It was designed to be reproducible and testable. Our preferred hybrid forecast is a log–linear blend of two parent forecasts based on the Global Centroid Moment Tensor (CMT) catalog (smoothing 4602 m≥5.767 shallow earthquakes, 1977–2004) and the Global Strain Rate Map version 2.1 (smoothing 22,415 Global Positioning System velocities), optimized to best forecast the 2005–2012 Global CMT catalog. Strain rate is a proxy for fault stress accumulation, and earthquakes indicate stress release, so a multiplicative blend is desirable, capturing the strengths of both approaches. This preferred hybrid forecast outperforms its seismicity and strain‐rate parents; the chance that this improvement stems from random seismicity fluctuations is less than 1%. The preferred hybrid is also tested against the independent parts of the International Seismological Centre‐Global Earthquake Model catalog (m≥6.8 during 1918–1976) with similar success. GEAR1 is an update of this preferred hybrid. Comparing GEAR1 to the Uniform California Earthquake Rupture Forecast Version 3 (UCERF3), net earthquake rates agree within 4% at m≥5.8 and at m≥7.0. The spatial distribution of UCERF3 epicentroids most resembles GEAR1 after UCERF3 is smoothed with a 30 km kernel. Because UCERF3 has been constructed to derive useful information from fault geometry, slip rates, paleoseismic data, and enhanced seismic catalogs (not used in our model), this is encouraging. To build parametric catastrophe bonds from GEAR1, one could calculate the magnitude for which there is a 1% (or any) annual probability of occurrence in local regions.","language":"English","publisher":"Seismological Society of America","doi":"10.1785/0120150058","usgsCitation":"Bird, P., Jackson, D.D., Kagan, Y.Y., Kreemer, C., and Stein, R., 2015, GEAR1: A Global Earthquake Activity Rate model constructed from geodetic strain rates and smoothed seismicity: Bulletin of the Seismological Society of America, v. 105, no. 5, p. 2538-2554, https://doi.org/10.1785/0120150058.","productDescription":"17 p.","startPage":"2538","endPage":"2554","ipdsId":"IP-063010","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":355413,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"105","issue":"5","publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationDate":"2015-09-01","publicationStatus":"PW","scienceBaseUri":"5b46e9b6e4b060350a15d348","contributors":{"authors":[{"text":"Bird, Peter","contributorId":195948,"corporation":false,"usgs":false,"family":"Bird","given":"Peter","email":"","affiliations":[],"preferred":false,"id":739277,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Jackson, David D.","contributorId":94762,"corporation":false,"usgs":true,"family":"Jackson","given":"David","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":739278,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kagan, Yan Y.","contributorId":206059,"corporation":false,"usgs":false,"family":"Kagan","given":"Yan","email":"","middleInitial":"Y.","affiliations":[{"id":13399,"text":"UCLA","active":true,"usgs":false}],"preferred":false,"id":739279,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Kreemer, Corne","contributorId":15902,"corporation":false,"usgs":true,"family":"Kreemer","given":"Corne","email":"","affiliations":[],"preferred":false,"id":739280,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Stein, Ross 0000-0001-7586-3933 rstein@usgs.gov","orcid":"https://orcid.org/0000-0001-7586-3933","contributorId":206056,"corporation":false,"usgs":true,"family":"Stein","given":"Ross","email":"rstein@usgs.gov","affiliations":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"preferred":true,"id":739276,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

We have gathered all available historical reports on Kawah Ijen’s activity since 1770 with the purpose of reviewing the temporal evolution of its activity. Most of these observations and studies have been conducted from a geochemical perspective and in punctuated scientific campaigns. Starting in 1991, the seismic activity and a set of volcanic lake parameters began to be weekly available. We present a database of those measurements that, combined with historical reports, allow us to review each eruption/unrest that occurred during the last two centuries. As of 2010, the volcanic activity is monitored by a new multi-disciplinary network, including digital seismic stations, and lake level and temperature measurements. This detailed monitoring provides an opportunity for better classifying seismic events and forecasting volcanic unrest at Kawah Ijen, but only with the understanding of the characteristics of this volcanic system gained from the historical review presented here.","language":"English","publisher":"Springer","doi":"10.1007/s00445-014-0885-8","usgsCitation":"Caudron, C., Syahbana, D.K., Lecocq, T., van Hinsberg, V., McCausland, W., Triantafyllou, A., Camelbeeck, T., Bernard, A., and , S., 2015, Kawah Ijen volcanic activity: A review: Bulletin of Volcanology, v. 77, Article 16; 39 p., https://doi.org/10.1007/s00445-014-0885-8.","productDescription":"Article 16; 39 p.","ipdsId":"IP-060477","costCenters":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":471552,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1007/s00445-014-0885-8","text":"Publisher Index Page"},{"id":344231,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Indonesia","otherGeospatial":"Kawah Ijen","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              109.00634765625,\n              -9.156332560046778\n            ],\n            [\n              114.98291015625,\n              -9.156332560046778\n            ],\n            [\n              114.98291015625,\n              -6.124169589851178\n            ],\n            [\n              109.00634765625,\n              -6.124169589851178\n            ],\n            [\n              109.00634765625,\n              -9.156332560046778\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"77","publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationDate":"2015-02-07","publicationStatus":"PW","scienceBaseUri":"59770751e4b0ec1a48889f84","contributors":{"authors":[{"text":"Caudron, Corentin","contributorId":194972,"corporation":false,"usgs":false,"family":"Caudron","given":"Corentin","affiliations":[],"preferred":false,"id":705999,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Syahbana, Devy Kamil","contributorId":194973,"corporation":false,"usgs":false,"family":"Syahbana","given":"Devy","email":"","middleInitial":"Kamil","affiliations":[],"preferred":false,"id":706000,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Lecocq, Thomas","contributorId":141030,"corporation":false,"usgs":false,"family":"Lecocq","given":"Thomas","email":"","affiliations":[{"id":13659,"text":"Royal Observatory of Belgium","active":true,"usgs":false}],"preferred":false,"id":706001,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"van Hinsberg, Vincent","contributorId":194974,"corporation":false,"usgs":false,"family":"van Hinsberg","given":"Vincent","affiliations":[],"preferred":false,"id":706002,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"McCausland, Wendy wmccausland@usgs.gov","contributorId":5497,"corporation":false,"usgs":true,"family":"McCausland","given":"Wendy","email":"wmccausland@usgs.gov","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":705998,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Triantafyllou, Antoine","contributorId":194975,"corporation":false,"usgs":false,"family":"Triantafyllou","given":"Antoine","email":"","affiliations":[],"preferred":false,"id":706003,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Camelbeeck, Thierry","contributorId":141031,"corporation":false,"usgs":false,"family":"Camelbeeck","given":"Thierry","email":"","affiliations":[{"id":13659,"text":"Royal Observatory of Belgium","active":true,"usgs":false}],"preferred":false,"id":706004,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Bernard, Alain","contributorId":194976,"corporation":false,"usgs":false,"family":"Bernard","given":"Alain","email":"","affiliations":[],"preferred":false,"id":706005,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":" Surono","contributorId":149582,"corporation":false,"usgs":false,"given":"Surono","email":"","affiliations":[],"preferred":false,"id":706006,"contributorType":{"id":1,"text":"Authors"},"rank":9}]}}

