AN - 71146852; 10831091 AB - Polymerizable cyclodextrin derivatives (PCDs) have been proposed as candidates for use in dental therapeutics (Bowen, 1996; Bowen and Reed, 1997). Here, PCD "libraries" were synthesized by quasi-random reactions of 6 moles of methacrylic anhydride plus 6 moles of cyclic glutaric anhydride per mole of beta-cyclodextrin (BCD) in solution. BCD has 21 reactive sites on each of its molecules. These proportions were based on probability calculations, which predicted that the products should have a minimum of 2 polymerizable substituents and acidic ligand groups on practically every one of the diverse product molecules. Matrix-assisted laser desorption/ionization (MALDI) time of flight (TOF) mass spectrometry (MS) gave valuable information regarding the masses of molecular ions representing the molecules that made up the PCD libraries. For the MALDI-TOF MS analyses, small samples were analyzed by the successive application of 3 solutions to the sample holder: the matrix in acetone, the products in water, and sodium trifluoroacetate in water. The resulting spectra had > 40 envelopes of mass peaks above background. The ionic-abundance peak heights had quasi-Gaussian configurations, with central peaks having masses in the neighborhood of 2000 g/mol (Daltons). Regardless of structural permutations within each peak, the range of these peaks was between about 1500 g/mol and 2900 g/mol. This range of masses was in accord with, but perhaps somewhat more narrow than, that predicted by the statistical method, which was based on equal reactivity of all hydroxyl groups. Analysis by MALDI-TOF MS gave valuable data regarding the masses, structures, and characteristics of the products formed and provided unanticipated information to facilitate improvements in future PCD syntheses.

This study focuses on the largely ignored role of the colonial Phaeocystis antarctica in the carbon dioxide cycle. This organism forms large blooms in seasonal ice zones and coastal Antarctic waters. Measurements of dimethylsulphoniopropionate concentrations were used as an indicator of carbon export from surface waters to deep water. In comparison to carbon removal by diatoms, the blooms of Phaeocystis antarctica remove approximately twice the amount of pCO (sub 2) per mole of PO (sub 4) .

The ash is abrasive and capable of causing serious damage to aircraft engines, control surfaces, windshields, and landing lights. In addition, ash can clog the pitot-static systems, which determine wind speed and altitude, and damage sensors used to fly the aircraft. To ensure aviation safety, a warning system should be capable of a 5-min response time once an eruption has been detected. Pilots are the last link in the chain of safety actions to avoid or mitigate encounters with volcanic ash. For the pilots to be effective, the warning and safety system must meet their needs. The ability to issue accurate and timely warnings, advisories, and forecasts requires a rapid means to detect and continually track the ash cloud and smooth coordination between many agencies. The current operational ash detection technique uses satellite remote sensing. Potential problems with this technique and the potential impact of these problems on aircraft safety are discussed.

Phytoplankton biomass in the upper 150 m of the water column ranged from 40 to 540 mg chlorophyll a (Chl a) m (super -2) , exceeding 200 mg Chl a m (super -2) everywhere except the extreme northern and eastern boundaries of the Ross Sea polynya. Diatom biomass was greatest in the shallow mixed layers of Terra Nova Bay, while the more deeply mixed waters of the Ross Sea polynya were dominated by Phaeocystis antarctica. Phytoplankton primary productivity in the Ross Sea averaged 100 g C m (super -2) yr (super -1) during 1996-1997. 70 to 100% of the C and N deficits in the upper 150 m could be accounted for by particulate organic matter, indicating that there had been little dissolved organic matter production or export of particulate material prior to our cruise. This suggests that early in the season, primary productivity and zooplankton grazing are decoupled in the southwestern Ross Sea. The nitrate:phosphate disappearance ratio in waters dominated by P. antarctica (19.0+ or -0.61) was significantly greater than in waters where diatoms were most common (9.52+ or -0.33), and both were significantly different from the Redfield N:P ratio of 16. Vertical profiles suggest that P. antarctica took up 110% more CO (sub 2) per mole of PO (sub 4) removed than did diatoms, an important consideration for climate models that estimate C uptake from the removal of PO (sub 4) .

Inversion of computed response functions is carried out using a minimum structure, regularized approach. The upper mantle beneath Carty Lake is approximately an order of magnitude more resistive than the upper mantle beneath Tucson and nearly 1.5 orders of magnitude more resistive than Honolulu and Midway Island. Inversions were also carried out where the minimum structure constraint was removed at known upper mantle discontinuities. These models show a jump in conductivity of approximately 1.5 orders of magnitude across the 660 km discontinuity, a result that is consistent with laboratory experiments on realistic mantle assemblages. Mantle conductivity profiles at Carty Lake are significantly more resistive than those at Tucson, Honolulu, and Midway to depths of approximately 300-400 km. These observations likely reflect differing thermal states, the presence (or absence) of partial melt and volatiles, and may also be related to chemical differences between depleted and undepleted upper mantle. The observed conductivity variations may be interpreted as lateral variations in temperature, partial melt, and/or dissolved hydrogen in olivine. Copyright 2000 by the American Geophysical Union.

The method is based on combined vertical modes of temperature T and salinity S and reconstructs salinity profiles via a weighted least squares procedure. The major advantages of this new approach over using a climatological T-S relationship are that seasonal-to-interannual variability is better taken into account and that the method combines in a consistent way different sources of information such as T and S profiles and sea surface height. The present results estimate the salinity along 165 degrees E in the western Pacific Ocean for the 1993-1998 period and emphasize the importance of the salinity on sea level variability. The reverse problem of estimating the salinity variability along the water column from the satellite-derived sea level and sea surface fields is also investigated. Finally, comparison with in situ salinity observations demonstrates the possibility of extracting useful information about the salinity variability from the TOPEX/Poseidon altimeter data.

The computed flow fields show that flow in porous media is restricted to preferential paths depending on the size and connectivity of pores. Whole areas of the pore structure are relatively isolated from the flow because of bottlenecks. The distribution of the isolated regions depends on the angularity of the grains and the porosity of the medium. The more angular the grains are the greater is the possibility for the presence of isolated regions. For grains with the same angularity a decrease in the porosity leads to concentration of flow along preferential flow paths. The permeability tensor coefficients are derived from the flow fields of the two-dimensional images as well as the three-dimensional computer-simulated images of soil microstructure. The numerical values of permeability and permeability anisotropy ratio compare well with laboratory experimental data. Copyright 2000 by the American Geophysical Union.

Dalton Jumbo Rototags registered were applied to each hind flipper of 5,743 recently weaned elephant seal pups on Marion Island from 1983 to 1993. We adapted and developed a method based on the resighting times of seals retaining 1 or 2 tags to estimate tag loss and test for effects of age and sex of the seals. Tag loss by young seals was low, but there was a strong increase in tag loss with seal age, especially for males. Annual single tag loss at age 14 was 10% for males and 5.6% for females. Although these are relatively modest rates of tag loss, substantial fractions of seals (35% of males and 17% of females) would lose both tags by age 15, requiring corrections to avoid bias in demographic studies based on these tagging data. The method we used to estimate tag loss has significant advantages over a ratio estimator that has been used for most previous studies of tag loss in pinnipeds.

The objectives of my study were to determine partitioning of habitat among age groups of rainbow trout, Oncorhynchus mykiss, coexisting in pool habitat of a headwater stream, and to determine the role of intraspecific competition for such resource partitioning. The trout population showed size and age specific patterns of habitat use, and trout selected locations based on depth and longitudinal position. This habitat use pattern decreased intraspecific overlap among the trout age groups for use of pool space. I used a removal experiment to determine if two-year old trout constrained habitat use by the smaller conspecifics. Although the experimental results imply that recent intraspecific competition was not present, the absence of competitive exclusion was not clearly demonstrated because of low experimental power. While this study identified habitat partitioning among the trout age groups, it remains unclear whether biotic interactions or size specific requirements were causing the habitat use patterns.

Black and white aerial photographs (1:24,000 scale) of four representative sites where S. alterniflora has invaded were analyzed. Individual patches were digitized on a computer, and diameter and area were computed for each patch for all years and sites sampled using CAD software. Lateral growth rates of individual S. alterniflora patches increased linearly at 79.3 ( plus or minus 1.674 SE) cm yr super(-1). Back calculations of origin dates for individual patches based on mean lateral growth rates indicate that recruitment of new patches has been episodic and increasing in frequency since initial introduction.

The method of analysis, which focused on a prototype three-element link-mount design, can be extended to arbitrary multiple-element link mounts, including single-element simply supported links. A method was developed to determine the values of the set of parameters that characterize a particular multiple link-mount design. This involves: (1) the measured time-dependent thermal response of the link-mount design to exposure in a plunge test, the type of test used to characterize the thermal response of sprinkler links; and (2) an analytic means of determining values of the design parameters that yield an optimum fit between a solution to the model equations and the temperature data. The method takes account of the pre-fusing solder-melting phase of fusible-link response. The latter was shown to be very important for the link design used in this study. The method was carried out successfully for four plunge tests involving three link-mount systems and one or two system/flow orientations. The resulting system parameters and model equations were used in a successful simulation of vent actuation in a real, large-scale, fire scenario.

At the atoll of French Frigate Shoals, recent evidence of emaciation and low survival in monk seals prompted a search for their specific prey communities and foraging habitat. A video camera (National Geographic Television's CRITTERCAM) fitted to 24 adult male seals documented benthic and demersal foraging on the deep slopes (50-80 m) of the atoll and neighboring banks. The number of bottom searches for prey was compared by year, time of day, type of bottom, individual seal, and length of bottom time. Analysis of variance identified a significant interaction of seal and bottom type, explaining 65% of the total variance. Seals fed on communities of cryptic fauna (fish and large invertebrates) in transitional "ecotone" regions of low relief where consolidated substrate, rubble, and talus bordered areas of sand. Independent areal surveys of bottom types throughout the atoll and neighboring banks suggest that the type of bottom selected as foraging habitat represents a relatively small percentage of the total benthic area available.

Herein we use the economic theory of endogenous risk to address this optimal mix of mitigation and adaptation strategies, and examine how increased variability in climate change threats affects this mix. We stress that a better understanding of the cross-links between mitigation and adaptation would potentially make it possible to provide more risk reduction with less wealth. Policies that are formulated without considering the cross-links can unintentionally undermine the effectiveness of public sector policies and programs because of unaddressed conflicts between the strategies. We also discuss the cross-disciplinary lessons to be learned from this literature, and identify important research questions to spur discussion in the next round of inquiry.

Catch per unit effort of large coastal sharks declined rapidly during the 1970s and 1980s. Measures were imposed to prevent overfishing, but fishing mortality rates have not declined as much as expected, and stocks have not improved, so further conservation measures are needed. Several management options, including nursery ground closures and size limits, are being considered. The implications for such options are examined using a life cycle stage-based model. At the current fishing mortality rate, the model projects a population decline to 13% of its current abundance in 20 yr. Populations do not stabilize until the fishing mortality rate is reduced to 0.07. Even with nursery closure or size limits, this rate has to be reduced substantially. The model is very sensitive to the dynamics of juveniles and subadults, suggesting that these stages should be protected to rebuild the stock.

The heat content of the world ocean increased by similar to 2 x 10 super(23) joules between the mid-1950s and mid-1990s, representing a volume mean warming of 0.06 degree C. This corresponds to a warming rate of 0.3 watt per meter squared (per unit area of Earth's surface). Substantial changes in heat content occurred in the 300- to 1000-meter layers of each ocean and in depths greater than 1000 meters of the North Atlantic. The global volume mean temperature increase for the 0- to 300-meter layer was 0.31 degree C, corresponding to an increase in heat content for this layer of similar to 10 super(23) joules between the mid-1950 and mid-1990s. The Atlantic and Pacific Oceans have undergone a net warming since the 1950s and the Indian Ocean has warmed since the mid-1960s, although the warming is not monotonic.

Previous explanations for this observation have typically had difficulty accounting for either the estimated glacial O sub(2) concentrations in the deep sea, super(13)C/ super(12)C ratios in Antarctic surface waters, or the depth of calcite saturation; also lacking is an explanation for the strong link between atmospheric CO sub(2) and Antarctic air temperature. There is growing evidence that the amount of deep water upwellng at low latitudes is significantly overestimated in most ocean general circulation models and simpler box models perviously used to investigate this problem. Here we use a box model with deep-water upwelling confined to south of 55 degree S to investigate the glacial-interglacial linkages between Antarctic air temperature and atmospheric CO sub(2) variations. We suggest that low glacial atmospheric CO sub(2) levels might result from reduced deep-water ventilation associated with either year-round Antarctic sea-ice coverage, or wintertime coverage combined with ice-induced stratification during the summer. The model presented here reproduces 67 parts per million of the observed glacial-interglacial CO sub(2) difference, as a result of reduced air-sea gas exchange in the Antarctic region, and is generally consistent with the additional observational constraints.

Loggerheads have been found in nearshore waters off China, Taiwan, Japan, Australia, and New Zealand in the Western Pacific and are seen offshore of Washington and California State and Baja California, Mexico in the Eastern Pacific (Dodd, 1988). Nesting areas in the Pacific Ocean are mainly on the western side, Japan and Australia, with no known nesting in the Eastern Pacific. Mean growth rates for juvenile loggerheads in the North Pacific have been estimated at 4.2 cm/year (Zug et ah, 1995). Loggerheads have an extended pelagic stage, which can last until sexual maturity. Transpacific migrations of juvenile loggerheads have been documented from mitochondrial DNA testing of loggerheads found feeding off of California and Baja identifying these turtles as being from Japan and Australia (Bowen et ah, 1995). Recent pelagic satellite tracking of juvenile, sub-adult, and adult size loggerheads indicate that they are active in their migration, swimming against weak geostrophic currents and following subtropical fronts as they travel from east to west across the Pacific (Polovina et al., 2000).

The STSSN relies on a group of trained volunteers, including state and federal employees and private individuals, to collect basic biological data on each turtle located. Each animal is identified to species, the condition or state of decomposition is determined, standard carapace measurements are taken, and any obvious wounds, injuries, or abnormalities are noted and described. Volunteers who have received additional training may also perform necropsies, or internal exams, on a carcass to determine the general state of health of the animal prior to death, determine sex, and locate any obvious internal abnormalities. Data are recorded on standardized report forms which are submitted first to a state coordinator and then to the national STSSN coordinator at the National Marine Fisheries Service, Southeast Fisheries Science Center, Miami, Florida.

However, as sea turtles cannot be aged based on external characteristics, it is only possible to estimate the age at maturity using indirect methods such as measuring the growth rates of wild, recaptured turtles. Previous studies have documented a higher rate of growth for wild, juvenile loggerhead (Caretta caretta) sea turtles in the southern Bahamas and Florida than in Virginia. The National Marine Fisheries Service sea turtle program in Beaufort, North Carolina has been conducting mark-recapture studies in Core and Pamlico Sounds, North Carolina since 1988, and has tagged a total of 978 loggerhead sea turtles, most of which were incidentally captured in commercial pound nets. Data from the New York State Marine Turtle Project were also included in the analysis. Straight-line measurements of carapace length (notch-tip) taken for each turtle ranged from 41.4-103.0 cm. External Inconel Style 681 tags applied to both rear flippers and internal passive integrated transponder (PIT) tags injected into the left front flipper enabled identification of recaptured turtles. Growth rates (carapace length initial-carapace length at recapture/years at large) were assigned to a 10 cm size class based on the mean of the initial and recapture length and averaged. Multiple t-tests were used to calculate differences in mean growth rates among the recaptured loggerheads from the different regions of the western Atlantic. To date, 29 loggerheads have been recaptured after being at large for 11 months or more, allowing for measurable growth. Similar to Virginia, North Carolina and New York had slower growth rates compared to Florida and the Bahamas although these differences were not always significant. Differences in growth rate have been attributed to the seasonal availability of food as well as the costs associated with seasonal migrations. Growth rates may also vary depending upon the genetic composition of the respective populations. This may have important ramifications for the management of the declining northern nesting population of loggerhead sea turtles.

Morphometric data, including carapace length, carapace width and body depth were collected on live or fresh dead turtles and regression analyses were performed to develop predictive regression equations for carapace width (when not actually measured) and body depth of stranded turtles. Loggerhead and green turtle standings with carapace widths greater than the currently required minimum TED width openings have not exceeded 1-2% of the total measured standings in any year since 1986. Loggerhead turtle standings with body depths greater than the currently required minimum TED height opening have ranged between 33-47% of the total measured standings since 1986. Green turtle standings with body depths greater than the currently required minimum TED height opening have ranged from 1-7% of total measured standings since 1986. None of the Kemp's ridley standings measured between 1986 and 1997 had carapace widths or body depths greater than the currently required minimum TED openings. In order to reduce trawl mortality of large turtles, the TED opening dimensions need to be increased in both the Gulf of Mexico and southeast U.S. Atlantic.

During August 1998 to April 1999, the project pumped 8.3 million yd super(3) of sand from offshore borrow sites onto 17.5 mi of gulf beach. Panama City Beach supports a small but important nesting population of loggerhead turtles. Nourishment can alter beach characteristics in a way that decreases the reproductive success of sea turtles. We compared data for nest placement, nesting success (nests divided by total crawls), hatchling production, and incubation periods obtained prior to the nourishment project (1991-98) with post-nourishment data for the 1999 nesting season. Results showed that the nesting turtles did not utilize the wider, nourished beach. Instead, all nests were laid close to the water near an escarpment that formed along the shoreline. Nesting success dropped slightly but was within the normal variation for this beach, and hatchling production was well above normal. The average nest incubation period of 60 days was 10 days shorter than the eight year average for the pre-nourished beach. Multiple-variable regression analysis of the 1999 data showed a strong correlation between incubation period, air temperature, and sand luminance at the nest sites. The darker sands of the nourished beach likely contributed to the shorter incubation times, but the analysis showed that additional factors are involved.

These activities often carry with them the desire to communicate to others what we have been fortunate to see and learn about these amazing animals. However, there are practical limits to the amount of time that can be spent in the field. Also, the potential influence of our direct presence on the turtles is always a consideration. In order to expand our field of vision over the horizon, using new viewing technologies, the world's first camera system with real-time video linkage to the Internet is being implemented to watch turtles in the Hawaiian Islands.

Consequently, the current status of immature sea turtles in southwest Florida is unknown, particularly the highly endangered Kemp's ridley turtle. The purpose of this project is to determine the relative abundance, temporal and spatial distributions, movements, growth, and habitat requirements of immature sea turtles in the nearshore waters of southwest Florida. Our research efforts focus on the highly endangered Kemp's ridley turtle, but other turtle species are also collected during routine sampling operations.

PIT tagging and photo-identification have enabled us to identify potential new recruits and long-term remigrants and compile their reproductive histories. This nesting population has grown significantly in the last six years, and theoretically the new 'recruits' may be the offspring of the older remigrants. Pairwise relatedness (R) was calculated across all nine loci among the 172 female leatherbacks analyzed to date using methods described in Queller and Goodnight (1989), and UPGMA trees constructed to visualize potential family groupings. First-order relations (R greater than or equal to 0.5) were common and groupings based on microsatellite data were consistent with mtDNA haplotype data, suggesting that individuals were related maternally, either as mother-daughter, or sisters. By examining reproductive histories and allele distributions it was possible to identify the mother of a group of siblings that came from the same clutch, or clutches produced during the same season. This approach provides direct evidence for natal homing in leatherbacks. Further analysis will be carried out to identify mother-daughter relations. By examining reproductive histories of mothers and their daughters, it should be possible to gain insights into age of maturity for this species.

Analyses of thevertical soil profiles indicate that super(137)Cs ispresent in the upper 5-20 cm of the soil. Crops andthe majority of wild plants show no signs ofcontamination with super(137)Cs even in areas where soilis contaminated. A regional map of super(137)Csconcentration is presented, which shows a highlyirregular pattern of radio-cesium deposition from thenuclear tests on the Semipalatinsk Nuclear Polygonbetween 1949 to 1962. This kind of lateraldistribution of super(137)Cs in Altay virgin topsoilscannot be accounted for only by the distance from thenuclear testing site, on the contrary, it seems to bepredominantly dependent on the weather conditions anda pattern of rainfall at the time of Semipalatinskexplosions. The article discusses the factors causingthe post-precipitation redistribution of super(137)Cs inthe soil column and demonstrates that forest litter,lichen and lake bottom sediments can be used assensitive indicators of the historical and currentradioactive contamination.

AN - 70950059; 10698729 AB - Certain marine algae produce potent toxins that impact human health through the consumption of contaminated shellfish and finfish and through water or aerosol exposure. Over the past three decades, the frequency and global distribution of toxic algal incidents appear to have increased, and human intoxications from novel algal sources have occurred. This increase is of particular concern, since it parallels recent evidence of large-scale ecologic disturbances that coincide with trends in global warming. The extent to which human activities have contributed to their increase therefore comes into question. This review summarizes the origins and health effects of marine algal toxins, as well as changes in their current global distribution, and examines possible causes for the recent increase in their occurrence.

However, its duration was remarkable remaining off the northern Outer Banks for nearly a week generating large waves that impacted the coast. In fact at the US Army Corps of Engineers Research Pier at Duck, wave height was the third highest in the over 20 years of record reaching 6.3 m at a buoy in 20 m of water. Measurements of sea level, including astronomical tides and storm surge, were also near record levels. Preliminary calculations of the elevation of wave runup on the beach (that is, the highest reach of the waves) was among the highest on record. To measure the amount of coastal change, USGS and its partners at NASA and NOAA conducted an airborne laser altimetry survey of the impacted areas, from near the VA-NC line to south of Cape Hatteras at Ocracoke Inlet using NASA's Airborne Topographic Mapper (ATM) These data are being compared to a pre-storm survey of the same area acquired in 1998. Initial analyses show that erosion of dunes between Cape Hatteras and Oregon Inlet was highly variable along the coast. In some areas, dunes retreated greater than 30 m whereas in other areas the dunes were stable. At some of the erosional "hot" spots, overtopping and overwash occurred seriously impacting the coastal highway. A "hot" spot at Rodanthe lead to the loss of several ocean front houses clearly revealed in the laser altimetry data. This spatial variability of "hot" and "cold" spots, which repeated along the coast over scales of kilometers, may be related to varying nearshore geology.

The barrier straddles the New River submarine headland and separates sand rich regressive barriers to the northeast from the low sand volume transgressive islands to the southwest. Browns and New River Inlets located at the barrier's northern and southern ends respectively are characterized by contrasting behavior patterns that have controlled the island's morphology and shoreline change patterns. The relative stability of Brown's Inlet has resulted in the formation of a 2 km long, forested dune ridge complex along the northern portion of the barrier. Unstable New River Inlet is a southwesterly migrating, modified system that has migrated 350 m to the south since 1950. During this time average erosion rates have increased from 0.35 m/y to more than 2.5 m/y along the southern portion of the island. Short-term erosion rates are as high as 12 m/y. Since 1963, more than 270 m of recession has occurred along the overwash prone southern 3 km of the barrier. The majority of the shoreface fronting the barrier from south of New River Inlet north to Brown's Inlet is composed primarily of the upper Oligocene Belgrade Formation, a sandy moldic biosparrudite that forms the submarine headland. A transition in shoreface morphology and sediment availability is coincident with the transition from regressive to transgressive barriers, and the contact between the Belgrade Fm and the sand-rich lower Miocene (?) Silverdale Fm in the vicinity of Brown's Inlet. The lack of sediment along much of the shoreface coupled with the migratory behavior of New River Inlet has been responsible for the rapid translation of the southern portion of the barrier.

Axial Seamount is the focus of the New Millennium Observatory (NeMO) project, an extensive campaign to study the seamount starting in 1998. Basaltic glass samples were collected around the seamount by the remotely operated submersible ROPOS (70 samples) and using a ship-mounted wax corer (110 samples). Major and trace element data for the glass samples have been collected and this information has been analyzed using GIS techniques to characterize spatial trends in geochemistry in the caldera region and the rift zones associated with the seamount, as well as neighboring segments of the Juan de Fuca ridge. Combined with morphologic and tectonic information from SeaBeam high resolution sonar mapping and bathymetry, the geochemical data in the GIS has been used to identify patterns associated with magma fractionation and migration of volcanism with time, and to aid in the identification of potential different magma sources in the rift zones. The rift zones are composed of parallel-trending sets of topographic ridges that appear to be dike-fed volcanic constructs that emanate from the flanks of Axial seamount. Slope analyses using digital elevation models of theses rift zones reveal an increasing attenuation of topography due to increased sedimentation and mass wasting toward the west, corroborating other evidence of migration of volcanism to the east. GIS tools have proven invaluable in the storage and manipulation of the voluminous spatial data collected in this study, and have aided in the extraction of information used to identify the magmatic and tectonic mechanisms that operate in the Axial Seamount region.

Observations of the downwelling atmospheric radiation as a function of angle were used to achieve a highly accurate absolute calibration. The dependence of the sea surface brightness temperature on nadir and azimuthal angles is considered. The experimental data are compared with theoretical calculations based on several models of sea wave spectra. Models proposed by Romeiser et al. [1997] and Elfouhaily et al. [1997] fit well to the COPE azimuthal measurements and data averaged over azimuthal angle are in between of values predicted by spectrum models by Apel [1994] and Elfouhaily et al. [1997]. The conclusion is made about high sensitivity of the polarized radiometric measurements to parameters of gravity-capillary spectrum. Copyright 2000 by the American Geophysical Union.

This problem has been studied in detail for 105-115 pelagic longline vessels home-ported in Hawaii, which kill between 1000-2000 each of both Black-footed and Laysan Albatrosses each year. No takes of Short-tailed Albatrosses have been reported for the Hawaii longline fishery, but between 1987 and 1999 a total of six birds has been reported incidentally caught in the Alaska longline fisheries. The Black-footed and Laysan Albatrosses are most vulnerable to longline fishing for Broadbill Swordfish Xiphias gladius, where longlines are set near the surface providing ample opportunity for albatrosses to intercept baited hooks. Studies of the rarer Black-footed Albatross population revealed fishery-induced mortality to be a chronic rather than a catastrophic source of mortality. Some simple mitigation methods implemented in the fishery should reduce the incidental catch of albatross by an order of magnitude and eventually lead to negligible take levels. However, the Hawaii-based longline vessels targeting swordfish represent only a small fraction of pelagic longline effort in the North Pacific and albatrosses will continue to be taken by Japanese, Taiwanese and Korean longliners operating in the same vicinity. Asian longline vessels fish primarily for tuna Thunnus spp. and are likely to have much lower albatross take rates than the Hawaii-based fleet, but collectively these 3000+ vessels still represent a significant threat to North Pacific albatrosses. Although several multilateral fishery bodies and agreements identify cost-effective methods to reduce significantly the incidental catch of seabirds in longline fisheries, very few international or national fishery management organizations require longline fishers to employ these mitigation measures. There is a need to strengthen international efforts to reduce seabird mortality on longlines, and effective monitoring of albatross populations in the North Pacific to gauge the success of mitigation measures.

Some simple mitigation methods implemented in the fishery should reduce the incidental catch of albatross by an order of magnitude and eventually lead to negligible take levels. However, the Hawaii-based longline vessels targeting swordfish represent only a small fraction of pelagic longline effort in the North Pacific and albatrosses will continue to be taken by Japanese, Taiwanese and Korean longliners operating in the same vicinity. These Asian vessels fish primarily for tuna Thunnus spp. and are likely to have much lower albatross take rates than the Hawaii-based fleet, but collectively these 3000+ vessels still represent a significant threat to North Pacific albatrosses. Although several multilateral agreements identify cost-effective methods to reduce significantly the incidental catch of seabirds in longline fisheries, very few international or national fishery management organizations require longline fishers to employ these mitigation measures. There is a need to strengthen international efforts to reduce seabird mortality on longlines, and for effective monitoring of albatross populations to gauge the success of mitigation measures.

