Previous studies have indicated that arsenic occurs naturally in these aquifers in association with metal-(hydr)oxides and is released to groundwater under reducing conditions generated by microbial oxidation of organic matter. Despite this delineation of the arsenic source and mechanism of arsenic mobilization, identification of arsenic-impacted aquifers is hindered by the heterogeneous and discontinuous nature of glacial sediments. In much of the Midwest, the hydrostratigraphy of glacial deposits is not sufficiently characterized to predict where elevated arsenic concentrations are likely to occur. This case study from southeast Wisconsin presents a detailed characterization of local stratigraphy, hydrostratigraphy, and geochemistry of the Pleistocene glacial deposits and underlying Silurian dolomite. Analyses of a single core, water chemistry data, and well construction reports enabled identification of two aquifers separated by an organic-rich aquitard. The upper, unconfined aquifer provides potable water, whereas arsenic generally exceeds 10 ??g/L in the deeper aquifer. Although coring and detailed hydrostratigraphic characterization are often considered impractical, our results demonstrate that a single core improved interpretation of the complex lithology and hydrostratigraphy. This detailed characterization of hydrostratigraphy facilitated development of well construction guidelines and lays the ground work for further studies of the complex interactions among aquifer sediments, hydrogeology, water chemistry, and microbiology that lead to elevated arsenic in groundwater.

To avoid extinction, tree populations must tolerate, adapt, or migrate. Here we investigate geographic patterns of genetic variation in valley oak,<span>&nbsp;</span><i>Quercus lobata</i><span>&nbsp;</span>Née, to assess how underlying genetic structure of populations might influence this species’ ability to survive climate change. First, to understand how genetic lineages shape spatial genetic patterns, we examine historical patterns of colonization. Second, we examine the correlation between multivariate nuclear genetic variation and climatic variation. Third, to illustrate how geographic genetic variation could interact with regional patterns of 21st Century climate change, we produce region‐specific bioclimatic distributions of valley oak using Maximum Entropy (MAXENT) models based on downscaled historical (1971–2000) and future (2070–2100) climate grids. Future climatologies are based on a moderate‐high (A2) carbon emission scenario and two different global climate models. Chloroplast markers indicate historical range‐wide connectivity via colonization, especially in the north. Multivariate nuclear genotypes show a strong association with climate variation that provides opportunity for local adaptation to the conditions within their climatic envelope. Comparison of regional current and projected patterns of climate suitability indicates that valley oaks grow in distinctly different climate conditions in different parts of their range. Our models predict widely different regional outcomes from local displacement of a few kilometres to hundreds of kilometres. We conclude that the relative importance of migration, adaptation, and tolerance are likely to vary widely for populations among regions, and that late 21st Century conditions could lead to regional extinctions.</p></div></div>","language":"English","publisher":"Blackwell Publishing","doi":"10.1111/j.1365-294X.2010.04726.x","issn":"09621083","usgsCitation":"Sork, V.L., Davis, F., Westfall, R.,

The primary mega-file data-cube (MFDC), comparable to a hyper-spectral data cube, used in this study consisted of 952 bands of data in a single file that were derived from MODIS 500 m, 7-band reflectance data acquired every 8-days during 2001-2003. The methods consisted of (a) segmenting the 952-band MFDC based not only on elevation-precipitation-temperature zones but on major and minor irrigated command area boundaries obtained from India's Central Board of Irrigation and Power (CBIP), (b) developing a large ideal spectral data bank (ISDB) of irrigated areas for India, (c) adopting quantitative spectral matching techniques (SMTs) such as the spectral correlation similarity (SCS) R<sup>2</sup>-value, (d) establishing a comprehensive set of protocols for class identification and labeling, and (e) comparing the results with the National Census data of India and field-plot data gathered during this project for determining accuracies, uncertainties and errors. The study produced irrigated area maps and statistics of India at the national and the subnational (e.g., state, district) levels based on MODIS data from 2001-2003. The Total Area Available for Irrigation (TAAI) and Annualized Irrigated Areas (AIAs) were 113 and 147 million hectares (MHa), respectively. The TAAI does not consider the intensity of irrigation, and its nearest equivalent is the net irrigated areas in the Indian National Statistics. The AIA considers intensity of irrigation and is the equivalent of \"irrigated potential utilized (IPU)\" reported by India's Ministry of Water Resources (MoWR). The field-plot data collected during this project showed that the accuracy of TAAI classes was 88% with a 12% error of omission and 32% of error of commission. Comparisons between the AIA and IPU produced an R<sup>2</sup>-value of 0.84. However, AIA was consistently higher than IPU. The causes for differences were both in traditional approaches and remote sensing. The causes of uncertainties unique to traditional approaches were (a) inadequate accounting of minor irrigation (groundwater, small reservoirs and tanks), (b) unwillingness to share irrigated area statistics by the individual Indian states because of their stakes, (c) absence of comprehensive statistical analyses of reported data, and (d) subjectivity involved in observation-based data collection process. The causes of uncertainties unique to remote sensing approaches were (a) irrigated area fraction estimate and related sub-pixel area computations and (b) resolution of the imagery. The causes of uncertainties common in both traditional and remote sensing approaches were definitions and methodological issues. ?? 2009 International Society for Photogrammetry and Remote Sensing, Inc.

