The data provide insight into the patterns of ecological succession, microbial nutrient demands, and the relative importance of free-living versus attached microbial populations. The most probable number (MPN) method was used to characterize the spatial distribution of six physiologic types: aerobes, denitrifiers, iron-reducers, heterotrophic fermenters, sulfate-reducers, and methanogens. Both free-living and attached numbers were determined over a broad cross-section of the aquifer extending horizontally from the source of the plume at a nonaqueous oil body to 66 m downgradient, and vertically from above the water table to the base of the plume below the water table. Point samples from widely spaced locations were combined with three closely spaced vertical profiles to create a map of physiologic zones for a cross-section of the plume. Although some estimates suggest that less than 1% of the subsurface microbial population can be grown in laboratory cultures, the MPN results presented here provide a comprehensive qualitative picture of the microbial ecology at the plume scale. Areas in the plume that are evolving from iron-reducing to methanogenic conditions are clearly delineated and generally occupy 25-50% of the plume thickness. Lower microbial numbers below the water table compared to the unsaturated zone suggest that nutrient limitations may be important in limiting growth in the saturated zone. Finally, the data indicate that an average of 15% of the total population is suspended.","language":"English","publisher":"Springer","doi":"10.1007/s002489900149","issn":"00953628","usgsCitation":"Bekins, B., Godsy, E., and Warren, E., 1999, Distribution of microbial physiologic types in an aquifer contaminated by crude oil: Microbial Ecology, v. 37, no. 4, p. 263-275, https://doi.org/10.1007/s002489900149.","productDescription":"13 p.","startPage":"263","endPage":"275","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":229214,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":206249,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s002489900149"}],"volume":"37","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a02e2e4b0c8380cd50245","contributors":{"authors":[{"text":"Bekins, B.A.","contributorId":98309,"corporation":false,"usgs":true,"family":"Bekins","given":"B.A.","email":"","affiliations":[],"preferred":false,"id":390459,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Godsy, E.M.","contributorId":56685,"corporation":false,"usgs":true,"family":"Godsy","given":"E.M.","email":"","affiliations":[],"preferred":false,"id":390458,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Warren, E.","contributorId":15360,"corporation":false,"usgs":true,"family":"Warren","given":"E.","email":"","affiliations":[],"preferred":false,"id":390457,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

These differences have been attributed to both variations in stream inputs and in situ lake processes (Priscu, 1995; Lizotte et al., 1996, Spigel and Priscu, 1996). This study examines the role of nitrifying bacteria in nitrogen transformations in these lakes. Applying two polymerase chain reaction (PCR) assays targeting the 16S rRNA genes of ammonia-oxidizing bacteria and the active site of the ammonia monooxygenase gene (amoA), the distribution of ammonia-oxidizers was examined in six Antarctic lakes: Lake Bonney, Lake Hoare, Lake Fryxell and Lake Joyce in the Taylor Valley, Lake Miers in the the Miers Valley and Lake Vanda in the Wright Valley. Using a two stage amplification procedure, ammonia-oxidizers from both the beta and gamma- subclasses of the Proteobacteria were detected and their relative abundances were determined in samples collected from all sites. Ammonia-oxidizers were detected in all lakes sampled. Members of the gamma subclass were only present in the saline lakes. In general, nitrifiers were most abundant at depths above the pycnocline and were usually associated with lower concentrations of NH4 and elevated concentrations of NO3 or NO2. The distribution of nitrifiers suggests that the primary N2O peak observed in most of the lakes was produced via nitrification. Preliminary data on the rate of nitrification (Priscu et al., 1996) support the occurrence of nitrification and the presence of nitrifiers at the depth intervals where nitrifiers were detected. In all lakes, except Lake Miers, the data indicate that nitrifying bacteria have an important role in the vertical distribution of nitrogen compounds in these systems.