Using a published correction factor, we estimated the total non-pup population size in Alaska of the western stock of Steller sea lions to be about 33,000 animals. Based on a published life table and the current rate of decline, we estimate that the total number of mortalities of non-pup Steller sea lions during 1991-2000 was about 6,383 animals; of those, 4,718 (74%) are mortalities that would have occurred if the population were stable, and 1,666 (26%) are additional mortalities that fueled the decline. We tabulated the levels of reported anthropogenic sources of mortality (subsistence, incidental take in fisheries, and research), estimated another (illegal shooting), then approximated levels of predation (killer whales and sharks). We attempted to partition the various sources of "additional" mortalities as anthropogenic and as additional mortality including some predation. We classified 436 anthropogenic mortalities and 769 anthropogenic plus some predation mortalities as "mortality above replacement"; this accounted for 26% and 46% of the estimated total level of "mortality above replacement", respectively. The remaining mortality (74% and 54%, respectively) was not attributed to a specific cause and may be the result of nutritional stress.

This habitat consists of a variety of hard-surface, elevated relief "reef" or reef-like environments that are widely distributed across the predominantly flat or undulating, sandy areas of the Bight and include both natural rocky areas and man-made structures, e.g. shipwrecks and artificial reefs. Although there are natural rock and shellfish reefs in southern New England coastal waters and estuaries throughout the Bight, most reef habitats in the region appear to be man-made, mostly wrecks and "obstructions," and man-made reef habitat modification/creation may be increasing. Very little effort has been devoted to the study of this habitat's distribution, abundance, use by living marine resources and associated biological communities (except on estuarine oyster reefs), and fishery value or management. This poorly studied and surveyed habitat can provide fish refuge from trawls and can be a factor in studies of the distribution and abundance of a variety of reef-associated fishery resources. This review provides a preliminary summary of information found on relative distribution and abundance of reef habitat in the Bight, the living marine resources and biological communities that commonly use it, threats to this habitat and its biological resources, and the value or potential value of artificial reefs to fishery or habitat managers. The purpose of the review is to initiate an awareness among resource managers about this habitat, its role in resource management, and the need for research.

The voluntary IPOA-Seabirds applies to States with longline fisheries and would be implemented through the development of National Plans of Action, no later than early 2001. The US NPOA-Seabirds contains the following themes: 1) Regional assessments of seabird interactions with longline fisheries; 2) If a problem exists, then actions should be taken - data collection; prescription of mitigation measures; research and development; and outreach about seabird bycatch; 3) Annual regional reports on the status of NPOA-Seabirds implementation; 4) Cooperative efforts between NMFS and FWS on seabird bycatch issues and research; and 5) A national commitment to advocate the development of National Plans of Action within international fora. By working cooperatively, fishermen, managers, regional fishery management councils, scientists, and the public will use this national framework to achieve a balanced solution to the seabird bycatch problem, promoting continuing sustainability of our national marine resources.

Using WSR-88D radar imagery, 16 well-defined and 18 marginal lake-effect events were identified from September 1994 through May 1998 (excluding June-August), with the former used for more detailed analysis. Precipitation during the well-defined events was frequently characterized by the irregular development of radar echoes over and downstream of the Great Salt Lake. The most commonly observed precipitation structures were solitary wind-parallel bands that developed along or near the major axis of the GSL and broad-area precipitation shields with embedded convective elements that formed near the southern shoreline. Regional-scale composite analyses and rawinsonde-derived statistics showed that the lake-effect events occurred in post frontal westerly to northerly 700-hPa flow following the passage of an upper-level trough and associated low-level cold front. The lake-effect environment was characterized by limited steering layer (800-600 hPa) directional shear (generally 60 degree or less), moist- to dry-adiabatic low-level lapse rates, and small convective available potential energy (CAPE), although the CAPE may be locally greater over the Great Salt Lake. In all events, the lake-700-hPa temperature difference exceeded 16 degree C, which roughly corresponds to a dry-adiabatic lapse rate. The lake-land temperature difference was always positive and usually exceeded 6 degree C, indicating significant potential for the development of land-breeze circulations and associated low-level convergence over the lake. Radar-derived statistics suggest that lake enhancement is strongest during periods of northwesterly to northerly flow and large lake-land temperature differences. These characteristics are compared with those associated with lake-effect snowstorms of the Great Lakes and implications for operational forecasting are discussed.

The results from a three-dimensional circulation model and a wind wave model were used as input to the sediment transport model. Two effects of nonlinear wave-current interactions were considered in the sediment transport model: the changes in turbulence intensity due to waves and the enhancement of induced bottom shear stresses. Empirical formulations of sediment entrainment and resuspension processes were established and parameterized by laboratory data and field studies in the lake. In this preliminary application of the model to Lake Michigan, only a single grain size is used to characterize the sedimentary material, and the bottom of the lake is treated as an unlimited sediment source. The model results were compared with measured suspended sediment concentrations at two stations and several municipal water intake turbidity measurements in southern Lake Michigan during November-December 1994. The model was able to reproduce the general patterns of high-turbidity events in the lake. A model simulation for the entire 1994-1995 two-year period gave a reasonable description of sediment erosion/deposition in the lake, and the modeled settling mass fluxes were consistent with sediment trap data. The mechanisms of sediment resuspension and transport in southern Lake Michigan are discussed. To improve the model, sediment classifications, spatial bottom sediment distribution, sediment source function, and tributary sediment discharge should be considered.

SAR has an advantage over many sensors because it can pass through clouds and take images at any time of day. However, since SAR's detection capability is based on the modulation of the sea surface wind field, it can only observe storms over water. Hurricanes and other mesoscale storms are easily detected with existing observations, but SAR can contribute fine-resolution low-level information that cannot be seen below the cloud deck with other sensors. Using Radarsat-1, we have imaged three hurricanes during the 1998 season. Two SAR images of Hurricane Bonnie separated by 1 day are presented, and observations from the SAR data are discussed.

The historical development of stock identification methods has paralleled the advancement of morphometric techniques. The earliest analyses of morphometric variables for stock identification were univariate comparisons, but were soon followed by bivariate analyses of relative growth to detect ontogenetic changes and geographic variation among fish stocks. As the field of multivariate morphometrics flourished, a suite of multivariate methods was applied to quantify variation in growth and form among stocks. More recent advances have been facilitated by image processing techniques, more comprehensive and precise data collection, more efficient quantification of shape, and new analytical tools. Many benchmark case studies and critiques offer guidelines for sampling morphometrics and interpreting multivariate analyses for exploratory stock identification, stock discrimination, and stock delineation. As examples of morphometric stock identification based on life history differences, allometric patterns of crustacean secondary sex characters have been used to detect geographic variation in size at maturity, and morphometric correlates to smoltification have been used to discriminate salmon from different rivers. Morphometric analysis provides a powerful complement to genetic and environmental stock identification approaches. The challenge for the future of morphometric stock identification is to develop a consensus on biological interpretations of geometric analyses, similar to the conventional interpretations of size and shape from traditional multivariate morphometrics.

These fronts are characterized by gradients in sea surface height that produce an eastward geostrophic current, with gradients in surface chlorophyll and SST. Six of the turtles were associated with a front characterized by 17 degree C SST, surface chlorophyll of about 0.2 mg m super(-3), and eastward geostrophic current of about 4 cm s super(-1), while the other three turtles were associated with a front with 20 degree C SST, surface chlorophyll of about 0.1 mg m super(-3), and eastward geostrophic flow of about 7 cm s super(-1). These results appear to explain why incidental catch rates of loggerheads in the Hawaii longline fishery are highest when gear is set at 17 degree C and 20 degree C, SST. Further, from the seasonal distribution of longline effort relative to these fronts, it appears that the surface longline fishing ground lies largely between these two fronts during the first quarter and well to the south of the 17 degree C front, but including the 20 degree C front, in the second quarter. These findings suggest seasonal or area closures of the longline fishery that could be tested to reduce incidental catches of loggerheads. Finally, these results illustrate the insights which can be achieved by combining data on movement of pelagic animals with concurrent remotely sensed environmental data.

We describe the strengths and weaknesses of a suite of approaches that assess the scope and magnitude of fishery and predatory mortality in aquatic ecosystems. We examine: (i) empirical models for pattern detection, process exploration, and model parameterization (e.g. multispecies time series and multiple regression); (ii) qualitative process-based models of species interactions (e.g. food web analyses and loop analyses); and quantitative process-based multispecies models that include: (iii) static flow models (e.g. ECOPATH); (iv) dynamic models of either numerical abundance (e.g. Lotka-Volterra) or biomass (e.g, ECOSIM and multispecies biomass dynamics); and (v) spatially explicit versions of the above. Decisions concerning a specific modelling approach should be evaluated in the context of the goals of the model and empirical database. Important considerations include model use, desired output, and management context. Four important factors to consider in model selection are the spatial and temporal extent and resolution, conservation of mass or numbers, mathematical representation of predator-prey interactions, and mathematical representation of technical interactions. We conclude that the most effective modelling exercise to achieve a given set of goals should incorporate the evaluation of multiple model configurations.

A variety of environmental chemicals are also active at sex steroid receptors and theoretically possess the potential to alter normal sexual differentiation in fish. However, in controlled environmental chemical exposures to date, only partial alterations of fish sexual phenotype have been observed. Here we report complete, permanent, and functional male-to-female sex reversal in the Japanese medaka (Oryzias latipes, d-rR strain) after a onetime embryonic exposure to the xenoestrogen o,p'-DDT. d-rR strain medaka are strict gonochorists that possesses both sex-linked pigmentation, which distinguishes genotypic sex, and sexually dimorphic external secondary sexual characteristics, which distinguish phenotypic sex. We directly microinjected the xenoestrogen o,p'-DDT into the egg yolks of medaka at fertilization to parallel the maternal transfer of lipophilic contaminants to the embryo. At 10 weeks of age, microinjected medaka were examined for mortality and sex reversal. A calculated embryonic dose of 511 plus or minus 22 ng/egg o,p'-DDT (mean plus or minus standard error) resulted in 50% mortality. An embryonic exposure of 227 plus or minus 22 ng/egg o,p'-DDT resulted in 86% (6 of 7) sex reversal of genetic males to a female phenotype (XY females). XY females were distinguished by sex-linked male pigmentation accompanying female secondary sexual characteristics. Histologic examination of the gonads confirmed active ovaries in 100% of the XY females. In 10-day breeding trials in which XY females were paired with normal XY males, 50% of the XY females produced fertilized embryos; this represents a comparable breeding success rate to normal XX females. Fertilized eggs produced from XY females hatched to viable larvae. These results clearly indicate that a weakly estrogenic pesticide, o,p'-DDT, when presented during the critical period of gonadal development, can profoundly alter sexual differentiation.

I show that mean monthly catch per unit effort of groupers and snappers declined with increasing fishing intensity during the study period, suggesting overfishing. Mean monthly yields of other less desirable stocks remained constant but were never more than 3% of the total demersal yield. Mean yields of all fishes except snappers were higher on the east coast than on the west coast and were higher for all fishes during July to November than December to June. Tourism and the Island's population increased during the same period, were inversely correlated with annual yields of demersal fishes, and may have driven fishery harvest. Although demersal reef fishes comprised only 7% of Grenada's fishery harvest, they are important sources of food and income to local fishers. Declining demersal catches may not be critical at present, but the absence of groupers and large snappers from coral reefs in more economically developed islands (e.g., Barbados, Bermuda, and U.S. Virgin Islands) suggests that the fate of Grenada's demersal fisheries may be similar if observed trends continue. Regulations are necessary to sustain Grenada's demersal fisheries.

Embryos were exposed for 24 h to either chlorpyrifos or malathion. All exposure concentrations were nominal and ranged from 0 to 2.00 mu g l super(-1) for chlorpyrifos and from 0 to 120.00 mu g l super(-1) for malathion. Quantifiable levels of AChE activity first appeared at Stage V of development and increased as embryonic development progressed. AChE inhibition by the OPs was assessed in Stage VI and Stage VII embryos. Both stages of embryos were more sensitive to chlorpyrifos than malathion. The 24-h Effective Concentration (EC sub(50)) values for chlorpyrifos were 0.49 mu g l super(-1) (95% C.I.=0.33-0.77 mu g l super(-1)) and 0.36 mu g l super(-1) (95% C.I.=0.33-0.38 mu g l super(-1)) for Stage VI and Stage VII embryos, respectively. In comparison, malathion 24-h EC sub(50) values were 55.53 mu g l super(-1) (95% C.I.=22.08-80.73 mu g l super(-1)) for Stage VI embryos and 29.93 mu g l super(-1) (95% C.I.=25.22-44.22 mu g l super(-1)) for Stage VII embryos. For both OPs, there were no significant differences in the EC sub(50) values calculated for Stage VI and Stage VII embryos; however, AChE inhibition was significantly (P less than or equal to 0.05) greater in Stage VII embryos at the two highest exposure concentrations for each insecticide. A comparison of the results of these embryo tests with those found for adult and larval toxicity tests indicated that embryos were at least as sensitive to both the OPs as larval and adult grass shrimp. Embryo bioassays provide a number of important advantages over traditional laboratory toxicity tests including reduced laboratory space requirements, large numbers of embryos from a few ovigerous females, and small volumes of waste.

Distinguishing among these signatures objectively can be very difficult, especially with only the single-band and single-polarization SAR imagery available from the European Remote Sensing satellites and the Canadian Radarsat-1. Nevertheless, distinctive patterns, when interpreted in the context of the geographic region, season, and local weather conditions, can be extremely useful in properly identifying many of the observed low-backscatter features. Examples of such features presented here are interpreted based on the regional and temporal context of the SAR imagery as well as the morphology and temporal persistence of the features.

During the last few years, products available through CoastWatch have expanded beyond the original infrared, visible, and sea surface temperature images to include ocean color, scatterometer wind, and synthetic aperture radar (SAR) images. A NOAA research and development program with partners in government, academia, and industry has endeavored to develop coastal ocean SAR applications for CoastWatch. Some of these applications, in particular wind measurement and hard target (i.e., vessel) detection, were developed for a preoperational demonstration.

Results confirmed the long-held paradigm that H. wrightii and S. filiforme recover from disturbance significantly faster than Thalassia. The experimental results predicted that T. testudinum meadows in soft carbonate mud banks would recover from simulated mechanical disturbance in 17 to 26 years, much slower than previously reported for silicious sediments.

Extreme events such as storms can quickly result in turnover of seagrass habitat half again as much as experienced in a year. If such storm events are not recognized in surveys, they will make detection of anthropogenic injuries to seagrasses difficult, if not impossible. Restoration efforts will also be hampered, making areas prone to high disturbance candidates for special protection from injury.

Available data for physical, biological, and anthropogenic factors in Cook Inlet are summarized followed by a provisional description of seasonal habitat associations. To summarize habitat preferences, the beluga summer distribution pattern was used to partition Cook Inlet into three regions. In general, belugas congregate in shallow, relatively warm, low-salinity water near major river outflows in upper Cook Inlet during summer (defined as their primary habitat), where prey availability is comparatively high and predator occurrence relatively low. In winter, belugas are seen in the central inlet, but sightings are fewer in number, and whales more dispersed compared to summer. Belugas are associated with a range of ice conditions in winter, from ice-free to 60% ice-covered water. Natural catastrophic events, such as fires, earthquakes, and volcanic eruptions, have had no reported effect on beluga habitat, although such events likely affect water quality and, potentially, prey availability. Similarly, although sewage effluent and discharges from industrial and military activities along Cook Inlet negatively affect water quality, analyses of organochlorines and heavy metal burdens indicate that Cook Inlet belugas are not assimilating contaminant loads greater than any other Alaska beluga stocks. Offshore oil and gas activities and vessel traffic are high in the central inlet compared with other Alaska waters, although belugas in Cook Inlet seem habituated to these anthropogenic factors. Anthropogenic factors that have the highest potential negative impacts on belugas include subsistence hunts (not discussed in this report), noise from transportation and offshore oil and gas extraction (ship transits and aircraft overflights), and water quality degradation (from urban runoff and sewage treatment facilities). Although significant impacts from anthropogenic factors other than hunting are not yet apparent, assessment of potential impacts from human activities, especially those that may effect prey availability, are needed.

Concentrations of total PCB's ( capital sigma PCB's), total DDT ( capital sigma DDT), chlordane compounds, hexachlorobenzene (HCB), dieldrin, mirex, toxaphene, and hexachlorocyclohexane (HCH) measured in Cook Inlet beluga blubber were compared with those reported for belugas from two Arctic Alaska locations (Point Hope and Point Lay), Greenland, Arctic Canada, and the highly contaminated stock from the St. Lawrence estuary in eastern Canada. The Arctic and Cook Inlet belugas had much lower concentrations ( capital sigma PCB's and capital sigma DDT were an order of magnitude lower) than those found in animals from the St. Lawrence estuary. The Cook Inlet belugas had the lowest concentrations of all ( capital sigma PCB's averaged 1.49 plus or minus 0.70 and 0.79 plus or minus 0.56 mg/kg wet mass, and capital sigma DDT averaged 1.35 plus or minus 0.73 and 0.59 plus or minus 0.45 mg/kg in males and females, respectively). Concentrations in the blubber of the Cook Inlet males were significantly lower than those found in the males of the Arctic Alaska belugas ( capital sigma PCB's and capital sigma DDT were about half). The lower levels in the Cook Inlet animals might be due to differences in contaminant sources, food web differences, or different age distributions among the animals sampled. Cook Inlet males had higher mean and median concentrations than did females, a result attributable to the transfer of these compounds from mother to calf during pregnancy and during lactation. Liver concentrations of cadmium and mercury were lower in the Cook Inlet belugas (most cadmium values were <1 mg/kg and mercury values were 0.704-11.42 mg/kg wet mass), but copper levels were significantly higher in the Cook Inlet animals (3.97-123.8 mg/kg wet mass) than in Arctic Alaska animals and similar to those reported for belugas from Hudson Bay. Although total mercury levels were the lowest in the Cook Inlet population, methylmercury concentrations were similar among all three groups of the Alaska animals examined (0.34-2.11 mg/kg wet mass). As has been reported for the Point Hope and Point Lay belugas, hepatic concentrations of silver were relatively high in the Cook Inlet animals and positively correlated with mercury and selenium concentrations in the liver.

These banks are approximately 175 km southeast of Galveston, Texas at 28 degree north latitude and support the northernmost coral reefs on the North American continental shelf. The East and West Flower Garden Banks (EFG and WFG) and Stetson Bank, a smaller sandstone bank approximately 110 km offshore, are managed and protected as the Flower Garden Banks National Marine Sanctuary (FGBNMS). As part of a region-wide initiative to assess coral reef condition, the benthic and fish communities of the EFG and WFG were assessed using the Atlantic and Gulf Rapid Reef Assessment (AGRRA) protocol. The AGRRA survey was conducted during a week-long cruise in August 1999 that was jointly sponsored by the FGBNMS and the Reef Environmental Education Foundation (REEF). A total of 25 coral transects, 132 algal quadrats, 24 fish transects, and 26 Roving Diver (REEF) surveys were conducted. These surveys revealed reefs with high coral cover, dominated by large, healthy corals, little macroalgae, and healthy fish populations. The percent live coral cover was 53.9 and 48.8 at the WFG and EFG, respectively, and the average colony diameter was 93 and 81 cm. Fish diversity was lower than most Caribbean reefs, but large abundances and size of many species reflected the low fishing pressure on the banks. The benthic and fish assemblages at the EFG and WFG were similar. Due to its near pristine conditions, the FGB data will prove to be a valuable component in the AGRRA database and its resulting scale of reef condition for the region.

Fish resource exploitation at Navassa Island has been minimal because of its remote location and lack of human habitation. Some 57 reef fish taxa, three shark species, and three incidental catch species were identified. Continued monitoring of fish resources at this location can provide researchers with opportunities to study relatively unexploited marine habitats.

A rigid grate for excluding Pacific halibut from such catches was assessed in Alaskan waters. Excluder components and sampling procedures are described. The halibut excluder grate system dramatically reduced halibut bycatch, particularly for halibut larger than 5 kg. Catches of rex sole, Dover sole, and flathead sole were reduced moderately. Reductions in halibut bycatch rates using excluders would allow harvesting of a greater percentage of target flatfish quotas, because halibut bycatch limits have led to closures in each year that halibut limits were set.

In 2 seasons (spring and fall) of high nekton abundance, and over 2 yr, we collected 267 quantitative samples (upper Galveston Bay, 1993 = 127 and East Bay, 1994 = 140) using a 1 m super(2) drop sampler. The vegetated marsh surface consistently contained more species (i.e. higher species richness) and total numbers of decapod crustaceans than nonvegetated areas. In contrast, fish species richness and densities of total fishes on the marsh and in nonvegetated areas were not significantly different in most comparisons. Most numerically dominant species of nekton seemed to exhibit at least some degree of habitat selection. Within vegetation, 2 factors, elevation and proximity to open water, were most important in influencing the distribution of nekton. Low marsh edge dominated by Spartina alterniflora or Scirpus maritimus was apparently selected by most species that used the marsh surface including brown shrimp Farfantepenaeus aztecus, blue crab Callinectes sapidus, and daggerblade grass shrimp Palaemonetes pugio. White shrimp Litopenaeus setiferus and striped mullet Mugil cephalus also were concentrated in low edge marsh; although in one comparison, densities of these 2 species in edge and inner S. alterniflora were not significantly different. In contrast, gulf killifish Fundulus grandis and sheepshead minnow Cyprinodon variegatus were most abundant on inner S. alterniflora or S. patens marsh. Other fishes (gulf menhaden Brevoortia patronus, spot Leiostomus xanthurus, bay anchovy Anchoa mitchilli, blackcheek tonguefish Symphurus plagiusa, and Atlantic croaker Micropogonias undulatus) had higher densities over nonvegetated bottoms than on the marsh surface. Specific habitat types that these pelagic species seemed to favor were marsh channels (gulf menhaden, bay anchovy), marsh ponds (spot), and coves (Atlantic croaker, blackcheek tonguefish). Overall, marsh-surface and adjacent nonvegetated habitat types contained much higher densities of most nekton than the shallow bay. Infaunal densities were estimated from sediment cores, and taxa (mainly annelids, crustaceans, molluscs, and insects) were most abundant in nonvegetated areas contiguous with marsh in the spring. Factors that influenced infaunal abundance are complex and may include predation, flooding patterns, elevation, and distance to edge. Our study has important implications for designing marsh-creation projects. Based on our results, we recommend creating a variety of marsh and contiguous shallow-water areas to enhance nekton biodiversity. To maximize fishery habitat, priority should be given to constructing low marsh edge by creating large areas of low marsh interspersed with a dense network of shallow channels and interconnected ponds.

To date, no mobile genetic elements have been reported for this pathogen. Here, we describe the first insertion sequence (IS) identified from R. salmoninarum. This element, IS994, has a significant predicted amino acid sequence homology (64.8 and 71.9%) to the two open reading frames encoding the transposase of IS6110 of Mycobacterium tuberculosis. Protein parsimony and protein distance matrix analyses show that IS994 is a member of group IS51 of the IS3 family. From a conservative estimate, there are at least 17 chromosomal insertions of IS994 or closely related elements. Sequence analysis of seven of these loci reveals single nucleotide polymorphisms throughout the element (including the terminal inverted repeats), a 15 bp insertion in three of the seven loci, and an absence of flanking direct repeats or conserved insertion site. Restriction fragment length polymorphism analysis of XbaI-digested chromosomal DNA shows variations among European and North American isolates, indicating that IS994 may be a useful molecular marker for epizootiological studies.

To facilitate comparison, the ratio (J sub(o)/k) of the initial pure water flux J sub(o) to the estimated boundary layer mass transfer coefficient k was used to define similar initial hydrodynamic operating conditions for the three different membranes. The membranes showed differences in NOM rejection when filtering hydrophilic NOM-source water, and also exhibited differences in flux decline with the hydrophobic NOM-source water. Flux decline and NOM rejection were quantified using a resistances-in-series model and effective molecular mass cut-off, respectively. Non-charged NOM fractions (hydrophilic and hydrophobic neutrals/bases) were found to be significant foulants for these negatively charged membranes.

The highest levels of supersaturation result from high springtime river flows and turbine outages, conditions over which there is little control and that cause high volumes of water passing over the dams and through spillways instead of through turbines. During the spring freshets of 1994-1997, we surveyed nonsalmonid fishes and invertebrates for signs of gas bubble disease (GBD) and conducted holding experiments in three river reaches where gas saturation commonly exceeds 120%. We developed a dissolved-gas exposure index for nonsalmonid fishes sampled at specific times and locations; mean daily total dissolved-gas saturation (TDGS) was ranked and then summed over a 7-d period. We analyzed observations of 39,924 nonsalmonid fishes in an iterative process, which led to development of a mathematical equivalence model for TDGS duration and level of exposure that was strongly correlated with prevalence of GBD signs (R super(2) = 0.79). We believe this simple model is a reliable predictor of external GBD signs resulting from prolonged exposure to supersaturated dissolved gas in the Columbia and Snake rivers. When TDGS levels were below 120%, GBD signs in fish were rare; when TDGS levels exceeded 120%, the model reliably predicted the extent to which fish displayed external GBD signs. In addition, we attempted to evaluate GBD-related mortality over the 4 years of net-pen holding experiments. However, due to the high variability we observed in these evaluations and the paucity of dead fish recovered from these rivers, we concluded that an accurate model relating TDGS to mortality could not be developed using these methods.

These cements do not have sufficient tensile strength or fracture toughness to allow their use in stress-bearing applications. It was hypothesized that a bioresorbable fiber mesh would improve the load-bearing behavior of shell structures fabricated of CPC. This study used a biaxial flexure fixture to compare the work-to-fracture values of discs made of: (1) CPC; (2) CPC reinforced with a bioresorbable two-dimensionally oriented poly(glactin) fiber-mesh; and (3) poly(methyl methacrylate) (PMMA) that were immersed in a serum-like solution for 0-28 days. CPC-mesh and PMMA discs were indistinguishable at 0, 1 and 7 days, based on work-to-fracture data. CPC and CPC-mesh discs were indistinguishable at day 28, because of fiber hydrolysis. The knitted fiber-mesh was effective in improving load-bearing behavior of a calcium phosphate cement for potential structural repair of bone defects.

AN - 70907355; 10680356 AB - Several ozone modeling approaches were investigated to determine if uncertainties in the meteorological data would be sufficiently large to limit the application of physically realistic ozone (O3) forecast models. Three diagnostic schemes were evaluated for the period of May through September 1997 for Houston, TX. Correlations between measured daily maximum and model calculated O3 air concentrations were found to be 0.70 using a linear regression model, 0.65 using a non-advective box model, and 0.49 using a three-dimensional (3-D) transport and dispersion model. Although the regression model had the highest correlation, it showed substantial underestimates of the highest concentrations. The box model results were the most similar to the regression model and did not show as much underestimation. The more complex 3-D modeling approach yielded the worst results, likely resulting from O3 maxima that were driven by local factors rather than by the transport of pollutants from outside of the Houston domain. The highest O3 concentrations at Houston were associated with light winds and meandering trajectories. A comparison of the gridded meteorological data used by the 3-D model to the observations showed that the wind direction and speed values at Houston differed most on those days on which the O3 underestimations were the greatest. These periods also tended to correspond with poor precipitation and temperature estimates. It is concluded that better results are not just obtained through additional modeling complexity, but there needs to be a comparable increase in the accuracy of the meteorological data.

