In this report, the potential for chronic PAH exposure in fish is reported, by measurement of recalcitrant, higher molecular weight PAHs in tissues of fish previously investigated for PAH metabolites in bile. A total of 34 PAHs (20 PAHs, 11 alkylated PAHs, and 3 polycyclic aromatic thiophenes) were targeted. In addition, legacy contaminants—polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs),—and current contaminants, polybrominated diphenylethers (PBDEs) linked to endocrine disruption, were measured by gas chromatography with electron-capture or mass spectrometric detection, to form a more complete picture of the contaminant-related status of fishes at oil production platforms in the Southern California Bight. No hydrocarbon profiles or unresolved complex hydrocarbon background were found in fish from platforms and from natural areas, and concentrations of aliphatics were low less than 100 nanograms per gram (ng/g) per component]. Total-PAH concentrations in fish ranged from 15 to 37 ng/g at natural areas and from 8.7 to 22 ng/g at platforms. Profiles of PAHs were similar at all natural and platform sites, consisting mainly of naphthalene and methylnaphthalenes, phenanthrene, fluoranthene, and pyrene. Total-PCB concentrations (excluding non-ortho-chloro-substituted congeners) in fish were low, ranging from 7 to 22 ng/g at natural areas and from 10 to 35 ng/g at platforms. About 50 percent of the total-PCBs at all sites consisted of 11 congeners: 153 > 138/163/164 > 110 > 118 > 15 > 99 > 187 > 149 > 180. Most OCPs, except dichlorodiphenyltrichloroethane (DDT)-related compounds, were not detectable or were at concentrations of less than 1 ng/g in fish. <i>p,p′</i>-dichlorodiphenyltrichloroethane (<i>p,p′</i>-DDE) ranged from 5.6 to 33 ng/g at natural areas and from 17 to 76 ng/g at platforms, and comprised greater than 90 percent of the total-DDT concentrations at all sites. The only detectable PBDE congeners were PBDE-47 and PBDE-100, the total concentrations of which ranged from 0.4 to 1.8 ng/g at natural areas and from 0.5 to 3.0 ng/g at platforms. Total-PAH, -PCB, and -DDT concentrations were compared with other Southern California Bight studies involving shoreline mussel, (<i>Mytilus</i> Species, Kimbrough and others, 2008) and near shore sampling (Pacific sanddab, Schiff and Allen, 2000). At corresponding sites, only total-PCB concentrations agreed well with results from this study; total-DDT concentrations were generally much lower than concentrations documented in previous studies for samples collected nearer to shore by sewage treatment outfalls or 14 years earlier or closer in time to when DDT production was halted (1970). Natural areas and platforms in the Bight do not appear to be affected by harbor or urban pollution. Platforms were no more polluted than the nearby natural areas, with these locations exhibiting only low concentrations of PAHs, PCBs, DDTs, and other contaminants.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr20131046","collaboration":"Prepared in cooperation with the Bureau of Ocean Energy Management","usgsCitation":"Gale, R.W., Tanner, M.J., Love, M., Nishimoto, M.M., and Schroeder, D.M., 2013, Comparison of aliphatic hydrocarbons, polycyclic aromatic hydrocarbons, polychlorinated biphenyls, polybrominated diphenylethers, and organochlorine pesticides in Pacific sanddab (Citharichthys sordidus) from offshore oil platforms and natural reefs along the California coast: U.S. Geological Survey Open-File Report 2013-1046, Report: vi, 34 p.; Supplemental tables, https://doi.org/10.3133/ofr20131046.","productDescription":"Report: vi, 34 p.; Supplemental tables","numberOfPages":"42","onlineOnly":"Y","additionalOnlineFiles":"Y","costCenters":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"links":[{"id":270454,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr20131046.gif"},{"id":270452,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2013/1046/ofr2013-1046.pdf"},{"id":270453,"type":{"id":22,"text":"Related Work"},"url":"https://pubs.usgs.gov/of/2013/1046/downloads/supplemental_tables.xlsx"},{"id":270451,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2013/1046/"}],"country":"United States","state":"California","otherGeospatial":"Southern California Bight","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -120.28,33.09 ], [ -120.28,34.46 ], [ -118.12,34.46 ], [ -118.12,33.09 ], [ -120.28,33.09 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"515befdce4b075500ee5c9fe","contributors":{"authors":[{"text":"Gale, Robert W. 0000-0002-8533-141X rgale@usgs.gov","orcid":"https://orcid.org/0000-0002-8533-141X","contributorId":2808,"corporation":false,"usgs":true,"family":"Gale","given":"Robert","email":"rgale@usgs.gov","middleInitial":"W.","affiliations":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"preferred":true,"id":477012,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Tanner, Michael J.","contributorId":55115,"corporation":false,"usgs":true,"family":"Tanner","given":"Michael","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":477014,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Love, Milton S.","contributorId":74652,"corporation":false,"usgs":true,"family":"Love","given":"Milton S.","affiliations":[],"preferred":false,"id":477016,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Nishimoto, Mary M.","contributorId":54083,"corporation":false,"usgs":true,"family":"Nishimoto","given":"Mary","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":477013,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Schroeder, Donna M.","contributorId":67604,"corporation":false,"usgs":true,"family":"Schroeder","given":"Donna","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":477015,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

The large runoff event in 2011 provided an opportunity to examine characteristics of sediment transport in the Missouri River at high-magnitude streamflow and for a long duration. The purpose of this report is to describe sediment characteristics during the 2011 high-flow conditions at six selected sites on the Missouri River, two in the middle region of the basin between Lake Sakakawea and Lake Oahe in North Dakota, and four downstream from Gavins Point Dam along the Nebraska-South Dakota and Nebraska-Iowa borders.\n\nA wider range in suspended-sediment concentration was observed in the middle segment of the Missouri River compared to sites in the lower segment. In the middle segment of the Missouri River, suspended-sediment concentrations increased and peaked as flows increased and started to plateau; however, while flows were still high and steady, suspended-sediment concentrations decreased and suspended-sediment grain sizes coarsened, indicating the decrease possibly was related to fine-sediment supply limitations.\n\nMeasured bedload transport rates in the lower segment of the Missouri River (sites 3 to 6) were consistently higher than those in the middle segment (sites 1 and 2) during the high-flow conditions in 2011. The median bedload transport rate measured at site 1 was 517 tons per day and at site 2 was 1,500 tons per day. Measured bedload transport rates were highest at site 3 then decreased downstream to site 5, then increased at site 6. The median bedload transport rates were 22,100 tons per day at site 3; 5,640 tons per day at site 4; 3,930 tons per day at site 5; and 8,450 tons per day at site 6. At the two sites in the middle segment of the Missouri River, the greatest bedload was measured during the recession of the streamflow hydrograph. A similar pattern was observed at sites 3–5 in the lower segment of the Missouri River, where the greatest bedload was measured later in the event on the recession of the streamflow hydrograph, although the change in bedload was not as dramatic as observed at the sites in the middle segment of the Missouri River.\n\nWith the exception of site 3, the total-sediment load on the Missouri River was highest at the beginning of the high-flow event and decreased as streamflow decreased. In the middle segment of the Missouri River, measured total-sediment load ranged from 2,320 to 182,000 tons per day at site 1 and from 3,190 to 279,000 tons per day at site 2. In the lower segment of the Missouri River, measured total-sediment load ranged from 50,600 to 223,000 tons per day at site 4; from 23,500 to 403,000 tons per day at site 5; and from 52,700 to 273,000 tons per day at site 6.\n\nThe total-sediment load was dominated by suspended sediment at all of the sites measured on the Missouri River in 2011. In general, the percentage of total-sediment load that was bedload increased as the streamflow decreased, although this pattern was more prevalent at sites in the middle segment than those in the lower segment. The suspended-sediment load comprised an average of 93 percent of the total load, with the exception of site 3, where the suspended-sediment load comprised only 72 percent of the total-sediment load.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/sir20135006","collaboration":"Prepared in cooperation with the U.S. Army Corps of Engineers, Omaha District","usgsCitation":"Galloway, J.M., Rus, D.L., and Alexander, J.S., 2013, Characteristics of sediment transport at selected sites along the Missouri River during the high-flow conditions of 2011: U.S. Geological Survey Scientific Investigations Report 2013-5006, iv, 31 p., https://doi.org/10.3133/sir20135006.","productDescription":"iv, 31 p.","numberOfPages":"40","onlineOnly":"Y","additionalOnlineFiles":"N","temporalStart":"2011-01-01","temporalEnd":"2011-12-31","costCenters":[{"id":478,"text":"North Dakota Water Science Center","active":true,"usgs":true},{"id":34685,"text":"Dakota Water Science Center","active":true,"usgs":true}],"links":[{"id":270473,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/sir20135006.gif"},{"id":270471,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/sir/2013/5006/"},{"id":270472,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/sir/2013/5006/sir13-5006.pdf"}],"country":"United States","otherGeospatial":"Missouri River","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -116.0,38.4 ], [ -116.0,49.0 ], [ -90.1,49.0 ], [ -90.1,38.4 ], [ -116.0,38.4 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"515befcfe4b075500ee5c9f6","contributors":{"authors":[{"text":"Galloway, Joel M. 0000-0002-9836-9724 jgallowa@usgs.gov","orcid":"https://orcid.org/0000-0002-9836-9724","contributorId":1562,"corporation":false,"usgs":true,"family":"Galloway","given":"Joel","email":"jgallowa@usgs.gov","middleInitial":"M.","affiliations":[{"id":478,"text":"North Dakota Water Science