Presented here is a historically complete listing starting with the values in F. W. Clarke's 1882 recalculation, followed by the recommended values in the annual reports of the American Chemical Society's Atomic Weights Commission. From 1903, an International Commission published such reports and its values (scaled to an atomic weight of 16 for oxygen) are here used in preference to those of national committees of Britain, Germany, Spain, Switzerland, and the U.S.A. We have, however, made scaling adjustments from Ar(16O) to Ar(12C) where not negligible. From 1920, this International Commission constituted itself under the International Union of Pure and Applied Chemistry (IUPAC). Since then, IUPAC has published reports (mostly biennially) listing the recommended atomic weights, which are reproduced here. Since 1979, these values have been called the \"standard atomic weights\" and, since 1969, all values have been published, with their estimated uncertainties. Few of the earlier values were published with uncertainties. Nevertheless, we assessed such uncertainties on the basis of our understanding of the likely contemporary judgement of the values' reliability. While neglecting remaining uncertainties of 1997 values, we derive \"differences\" and a retrospective index of reliability of atomic-weight values in relation to assessments of uncertainties at the time of their publication. A striking improvement in reliability appears to have been achieved since the commissions have imposed upon themselves the rule of recording estimated uncertainties from all recognized sources of error.","language":"English","publisher":"De Gruyter Brill","doi":"10.1351/pac199870010237","issn":"00334545","usgsCitation":"Coplen, T., and Peiser, H., 1998, History of the recommended atomic-weight values from 1882 to 1997: A comparision of differences from current values to the estimated uncertainties of earlier values: Pure and Applied Chemistry, v. 70, no. 1, p. 237-257, https://doi.org/10.1351/pac199870010237.","productDescription":"21 p.","startPage":"237","endPage":"257","numberOfPages":"21","costCenters":[],"links":[{"id":492504,"rank":2,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1351/pac199870010237","text":"Publisher Index Page"},{"id":230158,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"70","issue":"1","noUsgsAuthors":false,"publicationDate":"2009-01-01","publicationStatus":"PW","scienceBaseUri":"505a31cae4b0c8380cd5e22d","contributors":{"authors":[{"text":"Coplen, T.B.","contributorId":34147,"corporation":false,"usgs":true,"family":"Coplen","given":"T.B.","affiliations":[],"preferred":false,"id":387916,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Peiser, H.S.","contributorId":64303,"corporation":false,"usgs":true,"family":"Peiser","given":"H.S.","email":"","affiliations":[],"preferred":false,"id":387917,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Understanding controls on variability in water levels, water volume, and salinity in these wetlands sets the stage for understanding controls on biological communities utilizing these wetlands.

These waters are immediately downstream from Finfeather Lake which was directly contaminated during 53 years of industrial production of arsenic (As)-based cotton defoliants. The tadpoles contained elevated levels of arsenic, chromium (Cr) and zinc (Zn). As far as it is known, the mean concentrations of As (6.87 p.p.m. wet weight) and Cr (6.91 p.p.m. wet weight) in cricket frog (Acris crepitans) tadpoles were the highest ever reported in tadpoles. The Zn in the tadpoles exceeded the levels found in sediments by six to 11 times. The concentrations of As, Cr and Zn in Finfeather Lake in 1994 may have been toxic because tadpoles could not be found there. Ranid tadpoles and a newly transformed ranid frog found dead in Lateral Pond and Municipal Lake in 1994 may indicate that the elements reached toxic levels in some individual amphibians. The concentrations of As, Cr and Zn found in the tadpoles in this study might be toxic to predators. Mortality of turtles showing symptoms linked to chronic exposure to As was reported in Finfeather Lake in 1973. Turtles were not reported in Finfeather Lake again until 1996. Observations at Municipal Lake in 1994-1996 showed abundant tadpoles and turtles but no snakes, which also have not been seen at Finfeather Lake. This absence of snakes may indicate that their sensitivity or exposure to the existing contaminants is greater than that of frogs and turtles.","language":"English","publisher":"Elsevier","doi":"10.1023/A:1008819132474","issn":"09639292","usgsCitation":"Clark, D.R., Cantu, R., Cowman, D., and Maxson, D., 1998, Uptake of arsenic and metals by tadpoles at an historically contaminated Texas site: Ecotoxicology, v. 7, no. 2, p. 61-67, https://doi.org/10.1023/A:1008819132474.","productDescription":"7 p.","startPage":"61","endPage":"67","costCenters":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"links":[{"id":229923,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"7","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bbd74e4b08c986b329037","contributors":{"authors":[{"text":"Clark, D.

