are crucial. The measurements for winds in excess of 11 m s (super -1) show a general enhancement of gas transfer velocity over previous indirect measurements, and it is believed that this enhancement can be explained by the fact that the indirect methods cannot discriminate surface process variability such as atmospheric stability, upper ocean mixing, wave age, wave breaking, or surface films.

The parameterization uses six particle size divisions in the range 0.3-30 mu m radius, and all calculations are performed on each division independently, using the GCM's prognostic variables. The dust production scheme works within the GCM and includes dependencies on particle size distribution, soil moisture, vegetation, and friction velocity. Dust transport is carried out by the GCM's tracer advection scheme and includes vertical motion due to convection, gravitational settling, and turbulent mixing in the boundary layer. Wet and dry deposition processes are included within the GCM's precipitation schemes. Representative dust radiative parameters are incorporated into the GCM's two stream radiation code. Modeled monthly average near-surface dust concentrations are compared with observations: good agreement is seen in most locations, though the dust scheme tends to produce too little dust from China and too much from Australia in the southern spring. Global annual mean direct forcing due to the inclusion of dust in the GCM is +0.07 W m (super -2) at the top of the atmosphere (TOA) and -0.82 W m (super -2) at the surface. The geographical distributions of annual mean forcings are very inhomogeneous, with peak values exceeding the global means by a factor of approximately 2 orders of magnitude.

It is based on the SKIRON/Eta modeling system and the Eta/NCEP regional atmospheric model. The dust modules of the entire system incorporate the state of the art parameterizations of all the major phases of the atmospheric dust life such as production, diffusion, advection, and removal. These modules also include effects of the particle size distribution on aerosol dispersion. The dust production mechanism is based on the viscous/turbulent mixing, shear-free convection diffusion, and soil moisture. In addition to these sophisticated mechanisms, very high resolution databases, including elevation, soil properties, and vegetation cover are utilized. The entire system is easily configurable and transferable to any place on the Earth, it can cover domains on almost any size, and its horizontal resolution can vary from about 100 km up to approximately 4 km. It can run on one-way-nested form if necessary. The performance of the system has been tested for various dust storm episodes, in various places and resolution using gridded analysis or forecasting fields from various sources (ECMWF and NCEP) for initial and boundary conditions. The system is in operational use during the last two years, providing 72 hour forecasts for the Mediterranean region.

During 1998, two multifilter rotating shadow-band radiometers (MFRSRs), operated by Washington State University (WSU) and by the USDA UV-B program, were used to collect data on the Columbia Plateau atmosphere. Analysis of these data by an automated Langley algorithm provided retrievals for total optical thickness, allowing for calculation of aerosol optical thickness (AOT) and the top-of-atmosphere (TOA) instrument signal. Statistical evaluation of the TOA signal permitted recalculation of optical thickness using the Bouguer-Lambert-Beer law and resulted in improved estimates of aerosol optical thickness (AOT). Results for AOT and the associated Aangstroem parameters are presented here for an April 1998 dust event for two colocated Columbia Plateau sites. AOT at 500 nm went from background levels (seasonally dominated by regional windblown dust) of approximately 0.2 to more than 0.4 during the event maximum on April 27, not returning to normal levels until April 30. Comparison of 500-nm AOT between the two MFRSR showed a root-mean-square (RMS) difference of 0.016. The Aangstr:ouml;m exponent alpha reached a minimum of approximately 0.2, and the beta coefficient reached a maximum of approximately 0.35, both on April 27, coincident with the AOT maximum. Contemporaneous aerosol sampling in Spokane, Washington, provided (1) elemental data that strongly support our interpretation of this event as an influx of Asian dust without significant sulfur enrichment and (2) event maximum PM (sub 10) measurements approximately 80 mu g/m (super 3) consistent with Pullman event maximum AOT results, assuming a 3-4 km thick dust layer.

A new on-line dust tracer model coupled with a regional-scale meteorological model is developed and applied to this dust storm episode. The results for two large dust events that started during April 14-15 and 19-20, 1998, have been analyzed and discussed. The first dust storm was trapped in a cutoff vortex developed over the China plain. A modeled 3-D structure of dust associated with this cutoff vortex agreed with an observed time-height cross section of dust concentration. Results show that the strong subsidence at the backside of the vortex restricted the dust layer below 3 km level. Model analysis revealed that the second dust event that started during April 19-20 over inland China was the origin of a dust episode reported over North America. The trans-Pacific dust transport simulation successfully showed the dust onset near the West Coast of North America. Elevation of the dust layer during the long-range transport was below 3 km. The model is extended to include the transport of an Asian origin anthropogenic tracer over the North Pacific Rim. Both the natural-origin mineral dust and the Asian-origin anthropogenic tracer are simultaneously transported even if their emission regions are different.

The average dust concentration at these groundbased sites was 82 mu g m (super -3) ; this is lower than the lowest average concentration observed over the nine major Chinese deserts (arithmetic mean value of 270 mu g m (super -3) ), and it also is lower than that over the Loess Plateau (170 mu g m (super -3) ). The elemental mass-particle size distributions for several major dust-derived elements (Al, Ca, Fe, K, Mn, Si, and Ti) were approximately lognormal, but those for Al, Fe, and Ti differed from Ca, K, and Si. Dry deposition velocities calculated from the observed size distributions and a two-layer deposition model averaged 2.7 cm (super -1) for Al, Fe, and Ti. For Ca, K, and Si, which appear to be more strongly affected by local Tibetan sources, the average calculated dry deposition velocity was 4.3 cm s (super -1) . Wet deposition fluxes estimated from scavenging ratios indicate that less than 10% of the total deposition on the Tibetan Plateau is attributable to wet removal during the 9 months for which data are available. The yearly mean dust deposition rate (local plus remote and dry plus wet) is estimated to be of the order of approximately 100 g m (super -2) yr (super -1) , which is lower than that onto the Chinese desert regions (320 g m (super -2) yr (super -1) ) or the Loess Plateau (250 g m (super -2) yr (super -1) ), suggesting that the sources upwind of China, and the Tibetan Plateau itself, are not major sources for Asian dust.

Both data sets, comprising more than a decade of global, daily images, are commonly used to evaluate aerosol transport models. The present comparison is based on monthly averages, constructed from daily images of each data set for the period between 1984 and 1990, a period that excludes contamination from volcanic eruptions. The comparison focuses on the Northern Hemisphere subtropical Atlantic Ocean, where soil dust aerosols make the largest contribution to the aerosol load, and are assumed to dominate the variability of each data set. While each retrieval is sensitive to a different aerosol radiative property (absorption for the TOMS AI versus reflectance for the AVHRR AOT), the seasonal cycles of dust loading implied by each retrieval are consistent, if seasonal variations in the height of the aerosol layer are taken into account when interpreting the TOMS AI. On interannual timescales, the correlation is low at most locations. It is suggested that the poor interannual correlation is at least partly a consequence of data availability. When the monthly averages are constructed using only days common to both data sets, the correlation is substantially increased: this consistency suggests that both TOMS and AVHRR accurately measure the aerosol load in any given scene. However, the two retrievals have only a few days in common per month, so these restricted monthly averages have a large uncertainty. Calculations suggest that at least 7 to 10 daily images are needed to estimate reliably the average dust load during any particular month, a threshold that is rarely satisfied by the AVHRR AOT due to the presence of clouds in the domain. By rebinning each data set onto a coarser grid, the availability of the AVHRR AOT is increased during any particular month, along with its interannual correlation with the TOMS AI. The latter easily exceeds the sampling threshold due to its greater ability to infer the aerosol load in the presence of clouds. Whether the TOMS AI should be regarded as a more reliable indicator of interannual variability depends on the extent of contamination by subpixel clouds.

