TY - JOUR T1 - The type IV leader peptidase/N-methyltransferase of Vibrio vulnificus controls factors required for adherence to HEp-2 cells and virulence in iron-overloaded mice. AN - 70072431; 9826339 AB - Vibrio vulnificus expresses a number of potential virulence determinants that may contribute to its ability to cause a severe and rapidly disseminating septicemia in susceptible hosts. We have cloned and characterized two genes encoding products related to components of the type IV pilus biogenesis and general secretory (type II) pathways by complementation of a type IV peptidase/N-methyltransferase (PilD) mutant of Pseudomonas aeruginosa with a V. vulnificus genomic library. One of the genes (vvpD) encodes a protein homologous to PilD and other members of the type IV peptidase family that completely restores this activity in a P. aeruginosa mutant deficient in the expression of PilD. The other gene (vvpC) encodes a homolog of PilC from P. aeruginosa, where it is essential for assembly of type IV pili. Phenotypic characterization of a V. vulnificus vvpD mutant, constructed by allelic exchange, showed that VvpD is required for the expression of surface pili, suggesting that the pili observed on V. vulnificus are of the type IV class. This mutant was also unable to secrete at least three extracellular degradative enzymes, and the localization of one of these (the cytolysin/hemolysin) to the periplasmic space indicates that these proteins are normally exported via the type II secretion pathway. Loss of VvpD resulted in significant decreases in CHO cell cytotoxicity, adherence to HEp-2 cells, and virulence in a mouse model. Capsule formation and serum resistance were not affected in the vvpD mutant, indicating that in addition to capsule, virulence of V. vulnificus requires type IV pili and/or extracellular secretion of several exoenzymes.

AN - 69167613; 9972314 AB - Vitellogenin (Vtg) is a yolk protein produced in the liver of oviparous animals in response to estrogen. Vitellogenesis is normally observed only in sexually mature females, but it can be induced in male and juvenile animals by exposure to exogenous estradiol (E2) or substances that mimic estrogens. The abnormal production of Vtg by males can, therefore, be used as a biological indicator for exposure to xenoestrogens. In this study, an enzyme-linked immunosorbent assay (ELISA) for measuring Vtg in English sole (Pleuronectes vetulus) was developed and validated. Plasmatic Vtg was purified from E2-injected male English sole using DEAE ion-exchange and Sepharose size-exclusion chromatography, and polyclonal antibodies against the purified Vtg protein were generated in rabbits. In this assay, a competition for the Vtg antibody was established between Vtg coated onto microtiter plate wells and free Vtg. Detection of adsorbed antigen-antibody complexes was achieved using a horseradish peroxidase conjugated anti-rabbit secondary antibody whose enzyme activity was revealed with 3,3',5,5'-tetramethyl benzidine (TMB) substrate. Assay conditions provided a detectable Vtg range of 10-450 ng ml-1 (85-20% of binding) of diluted sample. Plasma dilution curves from vitellogenic female and E2-treated male English sole showed parallelism with the standard dilution curve. We are presently conducting field and laboratory studies to investigate estrogenic and anti-estrogenic activity resulting from exposure to contaminants. JF - Comparative biochemistry and physiology.

Severe droughts of the twentieth century have had large impacts on economies, society, and the environment, especially in the Great Plains. However, the instrumental record of the last 100 years contains only a limited subset of drought realizations. One must turn to the paleoclimatic record to examine the full range of past drought variability, including the range of magnitude and duration, and thus gain the improved understanding needed for society to anticipate and plan for droughts of the future. Historical documents, tree rings, archaeological remains, lake sediment, and geomorphic data make it clear that the droughts of the twentieth century, including those of the 1930s and 1950s, were eclipsed several times by droughts earlier in the last 2000 years, and as recently as the late sixteenth century. In general, some droughts prior to 1600 appear to be characterized by longer duration (i.e., multidecadal) and greater spatial extent than those of the twentieth century. The authors' assessment of the full range of past natural drought variability, deduced from a comprehensive review of the paleoclimatic literature, suggests that droughts more severe than those of the 1930s and 1950s are likely to occur in the future, a likelihood that might be exacerbated by greenhouse warming in the next century. Persistence conditions that lead to decadal-scale drought may be related to low-frequency variations, or base-state shifts, in both the Pacific and Atlantic Oceans, although more research is needed to understand the mechanisms of severe drought.

The geoid is one such surface with a particular potential value, W (sub 0) . Spherical harmonic models of the Earth's external gravitational potential ("geopotential models") contain no explicit information about which level surface, out of the infinitely many that may be generated from the potential coefficients, is "the" geoid. Therefore, computing geoid undulations from a geopotential model requires additional information which should be carefully understood. Computer programs which compute gravimetric quantities from geopotential coefficients should contain prompts for this additional information. Submitted to the International Geoid Service (IGeS) is a FORTRAN program, geopot97 which accounts for all points in this paper except for the use of "correction coefficients" for topographic masses.

We use records of wind pressure time histories measured at a large number of taps on the building surface in the boundary layer wind tunnel of the University of Western Ontario. Time histories of bending moments in a frame are obtained by adding pressures at all taps tributary to that frame multiplied by the respective tributary areas and influence coefficients. The latter were obtained from the frame designs provided by CECO Building Systems. We compare results obtained by using the pressure time history records with results based on ASCE 7 standard provisions. The comparison suggests that provisions which use aerodynamic databases containing the type of data described in this work can result in designs that are significantly more risk-consistent as well as both safer and more economical than designs based on conventional standard provisions. We outline future research on improved design methodologies made possible by the proposed approach to the estimation of wind effects. We note that the use of the proposed methodologies is fully consistent with the ASCE 7 Standards insofar as these allow the use of wind-tunnel data for estimating wind load effects. Finally, We note that the proposed methodologies may be used for damage assessment for insurance purposes.

The potential predictability is measured as the ratio of the seasonal mean SST-forced signal and the internally generated seasonal mean noise. The authors' assessments are derived from the output of ensemble atmospheric general circulation model experiments forced with observed monthly SSTs for 1950-94. Using a perfect prognostic approach, results are presented on the predictability of upper-tropospheric circulation, North American land temperature, and precipitation. Seasonal predictability is shown to depend on the amplitude of the SST-forced signal, whereas the background noise is largely independent of SSTs. To zero order, that signal grows linearly with the amplitude of anomalous SSTs. An important departure from this is with respect to the phase of tropical Pacific SST anomalies, and the simulated atmospheric signals were stronger for ENSO's extreme warm phases compared to ENSO's extreme cold phases. This asymmetry can be traced throughout the teleconnection chain that links the ENSO forcing region with North American climate.

The system is an object-oriented, distributed, three-tiered client-server application that assimilates disparate observations and processes the data into a common framework for exposure, height and averaging time. The data are then examined collectively or by type, quality controlled and passed on to a scale-controlled objective analysis algorithm. Several products are derived from the analysis wind field and storm track, yielding effective tools for disaster assessment, emergency management, and recovery.

This policy states that a stock of Pacific salmon will be considered a distinct population, and hence a "species" under the ESA, if it represents an evolutionarily significant unit (ESU) of the biological species. NMFS has been implementing this policy for Pacific salmonids since it listed Snake River sockeye salmon in 1991. While genetic data play a central role in NMFS' ESU concept, they are not always available, and NMFS makes an effort to compile and evaluate available phenotypic, life history, and habitat information when conducting status reviews. Examples of how NMFS has used the ESU policy to delineate ESUs are provided. NMFS and the U.S. Fish and Wildlife Service (FWS) issued a joint policy on the recognition of distinct vertebrate population segments under the ESA on February 7, 1996. The concept of a distinct population segment can be applied to invertebrates in proactive efforts to protect species outside of the ESA. Genetic, phenotypic and life history data, and habitat characteristics can provide valuable information to managers of invertebrate species on which units to conserve in order to prevent ESA listings and recover species.

Based on this procedure, in north temperate 8-16 and 16-24 km layers the impact of El Chichon is a significant 10% ozone decrease 3-4 seasons after eruption, the impact of Pinatubo a significant 15% ozone decrease 7 seasons after eruption. In the 24-32 km layer the respective ozone decreases are 2% and 5%, the latter significant. In the north polar zone the ozone decreases following Pinatubo are a significant 20% and 10% in 8-16 and 16-24 km layers, but there are marginally significant ozone increases of 5% in the 24-32 km layer following both eruptions.

The three-dimensional structure of the complex between a TCR beta chain (mouse V beta 8.2) and the SAG staphylococcal enterotoxin B (SEB) at 2.4 Angstrom resolution reveals why SEB recognizes only certain V beta families, as well as why only certain SAGs bind mouse V beta 8.2. Models of the TCR-SEB-peptide/MHC class II complex indicate that V alpha interacts with the MHC beta chain in the TCR-SAG-MHC complex. The extent of the interaction is variable and is largely determined by the geometry of V alpha /V beta domain association. This variability can account for the preferential expression of certain V alpha regions among T cells reactive with SEB.

AN - 17140753; 4443223 AB - Antarctic fur seals (Arctocephalus gazella) in the South Shetland Islands are recovering from 19th-century exploitation more slowly than the main population at South Georgia. To document demographic changes associated with the recovery in the South Shetlands, we monitored fur seal abundance and reproduction in the vicinity of Elephant Island during austral summers from 1986/1987 through 1994/1995. Total births, mean and variance of birth dates, and average daily mortality rates were estimated from daily live pup counts at North Cove (NC) and North Annex (NA) colonies on Seal Island. Sightings of leopard seals (Hydrurga leptonyx) and incidents of leopard seal predation on fur seal pups were recorded opportunistically during daily fur seal research at both sites. High mortality of fur seal pups, attributed to predation by leopard seals frequently observed at NC, caused pup numbers to decline rapidly between January and March (i.e., prior to weaning) each year and probably caused a long-term decline in the size of that colony.

ER - TY - JOUR T1 - Copper tolerance by the freshwater algal species Oocystis pusilla and its ability to alter free-ion copper AN - 17139198; 4440014 AB - Previous studies with copper-stressed microcosms found that recovery was dependent on a copper-resistant algal species. One algal species, Oocystis pusilla, was able to bloom in microcosms that had been devoid of organismal activity for several weeks due to the addition of copper at a high concentration (31.5 mu M). In the present study, experiments were performed to characterize the range in tolerance of O. pusilla to copper, determine its growth under low and high pH regimes as a function of copper exposure, and to examine its ability to alter pH and ionic-copper activity (ICu) over time. Total-copper (TCu) concentrations up to 78.7 mu M and ICu values as high as 0.9 mu M had no negative effects on O. pusilla, indicating that it is highly copper-tolerant. The best growth for O. pusilla generally occurred in the range of 8-20 mu M (total or dissolved copper), indicating a hormetic effect (enhanced response at intermediate concentrations). Even though its abundance was severely depressed in a TCu solution of 157.5 mu M, this species was able to increase fourfold in 14 days. O. pusilla increased its numbers at a faster rate in high pH ( approximately 9) solutions; however, it was able to propagate when pH was lower ( approximately 7) and copper was high. These characteristics would allow this species to bloom in highly copper-stressed environments that would characteristically have a low pH. From this work, and related studies, we concluded that the primary mechanism allowing O. pusilla to reduce ionic-copper activity in culture solutions and microcosms was the release of organic copper-complexing ligands and that biomass sorption may have been important only at very high cell densities.

The concentrations of these bacteria ranged from 10 super(2) to 10 super(6) cells per ml of wet surficial sediment in mildly contaminated and noncontaminated sediments. A total of 23 strains of polycyclic aromatic hydrocarbon (PAH)-degrading bacteria were obtained. Based on partial 16S ribosomal DNA sequences and phenotypic characteristics, these 23 strains are members of the genus Cycloclasticus. Three representatives were chosen for a complete phylogenetic analysis, which confirmed the close relationship of these isolates to type strain Cycloclasticus pugetii PS-1, which was isolated from Puget Sound. PAH substrate utilization tests which included high-molecular-weight PAHs revealed that these isolates had similar, broad substrate ranges which included naphthalene, substituted naphthalenes, phenanthrene, biphenyl, anthracene, acenaphthene, and fluorene. Degradation of pyrene and fluoranthene occurred only when the strains were incubated with phenanthrene. Two distinct partial PAH dioxygenase iron sulfur protein (ISP) gene sequences were PCR amplified from Puget Sound and Gulf of Mexico Cycloclasticus strains. Phylogenetic analyses of these sequences revealed that one ISP type is related to the bph type of ISP sequences, while the other ISP type is related to the nah type of ISP sequences. The predicted ISP amino acid sequences for the Gulf of Mexico and Puget Sound strains are identical, which supports the hypothesis that these geographically separated isolates are closely related phylogenetically. Cycloclasticus species appear to be numerically important and widespread PAH-degrading bacteria in both Puget Sound and the Gulf of Mexico.

Particular attention is focussed on the inhibition cycles which regenerate the inhibitor. This leads to the definition of an idealized "perfect" inhibition cycle. It is demonstrated that for such an inhibitor in a stoichiometric methane/air flame, additive levels in the 0.001-0.01 mole percent range will lead to a decrease in flame velocity of approximately 30%. This efficiency corresponds roughly to the observed behavior of metallic inhibitors such as iron pentacarbonyl which is known to be as much as 2 orders of magnitude more effective than currently used suppressants. This correspondence between the behavior of a "perfect inhibitor" and iron carbonyl leads to the conclusion that only gas-phase processes can account for its inhibitive power.

AN - 16353822; 7185 AB - PURPOSE: The implementation of a fishery management plan (FMP) for Atlantic tunas, swordfish, and sharks is proposed. The target species are highly migratory species (HMS) inhabiting the Atlantic Ocean and adjacent waters. The management plan would replace the existing Atlantic shark and Atlantic swordfish FMPs. Several Atlantic HMS have been identified as overfished (western Atlantic bluefin tuna, Atlantic bigeye tuna, North Atlantic swordfish, and large coastal sharks). For most Atlantic HMS fisheries, the U.S. accounts for only a fraction of total fishing-related mortality of the target species, foreign fishing interest accounting by far for the majority of the catch. Bycatch mortality of Atlantic HMS can further depress overfished stocks. Other problems, common to many fisheries, include assuring optimal data collection and streamlining and updating the management program. The management program would incorporate all existing management measures for North Atlantic swordfish and Atlantic sharks, though provides notable modifications and additions to these measures. The FMP in this final EIS would include rebuilding measures for HMS that has been designated as overfished. The rebuilding measures would include status determination criteria that allow managers to determine whether overfishing was occurring and whether a particular stock was overfished. Other measures would address quotas and time periods to support stock rebuilding of North Atlantic swordfish and large coastal sharks; the limitation of access to shark and swordfish fisheries; observer coverage on charter and headboat vessels in the bluefin tuna purse seine and harpoon fisheries; drift gillnet use in the bluefin tuna fishery; school reserve measures in the bluefin tuna fishery; fishing year adjustment for Atlantic tunas; seasonal closure of the Florida Straits to pelagic longline fishing; quota monitoring procedures for Atlantic swordfish; education for pelagic longline vessel operators; vessel operator logbooks; the implementation of recommendations of the Atlantic Offshore Cetacean Take Reduction Plan relevant to pelagic longline vessels; the implementation of the Large Whale Take Reduction Plan; bycatch and bycatch mortality reduction for the recreational HMS fishery; retention based on fishing mortality expectations for shark species; catch and release requirements and requirements for coastal sharks; measures for the recreational fishery requiring that all sharks landed have heads, tails, and fins; the prohibition of finning of sharks; the dissolution of the shark operations team; quotas for pelagic, small coastal, porbeagle sharks; and dead discards of blue sharks; vessel permit and logbook requirements for charter and headboat vessels; registration requirements for all HMS tournaments; and new procedures for issuing experimental fishing permits for sharks. Measures for international cooperation and compliance in rebuilding of the fisheries would also be incorporated into the management plan. POSITIVE IMPACTS: The plan implementation would help prevent overfishing of the target HMS species, allowing overfished fisheries to be rebuild, while minimizing the economic impact of the management measures on the fishing and fish processing industry. The plan would also establish a foundation for international cooperation in HMS fishery management and for domestic cooperation in the management of HMS-related fisheries. Monitoring provisions would provide an information base for continued evaluation of fishery resources. NEGATIVE IMPACTS: Certain fishery management provisions, particularly quotas, area closure, and equipment restrictions, could result in economic losses to fishing interests.

Plumes characterized by high volatile/metal ratios, which has been hypothesized to be indicative of recent magmatism, were found between 17 degrees 22'S and 17 degrees 35'S in November-December 1993. Dives with the French submersible Nautile in December 1993 observed young sheet flows and widespread venting centered on the segment's shoalest point at 17 degrees 26'S. Eight submersible dives made one year later with the Japanese submersible Shinkai 6500 in September-November 1994 found glassy, unsedimented lavas, a range of diffuse and high-temperature vents, and several types of biologic communities on the ridge crest beneath the volatile-rich 1993 plumes. The diffuse vents range from small areas in the youngest lavas characterized by very low-temperature flow (<10 degrees C) and a relatively low macrofaunal diversity, to larger areas where the (apparent) older surface was covered with a dense and diverse biotope including anemones, tubeworms, mussels and serpulids. Several inactive vents marked by dead mussel/clam beds are present in the southernmost portion of the site in the older lavas. Submersible mapping indicates that the youngest lava (L0 unit) erupted for at least 4 km along the strike of the ridge at the southern site, and for 5-10 km at the northern site. The flow is up to 400 m in width at the southern site and may be as much as 1-2 km in width at the northern site. Comparison of the observed 1993 Fe/S, H (sub 2) S/heat, and (super 3) He/heat plume values with time series measurements at sites on the northern East Pacific Rise and the Juan de Fuca Ridge, where the onset of the magmatic event is known, implies that the last magmatic event at 17.5'S occurred within several years prior to 1993. Continued rapid cooling of the underlying heat source is implied from the significant diminishment in the light-scattering intensity and rise height of the overlying plumes recorded during 1994 submersible dives. The type and diversity of the vent biota found on the L0 vents also suggests a young system. The spatial and temporal scales of the accretion event at the 17.5 degrees S EPR site are similar in scale to eruptions on the intermediate-rate spreading North Cleft segment (Juan de Fuca Ridge) but the 17.5 degrees S event has more subtle gradients in the effusion rate of the eruptions and thermal and chemical character of the hydrothermal system.

The morphology of Sq is dependent on a number of factors, particularly latitude. Type curves that describe the latitudinal dependence of the horizontal and vertical components of Sq on a global scale appear in many texts. This paper first describes a recent compilation of global Sq curves for the total magnetic field, which is the component of most relevance to magnetic mapping. An analysis is then made of total-field variations from a north-south line of stationary recording magnetometers which operated across central Australia as part of the AWAGS experiment of 1989-1990. These data are analysed for information on the magnetic daily variation across the Australian continent, particularly its latitudinal variation. Observations cover a full year and their analysis is divided into four seasons to show variation with season as well as with latitude. The observed data show a minimum in the total-field signal in the geomagnetic latitude band 20 degrees -30 degrees , in support of the global Sq total-field curves. There is also clear evidence in the AWAGS data for the path of the Sq focus across Australia, identified by an amplitude minimum in the daily variation of the horizontal magnetic north component. The band in which the total-field Sq variations are generally reduced is termed the total-field "doldrums"; this band is on the equator-side of the path of the Sq focus.

Data presented in this paper show an inverse correlation between precipitation in the Sahel and the delta (super 18) O values of a coral skeletons of the species Siderastrea spp. collected from the island of Principe in the Gulf of Guinea. This is opposite to the correlation expected, as previous work has suggested that higher sea surface temperatures occur in the Gulf of Guinea during periods of low rainfall in the Sahel. Such an association would lead to a positive correlation between Sahel precipitation and skeletal delta (super 18) O. The explanation for the observed inverse correlation is that the salinity of the Gulf of Guinea is strongly influenced by the outflow from the Niger and Congo rivers. These periods of high freshwater input also correlate with periods of higher rainfall in the sub-Sahara and therefore affect the delta (super 18) O values of the coral skeleton. The correlation between delta (super 18) O values of the coral skeleton and temperature in the northern subtropical Atlantic Ocean (r= -0.34), the magnitude of the dipole (r= -0.45), and the latitudinal position of the intertropical convergence zone (r= -0.37) illustrate that the delta (super 18) O values in the coral skeleton reflect climate dynamics of the region that affect the precipitation patterns in sub-Sahara Africa.

The results show that the mid and upper level easterly jets play an important role in modulating rainfall variations over the Sahel. In particular, the lower tropospheric easterly jet is stronger during dry years whereas the upper level easterly jet is weaker. Moisture fluxes over West Africa during dry and wetter periods have also been studied, indicating that an important source of moisture for West Africa, is the southern Atlantic. The magnitude of the moisture flux in this region is greater during the wet episodes than during periods of droughts.

The precipitation estimates are primarily based on cold cloud top duration obtained from METEOSAT 6 data, and are refined using an optimal interpolation of observed precipitation, surface topography, and numerical model forecasts of wind and relative humidity. These precipitation estimates are produced operationally at the Climate Prediction Center (CPC) for the United States Agency for International Development (USAID), in support of the drought monitoring efforts for the African continent as a part of the Famine Early Warning System (FEWS) activity. The NCEP Climate Data Assimilation System (CDAS) analyses of atmospheric fields are used to determine the flow regimes for selected cases. The temporal and spatial variability of the model analyses for monthly periods are examined to determine the possible dynamic links with precipitation anomalies for the African continent. Extreme precipitation events during the 1997 ENSO event are examined to evaluate differences in circulation patterns.

Although both approaches have similar goals, they have fundamentally different scope and philosophy. Traditional single-species management deals with individual species under a "fix it when it breaks" philosophy. Ecosystem management deals with multiple species under a philosophy of preventing fisheries failures by maintaining natural ecosystem structure and function. An essential element of ecosystem management is the establishment of "no-take" marine reserves, areas where extractive activities are prohibited. These areas are needed to better understand ecosystem structure and function and to serve as reference areas for evaluating ecosystem performance and the impacts of fishing and other extractive human activities on the marine ecosystem. Expanded monitoring of populations, habitat, physical factors, and the human dimension is necessary to assess the dynamics, interactions, and performance of key ecosystem components.

Data were divided into two time strata, a pre-closure period (1982 -1991), and a regulated-by-closure period (1992-1996). I compared mean annual and mean monthly landings between periods. Headboat landings of mutton snapper were not significantly lowered by the enactment of regulations limiting harvest in May and June to the recreational bag limit. Commercial landings in May were significantly lower in May in the closure period, but June closure landings were slightly higher than the pre-closure period. Closure period July landings were significantly higher than in the pre-closure period. Trends in headboat CPUE mimic trends in effort. Headboat landings of greater amberjack were significantly greater in April (closed month), May and June in the pre-closure period than in the closure period. Commercial landings of greater amberjack were significantly lower in April in the closure period, while March landings were significantly greater and May landings were slightly greater than in the pre-closure period. Mean annual landings of both species were not significantly different between periods. The management action effectively reduced commercial fishing pressure on both species during the designated closed months. Annual harvest levels were not reduced, possibly due to increased landings in months adjacent to the closed months. Headboat landings, not expected to be affected by the regulations, were significantly lowered for greater amberjack but not for mutton snapper.

Indicative of a warming trend, total species composition of fishes had become more tropical, and a tropical sponge previously unrecorded at this latitude off the North Carolina coast became common. Two new (to the area) families and 29 new species of tropical fishes were recorded. Observations of 28 species of tropical reef fishes increased significantly. No new temperate species were observed, and the most abundant temperate species decreased by a factor of 22. Mean monthly bottom water temperatures in winter were 1-6 degree C warmer during the recent study. An increase in fish-cleaning symbiosis was especially noticeable.

High levels of Cu and Zn antagonize Mn nutrition by inhibiting cellular Mn uptake. Experiments were conducted to examine the interactive effects of Mn, the toxic metals Cu and Zn, and light on cellular Mn, chlorophyll a (Chl a), and specific growth rate in Thalassiosira pseudonana. Cu and Zn inhibition of growth rate occurred only at low Mn ion concentrations, an effect that was independent of light intensity and was totally accounted for by inhibition of Mn uptake by these metals. Cells grown at growth-limiting low light intensities contained high levels of Mn and Chl a, which are needed for the synthesis of additional photosynthetic units during low-light acclimation. This additional Mn was not provided by higher cellular Mn uptake rates, since these rates were the same in light-saturated and light-limited cells. However, because steady-state cell Mn is equal to the uptake rate divided by the specific growth rate, the cells were able to accumulate the additional Mn needed for acclimation once light limitation caused growth rate to decline, a inherent negative feedback relation. In seawater, Mn and Cu may interact with light in controlling algal growth rate, since the free ion concentration of both metals is influenced by light within the euphotic zone.

Several error sources are investigated and uncertainties in spatial rainfall rate variability and freezing level height are identified as the most significant. Spatial rainfall rate variability contributes to beam filling error, and beam filling error is investigated in detail by simulation of brightness temperatures resulting from rainfall rate fields with known spatial variabilities. The algorithm is used to estimate rainfall from the simulated brightness temperatures, and the estimation bias is calculated by comparison of the monthly rainfall estimates with the monthly rainfall used to simulate the brightness temperatures. The final result of the study is the mean monthly multiplicative bias error as a function of the freezing level height and the instantaneous rainfall rate variability.

The method suggests taking simultaneous and collocated reflectivity measurements at two radar wavelengths. Snowfall backscattering at one of these wavelengths should be in the Rayleigh regime or sufficiently close to this regime, while backscattering at the other wavelength should be substantially outside this regime for typical snowflake sizes. Combinations of K sub(a)-band (for a shorter wavelength) and X-, C-, or S-band (for a longer wavelength) radar measurements satisfy this requirement. The logarithmic difference between reflectivities at these two wavelengths provides an independent estimate of snowflake median size D sub(m), which exhibits a very low sensitivity to snowflake density and details of the size distribution. The estimates of D sub(m) and radar reflectivities Z sub(e) at the longer wavelength are then used to obtain snowfall rate R from the Z sub(e)-R-D sub(m) relationships, which have a snowflake effective density rho sub(e) as a "tuning" parameter. The independent information about snowflake characteristic size accounts for much of the improvement of the dual-wavelength method over traditional, single-parameter Z sub(e)-R relationships. The paper also presents experimental data collected during January-March 1996, near Boulder, Colorado, with the National Oceanic and Atmospheric Administration's K sub(a)- and X-band radars. The radar data were supplemented by simultaneous ground measurements of snow accumulation. Comparisons of the ground and dual-wavelength radar measurements indicate that a tuning value rho sub(e) of about 0.03-0.04 g cm super(-3) provides a good match with surface-observed snow accumulations. Differences in dual-wavelength radar estimates of accumulation for rho sub(e) between 0.03 and 0.04 g cm super(-3) are usually within 25%, while existing X-band, single-parameter Z sub(e)-R relationships yield accumulations that differ by as much as a factor of 4.

Estimates of standard random error for each month at each grid location are also provided in this data release. One of the primary intended uses of this dataset is the validation of climatic-scale precipitation fields that are produced by numerical models. Nearly coincident with this dataset development, the National Centers for Environmental Prediction and the National Center for Atmospheric Research have joined in a cooperative effort to reanalyze meteorological fields from the present back to the 1940s using a fixed state-of-the-art data assimilation system and large input database. In this paper, monthly accumulations of reanalysis precipitation are compared with the GPCP combined rain gauge-satellite dataset over the period 1988-95. A unique feature of this comparison is the use of standard error estimates that are contained in the GPCP combined dataset. These errors are incorporated into the comparison to provide more realistic assessments of the reanalysis model performance than could be attained by using only the mean fields. Variability on timescales from intraseasonal to interannual are examined between the GPCP and reanalysis precipitation. While the representation of large-scale features compares well between the two datasets, substantial differences are observed on regional scales. This result is not unexpected since present-day data assimilation systems are not designed to incorporate observations of precipitation. Furthermore, inferences of deficiencies in the reanalysis precipitation should not be projected to other fields in which observations have been assimilated directly into the reanalysis model.

In each of two seasons of high nekton abundance, fall (September 1993) and spring (May 1994), we took 100 quantitative samples using a 1-m super(2) drop sampler. We collected a total of 38 species of fishes and 19 species of decapod crustaceans. Vegetated habitats supported significantly higher densities of most numerically dominant species. Densities of total crustaceans, daggerblade grass shrimp Palaemonetes pugio, blue crabs Callinectes sapidus, and brackish grass shrimp Palaemonetes intermedius were significantly higher in salt marsh than seagrass. However, densities of total fishes, naked gobies Gobiosoma bosc, spotted seatrout Cynoscion nebulosus, pinfish Lagodon rhomboides, gulf pipefish Syngnathus scovelli, brown shrimp Farfantepenaeus aztecus (fall), white shrimp Litopenaeus setiferus, and pink shrimp Farfantepenaeus duorarum were not significantly different in salt marsh and seagrass. In spring, brown shrimp densities were higher in seagrass than salt marsh. In contrast to other abundant species, mean densities of bay anchovies Anchoa mitchilli were higher over nonvegetated bottom than in vegetated habitats in both seasons. Nekton size also differed among habitats, and organisms generally were smaller in seagrass beds than in marsh habitat. Our results provide further documentation that shallow vegetated habitats are important nurseries for many estuarine species. Furthermore, our study showed that where salt marsh and seagrass co-occur, most decapod crustaceans either selected for marsh habitat or showed no preference between these two vegetated habitats.

The spatial pattern of the mean and the phase of the annual cycle generally compare well, except that the amplitude of the annual cycle of model precipitation is much smaller than observed. On 10-30-day timescales, it is shown that averaging stations within a 5 degree radius is approximately equivalent to total wavenumber 20 (T20) spatial scale, although it is more important to have a high density of stations than an exact match of spatial scales. Ideally, there should be one station per 20 000 km super(2). On 10-30-day scales, observed rainfall is best correlated with OLR. Correlations between OLR and 150-mb divergence are larger than between observed rainfall and divergence or between rainfall and model precipitation. For example, if 10-30-day filtered OLR and divergence are truncated at T20 and rainfall is averaged to include stations within a 5 degree radius, OLR is correlated with rainfall at about -0.6, OLR is correlated with divergence at about -0.35, and rainfall is correlated with divergence at about 0.2. At least part of the lack of correlation is due to inadequate spatial sampling of rainfall. Correlations improve with larger spatial scale. The major seasonal transitions from dry to rainy regimes are captured well by OLR but not by the model quantities. The mean diurnal cycle is represented reasonably by 150-mb divergence.

A total of forty-four participants were included in the exercise, including NOAA, USEPA, state, Austrailian, Canadian, Mexican and Argentinean laboratories. Two samples were sent by NRC to each participant, a marine sediment collected on the east coast of Canada and a freeze-dried mussel tissue. Laboratories were also asked to analyse two certified reference materials (CRMs) MESS-2 and CRM 2976. 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 Tl 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.

N1 - Last updated - 2015-03-24 ER - TY - JOUR T1 - Simulating Flash Flood Events: Importance of the Subgrid Representation of Convection AN - 17028599; 4610899 AB - The Pennsylvania State University-NCAR Mesoscale Model is used to simulate six flash flood events that occurred in the central and eastern United States. Results suggest that standard model simulations of 24-h accumulated precipitation provide little indication of the potential for flash flood-producing rainfall for most events. Often the model generates convective outflow boundaries that rapidly move away from their source region and initiate new convection well removed from the original convective activity. This self-sustaining propagation mechanism prevents long-lived heavy rainfall over a particular region. Three modifications to the Kain-Fritsch convective parameterization scheme, each designed to test model sensitivity to the convective scheme formulation, are discussed. The modifications include maximizing the convective scheme precipitation efficiency and altering the scheme's treatment of convective downdrafts. Model results using the three modifications of the convective scheme each show improvements in 24-h precipitation totals compared to simulations generated using the unmodified convective scheme. Precipitation totals appear to be especially sensitive to the way downdrafts are treated within the convective scheme. In addition, the impact of including the mesoscale details of a previously generated outflow boundary into the model initial conditions is demonstrated for one of the flash flood cases. It is shown that including the surface mesoscale details can have a substantial impact upon the magnitude and location of model precipitation maxima.

AN - 16350548; 7126 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. An amendment to the FMP is thought to be needed in order to adjust fishing activities with respect to five species (red porgy, vermillion snapper, greater amberjack, gag grouper, and black sea bass). The proposed action as presented in this final supplement to the final EIS of August 1983 would include increasing the minimum size limit for recreational and commercial takes of red porgy, black sea bass, vermillion snapper, and gag grouper. It would also establish a daily recreational bag limit for red porgy, black sea bass, and great amberjack as well as an aggregate recreational bag limit for all snapper grouper species (which would include tilefish but exclude jewfish and Nassau grouper). Provisions for prohibitions of seasonal harvesting in excess of bag limits and the possession, purchase, or sale would also be established. Escape vents and escape panels with degradable fasteners would be required in black sea bass pots. Commercial trip limits and landing quotas would be established for greater amberjack. Vessels with longline gear aboard would be allowed to possess only snowy grouper, warsaw grouper, yellowedge grouper, misty grouper, golden tilefish, blueline tilefish, and sand tilefish. 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 restrictions on landings would create short-term economic hardships for some commercial operators. Commercial fishing interests would experience declines in gross annual revenue for all five target species, and equipment provisions would require additional investment. The recreational bag limits would further limit recreational use of the fishery for some species.

AN - 16348940; 7119 AB - PURPOSE: The implementation of a management plan for the Atlantic spiny dogfish fishery for the U.S. Exclusive Economic Zone is proposed. Spiny dogfish, which are a common small shark species, are a migratory species that range from Labrador to Florida, but are most abundant from Nova Scotia to Cape Hatteras. The species is considered a unit stock in the Northwest Atlantic Ocean. With the decline of more traditional groundfish resources in recent years, an increase in directed fishing for spiny dogfish has resulted in a nearly six-fold increase in landings in the last seven years. The lack of any regulations pertaining to the harvest of this species led the Mid-Atlantic and New England Fishery Management Councils to development a management plan for the species. The most recent stock assessment indicates that the total adult spiny dogfish stock biomass is currently approximately 280 million pounds, a figure well below the stock biomass target of 440 million pounds. Alternatives considered in this draft EIS include a No Action Alternative, the preferred alternative, alternative rebuilding schedules, a commercial quota with trip limits, a commercial quota with alternative seasonal allocations, a commercial quota with alternative size limits including a slot size limit, a limited entry program for the commercial fishery, and a target commercial quota. The preferred alternative, designed to restore the biomass to the biomass target, would introduce the following measures to conserve the resource: permit and reporting requirements for commercial vessels, operators, and dealers; the establishment of a spiny dogfish monitoring committee; the implementation of a framework adjustment process; the implementation of a 10-year stock rebuilding schedule; the institution of a commercial quota; the seasonal (semi-annual) allocation of the quota; a prohibition of finning; and a limit of 80 nets (50 fathoms each) in the spiny dogfish gillnet fishery. The fishing year for spiny dogfish would be established as the 12-month period beginning May 1st. The plan involves two phases designed to reduce fishing mortality rate. The first phase would allow for a one-year exit fishery of 22 million pounds to allow a phase out of the directed fishery. This approach was chosen to minimize the impact of the rebuilding program on both the harvesting and processing sectors of the industry. For the first year of the rebuilding plan (1999-2000), fishing mortality would be reduced to 0.2 . During the remaining nine years of the plan, fishing mortality (2000-2009), fish mortality would be reduced to 0.03. This schedule would allow for stock rebuilding to a level that would support harvests at or near the stock size that would maximize average recruitment (440 million pounds) in the year 2009. POSITIVE IMPACTS: The plan implementation would help reduce fishing mortality to ensure that overfishing does not occur, promote compatible management regulations between state and Council jurisdictions and the U.S. and Canada, and manage the fishery to minimize regulations with respect to the target fishery and other fisheries. NEGATIVE IMPACTS: The regulation of the fishery would place economic pressure on some fishing industry operators and processors.

These measurements are often collected and analyzed using infrared detectors. Laboratory data are presented here which suggest that errors of the order of several parts per million in xCO (sub 2) can result if the analyzer temperature and pressure are not carefully matched during calibration and sampling. Field data were examined to address questions about the importance of measuring analysis temperature and pressure under more extreme conditions, sample averaging, and calibration frequency. The results indicate that calibration frequency can be minimized without significant compromises in data quality if the analyzer temperatures and pressures are suitably monitored and/or controlled. Daily calibrations gave results to within 0.4 ppm of the results obtained by hourly calibration when the temperature of the analyzer was controlled to + or -0.2 degrees C and the voltages were corrected for pressure differences between calibration and sampling. copyright 1998 Elsevier Science B.V.

We measured C and N elemental compositions, geolipid concentrations, and delta (super 13) C values for bulk organic material and individual alkanes in samples taken from a 40-cm sediment core from the eastern basin of Lake Erie to infer recent trends in primary productivity and diagenesis. The predominance of autochthonous algal-derived C throughout the core is evidenced by low C/N values (9-10) and the persistent abundance of n-C (sub 15) to n-C (sub 17) alkanes throughout the core. The delta (super 13) C values of bulk organic C from Lake Erie vary between -25.9 and -24.9 per mil with a maximum corresponding to the period of elevated historical P loading. Within Lake Erie, delta (super 13) C values of short-chained algal-derived alkanes (n-C (sub 25) ). Down-core variations in the delta (super 13) C composition of algal-derived short-chained alkanes do not exhibit the same trend as that observed for bulk organic C. Down-core variation in delta (super 13) C values of individual alkanes likely reflect multiple diagenetic effects including kinetic fractionation effects, variations in the relative contributions of isotopically unique n-alkanes to the sediments, and/or temporal changes in (super 13) C enrichments of n-alkanes associated with a single source. High sedimentation rates characteristic of this core emphasize temporal variations in molecular delta (super 13) C values that might not otherwise be observed. Whereas delta (super 13) C data for bulk sedimentary organic C appear to reflect variation in trophic state, the isotopic record for algal-derived n-alkanes (e.g., n-C (sub 17) and pristane) from Lake Erie must be considered from the perspective of molecular transformations.

It is nuclear whether this pattern is due to rapid lineage sorting accelerated by sweepstakes recruitment, historical bottlenecks in population size, founder events, or natural selection, any of which could retard the accumulation of deep mtDNA lineages. Recent advances in paleoclimate research prompt a reexamination of oceanographic processes as a fundamental influence on genetic diversity; evidence from ice cores and anaerobic marine sediments document strong regime shifts in the world's oceans in concert with periodic climatic changes. These changes in sea surface temperatures, current pathways, upwelling intensities, and retention eddies are likely harbingers of severe fluctuations in population size or regional extinctions. Sardines (Sardina, Sardinops) and anchovies (Engraulis) are used to assess the consequences of such oceanographic processes on marine fish intrageneric gene genealogies. Representatives of these two groups occur in temperate boundary currents on a global scale, and these regional populations are known to fluctuate markedly. Biogeographic and genetic data indicate that Sardinops has persisted for at least 20 million years, yet the mtDNA genealogy for this group coalesces in less than half a million years and points to a recent founding of populations around the rim of the Indian-Pacific Ocean. Phylogeographic analysis of Old World anchovies reveals a Pleistocene dispersal from the Pacific to the Atlantic, almost certainly via southern Africa, followed by a very recent recolonization from Europe to southern Africa. These results demonstrate that regional populations of sardines and anchovies are subject to periodic extinctions and recolonizations. Such climate-associated dynamics may explain the low levels of nucleotide diversity and the shallow coalescence of mtDNA genealogies. If these findings apply generally to marine fishes, management strategies should incorporate the idea that even extremely abundant populations may be relatively fragile on ecological and evolutionary time scales.

The study was conducted in a laboratory using tailings from the proposed AJ mine. Although plans to reopen the AJ mine were canceled in January 1997, STD remains a future option for some coastal mines in Alaska (Coldwell and Gensler 1993). Results from this study will provide resource managers with valuable information on the potential effects of STD on a dominant benthic invertebrate which supports important commercial and recreational fisheries.

Decreased incidence of hepatic inflammatory cells as a function of total polynuclear aromatic hydrocarbon (TPAH) concentration was evidence for immunosuppression in exposed fish, and decreased immune surveillance is a possible mechanism by which subclinical VHSV could be reactivated. Adult Pacific herring of unknown status regarding infection by VHSV were captured from the wild and exposed to weathered crude oil for 16-18 days. TPAH concentration in tissue, VHSV prevalence, and mortality were correlated with dose. Histopathologic lesions were significantly correlated with TPAH concentration and prevalence of VHSV, but not gender or length. Significant lesions included increased hepatocellular necrosis, splenic thrombosis, and decreased inflammation in the liver.

Although sediments in many urbanized estuaries contain high concentrations of contaminants, there is little evidence linking a specific organic or inorganic chemical to a particular liver lesion in winter flounder (Pleuronectes americanus), despite increasing study in recent years. Between 1984 and 1986, sediments and winter flounder were collected from 10 sites in the north-east United States ranging from grossly polluted to relatively unimpacted. Sediments were analysed for polycyclic aromatic hydrocarbons (PAHs), chlorinated pesticides, polychlorinated biphenyls (PCBs), and metals. Gross and microscopic pathological examinations were conducted on winter flounder liver sections. Factor and canonical correlation analyses were used to explore associations between biological and chemical measurements. Hepatitis, cholangitis, phlebitis, and macrophage aggregate hyperplasia showed positive associations with low molecular weight, petroleum-derived PAHs (naphthalene, anthracene, 1-methylnaphthalene, 2-methylnaphthalene, 2,6-dimethylnaphthalene, acenaphthene, phenanthrene, biphenyl, fluorene, and 1-methylphenanthrene), the pesticides lindane, hexachlorobenzene, heptachlor epoxide, and o,p'-DDD, tri- to hexachlorobiphenyls, and chromium, cadmium, lead, thallium, and selenium, but were negatively associated with the pesticides o,p'-DDT, p,p'-DDT, p,p'-DDE, and mirex. Cytoplasmic hepatocellular vacuolation, cytoplasmic bile duct vacuolation, neoplasms, and pre-neoplasms showed positive associations with most PAHs measured, whether petroleum-derived or combustion-derived (benzo[a]pyrene, benzo[e]pyrene, benzo[a]anthracene, dibenzo[a,h]anthracene, perylene, chrysene, and fluoranthene), the pesticides dieldrin, trans-nonachlor and alpha-chlordane, and silver, copper, antimony, and tin, but no associations with PCBs were found. Coagulative necrosis, single cell necrosis and haemorrhagic necrosis showed positive associations with hepta- to nonachlorobiphenyls and arsenic, zinc, nickel, and mercury, and negative associations with high molecular weight, combustion-derived PAHs and DDT compounds and metabolites.

The focus is on the atmospheric conditions over the conterminous United States relative to wet and dry monsoons over the southwestern United States. The onset of the monsoon in this region, which typically begins in early July, is determined using an index based on daily observed precipitation for a 32-yr (1963-94) period. Composites of observed precipitation and various fields from the National Centers for Environmental Prediction-National Center for Atmospheric Research Reanalysis for wet and dry monsoons are used to show that the interannual variability of the summer precipitation regime closely mimics the seasonal changes associated with the development of the North American monsoon system. The warm season precipitation regime is characterized by a continental-scale precipitation pattern consisting of an out-of-phase relationship between the Southwest and the Great Plains/Northern Tier and an in-phase relationship between the Southwest and the East Coast. This pattern is preserved for both wet and dry monsoons, but the Southwest is relatively wetter and the Great Plains are relatively drier during wet monsoons. Wet (dry) monsoons are also associated with a stronger (weaker) upper-tropospheric monsoon anticyclone over the western United States, consistent with changes in the upper-tropospheric divergence, midtropospheric vertical motion, and precipitation patterns. The intensity of the monsoon anticyclone over the western United States appears to be one of the most fundamental controls on summertime precipitation downstream over the Great Plains. Evidence is presented that the interannual variability of the U.S. warm season precipitation regime is linked to the season-to-reason "memory" of the coupled atmosphere-ocean system over the eastern tropical Pacific. In particular, it is shown that SST anomalies in the eastern Pacific cold tongue and precipitation anomalies in the intertropical convergence zone, present during the winter and spring preceding the monsoon, are linked via an anomalous local Hadley circulation to the warm season precipitation regime over the United States and Mexico. Wet (dry) summer monsoons tend to follow winters characterized by dry (wet) conditions in the Southwest and wet (dry) conditions in the Pacific Northwest. This association is attributed, in part to the memory imparted to the atmosphere by the accompanying Pacific SST anomalies.

It is found that during this period the April-June (AMJ) seasonal-mean anomaly was not representative of the variability of 10-day low-pass anomalies. Rather, over North America large fluctuations on monthly and shorter timescales occurred, with the dominant streamfunction anomalies not strongly anticyclonic until June. In fact, the AMJ anomaly was dominated by two episodes of rapidly developing, intense anomalous anticyclones in early and late June. Examination of the daily 10-day low-pass streamfunction anomalies at 300 mb suggests that propagating Rossby waves originating in the west Pacific played a dominant role in the initiation of these intense anomalous anticyclones. Numerical experiments with a linear, time-dependent, barotropic model also support this hypothesis. These results suggest that the AMJ anomaly, which has been characterized as a wave train seemingly forced in the east Pacific, may not provide a useful picture of the circulation associated with the drought. Instead, the drought may be better studied not as a single seasonal event, but rather as a succession of events that together produced a serious hydrological deficit.

The available data consist of specific differential phase K sub(DP), differential reflectivity Z sub(DR), cross-correlation coefficient rho sub(hv), and radar reflectivity factor Z. These data were obtained with the 10-cm-wavelength Cimarron polarimetric weather radar. The data suggest that in pure snow the average values of K sub(DP), and Z sub(DR) do not follow a systematic trend with change of the radar reflectivity factor if Z < 35 dBZ; this is not the case in rain. Precipitation is qualified as snow if the average Z sub(DR) is less than 0.2 dB for Z < 35 dBZ. The presence of a bright band with a pronounced rho sub(hv), minimum and Z sub(DR) maximum is a good discernible feature for discriminating between snow and rain. Thus, a localized deep minimum of the cross-correlation coefficient delineates the transition region between snow and rain in the horizontal direction if sufficiently large snowflakes are generated in the transition area. Otherwise, a sharp change of Z sub(DR) can be used to localize the position of the snow-rain line.

AN - 17150608; 4444592 AB - Recently, Allendorf et al. (1997) proposed criteria intended to guide prioritization of Pacific salmon (Oncorhynchus spp.) stocks for conservation. The authors provide a good summary of several important aspects of extinction risk, and we agree with many of their points. We don't believe, however, that their prioritization method is entirely workable, and we are concerned that their criteria ignore some major conservation issues for Pacific salmon. We are also concerned that, no doubt unintentionally, their paper gives the mistaken impression that evaluating risk for salmon populations is a straightforward process.

The predictive abilities and recommended applications of two sets of guidelines, ERLs/ERMs and TELs/PELs, are discussed in this paper. The SQGs were intended as informal (i.e., non-regulatory) benchmarks to aid in the interpretation of chemical data. Low-range values (i.e., ERLs or TELs) were intended as concentrations below which adverse effects upon sediment-dwelling fauna would be expected only infrequently. In contrast, the ERMs and PELs represent chemical concentrations above which adverse effects are likely to occur. Evaluations of the reliability and predictive ability of the SQGs indicate they can be used effectively to assess the quality of soft, aqueous, sedimentary deposits. Specifically, the SQGs can be used to classify sediment samples with regard to their potential for toxicity, to identify contaminants of concern, and to prioritize areas of concern based on the frequency and degree to which guidelines are exceeded. Toxicity and bioaccumulation tests, toxicity identification evaluations, and benthic community assessments provide complimentary information for assessing sediment quality.

Settlement of larval conch within the system was associated with the specific location of the nursery and positively correlated with subsequent recruitment to the juvenile population (200/m super(2)), and the crabs probably represent an important source of mortality for small conch in the primary nursery ground. Shells of dead conch indicated that molluscan and asteroid predators probably caused most of the predatory mortality on young conch that settled outside the nursery. Because critical settlement and recruitment habitats for queen conch are associated with particular hydrographic conditions, these habitats cannot be identified or predicted simply by mapping obvious features such as seagrass cover, depth, or sediment type. An understanding of dynamic processes, such as larval transport and retention, selective settlement mechanisms, and trophic ecology, will be required to identify critical nursery habitats.

In Alaska waters, shortraker rockfish, S. borealis, and rougheye rockfish, S. aleutianus, are especially prized. Both species reside in offshore waters of the upper continental slope, and they often co-occur. Knowledge of stock structure and the degree of mixing among populations is important for the rational management of commercially important marine species. At present, such information is lacking for shortraker and rougheye rockfish, and questions, such as whether these species perform lengthy migrations or whether discrete populations exist, are unanswered. Traditional tag-and-release experiments are not feasible for physoclistic fish such as rockfish because they cannot survive the barotrauma of initial capture. One alternative to human-implanted tags is the use of parasites as naturally occurring tags. Because necropsies of rockfishes are time consuming, we examined 100 fish of each species from the GOA to identify the feasibility of targeting selected parasites as tags for these species.

Spatial and ontogenetic variation in otolith elemental composition was examined to make inferences about the stock structure of these species. Stepwise canonical discriminant analyses of the concentrations of barium, potassium, magnesium, manganese, sodium, phosphorus, sulphur, and strontium were used to differentiate groups of fish. These analyses identified an optimum grouping of at least two stocks of school mackerel and a single stock of spotted mackerel in the study region, although our results showed that the most informative comparisons were made among fish of the same year class. The age of fish in collected samples produced strongly significant effects on mean elemental composition of otoliths. These patterns offered independent support for hypotheses about stock structure from previous tagging, catch monitoring, ageing, and reproductive studies. Discrimination between school and spotted mackerel stocks will enable the species to be managed on the basis of stock structure throughout their east coast distribution.

The larger of the two species is the pink snailfish (C. furcellus); the smaller species is an undescribed species referred to as the red snailfish. According to 1982 trawl survey data, incidence of snailfish eggs and larvae within crab branchial chambers increases with carapace length (CL) and is greater for male than female crabs. A logistic model fitted to the incidence data predicts that a 140-mm-CL male will have an incidence of 0.52, approximately 1.9 times greater than the incidence for a 100-mm male. Incidence for a 100-mm-CL male is approximately 1.9 times greater than that for a female of equal size. On the basis of developmental stages of embryos carried by female golden king crab and the developmental stages of snailfish embryos within a female's branchial chambers, snailfish appear to deposit eggs preferentially in crabs that are early in their molt cycle. The presence of the egg masses results in gill compression, localized necrosis of gill tissue and, in extreme cases, total loss of gill tissue on one side of the body. For crabs of commercial size, the presence of eggs and larvae increases mortality within the holds of fishing vessels by 35%. The current incidence of eggs and larvae in commercial sized males, however, is so low that the effect on the commercial fishery is considered to be small.

Only juvenile animals appeared to be present in nearshore waters of the study area during winter. Of the 40 specimens for which cause of death was clearly established, 25 showed evidence of entanglement in fishing gear. The bycatch and mortality of these porpoises in offshore gillnet fisheries in the Mid-Atlantic points to the need for a directed observer program.

AN - 16347433; 7107 AB - PURPOSE: The implementation of land acquisition, sustained yield, and habitat conservation plans in relation to timber harvest activities in northern California is proposed. The Pacific Lumber Company and its subsidiaries (PALCO) manages 211,00 acres of forest lands in Humboldt County, including 5,625 acres of lands to be acquired under the Headwaters Agreement. The lands are used for timber harvesting, grazing, agricultural and residential purposes. The Headwaters lands and 9,468 acres of land now operated by the Elk River Timber Company are addressed. Four alternatives, including the No Action Alternative (Alternative 1) and one subalternative, are considered in this draft EIS. Under the proposed action (Alternative 2), approximately 1,764 acres would be added to the Headwaters purchase area to buffer the old-growth redwood on the PALCO portion; the remaining 7,704 acres would be transferred to PALCO as partial payment for the Headwaters. The Headwaters and other areas of PALCO land provide important habitat for a number of endangered or threatened species, including marbled murrelet, a seabird that nests in old-growth trees, the northern spotted owl, and the coho salmon. PALCO wishes to obtain incidental take permits (ITPs) from the U.S. Fish and Wildlife Service for take of marbled murrelet and other wildlife and resident fish and from the National Marine Fisheries Service for salmon and steelhead trout. To obtain an ITP, PALCO must prepare a habitat conservation plan that, among other things, minimizes and mitigates take and avoids jeopardizing the relevant species. The California Department of Fish and Game also reviews the conservation measures of the HCP that relate to state-listed species and other relevant species. Activities covered by the habitat conservation plan and the associated ITPs would include timber management, near-stream gravel mining, commercial rock quarrying, grazing, stream enhancement projects, operation of fish-rearing facilities, scientific surveys and studies, recreational resources management, and road and landing construction, maintenance, and closure. The conservation strategies would address old-growth redwood, aquatic species, and silvicultural practices. POSITIVE IMPACTS: In addition to generating substantial timber to support the local and regional economies, the action alternatives would ensure the maximum possible protection and perpetuation of endangered species and other natural resources. Sediment delivered to streams by the affected lands would decline, and wetland and riparian land, fish habitat, and remaining old-growth, including redwood and Douglas-fir, within the area would benefit from additional protection. NEGATIVE IMPACTS: Under the proposed action, timber harvesting and other activities would generate particulate matter, and winter road construction and wet-weather use of roads would result in some stream turbidity. Old growth in southern Humboldt County would decline by 3.2 percent, reducing habitat for the affected endangered species and other old-growth-dependent species. Late seral habitat would decline more under the proposed action than under any other alternative.

AN - 36412096; 7097 AB - PURPOSE: The amending of the total allowable catch for groundfish in the Bering Sea/Aleutian Islands and Gulf of Alaska is proposed. The plan applies to all foreign and domestic fishing vessels operating in the U.S. Exclusive Economic Zone (EEZ) off Alaska. More specifically, the plan applies to the EEZ in relation to the Bering Sea and the Aleutian Islands Area and the Gulf of Alaska. The fishery resources within the areas includes walleye pollock, Pacific cod, flathead sole, rock sole, Greenland turbot, yellowfin sole, arrowtooth flounder, other flatfish, sablefish, rockfish, Atka mackerel, squid, and forage fish. The fisheries are managed via a myriad of interrelated regulations covering total allowable catches (TACs) for target species, time and area closures, gear restrictions, bycatch limits for prohibited species (including marine mammals and certain shellfish), and allocation of TACs among vessels delivering to different types of processor groups, gear types, and qualifying communities. The fisheries are promulgated every year with new TACs. The new TACs are re-determined annually based on scientific appraisal of the biological status of the stocks and appropriate application of fishery management principles. This draft supplement to the final EISs of 1979 and 1981 analyzes the impacts of fishing over a range of TAC specifications, compares them to impacts of status quo fishing, and considers four alternative TAC regimes, including the status quo (No Action Alternative, Alternative 1). Under the status quo, which is the preferred alternative, TACs would continue to be set by species or species groups for each groundfish complex, and the sum of the TACs of the component species would have to remain within the optimum yield (OY) range of the complex. The OY range for the Bering Sea/Aleutian Islands groundfish complex is 1.4 to 2.0 million metric toms (mt), and that for the Gulf of Alaska is 116,000 to 800,000 mt. Under this alternative, TAC projections would be made from 1999 through 2002 for the purpose of demonstrating potential fishery impacts. In actuality, re-setting of TACs each year would be based upon the status of the stocks current for that year. POSITIVE IMPACTS: The ex-vessel value of groundfish catch would be higher for the Bering Sea/Aleutian Islands area under the status quo alternative than for other alternatives. NEGATIVE IMPACTS: The ex-vessel value of groundfish catch would be substantially lower for the Gulf of Alaska under the status quo alternative than for one of the other alternatives. LEGAL MANDATES: Fishery Conservation and Management Act of 1976 (16 U.S.C. 1801).

A highly conserved alpha -helix in the C-terminal regulatory domain of the tetrameric enzyme was previously implicated in effector binding and feedback inhibition. Double (447, 451) and triple (447, 451, 454) alanine replacements for the conserved amino acids leucine 447, leucine 451, and leucine 454 in this region yield enzyme variants that show increased sigmoidality in steady-state kinetics, and which are less sensitive to the allosteric modifiers isoleucine and valine. Equilibrium binding studies using fluorescence, enzyme kinetic, and calorimetric approaches indicate that the enzyme variants possess reduced affinity for isoleucine and valine, and suggest that heterotropic ligands can bind to the same site to promote their different effects. The increase in sigmoidal kinetics for the mutants relative to wild-type threonine deaminase may be attributable to the elimination of L-threonine binding to the effector sites, which activates the wild-type enzyme. Enzyme kinetic data and isotherms for active site ligand binding to the mutants can be analyzed in terms of a simple two-state model to yield values for allosteric parameters that are consistent with previous estimates based on an expanded two-state model for homotropic cooperativity for threonine deaminase.

The applicability of this technique to numerous environmental and dietary matrices is illustrated by analysis of a range of certified reference materials (CRMs) and a powdered grass material that was prepared as an in-house reference material (RM). Because of the combustion step involved, samples with low or no fat content (e.g., cereal products, selected botanical specimens, and nonfat milk powder) and inorganic materials (e.g., coal fly ash and dried sediments) are more suited for analysis by this method. In general, the results for several types of samples obtained by this method agreed with those obtained by a second radiochemical (R) NAA, as well as by a third method using inductively coupled plasma mass spectrometry (ICP-MS). PC-NAA is a useful technique for determining iodine in biological and environmental samples, especially for verification of iodine results obtained from other methods.

The performance of these structures in selected earthquakes and hurricanes is summarized. In general, wood-frame houses performed well with relatively few instances of structural failures and without serious loss of lives. The review of experimental research covers studies on full-scale houses, shear walls and intercomponent connections. The development of analytical procedures to predict component and structural behavior under different types of loading is also presented. It is found that while significant progress has been made in recent years in analytical modeling of shear walls and horizontal diaphragms, only limited progress has been made on the modeling of a complete house and intercomponent connections. Based on this review, a multi-year research program is proposed to determine the baseline performance of single-family houses.

Sediments from each site yielded abundant fish bones and otoliths and squid beaks that represent prey remains deposited by penguins during the nesting period. Radiocarbon analyses indicate that colony occupation began prior to the Little Ice Age (LIA; 1500-1850), with the oldest site dating to 644 yrs before present. Food remains indicate that the non-euphausiid prey of penguins consisted primarily of a mesopelagic squid (Psychroteuthis glacialis) and 2 species of fish (Pleuragramma antarcticum and Electrona antarctica). The relative abundance of the first 2 prey taxa varied significantly among 6 sites, with colonies dating prior to the LIA having greater representation of squid, and less of silverfish, than those occupied during the LIA. Data from control excavations at 3 modern colonies indicate a diet similar to that of the pre-LIA sites. (Auth. mod.)

The method consists of calculating the ratio of areally weighted precipitation to precipitation at individual grid cells in the basin during period when station density is high. The ratios are used in conjunction with data collected during the late 19th and early 20th centuries to generate improved basin precipitation estimates. The 'ratio method' provides precipitation estimates for that period that are more in agreement (relative to the Thiessen method) with trends in flow for the outlet of Lake Superior.

Program goals were to evaluate the effectiveness of the Utah operational cloud seeding program and to recommend improvements. Sophisticated numerical modeling was used in conjunction with the observational programs. Amounts and distributions of SLW (supercooled liquid water) cloud were investigated, as was transport and dispersion of ground-released seeding agents and tracer gases. Several experiments directly monitored ice crystals and snowfall rates resulting from either silver iodide (AgI) or liquid propane seeding. Results showed frequent SLW in excess of natural convesion to snowfall, suggesting significant seeding potential. The SLW was concentrated near the terrain where temperatures were relatively warm. When valley-released AgI was transported to cloud levels, resulting ice crystal formation was usually too limited for significant snowfall augmentation. However, marked enhancement of ice crystal concentrations and snowfall rates resulted from a number of high altitute releases of both AgI and liquid propane. Propane seeding was effective within even slightly supercooled clouds. Several recommendations were given for improving the operational seeding programs effectiveness.

This network is itself actually an enhanced framework of seven Coastal-Marine Automated Network (C-MAN) stations for long-term monitoring of meteorological parameters (wind speed, wind gusts, air temperature, barometric pressure, relative humidity). To the C-MAN network SEAKEYS adds oceanographic parameters (sea temperature, photosynthetically active radiation, salinity, fluorometry, optical density) to the stations. As a recent enhancement to the SEAKEYS network, an expert system shell is being employed to provide daily interpretations of near real-time acquired data for the benefit of scientists, fishermen and skin divers. These interpretations are designed to be automatically emailed to Sanctuary managers and to the FIO maintainers of the network. The first set of interpretations include those dealing with environmental conditions conducive to coral bleaching. Other marine environmental interpretations will be forthcoming.

Theory and Experiments AN - 17438256; 4655814 AB - We present a detailed atomic level view of the interactions between cytochrome P450cam (CYP101) and its natural redox partner, putidaredoxin (Pdx). A combined theoretical (Poisson-Boltzmann electrostatic calculations, electron transfer pathways, and molecular dynamics) and experimental (site-directed mutagenesis and kinetic analysis) study is used to pinpoint surface residues in both proteins that are important for electron transfer, binding, or both. We find a situation where the electrostatically complementary regions at the surface of both proteins overlap strongly with regions that have large electron transfer couplings to the redox centers. This means that a small surface patch in each protein is involved in binding and electron transfer. A dominant electron transfer pathway is identified, corresponding to an electron leaving the reduced Fe sub(2)S sub(2) in Pdx, going through Cys39 and Asp38, and transferring across the interprotein interface to Arg112 (CYP101), then to a heme propionate group, and finally to the heme iron center.

High levels of ionic Cu super(2+) and Zn super(2+) inhibited cellular Mn uptake, and high Cu super(2+) inhibited Zn uptake rates. These effects were associated with growth rate inhibition at combined conditions of high Zn super(2+) and low Mn super(2+) and at high Cu super(2+) and low Zn super(2+). Zinc inhibited Mn uptake by competitively blocking Mn binding to a high-affinity Mn uptake system which was under negative feedback regulation. Kinetic modeling suggested that Zn was taken up by this system, and as a result, cellular Zn concentrations increased as external Mn super(2+) was decreased. Zinc uptake behavior was complex, and in addition to the Mn system, uptake appeared to involve a high-affinity Zn system induced at low Zn super(2+) and a separate constitutive low-affinity system. High Cu super(2+) levels inhibited zinc uptake by the high-affinity transport system. Such complex competitive interactions among metals provide important controls on cellular metal accumulation, toxicity, and nutrition.

When combined with water intake records and wave measurements our observations show that local resuspension is not responsible for maintaining the benthic nepheloid layer (BNL) during the stratified period. Resuspension of bottom material by surface wind waves occurs in shallow water (13 m), but this material is not transported offshore into the BNL during downwelling events. During upwellings material may be transported onshore from the BNL into shallow water, but additional material is required to produce the concentrations observed at the inner stations. Resuspension by internal waves may be the source of this additional material. Changes in the vertical structure of the benthic nepheloid layer appear to account for most of the changes in suspended particulate material at the two offshore stations. These changes are probably due to a combination of internal wave action and regional changes in current patterns.

Snow and ice analysts in the National Environmental Satellite, Data, and Information Service have been creating weekly maps showing the extent of snow cover for the Northern Hemisphere since 1966 using visible imagery from polar-orbiting and geostationary satellites and surface observations as data sources. The current process is mostly manual and time-consuming, taking up to 10 hours to produce a map during the snow season. Where cloud cover precludes an unobstructed view of an area during the entire week, the analysis from the previous week is carried forward. Each week the analyst draws a new map by hand, then digitizes the extent of snow and ice cover using an 89 x 89 line grid overlaid on a stereographic map of the Northern Hemisphere. The hand-drawn map is photocopied and distributed and the digitized map is saved to a file for use in National Weather Service numerical models and for archival storage. IMS was designed and built to replace and improve this process by producing a more accurate and timely product.

The technique, called the auto-estimator, runs in real time for applications to flash flood forecasting, numerical modeling, and operational hydrology. The auto-estimator uses the Geoestationary Operational Environmental Satellite-8 and -9 in the infrared (IR) 10.7-mm band to compute real-time precipitation amounts based on a power-law regression algorithm. This regression is derived from a statistical analysis between surface radar-derived instantaneous rainfall estimates and satellite-derived IR cloud-top temperatures collocated in time and space. The rainfall rate estimates are adjusted for different moisture regimes using the most recent fields of precipitable water and relative humidity generated by the National Centers for Environmental Prediction Eta Model. In addition, a mask is computed to restrict rain to regions satisfying two criteria: (a) the growth rate of the cloud as a function of the temperature change of the cloud tops in two consecutive IR images must be positive, and (b) the spatial gradients of the cloud-top temperature field must show distinct and isolated cold cores in the cloud-top surface. Both the growth rate and the gradient corrections are useful for locating heavy precipitation cores. The auto-estimator has been used experimentally for almost 3 yr to provide real-time instantaneous rainfall rate estimates, average hourly estimates, and 3-, 6-, and 24-h accumulations over the conterminous 48 United States and nearby ocean areas. The NOAA/NESDIS Satellite Analyses Branch (SAB) has examined the accuracy of the rainfall estimates daily for a variety of storm systems. They have determined that the algorithm produces useful 1-6-h estimates for flash flood monitoring but exaggerates the area of precipitation causing overestimation of 24-h rainfall total associated with slow-moving, cold-topped mesoscale convective systems. The SAB analyses have also shown a tendency for underestimation of rainfall rates in warm-top stratiform cloud systems. Until further improvements, the use of this technique for stratiform events should be considered with caution. The authors validate the hourly rainfall rates of the auto-estimator using gauge-adjusted radar precipitation products (with radar bias removed) in three distinct cases. Results show that the auto-estimator has modest skill at 1-h time resolution for a spatial resolution of 12 km. Results improve with larger grid sizes (48 by 48 km or larger).

Satellite measurements offer a possible way to fill in the data voids and obtain a complete map of surface temperature over the entire globe. A method has been developed to calculate near-surface temperature using measurements from the Special Sensor Microwave/Imager (SSM/I). To accomplish this, the authors identify numerous surface types and make dynamic adjustments for variations in emissivity. Training datasets were used to define the relationship between the seven SSM/I channels and the near-surface temperature. For instance, liquid water on the surface reduces emissivity; therefore, the authors developed an adjustment to correct for this reduction. Other surface types (e.g., snow, ice, and deserts) as well as precipitation are identified, and numerous adjustments and/or filters were developed for these features. The article presents the results obtained from training datasets, as well as an independent case study, containing extreme conditions for deriving temperature from the SSM/I. The U.S. networks of first-order and cooperative stations, quality controlled by NCDC, serve as validation data. The correlation between satellite-derived and in situ temperatures during the independent case ("Blizzard of 1996") was greater than 0.95, and the standard error was 2 degree C. The authors also present SSM/I-derived snow cover and wetness maps from this 2-week period of the blizzard. A prototype for blending the satellite and in situ measurements into a single land surface temperature product is also presented.

Circulation patterns associated with precipitation regimes are described and physical mechanisms are proposed. Contributions from intraseasonal and interannual bands are examined. When enhanced convection is located in the western Pacific, dry conditions in the Southwest (SW) and wet conditions in the Pacific Northwest (PNW) are observed. Fluctuations in both intraseasonal and interannual bands contribute to the rainfall variability. Enhanced convection in the western Pacific is accompanied by suppressed convection in the central Pacific. The associated Rossby wave vorticity source (S) anomalies keep the Pacific jet west of 150 degree W. A westward shift of the storm track to the North Pacific also contributes to dry conditions in the SW and wetness in the PNW. When enhanced tropical convection is located near 150 degree E, substantial contributions to outgoing longwave radiation anomalies are from fluctuations in the intraseasonal band. A wave train extends from the convective area in the Tropics to North America, where negative 200-hPa streamfunction anomalies are consistent with wetness in California and dry conditions in the PNW. When tropical convection is enhanced in the central Pacific from the date line to 135 degree W, most contributions are from the interannual band. The positive S anomalies associated with an enhanced local Hadley cell extending from the North Pacific to California are responsible in part for the eastward shift of the subtropical jet. The storm track moves southeast and is consistent with wet conditions in the SW.

We used a coupled remote sensing/distributed energy balance snowmelt model (SNODIS), and used previously validated results from a high spatial (30 m) and temporal (hourly) resolution model run in ELW as a control. We selected spatial resolutions that are commensurate with standard product DEMs (digital elevation models) or with existing or planned satellite remote sensing data, and temporal resolutions that are factors of typical operational intervals for meteorological data. We degraded the spatial resolution of the DEM from 30 m to 90, 250 and 500 m prior to computing the distributed micrometeorological data. We degraded the classified remote sensing data to the same spatial resolutions prior to computing the duration of the snow cover. Similarly, we degraded the temporal resolution of the micrometeorological data from 1 h to 3 and 6 h prior to computing the distributed energy balance and snowmelt. We compared mean basin SWE, basin snowpack water volume and the spatial patterns of SWE from each test with our previous, high resolution results. We found no significant differences between the mean basin-wide SWE computed from the 250 m and 500 m spatial resolutions and that of our high resolution control, regardless of temporal resolution. At each temporal resolution mean basin SWE was overestimated at the 90 m resolution by 14-17%. Coarsening of the spatial resolution did result in a loss of explicit information regarding the location of SWE in the basin, as expected. We discuss these results in terms of their implications for applying the SNODIS model to larger regions.

An additional 19 otoliths came from fishery-independent samples from the South Atlantic Bight for fish smaller than 254 mm total length (TL), which is the legal size limit. Marginal increment analysis revealed that rings on the otoliths were deposited annually. This observation is further substantiated by the increasing modal radius of each age ring corresponding to the increasing modal size of the fish at age. Observed ages ranged from age 1 (202 mm mean TL) to age 14 (535 mm TL). The largest fish was 600 mm TL and was estimated to be age 13. The weight-length relationship was described by the equation: W = 9.55 x 10 super(-9)(L) super(3.04), where W = whole weight in kilograms and L = total length in millimeters. The von Bertalanffy equation was estimated using the inverse, weighted, back-calculated lengths at the last annulus. The equation was L sub(t) = 650 (l - e- super(-0.144(t+0.238))), where t is age in years.

During the 1970s, landings averaged about 5,000 mt. The International Commission for the Conservation of Atlantic Tunas (ICCAT) established a total allowable catch (TAC) of 1,160 mt in 1982 and has set limits ranging from 1,995 to 2,660 mt annually since. The Commission's assessments indicate that unrestricted fishing through the 1960s and 1970s resulted in a sharp decline in abundance, primarily because heavy fishing on young fish wasted potentially good recruitment.

AN - 17127076; 4430655 AB - Shredded scrap tires were leached in a modified toxicity characteristic leaching procedure (TCLP) extraction method in synthetic saltwater solutions for three sequential 7-d periods. Test salinities were 5, 15, and 25ppt. Acute toxicity tests were conducted with larval sheepshead minnows Cyprinodon variegatus and daggerblade grass shrimp Palaemonetes pugio. Mortality decreased following multiple sequential leaching periods. Toxicity decreased with increasing salinity. The fish were more sensitive than the grass shrimp. Dilution series toxicity bioassays were performed with fish and grass shrimp at 5ppt salinity and at 15ppt with fish only. The 96-h LC50s (lethal concentration for half of the test animals) for fish were 10% leachate at 5ppt and 26% at 15ppt. The 96-h LC50 for grass shrimp at 5ppt was 63%. The 96-h lowest observed effect concentrations (LOEC) for fish survival were 12.5% at 5ppt and 25% at 15ppt. The 96-h LOEC for grass shrimp survival was 50% at 5ppt. Growth LOEC values were 12.5% at both salinities for fish and 50% for grass shrimp at 5ppt. Chemical analyses revealed no specific components as the cause of observed toxicity. Antagonism between sea salt and toxic chemicals is hypothesized to cause differential toxicity at varying salinities, as opposed to differential solubility of the toxicants. Extrapolation of laboratory results indicates that proposed tire reefs should not pose a serious threat to water quality in Chesapeake Bay. No observed effects concentrations (NOEC) were an order of magnitude or greater above field concentrations calculated from simplified methods. Toxic substances appear to leach from the surface of the tires not from the tire matrix. The use of tires in higher salinity environments appears to pose little direct toxicological risk to resident organisms. However, because unknown toxic chemicals were present in leachates at all test salinities, no assessment can be made regarding persistence, fate, transport, or possible bioaccumulative effects.

We investigate sea ice kinematics from October 1993 through April 1994 using relative motions from 13 drifting buoys with Global Positioning System navigation in a 20-km array centered on the Sea Ice Mechanics Initiative ice camp, and we compare these motions to synthetic aperture radar (SAR)-derived ice velocities over a 100- by 500-km region in the Beaufort Sea. There is excellent correspondence between the deformation of the buoy array and that from the SAR. Inferred ice dynamics from analysis of the two major northerly wind convergence events of the winter are consistent with a granular hardening plastic conceptual model for Beaufort sea ice. Under continued northerly winds the ice from the Alaskan shore to the camp failed in shear and convergence, in a progressive manner away from the coast. The continuum scale O(10 km) is an order of magnitude larger than the grain, i.e., floe, size O(1 km). The ice motion often forms aggregates of 20-200 km separated by narrow (<10 km) shear zones, similar to granular materials. At moderate forcing, i.e., wind stress multiplied by fetch, the ice appears to fail along slip lines that occur at an acute angle to each other and to the direction of the wind forcing, characteristic of a plastic material at critical state. With longer fetch the ice appears to fail in compression, perpendicular to the wind direction. Sea ice appeared to harden on a regional scale after the first event. During the second northerly wind event there was a sea ice breakout toward the west, apparently due to a lack of lateral confining stress. Our observations suggest that the ice floes advect through relatively stationary stress fields, created by the wind forcing and coastal boundaries. For example, while the SAR and advanced very high resolution radiometer images indicated the presence of the shear feature at the same geographic location for nearly a week, buoys would show shearing only for several days as they transited across the region of shear. There is a high correspondence between the major internal ice deformation events and persistent weather patterns on a 3- to 5-day temporal scale. This implies that SAR data collection and analysis for regional sea ice dynamics should be consistent with the wind forcing and have a sampling of less than 3 days.

Densities and lengths of larvae were significantly different among sampling dates, with distance offshore, and between sides of the inlet. Flood-tide stage had minimal effect on larval densities and lengths except for P. albigutta and P. lethostigma. Changes in larval densities with distance offshore were not coherent among species; densities of B. tyrannus increased offshore whereas densities of the other species decreased offshore. Average larval densities on a sampling date were coherent among species. Patterns in larval lengths were also coherent among the four non-flounder species. Larval densities outside of Beaufort Inlet were correlated with larval densities inside of Beaufort Inlet. Larval densities outside of Beaufort Inlet were also correlated with the north component of the wind, nearshore water temperature, and distance to the mid-shelf front. Differences in larval density across the inlet were significantly correlated with the east component of the wind. The patterns in larval densities outside of Beaufort Inlet were complex and apparently influenced by both the physical processes that supply larvae to the nearshore region and nearshore physical dynamics.

Their survival, growth, reproduction, and abundance are influenced by both natural processes and events and by human activities. How such activities might affect the survival and abundance of blue crabs is the focus of this discussion. Because the life cycles and growth of blue crabs and other crustaceans are relatively complex, they are vulnerable to chemical and physical alterations to their habitat in different ways during their life. Not only are insults to the different life stages important, but negative impacts to the food webs that support them may also be damaging. When dealing with human-induced alterations to the environment, we often become preoccupied with the introduction of toxic chemicals and pesticides and their effects on individual organisms, and overlook less emotionally charged but more widespread threats, such as nutrient loading, alterations of freshwater inflow, and physical destruction of estuarine and coastal habitat. Increasing human population densities and development near the Atlantic and Gulf of Mexico coasts may pose the greatest threat to blue crab populations through alterations of upland watersheds with increased runoff, erosion, and turbidity, and increased nonpoint-source runoff of chemicals and nutrients. Unless these activities are adequately controlled, the degradation of coastal habitat necessary for the survival and growth of blue crab populations will grow.