Center","active":true,"usgs":true},{"id":34685,"text":"Dakota Water Science Center","active":true,"usgs":true}],"preferred":true,"id":477017,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Rus, Dave L.","contributorId":78623,"corporation":false,"usgs":true,"family":"Rus","given":"Dave","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":477019,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Alexander, Jason S. 0000-0002-1602-482X jalexand@usgs.gov","orcid":"https://orcid.org/0000-0002-1602-482X","contributorId":2802,"corporation":false,"usgs":true,"family":"Alexander","given":"Jason","email":"jalexand@usgs.gov","middleInitial":"S.","affiliations":[{"id":464,"text":"Nebraska Water Science Center","active":true,"usgs":true}],"preferred":false,"id":477018,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Interactions among physiography, ecology, geology, and current and past climate have largely determined the location and properties of aquifers as well as the timing and magnitude of fluxes to, from, and within the groundwater system. The climate ranges from maritime in the southern portion of the state to continental in the Interior, and arctic on the North Slope. During the Quaternary period, topography and rock type have combined with glacial and periglacial processes to develop the unconsolidated alluvial aquifers of Alaska and have resulted in highly heterogeneous hydrofacies. In addition, the long persistence of frozen ground, whether seasonal or permanent, greatly affects the distribution of aquifer recharge and discharge. Because of high runoff, a high proportion of groundwater use, and highly variable permeability controlled in part by permafrost and seasonally frozen ground, understanding groundwater/surface-water interactions and the effects of climate change is critical for understanding groundwater availability and the movement of natural and anthropogenic contaminants.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Hydrogeology Journal","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer","publisherLocation":"Amsterdam, Netherlands","doi":"10.1007/s10040-012-0940-5","usgsCitation":"Callegary, J., Kikuchi, C., Koch, J.C., Lilly, M.R., and Leake, S.A., 2013, Review: groundwater in Alaska (USA): Hydrogeology Journal, v. 21, no. 1, p. 25-39, https://doi.org/10.1007/s10040-012-0940-5.","productDescription":"15 p.","startPage":"25","endPage":"39","ipdsId":"IP-037267","costCenters":[{"id":128,"text":"Arizona Water Science Center","active":true,"usgs":true}],"links":[{"id":270492,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":270490,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10040-012-0940-5"}],"country":"United States","state":"Alaska","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 172.5,51.2 ], [ 172.5,71.4 ], [ -130.0,71.4 ], [ -130.0,51.2 ], [ 172.5,51.2 ] ] ] } } ] }","volume":"21","issue":"1","noUsgsAuthors":false,"publicationDate":"2013-01-10","publicationStatus":"PW","scienceBaseUri":"515befdee4b075500ee5ca0a","contributors":{"authors":[{"text":"Callegary, J.B.","contributorId":71769,"corporation":false,"usgs":true,"family":"Callegary","given":"J.B.","affiliations":[],"preferred":false,"id":477045,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kikuchi, C.P.","contributorId":85479,"corporation":false,"usgs":true,"family":"Kikuchi","given":"C.P.","email":"","affiliations":[],"preferred":false,"id":477046,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Koch, Joshua C. 0000-0001-7180-6982 jkoch@usgs.gov","orcid":"https://orcid.org/0000-0001-7180-6982","contributorId":202532,"corporation":false,"usgs":true,"family":"Koch","given":"Joshua","email":"jkoch@usgs.gov","middleInitial":"C.","affiliations":[{"id":120,"text":"Alaska Science Center Water","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true}],"preferred":true,"id":477047,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Lilly, M.

Because of ongoing development in the drinking-water source area, the Cambridge water supply has the potential to be affected by a wide variety of contaminants. The U.S. Geological Survey (USGS) has monitored surface-water quality in the Hobbs Brook and Stony Brook Basins, which compose the drinking-water source area, since 1997 (water year 1997) through continuous monitoring and discrete sample collection and, since 2004, through systematic collection of streamwater samples during base-flow and stormflow conditions at five primary sampling stations in the drinking-water source area. Four primary sampling stations are on small tributaries in the Hobbs Brook and Stony Brook Basins; the fifth primary sampling station is on the main stem of Stony Brook and drains about 93 percent of the Cambridge drinking-water source area. Water samples also were collected at six secondary sampling stations, including Fresh Pond Reservoir, the final storage reservoir for the raw water supply. Storm runoff and base-flow concentrations of calcium (Ca), chloride (Cl), sodium (Na), and sulfate (SO<sub>4</sub>) were estimated from continuous records of streamflow and specific conductance for six monitoring stations, which include the five primary sampling stations. These data were used to characterize current water-quality conditions, estimate loads and yields, and describe trends in Cl and Na in the tributaries and main-stem streams in the Hobbs Brook and Stony Brook Basins. These data also were used to describe how streamwater quality is affected by various watershed characteristics and provide information to guide future watershed management. Water samples were analyzed for physical properties and concentrations of Ca, Cl, Na, and SO<sub>4</sub>, total nitrogen (TN), total phosphorus (TP), caffeine, and a suite of 59 polar pesticides. Values of physical properties and constituent concentrations varied widely, particularly in samples from tributaries. Median concentrations of Ca, Cl, Na, and SO4 in samples collected in the Hobbs Brook Basin (39.8, 392, 207, and 21.7 milligrams per liter (mg/L), respectively) were higher than those for the Stony Brook Basin (17.8, 87.7, 49.7, and 14.7 mg/L, respectively). These differences in major ion concentrations are likely related to the low percentages of developed land and impervious area in the Stony Brook Basin. Concentrations of dissolved Cl and Na in samples, and those estimated from continuous records of specific conductance (particularly during base flow), often were greater than the U.S. Environmental Protection Agency (USEPA) secondary drinking-water guideline for Cl (250 mg/L), the chronic aquatic-life guideline for Cl (230 mg/L), and the Commonwealth of Massachusetts, Executive Office of Energy and Environmental Affairs drinking-water guideline for Na (20 mg/L). Mean annual flow-weighted concentrations of Ca, Cl, and Na were generally positively correlated with the area of roadway land use in the subbasins. Correlations between mean annual concentrations of Ca and SO<sub>4</sub> in base flow and total roadway, total impervious, and commercial-industrial land uses were statistically significant. Concentrations of TN (range of 0.42 to 5.13 mg/L in all subbasins) and TP (range of 0.006 to 0.80 mg/L in all subbasins) in tributary samples did not differ substantially between the Hobbs Brook and Stony Brook Basins. Concentrations of TN and TP in samples collected during water years 2004–07 exceeded proposed reference concentrations of 0.57 and 0.024 mg/L, in 94 and 56 percent of the samples, respectively. Correlations between annual flow-weighted concentrations of TN and percentages of recreational land use and water-body area were statistically significant; however, no significant relation was found between TP and available land-use information. The volume of streamflow affected water-quality conditions at the primary sampling stations. Turbidity and concentrations of TP were positively correlated with streamflow. In contrast, concentrations of major ions were negatively correlated with streamflow, indicating that these constituents were diluted during stormflows. Concentrations of TN were not correlated with streamflow. Twenty-five pesticides and caffeine were detected in water samples collected in the drinking-water source area and in raw water collected from the Cambridge water-treatment facility intake at the Fresh Pond Reservoir. Imidacloprid, norflurazon, and siduron were the most frequently detected pesticides with the frequency of detections ranging from about 24 to 41 percent. Caffeine was detected in about 37 percent of water samples at concentrations ranging from 0.003 to 1.82 micrograms per liter (μg/L). Although some of the detected pesticides degrade rapidly, norflurazon and siduron are relatively stable and are able to immigrate though the serial reservoir system. Concentrations of 2,4-D, carbaryl, imazaquin, MCPA (2-methyl-4-chlorophenoxyacetic acid), metsulfuron-methyl, norflurazon, siduron, and caffeine were detected more frequently in stormflow samples than in base-flow samples. Concentrations of pesticides did not exceed USEPA drinking-water guidelines or other health standards and were several orders of magnitude less than the lethal exposure level established for several fish species common to the drinking-water source area. Imidacloprid, an insecticide, was the only pesticide with a concentration exceeding available long-term aquatic-life guidelines. Several pesticides correlated significantly with the amount of recreational, residential, and commercial area in the tributary subbasins. Mean annual base-flow concentrations of caffeine correlated significantly with parking-lot land use. For most tributaries, about 70 percent of the annual loads of Ca, Cl, Na, and SO<sub>4</sub> were associated with base flow. Upward temporal trends in annual loads of Cl and Na were identified on the basis of data for water years 1998 to 2008 for the outlet of the Cambridge Reservoir in the Hobbs Brook Basin; however, similar trends were not identified for the main stem of Stony Brook downstream from the reservoir. The proportions of the TN load attributed to base flow and stormflow were similar in each tributary. In contrast, more than 83 percent of the TP loads in the tributaries and about 73 percent of the TP load in main stem of Stony Brook were associated with stormflow. Mean annual yields of Ca, Cl, Na, and SO<sub>4</sub> in the Stony Brook Reservoir watershed, which represents most of the drinking-water source area, were 14, 85, 46, and 9 metric tons per square kilometer, respectively. Mean annual yields among the individual tributary subbasins varied extensively. Mean annual yields for the respective constituents increased with an increase in roadway and parking-lot area in the tributary subbasins. Mean annual yields of TN in the tributary subbasins ranged from about 740 to more than 1,200 kilograms per square kilometer and exceeded the yield for the main stem of Stony Brook at USGS station 01104460 upstream from the Stony Brook Reservoir. Mean annual yields estimated for the herbicides 2,4-D and imidacloprid ranged from 34 to 310 grams per square kilometer (g/km<sup>2</sup>) and 3 to 170 g/km<sup>2</sup>, respectively. Annual loads for 2,4-D were entirely associated with stormflow. The largest annual load for imidacloprid was estimated for the main stem of Stony Brook; however, the highest annual yield for this pesticide, as well as for benomyl, carbaryl, metalaxyl, and propiconazole, was estimated for a tributary to the Stony Brook Reservoir that drains largely residential and recreational areas. Mean annual yields for the herbicide siduron ranged from 6.9 to 35 g/km<sup>2</sup> with most of the loads associated with stormflow. Mean annual yields for the insecticide diuron ranged from 2.1 to 4.4 g/km<sup>2</sup>. Annual yields of caffeine ranged from 11 to 410 g/km<sup>2</sup>.