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Hydrobiologia","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1023/A:1003754830988","issn":"00188158","usgsCitation":"Voytek, M., Priscu, J., and Ward, B., 1999, The distribution and relative abundance of ammonia-oxidizing bacteria in lakes of the McMurdo Dry Valley, Antarctica: Hydrobiologia, v. 401, p. 113-130, https://doi.org/10.1023/A:1003754830988.","startPage":"113","endPage":"130","numberOfPages":"18","costCenters":[],"links":[{"id":229251,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":206261,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1023/A:1003754830988"}],"volume":"401","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505baacee4b08c986b322a14","contributors":{"authors":[{"text":"Voytek, M.A.","contributorId":44272,"corporation":false,"usgs":true,"family":"Voytek","given":"M.A.","email":"","affiliations":[],"preferred":false,"id":390461,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Priscu, J.C.","contributorId":66396,"corporation":false,"usgs":true,"family":"Priscu","given":"J.C.","email":"","affiliations":[],"preferred":false,"id":390462,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Ward, B.B.","contributorId":7023,"corporation":false,"usgs":true,"family":"Ward","given":"B.B.","email":"","affiliations":[],"preferred":false,"id":390460,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Information concerning the uptake and distribution of lead to maternal and fetal tissues during pregnancy is poorly documented. A study was designed using domestic swine and lead isotope enrichment methodology to focus on maternal absorption and distribution of lead into bone and soft tissues, including the fetal compartment, under varying conditions of oral lead exposure and during altered physiological states (pregnant vs unbred). Total lead levels and Pb207/Pb206 ratios in bone (femur and vertebra), blood, and soft tissues (liver, kidney, brain) were determined by ICP-MS. Lead in fetal tissues derived from maternal bone could be differentiated from that derived from exogenous dosing. Unbred swine absorbed much less lead than pregnant females receiving the same dose. The accuracy and precision of ICP-MS at the instrumental level and for the entire method (sample collection, digestion, and analysis) were evaluated for both Pb207/Pb206 ratios and total lead. Several changes were suggested in method design to improve both instrumental and total method precision.","language":"English","publisher":"Atomic Spectrosopy Press","doi":"10.46770/AS.1999.06.001","usgsCitation":"May, T.W., Wiedmeyer, R., Brown, L., and Casteel, S.W., 1999, A lead isotope distribution study in swine tissue using ICP-MS: Atomic Spectroscopy, v. 20, no. 6, p. 199-211, https://doi.org/10.46770/AS.1999.06.001.","productDescription":"13 p.","startPage":"199","endPage":"211","numberOfPages":"13","costCenters":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"links":[{"id":229824,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":413705,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://www.at-spectrosc.com/as/article/abstract/199906001?st=article_issue","linkFileType":{"id":5,"text":"html"}}],"volume":"20","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e435e4b0c8380cd464d8","contributors":{"authors":[{"text":"May, Thomas W. tmay@usgs.gov","contributorId":211484,"corporation":false,"usgs":false,"family":"May","given":"Thomas","email":"tmay@usgs.gov","middleInitial":"W.","affiliations":[{"id":38257,"text":"USGS-Columbia Environmental Research Center, Columbia, MO (Retired)","active":true,"usgs":false}],"preferred":false,"id":389315,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wiedmeyer, Ray H.","contributorId":20096,"corporation":false,"usgs":true,"family":"Wiedmeyer","given":"Ray H.","affiliations":[],"preferred":false,"id":389313,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Brown, L.

The rate and extent of the emission during application, predominantly as spray particle drift, depends primarily on the application method (equipment and technique), the formulation and environmental conditions, whereas the emission after application depends primarily on the properties of the pesticide, soils, crops and environmental conditions. The fraction of the dosage that misses the target area may be high in some cases and more experimental data on this loss term are needed for various application types and weather conditions. Such data are necessary to test spray drift models, and for further model development and verification as well. Following application, the emission of soil fumigants and soil incorporated pesticides into the air can be measured and computed with reasonable accuracy, but further model development is needed to improve the reliability of the model predictions. For soil surface applied pesticides reliable measurement methods are available, but there is not yet a reliable model. Further model development is required which must be verified by field experiments. Few data are available on pesticide volatilization from plants and more field experiments are also needed to study the fate processes on the plants.