In contrast to nonabsorptive or weakly absorbing aerosols, the dust reflectance significantly decreases from the NIR to the blue because of the absorption of mineral particles in the visible. We chose simple but realistic vertical structures for the dust layer and examined the applicability of a set of aerosol size distributions and refractive indices with radiative properties computed from Mie theory. We found that 18 models (six aerosol size-refractive index distributions times three aerosol vertical distributions) were general enough to estimate the dust reflectance in the visible with an absolute RMS error of the order of 5%. We show that these dust models can be used within a "spectral matching algorithm" [Gordon et al., 1997] to effect atmospheric correction of ocean color imagery in dust-contaminated regions. We also found that our models all produce very similar top-of-atmosphere outgoing visible flux but that this flux may be significantly different from that predicted by other conventional dust models.

Observations were performed from December 1997 to November 1998, including during the Kamaseen storms of March 1998. A ground-based, manual Sun photometer was used to measure aerosol optical thickness (tau (sub a ) ) at four spectral bands in the 340-870 nm wavelength range (namely 340, 440, 675, 870). Total precipitable water vapor (W) was also measured simultaneously, based on the 936 nm channel measurements and extrapolations of the aerosol optical thickness from the neighboring 675 and 870 nm channels. Aerosol optical thickness ra tau (sub a) all the four spectral bands were very high (averaging 2.0-4.0) during the Kamaseen storms of late March 1998. Correspondingly, the Aangstroem wavelength exponent alpha of the optical thickness fell close to zero during that time, implying a substantial increase in dust. Overall, the monthly mean and median aerosol optical thickness were highest during January-May and lowest in June-October. During the January-May period total precipitable water vapor and Aangstroem exponent were lower than during the June-October period. There is a high correlation between the Aangstroem exponent and the optical thickness (r=0.63), with a ranging from 0.0 to 0.5 for tau (sub a) > 1.0, indicating high dust concentration. Trajectory analysis shows that the presence of dust was associated with air masses arriving predominantly from the Sahara or North Africa. No significant correlation was found between the optical thickness and the precipitable water vapor. These basic systematic observations are vital for assessing dust climatology in this important part of the world and also for validating satellite observations and dust transport models.

Retrievals are performed over a comparison space of four-component mixtures, selected from six commonly observed components having assumed, fixed microphysical properties but with mixing ratios free to vary from 0% to 100%. We refer to this approach, which assumes climatologically probable component particles and derives aerosol mixtures from the observations, as a "climatological retrieval." On the basis of simulated Multiangle Imaging Spectroradiometer (MISR) observations over dark water, the retrieval can distinguish mixtures containing large, spherical particles (sea salt), nonspherical particles (accumulation and coarse mode dust), and small, dark particles (black carbon) to within 20% or better of each component's true mixing ratio. This is sufficient to distinguish maritime from continental aerosol air masses. The retrievals, which use all nine MISR angles and the two wavelengths least affected by ocean surface reflectance (672 and 867 nm), are not good at distinguishing medium, spherical, nonabsorbing (sulfate) from medium, spherical, absorbing (carbonaceous) particles. However, the sum is retrieved to within 20% of the true mixing ratio or better. This is significantly more detail about the properties of particle mixtures than has previously been retrieved from satellite data, and in all cases, the derived total column aerosol optical depth remains well constrained, to at least 0.05 or 20%, whichever is larger. We expect the MISR data, with its frequent global coverage, to complement in situ and field data, which can provide greater detail about aerosol size and composition locally. This combined effort should advance our knowledge of aerosol behavior globally and our ability to model the impact of aerosols on the climatically important solar radiation budget.

Most of the dust uplifted from these deserts is carried by trade winds and deposited in tropical oceans with very little, if any, transported to polar regions. During glacial periods the dust concentrations in polar ice cores were a factor of 10 to 100 higher than during interglacial periods, including the current Holocene. The early general circulation model simulations of the past glacial climate were not able to reproduce these high mineral dust concentrations; the most recent attempts achieve an increased dust transport to polar regions by extending dust source areas to higher latitudes. We present a hypothesis that during glacial periods the Hadley cell is confined closer to the equator. This contraction of the Hadley circulation leads to the geographical change of the boundary between the tropical and the midlatitude circulation regimes. During the glacial periods a considerable fraction of the current tropical deserts was located outside the region of the Hadley circulation. This allowed the dust to be uplifted and transported by midlatitude storm systems to the polar regions. We present a model for the contraction of the Hadley circulation during the past glacial periods based on the Schneider-Lindzen and Held-Hou model of symmetric tropical circulation and on the assumption that the tropical sea surface temperatures were lower during glacial periods than they are today.

Recent observations through surface network exhibit that Asian dust took place more often in the western part of the Korean peninsula over the last 20 years. In this study, two dust cases, April 1998 and January 1999, were selected to examine detailed conditions most favorable for dust generation, emission, and transport to Korea and to investigate the effect of dust particles on physical and optical properties of aerosols collected in Seoul. Dust transported to the Korean peninsula is closely linked to dust storms generated in upstream regions of the Yellow River or Manzurian plain, which are known as main source regions. Judged from synoptic conditions for both spring and winter dust events, meteorological settings favorable for dust emission are high surface winds and baroclinic instability at 1.5 km level. A strong wind belt, formed at a 5 km level, expedites dust transport, and this is typically much faster in winter. It was confirmed from a backward trajectory analysis that the air carrying mineral dust particles originated from deserts in central Asia and in 1 day passed through the Korean peninsula during wintertime. The effect of mineral dust on aerosol particles is well depicted in the size-separated number concentrations of aerosols observed in Seoul. In both cases, concentrations of coarse particles larger than 0.82 mu m were distinctly enhanced while those of fine particle smaller than 0.5 mu m were reduced. The measurements of optical depth also indicate that the atmosphere is more turbid with larger particles during dust events. Copyright 2001 by the American Geophysical Union.

From a description of the soil characteristics and wind conditions, the DPM allows computation of the amounts of aerosol released and of their size distributions. Semiquantitative comparisons of the model outputs with the few field data available in the litterature validate its main implications. The first one is that the aptitude of a soil to release particles smaller than 20 mu m depends on (1) the dry size distribution of aggregates constituting its loose fraction, (2) its roughness length, and (3) the wind velocity. The second implication is that the size distribution of aerosols released in source areas also strongly depends on these parameters. Copyright 2001 by the American Geophysical Union.

By evaluating and removing the variable background in a digital SEM image using dynamic thresholding and then calculating the area and perimeter of each particle, one can study the relationship between particle area and particle shape. It is possible to distinguish in this manner between at least two different particle populations, separated by their fractal dimension, in a set of samples collected during 1 day in a heavy dust storm in Israel.