Consequently, we hypothesize, in a subterranean estuary, biogeochemical reactions of Fe respond to submarine groundwater discharge (SGD) and&nbsp;sea level rise.&nbsp;Porewater&nbsp;and sediment samples were collected across a 30-m wide freshwater discharge zone of the Indian River Lagoon (Florida, USA) subterranean estuary, and at a site 250</span>&nbsp;m offshore. Porewater Fe concentrations range from 0.5&nbsp;μM at the shoreline and 250&nbsp;m offshore to about 286&nbsp;<span>μM at the freshwater–saltwater boundary. Sediment sulfur and porewater sulfide maxima occur in near-surface OC-rich black sediments of marine origin, and dissolved Fe maxima occur in underlying OC-poor orange sediments of&nbsp;terrestrial origin. Freshwater SGD flow rates decrease offshore from around 1 to 0.1</span>&nbsp;cm/day, while bioirrigation exchange deepens with distance from about 10&nbsp;cm at the shoreline to about 40&nbsp;<span>cm at the freshwater–saltwater boundary.&nbsp;DOC&nbsp;concentrations increase from around 75</span>&nbsp;μM at the shoreline to as much as 700&nbsp;<span>μM at the freshwater–saltwater boundary as a result of labile marine carbon inputs from marine SGD. This labile DOC reduces Fe-oxides, which in conjunction with slow discharge of SGD at the boundary, allows dissolved Fe to accumulate. Upward&nbsp;advection&nbsp;of fresh SGD carries dissolved Fe from the Fe-oxide reduction zone to the sulfate reduction zone, where dissolved Fe precipitates as Fe-sulfides.

Storm event sampling, which is vital for adequate assessment of water quality in small (wadeable) streams, is typically conducted by manual grab or integrated sampling or with an automated sampler. Although it is typically assumed that samples from a single point adequately represent mean cross-sectional concentrations, especially for dissolved constituents, this assumption of well-mixed conditions has received limited evaluation. Similarly, the impact of temporal (within-storm) concentration variability is rarely considered. Therefore, this study evaluated differences in stormwater quality measured in small streams with several common sampling techniques, which in essence evaluated within-channel and within-storm concentration variability. Constituent concentrations from manual grab samples and from integrated samples were compared for 31 events, then concentrations were also compared for seven events with automated sample collection. Comparison of sampling techniques indicated varying degrees of concentration variability within channel cross sections for both dissolved and particulate constituents, which is contrary to common assumptions of substantial variability in particulate concentrations and of minimal variability in dissolved concentrations. Results also indicated the potential for substantial within-storm (temporal) concentration variability for both dissolved and particulate constituents. Thus, failing to account for potential cross-sectional and temporal concentration variability in stormwater monitoring projects can introduce additional uncertainty in measured water quality data.

This study uses a variety of methods to identify mixtures and a modified concentration-addition approach to estimate their potential toxicity at 845 stream sites across the United States sampled between 1992 and 2001 for organochlorine pesticides and polychlorinated biphenyls (PCBs) in bed sediment. Principal-component (PC) analysis identified five PCs that account for 77% of the total variance in 14 organochlorine compounds in the original dataset. The five PCs represent: (1) chlordane-related compounds and dieldrin; (2)&nbsp;</span><i>p,p′</i><span>-DDT and its degradates; (3)<span>&nbsp;</span></span><i>o,p′</i><span>-DDT and its degradates; (4) the pesticide degradates oxychlordane and heptachlor epoxide; and (5) PCBs. The PC analysis grouped compounds that have similar chemical structure (such as parent compound and degradate), common origin (in the same technical pesticide mixture), and(or) similar relation of concentrations to land use. For example, the highest concentrations of chlordane compounds and dieldrin occurred at urban sites, reflecting past use of parent pesticides for termite control. Two approaches to characterizing mixtures—PC-based mixtures and unique mixtures—were applied to all 299 samples with a detection of two or more organochlorine compounds. PC-based mixtures are defined by the presence (in the sample) of one or more compounds associated with that PC. Unique mixtures are defined as a specific combination of two or more compounds detected in a sample, regardless of how many other compounds were also detected in that sample. The simplest PC-based mixtures (containing compounds from 1 or 2 PCs) commonly occurred in a variety of land use settings. Complex mixtures (containing compounds from 3 or more PCs) were most common in samples from urban and mixed/urban sites, especially in the Northeast, reflecting high concentrations of multiple chlordane, dieldrin, DDT-related compounds, and(or) PCBs. The most commonly occurring unique mixture (</span><i>p,p′</i><span>-DDE,<span>&nbsp;</span></span><i>p,p′</i><span>-DDD) occurred in both simple and complex PC-based mixtures, and at both urban and agricultural sites. Mean Probable Effect Concentration Quotients (PEC-Q) values, which estimate the potential toxicity of organochlorine contaminant mixtures, were highest for complex mixtures. Mean PEC-Q values were highest for urban sites in the Northeast, followed by mixed/urban sites in the Northeast and agricultural sites in cotton growing areas. These results demonstrate that the PEC-Q approach can be used in combination with PC-based and unique mixture analyses to relate potential aquatic toxicity of contaminant mixtures to mixture complexity, land use, and other surrogates for contaminant sources.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.scitotenv.2009.09.052","usgsCitation":"Phillips, P., Nowell, L.H., Gilliom, R.J., Nakagaki, N., Riva-Murray, K., and VanAlstyne, C., 2010, Composition, distribution, and potential toxicity of organochlorine mixtures in bed sediments of streams: Science of the Total Environment, v. 408, no. 3, p. 594-606, https://doi.org/10.1016/j.scitotenv.2009.09.052.","productDescription":"13 p.","startPage":"594","endPage":"606","ipdsId":"IP-009456","costCenters":[{"id":474,"text":"New York Water Science Center","active":true,"usgs":true}],"links":[{"id":345465,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"408","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"59afb7a0e4b0e9bde135114b","contributors":{"authors":[{"text":"Phillips, Patrick J. pjphilli@usgs.gov","contributorId":856,"corporation":false,"usgs":true,"family":"Phillips","given":"Patrick J.","email":"pjphilli@usgs.gov","affiliations":[{"id":474,"text":"New York Water Science Center","active":true,"usgs":true}],"preferred":false,"id":709537,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Nowell, Lisa H. 0000-0001-5417-7264 lhnowell@usgs.gov","orcid":"https://orcid.org/0000-0001-5417-7264","contributorId":490,"corporation":false,"usgs":true,"family":"Nowell","given":"Lisa","email":"lhnowell@usgs.gov","middleInitial":"H.","affiliations":[{"id":451,"text":"National Water Quality Assessment Program","active":true,"usgs":true},{"id":154,"text":"California Water Science Center","active":true,"usgs":true},{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true}],"preferred":true,"id":709538,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Gilliom, Robert J. rgilliom@usgs.gov","contributorId":488,"corporation":false,"usgs":true,"family":"Gilliom","given":"Robert","email":"rgilliom@usgs.gov","middleInitial":"J.","affiliations":[{"id":451,"text":"National Water Quality Assessment Program","active":true,"usgs":true}],"preferred":true,"id":709539,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Nakagaki, Naomi 0000-0003-3653-0540 nakagaki@usgs.gov","orcid":"https://orcid.org/0000-0003-3653-0540","contributorId":1067,"corporation":false,"usgs":true,"family":"Nakagaki","given":"Naomi","email":"nakagaki@usgs.gov","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":true,"id":709540,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Riva-Murray, Karen 0000-0001-6683-2238 krmurray@usgs.gov","orcid":"https://orcid.org/0000-0001-6683-2238","contributorId":168876,"corporation":false,"usgs":true,"family":"Riva-Murray","given":"Karen","email":"krmurray@usgs.gov","affiliations":[{"id":474,"text":"New York Water Science Center","active":true,"usgs":true}],"preferred":true,"id":709541,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"VanAlstyne, Carolyn","contributorId":196180,"corporation":false,"usgs":false,"family":"VanAlstyne","given":"Carolyn","email":"","affiliations":[],"preferred":false,"id":709542,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