Their eruption age, based on published and six new radiocarbon dates, is approximately AD 1445. The flows have distinctive paleomagnetic directions with steep inclinations (40??-50??) and easterly declinations (0??-10??E). The lava was transported ~40 km from the vent to the coast in long, large-diameter lava tubes; the longest tube (Kazumura Cave) reaches from near the summit to within several kilometers of the coast near Kaloli Point. The estimated volume of the 'Aila'au flow field is 5.2 ?? 0.8 km3, and the eruption that formed it probably lasted for approximately 50 years. Summit overflows from Kilauea may have been nearly continuous between approximately AD 1290 and 1470, during which time a series of shields formed at and around the summit. The 'Aila'au shield was either the youngest or the next to youngest in this series of shields. Site-mean paleomagnetic directions for lava flows underlying the 'Aila'au flows form only six groups. These older pahoehoe flows range in age from 2750 to <18,000 BP, and the region was inundated by lava flows only three times in the past 5000 years. The known intervals between eruptive events average ~1600 years and range from ~1250 years to >2200 years. Lava flows from most of these summit eruptions also reached the coast, but none appears as extensive as the 'Aila'au flow field. The chemistry of the melts erupted during each of these summit overflow events is remarkably similar, averaging approximately 6.3 wt.% MgO near the coast and 6.8 wt.% MgO near the summit. The present-day caldera probably formed more recently than the eruption that formed the 'Aila'au flows (estimated termination ca. AD 1470). The earliest explosive eruptions that formed the Keanakako'i Ash, which is stratigraphically above the 'Aila'au flows, cannot be older than this age.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Bulletin of Volcanology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1007/s004450050279","issn":"02588900","usgsCitation":"Clague, D., Hagstrum, J., Beeson, M., and Champion, D., 1999, Kilauea summit overflows: Their ages and distribution in the Puna District, Hawai'i: Bulletin of Volcanology, v. 61, no. 6, p. 363-381, https://doi.org/10.1007/s004450050279.","startPage":"363","endPage":"381","numberOfPages":"19","costCenters":[],"links":[{"id":206411,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s004450050279"},{"id":229667,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"61","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a4091e4b0c8380cd64e74","contributors":{"authors":[{"text":"Clague, D.A.","contributorId":36129,"corporation":false,"usgs":true,"family":"Clague","given":"D.A.","email":"","affiliations":[],"preferred":false,"id":389274,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hagstrum, J.T.","contributorId":75922,"corporation":false,"usgs":true,"family":"Hagstrum","given":"J.T.","email":"","affiliations":[],"preferred":false,"id":389276,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Beeson, M.H.","contributorId":83118,"corporation":false,"usgs":true,"family":"Beeson","given":"M.H.","email":"","affiliations":[],"preferred":false,"id":389277,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Champion, D.E.","contributorId":70402,"corporation":false,"usgs":true,"family":"Champion","given":"D.E.","email":"","affiliations":[],"preferred":false,"id":389275,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Seven diets were each fed to four replicate lots of 300 first-feeding fry cultured in 75 1 aluminum troughs for 8 weeks. Two basal diets were manufactured with approximately equal nutrient content, one using krill and squid meals and the other anchovy meal as the primary protein-containing ingredients. The meals used to manufacture the diets were separated into two fractions: lipid (ether-extractable); and protein/ash (non-ether-extractable) using a large soxhlet. The fractions were then recombined to create two additional diets; one containing anchovy protein/ash with krill/squid lipid, the other krill/squid protein/ash with fish lipid. A fifth diet recombined krill/squid protein/ash with krill/squid lipid to evaluate effects of the extraction process. Two additional treatments included a diet with a portion of the krill meal replaced by poultry by-product meal, and the basal anchovy meal diet supplemented with sodium, magnesium, and copper. Fish consuming diets containing anchovy meal as the primary protein