Calculation of the relative humidity based on estimates of yearly averages of water-vapor pressures and temperatures at the Martian surface was used for this purpose. Water ice was found to be sufficiently unstable everywhere within 45?? of the equator that if the observed WEH is due to water ice, it requires a low-permeability cover layer near the surface to isolate the water ice below from the atmosphere above. In contrast, epsomite or hexahydrite may be stable in many near-equatorial locations where significant amounts of WEH are observed.

Oleic acid and methyl oleate have been the most troublesome of these impurities because of their relatively high concentrations in triolein and because significant residues of both can persist even after size exclusion chromatographic (SEC) fractionation. These residues have also been blamed for false-positive signals during bioindicator testing of SPMD dialysates. To prevent these problems, a simple, cost-effective procedure was developed for purifying triolein destined for use in SPMDs: the bulk triolein is repeatedly (6×) partitioned against methanol. Tests of the procedure show that </span><sup>14</sup><span>C-oleic acid is completely removed from the triolein. After SEC fractionation, dialysates of standard-size SPMDs made with the purified triolein contain less than 5 μg of methyl oleate as compared to sometimes more than 500 μg for dialysates (also after SEC) of SPMDs made with unpurified triolein. Gas chromatographic analyses with flame ionization and electron capture detection show that the purification treatment also greatly reduces the number and size of peaks caused by unidentified contaminants in the triolein. Microtox basic assay of dialysates of SPMDs shows that those made with the purified triolein have lower acute toxicities than dialysates of SPMDs made with unpurified triolein. Yeast estrogen screen (YES) testing of SPMDs fabricated with unpurified and purified triolein demonstrates that the purification process removes all background estrogenic activity.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.chemosphere.2003.09.014","issn":"00456535","usgsCitation":"Lebo, J., Almeida, F., Cranor, W., Petty, J.D., Huckins, J., Rastall, A., Alvarez, D., Mogensen, B., and Johnson, B., 2004, Purification of triolein for use in semipermeable membrane devices (SPMDs): Chemosphere, v. 54, no. 8, p. 1217-1224, https://doi.org/10.1016/j.chemosphere.2003.09.014.","productDescription":"8 p.","startPage":"1217","endPage":"1224","numberOfPages":"8","costCenters":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"links":[{"id":235093,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":208962,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.chemosphere.2003.09.014"}],"volume":"54","issue":"8","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a9040e4b0c8380cd7fc16","contributors":{"authors":[{"text":"Lebo, J.A.","contributorId":65533,"corporation":false,"usgs":true,"family":"Lebo","given":"J.A.","affiliations":[],"preferred":false,"id":412439,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Almeida, F.V.","contributorId":21325,"corporation":false,"usgs":true,"family":"Almeida","given":"F.V.","email":"","affiliations":[],"preferred":false,"id":412435,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Cranor, W.L.","contributorId":98261,"corporation":false,"usgs":true,"family":"Cranor","given":"W.L.","affiliations":[],"preferred":false,"id":412441,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Petty, J.