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/sir20135039","collaboration":"Prepared in cooperation with the City of Cambridge, Massachusetts, Water Department","usgsCitation":"Smith, K.P., 2013, Water-quality conditions, and constituent loads and yields in the Cambridge drinking-water source area, Massachusetts, water years 2005–07: U.S. Geological Survey Scientific Investigations Report 2013-5039, xii, 76 p., https://doi.org/10.3133/sir20135039.","productDescription":"xii, 76 p.","numberOfPages":"76","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":466,"text":"New England Water Science Center","active":true,"usgs":true}],"links":[{"id":270487,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/sir20135039.gif"},{"id":270485,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/sir/2013/5039/"},{"id":270486,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/sir/2013/5039/pdf/sir2013-5039_report_508.pdf"}],"country":"United States","state":"Massachusetts","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -71.20,42.21 ], [ -71.20,42.27 ], [ -71.11,42.27 ], [ -71.11,42.21 ], [ -71.20,42.21 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"515befe0e4b075500ee5ca16","contributors":{"authors":[{"text":"Smith, Kirk P. 0000-0003-0269-474X kpsmith@usgs.gov","orcid":"https://orcid.org/0000-0003-0269-474X","contributorId":1516,"corporation":false,"usgs":true,"family":"Smith","given":"Kirk","email":"kpsmith@usgs.gov","middleInitial":"P.","affiliations":[{"id":466,"text":"New England Water Science Center","active":true,"usgs":true},{"id":376,"text":"Massachusetts Water Science Center","active":true,"usgs":true}],"preferred":true,"id":477052,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Lidar imagery of the Wenas Valley illuminated the west-northwest-trending, 2- to 8-meter-high scarp as it bisected alluvial fans developed at the mouths of canyons along the south side of Umtanum Ridge. The alignment of the scarp and aeromagnetic lineaments suggested that the scarp may be a product of and controlled by the same tectonic structure that produced the magnetic lineaments. Several large landslides mapped in the area demonstrated the potential for large mass-wasting events in the area. In order to test whether the scarp was the result of an earthquake-generated surface rupture or a landslide, trenches were excavated at Hessler Flats and McCabe Place. The profiles of bedrock and soil stratigraphy that underlie the scarp in each trench were photographed, mapped, and described, and a sequence of depositional and deformational events established for each trench. The McCabe Place trench exposed a sequence of volcaniclastic deposits overlain by soils and alluvial deposits separated by three unconformities. Six normal faults and two possible reverse faults deformed the exposed strata. Crosscutting relations indicated that up to five earthquakes occurred on a blind reverse fault, and a microprobe analysis of lapilli suggested that the earliest faulting occurred after 47,000 years before present. The Hessler Flat trench exposure revealed weathered bedrock that abuts loess and colluvium deposits and is overlain by soil, an upper sequence of loess, and colluvium. The latter two units bury a distinctive paloesol.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/sim3239","usgsCitation":"Sherrod, B.L., Barnett, E., Knepprath, N., and Foit, F.F., 2013, Paleoseismology of a possible fault scarp in Wenas Valley, central Washington: U.S. Geological Survey Scientific Investigations Map 3239, Sheet: 46\" x 36\" PDF, https://doi.org/10.3133/sim3239.","productDescription":"Sheet: 46\" x 36\" PDF","onlineOnly":"Y","additionalOnlineFiles":"N","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":270484,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/sim3239.gif"},{"id":270482,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/sim/3239/"},{"id":270483,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/sim/3239/sim3239_sheet.pdf"}],"country":"United States","state":"Washington","otherGeospatial":"Wenas Valley","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -120.739875,46.809988 ], [ -120.739875,46.858078 ], [ -120.646877,46.858078 ], [ -120.646877,46.809988 ], [ -120.739875,46.809988 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"515befdde4b075500ee5ca06","contributors":{"authors":[{"text":"Sherrod, Brian L.","contributorId":16874,"corporation":false,"usgs":true,"family":"Sherrod","given":"Brian","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":477048,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Barnett, Elizabeth A.","contributorId":41550,"corporation":false,"usgs":true,"family":"Barnett","given":"Elizabeth A.","affiliations":[],"preferred":false,"id":477050,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Knepprath, Nichole","contributorId":18233,"corporation":false,"usgs":true,"family":"Knepprath","given":"Nichole","affiliations":[],"preferred":false,"id":477049,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Foit, Franklin F.

More than two thousand high-resolution hydrofacies models representing seven groups of alluvial settings are built to test the effects of varying facies proportions, mean length and its anisotropy ratio, juxtapositional tendencies, and sub-facies heterogeneity. Results show that the volumetric fraction (P(Z)) of floodplain layers classified by their thicknesses Z controls the non-Fickian tailing of tracer transport at late times. A simple quantitative relationship S<sub>BTC</sub>≈S<sub>P(Z)</sub>/2-1 is built based on a multi-rate mass transfer analysis, where S<sub>BTC</sub> is the slope of the power-law portion of tracer breakthrough curve, and S<sub>P(Z)</sub> denotes the slope of the power-law portion of the distribution of P(Z) which can be measured, e.g., in core logs. At early times, the mean length of hydrofacies affects the non-Fickian tailing by controlling the channeling of flow in high-permeability non-floodplain materials and the sequestration in surrounding low-permeability floodplain layers. The competition between channeling and sequestration generates complex pre-asymptotic features, including sublinear growth of plume mean displacement, superlinear growth of plume variance, and skewed mass distribution. Those observations of the influence of medium heterogeneity on tracer transport at early and late times may lead to development of nonlocal transport models that can be parameterized using measurable aquifer characteristics.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Advances in Water Resources","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.advwatres.2013.01.004","usgsCitation":"Zhang, Y., Green, C.T., and Fogg, G., 2013, The impact of medium architecture of alluvial settings on non-Fickian transport: Advances in Water Resources, v. 54, p. 78-99, https://doi.org/10.1016/j.advwatres.2013.01.004.","productDescription":"22 p.","startPage":"78","endPage":"99","numberOfPages":"22","ipdsId":"IP-042821","costCenters":[{"id":148,"text":"Branch of Regional Research-Western Region","active":false,"usgs":true}],"links":[{"id":278945,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":278944,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.advwatres.2013.01.004"}],"volume":"54","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"527cc495e4b0850ea050cec0","contributors":{"authors":[{"text":"Zhang, Yong","contributorId":19029,"corporation":false,"usgs":true,"family":"Zhang","given":"Yong","affiliations":[],"preferred":false,"id":470661,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Green, Christopher T. 0000-0002-6480-8194 ctgreen@usgs.gov","orcid":"https://orcid.org/0000-0002-6480-8194","contributorId":1343,"corporation":false,"usgs":true,"family":"Green","given":"Christopher","email":"ctgreen@usgs.gov","middleInitial":"T.","affiliations":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"preferred":true,"id":470660,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Fogg, Graham E.","contributorId":68779,"corporation":false,"usgs":true,"family":"Fogg","given":"Graham E.","affiliations":[],"preferred":false,"id":470662,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Continuation of these trends could negatively impact pond-breeding amphibians, especially those that rely on winter and spring rains to fill seasonal wetlands, trigger breeding, and ensure reproductive success. From 2009 to 2012, we monitored Spring and Fall presence of aquatic stages (larval and paedomorphic, gilled adult) of a winter-breeding amphibian (the mole salamander, Ambystoma talpoideum) and used multi-season models to estimate occupancy, local colonization and extinction. Seasonal estimates of occupancy, corrected for imperfect detection, declined from 22.3 % of ponds in Spring 2009 to 9.9 % in Fall 2012. Our best supported model suggested that changes in occupancy were driven by increased rates of extinction that corresponded with drought-related drying of ponds. Based on uncertainty in climate change projections for the Southeast, we present a conceptual model of predicted changes in wetland hydroperiods across a landscape with projected decreases and increases in future precipitation. Such precipitation changes could alter wetland hydroperiods, facilitate extinctions of species adapted to short, intermediate or long hydroperiod environments and, ultimately, modify the composition of amphibian communities within freshwater wetland ecosystems.