Both segments also have experienced recent volcanic eruptions which produced extensive, ephemeral, low-temperature, and diffuse hydrothermal venting. To study the geologic setting of these sites, high-resolution bathymetric surveys at eight locations on the CoAxial and Cleft segments were collected between 1993 and 1999. Two 675-kHz scanning sonar systems were used, Mesotech on the submersible Alvin and Imagenex on the remotely operated vehicle Jason. The bathymetry from these surveys can be gridded at a scale of 2-4 m and contoured at 1 m and thus can resolve many fine-scale features on the seafloor that are indistinguishable in multibeam bathymetry collected at the sea surface. Bathymetric data at this resolution are particularly useful for identifying geologic features related to diking, faulting, and lava flow emplacement. For example, the high-resolution bathymetric maps show that submarine fissure eruptions that form pillow lavas last long enough to become localized and to produce point source constructs along their length, and their extrusion rate is low enough that no significant drainback occurs. In contrast, lobate sheet flows are formed by short-lived, high-effusion rate eruptions in which no localization of output occurs along the eruptive fissure, and inflation is quickly followed by drainback, resulting in extensive collapse features. However, if the process of submarine lava flow inflation occurs at a slower rate and over a longer period of time, it can create lava rises up to 25 m high with distinctive structure and morphology. The scanning sonar data also show that fissures and grabens have formed or reactivated where dikes approach the surface adjacent to recent eruptive sites. The fine-scale bathymetry establishes that all the hydrothermal vent sites studied at the CoAxial and Cleft segments are located along prominent volcanic or tectonic extensional structures which provide the physical pathway for fluids from the subsurface to the seafloor. Furthermore, the fine-scale morphology of recent lava flows can be used as a qualitative indication of eruption duration. Copyright 2001 by the American Geophysical Union.

This hemispherical transport of airborne dust took place during a series of storms that developed during the first three weeks of April in a background of low-index circulation. These repeated events are studied through the combined analyses and interpretation of atmospheric data, ground-based aerosol measurements, visibility observations, AVHRR and Meteosat visible band satellite data, and the results of Eta model simulations, including an aerosol transport component. The observations produce a consistent picture of the temporal and spatial development of the dust events, whose main features are used in parts to verify the model results. The rate of dust suspension from some areas of the western Sahara desert exceeded 1.5 mg m (super -2) h (super -1) and the maximum column integrated dust load reached 2 g m (super -2) during April 3-5 1994, when the first major suspension event produced two simultaneous pulses of dust moving in opposite directions across the subtropical Atlantic Ocean and the eastern Mediterranean Sea. These dust suspensions were created by surface winds resulting from subsidence on the northeastern side of a blocking anticyclone in the Atlantic region and subsequent winds of an intense developing cyclone in the Mediterranean-African region. In the following period, maximum dust loads of 4.5 and 2.5 g m (super -2) occurred on April 12 and 17, respectively, when new cyclones transported dust across the Mediterranean from Africa to Europe. The generation of the two dust pulses during the first even and the recurrent cyclone transport in the following period is shown to be the result of a large-scale, anomalous atmospheric circulation connected with blocking in the Atlantic Ocean and the interactions of upper air jets downstream of the blocking. The particular state of the hemispheric circulation during the studied period corresponded to the positive phase of the North Atlantic Oscillation (NAO).

This late April 1998 event coincided with an episode of photochemical smog and reduced dispersion in the Lower Fraser Valley (LFV). Filter samples in the region show a massive injection of crustal elements (Si, Fe, Al, and Ca) with concentrations of Si approximately double those previously recorded. Ratios of these elements to Fe are shown to be statistically similar to ratios observed in mineral aerosol events in Hawaii and China. On the basis of the difference between observed and expected elemental concentrations and reconstructed soil mass in the episode, it is estimated that Asian dust contributed 38-55% to observed PM (sub 10) in the LFV, the remainder being attributed to local sources. Comparison of the April 1998 event with two spring meteorological analogs is consistent with this estimate. Mesoscale model simulations suggest that mineral dust was incorporated into the planetary boundary layer as a result of strong subsidence over the interior of southern British Columbia and Washington State which permitted interception of lower tropospheric elevated aerosol layers by surface-based mixing processes over mountainous terrain. Surface easterly ("outflow") winds then transported this material into the Lower Fraser Valley where it contributed significantly to total particulate loadings and an intense haze. This mechanism is consistent with the observed spatial and temporal distribution of PM (sub 10) . Copyright 2001 by the American Geophysical Union.

It is based on the atmospheric response to dust, extracted from midday Meteosat-IR imagery, and takes advantage of the impact of dust aerosols on the thermal infra-red radiance outgoing to space. Simulations show a quasi-linear relationship between satellite response to dust and shortwave optical depth, with a sensitivity depending on particle size distribution and radiative surface properties. Comparison of measured satellite response with photometric optical depth agrees with the simulations. Water vapor significantly affects the satellite signal for cases of large columnar amounts and oceanic air masses advected inland. Hence apart from possible coastal effects, the water vapor effect can be neglected in the Sahelian-Saharan zone north of the Intertropical Convergence Zone, coinciding with the major regions of African dust emission and transport. The construction of the IDDI involves the processing of reference images, theoretically representing the outgoing radiance obtaining under clear-sky conditions. Errors may arise from (1) dust remaining in the reference images and (2) seasonal shifts of the reference level; however, the latter error will be offset by averaging used in climatological processing. An error budget is presented for the station of Gao. A statistical comparison of IDDI data with visibility measured at synoptic stations results in (1) a validation of the product, and (2) a climatologically relevant visibility-IDDI relation, valid for the arid regions of northern Africa. The latter relation is consistent with both simulations and photometric measurements. IDDI maps over Africa compare successfully with optical depth over adjacent ocean regions derived from Meteosat-VIS imagery. The observed continuity of dust plumes across the African coast demonstrates the consistency between both products. Copyright 2001 by the American Geophysical Union.

Huge Asian dust events that occurred in the middle of April 1998 were captured by this network. In this paper we present the organization of the network; a description of the instruments, including the lidar, sky radiometer, and optical particle counter; and the results of the observation, and offer discussions regarding the transport mechanism of Asian dust in east Asia using an on-line tracer model. We discussed the time series of the surface concentration and the height distribution of the dust. A cutoff cyclone generated during the dust episode was responsible for trapping and sedimentation during the transportation of the Asian dust, particularly in the southern parts of China and Japan. Horizontal dust images derived from NOAA/AVHRR clearly revealed the structure of the vortex. The lidar network observation confirmed the general pattern of dust height distribution in this event; the height of the major dust layer was about 3 km over Japan but was higher (4 to 5 km) in Seoul and Hefei. A thin dust layer in the upper troposphere was also commonly observed in Hefei and Japan. Evidence of the coexistence of dust and cirrus was shown by the polarization lidar. The lidar network observation of Asian dust and satellite remote sensing provide key information for the study of the transport mechanism of Asian dust. Further extension of the lidar network toward the interior of the continent and the Pacific Rim would reveal the greater global mechanism of the transportation.

The two measurement methods have a complementary sensitivity to variety of dust properties. The methodology is demonstrated using spectral measurements (0.47-2.21 mu m) from Landsat TM over the bright Senegalian coast and dark ocean, and Aerosol Robotic Network (AERONET) radiances measured in several locations. We derive (1) the dust size distribution, showing a dominant coarse mode at 1-5 mu m and a secondary mode around 0.5 mu m effective radius; (2) dust absorption, which is found to be substantially smaller than reported from previous measurements; (3) the real part of the refractive index which varies within the range 1.53-1.46; and we show that (4) the effect of the dust nonspherical shape on its optical properties is not significant for scattering angles <120 degrees .

The analysis shows that the particles were mostly aggregates of varying mineralogical composition rather than pure minerals. It is also shown that sulfur (not associated with gypsum) and, to a lesser extent, iron tended to reside on the particles' surface, while Ca, Mg, K, Al, and Si were all an integral part of the particles. The lack of NaCl and sulfuric acid aerosols in the sample indicates that the air mass did not interact with marine air or with clouds. This conclusion is further supported by back trajectory calculations. These findings suggest that the sulfur in the aerosols did not result from atmospheric processes but rather originated from processes in the source region. Black residue, surrounding some of the particles, suggests the possible existence of organic matter in the sample, probably originating from biological activity in the soil at the source of the particles. The method of individual particle analysis provides important information about the composition and morphology of the particles, information that otherwise cannot be obtained by bulk analysis methods.