Model equations to remove this limitation are developed. These simulate time-dependent flow in a long, ventilated, vertical shaft with an arbitrary vertical density distribution, including one or more intervals along the shaft length where the vertical distribution of the averaged cross-section density may be unstably stratified, i.e., density increasing with increasing elevation. The model equations are partially verified by favorable comparisons between solutions and previously published data from unsteady experiments in long vertical tubes involving initially unstable configurations: saltwater over freshwater and heavy gas over light gas.

We have studied the structure of this region in greater detail by directly observed super(15)N NMR of oxidized and reduced putidaredoxin preparations in which the six cysteine residues are selectively labeled with super(15)N. A new method for preparation of a stable form of reduced putidaredoxin has been developed for use in NMR. The super(15)N NMR spectra of the oxidized and reduced forms are characteristically different, and we have measured and compared super(15)N chemical shifts, spin-lattice relaxation times (T sub(1)), and chemical shift/temperature dependences for both forms. Evidence for localized valencies of the iron atoms in the reduced form is presented. From the super(15)N T sub(1) values of the oxidized form, reduced distances of the cysteine backbone super(15)N nuclei from the center of the Fe sub(2)S sub(2) cluster have been calculated. These distances are consistent with those calculated from X-ray crystal structure data for five ferredoxins, and confirm the structural similarity of the Fe sub(2)S sub(2) clusters in putidaredoxin and in these ferredoxins in the oxidized state.

AN - 36404944; 7052 AB - PURPOSE: The development of a business park, partially funded under Title I of the Economic Development Administration's (EDA's) Public Works and Development Facilities Program, located in northeastern Pennsylvania, is proposed. The 1,124-acre Mosaic Mountain site, which was selected from 20 candidate sites, is located eight miles northeast of the city of Scranton, northeast of the intersection of Marshwood Road and SR 247, within the Mosaic Mountain range, straddling Jessup and Olyhant boroughs. The economy of the area has historically relied on coal mining, iron and steel production, and textiles, but since 1945 these industries have been in steady decline. Four alternatives, including a No Action Alternative, were considered in the draft EIS. This supplemental draft EIS provides additional information in response to public comments recommending that further attention be given to the potential impacts to biological resources resulting from the proposed project at the preferred site, the analysis of alternatives, particularly sites originally screened and eliminated from further consideration, and the potential cumulative and secondary impacts associated with the proposed project as well as other related issues. Amongst the major issues addressed in this supplemental EIS are a wastewater collection system proposed by the Small Business Administration and a proposal by the Federal Bureau of Prisons to construct a prison in the area; the latter proposal has been withdrawn. The business park would provide development sites of various sizes to firms interested in modern manufacturing, distribution, and office facilities. The local applicants (Scranton Lackawanna Industrial Building Company and the Borough of Jessup) would market the park to prospective tenants in an attempt to recruit high-value jobs to the area. Under the proposed plan, individual industrial facilities would range on size from 50 to 100 acres. The applicants have requested $2.0 million from EDA in order to provide water supply and roadway improvements, while funds from other sources would be used to construct other needed infrastructure improvements. POSITIVE IMPACTS: The park would stimulate growth in an economically distressed area, generating up to $200 million in private investment and supporting up to 5,000 new jobs. NEGATIVE IMPACTS: The development would result in the disturbance of vegetation, wetlands degradation from increased surface water runoff, sedimentation, and road salt runoff.

AN - 36404655; 7048 AB - PURPOSE: The amending of the anchovy fishery management plan (FMP) for the western Pacific pelagic fisheries to extend the plan to cover other coastal pelagic species (CPS) is proposed. The FMP applies to fisheries operating in the U.S. Exclusive Economic Zone (EEZ) in the Pacific. The management plan covers commercial harvest and use as well as recreational harvest and use. Warming ocean temperatures have led to an increase in the abundance of Pacific sardines, which are now found off Mexico, California, Oregon, Washington, and Canada, placing management of this species beyond the authority of any individual state. The collapse of the historical sardine fishery in the 1950's was due to overcapitalization and resulting overfishing at a time of unfavorable environmental conditions. If action were not taken, it is likely that the CPS fishery would become overcapitalized faster than management authorities can react should sardine, or other CPS, increase in abundance or markets develop. This 8th Amendment to the plan, which was first established in 1978 and last amended in 1994, would add the following CPS to the management regime: Pacific sardine, Pacific (chub) mackerel, jack mackerel, and market squid to the fishery management unit; the regime currently covers only northern anchovy. The amendment would also change the name of the plan from the "Northern Anchovy Fishery Management Plan to the "Coastal Pelagic Species Fishery Management Plan." In addition, the amendment proposed system of "actively managed" and "monitored only" species to allow the direction of management and research efforts where they are most needed. The plan would also include a limited entry program for pelagic finfish species south of the 39 degree north latitude. The management plan would include harvest policy options that preserve a portion of the stocks as forage for marine mammals and birds while maintaining a stable fishery and an Essential Fish Habitat section, both of which conform to the requirements of the relevant legislative mandate, as well as bycatch and incidental catch allocations. Alternative addressed in this draft EIS include those related to management entry, management strategies, optimum yield and maximum sustainable yield, overfishing definitions, and essential fish habitat. The amended plan would constitute a framework management process allowing fishery authorities to change and modify management procedures in an ongoing fashion. POSITIVE IMPACTS: The amendment would provide comprehensive management of CPS in the fishery in response to rapid development in the harvesting of the affected species. The overcapitalization of the species added to the management plan would be prevented. NEGATIVE IMPACTS: Framework management decisions could have adverse localized economic impacts on commercial fishing interests.

AN - 36414827; 7063 AB - PURPOSE: The dredging and disposal of dredged material in relation to the maintenance of the federal navigation project in the Providence River and Providence Harbor, located in Rhode Island, are proposed. The federal project, a 16.8-mile channel, begins near the head of Providence Harbor and follows the river on a southerly course to deep water near Prudence Island. The upper 2.5 miles comprise the main harbor. The Providence River and Providence Harbor together constitute the principal commercial waterway in Rhode Island. The deep-draft traffic in the Providence River and Providence Harbor consists mainly of tankers, barges, and general cargo vessels. There has been no significant dredging in Rhode Island since 1976. Since that time, shoaling has reduced controlling depths in the channel to as shallow as 30 feet below mean low water. The present level of shoaling has forced the Coast Guard to place one-way traffic and draft restrictions on ship traffic in the channel. A total of 158 potential disposal sites were screened, along with the impacts of 17 projects submitted by applicants for federal permits. Some 29 disposal options at 18 locations for dredged material disposal are considered in this draft EIS. Disposal alternatives include upland, open water, and confined aquatic disposal, as well as beneficial uses of the dredged material. The preferred alternative would involve dredging the federal channel and harbor to the authorized depth of 40 feet below mean low water, disposal of approximately 1.2 million cubic yards (mcy) of contaminated dredged sediment in a confined aquatic disposal cell near the channel, and disposal of approximately 4.4 mcy of clean material in Narragansett Bay at a site located between Prudence and Hog islands. The estimated cost of the preferred alternative is $88.8 million. POSITIVE IMPACTS: The navigational efficiency of the harbor would be restored and maintained, supporting the local and regional economy. Deep draft navigation would provide for cost reductions for shippers transporting goods, reductions directly related to the costs consumers pay for products such as gasoline, home heating oil, and other products. The disturbance of bottom sediment by ships passing over shoals would cease, and the possibility of groundings and oil spills would decline significantly. NEGATIVE IMPACTS: The dredging and disposal operations would result in temporary increases in suspended solids and contaminants in the water column, burial of aquatic resources, and the resultant economic impacts on the fishing interests dependent on the bay.

These high values, measured during gas extraction by crushing in vacuum, are similar to the highest magmatic (super 3) He/ (super 4) He ratios found in young terrestrial volcanic rocks. By analogy with young basalts, in which crushing selectively extracts magmatic helium, any significant cosmogenic (super 3) He appears to be absent in these picrites. Additional evidence for the absence of cosmogenic helium is provided by fusion results on the crushed olivine powders and by a single stepwise crushing experiment, in which only magmatic and radiogenic helium components are resolvable. The West Greenland picrites have Pb, Nd and Sr isotope compositions which overlap those found in picrites from Iceland and in basalts from Loihi Seamount, localities which today also have high (super 3) He/ (super 4) He ratios. Isotopic variations in He, Pb, Nd and Sr for the West Greenland picrites are interpreted to largely result from interaction of the early Iceland mantle plume with the upper mantle during plume ascent and dispersion beneath the continental lithosphere. The presence of high (super 3) He/ (super 4) He ratios in West Greenland, and the onset of magmatism across the North Atlantic Volcanic Province near 62 Ma, supports the hypothesis for very rapid dispersion (>1 m/year) of mantle plume head material during the earliest stages of plume impact, as predicted in recent numerical simulations of plume behavior during thermal mantle convection with non-Newtonian rheology.

Stable element analyses were combined with radiometric measurements to determine the most probable geochemical host phases of these actinides in reference sediment IAEA-135. (super 241) Am results indicate an association with carbonate minerals and organic matter. The extraction profile of (super 238) U was similar to that of refractory elements Al, Ti, and K. (super 239/240) Pu data suggest a fractionation of Pu into Fe-bearing phases of varying solubility. The reproducibility of the method was quite good (replicates agreed to within 10% at a 95% confidence level).

The average time for the dissemination of these warnings has been about 55 minutes. In most cases tsunami destruction has been confined to localities that are within one hour's tsunami travel time from the source. While the Warning Center's warnings may not reach those most affected by recent tsunamis, the information is nevertheless of great value to those emergency managers further down stream of the spreading tsunami. An examination of the warning process indicates the need for more feedback from the participants receiving the warnings regarding the applicability of the information to their needs and, if they are affected by the tsunami, a timely summary of these affects that can be used to ascertain the severity of the tsunami. The study also points up the critical need for independently functioning regional tsunami warning centers.

The program was called SEMS, for the Seafloor Earthquake Measurement System. The purpose of the program was to characterize the nature of the response of earthquake ground motions for use in the design and reassessment of offshore platforms used in petroleum drilling and production. The United States Geological Survey (USGS) was given a contract to provide seismological analysis of data obtained from the SEMS program and compared it to data from earthquakes measured onshore. This paper provides an overview of the work by the USGS on this initivative.

The performance based design is an emerging art, which was born from the lessons learned from the recent earthquakes in 1990's. This is to overcome the limitation in the conventional seismic design, which was based on the force balance against a design seismic force. The performance based design is a user friendly approach to take into account the requirements of the seismic performance of a structure against the probabilistic occurrence of earthquake motions. This paper is an initial proposal of the seismic performance based design for port structures.

They provide critical quantitative measurements of damaging earthquakes in urban environments needed for mitigation of future earthquake losses. The present critical lack of strong-motion information emphasizes that urgent action is required to significantly increase resources to adequately record future damaging earthquakes. Recent estimates for the US suggest that an urgent need to record the next major earthquake adequately throughout stricken urban areas requires that instrumentation and recording efforts be increased by nearly 20 times within the next five to ten years (Stepp, 1997; Borcherdt, et al., 1997). Justification for this dramatic increase as prepared by the "Committee for the Future of the US National Strong-Motion Program" (Borcherdt, ed., 1997) is summarized here.

Recent years, a strong demand for the preservation of natural environments has been accompanied by the need for bridge construction methods that have minimal effects on nature. To meet this new requirement, high bridge piers must be constructed. In response to these circumstances, rationalize execution and to develop the 3H (Hybrid Hollow High Pier) Method: a new high bridge pier structure that is both economical and provides earthquake resistance.

Consequently, if cyclic strengths, either from laboratory measurements performed at a confining stress of 1 atm or estimated from correlations to in situ measurements such as Standard Penetration Tests (SPT), are linearly extrapolated to higher effective confining stress levels, the calculated liquefaction resistances may be too high. The effect of confining stress on liquefaction resistance is further complicated by soil compressibility and stress history. The state-of-the-practice approach to account for the non-linear relationship between liquefaction resistance and vertical effective stress is to use published charts derived from existing laboratory data on similar materials or to determine a site specific relationship with a comprehensive laboratory testing program. Whichever approach is used, liquefaction resistance is conventionally represented as the Cyclic Resistance Ratio (CRR, the ratio of cyclic shear strength divided by the vertical effective stress, sigma (sub v) '). For a given soil at a given consistency and stress history, the CRR generally decreases with increasing vertical effective stress. This decrease is described by the factor K (sub sigma ) which is defined as the ratio of CRR for a given sigma (sub v) ' to the CRR at a vertical effective stress of 1 atm, CRR (sub 1) (compared at the same relative density).

The postulated maximum credible earthquake (MCE) for Hoover Dam is a magnitude Ms 6.75 on the Mead Slope Fault. Initial structural finite element analysis calculated stresses larger than the tensile strength on the upper portions of the dam. More sophisticated analysis followed when additional data was obtained for material properties and seismic loading. The first approach was a linear-elastic analysis incorporating foundation-structure interaction with mass in the foundation. The second approach was a non-linear analysis incorporating concrete cracking and contraction joint interaction using smeared crack techniques and kinematic stability analysis of the top of the dam.

The observation system includes 11 observation sites and a control center. A number of records with intermediate amplitudes have been obtained to this date. In this report, the earthquake observation system is introduced at first. The description includes the outline of the geological condition of the Sendai area, the objective area of the observation, the surface geology of the 11 observation sites from the investigation in sites, and the recorded data until the project started. During the period, the seismic activity of the area was not so high. Therefore, the amplitudes of acceleration records are not large enough to be called "strong motion". However, these data are essential for the purpose to examine the dynamic amplification property of the surface soils.

The building code in Japan will be changed from current prescriptive type into performance-based type in a few years. In responding this announcement, the performance-based building code is now under development at the Building Research Institute (BRI). In this paper, presented is the framework and concepts of the performance-based seismic and structural provisions in Japan proposed by BRI. In the principles of structural safety, the required performance and loads/forces levels are clearly defined. There are four routes in verification procedures and associated structural specifications following the principles of structural safety; proposed route, conventional route, small building route requiring no calculation, and other route including alternative verification procedures, deemed-to-satisfy provisions, and expert judgments. Seismic effects to buildings are considered on the basis of basic seismic design spectrum defined at the engineering bedrock under surface soil layers. There are three levels in the objectives and requirements to building structures and loads/forces levels. The objectives are life safety, damage prevention, and continuous normal operation of a building. The principle of verification procedures is that the predicted response values should not exceed the estimated limit values. The newly proposed verification procedure for major earthquakes is illustrated, as all others remain basically the same as those actually in use. There are indeed various analytical methods for predicting the response of structures subjected to earthquake excitations. The one which is shown here is based on the equivalent single-degree-of-freedom system and response spectrum method.

It has emphasized the importance of earthquake engineering research into why and how structures collapse in real earthquake conditions and these processes are reproduced numerically. Considering the lessons learnt from recent earthquake disasters, NIED plan to construct a "3-D Full Scale Earthquake Testing Facility," which will be able to simulate the process of destruction of structures. This facility will be a central tool in a new concept of research bases for earthquake disaster prevention. NIED was conducted the research and development of core technology, such as the big and high performance hydraulic actuators, which have a long displacement and high velocity, and high performance three dimensional link joint since 1995 by the 4 year project. We constructed the prototype shaking table systems and confirmed the performance tests. NIED will begin the design and construction of this new facility in fiscal year 1998. This paper summarizes the fundamental concept of the facility and the result of R&D of core technology.

The factors controlling the amplitude of such motion, however, are not widely understood. Compared to the body wave, the velocity of the surface wave is much less, and, as a result, the curvature of the wavefront and the geometric spreading are much less. The surface wave behaves approximately as if it were generated by a line source in a two-dimensional medium. On the other hand the low-Q basin sediments produce significant anelastic attenuation, even at relatively long periods. A study of pseudovelocity response spectra of records of the 1971 San Fernando and 1994 Northridge earthquakes at sites in the Los Angeles Basin shows that late-arriving surface waves with group velocities of about 1 km/sec dominate the ground motion for periods of 3 sec and longer. The rate of amplitude decay for these waves is less than for the body waves and depends significantly on period, with smaller decay for longer periods. The amplitude can be modeled by anelastic attenuation with decay proportional to the exponential of distance multiplied by an attenuation coefficient. Methods for estimating the response spectral amplitudes for these waves in future earthquakes are presented based on either the San Fernando or Northridge data. The response spectral amplitude of surface waves from the Northridge earthquake is less than from the San Fernando earthquake by factors as large as four. The surprisingly large difference between the San Fernando and Northridge earthquakes can be explained, at least in part, by directivity. Estimates of response values in future earthquakes based on the two different data sets give a sense of the range of possibilities. These estimates are based on data from the Los Angeles Basin, but, in the absence of other data, they could be applied to sites in other deep Quaternary basins. The results presented in this paper indicate that inclusion of anelastic attenuation may be essential in modeling ground motion in deep sedimentary basins. Future progress in understanding strong motion from basin surface waves calls for attention to faithful recording of the long-period components of ground motion and to recording motion for times long enough to include the late-arriving surface waves.

The overall objective of the total program is to improve seismic safety practices in both countries through cooperative studies to determine the relationship among full-scale tests, small-scale tests, component tests, and related analytical and design implication studies. A five-year research program on Composite and Hybrid Structures was recommended to start in 1993 fiscal as the Phase 5 based on a number of technical meetings between the U.S. and Japan. Because of diverse and broad scope of the subject area, the research program was organized into the following four groups: Concrete Filled Tube Column Systems; Reinforced Concrete (RC) and Steel Reinforced Concrete (SRC) Column Systems; RC/SRC Wall Systems; and New Materials, Elements and Systems. In addition to the objectives of the total program, Phase 5 aimed at (1) developing design guidelines (for a unified code development) for typical composite and hybrid structures, and (2) developing new and innovative composite structural elements and hybrid systems using advanced new materials and/or devices. Japan side has just completed his assignment of the cooperative research work in the fiscal year of 1997. This report presents the outlines of the research conducted during five years and the general contents of the proposed draft guidelines.

This system is expected to provide quick and appropriate decision making in all three phases, "preparation", "emergency measures" and "recovery/rehabilitation". Since April 1996, the National Land Agency has been operating the Early Estimation System (EES) which automatically estimates the scale of damage caused by an earthquake using the very limited information available immediately after an earthquake occurs. Currently, the agency is pursuing the development of an Emergency Measures Support System (EMS), which will consolidate and share information through the construction of an on-line network linked with other disaster-prevention organizations, and utilize such information in support of emergency measures such as rescue and medical care, emergency transportation, evacuation, lifelines, and volunteers.

This project has been made through the joint research program between Public Works Research Institute, Public Works Research Center and 17 private companies. Developed seismic isolation systems for the underground structures are made by constructing the isolation materials with low-shear modulus around the underground structures to absorb the effect of ground deformation. Five kinds of seismic isolation materials have been developed and the analysis and design methods for the underground structures with the seismic isolation systems have been also studied and developed. The final accomplishment is compiled as a "Draft Manual for Seismic Isolation Design of Underground Structures" in March 1998.

Performance goals are defined in terms of a minimum annual seismic failure frequency. Pushover analyses are used to determine the building's ultimate capacity and relate the capacity to roof drift and joint rotation. Nonlinear dynamic analyses are used to quantify the building's drift versus earthquake magnitude using a suite of time histories representing varying soil conditions and levels of seismic hazard. A probabilistic correlation between joint rotation and damage state is developed from experimental data. The results of the deterministic pushover and nonlinear time history analyses are evaluated statistically to develop a probability of seismic failure or fragility. The building fragility level is convolved with the seismic hazard curve to determine annual seismic failure frequency.

Accelerometers are the most common instruments used to monitor structural systems during earthquakes or strong winds, but to arrive at displacements requires processing including double integration. In most cases, such processing does not take place in real-time or near real-time because of requisite steps including choice of filters for signal processing. These choices could introduce errors at periods relevant to structural response. However, recent advances in Global Positioning System (GPS) technology recording at 10 samples per second (sps) allows reliable monitoring of long-period structures such as suspension or cable-stayed bridges and tall buildings. GPS units with a capability of resolving motion at the centimeter level (+ or -1 cm for horizontal, + or -2 cm for vertical accuracy) with sampling rates of 10 sps are now available from several manufacturers. The majority of tall buildings (20-40 stories or more) are flexible steel framed structures whose fundamental period (T, in seconds) can be estimated with the empirical formula T = 0.1 N, where N is the number of stories of a building. Thus, the frequencies corresponding to the fundamental periods of most buildings over 20 stories are 10-20 times the Nyquist frequency of the sampling, which is sufficient to assess accurately its average drift ratio. With this method, displacement is measured directly in real-time. In this paper, we discuss the scientific justification and feasibility of using GPS technology to monitor long-period structures. We describe an experiment simulating the response of a tall building. The results indicate that sampling at 10 sps provides a clear and accurate response history from which drift ratios and dynamic characteristics of the specimen can be derived. The paper discusses in detail how data recorded from tall buildings monitored with GPS units can be used by engineers and building owners or managers to assess the building performance during extreme motions caused by earthquakes and strong winds, by establishing threshold displacements or drift ratios and identifying changing dynamic characteristics. Such information can then be used to secure public safety and/or take steps to improve the performance of the building.

Two points are included in the paper: i.g., a new system architecture to realize SIS with systematic control, possibility of extension and the independence of the subsystems, and several element technologies applicable to the subsystems of SIS. The proposed concept does not only concentrate on the technologies of the supply-side, but also the philosophy and the technologies that is "objective oriented." As the counter-earthquake activity system is responsible many complex jobs at a time, and as the information technologies is becoming highly technical, the concept introduced here is very much help for the personnel of the counter-earthquake activity system.

In case of houses, it is difficult to elongate a period of building by laminated rubber bearing isolators because of the light weight of building. In addition to rubber bearing devices, sliding and rolling type devices are needed to be developed or applied. In this paper, the effects of base isolation on response of houses and mechanical characteristics of various kinds of seismic isolators will be discussed. Shaking table tests of base isolated house models were carried out. Various kinds of isolators, such as rubber, sliding, and rolling bearings were tested. The effect of these isolators on the response of a superstructure during earthquakes has been demonstrated, through the comparison with response for a non-isolated house. It is shown that the response of houses is remarkably dependent on characteristics of isolators.

For the purpose of the geotechnical earthquake studies, a powerful electro-hydraulic shaking table designed to work in the centrifuge has also been developed. This shaking table provides 40G shaking acceleration to a model of 1 ton, which acceleration is equivalent to the maximum ground acceleration observed during the 1995 Hyogoken Nanbu earthquake for a model at 50G centrifugal acceleration field. The centrifuge has been under extensive use to investigate various geotechnical problem. Results of centrifuge tests carried out so far are briefly described.

The research work in Japan started in fiscal year 1993. However, fuller participation of researchers on both sides started in early summer 1995. The sponsorship of the program is by the National Science Foundation in the U.S. and by the Ministry of Construction along with a number of industry groups in Japan. This paper presents a brief status report of the program and research progress made to date on the U.S. side. Because of diverse and broad scope of the subject area, the research program is organized into the following four groups: Concrete Filled Tube Column Systems (CFT); Reinforced Concrete (RC) and Steel Reinforced Concrete (SRC) Column Systems (RCS); and RC/SRC Wall Systems (HWS); New Materials, Elements and Systems (RFI). A theme structure with well selected layout, geometry and design loads for the research is also presented, which provides a common focus for various systems to be studied, and also a common prototype structure from which the components and sub-assemblages are drawn.

However, there was no damage on dams which affected the their safety. This paper introduces the characteristics of ground acceleration observed at dam sites during the Kobe Earthquake and discusses the effect of vertical seismic motion and the safety of concrete gravity dams in such big earthquakes. The result of the dynamic analysis shows that concrete gravity dams have the high safety against such big earthquakes.

The investigations about the mortality and morbidity due to both direct and indirect health effects at the community level are required to identify the most effective countermeasures in the pre-impact and post impact phase. As an example of indirect health effects, age-adjusted death rates of acute myocardial infarction were compared among several affected regions. In Nada, Higashi-Nada, Hyogo, Nagata districts in Kobe City we observed the sharp increase in the average death rates between January and March, 1995 in comparison with 1994 and 1996. Outside of Kobe City, the similar increase was observed in Amagasaki and Tsuna. The different patterns in the increase of rates between January and March, 1995 are suggestive of the multiple risk factors. The further investigation is required to identify the environmental factors (structural and non-structural) to reduce the total health outcomes.

As a wrap-up to the program, research results are being reviewed and assessed in order to determine the impact that their results may have on the future development of a consistent seismic design specification for highway structures. This paper summarizes some of the important results of the research conducted under the program and discusses issues resulting from this impact assessment task with respect to expected effects on future design practice.

The maximum recovery of silicic acid is achieved by thawing the frozen samples in a refrigerator (at 4 degree C) in the dark for at least four days. This method significantly improves the recovery of silicic acid from frozen fresh water samples. It also permits close to 100% recovery of reactive silicic acid from frozen seawater samples even after three months storage.

Data on abundance and distribution are typically scarce for rare species and are mostly in the form of incidental observations, such as fisheries bycatch or museum collections. An objective and quantitative method of evaluating the status of a rare fish species in selected systems - one that is based on incidental observations and that could be used to provide a first warning to managers that a species may be extirpated - would be highly desirable. In this paper, we review two methods that use incidental observations for estimating the probability that a species is extirpated, and we demonstrate the methods with available data sets for Atlantic sturgeon Acipenser oxyrinchus and Alabama sturgeon Scaphirhynchus suttkusi. Special considerations should be made when applying the methods to data sets for fish species. We recommend against using or combining data sets that contain both early life stage and adult observations, and we recommend that priority should be given to data sets obtained in preferred habitat areas. Ancillary information that could provide additional insight regarding the status of the species in the system should be used whenever possible. Finally, we offer a protocol for assembling information and estimating the probability that a fish species is likely to have been extirpated from a system.

A group of juvenile chinook salmon was graded by size into small and large categories; half the fish in each category were reared at an elevated temperature beginning in mid-February, resulting in four distinct treatment groups: large-warm, large-cool, small-warm, and small-cool. Fish from warmwater treatment groups displayed significantly higher growth rates through the spring than coolwater groups. Fish were released into a natural creek on two dates (25 March, release 1 and 12 April, release 2), and downstream movement was monitored. For each release, fish that migrated past a weir within the first 5 d postrelease had significantly higher spring growth rates than fish that did not migrate within that period. A similar comparison of release length to migration demonstrated significant differences only in release 2. Also for release 2, fish from the large-warm and small-warm treatment groups were recovered in higher proportions than fish from large-cool and small-cool groups. These results indicate that fish with relatively higher spring growth rates moved downstream sooner than fish with relatively lower growth rates. Furthermore, smolt size and migration were related with larger fish moving downstream sooner than smaller fish; however, this relation was weaker than that found between growth rate and migration.

Our evaluations were performed systematically over large (1/4 ha) sites in order to make generalizations as to the effect of bioturbation at the scale at which seagrass landscape patterns are discerned. Eighteen 50 x 50 m sites, representing a wide range of seagrass bottom cover, were surveyed seasonally for 2 yr at 1 m resolution to describe the spatial heterogeneity of seagrass cover on the sites. We measured a number of environmental factors, including exposure to waves, tidal current speed, percent seagrass cover, sediment organic content and silt-clay content, seagrass shoot density, above- and belowground seagrass biomass, and numbers of bioturbation pits in the bottom. Seagrass bed cover ranged from 13 to 100% of the site, with 0 to 1.3% of the seafloor within the site showing discernable bioturbation pits. Three sites were selected for detailed study where we marked both existing bioturbation pits and new ones as they formed over time. Pits were measured every 1 to 3 d for width, length and depth until the pit was obscured; pit duration averaged similar to 5 d with an observed maximum of 31 d.

Its maximum lipid concentration of 67% of dry mass - consisting largely of wax esters - is the highest reported for freshwater zooplankton and is among the highest reported for marine polar species. The high lipid concentration of L. macrurus runs counter to the paradigm that high wax ester concentrations are found in herbivorous, but not in carnivorous, polar species. Lipids are drawn down to extremely low levels (10% of dry mass) during the reproductive period, November-May. Reproduction in this univoltine species appears to be timed so that the new generation develops during the high abundance of prey (crustacean microzooplankton and net phytoplankton) in spring. A high wax ester content may allow egg production to start in winter when the prey concentration is low. In contrast to many polar species, the new generation moves through all copepodid stages to adult without diapausing. Copepodid 5 females have a low lipid concentration, and lipids are slowly built up in new generation adults during summer and fall before reproduction commences. This lipid and life cycle strategy may have given L. macrurus an advantage over potential freshwater competitors, such as the arctic freshwater cyclopoid copepod Cyclops scutifer, in the hypolimnia of glaciated lakes.

ER - TY - JOUR T1 - Distributions and recent changes of carbon monoxide in the lower troposphere AN - 17103059; 4416974 AB - Since 1988, the distribution of carbon monoxide (CO) in the lower troposphere has been determined using a globally distributed air sampling network. Site locations range from 82 degree N to 90 degree S, with wide longitudinal coverage, and represent the marine boundary layer, regionally polluted atmospheres, and the free troposphere. In this paper, times series from 49 sites are discussed. With an average lifetime of similar to 2 months, CO showed significant concentration gradients. In the marine boundary layer, mixing ratios were greatest in the northern winter (200-220 ppb) and lowest in the southern summer (35-45 ppb). The interhemispheric gradient showed strong seasonality with a maximum difference between the high latitudes of the northern and southern hemispheres (160-180 ppb) in February and March and a minimum in July and August (10-20 ppb). Higher CO was found in regions near human development relative to those over more remote areas. The distributions provide additional evidence of the widespread pollution of the lower atmosphere. Remote areas in the high northern hemisphere are polluted by anthropogenic activities in the middle latitudes, and those in the southern hemisphere are heavily influenced by the burning of biomass in the tropics. While tropospheric concentrations of CO exhibit periods of increase and decrease, the globally averaged CO mixing ratio over the period from 1990 through 1995 decreased at a rate of approximately 2 ppb yr super(-1).

In this study, we examine how predation risk and food distribution interact to influence the schooling behavior and swimming speed of foraging juvenile walleye pollock, Theragra chalcogramma. Fish were acclimated to either spatially and temporally clumped, or spatially and temporally dispersed food for 3 weeks. Fish were then monitored while feeding in the absence and presence of predatory sablefish, Anoplopoma fimbria. Fish foraging for clumped food swam rapidly in a loose school when predators were absent, but swam more slowly and adopted more cohesive schooling in the presence of predators, trading-off foraging opportunity for decreased vulnerability to predators. Fish foraging for dispersed food swam about slowly and did not engage in cohesive schooling in either the absence or presence of predators. These fish accepted greater predation risk in order to continue foraging, suggesting that the cost of schooling, in terms of decreased foraging opportunity, was greater when food was dispersed than when it was clumped. This lower responsiveness to predators among fish receiving dispersed food demonstrates that predator avoidance does not always take precedence over other activities, but rather, that a balance is maintained between predator avoidance and feeding, which shifts as food distribution changes.

Our interest is focused primarily on ultimate wind loads, that is, loads that are sufficiently large to cause member failure. For non-hurricane regions (1) we comment on issues raised by the fact that directional data published by the National Weather Service are incomplete, and (2) note that, owing to the relatively small sizes of the data samples, results on directional effects for mean recurrence intervals longer than a few hundred years are inconclusive. For hurricane-prone regions we show that, on average, the common practice of disregarding wind directionality effects is conservative for 50-year wind loads. However, according to our results, the degree of conservatism decreases as the mean recurrence interval increases. While individual estimates of speeds with very long mean recurrence intervals are unreliable, statistics based on estimates obtained from large numbers of records can provide useful indications of average trends and suggest that, for mean recurrence intervals associated with ultimate wind loads, the favorable effect of wind directionality tends to be marginal.

As a contribution to the debate needed to achieve such a consensus, we describe an updated method for estimating wind loads that takes into account the directional dependence of the aerodynamic coefficients and the extreme wind climate, and uses the 'peaks over threshold' approach for the estimation of extremes. For hurricane-prone regions, assuming epistemic uncertainties are negligible, we estimate mean recurrence intervals (MRIs) of wind loads inducing the design strength, obtained from 50 yr loads via multiplication by a factor specified by the ASCE 7-95 Standard. For typical aerodynamic coefficients with strong directional preference, depending upon location and building orientation those estimated MRIs varied between less than 1000 to more than 10000 yr. If epistemic uncertainties were taken into account the estimated MRIs would be shorter. We also found that for loads with very large MRIs the common practice of disregarding direction effects is not necessarily conservative from a structural engineering viewpoint.

Distributions of radioactive isotopes are controlled mainly by the isotopic compositions of precursor molecules and radioactive decay processes. As a result, through their isotopic compositions, atmospheric species are traceable to sources and sinks. Thus, isotopic compositions provide useful information for estimating source strengths and for understanding the importance of removal processes in the cycling of the species. The use of radioactive super(14)C and the stable isotopes ( super(13)C and super(18)O) are reviewed here for understanding production and removal processes of CO in the troposphere. Carbon monoxide is a critical component in atmospheric chemistry because of its large effect on levels of OH, the principal oxidant in the atmosphere. In the troposphere, this is due to relatively high concentrations of CO and a short lifetime (2-4 months). Initially, super(14)CO measurements were instrumental in estimating accurately the tropospheric lifetime. Since seasonal super(14)CO variation is controlled largely by OH, super(14)CO serves as an important surrogate measure of tropospheric OH. Global super(14)CO measurements have also been used to estimate the biogenic component of the global CO budget, specifically contributions from biomass burning, oxidized non-methane hydrocarbon (NMHC) emissions, oceans and plants. Research using super(14)CO measurements is also active in quantifying fossil and non-fossil urban emissions. Kinetic isotopic fractionation during production of super(13)CO and C super(18)O from reduced precursors allows one to distinguish, at least qualitatively, different varieties of CO based on seasonal tropospheric isotopic measurements. Difficulties in interpreting the stable isotopic record arise from large fractionation effects that obscure source isotopic signatures (in particular the oxygen kinetic isotope effect for the CO + OH reaction), and large seasonal/latitudinal variability in source fluxes. While dual-isotopic CO source signatures do not allow a direct mathematical determination of contributions from several sources, plots of delta super(18)O vs delta super(13)C may help estimate relative proportions of dominant sources. In addition to understanding CO sources, the pressure dependence of the carbon kinetic isotope effect (KIE) has helped elucidate pathways for the CO + OH reaction. Since formaldehyde (HCHO) is an important intermediate in hydrocarbon oxidation to CO and CO sub(2), the stable carbon and oxygen isotopes in atmospheric HCHO may help distinguish different hydrocarbon sources to regional CO budgets and elucidate the importance of different oxidative reaction pathways.

AN - 16353185; 7015 AB - PURPOSE: The implementation of a comprehensive management program for the coastal zone associated with Lake Superior, located in northeastern Minnesota, is proposed. Lake Superior stretches approximately 350 miles west to east and 160 miles north to south and has a shoreline extending almost 2,800 miles. The lake drains 49,300 square miles, 89 percent of which is forested. The basin extends into Michigan, Minnesota, Wisconsin, and Ontario. Within the coastal area are 12 cities, 15 state parks, a national monument, portions of a national forest, two Indian reservations, and an international seaport. Numerous unincorporated settlements are scattered through the area, most of them hugging the coast. The approval of the program would allow administrative grants to be awarded to the state and require that federal actions be consistent with the program. Minnesota began the development of a coastal management program for the Lake Superior area in 1993. The coastal area as defined by the program's coastal boundary follows the nearest legal coastal township along the shore, or approximately six miles inland. In the metropolitan area around Duluth, the coastal area includes the cities of Duluth, Hermantown, Proctor, Carlton, Wrenshall, and Cloquet and all or parts of the adjacent townships; this area was determined to have the most significant impact on Lake Superior and its tributaries. The currently considered proposal would result in establishment of a 15- to 17-member Coastal Council through an executive order issued by the governor. Three persons from each of the four coastal counties would be chosen as council members. Three types of program organization are recognized through the national program as follows: direct permitting, where the leased state agency directly implements law(s) which regulate or manage coastal development; networked programming, where the lead state agency coordinates with other state and local agencies which together manage land and water uses and protect coastal resources; and local coastal programming, where the lead state agency works with local units of government to develop state approved local coastal programs. Minnesota has developed a networked program. Management policies would address coastal lands and waters, air and water quality, fish and wildlife, forests, mineral resources, energy, environmental review, development and economic revitalization plans, natural resource protection, recreation and water access, cultural resource protection, coastal nonpoint source pollution control, and federal coordination. Three Federal alternatives to program approval would include delaying or denying approval, if certain requirements of the Coastal Zone Management Act of 1972 had not been met. The state could modify parts of the program or withdraw its application for federal approval if either of the above-mentioned federal alternatives resulted from circulation of this draft EIS. POSITIVE IMPACTS: The approval and implementation of the program would enhance governance of Minnesota's coastal land and water uses according to the coastal policies and standards set out in Minnesota's statutes, authorities, and rules. Minnesota's Lake Superior Coastal Program would promote the beneficial use of coastal resources, prevent their impairment, and manage major activities that substantially affect numerous resources. The program would enhance decision-making processes used in determining the appropriateness of actions in the coastal area. NEGATIVE IMPACTS: NONE.

AN - 36405189; 7007 AB - PURPOSE: The amending the fishery management plan for the bluefish fishery in U.S. waters of the western Atlantic Ocean is proposed. All states along the Atlantic Seaboard would be affected. The goal of the management plan is to conserve the bluefish resource along the Atlantic coast. Major objectives adopted during scoping include increasing understanding of the stock and of the fishery; the provision of the highest availability of bluefish to U.S. fishing interests while maintaining, within limits, traditional uses of bluefish; provisions for cooperation among the coastal states, the various regional marine fishery management councils, and federal agencies involved along the coast to enhance the management of bluefish throughout the species' range; the prevention of recruitment overfishing; and the reduction of waste in both the commercial and recreational fisheries. Numerous alternative measures, falling within various categories, as well as a No Action Alternative, are considered in this draft EIS. The preferred alternative would be designed to rebuild the bluefish stock to minimum biomass threshold, which is specified as one-half the biomass level associated with the maximum sustainable yield over a nine-year rebuilding period. For the initial two years (1999-2000), fishing mortality would remain at the current level. Fishing mortality would be reduced by 10 percent during the ensuing three years and by a further 20 percent during the remainder of the rebuilding period. This schedule would allow for stock rebuilding to the level which would support harvests at or near maximum sustainable yield by the year 2007. Permit requirements would include operator permits for commercial and party and charter boats, vessel permits for party and charter boats, vessel permits for commercial vessels (permits to sell), and dealer permits (permits to purchase). Permitted individuals or vessels would be allowed to sell only to permitted dealers and permitted dealers would be allowed to purchase only from individuals and vessels permitted to sell. Party and charter boat operators, commercially permitted individuals, and dealers would be required to report regarding compliance with permit requirements. The plan would incorporate commercial fish size limitations and minimum mesh requirements, commercial quotas, de minimus specifications for quota allocation for states experiencing commercial landings of less than 0.1 percent of the total coastwide commercial landings in the last preceding year for which data was available, recreational size and possession limits as well as seasonal recreational limits and recreational harvest limits. A monitoring committee would review data on the fishery on an annual basis and submit recommendations to the management authorities regarding annual quotas, minimum take size, and minimum mesh size with respect to the commercial fishery and regarding possession and size limits and seasonal closures with respect to the recreational fishery. A framework adjustment process would be implemented to allow modification of management measures at any time during the year through a streamlined public review process. POSITIVE IMPACTS: The preferred alternative would eliminate overfishing and rebuild the bluefish stock through a graduated reduction in the fishing mortality rate. NEGATIVE IMPACTS: The quotas and other limitations set out in the amendment would cause economic hardships for some commercial operators.

Ozone laminae appear in the lower stratosphere soon after the polar vortex is established in autumn, increase in number throughout the winter and reach a maximum abundance in late winter or spring. We indicate a possible coupling between mid-winter, sudden stratospheric warmings (when the vortex is weakened or disrupted) and the abundance of ozone laminae using a 23-year record of ozonesonde data from the World Ozone Data Center in Canada combined with monthly-mean January polar temperatures at 30 hPa. Results are presented from an experiment conducted during the winter of 1994/95, in phase II of the Second European Stratospheric And Mid-latitude Experiment (SESAME), in which 93 ozone-enhanced laminae of polar origin observed by ozonesondes at different time and locations are linked by diabatic trajectories, enabling them to be probed twice or more. It is shown that, in general, ozone concentrations inside laminae fall progressively with time, mixing irreversibly with mid-latitude air on time-scales of a few weeks. A particular set of laminae which advected across Europe during mid February 1995 are examined in detail. These laminae were observed almost simultaneously at seven ozonesonde stations, providing information on their spatial scales. The development of these laminae has been modelled using the Contour Advection algorithm of Norton (1994), adding support to the concept that many laminae are extrusions of vortex air. Finally, a photochemical trajectory model is used to show that, if the air in the laminae is chemically activated, it will impact on mid-latitude ozone concentrations. An estimate is made of the potential number of ozone molecules lost each winter via this mechanism.

AN - 16353121; 6993 AB - PURPOSE: The designation of certain areas of Grand Bay, Point Aux Chenes Bay, and the Bangs Lake system and surrounding uplands in Mississippi as the Grand Bay National Estuarine Research Reserve (GBNERR) is proposed. Approximately 18,400 acres are included within the boundaries of the proposed site; approximately 75 percent of which are publicly owned. The proposed GBNERR would encompass 14,400 acres, consisting of a broad variety of estuarine and non-estuarine wetland habitats that together form a largely intact coastal watershed. The area was historically part of a larger delta associated with the Escatawpa River prior to the river's change of course and, as such, is characterized by a retrograding delta. The open-water estuarine areas support large, productive oyster reefs and seagrass habitats. The intertidal portion of the area includes a wide variety of representative marsh types (low-, mid-level, and high-elevation zones across a wide range of salinity) as well as some of the most extensive, unvegetated salt flats in this part of the Mississippi Sound. The non-tidal areas include wet pine savanna, coastal bayhead and cypress swamps, freshwater marshes, and maritime forests. Federal financial assistance for operation, management, and development of the GBNERR have been requested by the state of Mississippi for the reserve. Approval of the proposal would allow for establishment a reserve representing the Mississippi Deltaic subregion of the Louisianian biogeographic region. The reserve would be administered by the Mississippi Department of Marine Resources, primarily for research and educational purposes, particularly as a tool for improving coastal decision making. Traditional uses within the reserve (boating, fishing, hunting, shellfish harvesting, and camping and other recreational activities) would continue to be regulated by local and state laws and management policies. If approved, the GBNERR would be operated to address information needs of resource managers and the public identified as significant through coordinated estuarine research; promote federal, state, public, and private use of the reserve for research purposes; conduct and coordinate estuarine research within the reserve; gather and make available information necessary for improved understanding, use, and management of estuarine areas; and provide suitable opportunities for public education and interpretation. Alternatives under consideration in this draft EIS include the No Action Alternative, alternative sites, alternative boundaries, and alternative management options. Approval of the GBNEER as proposed is the preferred alternative. POSITIVE IMPACTS: The national estuarine research reserve designation and management would facilitate natural and cultural resource protection through long-term ecological research, environmental monitoring, environmental education, and resource stewardship. Educational programs would increase public awareness of estuarine resources and their importance. The research plan would establish a baseline monitoring program for the area and encourage research projects consistent with the reserve's role as a natural field laboratory. NEGATIVE IMPACTS: The repaving and/or widening of roads could adversely affect adjacent land uses. The denial of access for pipeline right-of-way within the reserve could adversely affect pipeline operators economically. LEGAL MANDATES: Coastal Zone Management Act of 1972 (43 U.S.C. 1241).

AN - 36411631; 6985 AB - PURPOSE: The designation as a National Estuarine Research Reserve (NERR) of a site in the Guana, Tolomato, and Matanzas River area (GTM) of Florida is proposed. Currently, there are two NERRs in Florida, the 200,000-acre Apalachicola NERR and the 10,000-acre Rookery Bay NERR, both of which are on the Gulf Coast. Through Florida's land acquisition program, nearly 100,000 acres of additional land are available for NERR status. The GTM, part of the temperate Carolinian biogeographic province (East Florida subregion), is located south of Jacksonville on the northeast coast of Florida. The area consists of a system of bar-bounded estuaries extending south from Jacksonville to below Marineland behind the barrier island system. The portion of the GTM proposed for designation covers approximately 31,595 acres of publicly owned uplands, tidal wetlands, estuarine lagoons, and offshore areas. The area is geographically separated into a northern section associated with the Tolomato and Guana River estuaries, and a southern section associated with the Matanzas River estuary. The areas are separated by the populated areas of Saint Augustine, Saint Augustine Beach, and Crescent Beach. More specifically, the area includes areas south of the City of Saint Augustine (including the sovereign submerged lands within Class II waters of the Matanzas River and the sovereign submerged lands classified as outstanding Florida waters and adjoining publicly owned uplands within the Pellicer Creek Aquatic Preserve), the Faver-Dykes State Park, the Washington Oaks State Gardens, the Flagler County Princess Place Preserve, the Fort Mantanzas National Monument, and the Saint Johns River Water Management District Moses Creek Conservation Area and adjoining publicly owned conservation uplands and areas north of the City of Saint Augustine (including all sovereign submerged lands and other state-owned lands within the Guana River Marsh Aquatic Preserve), and the Stokes Landing Conservation Area. The administration of the GTM as an NERR would involve the designation of advisory groups, cooperating mangers, and a staff including a reserve manager, research coordinator, education coordinator, and resource management coordinator. The stewardship action plan, designed to facilitate government and citizen involvement, would involve the formation of partnerships with other agencies and organizations actively involved in resource protection in the GTM NERR watershed. Management direction for the NERR would also incorporate land acquisition programs, and action plans for public access, research monitoring, volunteer participation, facilities construction, and education, interpretation and public outreach. In addition to the two designated sites, eight sites on Florida's Atlantic Ocean coast are considered for nomination, and two alternative programs and a No Action alternative are also under consideration in this draft EIS. POSITIVE IMPACTS: The NERR designation and management would facilitate natural and cultural resource protection through long-term ecological research, environmental monitoring, environmental education, and resource stewardship.

AN - 36414577; 6981 AB - PURPOSE: The establishment and implementation of fishery management plans (FMPs) for calico scallops and sargassum habitat in the South Atlantic region by the South Atlantic Fishery Management Council is proposed. The management area encompasses areas within the United States' territorial waters and the Exclusive Economic Zone (EEZ) of Florida, Georgia, North Carolina, and South Carolina. This draft EIS considers five actions for the calico scallop fishery and four actions for sargassum habitat. The proposed action for the calico scallop fishery of the South Atlantic region would identify essential fish habitat (EFH) and establish EFH-habitat areas of particular concern (EFH-HAPCs) for calico scallops. It would also establish a FMP for the calico scallop fishery of the South Atlantic region. It would also prohibit the harvesting of calico scallops in the area bounded to the west by 80 degrees longitude, to the north by 28 degrees 30 minutes north latitude, to the south by 27 degrees 30 minutes north latitude, and to the east by the 100 fathom (600 feet) depth contour. It would also require the use of transponders by calico scallop vessels either in the South Atlantic EEZ or in the South Atlantic EEZ south of 28 degrees 30 minutes north latitude. The proposed action for sargussum habitat of the South Atlantic region would identify EFH and establish EFH-HAPCs for sargassum. It would also establish a FMP for sargassum habitat of the South Atlantic region. It would also prohibit the harvesting and/or the possession of pelagic sargassum in the South Atlantic EEZ. POSITIVE IMPACTS: The measures would allow for the continued development of sustainable fisheries that target both inshore and offshore fishery resources. Overfishing would be prevented through the use of effective management controls as the fishery develops.

AN - 36413934; 6980 AB - PURPOSE: The amending of management regimes for various South Atlantic region fisheries by the South Atlantic Fishery Management Council is proposed. The management area encompasses areas within the United States' territorial waters and the Exclusive Economic Zone (EEZ) of Florida, Georgia, North Carolina, and South Carolina. This draft supplemental EIS considers amendments to the fishery management plans (FMPs) for shrimp, red drum, snapper grouper, coastal migratory pelagics, golden crab, spiny lobster, and coral, coral reefs, and live and hard bottom habitats of the South Atlantic region. Amendment 4 to the FMP for the shrimp fishery of the South Atlantic region would identify essential fish habitat (EFH) for penaeid and rock shrimp, and establish EFH-habitat areas of particular concern (EFH-HAPCs) for penaeid shrimp. It would also require the use of transponders by rock shrimp vessels fishing in the South Atlantic EEZ or in the South Atlantic EEZ south of 28 degrees 30 minutes north latitude. Amendment 1 to the FMP for the red drum fishery of the South Atlantic Region would identify EFH and establish EFH-HAPCs for red drum. Amendment 10 to the FMP for the snapper grouper fishery of the South Atlantic Region would identify EFH and establish EFH-HAPCs for species in the snapper grouper management unit. It would also prohibit all fishing within the experimental closed area. Amendment 10 to the FMP for the coastal migratory pelagics fishery of the South Atlantic Region would identify EFH and establish EFH-HAPCs for coastal migratory pelagics. It would also prohibit fishing in the experimental closed area. Amendment 1 to the FMP for the golden crab fishery of the South Atlantic Region would identify EFH and establish EFH-HAPCs for golden crab. Amendment 5 to the FMP for the spiny lobster fishery of the South Atlantic Region would identify EFH and establish EFH-HAPCs for spiny lobster. It would also prohibit fishing in the experimental closed area. Amendment 4 to the FMP for the coral, coral reefs, and live and hard bottom habitats of the South Atlantic Region would identify EFH and establish EFH-HAPCs for coral, coral reefs, and live and hard bottom habitats. It would also prohibit all fishing in the experimental closed area. It would also expand the Oculina Bank HAPC to an area bounded to the west by 80 degrees west longitude, to the north by 28 degrees 30 minutes north latitude, to the south by 27 degrees 30 minutes north latitude, and to the east by the 100 fathom (600 feet) depth contour. It would also expand the Oculina Bank HAPC by one to five miles on the western side between 27 degrees 30 minutes north latitude and 28 degrees 30 minutes north latitude. POSITIVE IMPACTS: The measures would allow for the continued development of sustainable fisheries that target both inshore and offshore fishery resources. Overfishing would be prevented through the use of effective management controls as the fishery develops. NEGATIVE IMPACTS: The use of transponders would meet with some resistance from industry groups due, in part, to the cost of installing the devices. Fishing operators harvesting in areas to be closed would suffer some economic losses. LEGAL MANDATES: Fishery Conservation and Management Act of 1996 (P.L. 104-208).

AN - 62481448; ED421968 AB - Findings of this report indicate that, since an earlier 1994 study, the number of Americans that own computers has increased by over 50% and the number of households using e-mail has quadrupled. Nevertheless, access to the Information Superhighway is still beyond the grasp of many Americans. While the nation-wide telephone penetration rate remains at a relatively high level of 93.8%, some pockets of Americans still have no telephone service. Whites still have a far higher telephone penetration rate (95.9%) than Blacks (86.0%) and Hispanics (86.5%). There are even more disparities in computer ownership and access to online services. Although more Americans now own computers than before, households earning more than $75,000 are approximately seven times as likely to own a computer as those earning between $5,000 and $10,000. White households are still more than twice as likely (40.8%) to own a computer than Black households (19.3%) or Hispanic households (19.4%). These gaps in ownership levels are greater than they were three years ago. Findings underscore the importance of such programs as NTIA's Telecommunications and Information Infrastructure Assistance Program and the E-Rate (a program that will allow schools and libraries to establish Internet connections at discounted rates). Twenty-four charts illustrate statistics.

This hydrothermal helium signal is especially strong in the Pacific Ocean, where the spreading rate of the ridges is the greatest. In several areas of the Pacific the hydrothermal activity is of sufficient strength to produce intense helium plumes which clearly define the regional circulation. Among these are (1) a pair of helium plumes at 2500-m depth, which extend westward from the East Pacific Rise at 10 degrees N and 15 degrees S into the interior of the Pacific basin; (2) a helium plume at 2000-m depth extending southwest from sources on the Juan de Fuca Ridge in the northeast Pacific; and (3) a plume at 1100-m depth emanating from Loihi Seamount at 20 degrees N, which extends eastward from Hawaii to the coast of Mexico. The flow field implied by the helium distribution appears to be in reasonable agreement with Reid's [1997] steric height analysis for the Pacific. Copyright 1998 by the American Geophysical Union.

Part II: Inundation mapping using dynamic streamflow modelling AN - 18006468; 4756540 AB - Since the first River Forecast Centers of the National Weather Service (NWS) were established in the mid-1940s, hydrological forecasts of flood crests have been issued for a specific location (coincident with a stream gauge) at a given point on a river or stream. The forecasts typically extended for three days into the future or until an expected flood crest was reached. The forecasts were deterministic and future precipitation was assumed to be negligible from the time the forecast was issued until the time the crest was forecast to occur. Each flood forecast was related to a predetermined flood stage where damage would occur in the reach surrounding the forecast point. These forecast products were issued as single point values for an expected time when the crest might occur. The catchment areas affecting these forecast points were generally large, in the order of thousands of square kilometres. In later years, the number of hydrological forecast points increased and the hydrological (rainfall-runoff) forecast areas have become increasingly smaller, 500 to 1000 km super(2). End users of these forecasts have been seeking more detailed information, including probabilistic forecasts from days, to weeks, to months into the future. They are also asking for enhanced forecast information which provides additional information regarding the flow conditions between forecast points, especially within urban areas. In order to provide such enhanced forecast services the National Weather Service (NWS) is implementing an Advanced Hydrological Prediction System (AHPS) which has been under development for several years and was recently demonstrated.

Part I: Ensemble generated probabilistic forecasts AN - 17680158; 4756539 AB - Floods are the leading weather related hazard throughout the world. A review of the world's recent and prominent flooding events reminds us that major floods will continue to occur and are devastating. Preparedness for these events can lead to saving lives and property. Within the United States of America alone, floods cause an average of $3.6 billion in damages and 139 lost lives annually; over 75% of the Presidential disaster declarations for the USA are in response to flooding events. It is therefore important to make the mitigation of this hazard a high-priority task. The USA weather programme has been providing river and flood forecasts for the public since 1890. This programme is managed by the US Department of Commerce, National Oceanic and Atmospheric Administration (NOAA), National Weather Service (NWS). Within the NWS, each of its 13 River Forecast Centers (RFCs) typically issue stage forecasts for only one, two and three days into the future at most forecast points and crest forecasts out to about one week for a few selected forecast points. These forecasts have been provided primarily for the protection of life and property in the vicinity of rivers. They have also been used for the assessment of extended drought scenarios. Droughts, while generally not life-threatening in the USA, have a serious impact on agriculture, ecosystems and water management, and the economy in general. This chapter, which is in two parts, describes an advanced real-time hydrological forecasting procedure which provides more accurate forecasts with long warning times. A significant feature of the system is its application of meteorological and climate (months to seasonal) predictions for the improvement of real-time hydrological forecasts. The system described was demonstrated operationally for the Des Moines River basin in March 1997.

N1 - Last updated - 2011-12-13 ER - TY - JOUR T1 - Recruitment of larval fishes into a North Carolina estuary during a bloom of the red tide dinoflagellate, Gymnodinium breve AN - 17160820; 4452222 AB - An unprecedented bloom of the toxic dinoflagellate Gymnodinium breve in coastal waters of North Carolina occurred during year three (fall-winter 1987-1988) of an eight-year larval fish study. This event was the basis for examining the possible effects of red tide on the estuarine recruitment of nine species of larval fishes. Densities of larvae for 1987-1988 were compared to their corresponding average densities for the two seasons prior to and five seasons after the red tide. Larval fish recruitment for most species over the entire 1987-1988 season was not unusually low, although two of nine species did exhibit their 8-yr minima during this time. Densities for 1987-1988 were compared with the densities averaged (by week) over the other 7 yrs and revealed three general patterns of response. Two species, Paralichthys albigutta (gulf flounder) and Citharichthys spilopterus (bay whiff) had consistently low densities throughout their normal period of recruitment, suggesting that their estuarine recruitment may have been impacted by the effects of G. breve even after the bloom ended. In contrast, Micropogonias undulatus (Atlantic croaker) and Lagodon rhomboides (pinfish) densities were generally normal, or above normal, both during the bloom and for the remainder of the larval recruitment season. Five other species (Brevoortia tyrannus, Atlantic menhaden; Paralichthys lethostigma, southern flounder; Leiostomus xanthurus, spot; Mugil cephalus, striped mullet; Myrophis punctatus, speckled worm eel) had low densities during the bloom, but increased markedly later in the season. This pattern suggested these five species suffered immediate effects when the red tide was extant, but had high recruitment success later in the season. In the first post-red tide year, six of the nine species had their highest mean catches over the first 14 wks of all 8 yrs and suggested a possible post-red tide beneficial effect on larval fish estuarine recruitment.

The results of a shipboard line-transect survey conducted in July-November 1991 ("summer") were compared to those from aerial line-transect surveys conducted in March-April 1991 and February-April 1992 ("winter"). Using a confidence-interval-based bootstrap procedure, abundance estimates for six of the eleven species included in the comparison exhibited significant ( alpha = 0.05) differences between the winter and summer surveys. Pacific white-sided dolphins (Lagenorhynchus obliquidens), Risso's dolphins (Grampus griseus), common dolphins (Delphinus spp.), and northern right whale dolphins (Lissodelphis borealis) were significantly more abundant in winter. The abundance of blue whales (Balaenoptera musculus) and gray whales (Eschrichtius robustus) reflected well-documented migratory patterns. Fin whales (B. physalus) were significantly more abundant during summer. No significant differences in seasonal abundance were identified for Dall's porpoises (Phocoenoides dalli), bottlenose dolphins (Tursiops truncatus), killer whales (Orcinus orca), sperm whales (Physeter macrocephalus), or humpback whales (Megaptera novaeangliae). Significant north/south shifts in distribution were found for Dall's porpoises, common dolphins, and Pacific white-sided dolphins, and significant inshore/offshore differences were identified for northern right whale dolphins and humpback whales.

In shipboard line-transect surveys binocular reticles are used to obtain estimates of radial distance from the ship to animals. From shore-based platforms both binocular reticles and theodolites are used to measure distances for determining spatial distributions and dive patterns of coastal animals. In aerial line-transect surveys inclinometers or angle markings on observation windows or wing struts are used to determine perpendicular distances from sightings to the trackline. In this note we present formulae which take into account the curvature of the earth for converting the angular readings from these instruments to the desired distance values. These formulae are then compared with approximations that have been used in the analysis of marine mammal survey data. The extent to which these approximations diverge from the distance formulae presented here is identified. The presented formulae have been used by researchers in marine mammal science in the past. The purpose of this note is to present them in the context of marine mammal surveys from various platforms.

The bluefish Pomatomus saltatrix is an oceanic spawner whose juvenile stages, upon entry into estuarine waters, become piscivorous and thereby experience greatly increased growth. Size attained during the growing season may therefore be determined by time of arrival into estuarine habitats. We exposed bluefish recently recruited to an estuary to three diet shift treatments in which test fish were fed adult brine shrimp Artemia sp. for 0, 10, or 20 d before they were switched to piscine prey. Bluefish that had a delayed onset of piscivory were smaller after 40 d of growth, indicating that they did not fully compensate for prior periods of slow growth. These bluefish did exhibit immediate moderate growth compensation (about 6% over 10 d) resulting from increased consumption rates, but relatively low growth efficiencies prevented full recovery of their growth losses. Low growth efficiencies may have resulted from an induced developmental handicap or an energetic penalty for prolonged feeding on an Artemia diet. The timing of age-0 bluefish recruitment into estuarine environments can have a lasting influence on size attained during the first growing season.

Tag-recovery data support a two-population hypothesis throughout the North American range: an Alaska population ranging from the Bering Sea, including the Aleutian Islands and extending down through the Gulf of Alaska to northwest Vancouver Island, Canada; and a west coast population extending from southwest Vancouver Island to Baja California. Tag recoveries indicate that these two populations mix off southwest Vancouver Island and northwest Washington, and to a lesser extent off southern Washington and Oregon. Alaska sablefish, which commonly migrate over 500 n mi, are more mobile than west coast sablefish. Tag recoveries for sablefish tagged in Alaska have shown strong mutual exchanges between nearly all areas. In contrast, west coast sablefish have shown far less migratory behavior. Tagging data with respect to bathymetry are difficult to interpret in both regions owing to the fact that tagging and recovery effort do not cover the full bathymetric range of adults. Results of analysis of tag-recapture growth data were consistent with patterns observed for several other pelagic and demersal species. That is, El Nino-Southern Ocean Oscillation events appeared to retard the growth of sablefish along the west coast and to enhance growth of Alaska sablefish. The timing of recoveries from sablefish tagged off Alaska and recovered off southwest Vancouver Island and Washington-Oregon suggests that movement south correlates positively with strong upwelling in this southern area. Although sablefish trap-index surveys show a north to south cline in the percentage of large sablefish (>60 cm, and possibly of Alaska origin) sampled in length frequencies along the west coast, we were unable to correlate annual fluctuations in these percentages with upwelling strength.

Tagging records were analyzed to determine the species composition, population structure, and seasonal occurrence of Kemp's ridley, Lepidochelys kempii, loggerhead, Caretta caretta, and green, Chelonia mydas, turtles. Additional information on local movements, morphometrics, growth, population estimation, and diet was provided for Kemp's ridley turtles. Subadult green turtles dominated the catch on the seagrass shoals of Waccasassa Reefs. Subadult Kemp's ridley turtles and, to a lesser degree, subadult and adult loggerhead turtles were primarily captured near the oyster bars of Corrigan Reef. Marine turtles were caught in these nearshore waters from April to November. Recaptures indicate that some Kemp's ridley turtles remain in the vicinity of Corrigan Reef during their seasonal occurrence and return to this foraging area annually. Seasonal and annual size distributions of Kemp's ridley turtles were investigated and regression equations were developed for carapace morphometrics. Carapace growth averaged 4-5 cm/yr for Kemp's ridley turtles, but growth analyses were confounded by the extrapolation of annual estimates from short-term recaptures. Population estimates for the Kemp's ridley mark-recapture data indicated a mean annual population size of 159 turtles at Corrigan Reef with presumably high rates of immigration and emigration by larger subadult turtles. Examination of fecal samples indicated that crabs were the primary food items of Kemp's ridley turtles captured near oyster bars.

Gag were randomly sampled from 1991 through 1993 (n=1398) and selectively sampled with a bias towards heavily pigmented fish in 1994 (n=648). All samples were taken from commercial and recreational fisheries in the northeastern Gulf of Mexico. Sex ratio was 49 females: 1 male for the 1991-93 samples. Heavily pigmented gag (n=62), commonly thought to be males, were collected from waters >41.0 m during all months except January and March. Of these, 60 were histologically sexed and found to be 5.0% female, 3.3% possibly early transitional male, and 91.7% male. Indeterminate spawning generally occurred from February through April in water depths >30.5 m. Hydrated oocytes were homogeneously distributed in hydrated ovaries. Shortest length and youngest age at spawning were 577 mm total length (TL) and 3 years for females, and 981 mm TL and 8 years for males. The highest batch fecundity (865,295 hydrated oocytes) occurred in an 8-year-old, 1038-mm-TL gag. Batch fecundity had a significant ( alpha =0.01) positive correlation with TL, gutted body weight, and age but was most strongly correlated with TL. Average annual spawning frequency ranged from 8 to 27 for 2- to 9-year-old fish, varying significantly by year (P<0.05) and among years and age classes (P<0.02). Annual fecundity estimates ranged from 0.065 to 61.4 million and correlated well with age.

Yellowfin sole were most concentrated nearshore; abundance gradually decreased with increasing bottom depth to trace numbers beyond 100 m. Male yellowfin sole were distributed nearer to shore than females in all years.. Proportions of males (no. males/no. both sexes), therefore, increased nearshore with decreasing bottom depth. Males outnumbered females by two to one in waters less than 30 m deep. Yellowfin sole during 1982-84 were distributed in deeper waters than during 1985-96. The shallower distributions after 1984 were attributed to greater percentages of mature fish that reside in nearshore spawning areas (3 million metric tons) during 1982-84 were attributed in part to increased availability of yellowfin sole within the standard survey area.

The purpose of this paper is to address the role of the large-scale flow on low-level cyclone/frontal structure and evolution through a combined observational and idealized modeling approach. Analyses of two observed cyclone cases embedded in large-scale diffluence and confluence, respectively, are presented to illustrate two possible cyclone/frontal structures and evolutions. Specifically, the cyclone moving into a diffluent, high-amplitude ridge becomes meridionally elongated and possesses a strong meridionally oriented cold front and a weak warm front. The cold front rotates into the warm front, forming an occluded front in the manner of the Norwegian cyclone model, as indicated by the narrowing of the thermal ridge connecting the warm sector to the cyclone center. In contrast, the cyclone moving into confluent, low-amplitude zonal flow becomes zonally elongated and possesses strong zonally oriented warm and bent-back fronts and a weak cold front. The frontal structure in this case is reminiscent of the Shapiro-Keyser cyclone model, exhibiting a fracture between perpendicularly oriented cold and warm fronts (i.e., the so-called frontal T-bone structure). The idealized simulations employ a nondivergent barotropic model in which potential temperature is treated as a passive tracer. When a circular vortex acts on an initially zonally oriented baroclinic zone, cold and warm fronts, a frontal fracture, a bent-back front, and eventually a Norwegian-like occlusion develop. When a circular vortex is placed in a diffluent background flow, the vortex and frontal zones become meridionally elongated, and the evolution resembles the Norwegian occlusion with a narrowing thermal ridge. When a circular vortex is placed in a confluent background flow, the vortex and frontal zones become zonally elongated, and the evolution resembles the Shapiro-Keyser model with a frontal fracture, frontal T-bone, and bent-back front. Although the idealized model qualitatively reproduces many of the frontal features found in the observed cyclones analyzed in the present study, one significant difference is that the maximum potential temperature gradient and fronto-genesis along the cold and warm fronts may differ by a factor of 2 or more in the observed cases, but remain equal along the cold and warm fronts throughout the idealized model simulations. Possible reasons for this asymmetry in the strength of the observed cold and warm fronts are discussed.

Forecast precipitation fields, although not perfect when compared to the observations of rainfall, appear to have sufficient information to be considered useful forecasting guidance. The results illustrate that a good simulation for this type of event in a region with complex topography is strongly dependent on a good initialization and prediction of the low-level flow and water vapor distribution. For two of the cases that have a marked synoptic-scale contribution, the simulations give reasonably accurate predictions of the precipitation distribution, although the amounts are generally underestimated. The third case exhibits relatively subtle synoptic-scale forcing and is dominated by isolated convective storms (mostly over the sea) that also produced severe thunderstorms (including tornadoes), and the prediction of precipitation is not as promising. Overall, the results are encouraging in terms of potential application of mesoscale models operationally in the western Mediterranean region. Additional experiments beyond the "control" simulations have been performed to isolate the influence of orography and water vapor flux from the Mediterranean Sea on the model simulations. This factor separation indicates that both effects can be important contributors to a successful forecast. Suggestions are offered for future efforts in pursuing the application of mesoscale models to this forecast problem.

The stomach contents of harbor porpoises killed in groundfish gill nets in the Gulf of Maine from September-December, 1989-94 were analyzed. Frequency of occurrence, numerical proportion, and proportion of ingested mass for Atlantic herring, pearlsides, silver hake, and red and white hake are reported. Calf diets differed significantly from those of adults in the number of herring eaten and the total mass of food eaten, but otherwise there were no major differences in diet by maturity or gender. Further studies are needed on seasonal shifts in harbor porpoise diets and movements to understand the causes of porpoise entanglement in gill nets and offer insight into potential mitigative measures.

Visual surveys conducted by divers from 1979-96 were used to estimate population abundance, assemblage composition, and stock structures in relation to habitat factors. An algorithm for calculating total mortality rates from exploitable phase fish average length estimates is explained. A reef fish equilibrium exploitation fishery simulation model was developed to take fishing mortality estimates as input and to generate yield-per-recruit data in relation to fishing intensity and gear selectivity, and spawning potential ratios in relation to federal overfishing standards. Some 23 species are below the 30% overfishing minimum. Depletion of the largest, most desirable, and most vulnerable reef fish species is typical of serial overfishing.

A case study is described in which a wild dolphin was observed trailing a long, large clump of tangled fishing line wrapped around the tail flukes and peduncle. After several days, the dolphin permitted researchers to cut the line. Continued observation showed deep scarring, indicating that the flukes could have been severed had the line not been cut. Other research has documented entanglement in discarded monofilament line as a contributing factor in the death of several dolphins in the bay. The importance of mortality and serious injury to dolphins from recreational fisheries needs to be studied further.

The toxicity of OTC to elasmobranchs is unknown; if its effects on health and growth of treated fish is significant, its use as a chemical marker may be compromised. The effect of OTC treatment on the growth rate and health of captive nurse sharks were studied. Serologic and hematologic observations, as well as growth measurements and necropsies, indicated that growth rates between control and OTC groups were not significantly different. For the most part, serologic and hematologic chemistry also was not significantly different between the groups. OTC does not appear to produce short-term effects on nurse sharks that might complicate age validation. But minor evidence suggests potential hepatotoxic effects over long time periods.

Genetic variation in Chionoecetes bairdi and C. opilio in exploited populations in Alaska was studied to determine if enough differentiation exists to warrant re-examination of current management units. Allozyme electrophoresis data were used to estimate allele frequencies, average observed heterozygosities, and genotype frequencies, from which the degree of population subdivision was calculated. Low levels of geographic differentiation were found among populations of both species. Some of the data suggest that subpopulations of C. bairdi exist in the Bering Sea. Some gene transgression between C. bairdi and C. opilio also was observed. When a North Atlantic C. opilio was compared with the Pacific crabs, little differentiation and no private alleles were detected.

Catch rates for the six most abundant species peaked in the early 1980s, declined by a factor of more than 100 to a low in 1984, and generally have remained low through 1993. One species has not been taken since 1984. Comparison of data from the King Harbor station with scuba transect data suggest that impingement data accurately reflect rockfish abundances in this area. Decreased recruitment success due to long-term adverse oceanographic conditions and overfishing probably are responsible for the drop in rockfish abundance.

Under high temperature hypoxic conditions, sturgeon survival declined to a mean of 6.3% and respiration rates dropped to a mean of 0.136 mg oxygen/g-h. Under low temperature hypoxia, survival was 78% and mean respiration rates were 0.212 mg O sub(2)/g-h. Growth rates diminished significantly under both conditions when sturgeon were denied access to the surface. Hypoxia probably has degraded sturgeon nursery habitats in Chesapeake Bay, preventing sustained recovery of sturgeon stocks.

The investigation of the variabilities and correlation of O sub(3) and CO presented here indicates that the seasonal cycles of the medians and the means of O sub(3) and CO are qualitatively similar to the cycles observed at other northern midlatitude sites. The signature of O sub(3) produced from anthropogenic precursors is clearest in the spring at the Azores and in the summer at Sable Island. The influence of the natural stratospheric O sub(3) source is apparent at Sable Island, particularly in the spring. At all sites the variability of CO throughout the year is dominated by episodes of pollution transport. The slopes of the monthly O sub(3)-CO correlations in the summer in Atlantic Canada and the spring in the Azores are quite uniform at 0.3 to 0.4. However, individual pollution transport events often have larger ( less than or equal to 1.0) slopes, which indicate significantly different net O sub(3) production efficiencies between episodes. The average slope of O sub(3) versus CO at Sable Island in the winter for moderate pollution transport events (CO less than or equal to 180 ppbv) is -0.28, which indicates that the titration of ambient O sub(3) by emitted NO with little if any photochemical O sub(3) production dominates the O sub(3) chemistry over eastern North America in winter. Diurnal cycles driven by photochemistry are observed in the summer for both O sub(3) and CO at the Azores (net loss) and Sable Island (net production.) These observations are consistent with the work of Duderstadt et al. who find positive net photochemical O sub(3) production at Sable Island, and with the modeling of Atherton et al. who find a region dominated by photochemical loss of O sub(3) and CO in the central Atlantic.

The model is tested by comparisons of the results with observations obtained at two ground stations in Nova Scotia, Canada, and on board two aircraft. The modeled mixing ratios of CO and O sub(3) as well as the ratio of Delta O sub(3)/ Delta CO at the two ground sites are in satisfactory agreement with the observations. More than 90% of the aircraft-observed O sub(3) and CO and 75% of NO sub(y) can be reproduced by the model with relative differences less than 50 and 100%, respectively. The model-simulated correlations among O sub(3), CO, and NO sub(y) are close to the aircraft observations. Most of the model-calculated vertical distributions of these species have the same pattern as the observations. The calculated profiles coincide with the observations with mean discrepancies of about 25, 30, and 100% for O sub(3), CO, and NO sub(y), respectively. The model-calculated wind speeds are in good agreement with the observations. Continental plumes within the model may be spatially off by a few hundred kilometers or temporally off by several hours. Possible inaccuracy in side boundary conditions and some difficulties in capturing small scale processes like small scale intrusion from the stratosphere and subgrid scale convective mixing are possible explanations for discrepancies between chemical data and model results.

AN - 36413822; 6963 AB - PURPOSE: The implementation of a management plan for the Atlantic herring fishery by the New England Fishery Management Council is proposed. The management unit is defined as all Atlantic sea herring within United States territorial waters and the Exclusive Economic Zone (EEZ). The herring resource is under-exploited state. Estimated of current stock size are based on the most recent fully reviewed assessment, which estimated the 1994 three-plus biomass at a record level of 3.6 million metric tons (MT); the estimate for spawning stock biomass (SSB) was 2.1 million MT. The estimated maximum sustainable yield (MSY) for the Atlantic herring coastal stock complex is 317,000 MT (including the Canadian Georges Bank and New Brunswick harvests). Of this estimate, the Gulf of Maine (GOM) spawning component is believed to be capable of providing a long-term potential yield of 80,000 MT (including the New Brunswick juvenile catch). While these estimates of large exploitable biomass have increased commercial interest in the development of the herring fishery, there are concerns that specific spawning components (notably the GOM component may not be able to sustain current or increased fishing pressure over the long-term. The maximum fishing mortality established by the plan is F=0.30. The minimum biomass level is established as 50 percent of the biomass at MSY (approximately 500,000 MT). The management plan would establish a target fishing mortality of 0.28 when total biomass exceeded biomass at MSY. When biomass fell below biomass at MSY, the target fishing mortality would be based on a five- to ten-year rebuilding schedule. Several alternatives, including a No Action alternative, are considered in this draft EIS. Management measures considered would include the adoption of a total allowable catch (TAC) and the distribution of the TAC across time and area, the closure of the fishery in an area when the TAC was reached, effort controls to limit catches as a TAC was approached, a requirement that licensed vessels and dealers be subject to mandatory data reporting, the implementation of effort controls, restrictions on the size of vessels allowed in the fishery, a series of spawning area restrictions, options for a controlled access system, restrictions on the use of herring, possible restrictions on joint venture processing activities, and a permit system for all participating vessels, operators, and dealers. POSITIVE IMPACTS: The measures would allow for the orderly development of a sustainable fishery that targets both the inshore and offshore herring resource. Overfishing would be prevented through the use of effective management controls as the fishery develops. An annual scientific review of the status of the resource would allow for adjustments to the fishery as a result of fluctuations in stock size. NEGATIVE IMPACTS: Some objectives could prove to be economically incompatible. Spawning area restrictions would increase fishing costs and reduce the value (fat content) of fish taken, as it is during spawning that fish aggregate and contain the greatest fat volume.