These silver tubes containing reference waters may be preferred for calibration of H- and O-bearing materials analyzed with a TC/EA reduction unit. The new sealing apparatus employs a computer controlled stepping motor to produce silver tubes identical in length. The reproducibility of mass of water sealed in tubes (in a range of 200 to 400 µg) can be as good as 1 percent. Although silver tubes sealed with reference waters are robust and can be shaken or heated to 110 °C with no loss of integrity, they should not be frozen because the expansion during the phase transition of water to ice will break the cold seals and all water will be lost. They should be shipped in insulated containers. This new method eliminates air inclusions and isotopic fractionation of water associated with the loading of water into capsules using a syringe. The method is also more than an order of magnitude faster than preparing water samples in ordinary Ag capsules. Nevertheless, some laboratories may prefer loading water into silver capsules because expensive equipment is not needed, but they are cautioned to apply the necessary corrections for evaporation, back exchange with laboratory atmospheric moisture, and blank.","language":"English","publisher":"Wiley","publisherLocation":"Hoboken, NJ","doi":"10.1002/rcm.4559","usgsCitation":"Qi, H., Groning, M., Coplen, T.B., Buck, B., Mroczkowski, S.J., Brand, W., Geilmann, H., and Gehre, M., 2010, Novel silver tubing method for quantitative introduction of water into high temperature conversion systems for stable hydrogen and oxygen isotopic measurements: Rapid Communications in Mass Spectrometry, v. 24, no. 13, p. 1821-1827, https://doi.org/10.1002/rcm.4559.","productDescription":"7 p.","startPage":"1821","endPage":"1827","numberOfPages":"7","additionalOnlineFiles":"N","ipdsId":"IP-020156","costCenters":[{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true},{"id":588,"text":"Toxic Hydrology Program","active":false,"usgs":true}],"links":[{"id":269701,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":269698,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/rcm.4559"}],"volume":"24","issue":"13","noUsgsAuthors":false,"publicationDate":"2010-06-02","publicationStatus":"PW","scienceBaseUri":"514988f2e4b0971933f6369f","contributors":{"authors":[{"text":"Qi, Haiping 0000-0002-8339-744X haipingq@usgs.gov","orcid":"https://orcid.org/0000-0002-8339-744X","contributorId":507,"corporation":false,"usgs":true,"family":"Qi","given":"Haiping","email":"haipingq@usgs.gov","affiliations":[{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true}],"preferred":true,"id":475775,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Groning, Manfred","contributorId":47659,"corporation":false,"usgs":true,"family":"Groning","given":"Manfred","affiliations":[],"preferred":false,"id":475782,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Coplen, Tyler B. 0000-0003-4884-6008 tbcoplen@usgs.gov","orcid":"https://orcid.org/0000-0003-4884-6008","contributorId":508,"corporation":false,"usgs":true,"family":"Coplen","given":"Tyler","email":"tbcoplen@usgs.gov","middleInitial":"B.","affiliations":[{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true},{"id":27111,"text":"National Water Quality Program","active":true,"usgs":true},{"id":37464,"text":"WMA - Laboratory & Analytical Services Division","active":true,"usgs":true},{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true}],"preferred":true,"id":475776,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Buck, Bryan bbuck@usgs.gov","contributorId":2326,"corporation":false,"usgs":true,"family":"Buck","given":"Bryan","email":"bbuck@usgs.gov","affiliations":[{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true}],"preferred":true,"id":475777,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Mroczkowski, Stanley J. 0000-0001-8026-6025 smroczko@usgs.gov","orcid":"https://orcid.org/0000-0001-8026-6025","contributorId":2628,"corporation":false,"usgs":true,"family":"Mroczkowski","given":"Stanley","email":"smroczko@usgs.gov","middleInitial":"J.","affiliations":[{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true}],"preferred":true,"id":475778,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Brand, Willi A.","contributorId":38866,"corporation":false,"usgs":true,"family":"Brand","given":"Willi A.","affiliations":[],"preferred":false,"id":475780,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Geilmann, Heike","contributorId":41303,"corporation":false,"usgs":false,"family":"Geilmann","given":"Heike","email":"","affiliations":[{"id":13365,"text":"Max-Planck Institute for Biogeochemistry, Jena, Germany","active":true,"usgs":false}],"preferred":false,"id":475781,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Gehre, Matthias","contributorId":34004,"corporation":false,"usgs":false,"family":"Gehre","given":"Matthias","email":"","affiliations":[],"preferred":false,"id":475779,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