In addition, the deposition flux of dustfall was measured throughout Israel and in the Sinai Desert during the years 1970-1973. TSP concentrations during dust pulses ("episodes") were from 10 to 120 times higher than the background values of approximately 100 mu g m (super -3) ; the maximum concentration measured was 24,000 mu g m (super -3) . The annual deposition flux (from pulses only) decreased from 90 g m (super -2) yr (super -1) in the south to 30 g m (super -2) yr (super -1) in the north. The local contribution to the annual deposition flux was approximately 50% in the south and near the Judean Desert in the east but decreased to 25% in the north. Deposition velocities of the dustfall during months without dust episodes were on the order of 1.0 cm s (super -1) , while during months when dust storms occurred, deposition velocities are from 2 to 6 times greater than the background, depending on the location. Monthly mean deposition velocities during dust episodes varied between 2.6 cm s (super -1) and 9.0 cm s (super -1) ; short term (1 hour) values up to 27 cm s (super -1) have been measured.

Time series over Algeria, Libya, and Israel yield the following findings: The peak values in both surface concentrations and TOMS data suggest that AI values of 2.5 and 1.2 correspond to surface mean daily concentrations of 1900 and 1000 mu g/m (super 3) respectively. Surface concentrations and TOMS maps show that AI values of 3.0 correspond to about 4000 mu g/m (super 3) . TOMS AI maximum values were found to increase from Algeria to Israel moving along with the center of the dust plume from 0.9 to 2.1 and 2.5 AI values. This seems to be in contradiction with the fact that the plume moves farther away from the major mineral dust sources over the Sahara and may be caused by either an increased vertical extension of the plume, hence increasing the TOMS AI, or due to convergence of the dust plume over the eastern Mediterranean. The size distribution, morphological, and mineralogical composition of the dust analyzed in this study, as well as other aerosol parameters, are essential for improving the remote sensing methods such as the TOMS AI algorithms. Of course, surface measurements alone do not allow the refinement of the TOMS retrievals; vertical profile dust measurements as well as other physical and optical aerosol parameters are necessary.

Data from the broadband radiometers suggests that the perturbation to the top of the atmosphere net solar irradiance is as strong as -60 W m (super -2) + or -5 W m (super -2) during the dust events. In situ measurements with the nephelometer and particle soot absorption photometer suggest that the single scattering albedo is approximately 0.87 at a wavelength of 0.55 mu m. This is in agreement with the optical parameters calculated from independent measurements of the particle size distributions combined with suitable refractive indices and Mie-scattering theory. The wavelength dependence of the extinction coefficient derived from measurements of the scattering coefficient by the nephelometer is also in excellent agreement with the calculations. Independent surface-based measurements from Cape Verde suggest that the wavelength dependence of the aerosol optical depth appears reasonable. Calculations of the downward solar irradiances within the aerosol layer are generally in good agreement with the measurements demonstrating consistency between the measurements and the modeling efforts. The terrestrial radiative effect is not detectable by the current instrumentation, though it cannot be considered negligible. These measurements suggest that satellite retrieval algorithms may misclassify the aerosol outbreak as cloud because the aerosol optical depth at 0.55 mu m is as high as 1.15, which is in excess of the thresholds used in some cloud detection algorithms. The measurements demonstrate that this method could be used to provide an accurate benchmark for satellite-based estimates of the radiative effect of aerosols.

The study covers a 2-week period of strong dust storms in April 1998 in the major dust source area of East Asia. The modeled surface winds at grid resolutions of 20, 40, 60, and 80 km are verified against observational data. At all resolutions the model has a positive bias in wind speed that decreases as resolution increases. Dust fluxes that are proportional to the fourth power of the friction velocity (u (sub *) ) and the third power of the wind speed are calculated at all four resolutions and compared. Compared with the 20-km resolution u (sub *) -driven flux, which is deduced to be the most accurate, the u (sub *) -driven flux on the coarser grids overestimate the flux, with the 80 km being 60% higher for individual events and nearly 20% higher in the total dust production for the entire study period. The wind-driven flux misses the smaller events due to the lack of a dependence on stability and wind shear, when compared with the timing of surface dust observations, and has differences of up to 70%, when compared with the 20-km u (sub *) -driven flux. Averaging over space and time tends to reduce the differences among grids and might support modeling at coarse resolution. Copyright 2001 by the American Geophysical Union.

Industry analysts project that photovoltaic sales will increase from their current $1.5 billion level to over $27 billion by 2020, representing an average growth rate of 25%. (Cook et. al. 2000)[1]. To date, the vast majority of sales have been for navigational signals, call boxes, telecommunication centers, consumer products, off-grid electrification projects, and small grid-interactive residential rooftop applications. Building integrated photovoltaics, the integration of photovoltaic cells into one or more of the exterior surfaces of the building envelope, represents a small but growing photovoltaic application. In order for building owners, designers, and architects to make informed economic decisions regarding the use of building integrated photovoltaics, accurate predictive tools and performance data are needed. A building integrated photovoltaic test bed has been constructed at the National Institute of Standards and Technology to provide the performance data needed for model validation. The facility incorporates four identical pairs of building integrated photovoltaic panels constructed using single-crystalline, polycrystalline, silicon film, and amorphous silicon photovoltaic cells. One panel of each identical pair is installed with thermal insulation attached to its rear surface. The second paired panel is installed without thermal insulation. This experimental configuration yields results that quantify the effect of elevated cell temperature on the panels' performance for different cell technologies. This paper presents the first set of experimental results from this facility. Comparisons are made between the electrical performance of the insulated and non-insulated panels for each of the four cell technologies. The monthly and overall conversion efficiencies for each cell technology are presented and the seasonal performance variations discussed. Daily efficiencies are presented for a selected month. Finally, plots of the power output and panel temperatures are presented and discussed for the single-crystalline and amorphous silicon panels.

Architects and building owners need these tools in order to determine if the potential energy savings realized from building integrated photovoltaics justifies the additional capital expenditure. The National Institute of Standards and Technology (NIST) seeks to provide high quality experimental data that can be used to develop and validate these predictive performance tools. The temperature of a photovoltaic module affects its electrical output characteristics and efficiency. Traditionally, the temperature of solar cells has been characterized using the nominal operating cell temperature (NOCT), which can be used in conjunction with a calculation procedure to predict the module's temperature for various environmental conditions. The NOCT procedure provides a representative prediction of the cell temperature, specifically for the ubiquitous rack-mounted installation. The procedure estimates the cell temperature based on the ambient temperature and the solar irradiance. It makes the approximation that the overall heat loss coefficient is constant. In other words, the temperature difference between the panel and the environment is linearly related to the heat flux on the panels (solar irradiance). The heat transfer characteristics of a rack-mounted PV module and a BIPV module can be quite different. The manner in which the module is installed within the building envelope influences the cell's operating temperature. Unlike rack-mounted modules, the two sides of the modules may be subjected to significantly different environmental conditions. This paper presents a new technique to compute the operating temperature of cells within building integrated photovoltaic modules using a one-dimensional transient heat transfer model. The resulting predictions are compared to measured BIPV cell temperatures for two single crystalline BIPV panels (one insulated panel and one uninsulated panel). Finally, the results are compared to predictions using the NOCT technique.