S. Geological Survey's “Did you feel it?” (DYFI) system now provides excellent characterization of shaking intensities caused by induced and tectonic earthquakes. Seventeen CEUS events are considered between 2013 and 2015. It is shown that for 15 events, observed intensities at epicentral distances greater than ≈ 10 km are lower than expected given a published intensity-prediction equation for the region. Using simple published relations among intensity, magnitude, and stress drop, the results suggest that 15 of the 17 events have low stress drop. For those 15 events, intensities within ≈ 10-km epicentral distance are closer to predicted values, which can be explained as a consequence of relatively shallow source depths. The results suggest that those 15 events, most of which occurred in areas where induced earthquakes have occurred previously, were likely induced. Although moderate injection-induced earthquakes in the central and eastern United States will be felt widely because of low regional attenuation, the damage from shallow earthquakes induced by injection will be more localized to event epicenters than shaking tectonic earthquakes, which tend to be somewhat deeper. Within approximately 10 km of the epicenter, intensities are generally commensurate with predicted levels expected for the event magnitude.</span><br></p>","language":"English","publisher":"Society of Exploration Geophysicists","doi":"10.1190/tle34060690.1","usgsCitation":"Hough, S.E., 2015, Shaking intensity from injection-induced versus tectonic earthquakes in the central-eastern United States: The Leading Edge, v. 34, no. 6, p. 690-697, https://doi.org/10.1190/tle34060690.1.","productDescription":"6 p.","startPage":"690","endPage":"697","ipdsId":"IP-063054","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":344018,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -79.89257812499999,\n              41.178653972331674\n            ],\n            [\n              -106.171875,\n              44.77793589631623\n            ],\n            [\n              -106.12792968749999,\n              42.97250158602597\n            ],\n            [\n              -104.94140625,\n              32.76880048488168\n            ],\n            [\n              -81.5185546875,\n              33.358061612778876\n            ],\n            [\n              -79.89257812499999,\n              41.178653972331674\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"34","issue":"6","publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"59706fb8e4b0d1f9f065a8b0","contributors":{"authors":[{"text":"Hough, Susan E. 0000-0002-5980-2986 hough@usgs.gov","orcid":"https://orcid.org/0000-0002-5980-2986","contributorId":587,"corporation":false,"usgs":true,"family":"Hough","given":"Susan","email":"hough@usgs.gov","middleInitial":"E.","affiliations":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"preferred":true,"id":705454,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Habitat requirements of wide-ranging species often vary spatially, but quantitative assessment of variation among replicated studies at multiple sites is rare. We investigated patterns of space use for 10 populations of two closely related species of prairie grouse: Greater Prairie-Chickens (</span><i>Tympanuchus cupido</i><span>) and Lesser Prairie-Chickens (</span><i>T. pallidicinctus</i><span>). Prairie chickens require large, intact tracts of native grasslands, and are umbrella species for conservation of prairie ecosystems in North America. We used resource utilization functions to investigate space use by female prairie chickens during the 6-month breeding season from March through August in relation to lek sites, habitat conditions, and anthropogenic development. Our analysis included data from 382 radio-marked individuals across a major portion of the extant range. Our project is a unique opportunity to study comparative space use of prairie chickens, and we employed standardized methods that facilitated direct comparisons across an ecological gradient of study sites. Median home range size of females varied ~10-fold across 10 sites (3.6–36.7 km</span><sup>2</sup><span>), and home ranges tended to be larger at sites with higher annual precipitation. Proximity to lek sites was a strong and consistent predictor of space use for female prairie chickens at all 10 sites. The relative importance of other predictors of space use varied among sites, indicating that generalized habitat management guidelines may not be appropriate for these two species. Prairie chickens actively selected for prairie habitats, even at sites where ~90% of the land cover within the study area was prairie. A majority of the females monitored in our study (&gt;95%) had activity centers within 5 km of leks, suggesting that conservation efforts can be effectively concentrated near active lek sites. Our data on female space use suggest that lek surveys of male prairie chickens can indirectly assess habitat suitability for females during the breeding season. Lek monitoring and surveys for new leks provide information on population trends, but can also guide management actions aimed at improving nesting and brood-rearing habitats.</span></p>","language":"English","publisher":"Ecological Society of America","doi":"10.1890/ES14-00536.1","usgsCitation":"Winder, V.L., Carrlson, K.M., Gregory, A.J., Hagen, C.A., Haukos,

These stock assessments provide data on the status and trends of prey fish that are consumed by important commercial and recreational fishes. Although all these annual surveys are conducted using\nbottom trawls, they differ among the lakes in the proportion of the lake covered, seasonal timing, trawl gear used, and the manner in which the trawl is towed (across or along bottom contours). Because each assessment is unique, population indices were standardized to the highest value for a time series within each lake for the following prey species: Cisco (Coregonus artedi), Bloater (C. hoyi), Rainbow Smelt (Osmerus mordax), Alewife (Alosa pseudoharengus), and Round Goby (Neogobius melanostomus). In this report, standardized indices are presented in graphical form along with synopses to provide a short, informal cross-basin summary of the status and trends of principal prey fishes.","largerWorkTitle":"Compiled reports to the Great Lakes Fishery Commission of the Annual Bottom Trawl and Acoustics Surveys, 2014","language":"English","publisher":"Great Lakes Fishery Commission","collaboration":"Great Lakes Fishery Commission, Ontario Ministry of Natural Resources, Ohio Department of Natural Resources, New York State Department of Environmental Conservation, Pennsylvania Fish and Boat Commission","usgsCitation":"Gorman, O.T., and Weidel, B., 2015, Great Lakes prey fish populations: A cross-basin Overview of status and trends based on bottom trawl surveys, 1978-2014, 10 p.","productDescription":"10 p.","startPage":"96","endPage":"105","ipdsId":"IP-063855","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":340433,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":313014,"type":{"id":15,"text":"Index Page"},"url":"https://www.glfc.org/lakecom/common_docs/Compiled%20Reports%20from%20USGS%202015.pdf"}],"publishingServiceCenter":{"id":6,"text":"Columbus PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5901b1bce4b0c2e071a99ba2","contributors":{"authors":[{"text":"Gorman, Owen T. 0000-0003-0451-110X otgorman@usgs.gov","orcid":"https://orcid.org/0000-0003-0451-110X","contributorId":2888,"corporation":false,"usgs":true,"family":"Gorman","given":"Owen","email":"otgorman@usgs.gov","middleInitial":"T.","affiliations":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"preferred":true,"id":583726,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Weidel, Brian 0000-0001-6095-2773 bweidel@usgs.gov","orcid":"https://orcid.org/0000-0001-6095-2773","contributorId":2485,"corporation":false,"usgs":true,"family":"Weidel","given":"Brian","email":"bweidel@usgs.gov","affiliations":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"preferred":true,"id":583727,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

