Water column, sediment, and pore water concentrations of methylmercury (MeHg) and total mercury (THg), as well as related aquatic chemical parameters were examined. Inorganic Hg(II)-methylation rates were determined in selected water column and sediment subsamples spiked with inorganic divalent mercury (</span><sup>204</sup><span>Hg(II)).

Notable findings include: 1) elevated Hg concentrations previously reported in birds and brine flies were spatially proximal to the measured highest MeHg concentrations, the latter occurring in the anoxic deep brine layer (DBL) of the Great Salt Lake; 2) timing of reduced Hg(II)-methylation rates in the DBL (according to both<span>&nbsp;</span></span><i>k<sub>meth</sub></i><span><span>&nbsp;</span>and MPP) coincides with reduced Hg burdens among aquatic invertebrates (brine shrimp and brine flies) that act as potential vectors of Hg propagation to the terrestrial ecosystem; 3) values of</span><i>k<sub>meth</sub></i><span><span>&nbsp;</span>were found to fall within the range reported by other studies; and 4) MPP rates were on the lower end of the range reported in methodologically comparable studies, suggesting the possibility that elevated MeHg in the anoxic deep brine layer results from its accumulation and persistence in this quasi-isolated environment, due to the absence of light (restricting abiotic photo demethylation) and/or minimal microbiological demethylation.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.scitotenv.2014.12.092","usgsCitation":"Johnson, W.P., Swanson, N., Black, B., Rudd, A., Carling, G., Fernandez, D.P., Luft, J., Van Leeuwen, J., and Marvin-DiPasquale, M.C., 2015, Total- and methyl-mercury concentrations and methylation rates across the freshwater to hypersaline continuum of the Great Salt Lake, Utah, USA: Science of the Total Environment, v. 511, p. 489-500, https://doi.org/10.1016/j.scitotenv.2014.12.092.","productDescription":"12 p.","startPage":"489","endPage":"500","numberOfPages":"12","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-062111","costCenters":[{"id":438,"text":"National Research Program -

To investigate causes and effects of mobility, we focus on a disastrous landslide that occurred on 22 March 2014 near Oso, Washington, USA, following a long period of abnormally wet weather.

Seismological evidence indicates that high-speed, flowing motion of the landslide began after about 50 s of preliminary slope movement, and observational evidence supports the hypothesis that the high mobility of the landslide resulted from liquefaction of water-saturated sediment at its base. Numerical simulation of the event using a newly developed model indicates that liquefaction and high mobility can be attributed to compression- and/or shear-induced sediment contraction that was strongly dependent on initial conditions. An alternative numerical simulation indicates that the landslide would have been far less mobile if its initial porosity and water content had been only slightly lower. Sensitive dependence of landslide mobility on initial conditions has broad implications for assessment of landslide hazards.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.epsl.2014.12.020","usgsCitation":"Iverson, R.M., George, D.L., Allstadt, K., Reid, M.E., Collins, B.D., Vallance,

Sap flow, evaporative losses and soil moisture measurements were used to determine transpiration, evapotranspiration and plant-available soil water before and after flooding. A formula was developed using plant-available soil water post-flooding and average annual rainfall, to estimate maintenance time of soil water reserves in each flood frequency zone. Results indicated that soil water reserves could sustain 1:2 and 1:5 trees for 15 months and six years, respectively.