In this study, fractions and pool sizes of N were determined in the forest floor of red spruce stands at four sites in the northeastern U.S. to evaluate the effect of increased N inputs on forest floor N. Two of the stands received 100 kg N ha-1 yr-1 for three years, one stand received 34 kg N ha-1 yr-1 for six years, and the remaining stand received only ambient N inputs. No differences in total N content or N fractions were measured in samples of the Oie and Oa horizons between treated and control plots in the three sites that received N amendments. The predominant N fraction in these samples was amino acid N (31-45 % of total N), followed by hydrolyzable unidentified N (16-31% of total N), acid- soluble N (18-22 % of total N), and NH4/+-N (9-13 % of total N). Rates of atmospheric deposition varied greatly among the four stands. Ammonium N and amino acid N concentrations in the Oie horizon were positively related to wet N deposition, with respective r2 values of 0.92 and 0.94 (n = 4, p < 0.05). These relationships were somewhat stronger than that observed between atmospheric wet N deposition and total N content of the forest floor, suggesting that these pools retain atmospherically deposited N. The NH4/+- N pool may represent atmospherically deposited N that is incorporated into organic matter, whereas the amino acid N pool could result from microbial immobilization of atmospheric N inputs. The response of forest floor N pools to applications of N may be masked, possibly by the large soil N pool, which has been increased by the long-term input of N from atmospheric deposition, thereby overwhelming the short-term treatments.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Water, Air, and Soil Pollution","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Kluwer Academic Publishers","publisherLocation":"Dordrecht, Netherlands","doi":"10.1023/A:1005012400047","issn":"00496979","usgsCitation":"David, M., Cupples, A., Lawrence, G., Shi, G., Vogt, K., and Wargo, P., 1998, Effect of chronic nitrogen additions on soil nitrogen fractions in red spruce stands: Water, Air, & Soil Pollution, v. 105, no. 1-2, p. 183-192, https://doi.org/10.1023/A:1005012400047.","startPage":"183","endPage":"192","numberOfPages":"10","costCenters":[],"links":[{"id":230038,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":206507,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1023/A:1005012400047"}],"volume":"105","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a05c9e4b0c8380cd50f6b","contributors":{"authors":[{"text":"David, M.B.","contributorId":20089,"corporation":false,"usgs":true,"family":"David","given":"M.B.","email":"","affiliations":[],"preferred":false,"id":387755,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Cupples, A.M.","contributorId":49550,"corporation":false,"usgs":true,"family":"Cupples","given":"A.M.","email":"","affiliations":[],"preferred":false,"id":387757,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Lawrence, G.B. 0000-0002-8035-2350","orcid":"https://orcid.org/0000-0002-8035-2350","contributorId":76347,"corporation":false,"usgs":true,"family":"Lawrence","given":"G.B.","affiliations":[],"preferred":false,"id":387759,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Shi, G.","contributorId":28401,"corporation":false,"usgs":true,"family":"Shi","given":"G.","email":"","affiliations":[],"preferred":false,"id":387756,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Vogt, K.","contributorId":58043,"corporation":false,"usgs":true,"family":"Vogt","given":"K.","email":"","affiliations":[],"preferred":false,"id":387758,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Wargo, P.M.","contributorId":84943,"corporation":false,"usgs":true,"family":"Wargo","given":"P.M.","email":"","affiliations":[],"preferred":false,"id":387760,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Plastic mesh leaf retainers with approximately 10 g of leaves from five tree species were deployed at five sites (two upstream of the spill and three downstream) immediately after the spill and one year later. Four macroinvertebrate species dominating the community at upstream sites were virtually eliminated below the spill, including the stonefly Isoperla bilineata, the caddisfly Potamyia flava, the midge Thienemanniella xena, and blackfly larvae (Simulium sp.). Density of collector and shredder functional groups, and number of shredder taxa differed between upstream sites and the two furthest downstream sites during the 1990 sample period (Kruskal-Wallis w/Bonferroni paired comparisons, experiment wise error rate = 0.05). With one exception, no differences between sites were detected in the 1991-1992 sample period, indicating that the benthic community had at least partially recovered from the oil spill after one year. The odds of obtaining a sample with a small abundance of shredders (abundance < median) in 1990 was significantly greater downstream of the spill than upstream, and the odds of obtaining a sample with a small abundance of shredders at downstream sites was greater in 1990 than in 1991-1992. A similar pattern was observed in abundance and taxa richness of the collector functional group. No significant differences between the two sampling periods were detected at upstream sites. Observed effects appeared to be associated with oil sorption and substrate coating, creating conditions unsuitable for successful colonization.