Sharks were exposed to normoxic and three levels of hypoxic conditions. Under normoxic conditions (5.5-6.4 mg l super(-1)), shark routine swimming speed averaged 25.5 and 31.0 cm s super(-1) for obligate ram-ventilating S. tiburo and C. acronotus respectively, and 25.0 cm s super(-1) for buccal-ventilating M. norrisi. Routine oxygen consumption averaged about 234.6 mg O sub(2) kg super(-1) h super(-1) for S. tiburo, 437.2 mg O sub(2) kg super(-1) h super(-1) for C. acronotus, and 161.4 mg O sub(2) kg super(-1) h super(-1) for M. norrisi. For ram-ventilating sharks, mouth gape averaged similar to 1.0 cm whereas M. norrisi gillbeats averaged 56.0 beats min super(-1). Swimming speeds, mouth gape, and oxygen consumption rate of S. tiburo and C. acronotus increased to a maximum of 37-39 cm s super(-1), 2.5-3.0 cm, and 496 and 599 mg O sub(2) kg super(-1) h super(-1) under hypoxic conditions (2.5-3.4 mg l super(-1)), respectively. M. norrisi decreased swimming speeds to 16 cm s super(-1) and oxygen consumption rate remained similar. Results support the hypothesis that obligate ram-ventilating sharks respond to hypoxia by increasing swimming speed and mouth gape while buccal-ventilating smoothhound sharks reduce activity.

S. A. ), Puerto Rico, Costa Rica-Panama, and Queensland (Australia) through two sources of data: output from the National Center for Environmental Prediction "reanalysis system' and area-averaged station data. The reanalysis system merges observations from airplanes, land stations, satellites, ships, and weather balloons with output from a weather-forecast model to create global fields of atmospheric variables. Station data consisted of temperature and precipitation measured with thermometers and rain gauges at fixed locations. Temperatures were near normal in Colorado when the amphibian declines occurred in the 1970s, whereas in Central America temperatures were warmer than normal, especially during the dry season. The station data from Puerto Rico and Australia indicated that temperatures were above normal during the period of amphibian declines, but reanalysis did not show such a clear temperature signal. Although declines occurred while the temperature and precipitation anomalies in some of the regions were large and of extended duration, the anomalies were not beyond the range of normal variability. Thus, unusual climate, as measured by regional estimates of temperature and precipitation, is unlikely to be the direct cause of amphibian declines, but it may have indirectly contributed to them. Previous researchers have noted that the declines appear to have propagated from northwest to southeast from Costa Rica to Panama and from southeast to northwest in Queensland, Australia. Wind has the potential to transport pathogens that cause amphibian mortality. The mean direction of the near-surface winds tended to parallel the path of amphibian declines from July-October in Central America and from May-July in Australia. The wind direction was highly variable, however, and the propagation rate of amphibian declines was much slower than the mean wind speed. In addition, the most likely pathogen is a chytrid fungus that does not produce desiccation-resistant spores. Thus, if wind is involved in the propagation of amphibian declines, it is through a complex set of processes.

The effects of El Nino-Southern Oscillation (ENSO) are linearly removed from the OLR to isolate the predictive utility of subseasonal variations in tropical convection. A single canonical correlation (CCA) mode accounts for most of the predictable signal. The rank correlation between this mode and observed rainfall anomalies over southern California is 0.2 for a 2-week lag, which is comparable to correlation between a weekly ENSO index and weekly rainfall in this region. This corresponds to a doubling of the risk of extreme rainfall in southern California when the projection of tropical OLR on the leading CCA mode two weeks prior is extremely large, as compared with times when it is extremely small. "Extreme" is defined as being in the upper or lower quintile of the probability distribution. The leading CCA mode represents suppressed convection in the equatorial Indian Ocean and enhanced convection just south of the equator east of the date line. OLR regressed on the time series of this mode shows an eastward progression of the suppressed region to just south of the Philippines at the time of maximum California rainfall enhancement. The region of enhanced convection east of the date line remains quasi stationary. Associated with this tropical OLR evolution is the development of upper-tropospheric westerly wind anomalies near 30 degree N in the eastern Pacific. Synoptic-scale weather systems are steered farther east toward California by these enhanced westerlies. Because most operational weather prediction models do not accurately simulate subseasonal variations in tropical convection, statistical prediction models such as the one presented here may prove useful in augmenting numerical predictions. An analysis of 4 yr of operational week-2 ensemble predictions indicates that the level of skill provided by the statistical model is comparable to that of the operational ensemble mean. Given that by week 2 the operational forecast model has lost its ability to represent convectively coupled circulation associated with the subseasonal tropical convective variability, the statistical model provides essentially independent information for the forecaster.

Two major species groupings, estuarine dependent species (e.g., red drum, Sciaenops ocellatus; spot, Leiostomus xanthurus; and Atlantic croaker, Micropogonias undulatus) and coastal species, (e.g., king mackerel, Scomberomorus calvalla; Spanish mackerel, Scomberomorus maculatus; and bluefish, Pomatomus saltatrix) are most likely to be influenced by riverine discharge. While riverine enhancement of fishery production seems clear, the exact mechanisms through which this occurs are not. Because recruitment makes the greatest contribution to fish stock biomass, it is by enhancing recruitment that fishery production is influenced most. Waters influenced by the river discharge are a rich environment where both physical dynamics, (e.g., hydrodynamic convergence, water column stratification, and transport and retention of fish larvae) and biological dynamics (e.g., primary and secondary production and larval fish production, feeding, growth, and predation) may favor processes that regulate survival and recruitment.

Data are used from three dispersion experiments conducted at the Cape Canaveral Air Station as part of the US Air Force's Model Validation Program. A total of 79 half-hour-averaged ground-level concentrations of tracer-gas from 11 near-surface tracer releases during unstable and near-neutral conditions are simulated. A result of this study is that a large difference is not seen in the results between the use of a horizontally uniform wind observed at the tracer release site and horizontally variable wind for puff trajectory calculations. The uniform wind gives a slightly more accurate average result, but only because the uniform wind (observed near the shoreline) has greater speed than the variable wind field. The puff-transport wind speed for the variable wind case would be increased if the effects of vertical wind shear are taken into account. It is shown that for unstable conditions, including near-neutral conditions, the assumption of rapid vertical mixing leads to an under prediction (negative bias) of the maximum ground-level concentrations by about a factor of 2.3 with a typical factor of about 11 scatter between predicted and observed values. If a less rapid vertical mixing is assumed, then the overall predictions equal the overall observations, i.e., near-zero bias with a typical factor of scatter of about 3.6. If the near-neutral data are removed from the evaluation statistics, then the assumption of rapid vertical mixing leads to an overprediction by a factor of about 0.03 with a scatter factor of about 4; the assumption of less rapid mixing leads to an overprediction by a factor of about 0.55 with a scatter factor of about 3. These results are consistent with the fact that on-shore flows are less turbulent than flows over land for the same stability class.

They appear as leading empirical orthogonal functions (EOFs) of 500-hPa height or 200-hPa streamfunction anomalies and are found from intraseasonal to decadal time scales. Both patterns exhibit wave 3 hemispheric patterns in mid to high latitudes, and a well-defined wave train with large amplitude in the Pacific-South American (PSA) sector. Therefore, they are referred to as the PSA modes (PSA1 and PSA2). PSA1 is related to sea surface temperature anomalies (SSTAs) over the central and eastern Pacific at decadal scales, and it is the response to El Nino-Southern Oscillation (ENSO) in the interannual band. The associated rainfall summer pattern shows rainfall deficits over northeastern Brazil and enhanced rainfall over southeastern South America similar to rainfall anomalies during ENSO. PSA2 is associated with the quasi-biennial component of ENSO, with a period of 22-28 months and the strongest connections occur during the austral spring. The associated rainfall pattern shows a dipole pattern with anomalies out of phase between the South Atlantic Convergence Zone (SACZ) extending from central South America into the Atlantic and the subtropical plains centred at 35 degree S. These two modes are also apparent in tropical intraseasonal oscillations for both summer and winter. Eastward propagation of enhanced convection from the Indian Ocean through the western Pacific to the central Pacific is accompanied by a wave train that appears to originate in the convective regions. The positive PSA1 pattern is associated with enhanced convection over the Pacific from 150 degree E to the date line. The convection pattern associated with PSA2 is in quadrature with that of PSA1. Both PSA modes are influenced by the Madden Julian Oscillation and influence rainfall over South America.