Abrupt transitions in surface lithology exist along the main-stem channel course. Both of these characteristics afford an opportunity to examine hydrologic, lithologic, and sedimentary controls on downstream changes in channel morphology. Field surveys of channel topography and boundary composition are coupled with sediment analyses, hydraulic computations, flood-frequency analyses, and geographic information system mapping to discern controls on channel geometry (profile, pattern, and shape) and dimensions along the mixed alluvial-bedrock Llano River and key tributaries. Four categories of channel classification in a downstream direction include: (i) uppermost ephemeral reaches, (ii) straight or sinuous gravel-bed channels in Cretaceous carbonate sedimentary zones, (iii) straight or sinuous gravel-bed or bedrock channels in Paleozoic sedimentary zones, and (iv) straight, braided, or multithread mixed alluvial&ndash;bedrock channels with sandy beds in Precambrian igneous and metamorphic zones. Principal findings include: (i) a nearly linear channel profile attributed to resistant bedrock incision checkpoints; (ii) statistically significant correlations of both alluvial sinuosity and valley confinement to relatively high f (mean depth) hydraulic geometry values; (iii) relatively high b (width) hydraulic geometry values in partly confined settings with sinuous channels upstream from a prominent incision checkpoint; (iv) different functional flow categories including frequently occurring events (&lt; 1.5-year return periods) that mobilize channel-bed material and less frequent events that determine bankfull channel (1.5- to 3-year return periods) and macrochannel (10- to 40-year return periods) dimensions; (v) macrochannels with high f values (most &le; 0.45) that develop at sites with unit stream power values in excess of 200 watts per square meter (W/m2); and (vi) downstream convergence of hydraulic geometry exponents for bankfull and macrochannels, explained by co-increases of flood magnitude and noncohesive sandy sediments that collectively minimize development of alluvial bankfull indicators. Collectively, these findings indicate that mixed alluvial&ndash;bedrock channels exhibit first-order lithologic controls (lithologic resistance and valley confinement) of channel geometry, second-order hydrologic (flow regime) control of channel dimensions, and third-order sedimentary controls that exert subsidiary influence on channel shape and bed configuration.</p>","language":"English","publisher":"Elsevier Science","publisherLocation":"New York, NY","doi":"10.1016/j.geomorph.2014.12.033","usgsCitation":"Heitmuller, F.T., Hudson, P.F., and Asquith, W.H., 2015, Lithologic and hydrologic controls of mixed alluvial-bedrock channels in flood-prone fluvial systems: bankfull and macrochannels in the Llano River watershed, central Texas, USA: Geomorphology, v. 232, p. 1-19, https://doi.org/10.1016/j.geomorph.2014.12.033.","productDescription":"19 p.","startPage":"1","endPage":"19","numberOfPages":"19","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-059853","costCenters":[{"id":583,"text":"Texas Water Science Center","active":true,"usgs":true}],"links":[{"id":297224,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Texas","otherGeospatial":"Llano River Watershed","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -98.56658935546875,\n              30.36102635890718\n            ],\n            [\n              -98.56658935546875,\n              30.958768570779846\n            ],\n            [\n              -97.83050537109375,\n              30.958768570779846\n            ],\n            [\n              -97.83050537109375,\n              30.36102635890718\n            ],\n            [\n              -98.56658935546875,\n              30.36102635890718\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"232","publishingServiceCenter":{"id":5,"text":"Lafayette PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"54dd2a92e4b08de9379b3100","chorus":{"doi":"10.1016/j.geomorph.2014.12.033","url":"http://dx.doi.org/10.1016/j.geomorph.2014.12.033","publisher":"Elsevier BV","authors":"Heitmuller Franklin T., Hudson Paul F., Asquith William H.","journalName":"Geomorphology","publicationDate":"3/2015","auditedOn":"2/13/2015"},"contributors":{"authors":[{"text":"Heitmuller, Frank T.","contributorId":138602,"corporation":false,"usgs":false,"family":"Heitmuller","given":"Frank","email":"","middleInitial":"T.","affiliations":[{"id":12460,"text":"The University of Southern Mississippi","active":true,"usgs":false}],"preferred":false,"id":538025,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hudson, Paul F.","contributorId":138603,"corporation":false,"usgs":false,"family":"Hudson","given":"Paul","email":"","middleInitial":"F.","affiliations":[{"id":12461,"text":"Leiden University College The Hague","active":true,"usgs":false}],"preferred":false,"id":538026,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Asquith, William H. 0000-0002-7400-1861 wasquith@usgs.gov","orcid":"https://orcid.org/0000-0002-7400-1861","contributorId":1007,"corporation":false,"usgs":true,"family":"Asquith","given":"William","email":"wasquith@usgs.gov","middleInitial":"H.","affiliations":[{"id":48595,"text":"Oklahoma-Texas Water Science Center","active":true,"usgs":true}],"preferred":true,"id":538024,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Existing and future urbanization in the surrounding areas have the potential to affect water quality in the Park, and so the National Park Service and the U.S. Geological Survey designed a water-sampling strategy to document baseline conditions against which future changes can be compared. Sites in and near the Park were sampled twice, in July and December 2009, and included four anchialine pools, two large fishponds, five monitoring wells, an upland production well, tap water, and a holding pond for golf-course irrigation water. Water samples within the coastal park were brackish, ranging in salinity from 15 to 67 percent seawater. Samples were analyzed for dissolved inorganic nutrients (nitrogen and phosphorus), stable isotopes (nitrogen and oxygen in dissolved nitrate; hydrogen and oxygen in the water molecule), pharmaceuticals, wastewater compounds, and volatile organic compounds. A case of acute, but temporary, fertilizer contamination was evident along the Park's north boundary during the turf grow-in period of a newly constructed golf course. A maximum nitrogen concentration 280 percent above background level was measured in monitoring well MW401 in July, later falling to 109 percent above background by December. Two nearby sites (MW400 and AP 144) had nitrogen concentrations that were elevated compared to remaining sites but less severely than at MW401. Aside from this localized fertilizer influence, other water samples had lower nutrient enrichments: 40 percent or less above background for nitrogen and 57 percent or less above background for phosphorus. Background was defined in this study by a graphical mixing line between saltwater from a deep well in the Park and freshwater at a reference well in the mountainous uplands (Honokōhau production well, at 1,675 ft altitude). Potential nutrient sources between the uplands and coastal lowlands that could contribute to enrichment include rock weathering, natural vegetation, fertilizers, septic leachate, and atmospheric deposition &ndash; including motor-vehicle exhaust.</p>\n<p>Some fraction of septic leachate is expected in groundwater because there are unsewered suburban and commercial developments upslope from the Park that rely on cesspools and septic systems. However, stable isotopes of nitrate did not implicate septic-waste nitrogen (heavy &delta;<sup>15</sup>N values on the order of +10 per mil or greater). Instead, the heaviest &delta;<sup>15</sup>N values of +6 to +8 per mil were associated with the large fishponds, likely as a result of biotic cycling. Water samples with &delta;<sup>15</sup>N values of +3 to +5 per mil were still isotopically heavier than the upland groundwater value of +2 per mil and likely reflect addition of heavier nitrogen, possibly from septic sources, nitrogen-fixing vegetation, or vehicular exhaust. Pharmaceuticals, wastewater compounds, and volatile organic compounds indicated that if contamination is present, it appears to be at low, barely detectable, levels--at least as reflected by the results of this study. The most diagnostic indication of septic contamination was at monitoring well KAHO 2, closest to Kaloko Light Industrial Park, where three pharmaceuticals (carbamazepine, sulfamethoxazole, and thiobendazole) were detected at trace-level parts-per-trillion concentrations. A screening-level test for laundry fabric brighteners indicated positive detection at most sites; however, readings were quite low and if laundry graywater is present, it appears to be a small, dilute fraction. Because the weather was persistently dry throughout the study period, the USGS team was unable to conduct a wet-weather &ldquo;storm&rdquo; sampling. Wet-weather results are expected to differ from those reported here, though by how much remains unknown.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/sir20145158","collaboration":"Prepared in cooperation with the National Park Service","usgsCitation":"Hunt, C.D., 2015, Baseline water-quality sampling to infer nutrient and contaminant sources at Kaloko-Honokōhau National Historical Park, Island of Hawai‘i, 2009: U.S. Geological Survey Scientific Investigations Report 2014-5158, Report: vii, 52 p.; 2 Tables, https://doi.org/10.3133/sir20145158.","productDescription":"Report: vii, 52 p.; 2 Tables","numberOfPages":"64","onlineOnly":"Y","additionalOnlineFiles":"Y","ipdsId":"IP-029480","costCenters":[{"id":525,"text":"Pacific Islands Water Science Center","active":true,"usgs":true}],"links":[{"id":297214,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/sir20145158.gif"},{"id":297211,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/sir/2014/5158/downloads/sir2014-5158_report.pdf","text":"Report","size":"5.7 MB","linkFileType":{"id":1,"text":"pdf"},"description":"Report"},{"id":297212,"rank":3,"type":{"id":2,"text":"Additional Report Piece"},"url":"https://pubs.usgs.gov/sir/2014/5158/downloads/sir2014-5158_table3.xlsx","text":"Table 3","size":"48 kB","linkFileType":{"id":3,"text":"xlsx"},"description":"Table 3","linkHelpText":"Laboratory results and field measurements for water samples collected at Kaloko-Honokōhau National Historical Park, Island of Hawai‘i, July 23-28, 2009."},{"id":297213,"rank":4,"type":{"id":2,"text":"Additional Report Piece"},"url":"https://pubs.usgs.gov/sir/2014/5158/downloads/sir2014-5158_table4.xlsx","text":"Table 4","size":"46 kB","linkFileType":{"id":3,"text":"xlsx"},"description":"Table 4","linkHelpText":"Laboratory results and field measurements for water samples collected at Kaloko-Honokōhau National Historical Park, Island of Hawai‘i, November 30-December 2, 2009."},{"id":297210,"rank":1,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/sir/2014/5158/"}],"country":"United States","state":"Hawai‘i","otherGeospatial":"Kaloko-Honokōhau National Historical Park","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -156.06903076171875,\n              19.598606721590237\n            ],\n            [\n              -156.06903076171875,\n              19.73697619787738\n            ],\n            [\n              -155.94268798828125,\n              19.73697619787738\n            ],\n            [\n              -155.94268798828125,\n              19.598606721590237\n            ],\n            [\n              -156.06903076171875,\n              19.598606721590237\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"54dd2a58e4b08de9379b2ff7","contributors":{"authors":[{"text":"Hunt, Charles D.