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Pollution","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/S0269-7491(97)00160-7","issn":"02697491","usgsCitation":"Poulton, B., Callahan, E., Hurtubise, R., and Mueller, B., 1998, Effects of an oil spill on leafpack-inhabiting macroinvertebrates in the Chariton river, Missouri: Environmental Pollution, v. 99, no. 1, p. 115-122, https://doi.org/10.1016/S0269-7491(97)00160-7.","startPage":"115","endPage":"122","numberOfPages":"8","costCenters":[],"links":[{"id":230037,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":206506,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/S0269-7491(97)00160-7"}],"volume":"99","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a068be4b0c8380cd512cd","contributors":{"authors":[{"text":"Poulton, B.C.","contributorId":22930,"corporation":false,"usgs":true,"family":"Poulton","given":"B.C.","email":"","affiliations":[],"preferred":false,"id":387751,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Callahan, E.V.","contributorId":74527,"corporation":false,"usgs":true,"family":"Callahan","given":"E.V.","email":"","affiliations":[],"preferred":false,"id":387754,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hurtubise, R.D.","contributorId":61592,"corporation":false,"usgs":true,"family":"Hurtubise","given":"R.D.","email":"","affiliations":[],"preferred":false,"id":387753,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Mueller, B.G.","contributorId":41618,"corporation":false,"usgs":true,"family":"Mueller","given":"B.G.","email":"","affiliations":[],"preferred":false,"id":387752,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

These correlations suggest that area surveys of properties like sand content may be sufficient to estimate ??C.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Waterway, Port, Coastal and Ocean Engineering","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1061/(ASCE)0733-950X(1998)124:1(40)","issn":"0733950X","usgsCitation":"Ravens, T., Madsen, O., Signell, R.P., Adams, E., and Gschwend, P., 1998, Hydrodynamic forcing and sediment character in Boston Harbor: Journal of Waterway, Port, Coastal and Ocean Engineering, v. 124, no. 1, p. 40-42, https://doi.org/10.1061/(ASCE)0733-950X(1998)124:1(40).","productDescription":"3 p.","startPage":"40","endPage":"42","costCenters":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":229725,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Massachussetts","otherGeospatial":"Boston Harbor","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -71.2188720703125,\n              42.134894984239224\n            ],\n            [\n              -70.54595947265625,\n              42.134894984239224\n            ],\n            [\n              -70.54595947265625,\n              42.551056983385934\n            ],\n            [\n              -71.2188720703125,\n              42.551056983385934\n            ],\n            [\n              -71.2188720703125,\n              42.134894984239224\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"124","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a333be4b0c8380cd5ee3f","contributors":{"authors":[{"text":"Ravens, T.M.","contributorId":94813,"corporation":false,"usgs":true,"family":"Ravens","given":"T.M.","email":"","affiliations":[],"preferred":false,"id":388131,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Madsen, O.S.","contributorId":61593,"corporation":false,"usgs":true,"family":"Madsen","given":"O.S.","email":"","affiliations":[],"preferred":false,"id":388129,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Signell, R.

A simplified basic conceptual model is adopted, incorporating two horizontal layers of porous medium which come into contact at a specific location within the model domain. The top layer is saturated with freshwater, and the bottom layer is saturated with saltwater. The paper considers various stages of approximation which can be useful for simplified simulation of the build-up of the transition zone (TZ) between the freshwater and the saltwater. The hierarchy of approximate approaches leads to the development of the top specified boundary layer (TSBL) method, which is the major tool used in this study for initial characterization of the development of the TZ. It is shown that the thickness of the TZ is mainly determined by the characteristic dispersivity. The build-up of the TZ is completed after a time period equal to the time needed to advect a fluid particle along the whole extent of the TZ. Potential applications and the effects of natural recharge and pumpage on salinity transport in the domain are discussed and evaluated in the context of demonstrating the practicality of the TSBL approach.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Contaminant Hydrology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/S0169-7722(98)00056-4","issn":"01697722","usgsCitation":"Rubin, H., and Buddemeier, R., 1998, Application of the top specified boundary layer (TSBL) approximation to initial characterization of an inland aquifer mineralization 1.

