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.

N1 - Last updated - 2014-05-07 ER - TY - JOUR T1 - The Influence of Spear Fishing on Species Composition and Size of Groupers on Patch Reefs in the Upper Florida Keys AN - 14496238; 10551355 AB - The influence of spear fishing on the size and species composition of groupers in the upper Florida Keys were compared in areas open and closed to spear fishing. 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.