source gained more weight (P < 0.05) than fish consuming krill/squid meal-based diets. Dorsal fin index (DFI, measured as mean dorsal fin height x 100/total fish length) was greater (P < 0.05) for fish consuming diets containing krill/squid meal protein/ash fraction (DFI = 9.9%-10.0%) than for fish consuming diets containing anchovy meal protein/ash fraction (DFI = 4.9%-5.3%), regardless of lipid source. Supplementation of the anchovy meal diet with sodium, magnesium, and copper improved (P < 0.05) DFI by approximately 20%, but not to the level supported by the krill/squid meal protein/ash fraction diets. The cost of the krill meal diet was reduced by inclusion of poultry by-product meal without affecting dorsal fin condition. These data indicate that the dietary agent contributing to dorsal fin erosion in rainbow trout is not present in the ether-extractable fraction of the diet, but rather in the protein or mineral fraction.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Aquaculture","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/S0044-8486(99)00188-X","issn":"00448486","usgsCitation":"Barrows, F., and Lellis, W., 1999, The effect of dietary protein and lipid source on dorsal fin erosion in rainbow trout, Oncorhynchus mykiss: Aquaculture, v. 180, no. 1-2, p. 167-175, https://doi.org/10.1016/S0044-8486(99)00188-X.","startPage":"167","endPage":"175","numberOfPages":"9","costCenters":[],"links":[{"id":206564,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/S0044-8486(99)00188-X"},{"id":230223,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"180","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bab20e4b08c986b322c40","contributors":{"authors":[{"text":"Barrows, F.T.","contributorId":94998,"corporation":false,"usgs":true,"family":"Barrows","given":"F.T.","email":"","affiliations":[],"preferred":false,"id":389264,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lellis, W.A.","contributorId":67441,"corporation":false,"usgs":true,"family":"Lellis","given":"W.A.","email":"","affiliations":[],"preferred":false,"id":389263,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Fertilizer, biological fixation, atmospheric deposition, and animal feed were the N sources, and crop harvests, animal product exports, volatilization from fertilizer and manure, and denitrification were the N sinks in the model. Excess N, calculated as the difference between the sources and sinks, was assumed to leach to ground water as NO3/-. The budget was developed using ground water data collected throughout the 212-km2 study area. Denitrification was estimated by adjusting its value so the predicted and measured concentrations of NO3/- in ground water agreed. Although biological fixation was the largest single N source, most was removed when crops were harvested, indicating that inorganic fertilizer was the primary source of N reaching the water table. It was estimated that denitrification removed almost half of the excess NO3/- that leached below the root zone. Even after accounting for denitrification losses, however, it was concluded that the ground water system was receiving approximately three times as much N as would be expected under background conditions.","language":"English","publisher":"Wiley","doi":"10.2134/jeq1999.00472425002800060043x","issn":"00472425","usgsCitation":"Puckett, L., Cowdery, T., Lorenz, D., and Stoner, J., 1999, Estimation of nitrate contamination of an agro-ecosystem outwash aquifer using a nitrogen mass-balance budget: Journal of Environmental Quality, v. 28, no. 6, p. 2015-2025, https://doi.org/10.2134/jeq1999.00472425002800060043x.","productDescription":"11 p.","startPage":"2015","endPage":"2025","numberOfPages":"11","costCenters":[],"links":[{"id":479450,"rank":2,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.567.6377","text":"External Repository"},{"id":229861,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"28","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0b9be4b0c8380cd527c9","contributors":{"authors":[{"text":"Puckett, L.J.","contributorId":27503,"corporation":false,"usgs":true,"family":"Puckett","given":"L.J.","email":"","affiliations":[],"preferred":false,"id":389193,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Cowdery, T.K.","contributorId":92658,"corporation":false,"usgs":true,"family":"Cowdery","given":"T.K.","affiliations":[],"preferred":false,"id":389195,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Lorenz, D.