These scales range from smaller than the sediment grain scale (less than 10 μm) to as large as the field scale which can extend over several kilometers. The key processes that need to be considered include both geochemical reactions in solution and at sediment surfaces as well as physical transport processes including advection, dispersion, and pore-scale diffusion. The research summarized in this report includes both experimental and modeling results in batch, column and tracer tests. The objectives of this research were to: (1) quantify the rates of U(VI) desorption from sediments acquired from a uranium contaminated aquifer in batch experiments;(2) quantify rates of U(VI) desorption in column experiments with variable chemical conditions, and(3) quantify nonreactive tracer and U(VI) transport in field tests.</span></p>","language":"English","publisher":"U.S. Department of Energy","usgsCitation":"Curtis, G.P., Kohler, M., Kannappan, R., Briggs, M.A., and Day-Lewis, F.D., 2015, Upscaling of U (VI) desorption and transport from decimeter‐scale heterogeneity to plume‐scale modeling: Technical Report DOE-USGS--SC0003681, 18 p.","productDescription":"18 p.","ipdsId":"IP-063776","costCenters":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"links":[{"id":340477,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":311452,"type":{"id":15,"text":"Index Page"},"url":"https://www.osti.gov/scitech/servlets/purl/1170615"}],"country":"United States","state":"Colorado","city":"Naturita","otherGeospatial":"San Miguel River","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -108.85185241699219,\n              37.98858671553364\n            ],\n            [\n              -108.27919006347655,\n              37.98858671553364\n            ],\n            [\n              -108.27919006347655,\n              38.43799313099272\n            ],\n            [\n              -108.85185241699219,\n              38.43799313099272\n            ],\n            [\n              -108.85185241699219,\n              37.98858671553364\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5901b1bde4b0c2e071a99ba8","contributors":{"authors":[{"text":"Curtis, Gary P. 0000-0003-3975-8882 gpcurtis@usgs.gov","orcid":"https://orcid.org/0000-0003-3975-8882","contributorId":2346,"corporation":false,"usgs":true,"family":"Curtis","given":"Gary","email":"gpcurtis@usgs.gov","middleInitial":"P.","affiliations":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"preferred":true,"id":580081,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kohler, Matthias mkohler@usgs.gov","contributorId":2624,"corporation":false,"usgs":true,"family":"Kohler","given":"Matthias","email":"mkohler@usgs.gov","affiliations":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"preferred":true,"id":580082,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kannappan, Ramakrishnan rkannappan@usgs.gov","contributorId":5352,"corporation":false,"usgs":true,"family":"Kannappan","given":"Ramakrishnan","email":"rkannappan@usgs.gov","affiliations":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"preferred":true,"id":580083,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Briggs, Martin A. 0000-0003-3206-4132 mbriggs@usgs.gov","orcid":"https://orcid.org/0000-0003-3206-4132","contributorId":4114,"corporation":false,"usgs":true,"family":"Briggs","given":"Martin","email":"mbriggs@usgs.gov","middleInitial":"A.","affiliations":[{"id":610,"text":"Utah Water Science Center","active":true,"usgs":true},{"id":486,"text":"OGW Branch of Geophysics","active":true,"usgs":true},{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true},{"id":493,"text":"Office of Ground Water","active":true,"usgs":true}],"preferred":true,"id":580084,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Day-Lewis, Frederick D. 0000-0003-3526-886X daylewis@usgs.gov","orcid":"https://orcid.org/0000-0003-3526-886X","contributorId":1672,"corporation":false,"usgs":true,"family":"Day-Lewis","given":"Frederick","email":"daylewis@usgs.gov","middleInitial":"D.","affiliations":[{"id":486,"text":"OGW Branch of Geophysics","active":true,"usgs":true},{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true},{"id":493,"text":"Office of Ground Water","active":true,"usgs":true}],"preferred":true,"id":580085,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

In 1999, the Ministry of Petroleum, Energy, and Mines of the Islamic Republic of Mauritania implemented a program for the acquisition of the recommended basic geoscientific information, termed the first Projet de Renforcement Institutionnel du Secteur Minier (Project for Institutional Capacity Building in the Mining Sector, PRISM-I). As a result of the PRISM-I efforts, a great deal of new geological, geophysical, geochemical, remote sensing, and hydrological data became available for evaluation and synthesis. However, the Ministry of Petroleum, Energy, and Mines recognized that additional work was required to extract the full benefit of the data before it could be of greatest use to the international community and of benefit to the Mauritanian minerals and development sector.</p>\n<p>To achieve this benefit, the Ministry of Petroleum, Energy, and Mines implemented a second Projet de Renforcement Institutionnel du Secteur Minier (PRISM-II) in 2006 to consolidate, synthesize, and interpret all of the existing data, create a new 1:1,000,000 scale geologic map, and define the mineral resource potential of the country. A consortium in which the USGS was the lead scientific agency carried out the majority of the PRISM-II work. In 2008, the USGS Mauritania Minerals Project was interrupted due to political changes in Mauritania. PRISM-II work resumed in 2011, and was completed in 2013 with the delivery of over 40 separate written reports and plates, an access file containing the Mauritanian National Mineral Deposits Database, and an interactive GIS containing all of the multi-disciplinary data and interpretive areas of mineral resource potential in Mauritania.</p>\n<p>This report contains the USGS results of the PRISM-II Mauritania Minerals Project and is presented in cooperation with the Ministry of Petroleum, Energy, and Mines of the Islamic Republic of Mauritania. The Report is composed of separate chapters consisting of multidisciplinary interpretive reports with accompanying plates on the geology, structure, geochronology, geophysics, hydrogeology, geochemistry, remote sensing (Landsat TM and ASTER), and SRTM and ASTER digital elevation models of Mauritania. The syntheses of these multidisciplinary data formed the basis for additional chapters containing interpretive reports on 12 different commodities and deposit types known to occur in Mauritania, accompanied by countrywide mineral resource potential maps of each commodity/deposit type. The commodities and deposit types represented include: (1) Ni, Cu, PGE, and Cr deposits hosted in ultramafic rocks; (2) orogenic, Carlin-like, and epithermal gold deposits; (3) polymetallic Pb-Zn-Cu vein deposits; (4) sediment-hosted Pb-Zn-Ag deposits of the SEDEX and Mississippi Valley-type; (5) sediment-hosted copper deposits; ( 6) volcanogenic massive sulfide deposits; (7) iron oxide copper-gold deposits; (8) uranium deposits; (9) Algoma-, Superior-, and oolitic-type iron deposits; (10) shoreline Ti-Zr placer deposits; (11) incompatible element deposits hosted in pegmatites, alkaline rocks, and carbonatites, and; (12) industrial mineral deposits. Additional chapters include the Mauritanian National Mineral Deposits Database are accompanied by an explanatory text and the Mauritania Minerals Project GIS that contains all of the interpretive layers created by USGS scientists. Raw data not in the public domain may be obtained from the Ministry of Petroleum, Energy, and Mines in Nouakchott, Mauritania.</p>","language":"English, French","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr20131280","collaboration":"Prepared in cooperation with the Ministry of Petroleum, Energy, and Mines of the Islamic Republic of Mauritania","usgsCitation":"Taylor, C.D., ed., 2015, Second projet de renforcement institutionnel du secteur minier de la République  Islamique de Mauritanie (PRISM-II) phase V: U.S. Geological Survey Open-File Report 2013‒1280, 20 chaps., pages variable, pls. variable, https://dx.doi.org/10.3133/ofr20131280.