Our understanding of LGM conditions in the region has been hampered by low site density, problems of data quality (particularly dating), and the possibility that LGM vegetation and climate lacked modern analogs. In order to generate improved reconstructions of LGM vegetation and environment, we assembled pollen and plant macrofossil data from 21 and 17 well-dated LGM sites, respectively. All sites have assemblages within the LGM timespan of 21,000+ or -1500 calendar yr BP. Based on these data, we prepared maps of isopolls, macrofossil presence/absence, pollen-analogs, biomes, inferred mean January and July temperatures and mean annual precipitation for the LGM. Tundra and open Picea-dominated forest grew along the Laurentide ice sheet, with tundra predominantly in the west. In the east, Pinus-dominated vegetation (mainly P. banksiana with local P. resinosa and P. strobus) occurred extensively to 34 degrees N and possibly as far south as 30 degrees N. Picea glauca and a now-extinct species, P. critchfieldii, occurred locally. Picea-dominated forest grew in the continental interior, with temperate hardwoods (Quercus, Carya, Juglans, Liriodendron, Fagus, Ulmus) growing locally near the Lower Mississippi Valley at least as far north as 35 degrees N. Picea critchfieldii was the dominant species in this region. The Florida peninsula was occupied by open vegetation with warm-temperate species of Pinus. Eastern Texas was occupied by open vegetation with at least local Quercus and Picea. Extensive areas of peninsular Florida and the continental interior had vegetation unmatched by any modern pollen samples. The paleovegetational data indicate more extensive cooling in eastern North America at the LGM than simulated by either the NCAR CCM0 or CCM1 climate models. The occurrence of cool-temperate conifers and hardwoods as far north as 34-35 degrees N, however, indicates less severe cooling than some previous reconstructions. Paleoclimate inferences for the LGM are complicated by lowered atmospheric CO (sub 2) concentrations, which may be responsible for the open nature and dominance of conifers in LGM vegetation.

It is shown that the annual mean climatology of the surface air temperatures (SAT) in all three models is realistic and the linear trends over the 1000-yr integrations are small over most areas of the globe. Second, although there are notable differences among the models, the models' SAT variability is fairly realistic on annual to decadal timescales, both in terms of the geographical distribution and of the global mean values. A notable exception is the poor simulation of observed tropical pacific variability. In the HadCM2 model, the tropical variability is overestimated, while in the GFDL and HAM3L models, it is underestimated. Also, the ENSO-related spectral peak in the globally averaged observed SAT differs from that in any of the models. The relatively low resolution required to integrate models for long time periods inhibits the successful simulation of the variability in this region. On timescales longer than a few decades, the largest variance in the models is generally located near sea ice margins in high latitudes, which are also regions of deep oceanic convection and variability related to variations in the thermohaline circulation. However, the exact geographical location of these maxima varies from model to model. The preferred patterns of interdecadal variability that are common to all three coupled models can be isolated by computing empirical orthogonal functions (EOFs) of all model data simultaneously using the common EOF technique. A comparison of the variance each model associated with these common EOF patterns shows that the models generally agree on the most prominent patterns of variability. However, the amplitudes of the dominant modes of variability differ to some extent between the models and between the models and observations. For example, two of the models have a mode with relatively large values of the same sign over most of the Northern Hemisphere midlatitudes. This mode has been shown to be relevant for the separation of the temperature response pattern due to sulfate aerosol forcing from the response to greenhouse gas forcing. This indicates that the results of the detection of climate change and its attribution to different external forcings may differ when unperturbed climate variability in surface air temperature is estimated using different coupled models. Assuming that the simulation of variability of the global mean SAT is as realistic on longer timescales as it is for the shorter timescales, then the observed warming of more than 0.5 K of the SAT in the last 110 yr is not likely to be due to internally generated variability of the coupled atmosphere-ocean-sea ice system. Instead, the warming is likely to be due to changes in the radiative forcing of the climate system, such as the forcing associated with increases in greenhouse gases.

Comparison of the water and tissue concentrations associated with decreased survival revealed large differences in toxicity among the three compounds. In H. azteca, the ratio of the 10-d LR50 values (median lethal tissue residue) for DDT: III:DDE was 1:24:195. In Diporeia spp., the 28-d LR50 for DDT was higher than that for III by a factor of six, and DDE did not cause significant mortality even at concentrations approaching the solubility limit. Based on the toxicity data, the hazard from exposure to mixtures of DDT and its degradation products should be evaluated on a toxic-units basis and not as a simple summation of the individual concentrations, which ignores the toxicity of specific compounds. Differences in species sensitivity were also detected. The 10-d LR50 values were higher in Diporeia spp. than in H. azteca by a factor of 40 for DDT and eight for III. This difference can be only partly attributed to differences in lipid content between H. azteca (7% dry wt) and Diporeia spp. (24% dry wt). The uptake clearance and elimination rate constants were similar among the various compounds in both species. Uptake clearance was typically fourfold greater for H. azteca than for Diporeia spp., however, and the experimentally measured elimination rate was approximately 30-fold greater in H. azteca than in Diporeia spp. The larger rates of uptake and elimination were attributed to the higher exposure temperature, greater surface area-to-volume ratio, and lower lipid content for H. azteca compared with Diporeia spp. In addition, extensive biotransformation of DDT by H. azteca may have contributed to a more rapid compound elimination.

In May, the majority of RCs in liver were seen in blood vessel endothelium, while in August most cells were located in the epithelium of the intrahepatic biliary ducts. In kidney, a significant increase in RCs in the columnar epithelium of the collecting ducts was observed from May to August. RCs in spleen were extremely rare in May, but were seen frequently in the endothelium of the splenic blood vessels in August. In gill and intestine, RCs were found in every tissue sample studied, with no statistical differences in their abundance or distribution between seasons. No RCs were seen in gonads. Total numbers of RCs increased dramatically from May to August in kidney and in spleen. The frequency of RCs corresponded strongly with the current phase of parasitic infections in liver, kidney, and spleen. It is concluded that RCs play a role in host defence mechanisms in fish, displaying induced expression at the times of peak parasitic prevalences.

Data are used to enhance Sanctuary goals of research, education, and resource management. The aerial monitoring program allows near-realtime collection of data vital to coastal zone management and resource protection. Collected floral and faunal data are used to monitor kelp distribution; marine mammal populations and migration patterns; and general resource health within the Sanctuary. Vessel traffic and type surveys allow anthropogenic use patterns to be studied. Data downloaded into the Sanctuary's GIS are used to analyze historical trends and detect correlations across data types. Maps are created and made available via the World Wide Web as a public education tool. Additionally, the program is being prototyped as a response tool for resource emergencies such as oil spills. Data collected on spill perimeter changes, oil types, and oiled animals can be downloaded to a portable GIS at Unified Command Centers to aid in both immediate response decisions and long term impact analysis.

N1 - Last updated - 2014-05-06 ER - TY - JOUR T1 - Breaching of a Small Irrigation Dam in Oregon: A Case History AN - 17823656; 4856787 AB - Dam removal or breaching (partial removal) is an increasingly common remedy for fish passage, habitat degradation, water quality, and other problems caused by dams in the United States. The Jackson Street Dam, built in 1960 on Bear Creek in Medford, Oregon, resulted in a barrier to migration of Pacific salmon Oncorhynchus spp. and steelhead O. mykiss, loss of stream habitat, eutrophication, and an algae-choked impoundment in downtown Medford. The 11-ft-high concrete and wooden structure was owned and operated by the Rogue River Valley Irrigation District as one of its primary diversions. The dam was breached in 1998, culminating a 13-year, US$1.2 million effort led by the Rogue Valley Council of Governments and the Medford Urban Renewal Agency in collaboration with the irrigation district, other government agencies, and local citizens. Breaching reduced the dam to a series of three concrete steps dropping 1 ft each, thereby providing fish passage and restoring a free-flowing stream within the former impoundment. Before the dam was breached, a replacement diversion was built upstream of the dam site to provide water to the irrigation district. The new 3-ft-high diversion is equipped with effective fish passage facilities and is removed from October to April when irrigation is not needed. Major factors affecting the project were the large number of stakeholders with conflicting missions, underestimation of the project's cost and time frame, tests of the new diversion before breaching of the old dam, perseverance of key project supporters, and lack of opposition to the project. Lessons learned from the project include the importance of stakeholder collaboration, selection of a volunteer lead agency or organization, consideration of the project owner's needs, education of the public about the project, accurate budget development, and setting realistic expectations. A set of 10 recommendations is provided for the planning and implementation of similar efforts, based on the lessons learned from this and other successful dam removal or breaching projects.

In contrast to the polarimetric algorithm based on specific differential phase K sub(DP), the proposed method does not require rain-rate estimation from K sub(DP) inside the area of interest, but it utilizes only values of total differential phase Phi sub(DP) on the areal contour. Even if the radar reflectivity and differential phase data inside the area are corrupted by ground clutter, anomalous propagation, biological scatterers, or hail contamination, reliable areal rainfall estimate is still possible, provided that correct Phi sub(DP) estimates are available at a relatively small number of range locations in or at the periphery of the contour of this area. This concept of areal rainfall estimation has been tested on the Little Washita River watershed area in Oklahoma that contains 42 densely located rain gauges. The areal rainfall estimates obtained from the polarimetric data collected with the 10-cm Cimarron radar are in good agreement with the gauge data, with the standard error of about 18%. This accuracy is better than that obtained with the algorithm utilizing areal averaging of pointwise estimates of K sub(DP) inside the watershed area.

AN - 17597280; 4701550 AB - 1. The Mediterranean monk seal is an endangered marine mammal with only a few populations thought to be viable. The largest aggregation of this species is found at the Peninsula of Cap Blanc, on the Western Sahara, where a colonial structure is maintained. The size of this colony is estimated by annual capture-recapture surveys, but it is unclear if the attained level of precision is enough to detect changes in numbers in the short term. 2. In this study, simulated capture-recapture experiments were used to investigate the relationship between population estimates and abundance. The statistical power necessary to detect a population decline with ongoing surveys was estimated, and the requirements for an improvement in precision were evaluated. Additionally, changes in abundance over consecutive surveys were examined for comparison with an alternative method of Bayesian inference. 3. Results indicated that the power to detect trends from the actual surveys was lower than should be required for the conservation of a small population, such as the colony at Cap Blanc. A 5% annual rate of decline in abundance would only be detected with high power after 12 years, with a population of 317 seals being reduced to 172. If the annual rate of decline was 10%, 8 years would be required to detect a reduction of 317 to 136 seals. 4. Capture-recapture surveys can produce reliable data but do not identify moderate or low population declines. The increase in precision of surveys is costly and time consuming, and other monitoring methods are needed to detect early signs of a decline. Bayesian methods cannot provide a better result because they are not robust to small sample size and heterogeneity in capture probabilities. Despite the need for alternative methods for earlier detection, capture-recapture surveys are still required to estimate the size of the colony, and precision in population estimates can be evaluated in relation to cost effectiveness.

A total of 598 red drum ranging from 291-763 mm total length were collected and their stomach contents analyzed during fall 1997 and spring 1998. The diet of red drum showed significant seasonal patterns, and was dominated by white shrimp (Penaeus setiferus) during fall and Gulf menhaden (Brevoortia patronus) during spring. Blue crab (Callinectes sapidus) was an important component of red drum diets during both seasons. Significant differences existed between prey types consumed during fall and spring as red drum diet reflected seasonal variation in prey availability. Predictive regression equations were generated to estimate original carapace width of blue crabs from several measurements taken from carapace fragments recovered in red drum stomachs. Regressions were highly significant (r super(2) > 0.97) and increased the number of blue crabs with size information nearly three fold. Predator size-prey size relationships were determined for red drum feeding on white shrimp, gulf menhaden, and blue crab. Although regression slopes were statistically significant, prey sizes increased only slightly with increasing red drum size. Comparisons of prey sizes consumed by red drum with sizes occurring in the field indicate that red drum feed in nearshore shallow water habitats, which serve as nursery areas for many juvenile fishes and crustaceans. Our findings demonstrate that red drum feed on several prey species of commercial and recreational value and may have important effects on estuarine community structure.

Colonization of these created reefs by oysters and other select taxa was examined. Created reefs supported numerous oyster reef-associated faunas at equivalent or greater densities than adjacent natural reefs. Eastern oyster (Crassostrea virginica) settlement at one site of created reef exceeded that of the adjacent natural reefs within 9 mo of reef creation. After only 2 yr, harvestable-size C. virginica (>75 mm) were present in the created reefs along with substantial numbers of C. virginica clusters. The created reefs also had a higher number of molluscan, fish, and decapod species than the adjacent natural reefs. After 2 yr the densities of C. virginica, striped barnacle (Balanus amphitrite), scorched mussel (Brachidontes exustus), Atlantic ribbed mussel (Geukensia demissa), common mud crab (Panopeus herbstii), and flat mud crab (Eurypanopeus depressus) within the created reefs were equivalent to that of adjacent natural reefs. From these data it is evident that created oyster reefs can quickly acquire functional ecological attributes of their natural counterparts. Because the demand for oysters continues to increase in the face of dwindling natural resources, habitat creation techniques need to evolve and these approaches need to consider the ancillary ecological benefits reef creation may provide. Reef function as well as physical and ecological linkages of oyster reefs to other habitats (marsh, submerged aquatic vegetation, and bare bottom) should be considered when reefs are created in order to provide the best use of resources to maintain the integrity of estuarine systems.

Structural studies provide one means of obtaining functional information in these cases. A 'structural genomics' project has been initiated aimed at determining the structures of 50 hypothetical proteins from Haemophilus influenzae to gain an understanding of their function. Each stage of the project - target selection, protein production, crystallization, structure determination, and structure analysis - makes use of recent advances to streamline procedures. Early results from this and similar projects are encouraging in that some level of functional understanding can be deduced from experimentally solved structures.

The time has come to take stock. Decade framers set forth three targets for each nation: hazard identification and risk assessment; a mitigation strategy, couched in terms of plans for sustainable development; and improved warning and dissemination. By this yardstick, the U.S. experience was moderately successful. Public awareness of natural hazards is growing rapidly. Correspondingly, national policies toward natural disasters are shifting dramatically - aligning better with the nature of the problem as experts currently understand it. The 1990s saw natural hazards lose much of the element of surprise; today, natural extremes are forecast and their threats anticipated more successfully than ever before. However, despite this progress, losses in the United States due to natural disasters continued to rise sharply during the decade. More ominously, the nature and profile of disasters and their losses appear to be mutating in response to rapid societal change. Advances in our understanding of the geophysical, engineering, and societal causes of natural disaster, though considerable, seem to be lagging behind these changes. As a result, American citizens are no safer they than were a decade ago. Local and regional economies are proving too vulnerable to disruption; even the national economy may be significantly affected under some scenarios. Major obstacles will continue to challenge U.S. efforts to reduce natural disasters in the decades ahead.

Protection trawl survey data collected during 1984-94. Seasonal distribution maps for59 species, abundance data for 41 species, and length frequencies for 26 species are presented. Seasonal migration patterns and preference for particular areas within Long Island Sound were evident for many species, and overall abundance was lower in the eastern vs. central and western regions of the sound. Species richness was highest within the central area of the sound and lowest in eastern habitats, while aggregate mean catch was highest in the western and central habitats and declined eastward.

AN - 36406686; 7868 AB - PURPOSE: The implementation of channel improvement throughout the Port of New York and New Jersey is proposed. The project area would include the South Brooklyn Marine and Red Hook container terminals, Staten Island, and adjacent areas. The channel improvements would be undertaken to meet the changing trend toward larger cargo vessels in the world fleet. Projections of the volume of commerce passing through the port over the period extending from 2010 to 2060 exceed port capacity, with or without channel improvements. Several alternatives are considered including a No Action Alternative, non-structural alternatives, and structural alternatives. The recommended plan would provide for navigation improvements affecting nine channels (Ambrose, Anchorage, Bay Ridge, Port Jersey, Kill Van Kull, Newark Bay, Elizabeth, South Elizabeth, and Arthur Kill channels), which would permit access by larger, deeper-draft vessels to four main container terminals. The improvements would consist of channel deepening, channel realignment, turning basin construction, and berth deepening. No expansion of port facilities would be directly attributable to the recommended plan. Economic forecasts project an increase in port commerce regardless of whether navigation improvements are implemented. The project would last eight to 12 years. The estimated initial cost of the project is $1.8 billion, and the estimated benefit-cost ratio is 1.4. POSITIVE IMPACTS: Increasing the depth of the existing channels in the port would allow the passage of deeper-draft vessels, ensuring the continued viability of the port in the face of a changing world fleet. NEGATIVE IMPACTS: The primary adverse impact related to the project would consist of the loss of shallow water habitat. Navigation improvement would disturb existing channel habitat and change some shallow areas to deeper habitat. The recommended plan would disturb 6.26 acres of littoral zone habitat. Of this total, 3.23 acres would lie in the channel from Arthur Kill to Howland Hook, 2.72 acres adjacent to the Newark Bay Channel, 0.25 acres in the South Elizabeth Channel, and 0.06 acres in Kill Van Kull Channel. The recommended plan would disturb 42.03 acres of sublittoral zone habitat. Of this total, 12.35 acres in the Jersey Flats near the Port Jersey Channel, 1.41 acres in the Kill Van Kull Channel, 3.22 acres in the channel from Arthur Kill to Howland Hook, 7.79 acres in Newark Bay Channel, 15.84 acres in the South Elizabeth Channel, and 1.42 acres in the Elizabeth Channel. Slight increases in salinity and decreases in dissolved oxygen levels would result from channel deepening.

Preparation date: January 18, 2000 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - ISSUANCE OF A MULTIPLE SPECIES INCIDENTAL TAKE PERMIT FOR THE TACOMA WATER HABITAT CONSERVATION PLAN, GREEN RIVER WATER SUPPLY OPERATIONS AND WATERSHED PROTECTION, KING COUNTY, WASHINGTON. AN - 36393423; 7858 AB - PURPOSE: The issuance of an incidental take permit for 32 federally listed and unlisted species using habitat in and around the Green River downstream of the headworks diversion operated by the City of Tacoma Water Division (Tacoma Water), located in west-central Washington, is proposed. The permit would be issued for a period of 50 years. The permit was requested by Tacoma Water because activities associated with its water withdrawals and land management activities could, in the opinions of the U.S. Fish and Wildlife Service (FWS), result in the take of listed species and/or impacts to unlisted species that could become listed during the term of the permit. Tacoma Water believes that regulations promulgated for the conservation of these listed species, and those that may become listed, could result in the severe curtailment of water withdrawal activities at the Tacoma headworks and/or the severe limitation or cessation of timber logging. Tacoma Water has informed the FWS that the curtailment of water withdrawal activities would have severe consequences on the reliability of its water supply, which serves approximately 83,000 service customers (approximately 300,000 persons) and provides critical public water supply infrastructure to the communities in Pierce and south King counties. In addition, Tacoma Water has indicated that potential reductions in timber logging and the concomitant reduction of revenues would adversely affect its ability to manage its lands in the upper watershed. Three alternatives, including a No Action Alternative (Alternative A), are considered in this draft EIS. The proposed action (Alternative B) would involve the issuance of the permit and require that Tacoma Water develop and implement a habitat conservation plan. Alternative C would involve the construction and operation of a diversion at approximately river mile 29.2 and also require a habitat conservation plan by Tacoma Water. POSITIVE IMPACTS: The allowing of incidental take of the affected species would provide Tacoma with the ability to provide crucial water supply services and continue to take economic advantage of timber logging within the Green River watershed. The habitat conservation plan would ensure protection of the affected species. In-stream geomorphologic processes would improve, and minimum flow agreements would marginally benefit water quality during summer low-flow periods. Certain habitat values would increase, and fish passage would be enhanced. More preferred days for whitewater rafting and kayaking would be available in the average May. NEGATIVE IMPACTS: Flows would be reduced during March and into mid-April, adversely affecting salmon spawning and rearing habitat. Side channel spawning habitat and rearing area would decrease for Chinook, coho, and chum salmon, as well as steelhead and cutthroat trout. Bull trout and Dolly Varden spawning and rearing habitat would be adversely affected. Approximately seven acres of upland forest habitat would be lost due to the expansion of the Tacoma headworks inundation pool, which would also adversely affect wetland habitat. Hardwood forest acreage would decrease overall. Approximately 52 percent of the existing spotted owl habitat would not be protected from logging, and an additional 135 acres would be available for logging in the short term. The habitat for olive-sided flycatchers would decrease. The mortality of Cascades frogs could occur during logging in suitable habitat. Fewer preferred days for whitewater rafting and kayaking would be available in the average March. Water supply costs would increase due to the cost of new facilities. With increased sediment, solids, particulates, dissolved organic matter, and nutrient, the logging and the road construction, maintenance, and use would adversely affect surface water quality.

The authors used surgically implanted acoustic tags to track 17 net-pen reared juvenile chinook salmon (Oncorhynchus tshawytscha), fork-lengths 150-169 mm, from the Colombia River estuary to the ocean. The 300 kHz tags had a pulse-coding scheme, measured 18 mm long by 8 mm in diameter, and weighed 1.5 g in air (0.35 g in water). Receiving equipment consisted of electronic receivers and passive induction-style directional hydrophones with 20 or 30 degree beam widths. Acoustic tags utilized in saltwater or brackish-water environments were limited in both detection range (100 m) and tag life (30 days). Generally, fish were released individually at River Kilometer (RKm) 29 or 11 and tracked using 2 boats. Movement of tagged fish was associated with prevailing tidal current: fish released near high tide moved downstream with the ebb current: fish released near low tide moved upstream with the flood current (2.6km/h average maximum ebb/flood velocities). Tracking efforts extending across multiple tide changes supported the conclusion that movement of tagged fish was primarily related to tidal current. Fish generally remained stationary during periods of low current, and movements seemed less affected by diurnal photoperiod than by tidal currents.

AN - 71207880; 10868075 AB - The available data indicate that sediment-water partitioning, bioaccumulation, and the toxicity responses for tributyltin (TBT) are predictable when using some of the assumptions and tenets of the equilibrium partitioning method, toxicokinetic modeling (1CFOK), and critical body residue (CBR) approach. Because TBT is ionizable, its speciation is strongly affected by pH, which appears to cause large variations in the octanol-water partition coefficient. In marine systems, and in freshwater systems with high pH, TBT occurs predominantly in the hydroxide form, which may explain the hydrophobic properties and its EqP behavior. Organic carbon in sediment (> 0.2%) appears to be the major controlling factor for sediment-water partitioning. The equilibrium organic carbon-normalized sediment-water partition coefficient (Koc) in marine environments is approximately 32,000 (log10 Koc approximately 4.5), which was determined from direct measurement and confirmed by the relationship between the lipid-normalized bioconcentration factor (BCF) in porewater and the biota-sediment accumulation factor (BSAF). The conclusion that sediment-water partitioning of TBT in marine systems follows EqP is supported by the similarity between its Kow and Koc and the correlation between the sediment-water partition coefficient (Kp) and sediment TOC, which results from the influence of organic carbon on pore-water concentrations. Even though the rates of uptake and elimination control tissue residues and lipid content appears to have no bearing on the amount of TBT that is accumulated, the species specific BSAF is useful for examining bioaccumulation, sediment-water partitioning, and the toxicity response. Although TBT is hydrophobic and appears to have a propensity to accumulate in lipid, the rates of uptake and elimination, not thermodynamics, appear to control whole-body tissue concentrations. Support for a toxicokinetic approach for predicting tissue residues is found in BCF and BSAF values for several species that are far in excess of that predicted by simple thermodynamic partitioning and in the comparisons of observed and predicted bioaccumulation values based on toxicokinetic coefficients. This observation is counter to the assumption of EqP that the route of uptake is of no consequence under equilibrium conditions. For TBT, it appears that kinetics determine tissue residues and that body lipid is important only for regulating the toxic response, not the amount bioaccumulated. Unlike those for neutral hydrophobic organic compounds, the toxicokinetics for this one toxicant are highly variable in diverse species but relatively accurate in predicting the amount bioaccumulated and the resulting toxicity response. For the CBR approach to be useful, a relatively constant tissue residue for a given biological response is necessary. Several studies support the CBR approach because certain biological effects, such as mortality and growth inhibition, occur at a relatively constant TBT tissue concentration. For TBT, the lethal whole-body tissue concentration affecting 50% of individuals (LR50) exhibits little variation, occurring at approximately 48 micrograms/g (166 nmol/g) dry weight in a range of species. Direct evidence and correlation of the LC50 and the bioconcentration factor (BCF) support this observation. Impaired growth, a sublethal response, also appears to be associated with a relatively constant tissue concentration, which has also been demonstrated by direct measurement and indirectly by regression of the BCF and LOEC. The lowest-observed-effect tissue residue (LOER) associated with impaired growth for several species was approximately 3 micrograms/g (10.4 nmol/g) dry wt. Because of the small number of studies linking growth impairment and tissue concentrations, additional studies are needed to confirm these values.

Logistic regressions are used to predict the likelihood of divorce or separation of the couple by Wave 2. In addition to socioeconomic variables, the NSFH also contains measures of the degree of connection with family members & marital conflict, factors that can help explain why interracial marriages are more likely to disrupt than endogamous marriages. The analysis introduces into the models characteristics that predict a higher chance of divorce for interracial couples & characteristics that predict a lower chance of divorce for interracial couples. Although interracial marriages are more likely to experience disruption than endogamous marriages, being in an interracial marriage is a less important predictor of divorce or separation than other factors that generally increase the risk of marital disruption, for example, low socioeconomic status, teenage marriages, & low educational attainment.

The debate revolves around what is the most appropriate unit -- the family, the household, or some other entity. This analysis discusses the existing options & offers a conceptually more refined alternative: the "family/couple/household" (FCH) unit, which assumes income pooling among family members, including cohabiting couples, but not among nonrelatives, & takes into account the benefits from economies of scale for all household members. Poverty rates are estimated using alternative definitions. Overall, empirical results show modestly lower poverty rates when household-level economies of scale are taken into account. The difference is largest for persons living in nontraditional household arrangements, such as cohabitors & non-family members. 3 Tables, 1 Figure, 15 References. Adapted from the source document.

White, black, Mexican, or Asian spouses in black-white, Mexican-white or Asian-white unions were compared to intramarried couples based on data from the 1988 National Survey of Families & Households. The final sample included 4,522 married couples. The results suggest that differences in marital happiness & perceived stability between intermarried & intramarried couples vary by race/ethnicity & gender. Our findings indicate that only interracially married white females reported significantly lower marital happiness & stability than their intramarried counterparts. Conversely, spouses in Mexican male-white female & white male-Asian female unions reported significantly higher marital quality &/or stability than their white counterparts. 6 Tables, 35 References.

The instrument used was the Airborne Topographic Mapper (ATM), developed by the NASA Arctic Ice Mapping (AIM) group from the Goddard Space Flight Center's Wallops Flight Facility. In November, 1995, and again in May, 1996, these topographic surveys were flown as a functionality check prior to conducting missions to measure the elevation of extensive sections of the Greenland Ice Sheet as part of NASA's Global Climate Change program. Differences between overlapping portions of both surveys are compared for quality control. An independent assessment of the accuracy of the ATM survey is provided by comparison to surface surveys which were conducted using standard techniques. The goal of these projects is to make these measurements to an accuracy of + or -10 cm. Differences between the fall 1995 and 1996 surveys provides an assessment of net changes in the beach morphology over an annual cycle.