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Wetlands","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer","doi":"10.1007/s13157-013-0391-3","usgsCitation":"Walls, S., Barichivich, W.J., Brown, M.E., Scott, D., and Hossack, B.R., 2013, Influence of drought on salamander occupancy of isolated wetlands on the southeastern Coastal Plain of the United States: Wetlands, v. 33, no. 2, p. 345-354, https://doi.org/10.1007/s13157-013-0391-3.","productDescription":"10 p.","startPage":"345","endPage":"354","numberOfPages":"10","temporalStart":"2009-01-01","temporalEnd":"2012-12-31","ipdsId":"IP-039225","costCenters":[{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true}],"links":[{"id":278048,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":278047,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s13157-013-0391-3"}],"country":"United States","state":"Florida","otherGeospatial":"St. Marks National Wildlife Refuge","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -84.50407,29.968825 ], [ -84.50407,30.175794 ], [ -84.005432,30.175794 ], [ -84.005432,29.968825 ], [ -84.50407,29.968825 ] ] ] } } ] }","volume":"33","issue":"2","noUsgsAuthors":false,"publicationDate":"2013-03-08","publicationStatus":"PW","scienceBaseUri":"5242b465e4b096ee624641f8","contributors":{"authors":[{"text":"Walls, Susan C. 0000-0001-7391-9155","orcid":"https://orcid.org/0000-0001-7391-9155","contributorId":52284,"corporation":false,"usgs":true,"family":"Walls","given":"Susan C.","affiliations":[],"preferred":false,"id":484481,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Barichivich, William J. 0000-0003-1103-6861 wbarichivich@usgs.gov","orcid":"https://orcid.org/0000-0003-1103-6861","contributorId":3697,"corporation":false,"usgs":true,"family":"Barichivich","given":"William","email":"wbarichivich@usgs.gov","middleInitial":"J.","affiliations":[{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true},{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true},{"id":13634,"text":"South Atlantic Water Science Center","active":true,"usgs":true}],"preferred":true,"id":484478,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Brown, Mary E. 0000-0002-5580-137X mbrown@usgs.gov","orcid":"https://orcid.org/0000-0002-5580-137X","contributorId":5688,"corporation":false,"usgs":true,"family":"Brown","given":"Mary","email":"mbrown@usgs.gov","middleInitial":"E.","affiliations":[{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true}],"preferred":true,"id":484479,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Scott, David E.","contributorId":15923,"corporation":false,"usgs":true,"family":"Scott","given":"David E.","affiliations":[],"preferred":false,"id":484480,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Hossack, Blake R. 0000-0001-7456-9564 blake_hossack@usgs.gov","orcid":"https://orcid.org/0000-0001-7456-9564","contributorId":1177,"corporation":false,"usgs":true,"family":"Hossack","given":"Blake","email":"blake_hossack@usgs.gov","middleInitial":"R.","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true},{"id":481,"text":"Northern Rocky Mountain Science Center","active":true,"usgs":true}],"preferred":true,"id":484477,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

This area consists of a west-dipping half graben in the northern Rio Grande rift that includes several intrabasinal grabens, faults, and folds. The Embudo–Santa Clara–Pajarito fault system, a collection of northeast- and north-striking faults in the center of the Española Basin, defines the western boundary of the half graben and was active throughout rifting. Throw rates near the middle of the fault system (i.e., the Santa Clara and north Pajarito faults) and associated hanging-wall tilt rates progressively increased during the middle Miocene. East of Española, hanging-wall tilt rates decreased after 10–12 Ma, coinciding with increased throw rates on the Cañada del Almagre fault. This fault may have temporarily shunted slip from the north Pajarito fault during ca. 8–11 Ma, resulting in lower strain rates on the Santa Clara fault. East of the Embudo–Santa Clara–Pajarito fault system, deformation of the southern Barrancos monocline and the Cañada Ancha graben peaked during the early–middle Miocene and effectively ceased by the late Pliocene.

The primary objectives were: (1) crop biophysical modeling through HNBs and HVIs, (2) accuracy assessment of crop type discrimination using Wilks' Lambda through a discriminant model, and (3) meta-analysis to select optimal HNBs and HVIs for applications related to agriculture. The study was conducted using two Earth Observing One (EO-1) Hyperion scenes and other surface hyperspectral data for the eight leading worldwide crops (wheat, corn, rice, barley, soybeans, pulses, cotton, and alfalfa) that occupy ~70% of all cropland areas globally. This study integrated data collected from multiple study areas in various agroecosystems of Africa, the Middle East, Central Asia, and India. Data were collected for the eight crop types in six distinct growth stages. These included (a) field spectroradiometer measurements (350-2500 nm) sampled at 1-nm discrete bandwidths, and (b) field biophysical variables (e.g., biomass, leaf area index) acquired to correspond with spectroradiometer measurements. The eight crops were described and classified using ~20 HNBs. The accuracy of classifying these 8 crops using HNBs was around 95%, which was ~ 25% better than the multi-spectral results possible from Landsat-7's Enhanced Thematic Mapper+ or EO-1's Advanced Land Imager. Further, based on this research and meta-analysis involving over 100 papers, the study established 33 optimal HNBs and an equal number of specific two-band normalized difference HVIs to best model and study specific biophysical and biochemical quantities of major agricultural crops of the world. Redundant bands identified in this study will help overcome the Hughes Phenomenon (or “the curse of high dimensionality”) in hyperspectral data for a particular application (e.g., biophysi- al characterization of crops). The findings of this study will make a significant contribution to future hyperspectral missions such as NASA's HyspIRI.","language":"English","publisher":"Institute of Electrical and Electronics Engineers","publisherLocation":"New York, NY","doi":"10.1109/JSTARS.2013.2252601","usgsCitation":"Thenkabail, P., Mariotto, I., Gumma, M., Middleton, E., Landis, D., and Huemmrich, K., 2013, Selection of hyperspectral narrowbands (HNBs) and composition of hyperspectral twoband vegetation indices (HVIs) for biophysical characterization and discrimination of crop types using field reflectance and Hyperion/EO-1 data: IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, v. 6, no. 2, p. 427-439, https://doi.org/10.1109/JSTARS.2013.2252601.","productDescription":"13 p.","startPage":"427","endPage":"439","numberOfPages":"13","ipdsId":"IP-037139","costCenters":[{"id":657,"text":"Western Geographic Science Center","active":true,"usgs":true},{"id":29789,"text":"John Wesley Powell Center for Analysis and Synthesis","active":true,"usgs":true}],"links":[{"id":473885,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"http://hdl.handle.net/11603/31506","text":"External Repository"},{"id":284275,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":284273,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1109/JSTARS.2013.2252601"}],"country":"India","otherGeospatial":"Africa;Central Asia;Middle East","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -32.7,-40.6 ], [ -32.7,46.9 ], [ 100.0,46.9 ], [ 100.0,-40.6 ], [ -32.7,-40.6 ] ] ] } } ] }","volume":"6","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd7255e4b0b29085108408","contributors":{"authors":[{"text":"Thenkabail, P.S.","contributorId":66071,"corporation":false,"usgs":true,"family":"Thenkabail","given":"P.S.","email":"","affiliations":[],"preferred":false,"id":491784,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Mariotto, I.","contributorId":47285,"corporation":false,"usgs":true,"family":"Mariotto","given":"I.","affiliations":[],"preferred":false,"id":491783,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Gumma, M.K.","contributorId":12286,"corporation":false,"usgs":true,"family":"Gumma","given":"M.K.","email":"","affiliations":[],"preferred":false,"id":491781,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Middleton, E.M.","contributorId":107656,"corporation":false,"usgs":true,"family":"Middleton","given":"E.M.","email":"","affiliations":[],"preferred":false,"id":491786,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Landis, D.R.","contributorId":25454,"corporation":false,"usgs":true,"family":"Landis","given":"D.R.","email":"","affiliations":[],"preferred":false,"id":491782,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Huemmrich, K.F.","contributorId":105632,"corporation":false,"usgs":true,"family":"Huemmrich","given":"K.F.","email":"","affiliations":[],"preferred":false,"id":491785,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

We detected the greenness trend of the grasslands in the plateau using Moderate Resolution Imaging Spectroradiometer data from 2000 to 2009. Weather station data were used to explore the climatic drivers for vegetation greenness variations. The results demonstrated that the region-wide averaged normalized difference vegetation index (NDVI) increased at a rate of 0.036  yr<sup>−1</sup>. Approximately 20% of the vegetation areas, which were primarily located in the northeastern plateau, exhibited significant NDVI increase trend (p-value <0.05). Only 4% of the vegetated area showed significant decrease trends, which were mostly in the central and southwestern plateau. A strong positive relationship between NDVI and precipitation, especially in the northeastern plateau, suggested that precipitation was a favorable factor for the grassland NDVI. Negative correlations between NDVI and temperature, especially in the southern plateau, indicated that higher temperature adversely affected the grassland growth. Although a warming climate was expected to be beneficial to the vegetation growth in cold regions, the grasslands in the central and southwestern plateau showed a decrease in trends influenced by increased temperature coupled with decreased precipitation.