AN - 36411321; 6962 AB - PURPOSE: The amending of the management plan for the sea scallop fishery of the Atlantic Ocean by the New England Fishery Management Council is proposed. The management unit consists of sea scallop resources from the shoreline to the outer boundary of the Exclusive Economic Zone (EEZ). The overall objectives of the original management plan, implemented in May 1982, are to restore adult sea scallop stock abundance and age distribution; to increase yield per recruit for each stock; to evaluate plan research, development, and enforcement costs; and to minimize adverse environmental impacts on sea scallops. This draft supplement to the final EIS of May 1982 considers changes to the way Atlantic sea scallops are managed. The objective is to reduce fishing mortality in the EEZ to prevent overfishing of scallops and to rebuild the Atlantic scallop stocks to a level that will produce the maximum sustainable yield on a continuing basis. Alternatives with seven- and ten-year time frames are under consideration along with the continuation of the current regime (the No Action Alternative). Each time frame would incorporate different annual fishing mortality targets. Under the preferred alternative (a ten-year schedule), substantial reductions in fishing would be enforced. In addition to the analysis of the time frames for the rebuilding program, this draft supplemental EIS presents four management options for achieving the fishing mortality reduction targets. Management options would include a reduction in the number of days-at-sea (DAS) for the limited access scallop fishery, the closure of areas, bycatch reduction measures, and other measures that would be implemented through the framework adjustments process. All options would specify DAS limits. Option A would specify no measures designed to increase the size of scallops caught. Option B would substitute areas closures for 25 percent of the annual DAS reductions. Option C would enforce additional measures to increase the size of scallops caught (partial recruitment) to larger than 90 millimeters (mm) in shell height by the year 2006. Option D would enforce additional measures to increase the size of scallops caught to larger than 90 mm in shell height by the year 2000. The Council could implement any of these options, but any measures requiring additional area closures or opening any part of the groundfish areas closed to scallop fishing would have to be implemented through a framework adjustment after the plan was approved. In other words, the DAS reductions would constitute the only measures that could be implemented under any of these options until the Council submits a framework adjustment that included the other measures under Option B, Option C or Option D. POSITIVE IMPACTS: The amendment would reduce the current rate of fishing mortality, which is unacceptably high, and provide for flexibility in dealing with dynamic fishery conditions. NEGATIVE IMPACTS: The imposition of DAS and other controls would restrict the immediate commercial capacity of the fishery, causing short-term economic hardships for some users. Some jobs would be lost if vessels excluded from the scallop fishery did not switch to an unregulated species. The preferred alternative would result in lower calculated net economic benefits than the other action alternative considered.

A version of the RELMAP mercury model is used which separately simulates the transport and deposition of emissions from the seven point-source categories modeled. A mercury air emission inventory developed by the U.S. EPA Office of Air Quality Planning and Standards for the continental United States is used. This inventory provides estimates of the total mercury mass emitted, but does not define the chemical and physical forms of these emissions. A wide variety of emission speciations, combinations of chemical and physical forms, are evaluated with the new RELMAP mercury model. Average annual concentrations and wet and dry deposition totals are simulated for a complete calendar year. The results of the simulation are used to estimate the quantity of mercury deposited to soils and water bodies based on a variety of assumed emission speciation for the seven point-source types. An analysis of the modeling results provides some quantitative information about the sensitivity of modeling results to uncertainty in the mercury emissions speciation of modeled industrial activities, but a qualitative assessment is the primary goal. The model is shown to be most sensitive to mercury emissions speciation uncertainty related to the burning of waste materials and electrical power generation.

AN - 36416866; 6941 AB - PURPOSE: The production of oil by BP Exploration (Alaska) Inc. (BPXA) from the Northstar Unit offshore of the Point Storkersen area in the Alaskan Beaufort Sea is proposed. BPXA's action would involve a self-contained offshore development and production facility located on a gravel island in 39 feet of water. Five alternatives, including a No Action Alternative (Alternative 1), are considered in this draft EIS. Under BPXA's proposed action (Alternative 2), the island would be constructed over the remains of Seal Island, built by Shell Oil Company to conduct exploratory activities within the Northstar Unit during the 1980s. Two pipelines buried in a single trench, extending from Seal Island to existing onshore facilities, would transport hydrocarbons to and from the Northstar Unit. The pipelines include a 10-inch common carrier pipeline from Seal Island to Pump Station Number 1 to transport sales quality oil to the Trans-Alaska Pipeline System and a second 10-inch pipeline to transport high-pressure gas from the Central Compressor Plant in the Prudhoe Bay Unit to Seal Island to assist with the gas cycling process used to deplete the Northstar reservoir. BPXA determined that the Northstar Unit contains approximately 145 million barrels of recoverable, high quality crude oil. The production facilities on Seal Island would be designed to produce up to 65,000 barrels of crude oil and 500 million standard cubic feet of natural gas per day. The facilities would include 15 producing wells, seven gas injection wells, and either one or two Class I waste disposal wells. Approximately 700 to 800 tankers trips per year departing the Valdez marine terminal are required to accommodate current North Slope production; the production of reserves from the Northstar reservoir would require the operation of additional tankers from the Valdez terminal. Over the life of the project, approximately 181 to 198 additional tanker trips would be required. All of the action alternatives would include the same offshore development and production facility; the differences distinguishing the action alternatives involve routing and other aspects of the pipeline system. The preferred alternative (Alternative 5) would use a pipeline buried within a causeway rather than a trench and a landfall at West Dock. The Northstar project would be the first offshore oil and gas development and production facility in the Alaskan Beaufort Sea without a causeway to shore and the first to include a connection to onshore facilities by a buried subsea pipeline. The risks of oil spills from the offshore island and the pipeline system exposed to ice hazards demanded in-depth analysis. Moreover, response limitations for oil spills under sea ice or in broken ice, and concerns regarding effects of such spills, also required attention. Finally, the effects of long-term year-round offshore oil and gas development and production activities, particularly noise emissions, are of particular concern with respect to their impact on subsistence activities. The life of the Northstar Unit development would extend approximately 15 years. POSITIVE IMPACTS: Oil produced by the Northstar Unit would help satisfy meet national energy requirements, and the development and production activities would employ 730 workers during construction and 25 workers during the life of the project. The project would contribute $520 million in gross state revenues. NEGATIVE IMPACTS: Alternative 5 would result in 3.1 miles of onshore pipeline on currently undeveloped land. Helicopter maintenance of the pipeline would disturb wildlife, particularly brand nesting areas. Noise and activity associated with the operation of the Seal Island facility, and related vessel transport operations, could result in bowhead whale avoidance response during migration periods, potentially adversely affecting subsistence hunting activities. The project facilities would mar area aesthetics. Alternative 5 would present a risk of 19 percent of a large oil spill (greater than 1,000 barrels).

AN - 36395079; 6940 AB - PURPOSE: The establishment of a Marine Conservation District (MCD) in association with the fishery management plan (FMP) for corals and reef-associated plants and invertebrates in the waters of Puerto Rico and the U.S. Virgin Islands is proposed. Coral reefs are among the most productive tropical marine systems, and form the backbone of the ecosystem's food chain. The existing FMP, established in 1996 by the Caribbean Fishery Management Council (CFMC), was prepared to establish a management system for coral reef resources within the Exclusive Economic Zone (EEZ) and the waters under the authority of the Commonwealth of Puerto Rico and the Territory of the U.S. Virgin Islands from the shoreline to the edge of the insular platform. It prohibits the harvest or possession of stony corals, sea fans, gorgonians, or any species in the fishery management unit if attached to, or existing upon life rock; prohibits sale of possession of any prohibited species unless imported and fully documented as to the point of origin outside the EEZ, prohibits the use of chemicals, plants or plant derived toxins, or explosives for harvest; and restricts harvesting of other invertebrates to dip nets, slurp guns, hand capture or other non-habitat descriptive methods. Presently, the CFMC is proposing the MCD, a measure that was reserved under the FMP; the MCD would be located in EEZ waters surrounding the Virgin Islands. An MCD is a discrete geographical area of special value and significance to the marine ecosystem that is to be maintained in its natural state. The purpose of the MCD is to conserve and manage representative samples of marine habitats and ecosystems and to maintain marine biodiversity. In addition, MCDs are established for the protection, conservation and arrangement of economically important species. The criteria for determining the geographic location of an MCD include ecological values (diversity of species, endangered species habitat, uniqueness of the area, representative ecosystem, importance to commercial species, and maintenance of natural areas), economic values (traditional fishery location, snorkel and dive opportunities, charter boat anchorage opportunities, attractiveness to tourists, and watershed management), and social values (cultural significance, recreational value, aesthetics, educational opportunities, and research opportunities). Alternatives under consideration include three options, the establishment of a no-take MCD in the area known as Hind Bank southwest of Saint Thomas (Option A and Option B), the establishment of a no-take MCD due south of Saint John (Option C), and a No Action Alternative (Alternative D). POSITIVE IMPACTS: The MCD establishment would provide refuge and replenishment areas to ensure continued abundance and diversity of reef resources; protect critical spawning stock and recruits from depletion and overfishing, thereby increasing the abundance of fishery resources; protect coral and coral habitat; and improve opportunities for eco-tourism. NEGATIVE IMPACTS: Certain individuals engaged in the harvesting and sale of commercially-important fish species would be adversely affected in the short-term.

Research into future climate change and the development of remedial environmental policies therefore require a reliable assessment of the long-term growth rate in the atmospheric methane load. Measurements have revealed that although the global atmospheric methane burden continues to increase with significant interannual variability, the overall rate of increase has slowed. Here we present an analysis of methane measurements from a global air sampling network that suggests that, assuming constant OH concentration, global annual methane emissions have remained nearly constant during the period 1984-96, and that the decreasing growth rate in atmospheric methane reflects the approach to a steady state on a timescale comparable to methane's atmospheric lifetime. If the global methane sources and OH concentration continue to remain constant, we expect average methane mixing ratios to increase slowly from today's 1,730 nmol/mol to similar to 1,800 nmol/mol, with little change in the contribution of methane to the greenhouse effect.

AN - 73913788; 9747518 AB - Since their invasion into the Great Lakes, zebra mussels, Dreissena polymorpha, have increased the water clarity in Lake St. Clair and Lake Erie due to their extensive particle filtration. Because these particles contain sorbed contaminants, the potential for contaminant accumulation from both suspended sediment and algae were examined. Sediment or algae were dosed with selected radiolabeled polycyclic aromatic hydrocarbon congeners and/or hexachlorobiphenyl (HCBP). Assimilation efficiencies were measured and depended on food quality. Zebra mussels, 17 +/- 2 mm long, assimilated 58.3 +/- 13.5% of the pyrene and 44.7 +/- 5.8% of the benzo(a)pyrene (BaP) from sediment particles with a particle clearance rate of 493-897 ml/g tissue/h. However, assimilation efficiencies were 91.7 +/- 3.7% for pyrene, 91.9 +/- 1.4% for BaP, 96.6 +/- 1.4% for chrysene, and 97.7 +/- 0.5% for HCBP from suspended algae. Algal particle clearance rates for the mussels ranged from 47-143 ml/g tissue/h. Thus, zebra mussels efficiently accumulated non-polar contaminants sorbed to algae, while a smaller fraction of the sediment-associated contaminant was bioavailable. Furthermore, the contaminants sorbed onto suspended sediment particles were quickly removed from the water and deposited as pseudofeces.

However, the aftershock area of the earthquake is not only in the Delarof segment but also in the Andreanof segment where the 1986 Andreanof earthquake occurred previously. We estimate the fault parameters of the 1996 earthquake by numerically computing the tsunami and comparing the waveforms with that recorded at Adak. The fault width is 30 km or less, and the average slip is about 4 m. The observed far-field tsunamis around the Pacific are also explained by the synthetic tsunami computed using the above fault parameters. The results indicate that the 1996 earthquake ruptured parts of both the Delarof and Andreanof segments. However, the 1996 earthquake did not rupture the region of the largest moment release by the 1986 earthquake. Copyright 1998 by the American Geophysical Union.

Removing the time-varying part of the field is a task of data reduction, and the most common time variation is the quiet daily variation, S (sub q) . It is thus valuable to have for reference type curves of the quiet daily variation in the total field. To meet this need, global data obtained during the 1965 International Year of the Quiet Sun have been used to derive type curves describing the S (sub q) variation of the total magnetic field, in addition to the traditional field components. As for the traditional components, the total-field curves show significant seasonal and latitudinal variability in amplitude and phase. The effect of the equatorial electro-jet is clearly evident. In both hemispheres of the globe there are bands of reduced amplitude in total-field signal between the equator and the path of the S (sub q) focus. These bands, here termed the total-field "doldrums", persist throughout the year. Copyright 1998 by the American Geophysical Union.

Synoptic measures of sediment contamination, toxicity, and macroinfaunal condition were made at 82 and 86 stations in 1994 and 1995, respectively, in accordance with a probabilistic sampling design. These data were used to estimate percentages of degraded vs. undegraded estuarine area from the perspective of sediment quality. Each year a sizable portion of the province (36% in 1994, 51% in 1995) showed some evidence of either degraded benthic assemblages, contaminated sediments in excess of bioeffect guidelines, or significant sediment toxicity (based on Ampelisca abdita and Microtox registered assays). However, co-occurrences of a degraded benthos and adverse exposure conditions (sediment contamination and/or toxicity) were much less extensive -- 17% of the province in 1994 and 25% in 1995. Each year only four sites, representing 5% of the province in 1994 and 8% in 1995, had degraded infauna accompanied by both sediment contamination and toxicity, suggesting that strong contaminant-induced effects on the benthos (based on such combined weight-of-evidence) were limited to a fairly small percentage of estuarine area province-wide. PCBs and pesticides (lindane, dieldrin, DDT and derivatives) were the most dominant contaminants over the two-year period. The broad-scale sampling design of EMAP was not intended to support detailed characterizations of potential pollutant impacts within individual estuaries. Thus, some estuaries classified as undegraded may include additional degraded portions outside the immediate vicinity of randomly sampled sites. Such localized impacts (not accounted for in the above estimates) were detected in this study at additional nonrandom supplemental sites near potential contaminant sources.

This involved, first, a petition from John Churchman for protection of an invention for determination of longitude using magnetic variation, and second, a request for congressional support for a voyage to Baffin's Bay to determine the cause of the magnetic variation. The discussions and arguments are an instructive introduction to those that arise when Congress considers scientific projects. The new government came into being after ratification by the requisite nine states. The new Congress met for the first time on March 4, 1789, in New York, but almost immediately adjourned in the absence of a quorum.

All species' identities determined by a combination of selective media, beta -hemolysis, and biochemical fermentation profiles were confirmed by PCR, with one exception. One strain (4-4), previously identified as L. innocua because of the lack of hemolysis on blood agar, was shown to be L. monocytogenes. In order to determine whether this isolate was a weakly hemolytic variant and thus potentially virulent, or whether it was truly unable to express listeriolysin (LLO), a number of phenotypic and genetic characterizations were performed. The strain was competent for expression of other L. monocytogenes virulence factors and characteristics such as the phosphatidylinositol-specific phospholipase C and the ability to adhere to and invade Caco-2 and J774 cells, but could not grow intracellularly and was avirulent in mice. DNA sequencing of the LLO gene (hly) from strain 4-4 showed that the genetic lesion was a single base-pair deletion, resulting in a frame-shift and subsequent stop codon in the translated open reading frame. Such a mutation is unique from those seen in previously described naturally occurring non-hemolytic L. monocytogenes strains.

Collection and recovery efficiencies were found to be essentially quantitative for C sub(2)-C sub(7) hydrocarbons and better than 95 and 93% for methanol and formaldehyde, respectively. CO sub(2) prevented the measurement of the C sub(2) hydrocarbons in atmospheric samples, and system response to ambient water vapor limited the precision of the measurement at very low C sub(y). The measurement system had an estimated uncertainty of 10% at ambient mixing ratios of 100 ppb C, and a detection limit of between 5 and 7 ppb C. C sub(y) was measured in Boulder, Colorado, during June of 1993 and at Chebogue Point, Nova Scotia, during the North Atlantic Regional Experiment intensive campaign, August to September 1993. C sub(y) values ranged from several hundred ppb C to 11 ppb C in Boulder, and from 177 to below 5 ppb C at Chebogue Point, with medians of 55 and 11 ppbC, respectively. C sub(y) was found to correlate with both CO and O sub(3) at higher levels of those two pollutants. The sum of C sub(y) and the C sub(2) hydrocarbons was virtually always equal to or greater than the sum of the hydrocarbons. Several exceptions to this occurred when high HC values were observed in cannister samples but not C sub(y) measurements. These instances were attributed to short-term perturbations from local sources. There was a net difference between total nonmethane organic carbon and the sum of hydrocarbons and carbonyls of 3.5 plus or minus 7.8 ppb C overall. This difference appears to be broadly correlated with anthropogenic pollution. There does not appear to be a significantly large reservoir of reactive carbon unaccounted for by hydrocarbon or carbonyl measurements. JF - Journal of Geophysical Research. D.

The correlation of alkyl nitrates (RONO sub(2)) with carbon monoxide makes it clear that the chemistry at this site is being driven by continental emissions, since RONO sub(2) compounds are known to be by-products of HC-NO sub(x) photochemistry. Comparison of the ratios of alkyl nitrates to their parent hydrocarbons to that of 2-butyl nitrate/butane showed significant deviations from trends predicted from rate constants, branching ratios, and loss rates. For ethyl nitrate this deviation is likely due to a combination of many additional pathways to the intermediate peroxy radical from the decomposition of larger alkoxy radicals. The propyl nitrates showed trends that differed from one another; 2-propyl nitrate was a factor of 2 to 3 higher than predicted, while 1-propyl nitrate was a factor of 8 to 10 higher than predicted. The trend of 3-pentyl nitrate/pentane was relatively close (about 50% lower) to the predicted trend. The relationship between PAN and PPN showed unexpectedly high ratios of PPN to PAN in air masses coming from the south and west of the site, implying a slight local source of PPN.

Under a 12 h light/12 h dark photoperiod, juveniles displayed a diurnal shoaling and activity pattern, characterized by fish swimming in cohesive groups during the day, with a cessation of shoaling and decreased swimming speeds at night. Prior studies of schooling fishes have demonstrated distinct light thresholds below which schooling abruptly ceases. To see if this threshold effect occurs in a predominantly shoaling species, like juvenile walleye pollock, another experiment was undertaken in which illumination was lowered by orders of magnitude, giving fish 20 min to adapt to each light intensity. Juvenile walleye pollock were not characterized by a distinct light threshold for shoaling; groups gradually dispersed as light levels decreased and gradually recoalesced as light levels increased. At light levels below 2.8 x 10 super(-6) mu E s super(-1) m super(-2), juvenile walleye pollock were so dispersed as to no longer constitute a shoal. Exposure to simulated predation risk had differing effects upon fish behavior under light and dark conditions. Brief exposure to a model predator in the dark caused fish to swim faster, for 5 or 6 min, than fish which had been similarly startled in the light. Chronic exposure to a living predator produced similar results; fish tended to swim slower when a predator was present in the light, but faster when a predator was present in the dark. In the light, shoaling and/or schooling provide protection against predators. But in the dark, with fish unable to see one another, increased prey activity resulting from predator disturbance may lead to accelerated dispersal of prey shoals. Thus, perceived predation risk may have different effects upon the spatial distribution of juvenile walleye pollock under light and dark conditions. This has implications for survival, as fish which have become widely scattered during the darkness may take longer to reform shoals at dawn, resulting in greater predation risk.

One hundred 1 d old glaucothoe were placed into each of 3 replicate 10 l aquaria, each containing a choice of 3 substrates: sand, gravel, or synthetic fiber mesh. Glaucothoe began settling on the first day, and <10% remained swimming after Day 6. Glaucothoe showed a significant preference for the structurally complex mesh substrate. Occupancy of mesh increased from 49% on Day 2 to 75% by metamorphosis to the first crab (C1) instar, with a mean of 62 plus or minus 11%, Glaucothoe rejected sand, and only 1% were observed on it. Settlement was also tested in aquaria with only sand, gravel or mesh substrates. Glaucothoe in gravel- or mesh-only aquaria settled rapidly, whereas 40% of glaucothoe in the sand-only aquarium continued swimming until metamorphosis to C1 instar. In addition, mean time-to-metamorphosis in the sand-only aquarium (17.6 d) was significantly greater than in other experimental aquaria (16.8 d). Glaucothoe in the sand-only aquarium exhibited marked diurnal swimming behavior; 66% were swimming at 14:00 h (vs a maximum of 12% in other aquaria), but only 5% (vs 1%) were swimming at 02:00 h. Daytime swimming probably allows glaucothoe to avoid nocturnal predators while searching for preferred substrates, i.e. those which are structurally complex, can be easily grasped, and provide a high degree of interstitial space.

The system was designed to interrogate previously PIT tagged juvenile salmonids migrating down the Columbia River without interfering with the traditional subsampling of fish passing through the facility. In addition, the design enables fish of virtually any size, and debris, to pass over the system's antennas without the port restrictions imposed by traditional pass-through PIT tag interrogation systems. We describe the fish facility in addition to the flat-plate system and its operation. The system tag reading efficiency was evaluated during 1996 and 1997 using a direct method based on the release of known numbers of tagged test fish and an indirect statistical procedure based on tagged run-at-large fish. The results showed that PIT tag reading efficiency during both years using the direct method averaged 97%, while that using the statistical procedure averaged 99% for the dual multiplexed antenna array. During the 1996 and 1997 field seasons 4371 and 14733 fish, respectively, were recorded. Daily system functionality was monitored using stick tests (i.e., the passing of PIT lagged sticks across the antenna array).

Project ACCESS (Accelerated Coastal Community Environmental Science Service) is a planned long-term, multi-agency ocean monitoring program that is designed to support the information needs of the infrastructure community. Near-real time data values will be collected, processed and delivered among the participants. The flow of data will be maintained as a dynamic process from a series of underwater sites and then distributed to the community. Project ACCESS is being constructed to maintain an ocean monitoring network which measures the fundamental parameters of ocean temperature, salinity, the velocity profile, turbidity, visibility, surface velocities and the wind field at each of the nodes of the network. A grid of nodes will be determined from the requirements of the infrastructure community that receives the data from the monitoring sites and executes the mission of the organization based in part on these values.

We tested the effects of site, planting density, water depth, and fertilizer addition on survival and growth through June 1996. Temperature, salinity, light transmittance, turbidity, and sediment properties at two restoration sites, Redfish Cove and Snake Island Cove, were similar to those in naturally occurring grassbeds in nearby Christmas Bay. Halodule survival, coverage, and new shoot densities were affected by site (significantly higher at Redfish Cove than at Snake Island Cove, which eventually failed), by planting density (significantly higher when planted on 0.25-m or 0.5-m centers rather than on 1.0-m centers), and by water depth (significantly higher when planted in relatively shallow water). Propagation (spreading from transplant units) was significantly greater from 0.25-m or 0.5-m center plantings but was not consistently affected by site or water depth. Fertilizer enhanced propagation but not survival. After two years, Redfish Cove produced belowground biomass similar to that observed in Christmas Bay, but aboveground biomass remained significantly less. Snake Island Cove plant mortality in September 1995 may have been presaged by low root-rhizome carbohydrate levels observed in October 1994, but causes remain unknown. Further restoration of Halodule to Glaveston Bay is possible at selected sites, but structural equivalency will take longer than two growing seasons to achieve.

A conspicuous pattern is alternating warm and cool periods of several years' duration. These variations in sea ice cover are reflected in the character of a subsurface cold pool, formed as stratification isolates the deeper cold waters from surface exchanges. The cold pool is better developed and more extensive in summers that follow deep southward penetration of winter sea ice. Interannual and decadal-scale variations in the distributions of some fish stocks reflect those of ice and thermal conditions. In particular, the distribution of walleye pollock, Theragra chalcogramma, varies significantly with multiannual cool and warm years while Arctic cod, Boreogadus saida, is only present within the cold pool. The relation among climate variations, sea ice cover, subsurface thermal conditions, and fish distribution provides information on how climate affects marine ecosystems and may also have practical application in predicting fish distributions.

Therefore, when I wrote the paper outlining the concept of evolutionarily significant units (ESUs) for identifying "distinct population segments" of Pacific salmon (Oncorhynchus spp.) under the U.S. Endangered Species Act (ESA), I realized that any attempt to identify conservation units below the species level would also generate a good deal of scientific discussion. This has proved to be the case. At the same time, a parallel discussion has taken place of which the primary focus is not biological issues but rather the degree to which the ESU concept satisfies the original intent of the U.S. Congress and the ESA itself. The recent essay in these pages by Pennock and Dimmick (1997) follows in this tradition. Pennock and Dimmick argue that the ESU concept adopted as policy by the National Marine Fisheries Service for identifying distinct population segments of Pacific salmon under the ESA (1) is inconsistent with the original intent of Congress, (2) unduly narrows the scope of populations that can be considered distinct under the ESA, and (3) limits flexibility under the ESA. The comments below address these criticisms as they apply to the NMFS ESU policy for salmon.

Marine reserves could potentially deal with many fishery problems that are not effectively addressed by other traditional management measures; they also offer numerous social, economic, and scientific benefits not directly related to fisheries. Limited but growing research has shown beneficial biological and economic effects of marine reserves on fisheries. More research is needed, especially at larger scales, to determine the ideal marine reserve size, number and location necessary to optimize fisheries productivity and resource conservation. Sufficient evidence is available to justify the expanded use of marine reserves in an adaptive approach to fisheries management.

AN - 16484200; 4365821 AB - 'Ecologic' reef fishes (basic research subjects) and 'Economic' reef fishes (exploited by humans) share fundamental early life-history attributes of small, widely dispersed planktonic eggs, larvae, and (for some species in both groups) pelagic juveniles. These attributes predispose the open populations of species in both groups to limitation resulting from environmentally induced fluctuations in recruitment from planktonic/pelagic to benthic stages. Rates of movement within and among reefs, one of several postrecruitment processes likely to be subject to density-dependent regulation, may differ between Ecologics (mostly small-bodied) and Economics (generally larger-bodied). This is because of differences between species in the two groups in size-related differences in the home ranges of individuals. Existing data, however, neither support the notion that natural growth and mortality rates basically differ between the adults of Ecological and Economic species, nor that the generally larger home ranges of larger-bodied adult Economics are more subject to density-dependent control. Further, the small-bodied young-of-year juveniles of both groups on average probably have similar growth and mortality rates and small individual home ranges that are equivalently affected by density dependence. In conclusion I argue that, because of fundamental similarities in the sizes and durations of planktonic propagules and spawning periodicities, certain Ecologics and Economics may comprise a single recruitment guild. Coefficients of growth and mortality for postsettlement Ecologics also may resemble, and be applied as preliminary proxies for, analogous coefficients for Economic species. The efficacy of management strategies such as harvest refugia may differ for Ecological and Economic species, however, depending on whether the refugia are used to counter growth or recruitment overfishing.

The simulated settling rates were greatly affected by the interaction between the hydrodynamics and the degree of spatial heterogeneity in the mortality fields. In the presence of an onshore Ekman drift, for example, settling rates tended to increase unless the mortality rate over the reef was much higher than elsewhere. Overall, the Simulations suggest that the meanders, eddies and gyres associated with the Florida current front can retain between 0.07 and 41% of the larvae with planktonic life spans on the order of 1 month. However, only a recirculating gyre enabled large numbers of larvae to settle within a few kilometers of their birth place. Assuming the mortality rate near the reef is 20-90% per day, but lower offshore, between 0.1 and 7% of the larvae retained are likely to settle. This implies that southeast Florida reef fish populations should be able to replenish themselves without relying on upstream sources of recruitment, provided they exhibit normal fecundities. The simulations also suggest that natural levels of variation in the mortality field or local currents can both cause large fluctuations in recruitment.

AN - 16338554; 6928 AB - PURPOSE: The shock testing of SEAWOLF-class submarine at alternative areas offshore of Mayport, Florida, and Norfolk, Virginia, is proposed. The SEAWOLF, a successor to the Los Angeles-class submarine, is an attack submarine that possesses reduced acoustic and electromagnetic signatures, higher top speed, greater maximum operating depth, greater ordnance capacity, and more advanced technology than any other submarine in the U.S. fleet. The first such submarine was completed in June 1995 and is expected to be delivered to the Navy in the summer of 1996. A new submarine cannot proceed beyond initial production until realistic survivability of the system has been thoroughly tested. This testing is commonly referred to as live fire test and evaluation, which involves creating a series of underwater detonations that propagate a shock wave through a ship's hull under deliberate and controlled circumstances. Shock tests simulate near misses from underwater explosions similar to those encountered in combat. Under the proposed action, the submarine would be subjected to a series of five 10,000-pound explosive charges of incrementally increasing intensity sometime between April 1 and September 30, 2000. At both the Mayport and Norfolk areas, possible test sites were first defined as any point along the 500-foot depth corridor within 100 nautical miles of a naval station and submarine repair facility. Environmental features near each area were mapped, including marine sanctuaries, artificial reefs, hard bottom areas, shipwrecks, ocean disposal sites, and critical habitat for endangered and threatened species. In addition to the two alternative test sites, a No Action Alternative is also under consideration; new activities affecting the physical environment would be conducted. The preferred alternative would shock test the SEAWOLF submarine offshore of Mayport, Florida, with mitigation to protect marine mammals and turtles. The Norfolk was not selected because it had a higher density of marine mammals. POSITIVE IMPACTS: The shock tests would enable the Navy to implement improvements to later ships of that class. NEGATIVE IMPACTS: The explosions would result in metal fragment deposits on the ocean floor, and possible death or injury to any pelagic fish or seabirds near the detonation point. The explosions would pose some risk to marine mammals and sea turtles in the area, at the very least causing them acoustic discomfort. Commercial and recreational fishing within ten nautical miles of the detonation point would be temporarily interrupted.

AN - 16342382; 6917 AB - PURPOSE: The reconstruction or modification of the new Maryland Route 331 (MD 331) bridge over the Choptank River, located on the Eastern Shore of Maryland, is proposed. The existing Dover Bridge, located six miles east of the city of Easton, would be replaced. The Dover Bridge is one of only three remaining single swing-span bridges in Maryland on the state system and the only remaining operating metal truss swiz-span bridge in Maryland eligible for inclusion in the National Register of Historic Places. The existing bridge has recently suffered mechanical malfunctions and operational problems and is deemed functionally obsolete due to its narrow road width. In addition to a No-Build Alternative, which would involve routine maintenance and spot improvements to the existing bridge, two build alternatives which would incorporate the existing bridge, and four new alignment alternatives which would involve the replacement of the bridge, are considered in this draft EIS. The Modification Alternative would involve the alteration of the curb and rail system of the existing bridge to provide additional roadway width and its upper diagonal architectural knees at the entrance portals of each of the three truss spans to increase roadway space for trucks and eliminate any perception of clearance constraints and, if structurally feasible, an installation of a detachable walkway outside the truss on one or both sides of the span to accommodate pedestrian and bicycle traffic. The Dual Bridge Alternative would provide a single-lane roadway on a fixed structure (32-foot deck width accommodating one 12-foot lane and two 10-foot shoulders) parallel to the existing bridge to accommodate westbound traffic. Each of the new alignment alternatives would feature a 50 mile-per-hour (mph) vertical design speed with maximum vertical grades of four percent, a typical section consisting of two 12-foot lanes and two eight-foot shoulders, and a 60-mph horizontal design speed. Two of the new alignment alternatives would be located north of the bridge and two south of the bridge. POSITIVE IMPACTS: The bridge design would accommodate vehicular, pedestrian, bicycle, and marine traffic while minimizing adverse impacts to environmental resources. NEGATIVE IMPACTS: The new alignment alternatives located to the south of the existing bridge would adversely affect one early colonial historic site. Shading, pier construction, and embankment placement would adversely affect as much as 4.7 acres of wetlands under the new alignment alternatives. Terrestrial resources could also be adversely affected, including agricultural fields and narrow pioneer edge forests. One tree, a 32-inch-diameter sycamore could be adversely affected. The dual bridge and new alignment alternatives would displace 1.8 to 3.0 acres of prime farmland and 0.2 to 1.9 acres of statewide important farmland.

To help fill this informational void, we conducted benthic invertebrate and sediment studies in a shallow navigation channel in the river before and after dredging. Benthic invertebrate and sediment samples were collected with a 0.1-m (super 2) Van Veen grab sampler at seven stations in the Wahkiakum County Ferry Channel. Washington (River Kilometer 70), and at an upstream reference area in 1993-1995. No significant effects (P>0.05) of the ferry channel dredging project on Corbicula fluminea. Ceratopogonidae larvae, Corophium spp., or total benthic invertebrate densities were detected in the statistical analysis, although benthic invertebrate densities were significantly different (P0.05) of the ferry channel dredging project on the benthic invertebrate community structure, as measured by H and E, were detected. No significant effects (P>0.05) of the ferry channel dredging project on sediment median grain size or percent volatile solids were detected. Results from this study will provide information to aquatic resource agencies that assess the potential environmental effects of dredging in similar habitats of the lower Columbia River.

A near-immediate field response and repeated plume mapping and sampling surveys during eight cruises over the next 3 years have provided a unique opportunity to estimate heat and mass fluxes from both event and chronic discharge during the life cycle of a newly created hydrothermal system. The intrusion triggered the release of at least three event plumes followed by chronic discharge focused at two sites: Flow, the site of a lava eruption at the distal end of the intrusion; and Floe, 30 km back along the trend of the dike. We have combined measurements of plume temperature anomalies, plume areal extent, and year-long averages of current flow at both sites to estimate the chronic hydrothermal heat flux H (sub u) . Initial values of H (sub u) at both sites were of order 10 (super 4) MW, declining over time t as H (sub u) = at (super -k ) , with k nearly equal 1. Significant plumes were no longer detectable at Flow by June 1995, or at Floe by June 1996. Elemental fluxes from the CoAxial system have been derived from H (sub u) and measurements of the ratios Mn/heat, Fe/heat, and particulate S/heat in chronic plumes. While Mn and Fe fluxes mirrored the power curve decline of heat, the combined regional particulate S (PS) flux experienced a second pronounced maximum some months after the eruption owing to a sharp increase in the S/heat ratio at Floc. Integrated inventories from chronic discharge were approximately 4 X 10 (super 17) J for heat, approximately 3 X 10 (super 8) mol for Mn, approximately 2 X 10 (super 8) mol for Fe, and approximately 1 X 10 (super 8) mol for PS. Realistic uncertainties for all species are roughly a factor of 2. The three event plumes accounted for <5% of the chronic plume inventories. Copyright 1998 by the American Geophysical Union.

The grabens are 10-100 m wide and 5-15 m deep and are located uprift and/or downrift of the eruptive vents that fed the flows. We interpret that these structures formed (or were reactivated) directly over the dike that fed the eruptions as it was intruding toward the surface. These graben structures are primary conduits for diffuse hydrothermal venting on the seafloor during the cooling of newly intruded dikes. The axial summit "graben" or "caldera" on the East Pacific Rise (EPR) in some locations has similar dimensions to the grabens observed on the JdFR, and we interpret that it too may be a dike-induced graben structure (although often buried by subsequent eruptions where it is narrowest). These grabens on the JdFR and the EPR are distinctly narrower and deeper than grabens that formed during well-documented dike intrusions on slow spreading rifts on land (Iceland and Afar). Mechanical modeling suggests that narrow grabens would form when a dike is at shallow depth where it imposes a high stress perturbation on the ambient stress state to cause faulting. Therefore the narrow grabens on the JdFR and EPR imply that a relatively high level of horizontal compressive stress typically exists perpendicular to the ridges, and this must be overcome by high dike-induced perturbations to cause faulting. This is probably because gradual plate spreading rarely gets enough time to lower the compressive stress significantly due to the high frequency of dike intrusion events relative to the plate spreading rate. The dikes that do intrude in this environment must have relatively high internal magma pressure. Therefore the size and character of dike-induced grabens that form at the surface on intermediate to fast spreading ridges reflect the fact that volcanism dominates over tectonism in regulating the local stress state where a robust magma supply is available.

The hydrographic section is composed of surveys obtained from 1990 to 1994. The potential temperature field shows pronounced downward sloping of the isotherms below 1.9 degrees (centered at about 150 m above the bottom) on either side of the ridge crest. The horizontal scale is about 2 km, comparable to the local Rossby deformation radius. The maximum potential temperature anomaly is greater than 0.03 degrees C. Significant light attenuation anomalies are also present. The mean along-ridge velocity section is constructed from the records of 85 current meters. The mean flow is southward at and to the east of the vent and northward to the west. Largest velocities occur at the depth of the neutrally buoyant plume. The cross-ridge shear is thus anti-cyclonic with a characteristic value of -0.05f. Geostrophic velocity fields obtained from the density section differ significantly from the field produced from the current meter data. An estimate of the net mean flux of anomalous heat gives 780 (+ or -400) MW to the south. Copyright 1998 by the American Geophysical Union.

Adults are exclusively intestinal parasites of vertebrates. This study includes those species found in vertebrates of marine and estuarine environments along the North American Atlantic coast between Maine and Texas. Species that can be found within that geographical range and those that typically infect freshwater fishes but that are occasionally present in marine or estuarine hosts are also included. The taxonamy, anatomy, natural history, and ecology of the phylum Acanthocephala are discussed, and an illustrated key to the genera is presented. Techniques, an annotated systematic treatment of all 43 species, and a systematic index are included. No systematic decisions will be made at this time, but areas where such decisions are pending will be indicated and discussed for future reports.

A discrimination function based on gonadosomatic indices was developed to classify maturation state of Atlantic salmon caught in Newfoundland and Labrador fisheries during the period 1985-1988. Atlantic salmon believed to be on feeding migrations were found to be in advanced states of sexual development. In an attempt to clarify the meaning of these data, chronological transects of Sr:Ca ratios from the otoliths of maturing and immature one-seawinter fish were collected. Sr:Ca ratios deposited during freshwater residency varied by stock and appeared to reflect the environmental availability of Sr. Sr:Ca ratios deposited during marine residency appeared to reflect somatic growth and sexual development. We detected no differences in the postsmolt Sr:Ca ratios for mature and immature Atlantic salmon from a hatchery stock originating in North America, suggesting that for this stock, little differentiation occurs between the maturity components. Mechanisms by which environment may contribute to the variation in maturation rate of North American Atlantic salmon are discussed.

Despite the widespread use of echosounders, few guidelines aid in the choice of appropriate sonar system parameters for acoustic surveys. Choice of acoustic carrier frequency is analogous to the choice of spotlight colour used to illuminate a painting. Three primary biological factors influence the scattering of sound by aquatic organisms: swimbladder presence, organism length, and organism behaviour. We illustrate the influence of these factors on the amplitude of backscattered echoes using a Kirchhoff-ray mode scattering model to quantify fish and zooplankton backscatter as a function of carrier frequency, fish length, and swimbladder aspect. Model results illustrate that echo amplitudes from aquatic organisms are largely dependent on the presence or absence of a swimbladder. Target strengths generally increase with increasing carrier frequency and organism length. Swimbladder angle relative to the incident sound wave affects scattering amplitudes at all frequencies. Measurements of backscatter from swimbladdered fish are relatively robust when the ratio of fish length to acoustic frequency wavelength ranges between 2 and 10. As fish length to frequency wavelength ratios increase, echo amplitudes become more dependent on aspect and peak when the swimbladder is perpendicular to the acoustic wavefront.

Midway Islands (Fig. 1) is the site of the most depleted monk seal population. Because of continuing Navy operations at Midway in the early 1980s, it was not practical to include Sand Island at Midway in the designation of critical habitat for the species. For the same reason the HMSRT did not recommend specific recovery efforts at Midway in the Recovery Plan. With the recent closure of the Midway Naval Air Facility, establishment of the Midway Atoll National Wildlife Refuge (Refuge), and transfer of the atoll to the U.S. Fish and Wildlife Service (USFWS) in June 1997, planning to recover this endangered seal population must now begin. On December 5-6, 1995, the Honolulu Laboratory of the National Marine Fisheries Service (NMFS), conducted a workshop to develop recommendations to facilitate recovery of the monk seal population at Midway. Workshop participants were presented background data on the Midway monk seal population, results of the 1992 monk seal rehabilitation and translocation to Midway, population trend data for certain Midway reef fishes, and results of the Kure Atoll monk seal recovery efforts during 1985-91 and 1993-95. The USFWS management strategy for the Refuge was also presented. The recommendations of this workshop were the basis for developing recovery actions presented in this document.

One thousand and thirteen fur seals (565 males and 448 females) were measured in a longitudinal study and an additional 2697 animals were measured at birth. At birth, female pups were about 10% lighter and about 3% shorter than male pups. The coefficients of variation of mass (12.5 and 12.8%) and length (4.5 and 4.7%) were similar for the two sexes. We partitioned the lactation period into four time periods: 1, the perinatal period (ages 0-10 days); 2, the early development period (ages 11-40 days); 3, the period of intensive molting (ages 41-80 days); and 4, the preweaning period (ages 81-140 days).

ER - TY - JOUR T1 - Foraging modes of chinstrap penguins: contrasts between day and night AN - 17095175; 4392913 AB - Penguins rely on vision to travel and hunt at sea. Vision in marine predators, particularly those hunting phototactic prey under a broad range of light intensities, must be better understood to realize how these species respond to changes in their environment. We studied the effects of daily cycles in light intensity on visual predators by examining the duration and timing of chinstrap penguins' Pygoscelis antarctica foraging trips and the size, composition, and timing of their meals. We used radio telemetry and stomach-contents sampling to study adult penguins that were provisioning chicks during the summers of 1993 and 1994 at Seal Island, Antarctica. The penguins rarely initiated or terminated foraging trips at night, but otherwise varied the timing and duration of trips to sea. Cluster analyses using departure and arrival times revealed 5 distinct modes of foraging: 3 were strictly diurnal (early, mid-, and late) and 2 were partly nocturnal (overnight and extended). Durations of diurnal trips (4 to 11 h) were shorter than overnight (13 to 14 h) and extended trips (18 to 22 h). Early and mid-diurnal trips and extended trips were significantly shorter in 1993 than in 1994; late diurnal and overnight trip durations did not differ between years. Diurnal foraging was most common in 1993, whereas overnight foraging predominated in 1994. Shortened diurnal foraging in 1993 appears to have increased the frequency of diurnal foraging by allowing more parent birds to alternate diurnal trips within a single day and by reducing the incidence of birds extending diurnal foraging through the night. That penguins foraged more frequently by day when permitted by shorter trip durations (in 1993) suggests that they opted to forage diurnally whenever possible. Returning diurnal and overnight foragers had greater than 99 and 74% Antarctic krill Euphausia superba by weight in their stomachs, respectively. However, overnight foragers also returned with significant amounts of highly digested remains of pelagic fish, suggesting birds were in offshore waters taking fish during the night. In contrast, only 1 out of 40 diurnal foragers from both years combined had evidence of fish. Thus, the daily light cycle affected both the timing and duration of chinstrap penguin foraging as well as the type of prey consumed during trips to sea.

There were five intense (or major) Saffir-Simpson category 3, 4, or 5 hurricanes (average is 2.3 intense hurricanes) with 11.75 intense hurricane days (average is 4.7). The net tropical cyclone activity, based upon the combined values of named storms, hurricanes, intense hurricanes, and their days present, was 229% of the average. Additionally, 1995 saw the return of hurricane activity to the deep tropical latitudes: seven hurricanes developed south of 25 degree N (excluding all of the Gulf of Mexico) compared with just one during all of 1991-94. Interestingly, all seven storms that formed south of 20 degree N in August and September recurved to the northeast without making landfall in the United States. The sharply increased hurricane activity during 1995 is attributed to the juxtaposition of virtually all of the large-scale features over the tropical North Atlantic that favor tropical cyclogenesis and development. These include extremely low vertical wind shear, below-normal sea level pressure, abnormally warm ocean waters, higher than average amounts of total precipitable water, and a strong west phase of the stratospheric quasi-biennial oscillation. These various environmental factors were in strong contrast to those of the very unfavorable conditions that accompanied the extremely quiet 1994 hurricane season. The favorable conditions for the 1995 hurricane season began to develop as far back as late in the previous winter. Their onset well ahead of the start of the hurricane season indicates that they are a cause of the increased hurricane activity, and not an effect. The extreme duration of the atmospheric circulation anomalies over the tropical North Atlantic is partly attributed to a transition in the equatorial Pacific from warm episode conditions (El Nino) to cold episode conditions (La Nina) prior to the onset of the hurricane season. Though the season as a whole was extremely active, 1995's Atlantic tropical cyclogenesis showed a strong intraseasonal variability with above-normal storm frequency during August and October and below normal for September. This variability is likely attributed to changes in the upper-tropospheric circulation across the tropical North Atlantic, which resulted in a return to near-normal vertical shear during September. Another contributing factor to the reduction in tropical cyclogenesis during September may have been a temporary return to near-normal SSTs across the tropical and subtropical North Atlantic, caused by the enhanced tropical cyclone activity during August. Seasonal hurricane forecasts for 1995 issued at Colorado State University on 30 November 1994, 5 June 1995, and 4 August 1995 correctly anticipated an above-average season, but underforecast the extent of the extreme hurricane activity.

The sensitivity of the new parameters was tested by individual parameter perturbation (IPP) analysis. The model was applied to estimate individual and total cohort food consumption of age-0 pollock in two areas of high pollock density in the Gulf of Alaska during the summer of 1990. Total cohort consumption was compared with zooplankton biomass and production estimates for the same areas and times of the year. The model was also used to examine the bioenergetic implications of age-0 pollock diel vertical migration through a thermal gradient. During a 1-month bioenergetics simulation, individual daily consumption decreased from 16 times 0% to 6 times 0% of wet body weight. Daily ration estimates corresponded well with independent field estimates of daily ration for the same areas and time of the year. Comparison of total cohort consumption with prey availability (production and biomass) indicated minimal potential for food limitation. Bioenergetic optimization of growth can be a potential benefit of diel vertical migration to age-0 pollock, however more information on prey density and distribution is needed to test this hypothesis thoroughly.

Toxaphene was the dominant organochlorine contaminant in the Lake Superior food web, with concentrations 2-15 times higher than total PCBs. Among the biota studied, wet weight toxaphene levels were highest in bloaters (Coregonus hoyi) at 1100 plus or minus 270 ng/g (mean plus or minus 1 standard deviation) and lowest in Mysis relicta (32 plus or minus 804 ng/g). Total PCB concentrations ranged more than a factor of 20 on a wet weight basis but less than a factor of 6 on a lipid weight basis. The lipid content of the organisms explains 81% of the variability in wet weight t-PCB, with trophic position exerting a smaller influence. Using path analysis and regression techniques, the main influence of trophic position on t-PCBs was shown to be due to the concurrent increase in lipid content with trophic position. The relative distributions of organochlorines among trophic levels were very similar, despite the 3 orders of magnitude range in OC hydrophobicity. Unlike our work in Lake Baikal, the accumulation of OCs in the Lake Superior food web was not significantly (p < 0.05) related to the log octanol/water (K sub(ow)) partition coefficient, suggesting either that organochlorines in this food web equilibrate with surrounding dissolved OCs rapidly relative to dietary uptake or that the OC assimilation efficiency of predators does not vary with log K sub(ow).

The navy initially contracted Hughes Aircraft Company to develop a rainfall-retrieval algorithm prior to the launch of SSM/I. This first-generation operational navy rainfall retrieval algorithm, referred to as the D-Matrix algorithm, was used until the development of the second-generation algorithm by the SSM/I Calibration/Validation team, which has subsequently been replaced by a third-generation algorithm developed by the National Oceanic and Atmospheric Administration/National Environmental Satellite, Data and Information System. Results from both the D-Matrix and Cal/Val algorithms have been included in a total of five algorithm intercomparison projects conducted through the Global Precipitation Climatology Project and WetNet. A comprehensive summary of both quantitative and qualitative results from these intercomparisons is given detailing many of the strengths and weaknesses of the algorithms. Based on these results, the D-Matrix algorithm was found to produce excessively large estimates over land and to poorly represent the spatial structure of rainfall systems, especially at higher latitudes. The Cal/Val algorithm produces more realistic structure within storm systems but appears to overestimate the region of precipitation for many systems and significantly underestimates regions of intense rainfall. While the Cal/Val algorithm appears to provide better instantaneous rainfall estimates in the Tropics, the D-Matrix algorithm provides reasonable time-averaged results for monthly or longer periods.

This is accomplished through use of a new technique, biohydro-optical classification, that applies a rudimentary submarine light budget incorporating climatologies of incident light, mixed-layer thickness, and chlorophyll to recognize fundamental modes of tropical plankton ecosystems. The 3 types of biohydro-optical classes found in the Arabian Sea, Typical Tropical, Mixed-Layer Bloom, and Transitional, are shown to evolve through the spring intermonsoon (March through May), summer southwest monsoon (June through August), and fall intermonsoon (September through November) under climatic forcing and in response to the resulting biological variability. Virtually all of the open Arabian Sea is within the Typical Tropical Class at the close of the spring intermonsoon. This class type is intended to identify the epipelagic plankton ecosystem mode associated with tropical regions containing a deep chlorophyll maximum (DCM) maintained by active algal growth, and a light-rich, oligotrophic shallow zone containing a phytoplankton association which depends largely upon regenerated nutrients. At the close of the southwest monsoon in August, a Mixed-Layer Bloom Province covers much of the northern Arabian Sea. This province class corresponds to the ecosystem mode represented by tropical regions undergoing marginal or mid-ocean upwelling and greatly simplifies regional extrapolation of the local primary production algorithm. At the onset of the fall intermonsoon, the Mixed-Layer Bloom Province in the northern and western Arabian Sea is superseded by a Transitional Province, which persists through the fall intermonsoon. We interpret the upper layer of the fall intermonsoon Transitional Province in the Arabian Sea as a special case of the shallow regenerative plankton ecosystem of oligotrophic ocean areas, where rates of zooplankton-driven nutrient regeneration and recycled production, key processes in the upper layer of the classic 2-layer euphotic zone of oligotrophic low-latitude oceans, reach extreme values.

This objective was addressed in two separate phases. In the first study, concentrations of AHs and PCBs were measured in individual fish from four sites in Puget Sound, Washington (Eagle Harbor, Sinclair Inlet, Yukon Harbor, and Pilot Point) with different levels of AH and PCB contamination in sediments and their ovarian development was monitored during the 1989-1991 spawning seasons. In these fish, egg weight was negatively correlated with levels of PCBs in the liver. However, contaminant exposure levels were not significantly associated with the probability of entering vitellogenesis or with gonadosomatic index, plasma estradiol concentrations, or fecundity. In the second study, gravid female soles were taken from Eagle Harbor, Sinclair Inlet, Yukon Harbor, and University Point (known spawning areas for rock soles), and hormonally induced to spawn in the laboratory. Eggs were fertilized with pooled sperm from reference males. Consistent with the first study's findings, fish from Sinclair Inlet, where sediments contain elevated concentrations of PCBs, produced eggs with significantly reduced weight. Furthermore, the overall spawning success of fish from the site with the highest level of AH contamination (Eagle Harbor) was significantly impaired. These findings suggest that environmental exposure to AHs and PCBs may reduce reproductive success in female rock soles, but this species appears to be more resistant to such effects than other Puget Sound flatfish species, such as the English sole Pleuronectes vetulus.

Immunosuppressed fish may be more susceptible to disease and ultimately experience an increase in mortality. To evaluate this possibility, differences in susceptibility to a marine pathogen in outmigrating juvenile chinook salmon from an urban estuary and a nonurban estuary in Puget Sound were assessed. Juvenile chinook salmon were sampled from hatcheries before their release and subsequently from their respective estuaries as the population outmigrated from freshwater to the saltwater environment during the springs of 1993 and 1994. The study was repeated during a 3-month period to assess the duration of the effect after the fish were removed from the source of contaminants and was replicated during a 2-year period to examine interannual variation. Bile, liver, and stomach contents were collected from fish after capture to determine exposure to organic chemical pollutants. Examination of these tissues demonstrated that juvenile salmon from the urban estuary were exposed to higher concentrations of polycyclic aromatic hydrocarbons and polychlorinated biphenyls than juveniles from the nonurban estuary or hatcheries. Juvenile salmon were challenged with serial doses of a marine pathogen, Vibrio anguillarum (serotype 1575), and mortality was measured daily for 7 d. In both years. salmon from the urban estuary challenged with V. anguillarum exhibited a higher cumulative mortality after exposure to the pathogen than salmon from the hatcheries or the nonurban estuary. Our results together with our previous findings support the hypothesis that contaminant-associated immunodysfunction in juvenile chinook salmon may lead to increased susceptibility to infection by a virulent marine bacterium.

The assessment of the model was based on changes to the deep convection and planetary boundary layer parameterizations to determine their impact on some of the model deficiencies identified during previous hurricane seasons. Some of the deficiencies in the hurricane forecasts included a weakening of the storm circulation with time that seriously degraded the track forecasts. In the larger-scale forecasts, an upper-level easterly wind bias was identified in association with the failure of the model to maintain the midoceanic upper-tropical upper-tropospheric trough. An overall modest improvement is shown in the large-scale upper-level tropical winds from root-mean-square-error calculations. Within a diagnostic framework, an improved simulation of the midoceanic tropical trough has contributed to a better forecast of the upper-level westerly flow. In the hurricane forecasts, enhanced diabatic heating in the model vortex has significantly improved the vertical structure of the forecast storm. This is shown to contribute to a substantial improvement in the track forecasts.

At landfall, Luis and Marilyn contained maximum sustained winds (marine exposure) estimated at near 60 and 46 m s super(-1), respectively. The strongest landfalling storm of the 1995 season, Luis, decreased in intensity from a category 4 to 3 on the Saffir-Simpson scale shortly before the eyewall crossed the Islands of Antigua, Barbuda, St. Kitts-Nevis, St. Barthelemy, St. Martin, and Anguilla. Hurricane Marilyn strengthened as it approached the U.S. Virgin Islands, with St. Thomas bearing the brunt of the north and south eyewall winds of 46 m s super(-1) (marine exposure) and St. Croix being affected by the relatively weak western eyewall peak winds of 35-40 m s super(-1) (marine exposure). For Luis and Marilyn only surface winds with marine exposures were analyzed because of unknown small-scale interactions associated with complex island terrain with 500-1000-m elevations. Wind engineering studies suggest that wind acceleration over blunt ridges can increase or "speed up" winds by 20%-80%. Topographic effects were evident in damage debris analyses and suggest that an operational method of assessing terrain-induced wind gusts (such as a scaled down mesoscale model) is needed. After landfall as a marginal hurricane over central Florida, Hurricane Erin regained strength over the Gulf of Mexico with a well-defined radar reflectivity structure. Erin struck the Florida panhandle near Navarre Beach with maximum sustained surface winds of 35-40 m s super(-1) affecting the Destin-Ft. Walton area. Hurricane Opal made landfall in nearly the identical area as Erin, with maximum sustained surface winds of 40-45 m s super(-1), having weakened from an intensity of nearly 60 m s super(-1) only 10 h earlier. Opal was characterized by an asymmetric structure that was likely related to cold front interaction and an associated midlevel southwesterly jet. Roxanne struck Cozumel, Mexico, with sustained surface winds (marine exposure) of 46 s super(-1), crossed the Yucatan, and meandered in the southwest Gulf of Mexico for several days. While in the Bay of Campeche, Roxanne's large area of hurricane-force winds disabled a vessel, which lead to the drowning deaths of five oil industry workers. High-resolution wind records are critical to preserving an accurate extreme wind climatology required for assessment of realistic building code risks. Unfortunately, power interruptions to Automated Surface Observing Stations on the U.S. Virgin Islands (St. Croix, St. Thomas) and Destin, Florida, prevented complete wind records of the eyewall passages of Marilyn and Opal, respectively.

The Fv is composed of the polypeptide chains of the V sub(H) and V sub(L) domains expressed independently and isolated as inclusion bodies. The Fv is prepared by combining and refolding equimolar amounts of guanidine chloride solubilized inclusion bodies. The Fv is stabilized by an engineered interchain disulfide bridge between residues V sub(L)100 and V sub(H)44. This construct has a similar binding affinity as that of the single-chain construct (Benhar and Pastan, Clin. Cancer Res. 1:1023-1029, 1995). The B1 disulfide-stabilized Fv (B1dsFv) crystallizes in space group P6 sub(1)22 with the unit cell parameters a = b = 80.1 angstrom, and c = 138.1 angstrom. The crystal structure of the B1dsFv has been determined at 2.1-angstrom resolution using the molecular replacement technique. The final structure has a crystallographic R-value of 0.187 with a root mean square deviation in bond distance of 0.014 angstrom and in bond angle of 2.74 degree . Comparisons of the B1dsFv structure with known structures of Fv regions of other immunoglobulin fragments shows closely related secondary and tertiary structures. The antigen combining site of B1dsFv is a deep depression 10-angstrom wide and 17-angstrom long with the walls of the depression composed of residues, many of which are tyrosines, from complementarity determining regions L1, L3, H1, H2, and H3. Model building studies indicate that the Lewis super(Y) tetrasaccharide, Fuc-Gal-Nag-Fuc, can be accommodated in the antigen combining site in a manner consistent with the epitope predicted in earlier biochemical studies (Pastan, Lovelace, Gallo, Rutherford, Magnani, and Willingham, Cancer Res. 51:3781-3787, 1991). Thus, the engineered disulfide bridge appears to cause little, if any, distortion in the Fv structure, making it an effective substitute for the B1 Fab.

Under the auspices of the National Oceanic and Atmospheric Administration's National Status and Trends Program, the National Benthic Surveillance Project accumulated a database of synoptic sediment contaminant concentrations and indices of biological effects that were measured in indigenous animals collected during field surveys conducted from 1984 to 1994. This compilation of data provided the opportunity to develop a new approach for determining sediment quality criteria to add to the current repertoire of environmental assessment tools. Using a two-segment hockey stick regression, statistically significant chemical thresholds of biological effects were estimated for hepatic lesion prevalences in English sole (Pleuronectes vetulus, formerly Parophrys vetulus) in relation to sediment concentrations of polycyclic aromatic hydrocarbons. These threshold estimates are notably lower than many of those reported for other techniques. Application of this relatively simple dose-response model to subacute, chronic effects that are involved in hepatocarcinogenesis and associated with sediment toxicant content (1) reflects the link between toxicopathic disease progression and conditions observed in benthic fish exposed to contaminants and (2) provides endpoints for assessing sediment quality contaminant concentrations that are not necessarily acutely fatal but may have long-term health implications for populations that are chronically exposed.

Migratory and endemic species of whales, seals and birds benefit from the high biomass of their principal prey, krill (Euphausia superba) and cephalopods, in this area. Most species of baleen whales and male sperm (Physeter macrocephalus) whales in the Southern Hemisphere migrate between low-latitude breeding grounds in winter and highly productive Antarctic feeding grounds in summer. Here I show the importance of the southernmost reaches of the strongest ocean current, the Antarctic Circumpolar Current (ACC), to a complex and predictable food web of the Southern Ocean. The circumpolar distributions of blue (Balaenoptera musculus), fin (Balaenoptera physalus) and humpback (Megaptera novaeangliae) whales from spring to midsummer trace the non-uniform high-latitude penetration of shoaled, nutrient-rich Upper Circumpolar Deep Water, which is carried eastward by the ACC. The poleward extent of this water mass delineates the Southern Boundary of the ACC and corresponds not only to the circumpolar distributions of baleen whales, but also to distributions of krill and to regions of high, seasonally averaged, phytoplankton biomass. Sperm whales, which feed on cephalopods, also congregate in highest densities near the Southern Boundary. The association of primary production, Krill, and whales with the Southern Boundary, suggests that it provides predictably productive foraging for many species, and is of critical importance to the function of the Southern Ocean ecosystem.

Salinity in the plumes was depressed 1-2 parts per thousand compared to surrounding shelf waters. One plume was at least 160 km long, 20 km wide, and 5-7 m deep. The other was 75 km long, 25 km wide and 5-7 m deep. Both plumes disintegrated almost completely in 6 days due to mixing or advection away from the sampling area. Measurement and analysis of short-lived Ra isotopes and Si indicated that the plumes were not caused by river discharge but were rather due to an intense rain event a few days prior to the sampling cruise. With only salinity measurements we would have incorrectly concluded that the freshened water was a result of river plumes having entered the shelf. The rain was associated with the system that spawned tropical storm Alberto. We estimate that 220-330 mm of rain fell on the coastal ocean immediately before the cruise. Accompanying the rain were pesticides and nutrients. We estimate that the flux of nitrate from the rain was twice the riverine flux of nitrate to the study area in the month preceding the cruise.

N1 - Last updated - 2014-05-06 ER - TY - JOUR T1 - Oxygen isotopic equilibrium between carbon dioxide and water in soils AN - 17170277; 4472280 AB - Exact mathematical solutions are presented for some simple cases of isotopic equilibration of oxygen-18 between carbon dioxide and water in soils, which is a major component of the super(18)O isotopic balance of atmospheric CO sub(2). The soil-to-air exchange is made up of 2 components. First, respiratory CO sub(2) is produced in the soil and escapes to the atmosphere through diffusion. The lighter isotopic species escapes a little more rapidly, enriching the heavier isotopic species in the CO sub(2) left behind in the soil, which is then out of isotopic equilibrium with soil water. Therefore, simultaneously with the escape of gas, there is continuous re-equilibration of CO sub(2) with soil water. The second component of soil-to-air exchange is independent of the production of CO sub(2) in the soil: the invasion of atmospheric CO sub(2) into the soil, where it equilibrates isotopically with the soil moisture before diffusing back out. A consequence for atmospheric isotopic measurements is that, in general, for respired CO sub(2) a plot of the isotopic ratio versus the inverse of the concentration is curved, and that the slope in the vicinity of the ambient concentration may not point towards the isotopic ratio of the net CO sub(2) evolved from the soil.

Fish avoided fresh tailings in favour of natural marine sediment (control) and weathered tailings (75 years old). Only when fresh tailings were covered with 2 cm of control sediment did fish prefer control and fresh tailings equally. Survival of fish was similar (p = 0.66) for fish held on all test sediments. Fish held on fresh tailings for 60 d grew significantly (p = 0.013) less than control fish during the first, but not the second, month. Avoidance or short-term reductions in flatfish growth may occur from submarine disposal of tailings. Rapid burial of tailings in areas with high natural sedimentation (e.g., large river mouths) may accelerate recovery of the sea floor.

The Great Lakes Environmental Research Laboratory used their conceptual models for simulating moisture storages in, and runoff from, the 121 watersheds draining into the Great Lakes, over-lake precipitation into each lake, and the heat storages in, and evaporation from, each lake. This transposition of actual climates incorporates natural changes in variability and timing within the existing climate; this is not true for General Circulation Model-generated corrections applied to existing historical data in many other impact studies. The transposed climates lead to higher and more variable over-land evapotranspiration and lower soil moisture and runoff with earlier runoff peaks since the snow pack is reduced up to 100%. Water temperatures increase and peak earlier. Heat resident in the deep lakes increases throughout the year. Buoyancy-driven water column turnover frequency drops and lake evaporation increases and spreads more throughout the annual cycle. The response of runoff to temperature and precipitation changes is coherent among the lakes and varies quasi-linearly over a wide range of temperature changes, some well beyond the range of current GCM predictions for doubled CO sub(2) conditions.

Habitat affinities were quantitatively defined using consistently collected data with a 16-m high-rise otter trawl at 314 Virginian Province (US) sites from 1990 to 1993. Catch rates and field-recorded salinity, depth, sea bed type, and geography (coastal system) associated with each trawl were analysed. Habitat affinity was quantified by comparing the concentration of fish in a particular habitat with the prevalence of that habitat. Fishes exhibited a specific habitat affinity even though they occurred across a range of environmental gradients. Fish were most associated with salinity (14 of 19 species/life-stage groups had a significant affinity for at least one salinity zone). Three-quarters of the flatfish displayed an affinity for a selected sea bed type; the same percentage of sciaenids had an affinity for a particular salinity zone.

These additives reduce the flammability of a wide variety of common polymers such as polypropylene, nylon, polymethylmethacrylate, poly(vinyl alcohol), and cellulose. In an effort to determine how these additives reduce polymer flammability, we have used electron paramagnetic resonance spectroscopy and solid-state super(13)C and super(29)Si nuclear magnetic resonance spectroscopy to characterize the combustion chars or residues. These data indicate that, in the case of poly(vinyl alcohol), the additives do not change the type of char formed, but they do change the rate of char formation relative to the rate of fuel generation. We also found that, using only CP/MAS super(13)C NMR, there can be significant intensity distortions which complicate interpretation, if the char is hydrogen depleted and contains paramagnetic centres.

Although previous genetic surveys have revealed considerable genetic differences among populations with different life history types and from different major river drainages, it is not clear to what degree these genetically distinct populations are connected by low levels of gene flow. The work described in this paper addresses this question by surveying DNA restriction site variation at six nuclear genes from nine populations encompassing most of the species's North American range, and then attempting to fit the patterns of variation observed at these genes to five different evolutionary models using computer simulations of the coalescent process. Two commonly used constant population size models, one hypothesizing no migration among populations and one hypothesizing equal rates of migration among populations, were found to be statistically inconsistent with the observed patterns of variation. The other three models, which involved either recent divergence among populations coupled with large changes in populations size, unequal migration rates among populations, or selection, were all found to be consistent with the observed patterns of variation. Assuming selective neutrality, these results suggest that either the populations have all descended from a common ancestral population within the last similar to 50,000 years and have all suffered large declines in effective population size since that time, or that they have a more ancient divergence time but are connected by low levels of gene flow. These conclusions rest on the assumption of selective neutrality. With the methods employed, it was not possible to simultaneously test hypotheses of both selective neutrality and population structure.

I find also that there is no correspondence between geographic and genetic distances separating subpopulations, an increasingly common result in spatially stratified studies of genetic structure in marine invertebrates. F-statistics, calculated for two years from electrophoretic variation at five polymorphic allozyme loci, indicate significant genetic differentiation among sampling quadrats within each of two bays ( theta = 0.064-0.208), between tide zones within a bay ( theta = 0.025-0.157) and between bays ( theta = 0.079). Spatial autocorrelation analysis was used to explore genetic differentiation at smaller spatial scales; estimated patch sizes (within which genetic individuals are randomly associated) indicated no appeciable genetic structure at scales less than 20 m X 20 m. Calculated values of F-statistics were a function of the spatial scale from which samples were drawn: increasing the size of the "subpopulation" included in calculation of fixation indices for the same "total" sample resulted in an increase in the magnitude of f (e.g., from 0.092 to 0.181) and a decrease in theta (e.g., from 0.186 to 0.025). On the basis of the best estimate of the spatial scale of subpopulations, the effective number of migrants per generation (N sub(e)m) ranges from 1.1 to 2.8. Genetic consequences of the disturbance regime in the eelgrass habitat sampled were extreme variation between years in the allele richness and proportion of heterozygotes in a sample and a positive relationship between the extinction probability of patches and the genetic variance among them. The changes in F-statistics as a function of sampling scale and the observation that theta among sampled quadrats was positively associated with the probability of extinction among quadrats indicated that indirect estimates of gene flow (N sub(e)m) calculated from theta should be cautiously interpreted in populations that may not yet be in drift-migration equilibrium.

Its polymorphic nature and maternal inheritance are characteristics that have, combined with its sequence information, enabled investigators to identify missing persons, war casualties and individuals involved in mass disasters and criminal cases. Various screening procedures have been developed to reduce the need to sequence samples that do not match, but DNA-sequence information is still necessary to verify a match. Even though several challenges remain before mitochondrial-DNA-sequence information can be used unambiguously, comparative mitochondrial-DNA-sequence analysis appears to be a reliable and powerful means for human identification.

Associated prey assemblages were sampled with neuston and plankton nets in 1984. Salmon diets included at least 30 taxa of prey. Crustaceans (principally hyperiid amphipods), fish, and tunicates were the most important prey of pink (O. gorbuscha), chum (O. keta), and sockeye (O. nerka) salmon. Fish were the most important prey of coho (O. kisutch) and chinook (O. tshawytscha) salmon and made up the highest percentage of stomach content weight for all salmon species. Diet shifted from crustaceans in 1983 to fish in 1984 for juvenile pink, sockeye, and chum salmon. Diet overlapped significantly (C sub( lambda )>0.60) between pink and sockeye salmon, pink and chum salmon, and chum and sockeye salmon. Coho salmon diet overlap was <0.60 in all paired comparisons. Nearly all (98.6%) of the 2,210 stomachs examined were at least half full. Although, in general, prey consumed were not very similar to prey observed in the environment, the composition of salmon diets was more similar to neuston collections than to zooplankton collections.

These data were processed to give profiles of volume scattering strength. A deep scattering layer dominated the time-depth patterns of backscatter. This layer migrated from a depth of 300-400 m during the day to 0-100 m at night, when it was located just above the thermocline. The source of backscatter was primarily small fish and squid, which are dolphin prey. Dolphin sighting rates were correlated positively with nighttime volume scattering strength above the thermocline. Spatial and temporal variability of prey biomass in the surface layer, as indexed by volume scattering strength, may have important consequences for dolphin feeding, as well as for distributional responses to habitat variability by dolphins.

Although field collections have suggested that juveniles are obligate residents of the neuston, laboratory experiments on diel movements indicated the potential for downward movement during the day, when activity levels were high and active foraging would be likely. The relationship of downward movement to fish size (small vs. large juveniles), prior feeding success (high vs. low rations) and thermal structure of the water column (isothermal vs. varying intensities of thermal stratification) were tested. Thermal stratification inhibited downward movement, with sablefish displaying clear avoidance of cold water even when the thermal gradient was moderate (12 degree C top layer and 8 degree C bottom layer). However, sablefish could be induced to swim downward into cold water if food was introduced beneath the thermocline. Across all temperature treatments, occurrence in cold water significantly increased when food was present. Increasing the sharpness of the thermal gradient (top layer = 12 degree C, bottom layer = 8, 6, 4 or 2 degree C) did not affect the percentage of time spent in cold water, but did shorten the maximum time an individual would spend beneath the thermocline. Movement into cold water constituted a potentially lethal risk for juvenile sablefish; dives beneath the thermocline that exceeded 60 s resulted in loss of equilibrium and immediate death for small fish moving from 12 to 2 degree C water. Thus, sablefish displayed behavioral trade-offs between food acquisition and the physiological risk of cold temperatures, similar to previous studies documenting balancing of foraging behavior and predation risk. Behavioral responses to thermal stratification were modified by fish size and hunger level, with larger juveniles and those held on low rations spending more time in cold water. These behavioral responses correspond with the high feeding requirements necessary to maintain the naturally rapid growth rates of this species and the transitions in habitat associated with different life history stages.

The subtilisin BPN' variant, Sbt70, was cloned and expressed in Escherichia coli without the prodomain, the 77-residue N-terminal domain that catalyzes the folding of the enzyme into its native tertiary structure. Sbt70 has the high-affinity calcium-binding loop, residues 75 to 83, deleted. Such calcium-independent forms of subtilisin BPN' refold independently while retaining high levels of activity. Sbt70 has, in addition, seven stabilizing mutations, K43N, M50F, A73L, Q206V, Y217K, N218S, Q271E, and the active site serine has been replaced with alanine to prevent autolysis. The purified Sbt70 folded spontaneously without the prodomain and crystallized at room temperature. Crystals of Sbt70 belong to space group P2 sub(1)2 sub(1)2 sub(1) with unit cell parameters a = 53.5 angstrom, b = 60.3 angstrom, and c = 83.4 angstrom. Comparison of the refined structure with other high-resolution structures of subtilisin BPN' establishes that the conformation of Sbt70 is essentially the same as that previously determined for other calcium-independent forms and that of other wild-type subtilisin BPN' structures, all folded in the presence of the prodomain. These findings confirm the results of previous solution studies that showed subtilisin BPN' can be refolded into a native conformation without the presence of the prodomain. The structure analysis also provides the first descriptions of four stabilizing mutations, K43N, A73L, Q206V, and Q271E, and provides details of the interaction between the enzyme and the Ala-Leu-Ala-Leu tetrapeptide found in the active-site cleft.

All samples were tested for toxicity with a battery of complimentary laboratory bioassays. The laboratory bioassays consisted of amphipod survival tests in solid-phase sediments, microbial bioluminescence (Microtox(TM)) tests of organic solvent extracts, and sea urchin fertilization and embryo development tests of porewaters. Some samples also were tested in copepod reproduction and cytochrome P-450 RGS bioassays.

Observers using SCUBA estimated grouper populations at 13 patch reef sites. There appeared to be no significant effect from spear fishing on the relative abundance of the grouper species studied. Patch reefs protected from spear fishing had significantly greater sizes of individuals compared with unprotected patch reefs, probably because spear fishermen tend to target larger species and larger individuals. Spear fishing appears to have a greater influence on average size of groupers than on abundance. The slow growth and reproductive characteristics of groupers make them especially vulnerable to overfishing. The ban on spear fishing in some parts of the Florida Keys has significantly benefited the size distribution of groupers. A ban on spear fishing alone, however, has not enabled grouper population levels to recover. Establishment of a marine fishery reserve should be considered as a management measure to restore and conserve grouper assemblages.

In the drift gillnet fishery for swordfish and two shark species, seven of 387 mammals that became entangled were released alive. In the set gillnet fishery for halibut and angel shark, five of 1,263 entangled mammals were released alive. The estimated mortality for the drift gillnet fishery was more than 450 marine mammals each year, with common dolphins and northern elephant seals being the most commonly entangled. California sea lions and harbor seals were the most commonly entangled mammals in the setnet fishery. Twenty turtles and three seabirds were entangled in driftnets, and six turtles and 1,018 seabirds were entangled in setnets during the entire period. Estimated fluctuations in cetacean and pinniped mortality in these fisheries over the study period are reported. Area closure is the most likely reason for declines in the number of pinnipeds and cetaceans in the setnet fishery.

While dolphin population dynamics are not likely to be affected by such a change because of current low dolphin mortality, a change in the fishing pattern could lower commercial tuna stocks because school and log sets capture moderate to large amounts of undersize or other undesirable tuna that must be discarded. Differences between tuna discards in set types were examined during 1989-92. The increase in tons of tuna discarded per set that would likely result from replacing the dolphin sets with school or log sets was predicted to be 100 times higher (in terms of weight) for log sets and 10 times higher for school sets than for dolphin sets. Hypothetically, a total replacement could lead to a 337% increase in the average tuna discard over the whole fleet. Estimated discard increases for the yellowfin tuna are given. Continued removals of this degree could threaten long-term sustainability of tuna stocks.

Analysis of the maximum ice cover reveals (i) a low (1964-1976); (ii) a high (1977-1982); and (iii) once again a low (1983-1990) ice cover regime. The high ice cover regime corresponded in part with a hiatus in El Nino-Southern Oscillation (ENSO) events and the beginning of an interdecadal change in Northern Hemisphere atmospheric circulation that started in the late 1970s. About 46% of the lowest quartile ice covers occurred during the mature phase (year + one winter) of El Nino. Only 1 year out of seven with the mature phase of El Nino between 1963 and 1990 was not associated with the lowest quartile ice cover, this was 1977, a pivotal year after which a new climatic regime in the Northern Hemisphere was established. Anomaly maps of 700 hPa geopotential height for the lowest quartile ice cover reveal a zonal flow pattern. Highest quartile ice cover was associated with meridional circulation from the Arctic directed toward the Great Lakes. Significant differences occur for highest minus lowest quartile ice cover composite 700 hPa height anomaly maps in the Pacific Ocean, the west coast of North America, north Mexico, eastern North America, north central Siberia, western Europe and the adjacent North Atlantic. Correlations between first differences (year t + 1 minus year t) of annual maximum ice cover and 700 hPa geopotential heights for winters 1963-1990 agrees with these teleconnections and were higher than the absolute time series correlations, indicating strong interannual teleconnections. Annual maximum ice cover was also significantly correlated with the tropical Northern Hemisphere teleconnection index.

AN - 36401563; 6820 AB - PURPOSE: The implementation of a revised fishery management plan (FMP) for American lobsters in the exclusive economic zone (EEZ) along the North Atlantic coast in the Gulf of Maine, from southern Cape Cod to Long Island Sound, and along the Outer Continental Shelf from Georges Bank to North Carolina, is proposed. A June 1996 stock assessment conducted by state and federal scientists concluded that lobsters were overfished in all three stock assessment areas; the problem is aggravated by increased fishing effort, which will deplete stocks even further if unchecked. Six management alternatives for the trap/pot lobster fishery, including an alternative to maintain the status quo, are considered in this draft EIS. Alternative 2 would impose to continue current management measures in the EEZ and implement additional EEZ-wide regulations on maximum trap size and minimum vent size in lobster traps. Alternative 3 would establish a cap on the number of lobster traps permitted over a four-year period and would require lobster vessels to declare in which of three zones they intended to fish. Alternative 4 would impose a four-tier nearshore and offshore trap limit and require all federal lobster permit holders using traps to certify the number of traps they actually fished in 1997. Alternative 5 would establish trap limits in three fishing zones, and would require permit holders to designate in which zone they plan to operate. Alternative 6 would require the removal of all trap gear and closure of the EEZ to lobster fishing. Three additional alternatives are under consideration for lobster vessels using gear or methods other than traps. Additional alternative 1 would limit landings to 100 lobsters for each fishing trip of 24 hours or less. Additional alternative 2 would limit landings to no more than 500 lobsters per trip regardless of trip length. Additional alternative 3 would prohibit the fishing or possession of lobster by all methods of fishing. POSITIVE IMPACTS: The alternatives would protect the lobster industry from the effects of overfishing. The spawning stock size and yield per recruit would increase significantly. NEGATIVE IMPACTS: Restrictions on the use of lobster traps could create a temporary economic hardship for existing lobster operations.