In addition, sediment manipulations typically used for homogenization and dosing in bioaccumulation assays were compared. Rather than an asymptotic approach to steady state, both resident and dosed PAH accumulation exhibited a peak during the 14-d assays, with steeper declines being noted for the lower-molecular-weight compounds. Lack of evidence of a peak for higher-molecular-weight PAHs may be due to slower kinetics and the short length of the assay. Relative to minimally mixed sediment, slurried sediment enhanced the accumulation of less-soluble resident PAHs, did not affect moderately soluble PAHs, and reduced the uptake of the more-soluble PAHs, fluorene and phenanthrene. Aging sediment after mixing reduced the availability of highly to moderately soluble resident PAHs but had no effect on less-soluble PAHs. A similar effect was noted for dosed PAHs, though a larger reduction in bioavailability was observed. Dosed PAH uptake clearance coefficients (k sub(s)) exceeded those of minimally mixed resident PAHs by factors of 3 to 4 for pyrene and 26 for benzo[a]pyrene. These results demonstrate that sediment manipulations and contamination history need to be considered when measuring PAH bioaccumulation.

Salt Marsh AN - 18167638; 5174135 AB - Diet composition of mummichogs, Fundulus heteroclitus, from three marsh habitats (creeks, pools, and marsh surface) within tidally restored and an adjacent unrestricted (reference) region of Sachuest Point salt marsh (Middletown, RI, U.S.A.) was examined. Major diet components were detritus, copepods, diatoms, insects (larvae and adults), ostracods, and chironomids. Total length, wet weight, and gut fullness of mummichogs were equivalent within habitats between the restoring and unrestricted marshes. Diet composition and percent abundance of diet items were also similar within habitats between the unrestricted and restoring marshes. However, differences in diet patterns were observed among habitats (creeks, pools, and marsh surface) within each marsh. Fish collected from creeks had fuller guts than those sampled from the marsh surface for both the restoring and unrestricted marsh. Diet composition also differed among marsh habitats, but only within the restoring marsh. In the restoring marsh, fish sampled from the creeks consumed primarily detritus, diatoms, and ostracods, whereas fish from the pools consumed mainly detritus, copepods, chironomids, and insects. Differences in diet composition among habitats were most likely a reflection of prey availability. This study provides evidence that tidally restored marshes can provide similar food resources as unrestricted marshes, in terms of consumption patterns of dominant marsh consumers, within the first year after restoration, before major shifts in dominant vegetation (i.e. from Phragmites australis to Spartina spp.) occur.

The estimation requires no detailed knowledge of the area's meteorology, but presumes it is unchanged in the future. However, the climate seldom remains static. Numerous climate forecasts of meteorological probabilities over extended periods are now available. It is possible to use these meteorological forecasts directly in the estimation of storm frequencies from the historical record. A heuristic approach is defined here to estimate storm frequencies that recognize forecasts of extended weather probabilities. Basically, those groups of historical meteorological record segments matching forecast meteorological probabilities are weighted more than others, during the estimation of storm frequencies. (Affiliated groups of hydrologic record segments may be similarly weighted for hydrological estimation; e.g., flood frequency estimation.) An example of frequency estimation is made for maximum annual daily flow, using currently available agency meteorological forecasts in the United States and Canada.

Travel distance of particles is probably limited by trapping in bars, which have a longitudinal spacing proportional to channel width. Increased abundance of woody debris reduces bar spacing and may reduce L sub(b). Longer cumulative duration of bed load transporting flows in a year appears to increase L sub(b). Other predictors of annual travel distance such as stream power per unit length, drainage area and bankfull discharge were less well correlated with L sub(b) (r super(2) ranging from 0 times 27 to 0 times 51). Stream power per unit bed area, basal shear stress and slope were not significantly related to L sub(b) (r super(2) < 0 times 05). Most correlations were improved when regressions were limited to data from the west coast USA. Travel distance estimates can be used to help identify reaches that may take longer to recover from large, short-term increases in sediment supply.

The parasite was originally discovered in a single American eel captured in Winyah Bay, South Carolina, in 1995. We examined eels from all major coastal rivers in North Carolina and recorded prevalence and mean intensity of infection. A total of 1111 eels were captured. Overall 52% were infected (prevalence ranged from 26-100% among rivers), and there were 1-53 nematodes per infected individual (mean intensity = 3.9). The condition of infected eels was not significantly different from that of uninfected eels; however, we found a significant positive relationship between mean intensity of infection and eel size. The infection rate of North Carolina eels was substantially higher than that reported in Chesapeake (10-29%) and Hudson River (0-12%) collections. The high infection rates we observed could be related to increased warm water periods in southern rivers or the fact that this exotic may have been introduced earlier in southern rivers than in northern ones.

Global reanalysis data as well as atmospheric general circulation model (AGCM) simulations are used for this purpose. For the observational analysis, 53 yr of NCEP reanalyses are stratified into El Nino, La Nina, and neutral winters [Jan-Feb-Mar (JFM)]. The AGCM analysis is based on three sets of 180 seasonal integrations made with prescribed global sea surface temperatures corresponding to an observed El Nino event (JFM 1987), an observed La Nina event (JFM 1989), and climatological mean JFM conditions. These ensembles are large enough to estimate the ENSO-induced changes of variability even in regions not usually associated with an ENSO effect. The focus is on the anomalous variability of precipitation and 500-mb heights. The most important result from this analysis is that the patterns of the anomalous extratropical height variability change sharply from the synoptic to the intraseasonal to monthly timescales, but are similar thereafter. In contrast, the patterns of the anomalous tropical rainfall variability are nearly identical across these timescales. On the synoptic and monthly scales, the anomalous extratropical height variability is generally opposite for El Nino and La Nina, and is also roughly symmetric about the equator. On the intraseasonal scale, however, the anomalous height variability is of the same sign for El Nino and La Nina in the Atlantic sector, and is antisymmetric about the equator in the Pacific sector. In the North Pacific, these intraseasonal variance anomalies (which are consistent with a decrease of blocking activity during El Nino and an increase during La Nina) are of opposite sign to the monthly and seasonal variance anomalies. The sharp differences across timescales in the ENSO-induced changes of extratropical variability suggest that different dynamical mechanisms dominate on different timescales. They also have implications for the predictability of extreme events on those timescales. Finally, there is evidence here that these impacts on extratropical variability may differ substantially from ENSO event to event, especially in the northern Atlantic and over Europe.

We estimated the potential impacts of elevated surface temperatures on ecological processes of growth, conversion efficiency, and behavior in early juvenile sablefish. Growth experiments tested a wide range of temperatures from 6 to 24 degree C, with fish receiving ad libitum or low (3% body weight d super(-1)) rations. With unlimited food, growth increased rapidly as temperature increased to 14 degree C, then displayed a more gradual rise to 22 degree C. Growth rates at the warmer temperatures were among the highest recorded for teleosts, attaining a maximum of 3.3 mm d super(-1) in length and a specific growth in weight of 11.8%. A similar response to temperature was observed at low rations, although at lower overall growth rates. At 24 degree C, there was a severe decline in growth for both ration levels, and few fish survived the 3 wk experiments. Gross growth efficiency, measured at temperatures of 6 to 22 degree C, displayed an interactive effect of temperature with ration level consistent with bioenergetic relationship. Conversion peaked at 16 to 20 degree C for fish receiving ad libitum rations, and at 10 degree C for fish on restricted rations. Conversion rates of sablefish were comparable to those calculated for a diverse array of fish species, suggesting that the rapid growth rates are driven by high consumption rather than unusually efficient energy transfer. Experiments analyzing sablefish behavior in thermally stratified water columns demonstrated increasing movement into colder water as ration level decreased, in agreement with an energy conserving strategy.