Understanding the relative changes in subsurface fluid pressures is important for systems, such as Devil's Slide, where slope creep can be interrupted by episodic slip events. Surface mapping, exploratory core, tunnel excavation records, and dip meter data were leveraged to conceptualize the parameter space for three-dimensional (3D) Devil's Slide-like simulations. Field observations (i.e. seepage meter, water retention, and infiltration experiments; well records; and piezometric data) and groundwater flow simulation (i.e. one-dimensional vertical, transient, and variably saturated) were used to design the boundary conditions for 3D Devil's Slide-like problems. Twenty-four simulations of steady-state saturated subsurface flow were conducted in a concept-development mode.

Comprehensive, published, and publicly available information regarding the extent, location, and character of hydraulic fracturing in the United States is scarce. This national spatial and temporal analysis of data on nearly 1 million hydraulically fractured wells and 1.8 million fracturing treatment records from 1947 through 2010 (aggregated in Data Series 868) is used to identify hydraulic fracturing trends in drilling methods and use of proppants, treatment fluids, additives, and water in the United States. These trends are compared to the literature in an effort to establish a common understanding of the differences in drilling methods, treatment fluids, and chemical additives and of how the newer technology has affected the water use volumes and areal distribution of hydraulic fracturing. Historically, Texas has had the highest number of records of hydraulic fracturing treatments and associated wells in the United States documented in the datasets described herein. Water-intensive horizontal/directional drilling has also increased from 6 percent of new hydraulically fractured wells drilled in the United States in 2000 to 42 percent of new wells drilled in 2010. Increases in horizontal drilling also coincided with the emergence of water-based &ldquo;slick water&rdquo; fracturing fluids. As such, the most current hydraulic fracturing materials and methods are notably different from those used in previous decades and have contributed to the development of previously inaccessible unconventional oil and gas production target areas, namely in shale and tight-sand reservoirs.