The TSWs were located in spill bays 4 and 20 during spring and in spill bays 19 and 20 during summer. Our objectives were to assess the performance of the TSWs as a fish passage alternative. We also examined how tailrace conditions might have influenced fish survival by releasing drift buoys (drogues).\nThe TSWs proved to be a relatively effective way to pass juvenile salmonids at McNary Dam (Summary Tables 1.1, 1.2, and 1.3), as was the case in 2007 and 2008. The TSWs passed about 14% of yearling Chinook salmon and 34% of juvenile steelhead with only 5-10% of total project discharge flowing through the TSWs. The TSWs and adjacent spill bays 16-18 passed 27% of subyearling Chinook salmon in the summer with 6-16% of total project discharge flowing through the TSWs. Based on the number of fish passing per the proportion of water flowing through the spillway (i.e., passage effectiveness), the TSWs were the most effective passage route. Passage effectiveness for fish passing through both TSW structures was 2.0 for yearling Chinook salmon, 5.2 for juvenile steelhead, and 2.7 subyearling Chinook salmon for TSW 20 alone. Higher passage of juvenile steelhead through the TSWs could have resulted from juvenile steelhead being more surface-oriented during migration (Plumb et al. 2004; Beeman et al. 2007; Beeman and Maule 2006). Based on passage performance and effectiveness metrics, TSW 4, located on the north end of the spillway, did not perform as well as TSW 20, located on the south end of the spillway. Passage proportions for TSW 4 were at least half that of the levels observed for TSW 20 for both yearling Chinook salmon and juvenile steelhead.

The middle part of the bed is a mineralized bacterial mat (quartz, goethite). Textures resembling bacterial cells and colonies are common, with wavy, bulbous laminations composed of mounds overlying a mesh-work stromatolite-like texture constructed of micrometre-size Fe oxides. This bed is concordant with the underlying Mn deposit and marks the termination of Mn accumulation. Although no genetic connection exists between the two, the rocks adjacent to the contact record the oceanographic and bottom-water conditions extant when accumulation of one of the major Mn deposits of Europe ended, when the Transdanubian Range was located in the middle of the Adria-Apulian microcontinent between the Neotethys and Atlantic-Ligurian seaways.

This study used physical and chemical water quality and stable nitrogen isotope (δ<sup>15</sup>N) measurements from zooplankton to examine nitrogen (N) sources and concentrations in four small lakes of Khorezm, Uzbekistan, an arid, highly agricultural region, which is part of the environmentally-impacted Aral Sea Basin. During the 2-year study period, ammonium concentrations were the highest dissolved inorganic N species in all lakes, with a maximum of 3.00 mg N l<sup>−1</sup> and an average concentration of 0.62 mg N l<sup>−1</sup>. Nitrate levels were low, with a maximum concentration of 0.46 mg N l<sup>−1</sup> and an average of 0.05 mg N l<sup>−1</sup> for all four lakes. The limited zooplankton δ<sup>15</sup>N values did not correlate with the high loads of synthetic fertilizer applied to local croplands during summer months. These results suggest that the N cycles in these lakes may be more influenced by regional dynamics than agricultural activity in the immediate surroundings.