Fish mortalities in instream cages located in the mixing zone, below the mixing zone, and upstream in both tributaries were compared to determine relative toxicity at each site. In all tests and for both species, significantly higher mortality was observed in the mixing zone than at any other location, including the acid stream, which had lower pH (2.9-4.3). The mixing zone was defined chemically by rapid precipitation of dissolved aluminum and iron, which arrived from the low-pH stream, and by the presence of white precipitates, which were attached to the substratum and which extended below the confluence. Possible seasonal changes in mixing zone toxicity were investigated by conducting field tests with bluegill in June, July, and August 1996 and in January 1997 and by conducting field tests with largemouth bass in April and May 1997. Toxicity was not significantly different at the extremes of temperature, pH, and metal concentration that occurred in June and July, as compared with January. Toxicity was significantly lower in August; however, elevated stream discharge during the August test may have disturbed mixing zone characteristics. High toxicity in AMD mixing zones may lower the survival of fishes in streams, reduce available habitat, and impede movements of migratory fish.","language":"English","publisher":"Taylor & Francis","doi":"10.1577/1548-8659(1999)128<0919:ATOAAM>2.0.CO;2","issn":"00028487","usgsCitation":"Henry, T., Irwin, E., Grizzle, J., Wildhaber, M., and Brumbaugh, W.G., 1999, Acute toxicity of an acid mine drainage mixing zone to juvenile bluegill and largemouth bass: Transactions of the American Fisheries Society, v. 128, no. 5, p. 919-928, https://doi.org/10.1577/1548-8659(1999)128<0919:ATOAAM>2.0.CO;2.","productDescription":"10 p.","startPage":"919","endPage":"928","numberOfPages":"10","costCenters":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"links":[{"id":230065,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"128","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e6dae4b0c8380cd47690","contributors":{"authors":[{"text":"Henry, T.B.","contributorId":16183,"corporation":false,"usgs":true,"family":"Henry","given":"T.B.","email":"","affiliations":[],"preferred":false,"id":389375,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Irwin, E.R.","contributorId":90269,"corporation":false,"usgs":true,"family":"Irwin","given":"E.R.","email":"","affiliations":[],"preferred":false,"id":389378,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Grizzle, J.M.","contributorId":57016,"corporation":false,"usgs":true,"family":"Grizzle","given":"J.M.","email":"","affiliations":[],"preferred":false,"id":389376,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Wildhaber, M.

We measured sediment and water variables in 32 pairs of wetlands with and without a current outbreak of avian botulism. Wetlands with botulism outbreaks had greater percent organic matter (POM) in the sediment (P = 0.088) and lower redox potential in the water (P = 0.096) than paired control wetlands. We also found that pH, redox potential, temperature, and salinity measured just above the sediment-water interface were associated (P ≤ 0.05) with the risk of botulism outbreaks in wetlands, but relations were complex, involving nonlinear and multivariate associations. Regression models indicated that the risk of botulism outbreaks increased when water pH was between 7.5 and 9.0, redox potential was negative, and water temperature was >20°C. Risk declined when redox potential increased (>100), water temperature decreased (10-15°C), pH was <7.5 or >9.0, or salinity was low (<2.0 ppt). Our predictive models could allow managers to assess potential effects of wetland management practices on the risk of botulism outbreaks and to develop and evaluate alternative management strategies to reduce losses from avian botulism.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Wildlife Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","doi":"10.2307/3802842","issn":"0022541X","usgsCitation":"Rocke, T.E., and Samuel, M.D., 1999, Water and sediment characteristics associated with avian botulism outbreaks in wetlands: Journal of Wildlife Management, v. 63, no. 4, p. 1249-1260, https://doi.org/10.2307/3802842.","productDescription":"12 p.","startPage":"1249","endPage":"1260","numberOfPages":"12","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":456,"text":"National Wildlife Health Center","active":true,"usgs":true}],"links":[{"id":230101,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":288514,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2307/3802842"}],"country":"United States","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -124.98046874999999,\n              25.64152637306577\n            ],\n            [\n              -124.98046874999999,\n              49.32512199104001\n            ],\n            [\n              -86.748046875,\n              49.32512199104001\n            ],\n            [\n              -86.748046875,\n              25.64152637306577\n            ],\n            [\n              -124.98046874999999,\n              25.64152637306577\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"63","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bc7a4e4b08c986b32c565","contributors":{"authors":[{"text":"Rocke, Tonie E. 0000-0003-3933-1563 trocke@usgs.gov","orcid":"https://orcid.org/0000-0003-3933-1563","contributorId":2665,"corporation":false,"usgs":true,"family":"Rocke","given":"Tonie","email":"trocke@usgs.gov","middleInitial":"E.","affiliations":[{"id":456,"text":"National Wildlife Health Center","active":true,"usgs":true}],"preferred":true,"id":389246,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Samuel, Michael