The regression equations that are the basis of the current application were developed in previous investigations by the U.S. Geological Survey (USGS) and are described at the USGS StreamStats Web sites for New York (<a href=\"http://water.usgs.gov/osw/streamstats/new_york.html\">http://water.usgs.gov/osw/streamstats/new_york.html</a>) and Vermont (<a href=\"http://water.usgs.gov/osw/streamstats/Vermont.html\">http://water.usgs.gov/osw/streamstats/Vermont.html</a>). These regression equations include several fixed landscape metrics that quantify aspects of watershed geomorphology, basin size, and land cover as well as a climate variable&mdash;either annual precipitation or annual runoff.</p>\n<p>The application uses predictions of future annual precipitation from five climate models and two future greenhouse gas emissions scenarios and provides results that are averaged over three future periods&mdash;2025 to 2049, 2050 to 2074, and 2075 to 2099. Results are presented in ensemble form as the mean, median, maximum, and minimum values among the five climate models for each greenhouse gas emissions scenario and period. These predictions of future annual precipitation are substituted into either the precipitation variable or a water balance equation for runoff to calculate potential future peak flows. This application is intended to be used only as an exploratory tool because (1) the regression equations on which the application is based have not been adequately tested outside the range of the current climate and (2) forecasting future precipitation with climate models and downscaling these results to a fine spatial resolution have a high degree of uncertainty. This report includes a discussion of the assumptions, uncertainties, and appropriate use of this exploratory application.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr20151235","collaboration":"Prepared in cooperation with the New York State Department of Transportation","usgsCitation":"Burns, D.A., Smith, M.J., and Freehafer, D.A., 2015, Development of flood regressions and climate change scenarios to explore estimates of future peak flows: U.S. Geological Survey Open-File Report 2015–1235, 11 p., https://dx.doi.org/10.3133/ofr20151235.","productDescription":"iii, 11 p.","numberOfPages":"16","onlineOnly":"Y","additionalOnlineFiles":"Y","ipdsId":"IP-063239","costCenters":[{"id":474,"text":"New York Water Science Center","active":true,"usgs":true}],"links":[{"id":313159,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2015/1235/ofr20151235.pdf","text":"Report","size":"643 kB","linkFileType":{"id":1,"text":"pdf"},"description":"OFR 2015-1235"},{"id":313160,"rank":3,"type":{"id":4,"text":"Application Site"},"url":"https://dx.doi.org/10.5066/F7WS8R9S","text":"Application of Flood Regressions and Climate Change Scenarios to Explore Estimates of Future Peak Flows"},{"id":313161,"rank":4,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2015/1235/index.html"},{"id":313157,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/2015/1235/coverthb.jpg"}],"contact":"<p>Director, New York Water Science Center<br>U.S. Geological Survey<br> 425 Jordan Road<br> Troy, NY 12180-8349<br> Email: <a href=\"mailto:dc_ny@usgs.gov\" data-mce-href=\"mailto:dc_ny@usgs.gov\">dc_ny@usgs.gov</a></p><p>Information requests:<br>(518) 285-5602 or visit our Web site at:<br><a href=\"http://ny.water.usgs.gov\" data-mce-href=\"http://ny.water.usgs.gov\">http://ny.water.usgs.gov</a><br></p>","tableOfContents":"<ul><li>Abstract</li><li>Introduction</li><li>StreamStats Program</li><li>Climate Change Application</li><li>Assumptions</li><li>Limitations and Uncertainty</li><li>Check Basin in Current StreamStats Before Using Climate Change Application</li><li>Sources of Uncertainty</li><li>References Cited</li></ul>","publishingServiceCenter":{"id":11,"text":"Pembroke PSC"},"publishedDate":"2015-12-31","noUsgsAuthors":false,"publicationDate":"2015-12-31","publicationStatus":"PW","scienceBaseUri":"56865fbfe4b0e7594ee74cbb","contributors":{"authors":[{"text":"Burns, Douglas A. 0000-0001-6516-2869 daburns@usgs.gov","orcid":"https://orcid.org/0000-0001-6516-2869","contributorId":1237,"corporation":false,"usgs":true,"family":"Burns","given":"Douglas","email":"daburns@usgs.gov","middleInitial":"A.","affiliations":[{"id":474,"text":"New York Water Science Center","active":true,"usgs":true}],"preferred":true,"id":584061,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Smith, Martyn J. 0000-0002-1107-9653 marsmith@usgs.gov","orcid":"https://orcid.org/0000-0002-1107-9653","contributorId":4474,"corporation":false,"usgs":true,"family":"Smith","given":"Martyn","email":"marsmith@usgs.gov","middleInitial":"J.","affiliations":[{"id":474,"text":"New York Water Science Center","active":true,"usgs":true}],"preferred":true,"id":584062,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Freehafer, Douglas A. dfreehaf@usgs.gov","contributorId":5181,"corporation":false,"usgs":true,"family":"Freehafer","given":"Douglas","email":"dfreehaf@usgs.gov","middleInitial":"A.","affiliations":[{"id":474,"text":"New York Water Science Center","active":true,"usgs":true}],"preferred":false,"id":584063,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Previous studies have successfully applied the U.S. Geological Survey&rsquo;s Transient Rainfall Infiltration and Grid-Based Regional Slope-Stability (TRIGRS) model (Baum et al.&nbsp;</span><span class=\"CitationRef\"><a href=\"http://link.springer.com/article/10.1007%2Fs10346-015-0670-6#CR2\">2002</a></span><span>) to compute infiltration-driven changes in the hillslopes&rsquo; factor of safety on small scales (i.e., tens of square kilometers). Soil data input for such models are difficult to obtain across larger regions. This work describes a novel methodology for the application of TRIGRS over broad areas with relatively uniform hydrogeological properties. The study area is a 550-km</span><sup><span>2</span></sup><span>&nbsp;region in Central Italy covered by post-orogenic Quaternary sediments. Due to the lack of field data, we assigned mechanical and hydrological property values through a statistical analysis based on literature review of soils matching the local lithologies. We calibrated the model using rainfall data from 25 historical rainfall events that triggered landslides. We compared the variation of pressure head and factor of safety with the landslide occurrence to identify the best fitting input conditions. Using calibrated inputs and a soil depth model, we ran TRIGRS for the study area. Receiver operating characteristic (ROC) analysis, comparing the model&rsquo;s output with a shallow landslide inventory, shows that TRIGRS effectively simulated the instability conditions in the post-orogenic complex during historical rainfall scenarios. The implication of this work is that rainfall-induced landslides over large regions may be predicted by a deterministic model, even where data on geotechnical and hydraulic properties as well as temporal changes in topography or subsurface conditions are not available.</span></p>","language":"English","publisher":"Springer-Verlag","publisherLocation":"Berlin,

Analysis of the transport and dispersal patterns of Asian carp eggs will facilitate the development and implementation of control strategies to target the early life stages. Experimenting with Asian carp eggs is complicated due to practical issues of obtaining eggs in close proximity to experimental facilities and extensive handling of eggs tends to damage them. Herein, we describe laboratory experiments using styrene beads (4.85 mm diameter) as synthetic surrogate eggs to mimic the physical properties of water-hardened silver carp eggs. The first set of experiments was completed in a rectangular vertical column filled with salt water. The salinity of the water was adjusted in an iterative fashion to obtain a close approximation of the fall velocity of the styrene beads to the mean fall velocity of silver carp water-hardened eggs. The terminal fall velocity of synthetic eggs was measured using an image processing method. The second set of experiments was performed in a temperature-controlled recirculatory flume with a sediment bed. The flume was filled with salt water, and synthetic eggs were allowed to drift under different flow conditions. Drifting behavior, suspension conditions, and settling characteristics of synthetic eggs were observed. At high velocities, eggs were suspended and distributed through the water column. Eggs that touched the sediment bed were re-entrained by the flow. Eggs saltated when they touched the bed, especially at moderate velocities and with a relatively flat bed. At lower velocities, some settling of the eggs was observed. With lower velocities and a flat bed, eggs were trapped near the walls of the flume. When bedforms were present, eggs were trapped in the lee of the bedforms in addition to being trapped near the flume walls. Results of this research study provide insights about transport, suspension, and dispersion of silver carp eggs. The knowledge gained from this study is useful to characterize the critical hydrodynamic conditions of the flow at which surrogates for silver carp water-hardened eggs settle out of suspension, and provides insight into how eggs may interact with riverbed sediments and morphology.</p>","language":"English","publisher":"Public Library of Science","publisherLocation":"San Francisco","doi":"10.1371/journal.pone.0145775","collaboration":"Great Lakes Restoration Initiative \nUniversity of Illinois","usgsCitation":"Garcia, T., Zuniga Zamalloa, C., Jackson, P., Murphy, E., and Garcia, M., 2015, A laboratory investigation of the suspension, transport, and settling of silver carp eggs using synthetic surrogates: PLoS ONE, p. 1-19, https://doi.org/10.1371/journal.pone.0145775.","productDescription":"19 p.","startPage":"1","endPage":"19","numberOfPages":"19","onlineOnly":"Y","additionalOnlineFiles":"N","ipdsId":"IP-064982","costCenters":[{"id":344,"text":"Illinois Water Science Center","active":true,"usgs":true}],"links":[{"id":471554,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1371/journal.pone.0145775","text":"Publisher Index Page"},{"id":313936,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"publishingServiceCenter":{"id":6,"text":"Columbus PSC"},"noUsgsAuthors":false,"publicationDate":"2015-12-29","publicationStatus":"PW","scienceBaseUri":"568e48cee4b0e7a44bc41839","contributors":{"authors":[{"text":"Garcia, Tatiana 0000-0002-1979-7246 tgarcia@usgs.gov","orcid":"https://orcid.org/0000-0002-1979-7246","contributorId":140327,"corporation":false,"usgs":true,"family":"Garcia","given":"Tatiana","email":"tgarcia@usgs.gov","affiliations":[{"id":344,"text":"Illinois Water Science Center","active":true,"usgs":true}],"preferred":true,"id":573635,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Zuniga Zamalloa, Carlo","contributorId":148037,"corporation":false,"usgs":false,"family":"Zuniga Zamalloa","given":"Carlo","email":"","affiliations":[{"id":16984,"text":"University of Illinois at Urbana-Champaign","active":true,"usgs":false}],"preferred":false,"id":573636,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Jackson, P.