To investigate the relative roles of chemical and temporal controls in generating these contrasting liquid lines of descent we have undertaken a detailed study of tholeiitic lavas from Akutan volcano in the oceanic A1eutian arc and calc-alkaline products from Aniakchak volcano on the continental A1askan Peninsula. The differences do not appear to be linked to parental magma composition. The Akutan lavas can be explained by closed-system magmatic evolution, whereas curvilinear trace element trends and a large range in 87 Sr/86 Sr isotope ratios in the Aniakchak data appear to require the combined effects of fractional crystallization, assimilation and magma mixing. Both magmatic suites preserve a similar range in 226 Ra-230 Th disequilibria, which suggests that the time scale of crustal residence of magmas beneath both these volcanoes was similar, and of the order of several thousand years. This is consistent with numerical estimates of the time scales for crystallization caused by cooling in convecting crustal magma chambers. During that time interval the tholeiitic Akutan magmas underwent restricted, closed-system, compositional evolution. In contrast, the calc-alkaline magmas beneath Aniakchak volcano underwent significant open-system compositional evolution. Combining these results with data from other studies we suggest that differentiation is faster in calc-alkaline and potassic magma series than in tholeiitic series, owing to a combination of greater extents of assimilation, magma mixing and cooling.","language":"English","doi":"10.1093/petrology/egg086","issn":"00223530","usgsCitation":"George, R., Turner, S., Hawkesworth, C., Bacon, C., Nye, C., Stelling, P., and Dreher, S., 2004, Chemical versus temporal controls on the evolution of tholeiitic and calc-alkaline magmas at two volcanoes in the Alaska-Aleutian arc: Journal of Petrology, v. 45, no. 1, p. 203-219, https://doi.org/10.1093/petrology/egg086.","productDescription":"17 p.","startPage":"203","endPage":"219","numberOfPages":"17","costCenters":[{"id":615,"text":"Volcano Hazards Program","active":true,"usgs":true},{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":478094,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1093/petrology/egg086","text":"Publisher Index Page"},{"id":235295,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"45","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f598e4b0c8380cd4c2e5","contributors":{"authors":[{"text":"George, R.","contributorId":65269,"corporation":false,"usgs":true,"family":"George","given":"R.","email":"","affiliations":[],"preferred":false,"id":412367,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Turner, S.","contributorId":18947,"corporation":false,"usgs":true,"family":"Turner","given":"S.","email":"","affiliations":[],"preferred":false,"id":412363,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hawkesworth, C.","contributorId":20489,"corporation":false,"usgs":true,"family":"Hawkesworth","given":"C.","email":"","affiliations":[],"preferred":false,"id":412364,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Bacon, C.

Shock-produced planar microstructures (PMs) have been identified in quartz grains in several lithologies associated with the structure: sandstones, quartzite pebbles, and breccia. Two distinct types of PMs are present: P1 features, which appear identical to planar fractures (PFs or cleavage), and P2 features, which are interpreted as possible incipient planar deformation features (PDFs). The latter are uniquely produced by the shock waves associated with meteorite impact events. Both types of PMs are oriented parallel to specific crystallographic planes in the quartz, most commonly to <span>c(0001), xi{11 (2) over bar2}, and r/k{10 (1) over bar1}</span>. The association of unusual, structurally deformed strata with distinct shock-produced microdeformation features in their quartz-bearing rocks establishes Rock Elm as a meteorite impact structure and supports the view that the presence of multiple parallel cleavages in quartz may be used independently as a criterion for meteorite impact.

A similar age estimate (450-400 Ma) is obtained independently by combining the results of studies of the general morphology of complex impact structures with estimated rates of sedimentation for the region.

This research has focused on vulnerable base-poor systems; catchments on alkaline lithologies have received little attention. In regions of high acid loadings, however, even well-buffered catchments are susceptible to forest decline and episodes of low alkalinity in streamwater. As part of a collaboration between the Czech and U.S. Geological Surveys, we compared biogeochemical patterns in two well-studied, well-buffered catchments: Pluhuv Bor in the western Czech Republic, which has received high loading of atmospheric acidity, and Sleepers River Research Watershed in Vermont, U.S.A., where acid loading has been considerably less. Despite differences in lithology, wetness, forest type, and glacial history, the catchments displayed similar patterns of solute concentrations and flow. At both catchments, base cation and alkalinity diluted with increasing flow, whereas nitrate and dissolved organic carbon increased with increasing flow. Sulfate diluted with increasing flow at Sleepers River, while at Pluhuv Bor the sulfate-flow relation shifted from positive to negative as atmospheric sulfur (S) loadings decreased and soil S pools were depleted during the 1990s. At high flow, alkalinity decreased to near 100 μeq L<sup>-1</sup><span>&nbsp;</span>at Pluhuv Bor compared to 400 μeq L<sup>-1</sup><span>&nbsp;</span>at Sleepers River. Despite the large amounts of S flushed from Pluhuv Bor soils, these alkalinity declines were caused solely by dilution, which was greater at Pluhuv Bor relative to Sleepers River due to greater contributions from shallow flow paths at high flow. Although the historical high S loading at Pluhuv Bor has caused soil acidification and possible forest damage, it has had little effect on the acid/base status of streamwater in this well-buffered catchment.</p>","language":"English","publisher":"Springer","doi":"10.1023/B:WAFO.0000028363.48348.a4","issn":"15677230","usgsCitation":"Shanley, J.B., Kram, P., Hruska, J., and Bullen, T., 2004, A biogeochemical comparison of two well-buffered catchments with contrasting histories of acid deposition: Water, Air, and Soil Pollution: Focus, v. 4, no. 2-3, p. 325-342, https://doi.org/10.1023/B:WAFO.0000028363.48348.a4.","productDescription":"18 p.","startPage":"325","endPage":"342","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":235628,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":209322,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1023/B:WAFO.0000028363.48348.a4"}],"volume":"4","issue":"2-3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e327e4b0c8380cd45e48","contributors":{"authors":[{"text":"Shanley, J.