Unlike many dinoflagellates, A. operculatum has a naturally high division rate of approximately 1 division day super(-1), which yields a nearly synchronous population, making it useful for population studies. When grown on a 16:8 h light/dark cycle, S-phase begins 10 h and mitosis 14-16 h after the onset of light, as determined by flow cytometry. Alterations in the timing of the dark/light and light/dark transitions showed that the cell cycle is entrained by the dark/light transition, with the light/dark cue being uninvolved. Cells in logarithmic phase growth also undergo diel changes in cell size (9-14 mu m), reaching a maximum size late in the light phase, concurrent with mitosis. Stationary phase cells or cells blocked in G1 of the cell cycle with a cell cycle inhibitor, olomoucine, showed no size changes or reduced size changes over the diel cycle, suggesting a coupling of cell size to the cell division cycle. In Euglena, cAMP-dependent signaling appears to mediate diel phasing of the cell cycle. Therefore, the role of cAMP in cell cycle control in A. operculatum was investigated. Measurement of intracellular cAMP by radioimmunoassay (RIA) revealed that cAMP concentrations varied on a diel basis, but increases observed appeared to correlate with cell size increases, and did not correlate with light cues at the dark/light or light/dark transition. However, when cells were treated with the cAMP phosphodiesterase inhibitor, IBMX, cell cycle progression was inhibited at both the G1/S and the G2/M phase transitions. This supports a role for cAMP-dependent signaling in the dinoflagellate cell cycle and is in agreement with the documented role of cAMP in the cell cycle control of higher eukaryotes.

These models require assumptions about the form of the growth curve. We used the Schnute general growth model to examine growth in the Pacific Blue Mussel, Mytilus trossulus, in Prince William Sound, AK. The Schnute model provides a convenient analytical method for selecting among all previously published growth models. Mussels were tagged with individually numbered tags at 13 sites in July 1997 and were collected in July 1998. Age was determined from surface growth rings on the shell, and shell length at maximum annulus was measured. Annual deposition of the growth rings was verified through radial sections of mussel valves, aided by acetate peels, in conjunction with in situ annual growth measurements. Growth was modeled with the Schnute general growth model for age-length data or with an analog of the Schnute model for growth-increment data. Bootstrap confidence intervals were obtained for all parameters of the model and for model predicted lengths at each annulus. Confidence intervals of the between-annuli growth-increment model overlapped those of the age-length model at all annuli when growth over the entire range of ages in the population was estimated. Differences in growth model parameters between the age-length model and the mark-recapture analog could be accounted for solely by inherent differences in age-based versus length-based models.

In general, mussel growth at our sites was best described by the von Bertalanffy submodel.

Compared with the generally low activity of the previous 24 years (1971 to 1994), the past 6 years have seen a doubling of overall activity for the whole basin, a 2.5-fold increase in major hurricanes ( greater than or equal to 50 meters per second), and a fivefold increase in hurricanes affecting the Caribbean. The greater activity results from simultaneous increases in North Atlantic sea-surface temperatures and decreases in vertical wind shear. Because these changes exhibit a multidecadal time scale, the present high level of hurricane activity is likely to persist for an addition similar to 10 to 40 years. The shift in climate calls for a reevaluation of preparedness and mitigation strategies.

AN - 36409598; 8880 AB - PURPOSE: The implementation of a fifth amendment to the management plan for rock the shrimp fishery in the South Atlantic Exclusive Economic Zone (EEZ) is proposed. The fishery is affected by unregulated commercial fishing, significant bycatch, lack of consistent regulations, noncompliance to regulations by fishermen participating in a transboundary penaeid shrimp fishery, the potential for release of exotic species, habitat alteration due to human activities, incomplete and inadequate data on the status of the fishery, excess fishing capacity, excessive logging, and little incentive for conservation and regulatory compliance. Issues identified during scoping include compliance incentives, excessive harvest, reduction in ecosystem diversity, release does exotic species and or diseases and parasites, habitat alteration and inadequate data for S. Atlantic rock shrimp fishery. Alternatives, including a No Action Alternative, are considered in this draft EIS. Under the proposed action, the amendment would establish a license limitation program for the fishery within the South Atlantic Fishery Management Council's jurisdiction and limit initial eligibility to boat owners/vessels that have held a valid rock shrimp permit prior to December 31, 1999, and can demonstrate landings of at least 15,000 pounds in any one year from 1996 to 1999; require captains operating permitted vessels fishing for rook shrimp in the EEZ to have a vessel operator's permit issued by the National marine Fisheries Service; require the minimum allowable mesh size for a trawl used to fish in the EEZ to be 1-and-7 /8th-inch stretched mesh; require that any vessel fishing for rock shrimp in the EEZ must use an approved vessel monitoring system, the cost of which would not exceed $2,500 for equipment and installation; and require that the foregoing management measures would apply to all vessels fishing in the EEZ. POSITIVE IMPACTS: In general, the amendment would assist in the protection of the rock shrimp stock, while protecting the economic interests of vessel owners. Owners of vessels that qualify for a limited entry permit would probably log additional quantities of shrimp. The permit process would improve compliance with fishery management regulations. NEGATIVE IMPACTS: The limited entry program could result in short-term loss of revenue for owners of 102 vessels and their crews. Permit requirements, gear limitations, and monitoring system could increase operating expenses for vessel owners. Limitations in place following the passage of the amendment would place some constraints on the social life of the affected fishermen. LEGAL MANDATES: Coastal Zone Management Act of 1972, as amended (16 U.S.C. 1451 et seq.), and Magnuson Fishery Conservation and Management Act of 1976 (16 U.S.C. 1801).

These tags recorded water temperatures experienced by the fish for periods of 62 to 118 d at resolutions of 15 to 30 min. We considered fine-scale aspects of the data by analyzing diel temperature patterns in regard to the migration behavior and orientation of the fish. During the night, temperatures experienced by the fish changed little, and were among the highest temperatures experienced whereas daytime temperatures often showed dramatic changes as the fish changed depth. We analyzed a time series of temperature differences between sunrise and sunset as an indication of progress made by the fish against horizontal thermal gradients, which was assumed to represent changes in latitudinal position. Daytime differences were positive when the fish were migrating to warmer waters, whereas night-time differences were zero or slightly negative. This suggests that the fish made more progress migrating during the day than at night. We also considered large-scale aspects by examining oceanographic data in relation to the temperatures recorded by the tags. Analysis of possible migration routes based on large-scale patterns of sea surface temperature distributions suggests that zonal (east-west) routes are preferred. These data support the hypothesis that chum salmon utilize orientation cues associated with the sun during open ocean migration. However, whether salmon also utilize additional orientation or navigation mechanisms remains to be determined.