We observed both geographic and temporal variation in diet; gulls consumed proportionately more terrestrial prey after peak hatch in late June, and gulls near the coast consumed proportionately more marine prey than gulls at two inland areas. Goslings occurred in > 60% of all samples from these inland areas. We compared these data to those from a previous study in western Alaska and found no marked differences. Evidence for similar patterns of geographic and temporal variation in diet was found using measurements of stable-carbon and nitrogen isotopes in gull and prey tissues. Stable isotope analysis further revealed that adult gulls consumed proportionately more marine prey (saffron cod, Eleginus gracilis) than they fed to their young. Using isotopic models, we estimated that 7-22% and 10-23% of the diet of adult and juvenile Glaucous Gulls, respectively, was comprised of terrestrial species. In addition to significant age-related variation, dietary estimates varied among geographic areas and between pre- and post-hatch periods. Overall, our isotopic estimates of the contribution of terrestrial prey to the diet of Glaucous Gulls was less than what may be inferred from conventional methods of diet analysis. Our study emphasizes the benefit of combining stable-isotope and conventional analyses to infer temporal and geographic changes in diet of wild birds and other organisms.","language":"English","publisher":"Oxford Academic","doi":"10.2307/1369903","issn":"00105422","usgsCitation":"Schmutz, J.A., and Hobson, K., 1998, Geographic, temporal, and age-specific variation in diets of Glaucous Gulls in western Alaska: Condor, v. 100, no. 1, p. 119-130, https://doi.org/10.2307/1369903.","productDescription":"12 p.","startPage":"119","endPage":"130","numberOfPages":"12","costCenters":[],"links":[{"id":503079,"rank":2,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://digitalcommons.usf.edu/condor/vol100/iss1/13","text":"External Repository"},{"id":229726,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"100","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a178fe4b0c8380cd55544","contributors":{"authors":[{"text":"Schmutz, Joel A. 0000-0002-6516-0836 jschmutz@usgs.gov","orcid":"https://orcid.org/0000-0002-6516-0836","contributorId":1805,"corporation":false,"usgs":true,"family":"Schmutz","given":"Joel","email":"jschmutz@usgs.gov","middleInitial":"A.","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true}],"preferred":true,"id":388133,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hobson, K.A.","contributorId":23248,"corporation":false,"usgs":true,"family":"Hobson","given":"K.A.","email":"","affiliations":[],"preferred":false,"id":388134,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The objective is to minimize the cost of water supply subject to: water demand constraints, hydraulic head constraints to control seawater intrusion, and water capacity constraints. The decision variables are montly water deliveries from surface water and groundwater. The state variables are hydraulic heads. The drought of 1947-51 is the city's worst drought on record, and simulated surface-water supplies for this period were used as a basis for testing optimal management of current water resources under drought conditions. The simulation-optimization model was applied using three reservoir operation rules. In addition, the model's sensitivity to demand, carry over [the storage of water in one year for use in the later year(s)], head constraints, and capacity constraints was tested.","language":"English","publisher":"ASCE","doi":"10.1061/(ASCE)0733-9496(1998)124:5(252)","issn":"07339496","usgsCitation":"Nishikawa, T., 1998, Water-resources optimization model for Santa Barbara, California: Journal of Water Resources Planning and Management, v. 124, no. 5, p. 252-263, https://doi.org/10.1061/(ASCE)0733-9496(1998)124:5(252).","productDescription":"12 p.","startPage":"252","endPage":"263","numberOfPages":"12","costCenters":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"links":[{"id":229678,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":206418,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1061/(ASCE)0733-9496(1998)124:5(252)"}],"volume":"124","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bcedfe4b08c986b32e5e9","contributors":{"authors":[{"text":"Nishikawa, Tracy 0000-0002-7348-3838 tnish@usgs.gov","orcid":"https://orcid.org/0000-0002-7348-3838","contributorId":1515,"corporation":false,"usgs":true,"family":"Nishikawa","given":"Tracy","email":"tnish@usgs.gov","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":true,"id":387671,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Blueback herring most likely gained entry to Lake Ontario via the Erie Barge Canal, a navigation canal that links the Mohawk-Hudson rivers, which drain to the Atlantic Ocean, to Oneida Lake, which drains to Lake Ontario through the Oneida-Oswego rivers. Blueback herring ascend the Hudson River to spawn and were first reported from the upper Mohawk River in 1978. They currently spawn in several of the upper Mohawk's tributaries, including one about 430 km from the ocean but only 25 km from Oneida Lake. They were first found in Oneida Lake in 1982 and, in fall 1994, large numbers of juvenile blueback herring were found moving down the Oswego River. In the southern United States, blueback herring established self-reproducing populations in several reservoirs, and thus they have the potential to colonize Lake Ontario. If blueback herring became established in Lake Ontario, they could spread to other Great Lakes and impede recovery of depressed populations of indigenous fishes, like lake herring (<i>Coregonus artedi</i>) and lake trout (<i>Salvelinus namaycush</i>), through competition with, or predation on, their larvae.