The source of these solutes is unknown; however, an understanding of the geochemical sources and processes controlling their presence in groundwater in the Mud Lake area is needed to better understand the geochemical sources and processes controlling the water quality of groundwater at the Idaho National Laboratory. The geochemical sources and processes controlling the water quality of groundwater in the Mud Lake area were determined by investigating the geology, hydrology, land use, and groundwater geochemistry in the Mud Lake area, proposing sources for solutes, and testing the proposed sources through geochemical modeling with PHREEQC. Modeling indicated that sources of water to the eastern Snake River Plain aquifer were groundwater from the Beaverhead Mountains and the Camas Creek drainage basin; surface water from Medicine Lodge and Camas Creeks, Mud Lake, and irrigation water; and upward flow of geothermal water from beneath the aquifer. Mixing of groundwater with surface water or other groundwater occurred throughout the aquifer. Carbonate reactions, silicate weathering, and dissolution of evaporite minerals and fertilizer explain most of the changes in chemistry in the aquifer. Redox reactions, cation exchange, and evaporation were locally important. The source of large concentrations of chloride, sodium, sulfate, and calcium was evaporite deposits in the unsaturated zone associated with Pleistocene Lake Terreton. Large amounts of chloride, sodium, sulfate, and calcium are added to groundwater from irrigation water infiltrating through lake bed sediments containing evaporite deposits and the resultant dissolution of gypsum, halite, sylvite, and bischofite.</span></p>","language":"English","publisher":"Springer","doi":"10.1007/s12665-014-3988-9","usgsCitation":"Rattray, G.W., 2015, Geochemical evolution of groundwater in the Mud Lake area, eastern Idaho, USA: Environmental Earth Sciences, v. 73, no. 12, p. 8251-8269, https://doi.org/10.1007/s12665-014-3988-9.","productDescription":"19 p.","startPage":"8251","endPage":"8269","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-054801","costCenters":[{"id":343,"text":"Idaho Water Science Center","active":true,"usgs":true}],"links":[{"id":472341,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1007/s12665-014-3988-9","text":"Publisher Index Page"},{"id":297528,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Idaho","otherGeospatial":"Mud Lake","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -117.09228515624999,\n              49.009050809382046\n            ],\n            [\n              -117.158203125,\n              42.04929263868686\n            ],\n            [\n              -111.005859375,\n              42.01665183556825\n            ],\n            [\n              -111.11572265625,\n              44.77793589631623\n            ],\n            [\n              -116.08154296875001,\n              48.99463598353408\n            ],\n            [\n              -117.09228515624999,\n              49.009050809382046\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"73","issue":"12","publishingServiceCenter":{"id":12,"text":"Tacoma PSC"},"noUsgsAuthors":false,"publicationDate":"2015-01-10","publicationStatus":"PW","scienceBaseUri":"54dd2a7de4b08de9379b30a4","contributors":{"authors":[{"text":"Rattray, Gordon W. 0000-0002-1690-3218 grattray@usgs.gov","orcid":"https://orcid.org/0000-0002-1690-3218","contributorId":2521,"corporation":false,"usgs":true,"family":"Rattray","given":"Gordon","email":"grattray@usgs.gov","middleInitial":"W.","affiliations":[{"id":343,"text":"Idaho Water Science Center","active":true,"usgs":true}],"preferred":true,"id":537579,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The program has been successful in reducing long-standing contentiousness in the regulatory process, while integrating science and policy in a coherent, rigorous, and transparent fashion. After 20 years, much has been learned about the relationship among waterfowl populations, their environment, and hunting regulations, with each increment of learning contributing to better management decisions. At the same time, however, much has been changing in the social, institutional, and environmental arenas that provide context for the AHM process. Declines in hunter numbers, competition from more pressing conservation issues, and global-change processes are increasingly challenging waterfowl managers to faithfully reflect the needs and desires of stakeholders, to account for an increasing number of institutional constraints, and to (probabilistically) predict the consequences of regulatory policy in a changing environment. We review the lessons learned from the AHM process so far, and describe emerging challenges and ways in which they may be addressed. We conclude that the practice of AHM has greatly increased an awareness of the roles of social values, trade-offs, and attitudes toward risk in regulatory decision-making. Nevertheless, going forward the waterfowl management community will need to focus not only on the relationships among habitat, harvest, and waterfowl populations, but on the ways in which society values waterfowl and how those values can change over time.&nbsp;</span></p>","language":"English","publisher":"Wiley","doi":"10.1002/wsb.518","usgsCitation":"Johnson, F.A., Boomer, G.S., Williams, B., Nichols, J., and Case, D.J., 2015, Multilevel learning in the adaptive management of waterfowl harvests: 20 years and counting: Wildlife Society Bulletin, v. 39, no. 1, p. 9-19, https://doi.org/10.1002/wsb.518.","productDescription":"11 p.","startPage":"9","endPage":"19","numberOfPages":"11","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-056296","costCenters":[{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true}],"links":[{"id":472343,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1002/wsb.518","text":"Publisher Index Page"},{"id":300245,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"39","issue":"1","publishingServiceCenter":{"id":8,"text":"Raleigh PSC"},"noUsgsAuthors":false,"publicationDate":"2015-01-08","publicationStatus":"PW","scienceBaseUri":"554dde2fe4b082ec54129f2c","contributors":{"authors":[{"text":"Johnson, Fred A. 0000-0002-5854-3695 fjohnson@usgs.gov","orcid":"https://orcid.org/0000-0002-5854-3695","contributorId":2773,"corporation":false,"usgs":true,"family":"Johnson","given":"Fred","email":"fjohnson@usgs.gov","middleInitial":"A.","affiliations":[{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true},{"id":455,"text":"National Wetlands Research Center","active":true,"usgs":true},{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true}],"preferred":true,"id":546478,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Boomer, G.