During the developmental phase of the pump station, a need was identified to better understand the larval drift characteristics of these endangered catostomids in order to reduce entrainment into the irrigation system. The spatial, seasonal, and diel distribution of drifting larvae was measured during the 2004 spawning season at two proposed sites on the Williamson River where the pump station could be located. Larval drift for both species coincided with the irrigation season making them subject to entrainment into the irrigation system. Drift occurred almost exclusively at night with larvae entering the drift at sunset and exiting the drift at sunrise. Nighttime larval densities were concentrated near the surface and at midchannel at both sites. Densities were generally greater on the side of mid-channel with greater flow. During early morning sampling we detected a general shift in larval drift from surface to subsurface drift. We also observed an increase in larval densities towards the shore opposite from the proposed pump station at the upper site whereas larval densities remained high at midchannel at the lower site. During daytime sampling, the few larvae that were collected were distributed throughout the water column at both pump sites. This study found that larvae drifting during all time periods were generally distributed further across the cross section, deeper in the water column, and closer to where the proposed water withdrawal structure would be built at the downstream site when compared to the upstream site. Recommendations were provided to locate the withdrawal facility at the upstream site and operate it in a manner such that larval entrainment would likely be minimized.","language":"English","publisher":"Springer","doi":"10.1007/s10641-010-9688-8","usgsCitation":"Ellsworth, C.M., Tyler, T.J., and VanderKooi, S., 2010, Using spatial, seasonal, and diel drift patterns of larval Lost River suckers Deltistes luxatus (Cypriniformes: Catostomidae) and shortnose suckers Chasmistes brevirostris (Cypriniformes: Catostomidae) to help identify a site for a water withdrawal structure on the Williamson River, Oregon: Environmental Biology of Fishes, v. 89, no. 1, p. 47-57, https://doi.org/10.1007/s10641-010-9688-8.","productDescription":"11 p.","startPage":"47","endPage":"57","ipdsId":"IP-015357","costCenters":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"links":[{"id":272295,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":272294,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10641-010-9688-8"}],"country":"United States","state":"Oregon","otherGeospatial":"Williamson River","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -12.018333333333334,4.035833333333334 ], [ -12.018333333333334,0.0011111111111111111 ], [ -12.018333333333334,0.0011111111111111111 ], [ -12.018333333333334,4.035833333333334 ], [ -12.018333333333334,4.035833333333334 ] ] ] } } ] }","volume":"89","issue":"1","noUsgsAuthors":false,"publicationDate":"2010-08-03","publicationStatus":"PW","scienceBaseUri":"51955850e4b0a933d82c4ccb","contributors":{"authors":[{"text":"Ellsworth, Craig M.","contributorId":14913,"corporation":false,"usgs":true,"family":"Ellsworth","given":"Craig","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":474037,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Tyler, Torrey J.","contributorId":91199,"corporation":false,"usgs":true,"family":"Tyler","given":"Torrey","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":474038,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"VanderKooi, Scott P.","contributorId":106584,"corporation":false,"usgs":true,"family":"VanderKooi","given":"Scott P.","affiliations":[],"preferred":false,"id":474039,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

During re-wetting of the watershed in late September and early October of 2001, increasing stream flows were accompanied by decreasing Na<sup>+</sup> and Ca<sup>2+</sup> concentrations, but SO<sub>4</sub><sup>2 -</sup> concentrations continued to increase up to 568 ??eq/L, indicating that a major source of SO<sub>4</sub><sup>2 -</sup> in addition to bedrock weathering contributed to peak SO<sub>4</sub><sup>2 -</sup> concentrations. The further increase in SO<sub>4</sub><sup>2 -</sup> concentrations coincided with an abrupt decrease of ??<sup>34</sup>S values in stream water SO<sub>4</sub><sup>2 -</sup> from maximum values near +10??? to minimum values near -3???. Soil investigations revealed that some C-horizons in the Spodsols of the watershed contained secondary sulfide minerals with ??<sup>34</sup>S values near -22???. The shift to negative ??<sup>34</sup>S values of stream water SO<sub>4</sub><sup>2 -</sup> indicates that secondary sulfides in C-horizons were oxidized to SO<sub>4</sub><sup>2 -</sup> during the particularly dry summer of 2001. The newly formed SO<sub>4</sub><sup>2 -</sup> was transported to the streams during re-wetting of the watershed contributing ???60% of the SO<sub>4</sub><sup>2 -</sup> during peak concentrations in the stream water. Thereafter, the contribution of SO<sub>4</sub><sup>2 -</sup> from oxidation of secondary sulfides in C-horizons decreased rapidly and pedogenic SO<sub>4</sub><sup>2 -</sup> reemerged as a dominant SO<sub>4</sub><sup>2 -</sup> source in concert with decreasing SO<sub>4</sub><sup>2 -</sup> concentrations in spring of 2002. The study provides evidence that a quantitative assessment of the sources of stream water SO<sub>4</sub><sup>2 -</sup> in forested watersheds is possible by combining hydrological, chemical and isotopic techniques, provided that the isotopic compositions of all potential SO<sub>4</sub><sup>2 -</sup> sources are distinctly different. ?? 2010 Elsevier Ltd.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Applied Geochemistry","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.apgeochem.2010.02.007","issn":"08832927","usgsCitation":"Mayer, B., Shanley, J.B., Bailey, S., and Mitchell, M., 2010, Identifying sources of stream water sulfate after a summer drought in the Sleepers River watershed (Vermont, USA) using hydrological, chemical, and isotopic techniques: Applied Geochemistry, v. 25, no. 5, p. 747-754, https://doi.org/10.1016/j.apgeochem.2010.02.007.","startPage":"747","endPage":"754","numberOfPages":"8","costCenters":[],"links":[{"id":217371,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.apgeochem.2010.02.007"},{"id":245316,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"25","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a3857e4b0c8380cd6152e","contributors":{"authors":[{"text":"Mayer, B.","contributorId":84538,"corporation":false,"usgs":true,"family":"Mayer","given":"B.","email":"","affiliations":[],"preferred":false,"id":460123,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Shanley, J.