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Great Lakes Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/S0380-1330(98)70856-1","usgsCitation":"Owens, R.W., O’Gorman, R., Mills, E.L., Rudstam, L.G., Hasse, J.J., Kulik, B.H., and MacNeill, D.B., 1998, Blueback herring (<i>Alosa aestivalis</i>) in Lake Ontario: First record, entry route, and colonization potential: Journal of Great Lakes Research, v. 24, no. 3, p. 723-730, https://doi.org/10.1016/S0380-1330(98)70856-1.","productDescription":"8 p.","startPage":"723","endPage":"730","numberOfPages":"8","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":479881,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1016/s0380-1330(98)70856-1","text":"Publisher Index Page"},{"id":267252,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/S0380-1330(98)70856-1"},{"id":133210,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"24","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a01e4b07f02db5f8006","contributors":{"authors":[{"text":"Owens, Randall W.","contributorId":23871,"corporation":false,"usgs":true,"family":"Owens","given":"Randall","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":309094,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"O’Gorman, Robert rogorman@usgs.gov","contributorId":3451,"corporation":false,"usgs":true,"family":"O’Gorman","given":"Robert","email":"rogorman@usgs.gov","affiliations":[],"preferred":true,"id":309092,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Mills, Edward L.","contributorId":61387,"corporation":false,"usgs":true,"family":"Mills","given":"Edward","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":309097,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Rudstam, Lars G.","contributorId":56609,"corporation":false,"usgs":false,"family":"Rudstam","given":"Lars","email":"","middleInitial":"G.","affiliations":[{"id":12722,"text":"Cornell University","active":true,"usgs":false}],"preferred":false,"id":309096,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Hasse, John J.","contributorId":78292,"corporation":false,"usgs":true,"family":"Hasse","given":"John","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":309098,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Kulik, Brandon H.","contributorId":20291,"corporation":false,"usgs":true,"family":"Kulik","given":"Brandon","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":309093,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"MacNeill, David B.","contributorId":34474,"corporation":false,"usgs":true,"family":"MacNeill","given":"David","email":"","middleInitial":"B.","affiliations":[],"preferred":false,"id":309095,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

Recent reports, however, suggest that it could play a major role in the evolution and biogeography of recent corals. We investigated the calcification rates of five colonies of the zooxanthellate coral Stylophora pistillata in synthetic seawater using the alkalinity anomaly technique. Changes in aragonite saturation from 98% to 585% were obtained by manipulating the calcium concentration. The results show a nonlinear increase in calcification rate as a function of aragonite saturation level. Calcification increases nearly 3-fold when aragonite saturation increases from 98% to 390%, i.e., close to the typical present saturation state of tropical seawater. There is no further increase of calcification at saturation values above this threshold. Preliminary data suggest that another coral species, Acropora sp., displays a similar behaviour. These experimental results suggest: (l) that the rate of calcification does not change significantly within the range of saturation levels corresponding to the last glacial-interglacial cycle, and (2) that it may decrease significantly in the future as a result of the decrease in the saturation level due to anthropogenic release of CO2 into the atmosphere. Experimental studies that control environmental conditions and seawater composition provide unique opportunities to unravel the response of corals to global environmental changes.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Global and Planetary Change","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/S0921-8181(98)00035-6","issn":"09218181","usgsCitation":"Gattuso, J., Frankignoulle, M., Bourge, I., Romaine, S., and Buddemeier, R., 1998, Effect of calcium carbonate saturation of seawater on coral calcification: Global and Planetary Change, v. 18, no. 1-2, p. 37-46, https://doi.org/10.1016/S0921-8181(98)00035-6.","startPage":"37","endPage":"46","numberOfPages":"10","costCenters":[],"links":[{"id":206566,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/S0921-8181(98)00035-6"},{"id":230235,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"18","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a05c6e4b0c8380cd50f51","contributors":{"authors":[{"text":"Gattuso, J.-P.","contributorId":61194,"corporation":false,"usgs":true,"family":"Gattuso","given":"J.-P.","email":"","affiliations":[],"preferred":false,"id":387665,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Frankignoulle, M.","contributorId":39968,"corporation":false,"usgs":true,"family":"Frankignoulle","given":"M.","email":"","affiliations":[],"preferred":false,"id":387663,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bourge, I.","contributorId":10948,"corporation":false,"usgs":true,"family":"Bourge","given":"I.","email":"","affiliations":[],"preferred":false,"id":387662,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Romaine, S.","contributorId":50684,"corporation":false,"usgs":true,"family":"Romaine","given":"S.","email":"","affiliations":[],"preferred":false,"id":387664,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Buddemeier, R.