AN - 36416016; 6805 AB - PURPOSE: The establishment of the Kachemak Bay National Estuarine Research Reserve, located in south-central Alaska, is proposed. The National Estuarine Research Reserve System, originally called the National Estuarine Sanctuary Program, is a federal-state cooperative venture. Federal matching grants are available to coastal states for the development and management of a national system of estuarine research reserves that are representative of the various regions and estuarine types in the United States. Federal financial assistance for development, operation, and management of the reserve has been requested by the state of Alaska. The Kachemak Bay region has high productivity, an abundance and diversity of organisms, and an array of diverse habitats. A great variety of terrestrial, wetland, and aquatic habitats are incorporated within the proposed boundaries of over 365,000 acres. The bay exhibits very high primary production in the water column due to an upswelling of oceanic water entering the bay through Cook Inlet. The nutrient-rich environment provides critical habitat for numerous species during various life phases. Four alternatives, including a No Action Alternative, are considered in this draft EIS. Under the preferred alternative, the reserve would be used primarily for education and research purposes, particularly as a tool for improving coastal decision making. Traditional uses within the boundaries of the reserve would continue to be regulated by existing local and state laws and site owner policies. Fish and wildlife scientists would be brought together with other environmental scientists, educators, and managers to operate their estuarine and coastal management programs from an education and research center located on the reserve. A collaborative management approach would be implemented, involving advisory committees, landowners, private organizations, and local, state, and federal agencies. Reserve staff would include a program manager, a research coordinator, an education coordinator, and necessary administrative support staff. POSITIVE IMPACTS: The educational program of the proposed reserve would increase public awareness of the estuarine resources in the Aleutian Island subregion. A research plan associated with the reserve would establish a baseline monitoring program for the estuarine area, and would encourage research projects consistent with the reserve's role as a protected natural field laboratory. The research program would provide information useful for better management of estuarine resources. NEGATIVE IMPACTS: None.

AN - 36389801; 6803 AB - PURPOSE: The implementation of an ecosystem restoration and water management program for the San Francisco Bay and Sacramento-San Delta, located in northern California, is proposed. The program area extends from southern to northern California and includes the lowlands and uplands in the Sacramento and San Joaquin River watersheds; Suisun Bay and Marsh, San Pablo Bay, and the San Francisco Bay watershed; and Tulare Lake, Consumnes River, Mokelumne River, and other rivers and waterways connected to the San Joaquin River. The bay-delta region itself refers to the 738,000-acre area south of the city of Sacramento where the Sacramento and San Joaquin rivers meet, an environmentally diverse area that supports 750 plant and animal species within the largest wetlands area in the western United States. The region also provides water to two-thirds of the state's residents and much of its agricultural industry. In recent years, the bay-delta region has experienced a steady decline as a fish and wildlife habitat and as a reliable source of water because of population increases and economic development pressures. The CALFED program was established in June 1995 by 15 state and federal agencies in order to address the complex issues affecting the bay-delta region. Four alternatives, including a No Action Alternative, are considered in this draft programmatic EIS. Each of the action alternatives would include a core program that would address the issues of ecosystem restoration, water use efficiency, water quality, Delta levee and channel integrity, water transfers, watershed management coordination, and a range of storage and conveyance options. Storage options would include 3.0 million acre-feet (MAF) surface storage on Sacramento River tributaries upstream of the delta, 500 thousand acre-feet (TAF) of storage on San Joaquin River tributaries, two MAF of storage off-aqueduct south of the delta, 200 acre-feet in-delta storage, and 250 and 500 TAF of groundwater storage in the Sacramento and San Joaquin valleys, respectively. Conveyance options would include relying on the existing system while making some minor changes in the south delta, enlarging channels within the delta, and a conveyance channel for moving water around the delta. POSITIVE IMPACTS: The program would help to restore a vital wetlands area, lower toxicants in the water system, conserve over three million acre-feet of water by the year 2020, strengthen levees throughout the Delta, reduce drought-induced economic damage by improving flows from one region to another, and improve overall watershed management. NEGATIVE IMPACTS: The construction of storage and conveyance facilities would have an adverse short-term effect on water quality and an adverse long-term effect on fish habitat and migration. Increased water conservation for ecosystem restoration would reduce water availability for agricultural and municipal uses during drought conditions. Air quality would be adversely affected for a short period. Vegetation and wildlife communities would also be adversely affected. Farmland and other agricultural land would be converted, and job losses could occur. The project could include significant visual impacts.

Thus the Eighteenth edition was hosted by the Mazatlan Research Unit of the Instituto de Ciencias del Mar y Limnologia of the Mexican National Autonomous University (UNAM) in Mazatlan, Sinaloa (Mexico) where it was held from 3-7, March, 1998. Above all, our symposium is prominent for its dynamism and enthusiasm in bringing together specialists from the world's sea turtle populations. In an effort to extend this philosophy, and fully aware of how fast the interest in sea turtles has grown, the organizers paid special attention to bring together as many people as possible. With the tremendous efforts of the Travel Committee and coupled with a special interest by the Latin American region's devotees, we managed to get 653 participants from 43 countries. The number of presentations increased significantly too, reaching a total of 265 papers, ranging from cutting-edge scientific reports based on highly sophisticated methods, to the experiences and successes of community-based and environmental education programs.

AN - 21103955; 11287748 AB - The natural sex ratios of sea turtles have been of interest since the discovery of temperature-dependent sex determination (TSD) in sea turtles (Owens and Hendrickson, 1978). It is possible that the sex ratio within a management unit is dynamic, varying among cohorts. Studies have shown that adult populations are difficult to evaluate for sex ratios due to various sex-determined behaviors (Wibbels et al., 1987). Likewise, the sex ratios of hatchling populations can vary depending upon the geographic location or the time of year (i.e., incubation temperature) the eggs are laid. In theory, an immature stage of a sea turtle population has not developed such behavior biases and is thus more likely to reveal the actual sex ratio for that population. In addition, the benthic immature life stage represents a condensation of many years of hatchling production (Wibbels et al., 1987). Interestingly, most sex ratios of sea turtle populations described to date have been fairly close to 1:1, or up to a bias of about 1.9:1 (Owens, 1996).

Foraging takes place on several kinds of benthic algae (Acanthophora, Hypnea, Codium, Amansia) as well as Halophila hawaiiana, the sole sea grass in the Hawaiian Islands. Green turtles in Kaneohe Bay rest underwater in muddy channel bottoms and in crevices associated with patch-reef pinnacles and other calcareous habitats (Brill et al., 1995). Numerous smooth depressions and undercuts have been created in the coral from repeated use by resting turtles. Buoyant fecal pellets from turtles inhabiting Kaneohe Bay regularly wash ashore, occasionally in great numbers (Balazs et al., 1993).

Additionally, none of the work reported to date has taken place in the Pacific region (Byles and Swimmer, 1994, Groshens and Vaughn, 1994). In the Hawaiian Islands the hawksbill, known as honu'ea, is a rare and endangered species (Balazs, 1978; Balazs et al. 1992; 1994). An estimated total of not more than 30 females nest in the best of years at 10 beach sites found exclusively on the islands of Hawaii, Maui, Molokai and Oahu. Hawksbills are not known to reside or nest in the Northwestern Hawaiian Islands, where green turtles, Chelonia mydas (honu), seasonally migrate to breed from throughout the archipelago (Balazs, 1976).

Although several infectious agents (herpesvi-rus, retrovirus and papillomavirus) have been associated with the condition, the etiologic agent has not been isolated or characterized. FP has been reported worldwide in green turtles and it has been recently reported in other turtle species, including loggerheads (Caretta caretta) in Florida and olive ridleys (Lepidochelys olivacea) from the Pacific coasts of Mexico and Costa Rica. Normal skin (6) and tumor (41) biopsies were collected from 25 adult female olive ridleys in Ostional, Costa Rica, between July and September 1997. Grossly, biopsies were small, white to grey, smooth to verruciform, raised masses on the integument of the neck and flippers. All 41 masses were 25 mm or less in diameter and histologically, 8/41 masses were small foci of chronic active dermatis and not tumors; and 33/41 were diagnosed as fibropapillomas. Twelve of 33 tumors were regressing and 9 of the remaining 21 tumors had early histological changes that suggested degeneration within the tumor. During field surveys based on gross lesions, prevalences of 1-10% have been reported in this nesting population. This is considered the first diagnostic confirmation of FP in olive ridley turtles.

These HSI modeling methods are based on an approach developed by the U.S. Fish and Wildlife Service which calculated the value of an area by determining what a species needed from its habitat, followed by quantification of habitat availability. SEA Division has adapted this approach to address estuarine and marine issues, adding a spatial component utilizing GIS technology. This Kemp's ridley HSI model represents an exploratory analysis of the potential use of HSI in sea turtle management and speculative distribution and density research using currently available data.

Such turtles have been referred to as "Barnacle Bills". However, no evidence has been presented to link epibiota load and health status conclusively. During November 1997, 56 loggerhead sea turtles, 50-70 cm SCL, were sampled from Pamlico and Core Sounds, N.C., U.S.A. Turtles were measured, barnacles were counted, epibiota were sampled to enable subsequent identification, and turtles were photographed and shell and epibiota patterns were analyzed with image analysis. Blood samples were drawn at capture and 29 blood parameters were analyzed. Hypotheses tested included (l)epibiota load does not increase as a function of turtle length, (2)epibiota load does not vary between sex in juveniles, and (3) epibiota load is not an indicator of the health of the turtle.

AN - 21096658; 11287690 AB - Surveys conducted since 1988 have underscored the importance of North Carolina's inshore waters, particularly the Pamlico-Albemarle Estuarine Complex, to juvenile loggerhead (Caretta caretta), green (Chelonia mydas), and Kemp's ridley (Lepidochelys kempii) sea turtles. Sea turtles are present in the Complex April-December. During their emigration in fall and early winter, the turtles are vulnerable to capture in pound nets set behind the barrier islands. Pound nets, as set in N.C., are a passive gear that allows turtles to feed and to surface to breathe. The Core Sound and eastern Pamlico and Albemarle Sounds area was established as a pilot index area for sea turtles in 1995, using catch rates in pound nets as an index of abundance. The feasibility and methodology was established and the fishery was sampled again during fall 1996 and 1997. The goal of this 3-yr project was to establish the area as an index abundance area to monitor, assess, and predict the status of and impacts to sea turtles and their ecosystems. The cooperation of pound net fishermen in the area provides data not only on abundance, but also on movement and demography of these populations. In additions, blood samples were utilized for analyses of health status, sex, and genetics.

Observations on courtship and mating in leatherbacks are almost non-existent, although sea turtles are generally presumed to be promiscuous based on extensive studies of green turtles (Alvarado and Figueroa, 1991). FitzSimmons (1996) surprisingly found that multiple paternity was rare in Australian greens. Leather-back paternity studies to date have been invalid due to an insufficient number of reliable polymorphic loci. We have identified informative new microsatellite loci, and have sampled successive clutches laid by the same females over a three month period in St. Croix, U. S. Virgin Islands. A total of 6 loci were used to construct the genotypes of nesting females and their offspring. Loci were amplified by PCR using fluorescent dye-labelled primers analyzed on a 377A ABI automated sequencer with GENESCAN. Paternal genotypes were inferred by comparing the known offspring and known maternal genotypes. Using allele frequencies for the St. Croix nesting population, the probability of detecting multiple paternal alleles (d) was determined for each locus and across all loci (D) (see FitzSimmons, 1996). The probability of detecting multiple paternity was relatively low for some individual loci (DC99 and N32 in particular), combined D for all 6 loci was 99%. Analysis of data from a total of 178 hatchlings from series of 3 to 5 clutches (n=17 total) laid by each of 4 females, did not reveal any evidence of multiple paternity. Unexpected paternal alleles were detected in four cases; however, since in each case these alleles were only present at one locus, they were considered to be mutations rather than contributions by a second male. Two instances of mutation of the maternal allele were also detected in this way. Mutation rates were highest in DC2-95, one of the most polymorphic loci. The lack of multiple paternity in this study corroborates previous findings with microsatellites for green turtles in Australia (FitzSimmons, 1996), and suggests either that female leatherbacks rarely mate with multiple males (perhaps as a result of behavioral factors, like competition, or because they rarely encounter them), or that sperm competition occurs. Either scenario would require the ability to store sperm. The detection of mutation within one generation turnover emphasizes the importance of using multiple loci when attempting to detect multiple paternity with microsatellites. Samples from additional females are presently being analyzed.

The Hawaiian Archipelago includes 132 islands and reefs extending for 2400 km across the North Pacific. However, the eight main islands at the southeastern end of the chain account for nearly all coastal benthic habitats suitable for foraging and resting by post-pelagic green turtles. Adult males and females residing throughout the chain migrate to breed at isolated French Frigate Shoals (23 degree 47'N, 166 degree 12'W) situated at the mid-point of the archipelago (Balazs, 1976, 1980, 1983). Systematic monitoring at tins site for 23 consecutive seasons (1973-95) has documented an approximate threefold increase in the number of nesting females (Fig. 1). This encouraging sign of population recovery is attributed to protection extended in 1978 under the U.S. Endangered Species Act. Similar increases have been seen for immature turtles inhabiting nearshore waters of the main islands, such as reported here for Kiholo Bay.

Development of the coastal strand and the resulting placement of structures on the primary and secondary dune (or equivalent), are the first steps toward coastal armoring. Coastal armoring is exhibited in many different forms. For the purpose of this paper, and with marine turtles specifically in mind, we offer the following definition of coastal armoring. Coastal armoring is any rigid or frangible structure placed parallel to the shoreline on the upper beach with the sole purpose of protecting upland structures or property. Other structures (i.e., groins, jetties) also present threats to marine turtles and their nesting habitat, but are outside the scope of this paper.

The purpose of this study was to locate resident foraging pastures utilized by the turtles, and to determine the routes taken to reach these sites. The hawksbill is a rare and endangered species in the Hawaiian Islands where it has recently been the focus of increased research and recovery efforts. Nesting is confined to only a few beaches on the islands of Oahu, Molokai, Maui and Hawaii in the southeastern segment of the archipelago. Sightings by ocean users of immature or adult hawksbills are uncommon in marine habitats of the Hawaiian Islands. In contrast, green turtles, Chelonia mydas, are numerous and routinely encountered by divers and tour operators promoting the underwater viewing of sea turtles.

ER - TY - JOUR T1 - NESTING BEACH SURVEYS: THE IMPORTANCE OF COMPLETE DATA REPORTING AN - 21081316; 11287681 AB - Nesting beach surveys are the most widely implemented monitoring tool in use by the global sea turtle community and are an important component of a comprehensive program to assess and monitor the status of sea turtle populations. These assessments are necessary to evaluate the effects of recovery and conservation activities which are being implemented at all life history stages. Monitoring techniques employed on nesting beaches range from highly structured standardized sampling to 'snapshots' of nesting activity within a nesting season. While nesting surveys are currently widespread, the variability in techniques often hampers our ability to make meaningful assessments of the status of nesting populations. Problems may occur when attempting to assess the status of nesting populations within nesting seasons but between survey areas, between and among nesting seasons at a particular nesting site, and/or across some nesting range of a particular population or stock (e.g. within country or state). With these problems in mind, the principal purpose of this paper is to emphasize the importance of reporting complete information when presenting nesting beach survey data, in order that those data may be used appropiately for both management and research purposes.

AN - 21081298; 11287675 AB - Missing from estimates of adult population size and health of sea turtle populations are the numbers of males contributing to the next generation. Peare (1994) used genetic analysis (multi-locus minisatellite probes) to demonstrate multiple paternity in green turtle clutches at Tortuguero. Mixed reports at subsequent turtle symposia have indicated that the incidence of multiple paternity varies from species to species and perhaps location to location. This study uses microsatellites to examine the paternal contribution to loggerhead clutches laid on Melbourne Beach, FL in the summer of 1996. Blood was collected from 150 mothers, and scute biopsies were taken from 1341 offspring from 89 clutches. Samples were collected at two locations which are approximately eight kilometers apart, one within and one just north of the Archie Carr National Wildlife Refuge. The genotypes of the mothers were ascertained at four polymorphic microsatellite loci: Cc141, Ei8 (FitzSimmons et al. 1995), Cc7, and Cc117 (FitzSimmons, 1997). The two most polymorphic of these loci (Cc7 and Cc141) were then selected to estimate the levels of multiple paternity in 38 clutches.

As such it is an important habitat for sea turtles including the threatened loggerhead sea turtle (Caretta caretta). The ledges and overhangs of the reef provide the loggerhead sea turtle with protected resting spots, a bountiful resource of food, and close proximity to nesting sites on barrier island beaches. The National Oceanic and Atmospheric Administration (NOAA) manages Gray's Reef and the other national marine sanctuaries to protect their natural resources. For each sanctuary, a management plan is developed to encourage compatible public uses, and to promote scientific understanding and public awareness of the marine environment. Gray's Reef National Marine Sanctuary is located 32 kilometers (17.5 nautical miles) off Sapelo Island, Georgia and encompasses 58 square kilometers (17 sq. nautical miles) of live-bottom habitat's Reef is a submerged hard bottom (limestone) area that, as compared to surrounding areas, contains extensive but discontinuous rock outcropping of moderate (3 meters) height with sandy, flat-bottomed troughs between. The series of rock ledges and sand expanses has produced a complex habitat of caves, burrows, troughs, and overhangs that provide a solid base for the abundant sessile invertebrates to attach and grow. This rocky platform with its carpet of attached organisms is known locally as a "live bottom habitat". This topography supports an unusual assemblage of temperate and tropical marine flora and fauna. Algae and invertebrates grow on the exposed rock surfaces: dominant invertebrates include sponges, barnacles, sea fans, hard coral, sea stars, crabs, lobsters, snails, and shrimp.

AN - 80019295; 9676252 AB - Hydropic vacuolation (HydVac) of biliary epithelial cells and hepatocytes is described for 3 species of U.S. West Coast bottom fishes. Risk assessment analyses are also conducted to determine if the prevalence of this lesion increases in association with contaminant exposure and site of capture. The morphology of HydVac in starry flounder Platichthys stellatus, white croaker Genyonemus lineatus and rock sole Lepidopsetta bilineata was similar to that described in winter flounder Pleuronectes americanus from the U.S. Atlantic Coast, especially in that HydVac most commonly affected biliary epithelial cells. Hydropic vacuolation was the most prevalent liver lesion in starry flounder and white croaker captured from contaminated environments. Risk assessment analyses confirmed that the relative risk for HydVac increased with the presence of aromatic and chlorinated hydrocarbons in sediment, fish bile, and fish liver for these species. Hydropic vacuolation also frequently occurred in rock sole, but the lesion showed no clear association with contaminant exposure in this species. The types of liver lesions that were useful biomarkers of contaminant effects in fish depended on the species and this factor must be taken into account when evaluating histopathological biomarkers of response to contaminant exposure.

The radar has a pencil beam, a high power, and a wavelength of 10 cm. It transmits horizontally and vertically polarized waves alternately. The available polarimetric variables are differential reflectivity, differential phase, and correlation coefficient between orthogonally polarized returns. Two types of biological scatterers, insects and birds, are contrasted. Observed polarimetric signatures of these are compared and explained with a simple scattering model. Finally, we discuss the implications of recognizing the biological scatterers' type and the size of birds.

LAPS is a complete, three-dimensional data assimilation system that produced subhourly atmospheric analyses on an 8-km grid covering all the Olympic venues. The LAPS analyses also provided initial conditions to the Regional Atmospheric Modeling System (RAMS) mesoscale forecast model. RAMS forecasts were generated at least every 3 h using 8- or 2-km grids. For the first time, a comprehensive operational analysis and forecast system operated in a local NWS forecast office to support meso- beta -scale forecasts and warnings. Numerous benefits of LAPS-RAMS to the local forecast office were demonstrated. The OWSS, with LAPS-RAMS included, provided a precursory view of the enhanced operational mesoscale forecast capabilities that can be available to the NWS and other forecast offices in the near future.

Annual Statistical Summary for the 1995 EMAP-Estuaries Demonstration Project in the Carolinian Province AN - 17659730; 4466665 AB - A study was conducted to assess the environmental condition of estuaries in the EMAP Carolinian Province (Cape Henry, VA - St. Lucie Inlet, FL). A total of 87 randomly located stations was sampled from July 5 - September 14, 1995 in accordance with a probabilistic sampling design. Wherever possible, synoptic measures were made of: (1) general habitat condition (depth, physical properties of water, sediment grain-size, organic carbon content), (2) pollution exposure (sediment contaminant concentrations, sediment toxicity, low dissolved oxygen conditions in the water column, ammonia and sulfide in sediment porewater), (3) biotic conditions (diversity and abundance of macroinfauna and demersal biota, pathological disorders in demersal biota), and (4) aesthetic quality (presence of anthropogenic debris, visible oil, noxious sediment odor, water clarity). Percentages of degraded vs. undegraded estuarine area were estimated based on these various environmental indicators. The data also were compared to results of a related EMAP survey conducted in 1994 in this same region as part of a multi-year monitoring effort.

N1 - Last updated - 2015-03-24 ER - TY - JOUR T1 - Modelling estuarine eutrophication in the context of hypoxia, nitrogen loadings, stratification and nutrient ratios AN - 17577619; 4486666 AB - Estuarine eutrophication is a serious ecological and economic problem. Hypoxic waters resulting from decomposing phytoplankton in stratified bottom-waters are often associated with estuarine eutrophication, with the degree of the phytoplankton accumulation and subsequent decomposition corresponding to the phytoplankton's density in the overlying water. In general, high phytoplankton densities occur when nutrient availability is high enough to maintain the phytoplankton population. High nutrient availabilities generally result from high nutrient loads entering estuaries from their watersheds. Therefore, the co-occurrence of stratified bottom-waters and high nutrient loadings predisposes estuaries to developing hypoxic bottom-waters. This paper presents a multinominal logistic regression model that predicts the status of estuaries as normoxic, borderline hypoxic, hypoxic and severely hypoxic based on nitrogen loadings, salinity stratifications and 'phosphorus to nitrogen' load ratios. The model was applied to 10 US Gulf of Mexico estuaries and it correctly assigned eight of the 10 estuaries to their correct eutrophication status. Summaries of each estuary's probabilities for being normoxic, borderline hypoxic, hypoxic or severely hypoxic are presented along with their modelled responses to changes in nutrient loadings. Other model results include nutrient loading reductions associated with moving hypoxic and severely hypoxic estuaries into the normoxic and borderline status. This estuarine eutrophication model follows previously developed eutrophication models for lakes which were based on similar premises and have been successfully used to develop management policies. The estuarine eutrophication modelling approach provides a platform for evaluating nutrient reduction management strategies in the context of an estuary's modelled response to proposed nutrient reductions. Therefore, the modelling approach presented here is offered in support of developing management policies concerning estuarine eutrophication.

The CSTP was initiated in 1962 at the Sandy Hook Laboratory in New Jersey under the Department of Interior's U.S. Fish and Wildlife Service (USFWS). During the late 1950's and early 1960's, sharks were considered a liability to the economy of resort communities, of little or no commercial value, and a detriment to fishermen in areas where sharks might damage expensive fishing gear or reduce catches of more commercially valuable species. Several shark attacks along the New Jersey coast at that time gave rise to public concern about a perceived shark menace. In response to that concern, a shark longline survey was conducted in 1961 from Jones Inlet, N.Y., to Cape Henlopen, Del., by laboratory staff. The objectives of that study were to determine the species composition, distribution, abundance, food habits, seasonal occurrence, and other aspects of the biology of large sharks off the middle Atlantic states.

Seagrass beds in this area form patterns ranging from continuous to semi-continuous to widely dispersed, discrete patches across a gradient of increasing hydrodynamic activity. Tidal current speeds, exposure to waves and relative water depths revealed strong correlative evidence that physical processes influenced landscape-scale (50 x 50 m range with 1 m resolution) features of seagrass beds. Some habitat attributes, such as percent cover of seagrasses, seagrass bed perimeter to area ratio, sediment organic content and percent silt-clay, declined with increasing REI and current speed. Increased aggregation of these data was observed above and below the 50% seagrass cover value, and, supported by principle components analysis, signaled an abrupt transition of environmental setting correlated with this coverage level. The 50% cover value also occurred at current speeds of similar to 25 cm s super(-1), which should be near the initiation of motion current speed for local sand sediments, and an REI of similar to 3 x 10 super(6). This coverage is also near to the 59.28% coverage value, previously determined to be where landscape elements join and below which they tend to exist as discrete patches. We hypothesize that a rapid loss of seagrass habitat structural integrity may occur as the habitat fragments, and seagrass landscape elements become isolated, contributing to the observed transition and accompanying data aggregation above and below the similar to 50% coverage level. We discuss the interaction of physical setting, disturbance, landscape contiguity and growth response by these modular plants in the production of the observed landscape patterns across these hydrodynamic gradients.

Based on in situ marking experiments, we determined that the first 3 or 4 leaves on a short-shoot are produced in less than or equal to 45 d; thereafter new leaves are formed about every 40 d. We were able to confirm this estimate of leaf plastochrone interval (leaf Pl) by examining the alternating internodal sequences resulting from differential growth of the vertical stems. Analysis of short-shoot age in leaf Pl versus frequency histograms also indicated that each short-shoot produces approximately 12 leaves during the first year of growth and 9 leaves each year thereafter. Short-shoot age is skewed toward younger ages, with a median short-shoot age of approximately 0.6 yr, maximum age of 3.5 yr, and very few short-shoots living beyond 2.5 yr. Short-shoot recruitment appeared nearly continuous during the 3 yr study period. The vertical stem internodes were very large, ranging in length from 0.1 to 7.5 cm and averaging 2.1 cm. Vertical stem growth was independent of the sediment surface, raising photosynthetic tissue 25 to 60 cm above the sediments and forming a multidimensional shoot canopy at an average rate of 17 cm yr super(-1). We determined that during the first year of life short-shoots could produce upwards of 25 cm of vertical stem. The vertical stem growth rate of S. filiforme is, therefore, among the highest reported for any species of seagrass. The developing techniques of seagrass demography proved to be valuable tools for analyzing the growth dynamics and population structure of S. filiforme in outer Florida Bay.

The global distribution of N sub(2)O production in rivers and estuaries was modeled as a function of nitrification and denitrification rates, which were related to external nitrogen (N) inputs. N loading rates were estimated as a function of environmental parameters in the watersheds using two existing models that we adapted for global databases. Model estimated export of dissolved inorganic nitrogen (DIN) by world rivers to estuaries in 1990 is 20.8 Tg N yr super(-1); approximately 75% is estimated to be anthropogenic. DIN export to the Atlantic and Indian Oceans is similar (5.4 Tg N yr super(-1) and 4.6 Tg N yr super(-1), respectively); inputs to the Pacific are approximately 50% greater. China and southeast Asia account for over 50% of DIN export by world rivers. Globally, anthropogenic DIN export is predominately attributed to fertilizer N, followed by sewage and atmospheric deposition. About 8% of the total N inputs to the terrestrial environment can be accounted for as DIN export by rivers. Worldwide N sub(2)O emissions from rivers (55%), estuaries (11%), and continental shelves (33%) are calculated to be 1.9 Tg N yr super(-1). For rivers and estuaries, approximately 90% of N sub(2)O emissions are in the northern hemisphere in line with the regional distribution of DIN export by rivers. China and India account for about 50% of N sub(2)O emissions from rivers and estuaries. About 1% of the N input from fertilizers, atmospheric deposition, and sewage to watersheds is lost as N sub(2)O in rivers and estuaries. Globally, rivers and estuaries could account for approximately 20% of the current global anthropogenic N sub(2)O emissions and are similar in magnitude to a number of previously identified sources including direct emissions of N sub(2)O from soils induced by anthropogenic N inputs.

Restoration Project 96012A-2. EXXON VALDEZ Oil Spill. Restoration Project Final Report AN - 17164973; 4467788 AB - In Prince William Sound, predation by killer whales occurs on at least three injured resources: harbor seals (Phoca vitulina), salmon (Onchorhynchus sp), and herring (Clupea pallasi). To predict the relative impact that killer whale predation may have on these injured resources, the level of predation and the relative proportion of each species consumed by killer whales must be quantified. Current information on the feeding habits of killer whales are based either on observatons of feeding events or examination of stomach contents of stranded whales. The current paradigm is that transient whales feed primarily on marine mammals and that resident whales feed on fish. The objective of the present study was to assess whether stable isotope signature analysis and fatty acid signature analyses could be applicable in the resolution of this problem. This preliminary attempt was designed to ascertain whether standard biopsy samples, which are commonly derived for genetic analysis, would be appropriate for use in the assessment of feeding habits using these techniques.

These rates (r sub(2M)) are used as a measure of the relative ability of different sharks to recover from fishing pressure. The method incorporates concepts of density dependence from standard population modelling and uses female age at maturity, maximum reproductive age, and average fecundity. A compensatory response to population reduction is assumed in pre-adult survival to the extent possible given the constraints of the life-history parameters. 'Rebound' productivity was strongly affected by age at maturity and little affected by maximum age. Species with lowest values (r sub(2M) 0.08) were small coastal, early-maturing species. Sharks with mid-range values (r sub(2M) = 0.04-0.07) were mostly large (> 250 cm maximum size) pelagic species, relatively fast growing and early maturing. Possible selection pressures for these three shark groups, management implications, practical applications for the derived parameter r sub(2M), and recommended areas of research are discussed.

Two common zooplankton species, the euphausiid Euphausia pacifica and the copepod Calanus pacificus, consumed diverse types of field-collected marine snow, including diatom flocs, abandoned larvacean houses, and dinoflagellate aggregates, regardless of their composition, C:N ratio, age, or the availability of alternate dispersed food. Ingestion rates of aggregates by E. pacifica increased with increasing marine snow concentration, although in situ concentrations of aggregates were not sufficient to elicit a maximum ingestion rate. Ingestion rates of aggregates by E. pacifica at higher aggregate concentrations were from 9 to 15 mu g C euphausiid super(-1) h super(-1). Assimilation efficiencies of euphausiids grazing on marine snow were 83% (dinoflagellate snow) and 64 to 75% (diatom/larvacean house snow). These results indicate that marine snow can be an important food source for marine zooplankton and that consumption of large aggregates is likely to play a role in the cycling of carbon and the structure of food webs in the pelagic zone of the ocean.

This species is harvested commercially. Shell length and age data were collected for this species from 1980 to 1994 during surveys of population size and structure. These data were used to examine the relationship between the growth rate of S. solidissima and intraspecific density. The null hypothesis was that density (represented by number of individuals per tow) would have no effect on rate of growth. A negative relationship would support the alternative hypothesis, that intraspecific competition had taken place. This analysis focused on the surfclam population offshore from the Delmarva Peninsula, USA because: (1) a major recruitment event occurred in 1977, (2) clam fishermen had reported "stunted" surfclams in that area, (3) a wide range of local densities were available to examine, and (4) the existence of a closed area within the study area set up an interesting contrast with areas left open to harvesting. Maps of surfclam abundance across the Delmarva region demonstrate that areas of highest density have generally remained in the same location through time. The results suggested that intraspecific competition has been important in structuring this population. Based on data from 1980 to 1992, shell length was significantly reduced at high density, and a significant interaction between age and density was observed. Growth modeling indicated decreased asymptotic lengths and growth rates with increasing density. In nine out of ten pairwise randomization tests, fitted von Bertalanffy growth curves, representing different densities, were significantly different from each other. High densities of clams have persisted in the area that was closed to harvesting for 11 years (1980 to 1991). In 1994, length at age was significantly less in this closed area compared to that in the surrounding area. This effect was apparent in clams from 3 to 17 years of age, and most pronounced in the cohort that recruited to the Delmarva region in high numbers in 1977. Lower growth rates within the closed area have management implications for the optimal duration of closures.

Those sequences had been used to identify the two types of Xyrichtys larvae as X. novacula, but owing to the contamination, the identifications are invalid. Fresh specimens were collected: X. martinicensis (Curvier and Valenciennes), X. novacula, X. splenders (Castelnau), and Xyrichtys sp. larvae of each of the two morphotypes (dorsal-forward eye and ventral-forward eye). The cytochrome b fragment was amplified from each specimen using the polymerase chain reaction. Comparison of the sequences with human cytochrome b sequence confirmed that the new sequences were not contaminated. The interspecific differences in Xyrichtys sequences were less than previously reported, but still greater than observed in many fish genera. Distance and parsimony analyses indicated that X. novacula and X. martinicensis were more closely related to each other than to X. splendens. This conclusion differs from our previous conclusion that X. martinicensis and X. splendens were more closely related to each other than to X. novacula. Distance and parsimony analyses also demonstrated that both larval morphotypes were X. novacula and, thus, our previous conclusions regarding larval ecology and oceanographic transport remain unchanged.

Changes in fish health bioindicators after 90 days, i.e., increases in fin erosion, liver lipidosis, gill hyperplasia, and gill parasites, coupled with decreases in macrophage aggregates, occurred at hydrocarbon concentrations (1600 mu g/g) that reduced growth 34-56% among the flatfishes. Chronic hydrocarbon pollution of nearshore nursery sediments could alter growth and health of juvenile flatfishes. Recruitment of juveniles to the fishery may decline because of increased susceptibility to predation and slower growth.

Age-0 walleye pollock Theragra chalcogramma appeared to be frequently associated with these gelatinous zooplankton. During daytime, up to 30 pollock were observed swimming within the tentacles of these medusae, but when approached by the ROV, the pollock generally left the vicinity of the jellyfish. At night, few such associations were observed and juvenile pollock moved closer to the surface, apparently feeding in loose aggregations, while the medusae remained close to the thermocline (35-40 m). Prowfish Zaprora silenus were also observed near large medusae, but tended to be found closer to the bell rather than within the tentacles. The lack of any gelatinous material in the stomachs of the pollock suggests that juvenile pollock associate to gain shelter from predation or possibly as a thigmotactic response to biotic structure. The implications of this commensal behavior with gelatinous zooplankton are discussed relative to pollock recruitment in the Eastern Bering Sea.

Experiments were performed at the Organization for Tropical Studies (OTS) Palo Verde Biological Station (10 degree N, 85 degree W), Guanacaste Province, Costa Rica during the dry season on 13-14 February 1993. Acacia collinsii, Pseudomyrmex spinicola, P. nigrocinctus, and P. flavicornis are common in dry sites near the biological station. Only trees with a diameter at breast height of at least 3 cm were used because they had sufficiently established ant colonies. Trees of the proper size were selected haphazardly by flagging the first 42 trees with separate Pseudomyrmex spinicola or P. nigrocinctus colonies and the first 42 trees with separate P. flavicornis colonies that were encountered.

The precipitation anomaly over the west coast of North America shows a north-south three-cell pattern. Heavy precipitation in California is accompanied by dry conditions over Washington, British Columbia, and along the southeastern coast of Alaska and reduced precipitation over the subtropical eastern Pacific. The inverse relationship between California and the Pacific Northwest is supported by the transport of moisture flux. During wet events, the southern branch of moisture flux transport strengthens and brings moisture from the North Pacific to California, hence enhanced rainfall. Strengthened moisture flux transport northward to the area north of Washington is consistent with suppressed rainfall in California. The local precipitation anomaly pattern in the eastern tropical Pacific just north of the equator has a large influence on precipitation events in California. The enhanced precipitation generates strong rising motion. The associated sinking motion is located over California. Strong sinking motion and strong upper-level convergence favor dry conditions in California. Conversely, suppressed rainfall in the eastern Pacific is associated with above-normal precipitation in California. Precipitation in California is likely below normal during cold ENSO events. When convection in the central Pacific is enhanced, California has heavy precipitation if rainfall in the subtropical eastern Pacific is suppressed. In addition to ENSO, precipitation in California is also modulated by the tropical intraseasonal oscillation. Wet (dry) events are favored during the phase of the oscillation associated with enhanced convection near 150 degree E (120 degree E) in the tropical Pacific.

Female school mackerel (L sub( arrow left ) = 651 mm, K = 0.59, t sub(0) = -1.41) were estimated to grow to a greater asymptotic length, but at a slower rate, than males (L sub( arrow left ) = 628 mm, K = 0.71, t sub(0) = -1.26). Growth patterns of school mackerel differed between geographic regions and suggested the existence of separate stocks throughout the east-coast distribution. In contrast, female spotted mackerel (L sub( arrow left ) = 849 mm, K = 0.46, t sub(0) = -1.54) were estimated to reach a greater asymptotic length at a faster rate than males (L sub( arrow left ) = 768 mm, K = 0.23, t sub(0) = -4.33). There was no difference in growth between spotted mackerel from different regions, suggesting that there is a single stock along the Queensland east coast. Identification of school and spotted mackerel populations in Queensland east-coast waters will enable the species to be managed on the basis of stock structure across this range.

A 16-residue Omega -loop deletion mutant of beta -lactamase from Staphylococcus aureus PC1, encompassing residues 163-178, was produced in order to examine the functional and structural role of the loop. The crystal structure was determined and refined at 2.3 angstrom, and the kinetics of the mutant enzyme was characterized with a variety of beta -lactam antibiotics. In general, the wild-type beta -lactamase hydrolyzes penicillin compounds better than cephalosporins. In contrast, the deletion of the Omega -loop led to a variant enzyme that acts only on cephalosporins, including third generation compounds. Kinetic measurements and electrospray mass spectrometry revealed that the first and third generation cephalosporins form stable acyl-enzyme complexes, except for the chromogenic cephalosporin, nitrocefin, which after acylating the enzyme undergoes hydrolysis at a 1000-fold slower rate than that with wild-type beta -lactamase. Hydrolysis of the acyl-enzyme adducts is prevented because the deletion of the Omega -loop eliminates the deacylation apparatus comprising Glu166 and its associated nucleophilic water site. The crystal structure reveals that while the overall fold of the mutant enzyme is similar to that of the native beta -lactamase, local adjustments in the vicinity of the missing loop occurred. The altered beta -lactam specificity is attributed to these structural changes. In the native structure, the Omega -loop restricts the conformation of a beta -strand at the edge of the active site depression. Removal of the loop provides the beta -strand with a new degree of conformational flexibility, such that it is displaced inward toward the active site space. Modeled Michaelis complexes with benzylpenicillin and cephaloridine show that the perturbed conformation of the beta -strand is inconsistent with penicillin binding because of steric clashes between the beta -lactam side chain substituent and the beta -strand. In contrast, no clashes occur upon cephalosporin binding. Recognition of third generation cephalosporins is possible because the bulky side chain substituents of the beta -lactam ring typical of these compounds can be accommodated in the space freed by the deletion of the Omega -loop.

The rivers Figgjo and North Esk are relatively small salmon rivers in southern Norway and eastern Scotland, respectively. Wild salmon smolts have been tagged in these rivers since 1965. Tag returns were used to evaluate the survival of salmon in the North Sea. Survival rates of one-sea-winter (1SW) and 2SW fish were correlated within stocks, as well as between stocks. Survival rates were compared with the areal extent of thermal habitat in the north-eastern Atlantic Ocean. A positive correlation was found between the area of 8-10 degree C water in May and the survival of salmon. A reciprocal negative correlation was also found between survival and 5-7 degree C water in the same month. An analysis of sea surface temperature distributions for periods of good vs. poor salmon survival showed that when cool surface waters dominate the Norwegian coast and North Sea during May, salmon survival has been poor. Conversely, when the 8 degree C isotherm has extended northward along the Norwegian coast during May, survival has been good. The effect of water temperature distributions on the growth of postsmolts and other survival factors are discussed.

Snapshot measurements of grazing damage on randomly collected submersed and floating leaves of Nuphar showed that submersed leaves were more damaged (11.0 plus or minus 1.6%, n = 84) than floating leaves (3.8 plus or minus 0.6%, n = 92). Overall, these 176 Nuphar leaves had 7.2% of their area damaged. 3. Five species of herbivorous insects were commonly found on water lilies (Nymphaeacea). One primarily aquatic insect (sensu Newman, 1991), a caddisfly larva (Trichoptera: Limniphilidae), had a generalized diet of water lilies, other macrophytes, algae, and detritus. Four of the five insects were from primarily terrestrial insect groups (Coleoptera and Diptera; 'secondary invaders', sensu Newman, 1991) and consumed only water lilies in food preference experiments. 4. The feeding preferences of the generalist trichopteran were altered when the macrophytes were freeze-dried, ground into a powder, and reconstituted in an alginate gel. This suggests that plant structure may be an important feeding determinant for this insect. In contrast, a specialist weevil preferred its host plant in choice assays, regardless of whether fresh tissue or reconstituted macrophytes were used, suggesting this insect cued on a unique, non-structural property of its host plant. 5. These results suggest that herbivory on freshwater macrophytes is of a similar magnitude to that on terrestrial plants. The findings of this study are consistent with the hypothesis that herbivorous insects of primarily terrestrial groups have a narrower diet breadth than insects of primarily aquatic groups.

The 19F4 firefighting trainer is an elevated platform or deck with a central region composed of steel grating above propane burners. High winds could push flames below the grating, creating a personnel and equipment hazard. By simulating the trainer with computational fluid dynamics (CFD), scientists from the National Institute of Standards and Technology (NIST) identified the problem - a low-pressure zone below the grating. These dynamics were then used to evaluate the effectiveness of a variety of proposed solutions. The original problem surfaced on the firefighter trainer at the San Francisco Bay Treasure Island naval base. Wind blowing into the bay forced the flames beneath the trainer deck, where they could have damaged instruments and cabling. Wind also stretched the flames into the stairway opening onto the deck. The Navy had tried several experiments to block the wind with steel skirts that rose to deck level around the trainer, but this made the problem worse. Though constructing a building to enclose the trainer was another option considered, this would have been an expensive solution. So the Navy asked for suggestions from the NIST Fire Modeling and Applications Group, which develops and applies mathematical models to fire growth and smoke spread. The group uses three modeling approaches to predict the course of a fire: simple models (back of the "crt"), zone models, and CFD models. The zone model concept is embodied in the CFAST/HAZARD I model, which can predict the time-evolving smoke distribution and fire gases, and the temperature throughout a building during a user-specified fire. HAZARD I combines CFAST with additional capabilities to analyze hazards for various applications.

Although their life cycles are similar, evidence indicates that the species utilize different resources for the primary faunal element of their diets. Prey selection and growth studies have shown that brown shrimp successfully remove infauna from natural sediment. Further, a diet of polychaetes, whether alone or in combination with algae, produced growth in the species. Brown shrimp appear to be trophically linked to infaunal populations, thus the structure and dynamics of the benthic community may directly affect local brown shrimp productivity. Areas dominated by surface-dwelling polychaetes as opposed to deep burrowers may provide more accessible foraging opportunities for juvenile brown shrimp. By contrast, white shrimp neither removed infauna nor grew to a significant degree when provided polychaetes or amphipods as food. White shrimp are omnivorous but do not rely on infaunal material to the same extent as brown shrimp. The primary faunal element in the diet of white shrimp has not yet been identified. The dietary differences between the two species may play a role in determining which species dominates in regions with varying marsh accessibility. Although not the only factors influencing penaeid survival and growth, prey choice and availability may greatly affect production and local success of penaeid populations.

Acetylene reduction (AR) assays were conducted over a 24-mo period to estimate N sub(2) fixation rates on standing dead stems and leaves. In the natural salt marsh, mean AR rates ranged from 0.5 nmol C sub(2)H sub(4) cm super(-2) h super(-1) to 14 nmol C sub(2)H sub(4) cm super(-2) h super(-1), while in the transplanted marsh mean AR rates ranged from 1 nmol C sub(2)H sub(4) cm super(-2) h super(-1) to 33 nmol C sub(2)H sub(4) cm super(-2) h super(-1). Diel AR activity of epiphytic communities in both marshes varied seasonally. Midday incubations yielded higher AR rates than nighttime incubations in the spring, while midday incubations in late summer and fall generally yielded AR rates equal to or lower than nighttime incubations. Desiccation during low tides occasionally repressed AR activity, although AR rates quickly rebounded with wetting. AR activity was localized in the epiphytic community, rather than in the underlying Spartina stem material. Based on the measured AR rates and the density of standing dead stems, the annual input of new N to the natural salt marsh via epiphytic N sub(2) fixation is estimated to be 2.6 g N m super(-2) yr super(-1). The estimate of annual input of new N to the transplanted marsh is 3.8 g N m super(-2) yr super(-1). These estimates should be added to previous estimates of N sub(2) fixation in marsh sediments to estimate the total contribution of new nitrogen to salt marsh nitrogen budgets.

Over the past 100 years, there has been substantial urban and industrial development within this region, resulting in heavy inputs of chemical contaminants at selected sites, as well as significant loss or alteration of marine habitat. Studies show that feral flatfish in Puget Sound are experiencing a range of biological effects due to chemical contaminant exposure, including reproductive dysfunction, altered immune competence, and development of toxicopathic diseases, and there is some evidence of reduced survival in fish from urban areas of Puget Sound from increased infectious and toxicopathic disease. Puget Sound sole are also subject to other anthropogenic stressors, such as fishing pressure or alteration of nearshore nursery habitats. The cumulative impact of these stressors on flatfish abundance in Puget Sound, however, is poorly understood. In a series of field and laboratory studies, we determined vital rates and other life history parameters in English sole (Pleuronectes vetulus) subpopulations from urban and non-urban sites in Puget Sound, and are using this information to estimate potential population level impacts of anthropogenic stressors, with age and stage-based Leslie-matrix models. Initial results suggest that declines in the fecundity component of the model, as observed in field studies of fish from contaminated sites, could reduce the size of sub-populations in these areas if the loss of recruits is not offset by density-dependent changes in recruitment, immigration, or other compensating mechanisms. Studies on flatfish species from a variety of sites in Europe and North America suggest that contaminant-related disease and reproductive impairment are widespread in this group of fish, although substantial differences in sensitivity have been observed, even among closely related species. Comparative studies with a variety of Pleuronectid species will enable us to better evaluate the risk posed by anthropogenic stressors to flatfish, and contribute to improved assessment and management of this important fisheries resource.

N1 - Last updated - 2015-10-28 ER - TY - RPRT T1 - CONSTRUCTION OF THE PALAU COMPACT ROAD, BABELDAOB ISLAND, REPUBLIC OF PALAU (REVISION OF DRAFT ENVIRONMENTAL IMPACT STATEMENT OF MAY 1997). AN - 36406033; 6775 AB - PURPOSE: The construction of a two-lane road system on the island of Babeldaob in the Republic of Palau is proposed. The 127-square-mile island of Babeldaob is the largest island in the Palau archipelago and the second largest island in Micronesia. The island extends in a north-south direction for approximately 28 miles. The southern two-thirds of the island has an average width of eight miles, while the northern third consists of a narrow spur with an average width of one mile. The interior portion of the island is largely uninhabited partly because of limited access via land transportation systems. Existing roads connecting settlements on the island consist of dirt, gravel, or crushed coral surfaces. Three alternatives are considered in this revised draft EIS; the No Action Alternative was eliminated because it would fail to address existing practices and conditions which have a damaging effect on the environment. Under the preferred alternative, a loop system would be constructed in the southern two-thirds of the island and a single spur on the more narrow northern portion. The 53 miles of roadways would connect all ten states on the island and bypass existing settlements instead of running through them. Therefore, the roadway system would need to be complemented by secondary roads connecting to existing settlements. The construction of the roadway would be jointly funded by the U.S. government and the government of Palau. POSITIVE IMPACTS: Under the preferred alternative, the project would provide island-wide access to all settlements while minimizing disturbance to existing communities. The road would also provide access to areas with potential for agriculture, forestry, mining, industry, and tourism, and near watersheds for future water resource development, rock sources for quarries, and port development sites. The road would provide residents of the island an opportunity to live on their land and commute to work in Koror, rather than having to rent additional living quarters at or near Koror, as is now the practice. The project would generate 1,600 jobs per year in construction-related work and 3,088 indirect jobs. NEGATIVE IMPACTS: The economic development expected to result from roadway construction would gradually erode a traditional way of life.

AN - 36403737; 6776 AB - PURPOSE: The designation of Monterey Bay and its adjacent waters, and the submerged lands thereunder, off central California, as a national marine sanctuary is proposed. Under the preferred boundary alternative, the sanctuary would encompass an area of approximately 4,024 square nautical miles in and surrounding Monterey Bay, and would extend along 362 nautical miles of shoreline. Federal and state waters would account for 83 percent and 17 percent, respectively, of the sanctuary. The northern terminus of the sanctuary boundaries would be located along the southern boundary of the Gulf of Farallones National Marine Sanctuary and run westward to approximately the 500 fathom isobath. The boundary line would then extend southward in an arc, following the 500 fathom isobath to a point due west of Cambria. The boundary line would then extend shoreward toward the mean high-water line. The landward boundary would be defined by the mean high-water line between the Gulf of Farallones National Marine Sanctuary and Cambria, exclusive of a 71-square-mile area off the north coast of San Mateo County and the city and county of San Francisco, between Point San Pedro and Point Bonita. Under the preferred alternative, new regulations would be promulgated to govern hydrocarbon activities, discharges and deposits, overflights by low-flying aircraft, the alteration of or construction on the seabed, historical resources, personal watercraft, and marine mammals, turtles, and seabirds. To aid in the enforcement of these regulations, additional regulations would prohibit the possession of resources and the interference with enforcement efforts. These regulations would allow limited, small-scale collection of loose jade found in the Jave Cove area, a series of small coves located south of Big Sur, near Gorda, California. This final supplement to the final EIS of June 1992 considers the environmental effects of this exception. POSITIVE IMPACTS: The designation of the Monterey Bay area as a national marine sanctuary would provide for an integrated program of resource protection, research, and education. Resource protection would involve cooperation with other agencies to assure appropriate implementation of policies and procedures. Through education, public awareness of the value of this area would be enhanced. Sanctuary management would result in the maintenance or improvement of the water quality, fishery resources, and aesthetics of the area. The collection of loose jade, a popular tourist activity, would be allowed to continue under the proposed exception. NEGATIVE IMPACTS: Permit, license, and lease costs would affect local users of the sanctuary. Regulations covering discharges and deposits could result in more substantial cost increases for users. Revenue associated with oil, gas, and mineral activities, all of which would be prohibited under the management plan, would be foregone.

This relationship is further reconfirmed by the 14 C measurements from large volume samples taken in the deep waters in the Pacific Ocean during the recent WOCE survey program. Analysis of upper ocean 14 C measurements made along 152 degree W, and north of 20 degree N, in the northeastern Pacific Ocean during the NOAA's CGC91 cruise, which is a part of the WOCE survey program, indicates that the bomb 14 C inventory in this part of the ocean has increased by 22% since the GEOSECS measurements made in 1974. This increase is consistent with the model prediction of 25% for the Northern Hemisphere ocean. Change of the surface water bomb Delta 14 C values during this period is insignificant. This feature is also consistent with the model simulation. Results of this new analysis will provide useful information of the temporal variations of bomb 14 C inventory in the ocean, in addition to the spatial distribution, which can be used as powerful constraints in calibrating the global ocean carbon cycle models, especially those based on three-dimensional ocean general circulation models, for estimating the uptake of CO 2 by the ocean.

Although these techniques provide excellent performance for masses up to about 20,000 daltons, there has been limited success in achieving good mass resolution at higher masses. This is because the sensitivity of the microchannel plate (MCP) detectors used in most systems decreases rapidly with increasing particle mass, limiting the utility of MCP detectors for very large masses. It has recently been proposed that cryogenic particle detectors may provide a solution to these difficulties. Cryogenic detectors measure the thermal energy deposited by the particle impact, and thus have a sensitivity that is largely independent of particle mass. Recent experiments,, have demonstrated the sensitivity of cryogenic particle detectors to single biomolecules, a quantum efficiency several orders of magnitude larger than the MCP detectors, and sensitivity to masses as large as 750,000 daltons. Here we present results demonstrating an order of magnitude better energy resolution than previous measurements, allowing direct determination of particle charge state during acceleration. Although application of these detectors to practical mass spectrometry will require further development of the detectors and cryogenics, these detectors can be used to elucidate the performance-limiting processes that occur in such systems.

AN - 79670428; 9457881 AB - It is demonstrated here that in Escherichia coli, the phosphorylated form of the glucose-specific phosphocarrier protein IIA(Glc) of the phosphoenolpyruvate:sugar phosphotransferase system is an activator of adenylyl cyclase and that unphosphorylated IIA(Glc) has no effect on the basal activity of adenylyl cyclase. To elucidate the specific role of IIA(Glc) phosphorylation in the regulation of adenylyl cyclase activity, both the phosphorylatable histidine (H90) and the interactive histidine (H75) of IIA(Glc) were mutated by site-directed mutagenesis to glutamine and glutamate. Wild-type IIA(Glc) and the H75Q mutant, in which the histidine in position 75 has been replaced by glutamine, were phosphorylated by the phosphohistidine-containing phosphocarrier protein (HPr-P) and were equally potent activators of adenylyl cyclase. Neither the H90Q nor the H90E mutant of IIA(Glc) was phosphorylated by HPr-P, and both failed to activate adenylyl cyclase. Furthermore, replacement of H75 by glutamate inhibited the appearance of a steady-state level of phosphorylation of H90 of this mutant protein by HPr-P, yet the H75E mutant of IIA(Glc) was a partial activator of adenylyl cyclase. The H75E H90A double mutant, which cannot be phosphorylated, did not activate adenylyl cyclase. This suggests that the H75E mutant was transiently phosphorylated by HPr-P but the steady-state level of the phosphorylated form of the mutant protein was decreased due to the repulsive forces of the negatively charged glutamate at position 75 in the catalytic pocket. These results are discussed in the context of the proximity of H75 and H90 in the IIA(Glc) structure and the disposition of the negative charge in the modeled glutamate mutants.

Pac. CO (sub 2) system data set ( nearly equal 2500 water samples) has been evaluated to assess the internal consistency of measurements and calculations involving CO (sub 2) fugacity and pH (sub T) . This assessment represents the first large scale field comparison of pH (sub T) and f (sub CO2) data. Comparisons of direct discrete CO (sub 2) fugacity (f (sub CO2) ) measurements with CO (sub 2) fugacity calculated from total inorganic carbon (C (sub T) ), total alkalinity (A (sub T) ) and spectrophotometric pH (pH (sub T) = -log[H (super +) ] (sub T) ) indicate that a variety of improvements are needed in the parameter measurements and thermodynamic relationships used to relate f (sub CO2) , C (sub T) , A (sub T) and pH (sub T) in seawater. CO (sub 2) fugacity calculated from C (sub T) and pH (sub T) or A (sub T) and pH (sub T) agree with direct measurements to no better than 1%. Comparisons of measured fugacity, f (sub CO2) (measured), and CO (sub 2) fugacity calculated from C (sub T) and pH (sub T) , f (sub CO2) (C (sub T) , pH (sub T) ), indicate that the precision of f (sub CO2) calculations is good relative to direct measurements. In contrast, due to the extreme sensitivity of f (sub CO2) and [H (super +) ] (sub T) calculations to relatively small errors in both C (sub T) and A (sub T) , CO (sub 2) fugacity, as well as [H (super +) ] (sub T) , calculated from C (sub T) and A (sub T) are very imprecise and render comparisons with direct measurements of little use. Consequently, precise calculations of f (sub CO2) require the use of direct pH (sub T) measurements.

Thus it can be used to determine dissolution of calcium carbonate (hard tissue) and remineralization of organic material (soft tissue), to quantify saturation constants of calcite and aragonite in seawater, and to characterize water masses. f (sub CO2) (20) is a good tracer of biological transformation since it is thermodynamically related to the other inorganic carbon system parameters and it has a dynamic range from 200 to 2000 mu atm in the world's ocean. Precision of f (sub CO2) measurements is 0.3% and the values are well calibrated using compressed gas reference standards. Increases of f (sub CO2) (20) are observed as the water masses age during movement from the Atlantic to the Indian and South Pacific oceans. As an example of the determination of the ratio of soft tissue remineralization to hard tissue dissolution from f (sub CO2) (20) and DIC, the trends along the 27.2 isopycnal for the subtropical gyres of the three basins are investigated. Little CaCO (sub 3) dissolves along this isopycnal in the Atlantic and the South Pacific while the soft tissue remineralization to hard tissue dissolution ratio in Indian Ocean is 4.5:1. The difference in this ratio along the 27.2 isopycnal appears to be a combination of the calcite and aragonite saturation levels and the supply of aragonite tests.

Aircraft cloud samples were taken not only by traditional two-dimensional probes but also by using a new video sampler to account for small particles. The cloud parameter comparisons were made for time intervals when aircraft were passing approximately above ground-based instruments that were pointed vertically. Comparing characteristic particle sizes expressed in terms of median mass diameters of equal-volume spheres yielded a relative standard deviation of about 30%. The corresponding standard deviation for the cloud ice water content comparisons was about 55%. Such an agreement is considered good given uncertainties of both direct and remote approaches and several orders of magnitude in natural variability of ice cloud parameters. Values of reflectivity measured by the radar and calculated from aircraft samples also showed a reasonable agreement; however, calculated reflectivities averaged approximately 2 dB smaller than those measured. The possible reasons for this small bias are discussed. Ground-based and aircraft-derived particle characteristic sizes are compared to those available from published satellite measurements of this parameter for the cirrus priority case from FIRE-II. Finally, simultaneous and collocated, ground-based measurements of visible (0.523 nm) and longwave IR (10-11.4 km) ice cloud extinction optical thickness obtained during the 1995 Arizona Program are also compared. These comparisons, performed for different cloud conditions, revealed a relative standard deviation of less than 20%; however, no systematic excess of visible extinction over IR extinction was observed in the considered experimental events.

This observation by a recent WHO report further stated that in the U.S. alone, there are between 3.3 and 12.3 million cases, and up to 3,900 deaths each year. Microbiological hazards have often become perceived as controllable, and erroneously accepted as familiar old adversaries tamed by modern technology and magic bullets. The consumer and food producer may sometimes give perfunctory attention to sanitary practices, until specific outbreak incidents occur, with highly focused media coverage. Ironically the relatively recent success at reducing diseases from microorganisms has lulled us to complacency about the simplest sanitary measures that have contributed so significantly to their initial control. Although the final critical control point for many food borne diseases is dependent upon the food handling care and knowledge within the final preparation area. Maintenance of sanitary hygienic standards is a serious responsibility for everyone in the food production process. The final regulation Part 123.11 (a) recommends that each processor should have and implement a written sanitation standard operating procedure (SSOP) or similar document that is specific to each location where fish and fishery products are produced. The SSOP places a responsibility on the processor for identifying relevant sanitary controls on conditions that can introduce food safety hazards or cause adulteration of the product. The processor must also maintain sanitation control records that, at minimum, document the monitoring and corrections prescribed in the rule. Additionally as aquaculturists, sanitary practices and hygienic measures are also the baseline defense for avoiding, seducing, or controlling microbiological pathogens in the environment or populations of animals. As mundane as such basic principles like isolate, clean, disinfect, and control access of animal stock, materials and visitors, may be, they remain at the heart of the animal health program that will control the most likely disease causing hazards for either human or animal health.

Data for the years 1948- 1994 was compiled using the NCEP Version III Grid Point Data Set. Patterns were examined during the time of heaviest snow, and composites made of 5 distinct flow patterns. The five flow patterns composited were: Southwest Flow, Amplified Southwest Flow, West Flow, Northwest Flow, and Closed Low. Conposites were obtained by using the GEMCD program. Fields chosen for the composites were: 500 mb heights, Mean Sea-Level Pressure (MSLP), and 250 mb winds. To isolate the heavier snowfalls, separate composites were performed for single day totals of 5-9 inches. Single day snows of 10+ inches were rare, so they were examined individually.

N1 - Last updated - 2015-03-24 ER - TY - JOUR T1 - Secular Trends of Precipitation Amount, Frequency, and Intensity in the United States AN - 17253313; 4542071 AB - Twentieth century trends of precipitation are examined by a variety of methods to more fully describe how precipitation has changed or varied. Since 1910, precipitation has increased by about 10% across the contiguous United States. The increase in precipitation is reflected primarily in the heavy and extreme daily precipitation events. For example, over half (53%) of the total increase of precipitation is due to positive trends in the upper 10 percentiles of the precipitation distribution. These trends are highly significant, both practically and statistically. The increase has arisen for two reasons. First, an increase in the frequency of days with precipitation ]6 days (100 yr) super(-1) [has occurred for all categories of precipitation amount. Second, for the extremely heavy precipitation events, an increase in the intensity of the events is also significantly contributing (about half) to the precipitation increase. As a result, there is a significant trend in much of the United States of the highest daily year-month precipitation amount, but with no systematic national trend of the median precipitation amount. These data suggest that the precipitation regimes in the United States are changing disproportionately across the precipitation distribution. The proportion of total precipitation derived from extreme and heavy events is increasing relative to more moderate events. These changes have an impact on the area of the United States affected by a much above-normal (upper 10 percentile) proportion of precipitation derived from very heavy precipitation events, for example, daily precipitation events exceeding 50.8 mm (2 in.).

In response to this petition and the more general concerns for the status of Pacific salmon throughout the region, NMFS announced that it would initiate ESA status reviews for all species and populations of anadromous salmonids in the states of Washington, Idaho, Oregon, and California. Subsequently, NMFS received a petition (ONRC and Nawa 1995) to list all chinook salmon south of British Columbia under the ESA. The ESA allows the listing of 'distinct population segments' of vertebrates as well as named species and subspecies. The policy of the NMFS on this issue for anadromous Pacific salmonids is that a poulation will be considered 'distinct' for purposes of the ESA if it represents an evolutionarily signfiicant unit (ESU) of the species as a whole.

N1 - Last updated - 2015-03-24 ER - TY - JOUR T1 - How habitat degradation through fishery disturbance enhances impacts of hypoxia on oyster reefs AN - 16522140; 4364457 AB - Oysters are ecosystem engineers that create biogenic reef habitat important to estuarine biodiversity, benthic-pelagic coupling, and fishery production. Prevailing explanations for the dramatic decline of eastern oysters (Crassostrea virginica) during the last century overlook ecosystem complexity by ignoring interactions among multiple environmental disturbances. To explain oyster loss, we tested whether (1) mortality of oysters on natural oyster reefs varies with water depth (3 m vs. 6 m), (2) harvesting by oyster dredges reduces the height of oyster reefs, and (3) bottom-water hypoxia/anoxia and reduction in reef height through fishery disturbance interact to enhance mortality of oysters in the Neuse River estuary, North Carolina, USA. The percentage of oysters found dead (mean plus or minus 1 SD) during a survey of natural reefs in May 1993 was significantly greater at 6-m (92 plus or minus 10%) than at 3-m (28 plus or minus 9%) water depth. Less than one season's worth of oyster dredging reduced the height of restored oyster reefs by similar to 30%. During stratification of the water column in summer, oxygen depletion near the seafloor at 6 m caused mass mortality of oysters, other invertebrates, and fishes on short, deep experimental reefs, while oysters and other reef associates elevated into the surface layer by sufficient reef height or by location in shallow water survived. Highly mobile blue crabs (Callinectes sapidus) abandoned burrows located in hypoxic/anoxic bottom waters but remained alive in shallow water. Our results indicate that interaction of reef habitat degradation (height reduction) through fishery disturbance and extended bottom-water hypoxia/anoxia caused the pattern of oyster mortality observed on natural reefs and influences the abundance and distribution of fish and invertebrate species that utilize this temperate reef habitat. Interactions among environmental disturbances imply a need for the integrative approaches of ecosystem management to restore and sustain estuarine habitat.

Feeding regimes yielding the highest conversion efficiencies of algal feed to molluscan growth are required to maximize the return on algal-culture investments. In the past we have used 12 specialized, manually-controlled molluscan rearing chambers to study nutritional requirements and growth of oysters, clams, and scallops. A computer-controlled, solenoid-valve system was added to automate seawater flow, volume of microalgal food delivered, and feeding duration independently for each chamber. Labor was reduced from 7 h per week to 3 h, while adding flexibility. Each chamber represents a model for a programmed nursery system. Evidence that superior growth of bivalves can be achieved by feeding regimes made possible by this apparatus are provided by an experiment with juvenile bay scallops (Argopecten irradians).

The taxonomic composition and size of prey found in the stomachs of age-0 juveniles collected at three nearshore locations in the Gulf of Alaska in September 1990 were compared to the composition and size of zooplankton collected in concurrent plankton tows. The maximum length of prey consumed increased dramatically over the length range of pollock examined (58-110 mm) from approximately 7 mm to 30 mm, due mainly to the consumption of large euphausiids and chaetognaths by the bigger individuals. The maximum width of prey changed little over this size range although there was a general increase in prey width with increasing predator size. The minimum prey length and width did not change with increasing fish size. Juvenile pollock generally selected the larger prey sizes relative to what was available. Juvenile pollock showed a marked preference for adult euphausiids and decapod larvae and an avoidance of copepods and chaetognaths relative to the numbers collected in net tows. These results are discussed relative to the feeding ecology of these juvenile fishes.

Therefore, other lesions occurring early in the histogenesis of hepatic neoplasia need to be considered as biomarkers of chemical contaminant exposure effects in monitoring studies, especially where adult fish are not available. Moreover, exposure effects may be more reliably assessed in younger fish that have not yet migrated extensively. Accordingly, livers of subadult English sole were histologically examined from nine sites in Puget Sound, WA and the same fish were assessed for contaminant exposure by measurement of fluorescent aromatic compounds (FACs) in bile, hepatic levels of polychlorinated biphenyls (PCBs) and cytochrome P4501A (CYP1A) as catalytic activity of aryl hydrocarbon hydroxylase (AHH), and hydrophobic DNA adducts in liver by super(32)P-postlabelling. Although neoplasms were rare, higher prevalences of preneoplastic, regenerative, and unique degenerative/necrotic lesions were detected in sole from contaminated sites. Prevalences of these early histopathologic biomarkers were significantly higher at the more contaminated sites, and concentration of mean biliary FACs at each capture site was a significant risk factor for most lesions, as determined by stepwise logistic regression. By this statistical method, we also demonstrated that several measures of bioaccumulation or biochemical response to contaminants were significant and near-significant risk factors for prevalences of most hepatic lesion categories. For example, mean hepatic AHH activity was a significant risk factor for prevalence of all lesion types, except neoplasms; hepatic PCB and xenobiotic-DNA adduct concentrations were significant risk factors for the most frequently detected lesion category, hepatocellular nuclear pleomorphism/megalocytic hepatosis, and the inclusive category 'any early toxicopathic lesion'. These findings further support the utility of certain non-neoplastic liver lesions as early indicators of biological damage in subadult as well as adult fish exposed to xenobiotics in the marine environment.

The Standardized Precipitation Index (SPI) was recently developed to quantify a precipitation deficit for different time scales. It was designed to be an indicator of drought that recognizes the importance of time scales in the analysis of water availability and water use. This study compares historical time series of the PDI with time series of the corresponding SPI through spectral analysis. Results show that the spectral characteristics of the PDI vary from site to site throughout the U.S., while those of the SPI do not vary from site to site.

After 96-h exposures, malathion was most toxic to newly hatched larvae with an LC 50 of 9.06 mu g/l followed by an LC 50 of 13.24 mu g/l for 18-day-old larvae and an LC 50 of 38.19 mu g/l for adult shrimp. In a separate bioassay, to simulate field conditions, newly hatched larvae were exposed to malathion at 6 h/day every 5 days at a salinity of 10ppt until metamorphosis to postlarvae. After four pulse dose exposures, mortality was highest in the two highest concentrations, of 15.0 and 30.0 mu g/l. The number of instars to postlarvae was significantly lower in the highest concentration compared to control. The findings indicate that malathion may not directly affect growth in a measurable way but may alter natural metamorphic rhythms at the highest concentrations. Whole body acetylcholinesterase (AChE) activity was measured on Day 0 and Day 15 from the pulse exposure test. AChE activities were not significantly different from controls. Other factors than just AChE inhibition may have contributed to malathion toxicity.

AN - 36401458; 6750 AB - PURPOSE: The consolidation of National Marine Fisheries Service (NMFS) research and administrative facilities, located in Juneau, Alaska, is proposed. The NMFS operates numerous programs and facilities in various locations throughout Alaska. The two largest NMFS programs in the Juneau area are the NMFS Alaska Regional Office (ARO) and the Auke Bay Laboratory (ABL), which is associated with the Alaska Fisheries Science Center in Seattle, Washington. The two facilities, which are located in different parts of Juneau, collaborate in the development of fishery management policies and regulations for the fisheries off the Alaska coast. The ARO is located in rented General Services Administration office space in the federal building in downtown Juneau. The ABL, which provides the scientific research needed to support fishery management decisions, is located on a 3.5-acre site located 12 miles northwest of Juneau. Five alternatives, including a No Action Alternative, are considered in this final EIS. The preferred alternative would involve constructing a facility on a 22-acre site at Lena Point that is currently operating as a rock quarry owned and operated by SECON, Inc. According to the terms of a land trade under consideration, the NMFS would receive the Lena Point site and would transfer its Auke Cape property to Juneau, which in turn would transfer another quarry site to SECON. Access to the site would be provided by Point Lena Loop Road and Towers Road. The facility would include approximately 88,000 gross square feet (gsf) of administrative office space and common areas, 58,000 gsf of laboratory space, and 3,800 gsf of warehouse space. The site would be built to accommodate 273 employees and visitors. The project would include an option to incorporate the University of Alaska Fairbanks School of Fisheries and Ocean Sciences in the facility if there were funding of design and construction. POSITIVE IMPACTS: The consolidation of the two facilities would improve the overall efficiency of program operations and reduce administrative costs. NEGATIVE IMPACTS: The construction of the project would adversely affect homes located along the Point Lena Loop Road. Increased traffic along the road would increase noise levels and alter the community character.

AN - 36406026; 6736 AB - PURPOSE: The construction of a 74,500 square-foot marine environmental health research laboratory in the city of Charleston, located in southeastern South Carolina, is proposed. The facility would support collaborative scientific research by scientists from the National Ocean Service of the National Oceanic and Atmospheric Administration, the National Institute of Science and Technology, South Carolina's Department of Natural Resources, and two nearby academic institutions. The facility would be constructed on eight acres on Fort Johnson on the northeast point of James Island, across Charleston Harbor from the city of Charleston. The preferred site would be located on the south side of Johnson Road, just to the east of the existing laboratory, which was constructed in 1978. The existing facility cannot support the high-technology science applications necessary for current research. Five alternatives for Phase I and three for Phase II, both including a No Action Alternative, are considered in this draft EIS. Phase I of the project would involve the construction of a laboratory designed to accommodate 90 scientists. Phase II would involve the construction of a 8,250-square-foot dormitory, a dining facility, and visiting scientist housing. The housing units would consist of five 1,250-square foot townhouses. The units would be self-contained and independent of other facilities. POSITIVE IMPACTS: The construction of the facility would enable scientists to conduct state-of-the-art stock assessments of critical fish populations, characterize the physical and chemical environment, monitor changes in ecosystems and community structures, monitor the health impacts on organisms of natural and anthropogenic changes, and evaluate the effectiveness of fishery management tools. NEGATIVE IMPACTS: The project would adversely affect wetland and cultural resources. The construction activity would result in increased flow and suspended sediments that would adversely affect surface water quality.

In the Pacific, leatherback populations are in severe decline and recovery actions must be given the highest riority. Primary threats to the species are incidental take in coastal and high seas fisheries, and the killing of nesting females and collecting of eggs at the nesting beaches. The United States does not have any nesting of leatherbacks in its jurisdiction in the Pacific, but has important foraging areas on the continental U.S. west coast and near the Hawaiian Islands. It is likely that stocks in U.S. water originate in Mexico and Central America, though some may originate from Southeast Asia as well. While not directly classified as a threat, the lack of information on the movement patterns and habitat needs of this entirely pelage species (leatherbacks are the only species which remains pelagic throughout its life) is severely hampering recovery efforts and must be addressed as a high priority. The recovery goal is to delist the species.

This latter classification was based on the extensive over-harvesting of olive ridleys in Mexico, which caused a serve population decline. Since the ban on the harvest of turtles in Mexico, the primary threat to the Mexican nesting population as been reduced and the population appears to be stabilizing. Downlisting to Threatened status may be feasible. The primary threats to the olive ridley appear to be indicental take in fisheries and boat collisions while in U.S. waters (or by U.S.-based fishing fleets), and the harvest of turtles and eggs on Mexican and Central American nesting beaches.

AN - 69199482; 10223627 AB - A bloom of the pennate diatom Pseudo-nitzschia, several species of which are associated with the production of the potent excitotoxin domoic acid, was observed in a Puget Sound, Washington embayment in July and August of 1997. Penn Cove, which receives nutrients from the nearby Skagit River and abundant sunshine during summer months due to its location in the rain shadow of the Olympic Mountains, is the home of a commercial mussel farm which supplies shellfish to many coastal areas of the USA. Levels of domoic acid in mussels increased to 3 ppm on 6 and 10 July, corresponding to the observation of a brown algal bloom in Penn Cove. Four species of Pseudo-nitzschia (P. pungens, P. multiseries, P. australis, and P. pseudodelicatissima) were present in our samples from the cove, corresponding to levels of domoic acid in seawater ranging from 0.1-0.8 mirog l(-1) as measured by a receptor binding assay. The highest Pseudo-nitzschia concentration during the time of our sampling was 13 million cells per liter on 28 July. The bloom of Pseudo-nitzschia occurred after a period of strong discharge from the Skagit River and rain accompanied by elevated south and southeasterly winds. Stratification of the cove, providing optimal bloom conditions, was facilitated by weak winds, sunshine, and a freshwater lens at the mouth of the cove. The position of the Pseudo-nitzschia bloom was influenced by buoyancy fronts caused by exchange of water within the cove with that of Saratoga Passage. The decay of this bloom in Penn Cove was accompanied by decreasing nitrate levels at all measured depths. These and future observations aid in the development of a model for prediction of toxic bloom events in the shallow embayments of Puget Sound.

Interviewer-administered questionnaires are specialized forms of conversation, but this framework is less fitting for self-administered questionnaires; eg, self-administered questionnaires maintain the structure of conversational turn taking, but violate the sequential nature of these turns, as respondents have access to future "exchanges." Also, reading introduces additional cognitive processes that affect question answering. Cognitive tests on a series of self-administered questionnaires from the US Decennial Census are used to examine the applicability of the conversational metaphor to the self-administered questionnaire. Questionnaires completed by low-literate populations suggest that reading skills & specific familiarity with questionnaire formats & conventions are necessary for successful completion of a self-administered questionnaire. Other respondents use familiarity with administrative documents to make sense of questions; thus, prior knowledge & expectation play an important role in response. Together, these skills & prior expectations are called "forms literacy." Literacy & prior expectation have important consequences for the pretesting of questionnaires, in terms of (1) choice of respondents in cognitive testing; (2) the practice of reading aloud during cognitive interviewing, & (3) analysis of respondent errors.

Today, the US fertility rate is near or below replacement level, & the baby-boom generation is moving beyond childbearing age. Therefore, future growth in the population will occur primarily through immigration & through births to immigrants & their descendants. Census projections indicate that the proportion of children under age 18 who are white non-Hispanic will decline steadily & rapidly, from about 69% in 1990 to only 50% in 2030. Conversely, the proportion of children who are Hispanic, black, Asian, or of another nonwhite race is expected to expand from 30% to 50%. Data from the 1910, 1960, & 1990 decennial censuses are used to analyze historical changes experienced by first-, second-, & later-generation children regarding (1) parental presence in the home, (2) number of siblings in the home, (3) parental literacy & educational attainments, (4) paternal & maternal labor force participation including part- & full-time work, (5) poverty & income inequality, & (6) overcrowded housing conditions. Analyses are also conducted for first- & second-generation children of changes in their countries of origin, language, parental language, citizenship, & state of residence. Children most at risk of harmful consequences are identified, & the role of race & ethnicity in influencing resources available to children & their future prospects is evaluated.