The methods included frequency‐domain electromagnetics (FDEM), ground‐penetrating radar (GPR), electrical resistivity tomography (ERT), and multi‐channel analysis of surface‐wave (MASW) seismic. The results of each method were compared to each other and to drive‐point data from the site. FDEM was used as a reconnaissance method to assess buried utilities and anthropogenic structures; to identify near‐surface changes in water chemistry related to conductive leachate from road‐salt storage; and to investigate a resistive signature possibly caused by groundwater discharge. Shallow anomalies observed in the GPR and ERT data were caused by near‐surface infrastructure and were consistent with anomalies observed in the FDEM data. Several parabolic reflectors were observed in the upper part of the GPR profiles, and a fairly continuous reflector that was interpreted as bedrock could be traced across the lower part of the profiles. MASW seismic data showed a sharp break in shear wave velocity at depth, which was interpreted as the overburden/bedrock interface. The MASW profile indicates the presence of a trough in the bedrock surface in the same location where the ERT data indicate lateral variations in resistivity. Depths to bedrock interpreted from the ERT, MASW, and GPR profiles were similar and consistent with the depths of refusal identified in the direct‐push wells. The interpretations of data collected using the individual methods yielded non‐unique solutions with considerable uncertainty. Integrated interpretation of the electrical, electromagnetic, and seismic geophysical profiles produced a more consistent and unique estimation of depth to bedrock that is consistent with ground‐truth data at the site. This test case shows that using complementary techniques that measure different properties can be more effective for site characterization than a single‐method investigation.</span><span></span></p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Symposium on the Application of Geophysics to Engineering and Environmental Problems 2010","largerWorkSubtype":{"id":12,"text":"Conference publication"},"language":"English","publisher":"Society of Exploration Geophysicists","doi":"10.4133/1.3445441","usgsCitation":"Johnson, C.D., Lane, J.W., Brandon, W.C., Williams, C.A., and White, E.A., 2010, Integrated use of surface geophysical methods for site characterization — A case study in North Kingstown, Rhode Island, <i>in</i> Symposium on the Application of Geophysics to Engineering and Environmental Problems 2010, p. 253-263, https://doi.org/10.4133/1.3445441.","productDescription":"11 p.","startPage":"253","endPage":"263","ipdsId":"IP-019287","costCenters":[{"id":486,"text":"OGW Branch of Geophysics","active":true,"usgs":true},{"id":493,"text":"Office of Ground Water","active":true,"usgs":true}],"links":[{"id":350795,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Rhode Island","city":"North Kingstown","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -71.58176422119139,\n              41.48697733905992\n            ],\n            [\n              -71.40666961669922,\n              41.48697733905992\n            ],\n            [\n              -71.40666961669922,\n              41.64136125487125\n            ],\n            [\n              -71.58176422119139,\n              41.64136125487125\n            ],\n            [\n              -71.58176422119139,\n              41.48697733905992\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","publishingServiceCenter":{"id":11,"text":"Pembroke PSC"},"noUsgsAuthors":false,"publicationDate":"2010-05-17","publicationStatus":"PW","scienceBaseUri":"5a719271e4b0a9a2e9dbde25","contributors":{"authors":[{"text":"Johnson, Carole D. 0000-0001-6941-1578 cjohnson@usgs.gov","orcid":"https://orcid.org/0000-0001-6941-1578","contributorId":1891,"corporation":false,"usgs":true,"family":"Johnson","given":"Carole","email":"cjohnson@usgs.gov","middleInitial":"D.","affiliations":[{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true}],"preferred":true,"id":720275,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lane, John W.

Reproducing populations of&nbsp;<i>L. rimosus</i>&nbsp;now occur only in the Clinch, Duck and Powell rivers, as the species is considered extirpated from the remaining portions of its range in the Tennessee River drainage. Females are long-term winter brooders, typically gravid from Oct. to May. Glochidia are contained in the outer gills and are released in association with a mantle-lure that resembles a small freshwater snail. Estimated fecundity, based on 8 gravid females collected from the Clinch and Duck rivers, ranged from 4132 to 58,700 glochidia/mussel. Seven fish species were tested for suitability as hosts for glochidia, and five darter species were confirmed through induced infestations:&nbsp;<i>Etheostoma blennioides</i>,&nbsp;<i>E. camurum</i>,&nbsp;<i>E. rufilineatum</i>,&nbsp;<i>E. simoterum</i>&nbsp;and&nbsp;<i>E. zonale</i>. Ages of&nbsp;<i>L. rimosus</i>&nbsp;shells were determined by thin-sectioning and ranged from 3 to 15&nbsp;y in both rivers. Shell growth was higher and maximum size greater in males than females in both rivers. Shell growth was greatest in the Duck River.

It is useful for unsaturated flow processes that are not inherently diffusive, or that do not progress through a series of equilibrium states. The term source-responsive is used to mean that flow responds sensitively to changing conditions at the source of water input (e.g., rainfall, irrigation, or ponded infiltration). The domain of preferential flow can be conceptualized as laminar flow in free-surface films along the walls of pores. These films may be considered to have uniform thickness, as suggested by field evidence that preferential flow moves at an approximately uniform rate when generated by a continuous and ample water supply. An effective facial area per unit volume quantitatively characterizes the medium with respect to source-responsive flow. A flow-intensity factor dependent on conditions within the medium represents the amount of source-responsive flow at a given time and position. Laminar flow theory provides relations for the velocity and thickness of flowing source-responsive films. Combination with the Darcy-Buckingham law and the continuity equation leads to expressions for both fluxes and dynamic water contents. Where preferential flow is sometimes or always significant, the interactive combination of source-responsive and diffuse flow has the potential to improve prediction of unsaturated-zone fluxes in response to hydraulic inputs and the evolving distribution of soil moisture. Examples for which this approach is efficient and physically plausible include (i) rainstorm-generated rapid fluctuations of a deep water table and (ii) space- and time-dependent soil water content response to infiltration in a macroporous soil. ??