These plutons postdate some deformation related to a major contractional event between the previously amalgamated Wrangellia and Alexander terranes and the previously accreted terranes of the North American margin. We studied the aureole mineral assemblages of these plutons near Petersburg, Alaska, determined pressure and temperature of equilibration, and examined structures that developed within and adjacent to these plutons. Parallelism of magmatic and submagmatic fabrics with fabrics in the country rock indicates synchroneity of pluton emplacement with regional deformation and suggests that magma transport to higher crustal levels was assisted by regional deformation. Replacement of andalusite by kyanite or sillimanite indicates crustal thickening soon after pluton emplacement. Regional structural analysis indicates the crustal thickening was accomplished by thrust burial. Thermobarometric analyses indicate the aureoles reached near-peak temperatures of 525 to 635 ??C at pressures of 570 to 630 MPa. Consideration of the rate of thermal decay of the aureoles suggests that burial was rapid and occurred at rates around 5 to 8 mm/year. Structural observations indicate there was contractional deformation before, during, and after emplacement of the 90-Ma plutons.

Yosemite National Park is one of the largest and best-known parks in the United States, harbouring significant cultural and ecological resources. Effective management of non-natives would be greatly assisted by information on their potential distribution that can be generated by predictive modelling techniques. Our goal was to identify key environmental factors that were correlated with the percent cover of non-native species and then develop a predictive model using the Genetic Algorithm for Rule-set Production technique. We performed a series of analyses using community-level data on species composition in 236 plots located throughout the park. A total of 41 non-native species were recorded which occurred in 23.7% of the plots. Plots with non-natives occurred most frequently at low- to mid-elevations, in flat areas with other herbaceous species. Based on the community-level results, we selected elevation, slope, and vegetation structure as inputs into the GARP model to predict the environmental niche of non-native species. Verification of results was performed using plot data reserved from the model, which calculated the correct prediction of non-native species occurrence as 76%. The majority of the western, lower-elevation portion of the park was predicted to have relatively low levels of non-native species occurrence, with highest concentrations predicted at the west and south entrances and in the Yosemite Valley. Distribution maps of predicted occurrences will be used by management to: efficiently target monitoring of non-native species, prioritize control efforts according to the likelihood of non-native occurrences, and inform decisions relating to the management of non-native species in postfire environments. Our approach provides a valuable tool for assisting decision makers to better manage non-native species, which can be readily adapted to target non-native species in other locations.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Diversity and Distributions","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1366-9516.2004.00093.x","issn":"13669516","usgsCitation":"Underwood, E., Klinger, R., and Moore, P., 2004, Predicting patterns of non-native plant invasions in Yosemite National Park, California, USA: Diversity and Distributions, v. 10, no. 5-6, p. 447-459, https://doi.org/10.1111/j.1366-9516.2004.00093.x.","startPage":"447","endPage":"459","numberOfPages":"13","costCenters":[],"links":[{"id":489885,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1111/j.1366-9516.2004.00093.x","text":"Publisher Index Page"},{"id":209082,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1366-9516.2004.00093.x"},{"id":235274,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"10","issue":"5-6","noUsgsAuthors":false,"publicationDate":"2004-09-06","publicationStatus":"PW","scienceBaseUri":"505a81c0e4b0c8380cd7b6eb","contributors":{"authors":[{"text":"Underwood, E.C.","contributorId":47134,"corporation":false,"usgs":true,"family":"Underwood","given":"E.C.","email":"","affiliations":[],"preferred":false,"id":411048,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Klinger, R.","contributorId":78493,"corporation":false,"usgs":true,"family":"Klinger","given":"R.","email":"","affiliations":[],"preferred":false,"id":411050,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Moore, P.E.","contributorId":57395,"corporation":false,"usgs":true,"family":"Moore","given":"P.E.","email":"","affiliations":[],"preferred":false,"id":411049,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