In particular, the role of structure within and among habitats, networks through which organisms and critical processes that influence secondary production operate, and the role of estuarine circulation "control point" features in shaping food-web structure and variability are poorly known. In response to these gaps, the Habitat-Biotic Interactions Working Group established as their goal to identify approaches needed to synthesize a mechanistic understanding of how habitat structure influences estuarine secondary production and food webs. We recommend eight major steps to enhance synthesis of natural and anthropogenic changes in estuarine production related to habitat-biotic interactions: (1) develop an estuarine habitat classification scheme that relates habitat structure to estuarine production and food-web processes; (2) examine existing long-term data sets to identify the scope and frequency of variability in habitat structure; (3) implement comparative studies of habitat function; (4) develop and link habitat and landscape models that capture the dynamics of biota and process interactions over large estuarine scales; (5) develop indicators of ecosystem habitat integrity, dynamics, and variability; (6) link site-specific field experiments and modeling approaches to scale processes and process understanding across ecosystems and landscapes; (7) apply advanced measurement technologies to give details of distributions and abundances of secondary consumers not now achievable; and (8) link habitat structure to assessment and prediction of resource management scenarios. Addressing ecosystem change in response to habitat structure, as well as the impacts of coastal zone management impacts upon ecosystems, will require innovative syntheses at much more expanded time and space scales than heretofore considered.

This chapter summarizes two approaches we have used to investigate the controls on such fluxes. The first is the use of a model, the Generalized Watershed Loading Function (GWLF) model, to evaluate sources of organic carbon to the tidal, freshwater Hudson River estuary. This ecosystem is highly heterotrophic, and heterotrophic respiration is driven largely by allochthonous inputs of organic matter from nonpoint sources. GWLF suggests that the major source of this allochthonous carbon is erosion from agricultural fields. The Hudson Valley was once largely forested, reached a peak of agricultural activity in the early 1900s, and has steadily become more forested again as agricultural land has been abandoned. GWLF indicates that these land-use changes are likely to have resulted in large changes in the metabolism of the freshwater river, with the greatest heterotrophy coinciding with the greatest agricultural activity. The model also suggests that climate change may affect allochthonous inputs to the estuary, since drier soils result in substantially less erosion of agricultural soils. The second approach we describe is a large-scale comparative analysis of nitrogen fluxes in rivers to the estuaries and coastal seas of the North Atlantic Ocean. For this analysis, we divided the watersheds of the North Atlantic Basin into fourteen large regions. Nonpoint sources of nitrogen dominate the flux for all regions. Nitrogen inputs to a region from human activity (import of food, use of inorganic nitrogen fertilizer, nitrogen fixation by agricultural crops, and atmospheric deposition of oxidized nitrogen originating from fossil-fuel combustion) are linearly related to nitrogen export to the coast from the region. On average, only 20% of the human-controlled inputs to a region are exported from the region to coastal waters, and the rest are processed or retained in the landscape. Human activity has probably had substantial effects on increased nitrogen inputs to the coast for some regions, perhaps increasing inputs by some fifteen-fold for the North Sea and tenfold for the northeastern United States. Regression analysis suggests that the deposition of oxidized nitrogen from fossil fuel combustion may be particularly important as a source of nitrogen flowing from the landscape to estuaries; per unit nitrogen input, such deposition appears to contribute disproportionately to riverine flows in comparison to agricultural sources. Regression analysis also suggests that the deposition of ammonia and ammonium from the atmosphere may be a good surrogate measure of the leakage of nitrogen from agricultural systems to surface waters.

We have investigated the relation of perylene to the amount and type of organic matter in the sediments of Saanich Inlet, a coastal marine anoxic basin. Organic matter is predominantly marine in origin, but the proportions of marine and land-derived components have varied. Perylene concentrations generally increase with sediment depth, relative to TOC, which indicates continued formation of this compound by microbially mediated diagenesis. Perylene delta (super 13) C values range between -27.7 and -23.6 per mil, whereas TOC delta (super 13) C values vary narrowly from -21.7 to -21.2 per mil over the same sediment depth interval. The variation in isotopic difference suggests that perylene originates from more than one precursor material, both aquatic and continental organic matter, different microbial processes, or some combination of these possibilities.

Our initial regions have been coral reef communities in the U.S. Virgin Islands and Puerto Rico. We have used a three-dimensional visualization photogrammetric software package, Socet Set, to produce orthophotometric-corrected mosaics. These mosaics are then used by habitat specialists to characterize the shallow water benthos. We are evaluating and developing the techniques for radiometric balancing the images, preserving the rectification precision. Additionally implementing corrections for the refraction of light in water, we have produced subsurface digital elevation models (DEMs) of the coral reefs. We will illustrate the status of our work with a demonstration of the three dimensional workstation environment showing examples of our work.

Since then, the national and some local governments in Japan developed GIS-based damage estimation systems, but few other countries have such systems as yet. Nighttime city lights decreased significantly after a large earthquake, and the DMSP/OLS imagery is suitable for the early estimation of the damaged areas. The damaged areas of the 1999 Kocaeli Earthquake in Turkey and 1999 Ji-Ji Earthquake in Taiwan were estimated by using DMSP, and the results showed a good matched with the real reported damages. We propose a new program through international collaboration to support emergency response and relief activities by providing the information as to the estimated impacted areas within the first 24 hours after any significant earthquake. This program consists of the following steps: 1) Acquire the earthquake hypocenter data through the Internet, which is for example announced by the USGS. 2) Determine the sampled area of images by the attenuation formula of earthquake ground motion. 3) Obtain the corresponding both time-wise and area-wise DMSP/OLS nighttime images from NOAA/NGDC. 4) Estimate the damaged areas by analyzing the statistically significant decrease in light intensity of the images. 5) Create the thematic map to present the estimation results as geographic information. 6) Disseminate the result map widely and quickly through the WWW.

Sonnblich, Austria) AN - 52249746; 2001-024850 AB - With an elaborate accelerator mass spectrometry (AMS) technique radiocarbon measurements have been performed with aerosol carbon filtered from high alpine snow samples gathered consecutively at the high-altitude research station Sonnblick (3106 m, Eastern Alps, Austria) during a snow storm in April 1997. The concentration of the water-insoluble carbonaceous material in the molten snow was on the average 310 mu g C/L and the total sample amounts for analysis were in the range of 35 mu g to 60 mu g C. Using a special background correction procedure tested on similar amounts of an urban particulate standard sample the accuracy of the corrected and normalized (super 14) C/ (super 12) C isotopic ratios of the snow aerosol samples was in the order of 4% to 14% of the measured ratios. The water-insoluble carbonaceous material of five samples from Mt. Sonnblick exhibited a weighted mean of 74 pMC (percent Modern Carbon) with a range of 64 pMC to 88 pMC. Thus, it appears that about 64% of non-soluble carbon in high alpine snow from Sonnblick was of biogenic origin. The temporal variations of the (super 14) C/ (super 12) C isotopic ratios of the snow aerosol samples were statistically significant, suggesting alterations in the contribution of specific aerosol sources.

The theory is presented and various examples are given of certain combinations of SSC and DSC that test for residual altimetry data errors, mostly of non-gravitational origin, of the order of a few centimeters. There are four types of basic DSCs and 12 independent combinations of them in pairs which have been found useful in the present work. These are defined in terms of the "mean" and "variable" components of a satellite's geopotential orbit error from Rosborough's 1st-order analytical theory. The remaining small errors, after all altimeter data corrections are applied and the relative offset of coordinate frames between altimetry missions removed, are statistically evaluated by means of the Student distribution. The remaining signal of "non-gravitational" origin can in some cases be attributed to the main ocean currents which were not accounted for among the media or sea-surface corrections. In future, they may be resolved by a long-term global circulation model. Experience with two current models, neither of which are found either to cover the most critical missions (Geosat & TOPEX/Poseidon) or to have the accuracy and resolution necessary to account for the strongest anomalies found across them, is described. In other cases, the residual signal is due to errors in tides, altimeter delay corrections or El Nino. (Various examples of these are also presented.) Tests of the combinations of the JGM 3-based DSC residuals show that overall the long-term data now available are well suited for a gravity field inversion refining JGM 3 for low- and resonant-order geopotential harmonics whose signatures are clearly seen in the basic DSC and SSC sets.

Hydrologic studies of nested watersheds are rare in the circumpolar arctic. Presented here is a comparison of the variability of important runoff-related processes from the headwater foothills to the low gradient, wetland dominated coastal area. Watersheds studied include Imnavait Creek, Upper Kuparuk River and finally the entire Kuparuk River. Also, runoff data from the low gradient Putuligayuk River, measured earlier (1970-1986), is included. Generally, rainfall constitutes 53 to 67% of the annual precipitation. Most runoff is generated from the foothills; runoff is normally only generated from the coastal plain during snowmelt. Surface storage is an important process on the coastal plain where vertical processes (precipitation and evapotranspiration) are dominant during the summer. Continuous permafrost produces high soil moisture levels except where there are relatively steep slopes with gravity-induced drainage. Snowmelt results in a nearly saturated active layer with summer moisture levels closely allied with summer precipitation. High runoff ratios prevail during snowmelt and rainfall, except for the summer rainfall-generated runoff of the low gradient Putuligayuk River.

Pesticide concentrations closely followed the stream hydrograph during the spring and summer. The highest water concentrations measured during the study exceeded freshwater aquatic life guidelines for several compounds including atrazine, chlorothalonil, chlorpyrifos, cyanazine, 2,4-D, diazinon, malathion, metolachlor, simazine, and trifluralin. Bulk atmospheric deposition samples indicate that the atmosphere continues to be an important source of pesticides to the watershed. Sediment levels of current-use pesticides indicated that this medium could be a sink for pesticides in streams and a source of contamination to river estuaries downstream.

However, since these SAR instruments are both single frequency, single polarization, it is often difficult to unambiguously analyze the myriad features in an image without consulting other types of data. A near real-time demonstration of SAR applications in Alaska, the Alaska SAR Demonstration, provides products to users who have minimal acquaintance with SAR imagery. To aid them in interpreting the SAR signatures, an analysis system called the World Wide Web Interactive Processing Environment (WIPE) is used to provide a capability for analyzing SAR imagery together with other satellite, in situ and model data. This system is then used to interpret SAR signatures of oceanic and atmospheric fronts, storms, upwelling, oil slicks, etc. This paper describes the AKDEMO and its products as well as the WIPE system used to display and analyze the SAR imagery. An example illustrating the synergy of using visible satellite radiometer data along with SAR imagery for ocean feature analysis is then presented.

Samples of zooplankton, macrozooplankton, amphipods, as well as size or age classes of sculpins and salmonids were taken from Lake Baikal during August-September 1993 and from Lake Superior during May-July, 1994. Samples were analyzed by gas chromatography with electron-capture and mass-spectrometry detection for 74 PCB congeners, chlordanes, HCHs, HCB, DDT compounds, and toxaphene. The lipid content and stable nitrogen isotopes of the samples were also measured. Stable nitrogen isotopes were measured to provide information on an organism's trophic level. The HCB, HCHs, Sigma chlordanes, Sigma PCBs, and toxaphene concentrations were generally lower in the samples from Lake Baikal than from Lake Superior. DDT compounds were generally higher in concentration in the samples from Lake Baikal than from Lake Superior. In both lakes, wet weight POP concentrations in the food web were mainly affected by an increase in lipid with trophic position-more so than trophic position alone. The ratios of log predator/prey for individual PCB congeners were not related to log K (sub ow) in the Lake Superior food web, which conflicted with the results of laboratory feeding studies, suggesting that uptake rates of high log K (sub ow) POPs from food are offset by re-equilibration with water. The reverse, however, was true of Lake Baikal, where there was a good relationship between log predator/prey POPs concentration and log K (sub ow) .

One input to GOA sediments is particulate coal, eroded from coal-bearing formations (e.g., the Eocene Kulthieth Formation) by the Bering and Malaspina Glaciers. Coal particles have recently been observed in strand lines on a GOA beach at Katalla (near the Bering Glacier), but neither the source nor the geochemical significance of this occurrence has been evaluated. These issues merit consideration, as particulate coal accumulation in sediments can confound estimates of productivity that are based on measurements of total organic carbon (TOC). Furthermore, organic contaminants (e.g., polycyclic aromatic hydrocarbons) associated with coal can obscure environmental assessments. The objectives of this study were to identify sources of particulate coal found in GOA sediments and to evaluate the effects of such input on sediment geochemistry. A heavy liquid separation technique was developed to isolate coal particles from bulk sediments. Vitrinite reflectance (VR) data were used to identify macerals and characterize the extent of maturity of the isolated particles. Based on VR data the Katalla beach samples are classified as low rank anthracite (Ro approximately 2.5%), as are the coals from local coal fields. Coal has also been isolated from benthic sediments in the GOA and Prince William Sound; longshore transport may be an important mechanism in dispersing particulate coal. Preliminary data indicate that coal particles can account for greater than 20% of the TOC in benthic GOA sediments, and as much as 50% of the TOC in riparian sediment adjacent to the GOA.

During warm-tropical El Nino and cool-tropical La Nina episodes, streamflows are affected throughout the Americas and Australia, in northern Europe, and in parts of Africa and Asia. In North and South America, correlations between peak-flow season streamflows and seasonal Southern Oscillation Indices (SOIs) show considerable persistence. In South America, correlations between flows in other seasons with December-February SOIs also are notably persistent, whereas, in North America, correlations are smaller when other, non-peak season time periods are considered. At least two modes of streamflow response to ENSO are present in the Western Hemisphere. When interannual North and South American streamflow variations are analyzed together in a single principal components analysis, two of the leading components are found to be associated with ENSO climate variability. The more powerful of these modes corresponds mostly to ENSO responses by the rivers of tropical South America east of the Andes, along with rivers in southern South America and the southwestern United States, with Brazil experiencing less runoff during El Ninos and the other regions experiencing more runoff. This streamflow mode is correlated globally with ENSO-like sea surface temperature (SST) patterns on both interannual and interdecadal timescales; indeed, the tropical South American rivers east of the Andes are coherent with SOI on virtually all historical timescales. The second ENSO-related streamflow mode characterizes other parts of extratropical streamflow variation, emphasizing the north-south differences in streamflows in North America during ENSO extremes and (less robustly) streamflow variations along the central Andes. The relation of this extratropical streamflow mode to ENSO seems to be mostly from scattered interannual timescales, and, overall, its decadal variations follow North Atlantic SSTs. On decadal time scales, the most remarkable variation identified in the Western Hemisphere ENSO-streamflow correlations or teleconnections is a decades-long contrast between the teleconnections of recent decades and teleconnections from about the 1920s into the 1950s. Correlations between streamflows and SOI, Nino-3 SSTs, and even global SSTs nearly vanished in many regions of North and South America during the earlier period. The change appears to have been associated with weakening of ENSO and, possibly, a weakening of connections between the atmospheric and oceanic components of ENSO during the earlier period. The development of two ENSO-related principal components of North and South American streamflow, rather than one, may be an artifact of the differences in decadal scale responses of streamflows in the tropics and extratropics to multiscale ENSO forcings.

Unanswered questions remain, however, and their resolution is central to assessing and fully harvesting the atmospheric predictability inherent in the ENSO phenomenon. Among these questions are the sensitivity of the extratropical response to the annual cycle, the nonlinearity of that response with respect to the sign and amplitude of tropical sea surface temperature (SST) anomalies, and the further sensitivity of the response to differences in the SST anomaly patterns that distinguish one El Nino event from another. Beyond these problems of seasonal to interannual variability, it is also important to understand multidecadal-scale variations of ENSO impacts and to assess their origins. Our inquiry into these problems begins with an analysis of the last half-century of observed circulation data, using the upper tropospheric flow patterns to identify the teleconnections that link the tropics and the extratropics during ENSO. Several new aspects of the observed teleconnection behavior are highlighted; however, the data archive is undoubtedly too brief to offer a complete or even an accurate sample of the spectrum of atmospheric sensitivity to ENSO. Nor is it likely that the full spectrum of tropical SST variations themselves have been sampled by observations. We thus provide additional analyses based on the results of atmospheric general circulation model experiments that have been forced either with the recent 50-year record of observed global SST variations or with idealized SST anomalies. These analyses, when combined with the observational analyses, yield a richer image of teleconnections related to ENSO and also provide a means to quantify the potential for predicting such patterns.

The sediment core contains hundreds of light-colored clastic laminae deposited during alluviation events. A digital linescan camera was used to quantify the distribution of light-colored laminae in the core. The correlation of light layers from the past 200 years of record to known severe ENSO events recorded in instrumental and historical records, and the presence of variance of the laminae in the 2-7 yr ENSO band, indicates that the lake records an ENSO signal. Spectral analysis of 11,450 yrs of linescan data using wavelet analysis, the multi-taper method, and the Blackman-Tukey method, reveals significant variance at millennial, centennial, decadal, and sub-decadal time scales. Variance in the millennial band is centered on a period of 2000 years and is significant throughout the Holocene, while variance in the centennial band is centered on a period of approximately 600 years and is significant only during the most recent 5000 years of the record. Variance in the decadal band is centered on periods of approximately 50 and approximately 20, years while variance in the sub-decadal or ENSO band is spread over a range of frequencies. The variance in the decadal and ENSO band is significant throughout the Holocene, but it is predominantly found in the past 7,000 yrs of the record.

An event at approximately 136 Ma is marked by the onset of sea floor spreading between Greater India and Australia. At about this time long-lived subduction east of Australia ceased, probably due to subduction of the Phoenix-Pacific spreading ridge, changing this plate boundary to a transform margin. Between 130 and 80 Ma, Australia and East Antarctica moved eastward in the Atlantic-Indian mantle hotspot reference frame. This can be plausibly linked to ridge push from the NW-SE oriented spreading center NW of Australia and to the inferred geometry and continued subduction of the Phoenix plate beneath the West Antarctic margin. A drastic change in spreading direction between the Indian and Australian plates from NE-SW to N-S occurred at about 99 Ma, possibly caused by a change in absolute motion of the Pacific Plate. Chron 27 ( approximately 61 Ma) marks the onset of relative motion between East and West Antarctica, and a change in the relative motion between Australia and Antarctica. It may be linked to the subduction of a segment of the Neo-Tethyan Ridge. Both events caused anomalous subsidence on the Northwest Shelf of Australia. The almost stationary position of Australia w.r.t. the mantle from approximately 80 Ma to approximately 40 Ma may reflect the progressive subduction of the Pacific-Phoenix ridge to the east of New Zealand preceding 80 Ma, resulting in a diminished trench suction force east of Australia. Preliminary reconstructions to close the Pacific-Australian plate circuit based on recently collected geophysical data indicate that a tectonic event at 43 Ma may mark the onset of renewed subduction east of Australia. At the same time spreading in the Wharton Basin between India and Australia ceased, and tectonic reactivation is recorded in the Bass Strait. Excess late Tertiary subsidence on the northwest shelf of >500 m matches the anomalous depth of the Argo abyssal plain ocean floor. This anomalous subsidence may express large-scale intraplate deformation in the Indian Ocean. Asymmetries in oceanic crustal accretion around Australia are caused mainly by hotspot-ridge and coldspot-ridge interaction.

The resultant sense of intraplate stress predicted from the reorganization within the Antarctic plate is consistent with the left-lateral focal mechanism and trend of the fault rupture defined by the March 25, 1998 Antarctic earthquake and its aftershocks. This is the first viable tectonic solution that has been presented for the origin of this earthquake which is the largest (Mw = 8.1) historical recorded intraplate earthquake. In fact we suggest that the fault rupture defines an emergent plate boundary between a new unrecognized St. Vincent plate and the Antarctic plate. Furthermore we suggest that the misfit of the predicted present day NUVEL1 Australia-Antarctica spreading direction with observed transform azimuths and earthquake slip vectors for the easternmost Southeast Indian Ridge can be resolved by the recognition of an additional West Antarctic plate. The new plate geometry that we define implies that there are two unrecognized triple junctions on the Southeast Indian Ridge, approximately 139E and approximately 146E. In this paper we present evidence for the ridge reorganization, its implications and the emergent triple junctions.

Some of these lakes are created when a glacier encroaches on a tributary drainage and blocks the outlet. Runoff then starts to collect above the encroachment until a breach begins to form in the glacial ice and then the water is suddenly released. These jokulhlaup events occur repeatedly at locations where topography and climate permit. Typically the frequency of releases is about once a year. At some locations the subsequent wave released will achieve discharge rates that exceed the median annual maximum and cause flooding. This paper explores the factors necessary for glacier lake formation and the processes responsible for causing a glacier dam to release its water. A survey is also made of the locations where major jokulhlaup events are known to have occurred in the state of Alaska.

This evolution is described from mid-1996 through 1998 using a remarkable data set of 35 meridional conductivity-temperature-depth (CTD)/acoustic Doppler current profiler (ADCP) sections along with buoy data. The sections, nominally from 8 degrees S to 8 degrees N between 165 degrees E and 95 degrees W, were occupied over the course of 27 months. A wide range of current variability was sampled with currents that appeared or disappeared some time during the cycle, including an equatorially trapped eastward surface current, the Equatorial Undercurrent, the northern branch of the South Equatorial Current, and the North Equatorial Countercurrent. Basin-wide, interannual changes in upper ocean and pycnocline zonal transports were as large as 64 + or - 32 X 10 (super 6) m (super 3) s (super -1) . Changes in the salinity structure included a deep and fresh mixed layer in the central equatorial Pacific that built up during the El Nino and was then disrupted by upwelled salty water with the onset of La Nina, a very fresh mixed layer observed in the eastern equatorial Pacific late in the El Nino, and a reduction in the strength of the meridional equatorial salinity gradient within the pycnocline to one third of the usual value during the El Nino. Finally, the zonal transports above the thermocline from 5 degrees S to 5 degrees N were well correlated with the rate of change of warm-water volume west of the individual CTD/ADCP sections.

Presently, positive anomalies ("HotSpots") are determined, at 50 km resolution on a bi-weekly basis, by comparison of the operational (nighttime-only) SST chart with a static satellite-derived (nighttime-only) maximum monthly mean climatology. In 1997 and 1998, HotSpot mapping identified large areas of the global tropics that experienced prolonged warming. The widespread extent, magnitude, and duration of HotSpots in 1998 indicated that SSTs sufficient to induce and prolong coral bleaching were maintained at higher levels and over larger geographic areas than for all prior events since 1982, eclipsing the previous high observed in 1988. Satellite SSTs document a robust warming throughout the tropics (esp. the N. Hemisphere) since the early 1980s. Experimental HotSpot accumulation maps constitute a means to relate the duration and magnitude of HotSpots, in the form of a Degree Heating Weeks (DHWs) Index, to the timing of coral bleaching in the tropical oceans. One DHW is equivalent to one week of SSTs one degree warmer than the expected summer-time maximum. DHWs are being used to determine the amount of accumulated thermal stress, and its residence time, that results in bleaching, recognizing that concurrent factors such as low winds and/or high insolation may amplify the thermal forcing. Coincident with reports of significant bleaching in early 1998, retrospective Eastern Hemisphere DHWs accumulations between February and April 1998 show 4->16 DHWs in the western Pacific and in the equatorial Indian Ocean. Four or more DHWs accounted for mass bleaching in the southern GBR and in widespread areas of the Indian Ocean. A retrospective study of HotSpots for the years 1985-1999 is being undertaken at increased resolution using the NOAA/NASA (JPL) Oceans Pathfinder SST data set (9 km; day- and night-time data) and a new Pathfinder satellite-only MMM climatology (9 km; day + night). NOAA/NESDIS is converting the operational HotSpot mapping to 9 km resolution to match the Pathfinder data set and to establish long term and continuing high-resolution SST time-series for reef studies.

NTIS Prices: PC A15/MF A03 N1 - Last updated - 2011-12-14 ER - TY - JOUR T1 - Free Ion Controls on Zn and Cd Uptake by Phytoplankton in Estuarine and Oceanic Waters AN - 20260708; 8803014 AB - Culture experiments in metal ion buffer systems indicate that zinc and cadmium uptake by marine phytoplankton is controlled by the concentration of free metal ions or that of dissolved inorganic species. Thus, to predict algal uptake of Zn and Cd, one must know the extent of complexation of these metals by natural organic ligands. Furthermore, while zinc uptake is largely unaffected by changes in the free ion concentrations of other metals, that of cadmium is substantially increased by decreasing concentrations of interactive metals, Mn and Zn. For example, Cd uptake by the coastal diatom Thalassiosira pseudonana is inversely related to the free Mn ion concentration within the [Mn super(2+)] range in coastal waters (10 super(-8) to 10 super(-6) M). Based on our laboratory results, Cd accumulation by phytoplankton should be as influenced by changes in Mn and Zn ion concentrations as it is by variations in free Cd. To test these predictions we used radiotracers ( super(109)Cd, super(65)Zn and super(14)C) to measure Cd and Zn uptake rates and carbon fixation rates in natural assemblages of plankton in the Elizabeth River and southern Chesapeake Bay, a contaminated estuarine system possessing a wide range of dissolved and free ion concentrations of Zn, Cd, and Mn. By dividing plankton Zn and Cd uptake rates (in units of nmol/liter/day) by the carbon assimilation rates (mmol/liter/day) we obtained estimates of steady-state Zn:C and 0Cd:C ratios in the plankton. These values could then be related to the free ion concentrations of Cd and Zn measured by differential pulse anodic stripping voltammetry and free ion concentrations of Mn super(2+) estimated from concentrations of dissolved Mn. Free zinc ion concentrations in the lowest salinity estuarine station was 23 nM and decreased to 0.006 nM in the lower estuary due to algal removal of zinc and chelation titration effects. Over this range, estimated Zn:C in the plankton decreased from 95 to 8.6 kmol/mol. Relationships between these Zn:C values and [Zn super(2+)] agree well with those determined in algal cultures grown in metal ion buffer systems. By contrast, free cadmium decreased from 14 to 1.6 nM from the upper to the lower estuary, but estimated Cd:C in the plankton increased from 0.02 to 0.05 nM with this decrease in free Cd. This counter-intuitive result appears to be largely caused by a 1300-fold decrease in dissolved Mn concentration (from 930 to 7 nM), which greatly enhances Cd uptake by algal Mn transport systems, a major pathway for Cd accumulation. The field Cd:C values agreed remarkably well with those measured in cultures of the diatom Thalassiosira pseudonana for similar combinations of controlling metal ions (Cd super(2+), Mn super(2+), and Zn super(2+)).

NOAA recognizes the importance of education, both formal and informal, in ensuring that the results of scientific research on global environmental issues like climate change and ozone depletion are effectively applied to individual and societal decision making. One of the most important responsibilities and greatest challenges to programs like the USGCRP involves the application of research results in the development of a scientifically and environmentally literate citizenry. This Education Resource Guide was developed as part of NOAA's continuing commitment to this great challenge and reflects a belief that improving the human partnership with the natural Earth system is essential to our future. This Resource Guide is intended as an aid to educators who will conduct programs and activities on climate and global change issues for a variety of audiences. In some cases, these individuals will be involved in formal education at the K-12 level. Equally important are those individuals who provide informal educational opportunities to the general public through museums, aquaria, extension programs, and civic public interest groups. This Resource Guide is not intended to be a comprehensive presentation of the issues. Rather, it provides educators with a selected set of currently available materials which help to frame and clarify some of the key issues associated with changes in the global environment. To prepare this Resource Guide, print and media materials on climate and global change issues were gathered from Federal agencies, non-profit and commercial organizations, environmental and educational associations, schools, community groups and international organizations. These materials were then subjected to a set of review criteria including: scientific accuracy and timeliness, consistency with national science education goals and standards, clarity, age appropriateness, and availability. Individual sections of the Resource Guide were reviewed by scientists and program managers in NOAA. The complete Guide was subjected to a review by a selected set of experts active in the field of climate and global change research along with experts in the field of education. Activities included for classroom application were pilot tested with teachers and students. The materials in the Resource Guide are organized by topic for ease in selecting and compiling presentations and duplicating pages for handouts. The topics are: Natural Climate Variability, Greenhouse Effect, Sea-Level Rise, Ozone Depletion, Ecosystem Response, and Decision-Making Under Scientific Uncertainty. Within each topic, fact sheets, articles, learning activities, full color overhead transparencies and duplicate slides are included. The fact sheets display short summaries of current information and data on each topic. The fact sheets are part of a series produced by the Information Unit on Climate Change sponsored by the United Nations Environment Programme and the World Meteorological Organization. They are also available in Spanish, French, Chinese, Urdu, and Japanese. Annotated bibliography along with information for acquiring additional resources, is included. Where possible, addresses, phone numbers, contact persons, and price information are noted.