The flood-inundation maps, accessed through the USGS Flood-Inundation Mapping Science Web site at&nbsp;http://water.usgs.gov/osw/flood_inundation/, depict estimates of the spatial extent and depth of flooding corresponding to selected water levels (stages) at 15 reference streamgages and associated stream reaches in the Blue River Basin. Near-real-time stage data from the streamgages may be obtained from the USGS National Water Information System at&nbsp;http://waterdata.usgs.gov/&nbsp;or the National Weather Service (NWS) Advanced Hydrologic Prediction Service (AHPS) at&nbsp;http://water.weather.gov/ahps/, which also forecasts flood hydrographs at selected sites.</p>\n<p>&nbsp;</p>\n<p>Flood profiles were computed for each of 15 reaches by means of one-dimensional or two-dimensional hydraulic models. The models were calibrated by using the current stage-streamflow relations at 10 USGS streamgages and documented high-water marks from the flood of June 14, 2010. Hydraulic models were then used to compute water-surface profiles for flood stages at 1-foot intervals referenced to the streamgage datum and ranging from the National Weather Service Action stage, or near bankfull streamflow, through the stage corresponding to, or exceeding, the estimated 0.2-percent annual exceedance probability flood (500-year recurrence interval flood).</p>\n<p>&nbsp;</p>\n<p>The simulated water-surface profiles were then combined with a geographic information system (GIS) terrain model derived from light detection and ranging (lidar) data having a vertical accuracy of less than 0.6 foot and maximum nominal horizontal post spacing of 2.46&ndash;3.28 feet to delineate the area flooded at each 1-foot increment of stage. The availability of these flood-inundation maps, along with Internet information regarding current stage from the USGS streamgages and forecasted high-flow stages from the NWS, will provide emergency management personnel and residents with information that is critical for flood response activities such as evacuations and road closures, as well as for postflood recovery efforts.</p>\n<p>&nbsp;</p>\n<p>Additional information in this report includes maps of simulated stream velocity for an 8.2-mile, two-dimensional modeled reach of the Blue River and a Wetland Restoration Suitability Index (WRSI) generated for the study area that was based on hydrologic, topographic, and land-use digital feature layers. The calculated WRSI for the selected flood-plain area ranged from 1 (least suitable for possible wetland mitigation efforts) to 10 (most suitable for possible wetland mitigation efforts). A WRSI of 5 to 10 is most closely associated with existing riparian wetlands in the study area.