D. msamuel@usgs.gov","contributorId":1419,"corporation":false,"usgs":true,"family":"Samuel","given":"Michael","email":"msamuel@usgs.gov","middleInitial":"D.","affiliations":[{"id":199,"text":"Coop Res Unit Leetown","active":true,"usgs":true}],"preferred":true,"id":389245,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Fish were sampled with beach seines (n=413 sets) and midwater trawls (n=39 sets). We found that lower Cook Inlet supported a diverse nearshore fish community of at least 52 species. Fifty of these species were caught in Kachemak Bay, 24 at Chisik Island, and 12 at the Barren Islands. Pacific sand lance dominated Barren Islands and Kachemak Bay nearshore habitats, comprising 99% and 71% of total individuals, respectively. The nearshore Chisik Island fish community was not dominated by any one species; instead it exhibited higher diversity. These spatial differences appeared linked to local oceanographic regimes and sediment influx. Analysis of historical data revealed that the nearshore Kachemak Bay fish community changed significantly between 1976 and 1996, showing increased diversity and abundance in several taxa, notably gadids, salmonids, pleuronectids, and sculpins. Decadal differences appeared to be related to large-scale climate changes in the North Pacific. Catches of most taxa peaked in May-August, and were low during other months of the year. Several species were present for only part of the summer. Species composition of seine catches differed significantly between consecutive high and low tides, but not between consecutive sets or years. Midwater trawls took 26 species, 14 of which were present in Kachemak Bay, 19 near Chisik Island, and 7 at the Barren Islands. Community structures in shelf and nearshore waters were similar: diversity was high and abundance low at Chisik Island, whereas a few abundant species dominated at both Kachemak Bay and the Barren Islands. In addition, the low fish abundance near Chisik Island appeared to be related to declining seabird numbers at this colony.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Fishery Bulletin","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"00900656","usgsCitation":"Robards, M.D., Piatt, J.F., Kettle, A.B., and Abookire, A.A., 1999, Temporal and geographic variation in fish communities of lower Cook Inlet, Alaska: Fishery Bulletin, v. 97, no. 4, p. 962-977.","startPage":"962","endPage":"977","numberOfPages":"16","costCenters":[],"links":[{"id":229944,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":336338,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://fishbull.noaa.gov/974/974toc.htm","text":"Fishery Bulletin: Volume 97, Issue 4"}],"volume":"97","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505ba4e9e4b08c986b320675","contributors":{"authors":[{"text":"Robards, Martin D.","contributorId":40148,"corporation":false,"usgs":false,"family":"Robards","given":"Martin","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":389204,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Piatt, John F. 0000-0002-4417-5748 jpiatt@usgs.gov","orcid":"https://orcid.org/0000-0002-4417-5748","contributorId":3025,"corporation":false,"usgs":true,"family":"Piatt","given":"John","email":"jpiatt@usgs.gov","middleInitial":"F.","affiliations":[{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true}],"preferred":true,"id":389205,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kettle, Arthur B.","contributorId":98064,"corporation":false,"usgs":false,"family":"Kettle","given":"Arthur","email":"","middleInitial":"B.","affiliations":[],"preferred":false,"id":389206,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Abookire, Alisa A.","contributorId":107224,"corporation":false,"usgs":true,"family":"Abookire","given":"Alisa","email":"","middleInitial":"A.","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":false,"id":389207,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

High-resolution seismic data were collected from 30 lakes of north-central Florida. In each case study, lake structure and geomorphology were controlled by solution and/or mechanical processes. Processes that control lake development are twofold: (1) karstification or dissolution of the underlying limestone, and (2) the collapse, subsidence, or slumping of overburden to form sinkholes. Initial lake formation is directly related to the karst topography of the underlying host limestone. Case studies have shown that lakes can be divided by geomorphic types into progressive developmental phases: (1) active subsidence or collapse phase (young); (2) transitional phase (middle age); (3) baselevel phase (mature); and (4) polje (drowned prairie) – broad flat-bottom that have one or all phases of sinkhole. Using these criteria, Florida lakes can be classified by size, fill, subsurface features, and geomorphology.</span></p>","language":"English","publisher":"Springer Link","doi":"10.1007/s002540050428","usgsCitation":"Kindinger, J., Davis, J.B., and Flocks, J.G., 1999, Geology and evolution of lakes in north-central Florida: Environmental Geology, v. 38, no. 4, p. 301-321, https://doi.org/10.1007/s002540050428.","productDescription":"21 p.","startPage":"301","endPage":"321","numberOfPages":"21","costCenters":[],"links":[{"id":230024,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Florida","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -82.5,\n              30.1\n            ],\n            [\n              -82.5,\n              28.5\n            ],\n            [\n              -81,\n              28.5\n            ],\n            [\n              -81,\n              30.1\n            ],\n            [\n              -82.5,\n              30.1\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"38","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a22cce4b0c8380cd57346","contributors":{"authors":[{"text":"Kindinger, J.