AN - 19932255; 5510695 AB - This working paper discusses the methodology and assumptions used to develop the recently released projections of the population of the United States from 1999 to 2100. The new series includes projections of the population by single year of age, sex, race, Hispanic origin, and nativity. While the basic methodology used to produce these projections is the same as in earlier Census Bureau national population projections, there have been changes, in both the time horizon and reference dates of the projections, as well as in the specific methods used to estimate population change. The extension of the series to 2100 carries the projections 20 years further into the future than any series previously issued by the Census Bureau. For the first time, projection results include a break on nativity, defined dichotomously by the presence or absence of U.S. citizenship at birth, as well as its cross-classification with other variables. Also new with this series is the projection to quarterly reference dates, allowing users to view the national population seasonally, or simply to select annual reference dates other than July 1. In addition, international migration in the new series is allowed to vary over time, remaining somewhat lower than the constant value in the previous series for the first two decades of the century, but reaching considerably higher levels than in the previous one after 2020. Fertility rates in both models are allowed to change very little over time. However, fertility rates by race and Hispanic origin are allowed to converge in the new middle series, whereas in the previous middle series they remained constant within race and origin category. Finally, the new mortality assumptions show more improvement in life expectancy for all racial and Hispanic origin groups, except the non-Hispanic White population, than did the assumptions of the previous projection series.

Assembled an international team of marine biologists and physical oceanographers who collectively achieved a consensus on the structure and function of a PICES CCCC prototype lower trophic level ecosystem model for the North Pacific Ocean, and named it "NEMURO"; 2. Developed executable computer simulation models and preliminary outputs. Models developed included: a) NEMURO/FORTRAN Box Model b) NEMURO/1-D Yamanaka Model c) NEMURO/1-D Kishi Model d) NEMURO/MATLAB Box Model; 3. Constructed physical forcing data files and parameter sets for three locations in the North Pacific, station A7 on the A-line off southeast of Hokkaido (41.5 degree N, 145.5 degree E), Ocean Station P (50 degree N, 145 degree W), and the Eastern Bering Sea (57.5 degree N, 175 degree W); 4. Through an extensive dialog between modelers and plankton biologists, conducted a comprehensive review of NEMURO process equations and their parameter values for the three distinct geographic regions; 5. Developed post-processing software to analyze model output in tabular and graphic formats; 6. Carefully considered the benefit including a microbial food web loop in NEMURO and designed a preliminary strategy for conducting comparative model experiments; 7. Identified leaders and members of model experiment teams, a subgroup of the Model Task Team members and meeting participants, who will be active in conducting future model experiments; 8. Initiated development of comparison protocols; 9. Made recommendations for future lower trophic level modeling activities.

Held in La Jolla, California on June 14-16, 1999 AN - 19722202; 8932355 AB - With the International Whaling Commissions (IWCs) moratorium on commercial whaling in effect for more than a decade, several research teams have sampled cetacean products in Asian markets and restaurants, paticularly in Japan and Republic of Korea (South Korea), and used molecular genetic techniques to identify which species and stocks are represented. This forensic use of moleculer techniques to identify which species and stocks are represented. This forensic use of molecular techniques to identify wildlife products in the marketplace is of practical interest to the IWC as it develops a Revised Management Scheme (RMS) to regulate any future whaling, and to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), which is responsible for regulating the international trade in whale products.

The manual contains many of the most common algal species found in crop/stomach samples taken from Hawaiian green turtles. During this study, which began in 1976, we have documented over 275 species of Chlorophyta (green algae), Anthophyta (sea grass), Phaeophyta (brown algae), Rhodophyta (red algae), and Cyanophyta (blue-green algae or blue-green bacteria) in or on green turtles. Green turtles are the most common sea turtle present in Hawaii and are primarily herbivorous, feeding on a variety of marine algae, a single sea grass, invertebrate animals, plus a few freshwater species. This manual aims to begin with the most common green turtle food species and then to expand this effort at a later time to include the less common algae, animals, and incidental items found in gut samples taken over the past 20 years.

The MLD calculated from the individual profiles are averaged with climatological months and 1 degree by 1 degree boxes. This approach yields mean MLD values as well as standards deviations and number of observations. Comparison of the MD computed from the individual profiles of temperatue and density versus the MLD computed from the climatological profiles of temperature and density shows quantitative differences in dynamically active areas of the world ocean such as Kuroshio and Gulf Stream extensions, Labrador Current, Alaska Current and Oyashio Current.

Demographic data collected for the add-on survey were used to develop age, gender, and ethnicity profiles of resident marine recreational fishing participants for each coastal state within the region. These data were also used to develop population cohort participation rates that were combined with U.S. Census Bureau population projections to provide forecasts of marine recreational fishing participation for the period 2000 to 2025. Forecasts were developed for resident participation in each coastal state and for the region. These forecasts are comparable to forecasts developed for the Northeast region by Thunberg et al., 1999 and for the Southeast region (Milon, 2000).

The first mooring was deployed near the Main Vent field on Endeavour Ridge (On-axis site, 47\deg 57.0'N and 129\deg 05.7'W), the second, 3 km west of the On-Axis site (West site), and the third, 43 km northeast of the On-Axis site (East or reference site). Ascending and descending particles were collected near 1600 m and 2000 m depths, within and well above the top of typical laterally advecting hydrothermal plumes in the area. The elemental composition of splits of these samples were analyzed by XRF. Particle composition was used to evaluate origin: biogenic rich material is indicated by elevated Ca or Si, hydrothermal material by elevated Fe, Mn and Cu and lithogenic material by elevated Ti. Fe of hydrothermal origin is a measurable component of the ascending particles at our site nearest the Main Vent field. Monthly variability in both the ascending and descending particle composition and flux is interpreted to be linked to variations in lateral transport of hydrothermal constituents and to seasonal draw down of hydrothermal plume particles by biogenic material from the surface ocean. These results suggest that seasonal productivity and particle export from the surface ocean can modulate the hydrothermal flux of elements to waters above, and sediments below. Baker, E. T. and H. B.

But, when density is computed from objectively analyzed climatologies on isobaric surfaces, vertical instabilities can result. This is the result of two factors: 1) Temperature measurements are not always associated with a salinity measurement. For example, an XBT only measures temperature. The salinity conditions associated with a temperature from the XBT are not represented. 2) The objective analysis technique interpolates and smooths on isobaric surfaces. The temperature and salinity are analyzed independently. Furthermore, each standard depth is analyzed independent of all other depths. The results for temperature and salinity may lead to instances of unrealistic vertical profiles of the calculated local potential density. To fix this, we used a technique based on local linear density trend. When a local potential density instability is detected, the trend of density with respects to temperature (using a constant salinity) in the surrounding depths is calculated. Likewise, the local trend of density with respects to salinity is calculated. The original temperature and/or salinity values are adjusted minimally to achieve stability while preserving the local linear density trend. This technique results in temperature and salinity climatologies which are stable with respects to local potential density. It also results in a more realistic climatology in data-scarce ocean areas, as the stabilization technique eliminates some unrealistic features in the temperature and salinity fields.

However the impacts of climate change on seasonal scales may be more critical to marine ecosystem dynamics (e.g. timing of spring bloom, migration, and spawning). Non-stationary seasonal cycles for time series of atmospheric and oceanic variables affecting the northeast Pacific (NEP) are modeled using state- space statistical methods. This analysis reveals significant variability in the phase and amplitude of the seasonal cycles of key physical forcing mechanisms (e.g. wind stress) in the NEP and globally, associated with climate change. We will describe the important shifts in seasonal behavior on interannual to decadal time scales, and discuss their implications for NEP ecosystems. JF - [np]. 24-28 Jan 2000.

We employ the Geophysical Fluid Dynamics Laboratory global chemical transport model \(GFDL GCTM\) to investigate these questions employing present and future estimates of Asian emissions. Results from simulations of nitrogen oxides \(NOx\), carbon monoxide \(CO\), and ozone \(O3\) employing present \(1990\) sources and detailed estimates of future emissions from Asia will be presented. Specific issues include quantifying the export of NOx, CO, and O3 from Asia's polluted BL out over the North Pacific, investigating the integrated impact of this export on the balance of ozone production and destruction over the North Pacific and its impact on the nitrate levels in the North Pacific, and examining the impact of episodic transport events relative to mean concentrations and deposition.

N1 - Last updated - 2016-12-21 ER - TY - BOOK T1 - The Significance of Seasonal Wind Patterns in Forcing Biological Processes in the Eastern Bering Sea AN - 19607302; 7323567 AB - During 1997, 1998, and 1999, we observed how variations in the winter, spring and summer winds resulted in dramatic variability in the structure and function of the southeastern Bering Sea shelf ecosystem. Winter ice cover reflects the duration, strength and direction of winter winds. In 1997, moderate winter winds resulted in average ice cover that persisted into April; in 1998 weak winds with a more southwesterly component resulted in minimal ice cover of brief duration. In 1999, a less extensive ice cover than in 1997 remained over the southeastern shelf into May. The transition (timing and duration) from winter to spring/summer conditions determines biological responses. An ice- related bloom occurred in April 1997, when ice was present with adequate light available to support photosynthesis, whereas the early departure of ice from the southeastern shelf in 1998 was associated with May/June bloom. The timing, frequency and strength of spring storms dictated whether there was a strong spring bloom (1997) or prolonged production (1998). In addition, the strength and stability of the inner front was modified by the prevailing wind conditions. Weak winds in spring and summer 1997 resulted in a broad, diffuse front with nutrients drawn down to a depth of 60m and few nutrients entered the upper mixed layer. In contrast, the strong storms of spring and the lack of an ice-edge bloom in 1998 resulted in a slow draw-down of nutrients. During 1999, the stability of the front permitted events of vertical mixing/upwelling to supply nutrients to the upper mixed layer throughout summer, thus supporting prolonged production. Interannual variation in the shelf production regimes was reflected in the body condition of migrant short-tailed shearwaters ({\it Puffinus tenuirostris}), which starved in fall 1997, were emaciated, but survived in fall 1998, and were of healthy body mass in 1999. Our observations demonstrate some of the mechanisms whereby climate change may cause rapid and extreme changes in a shelf ecosystem. JF - [np]. 24-28 Jan 2000.

A Report of the Turtle Expert Working Group AN - 19465413; 8016521 AB - The Kemp's ridley population appears to be in the early stage of exponential expansion. While the number of females nesting annually is estimated to be orders of magnitude less than historical levels, the mean rate of increase in the annual number of nests has accelerated over the period 1987 to 1999. If assumptions that estimated age to sexual maturity and age specific mortality rates are correct, preliminary analyses suggest that the intermediate recovery goal of 10,000 nesting females by the year 2020 is achievable. It appears that the South Florida loggerhead subpopulation, which is the largest in terms of nesting females, is stable or may be increasing; the status of the Florida Panhandle and Yucatan subpopulations is unknown. Current trends for the Northern subpopulation indicate this subpopulation has declined since the 1970's and may have stabilized, but it is unlikely that the recovery goals for this subpopulation will be achieved.

These observations are important not only for improved seasonal and interannual climate forecasts and coastal marine forecasts but also for advancing our understanding of the oceanic circulation and its variability and assessing its impact on living marine resources. At the National Ocean Conference in June 1998, this importance was reflected in the President's commitment to expand our ocean observing capabilities. A subsequent Congressional hearing focused on this same topic and resulted in a request from Congressmen Saxton and Weldon to the U.S. National Ocean Research Leadership Council to prepare a plan to achieve a truly integrated ocean observing system. This request resulted in a first report prepared under the leadership of Dr. Worth Nowlin (Texas A&M) and Tom Malone (University of Maryland) ("Toward a U.S. Plan for an Integrated, Sustained Ocean Observing System" available at the site below). The next step in the development of a plan for such a system is being prepared under the chairmanship of Robert Frosch (Harvard University), a document that will include specific recommendations and priorities as well as options for management. As the nation's civil operational ocean agency, NOAA is focusing on the unique contribution that it can make, and has offered to lead, in partnership with the Navy, NSF, and other Federal agencies the planning and development of a national ocean observing system which can be sustained for the long term. Just as it made the ENSO observing system operational, NOAA intends to implement additional operational systems. Initial NOAA implementation planning is focusing on sustained observations for climate and marine forecasting; planning for coastal and fisheries services will follow. Efforts on the part of NOAA, Navy, NSF, and other Federal agencies represent a U.S. contribution to the international Global Ocean Observing System and the Global Climate Observing System. Success will be critically dependent on fostering effective international collaboration. UR: http://core.cast.msstate.edu/NOPPobsplan.html JF - [np]. 24-28 Jan 2000.

This interdisciplinary program will be designed to improve understanding, conservation, and management of the living marine resources of the northern Gulf of Alaska. Minimum annual cost would be $5-6 million dollars, inclusive of all aspects of the program. The GEM Program would aim to: (1) track lingering oil spill injury (e.g., oil exposure in sea otters) and apply what is learned to injury assessment and response to future oil spills (e.g., NRDN /contingency planning); (2) identify and understand annual and long-term changes in the marine ecosystem, distinguishing natural variability from human influences (e.g., wide swings in salmon, marine mammal, and seabird populations); (3) develop new fish and wildlife management tools (e.g., genetic stock identification in commercially important fish species); (4) provide integrated and synthesized information on the status, trends and health of fisheries and other marine resources, including water quality and contaminants in fish and wildlife consumed by people (e.g., produce annual 'state of the gulf' report, with periodic updates as new information becomes available); (5) support the identification and protection of important marine habitats (e.g., assist with siting of marine industrial and mariculture facilities; establish protected reserves); and (6) foster efficiency through interagency coordination and scientific leadership and the leveraging of GEM funds to guide uses of funds from other sources (e.g., the NOAA/NSF GLOBEC program on climate change and the oceans).

Computer visualization is used to compare model results to the evidence of cross-isobath transport suggested in satellite imagery. Model results showed that circulation in Lake Michigan is highly episodic since it is almost entirely wind-driven in early spring. The characteristic wind-driven circulation pattern in the lake consists of two counter-rotating gyres, a counterclockwise-rotating gyre to the right of the wind, and a clockwise-rotating gyre to the left. The gyres are separated by a convergence zone along the downwind shore with resulting offshore flow and a divergence zone along the upwind shore with onshore flow. This two-gyre circulation pattern with offshore flow was very clearly seen during a northerly wind event in March 1998 in southern Lake Michigan. The strongest sediment resuspension occurred in the southern lake and the shallow waters along the coastline. This is because of the larger waves in southern Lake Michigan due to the dominant northerly wind in this early spring period. The two most significant sediment resuspension events were detected in the model results during the two storm events. Although results from the sediment transport model agree qualitatively with satellite imagery, they fail to simulate the initial eddy-like structure of the plume. Visualization is shown to be an effective tool for interpreting the complex turbidity patterns in the satellite imagery of the turbidity plume. Copyright 2000 Academic Press.

Short-beaked common dolphins (Delphinus delphis) occurred year-round and were the most abundant marine mammal in the study area (N = 26,238, CV = 0.30). Common dolphin abundance was 2.5 times greater during the warm-water months of May through October (N = 3 8,851, CV = 0.39) than during the cold-water months of November through April (N = 14,834, CV = 0.37). Dall's porpoise (Phocoenoides dalli), northern right whale dolphins (Lissodelphis borealis) and Pacific white-sided dolphins (Lagenorhynchus obliquidens) were present only during the cold-water months of November-April. Of these cold-water species, Pacific white-sided dolphins were the most abundant (N = 1,649, CV = 0.44), followed by northern right whale dolphins (N = 754, CV = 0.40) and Dall's porpoise (N = 370, CV = 0.62). Risso's dolphin abundance was three times higher during cold-water months (N = 1,500, CV = 0.40) than during warm-water months (N = 513, CV = 0.56). Bottlenose dolphins were the least abundant dolphin (N = 207, CV = 0.50) and were found year-round, primarily in association with Risso's dolphins. Gray whales (Eschrichtius robustus) were the most abundant whale during the months of January through April, when a daily average of 424 whales (CV = 0.29) were within the study area during the peak of migration. Numbers of migrating gray whales found in these waters suggests that a significant fraction of the entire population traverses this area during both southbound and northbound migrations. Fin whales (Balaenoptera physalus) were present year-round and were the next most abundant whale species (N = 48, CV = 0.26). Blue whales (Balaenoptera musculus) were present primarily during the late spring and summer (N = 40, CV = 0.39), with one exception of a southbound whale seen in November. Humpback whales were encountered only twice, in April of 1998 and 1999 (N = 12, CV = 0.46). Cuvier's beaked whales (Ziphius cavirostris) were encountered four times during the cold-water months of November through April (N = 153, CV = 0.52). California sea lions (Zalophus californianus) were the most abundant pinniped in the study area. JF - Administrative Report.

Samples of zooplankton, macrozooplankton, amphipods, as well as size or age classes of sculpins and salmonids were taken from Lake Baikal during August-September 1993 and from Lake Superior during May-July, 1994. Samples were analyzed by gas chromatography with electron-capture and mass-spectrometry detection for 74 PCB congeners, chlordanes, HCHs, HCB, DDT compounds, and toxaphene. The lipid content and stable nitrogen isotopes of the samples were also measured. Stable nitrogen isotopes were measured to provide information on an organism's trophic level. The HCB, HCHs, capital sigma -chlordanes, capital sigma -PCBs, and toxaphene concentrations were generally lower in the samples from Lake Baikal than from Lake Superior. DDT compounds were generally higher in concentration in the samples from Lake Baikal than from Lake Superior. In both lakes, wet weight POP concentrations in the food web were mainly affected by an increase in lipid with trophic position-more so than trophic position alone. The ratios of log predator/prey for individual PCB congeners were not related to log K sub(ow) in the Lake Superior food web, which conflicted with the results of laboratory feeding studies, suggesting that uptake rates of high log K sub(ow) POPs from food are offset by re-equilibration with water. The reverse, however, was true of Lake Baikal, where there was a good relationship between log predator/prey POPs concentration and log K sub(ow). This is likely due to temporal variability in the concentrations of POPs in the water column arising from local and/or regional POP sources.

In this paper, the seasonal cycle of latent, sensible, and total heat flux from the surface of the Great Lakes is estimated. Lake surface temperatures derived from the NOAA/AVHRR satellite, along with meteorological data from surface station observations are incorporated in order to estimate spatial distributions of fluxes. Several well-known features are evident. Among these are the very high outgoing fluxes of latent and sensible heat during the late fall and early winter, which drive strong cooling of the lake surface and consequent convective mixing within the lake column. Another is greater seasonal variation of surface temperature and fluxes in shallower waters than in deeper waters. Due to strong static stability of the overlying atmospheric boundary layer during the spring, both the magnitude and the spatial variations of latent and sensible heat fluxes are small during the spring and, to a lesser degree, during the summer. The annual cycles of latent and sensible heat flux over the Great Lakes are roughly opposite in phase to the same fluxes over land, indicating a large exchange of energy via atmospheric advection between the lake and land surfaces. A major weakness of the method used here is that heat fluxes are calculated on the basis of an ice-free surface, making the derived fluxes for January through March roughly estimated.

In this study, the authors present the signatures of ENSO impacts on the surface - atmosphere system, as detected in satellite products that are routinely derived at NOAA from measurements by a single instrument on board NOAA polar - orbiting satellites - the Advanced Very High Resolution Radiometer (AVHRR). The Indonesian archipelago was selected to demonstrate how AVHRR products can be synergistically used to monitor interannual variability, such as caused by ENSO, on regional and global scales. The authors examined month - to - month changes in surface - atmosphere conditions over the region during July 1997 - June 1998. The major ENSO impact over the Indonesian archipelago was a prolonged dry period with anomalously low amounts of cloud, precipitation, and water vapor. The net effect of these changes was a significant increase in the absorbed shortwave and outgoing longwave radiation fluxes. ENSO - induced drought coincided with the slash - and - burn agricultural season, which resulted in persistent fires and smoke from biomass burning, covering larger areas, producing more smoke, remaining longer than during most dry seasons, and causing health hazards for millions of people in Southeast Asia. Analysis of the impact of fires on cloud microphysics confirms earlier suggestions that the effective cloud droplet size decreases due to smoke aerosols and cloud reflectivity increases due to higher concentration of small droplets. Analysis of areas with active fires showed a decrease in both surface albedo and fractional green vegetation as a result of intensive burning.

The observations show that bottom resuspension occurred several times during the unstratified period. The resuspension is the result of the interaction between high bottom current velocities and surface waves generated by strong winds. Transport during the storms was almost entirely alongshore, although some offshore transport of material occurred. Calculations show that suspended material could have been transported eastward several hundred km during the unstratified period.

Freshwater floods caused more than one-half of the 600 U.S. deaths directly associated with tropical cyclones or their remnants during that 30-year period. More than three-quarters of the victims under age 13 died in rain-induced floods. Most fatalities occurred in inland counties. Storm surge losses were significantly (but perhaps only temporarily) less than in previous periods of comparable length. This paper presents a statistical summary of the casualties, explores reasons for the losses, and reviews efforts to mitigate the threats.

This snow product is subjective, and its preparation requires a substantial daily human effort. The primary objective of the current study was to develop an automated system that could provide NOAA analysts with a first-guess snow cover map and thus to reduce the human labor in the daily snow cover analysis. The proposed system uses a combination of observations in the visible, midinfrared, and infrared made by the Imager instrument aboard Geostationary Operational Environmental Satellites (GOES) and microwave observations of the Special Sensor Microwave Imager (SSM/I) aboard the polar-orbiting Defense Meteorological Satellite Program platform. The devised technique was applied to satellite data for mapping snow cover for the North American continent during the winter season of 1998/99. To assess the system performance, the automatically produced snow maps were compared with the NOAA interactive operational product and were validated against in situ land surface observations. Validation tests revealed that in 85% of cases the automated snow maps fit exactly the ground snow cover reports. Snow identification with the combination of GOES and SSM/I observations was found to be more efficient than the one based solely on satellite microwave data. Comparisons between the automated maps and the NOAA operational product have shown their good agreement in the distribution of snow cover and its area coverage. The accuracy of the automated product was found to be similar to and sometimes higher than the accuracy of the operational snow cover maps manually produced at NOAA.

High survival after >200 days at cold temperatures (<3.0 degree C) indicated extended tolerance of extreme cold, as long as sufficient body size and condition are attained during the summer growth period. Analysis of body constituents demonstrated a substantial increase in tissue water and depletion of lipid during starvation. Survivors had significantly higher lipid stores than mortalities, and larger fish had higher levels of lipid than smaller fish among experimental survivors, laboratory fish that were never starved, and wild fish. Fish returned to warm temperatures and high rations following 205 days of food deprivation displayed nearly complete recovery, with rapid increases in length, weight, and condition and minimal mortality (6.8%) during the subsequent 3 months. Age-0 walleye pollock collected in September in the Bering Sea were substantially smaller and generally had lower lipid levels than fish used in laboratory starvation experiments, suggesting they are susceptible to size- and condition-dependent mortality during the winter. The results are interpreted with respect to field distributions of age-0 walleye pollock, overwinter survival, and synergistic effects of food and temperature under varying models of climate change.

The authors have identified three areas where LC effects may be important in spill behavior. These three areas are spreading, dispersion, and transport. LC will cause the slick to break into windrows when the wind-row formation velocity is comparable to Fay and other spreading forces. Oil dispersion is likely to be enhanced, with droplets carried to greater depth and distributed non-uniformly. Transport velocities for different parts of the slick will vary because of LC, a phenomenon that also occurs because of other factors.

Data were collected to monitor mysids relative to ongoing ecological changes in Lake Michigan and as a comparison to studies from the 1970s and 1980s. Mean densities of M. relicta during May through September each year were higher offshore (210/m super(2) to 373/m super(2)) compared to nearshore (41/m super(2) to 168/m super(2)). Growth rates ranged between 0.026 to 0.041 mm/day and did not differ between stations or with age. Juvenile mysids (< 10 mm) dominated the population, and accounted for 30 to 90% of the catch. The size distribution of M. relicta suggested that reproduction occurred year-round with the most consistent influxes of juveniles in the spring (April through June) each year; winter (February and March) and summer (July through September) influxes of juveniles did not occur consistently each year. Mean length of females with broods differed between nearshore (14 mm) and offshore (16 mm). Brood size and the proportion of females with broods did not differ between stations. Abundance estimates were equal or higher and life history characteristics were similar to reported data from the 1970s and 1980s. However, ongoing declines in the benthic macroinvertebrate Diporeia may result in higher fish predation pressure on M. relicta in the near future.

A total of thirty-six participants were included in the exercise, including NOAA, USEPA, state, Australian, Canadian, Mexican and Argentinean laboratories. Two samples were sent by NRC to each participant, a marine sediment from the Beaufort Sea and a freeze-dried mussel (Mytillus edulis) tissue. Laboratories were also asked to analyze two certified reference materials (CRMs) CRM 2976 and MESS-2. The elements to be determined were Al, Cr, Fe, Ni, Cu, Zn, As, Se, Ag, Cd, Sn, Hg, and Pb for both matrices, plus Be, Si, Mn, Sb, and TI for the sediments. An accepted mean and confidence interval was calculated for each analyte in the two unknown samples, laboratory biases were identified and an overall rating of superior, good, fair, or others were assigned to each laboratory.

The levels of PCBs found in marine mammals are often several orders of magnitude greater than the levels found in humans and other terrestrial mammals. These finding are cause for concern, given the current body of experimental and epidemiological evidence that links PCBs to deleterious effects on reproduction and immune system function. Compounding this concern are reports of recent disease outbreaks that have critically reduced many populations of marine mammals and are suspected to have been caused, at least in part, by the high concentrations of pollutants found in the tissues of the stranded animals. Determination of the potential risks associated with exposure to persistent organochlorine pollutants is essential for the conservation and management of marine mammal species. This is a complex task, requiring the integration of models of population dynamics with estimates of exposure and associated effects.

Both datasets blend satellite and gauge estimates of precipitation. And while the latter has its heritage in the GPCP, different analysis procedures and some additional types of input data used by CMAP yielded different values. This study used the error characteristics of the data to assess the significance of the observed differences. Despite good spatial and temporal correlations between the two fields some of the observed differences were significant at the 95% level. These were traced to the use of some different input data such as the use by CMAP of atoll gauges in the tropical Pacific and gauges uncorrected for wetting evaporation and aerodynamic effects. The former impacts the tropical ocean rain amounts and the latter is particularly noticeable in the Northern Hemisphere land areas. Also, the application of these datasets to the validation of atmospheric general circulation models is discussed.

The added dynamic range allows the profiler to record radar reflectivity measurements in moderate to heavy precipitation that otherwise would not have been possible with this system because of receiver saturation. The radar hardware, signal processor, and operating software are based on existing S-band and UHF profiler technology. Results from a side-by-side comparison with a calibrated Ka-band radar are used to determine the calibration and sensitivity of the S-band profiler. In a typical cloud profiling mode of operation, the sensitivity is - 14 dBZ at 10 km. Examples taken from a recent field campaign are shown to illustrate the profiler's ability to measure vertical velocity and radar reflectivity profiles in clouds and precipitation, with particular emphasis on the benefit provided by the coupler technology.