County-level population estimates are analyzed using a spatial accounting framework to consider variations by region & county economic profile, the relative strength of increased inmigration & decreased outmigration, & the role of manufacturing trends. Among the conclusions drawn is that population deconcentration has been general & geographically well-distributed despite a temporary reversal in the 1980s. Many types of rural counties have experienced reduced outmigration & increased inmigration, due in part to people's economic ability to exercise their preference for smaller places of residence. However, only about 20% of the US population lives outside of metropolitan areas, & the rural rebound of the 1990s appears to be highly sensitive to metropolitan & global economic processes. 4 Tables, 5 Figures, 31 References.

The primary data set came from a chain of eight, three-component magnetometer stations that was operated along a north-south line in central Australia. Additional records, necessary for boundary conditions, were added to the data set. A regional spherical harmonic analysis (SHA) allowed the separation of the internal and external field contributions to the Sq variations. Mapping of the equivalent ionospheric current from the external field showed that the Sq contour focus passed near the -30 degrees geomagnetic latitude of central Australia with a 5 degrees latitude variation between winter and summer and a corresponding change from about 80 to 200 kA in strength. A special transfer function allowed the computation of an equivalent conductivity-depth profile of central Australia from the paired external and internal coefficients of the SHA. A regression line through the conductivity estimates gives a profile that starts at 0.025 S/m for a depth of 130 km, rising gradually to about 0.045 S/m at 250 km, then steepens to 0.11 S/m at 360 km and rises moderately to 0.13 S/m at 470 km near the base of the upper mantle. No data were obtained through the mantle transition zone. Computations gave 0.18 S/m in the region of 800 km depth. Previous conductivity models for the upper mantle beneath central Australia, although less specific in values, are consistent with our profile. At depths greater than 500 km, the regression profile is in agreement with the conductivity distribution beneath the Tasman Sea determined from seafloor magnetotellurics, although both measurements lack high resolution at such depths.

This method greatly reduces the computational effort required to apply MINQUE, thus making it practical to compute variance factors for some very large systems of equations. The computer implementation of the method is described and applied to the computation of variance factors for a combination of 1609 VLBI (Very Long Baseline Interferometry) observing sessions. The purpose of this test was to compute a variance factor for each of the data sets and, perhaps, to obtain more realistic variance estimates to replace those in common use for the analysis of VLBI data. It was found that the method is satisfactory for use with such large problems, and the test served to verify that the variances in current use in VLBI data adjustments are adequate.

The evaluations support the following suggestions: (a) The mean annual runoff of all models follows, at least generally, the strong climatic East-West gradient of precipitation, although most models predict too much runoff in the dry part of the basin. (b) The mean monthly storage change tends to be underestimated, even though all models capture reasonably well the seasonality of the evapotranspiration. (c) The wide range of conceptualizations used for generation of surface and subsurface runoff strongly affect runoff generation on seasonal, and shorter, time scales. Model responses to summer precipitation ranged from almost no summer runoff (one model) to the (more common) situation of persistent overprediction of summer runoff, especially in the driest part of the basin. (d) All models tended to underpredict evapotranspiration in summer and overpredict in winter. (e) Model-derived mean seasonal cycles of changes in soil moisture storage are qualitatively similar to those inferred from observations, but most models do not predict the decrease in April soil moisture storage and the increase in October that is inferred from observations.

Comparisons of simulated surface energy fluxes among models showed that the net radiation and surface temperature generally had the best agreement among the schemes. On an average (annual and monthly) basis, the estimated latent heat fluxes agreed (to within approximate estimation errors) with the latent heat fluxes derived from a radiosonde-based atmospheric budget method for slightly more than half of the schemes. The sensible heat fluxes had larger differences among the schemes than did the latent heat fluxes, and the model-simulated ground heat fluxes had large variations among the schemes. The spatial patterns of the model-computed net radiation and surface temperature were generally similar among the schemes, and appear reasonable and consistent with observations of related variables, such as surface air temperature. The spatial mean patterns of latent and sensible heat fluxes were less similar than for net radiation, and the spatial patterns of the ground heat flux vary greatly among the 16 schemes. Generally, there is less similarity among the models in the temporal (interannual) variability of surface fluxes and temperature than there is in the mean fields, even for schemes with similar mean fields.

Forcing data (precipitation, incoming radiation and surface meteorology) and land-surface characteristics (soil and vegetation parameters) were provided to each of the participating schemes. Two groups of runs are presented. (1) Calibration-validation runs, using data from six small catchments distributed across the modeling domain. These runs were designed to test the ability of the schemes to transfer information about model parameters to other catchments and to the computational grid boxes. (2) Base-runs, using data for 1979-1988, designed to evaluate the ability of the schemes to reproduce measured energy and water fluxes over multiple seasonal cycles across a climatically diverse, continental-scale basin. All schemes completed the base-runs but five schemes chose not to calibrate. Observational data (from 1980-1986) including daily river flows and monthly basin total evaporation estimated through an atmospheric budget analysis, were used to evaluate model performance. In general, the results are consistent with earlier PILPS experiments in terms of differences among models in predicted water and energy fluxes. The mean annual net radiation varied between 80 and 105 W m (super -2) (excluding one model). The mean annual Bowen ratio varied from 0.52 to 1.73 (also excluding one model) as compared to the data-estimated value of 0.92. The run-off ratios varied from a low of 0.02 to a high of 0.41, as compared to an observed value of 0.15. In general, those schemes that did not calibrate performed worse, not only on the validation catchments, but also at the scale of the entire modeling domain. This suggests that further PILPS experiments on the value of calibration need to be carried out.

This interest in Great Lakes research was evident before the turn of the century under the leadership of Prof. Jacob E. Reighard. Early research was primarily concerned with fish and fisheries. The emphasis on fisheries started to shift to basic limnological research after the 1920s when Prof. Paul S. Welch started a limnology course and wrote his book Limnology. His student, Prof. David C. Chandler, returned to the University in 1953 to chair the Council of the Great Lakes Research Institute, and subsequently became the Director of the Great Lakes Research Division in 1960. The emphasis was and has been on basic and applied research involving a broad spectrum of disciplines. The published contributions include biology, chemistry, geology, meteorology, paleolimnology, physical limnology, pollution, radiolimnology, and integrated studies. Among the University's many contributions to furthering Great Lakes research was the origination of the Conferences on Great Lakes Research, started in 1953. Publications of the Proceedings of these conferences provided a valuable reference to research in the 1950s and 1960s. These conferences led to the formation of the International Association for Great Lakes Research and subsequently the Journal of Great Lakes Research. The University acquired several research vessels. The earliest large vessel acquired was the Inland Seas (1960) which was replaced by the Laurentian in 1974. A research submersible was brought into Lake Michigan for evaluation by the Great Lakes Research Division in 1966. At about this time Michigan Sea Grant Program was started in 1969 and the Coastal Zone Laboratory in the 1970s. More recently the Cooperative Institute for Limnology and Ecosystem Research was created in 1989 as a partnership among the University, Michigan State University, and the Great Lakes Environmental Research Laboratory of the National Oceanic and Atmospheric Administration. Much of the Great Lakes research activity at the University was realigned into several colleges and schools in the late 1980s. Great Lakes research at the University has passed through a number of reorganizations, and now exists as the Aquatic Research Programs of the University of Michigan Biological Station.

AN - 52513005; 1999-016008 AB - This study investigated the composition of particulate matter in a series of sediment traps set in the offshore waters of southeastern Lake Michigan. April to October 1982. Of particular interest was the role of zooplankton fecal pellets in rapidly transporting matter from the euphotic zone to lake sediments. Particulate flux was examined microscopically. Dry weight and settling velocities were then estimated based on literature conversion factors and predictive equations. There was an excellent correspondence between estimated flux and direct measurements of flux. Flux was dominated by biological particles of autochthonous origin: fecal matter, fecal pellets, organic aggregates, phytoplankton, and zooplankton exoskeletons. Particles were small with slow (generally <10 m/day) settling velocities. Flux varied seasonally, being highest in spring and autumn, during vertical mixing, and lowest in mid-summer, during strong thermal stratification. High trapping rates during isothermal conditions previously have been associated with resuspension. However, free minerals were a relatively small component of flux. This suggests that isothermal events are associated with the resuspension of previously-settled mineral particles with these particles and slowly-settling biological particles being kept in suspension until the onset of thermal stratification. Because zooplankton fecal pellets and fecal matter are subject to significant degradation and reingestion during the days to weeks that are required for them to reach the lake floor, these egestion products may play a greater role in the recycling of matter in the water column than in the direct transport of matter to the sediments. During summer, when the abundant zooplankton population is food-limited and cladocerans, which produce diffuse egestion products are numerous, relatively little of materials produced in the epilimnion settles immediately to the lake floor.

These samples were analyzed for tissue levels of 16 chlorinated organic compounds, mostly pesticides, as well as for lipid levels. Aldrin, endrin, and lindane were found above detection levels at less than one-half of the sites, primarily at sites in Lake Michigan. Mirex was detected at nine sites mostly in Lake Ontario and the Niagara River, but also near Detroit and in Saginaw Bay. Heptachlor was detected at only two sites, both in Lake Erie. Cis-chlordane, dieldrin, hexachlorobenzene, heptachlor, trans-nonachlor, and total DDTs were detected at all or almost all of the sites. Except for hexachlorobenzene, which was highest near Buffalo, these chemicals were found at higher concentrations in Lake Michigan, especially near Milwaukee, than in the other areas studied. A comparison of the concentrations of chlorinated organic compounds to the levels of lipids showed that differences in dreissenid lipid levels among sites were not the major cause of the observed differences in concentrations in the chlorinated organic compounds. At most sampling locations, the category total DDTs was composed primarily of the DDT breakdown products DDD and especially DDE. However, a substantial percentage of the total DDTs detected at sites in eastern Lake Erie and western Lake Ontario was composed of the parent DDT compounds, suggesting the presence of a relatively recent input of this compound in this area. Comparison of the concentrations of chlorinated organic compounds measured in Great Lakes dreissenids with concentrations of these compounds in marine mussels and oysters found generally similar levels for most of the compounds.

Microfaunal characteristics and population fluctuations can be temporally related to forces of natural (hurricanes, precipitation) and anthropogenic (historic practices from the South Florida Water Management District (SFWMD)) origin since the turn of the century. Dramatic shifts in community structure are observed in both microfaunal groups and are represented by major swings in species' diversity, dominance, and the total loss of numerous species. Before the 1960's, significant crashes in the community structure of both groups were temporally correlated with major hurricanes, but fairly rapid recoveries indicate a relatively resilient community. Community changes during the 1970s were more systematic, and temporally correlate with changes in SFWMD policy. In Whitewater Bay, the 1970's monthly water allocation plan corresponds to a "boom period" for ostracods and benthic foraminifera possibly due to more efficient flow and water exchange. This is followed by a dramatic crash in both groups corresponding to the start of the Rainfall Plan of water management and the closing of the Bottomwood Canal in the early 1980's, from which neither community has recovered. Both cores show a reduction in the number of species and a pronounced dominance of survivor-type species since that time. Oxygen isotope data from ostracods and benthic foraminifers shift to heavier values during this period, indicating drought conditions. Microfaunal and isotope data from this study support the prediction of hydrologic simulation models that the current water management plan has resulted in significantly drier conditions in the lower portion of Shark River Slough and probably deteriorated water quality in Whitewater Bay.

S. High Plains. Severe as this drought was, it resulted in relatively little land-cover change and was likely modest in comparison to mid-Holocene droughts. The paleoenvironmental record indicates that the central North American mid-Holocene droughts resulted in extreme land cover changes and widespread sand dune mobilization. Two climate conditions could explain these findings: less precipitation relative to the 20th century and/or more persistent aridity events. We used the CENTURY grassland ecosystem model and results from the NASA-GISS atmospheric climate model (AGCM) 2' simulation of 6K climate to investigate the effects of modern and mid-Holocene droughts on High Plains eolian deposit vegetation. We ran CENTURY simulations for Alliance, NE, using 1) 1900-1989 observed monthly climate data, 2) 1900-1934 observed monthly climate data followed by perpetual 1934 conditions for 86 years, 3) 1900-1934 observed monthly climate data followed by perpetual 1934 temperature conditions for 86 years and monthly precipitation decreasing 10% annually from 1934, 4) 1900-1989 observed monthly climate data minus the AGCM simulated 6K anomalies, 5) observed monthly climate data from 1900-1934 followed by perpetual 1934 conditions for 86 years with the AGCM simulated 6K anomalies applied to all the data. CENTURY simulation #1 showed decreased above-ground and below-ground biomass during the 1930s but biomass remained high enough to prevent dune mobilization. In simulation #2, although biomass did decrease after 1934, the vegetation cover remained sufficient to prevent dune mobilization. In simulation #3 biomass reductions were large enough after 20 years to permit dune mobilization. CENTURY grassland simulations #4 and #5 are on-going, and will be discussed in the context of the results from simulations #1 through #3. It is likely that droughts of the mid-Holocene were more severe and persistent than those of the 20th century.

The model simulations were run at 4 degrees latitudeX5 degrees longitude (46X72 grid boxes) with nine vertical layers in the atmosphere. The modern controls experiments were run using 1985 A.D. forcing, whereas 6K forcing (e.g. orbital changes, fixed SSTs, trace gases) was imposed as specified by the Paleoclimate Modeling Intercomparison Project (PMIP). All simulations were run for twelve years, and results were averaged for the final ten years. Simulated synoptic atmospheric circulation patterns for the two paleoclimate simulations will be contrasted and then compared both to 1) inferred patterns from geologic evidence for enhanced aridity over the Great Plain at 6K, and 2) the spring to early summer synoptic climatology associated with modern High Plains drought (persistence of a high pressure anomaly in central North America flanked by low pressure anomalies along the east and west coasts, northward displacement of the jet stream and storm tracks, and generally weakened transient eddy activity across the continent; Trenberth and Guillemot, 1996, Journal of Climate 9, 1288-1298). The 6K paleoclimate simulated with Model 2' shows improvement in not only matching many of the features observed in the geologic record for 6K climate relative to the Model 2 simulation, but exhibiting synoptic atmospheric circulation patterns consistent with extensive mid-Holocene drought across the Great Plains.

Independent evaluations of the Cariaco Basin calendar and (super 14) C chronologies were based on the agreement of varve ages with the GISP2 ice core layer chronology for similar high-resolution paleoclimate records, in addition to (super 14) C age agreement with terrestrial (super 14) C dates, even during large climatic changes. These assessments indicate that the Cariaco Basin (super 14) C reservoir age remained stable throughout the Younger Dryas and late Allerod climatic events and that the varve and (super 14) C chronologies provide an accurate alternative to existing calibrations based on coral U/Th dates. The Cariaco Basin calibration generally agrees with coral-derived calibrations but is more continuous and resolves century-scale details of (super 14) C change not seen in the coral records. (super 14) C plateaus can be identified at 9.6, 11.4, and 11.7 (super 14) C ka BP, in addition to a large, sloping "plateau" during the Younger Dryas ( approximately 10 to 11 (super 14) C ka BP). Accounting for features such as these is crucial to determining the relative timing and rates of change during abrupt global climate changes of the last deglaciation.

The work was stimulated, in part, by an atmospheric particle "sample of opportunity" collected at Summit, Greenland in August 1994, that bore the (super 14) C imprint of biomass burning. During the summer field seasons of 1995 and 1996, we collected air filter, surface snow and snowpit samples to investigate chemical and isotopic evidence of combustion particles that had been transported from distant fires. Among the chemical tracers employed for source identification are organic acids, potassium and ammonium ions, and elemental and organic components of carbonaceous particles. Ion chromatography, performed by members of the Climate Change Research Center (University of New Hampshire), has been especially valuable in indicating periods at Summit that were likely to have been affected by the long range transport of biomass burning aerosol. Univariate and multivariate patterns of the ion concentrations in the snow and ice pinpointed surface and snowpit samples for the direct analysis of particulate (soot) carbon and carbon isotopes. The research at NIST is focusing on graphitic and polycyclic aromatic carbon, which serve as almost certain indicators of fire, and measurements of carbon isotopes, especially (super 14) C, to distinguish fossil and biomass combustion sources. Complementing the chemical and isotopic record, are direct "visual" (satellite imagery) records and less direct backtrajectory records, to indicate geographic source regions and transport paths. In this paper we illustrate the unique way in which the synthesis of the chemical, isotopic, satellite and trajectory data enhances our ability to develop the recent history of the formation and transport of soot deposited in the polar snow and ice.

On the practical side, the answer to this question impacts the best achievable precision in well-controlled counting experiments. There have been some noteworthy experimental tests of the Poisson assumption, using systems carefully designed for the analysis of individual pulses from stable radioactive sources; thus far, experiment supports theory. For low-level counting, the nature of the background distribution can be of profound practical importance, especially for very long counting experiments where validation by an adequate number of full replicates may be impracticable. One is tempted in such cases to assume that the variance is equal to the mean, in order to estimate the measurement uncertainty. Background radiation, however, has multiple components, only some of which are governed by the laws of radioactive decay. A specially designed low-level gas counting system at NIST for interactive, retrospective individual pulse shape and time series analysis makes possible the investigation of the empirical distribution function of the background radiation, in a manner similar to the previous empirical distribution studies of radioactive decay. Benefits of individual pulse analysis are that there is no information loss due to averaging and that two independent tests of the Poisson hypothesis can be performed using data from a single, extended measurement period without the need for replication; namely, tests of the distribution of arrival times, expected to be uniform, and the distribution of inter-arrival times, expected to be exponential. For low-level counting the second test has a very interesting and very informative complement: the distribution of coincidence-anticoincidence inter-arrival times. Key outcomes from the study were that: 1) nonstationarity in the mean background rate over extended periods of time could be compensated by an on-line paired counter technique, which is far preferable to the questionable practice of using an "error-multiplier" that presumes the wandering (nonstationary) background to be random; and 2) individual empirical pulse distributions differed from the ideal GM and Poisson processes by exhibiting giant pulses, a continuum of small pulses, afterpulses, and in certain circumstances bursts of pulses and transient relaxation processes. The afterpulses constituted ca. 8% of the anti-coincidence background events, yet they escaped detection by the conventional distributional tests.

Some of these particles result from combustion processes and have undergone long-range transport to arrive in the Arctic. Recent research has focused on the separation of particulate matter from ice and snow, as well as the subsequent analysis of the separated particles for (super 14) C with accelerator mass spectrometry (AMS) and for individual particle compositions with laser microprobe mass analysis (LAMMA). The very low particulate concentrations in Arctic samples make these measurements a challenge. The first task is to separate the particles from the ice core. Two major options exist to accomplish this separation. One option is to melt the ice and then filter the meltwater. A second option is to sublimate the ice core directly, depositing the particles onto a surface. This work demonstrates that greater control is obtained through sublimation. A suite of analytical methods has been used for the measurement of the carbon in snow and ice. Total carbon was analyzed with a carbon/nitrogen/hydrogen (CHN) analyzer. AMS was used for the determination of carbon isotopes. Since source identification of the carbonaceous particles is of primary importance here, the use of LAMMA was incorporated to link individual particle molecular-structural patterns to the same group of particles that were measured by the other techniques. Prior to this study, neither AMS nor LAMMA had been applied to particles contained in snow. This paper discusses the development and limitations of the methodology required to make these measurements.

During 1994 and 1995 we sampled planktonic larval distributions and hydrography both south and north of Point Reyes during upwelling to test whether high concentrations of crab and rockfish larvae were concentrated in the source of the relaxation flow to the south of Point Reyes. An upwelling plume off Point Reyes and an "upwelling shadow", indicated by warmer, less saline water in the northern Gulf, were evident in both years, as were frontal regions that marked the boundaries between water types of three different types: (1) newly upwelled, (2) oceanic, and (3) San Francisco Bay outflow. In addition, there was a fourth type, termed Gulf water, that was a mixture of these three types. Concentrations of larvae of cancrid, pinnotherid, and "coastal" crabs and rockfishes were high south of Point Reyes but were low or absent in the newly upwelled water north of the point. Within the upwelling shadow, these meroplankton taxa were associated with different water masses. Several intertidal crab species and early-stage cancrid crabs were concentrated in San Francisco Bay outflow water, and coastal Gulf water late-stage cancrid crabs, early- and late-stage pinnotherid crabs, and rockfishes were concentrated at the frontal region between newly upwelled and Gulf water. Of the taxa examined, only rockfishes were found offshore in oceanic water. The high concentrations of meroplankton observed suggest that the Gulf of the Farallones is an important area for larvae that settle into coastal populations in the Gulf and to the north via poleward transport during upwelling relaxation.

C-band radar backscatter signatures of various ice types and open water were measured from U.S. Coast Guard Ice Breaker vessels together with ground truth data. Polarimetric backscatter data were obtained at incident angles up to 60 degrees for all polarizations. Backscatter signatures of 20 ice types/conditions were collected along the Coast Guard ship tracks in February and March 1997. The backscatter data set with in-situ ice characteristic parameter measurements are to be used in the development of the ice mapping algorithms using satellite SAR data over the Great Lakes. The results at C-band frequency for multiple incident angles and multiple polarizations are applicable to the current ERS and RADARSAT Synthetic Aperture Radars (SAR) and the future ENVISAT SAR.

Over land the SSM/I measurements at 19, 37 and 85 GHz are used to routinely identify precipitation, snow cover and the surface wetness resulting from rainfall and snow melt. In the case of snow, the measurements vary as function of snow water equivalent, grain size and snow density. Ice crusts at the surface and within the snow can also affect the measurements. As such, the SSM/I measurements depend on the internal properties of snow as well as the snow extent. Studies based on radiative transfer simulations are used to examine the effects of the various snow parameters on the microwave measurements. Temporal variations of the SSM/I measurements are compared with snow data over the former Soviet Union. It is evident that both temporal and spectral information is needed to identify changes in the physical characteristics of snow.

The National Oceanic and Atmospheric Administration Coastal Services Center works with local partners to compile hazards data that specifically address coastal management issues. The goal of these projects is to build upon methodologies being developed nationally for local hazards risk and vulnerability assessments. These projects utilize the newest spatial data technologies, including hurricane storm surge models, LIDAR beach mapping, and products derived from remotely sensed imagery. These CD-ROM products provide different user levels with multiple ways to access the data: a web-browser for viewing static maps, policy descriptions, and hazards analysis; ArcExplorer (super R) for users without geographic information system software; and an ArcView (super R) project file. A CD-ROM has been completed in a cooperative project with the State of Alabama Coastal Zone Program and the South Alabama Regional Planning Commission.

At five other sites, back-scatter anomalies were less distinct, and at the remaining sites, anomalies were absent. These are the first documented hydrothermal sites along this intermediate-rate spreading center and are among the very few yet discovered in the Indian Ocean basin. Some profiles exhibit complex back-scatter anomalies suggestive of multiple sources of seafloor discharge. At one site, near-bottom temperature anomalies of approximately 0.1 degrees C and the recovery of a vent-specific barnacle provide the first precise seafloor location of active venting in the deep Indian Ocean. Although this study is only reconnaissance in nature, venting along this portion of the SEIR appears to be significantly less than predicted by global correlations of plume incidence as a function of spreading rate. Nevertheless, these sites may be important as biological connections between distinct faunal assemblages of Atlantic and Pacific vent fields. Copyright 1998 by the American Geophysical Union.

These are the first ridge-flank hydrothermal springs discovered on crust older than 1 Ma. The springs are venting altered seawater at 25.0 degrees C along a fault near the summit of Baby Bare outcrop, a high point along a ridge-axis-parallel basement ridge that is otherwise buried by turbidite sediment. Baby Bare is a small volcano that probably erupted off-axis ca. 1.7 Ma; it is thermally extinct, but acts as a high-permeability conduit for venting of basement fluids. The springs have been sampled from the manned submersible Alvin. Compared with the ambient ocean bottom water, they are heavily depleted in Mg, alkalinity, CO (sub 2) , sulfate, K, Li, U, O (sub 2) , nitrate, and phosphate, and enriched in Ca, chlorinity, ammonia, Fe, Mn, H (sub 2) S, H (sub 2) , CH (sub 4) , (super 222) Rn, and (super 226) Ra. The springs appear to support a community of thysirid clams. Although we saw no obvious bacterial mats, the surficial sediments contain the highest biomass concentrations ever measured in the deep sea, based on their phospholipid phosphate content. Areal integration of Alvin heat-flow and pore-water velocity data yields flux estimates of 4-13 L/s and 2-3 MW for the total (diffuse and focused) hydrothermal output from Baby Bare, comparable to that from a black smoker vent on the ridge axis. Warm springs such as those on Baby Bare may be important for global geochemical fluxes.

A Report of the Turtle Expert Working Group AN - 19464910; 8016544 AB - At the behest of NMFS, the SEFSC established the Turtle Expert Working Group (TEWG) in February 1995. The charge of the TWEG was first identified in the Endangered Species Act-Section 7 Consultation Biological Opinion for Shrimp Trawling in the southeastern United States under the Sea Turtle Conservation Regulations issued in November 1995. Specifically, NMFS was required to 'select a team of population biologists, sea turtle scientists, and life history specialists to compile and examine formation on the status of sea turtle species. The team should attempt to identify (1) the maximum number of individual sea turtles of each species that can be taken incidentally to commercial fishing activities without preventing the recovery of the species, (2) the maximum number of individuals that can be taken incidently to commercial fishing activities without jeopardizing the continued existence of any listed sea turtle species, and (3) the number of stranded sea turtles occurring in statistical zone that indicate incidental takes are occurring at levels beyond those authorized.' Since the first meeting in June, 1995, there have been 3 subsequent formal meetings which have culminated in the two stock level reports that constitute this publication. There is embodied in this publication a status report for the loggerhead turtle, Caretta caretta, within the southeast U.S. and the Kemp's ridely, Lepidochelys kempii, which is found in both Mexican and U.S. waters. This effort which represents the beginning of an evaluation of the status and condition of these stocks is considered preliminary and exploratory. The authors consider these efforts a work in progress. The TEWG is continuing in it's initial endeavors to develop methods to proceed with stock assessments for turtles and the authors are optimistic that this will be realized. it is the TEWG's desire that the results published in this report be interpreted with caution and within the bounds of the assumptions both with the data and with the methodologies applies. The authors wish to note that the exploratory modelling for the Kemp's ridley was completed only in the context of attempting to understand the life history of this species and to extract population level parameters which duplicate empirical data and numerical trends in abundance. This effort is considered a first step in exploring the use of stage or age specific models to assess the status of sea turtles and particularly progress towards recovery.

Part 1: Background and Information Needs AN - 17966197; 5905971 AB - A two day workshop was convened on February 2-3, 1998 in Charleston, SC with 20 invited experts in various areas of sea turtle research. The goal of this workshop was to review current information on sea turtles with respect to health and identify data gaps. The use of a suite of health assessment indicators will provide insight on the health status of sea turtle populations. Since the relationship of health factors of sea turtles is limited, a second workshop was planned. Using a tiered approach, the first workshop the authors identified and reviewed the available, pertinent baseline information and data gaps. The second workshop will focus on developing the framework for the research plan. The workshops will address the use of integrated set of health parameters; specific objectives are: Identify reliable indicators of health in sea turtles; assess advantages and disadvantages; determine new indicators/biomarkers which may be useful; Review existing sea turtle field sampling projects; Identify field projects suitable for inclusion for health assessment sampling; Identify data gaps, particularly environmental characterization; Identify new health assessment sampling sites, including reference site(s); Develop integrated five-year reserach plan, with focus on health assessment and environmental characterization.

Twenty-seven reports were prepared during this period. Histology reports from the Armed Forces Institute of Pathology (AFIP), Washington, D.C., were received for 21 of these animals. Causes of death were suggested by the AFIP through histological examination and gross necropsy findings, for 11 of the 21 animals (52.4%). Preparation of necropsy reports and collection and packaging of tissues by consistent protocols proved to increase the chances of determining the causes of death through histological examination by the AFIP.

Radioecological situations in the coastal zone and in the open area of the south-eastern Baltic were observed. The objective analysis method was used to define the radionuclide VA field structure. The measured and calculated results of VA field comparison in the south-eastern was satisfactory. According to the nuclear hydrophysical model the imitated situation of a 'passive' admixture spreading calculation in the south-eastern Baltic was carried out.

N1 - Last updated - 2015-03-24 ER - TY - JOUR T1 - Effect of the Niagara River Chippawa Grass Island Pool on Water Levels of Lakes Erie, St. Clair, and Michigan-Huron AN - 17357162; 4511083 AB - Because of renewed riparian interest stemming from the high Lake Erie water levels of the mid-1980s and mid-1990s, and the need for a concise summary of previous studies, a review and a new assessment of the impact of the Niagara River's Chippawa Grass Island Pool on Lake Erie water levels was undertaken. Numerous field and modeling studies dating from 1953 through 1988 provide different assessments of the impacts. The impacts reported by the studies range from "no measureable effect" to a 2 to 5 cm Lake Erie water level decrease. The different results are due to different methods and data, and the fact that the impacts are not directly measureable. A new Great Lakes routing model that more accurately reflects the upper Niagara River hydraulics by explicitly considering the management directive of the Chippawa Grass Island Pool is used to estimate the impacts of deviating from the present directive. The long-term impact of a 0.30 m increase or decrease from the current directive's long-term mean pool level on Lakes Erie, St. Clair, and Michigan-Huron levels is 5 cm, 4 cm, and 2 cm and -4 cm, -3 cm, and -2 cm, respectively. The lakes are minimally responsive to short-term changes in pool levels, with 50% of the Lake Erie impact achieved at about 6 months, and full impact achieved at about 2 years. The minimal lake response, the time lag to full impact, and the local problems resulting from directive deviations, make this a less favorable emergency response measure during periods of extreme lake levels than other alternatives.

Criteria are developed to provide an objective means of determining when random swimming can be neglected, potentially reducing the model complexity and field research necessary to adequately address a given scenario. The models investigated indicate that horizontal random swimming does not contribute significantly to the displacement of oceanic larvae relative to their expected positions, but they do not rule out the importance of vertical random swimming. The models also show that horizontal swimming by larger pelagic organisms could easily dominate turbulence in the ocean and may be important to larvae in less turbulent bodies of water such as bays and lakes.

Natural mortality in salmon occurs in two main phases: juvenile stages experience high mortality during freshwater residency and pre-adult salmon experience high mortality in estuarine and ocean environments. Freshwater survivorship is well characterized and tends to be less variable than marine mortality. Sources of marine mortality are poorly known due to a lack of basic knowledge about post-smolt distributions and habits. Coherence patterns among regional and continental stock groups suggest broad scale forcing functions play a more important role in defining recruitment than mortality effects associated with individual rivers. The action of mesoscale regional environment is most prominent during the post-smolt year when survival, maturation, and migration trajectories are being defined. During the early weeks at sea, growth mediated survival defines recruitment patterns. A correlation between sea surface water temperature and survival has been observed for salmon stocks in the Northeast Atlantic suggesting temperature either directly affects growth or modifies post-smolt behavior. Age at first maturity is controlled by environmental as well as genetic factors. The abundance of two seawinter spawners in North America is directly scaled to the size of overwintering thermal habitat in the Northwest Atlantic, which suggests a link between maturation and environment.

While fisheries scientists have investigated the various elements of habitat and how they affect Atlantic salmon growth and survival, these studies typically focus on requisite requirements for a single life history stage. Current advances in our understanding of salmonid populations in lotic systems indicates that ignoring the spatial positioning of different habitats and dispersal capabilities of fish between them may affect estimates of habitat quality and production of juvenile Atlantic salmon. Using the concepts of juxtaposition and interspersion, we hypothesize that discrete functional habitat units (FHU) occur within river systems and that the spatial structure of FHU affects fish production. We present a method to delineate FHU using habitat maps, fish ecology, and spatial habitat characteristics. Utilizing a simulation model, we illustrate how modeling FHU structure of spawning and rearing habitat in a river system can improve our understanding of juvenile Atlantic salmon production dynamics. The FHU concept allows a flexible approach to more comprehensive analyses of the impacts of habitat alterations, seasonal habitat shifts, and spatial ecology of salmonids at various scales.

This work reviews the recent findings of factors influencing the organism with particular focus on interpreting the potential for contaminant stress, with an emphasis on organic contaminants, and the benthic pelagic link for contaminant food web transfer. The review includes examination of the environmental features that limit the distribution and population density. The physiology of Diporeia spp., including energy storage, respiration, and nutrient elimination, are discussed. The toxicokinetics from both aqueous and sediment exposures are reviewed, as well as both the environmental factors that influence the kinetics and the limitations to our knowledge. The interactions of the physiology and toxicokinetics are presented for interpretation of toxic responses and the sensitivity of the organism to selected contaminants. Finally, this review suggests areas where increased information is needed to improve our understanding of Diporeia toxicokinetics and toxicity in the Great Lakes environment.

Sagittae were removed from 200 fish collected from the Mississippi River delta region and 150 collected from off Panama City, Florida, and examined whole at 800X magnification. Daily growth increments were visible in the sagittae of little tunny (2.5-14.0 mm SL) which ranged in age from 2 to 13 d. Growth estimated as the slope of a regression of SL on age, was rapid (1.07 mm d super(-1)).

A growing awareness that the quality of the coastal ecosystems is being adversely impacted by multiple driving forces has accelerated efforts by scientists and program managers to assess, monitor, and mitigate coastal stressors from an ecosystem perspective. The Intergovernmental Oceanographic Commission (IOC) of the United Nations Educational, Scientific, and Cultural Organization (UNESCO) is encouraging coastal nations to establish national programs for assessing and monitoring coastal ecosystems so as to enhance the ability of national and regional management organizations to develop and implement effective remedial programs for improving the quality of degraded ecosystems. This encouragement follows from the significant milestone achieved in June, 1992, with the adoption by a majority of coastal countries of follow-on actions to the UNCED declarations on the ocean for the nations of the globe to: (1) prevent, reduce, and control degradation of the marine environment so as to maintain and improve its life-support and productive capacities; (2) develop and increase the potential of marine living resources to meet human nutritional needs, as well as social, economic, and development goals; and (3) promote the integrated management and sustainable development of coastal areas and the marine environment.

As we learn more about the science of the problem, the sense of controversy about the state of the science has actually increased, sharply so over the past decade. This essay highlights the fundamental aspects of the science underlying global warming. The vital roles of climate models and of climate data in sharpening scientific understanding are featured. Finally, the roles of controversy in the science and the sociology of this problem are addressed, and new insights are offered on the inevitability of future major conflicts and controversies as society begins to deal with the need to either reduce the use of fossil fuels considerably or adapt to substantial changes in Earth's climate.

We consider structures or elements whose design is governed by wind loads and for which wind directionality effects are not significant. We present estimates according to which ASCE 7-95 Standard provisions for wind loads inducing the design strength result in (1) safety levels that are considerably lower for hurricane-prone than for extratropical storm regions, and (2) estimates of mean recurrence intervals of hurricane wind loads inducing the design strength of about 500 y if epistemic uncertainties are neglected, and significantly lower than 500 years otherwise.

The decline resulted largely from over harvest and direct and indirect losses due to environmental modifications, particularly dam construction. Pool-and-weir fish ladders, with submerged orifices, now successfully pass a large percentage of adult fish at each mainstem dam. Some adult passage delays still exist due to an inability of fish to find entrances to fishways, poor site locations of ladder entrances, inadequate or confusing water velocities that fish reject, and/or poor velocity transitions between fishways or channels into the actual ladders. At all facilities, some fish reject the fishways so that cumulative losses also affect overall stock spawning success. Passage facilities to divert downstream juvenile migrants away from irrigation canals and turbines have been less successful even though US$100s of millions have been spent in the past 20 years on constructing and maintaining louvres, drum screens, bar screens, travelling screens and surface collection devices. Lack of detailed understanding of juvenile fish behaviour related to flow appears to be one of the largest impediments to the development of effective fishways. Further, a lack of periodic maintenance of fishways and screens may decrease their effectiveness.

I will explain what these changes were, what they mean, and how they are being implemented in New England, to provide some context for the discussion about the effects of fishing gear on habitat. The Magnuson Act requirements for habitat information before the 1996 amendments were fairly general. The Act required that each fishery management plan (FMP) must "include readily available information regarding the significance of habitat to the fishery and assessment as to the effects which changes to that habitat may have upon the fishery." Fishery management plans needed to include information about habitat and potential threats, but the law called no attention to important habitat areas and did not require any specific measures to protect habitat.

All components of the planktonic food-web were collected from the same water sample (with the exception of crustaceans), counted microscopically, converted to carbon units, and averaged over the euphotic zone. Due to phosphorus load reductions and the impact of non-indigenous mussels in the lower lakes, physical/chemical characteristics of the lower lakes are becoming similar to those in the upper lakes. Spring total phosphorus and euphotic zone depth were relatively similar among all the stations (except western Lake Erie), ranging from 3 to 7 mu g/L and 21 to 26 m, respectively. During the summer, total phosphorus concentrations were more variable, but ranged between 4 to 10 mu g/L at all stations except western Lake Erie. Planktonic biomass was correlated with total phosphorus concentration. Within a season, the structure of the planktonic food-web was remarkably similar among all stations across all the lakes. Of the seventeen food-web structure parameters examined, only two exhibited significant differences among stations during the spring isothermal period; only four parameters exhibited significant differences among stations during the summer.

Individual crabs were placed in a circular tank that was divided into 4 equal sections containing natural marine sediment (control) and tailings in alternate sections. A time-lapse video camera recorded the position of each crab within the tank over 24 h. Crabs spent significantly (t = 2.43, P < 0.02, df = 24) more time on control sediment (61%) than on tailings (39%). Of 25 test crabs, 19 spent the most time ( greater than or equal to 12 h) on control sediment, whereas only 6 crabs spent the most time on tailings. Ovigerous Tanner crabs may avoid areas affected by the submarine disposal of tailings during the life of the mine. Location of potential submarine tailings disposal sites in areas with high natural sedimentation may accelerate recovery of the sea floor by rapid burial of tailings.

A mortality limit (termed the Potential Biological Removal, PBR, under the U.S. Marine Mammal Protection Act) was calculated as the product of a minimum population estimate (N sub(MIN)), one-half of the maximum net productivity rate (R sub(MAX)), and a recovery factor (F sub(R)). Mortality limits were evaluated based on whether at least 95% of the simulated populations met two criteria: (1) that populations starting at the maximum net productivity level (MNPL) stayed there or above after 20 yr, and (2) that populations starting at 30% of carrying-capacity (K) recovered to at least MNPL after 100 yr. Simulations of populations that experienced mortality equal to the PBR indicated that using approximately the 20th percentile (the lower 60% log-normal confidence limit) of the abundance estimate for N sub(MIN) met the criteria for both cetaceans (assuming R sub(MAX) = 0.04) and pinnipeds (assuming R sub(MAX) = 0.12). Additional simulations that included plausible levels of bias in the available information indicated that using a value of 0.5 for F sub(R) would meet both criteria during these "bias trials." It is concluded that any marine mammal population with an estimate of human-caused mortality that is greater than its PBR has a level of mortality that could lead to the depletion of the population. The simulation methods were also used to show how mortality limits could be calculated to meet conservation goals other than the U.S. goal of maintaining populations above MNPL.

Currently, northern elephant seals breed on thirteen islands and four mainland sites from Isla Cedros in Baja California Sur, Mexico, to Cape Arago, Oregon, USA. Le Boeuf et al. (1996) reported observations of stray juveniles as far away as Amaknak Island in the Aleutian Islands, Midway Island and Hokkaido, Japan. There are no historical records to indicate whether elephant seals occurred in the Gulf of California, prior to 1979, when the first known observation was made. Here, we summarize recent records of northern elephant seals in the Gulf of California with respect to age, gender, and distribution.

The author studied the first step in the predation sequence, reaction to prey, for different zooplankton taxa by lake herring. Reactive distance was significantly shorter for smaller zooplankton taxa (p < 0.0001). Reactive volume was calculated from measured distances and angles of elevation and bearing. This volume augments the reactive distance data and showed a three dimensional geometry, roughly analogous to a deflated basketball, that is amenable to a cruising style of planktivory. Reactive volume is dynamic with respect to variations in prey size (p < 0.001). Reactive volume is a refined measure of a 'reaction' by fish to a prey item than are simple, linear distances or other, assumed shapes. Thus, for a cruising planktivore, three dimensions need to be considered.

Based on biometric changes that are projected to occur, it appears that early control of a non-indigenous fish species, specifically ruffe (Gymnocephalus cernuus), can result in significant investment returns. By instituting a ruffe control program, benefits to the public will exceed costs by 44 to 1 over the next five decades. Under a moderate case projection of benefits this will yield an estimated net public savings of $513 million for the United States. Since sportfishing values are much greater than commercial fishing values, anglers will benefit the most from this program.

The management community, academic researchers, and others, spurred on by a growing body of concerned ocean resource users, have begun to grapple with the notion of ocean governance based on the principles of ecosystem management. Marine protected areas (MPAs) are one key element in this growing era of bigger thinking and in the context of national ocean governance discussions. The inclusion of marine protected areas initiatives in the ocean governance discussions is a positive step toward integrating ecosystem principles within this governance structure, and a number of valuable lessons can be gleaned from taking a look at some of these efforts. This paper focuses on one such program, NOAA's National Marine Sanctuary Program (NMSP), and provides some insights into its evolution and innovative efforts to foster ecosystem management in and around these coastal and ocean areas. This discussion will profile new ideas being formulated by the NMSP which address how MPAs such as these sanctuaries can provide opportunities for catalyzing broader ecosystem management initiatives and how they can serve as laboratories for developing innovative and alternative ocean governance mechanisms. Finally, the paper will examine the critical role of forging effective partnerships to make this essential coordination and collaboration a reality for successful ocean governance.

This "best-available" information involves analysis from a number of experts. The decision-maker must compile these discrete pieces of information to make decisions on protection strategies and priorities. In response situations, it can sometimes be obvious when less-than-optimum decisions have been made, In planning or drill situations, the evaluation of these decisions can be very difficult. This paper proposes a quantitative approach to integrate this information into a "game" that can be played, in a planning phase, to examine alternate scenarios. Game theory is used to design the "game", and linear programming is used to quantify and optimize the results.

The most widely used organizing tool for dealing with natural and environmental resource choices is benefit-cost analysis, which offers a convenient way to carefully identify and array, quantitatively if possible, the major costs, benefits, and consequences of a proposed policy or regulation. However, a major shortfall of benefit-cost analysis has been the difficulty of quantifying both benefits and costs of actions that impact environmental assets not normally or regularly bought and sold in markets. Economists and other social scientists have put a great deal of effort into addressing this shortcoming by developing techniques to quantify these non-market benefits. To make that link, NOAA has undertaken a series of Regional Environmental Valuation Workshops to introduce and illustrate concepts of environmental valuation to state and local coastal planners and managers, fishery managers, and those concerned with the broad range of coastal sustainability issues.

The most widely used refrigerants are among them. Chemical and equipment manufacturers mounted aggressive research and development programs to introduce alternative and transition refrigerants, associated lubricants and desiccants, and redesigned equipment. The already difficult criteria became even more complex, with subsequent linkage of chemical emissions from human activities to global climate change. The very successful response to protect the ozone layer has led some regulators and users to assume that ideal substitutes will be found. Such chemicals should be free of all environmental and safety concerns, be chemically and thermally stable, and perform efficiently. The analyses presented in this paper demonstrate that the outlook for discovery or synthesis of ideal refrigerants is extremely unlikely. Trade-offs among desired objectives, therefore, are necessary to achieve balanced solutions. The paper also shows that fragmented regulation of the chemicals involved, to address individual issues, jeopardizes the prospect of solving subsequently addressed problems. The paper reviews the history of refrigerants, their roles in ozone depletion and global climate change, and necessary trade-offs in refrigerant selections.

Halon emissions persist because of a lack of suitable substitutes for critical uses as fire extinguishants. As of January 1, 1997, halons H-1301 (CBrF sub(3)), H-1211 (CBrClF sub(2)), and H-2402 (CBr sub(2)F sub(4)) were present in the troposphere at 2.3 plus or minus 0.1, 3.5 plus or minus 0.1, and 0.45 plus or minus 0.03 pmol mol super(-1). During 1995-1996 the tropospheric mole fraction of H-1301 increased at 0.044 plus or minus 0.011 pmol mol super(-1) yr super(-1), while that for H-1211 grew at 0.16 plus or minus 0.016 pmol mol super(-1) yr super(-1). These increases are significant and of concern because of the efficiency of bromine in depleting stratospheric ozone and because of the long atmospheric lifetimes of these gases. Given the current atmospheric record and the reported amount of halon produced before the ban on production, emission of H-1301 at the 1995-1996 rate could continue for another 40 years, but H-1211 would be depleted in 8-12 years. Exemptions to the ban on production may extend these periods. Tropospheric H-2402 is increasing at 9 plus or minus 1 fmol mol super(-1) yr super(-1), but historical data on its production and use are lacking. JF - Journal of Geophysical Research. D.

AN - 16292071; 4280832 AB - Releases of hatchery-reared anadromous salmon into the North Pacific Ocean are currently estimated between 5 and 6 billion juveniles per year. Wild spawning salmon may produce an additional 4 to 5 times this number of juveniles. With as many as 25 billion juvenile Pacific salmon (Oncorhynchus spp.) annually entering the ocean and currently producing over 1.0 million mt of returning adults, salmon survival and production in the North Pacific is currently at historically high levels in spite of depressed runs and endangered stocks in some regions. Biological changes in size and age at maturity of some stocks have raised questions on the density effects of high abundance, and on the long-term well being and health of salmon stocks. Changes in size and age notwithstanding, favorable ocean conditions for survival and growth, even growth at reduced levels, have produced historic numbers and biomass of salmon suggesting the evidence for limitations in the carrying capacity for these fishes in inconclusive. Important studies are underway in several countries to better understand the effects of hatchery-wild stock interactions on the spawning grounds but little attention has been directed toward this issue in the ocean. New mass marking and identification technologies for both hatchery and wild fish provide mechanisms for investigating the interactions of salmon in the open ocean. Given biological concerns about ocean carrying capacity and socio-economic issues associated with record runs, should NPAFC member countries consider cooperative quotas to limit production of salmon around the North Pacific Rim?.

Chum salmon spawners returning to Fish Creek, southeastern Alaska, were sampled yearly from 1972 through 1996. Spawners retuning to the Quilcene National Fish Hatchery in Hood Canal, Washington, were sampled yearly from 1973 through 1996. Size at maturity of both populations declined significantly from about 1980 to the mid-1990s. Age at maturity increased during this time. These changes were associated with a major ocean climate regime shift in the North Pacific Ocean that occurred in 1976-77. Population abundance of chum salmon increased greatly after the regime shift, especially in Asia. Similar changes in size and age at maturity occurred in Asian chum salmon; because the range of North American and Asian chum salmon overlaps on the high seas, these changes are discussed in relation to possible density-dependent population factors. Since the mid-1990s, size at maturity and population abundance have increased, possibly indicating another climate change in the North Pacific Ocean.

N1 - Last updated - 2016-05-27 ER - TY - JOUR T1 - Effect of pollution on fish diseases: potential impacts on salmonid populations AN - 13665750; S199952947 AB - Wild Pacific salmonids had disappeared from about 40 per cent of their historical breeding ranges. Their decline was attributed to the cumulative effects of both natural and anthropogenic factors creating adverse environmental conditions. The effects of pollution on the physiological health of juvenile salmon by increasing their susceptibility to disease was investigated. Juvenile fall chinook salmon (Oncorhynchus tshawytscha) from polluted estuaries were found to be immunosuppressed and thus more susceptible to disease than those from less polluted waters. The potential for disease in contaminant-exposed salmonid populations might be increased or reduced by exposure or non-exposure of the fish to pathogens, respectively. Studies had shown that pathogens were a ubiquitous and integral component of most watersheds, suggesting that disease was a natural occurrence regulating fish populations. However, anthropogenically induced factors might significantly shift the balance between salmonid survival and mortality to disease. There are 32 references.

Calculated 96 and 168 h LC50 values for P. pugio were 9542 and 6464 ng PAH per g dry sediment, respectively. Parental male and female copepod survival was unaffected until at 1211 ng PAH per g, female survival was reduced by 24 per cent. Mean clutch size was reduced to 83.7 per cent of control values in 1211 ng PAH per g treatments. Consistent dose:response trends apparent in the number of nauplii and copepodites per surviving female, and the calculated potential effects on reproduction, indicated that PAH possibly affected reproduction at levels which were normally thought to be non-effect levels. Copepod results were in general agreement with other studies. P. pugio was more sensitive to PAH mixtures than A. tenuiremis.

This preliminary study indicated that these levels cause abnormalities and raised new concerns about many sites where PCB are present in sediment in high concentrations.

The limits were derived from risk assessments. Criteria for sea disposal of dredged materials specify that sediments are unacceptable for ocean dumping if they fail prescribed toxicity tests or if chemicals of concern are accumulated in the tissues of test organisms in laboratory tests. Much higher levels of chemical contamination are allowed in sewage sludge for land application than in dredged materials for sea disposal. If human exposure to chemicals from dredged material were to be calculated on the basis of reasonable assumptions about how much of a highly exposed human's diet came from sediment-exposed organisms, the dredged material criteria would be much less stringent.

Data were collected from estuaries along the Atlantic, Pacific and Mexico gulf coasts. ERL and TEL were highly predictive of non-toxicity when not exceeded. When exceeded samples were generally highly toxic. Incidences of toxicity increased when mixtures of chemicals were normalized to the SQG. PEL indicated a high prediction ability in samples where substances exceeded the required concentrations. There are 30 references.

The present study utilized immunohistochemical localization and quantitation of CYP1A expression by image analysis, linked with quantitation of hydrophobic DNA adducts by radiolabelled 32-phosphate-postlabelling in neoplasms. A comparison was made to matched samples of adjacent non-neoplastic liver tissue from the same fish. Fish were obtained from the Duwamish waterway in Seattle, Wash., and a significant and nearly parallel reduction in DNA adduct concentrations (56-90 per cent) and CYP1A expression (3-99 per cent) were observed. There was no difference in proportional reductions for either DNA adducts or CYP1A expression between adenomas and carcinomas. The findings were consistent with the hypothesis that neoplastic hepatocytes in P. vetulus possess a 'resistant' phenotype in which there is a reduced capacity for CYP1A-mediated activation of genotoxic PAH to their toxic and carcinogenic intermediates. Factors other than CYP1A expression affecting DNA adduct concentrations in hepatic neoplasms are discussed.

Following 15 minutes sonication in water, 0.01 ml of Nafion (5 g per litre in ethanol) was coated onto the electrode and dried. Nitrate reductase (0.1 units) was then secured behind the dialysis membrane. Methyl viologen absorbed into the Nafion and acted as a reservoir for the electron mediator. Calibration of the electrode indicated a response time to nitrate of less than 1 minute. The upper detection limit for nitrate was 0.012 mol per litre and the lower limit was 3.0 umol per litre. Interference by metals and oxygen at the working potential of minus 0.8 Volts versus silver /silver chloride is discussed. The assay compared favourably with colorimetric and ion-selective electrode techniques and did not require any expensive or complex-associated instrumentation. It could also easily be adapted to field analysis. JF - Analytical Chemistry AU - Glazier, SA AD - National Institute of Standards and Technology, Gaithersburg, Md.

The contaminants included low and high molecular weight PAH, PCB 105 and 118, hexachlorobutadiene, hexachlorobenzene, DDT, heptachlor and several pesticides. There had been no appreciable changes in disease prevalences or apparent contaminant exposure of flatfish since the 1970s. Female flatfish showed evidence of precocious sexual maturation in 40-50 per cent of young animals and inhibited gonadal development was observed in 20-30 per cent of older fish. Two species of juvenile salmon were exposed to levels of contaminants which can impair growth, increase immunosuppression and increase mortality following pathogen exposure. Elevated levels of DNA adducts and CYP1A activities in liver of contaminant-exposed fish were observed. The study provided a scientific and legal basis for cleaning up and restoring this degraded habitat.

The distillation procedure involved mixing the powdered sample (200-250 mg) with sulphuric acid and copper sulphate in a Conway dish. Almost all of the organically bound mercury in the 2 mussel tissues (at least 99 per cent) was present in the form of methylmercury using other techniques. The mean organic mercury concentration for 4 replicate analyses of IAEA-350 was 3.61 ug per g, compared with a certified value of 3.65 ug per g. The mean concentrations for 7 analyses of SRM 2976 and 5 analyses of SRM 2974 were 27.9 ng per g and 78.3 ng per g, respectively. The results for the 2 mussel tissues were in good agreement with those obtained by other investigators using 3 different methods and were used in the assignment of certified methylmercury concentrations for these materials.

The data provided information on the comparative vulnerability of different species in a variety of habitats. Concentrations of aromatic hydrocarbons in the WSF did not deviate more than 2 per cent from target concentrations. LC50 values after 28 d exposure were similar (mean 1.21 mg per litre, standard deviation 0.29) ranging from 0.62-3.8 mg per litre. Arctic species were twice as tolerant as the most temperate species tested. Length of exposure was a major factor contributing to LC50 values. Pink salmon fry responded quickly to oil exposure with similar 4 and 28 d values (1.2 mg per litre). Subtidal animals (flounder, shrimp, king crab and scallops) continued to respond for several days (28 d LC50 were 52-58 per cent lower than 4 d LC50). Intertidal animals (shore crab, starfish, snail and mussel) responded slowly with no deaths within 7 d but with 28 d LC50 values lower than juvenile fish. The most resistant animals were the planktonic amphipods. Subtidal animals were nearly twice as sensitive to 4 d flow-through exposures as to 4 d static exposure whereas intertidal animals were resistant to any 4 d oil exposure. Chronic oil exposure minimized the differences in hydrocarbon sensitivity between species.

Using a gradient-elution LC separation, the retention and dechlorination behaviour of a suite of model amines was determined, representing primary and secondary aliphatic, peptide and protein-nitrogen. Tertiary-treated wastewater showed a fraction of the organic nitrogen-chloramines were dechlorinated slowly by sulphite with half-lives of more than 20 minutes. Chromatographic retention and kinetic behaviour were consistent with the behaviour of the model peptides and proteins. Dechlorination occurred rapidly for the nitrogen-chloramines derived from ammonia, leucine, butylamine and piperidine. Proteolytic hydrolysis markedly increased the 'peptide' fraction observed upon chlorination of the wastewater. Peptides and proteins contributed to the slow dechlorination of sewage and may be factors in the toxicity noted for chlorine-disinfected wastewater.

P. vetulus develops hepatic neoplasms which are virtually absent in P. stellatus. The study examined the hypothesis that variation in the hepatic expression of cytochrome P4501A (CYP1A) may contribute to the different contaminant response. Catalytic activity of CYP1A (determined as aryl hydrocarbon hydroxylase (AHH) activity), measured in liver tissue, was significantly higher in P. vetulus than in P. stellatus. Cellular expression of CYP1A, determined by the immunohisto-chemical localization of tissues, using an avidin-biotin peroxidase complex method, with polyclonal rabbit anti-cod CYP1A, indicated a marked reduction of CYP1A expression in hepatocytes of P. stellatus. This was consistent with the apparent resistance to the development of hepatocellular neoplasia. Hepatocyte staining increased with increasing AHH activity for both species. This was highly significant in P. stellatus but not in P. vetulus. Endothelial cell staining showed no increase with increasing catolytic activity in P. vetulus, or marked decrease with increasing AHH activity in P. stellatus. Both species showed increased endothelial staining with decreased hepatocyte staining. The increased expression of CYP1A in hepatocytes contributed more to whole tissue catalytic activities than did increased expression in endothelial cells. The inverse relationship between endothelial cells and hepatocytes suggested that increased endothelial cell staining was due to increased uptake of toxicants, resulting in decreased exposure of hepatocytes.

The programmes were the U.S. EPA monitoring project of 1965-1972, the U.S. EPA 'Mussel Watch' programme of 1976-1978, the National Oceanic and Atmospheric Administration's Mussel Watch project started in 1986 and the ongoing State of California's Mussel Watch programme begun in 1977. Decreasing and increasing trends were observed for copper on a site-by-site basis and were approximately equal except for California, where increasing trends were found at all 5 study sites. No trends were found for PAH, nickel or zinc concentrations. Trace element usage had decreased for cadmium, lead, nickel, silver and zinc since the 1970s and was reflected by lower levels in mussels.

Less significant decreases existed for copper, zinc and silver. Concentrations of polycyclic aromatic hydrocarbons, arsenic, mercury, nickel, lead and selenium showed no overall trend. Decreases observed for DDT, PCB, dieldrin and aldrin were due to their banned use in the early 1970s. Infrequent detections of tin, lindane, mirex, endrin and hexachlorobenzene were significant in the reduced contaminant trends.

Culture experiments in metal ion-buffered media revealed that toxicity, nutrition and the accumulation of cellular metals was governed by complex competitive interactions among the metals. High levels of ionic copper(II) and zinc(II) inhibited cellular manganese uptake, and high copper(II) inhibited zinc uptake rates. There was an association between these effects and growth rate inhibition at combined conditions of high zinc(II) and low manganese(II) and at high copper(II) and low zinc(II). Zinc inhibited uptake of manganese by competitively binding to a high affinity manganese uptake system. Cellular zinc concentrations increased as external manganese(II) was decreased. The uptake of zinc also involved a high-affinity zinc system which was induced in the presence of low zinc(II) and a separate low-affinity system. Zinc uptake by the high-affinity system was inhibited in the presence of high copper(II) concentrations.

Total densities declined from 16,800 per m2 in 1980-1981 to 4800 per m2 in 1992-1993 at sites in the 16-30 m depth and from 21,300-11,300 per m2 at sites in the 31-50 m depth. At sites deeper than 50 m only sphaeriids declined to any extent. Declines in oligochaetes and sphaeriids occurred uniformly throughout the nearshore region and during the entire sampling period, which was possibly related to reductions in phosphorus loads and a general decrease in productivity. Declines in Diporeia occurred principally in the later part of the sampling period and were greatest in the south-eastern region of the lake. Densities at many sites in the south-eastern region were 3000-8000 per m2 in 1980-1981 and less than 100 per m2 in 1993. There are 45 references.

The total polynuclear aromatic hydrocarbon (TPAH) concentration in tissue, VHSV prevalence and mortality correlated with dose, and histopathologic lesions were significantly correlated to TPAH concentration and the prevalence of VHSV. Lesions included increased hepatocellular necrosis, splenic thrombosis and decreased inflammation in the liver. Concentrations of axenic hydrocarbons were elevated in tissue and multifunction oxidase enzymes were induced. A decreased incidence of hepatic inflammatory cells was evidence for immunosuppression in the exposed fish and the decreased immune surveillance was a possible mechanism by which subclinical VHSV could be reactivated.

Significant differences were observed for antimony, arsenic, cadmium, chromium, copper, lead, mercury, nickel, selenium, silver, tin and zinc. The high level of intersite variability frequently precluded statistically significant intersite differences. Strong correlations were found between the percent fines and concentrations of copper, selenium and zinc in sediment. Element concentrations in fish liver and stomach, plotted against total organic carbon (TOC) content of the sediment indicated that for the non-essential elements arsenic, cadmium, mercury, antimony and silver and the essential elements copper, zinc and selenium, some for the highest liver concentrations were found in fish from reference sites in Washington and California, which generally contained the lowest element concentrations and TOC in sediment. This may have been due to enhanced bioavailability. Generally, concentrations found in stomach contents supported the high liver concentrations. TOC may be correlated with controlling ligands for metals such as acid volatile sulphides or iron and manganese oxyhydroxides.

In this introduction we review the similarities and differences between regional and global atmospheric models. Next, the structure of regional models is described and we consider how the basic algorithms applied in these models influence the parallelization strategy. Finally, we give a brief overview of the eight articles in this issue and discuss some remaining challenges in the area of adapting regional weather models to parallel computers.

Here, we describe a bioreactor where the reducing power to the cycle is supplied directly to purified cytochrome CYP101 (P450cam; EC 1.14.15.1) through its natural redox partner (putidaredoxin) using an antimony-doped tin oxide working electrode. Required oxygen was produced at a Pt counter electrode by water electrolysis. A continuous catalytic cycle was sustained for more than 5 h and 2,600 enzyme turnovers. The maximum product formation rate was 36 nmol of 5-exo-hydroxycamphor/nmol of CYP101 per min.

TheM. tuberculosis adenylyl cyclase gene (cya) was cloned by complementation of a cAMP dependent expression of maltose operon in acya deletionE. coli strain. The nucleotide sequence analysis of thecya gene revealed an open reading frame that coded for 443 amino acids. A comparison ofM. tuberculosis adenylyl cyclase with the protein sequences in the data bank revealed its homology to the eukaryotic Type I and the calmodulin responsive adenylyl cyclases with an average of about 40% identical and 60% similar amino acids in the catalytic domain. The occurrence of eukaryotic-like adenylyl cyclase inM. tuberculosis suggests a role for this important enzyme in cell signaling and perhaps in the pathogenesis ofM. tuberculosis. We suggest that the human pathogenM. tuberculosis might have acquired the eukaryoticcya by a recombination event.

The National Weather Service (NWS) has used PE to obtain daily estimates of mean evapotranspiration in continuous rainfall-runoff models for river forecasting. The daily PE estimates are derived mainly from meteorological data gathered on a regular basis throughout the country. Solar radiation is one of the required input variables. Because of its widespread availability, sky cover is now used almost exclusively by NWS to estimate solar radiation. Over a period of time, a bias has developed between the long-term mean PE (computed using a combination of historical observed pan evaporation data and meteorological data) and PE estimated operationally using real-time meteorological data. This difference is a result of the use of sky cover based solar radiation estimates. These biased solar radiation estimates translate into long-term means of PE which are significantly lower than values using corresponding direct measurements of solar radiation or estimates of solar radiation using percent sunshine. A standard for PE has been established and verified to which long-term means can be compared. PE estimates derived from sky cover can be corrected to the standard using a ratio of long-term means. Many meteorological variables which have been measured or observed manually in the past are being converted to automatic observations. With the advent of automated sensors, which do not duplicate the manual sky cover observations, another source of solar radiation is necessary to model PE for use in river forecasting. Satellite estimates of solar radiation are compared with other means of measuring and estimating solar radiation. Available on a nationwide basis, satellite estimates produce values of solar radiation comparable to those obtained by direct measurement. Based on availability and accuracy, satellite estimates of solar radiation are recommended for use in the estimation of PE instead of estimates derived from sky cover or hours of sunshine (percent sunshine). This assumes that no direct observations of solar radiation are available.

The MOST model is capable of simulating three processes of tsunamic evolution, i.e., generation by an earthquake, transoceanic propagation, and inundation of dry land. Generation and propagation capabilities were tested against deep ocean bottom pressure recorder (BPR) data collected by PMEL during the 1996 Andreanov tsunami; inundation computations were compared with field measurements maximum runup on Okushiri Island collected shortly after the 1993 Hokkaido-Nansei-Oki tsunami. Computed estimates agreed well with observations, indicating that the MOST model will be a valuable tool in the development of tsunami forecasting and hazard mitigation tools.

First, we calculated the trends in the seasonal cycle of measured atmospheric CO (sub 2) at observation stations in the National Oceanic and Atmospheric Administration Climate Monitoring and Diagnostic Laboratory network. Second, we assessed the impact of terrestrial ecosystems in various localities on the mean seasonal cycle of CO (sub 2) at observation stations using the Carnegie-Ames-Stanford Approach terrestrial biosphere model and the Goddard Institute for Space Studies (GISS) atmospheric tracer transport model. Third, we used the GISS tracer model to quantify the contribution of terrestrial sources and sinks to trends in the seasonal cycle of atmospheric CO (sub 2) for the period 1961-1990, specifically examining the effects of biomass burning, emissions from fossil fuel combustion, and regional increases in net primary production (NPP). Our analysis supports results from previous studies that indicate a significant positive increase in the amplitude of the seasonal cycle of CO (sub 2) at Arctic and subarctic observation stations. For stations north of 55 degrees N the amplitude increased at a mean rate of 0.66% yr (super -1) from 1981 to 1995. From the analysis of ecosystem impacts on the mean seasonal cycle we find that tundra, boreal forest, and other northern ecosystems are responsible for most of the seasonal variation in CO (sub 2) at stations north of 55 degrees N. The effects of tropical biomass burning on trends in the seasonal cycle are minimal at these stations, probably because of strong vertical convection in equatorial regions. From 1981 to 1990, fossil fuel emissions contributed a trend of 0.20% yr (super -1) to the seasonal cycle amplitude at Mauna Loa and less than 0.10% yr (super -1) at stations north of 55 degrees N. To match the observed amplitude increases at Arctic and subarctic stations with NPP increases, we find that north of 3O degrees N a 1.7 Pg C yr (super -1) terrestrial sink would be required. In contrast, over regions south of 3O degrees N, even large NPP increases and accompanying terrestrial sinks would be insufficient to account for the increase in high-latitude amplitudes.

We studied the impacts of sediment on the coral communities of St. Lucia following a tropical storm. We found more sediment and coral damage on reefs closest to the mouths of large rivers. Coral mortality exceeded 50% at some sites, and the degree of coral mortality and bleaching depended on the amount of sediment at the site. Despite exemplary efforts by engineers to reduce erosion rates, we found more sediment at sites near a road under construction at the time of the storm. Collectively, our data demonstrated a major negative impact of land development on coral reefs, a problem likely to grow in scale given the growing demands for developed land and the recent frequency of large storms in the tropical Atlantic.

However, shoreline bioremediation has several misunderstood limits. Field research indicates that hydrocarbon-degrading microbes occur in all aquatic environments and that they reproduce greatly in the presence of oil: it is useless to add more. Wind, waves, currents, existing oil-degrading bacteria, nutrients, and oxygen are generally sufficient to promote maximum rates of degradation of oil. Under some circumstances, continuous or periodic application of nutrients (fertilizers) over a period of at least several weeks can accelerate oil degradation by factors of 1.5- to perhaps 5-fold. All future work should be done using statistically-robust sampling designs. In Japan, as elsewhere, there is great need for well-controlled, well-replicated, full-scale field tests to find out which, if any, bioremediation methods would be most useful for various oils, fuels and shoreline types.

The majority of the sea turtles reared from neonates at the NMFS Galveston Laboratory have been Kemp's ridley, Lepidochelys kempii, which were part of an international effort to restore this endangered species to its original population status (Klima and McVey, 1982; Mrosovsky, 1983; Caillouet, 1984; Fontaine et al., 1985, 1989, 1990). This aspect of the recovery effort, referred to as the Head Start Experiment, was terminated at the end of the 1992 year-class rearing season upon recommendation by a special review panel (Eckert et al., 1992). Secondarily to the Kemp's ridley, large numbers of loggerhead sea turtle, Caretta caretta, intended to be used in turtle excluder device (TED) certification trials (Watson et al. 1986; Mitchell et al., 1989), have also been reared from neonates in the facility.

National Status and Trends Program for Marine Environmental Quality AN - 17652168; 4466320 AB - The purpose of the study is to: (1) continue monitoring historical trends in the concentration of contaminants in Puget Sound sediments, and (2) quantify recent trends in the recovery of contaminated sediments. Results from this study can be compared with those obtained in the 1982 study to determine whether sediment quality is still improving and to estimate the rate of recovery. A statistically significant reduction in sediment contamination over the past 20 years would provide empirical evidence that environmental regulation has had a positive impact on the water quality in Puget Sound. Chemical trends were evaluated from six age-dated sediment cores collected from the main basin of Puget Sound. Chemical analyses included metals, polynuclear aromatic hydrocarbons (PAHs), PCBs and chlorinated pesticides, nutrients (total nitrogen (N), and phosphorus (P)), butyltins, and total organic carbon (TOC). Sedimentation (cm/yr) and deposition rates (g/sq cm/yr) were estimated using a steayd-state Pb-210 dating technique.

Network analysis was invoked to compare the exchanges of carbon in 3 mid-Atlantic estuaries on the eastern U.S. coast: the Narragansett, Delaware, and Chesapeake Bays. Narragansett Bay exhibited the highest average annual rate of net primary production, followed by Delaware and Chesapeake Bays. Taken in combination, the analyses of cycling structures (magnitude of flows, average carbon cycle lengths), organization of carbon flows, system production:biomass ratios, and harvest rates all indicated that the Delaware and Chesapeake Bay ecosystems are more stressed than that of Narragansett Bay. To differentiate between the former two, a combination of measures of system efficiency, cycling structure, and food web connectivity was employed. The results indicated that Delaware Bay is currently less impacted and has potentially more ability to mitigate perturbations to its food web than does Chesapeake Bay. Overall, network analysis proved to be a suitable methodology for making inter-estuarine ecosystem comparisons, and for providing useful insights to natural resource managers in the assessment of estuarine trophic structure and status.

A battery of water-column and sediment bioassays were employed with animals and plants. The study was conducted in coordination with a fish community sampling program. Tests were conducted monthly from April through August 1994 at five sample sites in each of four tidal tributaries. Mortality, reproduction, and growth rates in the water-column assays did not consistently indicate chemical contamination in any system. Chemical analyses did not indicate elevated levels of contaminants in the water column. Sediment bioassays demonstrated greater responses than water-column assays. Sediment in the upstream reaches of the South River demonstrated significant toxicity. Toxicity was also observed at the uppermost Severn River station and the middle Patuxent River station. Chemical analyses of composite sediment samples indicated elevated metals levels in the South River. Some metals were above threshold values in the Patuxent and Wicomico rivers. The AVS/SEM ratios in pore water were below 1 in all cases. Organic analyses demonstrated low level polycyclic aromatic hydrocarbon contamination in all four systems. The toxicological risk ranking model ranked the South River as the most contaminant-impacted site. The Patuxent and Severn rivers were ranked below the South River; however, the ranking model identified specific locations in the Severn and Patuxent rivers that indicate sediment contamination. The Wicomico River had the lowest overall risk score. The Patuxent River requires more intense sampling due to its relatively larger size. The toxicological risk ranking results for sediment were significantly correlated with species diversity for fish communities sampled by bottom trawl. Results were consistent with data from previous years. Regression analysis of 2 years of data indicate that fish community impairment can be predicted with ambient toxicity results.

Differences between fyke-net catches in the river and seine catches in the river's estuary indicated that many downstream migrants remained in the lower river instead of migrating to sea. In particular, age-0 coho salmon (O. kisutch) and chinook salmon (O. tshawytscha) moved downriver from May to November but were not caught in the estuary. Age-0 sockeye salmon (O. nerka), coho presmolts, and other groups delayed entry into the estuary after moving downriver. We tagged groups of juvenile coho (ages 0-2) from the fyke net with coded-wire to determine when they left the river. One-third of all tags recovered from sport and commercial fisheries occurred 2-3 years later, showing that many coho remained in fresh water for 1-2 years after moving to the lower river. Lower-river areas of large glacial rivers like the Taku River can provide essential rearing habitat for juvenile salmon spawned upriver and are important to consider in integrated whole-river management of transboundary rivers.

The study focused on elevational differences in larger tree species ( greater than or equal to 10 cm DBH = diameter at breast height) on a floodplain bench, floodplain slope, and upland terrace. The three habitat zones showed differences in floral assemblages related to the flooding tolerance of tree species, the floodplain bench showing ash-maple dominance and the other habitats yielding maple-beech-oak dominance. The floral differences were likely attributable to natural and human impacts, particularly stream flooding and possibly past logging. The results and a literature review suggest that hydrologic disturbances (for example, flooding) create predictable, parallel patterns in floral assemblages along a lateral (stream-edge to upland) gradient. Riparian assessments in the lateral dimension can provide information to predict the effects of anthropogenic instream-flow alterations on riparian ecosystems, including small tributaries.

Hydrologic model parameters are inherently tied to the space-time scales at which they were calibrated. The National Weather Service calibrates rainfall runoff models using 6-hour mean areal precipitation (MAP) inputs derived from gage networks. The space-time scale sensitivity of the Sacramento model runoff volume is analyzed using 1-hour, 4 X 4 km super(2) next generation weather radar (NEXRAD) precipitation estimates to derive input MAPs at various space-time scales. Continuous simulations are run for 9 months for time scales of 1, 3, and 6 hours, and spatial scales ranging from 4 X 4 km super(2) up to 256 X 256 km super(2). Results show surface runoff, interflow, and supplemental baseflow runoff components are the most sensitive to the space-time scales analyzed. Water balance components of evapotranspiration and total channel inflow are also sensitive. A preliminary approach for adjusting model parameters to account for spatial and temporal variation in rainfall input is presented.

We examined the proximity of group members to each other in juvenile walleye pollock, Theragra chalcogramma, under different environmental conditions. Food availability, simulated by a gradient of six ration treatments, had a major influence on group cohesion, with increasing dispersion as food level decreased. Group cohesion also decreased at night relative to daytime levels. Small juveniles (x super(-) = 53 mm TL) maintained on high rations were highly responsive to the potential threat of a predator, with groups becoming more cohesive and remaining so for up to an hour after the initial threat. A chronic threat (continual presence of predators) resulted in tighter group cohesion than an acute threat (single simulated attack). Small juveniles maintained on low rations were less responsive to predation threats and recovered quickly, supporting the hypothesis that hunger induces risk-taking behavior. Large juveniles (x super(-) = 149 mm TL) did not change their degree of aggregation in response to either type of predation threat. An overall plasticity in the degree of cohesiveness among group members indicates that walleye pollock are capable of gradually modifying their schooling behavior according to the environmental context.

Evaluation of the model simulations is performed using observations of total soil moisture in the top 1 m, runoff, evaporation, snow depth, and water-table depth made within the catchment. The Valdai study demonstrates that using only routine meteorological measurements, long-term simulations of land-surface schemes suitable for model evaluation can be made. The Valdai dataset is available for use in the evaluation of other land-surface schemes. Both the SSiB and the bucket models reproduce the observed hydrology averaged over the simulation period (1967-83) and its interannual variability reasonably well. However, the models' soil moisture interannual variability is too low during the fall and winter when compared to observations. In addition, some discrepancies in the models' seasonal behavior with respect to observations are seen. The models are able to reproduce extreme hydrological events to some degree, but some inconsistencies in the model mechanisms are seen. The bucket model's soil-moisture variability is limited by its inability to rise above its prescribed field capacity for the case where the observed water table rises into the top 1-m layer of soil, which can lead to erroneous simulations of evaporation and runoff. SSiB's snow depth simulations are generally too low due to high evaporation from the snow surface. SSiB typically produces drainage out of its bottom layer during the summer, which appears inconsistent to the runoff observations of the catchment.

Several of these hypotheses have been grouped under a general, "growth-mortality" hypothesis, which postulates that larger (a "bigger-is-better" mechanism), faster growing (a "growth-rate" mechanism), and faster developing (a "stage-duration" mechanism) individuals have a higher probability of survival. Using the otolith record of age, size, and ontogeny, these three mechanisms of the "growth-mortality" hypothesis were tested for the larval and pelagic juvenile stages of bluefish, Pomatomus saltatrix (Pisces: Pomatomidae), a moderate-sized, coastal, pelagic, marine fish. Individuals that were larger-at-age were found to have a higher probability of survival, supporting the "bigger-is-better" mechanism. Faster growing individuals were also found to have a higher probability of survival, agreeing with the prediction of the "growth-rate" mechanism. Equivocal evidence was found with regard to the "stage-duration" mechanism. These results suggest that in pelagic ecosystems, larger and faster growing larvae have a higher probability of survival. Given the observed directional selection acting on larval size and growth, several potential mechanisms that maintain variable larval size and growth are addressed. Finally, the growth-related processes examined in this study are discussed in the context of the physical aspects of pelagic ecosystems that may also affect larval survival.