We examined three physiologically and phylogenetically diverse species of selenate- and selenite-respiring bacteria, Sulfurospirillum barnesii, Bacillus selenitireducens, and Selenihalanaerobacter shriftii, for the occurrence of this phenomenon. When grown with selenium oxyanions as the electron acceptor, all of these organisms formed extracellular granules consisting of stable, uniform nanospheres (diameter, ???300 nm) of Se(0) having monoclinic crystalline structures. Intracellular packets of Se(0) were also noted. The number of intracellular Se(0) packets could be reduced by first growing cells with nitrate as the electron acceptor and then adding selenite ions to washed suspensions of the nitrate-grown cells. This resulted in the formation of primarily extracellular Se nanospheres. After harvesting and cleansing of cellular debris, we observed large differences in the optical properties (UV-visible absorption and Raman spectra) of purified extracellular nanospheres produced in this manner by the three different bacterial species. The spectral properties in turn differed substantially from those of amorphous Se(0) formed by chemical oxidation of H2Se and of black, vitreous Se(0) formed chemically by reduction of selenite with ascorbate. The microbial synthesis of Se(0) nanospheres results in unique, complex, compacted nanostructural arrangements of Se atoms. These arrangements probably reflect a diversity of enzymes involved in the dissimilatory reduction that are subtly different in different microbes. Remarkably, these conditions cannot be achieved by current methods of chemical synthesis.","language":"English","publisher":"ASM","doi":"10.1128/AEM.70.1.52-60.2004","issn":"00992240","usgsCitation":"Oremland, R., Herbel, M., Blum, J., Langley, S., Beveridge, T., Ajayan, P., Sutto, T., Ellis, A., and Curran, S., 2004, Structural and spectral features of selenium nanospheres produced by Se-respiring bacteria: Applied and Environmental Microbiology, v. 70, no. 1, p. 52-60, https://doi.org/10.1128/AEM.70.1.52-60.2004.","productDescription":"9 p.","startPage":"52","endPage":"60","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":478239,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://www.ncbi.nlm.nih.gov/pmc/articles/321302","text":"External Repository"},{"id":235297,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":209097,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1128/AEM.70.1.52-60.2004"}],"volume":"70","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b9bc3e4b08c986b31d08f","contributors":{"authors":[{"text":"Oremland, R.S.","contributorId":97512,"corporation":false,"usgs":true,"family":"Oremland","given":"R.S.","email":"","affiliations":[],"preferred":false,"id":412493,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Herbel, M.J.","contributorId":57232,"corporation":false,"usgs":true,"family":"Herbel","given":"M.J.","email":"","affiliations":[],"preferred":false,"id":412492,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Blum, J.S.","contributorId":105070,"corporation":false,"usgs":true,"family":"Blum","given":"J.S.","email":"","affiliations":[],"preferred":false,"id":412494,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Langley, S.","contributorId":32342,"corporation":false,"usgs":true,"family":"Langley","given":"S.","email":"","affiliations":[],"preferred":false,"id":412489,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Beveridge, T.J.","contributorId":35524,"corporation":false,"usgs":true,"family":"Beveridge","given":"T.J.","email":"","affiliations":[],"preferred":false,"id":412490,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Ajayan, P.M.","contributorId":51073,"corporation":false,"usgs":true,"family":"Ajayan","given":"P.M.","email":"","affiliations":[],"preferred":false,"id":412491,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Sutto, T.","contributorId":30012,"corporation":false,"usgs":true,"family":"Sutto","given":"T.","email":"","affiliations":[],"preferred":false,"id":412488,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Ellis, A.V.","contributorId":21741,"corporation":false,"usgs":true,"family":"Ellis","given":"A.V.","email":"","affiliations":[],"preferred":false,"id":412486,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Curran, S.","contributorId":22125,"corporation":false,"usgs":true,"family":"Curran","given":"S.","email":"","affiliations":[],"preferred":false,"id":412487,"contributorType":{"id":1,"text":"Authors"},"rank":9}]}}