Combining these data with neon data, we have derived the isotopic ratio (R (sub t ) ) of the nonatmospheric part of helium (terrigenic helium). The calculated R (sub t ) values are significantly lower than helium isotope ratios from mid-ocean ridge (MOR) sources (R (sub MOR) nearly equal 8R (sub a ) ; R (sub a ) := ( (super 3) He/ (super 4) He) (sub air) ), which are generally presumed to dominate the isotope characteristics of helium of nonatmospheric origin. For the depths most influenced by the southern East Pacific Rise (EPR) helium plume the isotopic ratio of terrigenic helium is approximately 7.4 R (sub a ) . However, both the northern EPR plume and the Juan de Fuca Ridge (JdFR) plume show significantly lower R (sub t ) values of approximately 6.8 R (sub a ) . We find minimum R (sub t ) values of approximately 5.6 R (sub a ) at about 20 degrees N to 30 degrees N from 2000 m depth to the ocean floor. We conclude that in addition to the EPR and JdFR helium sources (having MOR isotope characteristics) there is a flux of radiogenic (super 4) He out of deep-sea sediments and the oceanic crust which causes a significant deviation of R (sub t ) toward values lower than R (sub MOR) . Using our calculated terrigenic (super 4) He concentrations and isotope ratios R (sub t ) and the helium isotope ratios of the two end-members (MOR helium and crustal helium), we derive concentrations and ocean bottom fluxes of crustal (super 4) He ( (super 4) He (sub crust) ). Maximum concentrations of (super 4) He (sub crust) (up to approximately 30 pmol kg (super -1) ) are found at about 20 degrees N to 30 degrees N between 2000 m and 4000 m along the P17 section. The mean crustal (super 4) He flux is obtained as 1.0 (+ or -0.4) 10 (super 9) atoms m (super -2) (sub Earth) s (super -1) . Copyright 2001 by the American Geophysical Union.

A total of 173 entanglements was documented. The number of entanglements did not change after implementation of MARPOL Annex V in 1989. Pups and juvenile seals were more likely to become entangled than older seals, and became entangled primarily in nets, whereas entanglement of subadults and adults was more likely to involve line. The subpopulation of seals at Lisianski Island experienced the most entanglements, although Lisianski did not accumulate the most debris. Localized high entanglement rates may gravely affect individual monk seal subpopulations. Accumulation of debris has not diminished since implementation of Annex V, nor has occurrence of derelict drift nets abated since a 1989 moratorium. Debris washing ashore has likely been circulating in the North Pacific Ocean for some time.

An EOF decomposition of intraseasonal outgoing longwave radiation and zonal wind identifies two modes of interannual variability of the MJO: a zonally stationary variation of amplitude that is unrelated to ENSO and a roughly 20 degree -longitude eastward extension of the MJO envelope during El Nino events. The stationary mode is represented by the first two EOFs, which form the familiar lag-correlated quadrature pair, and the eastward-extending mode is represented by the third EOF, which is usually ignored although it is statistically significant. However, the third EOF also has a systematic phase relation with the first pair, and all three should be considered as a triplet; rotating the EOFs makes the phase relation clear. The zonal shift represents about 20% of total MJO variance (which itself is about 55% of intraseasonal variance over the tropical strip). Although the eastward shift is small when compared with the global scale of the MJO, it produces a large proportional shift of MJO activity over the open Pacific, where physical interactions with ENSO processes can occur.

Subsequent tests indicate that swarming patterns were affected by light regime, age and salinity, and that some of the observed patterns may serve to facilitate foraging and respiration. Swarming as such was influenced by density, age and previous feeding, but seemed unaffected by availability of food and salinity. Swimming activity among young Artemia was higher inside swarms than outside, while activity generally decreased as salinity increased. It is further indicated that the horizontal distribution of swarms is affected by salinity and depletion of Artemia over time, while the actual generation of swarms is a result of predisposition as well as chance. It is also demonstrated that young Artemia swarm more readily than older animals and that there is a critical density for immediate swarm formation. The results imply that swarming may reduce the availability of enriched Artemia in larvicultures of fish, and that older Artemia form less coherent swarms than younger Artemia and therefore serve better as live feed.

Behavior was recorded using video cameras with silhouette illumination from infrared-emitting diodes and by visual observation. Laboratory-reared larvae of 1, 3, 8, 10, 12, 18, 22, 27, 42 days post-hatching, ranging in size from 4 mm to 10 mm total length, were used in the experiments. Even the youngest larvae were observed to exhibit a fast startle response. The percentage of successful larval escapes from the different predators increased as the larvae developed. Euphausiids (Thysanoessa raschii) and amphipods (Calliopiella pratti) often touched larvae but the larvae were usually able to escape and no successful captures of larvae over 22 days old were observed. Although successful escape from initial attacks by three-spine sticklebacks (Gasterosteus aculeatus) increased ontogenetically, sticklebacks were able to consume most larvae, even of the oldest age group, by repeated attacks. Day-old larvae had the lowest percent of escapes after encounters with jellyfish (Sarsia sp.), but the percentage of escapes increased dramatically for 3-day-old larvae. Escape speeds after an attack also increased with age, and tended to be higher after stickleback attacks and lower after jellyfish attacks. This study revealed that the escape response of larval pollock to attack by predators improves rapidly with development during the early larval stage.

Based on an analysis of dolphins killed from 1973 to 1990, and depending on the length at which calves are assumed to become independent, there was a deficit of calves relative to the number of lactating females killed in 24%-32% of 1,847 spotted-dolphin sets and in 13%-19% of 563 spinner-dolphin sets. We found a deficit of 0.31-0.45 spotted dolphin and 0.15-0.26 spinner dolphin calves per set. If these missing calves were added to the observed kill, it would represent an increase in the kill of 10%-15% for spotted dolphins and 6%-10% for spinner dolphins in the sets we examined. We did nor attempt to estimate the actual number of unobserved calf deaths due to purse-seine fishing on dolphins, either in the sets we examined or in all dolphin sets. The actual number of unobserved calf deaths is likely to be higher than the calf deficit we found. Separation of dolphin mothers from calves could occur at any of several points in the fishing process, but most of these would be invisible to us and not produce a calf deficit. Estimation of the actual number of unobserved calf deaths would require further information on how frequently permanent mother-calf separations occur, the fraction of calves that survive after separation, the fraction of lactating females set upon that are carrying calves, and the fraction of calves killed that are actually related to lactating females killed in the same set. In any case, the observation of a calf deficit indicates that the reported dolphin kill fails to measure the full impact of purse-seine fishing on spotted and spinner dolphin populations.

During the four hours we watched, adult female killer whales, including some with calves, attacked in waves of four to five animals in what was apparently a "wound and withdraw" strategy. Adult male killer whales stood by until the very end when one charged in and quickly killed a seriously wounded sperm whale that had been separated from the group. The sperm whales appeared largely helpless: their main defensive behavior was the formation of a rosette ("marguerite" - heads together, tails out). When the killer whales were successful in pulling an individual out of the rosette, one or two sperm whales exposed themselves to increased attack by leaving the rosette, flanking the isolated individual, and leading it back into the formation. Despite these efforts, one sperm whale was killed and eaten and the rest were seriously, perhaps mortally, wounded. We also present details of two other encounters between sperm whales and killer whales that we observed. Although sperm whales, because of various behavioral and morphological adaptations, were previously thought to be immune to predation, our observations clearly establish their vulnerability to killer whales. We suggest that killer whale predation has potentially been an important, and underrated, selective factor in the evolution of sperm whale ecology, influencing perhaps the development of their complex social behavior and at-sea distribution patterns.

Doing so requires some appreciation of how episodic events such as from shipping accidents or dredging, and chronic stresses such as contamination from waste disposal, compare with fishing in terms of their impacts on living marine resources. These are all different stresses on individual fish and the issue resolves to extrapolating these stresses to the population level. It is not possible to quantify population effects precisely but it is possible to show that population effects of episodes and of chronic contamination can be compared with the effect of fishing.