St. Laurent and the US icebreaker USCGC Healy. Over 15000 km of bathymetry, sub-bottom profiles, and 16-channel seismic reflection data were acquired over the Canada Basin and Alpha Ridge. Expendable sonobuoys were deployed to collect P-wave refraction and wide angle reflection data to define the regional velocity structure of the sedimentary successions. Although the new seismic profiles tie with existing GSC multichannel seismic lines on the Beaufort Shelf, water-bottom multiples obscure direct correlation of deeper stratigraphic horizons and (at best) basement is poorly imaged.</p><p>We present a 2-D gravity and magnetic model for the southern Canada Basin margin and Beaufort-Mackenzie Basin integrating the new LSSL data with an existing deep crustal seismic reflection profile. The model crosses the slope region, where bathymetry shallows, base-of-sediments is deep, and basement is not imaged because of the water-bottom multiple. The density values used in the model are constrained by empirical relationships between velocity and density rock properties; however, magnetic susceptibility values are based on typical values for the inferred crustal lithologies. Velocity analyses of the new sonobuoy data provide constraints on the composition of the sediments, and enable quantitative mapping of continental, oceanic, and transitional domains within the Canada Basin. The 2-D gravity and magnetic forward model provides estimates for basement and Moho depths, the distribution and depths of magnetic sources, and visualization of the underlying crustal architecture controlling basin formation.</p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"OTC Arctic Technology Conference Proceedings","largerWorkSubtype":{"id":12,"text":"Conference publication"},"conferenceTitle":"OTC Arctic Technology Conference","conferenceDate":"March 23-25, 2015","conferenceLocation":"Copenhagen, Denmark","language":"English","publisher":"One Petro","doi":"10.4043/25470-MS","usgsCitation":"Oakey, G.N., Saltus, R., and Shimeld, J.W., 2015, A crustal structure model of the Beaufort-Mackenzie Margin, southern Canada Basin, <i>in</i> OTC Arctic Technology Conference Proceedings, Copenhagen, Denmark, March 23-25, 2015, https://doi.org/10.4043/25470-MS.","ipdsId":"IP-061942","costCenters":[{"id":211,"text":"Crustal Geophysics and Geochemistry Science Center","active":true,"usgs":true}],"links":[{"id":411426,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Canada, United States","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -148.5313622288357,\n              71.20442863543764\n            ],\n            [\n              -148.5313622288357,\n              62.45942351557227\n            ],\n            [\n              -129.9064593578879,\n              62.45942351557227\n            ],\n            [\n              -129.9064593578879,\n              71.20442863543764\n            ],\n            [\n              -148.5313622288357,\n              71.20442863543764\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationDate":"2015-03-23","publicationStatus":"PW","contributors":{"authors":[{"text":"Oakey, Gordon N.","contributorId":300609,"corporation":false,"usgs":false,"family":"Oakey","given":"Gordon","email":"","middleInitial":"N.","affiliations":[{"id":7219,"text":"Natural Resources Canada","active":true,"usgs":false}],"preferred":false,"id":860941,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Saltus, Richard W. 0000-0001-6920-2936","orcid":"https://orcid.org/0000-0001-6920-2936","contributorId":207255,"corporation":false,"usgs":false,"family":"Saltus","given":"Richard W.","affiliations":[{"id":37502,"text":"NOAA-NCEI, 325 Broadway, NOAA E/GC3, Office 1B507, Boulder, CO","active":true,"usgs":false}],"preferred":false,"id":860942,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Shimeld, John W.","contributorId":300610,"corporation":false,"usgs":false,"family":"Shimeld","given":"John","email":"","middleInitial":"W.","affiliations":[{"id":7219,"text":"Natural Resources Canada","active":true,"usgs":false}],"preferred":false,"id":860943,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Polar bears (</span><i>Ursus maritimus</i><span>) rely on a thick layer of adipose tissue and a dense pelage to ameliorate convective heat loss while moving between sea ice and open water. From 1998 to 2012, we observed an alopecia syndrome in polar bears from the southern Beaufort Sea of Alaska that presented as bilaterally asymmetrical loss of guard hairs and thinning of the undercoat around the head, neck, and shoulders, which, in severe cases, was accompanied by exudation and crusted skin lesions. Alopecia was observed in 49 (3.45%) of the bears sampled during 1,421 captures, and the apparent prevalence varied by years with peaks occurring in 1999 (16%) and 2012 (28%). The probability that a bear had alopecia was greatest for subadults and for bears captured in the Prudhoe Bay region, and alopecic individuals had a lower body condition score than unaffected individuals. The cause of the syndrome remains unknown and future work should focus on identifying the causative agent and potential effects on population vital rates.</span></p>","language":"English","publisher":"Wildlife Disease Association","publisherLocation":"Lawrence, KS","doi":"10.7589/2013-11-301","usgsCitation":"Atwood, T.C., Peacock, E.L., Burek, K., Shearn-Bochsler, V.I., Bodenstein, B.L., Beckmen, K.B., and Durner, G.M., 2015, Prevalence and spatio-temporal variation of an alopecia syndrome in polar bears (Ursus maritimus) of the southern Beaufort Sea: Journal of Wildlife Diseases, v. 51, no. 1, p. 48-59, https://doi.org/10.7589/2013-11-301.","productDescription":"12 p.","startPage":"48","endPage":"59","numberOfPages":"12","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-055759","costCenters":[{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true}],"links":[{"id":298643,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","otherGeospatial":"Beaufort Sea","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -153.193359375,\n              68.87935761076949\n            ],\n            [\n              -125.68359374999999,\n              68.87935761076949\n            ],\n            [\n              -125.68359374999999,\n              73.50346063726599\n            ],\n            [\n              -153.193359375,\n              73.50346063726599\n            ],\n            [\n              -153.193359375,\n              68.87935761076949\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"51","issue":"1","publishingServiceCenter":{"id":12,"text":"Tacoma PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"55095032e4b02e76d757e630","contributors":{"authors":[{"text":"Atwood, Todd C. 0000-0002-1971-3110 tatwood@usgs.gov","orcid":"https://orcid.org/0000-0002-1971-3110","contributorId":4368,"corporation":false,"usgs":true,"family":"Atwood","given":"Todd","email":"tatwood@usgs.gov","middleInitial":"C.","affiliations":[{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":542468,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Peacock, Elizabeth L. 0000-0001-7279-0329 lpeacock@usgs.gov","orcid":"https://orcid.org/0000-0001-7279-0329","contributorId":3361,"corporation":false,"usgs":true,"family":"Peacock","given":"Elizabeth","email":"lpeacock@usgs.gov","middleInitial":"L.","affiliations":[{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true}],"preferred":false,"id":542531,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Burek, K.A.","contributorId":82937,"corporation":false,"usgs":true,"family":"Burek","given":"K.A.","email":"","affiliations":[],"preferred":false,"id":542532,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Shearn-Bochsler, Valerie I. 0000-0002-5590-6518 vbochsler@usgs.gov","orcid":"https://orcid.org/0000-0002-5590-6518","contributorId":3234,"corporation":false,"usgs":true,"family":"Shearn-Bochsler","given":"Valerie","email":"vbochsler@usgs.gov","middleInitial":"I.","affiliations":[{"id":456,"text":"National Wildlife Health Center","active":true,"usgs":true}],"preferred":true,"id":542533,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Bodenstein, Barbara L. 0000-0001-7946-0103 bbodenstein@usgs.gov","orcid":"https://orcid.org/0000-0001-7946-0103","contributorId":4389,"corporation":false,"usgs":true,"family":"Bodenstein","given":"Barbara","email":"bbodenstein@usgs.gov","middleInitial":"L.","affiliations":[{"id":456,"text":"National Wildlife Health Center","active":true,"usgs":true}],"preferred":true,"id":542534,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Beckmen, Kimberlee B.","contributorId":12770,"corporation":false,"usgs":true,"family":"Beckmen","given":"Kimberlee","email":"","middleInitial":"B.","affiliations":[],"preferred":false,"id":542535,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Durner, George M. 0000-0002-3370-1191 gdurner@usgs.gov","orcid":"https://orcid.org/0000-0002-3370-1191","contributorId":3576,"corporation":false,"usgs":true,"family":"Durner","given":"George","email":"gdurner@usgs.gov","middleInitial":"M.","affiliations":[{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":542536,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