Mark-recapture models were used to estimate abundance, which was converted to density using estimates of effective trap area. Tests of model assumptions provided by CAPTURE indicated pronounced heterogeneity in capture probabilities and some indication of behavioral response and variation over time. Mean estimated density was 1.80 mongooses/ha (range, 1.37-2.15/ha) with estimated coefficients of variation of 4.68-11.92% (X?? = 7.46%). Estimates of density based on mark-recapture data depended heavily on assumptions about animal home ranges; variances of densities also may be underestimated, leading to unrealistically narrow confidence intervals. Estimates based on trap webs require fewer assumptions, and estimated variances may be a more realistic representation of sampling variation. Because trap webs are established easily and provide adequate data for estimation in a few sample occasions, the method should be efficient and reliable for estimating densities of mongooses.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Mammalogy","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"00222372","usgsCitation":"Corn, J., and Conroy, M., 1998, Estimation of density of mongooses with capture-recapture and distance sampling: Journal of Mammalogy, v. 79, no. 3, p. 1009-1015.","startPage":"1009","endPage":"1015","numberOfPages":"7","costCenters":[],"links":[{"id":230233,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"79","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0b82e4b0c8380cd52758","contributors":{"authors":[{"text":"Corn, J.L.","contributorId":72964,"corporation":false,"usgs":true,"family":"Corn","given":"J.L.","email":"","affiliations":[],"preferred":false,"id":387654,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Conroy, M.J.","contributorId":84690,"corporation":false,"usgs":true,"family":"Conroy","given":"M.J.","email":"","affiliations":[],"preferred":false,"id":387655,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

During this period, the colony increased from 1,100 to &gt;5,000 nesting pairs. Gosling mass at 30 days of age declined from 764 ± SE of 13 g and 723 ± 15 g for males and females, respectively, in the 1986 cohort, to 665 ± 18 g and 579 ± 18 g in the 1994 cohort. Gosling size was directly negatively correlated with number of Black Brant broods. We detected no trend in adult body size for individuals from these cohorts; in fact, adults from the 1992 and 1994 cohorts had the largest overall masses. Clutch size increased with age from 3.4 eggs for 2-year-old females to 4.4 eggs for 5-year-old females. Clutch size declined during the study by 0.20 (3-year-old females) to 0.45 (2-year-old females) eggs. Clutch size did not decline between the 1986 and 1990 cohorts for females that were &gt;5 years old.