The goal of this field-monitoring project was to assess how and under what circumstances nitrogen (N) nutrients under cultivated corn that is irrigated with this treated wastewater can reach the deep ground water of the underlying High Plains aquifer, and what can realistically be done to minimize this problem. We collected 15.2-m-deep cores for physical and chemical properties characterization; installed neutron moisture-probe access tubes and suction lysimeters for periodic measurements; sampled area monitoring, irrigation, and domestic wells; performed dye-tracer experiments to examine soil preferential-flow processes through macropores; and obtained climatic, crop, irrigation, and N-application rate records. These data and additional information were used in the comprehensive Root Zone Water Quality Model (RZWQM2) to identify key parameters and processes that influence N losses in the study area. We demonstrated that nitrate-N transport processes result in significant accumulations of N in the thick vadose zone. We also showed that nitrate-N in the underlying ground water is increasing with time and that the source of the nitrate is from the wastewater applications. RZWQM2 simulations indicated that macropore flow is generated particularly during heavy rainfall events, but during our 2005-06 simulations the total macropore flow was only about 3% of precipitation for one of two investigated sites, whereas it was more than 13% for the other site. Our calibrated model for the two wastewater-irrigated study sites indicated that reducing current levels of corn N fertilization by half or more to the level of 170 kg/ha substantially increases N-use efficiency and achieves near-maximum crop yield. Combining such measures with a crop rotation that includes alfalfa should further reduce the amounts of residual N in the soil, as indicated in one of the study sites that had alfalfa in past crop rotations.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Current Research in Earth Sciences","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","usgsCitation":"Sophocleous, M., Townsend, M., Vocasek, F., Ma, L., and Ashok, K., 2010, Treated wastewater and Nitrate transport beneath irrigated fields near Dodge city, Kansas: Current Research in Earth Sciences, v. 258, no. 1, p. 1-31.","startPage":"1","endPage":"31","numberOfPages":"31","costCenters":[],"links":[{"id":241565,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"258","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bb78fe4b08c986b32734e","contributors":{"authors":[{"text":"Sophocleous, M.","contributorId":13373,"corporation":false,"usgs":true,"family":"Sophocleous","given":"M.","email":"","affiliations":[],"preferred":false,"id":437507,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Townsend, M.A.","contributorId":88785,"corporation":false,"usgs":true,"family":"Townsend","given":"M.A.","email":"","affiliations":[],"preferred":false,"id":437511,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Vocasek, F.","contributorId":51996,"corporation":false,"usgs":true,"family":"Vocasek","given":"F.","email":"","affiliations":[],"preferred":false,"id":437509,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Ma, Liwang","contributorId":29140,"corporation":false,"usgs":true,"family":"Ma","given":"Liwang","email":"","affiliations":[],"preferred":false,"id":437508,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Ashok, K.C.","contributorId":56867,"corporation":false,"usgs":true,"family":"Ashok","given":"K.C.","email":"","affiliations":[],"preferred":false,"id":437510,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Lysimeters are often used to quantify the groundwater evaporation contribution influenced by a broad range of environmental factors. However, it is difficult for such field facilities, which are operated under limited conditions within limited time, to capture the whole spectrum of capillary upflow with regard to the inter-seasonal variability of climate, especially rainfall. Therefore, in this work, the method of combining lysimeter and numerical experiments was implemented to investigate seasonal groundwater contribution to crop-water use. Groundwater evaporation experiments were conducted through a weighing lysimeter at an agricultural experiment station located within an irrigation district in the lower Yellow River Basin for two winter wheat growth seasons. A HYDRUS-1D model was first calibrated and validated with weighing lysimeter data, and then was employed to perform scenario simulations of groundwater evaporation under different depths to water table (DTW) and water input (rainfall plus irrigation) driven by long term meteorological data. The scenario simulations revealed that the seasonally averaged groundwater evaporation amount was linearly correlated to water input for different values of DTW. The linear regression could explain more than 70% of the variability. The seasonally averaged ratio of the groundwater contribution to crop-water use varied with the seasonal water input and DTW. The ratio reached as high as 75% in the case of DTW=1.0. m and no irrigation, and as low as 3% in the case of DTW=3.0. m and three irrigation applications. The results also revealed that the ratio of seasonal groundwater evaporation to potential evapotranspiration could be fitted to an exponential function of the DTW that may be applied to estimate seasonal groundwater evaporation. In this case study of multilayered soil profile, the depth at which groundwater may evaporate at potential rate was 0.60-0.65. m, and the extinction depth of groundwater evaporation was approximately 3.8. m. ?? 2010 Elsevier B.V.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Hydrology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.jhydrol.2010.06.011","issn":"00221694","usgsCitation":"Luo, Y., and Sophocleous, M., 2010, Seasonal groundwater contribution to crop-water use assessed with lysimeter observations and model simulations: Journal of Hydrology, v. 389, no. 3-4, p. 325-335, https://doi.org/10.1016/j.jhydrol.2010.06.011.","startPage":"325","endPage":"335","numberOfPages":"11","costCenters":[],"links":[{"id":213638,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.jhydrol.2010.06.011"},{"id":241284,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"389","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b88aae4b08c986b316ab9","contributors":{"authors":[{"text":"Luo, Y.","contributorId":28417,"corporation":false,"usgs":true,"family":"Luo","given":"Y.","email":"","affiliations":[],"preferred":false,"id":436902,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sophocleous, M.","contributorId":13373,"corporation":false,"usgs":true,"family":"Sophocleous","given":"M.","email":"","affiliations":[],"preferred":false,"id":436901,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