The enteric viruses are animal viruses that are principally transmitted by the fecal-oral route and replicate in the intestines. Though currently more than 120 enteric viruses are known from human feces (Murphy and Kingsbury, 1990) and ultimately find their way into sewage, two groups of these viruses, hepatitis A (HAV) and the Norwalk-family of viruses (also referred to as small round-structured viruses, SRSV), pose the greatest health risk to seafood consumers (for review see Metcalf et al., 1995; Jaykus et al., 1994; Goyal, 1984). Although HAV and Norwalk-like viruses are the predominant causes of shellfish-associated disease, caliciviruses, rotaviruses, astroviruses and hepatitis E virus (HEV) have also been associated with water- and/or food-transmitted diseases [for review see Metcalf et al., 1995; Jaykus et al., 1994; Morbidity and Mortality Weekly Report (MMWR), 1990; Richards, 1987].

Often, the term allergy causes confusion. A food allergy is defined by the American Academy of Allergy and Immunology (1984) as an "immunologic reaction resulting from the ingestion of a food or food additive." The term "immunologic" indicates that antibodies are produced in response to an allergen. "Food intolerance" refers to an abnormal physiologic response to an ingested food or food additive that is not proved to be immunologic in nature, including pharmacologic, metabolic, or toxic responses to food or food additives. There are many references on allergies and intolerance that include information relating to seafood (David, 1993; Husby et al., 1993; Metcalfe, 1991; Perkin, 1990; Brostoff and Challacombe, 1987, Breneman, 1984). In general, food intolerances and allergies have become an increasing problem. Americans are experiencing increased exposure to possible food allergies as well as a decreasing tolerance to foods because of the tremendous increase in food varieties and food additives.

Parasitic diseases transmitted from wild or domestic animals are called zoonoses. Marine zoonotic infections in humans can result from consumption and physical contact with contaminated seafood. Human parasitic infections associated with seafoods occur primarily by eating raw or undercooked fish. Generally, most are harmless to humans. The presence of parasites in fishery products is unappealing, and some can cause infections. Parasites caused only 4 percent of all food-borne disease outbreaks reported to the Centers for Disease Control (CDC) during 1983 through 1987 (Bean et al., 1990). Parasitic infections from seafood are much less common than are bacterial or viral infections, as indicated in a study by the National Academy of Science (NAS) (Ahmed, 1991). Only 39 cases from two outbreaks of fish-associated parasitic illnesses were reported to the CDC between 1978-1987. The NAS study found that parasitic infections in the United States are rare. Consumption of raw fish is relatively common in Japan, the Netherlands, and parts of South America. In Japan, where seafood is a dietary staple and often consumed raw, the incidence of anisakiasis has generally been estimated to exceed 1,000 symptomatic cases per year (Oshima and Kliks, 1986).

Seafood can become contaminated with pathogenic bacteria from three sources: (1) fecal pollution of the aquatic environment, (2) naturally occurring pathogens in the aquatic system, and (3) poor hygiene during harvesting, distribution, and food preparation (NAS, 1991). Viruses, parasites, and marine biotoxins are other environmental contaminants in some fishery products. These non-bacterial agents and their effects on human health are addressed in other parts of this section. This chapter on bacterial pathogens is divided into two parts. The first concerns the vibrios and related bacteria that naturally inhabit coastal waters. The second, entitled "Other Bacteria," includes brief descriptions of bacteria responsible for foodborne disease in many foods, including seafoods. Illnesses from these bacteria are mainly caused by poor food handling and preparation practices. Methods to limit exposure and reduce the risk of infection and disease are presented.

This decline occurred after the invasion and colonization of the lakes by the zebra mussel, Dreissena polymorpha. It has been hypothesized that the decline is a direct result of the competition by the zebra mussel decreasing the amount of food available. This study examined the potential of other stressors, e.g., the presence of toxic materials, as the contributing or main cause of the decline. Bioassays were performed with sediments from stations currently devoid of Diporeia (St. Joseph, MI) and with those still having Diporeia populations. In 28-d mortality bioassays, no mortality was observed with any of the sediments tested. However, in avoidance/preference tests, sediments from St. Joseph, that are now devoid of Diporeia, were avoided compared to sediments from Saugatuck, Grand Haven, and Muskegon, which still have a population. This avoidance was not changed by the addition of either Spirulina Plus super( registered ) or Tetramin super( registered ) flakes to the sediment as a food source but was reversed by a fresh layer of the diatom, Fragillaria crotonensis, on the sediment. These studies suggest that despite the high carbon content of the St. Joseph sediment, the nutritional content of the sediment was limited.

The resulting set of spill scenarios is then used as a basis for planning a robust response capability that should be able to handle all likely real spills. For model developers to be able to support these expectations there are a number of criteria that must be satisfied: (1) Models must develop and retain the data necessary to answer key response questions; (2) developers must understand the limitations in resolution imposed by the specific algorithms they use; and (3) the cardinality of the long geophysical records (with respect to modeled spill behavior) should be determined and the final collection of spill scenarios must span this set. This paper considers these specific constraints and discusses methods that can be used to quantify some aspects of the uncertainty in the output.

Components of sustainable development include economic profitability, environmental quality, and community well-being. For federal agencies, sustainable development is critical to their mission. The National Oceanic and Atmospheric Administration (NOAA) has always embraced a linkage between economic and environmental goals. However, integration of these elements into its internal operations is a new concept. This article provides a general discussion of sustainable development principles and approaches to incorporating these principles internally, and specific sustainable development initiatives at NOAA. To meet the demands of NOAA's mission requirements - including sustainable development - and the many environmentally related Presidential Executive Orders, NOAA is developing an environmental, health, and safety management information system (MIS).

Although contamination of U.S. estuarine sediments is widely recognized as a serious problem, the actual severity and extent of this problem is poorly known on a national scale. Data derived from chemical analyses, toxicity tests, and benthic community analyses of sediments (constituting the sediment quality triad) were reviewed. The objectives of this review were to estimate the incidence of chemical contamination and the spatial extent of toxicity and degraded benthic communities, and to evaluate the relative degree of correspondence between matching pairs of the triad components. Based upon two inventories of data compiled from numerous studies, similar to 26-27% of sediment samples nationwide had chemical concentrations sufficiently high to warrant concern for potential toxicological effects. The spatial extent of toxicity in acute amphipod bioassays ranged from 0% to 85% among urban bays and estuaries, and averaged similar to 7.5% of the surficial areas studied thus far. Among three estuarine provinces, the surficial extent of degraded benthos ranged from 7% to 22% for measures of low infaunal abundance, and from 4% to 10% for measures of low species richness. The percentages of samples with slightly elevated chemical concentrations (42-49%) and the spatial extent of toxicity in sensitive, sublethal bioassays (43-61% of estuarine surficial area) indicated that slightly degraded conditions were much more widespread. Data compiled in many field studies conducted along portions of all three coasts of the United States, indicated that numerical sediment quality guidelines could be used to predict toxicity in sediments, and that results of laboratory toxicity tests often were predictive of degraded benthos.

Size range of yellow perch examined was 72 to 118 mm. In October at a 15-m site off Muskegon, both Gammarus spp. and Isopoda were found in nearly 71% of age-0 yellow perch stomachs, and accounted for 71 and 26% of the diet by weight respectively. The following spring at the 15-m site (June 1999), Gammarus spp. and Isopoda were only a small part of age-1 yellow perch diet, and Chironomidae and Mysis relicta dominated the diet. In October at depths of 25 to 35 m, M. relicta, was found in 100 and 80% of the age-0 yellow perch containing food off Muskegon and St. Joseph, respectively, and comprised over 96% of the diet by weight. Gammarus spp., Isopoda, and M. relicta were eaten in higher numbers than would be expected based on their low abundance in the environment. The high occurrence of Gammarus spp. and Isopoda in yellow perch diet may indicate ongoing changes in the nearshore benthic community.

Experiments demonstrated the importance of conditioning both open tubular cadmium reactor (OTCR) and packed copper-coated cadmium columns to achieve 100% reduction efficiency. The effects of segmentation bubbles in the OTCR upon reduction efficiency and baseline noise in nitrate analysis are investigated using an auto-analyzer. Metal particles derived from segmentation bubbles in OTCR result in interference with continuous flow analyses. Therefore packed columns are recommended for determination of low level nitrate in natural waters.

As the tropical oceans warm during an El Nino event, the precipitation intensity, water vapor mass, and temperature of the tropical atmosphere are observed to increase, reflecting a more vigorous hydrologic cycle. The enhanced latent heat release and resultant atmospheric warming lead to an increase in the emission of longwave radiation. Atmospheric global climate models, forced with observed sea surface temperatures (SSTs), accurately reproduce the observed tropospheric temperature, water vapor, and outgoing longwave radiation changes. However, the predicted variations in tropical-mean precipitation rate and surface longwave radiation are substantially smaller than observed. The comparison suggests that either (i) the sensitivity of the tropical hydrological cycle to ENSO-driven changes in SST is substantially underpredicted in existing climate models or (ii) that current satellite observations are inadequate to accurately monitor ENSO-related changes in the tropical-mean precipitation. Either conclusion has important implications for current efforts to monitor and predict changes in the intensity of the hydrological cycle.

Improvement is shown at 24, 48, and 72 h. Although this improvement can be shown without any preconditioning of the data, the question of accounting for forecast difficulty is addressed, building upon the work of Neumann. A decrease in the initial position errors over the same period is also shown. Track forecast errors generated by the Atlantic climatology and persistence (CLIPER) model (run in "best-track" mode) are used as a measure of forecast difficulty. Using the annual average CLIPER errors in a regression against the official forecast errors yields an equation giving an expected error for each year under consideration. The expected error (representing forecast difficulty) is then subtracted from the observed official errors. The resulting set of differences can then be examined for long-term trends, difficulty having been accounted for. Fitting a straight line to these differences (1970-98) yields the result that official forecast errors have decreased by an average of 1.0% per year at 24 h, by 1.7% per year at 48 h, and by 1.9% per year at 72 h. A second-order fit, however, suggests that the rate of improvement has increased during the latter half of the period.

Extreme precipitation events (those above the 90th percentile) occur at all phases of the El Nino-Southern Oscillation (ENSO) cycle, but the largest fraction of these events (for the West Coast as a whole) occur during neutral winters just prior to the onset of El Nino. In the tropical Pacific these winters are characterized by enhanced activity on intraseasonal (roughly 20-60 day) timescales and by relatively small sea surface temperature anomalies compared to ENSO winters. For these winters, lagged composites are used to document a coherent relationship between the location of extreme precipitation events along the West Coast and the location of enhanced tropical convection on intraseasonal timescales. The evolution of the atmospheric circulation patterns associated with the extreme precipitation events is described and a physical mechanism relating tropical intraseasonal oscillations, the "pineapple express," and the extreme precipitation events is proposed and illustrated.

Seasonal maximum ice cover for the combined area of the Great Lakes was the lowest on record (15%) relative to winters since 1963, a distinction formerly held by winter 1982/83 (25%), which was also an exceptionally strong El Nino winter. Maximum ice covers set new lows in winter 1997/98 for Lakes Erie (5%), Ontario (6%), and Superior (11%), tied the all-time low for Lake Huron (29%), and came close to tying the all- time low on Lake Michigan (15%; all-time low is 13%). Here the authors compare seasonal progression of lake-averaged ice cover for winter 1982/83, winter 1997/98, and a 20-winter normal (1960-79) derived from the NOAA Great Lakes Ice Atlas and discuss the 1997/98 ice cover in detail. Winter air temperatures in the Great Lakes were at or near record high levels, storms were displaced farther to the south over eastern North America, and precipitation was below average in the northern portion of the Great Lakes region.

(1999) AN - 17638177; 4775724 AB - In a recent paper, Schaller et al. (1999) presented an anlaysis of spawner-recruit data that contrasts productivity patterns for stream-type chinook salmon (Oncorhynchus tshawytscha) stocks from the upper Columbia and Snake rivers (which must pass eight or nine dams) with those of stocks from the lower Columbia River (which must pass three or fewer dams). The main premise of the authors is that differences in productivity between upper and lower river stocks are primarily due to the number of dams that each must pass. In this commentary shortcomings of this analysis are examined that are believed to be serious enough to weaken the conclusions of the paper. It is clear that hydroelectric development has played a role in the decline of Columbia and Snake River stocks. The analaysis by Schaller et al, provides compelling arguments that dams are the overriding cause of the decline of upper river stocks, and hence that removing dams will restore salmon populations to historical levels. However, due to problems with the experimental design, shortcomings in the data used, and weakness in the assumption that different evolutionarily significant units (ESUs) should respond identically to environmental change, these results do not rule out other factors contributing to the decline of these stocks. Other confounding factors, such as the increases in hatchery production and the implementation of a smolt transportion program, which were initiated in the late 1970s, render the situation even more complex. It is a concern that an overly simplistic interpretation of the data will lead to the neglect of other important factors, such as overfishing, habitat degradation (freshwater and marine), hatchery fish - wild fish interactions, and increases in exotic predators.

Despite their widespread use, the impacts of these pesticides on the neurological health of wild salmon are not well understood. Of particular concern are the organophosphate and carbamate insecticides that block synaptic transmission by inhibiting neuronal acetylcholinesterase. Here the effects of diazinon, an organophosphate insecticide, on alarm pheromone induced antipredator responses and homing behaviour in chinook salmon (Oncorhynchus tshawytscha), is assessed. Nominal exposure concentrations were chosen to emulate diazinon pulses in the natural environment. In the antipredator study, diazinon had no effect on swimming behaviour or visually guided food capture. However, the pesticide significantly inhibited olfactory-mediated alarm responses at concentrations as low as 1.0 mu times L super(-1). The results suggest that olfactory-mediated behaviours are sensitive to anticholinesterase neurotoxicity in salmonids and that short-term, sublethal exposures to these insecticides may cause significant behavioural deficits. Such deficits may have negative consequences for survival and reproductive success in these fish.

Import and export markets for such products can be expected to expand, particularly as increased research begins to remove physiological and animal husbandry barriers, and over fishing of wild stocks require replenishment through increased aquaculture efforts. Some unique risk factors associated with aquacultured products must be addressed and controlled as the United States relies more on aquacultured species. This is particularly the case due to concerns about increased risk exposure to our national sea animals, vegetation in the marine estuarine, and fresh water environments when live animals are transferred across state, provincial, and national borders. Nonetheless, application of the Hazard Analysis Critical Control Point (HACCP) principles as a risk management tool in aquaculture will work provided the proper infrastructures are executed. We must also overcome the historical regulatory pitfalls of HACCP dealing with concept understanding, critical control point definitions, misunderstanding of and between the complimentary roles of sanitation and process controls, agency and industry commitment, inspector and consumer acceptance and effective training.

The principal Hg source is the Nyanza Superfund site, a former textile dye production facility. Mussels were transplanted to eight locations in the Sudbury River watershed for 12 weeks. Tissue total Hg concentration increased significantly in mussels at the station closest to the Nyanza site. Mussel growth, which increased downstream with distance away from the site, was significantly negatively correlated with tissue concentrations of total Hg and positively correlated with average temperature. Due to growth differences, uptake was best assessed by changes in content. Tissue total hg and MeHg burdens were greatest in mussels at two stations closest to the Nyanza site, with less Hg accumulated in downstream mussels. However, the MeHg content in mussel tissue increased significantly at all Sudbury River stations, indicating that MeHg was bioavailable in all portions of the river evaluated.

This paper starts with a description of a coupled numerical model (MCCM, Multiscale Climate Chemistry Model), which is based on the Penn State/NCAR nonhydrostatic mesoscale model (MM5) and the RADM2 gas-phase chemical reaction scheme. The second part of the paper presents a simulation for the Mesolcina Valley, the core region of the VOTALP Valley Campaign, and adjacent regions. The simulation was done using the nesting facility of the coupled meteorology/chemistry model. The horizontal resolution for the innermost nest was 1 km. The simulations depict the daily thermally induced valley and mountain wind system and the advection of pollutants with this wind system. It becomes obvious that in the model simulation highly polluted air from the Po Basin is transported into the Alpine valleys during the day. During the night cleaner air is brought downward with the mountain winds. Cross sections from the high-resolution model results give a closer look at the inflow and outflow of pollutants into and from the Mesolcina Valley.

In contrast, recruitment of young-of-the-year white sturgeon to juvenile and adult stages is successful in the unimpounded Columbia River downstream of Bonneville Dam. The availability and size of preferred prey during the period when white sturgeon larvae begin exogenous feeding could be an important determinant of year-class strength. To explore this issue, we examined the diet composition of 352 larval and young-of-the year white sturgeon collected from 1989 through 1991 in the lower Columbia River. Samples were collected downstream from Bonneville Dam and upstream from the dam in Bonneville and The Dalles Reservoirs. Fish that ranged in size from 15 to 290 mm in total length fed primarily on gammarid amphipods (Corophium spp.) during all months. This diet item became increasingly important to all sizes of white sturgeon examined as they grew. The length of Corophium spp. eaten by larval and young-of-the-year white sturgeon increased with increasing fish length (r super(2) = 45.6%, P < 0.0001). Copepods (Cyclopoida), Ceratopogonidae larvae, and Diptera pupae and larvae (primarily chironomids) were also consumed, especially at the onset of exogenous feeding. A small percentage of white sturgeon were found with empty stomachs during June (1.6% downstream from Bonneville Dam) and July (4.5% downstream and 2.6% in the reservoirs). Diets of larval and young-of-the year white sturgeon from both impounded and free-flowing sections of the Columbia River were similar and we found no evidence of larval starvation in the areas investigated, areas currently supporting healthy white sturgeon populations.

However, the scientific and technical basis for this improved performance is far from certain and the efficacy of these technologies remains open to question. In this paper we examine the physical basis for ESE devices and identify areas of controversy and gaps in our knowledge of lightning and lightning protection that need to be considered in assessing ESE devices and in their future development. The ESE devices considered here are lightning attractors, and in that sense, their purpose is the same as that of conventional "lightning rods." ESE devices, however, differ from conventional lightning rods in that they are equipped in some fashion to increase the efficiency of lightning attraction and thereby to extend the effective range of protection over and above that of conventional lightning rods.

The generality of this food web transfer was demonstrated using three different combinations of copepods and juvenile fish during different seasons. Fish were not exposed directly to the toxic dinoflagellates but were fed toxin-laden copepods in order to examine sublethal vectorial intoxication. Toxins were shown to move from fish viscera to muscle tissue within periods of 2-6 h to 25 h. A new toxin detection method was used in this first stepwise demonstration of multi-trophic-level intoxication of a planktonic food chain by G.breve. Micellar electrokinetic capillary electrophoresis with laser-induced fluorescence allowed measurements of toxins at trace levels and nanoliter-sized volumes critical for planktonic food web transfer studies.

We examined spatial patterns in population characteristics (density, biomass, mean body length) and physiological condition (lipid content, length-weight) of the amphipod Diporeia spp. in Lake Michigan by collecting samples at up to 85 sites in late summer 1994 and 1995. Variables were examined relative to water depth and three lake regions: south, central and north. Most major river systems are found in the south, and this region is more nutrient-enriched compared to the north. 2. Over all sites, mean density was 5240 m super(-2), biomass was 4.1 g dry wt m super(-2), and mean body length was 5 mm. While maximum densities were related to depth, with a peak at 30-70 m, greatest densities occurred on the west side of the lake, and low densities were found in the south-east, north-east and lower Green Bay. High densities in the west probably resulted from upwelling, and reduced densities in the south-east may reflect food competition with Dreissena polymorpha (zebra mussel). 3. Lipid content, weight per unit length, and mean length declined with increased water depth, but depth-related trends were most evident in the south. Overall, mean lipid content and weight per unit length were significantly lower in the south (16.6% dry wt, 0.59 mg at 5 mm body length) compared to the north (23.7% dry wt, 0.78 mg at 5 mm body length). These regional differences may have resulted from greater diatom availability in the north and competition from D. polymorpha in the south. Triacylglycerols and phospholipids were the dominant lipid classes in all three regions. Although the mean proportion of triacylglycerols, the energy-storage lipid, was lower in the south than in the north, regional differences in proportions of lipid classes were not significant. 4. Mean lipid content and weight per unit length of Diporeia in the south were lower than values found in the late 1980s prior to the establishment of Dreissena. Mean lipid content of mature individuals is now at levels considered a minimum for successful reproduction.

Among 31 allozyme loci resolved in 91 samples from 63 populations of chinook salmon in rivers and hatcheries throughout British Columbia, population heterozygosities averaged 0.084 (range 0.048-0.108) and were typical of values for populations in other regions. A hierarchical gene diversity analysis indicated that 91.3% of the total allele-frequency diversity was attributable to within-population variability; the remaining 8.7% was attributable to geographic variability among populations, which was partitioned into among-river (3.3%), among-area (3.5%), and among-region (1.9%) components. Two major groups of populations appeared in the principal components analysis and in cluster analysis of genetic distances. A coastal group included populations in four subgroups: Central coast, Georgia Strait, lower Fraser River, and west Vancouver Island. An inland group included six subgroups: Nass River, Skeena River, north Thompson River, upper and mid-Fraser River, south Thompson River, and lower Thompson River. The geographic extents of the inland and coastal groups largely coincided with the geographic distributions of stream- and ocean-type juvenile forms and may reflect postglacial colonization by two ancestral lineages that survived in Pleistocene refugia. The presence of genetically undifferentiated stream-type fish in coastal streams populated by ocean-type fish may reflect either postglacial life history differentiation from ancestral ocean-type fish or life history flexibility of ocean-type fish.

We were able to address some of these concerns by combining information about current laser safety standards, retinal damage mechanisms for humans, and research on eye anatomy for humans, cetaceans, and pinnipeds. To estimate the irradiance at the retina, the image size at the retina and pupil diameter must be known. We estimate the smallest spot size using retinal resolution or visual acuity for six species of cetaceans and five species of pinnipeds. A sensitivity ratio was calculated for each species using the ratio of the irradiance at the retina of the marine mammal to the irradiance at the retina of humans. The sensitivity ratio was used to suggest exposure limits for the various species. Because the human eye is more sensitive than either the cetacean or pinniped eye, we conclude that laser energies that are eye-safe for humans will also be safe for marine mammals, and higher laser irradiances may be permissible if illumination of humans is avoided.

Lactating females frequented the rookery to nurse their pups until weaning; most non-lactating females left the rookery for the season. Females spent over 70% of their time at sea except in 1993 when they spent 59% of their time at sea. The mean foraging trip length in the winter and spring ranged from 3.3 to 4.6 d; the mean nursing visit ranged from 1.2 to 1.4 d. The duration of foraging trips and nursing visits was variable over the season for individuals but no pattern of change was detected. Interannual and seasonal differences were not significant for time at sea, visits ashore, or foraging-trip duration before, during, or after the 1992-1993 El Nino event. Pups spent an average of 66.6% of their time ashore and up to three days away from the rookery during their mother's absence. Most females and pups stayed associated until April or May. The results suggest that seasonal movement of prey is more important in determining attendance patterns late in the lactation period than increasing energy demands of the pup.

Survey data indicated densities of 4.48 groups/100 km super(2), or approximately 3,531 harbor porpoises (95% C.I. 2,206-5,651) in Bristol Bay and 0.54 groups/100 km super(2), or 136 harbor porpoises (95% C.I. 11-1,645) for Cook Inlet. Efforts off Kodiak Island resulted in densities of 1.85 groups/100 km super(2), or an abundance estimate of 740 (95% C.I. 259-2,115). Surveys off the south side of the Alaska Peninsula found densities of 2.03 groups/100 km super(2) and an abundance estimate of 551 (95% C.I. 423-719). Surveys of offshore waters from Prince William Sound to Dixon Entrance yielded densities of 4.02 groups/100 km super(2) and an abundance estimate of 3,982 (95% C.I. 2,567-6,177). Combining all years and areas yielded an uncorrected density estimate of 3.82 porpoises per 100 km super(2), resulting in an abundance estimate of 8,940 porpoises (CV = 13.8%) with a 95% confidence interval of 6,746-11,848. Using correction factors from other studies to adjust for animals missed by observers, the total number of Alaska harbor porpoises is probably three times this number.

N1 - Last updated - 2014-05-07 ER - TY - RPRT T1 - Effects of Hurricane Floyd on Water Levels Data Report AN - 1521397344; 8020056 AB - Hurricane Floyd was the strongest and most damaging hurricane of the 1999 Atlantic season. At its peak strength it was classified as a Category 4 hurricane on the Saffir/Simpson Hurricane Scale. By the time it made landfall near Wilmington, NC it had weakened to a Category 2 hurricane. Most of the damage and casualties attributed to the storm were due to the heavy rainfall and flooding caused by the passage of the storm along the U.S. Atlantic coastline. The hardest hit area was eastern North Carolina. This report presents the data collected by the Center for Operational Oceanographic Products and Services (CO-OPS) during the passage of Floyd in the week of September 13-19, 1999. The storm track resulted in significant storm surges at almost all of CO-OPS' National Water Level Observation Network (NWLON) stations along the Atlantic Coast. At three stations, observed water levels exceeded their historical records. Previous major storm event data reports are listed in the reference section at the end of this report.

N1 - Last updated - 2016-05-27 ER - TY - JOUR T1 - Penaeid Shrimp Landings in the Upper Gulf of California in Relation to Colorado River Freshwater Discharge AN - 14540027; 10586014 AB - Commercial catches of estuarine-dependent crustaceans and fish in the upper Gulf of California have declined recently. The possibility of a lack of Colorado River flow, due to upstream dam construction, contributing to this decline is explored for the shrimp fishery. A correlation analysis of shrimp landings at San Felipe Baja California with freshwater discharges from the Colorado River to the northern Gulf of California shows that shrimp landings are significantly correlated with same year river discharge, as well as with the number of trawlers. The mechanisms by which river discharge might affect the shrimp fishery are unknown. Speculation regarding postlarvae and juvenile stage survival and salinity or nutrient gradients suggests some possibilities.

All platforms showed different assemblages occupying midwater and bottom areas. Midwaters were dominated by young-of-the-year or juveniles up to 2 yrs old. Larger rockfishes were rarely seen in midwater. Platform bottom fish assemblages were dominated by larger individuals. Densities were similar at both levels for any given platform, but the total biomass was greater at the bottom because of the larger fish size. More species also were found at the bottom, probably because more habitat types were present. Fish assemblages differed among platforms, probably because some platforms were located in northerly, more productive waters. The implications of these findings in the debate over whether or not to remove older, decommissioned platforms is discussed.

Fishers from each fishery have contended that the other causes high mortality rates to their respective species. Experimental harvesting was conducted using realistic fishing techniques, intensity, and frequency. Naturally occurring oysters and clams and transplanted hatchery-raised clams were sampled before and after harvesting. Harvesting of both species substantially decreased live oyster populations compared with populations on unharvested control reefs. Both types of harvesting conducted together had similar effects as to each type conducted separately. Oyster harvesting alone decreased the number of live, unharvested clams at only one of two sites. Oyster harvesting had no effect on live, transplanted clam numbers. Clamming and oyster harvesting should be permitted on some reefs, but other areas should be protected from both types of harvesting to maintain large oyster and clam populations.