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Applied Remote Sensing","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"SPIE","doi":"10.1117/1.JRS.7.073572","usgsCitation":"Zhang, L., Guo, H., Ji, L., Lei, L., Wang, C., Yan, D., Li, B., and Li, J., 2013, Vegetation greenness trend (2000 to 2009) and the climate controls in the Qinghai-Tibetan Plateau: Journal of Applied Remote Sensing, v. 7, no. 1, 18 p., https://doi.org/10.1117/1.JRS.7.073572.","productDescription":"18 p.","numberOfPages":"18","onlineOnly":"Y","temporalStart":"2000-01-01","temporalEnd":"2009-12-31","ipdsId":"IP-032689","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":473886,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1117/1.jrs.7.073572","text":"Publisher Index Page"},{"id":280627,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":280626,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1117/1.JRS.7.073572"}],"country":"China","state":"Tibet;Qinghai","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 80.0,25.0 ], [ 80.0,40.0 ], [ 100.0,40.0 ], [ 100.0,25.0 ], [ 80.0,25.0 ] ] ] } } ] }","volume":"7","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd7b02e4b0b2908510ddb5","contributors":{"authors":[{"text":"Zhang, Li","contributorId":98139,"corporation":false,"usgs":true,"family":"Zhang","given":"Li","affiliations":[],"preferred":false,"id":487860,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Guo, Huadong","contributorId":21056,"corporation":false,"usgs":true,"family":"Guo","given":"Huadong","email":"","affiliations":[],"preferred":false,"id":487857,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Ji, Lei 0000-0002-6133-1036 lji@usgs.gov","orcid":"https://orcid.org/0000-0002-6133-1036","contributorId":2832,"corporation":false,"usgs":true,"family":"Ji","given":"Lei","email":"lji@usgs.gov","affiliations":[{"id":223,"text":"Earth Resources Observation and Science (EROS) Center (Geography)","active":false,"usgs":true}],"preferred":false,"id":487854,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Lei, Liping","contributorId":31299,"corporation":false,"usgs":true,"family":"Lei","given":"Liping","email":"","affiliations":[],"preferred":false,"id":487858,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Wang, Cuizhen","contributorId":16312,"corporation":false,"usgs":true,"family":"Wang","given":"Cuizhen","email":"","affiliations":[],"preferred":false,"id":487856,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Yan, Dongmei","contributorId":100736,"corporation":false,"usgs":true,"family":"Yan","given":"Dongmei","email":"","affiliations":[],"preferred":false,"id":487861,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Li, Bin","contributorId":47684,"corporation":false,"usgs":true,"family":"Li","given":"Bin","email":"","affiliations":[],"preferred":false,"id":487859,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Li, Jing","contributorId":9166,"corporation":false,"usgs":true,"family":"Li","given":"Jing","email":"","affiliations":[],"preferred":false,"id":487855,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

Hydraulic conductivity is typically measured by conducting aquifer tests or wellbore flow (WBF) logging. Of interest in our research is the use of proton nuclear magnetic resonance (NMR) logging to obtain information about water-filled porosity and pore space geometry, the combination of which can be used to estimate K. In this study, we acquired a suite of advanced geophysical logs, aquifer tests, WBF logs, and sidewall cores at the field site in Lexington, Nebraska, which is underlain by the High Plains aquifer. We first used two empirical equations developed for petroleum applications to predict K from NMR logging data: the Schlumberger Doll Research equation (K<sub>SDR</sub>) and the Timur-Coates equation (K<sub>T-C</sub>), with the standard empirical constants determined for consolidated materials. We upscaled our NMR-derived K estimates to the scale of the WBF-logging K(K<sub>WBF-logging</sub>) estimates for comparison. All the upscaled K<sub>T-C</sub> estimates were within an order of magnitude of K<sub>WBF-logging</sub> and all of the upscaled K<sub>SDR</sub> estimates were within 2 orders of magnitude of K<sub>WBF-logging</sub>. We optimized the fit between the upscaled NMR-derived K and KWBF-logging estimates to determine a set of site-specific empirical constants for the unconsolidated materials at our field site. We conclude that reliable estimates of K can be obtained from NMR logging data, thus providing an alternate method for obtaining estimates of K at high levels of vertical resolution.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Water Resources Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","doi":"10.1002/wrcr.20151","usgsCitation":"Dlubac, K., Knight, R., Song, Y., Bachman, N., Grau, B., Cannia, J., and Williams, J., 2013, Use of NMR logging to obtain estimates of hydraulic conductivity in the High Plains aquifer, Nebraska, USA: Water Resources Research, v. 49, no. 4, p. 1871-1886, https://doi.org/10.1002/wrcr.20151.","productDescription":"16 p.","startPage":"1871","endPage":"1886","numberOfPages":"16","ipdsId":"IP-041711","costCenters":[{"id":496,"text":"Office of Groundwater-Branch of Geophysics","active":false,"usgs":true}],"links":[{"id":473887,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1002/wrcr.20151","text":"Publisher Index Page"},{"id":281383,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":281332,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/wrcr.20151"}],"country":"United States","state":"Nebraska","city":"Lexington","otherGeospatial":"High Plains Aquifer","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -99.768037,40.743098 ], [ -99.768037,40.798141 ], [ -99.71096,40.798141 ], [ -99.71096,40.743098 ], [ -99.768037,40.743098 ] ] ] } } ] }","volume":"49","issue":"4","noUsgsAuthors":false,"publicationDate":"2013-04-15","publicationStatus":"PW","scienceBaseUri":"53cd7a7be4b0b2908510d886","contributors":{"authors":[{"text":"Dlubac, Katherine","contributorId":33218,"corporation":false,"usgs":true,"family":"Dlubac","given":"Katherine","email":"","affiliations":[],"preferred":false,"id":489034,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Knight, Rosemary","contributorId":84245,"corporation":false,"usgs":true,"family":"Knight","given":"Rosemary","email":"","affiliations":[],"preferred":false,"id":489037,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Song, Yi-Qiao","contributorId":60534,"corporation":false,"usgs":true,"family":"Song","given":"Yi-Qiao","email":"","affiliations":[],"preferred":false,"id":489036,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Bachman, Nate","contributorId":35639,"corporation":false,"usgs":true,"family":"Bachman","given":"Nate","email":"","affiliations":[],"preferred":false,"id":489035,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Grau, Ben","contributorId":96188,"corporation":false,"usgs":true,"family":"Grau","given":"Ben","email":"","affiliations":[],"preferred":false,"id":489038,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Cannia, Jim","contributorId":16746,"corporation":false,"usgs":true,"family":"Cannia","given":"Jim","email":"","affiliations":[],"preferred":false,"id":489032,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Williams, John","contributorId":23842,"corporation":false,"usgs":true,"family":"Williams","given":"John","email":"","affiliations":[],"preferred":false,"id":489033,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

Our analysis using three pseudo-invariant calibration sites in North America indicated that the reflectance time series are devoid of apparent spectral trends and their stability consistently is within 2.5-5 percent throughout most of the spectral range spanning the 12+ year data record. Using three vegetated sites instrumented with eddy covariance towers, the Hyperion reflectance time series were evaluated for their ability to determine important variables of ecosystem function. A number of narrowband and derivative vegetation indices (VI) closely described the seasonal profiles in vegetation function and ecosystem carbon exchange (e.g., net and gross ecosystem productivity) in three very different ecosystems, including a hardwood forest and tallgrass prairie in North America, and a Miombo woodland in Africa. Our results demonstrate the potential for scaling the carbon flux tower measurements to local and regional landscape levels. The VIs with stronger relationships to the CO<sub>2</sub> parameters were derived using continuous reflectance spectra and included wavelengths associated with chlorophyll content and/or chlorophyll fluorescence. Since these indices cannot be calculated from broadband multispectral instrument data, the opportunity to exploit these spectrometer-based VIs in the future will depend on the launch of satellites such as EnMAP and HyspIRI. This study highlights the practical utility of space-borne spectrometers for characterization of the spectral stability and uniformity of the calibration sites in support of sensor cross-comparisons, and demonstrates the potential of narrowband VIs to track and spatially extend ecosystem functional status as well as carbon processes measured at flux towers.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"IEEE Geoscience & Remote Sensing Society","doi":"10.1109/JSTARS.2013.2246139","usgsCitation":"Campbell, P., Middleton, E., Thome, K.J., Kokaly, R., Huemmrich, K., Novick, K., and Brunsell, N., 2013, EO-1 Hyperion reflectance time series at calibration and validation sites: stability and sensitivity to seasonal dynamics: IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, v. 6, no. 2, p. 276-290, https://doi.org/10.1109/JSTARS.2013.2246139.","productDescription":"15 p.","startPage":"276","endPage":"290","numberOfPages":"15","ipdsId":"IP-037418","costCenters":[{"id":218,"text":"Denver Federal Center","active":false,"usgs":true}],"links":[{"id":473888,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"http://hdl.handle.net/11603/28581","text":"External Repository"},{"id":276533,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":276369,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1109/JSTARS.2013.2246139"}],"country":"United States","state":"Nevada","otherGeospatial":"Frenchman Flat;Ivanpah Playa;Railroad Valley Playa","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -118.99,35.0 ], [ -118.99,39.84 ], [ -114.04,39.84 ], [ -114.04,35.0 ], [ -118.99,35.0 ] ] ] } } ] }","volume":"6","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"520a03e6e4b0026c2bc11aff","contributors":{"authors":[{"text":"Campbell, P.K.E.","contributorId":51640,"corporation":false,"usgs":true,"family":"Campbell","given":"P.K.E.","email":"","affiliations":[],"preferred":false,"id":482409,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Middleton, E.M.","contributorId":107656,"corporation":false,"usgs":true,"family":"Middleton","given":"E.M.","email":"","affiliations":[],"preferred":false,"id":482414,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Thome, K.