This creates a complex gradient that influences species composition of macrophyte communities from lake to lake.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.aquabot.2010.02.001","issn":"03043770","usgsCitation":"Sass, L.L., Bozek, M.A., Hauxwell, J.A., Wagner, K., and Knight, S., 2010, Response of aquatic macrophytes to human land use perturbations in the watersheds of Wisconsin lakes, U.S.A.: Aquatic Botany, v. 93, no. 1, p. 1-8, https://doi.org/10.1016/j.aquabot.2010.02.001.","productDescription":"8 p.","startPage":"1","endPage":"8","numberOfPages":"8","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-014144","costCenters":[{"id":199,"text":"Coop Res Unit Leetown","active":true,"usgs":true}],"links":[{"id":244901,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":216994,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.aquabot.2010.02.001"}],"country":"United States","state":"Wisconsin","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -87.978515625,\n              42.49235259142821\n            ],\n            [\n              -89.82421875,\n              42.512601715736665\n            ],\n            [\n              -89.8681640625,\n              43.06086137134326\n            ],\n            [\n              -89.593505859375,\n              43.42898792344155\n            ],\n            [\n              -92.274169921875,\n              45.62940492064501\n            ],\n            [\n              -92.296142578125,\n              46.36967413462374\n            ],\n            [\n              -90.0714111328125,\n              46.33555079758302\n            ],\n            [\n              -89.0716552734375,\n              46.145588688591964\n            ],\n            [\n              -88.802490234375,\n              46.01985337287631\n            ],\n            [\n              -88.5333251953125,\n              44.44554600843545\n            ],\n            [\n              -87.528076171875,\n              44.201897151875094\n            ],\n            [\n              -87.659912109375,\n              44.09942068528651\n            ],\n            [\n              -87.747802734375,\n              43.878097874251736\n            ],\n            [\n              -88.0389404296875,\n              42.88803956056295\n            ],\n            [\n              -87.978515625,\n              42.49235259142821\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"93","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505aaa30e4b0c8380cd861c5","contributors":{"authors":[{"text":"Sass, Laura L.","contributorId":38813,"corporation":false,"usgs":false,"family":"Sass","given":"Laura","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":459713,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bozek, Michael A.","contributorId":51030,"corporation":false,"usgs":true,"family":"Bozek","given":"Michael","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":459716,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hauxwell, Jennifer A.","contributorId":53628,"corporation":false,"usgs":false,"family":"Hauxwell","given":"Jennifer","email":"","middleInitial":"A.","affiliations":[{"id":7242,"text":"Wisconsin Department of Natural Resources, Madison, WI, USA","active":true,"usgs":false}],"preferred":false,"id":459717,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Wagner, Kelly","contributorId":45930,"corporation":false,"usgs":false,"family":"Wagner","given":"Kelly","email":"","affiliations":[{"id":7242,"text":"Wisconsin Department of Natural Resources, Madison, WI, USA","active":true,"usgs":false}],"preferred":false,"id":459715,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Knight, Susan","contributorId":44010,"corporation":false,"usgs":false,"family":"Knight","given":"Susan","affiliations":[{"id":7191,"text":"Trout Lake Station, Center for Limnology, University of Wisconsin-Madison, Boulder Junction, WI, USA","active":true,"usgs":false}],"preferred":false,"id":459714,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Using an iterative process, the model was simplified to a single measurement (head-to-bill length) that still assigned sex correctly 94% of the time. A previous California Gull sex determination model developed for a population in Wyoming was then assessed by fitting SFB California Gull measurement data to the Wyoming model; this new model failed to converge on the same measurements as those originally used by the Wyoming model. Results from the SFB discriminant function model were compared to the Wyoming model results (by using SFB data with the Wyoming model); the SFB model was 7% more accurate for SFB California gulls.

Ratios of maximum to minimum mean daily discharge and average recession indices are calculated for watersheds within and surrounding the Yellowstone volcanic plateau. A model for snowmelt recession is used to separate groundwater discharge from overland runoff, and compare groundwater systems. Hydrograph signal interpretation is corroborated with chlorofluorocarbon (CFC) and tritium concentrations in cool water springs on the Yellowstone volcanic plateau. Hydrograph parameters show a spatial pattern correlated with watershed geology. Watersheds comprised dominantly of quaternary Yellowstone volcanics are characterized by slow streamflow recession, low maximum to minimum flow ratios. Cool springs sampled within the Park contain CFC's and tritium and have apparent CFC age dates that range from about 50 years to modern. Watersheds comprised of quaternary Yellowstone volcanics have a large volume of active groundwater circulation. A large, advecting groundwater field would be the dominant mechanism for mass and energy transport in the shallow crust of the Yellowstone volcanic plateau, and thus control the Yellowstone hydrothermal system. ?? 2009 Elsevier B.V.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Hydrology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.jhydrol.2009.12.037","issn":"00221694","usgsCitation":"Payton, G., Susong, D., Kip, S.D., and Heasler, H., 2010, Snowmelt hydrograph interpretation: Revealing watershed scale hydrologic characteristics of the Yellowstone volcanic plateau: Journal of Hydrology, v. 383, no. 3-4, p. 209-222, https://doi.org/10.1016/j.jhydrol.2009.12.037.","startPage":"209","endPage":"222","numberOfPages":"14","costCenters":[],"links":[{"id":245353,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":217407,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.jhydrol.2009.12.037"}],"volume":"383","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b91b8e4b08c986b319a67","contributors":{"authors":[{"text":"Payton, Gardner W.","contributorId":87395,"corporation":false,"usgs":true,"family":"Payton","given":"Gardner W.","affiliations":[],"preferred":false,"id":460474,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Susong, D.