Submarine slope failures and active faults, either of which could have generated a tsunami, are known on the shelf and slope near Long Beach. Large slope failures are present on the San Pedro Escarpment and on the basin slope adjacent to the San Pedro shelf. The southeastern part of the escarpment has had a long history of slope failure. The most recent failure, the Palos Verdes slide, is over 4.5 km long, has been dated as 7500 years old, and involved over 0.34 km 3 of material, which now litters the adjacent basin floor. Other, smaller, deposits from nearby failures are also present, as are buried wedges of debris that indicate slope failures have occurred locally throughout the Holocene and much of the late Pleistocene. Slope failures have occurred in response to continual Quaternary uplift of the Palos Verdes anticlinorium. The Palos Verdes slide could potentially have generated a failure-related tsunami with an amplitude in the range of 8-12 m because it apparently failed catastrophically, started in shallow water, evolved on low-drag bedding planes, had a long slide path, and involved high-strength lithified material. ?? 2003 Elsevier B.V.

We conclude that during major glaciations extremely thick pack ice or ice shelves covered the western Arctic Ocean and its circulation was restricted in comparison with interglacial, modern-type conditions. Glacier collapse events are marked in sediment cores by increased contents of ice-rafted debris, notably by spikes of detrital carbonates and iron oxide grains from the Canadian Arctic Archipelago. Composition of foraminiferal calcite ?? 18O and ??13C also shows strong cyclicity indicating changes in freshwater balance and/or ventilation rates of the Arctic Ocean. Light stable isotopic spikes characterize deglacial events such as the last deglaciation at ca. 12 14C kyr BP. The prolonged period with low ??18O and ??13C values and elevated contents of iron oxide grains from the Canadian Archipelago in the lower part of the Mendeleev Ridge record is interpreted to signify the pooling of freshwater in the Amerasia Basin, possibly in relation to an extended glaciation in arctic North America. Unique benthic foraminiferal events provide a means for an independent stratigraphic correlation of sedimentary records from the Mendeleev Ridge and other mid-depth locations throughout the Arctic Ocean such as the Northwind and Lomonosov Ridges. This correlation demonstrates the disparity of existing age models and underscores the need to establish a definitive chronostratigraphy for Arctic Ocean sediments. ?? 2003 Elsevier B.V.

Larger numbers of adult fish and more redds were observed in the 2 modified streams compared with the 2 streams with little or no modification. Most spawning occurred on constructed riffles with small gravel and over a narrow range of depths and velocities.

Simulated input water evaporation can be used as a technique to quantitatively assess the potential for scale formation in RO desalination systems. The technique was demonstrated by simulating the increase in solute concentrations required to form calcite, gypsum, and amorphous silica scales at 25??C and 40??C from 23 desalination input waters taken from the literature. Simulation results could be used to quantitatively assess the potential of a given input water to form scale or to compare the potential of a number of input waters to form scale during RO desalination. Simulated evaporation of input waters cannot accurately predict the conditions under which scale will form owing to the effects of potentially stable supersaturated solutions, solution velocity, and residence time inside RO systems. However, the simulated scale-forming potential of proposed input waters could be compared with the simulated scale-forming potentials and actual scale-forming properties of input waters having documented operational histories in RO systems. This may provide a technique to estimate the actual performance and suitability of proposed input waters during RO.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Desalination","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/S0011-9164(04)90030-6","issn":"00119164","usgsCitation":"Huff, G.F., 2004, Use of simulated evaporation to assess the potential for scale formation during reverse osmosis desalination: Desalination, v. 160, no. 3, p. 285-292, https://doi.org/10.1016/S0011-9164(04)90030-6.","startPage":"285","endPage":"292","numberOfPages":"8","costCenters":[],"links":[{"id":209171,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/S0011-9164(04)90030-6"},{"id":235409,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"160","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bbf7be4b08c986b329ba8","contributors":{"authors":[{"text":"Huff, G.