Seventy-two-hour postfertilization larvae were reared in untreated medium or in the presence of goitrogens (sodium perchlorate, 0.82 mM; methimazole, 0.15 and 0.3 mM) or thyroxine (1 and 10 nM) for 30 days. Thyrocyte height, gonadal sex and gonadal development were histologically determined at 45 and 60 days postfertilization (dpf). Thyrocyte hypertrophy, an index of hypothyroidism, was observed at 45 and 60 dpf in perchlorate-treated but only at 45 dpf in methimazole-treated fish. Similarly, gonadal sex ratios were biased toward ovaries relative to control animals at 45 and 60 dpf in perchlorate-treated fish but only at 45 dpf in methimazole-treated fish. Gonadal sex ratios were biased toward testes at 45 and 60 dpf in thyroxine-treated fish. Spermatogenesis was delayed in testes from goitrogen-treated fish at 60 dpf relative to control values, but was unaffected in testes from thyroxine-treated individuals. Oogenesis seemed to be nonspecifically delayed in all treatments relative to control at 60 dpf. This study confirmed the previously reported association between hypothyroid condition and ovarian-skewed ratios, and hyperthyroid condition and testicular-skewed ratios, and also showed that male pubertal development is specifically delayed by experimental hypothyroidism. The simultaneous recovery from the hypothyroid and ovary-inducing effects of methimazole by 60 dpf (27 days post-treatment) suggests that the ovary-skewing effect of goitrogens is reversible when thyroid conditions return to basal levels before developmental commitment of gonadal sex. Conversely, the masculinizing effect of hyperthyroidism seems to be stable and perhaps permanent.</p>","language":"English","publisher":"Academic Press","publisherLocation":"Orlando, FL","doi":"10.1016/j.ygcen.2012.12.018","usgsCitation":"Sharma, P., and Patino, R., 2013, Regulation of gonadal sex ratios and pubertal development by the thyroid endocrine system in zebrafish (<i>Danio rerio</i>): General and Comparative Endocrinology, v. 184, p. 111-119, https://doi.org/10.1016/j.ygcen.2012.12.018.","productDescription":"9 p.","startPage":"111","endPage":"119","numberOfPages":"9","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-038860","costCenters":[{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true}],"links":[{"id":302377,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"184","publishingServiceCenter":{"id":8,"text":"Raleigh PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"558e77b8e4b0b6d21dd65966","contributors":{"authors":[{"text":"Sharma, Prakash","contributorId":107435,"corporation":false,"usgs":true,"family":"Sharma","given":"Prakash","email":"","affiliations":[],"preferred":false,"id":556958,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Patino, Reynaldo 0000-0002-4831-8400 r.patino@usgs.gov","orcid":"https://orcid.org/0000-0002-4831-8400","contributorId":2311,"corporation":false,"usgs":true,"family":"Patino","given":"Reynaldo","email":"r.patino@usgs.gov","affiliations":[{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true}],"preferred":true,"id":556891,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

These rocks include tonalitic mylonite gneiss and mafic metaigneous rocks from the Chicken metamorphic complex and the Nasina and Fortymile River assemblages. Whole-rock trace-element data from the tonalitic gneiss, whose igneous protolith was dated by SHRIMP U–Pb zircon geochronology at 332.6 ± 5.6 Ma, indicate derivation from tholeiitic arc basalt. Whole-rock analyses of the mafic rocks suggest that greenschist-facies rocks from the Chicken metamorphic complex, a mafic metavolcanic rock from the Nasina assemblage, and an amphibolite from the Fortymile River assemblage formed as island-arc tholeiite in a back-arc setting; another Nasina assemblage greenschist has MORB geochemical characteristics, and another mafic metaigneous rock from the Fortymile River assemblage has geochemical characteristics of calc-alkaline basalt.

Projected warming over the 21st century is anticipated to shift the phase of precipitation toward more rain and less snow in mountainous areas in the Pacific Northwest, resulting in smaller winter snowpack and in a shift in the timing of runoff to earlier in the year. This will be accompanied by spatially variable changes in the timing of groundwater recharge. Analysis of historic climate and hydrologic data and modeling studies show that groundwater plays a key role in determining the response of stream systems to climate change. The spatial variability in the response of groundwater systems to climate change, particularly with regard to flow-system scale, however, has generally not been addressed in the literature. Here we simulate the hydrologic response to projected future climate to show that the response of groundwater systems can vary depending on the location and spatial scale of the flow systems and their aquifer characteristics. Mean annual recharge averaged over the basin does not change significantly between the 1980s and 2080s climate periods given the ensemble of global climate models and emission scenarios evaluated. There are, however, changes in the seasonality of groundwater recharge within the basin. Simulation results show that short-flow-path groundwater systems, such as those providing baseflow to many headwater streams, will likely have substantial changes in the timing of discharge in response changes in seasonality of recharge. Regional-scale aquifer systems with flow paths on the order of many tens of kilometers, in contrast, are much less affected by changes in seasonality of recharge. Flow systems at all spatial scales, however, are likely to reflect interannual changes in total recharge. These results provide insights into the possible impacts of climate change to other regional aquifer systems, and the streams they support, where discharge points represent a range of flow system scales.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Hydrology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.jhydrol.2013.01.019","usgsCitation":"Waibel, M.S., Gannett, M.W., Chang, H., and Hulbe, C.L., 2013, Spatial variability of the response to climate change in regional groundwater systems -- examples from simulations in the Deschutes Basin, Oregon: Journal of Hydrology, v. 486, p. 187-201, https://doi.org/10.1016/j.jhydrol.2013.01.019.","productDescription":"15 p.","startPage":"187","endPage":"201","numberOfPages":"15","ipdsId":"IP-040209","costCenters":[{"id":518,"text":"Oregon Water Science Center","active":true,"usgs":true}],"links":[{"id":279076,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":279075,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.jhydrol.2013.01.019"}],"country":"United States","state":"Oregon","otherGeospatial":"Deschutes Basin","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -122.5,43.0 ], [ -122.5,45.0 ], [ -120.5,45.0 ], [ -120.5,43.0 ], [ -122.5,43.0 ] ] ] } } ] }","volume":"486","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"528607a5e4b00926c21865bf","contributors":{"authors":[{"text":"Waibel, Michael S.","contributorId":19984,"corporation":false,"usgs":true,"family":"Waibel","given":"Michael","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":470001,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Gannett, Marshall W. 0000-0003-2498-2427 mgannett@usgs.gov","orcid":"https://orcid.org/0000-0003-2498-2427","contributorId":2942,"corporation":false,"usgs":true,"family":"Gannett","given":"Marshall","email":"mgannett@usgs.gov","middleInitial":"W.","affiliations":[{"id":518,"text":"Oregon Water Science Center","active":true,"usgs":true}],"preferred":true,"id":469999,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Chang, Heejun","contributorId":14705,"corporation":false,"usgs":true,"family":"Chang","given":"Heejun","email":"","affiliations":[],"preferred":false,"id":470000,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hulbe, Christina L.","contributorId":93371,"corporation":false,"usgs":true,"family":"Hulbe","given":"Christina","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":470002,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Sago pondweed (<i>Stuckenia pectinata</i>) was associated with lower average water depths than water milfoil (<i>Myriophyllum sibiricum</i>). We detected a nonlinear relationship when average water depths were used to predict percent cover in <i>S. pectinata</i>, with depths of 30–40 cm, producing the highest predicted average percent cover of <i>S. pectinata</i>; higher and lower depths resulted in lower percent cover predictions. For <i>M. sibiricum</i>, higher water depths were monotonically associated with higher average percent cover. To foster more <i>S. pectinata</i> and less <i>M. sibiricum</i>, managers might employ water control structures to reduce water depths below 1 m, using both temporary drawdowns and average depths of 30–40 cm. Other species responded less markedly to water depth variation. Should decreased water depths become more common, these results suggest an increase in <i>S. pectinata</i> and a decrease in <i>M. sibiricum</i>.