The planning of operations during a spill event requires an estimate of the future distribution of the pollutant. These are typically obtained by computational algorithms, database references, numerical modeling, or more generally the techniques of trajectory analysis. Since the results of the trajectory analysis are a critical factor in the formulation of operational decisions, the consequences of uncertainty in the forecasts must be analyzed in terms of the response activities they must support. The uncertainty in the forecast results from trajectory analysis must be evaluated in the broadest possible sense. Beginning with the way to solve hydrodynamic flow equations in a sparse data environment, then proceeding to models of geophysical forcing which are the result of additional forecasting, and thus are also uncertain. Finally the contribution of the trajectory analysis to the chain of decision logic that is actually used to formulate response must be considered. Once the uncertainty associated with trajectory analysis results is understood, a use strategy can be formulated on how best to present and use the information. Operations research and game theory methods suggest that 'minimum regret' strategies provide a powerful and understandable procedure for the delivery of forecast information into the spill response system. A digital standard has been developed for implementing this 'minimum regret' strategic approach and has been operational for nearly three years. During this time the response community has used it on over 100 spills and drills with a high level of acceptance.

Appropriate values for beta and alpha are discussed and applied to current anthropogenic nitrogen fixation rates, which are dominated by synthetic fertilizer and crop production. These calculations yield an N sub(2)O source of about 3.5 Tg N/yr associated with anthropogenic nitrogen fixation, which accounts for most of the observed atmospheric N sub(2)O increase of 3-5 Tg N/yr. This simple nitrogen cycle-based approach toward estimating anthropogenic N sub(2)O sources provides a useful check on the more complex approaches employed today, in which emissions from a large number of small, independent sources are estimated by extrapolating measured emissions coefficients. Such approaches can be inconsistent with considerations of the global nitrogen cycle and likely have underestimated the fertilizer N sub(2)O source and double counted other sources. A box model of atmospheric N sub(2)O which assumes an anthropogenic N sub(2)O source proportional to past and projected future rates of anthropogenic nitrogen fixation can reproduce much of the historic growth in N sub(2)O. Continued growth in the rate of anthropogenic nitrogen fixation could increase atmospheric N sub(2)O to 400 - 500 ppbv by the year 2100. Two-dimensional model calculations suggest that the corresponding increase in stratospheric NO sub(x) would cause a small loss of O sub(3), which would be superimposed upon a larger recovery due to the phaseout of anthropogenic halocarbons. An increase in N sub(2)O could put more NO sub(x) into the middle and upper stratosphere than supersonic aircraft, although the relevant time scale is considerably longer. To better understand the impact of anthropogenic nitrogen on atmospheric N sub(2)O and the stratospheric O sub(3) layer, more information is needed about future anthropogenic nitrogen fixation rates, the N sub(2)O yields of denitrification and nitrification, net storage/loss of naturally and anthropogenically fixed nitrogen, and NO sub(x) chemistry in the stratosphere.

AN - 36413692; 6667 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. An amendment to the FMP is thought to be needed in order to protect five species (red porgy, vermillion snapper, greater amberjack, black sea bass, and gag) from the effects of overfishing. The proposed action as presented in this final supplement to the final EIS of August 1983 would include four provisions to prevent overfishing and protect the habitat of these five species. The provisions would limit snapper grouper permit holders to owners of boats or vessels that can demonstrate any landings of species during 1993-1996 and had a valid permit during the period from February 11, 1996 through February 11, 1997. Those vessels that can demonstrate landings of at least 1,000 pounds in any year during 1993-1996 would receive a transferrable permit. All other vessels would receive a non-transferable permit and would be limited to a 225-pound trip limit. Overfishing would be redefined at 20 percent of the spawning potential ratio (SPR), and optimum yield would be set at 40 percent SPR. One bait net up to 50 feet long and 10 feet high with a stretched mesh size of 1.5 inches or less would be allowed per boat. Vessels would be permitted to possess and use cast nets for catching bait. Species within the snapper grouper management unit caught in Bahamian waters in accordance with Bahamian law may be possessed aboard a vessel in the South Atlantic region and landed in the U.S., provided the vessel is in transit from the Bahamas and valid Bahamian fishing and cruising permits are onboard. POSITIVE IMPACTS: The amendment to the FMP would stabilize and protect the snapper grouper fisheries in the South Atlantic. Limiting permit holders would provide a cap on the number of participants, prevent future increases in fish mortality, and improve data collection and monitoring efforts. NEGATIVE IMPACTS: The decrease in the number of permitted vessels and restrictions on landings would create short-term economic hardships on commercial operators. 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.).

AN - 36405675; 6660 AB - PURPOSE: The development of a business park, partially funded under Title I of the Economic Development Administration's (EDA's) Public Works and Development Facilities Program, located in northeastern Pennsylvania, is proposed. The site, which was selected from 20 candidate sites, is located eight miles northeast of the city of Scranton. The economy of the area has historically relied on coal mining, iron and steel production, and textiles, but since 1945, these industries have been in steady decline. Four alternatives, including a No Action Alternative, are considered in this draft EIS. The business park would provide development sites of various sizes to firms interested in modern manufacturing, distribution, and office facilities. The local applicants (Scranton Lackawanna Industrial Building Company and the Borough of Jessup) would market the park to prospective tenants in an attempt to recruit high-value jobs to the area. The park would be developed on 1,124 acres located northeast of the intersection of Marshwood Road and SR 247, within the Moosic Mountain range, straddling Jessup and Olyhant boroughs. Under the proposed plan, individual industrial facilities would range on size from 50 to 100 acres. The applicants have requested $2.0 million from EDA in order to provide water supply and roadway improvements, while funds from other sources would be used to construct other needed infrastructure improvements. POSITIVE IMPACTS: The park would stimulate growth in an economically distressed area, generating up to $200 million in private investment and supporting up to 5,000 new jobs. NEGATIVE IMPACTS: The development would result in wetlands degradation from increased surface water runoff, sedimentation, and road salt runoff.

This region has been the subject of numerous and often conflicting studies that have attempted to construct the history of plate motion and plate boundary evolution as the Australia and Pacific plates separated from Antarctica. Our novel approach entails reconstructing gravity fields from satellite altimeter gravity by first removing anomalies overlying seafloor younger than a selected age, and then rotating the remaining anomalies through appropriate finite rotations. Our reconstructions reveal: (1) an extensional plate boundary (the Iselin rift) existed between West and East Antarctica prior to A24 time; (2) the arrival of the Southeast Indian ridge (SEIR) at the Tasman ridge (prior to A24) led to the extinction of the Iselin rift as well as the conversion of the easternmost portion of the Tasman plate boundary (between the SEIR and the Iselin rift) into a transform fault on the Pacific-Antarctic ridge; and (3) an early (A24 or younger) inception of the Australia-Pacific plate boundary. Our scenario for the opening of the Southwest Pacific Ocean can explain the present-day gravity anomalies and magnetic isochrons observed in the northwest Ross Sea. We find that the East Antarctic seafloor northeast of the Iselin Bank was generated by spreading on the Tasman ridge prior to A24 time.

(super 186) Os/ (super 188) Os and (super 187) Os/ (super 188) Os ratios are also listed for Noril'sk ores, the carbonaceous chondrite Allende, and Os standard.

(super 190) Pt/ (super 186) Os ratios for six enstatite chondrites average 0.001659 + or - 75 close to those for carbonaceous chondrites; a solar system initial (super 186) Os/ (super 188) Os ratio of 0.119820 is derived. The (super 186) Os/ (super 188) Os ratio of presumably young, mantle-derived Os and the carbonaceous chondrite is 0.119834 + or - 2; (super 186) Os/ (super 188) Os of the Noril'sk plume indicates enrichment in (super 186) Os of 0.012% compared to that of modern upper mantle.

The mission of NFRL is to enhance the competitiveness of U.S. industry and public safety by developing performance prediction methods, measurement technologies, and technical advances needed to assure improvement of the life cycle quality and economy of constructed facilities. BFRL's efforts are closely coordinated with complementary activities of industry, professional and trade organizations, academia, and other agencies of government. The vision for BFRL, the structure of its technical programs, and the determination and timing of its technical products are based on analyses of industry needs and BFRL's own unique resources and capabilities. This report summarizes BFRL's research for 1997. The report is arranged by its research programs: structural engineering, materials engineering, mechanical and environmental systems, fire safety and engineering, fire science, and applied economics.

A 2-year time series of temperature and light attenuation measurements within the water column shows a rapid decay of the maximum rise height of the chronic plumes over the first 3 months following the eruption. We use these measurements to estimate the hydrothermal heat fluxes into the chronic plumes at two different sites. We hypothesize that the chronic plumes resulted from the convective cooling of a dike and construct a simple two-dimensional, numerical model of this process for a vertical dike intruded into a cold, saturated porous layer. The width of the dike and the permeability and thickness of the porous layer control the transfer of heat from the dike to the seafloor. We investigate the effects of these parameters on the temporal evolution of the surficial heat fluxes. The results show that simple convective cooling of the dike can reproduce the observed temporal evolution of the heat fluxes for permeabilities in the range 10 (super -11) -10 (super -12) m (super 2) and a 3- to 5-m-wide dike. The high permeabilities obtained are consistent with flow through highly permeable extrusives or with the creation of a zone of high permeability near the dike walls due to fracturing. The width of the dike may well be overestimated by our model because of the limitations of the continuum approximation for the permeability in the narrow upflow zone adjacent to the dike.

Over 24,000 modeled trajectories are aggregated into distinct patterns using cluster analysis. Ten-day trajectories reaching Summit are longest during winter, with 67% extending upwind (westward) as far back as Asia or Europe. Trajectories are shortest during summer, with 46% having 10-day origins over North America. During all seasons a small percentage (3-7%) of trajectories originate in west Asia/Europe and follow a meridional path over the Arctic Ocean before approaching Summit from the northwest. Trajectories at the 700-hPa level tend to be shorter than at 500 hPa, with many of the 700-hPa trajectories from North America tracking over the North Atlantic and approaching Summit from the south. The long-range transport climatology for Summit is similar to a year-round climatology prepared for Dye 3, located 900 km to the south [Davidson et al., 1993b]. An analysis of several aerosol species measured at Summit during summer 1994 reveals examples of the usefulness and also the limitations of using long-range air trajectories to interpret chemical data.

Mean meridional sections of potential temperature, salinity, neutral density anomaly, and the square of buoyancy frequency are presented for the western, central, and eastern tropical Pacific Ocean. These sections are used together with maps of depth and salinity on isopycnals, as well as thickness between isopycnals, to describe the evolution of the Tsuchiya jets as they flow from west to east. An inertial-jet model is formulated in which conservation of the Bernoulli function and potential vorticity combine with the eastward shoaling of the tropical pycnocline to dictate the jet structure. This model jet is consistent with a number of features of the Tsuchiya jets: their roughly constant volume transports, their advection of properties such as salinity and oxygen over long zonal distances, their rapidity and narrowness, their poleward shift from west to east, the large potential vorticity gradients across them, and the pycnostad between them that builds in size and strength from west to east. However, an observed decrease in density carried by the Tsuchiya jets from west to east, not included in the model jet, suggests that diffusive or advective interaction with the surrounding ocean also may be important in subsurface countercurrent dynamics.)

This new dataset, which the authors have named the CPC Merged Analysis of Precipitation (CMAP), contains precipitation distributions with full global coverage and improved quality compared to the individual data sources. Examinations showed no discontinuity during the 17-yr period, despite the different data sources used for the different subperiods. Comparisons of the CMAP with the merged analysis of Huffman et al. revealed remarkable agreements over the global land areas and over tropical and subtropical oceanic areas, with differences observed over extratropical oceanic areas. The 17-yr CMAP dataset is used to investigate the annual and interannual variability in large-scale precipitation. The mean distribution and the annual cycle in the 17-yr dataset exhibit reasonable agreement with existing long-term means except over the eastern tropical Pacific. The interannual variability associated with the El Nino-Southern Oscillation phenomenon resembles that found in previous studies, but with substantial additional details, particularly over the oceans. With complete global coverage, extended period and improved quality, the 17-yr dataset of the CMAP provides very useful information for climate analysis, numerical model validation, hydrological research, and many other applications. Further work is under way to improve the quality, extend the temporal coverage, and to refine the resolution of the merged analysis.

The predictive approach consists of burning materials using a bench-scale method that simulates realistic fire conditions, measuring the concentrations of the primary fire gases - CO, CO sub(2), low O sub(2), HCN, HCl, HBr, and NO sub(2) - and predicting the toxicity of the smoke using either the 6- or 7-gas N-Gas Model. These models are based on the results of toxicological studies of these primary gases as individual gases and as complex mixtures. The predicted toxic potency is checked with a small number of animal (Fischer 344 male rats) tests to assure that an unanticipated toxic gas is not generated or an unexpected synergistic or antagonistic effect has not occurred. The results indicate if the smoke from a material or product is extremely toxic (based on mass consumed at the predicted toxic level) or unusually toxic (based on the gases deemed responsible). The predictions based on bench-scale laboratory tests have been validated with full-scale room burns of a limited number of materials of widely differing characteristics chosen to challenge the system. The advantages of this new approach are 1. the number of test animals is minimized by predicting the toxic potency from the chemical analysis of the smoke, 2. smoke may be produced under conditions that simulate the fire scenario of concern, 3. fewer tests are needed, thereby reducing the overall cost of the testing and 4. information is obtained on both the toxic potency of the smoke and the responsible gases. The N-Gas Models have been developed into the N-Gas Method (described in this paper) and these results have been used in computations of fire hazard. The 6-Gas Model is now part of the international standard ISO 13344 approved by 16 member countries of the International Standards Organization (ISO) and is also included in the U.S. national standard ASTM E1678 approved by the American Society for Testing and Materials (ASTM). In addition, the 6-Gas Model is used in the American National Standard - NFPA 269 - approved by the National Fire Protection Association (Quincy, MA). The second new research approach, toxicant suppressants, examines the potential of chemical compounds, which when added to a material, to inhibit or reduce the concentration of a specific toxic gas normally generated during the material's thermal decomposition. The effectiveness of this approach was demonstrated at the National Institute of Standards and Technology (NIST) when HCN generation was reduced by 90% and the resultant toxicity of the combustion products was lowered by 50% when a flexible polyurethane foam (FPU) was treated with 0.1% (by weight) cuprous oxide (Cu sub(2)O). Copper and cupric oxide (CuO) also reduced the HCN generation but were not as efficient as Cu sub(2)O. Although melamine-treated FPU foams are being promoted as more fire safe than standard foams, a melamine-treated foam generated 10 times more HCN than a foam without melamine. The addition of Cu sub(2)O to this melamine foam also reduced the HCN generation by 90%.

The NCP requires lead response agenciesto integrate baseline risk assessments into the remedial process that "assess threats to the environment." EPA policy statements direct regional offices to perform thorough, consistent ecological risk assessments, and stress the importance of coordination and technical consultation with the natural resource trustees. As a Federal natural trustee, the National Oceanic and Atmospheric Administration's (NOAA) role and responsibilities within the CERCLA process also are defined and mandated by Federal law. NOAA is responsible for identifying sites in the coastal zone that may affect natural resources, evaluating injury to trust resources, and providing technical advice on assessments and remedial and restoration alternatives. Statutes require lead cleanup agencies and trustee agencies to notify and coordinate with each other during CERCLA response. Over the past ten years, NOAA has gained valuable experience and technical expertise in environmental assessments and in evaluating contaminated aquatic environments. NOAA fulfills its responsibilities through an effective network of Coastal Resource Coordinators (CRCs) who can rapidly respond to local technical requirements and priorities, and coordinate effectively with technical and trustee representatives. In addition to CRCs, an interdisciplinary support group provides technical expertise in the scientific disciplines required to respond to the needs of regional activities. NOAA provides CRCs to coastal EPA regional offices for technical support, and to act as liaisons with Federal and state natural resource trustee agencies. The CRCs help EPA and other lead response agencies identify and assess risks to coastal resources from hazardous waste sites and to develop cost-effective strategies to minimize those risks. Notification of trustees of potential natural resource injuries and coordination of subsequent investigations helps Federal and state trustees to carry out their responsibilities effectively. Trustees' early involvement in the scoping of ecological risk assessment ensures that assessments and the entire remedial process adequately evaluate the risk to trust resources. Coordination throughout the process makes it easier to develop cost-effective and protective remedies that enhance the recovery of natural resources. Examples of NOAA's successful coordination and cooperative ecological risk assessments will be presented in brief case studies for both EPA and Department of Defense (DOD) lead sites.

Water collected from above the salinity intrusion zone of each river was filtered, brought to a salinity of 15 ppt, and inoculated with estuarine bacteria. Bacterial production rates (8 to 26 x 10 super(5) cells ml super(-1) d super(-1)) during the initial 2 d in these experiments were within the range measured in these and other estuaries, indicating that riverine dissolved organic matter can contribute to production of estuarine bacteria. Average DON concentrations decreased by 40 to 72% within the 10 to 15 d time course of the experiments; the decreases in DON were accounted for by increases in microbial biomass plus remineralization to inorganic nitrogen. The time scale over which DON was utilized suggests that in estuaries with residence times on the order of weeks to months, such as Delaware Bay, river inputs of the biologically available portion of DON are first utilized within the estuary. In contrast, in estuaries with residences times of less than a week, such as New York Bay, a portion of the biologically available DON may be utilized first within the estuary, with the remainder exported and utilized in continental shelf waters. The large proportion of the DON that was biologically available in these experiments, coupled with the knowledge that inputs of organic nitrogen can account for 20 to 90% of the total nitrogen loading to estuaries, suggests that organic nitrogen inputs may contribute more to estuarine and shelf eutrophication than was previously suspected. These experiments demonstrate that dissolved inorganic nitrogen (DIN) inputs underestimate, and total nitrogen inputs likely overestimate, the inputs of biologically available N to estuaries. In order to develop a `biologically available nitrogen budget' for an ecosystem, DIN inputs, plus that portion of the organic N that is biologically available must be quantified.

The von Bertalanffy growth equation was fit to male and female vertebral age data. Initial growth was rapid ( approximately 200 mm TL) for both sexes from age 0-1. At age 2 growth slowed for males but continued for females. Similar to many species of sharks, females grew slower than males (K = 0.28 and K = 0.69, respectively) but attained a larger maximum size (L sub( arrow left ) = 1226 and L sub( arrow left ) = 897). Maximum age was estimated in males and females to be 8+ and 12+ years, respectively. Growth of young-of-year sharks was 21 to 30 mm TL per month determined by three different methods. A comparison of age and growth estimates from populations at more southerly latitudes suggest that clinal variation in total length may be evident among bonnethead sharks in the Gulf of Mexico with females reaching larger sizes in northern areas as compared to south Florida.

We tested the hypothesis that increased habitat heterogeneity leads to increased secondary production and diversity. Nekton densities in shallow (depths <1 m) Thalassia meadows and in mud, algae, and Halodule patches were compared 12 times over 3 yrs using a quantitative 2.6 m super(2) drop trap. Mean densities of fishes and decapods were usually significantly higher in Thalassia beds than in Halodule, algae, and mud patches. The reverse was true for species diversity and richness, which were usually significantly lower in Thalassia beds than in one or more patch types. Macrofaunal densities and species richness and diversity were usually not affected by site (two areas 15 km apart) or time (day vs. night). Six species comprised 84-99% of all organisms in each floral type. Mean densities of Lucania parva, Opsanus beta, and Thor floridanus were almost always significantly higher in Thalassia beds than in Halodule, algae or mud patches. The opposite was true for mean densities of Floridichthys carpio, which were usually significantly lower in Thalassia than elsewhere. Mean densities of Penaeus duorarum were irregularly related to plant type, and those of Gobiosoma robustum were never related to plant type. Time of collection did not affect densities of any dominant species, but mean densities of Thor and Floridichthys were significantly higher on Ninemile Bank than on Sandy Key Bank. Lower nekton standing crops and increased species richness and diversity at the local scale may lead to system-wide faunal changes. However, fisheries seem not to have been affected by seagrass mortality and associated changes in habitat heterogeneity and the forage base.

Ruffieux et al. [1995] (henceforth RPFW95) described the temporal evolution of the meteorological parameters and discussed their significance. Since publication of the paper, two errors have been found in the processing of the long-wave radiation data from the pyrgeometers. One was a processing error; the other was a theoretical error in the standard processing techniques used. These errors, especially the latter, have a quantitative effect on the data and some effect on data interpretation. The purpose of this brief report is to describe the consequences of these errors on the LEADEX data and their interpretation, and to provide corrected figures for the parameters most affected. Because of the discovery of these two errors in the calculations of long-wave radiative fluxes from the Eppley radiometers, a recalculation of the ice peak and surface energy budgets during the Arctic Leads Experiment (LEADEX) was necessary. The error principally contributing to the observed differences was in the relationships that have been used for obtaining long-wave radiative fluxes from Eppley radiometers for the past 20 years. This paper focuses on the impacts on the LEADEX data. The main impacts of the corrections of these errors are decreases in the amplitudes of the diurnal variations of the long-wave fluxes and the skin temperature; an increase in the estimate of the sensible heat transfer coefficient (C sub(H)) and the removal of its apparent diurnal cycle; and an interpretation of a more stable near-surface background atmosphere during the deployment to Lead 4. Average 10-m neutral values of the drag coefficient (C sub(D)) and C sub(H) are now found to be 1.46 x 10 super(-3) and 1.40 x 10 super(-3), respectively. JF - Journal of Geophysical Research. C.

The fish were sampled from recreational headboats operating in the Gulf of Mexico from Naples, Florida, to Port Aransas, Texas, from 1988 to 1993, and therefore, best represent age and growth of the species as harvested by this fishery. Most (53%) of the fish were landed in Texas, but others came from northwest Florida and Alabama (46%) and Louisiana (1%). The oldest fish was estimated to be age 15 and measured 1512 mm total length (1355 mm fork length). Rings formed on most otoliths between March and May, and are thus considered to be true annual marks. Back-calculated mean total lengths for 225 fish were 415, 614, 742, 839, 915, 976, 1044, 1100, 1156, 1209, 1256, 1283, 1299, 1332, and 1365 mm for ages 1 through 15, respectively. Equations were derived to convert lengths: FL = -17.7319 + 0.8847(TL), and TL = 24.2327 + 1.1247(FL). Back-calculated lengths at age were used to derive the following von Bertalanffy growth equations: TL sub(t) = 1272(1-e super(-0.2272(t+0.7931))), and FL sub(t) = 1109 (1-e super(-0.2270(t+0.7198))). Greater amberjack are fully recruited to the headboat fishery in the Gulf of Mexico at age 4. Total instantaneous mortality estimates (Z) generated from catch curves of the Gulf of Mexico headboat fishery were 0.68 for 1988 and 0.70 for 1993.

These estimates of growth were then compared to those previously estimated from various hard-part and back-calculation analyses. The three fish examined in this study, gag (Mycteroperca microlepis), greater amberjack (Seriola dumerili), and red grouper (Epinephelus morio), are all important species to both the recreational and commercial fisheries of Florida's west coast. We compared estimates of growth between the two methods by calculating the proportional error in size-at-age predicted by the two growth curves. The ages of gag observed in the fishery range from approximately age 3 to 9; within this range the maximum error occurred at age 9 and was 26 mm (2.68%). The ages of greater amberjack observed in the fishery range from approximately 1 to 5; within this range the greatest error occurred at age 1 using the otolith growth curve (156 mm, 38.61%). The majority of red grouper observed in the fishery range from approximately age 5 to 8; within this range the maximum error occurred at age 8 (-31 mm, -4.45%).

The volume of shell middens was directly correlated (r = 0.944) with the abundance of juvenile conch in the shallow surrounding waters (log-log relationship). Radiocarbon dates for shells collected from the bottoms of large middens indicated that these shell accumulations reflect a history of fishing in the region dating back more than 400 yrs. The middens probably originated with the indigenous Lucayan population, then continued to accumulate through the European invasion of the Bahamas, the British Loyalist period, and up to the present date. The distribution of shell middens indicates that the eastern Sound never had an important conch fishery, corroborating the present day low abundance of conch in the area, and advection of queen conch larvae from east to west. High shell volumes in the northern Sound reflect large conch populations and larval retention in that region. Shell middens can yield important insights into human history, and useful information on the biogeography, ecology, and long-term fisheries of heavily exploited molluscan species such as S. gigas.

The daily lifeguarding of the 17 Oahu beaches provided a documentation of effort not available from fishery data. Identified seasonal and spatial trends in shark sightings were found to persist through successive years of surveillance and were roughly consistent with distributions of fishery bycatch. However, it was possible to attribute shark bycatch to changes in accessibility of fishing grounds and size of the fishing fleet. An evaluation of the potential biases in lifeguard data indicated that variables such as wind/surf conditions and beach attendance did not govern the frequency with which sharks were reported. Summer increases in sightings coincided with shark pupping activities, and winter pulses were roughly associated with periods of increased rainfall. Relationships with coast and season were evident, with significantly more sightings on the island's leeward coast. A survey of shark-related news stories compared with reports of shark sightings suggested that shark sightings increased on a limited scale with high media exposure. No consistent trend in abundance of sharks was detected over the full 10-yr period. The interannual pattern of shark sightings (scaled for effort) remains unexplained, despite comparison with fishery data, island runoff, sea-surface temperature, and known El Nino events.

ER - TY - JOUR T1 - Comparative bioaccumulation of chlorinated hydrocarbons from sediment by two infaunal invertebrates AN - 16416520; 4311426 AB - Bioaccumulation of chlorinated hydrocarbons (CHs) from field-contaminated sediments by two infaunal invertebrates, Rhepoxynius abronius (a non-deposit feeding amphipod) and Armandia brevis (a nonselective, deposit-feeding polychaete), was examined and species responses were compared. Sediments were selected over a large geographical area of the Hudson-Raritan estuary to assess the potential for bioaccumulation from a typical urban estuary. Unlike polycyclic aromatic hydrocarbons (PAHs) from these sediments, concentrations of CHs in interstitial water (IW) indicated that partition coefficients (K sub(oc)) were generally as expected, especially when based on predicted, nonsorbed, interstitial water CH concentrations (IW sub(free)). Correlations between amphipod and polychaete tissue residues revealed that these species were responding similarly to a gradient of CH concentrations in sediment. While tissue residues and BAF sub(loc) (lipid/organic carbon normalized bioaccumulation factor) values for the trichlorobiphenyls were similar for both species, accumulation in the polychaete was three to 10 times higher for the more hydrophobic PCBs, which was attributed to differences in the route of exposure. A negative correlation between the bioaccumulation factor (BAF) and total organic carbon (TOC) was found for both species, which was expected according to equilibrium partitioning theory. Because it was assumed that the amphipod was not feeding in these tests and the polychaete was ingesting sediment, comparison of their tissue residues and bioaccumulation factors was useful for highlighting the importance of sediment ingestion, especially for short-term, nonequilibrium exposures. These results may also help elucidate the limitations associated with assessing bioaccumulation and the resultant toxic response in standard 10-day toxicity tests with similar invertebrates.

The degree of population structure ranges widely among flatfishes. Although we know that large populations tend to be subdivided into local populations, based on morphological, meristic and reproductive characteristics, these data often conflict with evidence on genetic stock structure, due to the scale and organization of movement within the metapopulation. Movement of individuals between local subpopulations and colonization events on a macroecological scale are probably important to some flatfish populations. Dispersal of larvae is known to be a major factor affecting population mixing. Some flatfishes have planktonic stages of long duration and for these species there is often, but not always, little population structure; gene flow sometimes may be limited by oceanographic features, such as eddies and fronts. At the juvenile stage dispersal can result in colonization of under-utilized habitats; however, for flatfishes with strong habitat requirements, this type of event may be less likely when suitable habitats are fragmented. Complex population structure has major implications for management, e.g. lumping harvested populations with little gene flow can have detrimental local effects. Moreover, the issue of population structure and movement influences the interpretation of research data, where populations are generally treated as closed systems. There is currently a strong need for a multidisciplinary approach to study fish population dynamics and the structure of their populations. This research should involve molecular geneticists, population geneticists, animal behaviourists and ecologists. Migration mechanisms, colonization and extinction events, gene flow and density-dependent movements are subject areas of great importance to managing large harvested populations, but our understanding of them at ecological scales, at least for marine fishes, is at a rudimentary level.

Several periods of depleted ozone were observed, representing the lowest latitude measurements of springtime surface polar ozone depletion in the northern hemisphere to date. The most severe ozone depletion occurred during 14-17 March, when surface ozone levels abruptly fell to below 10 ppbv from typical values of about 40 ppbv. Simultaneous near-ultraviolet and visible total column spectroscopic measurements were made with ground-based instruments, yielding total column values for BrO and OClO. Elevated levels of BrO were observed at the onset of ozone depletion episodes and the behavior of BrO slant column values through the morning twilight of 15 March indicated that the BrO column must reside in the boundary layer. The boundary layer BrO mixing ratio was estimated at greater than 13 pptv during this episode. OClO levels showed no correlation with surface ozone depletion nor clear evidence of a large tropospheric burden. JF - Tellus.

This work examines whether repeated exposure to subsymptomatic or symptomatic nonlethal doses of domoic acid leads to enhanced symptomatic toxicity in ICR outbred and DBA inbred strains of laboratory mice. A multiple independent exposure paradigm was designed in which doses were administered intraperitoneally every other day for 7 days to achieve four separate exposures to domoic acid. We first examined the effect of repeated exposure on serum clearance of domoic acid. Serum domoic acid levels did not differ following a single or repeated exposure. We next examined the effect of repeated exposure on symptomatic toxicity. The mean toxicity scores did not show a significant difference between single and repeated exposures of either subsymptomatic (0.5 mg/kg) or symptomatic sublethal (2.0 mg/kg) doses of domoic acid. We then examined the effects of repeated domoic acid exposure on a second strain of mouse. DBA mice were chosen based upon their sensitivity to kainic acid-induced seizures; however, the ICR mice were more sensitive to low-dose domoic acid toxicity, particularly in terms of onset and duration of stereotypic scratching behavior. Our results indicate that both strains of mice have comparable concentration-dependent toxic responses to domoic acid; however, differences exist in the magnitude of the response and in specific symptoms. The mean toxicity scores did not show a significant difference when a single exposure (1.0 and 2.0 mg/kg domoic acid) and repeated exposure of the same dose were compared in the DBA mice. This study provides no evidence that short-term repeated exposure to domoic acid in laboratory mice alters domoic acid clearance from the serum, or leads to a more sensitive or a greater neurotoxic response.

The Regional Atmospheric Modeling System (RAMS) was evaluated against buoy data over the Chesapeake Bay. Turbulence and surface layer variables (e.g., surface fluxes, friction velocity) and ultimately deposition velocities were primarily examined against the buoy data for 23 cases in 1994. Sensible heat fluxes and temperatures compared well with observations when the model horizontal resolution was reduced to 5 km or less and the first model level were 12 m. Other turbulent variables compared poorly especially under stable stratifications. Overall, latent heat fluxes and deposition velocities were significantly under predicted even with these finer resolutions. Results degraded when the effects of clouds on short- and long-wave radiation were incorporated. Results were also insensitive to increase in the initial sea surface temperature (SST) over the observed daytime range (1 degree C), and to the use of an improved roughness length parameterization over water. Errors were much larger during stably stratified conditions, therefore, substantial under prediction of pollutants to the bay would be expected by RAMS during stable periods. However, RAMS would be a reliable predictor of fluxes and deposition velocity during unstable conditions. Further experiments were done to help explain the poor predictions during the daytime for stable conditions. Fluxes over water were strongly sensitive to the soil moisture content of the surrounding land masses for stable atmospheric conditions and improved when geostrophic forcing terms were added to the momentum equations. However, the improved results given with geostrophic forcing were either representative of synoptic forcing or a decoupled layer from the surface that could not be resolved.

From 1840 to the mid-20th century, the Arctic warmed to the highest temperatures in four centuries. This warming ended the Little Ice Age in the Arctic and has caused retreats of glaciers, melting of permafrost and sea ice, and alteration of terrestrial and lake ecosystems. Although warming, particularly after 1920, was likely caused by increases in atmospheric trace gases, the initiation of the warming in the mid-19th century suggests that increased solar irradiance, decreased volcanic activity, and feedbacks internal to the climate system played roles.

Currently, the network operates as a component of the Clean Air Status and Trends Network (CASTNet). Dry deposition is not measured directly in CASTNet, but is determined by an inferential approach (i.e. fluxes are calculated as the product of measured ambient concentration and a modeled deposition velocity). Chemical species include ozone, sulfate, nitrate, ammonium, sulfur dioxide, and nitric acid. The temporal resolution for the ambient concentration measurements and dry deposition flux calculations is hourly for ozone and weekly for the other species. This paper describes the 50-station CASTNet dry deposition network, discusses dry deposition calculation procedures and presents dry deposition data for sulfur dioxide and nitric acid for 1991. Sources of uncertainty in dry deposition estimates are also discussed. JF - Atmospheric Environment AU - Clarke, J F AU - Edgerton, E S AU - Martin, B E AD - Atmos. Sci. Modeling Div., Air Resour.

AN - 16354168; 6611 AB - PURPOSE: The consolidation of National Marine Fisheries Service (NMFS) research and administrative facilities located in Juneau, Alaska, is proposed. The NMFS operates numerous programs and facilities in various locations throughout Alaska. The two largest NMFS programs in the Juneau area are the NMFS Alaska Regional Office (ARO) and the Auke Bay Laboratory (ABL), which is associated with the Alaska Fisheries Science Center in Seattle, Washington. The two facilities, which are located in different parts of Juneau, collaborate in the development of fishery management policies and regulations for the fisheries off the Alaska coast. The ARO is located in rented General Services Administration office space in the federal building in downtown Juneau. The ABL, which provides the scientific research needed to support fishery management decisions, is located on a 3.5-acre site located 12 miles northwest of Juneau. Four alternatives, including a No Action Alternative, were considered in the draft EIS of September 1996. This draft supplement considers one additional alternative, which would involve locating the consolidated facility on the 22-acre Lena Point site, which is now operated as a rock quarry. The draft EIS had identified the 28-acre undeveloped site at Auke Cape as the preferred alternative; the site has been transferred from the U.S. Coast Guard to the NMFS. Access to the site would be provided by developing the existing National Park Service (NPS) road and Otter Way through the Indian Cove community. The facility would include approximately 88,000 gross square feet (gsf) of administrative office space and common areas, 58,000 gsf of laboratory space, and 3,800 gsf of warehouse space. The site would be built to accommodate 273 employees and visitors. The estimated project development costs are $65.0 million to $70.0 million. POSITIVE IMPACTS: The consolidation of the two facilities would improve the overall efficiency of program operations and reduce administrative costs. NEGATIVE IMPACTS: The construction of the project would adversely affect homes located along the NPS road. The increased traffic along the road would increase noise levels and adversely affect the community character.

AN - 79445408; 9391987 AB - A stingray spine was found lodged in the scapula of a deceased 272 cm, male bottlenose dolphin (Tursiops truncatus) from South Carolina (USA) following skeletal preparation, nearly 6 mo after necropsy. No external puncture wound, internal bruising, or laceration of muscle tissue surrounding the scapula was evident during necropsy of the animal. Implantation of the spine did not appear to be related to the death of the dolphin, but probably occurred at an early age. Abnormal development of bone surrounding the spine resulted in the formation of a cavity at the wound site. Two mechanisms were considered as contributors for the cavity formation. These were the mechanical action of the spine stimulating the body's defense system for managing foreign objects, and the release of potent toxins from the spine sheath.

AN - 79309015; 9326903 AB - In clinical tooth preparation with diamond burs, sharp diamond particles indent and scratch the enamel, causing material removal. Such operations may produce subsurface damage in enamel. However, little information is available on the mechanisms and the extent of subsurface damage in enamel produced during clinical tooth preparation. The aim of this study, therefore, was to investigate the mechanisms of subsurface damage produced in enamel during tooth preparation by means of diamond burs, and to examine the dependence of such damage on enamel rod orientation, diamond particle size, and removal rate. Subsurface damage was evaluated by a bonded-interface technique. Tooth preparation was carried out on two enamel rod orientations, with four clinical diamond burs (coarse, medium, fine, and superfine) used in a dental handpiece. The results of this study showed that subsurface damage in enamel took the form of median-type cracks and distributed microcracks, extending preferentially along the boundaries between the enamel rods. Microcracks within individual enamel rods were also observed. The median-type cracks were significantly longer in the direction parallel to the enamel rods than perpendicular to the rods. Preparation with the coarse diamond bur produced cracks as deep as 84 +/- 30 microns in enamel. Finishing with fine diamond burs was effective in crack removal. The crack lengths in enamel were not significantly different when the removal rate was varied. Based on these results, it is concluded that subsurface damage in enamel induced by tooth preparation takes the form of median-type cracks as well as inter- and intra-rod microcracks, and that the lengths of these cracks are sensitive to diamond particle size and enamel rod orientation, but insensitive to removal rate.

AN - 62543531; ED418708 AB - The Department of Commerce's Telecommunications and Information Infrastructure Assistance Program (TIIAP) is designed to address technology needs in the public and nonprofit sectors of the United States. This report is one of many ways that TIIAP is sharing the stories and the lessons that are being learned by recipients of TIIAP awards. The case studies in this report describe early experiments in building and using the information infrastructure; profiles are offered of how medical centers, schools and universities, police departments, social service organizations, state and local governments, Native American tribes, and others are using technology to reach the people in their communities. It shows how the elderly can receive better health care in their homes, how police officers can more easily locate suspects or track down stolen vehicles, and how residents of inner city public housing projects can participate more directly in their children's education. These projects show that the information revolution is not so much a process by which technology is changing society as one in which people are using technology to pursue their own goals for economic growth, educational opportunity, public safety, improved health, responsive government, and strong communities.

The sediment consists mainly of biogenic CaCO (sub 3) ; the analytical results for Fe, Al, Mn, Cu, Zn, V, Pb, REE, and isotope distributions of Be, Pb and U series radionuclides are tabulated, the metal and REE concentrations being on a carbonate-free basis. The geochemical signatures indicate inputs of biogenic, lithogenic and hydrothermal origin, the latter by increased concentrations of Fe, Cu, Zn and Pb and shfits in Pb isotopic compositions toward non-radiogenic (MORB/hydrothermal) values. REE concentrations vary with hydrothermal Fe down-core. Shale-normalized REE patterns are consistent with a plume-particle fallout origin. Sediment accumulation rates of 0.54 cm/1000 yr over the past approximately 200 000 yr are indicated by variations in down-core (super 230) Th (sub xs) activity. (super 10) Be (sub (0)) / (super 230) Th (sub xs(0)) ratios indicate that hydrothermal scavenging by plume-particle Fe oxyhydroxides may focus dissolved oceanic (super 10) Be into ridge-flank sediments.

In 1935, the area was designated Fort Jefferson National Monument, the World's first underwater National Park unit. Central to the area is Fort Jefferson, America's largest coastal nineteenth century masonry fort. In 1992 it was re-designated Dry Tortugas National Park. Because of the islands' unique location, the first tropical marine biological laboratory in the Western Hemisphere was established on Loggerhead Key by the Carnegie Institution of Washington, Washington, D. C. Following the closure of the Tortugas Laboratory in 1939, aperiodic marine biological assessments have been conducted in response to manmade and natural environmental perturbations. This annotated bibliography is an attempt to provide researchers and resource managers with access to the rapidly accumulating body of information on the park's natural resources. A total of 424 references (published and unpublished) on scientific studies in, (and what later became) Dry Tortugas National Park were annotated and indexed according to major scientific topics. Studies from a wider area were included if they also sampled in Dry Tortugas National Park.

Images were acquired during eclipses (Io in Jupiter's shadow) via the SSI clear filter ( approximately 0.4-1.0 mu m), detecting emissions from both small intense hot spots and diffuse extended glows associated with Io's atmosphere and plumes. A total of 13 hot spots have been detected over approximately 70% of Io's surface. Each hot spot falls precisely on a low-albedo feature corresponding to a caldera floor and/or lava flow. The hot-spot temperatures must exceed approximately 700 K for detection by SSI. Observations at wavelengths longer than those available to SSI require that most of these hot spots actually have significantly higher temperatures ( approximately 1000 K or higher) and cover small areas. The high-temperature hot spots probably mark the locations of active silicate volcanism, supporting suggestions that the eruption and near-surface movement of silicate magma drives the heat flow and volcanic activity of Io.

The deep flow in the region, associated with the deep western boundary current, forms a pattern of strong, narrow currents and cyclonic gyres close to the continental slope with broad, slower southward flow offshore. The CFCs reveal that the most recently 'ventilated' water (i.e., having the highest CFC concentrations due to more recent contact with the atmosphere in the northern North Atlantic) is found along the western boundary in two distinct cores between potential temperatures 4 degree -6 degree C and 1.9 degree -2.4 degree C. Geostrophic transport streamlines were constructed for the deep flow, referenced using direct velocity observations at 26.5 degree N and assuming mass conservation between closed areas bounded by the hydrographic sections. The tracers and transports are used together to describe the deep circulation in the region, to determine the origins and pathways of the various flow components, to define the spatial scales and strengths of the deep currents and recirculation gyres, and to examine their relationship to bottom topography and their possible role in ventilating the interior. The close correspondence of the tracer distributions with the regional bottom topography implies that the major topographic features in this region strongly influence the deep circulation. The geostrophic transport for the narrow branch of current having the highest CFC concentration, which transits the region and continues equatorward adjacent to the western boundary, is 31 Sv (Sv [imgchar=http://ams.allenpress.com/charent/iso_characters_mixed/lo w ercase/equiv.gif] 10 super(6[/supscript] m) super(3)[/supscript] s super(-1[/supscript]) below 6 degree C. A cyclonic gyre with one or more embedded gyres extends offshore of the narrow boundary current out to about 74 degree W, transporting 12 Sv of water with intermediate CFC concentrations. Farther offshore, a broad band of southward flow contributes an additional 16 Sv of water with considerably lower CFC concentrations. Thus there is a total deep (<6 degree C) equatorward transport through the study area along the western boundary of 47 Sv at 24 degree N. The layer containing the shallower CFC core (4 degree -6 degree C) appears to be less constrained by the bottom topography. Within this temperature layer, one current branch with high CFC and low salinity flows southward along the Blake Escarpment. However, there is another branch of flow within this layer that forms an extended zonal high CFC and high salinity distribution from the eastern to the western bounds of the study region. This second branch apparently originates in the Gulf Stream recirculation and carries the higher salinity influence of the Mediterranean Water.)

National Status and Trends Program for Marine Environmental Quality AN - 18566899; 4466663 AB - The toxicity of sediments in Pensacola, Choctawhatcheee, St. Andrew and Apalachicola Bays was determined as part of bioeffects assessments performed by NOAA's National Status and Trends Program. The objectives of the survey were to determine: (1) the spatial patterns in toxicity throughout each bay, (2) the spatial extent of toxicity throughout and among the bays, (3) the severity of degree of toxicity, and (4) the relationships between chemical contamination and toxicity. The survey was conducted over two years: Pensacola Bay and St. Andrew Bay were sampled in 1993; and Choctawhatchee Bay, Apalachicola Bay and Bayou Chico (a sub-basin of Pensacola Bay) were sampled during 1994. Surficial sediment samples were collected from 123 randomly-chosen locations throughout the five areas. Multiple toxicity tests were conducted on all samples, and chemical analyses were performed on 102 of the 123 samples. Toxicological tests were conducted to determine survival, reproductive success, morphological development, metabolic activity, and genotoxicity; all bays showed toxicity in at least some of the samples.

N1 - Last updated - 2014-05-07 ER - TY - BOOK T1 - Sustainable Development: The Integration of Economic Growth, Environmental Protection, and Social Equity AN - 17694701; 4781548 AB - Environmental problems, such as ocean and air pollution and resource degradation, affect every nation's economic prosperity, political stability, social fabric, and health of available natural resources. Environmental degradation is compounded by an expanding world population, especially in coastal areas with 60 percent of the global population living within 100km of the coast. Sustainable development is a new decisionmaking process which ensures that economic growth is linked to environmental stewardship within a framework of social equity. Sustainable development involves building consensus among stakeholders, forming partnerships, and integrating participatory bottomup management. Sustainable development is the essence of activities such as the redevelopment of brownfields, the creation of ecoindustrial parks, and the formation of natural disasterresistant communities. A growing economy and healthy environment are essential to achieving sustainability and global security. The Office of Sustainable Development and Intergovernmental Affairs (SDIA) at the National Oceanic and Atmospheric Administration (NOAA) is one of several similar offices in the federal government. SDIA responds to marine fisheries crises and focuses on community initiatives to promote sustainable development. SDIA also provides a focus for sustainable development initiatives within the U.S. Department of Commerce. In 1993, the President's Council on Sustainable Development (PCSD) was created to provide guidance on how to achieve sustainability. PCSD Members have found that forging strong partnerships, creating goals, and broadbased input at the community level are important in leading the nation toward sustainability. In 1996, the Joint Center for Sustainable Communities, a project of the National Association of Counties and the U.S. Conference of Mayors was created with initial funding from SDIA and other Federal agencies to help local officials incorporate principles of sustainable development into management of their communities. Sustainable development must be a global concept implemented at the local level for the benefit of future generations.

The temporal and spatial patterns of catch-per-unit-of-effort (CPUE) and gut-fullness values were used to infer bluefish movement and feeding periods, respectively. Estimates of daily ration were made from gut-fullness values and previously published estimates of gastric evacuation rate. Nearshore beach-seine CPUE was highest during day collections and lowest at night. Offshore gill-net CPUE was highest during crepuscular or night periods and lowest during day sets. Hence, YOY bluefish appear to occupy nearshore environments during the day and move away from shore at night. Gut-fullness values for bluefish captured with beach seines were highest at diurnal and crepuscular periods and declined at night; however, there were indications of night feeding on some dates. The magnitude and pattern of daily ration estimates of YOY bluefish in the Hudson River estuary were similar to values measured in previous studies with other methods. Interannual differences in the magnitude of daily ration were observed and may be a result of day-to-day variation in feeding or differences in available prey type and size. Clupeids, striped bass, and bay anchovy were important prey in 1992, whereas striped bass, bay anchovy, and Atlantic silversides were the dominant prey of YOY bluefish in 1993. Improved understanding of the spatial and temporal patterns of bluefish feeding, as well as fine-scale temporal resolution of estimates of bluefish consumption rates, will aid in assessing the impact of YOY bluefish predation on fish populations within the Hudson River estuary.

The focus is on the antecedent and subsequent atmospheric conditions over the conterminous United States relative to the onset of monsoon precipitation over the southwestern United States, which typically begins in early July. The onset of the monsoon in this region is determined using a precipitation index, based on daily observed precipitation for a 31-yr (1963-94) period. Lagged composites of the observed precipitation and various fields from the NCEP-NCAR reanalysis for the period 1979-94 provide a comprehensive picture of atmospheric conditions during the evolution of the U.S. warm season precipitation regime. The summer precipitation regime is characterized by an out-of-phase relationship between precipitation over the Southwest and the Great Plains-northern tier and an in-phase relationship between precipitation over the Southwest and the East Coast. Changes in the upper-tropospheric wind and divergence fields (mean vertical motion) are broadly consistent with the evolution of this precipitation pattern. Enhanced upper-tropospheric divergence in the vicinity and south of the upper-tropospheric monsoon high coincides with enhanced uppertropospheric easterlies and Mexican monsoon rainfall after onset.

The size range of individuals at this site was 1.5-5 cm total length. Additional observations at other sites showed that 0-year silver hake only occurred on silt-sand bottom with amphipod tubes at bottom water temperatures of 8.7-11.4 degree C. This distribution pattern could be the result of either selective settlement into appropriate habitats or differential predation with higher survivorship in more complex habitats. We posit that 0-year silver hake occur in patches of dense amphipod tube cover to avoid visual predators and co-occur with preferred prey (i.e., amphipods and shrimps).

Spatial monitoring of seagrass meadows can improve coastal management and research with baseline inventories of change in location and areal extent through time. Vertical aerial photography is an effective but expensive approach for monitoring seagrass meadows. Remote sensing with Landsat TM is less expensive but image selection is critical because environmental factors affect detection of seagrass meadows. Interpretation of photographs (March 1985 and April 1988) provides reference data for evaluation of results with three Landsat TM images of coastal North Carolina. Agreement of the Landsat classification with reference data was as high as 72.6% for a June 1992 image. Despite limited development of coastal North Carolina, seagrasses closely associated with the mainland are relatively low in abundance and are restricted to shallower water than seagrasses nearer the uninhabited barrier islands.

This variable, an alternative to the measure of total precipitation, has not previously been used in dendroclimatic reconstructions. However, it may be a more meaningful measure of seasonal rainfall and indicator of anomalies in atmospheric circulation features than total precipitation in areas such as the arid Southwest, where the distribution of rainfall is spatially variable. The number of precipitation days in the region encompassing southwestern New Mexico and southeastern Arizona was reconstructed for the time period 1702-1983 from a collection of tree-ring chronologies in this area. Results from this study show that tree-ring chronologies explain 71% of the variance in the regional record of the number of precipitation days. The reconstruction is statistically verified and validated with independent data. Tree-ring chronologies in this region are better able to explain variations in precipitation-day numbers than total precipitation, suggesting that other dendroclimatic studies may benefit from the use of this variable as well.

The GPI, based on the results of studies relating fractional coverage of cold cloud to convective rainfall, uses IR observations gathered by geostationary and polar-orbiting satellites. Longitudinal discontinuities in mean GPI coincident with the boundaries of satellite coverage led to a comparison of GPI derived from each geostationary satellite in overlap regions. This study revealed both intersatellite calibration differences and satellite zenith angle dependence. Its goals are to remove these sources of systematic error within the GPI, investigate the climatology of the corrected GPI, and compare against other estimated rainfall datasets. To correct calibration differences, Global Precipitation Climatology Project geostationary satellite IR data are standardized to one satellite by temperature adjustments deduced by the International Satellite Cloud Climatology Project. The resulting GPI values are corrected for zenith angle dependence based on a comparison between GOES-7 and Meteosat-3 that found a systematic increase in GPI of 9% for every 10 degree of zenith angle beyond 25 degree . The corrections remove noticeable discontinuities in time-averaged GPI and are largest (>2 mm day super(-1)) over the eastern Indian Ocean, the equatorial Pacific near the date line, and South America. The spatial correlation between corrected GPI and rainfall derived from rain gauges is greater than 0.8 in tropical regions with adequate gauge density. Empirical orthogonal functions of monthly anomalies of corrected GPI show the expected El Nino-Southern Oscillation spatial pattern.

The relation between the intrinsic rate of natural increase and population variability was determined. The intrinsic rate of increase is related positively to temperature. For the parameter regime considered, the intrinsic rate of increase depends on age-at-maturity and the number of replacements each spawner can produce at low population densities. The covariation of temperature and the intrinsic rate of increase results from the influence of temperature on age-at-maturity.

The recent low landings may be due to large numbers of young fish killed as bycatch in the southern shrimp fishery and as scrap catch in other fisheries. Yield-per-recruit models are needed to develop appropriate fisheries management measures. Stock assessment data from Chesapeake Bay in 1988-91 were used to evaluate the effects of fishery-induced vs. natural mortality and age-at-first-capture schedules on Atlantic croaker yield-per-recruit. Model results suggest that yield-per-recruit could be maximized by reducing the current level of age at first capture, but gains are small and may not be justifiable. Other regulatory measures should be used to maintain the current level of age-at-first-capture in the lower Chesapeake Bay. In North Carolina, the opposite pattern exists, probably because of growth-overfishing. Differences between Chesapeake Bay and North Carolina croaker may reflect temporal, rather than spatial, differences in population dynamics.

To test whether the unprecedented herring population crash of 1993 was a delayed response to the oil spill, mature herring were collected from four sites in the sound and three uncontaminated sites in spring 1995. These herring were spawned artificially and the eggs were reared in a laboratory until hatching. Fertilization success, hatching times, hatching success, larval viability, swimming ability, and spinal abnormalities were determined. No significant differences were observed in any of these parameters between sites for any year classes of herring. Examination of a subset of samples for yolk and pericardial abnormalities also showed no significant differences. No reproductive impairment of Pacific herring in Prince William Sound was observed in 1995.

Long-term life history data and increased fishing pressure data were used to test the impact of sustained exploitation on red porgy populations. Temporal changes in age, growth, and reproduction of red porgy for four time periods during 1972-94 were analyzed, with emphasis on annual changes in age and growth from 1988-94. Size-at-age, size-at-maturity, and size-at-sexual-transition calculations for the four time periods show decreasing trends that may be a response to sustained 20-year overexploitation that has selectively removed individuals that are predisposed to rapid growth and larger size.

Fathers as Care Providers. Current Population Reports. Household Economic Studies. AN - 62455834; ED424916 AB - This report examines statistical data on fathers caring for their children during mothers' working hours and which types of fathers are the most likely to take care of their children. Data are taken from the Survey of Income and Program Participation, a longitudinal survey conducted at four-month intervals by the Census Bureau. Care by fathers is considered to encompass, to some extent, all three of the components of fathers' involvement: interaction, availability, and responsibility. Fathers are more likely to care for their preschool-age children than for their grade school-age children. The article discusses changes in proportions of married fathers who care for their preschoolers while the mothers are at work. The likelihood of fathers being caregivers is related to employment status and occupation, the effect of the economy, family's financial status, veteran status, geographic location, residence in city or suburb, and number of children. Charts and graphs of the data are presented. (JPB) AU - Casper, Lynne M.

However, high-range perigean spring tides occurred only a week later, illustrating how accurately occurrence times must be known to constrain the region's background water levels during such events. The ranges of background water levels increase northward from 3 m at Monterey to 8.5 m at Queen Charlotte, as estimated from the amplitudes of perigean spring tides and subtidal winter fluctuations.

National Status and Trends Program for Marine Environmental Quality AN - 17577688; 4467135 AB - Dated cores collected from different sites in the Savannah Estuary were analyzed for 16 metals, 22 polycyclic aromatic hydrocarbons (PAH), 20 polychlorinated biphenyls (PCB) congeners, 16 pesticides and 3 butylins. Time stratigraphy of the cores were determined by measurements of Pb- 210 and Cs-137 activities down the cores. Those chemicals which showed significant temporal changes down dated cores in the Savannah Estuary included mercury, lead, chromium, PAHs, DDT isomers and metabolites, PCBs and dieldrin. The present study used cores from the Savannah Estuary, where the population is relatively low (approximately 150,000) and industrial growth has occurred over the past 30 years. Thus, the concentrations of most anthropogenic chemical found in the cores of the Savannah Estuary were comparatively low. An interesting aspect of the study, which has been noted by many pollution history studies, was the decrease in the concentration of anthropogenic chemicals during the past two decades suggesting that many pollution control laws have been effective, even while industrial and population growth continues in an area. In summation, the authors' studies present evidence of relatively large inputs of anthropogenic chemicals, including mercury, chromium, lead, polycycloic aromatic hydrocarbons, dieldrin, DDT isomers, and polychlorinated biphenyls, during the 1950s and 1960 into the Savannah Estuary followed by a gradual decrease of these chemicals during the past 20 to 30 years.

Because of on going interest in the impacts of human-made sound on MBNMS resources, the SAC requested that the NBNMS Research Activities Panel (RAP) provide an overview of the topic. The RAP felt a comprehensive overview would be an extensive project, and hat the MBNMS should direct more funds to fill gaps in knowledge for these types of resource management questions. However, they agreed to work with MBNMS staff to develop an annotated bibliography on the sound topic. References were compiled using Aquatic Sciences and Fisheries Abstracts, Melvyl (Univ. of California's literature search system), RAP member references collections, the bibloiography of the MBNMS Site Characterization, and the Acoustic Thermometry of Ocean Impact (ATOC) Environmental Impact Statement. When available, an abstract of the publication was included.

N1 - Last updated - 2015-03-24 ER - TY - JOUR T1 - Oceanic rainfall detection and classification in tropical and subtropical mesoscale convective systems using underwater acoustic methods AN - 16447207; 4345071 AB - Measurements of the underwater sound produced by rain were made at three U.S. coastal sites in a study to determine the feasibility and limitations of the acoustic detection and classification of rainfall over water. In the analysis of the rain sound spectra, concurrent radar reflectivity observations were used to identify convective and stratiform regions of the precipitating clouds overhead. It was found that acoustic classifications of rainfall as to type, based on information in the 4-30-kHz frequency band, were in general agreement with radar-derived classifications. The classification technique is based on use of an acoustic discriminant, D sub(R), defined as the difference in average spectral levels between the 10-30- and 4-10-kHz bands. A high correlation was found between sound spectrum levels (in decibels) in the 4-10-kHz frequency band and radar reflectivity, dBZ, suggesting the possible use of the 4-10-kHz band sound spectral level as a classification tool using spatially distributed hydrophones in the same way that radar reflectivity is used in classifying precipitation. The results demonstrate the feasibility of the acoustic method for detecting and classifying rainfall at sea.

To characterize various patterns of variation, time series of catch, catch per unit effort, or biomass from 30 stocks were examined with a variety of statistical methods including autocorrelation analysis and Lowess smoothing. A hierarchical cluster analysis classified the stocks into six identifiable groups: steady-state; low-variation, low-frequency; cyclic; irregular; high-variation, high-frequency; and spasmodic. The observed patterns are consistent with life history traits; for example, stocks with high variability are generally small, pelagic species whereas low-variability stocks are generally slow-growing, demersal fish. Each of the six general patterns of variability can be produced from a simple multiple-equilibrium population model by varying the intrinsic rate of population growth, and the time scale and amplitude of environmental variability. Suitable management policies depend on the type of variation observed, and the vast majority of stocks examined do not correspond to the steady-state assumptions of classical fisheries models. For example, management of spasmodic stocks may alternate between periods of active exploitation and periods of rebuilding, a process enhanced by the existence of alternative fisheries.

Debris on beaches and in water has been attributed to beach goers, recreational and commercial boaters, oil platforms, and debris from our streets washing down storm drains (Pruter, 1987). The general public has been made aware of the marine debris problem through local and international beach and waterway clean-up campaigns. However, people are generally not aware of the magnitude of the debris problem in offshore waters. Lecke-Mitchell and Mullin (1992) reported floating debris to be both abundant and widely distributed in the north-central Gulf of Mexico. Now, based on compilation of results from aerial surveys conducted over larger areas of the US Gulf of Mexico by the National Marine Fisheries Service, Southeast Fisheries Science Center, the marine debris (plastic, rope, oil slicks) problem can be characterized as Gulf-wide and just as much of a problem in offshore waters as on beaches.

During this episode, nearly continuous, eddy covariance measurements of carbon dioxide and water vapour fluxes were acquired over a temperate, hardwood forest. These data are used to examine how environmental factors and accumulating soil moisture deficits affected the diurnal pattern and magnitude of canopy-scale carbon dioxide and water vapour fluxes. The field data are also used to test an integrative leaf-to-canopy scaling model (CANOAK), which uses micrometeorological and physiological theory, to calculate mass and energy fluxes. When soil moisture was ample in the spring, peak rates of net ecosystem CO sub(2) exchange (N sub(E)) occurred around midday and exceeded 20 mu mol m super(-2) s super(-1). Rates of N sub(E) were near optimal when air temperature ranged between 22 and 25 degree C. The accumulation of soil moisture deficits and a co-occurrence of high temperatures caused peak rates of daytime carbon dioxide uptake to occur earlier in the morning. High air temperatures and soil moisture deficits were also correlated with a dramatic reduction in the magnitude of N sub(E). On average, the magnitude of N sub(E) decreased from 20 to 7 mu mol m super(-2) s super(-1) as air temperature increased from 24 to 30 degree C and the soil dried. The CANAOK model yielded accurate estimates of canopy-scale carbon dioxide and water vapour fluxes when the forest had an ample supply of soil moisture. During the drought and heat spell, a cumulative drought index was needed to adjust the proportionality constant of the stomatal conductance model to yield accurate estimates of canopy CO sub(2) exchange. The adoption of the drought index also enabled the CANOAK model to give improved estimates of evaporation until midday. On the other hand, the scheme failed to yield accurate estimates of evaporation during the afternoon. JF - Plant, Cell & Environment AU - Baldocchi, D AD - Atmos.

AN - 79234418; 9268300 AB - The role of surface amino acid residues in the interaction of putidaredoxin (Pdx) with its redox partners in the cytochrome P450cam (CYP101) system was investigated by site-directed mutagenesis. The mutated Pdx genes were expressed in Escherichia coli, and the proteins were purified and studied in vitro. Activity of the complete reconstituted P450cam system was measured, and kinetic parameters were determined. Partial assays were also conducted to determine the effect of the mutations on interactions with each redox partner. Some mutations altered interactions of Pdx with one redox partner but not the other. Other mutations affected interactions with both redox partners, suggesting some overlap in the binding sites on Pdx for putidaredoxin reductase and CYP101. Cysteine 73 of Pdx was identified as important in the interaction of Pdx with putidaredoxin reductase, whereas aspartate 38 serves a critical role in the subunit binding and electron transfer to CYP101.

AN - 36402155; 6574 AB - PURPOSE: The implementation of a coastal management program prepared by the state of Georgia is proposed. Approval would allow program administrative grants to be awarded to the state and require that federal actions be consistent with the program. Georgia's coastal area extends from three miles seaward to approximately 60 miles inland. Twice each day an eight-foot tide pushes seawater up the coastal rivers, affecting the plants, fish, and ecology of coastal rivers and wetlands. The coastal area is important economically for a number of industries, including shrimping, crabbing, recreational fishing, tourism, and manufacturing. Issues of concern include water supply limitations, the identification of historic sites, the impacts of economic activities on endangered species, beach erosion and hazard problems, water quality degradation, declining fishery populations, increased population growth, dredging and material disposal, the lack of beach access, the vulnerability of the barrier islands, and the need for energy planning. As lead agency for the program, the Department of Natural Resources is responsible for monitoring saltwater stocks, enhancing marine access, constructing inshore artificial reefs, managing resources, monitoring coastal water quality, implementing the National Shellfish Sanitation Program, reviewing and granting permits for economic developments in marshes and along the shoreline, providing technical assistance on endangered species and habitats, and reviewing compliance with federal regulations. Three alternatives are considered in this draft EIS: approval of the program, denied approval, and delayed implementation. POSITIVE IMPACTS: The implementation of the program would improve accountability, responsiveness, and coordination among numerous federal, state, and local government agencies with jurisdiction in the coastal area. In addition, the program would foster permit simplification and improved regulatory compliance. The program would enable the state to balance the conservation of coastal resources with the recognized need for rational economic growth. NEGATIVE IMPACTS: The adverse effects associated with the siting of major defense, transportation, and energy facilities would continue. LEGAL MANDATES: Coastal Zone Management Act of 1972 (43 U.S.C. 1241).

The seal hauled out during the day and dived continually when in the water at night. Dives averaged110 m deep and 6.4min long; the deepest dive was 212m and the longest 9.8min. Dives were deepest near twilight and shallowest at night; this pattern suggests that the seal's prey, presumably mid-water squid and fish, may have been making vertical migrations or changing predator-avoidance behavior in response to diel light patterns. The dives of this Ross seal were substantially deeper, on average, than those of crabeater seals (Lobodon carcinophagus), which forage in the same areas on Antarctic krill (Euphausia superba).

Two-dimensional inversions of the data indicate that the upper crustal part of the San Andreas fault does not appear here as an anomalously conductive zone. Additionally, a broad resistive zone under the Temblor Mountains (east of the fault) suggests resistive crystalline or metamorphic rocks may be present here as opposed to the more conducting Franciscan assemblage, contradicting the generally-accepted geologic model.

The Data Management Committee (DMC) of the EIIP was charged with the goal of developing the data exchange standard, and undertook the task of developing a data model on which to base the data exchange format. The purpose of developing the data model was to establish a standardized set of data relationships which reflect physical reality and ensure accurate and consistent reporting of emissions and emission related data.

The authors also demonstrated the modular functionality of the CMAQ science process codes by comparing results with different numerical algorithms for a regional scale air quality simulation. The Models-3/CMAQ system achieves multipollutant and multiscale capability by combining several distinct modeling techniques. First, the authors recast the governing atmospheric diffusion equation in a generalized coordinate system to accommodate many different meteorological coordinates and assumptions on atmosphere. Second, CMAQ uses a nesting capability to refine grid resolutions to apply to the small-scale air quality problem. Third, a Plume-in-Grid module allows the computation of subgrid scale plume-scale dispersion and reactions. Finally, the multi- pollutant capacity is provided by a generalized mechanism chemistry reader, generalized mechanism chemistry reader, generalized chemistry solvers, linked aqueous reaction processor, and aerosol modules.

N1 - Last updated - 2011-12-13 ER - TY - JOUR T1 - Bathymetric demography, enzyme activity patterns, and bioenergetics of deep-living scorpaenid fishes (genera Sebastes and Sebastolobus): Paradigms revisited AN - 16414402; 4328083 AB - Previous metabolic studies of scorpaenid fishes have measured inter- and intra-specific differences in physiological and biochemical capacities in fishes living at different depths. Small sample sizes and undocumented provenance of the samples studied have not allowed a full examination of the environmental basis for metabolic adaptation. The objective of this study was to determine the bathymetric demography of 22 scorpaenid fishes of the genera Sebastes and Sebastolobus, and to examine inter- and intra-specific changes in metabolic capacity in 4 of them (Sebastes goodei, Sebastes diploproa, Sebastolobus alascanus and Sebastolobus altivelis) representative of different environmental conditions. We attempted to collect samples that spanned the full depth and size ranges of each species. We examined changes in metabolic capacity as it was affected by size, depth of occurrence, and the existence of an oxygen minimum zone (OMZ) centered at 800 m. Lactate dehydrogenase (LDH) was measured as an indicator of glycolytic capacity. Citrate synthase (CS), a Krebs cycle enzyme, was measured as an indicator of aerobic capacity. Malate dehydrogenase (MDH), an enzyme which helps maintain redox balance between the mitochondrion and cytosol, was also used as an indicator of aerobic capacity. When normalized to a common size, S. goodei, S. diploproa, S. alascanus and S. altivelis displayed an inter-specific pattern of declining metabolic activity with depth of occurrence. Intra-specific size scaling of glycolytic capacity (LDH) was positive in the shallow-living S. goodei. However, no scaling occurred in S. diploproa and S. alascanus, and negative scaling of glycolytic activity occurred in the deep-living S. altivelis. MDH did not scale in S. goodei and S. diploproa but was negative in the 2 deeper-living Sebastolobus species. CS activity scaled negatively in S. goodei, S. alascanus, and S. altivelis, but the deep-water specialist, S. altivelis, had the steepest slope. S. altivelis was the only species where similar-sized individuals could be compared over a wide depth range. There was no elevation of LDH, or increase in anaerobic poise, in response to the hypoxia of the OMZ. Rather, all 3 enzyme activities were highest at 600 m and generally declined with increasing depth. Contrary to the existing paradigm, S. alascanus and S. altivelis were not found to be shallow- and deep-living congeners. Rather, S. altivelis is a permanent resident of deep water, while S. alascanus settles in shallow water then migrates to deep water with the onset of sexual maturity. When living in deep water, the supposed shallow water species, S. alascanus, maintains higher activities of all enzymes and grows an order of magnitude larger (>5000 vs <500 g). In deep-water slope habitats expected patterns of allometric scaling of white muscle enzyme activities appear to be altered by the limitations of food and oxygen availability, a pattern previously observed in flatfishes.

The model was developed from experiments with gravel coated with crude oil and washed for 6 months. The modeled PAH included the 14 most persistent compounds of 31 analyzed by GC/MS. Parameters include loss-rate constants related to the energy required for PAH to escape from petroleum and a quantitative index of weathering. The model accounts for 91% of the temporal variability of modeled PAH concentrations. We compared the discrepancies between measured and model-predicted PAH concentrations of EVOS samples with a probability distribution of these discrepancies derived from the experimental weathering results. Only 1541 field samples contained sufficient PAH for valid application of the model; three-fourths fit the model at alpha greater than or equal to 0.01 type I error, 9% fit an alternate model characterized by the absence of weathering, 17% fit neither model, and a few fit both models. The 1164 total samples that fit the weathering model account for 86% of the summed PAH concentrations detected in all 7767 samples. We conclude that first-order loss-rate kinetics account for the dominant PAH weathering processes in the EVOS and that the rate of weathering is determined mainly by the ratio of surface area to volume of petroleum in the environment.

For each time-temperature treatment, 30 samples, each inoculated with an equal mixture of three strains of C. botulinum nonproteolytic type B, for a total of 10 super(7) spores, provided the basis for calculation of the thermal resistance (a 7D process). Following heat processing, the crabmeat was removed from the pouches and transferred to enrichment medium where it was incubated anaerobically for 150 days. Endpoints at which spores survived were determined by the presence of toxin in the enrichment medium. Process times ranged from 90 min at 88.9 degree C to 20.3 min at 94.4 degree C. D values (the time at each temperature required to reduce the inoculum by 1 log) ranged from 12.9 for the 88.9 degree C process to 2.9 for the 94.4 degree C process. The relative sterilization value, F sub(o), was .054 and the pasteurization value, F sub(1) super(1) sub(8) super(6) sub(5), was 240. This pasteurization process safely extends refrigerated shelf life by inactivating spores of Clostridium botulinum nonproteolytic types B, E, and F and also non-spore-forming pathogens such as Listeria monocytogenes. The process does not, however, inactivate the heat-resistant proteolytic strains of C. botulinum or other more heat-resistant spore-formers. The packages and master cartons of the pasteurized product, therefore, should be labeled "Keep refrigerated - Continuous refrigeration below 38 degree F (3.3 degree C) required."

The Industrial Source Complex (ISC2) model is a steady-state Gaussian plume model that is used for modeling point, area, volume, and line sources. Since its development in the 1970s by the U.S. Environmental Protection Agency, this widely used model has undergone several updates as state-of-the-science techniques have become available. Some of the recent modifications to the ISC2 model include a numerically efficient area-source algorithm tested in wind tunnel experiments, a dry-deposition algorithm that can account for a full range of particle size distributions, an algorithm for calculating wet-deposition flux using the scavenging coefficient approach, and an algorithm for modeling open-pit sources. These modifications, which are part of the current ISCST3 model, are described in detail within this paper. In addition, a plume depletion model demonstration was performed to compare observed and estimated-crosswind integrated concentrations of a depositing tracer as functions of travel time and stability.

N1 - Last updated - 2011-12-13 ER - TY - JOUR T1 - Improving concentration measures used for evaluating air quality models AN - 16253795; 4238565 AB - An unfortunate difficulty in model evaluation is that the concentration measure that most models predict, namely the ensemble mean concentration under the plume centerline (or at some location relative to the plume centerline), cannot be measured directly. The problem can be ameliorated by judicious selection of a concentration measure against which to compare model predictions. Insufficient attention has been given in the past to the selection of an appropriate measure for use in air quality model evaluation studies, which may have resulted in biases in the results of those studies. Some studies have used the maximum concentrations along the arc (arc maximum) as the measure of choice. In this paper, the authors have considered two additional candidate measures, the fitted maximum concentrations and the near-centerline concentrations, which, intuitively, relate more closely to the ensemble mean concentrations. This study shows that the maximum concentrations along the arc are significantly higher than either the fitted maxima or the near-centerline concentrations. In addition, of the latter two measures, the authors conclude that use of the near-centerline concentration is preferable to the use of fitted maximum for the purposes of evaluating model performance.

N1 - Last updated - 2011-12-13 ER - TY - JOUR T1 - The association of the population recruitment of Gulf menhaden, Brevoortia patronus, with Mississippi River discharge AN - 16243923; 4227446 AB - Gulf menhaden, Brevoortia patronus, which constitutes a major industrial reduction fishery in the USA, spawn across the northern Gulf of Mexico with a focus of spawning about the Mississippi Delta. This species is estuarine dependent; adults spawn over the continental shelf and their larvae are transported, by mechanisms that are presently not well understood, to estuarine nursery areas. Larval gulf menhaden, along with some other surface oriented larval fishes, appear to aggregate along the Mississippi River plume front, while evidence of the ecological consequences of this aggregation in terms of the feeding, growth, and survival of larvae is ambiguous. On an annual scale, Mississippi River discharge is negatively associated with numbers of half year old recruits. Discharge of the Mississippi River and the population recruitment of gulf menhaden may be plausibly linked through the action of the river's plume and its front on the shoreward transport of larvae. Greater river discharge results in an expansive plume that might project larvae farther offshore and prolong the shoreward transport of larvae. An indirect, decadal scale, positive response of recruitment and river discharge is possible, but not certain. Recruitment became elevated after 1975 when river discharge increased and became highly variable. This response might owe to enhanced primary and secondary production driven by nutrient influx from the Mississippi River. JF - Journal of Marine Systems AU - Govoni, J J AD - Natl. Mar. Fish.

There has been heightened interest in this subject recently due to the finding that high-elevation tropical glaciers have been retreating and that significant melting from even the highest alpine regions has occurred in some areas during the past 20 years or so, as recorded in ice core records, which do not reveal any similar period during previous centuries to millennia. In this paper we find evidence for appreciable differences in mean temperature changes with elevation during the last several decades of instrumental records. The signal appears to be more closely related to increases in daily minimum temperature than changes in the daily maximum. The changes in surface temperature vary spatially, with Europe (particularly western Europe), and parts of Asia displaying the strongest high altitude warming during the period of record. High-elevation climate records of long standing taken at a number of mountain tops throughout the world, but primarily in Europe, are available from a number of countries. In some cases, meteorological observations at these unique mountain sites have been discontinued for a variety of reasons, usually budgetary. It is hoped that the papers published in this special issue of Climatic Change can contribute to a reassessment of the value of continuing climate measurements at these mountain observatories by the appropriate entities, so that we may continue to have access to climate information from the 'tops of the world'.

Application to Human Protein C Secreted in Pig Milk AN - 807289847; 13858686 AB - Milk of transgenic pigs secreting recombinant human Protein C (rHPC) was used as a model system to determine the utility of aqueous two-phase extraction systems (ATPS) for the initial step in the purification of proteins from milk. The major challenges in purification of recombinant proteins from milk are removal of casein micelles (that foul processing equipment) and elimination of the host milk proteins from the final product. When milk was partitioned in ATPS composed of polyethylene glycol (PEG) and ammonium sulfate (AS), the phases were clarified and most of the caseins precipitated at the interphase. The partition coefficients of the major milk proteins and rHPC were dependent upon the molecular weight of the PEG used in the ATPS. Higher-partition coefficients of the major whey proteins, b-lactoglobulin, and a-lactalbumin were observed in ATPS made up of lower molecular-weight PEG (1000 or 1450) as compared to systems using higher molecular-weight PEG. Lowering the pH of the ATPS from 7.5 to 6.0 resulted in increased precipitation of the caseins and decreased their concentration in both phases. rHPC had a partition coefficient of 0.04 in a system composed of AS and PEG 1450. The rHPC in pig milk was shown to be highly heterogenous by two-dimensional gel electrophoresis. The heterogeneity was owing to inefficient proteolytic processing of the single chain to the heterodimeric form and differences in glycosylation and other post-translational processing. Differential partitioning of the multiple forms of purified rHPC in the ATPS was not observed. rHPC after processing in ATPS was recovered in a clear phase free of most major milk proteins. ATPS are useful as the initial processing step in the purification of recombinant proteins from milk because clarification and enrichment is combined in a single step.

During cruises in 1992 and 1994, samples were taken from the water column for trace metals, nutrients, dissolved gases, and particles near each of three basaltic outcrops overlying 3.5 m. y. old crust on the eastern flank of the Juan de Fuca Ridge in Cascadia Basin. The water column above one of these outcrops, Baby Bare, which rises about 70 m above a flat turbidite plain, was the most thoroughly sampled. Thermal, chemical (Mn, Fe, delta ( (super 3) He)%, CH (sub 4) , and O (sub 2) ), and particulate anomalies in the water column confirm the existence of (1) early diagenesis of organic matter in seafloor sediment which produces a flux of dissolved metals and nutrients to bottom seawater, (2) hydrothermal emissions which are both focused (spring-like) and diffuse, and (3) resuspension of sediment by turbulent flow of tidal currents about a topographical high. On the basis of data from the water column and thermal and chemical pore water data from 46 piston and gravity sediment cores near and on Baby Bare (FlankFlux 90 and 92), we constrain the composition of seawater in basement and thus the composition of spring-like water. Given this composition, no measurable dissolved silica or phosphate hydrothermal anomalies are expected in the water column.