The objective of the present study was to develop a method for determining the potential sublethal effects of contaminants associated with sediment on the amphipod <i>Hyalella azteca</i> (e.g., reproduction). Exposures to sediment were started with 7- to 8-d-old amphipods. On day 28, amphipods were isolated from the sediment and placed in water-only chambers where reproduction was measured on day 35 and 42. Typically, amphipods were first in amplexus at about day 21 to 28 with release of the first brood between day 28 to 42. Endpoints measured included survival (day 28, 35, and 42), growth (as length and weight on day 28 and 42), and reproduction (number of young/female produced from day 28 to 42). This method was used to evaluate a formulated sediment and field-collected sediments with low to moderate concentrations of contaminants. Survival of amphipods in these sediments was typically &gt;85% after the 28-d sediment exposures and the 14-d holding period in water to measure reproduction. Reproduction was more variable than growth; hence, more replicates might be needed to establish statistical differences among treatments. Previous studies have demonstrated that growth of <i>H. azteca</i> in sediment tests often provides unique information that can be used to discriminate toxic effects of exposure to contaminants. Either length or weight can be measured in sediment tests with <i>H. azteca</i>. However, additional statistical options are available if length is measured on individual amphipods, such as nested analysis of variance that can account for variance in length within replicates. Ongoing water-only studies testing select contaminants will provide additional data on the relative sensitivity and variability of sublethal endpoints in toxicity tests with <i>H. azteca</i>.</p>","language":"English","publisher":"Wiley","doi":"10.1002/etc.5620170811","issn":"07307268","usgsCitation":"Ingersoll, C.G., Brunson, E., Dwyer, F.J., Hardesty, D., and Kemble, N.E., 1998, Use of sublethal endpoints in sediment toxicity tests with the amphipod <i>Hyalella azteca</i>: Environmental Toxicology and Chemistry, v. 17, no. 8, p. 1508-1523, https://doi.org/10.1002/etc.5620170811.","productDescription":"16 p.","startPage":"1508","endPage":"1523","costCenters":[],"links":[{"id":489108,"rank":1,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://zenodo.org/record/1236401","text":"External Repository"},{"id":230035,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"17","issue":"8","noUsgsAuthors":false,"publicationDate":"1998-08-01","publicationStatus":"PW","scienceBaseUri":"505bbf8de4b08c986b329c17","contributors":{"authors":[{"text":"Ingersoll, Chris G.","contributorId":48008,"corporation":false,"usgs":true,"family":"Ingersoll","given":"Chris","email":"","middleInitial":"G.","affiliations":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"preferred":false,"id":387600,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Brunson, Eric L. 0000-0001-6624-0902 elbrunson@usgs.gov","orcid":"https://orcid.org/0000-0001-6624-0902","contributorId":3282,"corporation":false,"usgs":true,"family":"Brunson","given":"Eric L.","email":"elbrunson@usgs.gov","affiliations":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"preferred":false,"id":387598,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Dwyer, F.

We show that one main difference between the dynamics of high- and low-stress events is the amount of coseismic temporal rake rotation occurring at given points on the fault. Curved striations on exposed fault surfaces and earthquake dislocation models derived from ground-motion inversion indicate that the slip direction may change with time at a point on the fault during dynamic rupture. We use a 3D boundary integral method to model temporal rake variations during dynamic rupture propagation assuming a slip-weakening friction law and isotropic friction. The points at which the slip rotates most are characterized by an initial shear stress direction substantially different from the average stress direction over the fault plane. We show that for a given value of stress drop, the level of initial shear stress (i.e., the fractional stress drop) determines the amount of rotation in slip direction. We infer that seismic events that show evidence of temporal rake rotations are characterized by a low initial shear-stress level with spatially variable direction on the fault (possibly due to changes in fault surface geometry) and an almost complete stress drop.</p><p>Our models motivate a new interpretation of curved and cross-cutting striations and put new constraints on their analysis. The initial rake is in general collinear with the initial stress at the hypocentral zone, supporting the assumptions made in stress-tensor inversion from first-motion analysis. At other points on the fault, especially away from the hypocenter, the initial slip rake may not be collinear with the initial shear stress, contradicting a common assumption of structural geology. On the other hand, the later part of slip in our models is systematically more aligned with the average stress direction than the early slip. Our modeling suggests that the length of the straight part of curved striations is usually an upper bound of the slip-weakening distance if this parameter is uniform over the fault plane, and the direction of the late part of slip of curved striations should have more weight in the estimate of initial stress direction.