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecohydrology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","doi":"10.1002/eco.1252","usgsCitation":"Sharp, J.L., Sodja, R.S., Greenwood, M., Rosenberry, D.O., and Warren, J.M., 2013, Statistical classification of vegetation and water depths in montane wetlands: Ecohydrology, v. 6, no. 2, p. 173-181, https://doi.org/10.1002/eco.1252.","productDescription":"9 p.","startPage":"173","endPage":"181","numberOfPages":"9","ipdsId":"IP-026068","costCenters":[{"id":481,"text":"Northern Rocky Mountain Science Center","active":true,"usgs":true}],"links":[{"id":275390,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":275388,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/eco.1252"}],"country":"United States","volume":"6","issue":"2","noUsgsAuthors":false,"publicationDate":"2012-02-28","publicationStatus":"PW","scienceBaseUri":"51f25423e4b0279fe2e1c036","contributors":{"authors":[{"text":"Sharp, Julia L.","contributorId":33204,"corporation":false,"usgs":false,"family":"Sharp","given":"Julia","email":"","middleInitial":"L.","affiliations":[{"id":33234,"text":"Clemson University, Clemson, SC","active":true,"usgs":false}],"preferred":false,"id":479591,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sodja, Richard S.","contributorId":71856,"corporation":false,"usgs":true,"family":"Sodja","given":"Richard","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":479592,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Greenwood, Mark","contributorId":91387,"corporation":false,"usgs":true,"family":"Greenwood","given":"Mark","affiliations":[],"preferred":false,"id":479593,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Rosenberry, Donald O. 0000-0003-0681-5641 rosenber@usgs.gov","orcid":"https://orcid.org/0000-0003-0681-5641","contributorId":1312,"corporation":false,"usgs":true,"family":"Rosenberry","given":"Donald","email":"rosenber@usgs.gov","middleInitial":"O.","affiliations":[{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true},{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"preferred":true,"id":479589,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Warren, Jeffrey M.","contributorId":16297,"corporation":false,"usgs":true,"family":"Warren","given":"Jeffrey","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":479590,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Probabilistic seismic hazard analysis (PSHA) estimates the ground-motion hazard by incorporating the aleatory uncertainties in all earthquake scenarios and resulting ground motions, as well as the epistemic uncertainties in ground-motion prediction models (GMPMs) and seismic source models. Typical CS calculations to date are produced for a single earthquake scenario using a single GMPM, but more precise use requires consideration of at least multiple causal earthquakes and multiple GMPMs that are often considered in a PSHA computation. This paper presents the mathematics underlying these more precise CS calculations. Despite requiring more effort to compute than approximate calculations using a single causal earthquake and GMPM, the proposed approach produces an exact output that has a theoretical basis. To demonstrate the results of this approach and compare the exact and approximate calculations, several example calculations are performed for real sites in the western United States. The results also provide some insights regarding the circumstances under which approximate results are likely to closely match more exact results. To facilitate these more precise calculations for real applications, the exact CS calculations can now be performed for real sites in the United States using new deaggregation features in the U.S. Geological Survey hazard mapping tools. Details regarding this implementation are discussed in this paper.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Bulletin of the Seismological Society of America","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Seismological Society of America","publisherLocation":"Stanford, CA","doi":"10.1785/0120110293","usgsCitation":"Lin, T., Harmsen, S., Baker, J., and Luco, N., 2013, Conditional spectrum computation incorporating multiple causal earthquakes and ground-motion prediction models: Bulletin of the Seismological Society of America, v. 103, no. 2A, p. 1103-1116, https://doi.org/10.1785/0120110293.","productDescription":"14 p.","startPage":"1103","endPage":"1116","numberOfPages":"14","costCenters":[],"links":[{"id":291132,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":291131,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1785/0120110293"}],"volume":"103","issue":"2A","noUsgsAuthors":false,"publicationDate":"2013-03-21","publicationStatus":"PW","scienceBaseUri":"57f7f324e4b0bc0bec0a07e1","contributors":{"authors":[{"text":"Lin, Ting","contributorId":12384,"corporation":false,"usgs":true,"family":"Lin","given":"Ting","email":"","affiliations":[],"preferred":false,"id":496682,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Harmsen, Stephen C. harmsen@usgs.gov","contributorId":1795,"corporation":false,"usgs":true,"family":"Harmsen","given":"Stephen C.","email":"harmsen@usgs.gov","affiliations":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":false,"id":496681,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Baker, Jack W.","contributorId":62113,"corporation":false,"usgs":false,"family":"Baker","given":"Jack W.","affiliations":[{"id":6986,"text":"Stanford University","active":true,"usgs":false}],"preferred":false,"id":496683,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Luco, Nicolas 0000-0002-5763-9847 nluco@usgs.gov","orcid":"https://orcid.org/0000-0002-5763-9847","contributorId":1188,"corporation":false,"usgs":true,"family":"Luco","given":"Nicolas","email":"nluco@usgs.gov","affiliations":[{"id":234,"text":"Earthquake Hazards Program","active":true,"usgs":true}],"preferred":false,"id":496680,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Rain falling on this ash blanket within days of cessation of major explosive activity generated a hyperconcentrated-flow lahar, followed closely by a complex, multi-day, muddy flood (streamflow bordering on dilute hyperconcentrated flow). Sediment mobilized in this lahar-flood event filled the Chaitén River channel with up to 7 m of sediment, buried the town of Chaitén (10 km downstream of the volcano) in up to 3 m of sediment, and caused the lower 3 km of the channel to avulse through the town. Although neither the nature nor rate of the sedimentation response is unprecedented, they are unusual in several ways: (1) Nearly 70 percent of the aggradation (almost 5 m) in the 50–70-m-wide Chaitén River channel was caused by a lahar, triggered by an estimated 20 mm of rainfall over a span of about 24 h. An additional 2 m of aggradation occurred in the next 24–36 h. (2) Direct damage to the town was accomplished by the sediment-laden water-flood phase of the lahar-flood event, not the lahar phase. (3) The volume of sediment eroded from hillslopes and delivered to the Chaitén River channel was at least 3–8 × 10<sup>6</sup> m<sup>3</sup>—roughly 15–40 % of the minimum tephra volume that mantled the Chaitén River drainage basin. (4) The acute sedimentation response to rainfall appears to have been due to the thickness and fineness of the ash blanket (inhibiting infiltration of rain) and the steepness of the basin’s hillslopes. Other possible factors such as the prior formation of an ash crust, development of a hydrophobic surface layer, or large-scale destruction of rain-intercepting vegetation did not play a role.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Bulletin of Volcanology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer","doi":"10.1007/s00445-013-0723-4","usgsCitation":"Pierson, T.C., Major, J.J., Amigo, Á., and Moreno, H., 2013, Acute sedimentation response to rainfall following the explosive phase of the 2008-2009 eruption of Chaitén volcano, Chile: Bulletin of Volcanology, v. 75, no. 723, 17 p., https://doi.org/10.1007/s00445-013-0723-4.","productDescription":"17 p.","numberOfPages":"17","onlineOnly":"Y","ipdsId":"IP-044711","costCenters":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":473889,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1007/s00445-013-0723-4","text":"Publisher Index Page"},{"id":281555,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":281406,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s00445-013-0723-4"}],"country":"Chile","otherGeospatial":"Chait�n Caldera","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -74.0,-44.0 ], [ -74.0,-41.0 ], [ -72.0,-41.0 ], [ -72.0,-44.0 ], [ -74.0,-44.0 ] ] ] } } ] }","volume":"75","issue":"723","noUsgsAuthors":false,"publicationDate":"2013-04-28","publicationStatus":"PW","scienceBaseUri":"53cd4b27e4b0b290850f0308","contributors":{"authors":[{"text":"Pierson, Thomas C. 0000-0001-9002-4273 tpierson@usgs.gov","orcid":"https://orcid.org/0000-0001-9002-4273","contributorId":2498,"corporation":false,"usgs":true,"family":"Pierson","given":"Thomas","email":"tpierson@usgs.gov","middleInitial":"C.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":489145,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Major, Jon J. 0000-0003-2449-4466 jjmajor@usgs.gov","orcid":"https://orcid.org/0000-0003-2449-4466","contributorId":439,"corporation":false,"usgs":true,"family":"Major","given":"Jon","email":"jjmajor@usgs.gov","middleInitial":"J.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":489144,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Amigo, Álvaro","contributorId":89054,"corporation":false,"usgs":true,"family":"Amigo","given":"Álvaro","affiliations":[],"preferred":false,"id":489147,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Moreno, Hugo","contributorId":20232,"corporation":false,"usgs":true,"family":"Moreno","given":"Hugo","email":"","affiliations":[],"preferred":false,"id":489146,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