A total of 3479 cloud-to-ground lightning flashes was composited with respect to times and locations of these flash floods. The analysis region was a square of 40 km on a side that nearly coincided with a small hydrologic region that drains runoff from high mountains around Tucson and results in streamflow near and through the city. Most lightning in the 40-km-square area occurred between 10 h before the flood and the reported time of the flood. Flashes were most frequent around 2 h prior to the flood, but advance timing was not consistent. The most important factor in determining whether a flash flood report followed lightning was the number of consecutive 5-min periods with two or more flashes in the 40-km-square area. Intensity of the maximum flash rate was not systematically related to the amount of flooding, except that the 2 days with highest lightning frequencies were associated with the most widespread flood effects of the summer in the Tucson area. No precursor was found in positive flashes. While lightning data identified many of the flash flood events and avoided most false detections, the sample size was very small and there were no other cases for an independent test. Streamflow increased abruptly after the occurrence of lightning for two flood periods on 19-20 July and another flood on 24 July. About 2 h after the maximum flash rate, streamflow gauges at three locations in the hydrologic region measured rapid rises in runoff that were indicative of the arrival of flash floods. Additional studies with flashes from an operational lightning detection network need to take into account additional factors, such as different locations, seasons, storm types, and precipitable water in low to midlevels, in order to more fully explore the possibility of lightning strikes providing useful precursors of flash flood events, particularly in rugged semiarid terrain.

A plume dynamics model provides the plume rise height, plume position, and the horizontal and vertical plume dispersions in the subgrid scale phase when the pollutants are to be simulated by the Lagrangian reactive plume module. A coupling exists between the models as the grid concentrations provide boundary conditions for entrainment to the subgrid plume sections, and a feedback ocurrs when the plume size and chemical criteria indicate a plume's pollutants are to be transferred to the grid system for further simulation. The methods for simulating the plume processes are also presented and the input/output data involved with these two components of the Models 3 plume-in-grid approach are discussed.

Prey consumption varies annually and accordingly with the physical and biological environment surrounding each island. Juvenile walleye pollock (Theragra chalcogramma) is the most common prey of northern fur seals from St. Paul Island; the island is surrounded by a broad neritic environment with widely separated frontal zones and is the greatest distance from the continental shelf-edge. Gonatid squid (Gonatopsis borealis/Berryteuthis magister and Gonatus madokai/Gonatus middendorffi) were the most common prey of northern fur seals from Medny Island; the island is surrounded by a compressed neritic environment and is adjacent to the continental shelf-edge and the oceanic marine environment. A combination of walleye pollock and gonatid squid is consumed by northern fur seals from St. George Island; the island has a surrounding oceanographic environment intermediate between the other two islands. Variability in predation on walleye pollock is consistent with fishery information concerning the relative abundance and availability of walleye pollock around St. George and St. Paul Islands. The abundance and availability of these prey resources during the summer breeding season are key factors which influence the health and growth of the northern fur seal populations in the Bering Sea.

The continental shelf off the west coast of Florida experiences frequent G. breve blooms (in 21 of the last 22 years) where the spatially explicit phases of G. breve blooms are closely coupled to physical processes. Bloom initiation occurs offshore and in association with shoreward movements of the Loop Current or spinoff eddies. A midshelf front maintained by seasonal wind reversals along the Florida west coast may serve as a growth and accumulation region for G. breve blooms and contribute to the reinoculation of nearshore waters. Local eddy circulation in the northeastern Gulf of Mexico and in the Dry Tortugas affects the retention and coastal distribution of blooms while the Florida Current and Gulf Stream transport cells out of the Gulf of Mexico and into the U.S. South Atlantic Bight. The causes of bloom dissipation are not well known but mixing or disruption of the water mass supporting G. breve cells, especially in combination with declining water temperatures, are important factors.

Here we report the results of an intercomparison among different methods used to determine free cupric ion concentration ([Cu super(2+)]) and organic complexation in lake water samples. The techniques used were potentiometric measurement with a cupric ion-selective electrode (Cu-ISE) and ligand exchange methods involving the addition of three well-characterized ligands with different binding affinities for copper (catechol, 8-hydroxyquinoline, and tropolone) followed by measurement of the Cu chelates of these ligands by adsorptive differential pulse cathodic stripping voltammetry (DPCSV). Good agreement was found among relationships between [Cu super(2+)] and the total concentration of natural copper species ([Cu sub(nat)]) determined via titration with the three ligand exchange/DPCSV methods. Relationships between [Cu super(2+)] and [Cu sub(nat)] measured by these methods also agreed with those determined with a cupric ion electrode within the overlapping range of detection windows for each method ([Cu sub(nat)] = 40-100 nM). At lower Cu concentrations, the Cu electrode gave erroneously high [Cu super(2+)] readings, apparently due to a failure of the electrode membrane to equilibrate with the sample. The agreement among the different methods provides support for the validity of each individual method of measuring [Cu super(2+)] and natural Cu complexation. By combining Cu titration data measured by DPCSV and Cu-ISE, we obtained a more complete description of the Cu-complexing characteristics of water samples from two Swiss lakes than could be obtained with any single method. Equilibrium modeling of this composite data indicated the presence of at least three ligand classes. These ranged in concentration from 38 plus or minus 19 nM for the strongest binding ligand class, which had conditional binding constants in the range of 10 super(15) at pH 7.8-8.0, to 8 plus or minus 2 mu M for the weakest class of ligands, which had a conditional constant of 10 super(8.6) M super(-1).

Species of interest were Brevoortia, tyrannus, Lagodon rhomboides, Leiostomus xanthurus, Micropogonias undulatus, Mugil cephalus, Paralichthys albigutta, P. dentatus, and P. lethostigma. Our data suggest that sampling at intervals >7 days can lead to excessive variance in abundance estimates. For all species, abundance varied as much as an order of magnitude from night to night. Proportional residuals from polynomial models of the seasonal recruitment pattern for a given species were used to assess the potential influence of nine environmental variables on daily densities. Twenty-seven of 72 correlations of proportional residuals with environmental variables were significant (P<0.05). Proportional residuals were positively correlated with time after dusk for six of eight species and were negatively correlated with turbidity for five of eight species. However, interpretation of correlations must be done cautiously because a species' recruitment pattern may coincide with normal seasonal change in one or more environmental variables. Variability in transport of larvae, from offshore to near the inlet and then through the inlet to the station, probably influences species abundance at the sampling station more than locally acting environmental variables. Daily collections of B. tyrannus larvae provided otoliths (n=1,341) showing that a large number of younger larvae, averaging 55 days posthatch, arrived at the station in mid-March on the date of maximum observed daily density (160 larvae per 100 m super(3)).

Yellowfin sole sampled during spring and summer bottom trawl surveys (1982-94) grew faster in the northwest area compared with the southeast area. Mean lengths at age were generally more than 2 cm greater than those for southeast fish at ages greater than 10 years. Length at 50% maturity in females during 1993 and 1994 was respectively 2.3 cm and 0.94 cm larger in the northwest area than in the southeast area. In contrast, there was no apparent difference in age at 50% maturity between areas. Spring-summer patterns in bathymetric habitation of yellowfin sole differ for immature and mature individuals and cause a potential bias in estimates of growth and maturity. There is a clear relation between length and depth for immature fish, with older, immature fish inhabiting deeper water. In contrast, mature fish distribute similarly by size across a wide range of bottom depths. As a result, estimates of length and age at 50% maturity (L sub(50), A sub(50)) tended to increase with increasing bottom depth. Because current resource assessment surveys do not sample the shallowest areas of the summer distribution of yellowfin sole, estimates of L sub(50) and A sub(50) are inherently biased high.

Jet injection does not affect survival or growth of juvenile salmonids in the laboratory but may contribute to increased mortality in field situations. Injection by Panjet has been used primarily on freshwater fish species in addition to salmonids. Juvenile flatfish have been marked with needle-injected latex as well as by freeze branding, but not by jet injection. To our knowledge, juvenile sablefish have been marked only with Floy anchor tags. Our objectives were to evaluate retention of jet-injected marks and their effect on growth of four marine fish species, as well as their effect on the tissue structure of three marine species held in the laboratory. We tested the retention of jet-injected marks and effects of marks on growth of four species of marine fish and histological effects on three species of marine flatfish.

Nighttime flows out of the valleys had low O sub(3) concentrations, according to surface measurements, and also had low aerosol concentrations, as measured by a scanning Doppler lidar. Analysis of lidar scan data showed that the flows were highly complex, that the relatively clean flow was confined to the lower levels (lowest similar to 500 m) of the valley, and that regions of strongest outflow were also the regions of "cleanest" air. Measurements of NO sub(2) concentrations well above background levels in the outflow indicate that it was formerly polluted air from which O sub(3) and aerosols had been removed. Possible removal mechanisms were found to be dry deposition in the katabatic (downslope) flows down the valley sidewalls, in agreement with a previous study in a Swiss valley, or fast chemical reactions with NO and NO sub(3). Nearly horizontal lidar scans showed that the valley exit flows penetrated into the LFV, where they merged with the downvalley/land-breeze system along the Fraser River.

AN - 16057916; 4105833 AB - The controls on metal concentrations in a plume of acidic (pH 3.29-5.55) groundwater in the Moon Creek watershed in Idaho, U.S.A., were investigated with the use of property-property plots. A plot of Ca vs S demonstrated that a plume of contaminated groundwater was being diluted by infiltration of rain and creek water at shallow depths and by ambient groundwater near bedrock. The small amount of dissolved Fe (2.1 mg/l) was removed while dissolved Pb was added, reaching a maximum concentration of 0.37 mg /l. The other metals (Zn less than or equal to 16, Al less than or equal to 6.2, Cu less than or equal to 2.1 and Cd less than or equal to 0.077 mg/l) in the shallow groundwater were essentially conserved until they emerged as a seep along the creek bank. Upon mixing with the creek water, groundwater was diluted by factors between 11 and 50, and the pH of the mixture became neutral. Metals originating from the contaminated groundwater were removed in the creek in the following order: Fe > Al > Pb >> Cu > Mn > Zn = Cd. Pb and Cu continued to be removed from solution even as the creek passed adjacent to a tailings pile. In contrast, Zn concentrations in the creek increased adjacent to the tailings area, presumably as a result of the reemergence of the upgradient plume as the creek lost elevation. Below the tailings dam, contaminated creek water (400-800 mu g Zn/l) was diluted by both smaller side streams and a creek of equal flow. The presence of 3 distinctive water masses required the use of two tracers (dissolved Si and S) to distinguish between mixing and geochemical reactions. The removal of metals was greater during low flow conditions. Pb was removed to the greatest extent, falling below detection limits (0.5 mu g/l) at the first sampling location. Copper and Mn were removed to a lesser extent during low flow conditions and approached conservative behavior during high flow conditions. During a 5-km journey through two hydrological regimes, less than 10% of the dissolved Zn and Cd was lost. JF - Applied Geochemistry AU - Paulson, A J AD - Analytical and Environ. Chem.

Three of the minimum population thresholds are derived from virtual population analysis. Recent substantial inconsistencies in estimates of management variables have led to errors in stock abundance estimates. While all the methods used to estimate fully recruited fishing mortality in terminal years were imprecise, conventional catch-curve estimates were unbiased and had the least retrospective inconsistency. Retrospective differences in recruitment, spawning stock biomass, and spawning potential were skewed positively but not biased. The skewed distribution of retrospective inconsistency should be taken into consideration in managing the Atlantic menhaden fishery.

The Authement-Ledet excluder, Cameron Shooter, and Lake Arthur excluder devices caught fewer fish but also fewer shrimp compared with control nets not using BRDs. The Eymard accelerator caught higher fish numbers but less biomass and more shrimp (numbers and biomass) compared with control nets. The differences between BRD and control net catches was dependent on the type of organisms occurring in the trawl area. BRD selection should take into account the organisms present in the area.

AN - 16352794; 6469 AB - PURPOSE: The disposal and reuse of McClellan Air Force Base (AFB) in Sacramento County, California, is proposed. McClellan AFB, which comprises 3,000 acres, is located in the Sacramento Valley, bounded on the east by the Sierra Nevada and on the west by the Pacific Coast and Diablo range. The base, which was established in 1936 and is scheduled for closure in the year 2001, consists of the main AFB (2,856 acres), Capehart Housing (217 acres), Sacramento River Dock (2 acres), Camp Kohler (35 acres), the Hospital Annex (26 acres), and Davis Global Communications Site (316 acres). All properties would be available for civilian reuse except for some properties that would be retained for military and federal agency uses: Camp Kohler, the Hospital Annex, 120 acres of the Davis Site, and 39 acres of Capehart Housing. Five alternatives, including a No Action Alternative, are considered in this final EIS. Under the proposed action, a technology center would be established within the industrial core of McClellan AFB with a private airfield to be operated as part of the industrial infrastructure. By the year 2020, the airfield would support 5,050 takeoffs and landings. The center would include a high-technology industrial park with aircraft maintenance and related industrial operations, office and administrative areas, housing and community support, and warehouse and logistics. POSITIVE IMPACTS: In general, the redevelopment would provide for aviation-related, commercial, educational, and recreational use of the land in agreement with the community's reuse plan. By the year 2020, the proposed action would support 16,100 direct jobs and 15,900 secondary jobs, representing a net employment increase of 7,600. NEGATIVE IMPACTS: The construction activities would result in short-term increases in erosion and water quality impacts; the permanent loss of wetlands, riparian woodlands, and native trees; and the alternation or degradation of the Sacramento Air Depot Historic District.

AN - 16351213; 6468 AB - PURPOSE: The implementation of harvesting regulations for weakfish in the exclusive economic zone (EEZ) along the Atlantic Coast is proposed. At present, there are no federal regulations in effect on the harvest or possession of weakfish along the Atlantic Coast. The weakfish stock is continuing to decline, and the 1993 stock assessment showed signs of recruitment failure. During 1991-1994, some 80 percent of the population was harvested annually and only five percent of the population achieved spawning age. Total landings have declined from 80 million pounds in 1980 to 7.9 million pounds in 1994. Five alternatives, including a No Action Alternative (Alternative E), are considered in this final supplement to the final EIS of September 1995. The preferred alternative (Alternative D) would apply federal regulations in the Atlantic Coast EEZ compatible with the effective implementation of the Atlantic States Marine Fisheries Commission's interstate fishery management plan for weakfish. It would implement a 12-inch total length minimum size for fish taken in the EEZ. It would also require that weakfish harvested commercially in the EEZ be landed only in the following states: Massachusetts through North Carolina (except Pennsylvania), and Florida and in accordance with the states' landing laws. It would also require minimum mesh sizes in the EEZ be consistent with a 12-inch minimum fish size: 3.25-inch square stretch mesh or 3.75-inch diamond stretch mesh for trawls, and 2.875-inch stretch mesh for gillnets. It would also require that non-directed fisheries coastwide using smaller mesh sizes than that consistent with a 12-inch minimum fish size could possess no more than 150 pounds of weakfish bycatch in any one day or trip, which ever were longest. The use of flynets in the EEZ south of Cape Hatteras would be prohibited. In February 1996, a federal district court ruled that amended fishery management plan (FMP) presented in the final EIS was not a valid FMP because it did not contain management recommendations for the Secretary of Commerce. This final supplement includes those recommendations. POSITIVE IMPACTS: The imposition of the restrictions would stabilize the fishery, restore the stock to satisfactory levels, and protect juvenile weakfish. NEGATIVE IMPACTS: An increase in weakfish flynet operations north of Cape Hatteras could adversely affect marine mammals and sea turtles.

AN - 79145251; 9228736 AB - A thermodynamic investigation of the hydrolysis and cyclization reactions of cyclomaltohexa-, hepta-, and octa-ose (alpha-, beta-, and gamma-cyclodextrins) has been performed using microcalorimetry and high-performance liquid-chromatography. The calorimetric measurements lead to standard molar enthalpy changes delta rHm0 (T = 298.15 K, KH2PO4 buffer (m = 0.10 mol kg-1), pH = 4.58 to 5.15) for the following reactions: alpha-cyclodextrin(aq) + 6H2O(l) = 6 D-glucose(aq), beta-cyclodextrin(aq) + 7H2O(l) = 7 D-glucose(aq), gamma-cyclodextrin(aq) + 8H2O(l) = 8 D-glucose(aq). Equilibrium constants were determined for the following generalized cyclization reactions (T = 329.6 K, 0.005 mol kg-1 K2HPO4 buffer adjusted to pH = 5.55 with H3PO4) catalyzed by cyclomaltodextrin glucanotransferase: Gu(aq) = alpha-cyclodextrin(aq) + G(u-6)(aq), Gv(aq) = beta-cyclodextrin(aq) + G(v-7)(aq), Gw(aq) = gamma-cyclodextrin(aq) + G(w-8)(aq). Here, G1 is D-glucose and the Gn's (n is a positive integer) are linear maltodextrins; u, v, and w are, respectively, integers > or = 7, > or = 8, and > or = 9. Values of the equilibrium constants, standard molar Gibbs energy change delta rGm0, standard molar enthalpy change delta rHm0, standard molar entropy change delta rSm0, and standard molar heat-capacity change delta rCp,m0 are tabulated for the above reactions at T = 298.15 K. The values of delta rGm0 and delta rSm0 for the first three above-mentioned reactions rely upon an estimated value of delta rSm0 for the hydrolysis reaction of maltose to D-glucose. The thermodynamics of the disproportionation reaction Gm(aq) + Gn(aq) = Gm-1(aq) + Gn+1(aq) is also discussed.

AN - 36414460; 6437 AB - PURPOSE: The designation of Monterey Bay and its adjacent waters, and the submerged lands thereunder, off central California, as a national marine sanctuary is proposed. Under the preferred boundary alternative, the sanctuary would encompass an area of approximately 4,024 square nautical miles in and surrounding Monterey Bay, and extend along 362 nautical miles of shoreline. Federal and state waters would account for 83 percent and 17 percent, respectively, of the proposed sanctuary. The northern terminus of the sanctuary boundaries would be located along the southern boundary of the Gulf of Farallones National Marine Sanctuary and run westward to approximately the 500 fathom isobath. The boundary line would then extend southward in an arc, following the 500 fathom isobath to a point due west of Cambria. The boundary line would then extend shoreward toward the mean high-water line. The landward boundary would be defined by the mean high-water line between the Gulf of Farallones National Marine Sanctuary and Cambria, exclusive of a 71-square-mile area off the north coast of San Mateo County and the city and county of San Francisco, between Point San Pedro and Point Bonita. Under the preferred alternative, new regulations would be promulgated to govern hydrocarbon activities; discharges and deposits; overflights by low-flying aircraft; alteration of or construction on the seabed; historical resources; marine mammals, turtles, and seabirds; and personal water craft. To aid in the enforcement of these regulations, additional regulations have been proposed that would prohibit the possession of resources and the interference with enforcement efforts. This draft EIS to the final EIS of June 1992 would amend the regulations to allow limited, small-scale jade collection within the sanctuary boundaries. The Jade Cove area consists of a series of small coves located south of Big Sur, near Gorda, California. Jade occurs in veins in the serpentine bedrock formation, extending from inland mountains, down the cliffs and into the seabed. Three alternatives, including a No Action Alternative, are considered in this draft supplement. The preferred alternative would restrict collection efforts to loose jade broken loose from the seabed by natural action. The other action alternative would permit unrestricted collection of jade. POSITIVE IMPACTS: The designation of the Monterey Bay area as a national marine sanctuary would provide for an integrated program of resource protection, research, and education. Resource protection would involve cooperation with other agencies to assure appropriate implementation of policies and procedures. Through education, public awareness of the value of this area would be enhanced. Sanctuary management would result in the maintenance or improvement of the water quality, fishery resources, and aesthetics of the area. The regulatory amendment affecting jade collection would ensure that the resource is not depleted. NEGATIVE IMPACTS: Permit, license, and lease costs would adversely affect local users of the sanctuary. Regulations covering discharges and deposits could result in more substantial cost increases for users. Revenue associated with oil, gas, and mineral activities, all of which would be prohibited under the management plan, would be foregone. Modest increases in tourism would result from the proposed regulatory amendment on jade collecting. LEGAL MANDATES: Marine Protection, Research, and Sanctuaries Act of 1972, as amended (33 U.S.C. 1401 et seq.).

Osmoregulatory ability of infected fish was better after acclimation in 10ppt salinity water before transfer to 30ppt, salinity water. Infected fish exercised overnight (3.0 body lengths/s) were unable to survive the seawater challenge, whereas uninfected fish similarly exercised survived with the same plasma Na super(+) levels as unexercised fish. Because BKD is present in most salmonid stocks, stress of seawater transfers should be minimized through acclimation and reduced exertion.

Non-tidal ocean loading induces changes in oceanic bottom pressure, which in turn deform the geoid and the nearby crust. Changes in the bottom pressure are derived from estimates of sea-surface height variability and density changes output from an oceanic general circulation model. Sea surface heights measured by the TOPEX/POSEIDON altimeter are also used to infer changes in bottom pressure. We estimate than non-tidal ocean loading can typically cause nearly equal 5 mm of peak-to-peak (2 mm root-mean-square, rms) vertical motion at sites near the shore, with displacements of up to 10 mm possible. Amplitudes of horizontal displacements are about one-third those of vertical ones. Deformation-associated gravity changes are usually of the order of 2-3 mu Gal; however, peak-to-peak changes of 5 mu Gal are also predicted. Loading-induced geoid perturbations in mid-ocea regions are typically 5-10 mm peak-to-peak (3 mm rms) and can extend over a region of 20 degrees . In the case of atmospheric loading of the oceans, we estimate the difference between the inverted barometer correction, usually used to describe the ocean's response to atmospheric pressure, and the complete equilibrium response. There are two sources of this difference. One is that the inverted barometer correction does not conserve oceanic mass. We use National Meteorological Center (NMC) global pressure data to estimate the time-dependent, average change in pressure over the oceans. A time-series of the net pressure over the oceans contains an annual signal with a peak-to-peak amplitude of 1.2 mbar superimposed on a linear trend of 0.09 mbar yr (super -1) . The secular signal is caused by a redistribution of atmospheric mass from over continental land masses to the oceans. We conclude that this effect introduces additional variability into the ocean's response to pressure at annual, secular, and multi-year timescales, with a total peak-to-peak amplitude of a few tens of millimetres. The second difference between the inverted barometer response and the complete equilibrium response is due to gravitational forcing by the atmosphere and by the displaced mass in the solid Earth and oceans caused by the atmospheric loading. This effect is largest within about 1000 km of the coast and at high latitudes. We use NMC pressure data to estimate the effect, and find that it causes differences from the inverted barometer solution in those regions of up to 10-30 mm peak-to-peak, with values as large as 50-60 mm possible at certain locations. The time dependence of this effect is negatively correlated with the inverted barometer response. The effect causes an apparent reduction of the inverted barometer response by a few per cent within a few hundred kilometres of the coast, with reductions of more than 6-7 per cent at a few places.

Laminated, high deposition rate sediments of the Cariaco Basin, a small anoxic basin on the Venezuelan continental shelf, clearly record large changes in the past intensity of this upwelling. Because sediments of the Cariaco Basin are largely unbioturbated, they offer a natural opportunity to study the stable isotopic records of multiple planktonic foraminiferal taxa and to evaluate their sensitivity to both the modern hydrography and temporal changes in upwelling intensity and climate. Oxygen isotope data (delta (super 18) O) from four dominant foraminiferal taxa are presented for the time period covering the last 28 kyr. The delta (super 18) O data from Globigerina bulloides, after correction for nonequilibrium precipitation, are used as a monitor of sea surface conditions during the winter-spring upwelling season. The delta (super 18) O data from white Globigerinoides ruber are used as a measure of annual-average conditions in the near surface, while pink G. ruber data are consistent with use as an index of endmember conditions during the summer-fall nonupwelling season. Data from the deeper dwelling Neogloboquadrina dutertrei yield information on conditions near the base of the local thermocline. During the last glacial, delta (super 18) O data from G. ruber and generally reduced interspecific differences indicate cooling of surface waters over the Cariaco Basin by up to 4 degrees C. This longer-term cooling does not appear to be related to changes in upwelling intensity along the coast but may instead reflect more regional cooling of the larger Caribbean. Superimposed on this pattern, between 12.6 and approximately 10 ka, is a convergence of delta (super 18) O data between G. bulloides and N. dutertrei, implying much stronger upwelling during the last deglaciation. This scenario is consistent with other evidence for high productivity at this time. At approximately 14 ka, a sharp delta (super 18) O depletion event observed in all taxa seems to have been produced by increased freshwater discharge to the southern Caribbean, suggesting either higher regional rainfall or the influence of glacial melting in the Andes. Minimum delta (super 18) O values of pink G. ruber around 6-7 ka record warmer summer sea surface temperatures and/or decreased salinity in the mid-Holocene.

Comparisons with the in situ measurements of median radius and number density are favorable only if the 10.59-mu m backscatter is doubled, indicating a calibration bias in NOAA's climatological data set.

These extreme values are the largest recorded in Japan this century and are among the highest ever documented for non-landslide generated tsunamis. We model this event to confirm the estimated overland flow velocities, and we find that, given reasonable ground deformation data, current state-of-the-art shallow-water wave models can predict tsunami inundation correctly including extreme runup, current velocities and overland flow. We find that even small local topographic structures affect the runup to first-order, and that the resolution of the bathymetric data is more important than the grid resolution. Our results qualitatively suggest that -for this event- coastal inundation is more correlated with inundation velocities than with inundation heights, explaining also why threshold-type modeling has substantially underpredicted coastal inundation for this and other recent events.

The measurements were performed with the NOAA Environmental Technology Laboratory instrumentation. The observed ice clouds were mostly cirrus clouds located in the upper troposphere above 5.6 km. Their geometrical thicknesses varied from a few hundred meters to 3 km. Characteristic cloud particle sizes expressed in median mass diameters of equal-volume spheres varied from about 25 km to more than 400 km. Typically, characteristic particle sizes were increasing toward the cloud base, with the exception of the lowest range gates where particles were quickly sublimating. Highest particle concentrations were usually observed near the cloud tops. The vertical variability of particle sizes inside an individual cloud could reach one order of magnitude. The standard deviation of the mean profile for a typical cloud is usually factor of 2 or 3 smaller than mean values of particle characteristic size. Typical values of retrieved cloud ice water content varied from 1 to 100 mg m super(-3[/supscript]; however, individual variations were as high as four orders of magnitude. There was no consistent pattern in the vertical distribution of ice water content except for the rapid decrease in the vicinity of the cloud base. The relationships between retrieved cloud parameters and measured radar reflectivities were considered. The uncertainty of estimating cloud parameters from the power-law regressions is discussed. The parameters of these regressions varied from cloud to cloud and were comparable to the parameters in corresponding regressions obtained from direct particle sampling in other experiments. Relationships between cloud microphysical parameters and reflectivity can vary even for the same observational case. The variability diminishes if stronger reflectivities are considered. A procedure of 'tuning' cloud microphysics-reflectivity regressions for individual profiles is suggested. Such a procedure can simplify the radar-radiometer method and make it applicable for a broader range of clouds.)

This paper shows that there are significant errors in mean vertical velocities measured by the vertical beam of 915-MHz wind profilers. The erroneous velocities are 0.1-0.3 m s super(-1) downward in daytime convective boundary layers over two sites, flat farmland in Illinois and rolling forest in Wisconsin. Velocities at night are not affected, and different days have different erroneous velocities. The directly measured velocities are compared to vertical velocities calculated from the divergence of the horizontal wind to show that they are indeed in error. The erroneous velocities are not caused by detectable rain, by an error in the beam pointing direction, or by the skewness of the vertical velocity distribution. They are probably due to small targets (particulate scatterers) that have a small fall velocity and are detected by the radar. An online algorithm for removing intermittent contamination reduces the error, but does not eliminate it. The fluctuating component of the velocity is not affected by these errors since it is much larger in magnitude.

N1 - Last updated - 2015-03-24 ER - TY - JOUR T1 - The Integration of Trajectory Models and Analysis into Spill Response Information Systems AN - 17092807; 4405032 AB - The spill response community is engaged in a technological rush towards computer-based, information-synthesis systems. Typically, they are modeled after many successful 'incident command' or 'command and control' systems that rely on micro- or mini-computer technology that is friendly and graphically oriented. Virtually all of these systems offer spill trajectory modeling components. What is typically lacking in this modeling output is any reliable way to estimate the uncertainty. This means that advice derived from the models is of questionable value, and when integrated into a complex response plan, the propagation of errors could seriously compromise the usefulness of results. It is shown that no single trajectory model run can provide the necessary information to respond in an optimal, 'minimum regret' strategy. However, a well-defined series of model runs used as the basis for trajectory analysis can provide the required information. A discussion of options suggests that the adoption of a minimum standard analysis procedure would significantly improve the ability of integrated response systems to use the predictions of oil distributions.

The minimum temperature required for inactivation of L. monocytogenes was 153 degree F (67.2 degree C) when generated smoke was applied throughout the entire process. When generated smoke was added only during the last half of the process, L. monocytogenes was recovered from steaks heated to temperatures as high as 176 degree F (80.0 degree C). When smoke was not applied during the process, L. monocytogenes survived on steaks heated to internal temperatures between 131 degree F and 181 degree F (55.0 to 82.8 degree C) but was not isolated from steaks heated above 181 degree F (82.8 degree C). When liquid smoke CharSol C-10 was applied as a full-strength (100%) dip before processing, L. monocytogenes was inactivated in samples processed at temperatures as low as 138 degree F (58.9 degree C). When liquid smoke 10-Poly or CharSol C-10 was applied at a concentration of 50%, the lethal temperature was increased to the range of 145 to 150 degree F (62.8 to 65.6 degree C). With further dilution of C-10 to 25% and 10% the inactivation temperatures increased to 156 degree F (68.9 degree C) and 163 degree F (72.8 degree C). A full-strength dip of CharOil, the oil-soluble fraction of CharSol C-10, was less effective, and L. monocytogenes survived in salmon steaks processed to an internal temperature of 166 degree F (74.4 degree C), the highest temperature tested with this liquid smoke. This study provides evidence that heat alone is not reliable for inactivation of L. monocytogenes during the hot-smoking process. The proper stage and duration of smoke application or proper composition and concentration of liquid smoke in combination with heat are critical for inactivation of the organism.

The measured emissions were 1.3 x 10 super(3) metric tons (C) hour super(-1) (11.4 x 10 super(6) metric tons (C) year super(-1)), six times greater than the combustion emissions assumed by Jaffe and coworkers in J. Atmos. Chem. 20 (1995), 213-227, based on 1989 reported Prodhoe Bay oil facility fuel consumption data, and four times greater than the total C emissions reported by the oil facilities for the same months as the measurement time periods. Variations in the emissions were estimated by extrapolating the observed emissions at a single altitude for all tundra research transect flights conducted downwind of the oil fields. These 30 flights yielded an average emission rate of 1.02 x 10 super(3) metric tons (C) hour super(-1) with a standard deviation of 0.33 x 10 super(3).

The parasite appears to be identical to one first reported by Victor Loosanoff over 40 years ago in larvae of several bivalve species. Named Sirolpidium zoophthorum by H. S. Vishniac in 1955, it belongs to a small group of primitive marine fungi in the order Lagenidiales. The parasite develops within the soft tissues of the larvae eventually absorbing the entire body. Fully developed thalli of the fungus appear as spherical bodies or sparsely branched tubes. The highly vacuolated multinucleate cytoplasm of mature thalli produce biflagellate zoospores by progressive cleavage. At first, these vigorously swimming cells can be seen actively milling about in the parent cell, later emerging through specialized exit tubes. Infection of healthy bivalve larvae has not been directly observed, but comparison with events recorded for other invertebrate hosts suggests that infection is initiated by the attachment of one or more zoospore to the body wall. So far, there is no evidence of ingestion of the zoospores as a route of infection. Resistance to the parasite is unknown. Infected larvae are doomed. The importance of this parasite in the health and survival of hatchery-spawned bay scallops is discussed.

Spawning of field-collected adult tautog was accomplished under laboratory conditions. Tautog allowed to spawn naturally produced more viable embryos than those spawned artificially. Eggs were collected and placed in 250-micron mesh bags held in flowing-ambient-temperature seawater where hatching occurred within 48 hours. Yolk-sac larvae were transferred to round 4 ft tanks of static sand-filtered seawater where they were fed protozoans for 4-6 days post-hatch, followed by rotifers from days 2 to 20 post-hatch and brine shrimp from day 7 to several months post-hatch. Utex, an alga high in fatty acid content, was added to the tanks to enrich the prey items, hence the term green-water culture. Slow flow-through green-water culture proved superior to static methods of culture. Flowing water prevented build-up of waste products and maintained high water quality. The young larvae were very sensitive and handling resulted in high larval mortality. Tautog were cultured in the green-water tanks until ambient seawater temperatures began to decline. The fish were moved indoors to recirculating seawater tanks at 3-months old and were weaned onto a diet of chopped mussel, clam, and a commercial food.

The building itself is 30' x 32' with a galvanized pipe frame and a transparent covering. There are two 4,700 gallon (17,150 liter) oval culture tanks placed two feet into the gravel floor and eight 137 gallon (500 liter) cylindrical culture tubes along the north wall. Solar illumination can be supplemented with twelve 1,000 W sodium vapor lamps suspended over the oval tanks and fluorescent fixtures behind the cylindrical tanks. Underground pipe-chases connect the greenhouse to the laboratory's "tank farm" building housing animals to be fed. Maximum production should be able to exceed 5,000 gallons (18,250 liters) per day of dense algal suspension. The research effort in this facility will focus upon the application of industrial process-control technology to phytoplankton culture for aquaculture feeds. We have designed and are assembling computer-controlled, automated systems to minimize labor while increasing flexibility and accuracy. Ultimately this research will allow increased production and reduce the cost of large-scale algal culture.

Tautog are a popular recreational species valued for their mild flavor and white-flaked texture. An Asian seafood market exists for 1 pound or "wok sized" fish. Depleted natural stocks could potentially be enhanced by releasing cultured fish back into the environment. Studies over the last two years at the Milford Laboratory have resulted in culture of tautog to 1.5 years old and suggest that tautog aquaculture may be feasible. Adult tautog were allowed to spawn naturally in long raceway tanks. Eggs were collected and placed in 250-micron mesh bags held in a Styrofoam float in flowing, ambient-temperature seawater where they hatched within 48 hours. Yolk-sac larvae were transferred to green-water culture tanks which were stocked with protozoans and rotifers for the tautog to prey upon. These prey items were fed an alga high in fatty acid content to provide an enriched high quality food for the tautog. Brine shrimp nauplii, and eventually adults, were introduced later to provide larger size prey. Daily monitoring of tank conditions indicated that static culture beyond a few weeks duration resulted in elevated ammonia concentrations and reduced water quality. Therefore, flowing seawater was added to the tanks at a slow rate once the yolk-sac was resorbed, approximately 6 days post-hatch. At this time, the fish had acquired pigment and were observed actively feeding in the water column. Slow flow-through green-water culture kept concentrations of ammonia and other wastes in the tanks at low levels, but allowed food items to be retained long enough to allow adequate feeding. Tautog larvae proved to be very sensitive to handling for the first month or two post-hatch. When ambient water temperatures declined, three-month-old cultured tautog were transferred to recirculating seawater tanks at room temperature to promote year-round growth. Fish were weaned onto an artificial diet, supplemented with chopped mussel and clam. The goal for potential aquaculture of tautog is growth from larvae to 1 pound or "wok" size within a two-year period. Work at the Milford Laboratory continues to refine culture methods to determine whether tautog would be a good candidate for finfish aquaculture and enhancement of wild stocks.

Moreover, success achieved with the selective breeding of oysters from Long Island Sound for fast growth has increased the expectation that other shellfish, in particular scallops, can similarly be improved. To investigate heritable responses to selection for growth of bay scallops (Argopecten irradians) from Long Island Sound, wild native bay scallops from Stonington, Connecticut were mass-spawned in 1995 to establish four genetic lines for selective breeding. Progeny were cultured and grown to maturity. The following year, the fastest growers or largest animals were selected and spawned to produce a subsequent generation. Concurrent selection was performed for the slowest growers or smallest specimens as controls for determining whether differences in size between groups could be attributed to genetic selection. Variations in early growth responses were observed among the first selected generation lines of scallops. Explanations for these results are discussed.

We also compared catch per unit effort for each harvest treatment in order to evaluate economic efficiency. In order to mimic the effect of an actual harvest season, professional oyster fisherman were employed to conduct harvest treatments and replicate experimental reefs were harvested until no further returns were made. Reefs harvested with dredges experienced the greatest reduction of reef height (-29 plus or minus 12 cm) and highest sedimentation rates compared to other treatments. Incidental mortality was lowest and catch per unit effort was highest on reefs that were harvested by divers. Alteration of the physical structure of oyster reefs caused by harvest disturbance has important ecological implications because reef height controls local hydrodynamic flow, which, in turn, influences recruitment, growth, and survival of oysters. Long-term production of oysters and other ecosystem services performed by oyster reefs are also controlled by interaction between harvest-related reef degradation and reduced estuarine water quality. Our results provide further evidence for why management of oysters and their reef habitat should be transferred from fisheries to ecosystem managers.

Activities supported by grant programs administered by the National Marine Fisheries Service have emphasized cost-effective approaches for advancing environmentally-sound private aquaculture development, feasibility of aquaculture as an enhancement tool for rebuilding overexploited finfish and shellfish populations, and its potential in providing new business opportunities for displaced fishermen. This emphasis is succeeding in building new partnerships among the public, private, and academic sectors and has begun to answer important questions concerning culture technology, system design, and economic viability. Recent experiences have further focused attention on the time-consuming logistics of permitting requirements for aquaculture operations at the local, state, and federal levels. Activities are also addressing the implications of known and potential environmental impacts and market uncertainties. Increased financial support for aquaculture is serving as a catalyst for dealing with technical, political, and managerial concerns which otherwise would have surfaced over a more extended horizon. The ultimate success in their resolution will be dependent upon the further assessment, likely from a geo-political perspective, of aquaculture as it relates to sustainable economic development and resource stewardship responsibilities among local, state, and federal jurisdictions. The prognosis continues to be one of guarded optimism. (DBO) JF - Journal of Shellfish Research AU - Mears, H C AD - USDOC, NOAA, Natl. Mar. Fish.

To follow up on this observation, we conducted several experiments to explore potential practical applications of this algal strain as a component of larval feeding regimes designed to induce metamorphosis at the convenience of the hatchery operator. In one experiment, we compared growth and days-until-metamorphosis in larval scallops switched from a unialgal diet of T-ISO to a unialgal diet of CCMP459 on days 4, 5, 6, 7, or 8. The dietary switch on day 6 resulted in metamorphosis on days 8-9 and was considered most promising. In a subsequent experiment, we sought to determine the smallest portion of the T-ISO diet we would need to replace with CCMP459 on day 6 for effective induction of metamorphosis (10, 25, 50, 75, and 100% were tested). The rationale for this experiment was that CCMP459 is relatively difficult to culture. Percentages less than 75% resulted in slower growth and later metamorphosis than diets with 75 or 100%; therefore, a switch to 75% CCMP459 + 25% T-ISO on day 6 was considered to be the optimal larval feeding regime to induce early metamorphosis. The final experiment was designed to determine whether or not viable post-set scallops were produced using the experimental feeding regime of T-ISO, changing to 75% CCMP459 + 25% T-ISO on day 6, as compared with a unialgal larval diet of T-ISO. As post-set scallops rapidly lose the ability to filter small cells, such as CCMP459, all scallops were switched to a diet of Tetraselmis striata, strain PLAT-P, when metamorphosis was first observed. On day 29 of life (about 20 days after metamorphosis), living post-set scallops (ca. 1 mm) were counted. Approximately 1,500 post-set were recovered from a pre-set population of 400,000 on the experimental feeding regime (only about 0.3%), but this was six times the number recovered (250) from the T-ISO-only regime. Reasons for overall poor setting success probably were related to sub-optimal conditions in the 10-liter buckets employed (temperatures 18-20 degree C, poor setting surface, and fouling of bucket sides after setting). Nevertheless, we are encouraged by the relative success of the experimental feeding regime and intend to test it in 400-liter conical tanks in collaboration with other Milford programs.

Our work includes: 1) laboratory culture and experimentation; 2) development and application of biochemical and molecular indices of physiological status; and 3) field studies. Over a dozen species have been spawned and cultured at the facility over the past 25 years. These have included Atlantic cod (Gadus morhua), haddock (Melanogrammus aeglefinus), silver-hake (Merluccius bilinearis), winter flounder (Pleuronectes americanus), summer flounder (Paralichthys dentatus), yellowtail flounder (Limanda ferrugineus), Atlantic mackerel (Scomber scombrus), scup (Stenotomus chrysops), sand lance (Ammodytes sp.), tautog (Tautoga onitis), striped bass (Morone saxatilis), and Atlantic herring (Clupea harengus). Recent work has concentrated on winter flounder, cod, and haddock. We currently maintain the only broodstocks of cod and haddock in the United States. Research underway with cod and haddock is designed to extend the portion of the year when first-feeding larvae are available, to describe the seasonal cycle of gamete production in haddock, and to assess the suitability of commercially-formulated diets for juveniles.

AN - 16125837; 4205485 AB - A clone of the diatom, Thalassiosira pseudonana, known as "3H", has been used widely in marine research and as an aquaculture feed for larval bivalve mollusks. The positive attributes of this strain include rapid division rates (ca. 1.5 per day), small size, and good nutritional biochemical composition. There is, however, one aspect of this diatom that makes it somewhat unreliable in culture - a reproductive stage in the life cycle that sometimes interferes with regular production schedules. As do all diatoms, 3H produces resting stages, called auxospores, as a consequence of the cell size reduction that accompanies cell division. In nature, these resting spores serve as seeds for regenerating populations following a period of poor environmental conditions. In this respect, delayed germination of auxosporesis is a survival strategy; however, when hatchery feeding schedules depend upon expected rates of vegetative growth, spore formation becomes a disadvantage in the hatchery. We maintained two identical carboy cultures of 3H with weekly semi-continuous harvest and replacement of 1/3 of the 18-liter volume for one year. We observed cycles in relative counts of auxospores and vegetative cells that appeared to be related to pH of the cultures. The pH decreases in cultures with more auxospores are consistent with decreased carbon uptake at a constant carbon-dioxide supply rate. We tested a strategy of decreasing carbon-dioxide supply rate when auxospore counts increased; this resulted in pH increases, which seemed to encourage auxospore germination. This finding suggests that an automated feedback loop in which decreased optical density (fewer vegetative cells), or a decrease in pH, actuates a decrease in carbon-dioxide supply rate and would improve the stability and dependability of continuous or semi-continuous cultures of 3H.

These beds were intentionally left untreated during cleanup activities, 1989-1991, because they provided physical stabilization and mussels were a food source for higher consumers. In 1992 and 1993, we documented 31 beds in Prince William Sound with sediment concentrations in excess of 10,000 mu g/g total petroleum hydrocarbons. Mussel concentrations of polynuclear aromatic hydrocarbons ranged to 10.0 mu g/g. Samples from these beds contained the highest oil concentrations seen since 1990, the year following the Exxon Valdez disaster. Beds were not recovering rapidly naturally and oil from these mussels could be incorporated into the food chain. Our purpose was to evaluate a simple, manual technique for removing oil that was in close contact with overlying mussels. In 1994, cooperatively with the Alaska Department of Environmental Conservation and residents from Chenega, twelve mussel beds were restored. Mussels were removed and allowed to wash one tidal cycle on absorbent pads. Oiled sediment underlying the mussels was removed, uncontaminated sediment substituted, and mussels replaced. Bed stability and hydrocarbon concentrations were measured periodically. Short-term evaluation of the process indicated successful removal of oil from close contact with overlying mussels. By August, 1995, sediments underlying the restored bed showed an average decrease in total petroleum hydrocarbons of 98%. Our results show that this simple method, although labor-intensive, is successful by providing a buffer of uncontaminated sediment underneath mussels, thereby reducing the body burden of petroleum hydrocarbons in these mussels.

The first year showed up to 7 times better survival of progeny of a brood stock selected on the basis of (1) survival and (2) presence of characteristic shell checks. The second year evaluated F sub(1) and F sub(2) progeny against progeny from susceptible brood stocks deployed in 7 different sites. Survival of F sub(1) and F sub(2) resistant seed was 7 to 25 times better than the susceptible seed. In 1996, we developed an F sub(3) generation and compared it with the F sub(2) progeny (FMF) from Flower Co. brood-stocks and a comparable aged susceptible control population from naive natural Connecticut brood-stocks (FCT). Surviving 1995 FCT progeny were used as brood-stocks to produce an F sub(1) resistant FCT strain. Seed were deployed in 5 different sites in Long Island waters: site 1 - Oyster Bay, Long Island Sound, FCT-F sub(1) (were not deployed here); site 2 - Mattatuck Inlet, Long Island Sound; site 3 - Cedar Beach, Peconic Bay; site 4 - a tidal pond, Peconic Bay; and site 5 - Moriches Bay, Great South Bay. Mortality results after 11 weeks of exposure were in: site 1 - (<20 mm) F sub(2) 20%, F sub(3)-16%, and FCT-79%, (unculled) F sub(2) 6%, F sub(3)-0, and FCT-55%; site 2 (unculled) F sub(2) 3%, F sub(3)-9%, FCT F sub(1)-2%, and FCT-70%; site 3 - (unculled) F sub(2) 15%, F sub(3)-26%, FCT F sub(1)-12%, and FCT-65%; site 4 (unculled) F sub(2) 55%, F sub(3)-29%, FCT F sub(1)-23%, and FCT-84%; site 5 (unculled, 9 weeks exposure) F sub(2) 12%, F sub(3)-0, FCT F sub(1)-5%, and FCT-0. Survival was 2.5 to 35 times better in the resistant populations. No significant differences were seen between any of the resistant populations. Management strategy using resistant seed has resulted in increased production to above pre-JOD levels and has eliminated the devastating effects of this disease.

Thirty-nine presentations covered topics that included new methods of micro-and macro-algal culture, bay and sea scallop farming projects, problems of exotic species introductions, juvenile and adult shellfish disease, methods to cope with low salinity when growing shellfish, results of some federally funded aquaculture training projects, and an extensive selection of papers devoted to state and federal policy issues relative to leasing of underwater lands for culture purposes and the permitting process necessary to obtain legal use for an aquabusiness. Representatives from forty-eight different aquaculture companies attended the seminar, a record number for this annual event. The participation of our speakers and exhibitors is greatly appreciated as is the financial support from our sponsors, the U.S. Department of Commerce's National Marine Fisheries Service, Woods Hole, MA and the U.S. Department of Agriculture's Northeastern Regional Aquaculture Center, N. Dartmouth, MA. The cooperation and interest of all who attended made this meeting a lively forum for the timely dissemination of new aquaculture information. Several commercial growers acknowledged that the Milford Aquaculture Seminar was the most important meeting for them to attend each year, the information gained from the meeting being directly beneficial to the "bottom line." In continuing a tradition of speakers and participants drawn from a diversified yet vitally interested group of persons involved in aquaculture ventures, the audience of 157 represented ten states, the District of Columbia, nineteen Universities, forty-eight aquaculture enterprises, nine consultants, and twenty-two marine labs as well as state or federal agencies tasked with aquaculture missions. Their interest and participation made our meeting a great success through the sharing of ideas and new technologies that aid and promote the growth of aquaculture.

These species seasonally occupy a coastal and offshore habitat that stretches from the Gulf of Mexico to the Gulf of Maine. They live in an often hazardous environment with a variety of human-induced impacts. Certain habitats, such as concentration areas, migratory routes, and areas for breeding, reproduction, and foraging are more critical to the survival of these species than others. Potential impacts from aquaculture operations range from direct injury and mortality from lines and cables to more subtle impacts on the food chain. The species, location and critical components of habitats and the potential impacts from culture operations will be identified. The development of aquaculture represents a change in marine resource harvesting methods from a system of hunting/gathering to farming/culturing. Historical methods of harvesting resources from the sea are not without conflicts with endangered and threatened species of marine life, and the new methods and requirements of farming in the oceans come with a whole new variety of gear types and methods. The ESA requires federal agencies to enter into consultation with NMFS on any activities in the marine environment that may interact with protected species and determine what reasonable and prudent measures or alternatives can be implemented to allow the activity to continue without undue harm to the species. In addition to giving an overview of the species, this discussion will review the requirements under the Act as it relates to the Aquaculture permit process. Understanding how to identify the potential impacts and the requirements of the law in the early planning stages of new aquaculture ventures will help reduce the burden of the ESA portion of the federal review process.

Can we? AN - 16124078; 4205544 AB - Most molluscan hatcheries feed larvae selected phytoplankton strains that are cultured on site. Following metamorphosis, post-set animals may be fed cultured algae for an additional period of days to several weeks. Thereafter, post-set are moved to land- or sea-based nursery systems in which the only food source is natural phytoplankton. Continuing to feed cultured algae to post-set bivalves is considered not to be economically viable, even though natural phytoplankton has several disadvantages (food quantity or quality may be poor and animals may be exposed to disease or predators at a susceptible size), and nutritionally-superior post-set algal diets have been found. Indeed, with algal-culture production costs on the order of $300-$500 per dry kilogram of algal biomass at most small- to medium-sized hatcheries, the economics of feeding cultured algae to post-set bivalves are not encouraging using current methods. Here we ask the questions: "Why is algal biomass so expensive to produce?" and "What can be done to bring the cost of algal culture down?" Biological limitations of most current algal-culture systems involve two processes: light utilization and gas exchange. Self-shading by dense cultures in most bottles and tanks (with three approximately equal dimensions) results in light-limited growth rates, often leading hatchery operators to increase artificial lighting at considerable expense. Gas-exchange problems can involve: 1) the inability of air-bubbling to provide enough carbon dioxide to keep pace with photosynthesis in open systems, leading to inhibitory pH increases, or 2) build-up of di-atomic oxygen in closed systems, such as tubular designs, leading to photosynthetic inhibition. Innovative designs of algal culture apparatus are needed that address these biological limitations. A first-order economic analysis of current algal-culture systems shows that greatest economic benefits will result from addressing four areas: 1) use of natural light, 2) high cell density to maximize light utilization and permit use of small culture vessels, 3) a continuous process to minimize labor, and 4) sterile operation to minimize "crashes" and increase shelf-life. Accordingly, development of a continuous, automated process designed around efficient utilization of natural sunlight, and incorporating effective gas exchange, offers the most attractive economic benefit for improving algal culture technology for nursery feeding of bivalves.

Dredging or filling proposals in shellfish habitat are subject to a rigorous regulatory review, but sometimes habitat losses are unavoidable. To prevent a net loss in shellfish habitat, adequate mechanisms must exist to offset further impacts by restoring or creating productive habitat. This presentation evaluates two attempts to mitigate for the loss of intertidal habitat (primarily for soft shell clams, Mya arenaria) through habitat restoration or creation. The first example, located in Searsport, Maine, involved the creation of new clam flats, and illustrates many of the mistakes that can lead to the failure of a mitigation project. The second example, located in Portsmouth, New Hampshire, involved the restoration of impounded intertidal habitat, augmented by the creation of new habitat. Although it is too soon to judge the success of this second example, the approach is far more holistic than the first example, and the initial monitoring results are promising. The presentation concludes with several recommendations for improving mitigation projects and advancing the state of knowledge for successful shellfish habitat restoration and creation. Shellfish mitigation projects can be enhanced by including scientifically sound techniques, quantifiable success criteria, benchmarks to control sites, thorough monitoring requirements, and realistic expectations. Most importantly, to avoid net losses of available habitat, further research is needed to develop reliable techniques for the restoration and creation of shellfish habitat.

Settlement densities of juveniles ranged as high as 7,000/m super(2). Causes of mortality varied among beds. Juveniles that settled on impenetrable hard clay substrates did not survive. Most settled in sand sediments, fewer in mud. Within weeks after settlement, many clams emerged from the bottom (cause not identified), laid on the surface, and died in 4-6 weeks. Observed predators of clams were fishes (mainly Fundulus sp.), black ducks (Anas rubripes), and horseshoe crabs (Limulus polyphemus). Man-related causes of mortality were: 1) smothering under mats of sea lettuce (Ulva lactuca) (possibly caused by eutrophication); 2) large waves dislodging the clams from sediments (this followed the loss of eelgrass in the 1940's; eutrophication has since prevented eelgrass growth; before then, the eelgrass had dampened the effects of waves on the clams); and 3) in July-August, 1995, most clams in the two rivers died when water temperatures persisted at about 30-31 degree C for several days (global warming?). In beds with no evident causes of mortality after the clams had attained a length of at least 15 mm, the survival rate was about 50% in 21 months, September 1993 to June 1995. The clams attained market size about 2 years after settlement. JF - Journal of Shellfish Research AU - MacKenzie, CL Jr AD - James J. Howard Lab., Northeast Fish. Sci.

Field studies conducted since 1992 investigating the prevalence and distribution of the parasite in blue crabs from coastal embayments along the Atlantic and Gulf of Mexico indicate that parasite prevalence follows a seasonal cycle. The parasite appears to be widely distributed with considerable variation in prevalence among sampled locations. Parasite prevalence and infection intensity are inversely related to crab size. Physical parameters of embayments such as salinity, temperature, depth, water mixing, tidal flow, and distance from inlets appear to influence prevalence of the parasite in blue crabs. Results from experiments assaying disease progression are paradoxical. Infection intensity increased in infected crabs held in flow-through coastal bay seawater, whereas infection intensity decreased in infected crabs held in static artificial seawater at a controlled temperature. Effects of this parasite on host mortality are unclear. With infections being heaviest and most prevalent in juvenile crabs, the parasite may be removing many blue crabs from coastal bay fisheries.

Bacterial and protistan agents have been investigated as causative agents of JOD, but the cause of the disease remains unknown. The disease was found to be readily transmissible in laboratory studies using infected oysters, or material filtered from the water column at one affected facility. Attempts were also made to transmit JOD to other cultured oysters, C. gigas and Ostrea edulis, and to uninfected C. virginica from clams reared in the same facility as JOD-infected oysters. Both C. gigas and O. edulis showed elevated mortalities, but histological examinations have not been completed for comparison to JOD. However, there has been no report of mortalities in O. edulis reared near JOD-infected C. virginica in the Northeast. No evidence of transmission was found from clams to oysters. Seventeen species of Vibrio and 32 species of other bacteria were isolated from oysters in our bacterial studies. Commonly recovered bacteria were isolated nearly as frequently from JOD-infected as uninfected oysters. Ciliates were routinely isolated from JOD-infected oysters, but rarely from uninfected oysters.

Overall, 1,184 lobster (7.9%) had lesions. Female lobster were more affected by this condition than male lobster. Shell-lesion occurrence was independent of carapace length. Disease prevalences in female lobster from canyons within the "potential area of influence" of the 106-Mile Site were significantly higher than those from canyons located outside of this area. However, logistic regression tests showed an equally strong regression of shell lesion occurrence with proximity to the old 12-Mile Dumpsite as that shown by proximity to the 106-Mile Dumpsite. Shell disease prevalences in a smaller sample of lobster examined during groundfish survey cruises were not significantly different from those in commercial catches. A cause and effect relationship between sewage-sludge dumping at the deep-water dumpsite and shell-disease occurrence could not be proven because of the possible existence of a 12-Mile Site effect and other factors. The possibility of multiple influences from both the 106-Mile Site and the 12-Mile Site on offshore shell-disease prevalence could not be discounted. Further analysis based upon a lesion severity index (currently in progress) may help to clarify possible dumpsite effects.

AN - 1438551516; 9800053 AB - Analyzes the uses & limitations of the think-aloud technique of cognitive interviewing for questionnaire pretesting & development. The think-aloud technique requires subjects to provide verbal reports of their thought processes while trying to answer study questions. It is argued here that some of the subjects' thought processes may be hard to verbalize or unconscious -- a situation that challenges the efficacy of using the think-aloud technique. Nevertheless, cognitive interviewing techniques have evolved with time & are used primarily to ask probe questions about the meaning of words, thus eliciting linguistic, ethnographic, & contextual information that should be fairly accurate. It is concluded that more types of questionnaire research should be developed to supplement the cognitive interview as an information-gathering mechanism. 48 References.

AN - 36405894; 6431 AB - PURPOSE: The implementation of a management plan for the Thunder Bay National Marine Sanctuary, an 808-square-mile area on Lake Huron in Michigan, is proposed. The region contains about 160 shipwrecks that span more than a century of Great Lakes maritime history. In 1981, Michigan designated the area a bottomland preserve in order to protect these underwater cultural resources. If designated a national marine sanctuary, the area would be under the joint management of the state of Michigan and the National Oceanic and Atmospheric Administration (NOAA). Under the proposed action, the NOAA would adopt regulations for cultural resource protection not covered by existing state regulations. The proposed boundary of the sanctuary would extend from Presque Isle Lighthouse, south to Sturgeon Point Lighthouse, and lakeward to longitude 83 degrees west. Both lighthouses have visitor centers and museums, which would allow for easy access by sanctuary visitors. Two additional boundary alternatives and a No Action Alternative are considered in this draft EIS. Under the Existing Preserve Alternative, the NOAA would adopt the existing state-designated preserve, which is 290 square miles. Under the Alpena County Latitudes Alternative, the NOAA would use the northern and southern latitudes of Alpena County and extend the boundary lakeward to longitude 83 degrees west. This boundary alternative would be 448 square miles. POSITIVE IMPACTS: The preservation of Thunder Bay as a national marine sanctuary would provide for a long-term integrated program of resource protection, research, and interpretation/education to assure comprehensive management and protection of this natural resource.

AN - 36400011; 6423 AB - PURPOSE: The amending of the management plan for the shrimp fishery in the Gulf of Mexico fishery conservation zone is proposed. The current management plan covers brown shrimp, white shrimp, pink shrimp, royal red shrimp, seabobs, and rock shrimp in the gulf as well as territorial seas and associated bays, inlets, wetlands, and upland areas in Alabama, Florida, Louisiana, Mississippi, and Texas. The amendment would establish new guidelines and procedures designed to reduce the unwanted bycatch of juvenile red snapper by shrimp trawls operating in the gulf. Red snapper and other nontarget finfish incidentally taken in shrimp trawls are generally discarded dead. The red snapper stock in the gulf of Mexico is considered to be overfished, and even if the directed fisheries for red snapper were closed to all harvesting, the stock would not recover from overfishing because of the excessive loss from bycatch of juveniles in shrimp trawls. In 1993, 34 million juvenile red snapper were estimated to have been discarded as shrimp bycatch. The amendment would require the installation of bycatch reduction devices in each net used aboard vessels trawling for shrimp in specified areas of the gulf. Butterfish and groundfish trawlers and vessels trawling for royal red shrimp would be exempt from this requirement. The requirement would be geographically limited to the northern and western gulf within the 100-fathom contour west of Cape San Blas, Florida. The goal of the amendment is to achieve a 50 percent reduction in juvenile red snapper mortality in the gulf. POSITIVE IMPACTS: The amendment would help the red snapper population to become reestablished in the gulf. Restricting the geographic scope of the requirement to areas where red snapper dominate (the northern and western gulf) would help to reduce the adverse economic effects on commercial shrimp operations. NEGATIVE IMPACTS: Because bycatch reduction devices would not be completely effective, some incidental take of red snapper would continue to occur. In addition, the use of the devices would result in a decline in shrimp biomass ranging from 5.9 to 8.2 percent.

Preparation date: May 28, 1997 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - CONSTRUCTION OF THE PALAU COMPACT ROAD, BABELDAOB ISLAND, REPUBLIC OF PALAU. AN - 16350712; 6394 AB - PURPOSE: The construction of a two-lane road system on the island of Babeldaob in the Republic of Palau is proposed. The 127-square-mile island of Babeldaob is the largest island in the Palau archipelago and the second largest island in Micronesia. The island extends in a north-south direction for approximately 28 miles. The southern two-thirds of the island has an average width of eight miles, while the northern third consists of a narrow spur with an average width of one mile. The interior portion of the island is largely uninhabited partly because of limited access via land transportation systems. Existing roads connecting settlements on the island consist of dirt, gravel, or crushed coral surfaces. Three alternatives are considered in this draft EIS; the No Action Alternative was eliminated because it would fail to address existing practices and conditions which have a damaging effect on the environment. Under the preferred alternative, a loop system would be constructed in the southern two-thirds of the island and a single spur on the more narrow northern portion. The 53 miles of roadways would connect all ten states on the island and bypass existing settlements instead of running through them. Therefore, the roadway system would need to be complemented by secondary roads connecting to existing settlements. The construction of the roadway would be jointly funded by the U.S. government and the government of Palau. POSITIVE IMPACTS: Under the preferred alternative, the project would provide island-wide access to all settlements while minimizing disturbance to existing communities. The road would also provide access to areas with potential for agriculture, forestry, mining, industry, and tourism, and near watersheds for future water resource development, rock sources for quarries, and port development sites. The road would provide residents of the island an opportunity to live on their land and commute to work in Koror, rather than having to rent additional living quarters at or near Koror, as is now the practice. The project would generate 1,600 jobs per year in construction-related work and 3,088 indirect jobs. NEGATIVE IMPACTS: The economic development expected to result from roadway construction would gradually erode a traditional way of life. Land-disturbing activities could adversely affect geology and topography, soils, water quality, air quality, noise levels, flora, fauna, and coastal, marine, and estuarine resources.

AN - 79096828; 9203287 AB - More than 20 countries have either established or proposed regulatory limits for one or more of the paralytic shellfish poisoning (PSP) toxins as they occur in seafood products. PSP toxin levels are generally estimated using the standard AOAC mouse bioassay, yet because of various limitations of this method [e.g. high variability (+/-20%), low sensitivity, limited sample throughput and use of live animals], there remains a need for alternative testing protocols. A sensitive and selective, high capacity assay was developed for the PSP toxins which exploits the highly specific interaction of these toxins with their biological receptor (i.e. voltage-dependent sodium channel) and is thus based on functional activity. This receptor binding assay provides a radioactive endpoint, and is performed in a microtiter filter plate format with results determined by standard liquid scintillation counting within 24 hr. The Ki for the assay is 3.66 +/- 0.86 nM saxitoxin, with a limit of detection of c. 5 ng saxitoxin/ml in a sample extract. Good quantitative agreement of the assay with both mouse bioassay and high-performance liquid chromatographic analysis of crude extracts of contaminated shellfish, as well as PSP toxin-producing algae, was observed. Our findings indicate that the receptor binding assay has a strong predictive value for toxicity determined by mouse bioassay, and that this approach warrants consideration as a rapid, reliable and cost-effective alternative to live animal testing for detection and estimation of PSP-related toxicity in seafood and toxic algae.

These studies have contributed to identifying the origin and evolution of petroleum and natural gases using stable C and H isotopes. The results of pyrolysis experiments at 400-600 degrees C on model compounds are presented, to examine differences in isotope fractionation due to maturity, T of formation and the strength of the thermal C-C bonds in the parent organic material. At higher T methane decomposes to amorphous C and hydrogen. At > or = 700 degrees C the C in methane undergoes isotope exchange with amorphous C. The first methane formed is quite heavy and formed apparently by the carbonium ion mechanism rather than by the free radical mechanism. Exhaustive pyrolysis, until no additional methane is formed, is used in the pyrolysis-C isotope method for determining the maturity of kerogen.

The long-wavelength radial orbit error is suppressed below the noise level of the altimeter by taking the along-track derivative of each profile. Ascending and descending slope profiles are then interpolated onto separate uniform grids. These four grids are combined to form comparable grids of east and north vertical deflection using an iteration scheme that interpolates data gaps with minimum curvature. The vertical gravity gradient is calculated directly from the derivatives of the vertical deflection grids, while Fourier analysis is required to construct gravity anomalies from the two vertical deflection grids. These techniques are applied to a combination of high-density data from the dense mapping phases of Geosat and ERS 1 along with lower-density but higher-accuracy profiles from their repeat orbit phases. A comparison with shipboard gravity data shows the accuracy of the satellite-derived gravity anomaly is about 4-7 mGal for random ship tracks. The accuracy improves to 3 mGal when the ship track follows a Geosat Exact Repeat Mission track line. These data provide the first view of the ocean floor structures in many remote areas of the Earth. Some applications include inertial navigation, prediction of seafloor depth, planning shipboard surveys, plate tectonics, isostasy of volcanoes and spreading ridges, and petroleum exploration.

The measurements provide a high-resolution depiction of the vertical structure of reflectivity and vertical velocity within the gust front, the outflow, and the parent storm. Earlier gust front remote sensing studies have used Doppler observations obtained with low-elevation-angle scans to accurately measure the horizontal flow pattern from which vertical velocities were subsequently estimated by integrating the continuity equation. In contrast, the New Salem case provides direct, rather than derived, Doppler measurement of vertical velocities with better vertical resolution and vastly superior temporal resolution. The gust front's vertical structure is in general agreement with earlier observations and numerical simulations, except that the transition from strong upward to strong downward motion was more abrupt. The maximum updraft, of almost 10 m s super(-1[/supscript], was measured in the gust front at 1.35 km above ground level and was followed by equally strong downward motion only 1 min later at a slightly higher altitude.The observations support the earlier use of the continuity method for deriving the basic pattern of vertical motions in density currents from quasi-horizontal scan data.)

Although comparison of individual months can suggest a decrease in greenhouse trapping from cold to warm conditions, when the entire 4-yr record is considered a distinct increase in tropical-mean greenhouse trapping of similar to 2 W m super(2) is observed in conjunction with a similar to 0.4 K increase in tropical-mean sea surface temperature. This observed increase compares favorably with GCM simulations of the change in the clear-sky greenhouse effect during El Nino-Southern Oscillation (ENSO). Superimposed on top of the SST-driven change in greenhouse trapping are dynamically induced changes in tropical moisture apparently associated with a redistribution of SST during ENSO. The GCM simulations also successfully reproduce this feature, providing reassurance in the ability of GCMs to predict both dynamically and thermodynamically driven changes in greenhouse trapping.

Results showed indications of well-defined plumes from North America and Europe from both chemistry and back trajectory data. Elevated ozone concentrations were also observed in airmasses from uninhabited continental regions. Chemical and meteorological data were incorporated into a simple photochemical model in which ozone destruction predominated over generation.

Part of our evaluation of this hypothesis involved the use of conventional radio and satellite-linked time-depth recorder transmitters to compare summer and winter foraging of adult female and young-of-the-year Steller sea lions in Alaska waters. Foraging effort was not significantly different seasonally for postpartum adult females, though females with dependent young in winter may increase their foraging effort. In winter, all adult females made longer trips over larger home ranges and dove deeper. Young sea lions exerted less foraging effort, had the shallowest and briefest dives, and had home ranges intermediate in size to the two groups of adult females. Their foraging ability appears to develop throughout the first year. We conclude that adult female sea lions can exploit prey throughout the Gulf of Alaska and Bering Sea, and are constrained only by their reproductive status and seasonal changes in prey availability. Young sea lions' diving is more limited because their physiological and behavioral development constrains them from diving like an adult. Perhaps most important, dives remain shallow through the first year. Consequently, young sea lions could be more easily food-limited by changes in prey distribution.

By October 11, 1998 each fishery management plan must identify and describe essential fish habitat (EFH) for managed species, minimize adverse effects on EFH caused by fishing, and identify other actions to encourage the conservation and enhancement of EFH. In New England, the fishery management plans for groundfish, scallops, and Atlantic salmon must be amended to address the EFH requirements, and the new fishery management plan for Atlantic herring will have to include EFH provisions as well. The Magnuson-Stevens Act also requires each federal agency to consult with NMFS regarding any activity authorized, funded, or undertaken by the federal agency that may adversely affect EFH. NMFS is required to provide conservation recommendations on federal and state agency activities that would harm EFH. Although NMFS' recommendations are not mandatory conditions, for each action the federal agency must respond in writing to describe the measures the agency will take to protect EFH, and to explain its reasons for not accepting any of the recommendations. The requirement for fishery management plans to "minimize to the extent practicable adverse effects on EFH caused by fishing" will be implemented in New England through the Fishery Management Council. In determining what types of management measures are "practicable" the Council will consider issues such as the nature and extent of any adverse effect on EFH, and whether the benefit to EFH achieved by minimizing the adverse effect justifies the cost to the fishery. Any specific management approaches to mitigating gear impacts will be developed through the Council process, which provides opportunities for public involvement to address concerns between gear sectors and other issues. The overall goal of the EFH provisions of the Magnuson-Stevens Act is to facilitate more of an ecosystem-based approach to fishery management, whereby habitat protection and harvest management are coordinated better to enhance the sustainability of marine fisheries.

This paper aims at detecting temporal trends at large spatial scales using contaminant data from 1986 to 1994 of the U.S. National Status and Trends Mussel Watch Program. U.S. coasts are divided into 10 large areas. After a logarithmic transformation of the data, linear models are used and include a 'sampling site' effect, a linear trend estimated for each area, weather covariates, and an 'analysis' effect reflecting changes of analytical procedures or even laboratories. Except for the Californian coast, chlorinated organic compounds show rather uniform decreases, which can be attributed to bans put on these contaminants. A few increasing trends were detected for trace elements, which also showed few decreases. Additions of weather covariates and possible analysis effects were intended to model apparently random between-year variations in contaminant time-series. Although low in terms of percentage of variability explained, the addition of these effects might have avoided the detection of spurious trends for some contaminants.

Eight round-trip flights were made over this 1000 kilometer path, with each flight incorporating several profiling descents from approximately 4.2 km altitude to the surface. On a 10-second time base were recorded measurements of aerosol black carbon (BC), condensation nuclei (CN), air temperature and absolute barometric pressure, from which altitude was deduced. Some profiles showed considerable vertical structure with numerous temperature inversions and stratified aerosol layers. Peak BC and CN concentrations exceeded 1000 ng m super(-3) and 1000 cm super(-3) respectively. Occasionally, extremely clean air was found in some layers. Other descents showed stable temperature profiles, with aerosol BC and CN distributed throughout the lower 4 km of the atmosphere. In most cases, the surface temperature-inversion layer contained high concentrations of aerosol species. We conclude that the atmosphere in this remote area is strongly affected by anthropogenic emissions from distant source regions, and that the meteorological and aerosol concentration profile structures were similar to those regularly observed in the western sectors of the Arctic in springtime.

Numerical integrations of this model in geostrophic coordinates are performed in the context of a typical midlatitude squall line characterized by a leading convective line and a trailing stratiform rain region. Some dynamical insights are provided by these integrations in conjunction with the theoretical framework, which seem to be unavailable by primitive-equation model simulations. A more complete dynamical picture of a squall line circulation system is revealed from this study: a balanced midlevel horizontal vortex coupled with an ageostrophic transverse circulation in the normal-line plane. This configuration suggests an interaction between two distinct dynamical scales, that is, the scales with geostrophic and ageostrophic-like motions, both of which play important roles in mesoscale convective systems. The internal and external physical processes that affect the ageostrophic transverse circulation are further discussed.

AN - 36409584; 6363 AB - PURPOSE: The restoration of natural resources damaged by long-term industrial pollution in New Bedford Harbor, located in southeastern Massachusetts, is proposed. The project area includes the Acushnet River watershed, south through the Acushnet River Estuary and New Bedford Inner and Outer Harbors, out to the Area III fishing closure line, and adjacent shoreline areas. New Bedford Harbor is a small, urbanized estuary and important commercial port on western Buzzards Bay. From the late 1940's until 1977, manufacturers in New Bedford discharged industrial wastes containing polychlorinated biphenyls (PCBs) and toxic metals in the harbor and nearby coastal environments, resulting in widespread, severe contamination of the sediments, water column, and biota of the harbor estuary and parts of Buzzards Bay. Dredging of these contaminated sediments is presently underway and is expected to last ten years. Without the proposed restoration effort, the recovery of the harbor ecosystem would take decades or longer. The plan developed by the New Bedford Harbor Trustee Council contains 12 preferred alternatives for restoring marshes and wetlands, recreational areas, and wildlife. The plan would be financed through a $21.0 million fund established as a result of settlements between the federal government, the Commonwealth of Massachusetts, and the companies responsible for polluting the harbor. Major restoration projects would include hydrologic restoration of Padanaram Salt Marsh and Nonquitt Marsh; altering a culvert in the harbor to improve tidal exchange; recreational and habitat improvements to Fort Taber Park and Riverside/Belleville Avenue Marine Recreational Park; eelgrass habitat restoration at New Bedford Harbor and Clarks Cove; and the restoration of shellfish, the Acushnet River herring run, and Buzzards Bay tern. POSITIVE IMPACTS: By beginning restoration activities while cleanup is still underway, the proposed plan would accelerate the return of the harbor ecosystem to its pre-pollution condition.

AN - 78962547; 9133702 AB - The National Institute of Standards and Technology, NIST (formerly National Bureau of Standards), is the nation's standards laboratory for civilian technology. NIST develops and maintains the nation's physical measurement standards for medical therapy and diagnostics. For the past 50 years, NIST has developed radioactivity Standard Reference Materials (SRMs) for radioiodines as well as decay-scheme data and test methods for use by the radiopharmaceutical manufacturers in their quality assurance and quality control at the point of manufacture. Methods of standardizing radioiodines include 4 pi beta-gamma coincidence counting (131I), 4 pi beta-gamma anti-coincidence counting (129I), 4 pi(e,x)-gamma coincidence counting (123I), and x-gamma sum peak coincidence counting (125I). NIST also uses sources standardized by these techniques to calibrate re-entrant ionization chambers (dose calibrators) and scintillation counters. SRMs of 131I and 125I are now available on an annual basis, and the long-lived 129I has recently been reissued.

Current Population Reports. AN - 62512461; ED411291 AB - This update to the School Enrollment Report of the Current Population Survey presents detailed tables about the school enrollment of the civilian, noninstitutionalized population of the United States. It is the first update of a new series designed to reduce the number of printed reports by updating Current Population Survey tables annually while issuing the full report only every other year. The tables in this compilation provide information on the 70 million people enrolled in nursery school through college. About 8.3 million children were enrolled in nursery school or kindergarten during the period, while elementary school enrollment stood at 31.8 million students. High school enrollment totaled 15.0 million people, and the annual high school dropout rate was 5.4%. The number of people enrolled in college was 14.7 million, and about 6.0 million college students were 25 years of age or older. Data are estimates based on a sample survey and are subject to sampling variability since they are not based on a complete enumeration of the population. Appendixes present historical enrollment tables, definitions and explanations, and a discussion of the source and accuracy of the estimates. (Contains 19 detailed tables.)

This gravity field reveals regional tectonic fabric, such as gravity lineations, which are the expression of fracture zones left by early (65 to 83 mya) Pacific-Antarctic sea-floor spreading that separated the Campbell Plateau and New Zealand continent from West Antarctica. These lineations constrain plate motion history and confirm the hypothesis that Antarctica behaved as two distinct plates, separated from each other by an extensional Bellingshausen plate boundary active in the Amundsen Sea before about 61 mya.

In other regions, planetary vortices exist selectively for a limited range of generic (exponential) vertical forms and can be used to probe the atmospheric structure theoretically. A study of vortex genesis with a three-dimensional numerical model produces reasonably realistic simulations of the Great Red Spot for both the generic and galilean forms, provided that Jupiter's winds do not extend much beyond a 500 km depth. However, the actual depth of the winds remains uncertain.

In the first numerical experiment in which freshwater is discharged into high North Atlantic latitudes over a period of 500 years, the thermohaline circulation (THC) in the Atlantic Ocean weakens, reducing surface air temperature over the northern North Atlantic Ocean and Greenland and, to a lesser degree, over the Arctic Ocean, the Scandinavian peninsula, and the Circumpolar Ocean and the Antarctic continent of the southern hemisphere. Upon the termination of the water discharge at the 500th year, the THC begins to intensify, regaining its original intensity in a few hundred years. With the exception of the Pacific sector of the Circumpolar Ocean of the southern hemisphere, where the surface air temperature recovery is delayed, the climate of the northern North Atlantic and surrounding regions rapidly resumes its original distribution. The evolution of the ocean-atmosphere system described above resembles the Younger Dryas event as inferred from the comprehensive analysis of ice cores and deep-sea and lake sediments. In the second experiment, in which the same amount of freshwater is discharged into the subtropical North Atlantic again over a period of 500 years, the THC and climate evolve in a manner qualitatively similar to the first experiment. However, the magnitude of the THC response is 4-5 times smaller. It appears that freshwater is much less effective in weakening the THC if it were discharged outside high North Atlantic latitudes.