In contrast, pore-pressure models demonstrate that a combination of brine production and wastewater injection near the fault generated subsurface pressures sufficient to induce earthquakes on near-critically stressed faults.

Aspen forests and woodlands provide numerous ecosystem services, such as high primary productivity and biodiversity, retention and storage of environmental variables (precipitation, temperature, snow&ndash;water equivalent) that affect the spring and fall phenology of the aspen woodland communities of southwestern Colorado. We assessed the land surface phenology of aspen woodlands using two phenology indices, start of season time (SOST) and end of season time (EOST), from the U.S. Geological Survey (USGS) database of conterminous U.S. phenological indicators over an 11-year time period (2001&ndash;2011). These indicators were developed with 250 m resolution remotely sensed data from the Moderate Resolution Imaging Spectroradiometer processed to highlight vegetation response. We compiled data on SOST, EOST, elevation, precipitation, air temperature, and snow water equivalent (SWE) for selected sites having more than 80% cover by aspen woodland communities. In the 11-year time frame of our study, EOST had significant positive correlation with minimum fall temperature and significant negative correlation with fall precipitation. SOST had a significant positive correlation with spring SWE and spring maximum temperature.</p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.ecolind.2014.05.033","usgsCitation":"Meier, G.A., Brown, J., Evelsizer, R.J., and Vogelmann, J., 2015, Phenology and climate relationships in aspen (Populus tremuloides Michx.) forest and woodland communities of southwestern Colorado: Ecological Indicators, v. 48, p. 189-197, https://doi.org/10.1016/j.ecolind.2014.05.033.","productDescription":"9 p.","startPage":"189","endPage":"197","numberOfPages":"9","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-045382","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":294919,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Colorado","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -109.07739323500078,\n              38.82479148331984\n            ],\n            [\n              -109.07739323500078,\n              37.04810861806919\n            ],\n            [\n              -105.56044097270126,\n              37.04810861806919\n            ],\n            [\n              -105.56044097270126,\n              38.82479148331984\n            ],\n            [\n              -109.07739323500078,\n              38.82479148331984\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"48","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"542fbaa6e4b092f17df61d6e","contributors":{"authors":[{"text":"Meier, Gretchen A.","contributorId":96615,"corporation":false,"usgs":true,"family":"Meier","given":"Gretchen","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":489306,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Brown, Jesslyn F. 0000-0002-9976-1998","orcid":"https://orcid.org/0000-0002-9976-1998","contributorId":26243,"corporation":false,"usgs":true,"family":"Brown","given":"Jesslyn F.","affiliations":[{"id":223,"text":"Earth Resources Observation and Science (EROS) Center (Geography)","active":false,"usgs":true}],"preferred":false,"id":489304,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Evelsizer, Ross J.","contributorId":80211,"corporation":false,"usgs":true,"family":"Evelsizer","given":"Ross","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":489305,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Vogelmann, James E. 0000-0002-0804-5823 vogel@usgs.gov","orcid":"https://orcid.org/0000-0002-0804-5823","contributorId":649,"corporation":false,"usgs":true,"family":"Vogelmann","given":"James E.","email":"vogel@usgs.gov","affiliations":[{"id":223,"text":"Earth Resources Observation and Science (EROS) Center (Geography)","active":false,"usgs":true}],"preferred":false,"id":489303,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