The landslide killed 43 people. After overtopping and establishing a new channel through the landslide, the river incised into the landslide deposit over the course of 10 weeks draining the impoundment lake and mobilizing an estimated 280,000&plusmn;56,000 m<sup>3</sup> of predominantly sand-sized and finer sediment. During the first 4 weeks after the landslide, this eroded sediment caused downstream riverbed aggradation of 1&ndash;2 m within 1 km of the landslide and 0.4 m aggradation at Whitman Road Bridge, 3.5 km downstream. Winter high flows in 2014&ndash;15 were anticipated to mobilize an additional 220,000&plusmn;44,000 m<sup>3</sup> of sediment, potentially causing additional aggradation and exacerbating flood risk downstream of the landslide. Analysis of unit stream power and bed-material transport capacity along 35 km of the river corridor indicated that most fine-grained sediment will transport out of the North Fork Stillaguamish River, although some localized additional aggradation was possible. This new aggradation was not likely to exceed 0.1 m except in reaches within a few kilometers downstream of the landslide, where additional aggradation of up to 0.5 m is possible. Alternative river response scenarios, including continued mass wasting from the landslide scarp, major channel migration or avulsion, or the formation of large downstream wood jams, although unlikely, could result in reaches of significant local aggradation or channel change.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston,

In this first presentation of the dataset we (1) describe the basic features of the isotope values in relation to the Global Meteoric Water Line (GMWL), (2) evaluate space for time substitutions traditionally used to establish &delta;</span><span class=\"s2\"><sup>18</sup></span><span class=\"s1\">O-temperature relations, (3) evaluate site-to-site similarities across the network and identify those that are the most regionally representative, (4) examine atmospheric circulation patterns for several years with spatially coherent isotope patterns, and (5) provide examples of the implications this new dataset has for interpreting paleoclimate records (Bison Lake, Colorado and Minnetonka Cave, Idaho). Results indicate that snowpack &delta;</span><span class=\"s2\"><sup>18</sup></span><span class=\"s1\">O is rarely a simple proxy of temperature. Instead, it exhibits a high degree of spatial heterogeneity and temporal variance that reflect additional processes such as vapor transport and post-depositional modification. Despite these complexities we identify consistent climate-isotope patterns and regionally representative locations that serve to better define Holocene hydroclimate estimates and their uncertainty. Climate change has and will affect western U.S. snowpack and we suggest these changes can be better understood and anticipated by oxygen and hydrogen isotope-based reconstructions of Holocene hydroclimate using a process-based understanding of the controls on snowpack isotope ratios.</span></p>","language":"English","publisher":"Elseiver Ltd.","doi":"10.1016/j.quascirev.2015.03.023","usgsCitation":"Anderson, L., Berkelhammer, M., and Mast, M.A., 2015, Isotopes in North American Rocky Mountain snowpack 1993–2014: Quaternary Science Reviews, v. 131, p. 262-273, https://doi.org/10.1016/j.quascirev.2015.03.023.","productDescription":"12 p.","startPage":"262","endPage":"273","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-061199","costCenters":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"links":[{"id":312939,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Colorado, Idaho, Montana, New Mexico, Wyoming","otherGeospatial":"Bison Lake, Minnetonka Cave, Rocky Mountains","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -112.8515625,\n              49.03786794532644\n            ],\n            [\n              -111.796875,\n              47.96050238891509\n            ],\n            [\n              -110.830078125,\n              46.86019101567027\n            ],\n            [\n              -109.51171875,\n              46.437856895024204\n            ],\n            [\n              -108.5009765625,\n              45.583289756006316\n            ],\n            [\n              -108.06152343749999,\n              43.83452678223682\n            ],\n            [\n              -107.0068359375,\n              42.293564192170095\n            ],\n            [\n              -104.9853515625,\n              41.07935114946899\n            ],\n            [\n              -103.88671875,\n              38.06539235133249\n            ],\n            [\n              -104.32617187499999,\n              35.88905007936091\n            ],\n            [\n              -105.29296874999999,\n              34.161818161230386\n            ],\n            [\n              -107.70996093749999,\n              34.161818161230386\n            ],\n            [\n              -110.302734375,\n              35.53222622770337\n            ],\n            [\n              -112.8955078125,\n              41.27780646738183\n            ],\n            [\n              -116.806640625,\n              43.51668853502909\n            ],\n            [\n              -117.90527343750001,\n              46.49839225859763\n            ],\n            [\n              -118.125,\n              48.922499263758255\n            ],\n            [\n              -117.90527343750001,\n              49.095452162534826\n            ],\n            [\n              -112.8515625,\n              49.03786794532644\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"131","publishingServiceCenter":{"id":2,"text":"Denver PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"56825d29e4b0a04ef4925af5","contributors":{"authors":[{"text":"Anderson, Lesleigh 0000-0002-5264-089X land@usgs.gov","orcid":"https://orcid.org/0000-0002-5264-089X","contributorId":436,"corporation":false,"usgs":true,"family":"Anderson","given":"Lesleigh","email":"land@usgs.gov","affiliations":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"preferred":true,"id":583487,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Berkelhammer, Max ","contributorId":150891,"corporation":false,"usgs":false,"family":"Berkelhammer","given":"Max ","affiliations":[{"id":18133,"text":"University of Illinois Chicago","active":true,"usgs":false}],"preferred":false,"id":583488,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Mast, M.