In Kentucky, this includes mountainous regions, karstic plateau, and alluvial plains. Soils data are critical because they quantify the space to store water, as well as how water moves through the soil to the stream during storm events. We compared how the model performs using two different sources of soils data--Soil Survey Geographic Database (SSURGO) and State Soil Geographic Database laboratory data (STATSGO)--for 21 basins ranging in size from 17 to 1564 km<sup>2</sup>. Model results were consistently better when SSURGO data were used, likely due to the higher field capacity, porosity, and available-water holding capacity, which cause the model to store more soil-water in the landscape and improve streamflow estimates for both low- and high-flow conditions. In addition, there were significant differences in the conductivity multiplier and scaling parameter values that describe how water moves vertically and laterally, respectively, as quantified by TOPMODEL. We also evaluated whether partitioning areas that drain to streams via sinkholes in karstic basins as separate hydrologic modeling units (HMUs) improved model performance. There were significant differences between HMUs in properties that control soil-water storage in the model, although the effect of partitioning these HMUs on streamflow simulation was inconclusive.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Soil Science Society of America Journal","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Soil Science Society of America","doi":"10.2136/sssaj2012.0069","usgsCitation":"Williamson, T., Taylor, C.J., and Newson, J.K., 2013, Significance of exchanging SSURGO and STATSGO data when modeling hydrology in diverse physiographic terranes: Soil Science Society of America Journal, v. 77, no. 3, p. 877-889, https://doi.org/10.2136/sssaj2012.0069.","productDescription":"13 p.","startPage":"877","endPage":"889","numberOfPages":"13","ipdsId":"IP-036109","costCenters":[{"id":354,"text":"Kentucky Water Science Center","active":true,"usgs":true}],"links":[{"id":275377,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":275376,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2136/sssaj2012.0069"}],"country":"United States","state":"Kentucky","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -89.5715,36.4972 ], [ -89.5715,39.1475 ], [ -81.965,39.1475 ], [ -81.965,36.4972 ], [ -89.5715,36.4972 ] ] ] } } ] }","volume":"77","issue":"3","noUsgsAuthors":false,"publicationDate":"2013-04-19","publicationStatus":"PW","scienceBaseUri":"51f25422e4b0279fe2e1c026","contributors":{"authors":[{"text":"Williamson, Tanja N. tnwillia@usgs.gov","contributorId":452,"corporation":false,"usgs":true,"family":"Williamson","given":"Tanja N.","email":"tnwillia@usgs.gov","affiliations":[{"id":354,"text":"Kentucky Water Science Center","active":true,"usgs":true}],"preferred":false,"id":479605,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Taylor, Charles J.","contributorId":93100,"corporation":false,"usgs":true,"family":"Taylor","given":"Charles","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":479607,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Newson, Jeremy K. jknewson@usgs.gov","contributorId":4159,"corporation":false,"usgs":true,"family":"Newson","given":"Jeremy","email":"jknewson@usgs.gov","middleInitial":"K.","affiliations":[{"id":677,"text":"Wisconsin Water Science Center","active":true,"usgs":true}],"preferred":false,"id":479606,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The of dust will be greatest where the geochemical composition of dust is distinct from local sources of soil parent material. In this study the influence of dust accretion on soil geochemistry is quantified for two different soils from the San Juan Mountains of southwestern Colorado, USA. At both study sites, dust is enriched in several trace elements relative to local rock, especially Cd, Cu, Pb, and Zn. Mass-balance calculations that do not explicitly account for dust inputs indicate the accumulation of some elements in soil beyond what can be explained by weathering of local rock. Most observed elemental enrichments are explained by accounting for the long-term accretion of dust, based on modern isotopic and geochemical estimates. One notable exception is Pb, which based on mass-balance calculations and isotopic measurements may have an additional source at one of the study sites. These results suggest that dust is a major factor influencing the development of soil in these settings and is also an important control of soil weathering fluxes. After accounting for dust inputs in mass-balance calculations, Si weathering fluxes from San Juan Mountain soils are within the range observed for other temperate systems. Comparing dust inputs with mass-balanced based flux estimates suggests dust could account for as much as 50–80% of total long-term chemical weathering fluxes. These results support the notion that dust inputs may sustain chemical weathering fluxes even in relatively young continental settings. Given the widespread input of far-traveled dust, the weathering of dust is likely and important and underappreciated aspect of the global weathering engine.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geochimica et Cosmochimica Acta","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.gca.2012.12.023","usgsCitation":"Lawrence, C., Reynolds, R.L., Kettterer, M.E., and Neff, J.C., 2013, Aeolian controls of soil geochemistry and weathering fluxes in high-elevation ecosystems of the Rocky Mountains, Colorado: Geochimica et Cosmochimica Acta, v. 107, p. 27-46, https://doi.org/10.1016/j.gca.2012.12.023.","productDescription":"20 p.","startPage":"27","endPage":"46","numberOfPages":"20","ipdsId":"IP-044155","costCenters":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"links":[{"id":279308,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":279307,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.gca.2012.12.023"}],"country":"United States","state":"Colorado","otherGeospatial":"San Juan Mountains","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -108.86,37.12 ], [ -108.86,38.56 ], [ -107.16,38.56 ], [ -107.16,37.12 ], [ -108.86,37.12 ] ] ] } } ] }","volume":"107","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"528f53ede4b0660d392bed86","contributors":{"authors":[{"text":"Lawrence, Corey R. clawrence@usgs.gov","contributorId":4478,"corporation":false,"usgs":true,"family":"Lawrence","given":"Corey R.","email":"clawrence@usgs.gov","affiliations":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"preferred":false,"id":486600,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Reynolds, Richard L. 0000-0002-4572-2942 rreynolds@usgs.gov","orcid":"https://orcid.org/0000-0002-4572-2942","contributorId":441,"corporation":false,"usgs":true,"family":"Reynolds","given":"Richard","email":"rreynolds@usgs.gov","middleInitial":"L.","affiliations":[{"id":271,"text":"Federal Center","active":false,"usgs":true}],"preferred":true,"id":486599,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kettterer, Michael E.","contributorId":13518,"corporation":false,"usgs":true,"family":"Kettterer","given":"Michael","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":486601,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Neff, Jason C.","contributorId":34813,"corporation":false,"usgs":true,"family":"Neff","given":"Jason","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":486602,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Several different techniques are described to estimate the parameters for a suite of candidate probability models. The techniques, previously developed for analyzing paleoseismic data, include maximum likelihood and Type II (Bayesian) maximum likelihood methods derived from renewal process theory and Monte Carlo methods. The estimated mean return time from these methods, unlike estimates from a simple arithmetic mean of the center age dates and standard likelihood methods, includes the effects of age-dating uncertainty and of open time intervals before the first and after the last event. The likelihood techniques are evaluated using Akaike’s Information Criterion (AIC) and Akaike’s Bayesian Information Criterion (ABIC) to select the optimal model. The techniques are applied to mass transport deposits recorded in two Integrated Ocean Drilling Program (IODP) drill sites located in the Ursa Basin, northern Gulf of Mexico. Dates of the deposits were constrained by regional bio- and magnetostratigraphy from a previous study. Results of the analysis indicate that submarine mass failures in this location occur primarily according to a Poisson process in which failures are independent and return times follow an exponential distribution. However, some of the model results suggest that submarine mass failures may occur quasiperiodically at one of the sites (U1324). The suite of techniques described in this study provides quantitative probability estimates of submarine mass failure occurrence, for any number of deposits and age uncertainty distributions.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geosphere","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Geological Society of America","doi":"10.1130/GES00829.1","usgsCitation":"Geist, E.L., Chaytor, J., Parsons, T.E., and ten Brink, U., 2013, Estimation of submarine mass failure probability from a sequence of deposits with age dates: Geosphere, v. 9, no. 2, p. 287-298, https://doi.org/10.1130/GES00829.1.","productDescription":"12 p.","startPage":"287","endPage":"298","numberOfPages":"12","ipdsId":"IP-043363","costCenters":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":473892,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1130/ges00829.1","text":"Publisher Index Page"},{"id":277441,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":277437,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1130/GES00829.1"}],"otherGeospatial":"Ursa Basin","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -89.25,28.0 ], [ -89.25,28.166667 ], [ -88.916667,28.166667 ], [ -88.916667,28.0 ], [ -89.25,28.0 ] ] ] } } ] }","volume":"9","issue":"2","noUsgsAuthors":false,"publicationDate":"2013-03-18","publicationStatus":"PW","scienceBaseUri":"52303f62e4b04b8e63a20631","contributors":{"authors":[{"text":"Geist, Eric L. 0000-0003-0611-1150 egeist@usgs.gov","orcid":"https://orcid.org/0000-0003-0611-1150","contributorId":1956,"corporation":false,"usgs":true,"family":"Geist","given":"Eric","email":"egeist@usgs.gov","middleInitial":"L.","affiliations":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true},{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true}],"preferred":true,"id":483723,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Chaytor, Jason D.","contributorId":88637,"corporation":false,"usgs":true,"family":"Chaytor","given":"Jason D.","affiliations":[],"preferred":false,"id":483726,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Parsons, Thomas E. 0000-0002-0582-4338 tparsons@usgs.gov","orcid":"https://orcid.org/0000-0002-0582-4338","contributorId":2314,"corporation":false,"usgs":true,"family":"Parsons","given":"Thomas","email":"tparsons@usgs.gov","middleInitial":"E.","affiliations":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":true,"id":483724,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"ten Brink, Uri S. 0000-0001-6858-3001 utenbrink@usgs.gov","orcid":"https://orcid.org/0000-0001-6858-3001","contributorId":127560,"corporation":false,"usgs":true,"family":"ten Brink","given":"Uri S.","email":"utenbrink@usgs.gov","affiliations":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true},{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true}],"preferred":false,"id":483725,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}