</p>","language":"English","publisher":"Seismological Society of America","doi":"10.1785/BSSA0880030777","issn":"00371106","usgsCitation":"Guatteri, M., and Spudich, P., 1998, Coseismic temporal changes of slip direction: The effect of absolute stress on dynamic rupture: Bulletin of the Seismological Society of America, v. 88, no. 3, p. 777-789, https://doi.org/10.1785/BSSA0880030777.","productDescription":"13 p.","startPage":"777","endPage":"789","costCenters":[],"links":[{"id":229995,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.er.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"88","issue":"3","noUsgsAuthors":false,"publicationDate":"1998-06-01","publicationStatus":"PW","scienceBaseUri":"5059fc5de4b0c8380cd4e252","contributors":{"authors":[{"text":"Guatteri, Mariagiovanna","contributorId":29979,"corporation":false,"usgs":true,"family":"Guatteri","given":"Mariagiovanna","email":"","affiliations":[],"preferred":false,"id":387594,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Spudich, P.","contributorId":85700,"corporation":false,"usgs":true,"family":"Spudich","given":"P.","affiliations":[],"preferred":false,"id":387595,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Live unionids at four stations along the southeastern shore accounted for 97% (20 species) of all shells collected in 1982–1983, whereas live unionids accounted for only 10% (13 species) in 1992. A similar decline in live unionids occurred at nine stations along the northwestern shore, except the decline occurred over the three sampling periods: in 1982–83, 84% (22 species) were live; in 1992, 65% (26 species) were live; and, in 1994, only 3% (13 species) were live. The difference in time to near-total mortality of unionids along the southeastern and northwestern shores is attributed to differences in the time of invasion and abundance of zebra mussel veligers in distinct water masses emanating from Lake St. Clair located immediately upstream of the Detroit River. Although individuals of all species of all unionid subfamilies declined between 1982 and 1992/1994, members of the subfamilies Anodontinae and Lampsilinae declined more than Ambleminae. Between 1986 and 1992/1994, five Anodontinae, three Lampsilinae and 0 Ambleminae species have been extirpated from the river due to dreissenid mussel infestation. Numbers of individuals of commonly found species declined more than numbers of individuals of uncommonly found species. However, the number of uncommon species declined 47% (17 to 9) along both the southeastern and northwestern shores, whereas common species remained the same (3 species) along the southeastern shore and declined only 40% (5 to 3 species) along the northwestern shore. This study, and others, suggest that high mortality of unionids can occur between 4 and 6 yr after initial invasion by dreissenids or up to 8 yr depending on water current patterns. Infestation-induced mortality of unionids in the Detroit River is similar to that observed at a few locations in other rivers, but is higher over a larger area than that measured in other rivers to date, probably because the Detroit River was the first to be colonized by dreissenid mussels in North America.</span></p>","language":"English","publisher":"University of Notre Dame","doi":"10.1674/0003-0031(1998)140[0299:IOZAQM]2.0.CO;2","usgsCitation":"Schloesser, D.W., Kovalak, W., Longton, G., Ohnesorg, K.L., and Smithee, R., 1998, Impact of zebra and quagga mussels (Dreissena spp.) on freshwater unionids (Bivalvia: Unionidae) in the Detroit River of the Great Lakes: American Midland Naturalist, v. 140, no. 2, p. 299-313, https://doi.org/10.1674/0003-0031(1998)140[0299:IOZAQM]2.0.CO;2.","productDescription":"14 p.","startPage":"299","endPage":"313","numberOfPages":"14","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":133503,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Canada, United States","state":"Michigan, Ontario","otherGeospatial":"Detroit River","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -82.90279575770897,\n              42.334312355926215\n            ],\n            [\n              -82.91682894262999,\n              42.37320178206187\n            ],\n            [\n              -83.04312760691857,\n              42.34209216624515\n            ],\n            [\n              -83.12498785229053,\n              42.2772310055276\n            ],\n            [\n              -83.1530542221326,\n              42.24174531837852\n            ],\n            [\n              -83.15773195043921,\n              42.215767530130364\n            ],\n            [\n              -83.20333980143211,\n              42.08137867797771\n            ],\n            [\n              -83.1121240994463,\n              42.06835816567923\n            ],\n            [\n              -83.1039380749093,\n              42.14817525295584\n            ],\n            [\n              -83.0934131862181,\n              42.18458007326123\n            ],\n            [\n              -83.1004297786789,\n              42.25126782872945\n            ],\n            [\n              -83.08639659375788,\n              42.28847839494202\n            ],\n            [\n              -83.05716079183904,\n              42.31356148959915\n            ],\n            [\n              -82.99050316346491,\n              42.3248023917769\n            ],\n            [\n              -82.94138701624163,\n              42.332583378478205\n            ],\n            [\n              -82.90279575770897,\n              42.334312355926215\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"140","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49f4e4b07f02db5f046b","contributors":{"authors":[{"text":"Schloesser, D.