The change in bioavailability of pesticide residues to <i>Lumbricus terrestris</i> L. relative to the unamended control soil was assessed using 4-L soil microcosms with and without plant cover in a 48-day experiment. The use of aged dairy manure compost and biosolids compost was found to be effective, especially in the planted treatments, at lowering the bioavailability factor (BAF) by 18&ndash;39%; however, BAF results for DDT in the unplanted soil treatments were unaffected or increased. The pine chip biochar utilized in this experiment was ineffective at lower the BAF of pesticides in the soil. The US EPA Soil Screening Level approach was used with our measured values. Addition of 10% of the aged dairy manure compost reduced the average hazard quotient values to below 1.0 for DDT&nbsp;+&nbsp;DDE and dieldrin. Results indicate this sustainable approach is appropriate to minimize risks to wildlife in areas of marginal organochlorine pesticide contamination. Application of this remediation approach has potential for use internationally in areas where historical pesticide contamination of soils remains a threat to wildlife populations.</span></p>","language":"English","publisher":"Applied Science Publishers","publisherLocation":"Barking, Essex, England","doi":"10.1016/j.envpol.2015.11.039","usgsCitation":"Centofantia, T., McConnell, L.L., Chaney, R.L., Beyer, W.N., Andradea, N.A., Hapeman, C.J., Torrents, A., Nguyen, A., Anderson, M.O., Novak, J.M., and Jackson, D., 2015, Organic amendments for risk mitigation of organochlorine pesticide residues in old orchard soils: Environmental Pollution, v. 210, p. 182-191, https://doi.org/10.1016/j.envpol.2015.11.039.","productDescription":"10 p.","startPage":"182","endPage":"191","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-066873","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true},{"id":34983,"text":"Contaminant Biology Program","active":true,"usgs":true}],"links":[{"id":312927,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Maryland","city":"Beltsville","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -76.88215255737305,\n              39.058516824330056\n            ],\n            [\n              -76.86447143554688,\n              39.05505105513096\n            ],\n            [\n              -76.84593200683594,\n              39.05238496307099\n            ],\n            [\n              -76.8464469909668,\n              39.04638588792801\n            ],\n            [\n              -76.83992385864258,\n              39.04198624231977\n            ],\n            [\n              -76.82653427124023,\n              39.03611962194588\n            ],\n            [\n              -76.81983947753906,\n              39.02451827974919\n            ],\n            [\n              -76.81692123413085,\n              39.01478235097201\n            ],\n            [\n              -76.81949615478516,\n              39.00651242716627\n            ],\n            [\n              -76.83116912841797,\n              39.00077626698007\n            ],\n            [\n              -76.8464469909668,\n              39.00077626698007\n            ],\n            [\n              -76.8819808959961,\n              39.00344430631642\n            ],\n            [\n              -76.89004898071289,\n              39.00584545569232\n            ],\n            [\n              -76.90206527709961,\n              39.00797974227288\n            ],\n            [\n              -76.92163467407227,\n              39.01651624461952\n            ],\n            [\n              -76.92249298095702,\n              39.022517855872856\n            ],\n            [\n              -76.92352294921875,\n              39.03931965708094\n            ],\n            [\n              -76.92094802856445,\n              39.05171842432893\n            ],\n            [\n              -76.90412521362305,\n              39.05638406341559\n            ],\n            [\n              -76.89176559448242,\n              39.0583835286602\n            ],\n            [\n              -76.88146591186523,\n              39.05865011974826\n            ],\n            [\n              -76.88215255737305,\n              39.058516824330056\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"210","publishingServiceCenter":{"id":10,"text":"Baltimore PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"56825d29e4b0a04ef4925af9","contributors":{"authors":[{"text":"Centofantia, Tiziana","contributorId":150859,"corporation":false,"usgs":false,"family":"Centofantia","given":"Tiziana","email":"","affiliations":[{"id":18121,"text":"Department of Civil and Environmental Engineering, University of Maryland College","active":true,"usgs":false}],"preferred":false,"id":583445,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"McConnell, Laura L.","contributorId":106437,"corporation":false,"usgs":true,"family":"McConnell","given":"Laura","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":583447,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Chaney, Rufus L.","contributorId":35455,"corporation":false,"usgs":true,"family":"Chaney","given":"Rufus","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":583449,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Beyer, W.

Our analyses show that surface water warming rates are dependent on combinations of climate and local characteristics, rather than just lake location, leading to the counterintuitive result that regional consistency in lake warming is the exception, rather than the rule. The most rapidly warming lakes are widely geographically distributed, and their warming is associated with interactions among different climatic factors&mdash;from seasonally ice-covered lakes in areas where temperature and solar radiation are increasing while cloud cover is diminishing (0.72&deg;C decade<sup>&minus;1</sup>) to ice-free lakes experiencing increases in air temperature and solar radiation (0.53&deg;C decade<sup>&minus;1</sup>).

GIWs constitute most of the wetlands in many North American landscapes, provide a disproportionately large fraction of wetland edges where many functions are enhanced, and form complexes with other water bodies to create spatial and temporal heterogeneity in the timing, flow paths, and magnitude of network connectivity. These attributes signal a critical role for GIWs in sustaining a portfolio of landscape functions, but legal protections remain weak despite preferential loss from many landscapes. GIWs lack persistent surface water connections, but this condition does not imply the absence of hydrological, biogeochemical, and biological exchanges with nearby and downstream waters. Although hydrological and biogeochemical connectivity is often episodic or slow (e.g., via groundwater), hydrologic continuity and limited evaporative solute enrichment suggest both flow generation and solute and sediment retention. Similarly, whereas biological connectivity usually requires overland dispersal, numerous organisms, including many rare or threatened species, use both GIWs and downstream waters at different times or life stages, suggesting that GIWs are critical elements of landscape habitat mosaics. Indeed, weaker hydrologic connectivity with downstream waters and constrained biological connectivity with other landscape elements are precisely what enhances some GIW functions and enables others. Based on analysis of wetland geography and synthesis of wetland functions, we argue that sustaining landscape functions requires conserving the entire continuum of wetland connectivity, including GIWs.</span></p>","language":"English","publisher":"Proceedings of the National Academy of Sciences","doi":"10.1073/pnas.1512650113","usgsCitation":"Cohen, M.J., Creed, I., Alexander, L., Basu, N., Calhoun, A.J., Craft, C., D’Amico, E., DeKeyser, E., Fowler, L., Golden, H., Jawitz, J.W., Kalla, P., Kirkman, L.K., Lane, C., Lang, M., Leibowitz, S.G., Lewis, D., Marton, J., McLaughlin, D.L., Mushet, D.M., Raanan-Kiperwas, H., Rains, M.C., Smith, L., and Walls, S.C., 2015, Do geographically isolated wetlands influence landscape functions?: Proceedings of the National Academy of Sciences of the United States of America, no.