Pore-fluid pressures nearly sufficient to cause liquefaction were developed and maintained during flow mobilization and acceleration, persisted in debris-flow interiors during flow deceleration and deposition, and dissipated significantly only during postdepositional sediment consolidation. In contrast, leading edges of debris flows exhibited little or no positive pore-fluid pressure. Deposition therefore resulted from grain-contact friction and bed friction concentrated at flow margins. This finding contradicts models that invoke widespread decay of excess pore-fluid pressure, uniform viscoplastic yield strength, or pervasive grain-collision stresses to explain debris-flow deposition. Furthermore, the finding demonstrates that deposit thickness cannot be used to infer the strength of flowing debris.</p></div>","language":"English","publisher":"Geological Society of America","doi":"10.1130/0016-7606(1999)111<1424:DFDEOP>2.3.CO;2","usgsCitation":"Major, J., and Iverson, R., 1999, Debris-flow deposition: Effects of pore-fluid pressure and friction concentrated at flow margins: Geological Society of America Bulletin, v. 111, no. 10, p. 1424-1434, https://doi.org/10.1130/0016-7606(1999)111<1424:DFDEOP>2.3.CO;2.","productDescription":"11 p.","startPage":"1424","endPage":"1434","numberOfPages":"11","costCenters":[{"id":157,"text":"Cascades Volcano Observatory","active":false,"usgs":true}],"links":[{"id":229905,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"111","issue":"10","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059fdf6e4b0c8380cd4ea30","contributors":{"authors":[{"text":"Major, J.

One potential virulence factor is p57 (also designated MSA for major soluble antigen), an abundant 57 kDa soluble protein that is predominately localized on the bacterial cell surface with significant levels released into the extracellular milieu. Previous studies of an attenuated strain, MT 239, indicated that it differs from virulent strains in the amount of surface-associated p57. In this report, we show overall expression of p57 in R. salmoninarum MT 239 is considerably reduced as compared to a virulent strain, ATCC 33209. The amount of cell-associated p57 is decreased while the level of p57 in the culture supernatant is nearly equivalent between the strains. To determine if lowered amount of cell-associated p57 was due to a sequence defect in p57, a genetic comparison was performed. Two copies of the gene encoding p57 (msa1 and msa2) were found in 33209 and MT 239, as well as in several other virulent isolates. Both copies from 33209 and MT 239 were cloned and sequenced and found to be identical to each other, and identical between the 2 strains. A comparison of msa1 and msa2 within each strain showed that their sequences diverge 40 base pairs 5, to the open reading frame, while sequences 3' to the open reading frame are essentially identical for at least 225 base pairs. Northern blot analysis showed no difference in steady state levels of rosa mRNA between the 2 strains. These data suggest that while cell-surface localization of p57 may be important for R. salmoninarum virulence, the differences in localization, and total p57 expression between 33209 anti MT 239 are not due to differences in rosa sequence or differences in steady state transcript levels.","language":"English","publisher":"Inter-Research","doi":"10.3354/dao038115","issn":"01775103","usgsCitation":"O'Farrell, C., and Strom, M., 1999, Differential expression of the virulence-associated protein p57 and characterization of its duplicated gene rosa in virulent and attenuated strains of Renibacterium salmoninarum: Diseases of Aquatic Organisms, v. 38, no. 2, p. 115-123, https://doi.org/10.3354/dao038115.","productDescription":"9 p.","startPage":"115","endPage":"123","numberOfPages":"9","costCenters":[],"links":[{"id":479582,"rank":2,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.3354/dao038115","text":"Publisher Index Page"},{"id":229985,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"38","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a00fae4b0c8380cd4fa12","contributors":{"authors":[{"text":"O'Farrell, C.