This is done by comparing the temperature variations following the three eruptions with the average quasi-biennial variation in temperature obtained by applying the superposed epoch method to the 13 QBO cycles (centered on Singapore 50 mbar east wind maxima) between 1958 and 1996 which do not include these three eruptions. Confidence estimates are based on the 2-standard deviation value of the 13 comparisons. Shown are estimates of the volcanic impact and approximate 95% confidence intervals in 300-100 and 100-50 mbar layers of polar, temperate, subtropical, and equatorial zones (and the globe as a whole), as well as in north subtropical and equatorial zones at pressure surfaces of 50, 30, 20, and 10 mbar. Based on this procedure, and ignoring other possible influences on stratospheric temperature, all three eruptions warmed the tropical low stratosphere by nearly 2 degrees C, with the largest warming 3 degrees C at 50 mbar in the equatorial zone following Agung and Pinatubo. Above 50 mbar, the volcanic warming usually decreases with height in the tropics, an exception being the 2 degrees C warming of the 10 mbar surface in the north subtropics following El Chichon. While the volcanic warming is most frequently a maximum 2 seasons after the eruption, the warming duration can be 2 years.

AN - 36402231; 6349 AB - PURPOSE: The establishment of a coastal management program for the shoreline and waters of Lake Erie under the jurisdiction of the state of Ohio is proposed. Ohio is responsible for managing 262 miles of mainland and island shores as well as 3,277 square miles of Lake Erie waters. The jurisdictional area includes all of the waters of Lake Erie to the international boundary with Canada, the islands in the lake, the bed of the lake, and adjacent shorelands within Ohio. Approximately 33,000 acres of coastal wetlands support at least 250 species of nesting birds. Shallow waters in the island and bay region provide fish spawning grounds and nurseries, sustaining a commercial and sport fishing industry that provides numerous benefits to citizens of Ohio. The program would affect those uses with direct and significant impact on coastal waters, including lands subject to lake flooding and erosion, estuaries and wetlands, coastal recreation areas, and areas of lake-related uses. The program would include a comprehensive coastal erosion and floodplain management plan that would delineate 30-year coastal erosion areas; enforce rules on new structures in erosion areas; regulate design and construction of dams, dikes, and levees; and enforce local government compliance with state and federal policies. The program would also include separate plans for managing water quality, wetlands and other sensitive areas, ports and shoreline development, fish and wildlife, oil and gas and minerals development, and waste management. Critical fish habitat, ports and harbors, state nature preserves and wildlife areas, erosion and flood hazard areas, public parks and access areas, and wetlands would be designated areas of critical concern. POSITIVE IMPACTS: The implementation of the state program would make the state eligible for federal funds to enhance coastal management along Lake Erie. These funds could be used for erosion and flood hazard area management, the enhanced protection of wetlands and other coastal natural areas, the improvement of coastal air and water quality, and the expansion of recreational access. NEGATIVE IMPACTS: Persons owning shorefront property in areas with erosion rates could experience a decrease in property values as a result of the installation of erosion control structures.

Species identifications were made from fish otoliths and cephalopod beaks recovered from 428 stomachs collected throughout the eastern tropical Pacific between 1989 and 1991. The most frequently found fish were lanternfish (family Myctophidae) at 40%, and the most frequently found cephalopods were flying squids (family Ommastrephidae) at 65%. The dominance of these primarily mesopelagic prey species and a significantly higher stomach fullness index for stomachs collected during the morning hours ( chi super(2)=112.99, df=6, P<0.0001) suggest that pantropical spotted dolphins feed at night when many mesopelagic species migrate toward the surface. Significant differences in prey composition by season and geographic region indicate that pantropical spotted dolphins are flexible in their diet and may be opportunistic feeders. Comparison of the diets of pregnant and lactating female dolphins revealed that lactating females increase both the proportion of squid in their diet and quantity of food consumed.

The data indicate that C. pauciradiatus is a species whose adult spawning grounds and larval habitat are tied to sharp temperature gradients. These gradients occur along the edge of the Loop Current in the eastern Gulf of Mexico and along the anticyclonic-cyclonic rings in the western Gulf of Mexico. Transects made across the Loop Current, in 1987 and 1988, show that larval C. pauciradiatus is found close to the frontal interface and that peak abundance occurs before peak SST (sea surface temperature). Variation in the extent of the frontal systems in the Gulf of Mexico would be expected to affect annual recruitment of a species that is tied to a frontal habitat. Annual abundance of C. pauciradiatus varied considerably but was similar to that of other pelagic species. This finding suggests that the physical processes in the Gulf of Mexico may affect a wide range of species.

Duwamish Waterway sediment has high concentrations of both polychlorinated biphenyls (PCB's) and polycyclic aromatic hydrocarbons (PAH's), Eagle Harbor sediment has high concentrations of PAH's, and Sinclair Inlet sediment has low concentrations of PAH's and moderate concentrations of PCB's, whereas sediments at Port Susan, the reference site, are minimally contaminated. Fish from the Duwamish Waterway and Eagle Harbor had significantly higher levels of fluorescent aromatic compounds (FAC's) in bile than sole from Port Susan and Sinclair Inlet, and fish from the Duwamish Waterway had significantly higher concentrations of PCB's in ovary and liver tissue than fish from the other sampling sites. Fecundity and egg weight were compared in fish of equivalent size, age, and reproductive maturity from the four sites; fish from the Duwamish Waterway showed significantly higher relative fecundity and lower egg weight than fish collected from the three other sites. Production of more and smaller eggs in fish from the Duwamish Waterway site was associated with elevated hepatosomatic indices, elevated plasma triglyceride levels, and elevated levels of PCB's in liver and ovarian tissue, and reduced plasma vitellogenin levels (as estimated from alkali-labile protein (ALP) concentrations). Fish from the Duwamish Waterway and Sinclair Inlet also had higher age-specific fecundity than animals from other sites because of their larger size at age. On an individual fish basis, elevated tissue PCB concentrations were significantly correlated with low plasma ALP, reduced egg weight, and increased egg number, whereas elevated biliary FAC's were associated with increased ovarian atresia, increased egg weight, and reduced egg number. The results of this study suggest that English sole exposed to chemical contaminants may experience alterations in egg development; however, nutritional or other environmental factors may also contribute to the observed intersite differences in egg weight and fecundity.

Tags recovered from these fish have provided one of the best sets of data available for estimating tag-shedding rates. We developed a new model and a maximum-likelihood procedure to estimate the rates. Both initial and long-term shedding rates were low, but posteriorly placed tags were shed at about twice the rate of anteriorly placed tags. Bootstrapping indicated that the estimates were precise and accurate. Shedding rates for sablefish were considerably lower than most published estimates for other species. Although the rates were low, the extra tag increased recoveries by nine percent over a six-year period.

The two spaces can be either two inside rooms of a multi-room facility or one inside room and the outside ambient environment local to the vent. The flow is determined by consideration of standard orifice-type flows, driven by cross-vent pressure differences and, when appropriate, the combined pressure- and buoyancy-driven flows which occur when the density configuration across the vent is unstable, i.e. a relatively cool, dense gas in the upper space overlays a less dense gas in the lower space. The algorithm calculates rates of flow exchange between the two spaces based on previously reported model equations. VENTCF2 is an advanced version of the algorithm/subroutine VENTCF in that it includes an improved theoretical and experimental basis. The subroutine is completely modular and it is suitable for general use in two-layer, multi-room, zone-type fire model computer codes. It has been tested numerically over a wide range of input variables and the results of some of these tests are described. JF - FIRE SAF. J.

Unfortunately, coincident in situ samples for identifying their cause are lacking. To ascertain the likelihood that these patches represent surface blooms of the coccolithophore Emiliania huxleyi, their distribution pattern was mapped and their spectral signature evaluated by classifying CZCS imagery with a supervised, multispectral classification scheme that had been developed to detect this phytoplankton species. On the basis of the similarity of these characteristics to those of documented cases, we conclude that the high-reflectance patches observed in surface waters of the shelf and beyond are E. huxleyi blooms. The blooms seasonally occupied an area as large as 550,000 km super(2). Standing stock estimates indicate that the detected blooms produced an average of 1.5-4.9 x 10 super(5) metric tons of calcite carbon and 4.0 x 10 super(3) t of dimethyl sulfide sulfur.

AN - 16109931; 4208011 AB - Benthic faunal abundances and biomasses in adjacent mangrove, seagrass and non-vegetated mud habitats were compared in Rookery Bay, Florida, U.S.A. Although all habitats were intertidal, mangroves received the shortest duration of flooding, and non-vegetated mud received the longest. Replicate cores were taken at high tide in each habitat in July, September and December 1988, and in April 1989. Seagrass substrates were low organic content sands, whereas mangrove and non-vegetated substrates were high organic content sandy clays. Over 300 taxa were recorded, most of them relatively rare, and only 32 taxa were considered dominant (averaging greater than or equal to 636 individuals m super(-2) or five core super(-1) in any habitat at a given time). Seagrass and non-vegetated mud faunas were more diverse than those of mangrove substrates. Total densities were always higher in red mangrove (Rhizophora mangle) peat than elsewhere, averaging 22 591 to 52 914 individuals m super(-2). Densities in mixed seagrasses ranged between 6347 and 23 545 individuals m super(-2), while those in non-vegetated mud ranged between 3611 and 22 465 individuals m super(-2). Biomasses, however, were always higher in either seagrasses (15 super(.)7-87 super(.)4 g wet weight m super(-2)) or non-vegetated mud (11 super(.)9-26 super(.)2 g m super(-2)) than in mangroves (3 super(.)6-8.2 g m super(-2)). Tanaids and annelids were the numerical dominants, reaching maximum densities of 35 127 and 31 388 m super(-2), respectively, in mangroves. Annelids were also the dominant biomass in most habitats each month. Variation in densities of most of the 32 dominant taxa were related to habitat not time. Each habitat harboured four to eight taxa that were significantly more abundant there than in alternate habitats. Feeding guild analysis indicated few differences among habitats, as surface deposit feeders and carnivores were predominant. Red mangrove appear capable of functioning in a manner similar to intertidal marsh habitats by providing high densities of small prey items for mobile consumers able to exploit the intertidal zone during high tide. Experimental verification of this function remains necessary. JF - Estuarine, Coastal and Shelf Science AU - Sheridan, P AD - U.S. Dep. Commerce, NOAA, Natl. Mar. Fish. Serv., Southeast Fish. Sci.

These data indicate that there have been no systematic winter temperature trends at altitudes of 7-25 km and thus no expected changes in stratospheric cloud particle surface area, which would affect heterogeneous chemistry. Springtime ozone depletion has been very severe since about 1992, with near-total loss of ozone in the 14- to 18-km region, but has lessened somewhat in 1994 and 1995. Sulfate aerosol particles from the Pinatubo eruption resulted in new ozone depletion in 1992 and 1993 in the 10- to 12-km region where it is too warm for polar stratospheric clouds (PSCs) to form. Although ozone depletion was not as severe in 1995 as in 1993, the depleted region remained intact longer than ever, with record low values throughout December in 1995. Since about 1992, a pseudo-equilibrium seems to have been reached in which springtime ozone depletion, as measured by the total column or the ozone in the 12- to 20-km main stratospheric cloud region, has remained relatively constant. Independent of volcanic aerosol, ozone depletion has extended into the upper altitudes at 22-24 km since about 1992. There is some indication that ozone depletion has also worsened at the bottom of the depletion region at 12-14 km. Extensions of the ozone hole in the vertical dimension are believed to be the result of increases in man-made halogens and not due to changes in particle surface area or dynamics. It is estimated that if the Montreal protocol and its amendments, banning and/or limiting substances that deplete the ozone layer, is adhered to, recovery of the Antarctic ozone hole may be conclusively detected from the aforementioned changes in the vertical profile of ozone as early as the year 2008. Future volcanic eruptions would affect ozone at 10-16 km, making detection more difficult, but indicators such as depletion in the 22- to 24-km region will be immune to these effects.

The trajectories were then paired with surface ozone data to determine the dependence of surface ozone on transport. The two main transport regimes affecting surface ozone are trade wind transport, where trajectories show flow bringing ozone from the east in the tropical marine boundary layer, and midlatitude transport, where trajectories show strong westerly flow at higher elevations of southern midlatitudes, followed by descent with anticyclonic curvature. These two transport regimes yield ozone from distinctly different origins, having different mixing ratios. The seasonally changing frequency of transport type is shown to be partly responsible for the seasonal cycle and changes in variability of Samoa surface ozone. On average, 45% of winter ozone variation can be explained by differences in transport type. This strong relationship was absent, however, during 1991, probably because of UV blocking by aerosols from the eruption of Mount Pinatubo. Reduced total column ozone during winter 1992 may have contributed to this season having the lowest surface ozone levels of the study period. JF - Journal of Geophysical Research. D.

Ice crystals of the varied growth habits depolarize and backscatter millimeter-wavelength radiation according to crystal aspect ratio, bulk density, and orientation, and the polarization state of the incident radiation. In this paper model calculations of the depolarization caused by various crystal types are extended from previous work, and K sub(a)-band (8.66 mm) radar measurements of linear and elliptical depolarization ratios (LDR and EDR) from various ice hydrometeors are presented. The measurements for regular crystals are related to the models. Drizzle drops, which are quasi-spherical, serve as a reference. Signature discrimination in cloud systems with more than one type of hydrometeor is addressed. The model calculations illustrate the interplay of the parameters that control depolarization. They predict that in the depolarization signatures, crystals of the various basic planar and columnar habits should generally be most separable, one habit group from another and, to a degree, within each group when they occur in common, mature size distributions. It is verified in this and related papers that measurements of depolarization with a K sub(a)-band dual-polarization radar provide good estimates of hydrometeor identity to separately distinguish drizzle, pristine crystals of various growth habits, graupel, and aggregates in winter storm clouds that have reasonable horizontal homogeneity over short distances ( similar to 10-20 km). Characterization of the mix of two or three hydrometeor types is also possible, once the individual types are identified in some part of the cloud. Quantitative agreement between the measurements and the models, supported by snow crystal samples, was much better for EDR than for LDR; that is, EDR enabled more specific hydrometeor identification. However, LDR provided indications of randomness of crystal orientation and a wider decibel gap differentiating graupel from drizzle.

The toxic response and BCFs were vastly different among the species when exposed to the dissolved compound, which was reflected in their unequal uptake clearance and elimination rate constants. Based on the dual-rate constant approach for a one compartment, first-order kinetic model (1CFOK), predicted values for both the acute toxic response and BCF based on these toxicokinetic constants were matched closely by observed values. Additionally, a strong correlation between the LC50 and BCF was found, which was expected based on their relationship to the balance between uptake and elimination and a consistent LR50 (lethal residue causing 50% mortality) among species. Predictions were made about the time to steady-state tissue concentrations with k2 values and how this would affect the results of the standard 10 day toxicity bioassay. Because acute TBT toxicity occurs at tissue concentrations 100 times lower than compounds exhibiting a narcosis mode of action, tributyltin is very toxic at low environmental concentrations, especially to organisms that have high uptake clearance and low elimination rate constants. Making predictions about toxicity based on uptake clearance and elimination rate constants in conjunction with the critical body residue will be helpful when choosing sensitive organisms for determining water and sediment quality criteria.

These are the loggerhead (Caretta caretta), green (Chelonia mydas), Kemp's ridley (Lepidochelys kempii), hawksbill (Eretmochelys imbricata), and leatherback (Dermochelys coriacea). The olive ridley (L. olivacea) occasionally occurs in the Atlantic. All are legally protected by the United States Endangered Species Act of 1973. Sea turtles are caught incidentally in shrimp trawls, and these captures have been identified as the major source of sea turtle mortality in the Gulf of Mexico and along the U.S. Atlantic coast. In these areas, Henwood and Stuntz (1987) estimated turtle capture and mortality rates for loggerheads, Kemp's ridleys, and green turtles from a variety of shrimp trawl data collected between 1973 and 1984. Turtle mortality was estimated at 9874 per year for loggerheads, 767 per year for Kemp's ridleys, and 229 per year for greens. Overall capture rates per year for these species were approximately four times higher than their mortality rate. Magnuson et al. (1990) considered the mortality of turtles in shrimp trawls to range from 5000 to 50,000 per year for loggerheads and 500 to 5000 per year for Kemp's ridleys. Information on actual observed captures and catch rates of sea turtles remains relatively scarce, especially regarding incidental catches in trawls equipped with a TED (Trawling Efficiency Device or Turtle Excluder Device) or BRD (Bycatch Reduction Device). The intent of this note is to estimate catch rates of turtles in shrimp trawls, excluding try nets, with and without TEDs in U.S. waters.

Several bycatch-reducing devices (BRDs) were compared to determine their effectiveness for reducing bycatch while maintaining prawn catch levels. A solid separator panel, a soft separator panel, and four secondary BRDs (fisheye, extended mesh funnel, Allerio Brothers grid, and square mesh panel) were attached to a Nordmore grid in a paired comparison experiment in the Hunter River prawn trawl fishery. The Nordmore grid and all secondary BRDs took less bycatch and more prawns compared with the commercially used blubber chute. Many commercial prawn fishers have voluntarily adopted the Nordmore grid because of its efficiency.

Although multiple life history stages of these species are widely represented throughout Florida waters, there are few areas around the state where marine turtles in the water have been studied in detail. We recognized Florida Bay a shallow embayment between the Florida Keys and the southern tip of the Florida peninsula as one area where information on marine turtles was sparse. Marine turtle studies there seemed imperative given that the health of the Florida Bay system has recently attracted an intense research effort to elucidate problems with nutrient loading, turbidity, hypersalinity, and seagrass dieoffs. This abstract summarizes part of an ongoing effort begun in 1990 to study the ecology of marine turtles in Florida Bay. Although we have recorded all four of the species known from shallow Florida waters in the Bay, this summary includes only information gathered from the two most common species, the loggerhead and the green turtle. We focus on then-distribution within the Bay, movements of individual loggerhead turtles, size-class structure of captured turtles, and the occurrence of the disease fibropapillomatosis.

The symposium was hosted by Florida Atlantic University, Mote Marine Laboratory, University of Central Florida, University of Florida, Florida Atlantic University and the Comite Nacional para la Conservation y Proteccion de las Totugas Marinas. The 17th was the largest symposium to date. A total of 720 participants registered, including sea turtle biologists, students, regulatory personnel, managers, and volunteers representing 38 countries. In addition to the United States, participants represented Australia, Austria, the Bahamas, Bonaire, Bermuda, Brazil, Canada, Colombia, Costa Rica, Croatia, Cuba, Cyprus, Dominican Republic, Ecuador, England, Guatemala, Greece, Honduras, India, Italy, Japan, Madagascar, Malaysia, Mexico, The Netherlands, Nicaragua, Peru, Philippines, Republic of Seychelles, Scotland, Spain, Sri Lanka, Switzerland, Taiwan, Turkey, Uruguay, and Venezuela. In addition to the 79 oral, 2 video, and 120 poster presentations, 3 workshops were offered: Selina Heppell (Duke University Marine Laboratory) provided "Population Modeling," Mike Walsh and Sam Dover (Sea World-Orlando) conducted "Marine Turtle Veterinary Medicine" and "Conservation on Nesting Beaches" was offered by Blair Witherington and David Arnold (Florida Department of Environmental Protection). On the first evening, P.C.H. Pritchard delivered a thoughtful retrospect on Archie Carr that showed many sides of a complex man who studied and wrote about sea turtles. It was a presentation that none of us will forget. The members considered a number of resolutions at the Thursday business meeting and passed six. Five of these resolutions are presented in the Commentaries and Reviews section of Chelonian Conservation and Biology 2(3):442-444(1997).

Prosecution of alleged poachers often requires knowledge of the species of seized eggs. Current methods using fatty acid profiles have not been able to resolve differences between eggs of loggerheads and the two ridley species. In this study, total DNA was extracted from turtle egg albumen by a modified proteinase K extraction method. An approximately 800 bp portion of the mitochondrial DNA was amplified by polymerase chain reaction, and the amplified fragment was digested with each of the restriction enzymes, Msp I and Alu I. The resulting restriction fragment length polymorphism patterns are not only species-specific, but can also be used to tell Atlantic and Pacific green turtles from one another.

Systematic monitoring for 24 consecutive seasons (1973-96) at the principal breeding site of French Frigate Shoals (FFS) has documented a significant increase in nesting females (Wetherall et al., 1997). However, fibropapillomatosis (FP), a debilitating and often fatal sea turtle disease, is currently an inhibiting factor to the full recovery of the Hawaiian green turtle population. The disease involves the formation of multiple fibrous tumors up to 25 cm in diameter on the eyes, in the mouth, and on all skin surfaces. Other sites affected less frequently include the carapace, plastron, and internal organs. The increase of FP and its epidemiological aspects in Hawaii have been documented in a major foraging aggregation at Palaau, Molokai. Some of the significant results of this work are summarized in this paper.

Since then, U.S. TED regulations have been expanded to include most countries which have an indigenous sea turtle population and export wild caught shrimp to the United States. Those countries must have sea turtle protection laws which equal those of the U.S., including the use of TEDs in their shrimp trawl fishery. In 1988, NMFS began an extensive program to provide training to host countries to train fishermen and fisheries managers in the construction and operation of TEDs.

Observers were placed on the vessels primarily to collect information needed for fisheries management or to document marine mammal interactions. Observers also documented sea turtle interactions with the fishing gear. Preliminary analysis of the data indicates that leatherbacks and loggerheads are the primary species encountered and that as many as 2,000 sea turtles are entangled or hooked annually. Most are released alive; but, no estimates of post release mortality are available.

In contrast, regional leatherback (Dermochelys coriacea) rookeries are less differentiated, perhaps due to the pelagic nature of this species. Analysis of data from microsatellite loci and mtDNA sequences shows restricted gene flow between Indo-Pacific and eastern Pacific leatherback nesting stocks. Two major nesting populations in Mexico and Costa Rica could not be distinguished based on mtDNA sequence data. To date, samples have been obtained from two leatherbacks caught in the Hawaii-based pelagic longline fishery. One had a haplotype only found in the Indonesian population, while the other had a haplotype only found in the eastern Pacific populations. Based on mtDNA sequences, 95% of the incidental take (n=24) of loggerheads (Caretta caretta) in the same longline fishery are of animals from Japanese nesting stock. Significant allele frequency differences at 2 microsatellite loci corroborated the mtDNA data, showing that the Japanese and Australian loggerhead rookeries are genetically isolated, and confirming that pelagic loggerheads in the north Pacific originate from the Japanese nesting stock. Mitochondrial DNA sequences from three green turtles caught in the longline fishery show that one is from local Hawaiian nesting stock (French Frigate Shoals), while two had a haplotype that has only been found in the eastern Pacific rookeries. The take of any eastern Pacific animals in the longline fishery is noteworthy, since the Hawaiian nesting population is considered Threatened, while the eastern Pacific populations are considered Endangered under the U.S. Endangered Species Act. Genetic stock assessment work is ongoing, with continued sampling of animals (including olive ridleys, Lepidochelys olivacea) caught in the longline fishery, and additional sampling of key nesting populations throughout the Pacific.

AN - 36387910; 6305 AB - PURPOSE: The amending of the fishery management plan (FMP) for monkfish in the exclusive economic zone (EEZ) along the North Atlantic coast from Labrador to Virginia and along the Outer Continental Shelf from Georges Bank to North Carolina is proposed. The monkfish (or goosefish) is a widely distributed benthic fish that is landed as a bycatch from groundfish and scallop fishing. Landings from bycatch and directed fishing have increased dramatically in recent years. Three alternatives are considered in this draft EIS; a No Action Alternative was considered but it was rejected because monkfish are overfished and state management alone would not provide adequate protection in federal waters. The proposed action would reduce mortality on a gradual schedule until it fell below the overfishing threshold and the biomass exceeded the biomass threshold. The proposed action would also impose a 45 percent reduction in landings during the fishing year ending June 30, 1997; a second 20 percent reduction would be imposed for the second year commencing on July 1, 1997. The fishery allocations would be held at 1997-98 levels for the third through sixth fishing years. The preferred alternative (Alternative 3) would manage monkfish as a component of the multispecies complex that includes cod, haddock, and yellowtail flounder. Vessels could use multispecies days-at-sea to target monkfish, regardless of their history in the monkfish fishery. Vessels without multispecies permits could qualify for a limited-access monkfish fishery permit. These qualifiers would receive an annual fleet day-at-sea allocation to target monkfish that is equivalent to the multispecies fleet allocation for groundfish. A 14-inch minimum tail size limit would be imposed in order to reduce mortality on small, immature monkfish. POSITIVE IMPACTS: Under the amendment, monkfish would be protected from the effects of overfishing. The limits on total allowable landings would reduce mortality to sustainable levels. NEGATIVE IMPACTS: The limits on landings and tail size would impose a temporary reduction in revenues until stocks rebuild.

AN - 19356494; 8732310 AB - The kinetics of excision of damaged purine bases from oxidatively damaged DNA by Escherichia coli Fpg protein were investigated. DNA substrates, prepared by treatment with H2O2/Fe(III)-EDTA or by gamma-irradiation under N2O or air, were incubated with Fpg protein, followed by precipitation of DNA. Precipitated DNA and supernatant fractions were analyzed by gas chromatography/isotope-dilution mass spectrometry. Kinetic studies revealed efficient excision of 8-hydroxyguanine (8-OH-Gua), 2,6-diamino-4-hydroxy-5-formamidopyrimidine (FapyGua) and 4, 6-diamino-5-formamidopyrimidine (FapyAde). Thirteen other modified bases in the oxidized DNA substrates, including 5-hydroxycytosine and 5-hydroxyuracil, were not excised. Excision was measured as a function of enzyme concentration, substrate concentration, time and temperature. The rate of release of modified purine bases from the three damaged DNA substrates varied significantly even though each DNA substrate contained similar levels of oxidative damage. Specificity constants (kcat/KM) for the excision reaction indicated similar preferences of Fpg protein for excision of 8-OH-Gua, FapyGua and FapyAde from each DNA substrate. These findings suggest that, in addition to 8-OH-Gua, FapyGua and FapyAde may be primary substrates for this enzyme in cells.

Fish livers were examined for toxicopathic lesions and analyzed for selected chlorinated hydrocarbons (CHs) such as PCBs, DDTs, chlordanes and dieldrin; sediment and fish stomach contents were analyzed for polycyclic aromatic hydrocarbons (PAHs) and CHs; and bile was analyzed for PAH metabolites. Sediment concentrations of PAHs, PCBs, and DDTs; bile concentrations of PAH metabolites; and liver concentrations of PCBs, dieldrin and chlordanes were generally significantly higher at all San Francisco Bay sites compared to the Bodega Bay reference site. For both species, hydropic vacuolation of biliary epithelial cells was the most prevalent liver lesion detected and was statistically associated with sediment and tissue concentrations of PAHs or their metabolites, PCBs, DDTs, chlordanes and dieldrin. Temporal trends analyses showed that at Hunters Point, sediment PAHs and CHs increased between 1984-1991, while liver concentrations of CHs decreased. Liver concentrations of dieldrin in starry flounder decreased at all three San Francisco Bay sites.

In the early 1960s, a one-dimensional, radiative-convective equilibrium model was developed as the first step towards the development of a three-dimensional model of climate. Incorporating not only the radiative but also the convective heat exchange between the earth's surface and the atmosphere, the model overcame the difficulty encountered by the earlier approach of surface radiative heat balance in estimating the magnitude of greenhouse warming. By the 1970s, a three-dimensional, general circulation model (GCM) of the atmosphere, coupled to a very idealized ocean of swamp-like wet surface, had been used for studies of greenhouse warming. Despite many drastic simplifications, the GCM was very effective for elucidating the physical mechanisms that control global warming and served as a stepping stone towards the use of more comprehensive, coupled ocean-atmosphere GCMs for the study of this problem.

The model has five components: severity of effect, degree of response, bioassay variability, consistency, and number of measured endpoints. The model can reliably reduce an array of ambient toxicity data into a site-specific metric that is appropriate for comparisons with other metrics, such as Index of Biotic Integrity (IBI) or community diversity indices. The model is tolerant of variable amounts of data between stations. It does not generate probability limits without repeated sampling. The model can identify trends between sampling stations and document where chemical contamination is contributing to community impacts as well as where toxicological impacts are not likely to be contributing to observed population level impairment. The model was evaluated with field/laboratory data. Test sites were located in tributaries of Chesapeake Bay watersheds that are impacted by industrial, urban, and agricultural land use patterns. The toxicological risk scores correlate with fish community health metrics. The strongest correlations were between sediment toxicity risk and bottom trawl fish community diversity index.

AN - 36401194; 6236 AB - PURPOSE: The establishment of a confined disposal facility (CDF) in Newark Bay to receive contaminated materials dredged from the New York-New Jersey Harbor is proposed. The project area is defined as the harbor waters contiguous to New Jersey, including Newark Bay, the Arthur Kill, and Kill Van Kull. The dredging of shipping channels and berthing areas in the Port of New York and New Jersey is necessary to maintain sufficient water depth for safe navigation and maintenance of a viable shipping industry. Sediment buildup, a result of the natural shallowness of the port and high sedimentation rates, clogs the port and makes it impossible to accommodate deeper-draft vessels. Up to 6,000 cubic yards (cy) of sediment must be dredged annually to maintain safe water depths. In recent years, dredging operations have been hampered by the lack of disposal sites for dredged materials. The proposed action would involve the construction of sub-aqueous borrow pits in Newark Bay as a short-term alternative for the disposal of contaminated materials considered unsuitable for ocean disposal. The pits would be located on the west side of Newark Bay near the Port Newark-Port Elizabeth terminals. The CDF would have a combined capacity of three million cy. Other alternatives under consideration include the construction of only one of the CDFs, the construction of a CDF on the east side of Newark Bay, the construction of CDF on both sides of the Bay, and a No Action Alternative. POSITIVE IMPACTS: The CDF would ensure that port facilities would continue to operate while a long-term disposal plan for contaminated dredged material is being developed. The CDF would operate from September 1997 through the year 2000, at which point a long-term plan would be put into effect. NEGATIVE IMPACTS: The proposed action would disturb two percent of the Newark Bay's bottom shoal area and kill some benthic organisms and demersal fish. Turbidity would increase at the disposal sites.

AN - 79273920; 9291500 AB - We have developed an estrogen sensitive reporter gene assay and report here on its responsiveness to steroid hormones and several estrogenic contaminants, including pesticides and polychlorinated biphenyls (PCBs), GH4C1 rat pituitary cells were stably transfected with the reported gene ERE-TK-Luc which contains a luciferase gene under the transcriptional regulation of the Xenopus vitellogenin estrogen response element (ERE) and clones stably expressing ERE-TK-Luc were isolated. The sensitivity of the assay was determined by dose response with the endogenous ligand 17 beta-estradiol. An EC50 of 4.5 +/- 1.2 x 10(-11) M was determined for this compound. Natural and synthetic hormones such as dexamethasone, aldosterone, and thyroxine did not induce luciferase activity, whereas 10(-8) M diethylstilbestrol induced luciferase activity to a maximal equal to 17 beta-estradiol, indicating that transcription of the luciferase gene is primarily regulated through the endogenous estrogen receptors. The pesticide o,p'-DDT was found to be estrogenic at concentrations as low as 10(-7) M. Of the three PCBs assayed, 2',4',6'-trichlorobiphenyl and its hydroxylated metabolite 4O H-2',4',6'-tricholorbiphenyl were estrogenic at 10(-7) M, whereas 2,4,4'-trichlorobiphenyl did not induce luciferase activity. Lastly, the GH4C1 ERE-Luc reporter gene assay was modified to utilize a cell permeant luciferin and 96 well format suitable for multiple and complex samples and generation of detailed dose response data.

AN - 78973004; 9131593 AB - Domoic acid induces a time-dependent neuroexcitotoxic effect in neonatal rats characterized by hyperactivity, stereotypic scratching, convulsions, and death with observable behaviors occurring at exposures 40 times lower by body weight in neonates than reported in adults. Low doses of domoic acid (0.1 mg/kg) induced c-fos in the central nervous system which was inhibited in part by 2-amino-5-phosphonovaleric acid, an NMDA receptor antagonist. Domoic acid caused no evidence of structural alteration in the brain of neonates as assessed by Nissel staining and cupric silver histochemistry. Domoic acid induced reproducible behavioral effects at doses as low as 0.05 mg/kg and induced seizures doses as low as 0.2 mg/kg. Determination of serum domoic acid levels after 60 min exposure indicated that serum levels of domoic acid in the neonates corresponded closely to the serum levels that induce similar symptoms in adult rats and mice. We conclude that neonatal rats are highly sensitive to the neuroexcitatory and lethal effects of domoic acid and that the increased sensitivity results from higher than expected serum levels of domoic acid. These findings are consistent with other findings that reduced serum clearance of domoic acid is a predisposing factor to domoic acid toxicity.

In these tests the axial load on the column was held nearly constant while cyclic lateral loads were applied to cause column deformations in the inelastic range. The data in this report were obtained from test programs in the United States, Canada, New Zealand, and Japan. Synopses of each test program are presented and the geometric and material properties of each column test specimen are summarized. Plots of lateral load vs. lateral deflection are also shown for each specimen. The lateral load-lateral deflection histories for all specimens are presented in digital format on a computer disk. Much of this data has only been available in analog format, and is presented for the first time in digital format in this report.

Carbon dioxide is reduced quantitatively to graphite on iron fibers via manganese metal, and the Fe-C fibers are melted into a bead suitable for AMS. Pretreatment, reduction and melting processes occur in sealed quartz tubes, allowing parallel processing for otherwise time-intensive procedures. Chemical and isotopic ( (super 13) C, (super 14) C) blanks, target yields and isotopic fractionation were investigated with respect to levels of sample size, amounts of Fe and Mn, pretreatment and reduction time, and hydrogen pressure. With 7-day pretreatments, carbon blanks exhibited a lognormal mass distribution of 1.44 mu g (central mean) with a dispersion of 0.50 mu g (standard deviation). Reductions of 10 mu g carbon onto targets were complete in 3-6 h with all targets, after correction for the blank, reflecting the (super 13) C signature of the starting material. The 100 mu g carbon samples required at least 15 h for reduction; shorter durations resulted in isotopic fractionation as a function of chemical yield. The trend in the (super 13) C data suggested the presence of kinetic isotope effects during the reduction. The observed CO (sub 2) -graphite (super 13) C fractionation factor was 3-4% smaller than the equilibrium value in the simple Rayleigh model. The presence of hydrogen promoted methane formation in yields up to 25%. Fe-C beaded targets were made from NIST Standard Reference Materials and compared with graphitic standards. Although the (super 12) C ion currents from the beads were one to two orders of magnitude lower than currents from the graphite, measurements of the beaded standards were reproducible and internally consistent. Measurement reproducibility was limited mainly by Poisson counting statistics and blank variability, translating to (super 14) C uncertainties of 5-1% for 10-100 mu g carbon samples, respectively. A bias of 5-7% (relative) was observed between the beaded and graphitic targets, possibly due to variations in sputtering fractionation dependent on sample size, chemical form and beam geometry.

It was moved intact in May 1977 to its present site at NIST in Gaithersburg, MD. The purpose of the stone test wall is to study the performance of stone subjected to weathering. It contains 2,352 individual samples of stone, 2032 of which are domestic stone from 47 states, and 320 stones from foreign countries. Over 30 distinct types of stones are represented, some of which are not commonly used for building purposes. There are many varieties of the common types used in building, such as marble, limestone, sandstone, and granite. Unexposed specimens have been stored indoors at room temperature and humidity facilitating the determination of weathering effects. The type and extent of degradation observed in the stone specimens varies greatly, ranging from deep erosion to mild scaling (sugaring). In general, specimens of stones commonly found in buildings and monuments exhibited minor or slight degradation, usually some discoloration or scaling. The types and extent of degradation are described, with emphasis on common building stones. Also, ways to quantify the amount of degradation using computerized imaging techniques are discussed.

Most are circular truncated cones with steep flanks and relatively large flat summit plateaux. Most, too, have prominent offset craters or calderas, nearly all of which are displaced from the volcano centres towards the axis of the Juan de Fuca Ridge. The explanation for this may lie with plate motion which transports volcanoes away from magma sources beneath the lithosphere leaving the supply conduits first to lag behind then to become abandoned so as to form ridgeward collapse structures. From this model it is inferred that individual volcanoes were active for approximately 50 000 years and that most cone building eruptions took place during the first thousand years or so, with associated hydrothermal activity temporarily rivalling the present-day early time-averaged hydrothermal output along the entire ridge axis.

Formulae are derived for their standard errors from the covariances of geopotential field models. Numerical examples are presented for pairs of the altimeter-bearing satellites TOPEX/Poseidon, ERS 1, and Geosat, using the error matrices of recent gravity models. The DSC, connecting separate missions, will play an increasingly important role in oceanography spanning decades only when its nonoceanographic signals are thoroughly understood. In general, the content of even the long-term averaged DSC is more complex then their single satellite crossover (SSC) counterpart. The LLC, as the spatial spectra for the geopotential-caused crossover effects, discriminate these source-differences sharply. Thus, the zero-order LLC in DSC data contains zonal gravity information not present in SSC data. In addition, zero- and first-order LLC of DSC data can reveal a geocenter discrepancy between the orbit tracking of the separate satellite missions. For example, DSC analysis from orbits computed with JGM 2 show that the y-axis of the geocenter for Geosat in 1986-1988 is shifted with respect to T/P by 6-9 cm towards the eastern Pacific. Also, where the time-gap is necessarily large (as between, say, Geosat and T/P missions) oceanographic (sea-level) differences in DSC may corrupt the geopotential interpretation of the data. Most importantly, as we illustrate, media delays for the altimeter (from the ionosphere, wet troposphere and sea-state bias) are more likely sources of contamination across two missions than in SSC analyses. Again, the LLC of zero order best shows this contrast. Using the higher-order LLC of DSC for both Geosat-T/P and ERS 1-T/P as likely representation of geopotential-only error, we show by comparison with the predicted standard errors of JGM 2 that the latter's previously calibrated covariance matrix is generally valid.

These observations indicated the persistence of slick features associated with the grounding on February 15, 1996 of the Sea Empress anchor at the entrance of the Milford Haven estuary and the resulting massive oil spill that followed. RADARSAT, ERS-1, and ERS-2 SAR images revealed the evolution of these features from February 22 to February 26, 1996. The feature tracking Maximum Similarity Shape Matching method (MSSM) developed at the University of Delaware College of Marine Studies (CMS) was applied to the pair of ERS SAR images. MSSM calculated drift speeds of about 10 cm/s. Observations of the slick pattern evolution in the SAR imagery were compared to available reports of ground conditions. Deformation of the slick features was also evident in the SAR data throughout the five-day period.

Obtaining data from offshore platforms opens opportunities for scientists, businesses, and governments to collaborate and share important and timely data. Strong interest has arisen among these communities to establish a worldwide program coordinating the use of offshore platforms for research and technology development. As a result, an international workshop was held in Bergen, Norway in 1996 which identify scientific and environmental research opportunities and the needs of establishing such a program.

The NADP/AIRMoN program is designed to provide deposition information required to evaluate the progress of the emissions reductions mandated by the CAAA. NADP/AIRMoN started in October, 1992 to establish deposition levels prior to Phase I emission rollbacks in 1995. It will be necessary to continue sampling at least until early in the next century to determine the full impact of the CAAAs on deposition, which will not occur until after 2000.

Five North American sturgeons (shortnose, Gulf, pallid, Alabama, and green sturgeon) are listed as endangered or threatened by management authorities. Managers have instituted fishery closures for the three other species of North American sturgeons (Atlantic, white, and shovelnose) and paddlefish because of low stock abundance at some point in this century. Reproductive potential in four species I examined (Atlantic, white, and shortnose sturgeon and paddlefish) is more sensitive to fishing mortality than it is for three other intensively-fished coastal species in North America: striped bass, winter flounder, and bluefish. The sturgeons and paddlefish are generally longer-lived than the three other coastal species, and also have an older age at full maturity, lower maximum fecundity values, and older ages at which 50% of the lifetime egg production is realized with no fishing mortality.

AN - 17167304; 4472708 AB - During the years 1970-87, the North Atlantic hurricane basin had experienced a relative lull in overall tropical cyclone activity. The heightened activity in 1988 and 1989 was followed by a marked downturn in activiy from 1991-94. As a result of the resumption of the below-normal activity, primarily attributed to wind anomalies driven by the highly anomalous, long-lasting warm sea-surface temperature event El Nino in the tropical Pacific, the notion the Atlantic basin had entered a high-activity regime was discarded. The warm event in the Pacific finally ended in early 1995 and was followed by one of the most active hurricane seasons in the Atlantic on record. The chief issue being addressed in the current study is whether or not the activity of the 1995 season was simply an anomalous `spike' or a harbinger of multi-decadal-scale climate shifts signaling the probability of greater activity over the next 10-20 years. Long-term climate changes are typically associated with slowly evolving fluctuations in the world's oceans. Some of these oceanic fluctuations will be examined and related to Atlantic tropical cyclone activity. JF - Climate Change and Climate Variability in Atlantic Canada.

Fish were collected as part of the SEA cruises in the fall of 1995 and were frozen immediately and then shipped to Galveston for analysis. Fatty acid signatures of herring, pollock, and tomcod were consistent with previously reported data, Three different species of sole (English, rock, and flathead) were also consistent with previously reported data for yellowfin sole. Detailed analyses of individual rock fish suggest that this species may exhibit trends in some specific fatty acids (20:5 n-3, 22:6 n-3) which differ from herring or pollock.

The system includes data on chinook salmon (Oncorhynchus tshawytscha), chum salmon (O. keta), coho salmon (O. kisutch), pink salmon (O. gorbuscha), sockeye salmon (O. nerka), and steelhead (O. mykiss). Each ArcView project is catagorized into salmonid spawning escapement, hatchery releases, and presence/absence tabular data. Salmonid spawning escapement data sets are further divided by observation type (i.e., dam counts, fish per mile, etc.) and linked to spatial data sets (i.e., coverages - digitized geographic files) representing streams and rivers within the Columbia River Basin. Additional coverages (dams, hatchery locations, state boundaries, and land ownership) have been incorporated into each project to provide geographic reference and permit data analysis. This desktop GIS allows scientists and managers to view salmonid population characteristics and geographic features simultaneously over varying spatial scales. The addition of detailed habitat information (e.g., land use, roads/mile, water temperatures) in the future will enable scientists to identify how past and future watershed activities will affect salmonid populations in the Northwest.

N1 - Last updated - 2015-03-24 ER - TY - BOOK T1 - Predictions of Antarctic climatic and ecological response to global warming and ozone depletion AN - 16548573; 4365318 AB - This paper summarizes predictions and observations of Antarctic climatic change and considers the potential ecological consequences of global warming and ozone depletion. General circulation models predict a weakening of the thermohaline circulation in the Weddell and Ross Seas within the next 140 years, in response to a quadrupling of the atmospheric concentration of CO sub(2). Models also predict that the equilibrium response of surface air temperatures, to a doubling of the atmospheric concentration of CO sub(2), would be enhanced by the poleward retreat of sea ice around the Antarctic continent. An additional concern is the chlorine-catalyzed, springtime destruction of stratospheric ozone, which causes an increased penetration of biologically-damaging ultraviolet-B radiation. Given the large uncertainties in the temporal and spatial response of the Antarctic marine ecosystem to seasonal increases in ultraviolet-B radiation, predicted weakening of the thermohaline circulation, potential changes in the rates of melting or calving of the ice sheet and changes in the extent of the ice-edge, we strongly advocate a precautionary approach to Antarctic resource management. In addition, we provide a series of recommendations for research, monitoring and IWC collaboration.

No genetic information is available to define the population structure, but distributions of sightings, strandings and incidental takes suggest that three population units may exist: Gulf of Maine, Gulf of St Lawrence and Labrador Sea. The most recent abundance estimate, 27,200 (CV = 43%), is from a line-transect survey conducted during summer in waters from Virginia to the Gulf of Maine, lower Bay of Fundy and eastern Scotian slope region. White-sided dolphins have been caught in otter trawls and sink gillnets off the northeast coast of New England, in offshore US pelagic drift gillnets and mackerel off-bottom trawls, in groundfish sink gillnets from the Bay of Fundy, Newfoundland and Labrador Seas and in salmon gillnets from the Labrador Sea. For 1990-1995, the estimated average annual bycatch in US fisheries was 181 animals (CV = 25%). No estimates are available on bycatch in Canadian fisheries. Little information exists on the life history and feeding ecology of this species in the northwest Atlantic.

In both methods, nitrogen gas, the end product of denitrification, was measured directly by gas chromatography. The in situ approach allowed measurement of denitrification directly over short time intervals but its use was limited to shallow depths. Denitrification rates measured with in situ chambers agreed well with those from in vitro intact cores when temperatures in the estuary remained constant. However, the two methods could not be accurately compared during the spring when temperature increased rapidly, because of the 4-day pre-incubation time needed for sparging for the in vitro method. In vitro denitrification rates ranged from ca 40 to 135 mu mole N sub(2) m super(-2) h super(-1) in October 1993 and from 66 to 428 mu mole N sub(2) m super(-2) h super(-1) in May and July 1994. Oxygen consumption rates in these experiments ranged from 0.71 to 3.0 mmole O sub(2) m super(-2) h super(-1). Denitrification rates tended to decrease along the flow axis but differences among stations were usually not significant. In situ N sub(2) accumulation rates ranged from 45 mu mole N sub(2) m super(-2) h super(-1) in dark chambers during October 1993 up to apparent values of 2,100 mu mole N sub(2) m super(-2) h super(-1) in May 1994, immediately after the water temperature had rapidly increased to 27 degree C. These calculated values included gas-solubility corrections due to the water-temperature increases. In situ measurements of denitrification rates in transparent chambers were 76-79% higher than rates measured in a similar dark chamber. The results suggest that denitrification is an important sink for nitrogen in Old Woman Creek estuary and that environmental conditions such as temperature, light, and available substrate affect denitrification rates.

In total, coastal areas comprise only 8% of the worlds surface area but they are extremely attractive for human settlement and social activity due to their wealth of natural resources and amenities. They are biologically highly productive, hubs of industrial infra-structure and economic growth, and highly desirable for tourism and recreation. It is this very attraction that has led to intense pressures on the diverse and valuable resources of the coastal regions; pressures that are likely to increase.

Climate-change effects interact with those of pervasive overfishing diminishing nursery areas, and extensive inshore and coastal pollution. Globally, marine fisheries production is expected to remain about the same; high-latitude freshwater and aquaculture production are likely to increase, assuming that natural climate variability and the structure and strength of ocean currents remain about the same. The principal impacts will be felt at the national and local levels as species mix and centers of production shift. The positive effects of climate change, such as longer growing seasons, lower natural winter mortality, and faster growth rates in higher latitudes, may be offset by negative factors such as changes in established reproductive patterns, migration routes, and ecosystem relationships'.

Lysosomal membrane labilization period and lipofuscin content of digestive tissue were significantly decreased and increased, respectively, after 30 days of exposure to PAHs but not PCBs. NADPH-ferrihemoprotein reductase activity in the digestive tissue was significantly increased after 30 days exposure to both PAHs and PCBs, whereas catalase activity was significantly increased only after exposure to PCBs. Neutral lipid content and gamma-glutamyl transpeptidase activity of digestive tissue of mussels were significantly increased and decreased, respectively, after 30 days exposure to both PAHs and PCBs when compared to untreated mussels, but were not significantly different when compared to mussels treated with com oil representing the vehicle control. Exposure to PAHs induced peroxisome proliferation in the digestive tissue of M. edulis complex. The observed cytochemical responses in the digestive tissue of M. edulis complex exposed to PAHs and PCBs in the laboratory are comparable to the cytochemical responses observed in the digestive tissue of mussels collected in the field from sites contaminated with predominantly PAHs and PCBs.

Sediment resuspension and subsequent redeposition during manganese-nodule mining is predicted to be the primary impact on benthic communities living on the abyssal seafloor. Sediment redeposition could adversely affect abyssal benthic communities through entombment, spatio-temporal changes in recruitment patterns, or through starvation caused by food dilution and obstructed feeding. NOAA started the BIE with baseline studies in July 1993 with the deployment of a transponder net and current meters, and by conducting side scan sonar/camera surveys, and benthic sampling. Following the baseline activities the study area was blanketed with varying thicknesses of sediment using the Disturber. In the BIE, the Disturber was towed 49 times through a 150-m-x-3,000-m tow zone resuspending 4,000 m super(3) of wet sediment. The bulk of the resuspended material was transported north of the tow zone by northerly currents at the time of disturbance. The majority of the discharged sediment settled quickly as a sediment-laden fluid flow.

Users can interpret climate outlooks to assess the risk to water resources of extreme meteorological conditions and of variability in general. One important approach uses historical meteorology record segments with hydrological, limnological and other models to simulate hydrological possibilities for the future (preserving observed spatial and temporal relationships). The meteorological possibilities are weighted to be compatible with climate outlook probabilities. The corresponding weighted hydrological possibilities are used to infer water resource probabilities and other parameters. The weights are determined by constructing boundary equations for the weights to match climate outlooks, setting the relative importance of each equation in case incompatibilities arise and solving them for physically relevant values. Their solution becomes an optimization problem for the general case. An example illustrates the concepts and method. JF - SUSTAINABILITY OF WATER RESOURCES UNDER INCREASING UNCERTAINTY.

For floating portions of the spilled oil that are constrained to remain on the surface, the two-dimensional kinematics of the flow patterns can be used to identify locations for flotsam collection. In areas where there are strong "flow convergencies" a Lagrangian view shows the surface water moving towards a common region. As a result, the concentrations of floating material will increase where convergence zones are found. In coastal communities these areas are typically referred to as "tidal rips" or "rips". In some regions these convergence zones are persistent enough to have common names associated with them. The convergence zones are always areas for flotsam collection. A high-resolution now-casting numerical model has been implemented for San Francisco Bay to assist oil-spill prevention and response. Thirty-six hours of now- casting high-resolution numerical model results are available centered around the present time. The current patterns from these model results can be further analyzed to provide information that identifies areas of strong convergence. Results of this kinematic analysis can be used to identify likely collection areas for floating oil and to provide location maps for the effective placement of recovery equipment. Convergence zones are typically associated with barotropic flow over large bathymetry variations or density fronts at interfaces where oceanic and fresh water mix. These analysis techniques were further developed and tested in San Francisco Bay to strengthen local oil-spill response planning activities. During an actual spill caused by the Cape Mohican in San Francisco Bay (late October 1996), the planning response for clean up efforts and the development of insights on the movement of oil patches were enhanced by the results of the current pattern analysis.

PORTS is installed in Tampa Bay, New York/New Jersey Harbor, Houston/Galveston, and San Francisco Bay. PORTS consists of real-time observations of ocean conditions and weather, computer model nowcasts and forecasts of ocean fields, and dissemination of data via a telephone voice data response system and Internet. PORTS information ensures that an adequate margin of safety is available to larger and larger ships in channels which are being deepened but not significantly widened. PORTS provides information permitting shippers to load their vessels to take full advantage of real-time water levels and channel improvements. PORTS information guides hazardous materials spill prevention and response as well as effective ecosystem health management. The San Francisco Bay PORTS is the model for a future National PORTS. That model is an extensible PORTS based on an Information Hub Concept (InfoHub) which will permit PORTS to adapt to evolving user needs. The extensible PORTS provides standard sensor interfaces to encourage the addition of non-NOAA sensors to the system. A data base provides a broad user community with access through downloadable applications and applets on Internet. PORTS provides information broadcast to shipboard vector and raster Electronic Chart and Information Display Systems and a Lockheed Martin/Rensselaer Polytechnic Institute Navigation and Piloting Expert Systems (NPES). An open architecture design will encourage commercial and academic partners to participate in National PORTS development. JF - PROCEEDINGS OF OCEANS '97. VOLUME 2.

Previously, variation in bioavailability for some Great Lakes sediments compared to a soil material was nearly a factor of 10 after carbon normalization. Because a soil might not truly represent sedimentary materials, sediments and soils were gathered from several locations in the United States, Canada, and Finland. The accumulation kinetics of the amphipod Diporeia spp. were measured for pyrene, benzo[a]pyrene (BaP), 2,4,2',4'-tetrachlorobiphenyl (TCBP), and 2,4,5,2',4',5'-hexachlorobiphenyl (HCBP) sorbed to sediments and soils. The organic carbon content of the sediments ranged from 0.45-21.2% and 32.2-45.0% for soils. The bioavailability, measured as the uptake clearance (amount of source compartment cleared of contaminant per mass of organism per hour), was controlled by the amount of organic carbon, particularly for the chlorinated biphenyls. However, for polycyclic aromatic hydrocarbons (PAH), bioavailability was controlled more by the organic carbon polarity represented by the carbon/nitrogen ratio of the sediment. PAH bioavailability increased as the ratio increased; thus, the more nonpolar the organic matter, the more available the compound. This polarity did not account for any of the chlorinated biphenyl bioavailability. The amount and type of mineral matrix of the sediment did not influence the bioavailability for either compound class. In addition, the amount of oxygen in the sediment was correlated with the bioavailability for BaP after carbon normalization.

Hawksbill turtles are also occasional visitors. We compiled data sets containing sightings, strandings, and fishing gear entanglements of the sea turtles in the northeastern United States, and used the most reliable and complete data sets to develop distributional plots of the turtles by species, fishery, and season. We reviewed fishery-dependent data from the National Marine Fisheries Service (NMFS) foreign observer, sea sampling, and marine mammal exemption programs, and swordfish fishery logbooks. Fishery-independent data sets examined were the NMFS northeast bottom trawl survey, the Manomet observer program, the cetacean and turtle assessment (CeTAP) program, the marine mammal surveys, the sea turtle stranding and salvage network (STSSN), and museum and aquarium collections. We used the CeTAP, Manomet, STSSN, and swordfish logbook data for analyses of loggerhead and leatherback turtles, since they were the most reliable and complete. Of the various fishery data sets we compiled, four fisheries caught sea turtles: the swordfish longline fishery, swordfish gillnet fishery, trawl fishery, and crab/lobster fishery. The longline fishery had the most turtles recorded as taken. Captures of loggerheads and leatherbacks in the 1992 longline fishery for swordfish were concentrated along the 100-fathom depth contour, which coincided with the concentration of longline effort. Bycatch of leatherback turtles was significantly higher when the longliners targeted sharks, and loggerhead bycatch was significantly higher when the longliners targeted swordfish or tunas. Characteristics of the longline fishery that seem to affect bycatch of loggerheads and leatherbacks include gangion length, number of lights per kilometer, and number of hooks per kilometer. Leatherback bycatch in the gillnet fishery was also higher when the gillnets had a larger mesh size, were fished in deeper waters, and had shorter net lengths. Investigation is needed into how characteristics of the longline fishery change depending on the species targeted (swordfish, tunas, or sharks), since the number of turtles captured is apparently influenced by how the sets are made. Also, we found an overall lack of standardization in the data sets pertaining to bycatch of sea turtles that made comparisons and interpretations difficult. We found the use of a geographic information system helpful in determining the general distributions of sea turtles in northeast U.S. waters, although specific habitats used by the turtles still need to be identified and evaluated. Finally, we recommend that latent survival studies be conducted on turtles entangled in fishing gear to determine the population level effects of bycatch.

This bathymetry utilizes the entire archive of historic hydrographic data assembled since 1903 in the U.S. and Canada. Details of bottom configuration for the shallow (< 12 m) western portions of Lake Erie are highlighted using a 1-meter contour interval. The islands and reefs bordering and lying within the western basin have bedrock cores which are erosional remnants of the more resistant upper Silurian and lower Devonian dolomites and limestones. Overdeepened channels between the islands have been sites of postglacial nondeposition, and probably erosion, due to intense wind-driven water circulation through these restricted passages. The Pelee-Lorain Ridge is interpreted as a late Wisconsinan end moraine upon which sand deposits have been concentrated. The Point Pelee Ridge is apparently a morainic ridge, capped by sand deposits transported in part by longshore drift converging on Point Pelee. A fan-shaped feature with a surface depth of 10-15 m, which extends to the east of Point Pelee Ridge, may be a former shoreline delta of the Detroit River. This fan-shaped feature may have formed following opening of the Port Huron outlet about 4000 yr bp when the new River was actively eroding its channel and bringing a heavy load of sediment into Lake Erie - although subaqueous deposition of fan sediments is a possible alternate explanation. Sculptured drift-like features interpreted as relict spits extend northwestward and southeastward from the bedrock reefs in the western basin off Locust Point. Channels on the floor of the western Lake Erie basin underlying the main shipping lanes have been excavated by propeller wash where ship traffic increases speed, resulting in resuspension of bottom sediments. Dumpsites for dredge spoils excavated from channels are expressed in the bathymetry by a distinctive hummocky pattern in two areas.

The sharp break between prolonged periods of high (pre-1965) and low (post-1965) haddock abundance suggests differing levels of stock productivity, consistent with a surplus production model incorporating a nonlinear predation rate. This model and another model without a prediction term were fit to haddock data to evaluate various rebuilding strategies with two performance measures: the sums of discounted yield and discounted revenue. The former model provided plausible parameter estimates for the entire data set (1931-1993) whereas the latter model provided plausible estimates only for years of low productivity (1976-1993). The presence of multiple equilibria in the former model resulted in minor shifts of F, potentially producing large shifts in projected future biomass. For either model, levels of F that maximize either yield or revenue were lower than the recently adopted target level of F sub(0.1) identical with 0.24. Recent low production provides impetus for managers to consider a variety of plausible stock production models, and the uncertainty of production dynamics, in choosing rebuilding strategies.

The methodology involved the use of bootstrap resampling to allow computation of confidence bounds on model comparison measures, and an inverse weighting to accommodate pooling of data from several field experiments. Mention was made that it would be useful to explore alternative choices for the primary within-regime statistic selected for defining the differences to be seen between the modelled and observed concentration values. In this discussion, we explore the differences to be seen in using the Robust Highest Concentration versus the median of the upper quartile of values as the primary statistic for defining differences between modelled and observed concentration values, and assess which might be less sensitive to natural variability (or uncertainty).

Wind speeds up to 55 m s super(-1) at the meter closest to the storm path were associated with recorded mean current speeds up to 94 cm s super(-1). The greatest water speeds, however, were transient motions from the wind waves. These motions caused major changes to the bottom and to objects lying on it. Direct and remotely sensed observations showed an increasing degree of turbulence in the water as the hurricane approached, stirring both air bubbles and bottom sediment throughout the water and mixing the water so that vertical shear in the current was suppressed. Thus, beneath the strong wind stress there was not a mean water flow in the direction of the wind at the surface and a flow in the opposite direction near the bottom, as had been indicated in previous studies. In later stages of the storm passage, the current developed an eastward component, running against the incoming wind waves, which may have contributed to the evolution of the most extreme conditions.

Although such studies have been performed previously, this work is the first where the deliberate tracers, in conjunction with carbon system parameters, are used to quantify changes in water column carbon inventories due to air-sea exchange and net community metabolism. The horizontal dispersion and the gas transfer velocity were determined over a period of 2 weeks from the change in both the concentrations and the concentration ratio of the two injected trace gases, sulfur hexafluoride (SF sub(6)) and helium-3 ( super(3)He). The second moment of the patch grew to 1.6 x 10 super(3) km super(2) over a period of 11 days. The gas transfer velocity, normalized to CO sub(2) exchange at 20 degree C, was 8.4 cm hr super(-1) at an average wind speed, U sub(10), of 4.4 m s super(-1) for the duration of the experiment, which is in good agreement with empirical estimates. Remineralization rates exceeded productivity, causing an increase in dissolved inorganic carbon of about 1 mu mol kg super(-1) day super(-1) in the water column. During this period of senescence, 80% of the increase in inorganic carbon is attributed to community remineralization and 20% due to invasion of atmospheric CO sub(2).

Fry were fed high fat (23%) or low fat 3% diets at high (satiation) and low (one half satiation) ration levels for 7 months prior to the start of the intake experiment. This pre-treatment produced fish averaging 22 g with 11.3% (high fat diet) and 5.4% (low fat diet) body fat when fed to satiation. Experiment 1 had a 2 x 2 factorial design where duplicate groups of 20 fish from the high ration groups 22 g) were fed high (16%) or low (4%) fat diets twice daily to satiation six days/week for 3 weeks. Daily feed intake was recorded. The same protocol was used in Experiment 2 on fish (40 fish/tank) from the smaller, low ration groups (11 g). Feed intakes on day one, cumulative feed intakes after 21 days and plasma levels of insulin and insulin like growth factor 1 (IGF-1) were compared using Two-Way ANOVA with initial whole body fat and dietary fat as the independent variables. In both experiments, high body fat led to significantly lower feed intake on day one and after 21 days of feeding. High dietary fat level caused greater intake on day one, but by the end of the experiments, this effect was not significant suggesting some adaptation to the diets. Insulin in plasma showed greater response to dietary fat (high fat diets causing higher insulin levels), whereas IGF-1 responded more to body fat level (high body fat let to higher IGF-1) levels). Our results show that in both large and small juvenile chinook salmon, adiposity plays a role in regulation of feed intake, and that adiposity appears to interact with IGF-1. Dietary fat levels had transient effects on intake, but plasma insulin levels consistently reflected the dietary fat levels.

However, killer whale records are rare from the Gulf of Mexico (Gulf). The first reported Gulf record was a stranding from Cuba in 1886 that may have been a killer whale but was apparently later identified as Pseudorca crassidens (Cuni 1918). Katona et al. (1988) reviewed ten published and previously unpublished Gulf records from 1921 through 1987 (Table 1). Four stranding records consisted of a single tooth in 1921, a skull in 1948, and one animal in 1956, all from Florida; and an unconfirmed single animal from Texas in 1969. Six sighting records were included from off Florida in 1921 and 1979; and Texas in 1951, 1985 (two sightings) and 1987. The significance of these records was not clear because of their paucity and wide spatial and temporal distributions; that is, are killer whales only occasional inhabitants of the Gulf, or do they inhabit it regularly?

We found that the meltwater input during deposition of Heinrich layer 4 resulted in a 1-2 kyr temperature decrease of about 2 degree C and a salinity decrease in the range of 1.5ppt-3.5ppt between 40 and 50 degree N. Sites above 50 degree N did not experience significant salinity variations. A much larger area was affected by the reduction in sea surface temperature. The amplitude of the sea surface temperature shift was, however, much smaller than the atmospheric temperature changes over Greenland at GISP and GRIP sites.

Following a maximum accumulation of 0.49-m snow water equivalence (SWE), the 1994 snowmelt season began on 5 May and lasted 32 days until 6 June. In contrast, the 1995 maximum accumulation of 1.31-m SWE did not occur until 1 June, and the snowmelt season lasted 45 days until July 16. Thus, a nearly threefold larger snowpack ablated in only 41% more time in the later 1995 snowmelt season. In 1994, net radiation accounted for 75% of the energy available to melt snow, and sensible and latent heat fluxes accounted for the remaining 25%. During the 1995 snowmelt season the mean air temperature was warmer (+1.3 degree C) and the mean specific humidity was greater (+0.6 g kg super(-1)) than during the 1994 snowmelt season. As a result, in 1995, sensible and latent heat fluxes accounted for 54% of the energy for snowmelt and net radiation accounted for only 46%. Midday maximum snowmelt rates were approximately equal in 1994 and 1995; the overall more rapid 1995 melt rate was due to the frequent occurrence of nocturnal melting, which did not occur in 1994. The large differences between these two snowmelt seasons provide analogies for understanding regional variability of snowmelt processes and for understanding alpine snowmelt response to climate variability and change.

Numerical climate models suggest that changes of land-surface water balances are highly sensitive to changes of plant-available water-holding capacity of soil, which depend on plant rooting depth and density. Wide area changes in rooting characteristics may result from (1) plant and plant community response to greenhouse warming, to carbon-dioxide fertilization, and changes in water balance and (2) anthropogenic deforestation and desertification. Rooting characteristics plays a critical role in global climate change.

The copepod was found distributed throughout the study area with a strong onshore-offshore abundance gradient. After its annual low, C. hamatus was found to increase in abundance slowly along the coast and to expand offshore following the northward progression of spring conditions. The highest monthly mean abundance estimates of C. hamatus were found on Georges Bank during the month of July. Distribution begins to constrict inshore following peak abundance periods. Examination of environmental variables revealed that in general Centropages hamatus was prevalent when surface temperatures ranged from 12 to 17 degree C, when water-column chlorophyll levels were high, and where salinity was low on the shelf. The population in the Middle Atlantic Bight sub-area declines sharply as water temperatures rise in summer and does not begin to recover until temperatures decline in the fall. In contrast, populations in the more northern regions decrease slowly from peak abundance and do not increase from their annual low until water temperatures rise in early spring. The pelagic population that survives through low abundance periods is concentrated in shoal or inshore (or both) waters where temperature is low and phytoplankton biomass high. There was no evidence from survey data that predation by ctenophores, chaetognaths, or the copepod Centropages typicus has a major effect on C. hamatus abundance.

The methods included a growth curve, age-length keys, and a probabilistic method to classify a known total number of fish into ages from samples of the length frequency of the catch. In the first method, ages were estimated from sample lengths directly from the growth curve. The second method involved expanding the sample length frequency to age frequency by using age-length keys. The probabilistic method incorporated the cumulative frequency distributions of length at age, year-class strength, and estimates of prior survival to build age probability distributions from sampled lengths. The evaluation was based on the error in the assigned catch at age and on the resulting estimates of numbers at age and fishing mortality arising from sequential population analysis. The probabilistic method was the best of the three for the situation evaluated here, and application of the age-length key was better than that of the growth model. However, the probabilistic method requires knowledge of growth, the distributions of size at age, and recruitment that may not be known, or only poorly so. Age-length keys require no such ancillary information and may be more practical in most situations, but the probabilistic method is superior if the data requirements can be met.

Juveniles settled annually to spatially stable aggregations, occupying expanses of uniform sedimentary habitat. Habitat data were collected and used in a logistic regression model to predict correctly 68% of the juveniles' spatial variability. Premium habitat was identified as a sediment bottom, free of relief, and close to focused sources of drainage (reef platforms, embayments, and anthropogenic sources) in adjacent shallows. Surveys for juveniles elsewhere on insular slopes of the Hawaiian Archipelago indicated low juvenile abundance except at infrequent locations close to point sources of coastal drainage. Estimates of recruit production, based on densities of juveniles from other than premium habitat, were a small fraction of the recruits needed (calculated from catch) to account for the fishery's current landings of adult snappers. The 68-fold higher juvenile abundance at premium habitat can reconcile this difference, indicating that such infrequent high-quality habitat is an important (perhaps critical) fishery resource.

AN - 15694010; 3967088 AB - Twelve years of atmospheric CH sub(4) data from a globally distributed set of sampling sites ranging in latitude from 82 degree N to 90 degree S are analyzed to determine if a statistically significant trend in the peak-to-peak seasonal cycle amplitude exists. Two analysis methods are used. Agreement between amplitude trends determined by the two methods is reasonable. Trends in amplitude determined from sampling sites of similar latitude are not consistent, except in the high southern latitudes, so we focus on the latitude zone 30-90 degree S, where CH sub(4) destruction is the primary factor determining the seasonal cycle amplitude. In this high southern hemisphere latitude zone, the trend in seasonal cycle amplitude is not statistically different from zero. Statistical uncertainties in the peak-to-peak seasonal cycle amplitude suggest that the observations are consistent with the change in the amplitude expected due to the increasing burden of atmospheric CH sub(4), but not with an increase in the globally averaged OH concentration.

Associations among variations of cloudiness, precipitable water and relative humidity during the 1973-93 period over the U.S. as a whole and in the six regions were determined. Trends in the quantities as well as relations among seasonal variations have been examined. There was a general increase in precipitable water in each season and in each region and a suggestion of increases in relative humidity. These were not accompanied by a general increase in cloudiness that was significant. However, there were significant correlations between seasonal anomalies of cloudiness and both relative humidity and precipitable water.

Landings from commercial fishers in Broward County have been used to describe the structure and seasonal dynamics of the multispecies harvest. Cluster analysis showed significant seasonal changes in the species assemblages landed. Swordfish landings dominated the low-diversity harvest associated with certain fishing habitats and gear. No other species showed strong associations. These results reflect commercial fishing selectivity, gear used, and market values of various fish species. Seasonal changes in the harvest reveal species availability and the adaptability of fishers in switching to other target species. Such biases conceal natural fish community dynamics.

Beginning in 1991, more sea lions were observed entangled in fishing gear than in previous years. Numbers of entangled sea lions observed in 10 of 11 breeding colonies from 1991-95 in the central-northern part of the gulf were studied, and possible effects on the population as a whole are discussed. Estimates of entanglement frequency and types of fishing gear involved are presented. The percentage of young animals entangled was statistically higher than their proportion in the population. No links could be proven or disproven between the high juvenile mortality due to entanglement and any decrease in the overall population. Other data on entanglement rates, fishing gear involved, and the main time of entanglement are reported.

These differed from the climate for which it was developed and were intended to provide insights for the evolution of regulation criteria for extreme conditions. The climates, which were applied to thermodynamic models of the Great lakes and hydrological models of their catchments, provided 4 alternative scenarios of water supplies to the lake. These were then analysed with reference to the present Great lakes climate. Several key issues were revealed by the exercise. Historical water supplies were inadequate as the only basis for lake regulation plans. None of the regulation criteria could be met simultaneously and priorities needed to change under extreme conditions, with the possibility of altering the 1909 Boundary Waters Treaty. New regulation criteria had to address ecosystem health and socio-economic benefits and not be based on historical flow data. Better water supply forecasts and monitoring of hydrological conditions were necessary under the present climate and any future climatic conditions.

Sampling frequency during the study period ranged from weekly to semi-annually. The extent of sediment resuspension was indicted by the sediment trap mass and tracer profiles during the 6-month unstratified period, which were almost constant. Following the onset of stratification there was a marked decline in mass flux, with particle tracers removed from the epilimnion at a rate of 0.5-1 m per d. The persistence of a benthic nepheloid layer was indicated by exponential profiles of mass flux. Large changes in mass flux over periods of a few days were shown by high-frequency sampling with near-bottom sequencing traps.

Further studies of archived mussel sample material collected between 1986 and 1993 and originally analysed following nitric acid or nitric/perchloric acid digestion showed wide discrepancies with repeat analyses using nitric/hydrochloric acid digestion, which gave significantly higher values, one-tenth being as much as 100 per cent higher. Based on the revised figures, temporal trends in silver concentrations in mussels taken from the coastal regions of the U.S.A. were re-evaluated; there were significant decreases, mostly in the northeast, with time; this effect being attributed to a reduction in the silver concentration in effluents discharged to coastal waters between 1986 and 1993, probably due to improved recovery from photographic process wastewaters.

The NBSB provided long-term storage of documented and preserved specimens representing several types of environmental matrices. Selected specimens were periodically analysed for chlorinated hydrocarbons and trace elements. Although only 20 per cent of the 560 marine mammal specimens in the NBSB had been analysed, the database was valuable for evaluating analyte stability, sample degradation, and for comparisons with future analyses and results on samples collected for monitoring purposes by other laboratories. Much data are tabulated for seals, harbour porpoise, white-sided dolphin, beluga whale and bowhead whale. There are 38 references.

Concentrations of OC in bearded and ringed seals from the Alaska Arctic were relatively low, while those in harbour seals from Prince William sound were somewhat higher. In contrast, levels of PCB, DDT and chlordanes in northern fur seals from the Pribilof islands were, at mean values of 1343, 2711 and 792 ng per g wet weight, respectively, around an order of magnitude greater. The differences were most likely the result of feeding habits and migratory patterns rather than age or sex. Harbour seals stranded along the northwest U.S. mainland were most contaminated, a result consistent with greater levels of anthropogenic contaminants. There are 30 references.

Uptake kinetics and mortality were studied and fluoranthene concentrations in sediment and pore water were determined. At the highest fluoranthene concentrations, mean survival of H. azteca and Diporeia sp. were 74 and 14 per cent, respectively, after 30 d. Diporeia sp. accumulated high levels of fluoranthene (up to 2-4 umol per g wet weight) but H. azteca did not accumulate more than 1 umol per g wet weight. Apparent steady- state biota-sediment accumulation factors for sediment fluoranthene concentrations were higher for Diporeia than for H. azteca, with the exception of trace fluoranthene concentrations where the accumulation factors were higher for H. azteca than Diporeia.

Samples were acid digested for metal determinations by atomic absorption spectrophotometry. Tissues were extracted, extracts cleaned-up and chlorinated hydrocarbons (CHC) measured by high performance liquid chromatography and gas chromatography-mass spectrometry. The composition of lipids was ascertained by thin layer chromatography. Log-transformed data were examined by three-way analysis of variance. Anatomical location had no significant effect on concentrations of CHC but the strata of the blubber did so, that nearest the skin tending to be lower in concentration than blubber near the muscle despite similar lipid contents. No variations were observed within the liver. In general, the distribution of CHC among the organs depended on their lipid content, the exception being the brain which received some protection from the blood-brain barrier. The distribution of the elements was more variable, being influenced by low molecular weight problems.

Archived specimens included bivalves, marine sediments and fish tissues collected by the National Status and Trends, and the Exxon Valdez Oil Spill Damage Assessment programmes. Marine mammal tissues were obtained by the Marine Mammal Health and Stranding Response programme and the Alaska Marine Mammal Tissues Archival Project. In addition to supporting these programmes, the specimens provided data for investigations into circumpolar patterns of chlorinated hydrocarbon concentrations, genetic separation of marine animal stocks, baseline levels of trace elements in marine mammals and the potential risk to humans from contaminants in local subsistence foods.

The construction of the model was critically dependent on obtaining accurate data on age-specific survival and reproduction rates in various exposure conditions. For the present study a substantial amount of data was available from previous research on the effects of chemical contaminants on survival and reproduction during the past 15 years. Declines in the fecundity component of this model could substantially decrease the population growth rate if density dependence was weak or moderate. There are 75 references.

The effects of the PCB on hatch success and survival of larvae through the yolk resorption stage were examined. The rainbow trout eggs and larvae accumulated up to 570 ug PCB metabolite per g. It was not possible to determine uptake for the westslope cutthroat trout. The highest exposure concentration of the PCB metabolite significantly reduced the percentage of viable rainbow trout larvae. PCB metabolite concentrations of 45 and 95 mg per litre significantly reduced the percentage of viable cutthroat trout larvae. There were no significant differences between mean hatching success in any of the treatments.

Hepatic AHH activity was determined according to previously published methods using carbon-14 labelled benzo[apyrene as primary substrate. Stability of AHH activity was ascertained in whole liver and subcellular fractions. Log-transformed data were analysed by one-way analysis of variance. Whole liver could be stored for 24 months and microsomal suspensions for 5 months before significant changes took place in the parameters. Detailed protocols for sample collection, handling, storage and assay were developed so that valid trends in AHH activities could be discerned. These are described in detail and summarized in a diagram. JF - Chemosphere AU - Anulacion, B F AU - Bill, B D AU - Collier, T K AD - National Oceanic and Atmospheric Administration, Seattle, Wash.

However, in general, chemical contamination was decreasing and was less in rural sites near the Everglades than in more urban areas. High levels of mercury, arsenic and endosulfan were found in C. virginica in Florida bay. Contaminant levels in south Florida were low compared to those nationwide and as low as any found in uncontaminated sites in Central and South America.

Mean concentrations from 34 animals were 0.28, 0.051, 10.78, 17.8, 9.54 and 56.8 mg per kg wet weight for arsenic, cadmium, copper, mercury, selenium and zinc, respectively; chromium and lead were below 0.10 mg per kg wet weight. Mercury levels, with one exception, were below the 100-400 mg per kg wet weight range where hepatic damage could occur. Accumulation of arsenic was in descending order: adult female; adule male; juvenile female; juvenile male. Cadmium showed a similar trend. Further investigations were desirable to assess the effects of these elements on animals of different sex, ages and sizes.

The data were derived from estuarine samples collected annually for 6 years from sites with a wide range of contaminant levels. The winter flounder Pleuronectes americanus was sampled at 23 north Atlantic sites and the Atlantic croaker Micropogonias undulatus was sampled at 30 southeast Atlantic and Mexico gulf sites. Multivariate analysis was used to identify links between hepatic chemistry of metals and organic contaminants. Exposure of winter flounder to contaminants was 7 to 50 times higher than for Atlantic croaker. There was a link between organic exposure and depletion in hepatic concentrations of some metals, particularly zinc. There are 51 references.