We surveyed four altitudinal sites ranging from 1,200 to 2,200 m asl in the Kahuku Unit of Hawai&lsquo;i Volcanoes National Park (Kahuku) and three altitudinal sites ranging from 1,200 to 1,500 m asl in the Ka&lsquo;u Forest Reserve (Ka&lsquo;u) for the prevalence of avian disease and presence of mosquitoes. We collected blood samples from native and non-native forest birds and screened for avian malaria (Plasmodium relictum) using PCR diagnostics. We examined birds for signs of avian pox (Avipoxvirus sp.), knemidokoptic mange (Knemidokoptes jamaicensis) and feather ectoparasites. We also trapped adult mosquitoes (Culex quinquefasciatus and Aedes japonicus japonicus) and surveyed for available larval habitat. Between September, 2012 and October, 2014, we completed 3,219 hours of mist-netting in Kahuku capturing 515 forest birds and 3,103 hours of mist-netting in Ka&lsquo;u capturing 270 forest birds. We screened 750 blood samples for avian malaria. Prevalence of avian malaria in all species was higher in Ka&lsquo;u than Kahuku when all sites were combined for each tract. Prevalence of avian malaria in resident Hawai&lsquo;i &lsquo;amakihi (Chlorodrepanis virens) was greatest at the lowest elevation sites in Kahuku (26%; 1,201 m asl) and Ka&lsquo;u (42%; 1,178 m asl) and in general, prevalence decreased with increasing elevation and geographically from east to west. Significantly higher prevalence was seen in Ka&lsquo;u at comparable low and mid elevation sites but not at comparable high elevation sites. The overall presumptive pox prevalence was 1.7% (13/785) for both tracts, and it was higher in native birds than non-native birds, but it was not significant. Presumptive knemidokoptic mange was detected at two sites in lower elevation Kahuku, with prevalence ranging from 2‒4%. The overall prevalence of ectoparasites (Analges and Proctophyllodes spp.) was 6.7% (53/785). The site with the highest prevalence was Lower Glover in Kahuku (7.2%; 10/138) and Maka&lsquo;alia in Ka&lsquo;u. In general, mosquito larval habitat was more prevalent at lower elevation sites than higher elevation sites within the Kahuku&mdash;Ka&lsquo;u landscape, and more prevalent in Ka&lsquo;u than Kahuku. We observed significantly more available larval mosquito habitat in total belt transect plots in Ka&lsquo;u than Kahuku for both hapu&lsquo;u cavities (&Chi;2 = 47.06, df = 1, p &lt; 0.01) and other habitat types combined (i.e., ground pools, rock holes, tree holes) (&Chi;2 = 104.35, df = 1, p &lt; 0.01). Mosquitoes were most abundant at low elevation Kahuku, but were captured at all sites up to 1,532 m asl in Kahuku. The malarial infection rate of live mosquitoes was 21% (39/186) at Kahuku and 25% (2/8) at Ka&lsquo;u. There were 19 times more larval habitats available in Ka&lsquo;u than Kahuku on survey transects, yet we captured 53 times more C. quinquefasciatus mosquitoes in Kahuku. We captured very few adult A. j. japonicus across the landscape (Ntotal = 6) and no Aedes albopictus were detected in this study. Larval surveys along ranch roads and infrastructure revealed that ground pools along rutted, overgrown ranch roads were the likely source of Kahuku mosquitoes. We did not find mosquito larvae associated with ranching infrastructure. Unlike the low elevation forests on windward Hawai&lsquo;i Island, avian malaria prevalence, mosquito abundance, and the density of available larval habitat in Kahuku and Ka&lsquo;u were relatively low. Although altitudinal variations in climate appear to be the primary factors limiting the distribution of avian disease, habitat type, avian movements, human activity, and feral pig (Sus scrofa) management all may play important roles in determining the prevalence of avian malaria across the Kahuku&mdash;Ka&lsquo;u landscape.</p>","language":"English","publisher":"University of Hawaii at Hilo","publisherLocation":"Hilo, HI","usgsCitation":"Gaudioso, J., Lapointe, D., Atkinson, C.T., and Egan, A.N., 2015, Avian disease and mosquito vectors in the Kahuku unit of Hawai`i Volcanoes National Park and Ka`u Forest Reserve: Technical Report HCSU-070, Report: iv, 41 p.","productDescription":"Report: iv, 41 p.","startPage":"1","endPage":"41","numberOfPages":"45","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-071145","costCenters":[{"id":521,"text":"Pacific Island Ecosystems Research Center","active":false,"usgs":true}],"links":[{"id":326259,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Hawaii","publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"57a9ad38e4b05e859bdfb845","contributors":{"authors":[{"text":"Gaudioso, Jacqueline jgaudioso@usgs.gov","contributorId":5637,"corporation":false,"usgs":true,"family":"Gaudioso","given":"Jacqueline","email":"jgaudioso@usgs.gov","affiliations":[{"id":524,"text":"Pacific Islands Ecosystems Research Center","active":false,"usgs":true}],"preferred":true,"id":583758,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"LaPointe, Dennis A. 0000-0002-6323-263X dlapointe@usgs.gov","orcid":"https://orcid.org/0000-0002-6323-263X","contributorId":150365,"corporation":false,"usgs":true,"family":"LaPointe","given":"Dennis","email":"dlapointe@usgs.gov","middleInitial":"A.","affiliations":[{"id":521,"text":"Pacific Island Ecosystems Research Center","active":false,"usgs":true}],"preferred":true,"id":583759,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Atkinson, Carter T. 0000-0002-4232-5335 catkinson@usgs.gov","orcid":"https://orcid.org/0000-0002-4232-5335","contributorId":1124,"corporation":false,"usgs":true,"family":"Atkinson","given":"Carter","email":"catkinson@usgs.gov","middleInitial":"T.","affiliations":[{"id":521,"text":"Pacific Island Ecosystems Research Center","active":false,"usgs":true},{"id":154,"text":"California Water Science Center","active":true,"usgs":true},{"id":5049,"text":"Pacific Islands Ecosys Research Center","active":true,"usgs":true}],"preferred":true,"id":583760,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Egan, Ariel N.","contributorId":150954,"corporation":false,"usgs":false,"family":"Egan","given":"Ariel","email":"","middleInitial":"N.","affiliations":[{"id":13351,"text":"University of Hawaii Cooperative Studies Unit","active":true,"usgs":false}],"preferred":false,"id":583761,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

This report presents the results of a statewide study for which regional regression equations were developed for estimating 13 flow-duration curve statistics and 10 low-flow frequency statistics at ungaged stream locations in Minnesota. The 13 flow-duration curve statistics estimated by regression equations include the 0.0001, 0.001, 0.02, 0.05, 0.1, 0.25, 0.50, 0.75, 0.9, 0.95, 0.99, 0.999, and 0.9999 exceedance-probability quantiles. The low-flow frequency statistics include annual and seasonal (spring, summer, fall, winter) 7-day mean low flows, seasonal 30-day mean low flows, and summer 122-day mean low flows for a recurrence interval of 10 years. Estimates of the 13 flow-duration curve statistics and the 10 low-flow frequency statistics are provided for 196 U.S. Geological Survey continuous-record streamgages using streamflow data collected through September 30, 2012.</p>\n<p>The study area includes 196 streamgages located within Minnesota and 50 miles beyond the State&rsquo;s borders in North Dakota, South Dakota, Iowa, and Wisconsin. The study area was divided into five regions that were developed in a previous study using the concept of hydrologic landscape units. Geographic information system software was used to calculate 18 characteristics investigated as potential explanatory variables in regression analyses for each streamgage drainage basin. Trend analyses indicated statistically significant trends in summer 7-day low flows that were not related to precipitation patterns for 19 streamgages. For 16 of these streamgages, the streamflow record was subset using structural change analysis to identify the most recent period of record without a significant trend. The three remaining streamgages with significant trends were excluded from the final analysis because the effective period of record without a significant trend was less than 10 years.</p>\n<p>Because several streams in this study have zero flow as their minimum reported flow, weighted left-censored regression was used to analyze the flow data in an unbiased manner, with weights based on the number of years of record. A total of 115 regression equations were developed in this study to calculate flow-duration curve and low-flow frequency statistics for ungaged locations in the study area. In addition, data from 25 pairs of streamgages were used to develop drainage-area ratio equations that can be used to estimate streamflow statistics at ungaged locations on streams that have a streamgage in another location. Streamflow statistics estimated using regional regression and drainage-area ratio equations were compared among regions. For regions A, D, and E, drainagearea ratio equations were more accurate than regional regression equations for flows, but regional regression equations were more accurate for high flows. For region F, regional regression equations were consistently more accurate than drainage-area ratio equations. For region BC, the pattern in accuracies of regional regression and drainage-area ratio equations between low flows and high flows was not consistent.</p>\n<p>Equations developed in this study apply only to stream locations where flows are not substantially affected by regulation, diversion, or urbanization. All equations presented in this study will be incorporated into StreamStats, a web-based geographic information system tool developed by the U.S. Geological Survey. StreamStats allows users to obtain streamflow statistics, basin characteristics, and other information for user-selected locations on streams through an interactive map.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/sir20155170","collaboration":"Prepared in cooperation with the Minnesota Pollution