Therefore, the objectives of this study were to evaluate the seasonal and diel differences in movement rates, site fidelity, and home range of bluegills in a shallow, natural Great Plains lake. A total of 78 bluegills (200-273 mm total length) were implanted with radio transmitters in March and May 2000. Of these fish, 10 males and 10 females were randomly selected and located every 2 h during one 24-h period each month from April to September 2000. Bluegill movement peaked during midsummer: however, there was little difference in diel movements, suggesting relatively consistent movement throughout the 24-h period. Home range estimates (which included the 24-h tracking plus an additional six locations from the same fish located once per day for six consecutive days each month) ranged up to 172 ha, probably because only about half of the bluegills exhibited site fidelity during any month sampled. Bluegill movement did not appear to be strongly linked with water temperature, barometric pressure, or wind speed. These results suggest that bluegills move considerable distances and that many roam throughout this 332-ha shallow lake. However, diel patterns were not evident. Sampling bluegills in Great Plains lakes using passive gears (e.g., trap nets) may be most effective during the summer months, when fish are most active. Active sampling (e.g., electrofishing) may be more effective than the use of passive gears in spring and fall, when bluegills are less active.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"North American Journal of Fisheries Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1577/M03-004","issn":"02755947","usgsCitation":"Paukert, C., Willis, D., and Bouchard, M., 2004, Movement, home range, and site fidelity of bluegills in a Great Plains Lake: North American Journal of Fisheries Management, v. 24, no. 1, p. 154-161, https://doi.org/10.1577/M03-004.","startPage":"154","endPage":"161","numberOfPages":"8","costCenters":[],"links":[{"id":235558,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":209273,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1577/M03-004"}],"volume":"24","issue":"1","noUsgsAuthors":false,"publicationDate":"2004-02-01","publicationStatus":"PW","scienceBaseUri":"505a5f31e4b0c8380cd70e19","contributors":{"authors":[{"text":"Paukert, C.P.","contributorId":10151,"corporation":false,"usgs":true,"family":"Paukert","given":"C.P.","email":"","affiliations":[],"preferred":false,"id":412543,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Willis, D.W.","contributorId":56179,"corporation":false,"usgs":true,"family":"Willis","given":"D.W.","email":"","affiliations":[],"preferred":false,"id":412545,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bouchard, M.A. 0000-0002-6353-3491","orcid":"https://orcid.org/0000-0002-6353-3491","contributorId":13023,"corporation":false,"usgs":true,"family":"Bouchard","given":"M.A.","affiliations":[],"preferred":false,"id":412544,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

To demonstrate this point, output from a global-scale numerical weather prediction model is used in a stepwise multiple linear regression approach to downscale precipitation and temperature to individual stations located in and around four study basins in the United States. Output from the forecast model is downscaled for lead times up to 14 days. Residuals in the regression equation are modeled stochastically to provide 100 ensemble forecasts. The precipitation and temperature ensembles from this approach have a poor representation of the spatial variability and temporal persistence. The spatial correlations for downscaled output are considerably lower than observed spatial correlations at short forecast lead times (e.g., less than 5 days) when there is high accuracy in the forecasts. At longer forecast lead times, the downscaled spatial correlations are close to zero. Similarly, the observed temporal persistence is only partly present at short forecast lead times. A method is presented for reordering the ensemble output in order to recover the space-time variability in precipitation and temperature fields. In this approach, the ensemble members for a given forecast day are ranked and matched with the rank of precipitation and temperature data from days randomly selected from similar dates in the historical record. The ensembles are then reordered to correspond to the original order of the selection of historical data.