AN - 16338297; 7746 AB - PURPOSE: An amendment to 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 the occurrence of bycatch and incidental catch by United States commercial fishermen who hold Federal permits for the catch of HMS and use pelagic longline gear in the Atlantic Ocean. Pelagic longline gear is the dominant gear used by United States 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 (or sizes) of fish, mammals, birds, and sea turtles that are not the intended target species. Four alternatives, including a No Action Alternative (Alternative 1), which would maintain the status quo, and several subalternatives, are considered in this draft supplemental EIS. Under the preferred alternative (Alternative 2B), the regulations would establish time and area closures to pelagic longline fishing to reduce the bycatch of HMS as well as the bycatch of marine mammals and sea birds. An area in the central and western Gulf of Mexico would be closed to fishing from March through September, and a second area in the South Atlantic Bight/Florida East Coast would be closed year-round. The other subalternatives include the prohibition of the use of pelagic longline gear (Alternative 2A), the prohibition of the use of live bait on pelagic longline gear (Alternative 2C), measures to rig longlines so hooks are fished deeper in the water column (Alternative 2D), the prohibition of the setting of a pelagic longline in water temperatures greater than 68 degrees Fahrenheit in the Grand Banks region (Alternative 2E), the prohibition of the setting of a pelagic longline from 3:00 PM and 9:00 PM (Alternative 2F), the requiring of the use of circle hooks to increase the survival of bycatch and incidental catch (Alternative 3A), the reducing of pelagic longline soak times to increase the survival of bycatch and incidental catch (Alternative 3B), and the reducing of fishing capacity in the Atlantic pelagic longline fishery (Alternative 4). POSITIVE IMPACTS: By reducing bycatch and incidental catch, the regulatory amendments would improve the sustainability of the HMS species. NEGATIVE IMPACTS: Certain fishery management provisions, particularly gear restrictions and area closures, could result in economic losses to fishing interests.

However, little progress has been made in sustained global actions to reverse their degraded state. It has been no small feat for the world community to come to agreement on international instruments identifying environmental and resource problems, but it is another matter altogether to muster the scientific community and the political will to enact necessary policy reforms and devote necessary funding to restore and protect valuable marine ecosystems. An ecosystems approach is emerging for the assessment and management of coastal waters around the globe utilizing modular strategies for linking science-based assessments of the changing states of large marine ecosystems to socioeconomic benefits expected from achieving long-term sustainability of their resources. To assist developing countries in implementing the ecosystems approach to marine resources development and sustainability in international waters, the Global Environment Facility and its $2 billion trust fund has been opened to universal participation that builds on partnerships with the United Nations Development Programme, the United Nations Environmental Programme, and the World Bank.

AN - 36409982; 7725 AB - PURPOSE: The amending of the fishery management plan (FMP) for the snapper grouper fishery in the South Atlantic region is proposed. The region includes areas of the Atlantic Ocean extending from the North Carolina/Virginia border through the Atlantic side of the Florida Keys to 83 degrees west longitude. Amendment 12 to the FMP would adjust fishing activities with respect to the red porgy species. Six proposed actions and a number of other possible options are considered in this draft supplement to the final EIS of August 1983. Action 1 would establish a maximum sustainable yield of approximately 5,285.4 metric tons. Action 2 would establish an optimum yield, the amount of harvest that can be taken by United States fishermen while maintaining a total spawning stock size (biomass), of 10,000 metric tons. Action 3 would establish a maximum fishing mortality threshold between 0.58 and 0.33 and a minimum stock size threshold of 3,000 metric tons, resulting in a rebuilding timeframe of 18 years beginning in 1999. Action 4 would prohibit the harvesting and possession of red porgy. Action 5 would modify the Snapper Group Framework by adding management options that could be implemented via framework action. Action 6 would modify the Snapper Grouper Limited Access System to allow same-owner permit transfers regardless of vessel size for individuals harvesting snapper grouper species with a non-transferable 225 trip limit permit. POSITIVE IMPACTS: The amendment to the FMP would stabilize and protect the snapper grouper fisheries in the South Atlantic. Bag limits and quotas would place a cap on the number of participants and prevent future increases in fish mortality. NEGATIVE IMPACTS: The prohibition of landings would create short-term economic hardships for some commercial operators. Commercial fishing interests would experience declines in gross annual revenue for red porgy. 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 et seq.).

PCTC initiated an effort in 1997 to develop a conservation strategy of native salmonid fish (trout, steelhead trout, salmon, and whitefish) occurring on approximately 1.7 million acres of the company's timberlands in the three-state region. The planning area for the purposes of this draft is 17.3 million acres as actions taken by PCTC could affect the habitat of the species of concern in the larger area. The planning area has been divided into 17 river basins or watersheds including the following: Kootenai River (Lower, Middle, and Upper), Flathead River, Swan River, Blackfoot River, Bitterroot River, and Clark Fork River (Lower, Middle, and Upper) in Montana; Upper St. Joe River, Lochsa River, and Little North Fork Clearwater River in Idaho; and Ahtanum Creek, North Riffe Lake, Lewis River, and Lower Tieton River in Washington. Key issues identified during scoping include those related to geology and soils, water resources and hydrology, water quality and contaminants, vegetation resources, fisheries and other aquatic resources, wildlife habitat, land use, recreation resources, visual and aesthetic resources, cultural resources, social resources, economics, and air quality. Four alternatives, including a No Action Alternative, are considered in this draft EIS. PCTC's plan includes the conservation of native salmonids and their ecosystems while conducting timber logging within a framework of long-term regulatory certainty and flexibility. The incidental take permit would allow PCTC to take the species of concern within limits. In addition to issuance of the permit, action alternatives under consideration include the Internal Bull Trout Conservation Plan Alternative and the Simplified Prescriptions Alternatives. The Internal Bull Trout Conservation Plan Alternative would involve the implementation of a package of defensive, science-based land management practices and conservation measures that could be developed and implemented by PCTC. This alternative could potentially be used to authorize incidental take for single species or listed species only. The Simplified Prescriptions Alternative would represent a general approach to road, riparian buffer, and grazing restrictions, with either no or minimal commitments to other practices that conserve fish. Regardless of the action alternative selected, the plan would include monitoring components to insure the effectiveness of the management system. Habitat conservation prescriptions associated with the permit would cover road construction, riparian management, range management, land use planning, legacy and restoration activities, administration and implementation provisions, and adaptive management and monitoring. POSITIVE IMPACTS: The permit issuance would allow PCTC to exploit its timber resource while implementing a conservation strategy. NEGATIVE IMPACTS: PCTC's timber logging and road construction activities would result in the sedimentation of receiving streams, reducing water quality and resulting in the degradation of salmonid habitat.

Preparation date: December 10, 1999 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - HAMPTON ROADS CROSSING STUDY (STATE PROJECT: 0064-114-F12, PE-102), CITIES OF CHESAPEAKE, HAMPTON, NEWPORT NEWS, NORFOLK, POQUOSON, SUFFOLK, AND VIRGINIA BEACH, AND ISLE OF WIGHT AND YORK COUNTIES, VIRGINIA. AN - 16356470; 7715 AB - PURPOSE: The construction of a crossing of Hampton Roads, located in southeastern Virginia, is proposed. Hampton Roads is the waterbody and harbor located between the mouth of the James River to the west and the Chesapeake Bay to the east. The term has been adopted locally and also refers to the metropolitan region that surrounds the Hampton Roads Harbor. The study areas includes the cities of Chesapeake, Hampton, Poquoson, Newport News, Norfolk, Suffolk, and Virginia Beach, as well as the counties of Isle of Wight and York. Four alternatives, including a No-Build Alternative, are considered in this draft EIS. Project termini would include the Interstate Highway 64 (I-64)/I-664 interchange in Hampton, the I-64/I-564 interchange in Norfolk, Virginia Route (VA) 164 near Coast Guard Boulevard in Portsmouth, and the I-64/I-264/I-664 interchange in Chesapeake. Two potential tunnel designs are under consideration for each of the candidate build alternatives, namely, the steel tube design and the concrete tube design. The steel tube design, which is similar to the existing I-664 tunnel, is based on a generally circular tube section that provides space above and below the travelway for ventilation. The ventilation is accommodated with a fully transverse system. French air is supplied from ducts under the traffic, passed through the travelway, and exhausted in ducts above the ceiling. The overall height of the circular, steel tube section in 40 feet. The concrete tube design offers some advantages due to its smaller outside dimensions. The design features a rectangular section and employs a jet air longitudinal ventilation system that supplies fresh air from one end of the tunnel and pumps it longitudinally in accordance with traffic movements, prevailing winds, and weather conditions. The overall height of the tube section in 30 feet. Regardless of the alternative route and tube design chosen, the crossing would include bridge tunnel, bridge, and culvert sections. The estimated costs of the action alternatives range from $1.2 billion to $2.7 billion. POSITIVE IMPACTS: The project would improve accessibility, mobility, and goods movement in the Hampton Roads metropolitan area, relieve congestion affecting the I-64 Hampton Roads Bridge Tunnel. The reduced height of the concrete tube design, as compared to the steel tube design, would decrease the area and volume of dredging required for the tunnel, thereby reducing excavation costs and habitat impacts. An armor stone structure would crease 74 to 138 acres of benthic habitat. NEGATIVE IMPACTS: Rights-of-way requirements would result in the displacement 39 to 128 residences, eight to 10 businesses, and possibly one church, one community facility, and one government building, and two utilities. In addition, 2.3 to 116.6 acres of farmland would be displaced. Traffic-generated noise in excess of federal standards would affect 66 to 373 dwelling units, but only 11 to 25 units would experience substantial increases over current noise levels. From 27 to 43 dwelling units would experience both absolute and relative increases in noise levels. Construction activities could affect the piping plover, a federally protected species. The structure would traverse approximately 30,000 to approximately 55,000 feet of waterbodies, impacting 72 to 136 acres of benthic habitat and encroaching directly on 0.96 to 18.31 acres of wetlands and indirectly on 1.38 to 7.2 acres of wetlands. One district listed on the National Register of Historic Places and one district considered eligible for listing could be affected, and two land areas eligible or considered eligible could also be affected. The project would encounter a number of hazardous waste sites.

Preparation date: December 9, 1999 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - SHOCK TRIAL OF THE WINSTON S. CHURCHILL (DDG 81) OFFSHORE OF MAYPORT, FLORIDA; NORFOLK, VIRGINIA; OR PASCAGOULA, MISSISSIPPI. AN - 36407728; 7705 AB - PURPOSE: The implementation of a shock trial for the Winston S. Churchill (DDG 81) by the Navy off the coast of Florida, Mississippi, or Virginia, is proposed. The Churchill is the third ship in a new flight of 23 guided missile destroyers being acquired by the Navy. Such ships are referred to as the Flight IIA ships and they represent the largest single upgrade the Alreigh Burke class destroyer. The entire manned ship must be shock tested at sea since, unlike computer modeling and component testing, such a test would provide the means to assess the shock response of the entire ship and the interaction of the ship's systems and components. A No Action Alternative and the proposed action are considered in this draft EIS. Under the proposed action, the ship would be subjected to a series of three to four 10,000-pound explosive charge detonations sometime between May 1 and September 30, 2001. The ship and the explosive charge would be brought closer with each successive detonation to increase the severity of the shock. The gradation in severity would allow the Navy to fully assess the survivability of the ship and its systems. The shock trial would be conducted at a rate of one detonation per week to allow time to perform detailed inspections of the ship's systems prior to the next detonation. The tests would be conducted offshore of Naval Station (NS) Mayport in Florida, NS Norfolk in Virginia, or NS Pascagoula in Mississippi. From an operational perspective, the candidate test sites are nearly equal in suitability. The three NSs have sufficient homeported ships to support the trial. Test areas offshore of the NSs could meet all other operational requirements, including a water depth of at least 600 feet, suitable weather and sea state conditions, a manageable volume of commercial ship traffic, and proximity to aircraft, a ship repair facility, and an ordnance- loading facility. Most environmental impacts of the shock trial would be similar regardless of the site chosen. POSITIVE IMPACTS: The data gathered from the shock test would allow the Navy to assess the survivability of Flight IIA ships, providing information of vital importance in judging the viability of the ship and its systems under battle conditions. NEGATIVE IMPACTS: Seabirds, pelagic fish, sea turtles, and marine mammals in the vicinity of the test site could be killed or injured, and floating plankton and sargassum organisms at the detonation site would be killed. The risk of mortality and injury to marine mammals and sea turtles would be higher offshore of NS Norfolk than at the other two sites, where risk levels would be approximately equivalent. Ship traffic passing within 10 nautical miles of the detonation point would need to alter their courses. Metal fragments would be deposited on the seafloor, and explosive products would be released into the sea and the atmosphere, though levels of these pollutants would be minimal.

The virtually blank-free NAA procedures fittingly complement precautions employed in sampling and sample preparation of biological matrices. Results from instrumental NAA procedures used to establish baseline values and time trends for elements in human tissues demonstrate the advantages as well as the limits of these procedures for nanomole and, in a considerable number of instances, subnanomole elemental levels. In addition, subnanomole mass fractions have been determined with extremely low limits of detection by employing NAA with radiochemical separations isolating very low levels of radioactivity from the matrix background. The elements reviewed in this article include Cr, Se, Pt, and others that have been determined by NAA at subnanomole levels in human tissues and body fluids and in biological macromolecules.

AN - 70817960; 10519658 AB - Ciguatoxins are lipophilic polyether toxins which concentrate in the viscera and flesh of coral reef associated finfish (Hessel et al., 1960). In this study, we quantify the adverse effects of ciguatoxin on fish embryos by microinjection into the egg yolk of medaka (Oryzias latipis) embryos. Embryos microinjected with 0.1-0.9 pg/egg (ppb) of ciguatoxin exhibit cardiovascular, muscular, and skeletal abnormalities and those injected with higher levels (1.0-9.0 pg/egg) exhibit significantly reduced hatching success. The sensitivity of embryonic fish to direct oocyte exposure indicates that maternal transfer of low levels of ciguatoxin may represent an unrecognized threat to the reproductive success of reef fish and a previously undetected ecological consequence of proliferation of ciguatoxin-producing algae in reef systems increasingly impacted by human perturbations.

Our ability to estimate natural climate variability, against which claims of anthropogenic signal detection must be made, is reviewed. The current situation suggests control runs of global climate models may give the best estimates of natural variability on a global basis, estimates that appear to be accurate to within a factor of 2 or 3 at multidecadal timescales used in detection work. Present uncertainties in both observations and model-simulated anthropogenic signals in near-surface air temperature are estimated. The uncertainty in model simulated signals is, in places, as large as the signal to be detected. Two different, but complementary, approaches to detection and attribution are discussed in the context of these uncertainties. Applying one of the detection strategies, it is found that the change in near-surface, June through August air temperature field over the last 50 years is generally different at a significance level of 5% from that expected from model-based estimates of natural variability. Greenhouse gases alone cannot explain the observed change. Two of four climate models forced by greenhouse gases and direct sulfate aerosols produce results consistent with the current climate change observations, while the consistency of the other two depends on which model's anthropogenic fingerprints are used. A recent integration with additional anthropogenic forcings (the indirect effects of sulfate aerosols and tropospheric ozone) and more complete tropospheric chemistry produced results whose signal amplitude and pattern were consistent with current observations, provided the model's fingerprint is used and detection carried out over only the last 30 years of annually averaged data. This single integration currently cannot be corroborated and provides no opportunity to estimate the uncertainties inherent in the results, uncertainties that are thought to be large and poorly known. These results illustrate the current large uncertainty in the magnitude and spatial pattern of the direct and indirect sulfate forcing and climate response. They also show detection statements depend on model-specific fingerprints, time period, and seasonal character of the signal, dependencies that have not been well explored. Most, but not all, results suggest that recent changes in global climate inferred from surface air temperature are likely not due solely to natural causes. At present it is not possible to make a very confident statement about the relative contributions of specific natural and anthropogenic forcings to observed climate change. One of the main reasons is that fully realistic simulations of climate change due to the combined effects of all anthropogenic and natural forcings mechanisms have yet to be computed. A list of recommendations for reducing some of the uncertainties that currently hamper detection and attribution studies is presented.

During this time, the focus of JdFR seismicity has been Axial Volcano, where a total of 9055 earthquakes have been detected (1669 located). This activity occurred within 48 discrete swarms along the summit caldera and flank rift zones. From August 1991 to May 1996, Axial Volcano exhibited only one swarm with > or =50 earthquakes. From May 1996 to November 1997 swarm activity increased significantly with five swarms of > or =50 earthquakes. Activity culminated at the volcano in January 1998 with an 11-day, 8247-event swarm that was the result of a major eruption along the summit and southern flank. Seafloor deformation sensors indicated pre-eruption swarms in October 1995, May 1996, and June 1996 coincided with subsidence of the caldera floor. The 1996-1997 swarm activity increase also coincided with horizontal extension of the north rift zone, consistent with pre-eruption deformation of the volcano. Following the 1998 eruption, swarm activity dramatically decreased and no earthquakes have been detected since April 1998. This is the longest aseismic period ( approximately 1 yr) observed at the volcano since acoustic monitoring began, suggesting the January 1998 swarm marked the end of an eruptive cycle at Axial Volcano.

Significantly higher numbers of bacteria were found in the plume versus background stations and depths, due largely to 5 samples with high numbers (to 1.8 X 10 (super 5) /ml) in far field stations. Highest ratios (0.20) of metal depositing capsuled bacteria to total bacteria were found in the near-field (over caldera) plume. An unusual capsule form (FeCap), that dominated the near field plume capsule populations, was present in all plume samples, but were absent in background samples. Multi-cell filaments, metal-encrusted sheathed clusters and matrix-enmeshed colonies, all uncommon in the water column, were also present in plume samples.

[1999] is applied in a search for trends in the Holocene acidity of waters in the transition zone between North Atlantic Deep Water and Antarctic Bottom Water (AABW). A clear signal emerges that the carbonate ion content of waters in this zone declined during the past 8000 years. In order to determine whether this decline represents a strengthening of the northward penetrating tongue of low CO (sub 3) (super =) content AABW or a global reduction of CO (sub 3) (super =) ion, measurements were made on a core from the Ontong Java Plateau in the western equatorial Pacific. Evidence for a similar decline in CO (sub 3) (super =) ion over the course of the Holocene was obtained lending support of the latter explanation. Such a drop is consistent with the recent finding by Indermuehle et al. [1999] that the CO (sub 2) content of the atmosphere (as recorded in the Taylor Dome Antarctica ice core) rose by 20-25 ppm during the past 8000 years.

CH (sub 4) / (super 3) He ratios were found to be 5-10 times greater than previously reported values for unsedimented ridges. An average delta (super 13) C value of -32.7+ or -0.8 per mil was determined for CH (sub 4) concentrations > 10 nM and CH (sub 4) /Mn ratios were determined to be 2.2. Hydrogen concentrations as high as 183 nM were measured; however most were < 10 nM. Microbial oxidation of methane was negligible (<0.001 day (super -1) ) during this sampling period. However, microbial hydrogen oxidation was sufficient to explain decreased H (sub 2) concentrations measured at "older" downstream stations. Copyright 1999 by the American Geophysical Union.

The instruments recorded a gradual 9-cm extension over a 405-m baseline leading up to the eruption, and then an abrupt, 4-cm contraction at the time of the eruption. An elastic point-source deformation model shows that deflation of Axial's summit can explain both the 4-cm distance decrease at the extensometer array and a 3.2-m subsidence measured by another instrument in the caldera, if the pressure source is located at a depth of 3.8 km below the center of the caldera. The 9-cm distance increase may represent pre-eruption spreading across the rift zone. Copyright 1999 by the American Geophysical Union.

The earthquake swarm was detected using the U.S. Navy hydrophones in the northeast Pacific Ocean. The earthquake swarm lasted 11 days and produced 8247 detected (1037 located) earthquakes. During the first two days of the swarm, earthquake activity migrated from the summit caldera approximately 50 km along the south rift zone of Axial Volcano at rates of 0.92 + or - 0.13 and 0.23 + or - 0.09 m s (super -1) . Earthquake epicenter migration is characteristic of a lateral magma dike injection. The largest three swarm earthquakes occurred within the caldera. Their timing and mechanisms are consistent with adjustment of the caldera floor as magma is removed from beneath the summit. Earthquakes with short T-wave rise times (shallow focal depths) cluster at two spots along the summit and south rift zone, and are considered possible seafloor eruption sites. In situ ground deformation and hydrothermal plume monitors, and later shipboard observations, confirmed the occurrence of a seafloor volcanic eruption at the volcano's summit.

Moorings 2 km apart along the eruption fissure recorded temperature increases of approximately 0.6 degrees C up to 115 m above bottom within hours of initial seismic activity. Water temperatures at the mooring sites remained high for about 5 days, then declined steadily over the next 2 weeks. A response cruise 18 days after the eruption found hydrothermal temperature anomalies of approximately 0.1 degrees C over the eruption site, and a more intense and much thicker plume 20 km downstream of the eruption. We estimate the steady-state heat flux required to produce this distal plume, evidence of discharge conditions perhaps 1-13 days after the eruption, as 60-230 GW. The Axial eruption thus produced the largest vent field heat flux yet measured, but these high levels lasted less than 3 weeks. Copyright 1999 by the American Geophysical Union.

During a January 1998 volcanic episode, pressure records from the central caldera showed a significant increase in pressure, indicating caldera subsidence of over 3 m. This observed subsidence is interpreted to represent volcanic deflation as magma is erupted and/or injected into the volcanic flanks. Temperature anomalies of nearly 0.45 degrees C were also observed. A comparison of the subsidence record with hydroacoustic recordings indicates a continuous volcanic tremor signal coincident with the subsidence event. The time-coincidence of subsidence of the summit caldera with migration of epicenters into the volcanic rift zones confirms that during the 1998 episode, the volcanic flanks were supplied by lateral dike injection from a central magma body, rather than locally derived magma sources.

Plumes detected in 1997 before the event had relatively high (super 3) He/heat consistent with the volatile-rich character of the known hydrothermal vents within the summit caldera. A response cruise in February 1998 immediately after the event failed to detect any event plumes, but instead found an intense steady-state type plume with high-temperature signals, moderate (super 3) He enrichments, and low (super 3) He/heat ratios. This plume was present over the caldera and extended a considerable distance off axis. In contrast, all of the plumes detected during follow-up cruises in July-September 1998 had moderate temperature signals, high (super 3) He concentrations, and elevated (super 3) He/heat ratios. Comparison with previous events suggests that the low (super 3) He/heat plume sampled in February was either the remnant of an event plume which had already migrated off axis, or an event plume-like discharge which was smeared out by strong currents. It is likely that the high (super 3) He/heat plumes observed in July-September were derived from the injected dike or from the new lava flow. Copyright 1999 by the American Geophysical Union.

A sheet flow more than 3 km in length and 500-800 m wide erupted from the uppermost south rift is the site of a robust hydrothermal system. 1998 lavas occur over about 9 km of the upper south rift zone, or about 20% of the along-axis length of the seismicity event ( approximately 50 km). The estimated volume of lava erupted is 18-76 X 10 (super 6) m (super 3) for the extrusion and 100-150 X 10 (super 6) m (super 3) for the intrusion. The total volume is consistent with the volume from modeling of seafloor strain measurements recorded during the event. Copyright 1999 by the American Geophysical Union.

The forecast technique is based on canonical correlation analysis (CCA), a multivariate linear statistical model that relates patterns in the predictand field to patterns in the predictor field. In this CCA design, four consecutive 3 month predictor periods are followed by a lead time and a single 3 month predictand period. Cross validation is used to estimate the skill in the forecasts. The forecasts are expressed in terms of departures from climatological probabilities of three equiprobable categories for above-, near-, and below-normal rainfall. Expressing the forecasts in terms of probability anomalies communicates the level of confidence in the forecasts. Forecast verifications have been performed using the Heidke skill (S) score. For the Sahel the July-September 1997 rainfall prediction at 1 month lead showed reasonable skill. Furthermore, it is shown that the Sahel rainfall in July-September is influenced at least partly by El Nino-Southern Oscillation (ENSO). In addition, Sahel rainfall is affected by the sea surface temperature pattern in the Atlantic Ocean and perhaps the Indian Ocean. For southern Africa, the S score was +30, suggesting a moderately good forecast for the region as a whole. The results also indicate that ENSO plays an important role in modulating rainfall variations in southern Africa. JF - Journal of Geophysical Research. D.

Its absolute magnitude, areal extent, and rapid development have raised a serious concern among decision makers because of its possible impact on global ecosystems. In this study, El Nino consequences for land ecosystem were examined using the new AVHRR-based three-channel index (VT), widely used for monitoring drought around the world. The VT index was used to identify a typical pattern of vegetation conditions in southern Africa during the recent El Nino years. Features and trends of the 1997-98 El Nino including its intensity, extent, and impact on vegetation are also discussed.

A case study analysis was made of the socioeconomic context of the three primary user groups in Montego Bay Marine Park, Jamaica: fishers, hoteliers and watersports operators. The primary means of data collection were document analysis, interviews with individuals representative of user groups, focus groups and participant observation. The results regarding user's awareness, user groups' relations with the managing agency, relations among and within user groups, resource use patterns, and sociocultural values demonstrate the need to: increase public awareness of the benefits of the Park, increase user awareness of Park management activities, increase user involvement in Park management, and develop intersectoral coordination. These findings provide useful guidance for future Park management and, in a more general context, illustrate the importance of socioeconomic assessments for reef management.

While an objective of the Magnuson-Stevens Fishery Conservation and Management Act (Magnuson-Stevens Act), the US Federal law controlling fisheries management in the Exclusive Economic Zone (EEZ), had always been to prevent overfishing, the attendant mechanisms for accomplishing the objective were not included in law. Some of the most significant amendments of the SFA were the addition of three new national standards, against which all proposed fishery conservation and management measures are measured, and the amendment of several other existing standards. Among the most important changes from the standpoint of conservation were changes that relate to national standard 1, regarding the prevention of overfishing and the rebuilding of overfished resources. Although the SFA did not use the term "precautionary approach" explicitly, the concept is implicitly expressed in several provisions of that Act. In developing the guidelines for implementation of the national standards, the National Marine Fisheries Service (NMFS) incorporated precautionary concepts to ensure that compliance with the SFA's measures to prevent and end overfishing are satisfied. In addition, the NMFS developed further technical guidance to assist fishery scientists and managers in providing advice that appropriately considers risk, relative to the scientific information available, such that meaningful protection is afforded marine stocks and stock complexes. Such protection extends not only to consideration of stock recruitment, but also to maintenance of sustainable levels of stock biomass and biodiversity.

Blubber from these whales contained capital sigma PCBs, capital sigma DDTs, capital sigma chlordanes, HCB, dieldrin, mirex, capital sigma toxaphene and capital sigma HCH, generally in concentration ranges similar to those found in white whales from the Canadian Arctic but lower than those in white whales from the highly contaminated St Lawrence River. Males from the Cook Inlet and Eastern Chukchi Sea stocks had higher mean concentrations of all contaminant groups than females of the same stock, a result attributable to the transfer of these organochlorine contaminants (OCs) from the mother to the calf during pregnancy and lactation. Principal component analysis of patterns of contaminants present in blubber showed that the Cook Inlet stock appeared to have identifiable contaminant patterns that allowed the stock to be distinguished from the others. Our results also showed that blubber from the three Alaskan stocks was a source of contaminant exposure for human subsistence consumers, but the health risks from consumption are currently unknown.

The Columbia Glacier is an important tidewater glacier to monitor because of its present rapid retreat, its generation of icebergs, and its vicinity to oil-tanker traffic in and out of the Port of Valdez, Alaska. We have established routine monitoring of the Prince William Sound area using SAR aboard the Canadian RADARSAT on a semi-weekly basis. To demonstrate the use of this data, four ERS-1 and seven RADARSAT SAR images from 1992 to 1998 are used in this study to monitor the long-term retreat of the Columbia Glacier. A loss of 17.7 plus or minus 0.2 square kilometers is measured from 1992 to 1997, with 38.4% of this change occurring from 1993 to 1994. Also, hazards such as icebergs are monitored in near real-time. SAR is an efficient and cost-effective means of monitoring glaciers, where cloud cover and logistical costs and difficulties hamper other data-collection efforts. These data are available to U.S. Government users and would be of benefit to the Prince William Sound region if used operationally.