The wetland and back-barrier shorelines of the New Jersey barrier islands were changed by wave action and storm surge from Hurricane Sandy in 2012. The U.S. Geological Survey Coastal and Marine Geology Program is assessing the impact of Hurricane Sandy to understand its historical context and the vulnerability of wetland systems. These assessments require data that document physical changes over time, such as maps, aerial photographs, satellite imagery, and lidar elevation data.</p>\n<p>This Data Series Report includes open-ocean shorelines, back-island shorelines, back-island shoreline points, sand polygons, and sand lines for the undeveloped areas of New Jersey barrier islands. These data were extracted from orthoimagery (aerial photography) taken between March 9, 1991, and July 30, 2013. The images used were 0.3&ndash;1-meter (m)-resolution <a href=\"http://earthexplorer.usgs.gov/\" target=\"_blank\">U.S. Geological Survey Digital Orthophoto Quarter Quads</a> (DOQQ), <a href=\"http://datagateway.nrcs.usda.gov/GDGOrder.aspx\" target=\"_blank\">U.S. Department of Agriculture National Agriculture Imagery Program</a> (NAIP) images, <a href=\"http://storms.ngs.noaa.gov/storms/sandy/index.html\" target=\"_blank\">National Oceanic and Atmospheric Administration images</a>, and <a href=\"https://njgin.state.nj.us/NJ_NJGINExplorer/DataDownloads.jsp\" target=\"_blank\">New Jersey Geographic Information Network</a> images. The back-island shorelines were hand-digitized at the intersects of the apparent back-island shoreline and transects spaced at 20-m intervals. The open-ocean shorelines were hand-digitized at the approximate still-water level, such as tide level, which was fit through the average position of waves and swash apparent on the beach. Hand-digitizing was done at a scale of approximately 1:2,000. The sand polygons were derived by an image-processing unsupervised classification technique that separates images into classes. The classes were then visually categorized as either sand or not sand. Sand lines were taken from the sand polygons. Also included in this report are 20-m-spaced transect lines and the transect base lines.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ds960","usgsCitation":"Guy, K.K., 2015, Back-Island and Open-Ocean Shorelines, and Sand Areas of the Undeveloped Areas of New Jersey Barrier Islands, March 9, 1991, to July 30, 2013.

Here we evaluate a high-throughput genetic barcoding approach to characterize trap-collected pollen from multiple North Dakota apiaries across multiple years. We used the Illumina MiSeq platform to generate sequence scaffolds from non-overlapping 300-bp paired-end sequencing reads of the ribosomal internal transcribed spacers (ITS). Full-length sequence scaffolds represented ~530 bp of ITS sequence after adapter trimming, drawn from the 5&rsquo; of ITS1 and the 3&rsquo; of ITS2, while skipping the uninformative 5.8S region. Operational taxonomic units (OTUs) were picked from scaffolds clustered at 97% identity, searched by BLAST against the nt database, and given taxonomic assignments using the paired-read lowest common ancestor approach. Taxonomic assignments and quantitative patterns were consistent with known plant distributions, phenology, and observational reports of pollen foraging, but revealed an unexpected contribution from non-crop graminoids and wetland plants. The mean number of plant species assignments per sample was 23.0 (+/- 5.5) and the mean species diversity (effective number of equally abundant species) was 3.3 (+/- 1.2). Bray-Curtis similarities showed good agreement among samples from the same apiary and sampling date. Rarefaction plots indicated that fewer than 50,000 reads are typically needed to characterize pollen samples of this complexity. Our results show that a pre-compiled, curated reference database is not essential for genus-level assignments, but species-level assignments are hindered by database gaps, reference length variation, and probable errors in the taxonomic assignment, requiring post-hoc evaluation. Although the effective per-sample yield achieved using custom MiSeq amplicon primers was less than the machine maximum, primarily due to lower &ldquo;read2&rdquo; quality, further protocol optimization and/or a modest reduction in multiplex scale should offset this difficulty. As small quantities of pollen are sufficient for amplification, our approach might be extendable to other questions or species for which large pollen samples are not available.</p>","language":"English","publisher":"PLoS","publisherLocation":"San Francisco","doi":"10.1371/journal.pone.0145365","usgsCitation":"Cornman, R.S., Otto, C., Iwanowicz, D.D., and Pettis, J.S., 2015, Taxonomic characterization of honey bee (<i>Apis mellifera</i>) pollen foraging based on non-overlapping paired-end sequencing of nuclear ribosomal loci: PLoS ONE, v. 10, no. 12, p. 1-26, https://doi.org/10.1371/journal.pone.0145365.","productDescription":"26 p.","startPage":"1","endPage":"26","onlineOnly":"Y","additionalOnlineFiles":"N","ipdsId":"IP-067288","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true},{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":471557,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1371/journal.pone.0145365","text":"Publisher Index Page"},{"id":313041,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"North Dakota","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -98.96484375,\n              46.84704298339389\n            ],\n            [\n              -98.96484375,\n              47.44852243794931\n            ],\n            [\n              -97.83599853515625,\n              47.44852243794931\n            ],\n            [\n              -97.83599853515625,\n              46.84704298339389\n            ],\n            [\n              -98.96484375,\n              46.84704298339389\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"10","issue":"12","publishingServiceCenter":{"id":2,"text":"Denver PSC"},"noUsgsAuthors":false,"publicationDate":"2015-12-23","publicationStatus":"PW","scienceBaseUri":"56850061e4b0a04ef4933751","contributors":{"authors":[{"text":"Cornman, Robert S. 0000-0001-9511-2192 rcornman@usgs.gov","orcid":"https://orcid.org/0000-0001-9511-2192","contributorId":5356,"corporation":false,"usgs":true,"family":"Cornman","given":"Robert","email":"rcornman@usgs.gov","middleInitial":"S.","affiliations":[{"id":365,"text":"Leetown Science Center","active":true,"usgs":true},{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":true,"id":583636,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Otto, Clint 0000-0002-7582-3525 cotto@usgs.gov","orcid":"https://orcid.org/0000-0002-7582-3525","contributorId":5426,"corporation":false,"usgs":true,"family":"Otto","given":"Clint","email":"cotto@usgs.gov","affiliations":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"preferred":true,"id":583637,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Iwanowicz, Deborah D. 0000-0002-9613-8594 diwanowicz@usgs.gov","orcid":"https://orcid.org/0000-0002-9613-8594","contributorId":2253,"corporation":false,"usgs":true,"family":"Iwanowicz","given":"Deborah","email":"diwanowicz@usgs.gov","middleInitial":"D.","affiliations":[{"id":365,"text":"Leetown Science Center","active":true,"usgs":true}],"preferred":true,"id":583638,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Pettis, Jeffery S","contributorId":150913,"corporation":false,"usgs":false,"family":"Pettis","given":"Jeffery","email":"","middleInitial":"S","affiliations":[{"id":6758,"text":"USDA-ARS","active":true,"usgs":false}],"preferred":false,"id":583639,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}