Hydrologic variables in marsh ponds of the Gulf Coast Chenier Plain are potentially affected by structural marsh management (SMM: levees, water control structures and impoundments) that has been implemented since the 1950s. Assuming that SMM restricts tidal flows and drainage of rainwater, we predicted that SMM would increase water depth, and concomitantly decrease salinity and transparency in impounded marsh ponds. We also predicted that SMM would increase seasonal variability in water depth in impounded marsh ponds because of the potential incapacity of water control structures to cope with large flooding events. In addition, we predicted that SMM would decrease spatial variability in water depth. Finally, we predicted that ponds of impounded freshwater (IF), oligohaline (IO), and mesohaline (IM) marshes would be similar in water depth, temperature, dissolved oxygen (<span>O</span><sub>2</sub>), and transparency. Using a priori multivariate analysis of variance (MANOVA) contrast, we tested these predictions by comparing hydrologic variables within ponds of impounded and unimpounded marshes during winters 1997-1998 to 1999-2000 on Rockefeller State Wildlife Refuge, near Grand Chenier, Louisiana. Specifically, we compared hydrologic variables (1) between IM and unimpounded mesohaline marsh ponds (UM); and (2) among IF, IO, and IM marshes ponds. As predicted, water depth was higher and salinity and <span>O</span><sub>2</sub> were lower in IM than in UM marsh ponds. However, temperature and transparency did not differ between IM and UM marsh ponds. Water depth varied more among months in IM marsh ponds than within those of UM marshes, and variances among and within ponds were lower in IM than UM marshes. Finally, all hydrologic variables, except salinity, were similar among IF, IO, and IM marsh ponds. Hydrologic changes within marsh ponds due to SMM should (1) promote benthic invertebrate taxa that tolerate low levels of <span>O</span><sub>2</sub> and salinity; (2) deter waterbird species that cannot cope with increased water levels; and (3) reduce waterbird species diversity by decreasing spatial variability in water depth among and within marsh ponds.</p>","language":"English","publisher":"Inter-Research Science Publisher","doi":"10.3354/meps266035","usgsCitation":"Bolduc, F., and Afton, A., 2004, Hydrologic aspects of marsh ponds during winter on the Gulf Coast Chenier Plain, USA: Effects of structural marsh management: Marine Ecology Progress Series, v. 266, p. 35-42, https://doi.org/10.3354/meps266035.","productDescription":"8 p.","startPage":"35","endPage":"42","costCenters":[{"id":368,"text":"Louisiana Cooperative Fish and Wildlife Research Unit","active":false,"usgs":true}],"links":[{"id":487480,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.3354/meps266035","text":"Publisher Index Page"},{"id":235374,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Louisiana","city":"Grand Chenier","otherGeospatial":"Rockefeller State Wildlife Refuge","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -93.04595947265625,\n              29.709524917923563\n            ],\n            [\n              -92.90657043457031,\n              29.709524917923563\n            ],\n            [\n              -92.90657043457031,\n              29.791792350311347\n            ],\n            [\n              -93.04595947265625,\n              29.791792350311347\n            ],\n            [\n              -93.04595947265625,\n              29.709524917923563\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"266","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a356de4b0c8380cd5fef4","contributors":{"authors":[{"text":"Bolduc, F.","contributorId":76444,"corporation":false,"usgs":true,"family":"Bolduc","given":"F.","email":"","affiliations":[],"preferred":false,"id":412506,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Afton, A.

Geometries for both current and future missions are evaluated, and their abilities to resolve the displacement vector are compared. The north component is always the most difficult to determine using data from near-polar orbiting satellites. However, a satellite with an inclination of about 60°/120° would enable all three components to be well resolved. We attempt to resolve the 3D displacements for the 23 October 2002 Nenana Mountain (Alaska) Earthquake. The north component's error is much larger than the signal, but proxies for eastward and vertical motion can be determined if the north component is assumed negligible.

In this study, we evaluate the water table fluctuations in the floodplain near an incised stream (Walnut Creek, Iowa) and investigate the roles that channel incision and variable recharge play in modifying the water table configuration in the floodplain. Groundwater flows from higher landscape positions towards Walnut Creek under hydraulic gradients that were steepest near the upland/floodplain contact and in the near-stream riparian zone. Annually, water table fluctuations on the floodplain were greatest in wells located 30 m from the creek, midway between the creek and upland. Water levels monitored continuously during a runoff event indicated that bank storage was confined to a narrow zone adjacent to the channel. A steady-state, one-dimensional analytical model was developed to describe the shape of the water table surface near an incised stream and evaluate how variable groundwater recharge and channel bed lowering has affected the shape of the water table surface. Results from this study have implications for managing the riparian buffers of incised streams with successful establishment dependent upon matching buffer vegetation to riparian water table conditions. ?? 2003 Elsevier B.V.