The analysis shows preferential rainfall during predawn hours. Nighttime mixing typically caused the predawn rainfall to mix downward into higher salinity subsurface waters. In contrast, afternoon rainfall, although weaker, generally produced a stable shallow layer of very low salinity. Consequently, sea surface salinity (SSS) exhibited a weak diurnal cycle, with anomalously low salinity in the late afternoon and anomalously high salinity at night. At 1 m depth, the SSS diurnal cycle anomalies were similar to 0.005 psu. Although nearly two orders of magnitude less than the SSS standard deviation for this region, the anomalies were significant at the 95% confidence level.

Perhaps the most damaging environmental impact of aquaculture occurs when untreated effluent is discharged into surrounding bodies of water. Effluent is generated from either water exchange to maintain water quality in ponds or for the harvest of a crop. If the effluent is enriched with nutrients, eutrophication within the receiving body of water may result. Although aquaculturists are moving toward systems where the discharge of effluent is minimized, the problem of effluent disposal continues to challenge the industry. Clearly, low cost and effective treatments of aquaculture effluent are needed to ensure the sustainability of the industry.

The super(14)C analyses were undertaken to provide direct fossil vs modern (biomass) carbon source discrimination data for a subset of summer and winter 1996-1997 samples collected within the Denver metropolitan area. Samples were prepared for super(14)C accelerator mass spectrometry measurements using techniques specially developed for small samples, i.e., <100 mu g C. For the days and sampling periods analyzed the median and interquartile range of the winter blank corrected fraction of modern carbon was 23% (16-34%) at Welby and 27% (25-37%) at Brighton. The summer samples exhibited a more mixed signature with a median and interquartile range of 47% (9-70%). Source samples yielded super(14)C signatures consistent with expectation. We conclude fossil-derived sources contribute substantially in both seasons and at both locations; however, the biomass carbon component dominates episodically in the summer.

This series shows a gradual increase in biomass of medusae from 1979 to 1989, followed by a dramatic increase in the 1990s. The median biomass increased tenfold between the 1982-1989 and 1990-1997 periods. Most of this biomass was found within the Middle Shelf Domain (50 < z < 100 m). The greatest rate of increase occurred in the north-west portion of this domain. Whether this dramatic increase in biomass of gelatinous zooplankton has resulted from some anthropogenic perturbation of the Bering Sea environment or is a manifestation of natural ecosystem variability is unclear. However, several large-scale winter/spring atmospheric and oceanographic variables in the Bering Sea exhibited concomitant changes beginning around 1990, indicating that a possible regime change occurred at this time.

Several recent studies have shown that the super(32)P-postlabelling method can be used to detect and measure the levels of DNA modified by large, hydrophobic aromatic compounds in teleosts. Moreover, the levels of hepatic DNA adducts in wild fish positively correlate with the concentrations of polycyclic aromatic compounds (PACs) present in marine sediments in several cases, and a strong positive correlation has been observed between sediment concentrations of PACs and the prevalence of neoplastic lesions in liver of marine flatfish. Laboratory studies with model PACs and sediment extracts also have shown that the PAC-DNA adducts formed are persistent and have chromatographic characteristics similar to DNA adducts detected in wild fish. These findings suggest that the levels of hepatic DNA adducts found in fish tissues can function as molecular dosimeters of exposure to potentially genotoxic environmental contaminants, such as high molecular weight PACs. The super(32)P-postlabelling assay has been used as a marker of exposure to potentially genotoxic contaminants in environmental monitoring studies, such as NOAA's National Status and Trends (NS&T) Program and in the Bioeffects Surveys of NOAA's Coastal Ocean Program.

A protein phosphatase inhibition assay for DSP toxins revealed the presence of low levels of okadaic acid-like activity in blue mussels (Mytilus edulis) at sampling sites in the Frenchman Bay-Eastern Bay region. All other sites along the Maine coast were negative. Phytoplankton populations from this area were dominated by Dinophysis norvegica, a known toxic species. Two additional known toxic species of Dinophysis were also found: Dinophysis acuminata and D. rotunda. However, all plankton samples were negative for okadaic acid-like activity. Examination of the epiphytic communities from areas where mussels showed okadaic acid-like activity revealed the presence of the toxic dinoflagellate Prorocentrum lima in association with the brown alga, Ectocarpus sp. Epiphytic samples rich in P. lima were active in the phosphatase inhibition assay. Subsequent analysis of these samples using LC-MS/MS identified the presence of dinophysis toxin-1 (DTX-1). Empty P. lima thecae identified in the digestive tract of mussels from these areas indicate that P. lima is consumed by mussels. This is the first confirmation of P. lima in northern United States coastal waters and identifies DSP as a potential public health issue.

Initially, a prototype system will be developed for the Gulf of Maine and the Gulf of Mexico. Later, the system will expand to all US coastal areas affected by HABs. Sources of data include routine monitoring efforts, event driven monitoring, topical research initiatives (ECOHAB), and the NODC archive. Routine monitoring data and biological data will be held in a new database. A common interface will link this database to other databases that hold HAB-related data such as NODC's Ocean Profile Database and Ocean Current Time Series Database. A large data management system like this will allow researchers and resource managers to access pertinent data for a particular region for decision making, or to compile a historical perspective on events in a particular region. The combination of physical, chemical, and biological data from many sources in this system will provide researchers with a tool to assist in developing forecast models for harmful algal blooms.

In the last 15 years these HAE events have affected 20 of the 23 coastal states. The costs to the states and the industry are estimated at 50 million dollars annually. Emerging technologies such as remote sensing, spectral analysis, and internet access can provide an early warning system for states and industry while new laboratory methods can expedite identification of toxin type and levels. On the local level the mussel watch programs maintained by states and plankton sampling supported by volunteers can be used to verify the data received from the federal government. In response to the growing need for support the US HAB National Contingency Plan will use a National Clearinghouse for direct transfer of information and access to the technical expertise of federal and state agencies, academia, and private industry on a day-to-day basis and an early alert system for most toxic effects. A National Event Response Coordinator will alert all federal agencies of an event and arrange for the specific expertise and technical assistance to be provided on a national and local level by appropriate agencies.

We examined temporal and spatial variability in spawning by bay anchovy (Anchoa mitchilli), and in distribution and abundances of its pelagic early-life stages, throughout Chesapeake Bay. On two cruises in June and July 1993, ichthyoplankton and zooplankton were collected on 15 transects at 18.5-km (10 nautical mile) intervals over the 260-km length of the bay. Finer-scale sampling was carried out in a grid of stations between two transects on each cruise. Regional abundance patterns of bay anchovy eggs and larvae in the lower, mid, and upper Bay were compared with zooplankton abundances, environmental variables, and biovolumes of two gelatinous predators--the scyphomedusa Chrysaora quinquecirrha and the lobate ctenophore Mnemiopsis leidyi. Abundances of anchovy eggs, and, especially, larvae were higher in July than in June. Baywide daily egg production increased from 4.25 x 10 super(12) in June to 8.43 x 10 super(12) in July. Concentrations of zooplankton that are potential anchovy prey nearly doubled on a baywide basis between June and July, while biovolumes of the ctenophore declined. Except for scyphomedusan biovolumes, all analyzed organisms differed regionally in abundance and were patchily distributed at 1-km to 10-km sampling scales. Negative correlations between larval anchovy abundances and gelatinous predator biovolumes suggested that predation may have controlled abundances of bay anchovy early-live stages. Biomasses of adult anchovy, estimated from daily egg productions, were higher in the lower Bay and remarkably similar--23,433 tons in June and 23,194 tons in July. Most spawning by bay anchovy occurred during July in the seaward third of Chesapeake Bay, emphasizing the importance of this region for recruitment potential of the Bay's most abundant fish.

To accurately evaluate the significance of this bycatch, information on population structure is required. We have examined the population structure of this species in the northwest Atlantic Ocean using mitochondrial DNA (mtDNA) sequence and nuclear microsatellite data. Samples from four previously proposed summer breeding populations--the Gulf of Maine, eastern Newfoundland, the Gulf of St Lawrence and West Greenland--were analysed. Control-region sequences revealed a significant partitioning of genetic variation among most of these summer populations, indicating that northwest Atlantic harbour porpoises should not be considered one panmictic population. Analysis of females alone yielded the highest levels of population subdivision, suggesting that females are more philopatric than males. At least three management units may be defined for harbour porpoises in the northwest Atlantic based on these data. Analysis of six microsatellite loci failed to detect significant population subdivision. Male-mediated gene flow may maintain homogeneity among nuclear loci, while female philopatry is sufficient to produce a signal of population subdivision in the maternally inherited mtDNA genome. mtDNA analyses also indicate that winter aggregations of harbour porpoises along the US mid-Atlantic states comprise animals from more than one summer breeding population.

Compared to the rest of the USA, the oysters collected from sites located along the southeastern coasts, from North Carolina to the Florida panhandle, display high concentrations of arsenic (As) in their soft tissues. In this area, As concentrations can be elevated in sediments and in bivalves, although exact spatial correspondence between the two is infrequent. As concentrations in waters and food (plankton and suspended particles) directly surrounding the mollusks collected in winter are not unusually high. Phosphate deposits and soil pesticide residues are the hypothesized main sources of this As, and the enrichment mechanism appears to result from a mixture of processes including atmospheric deposition, river and aquifer inputs, and ocean up-welling. In the southeast oysters, the large bio-accumulation of As may also be affected by the seasonal cycle of adsorption/solubilization of As observed in several estuarine and coastal areas, by local physico-chemical parameters such as temperature, salinity, and the nature of sediments (e.g. high contents in iron, calcium, phosphate, and organic material). Even at these very high concentrations, the As present in the southeastern oysters does not appear to present a health threat to humans or to marine life.

The estuarine microbial food web plays an important role in nutrient cycling and transfer of nutrients to higher trophic levels. The present study examined the effects of agricultural pesticides on the estuarine microbial food web. Polyurethane foam substrates were used to collect microbial communities from a reference tidal creek in the North Inlet National Estuarine Research Reserve (Georgetown, SC, USA). Colonized substrates were brought into the laboratory and exposed to the following commonly used agricultural pesticides: atrazine (and a metabolite, deethylatrazine), endosulfan, and chlorpyrifos. Chlorophyll a, phototrophic carbon assimilation, dissolved oxygen, and phototrophic biovolume were significantly reduced at concentrations of 50 and 250 mu g/L atrazine and deethylatrazine. Generally, inhibition of the phytoplankton resulted in increased bacterial abundance and productivity, whereas heterotrophic ciliate and flagellate abundances were not affected. Total bacterial abundance, but not heterotrophic bacterial productivity, was significantly reduced with endosulfan treatments of 1 and 10 mu g/L. Endosulfan was primarily found to target the cyanobacteria. Changes in biomass reflected compositional shifts in the phototrophs. The abundance of heterotrophic ciliates and flagellates was significantly reduced at 10 mu g/L chlorpyrifos. Bacterial abundance and productivity increased, whereas phototrophic variables decreased. Agricultural pesticides were found to alter both functional and structural aspects of the estuarine microbial food web.

Results indicated significantly greater cover of seagrass at the traditional fishing village sites than the other two site groups. Analysis of dried sediments showed sediments at traditional fishing village sites were significantly enriched with phosphorus, though no significant difference in nitrogen was found between groups of sites. These results, together with studies showing that sediment nutrient pools can limit seagrass bed development, suggest that anthropogenic enrichment of lagoonal sediments by fishing waste over generational time scales may have caused substantial proliferation of seagrass beds.

We used studbook records to examine the effect of inbreeding upon juvenile viability and litter size in two endangered species that have recently been reintroduced to the wild: the Mexican wolf (Canis lupus baileyi) and the red wolf (C. rufus). We found that neither juvenile viability nor litter size was lowered by inbreeding in either taxon. In fact, both captive breeding programs appear to have less lethal equivalents than the median estimate for mammals. We did find that year of birth was correlated with increasing viability in both taxa. We conclude that there is no evidence that inbreeding depression will prove a major obstacle to the success of either recovery effort.

Stomatal conductance decreased markedly with increasing carbon dioxide in these species under most conditions. Coupled soil-vegetation-atmosphere models were used to scale up these single-leaf level measurements to simulate evapotranspiration at the regional scale from planting to harvest. The coupled modelling system introduced feedbacks over the season that are not present at the measurement level, which decreased the effect of carbon dioxide on evapotranspiration. Four sets of simulations were performed to evaluate specifically the magnitude of four feedbacks; two resulting from scale, surface layer and mixed layer feedback, one resulting from soil evaporation and one resulting from the interactions of stomatal conductance and the simulated canopy microclimate (physiological feedback). The feedbacks occurring from scale were consistent with previous analytical work indicating that transpiration becomes less dependent on stomatal conductance at larger scales. Evaporation from the soil has been generally neglected in past studies on carbon dioxide effects, but was especially important in decreasing the effects of carbon dioxide on evapotranspiration and showed a seasonal dynamic. The feedback resulting from physiological responses has also received less attention than the feedbacks from scale, but was only moderately important in these simulations. We also investigated the seasonal dynamics of how the observed increase in leaf area at elevated carbon dioxide affects evapotranspiration. Considering all the feedbacks and the observed increase in leaf area at elevated carbon dioxide, the simulated decrease in evapotranspiration was not negligible but was much less than the decrease in stomatal conductance. At the regional scale and maximum complexity in our model, the simulated decrease in seasonal evapotranspiration at doubled carbon dioxide (700 mu mol mol super(-1)) was 5.4% for soybeans and 8.6% for corn.

Forage species such as pandalid shrimp and capelin declined because of recruitment failure and predation, and populations have not yet recovered. Total trawl catch biomass declined >50% and remained low through the 1980s. In contrast, recruitment of high trophic-level groundfish improved during the 1980s, yielding a >250% increase in catch biomass during the 1990s. This trophic reorganization apparently had negative effects on piscivorous sea birds and marine mammals.

One potential virulence factor is p57 (also designated MSA for major soluble antigen), an abundant 57 kDa soluble protein that is predominately localized on the bacterial cell surface with significant levels released into the extracellular milieu. Previous studies of an attenuated strain, MT 239, indicated that it differs from virulent strains in the amount of surface-associated p57. In this report, we show overall expression of p57 in R. salmoninarum MT 239 is considerably reduced as compared to a virulent strain, ATCC 33209. The amount of cell-associated p57 is decreased while the level of p57 in the culture supernatant is nearly equivalent between the strains. To determine if the lowered amount of cell-associated p57 was due to a sequence defect in p57, a genetic comparison was performed. Two copies of the gene encoding p57 (msa1 and msa2) were found in 33209 and MT 239, as well as in several other virulent isolates. Both copies from 33209 and MT 239 were cloned and sequenced and found to be identical to each other, and identical between the 2 strains. A comparison of msa1 and msa2 within each strain showed that their sequences diverge 40 base pairs 5' to the open reading frame, while sequences 3' to the open reading frame are essentially identical for at least 225 base pairs. Northern blot analysis showed no difference in steady state levels of msa mRNA between the 2 strains. These data suggest that while cell-surface localization of p57 may be important for R. salmoninarum virulence, the differences in localization and total p57 expression between 33209 and MT 239 are not due to differences in msa sequence or differences in steady state transcript levels.

Photographic identification of individuals was used in a capture-recapture analysis to estimate the abundance and composition of the colony during 1993 to 1998. Results of the application of these techniques to Mediterranean monk seals were satisfactory, and allowed independent annual population estimates. No significant trends in abundance over the period 1993 to 1996 were detected, and the mean estimate for the period was 317 seals (CV = 0.16; 95% CI: 237 to 447). Environmental changes affecting suitability of habitat, particularly food availability, are suggested as major factors for limited population recovery during this period. In spring 1997, a mass mortality event reduced the population size to 109 individuals (CV = 0.14; 95% CI: 86 to 145). Mortality was age-specific and resulted in a severe change in the stage composition of the population. Adults were the most affected, and therefore the proportion of juveniles increased from an initial 12% before the event to about 29% after. As a result of both the decrease in seal numbers and the change in population composition, the number of individuals potentially contributing to reproduction fell to about 77 or fewer. This number may not be enough to maintain genetic variability and overcome the effect of demographic stochasticity. The demographic changes caused by the die-off are expected to have both positive and negative effects on the reproductive success of the colony. However, they are undoubtedly factors which potentially threaten the stability and survival of the colony in the near future.

A Report on the Telecommunications and Information Technology Gap in America. Revised. AN - 62408922; ED440200 AB - This report provides comprehensive data on the level of access by Americans to telephones, computers, and the Internet. It also provides valuable information about where Americans are gaining access and what they are doing with their online connections. These data, from the U.S. Census, provide a factual foundation for key policy initiatives to promote greater access for all Americans. Access to the Internet has soared for people in all demographic groups and geographic locations. At the end of 1998, over 40% of all U.S. households owned computers, and one-quarter of all households had access to the Internet. However, the digital divide persists between the information rich and the information poor, who include younger people, those with lower incomes and education levels, certain minorities, and those in rural areas or central cities. Whites are more likely to have access to the Internet from home than Blacks or Hispanics are from any location. Black and Hispanic households are approximately one-third as likely to have home Internet access as households of Asian/Pacific Islander descent and roughly two-fifths as likely as White households. Regardless of income level, Americans in rural areas lag in Internet access. At the lowest income levels, those in urban areas are more than twice as likely to have Internet access than those earning the same income in rural areas. For many groups, the digital gap has widened. An appendix contains information about the trendline study through 1998. (Contains 113 charts and 5 tables.)

AN - 62253336; ED456688 AB - This report uses data collected in the Survey of Income and Program Participation (SIPP) to examine the characteristics of postsecondary education students, their schooling costs, and avenues of financing education for the academic year 1993-1994. The SIPP provides information on all students who were enrolled at any time, for any duration, during the academic year, whether full or parttime. Of the 20.5 million postsecondary students enrolled at some point during the 1993-1994 school year, just under half (45%) were enrolled full time for the full year. Most of the 9.2 million full time students (74%) were undergraduates in their first 4 years of college (2-year and 4-year institutions) and about 1 in 7 were enrolled in graduate school. The remaining 11% were enrolled full time in noncollegiate schools, such as vocational, technical, or business schools. More than three in four full time students had a job at some point during the year. Data also indicate that the majority of full-time students were from families with an annual family income of less than $50,000. About 3 in 4 four full-time students were non-Hispanic White, and 1 in 10 was non-Hispanic Black. Women outnumbered men, and there were more women enrolled in the first 2 years of college. Postsecondary education was often expensive, and financial aid helped many students but not all. About 61%, or 5.6 million, full-time postsecondary students received some kind of financial aid. Graduate students and noncollegiate students were more likely than undergraduates to receive financial aid. The sources of financial aid varied, but students often received aid from more than one source. Dependent students were more likely to receive aid from multiple sources than were independent students.

Results suggest that the functional forms for both variables are nonlinear. Education is described significantly better by a trichotomy (represented by some high school, a high school diploma or greater, or a college diploma or greater) than by a simple linear function for both men & women. For describing the association between income & mortality, a two-sloped function, where the decrease in mortality associated with a US$1000 increase in income is much greater at incomes below than above US$22,500, fits significantly better than a linear function for both men & women. The different shapes for the two functional forms imply that differences in mortality may be primarily a function of income at the low end of the socioeconomic continuum, but of education at the high end. 3 Tables, 3 Figures, 51 References.

L., 1986. (super 238) U, (super 234) U and (super 232) Th in seawater. Earth Planet Sci. Lett. 80, 241-251.) observed uniformly in the open ocean. A prolific population of S microbes (e.g., Chromatium, Chlorobium sp.) flourishes at the O (sub 2) /H (sub 2) S interface. The source of elevated U at the redox boundary must be due to microbial uptake and subsequent release processes rather than dilution from oceanic uranium. Uranium oxidation state determinations in waters from 1, 22 and 30 m depth reveal that reduced U(IV) is not present in significant abundance, and that the chemical and/or biological reduction of hexavalent uranium is largely inhibited. Our results suggest that U and other trace constituents such as DOC, Sr, Ba, Fe(II), Mn(II) are greatly modified by direct and indirect microbial transformation reactions which are most concentrated across the redox transition zone in Framvaren Fjord.

In this fjord, a sharp decrease in pH above the O (sub 2) /H (sub 2) S interface facilitates the aerobic dissolution of MnO (sub 2) . In contrast, Fe(II) concentrations begin to increase only at the O (sub 2) /H (sub 2) S interface depth. Activity profiles reveal that dissolved (super 210) Po and (super 210) Pb are sequestered efficiently by particulates in surface waters. As polonium-210 and lead-210 activities descend down into the aerobic manganese reduction (AMR) zone, they are remobilized during the reductive dissolution of the carrier phase oxyhydroxides. Both (super 210) Po and (super 210) Pb are highly enriched at the O (sub 2) /H (sub 2) S interface where an active community of microbes, such as anoxygenic phototrophs (e.g., Chromatium, Chlorobium sp.), thrives. The coincident peaks in (super 210) Po, (super 210) Pb and microbial biomass suggest a strong biological influence on the behavior of these radionuclides. There is a strong covariance between the vertical distribution of Mn and Pb, indicating that their redox cycling is closely coupled and is likely microbially mediated.

The high mortality rate was unusual in that it was limited to a relatively small geographical area, occurred primarily within an inshore bay system separated from the Gulf of Mexico by barrier islands, and coincided with deaths of other taxa including birds and fish. Factors examined to determine the potential causes of the dolphin mortalities included microbial pathogens, natural biotoxins, industrial pollutants, other environmental contaminants, and direct human interactions. Emphasis was placed on nonpoint source pesticide runoff from agricultural areas, which had resulted from record rainfall that occurred during the period of increased mortality. Analytical results from sediment, water, and biota indicated that biotoxins, trace metals, and industrial chemical contamination were not likely causative factors in this mortality event. Elevated concentrations of pesticides (atrazine and aldicarb) were detected in surface water samples from bays within the region, and bay salinities were reduced to <10 ppt from December 1991 through April 1992 due to record rainfall and freshwater runoff exceeding any levels since 1939. Prolonged exposure to low salinity could have played a significant role in the unusual mortalities because low salinity exposure may cause disruption of the permeability barrier in dolphin skin. The lack of established toxicity data for marine mammals, particularly dermal absorption and bioaccumulation, precludes accurate toxicological interpretation of results beyond a simple comparison to terrestrial mammalian models. Results clearly indicated that significant periods of agricultural runoff and accompanying low salinities co-occurred with the unusual mortality event in Texas, but, no definitive cause of the moralities was determined.

The patterns and magnitudes of simulated and observed HNO sub(3) wet deposition are generally in good agreement around the globe. Scatterplots of model simulations versus aircraft observations for NO sub(x) and NO sub(y) find similar to 50% of the points within plus or minus 25%, find similar to 75% within plus or minus 50%, and show no systematic global biases. Both simulated and observed vertical profiles have similar shapes with high levels ( similar to 1 ppbv or greater) in the polluted boundary layer (BL), very low values in the remote BL, and values increasing from the middle to the upper troposphere. Simulated NO sub(y), HNO sub(3), NO sub(x) + PAN are also in good agreement with extensive lower free tropospheric (FT) observations made at Mauna Loa Observatory. In general, the level of agreement between simulation and observation is as good as the agreement between separate, but simultaneous, observations of NO, NO sub(x) or NO sub(y). As previous studies have shown, fossil fuel combustion and biomass burning control NO sub(x) levels in most of the lower half of the troposphere with a significant contribution from biogenic emissions. The exceptions are the remote low-NO sub(x) regions where BL and FT sources make comparable contributions. Unlike most previous studies, we find that the much smaller in situ FT sources generally dominate in the upper half of the troposphere. Lightning dominates in the tropics and summertime midlatitudes, stratospheric injection is the major source in the summer high latitudes. The exception is transported emissions from fossil fuel combustion, which dominate in winter high latitudes. Though seldom dominant, aircraft emissions do have a significant impact on the upper troposphere and lower stratosphere of the northern hemisphere extratropics. JF - Journal of Geophysical Research.

The simulations consider sorption onto hydrous Fe and Al oxides and particulate organic carbon, mineral precipitation, and organic and inorganic solution complexation of metals for two physical systems where newly formed oxides and particulate organic matter are either transported or retained along the chemical pathway. The calculations indicate that metal removal is a strong function of the physical system. Relative to direct discharge of ARD into streams, lower metal removals are observed where ARD enters streamwaters during the latter stages of neutralization by ambient groundwater after most of the Fe has precipitated and been retained in the soils. The mixing experiments, which represent the field simulations, also demonstrated the importance of dissolved metal to particle Fe ratios in controlling dissolved metal removal along the chemical pathway. Finally, model calculations indicate that hydrous Fe oxides and particulate organic carbon are more important than hydrous Al oxides in removing metals and that both inorganic and organic complexation must be considered when modeling metal removal from aquatic systems that are impacted by sulfide oxidation.

The requirement to evaluate fishing-related impacts on EFH developed into a profoundly difficult obstacle given the paucity of available information, specifically on the numerous types of gear utilized within the Gulf of Mexico. While there have been hundreds of studies published on gear impacts worldwide, the majority of these focus on mobile gear such as trawls. Currently, there are approximately 25 allowable gear types aside from trawls utilized within Federal waters of the Gulf of Mexico. Furthermore, as Gulf of Mexico EFH includes inshore and estuarine waters, there are several other gear types regulated by individual states that need to be evaluated. Due to the lack of specific information of fishery-related impacts, the Gulf of Mexico Fishery Management Council's Generic Amendment for Addressing Essential Fish Habitat Requirements was only partially approved by NOAA Fisheries. In an effort to correct these deficiencies, this evaluation attempts to review all utilized gear within the region and list the potential impacts a gear type may have on habitat, including literature citations of the pertinent studies that are available.

N1 - Last updated - 2014-05-06 ER - TY - JOUR T1 - Growth, Smoltification, and Smolt-to-Adult Return of Spring Chinook Salmon from Hatcheries on the Deschutes River, Oregon AN - 17482389; 4678721 AB - The relationship between smoltification and smolt-to-adult return (SAR) of spring chinook salmon Oncorhynchus tshawytscha from the Deschutes River, Oregon, was examined for four release groups in each of three successive years. Fish were reared, marked with coded wire tags, and released from Round Butte Hatchery, Pelton Ladder rearing facility, and Warm Springs National Fish Hatchery. Smolt releases occurred in nearly the same place at similar times, allowing a direct comparison of SAR to several characters representing smolt quality. Return rates varied significantly among facilities, varying over an order of magnitude each year. The highest average SAR was from Pelton Ladder, the lowest was from Warm Springs. Each of the characters used as metrics of smoltification--fish size, spring growth rate (February-April), condition factor, plasma hormone concentration (thyroxine, cortisol, and insulin-like growth factor-I [IGF-I]), stress challenge, gill Na super(+),K super(+)-ATPase activity, and liver glycogen concentration--varied significantly among facilities and seasonally within hatchery groups. However, only spring growth rate, gill ATPase activity, and plasma IGF-I concentration showed significant relationships to SAR. These characters and SAR itself were consistently lower for fish released from Warm Springs Hatchery than for fish from Round Butte Hatchery and Pelton Ladder. This demonstrates that differences in the quality of fish released by facilities may have profound effects on subsequent survival and suggests that manipulations of spring growth rate may be used to influence the quality of smolts released from facilities.

ER - TY - JOUR T1 - Diversion of Salmonid Smolts Tagged with Passive Integrated Transponders from an Untagged Population Passing through a Juvenile Collection System AN - 17471883; 4671538 AB - We evaluated a system to divert salmonid smolts tagged with passive integrated transponders (PIT) from the general migrant population as they passed through a juvenile collection system at a hydroelectric dam on the Snake River. Our goal was to maximize the diversion of PIT-tagged fish while simultaneously minimizing the diversion of untagged fish. The slide-gate system that was tested diverted 81% of PIT-tagged fish detected. The number of untagged fish entering the diversion system with every PIT-tagged fish was proportional to fish abundance and averaged one untagged fish for every PIT