The Qinghai-Tibetan Plateau is regarded as an ideal area due to its undisturbed features with low population and relatively high snow cover. We used 500 m Moderate Resolution Imaging Spectroradiometer (MODIS) datasets during 2001&ndash;2010 to examine the snow&ndash;vegetation relationships, specifically, (1) the influence of snow melting date on vegetation green-up date and (2) the effects of snow cover duration on vegetation greenness. The results showed that the alpine vegetation responded strongly to snow phenology (i.e., snow melting date and snow cover duration) over large areas of the Qinghai-Tibetan Plateau. Snow melting date and vegetation green-up date were significantly correlated (p &lt; 0.1) in 39.9% of meadow areas (accounting for 26.2% of vegetated areas) and 36.7% of steppe areas (28.1% of vegetated areas). Vegetation growth was influenced by different seasonal snow cover durations (SCDs) in different regions. Generally, the December&ndash;February and March&ndash;May SCDs played a significantly role in vegetation growth, both positively and negatively, depending on different water source regions.

Because of their relatively flat topography and riverine origin, floodplains in the upper reaches of reservoirs provide broad expanses of vegetation within a narrow range of reservoir water levels. Elsewhere in the reservoir, topography creates a band of shallow water along the contour of the reservoir where vegetation often does not grow. Thus, as water levels rise, floodplains may be the first vegetated habitats inundated within the reservoir. We hypothesized that shallow water in reservoir floodplains would attract spawning white crappies <i>Pomoxis annularis</i> earlier than reservoir embayments. Crappie relative abundance over five years in floodplains and embayments of four reservoirs increased as spawning season approached, peaked, and decreased as fish exited shallow water. Relative abundance peaked earlier in floodplains than embayments, and the difference was magnified with higher water levels. Early access to suitable spawning habitat promotes earlier spawning and may increase population fitness. Recognition of the importance of reservoir floodplains, an understanding of how reservoir water levels can be managed to provide timely connectivity to floodplains, and conservation of reservoir floodplains may be focal points of environmental management in reservoirs.</p>","language":"English","publisher":"Kluwer Academic Publishers","publisherLocation":"Dordrecht","doi":"10.1007/s10641-014-0276-1","usgsCitation":"Miranda, L.E., Dagel, J.D., Kaczka, L.J., Mower, E., and Wigen, S.L., 2015, Floodplains within reservoirs promote earlier spawning of white crappies <i>Pomoxis annularis</i>: Environmental Biology of Fishes, v. 98, no. 1, p. 469-476, https://doi.org/10.1007/s10641-014-0276-1.","productDescription":"8 p.","startPage":"469","endPage":"476","numberOfPages":"8","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-052168","costCenters":[{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true}],"links":[{"id":302459,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"98","issue":"1","publishingServiceCenter":{"id":8,"text":"Raleigh PSC"},"noUsgsAuthors":false,"publicationDate":"2014-05-11","publicationStatus":"PW","scienceBaseUri":"558e77b7e4b0b6d21dd65956","contributors":{"authors":[{"text":"Miranda, Leandro E. 0000-0002-2138-7924 smiranda@usgs.gov","orcid":"https://orcid.org/0000-0002-2138-7924","contributorId":531,"corporation":false,"usgs":true,"family":"Miranda","given":"Leandro","email":"smiranda@usgs.gov","middleInitial":"E.","affiliations":[{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true}],"preferred":true,"id":556872,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Dagel, Jonah D.","contributorId":143699,"corporation":false,"usgs":false,"family":"Dagel","given":"Jonah","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":557143,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kaczka, Levi J.","contributorId":143806,"corporation":false,"usgs":false,"family":"Kaczka","given":"Levi","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":557144,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Mower, Ethan","contributorId":143702,"corporation":false,"usgs":false,"family":"Mower","given":"Ethan","email":"","affiliations":[],"preferred":false,"id":557145,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Wigen, S.

The southern Appalachian Mountains are the southern extent of the geographic range of native <i>Salvelinus fontinalis</i> and naturalized <i>Oncorhynchus mykiss</i> and <i>Salmo trutta</i> in eastern North America. We predicted distributions of these peripheral, headwater wild trout populations at a fine scale to serve as a planning and management tool for resource managers to maximize resistance and resilience of these populations in the face of anthropogenic stressors. We developed correlative logistic regression models to predict occurrence of brook trout, rainbow trout, and brown trout for every interconfluence stream reach in the study area. A stream network was generated to capture a more consistent representation of headwater streams. Each of the final models had four significant metrics in common: stream order, fragmentation, precipitation, and land cover. Strahler stream order was found to be the most influential variable in two of the three final models and the second most influential variable in the other model. Greater than 70% presence accuracy was achieved for all three models. The underrepresentation of headwater streams in commonly used hydrography datasets is an important consideration that warrants close examination when forecasting headwater species distributions and range estimates. Additionally, it appears that a relative watershed position metric (e.g., stream order) is an important surrogate variable (even when elevation is included) for biotic interactions across the landscape in areas where headwater species distributions are influenced by topographical gradients.</p>","language":"English","publisher":"Blackwell Pub.
