Finding ways to ameliorate human impacts on biodiversity and to sustain and restore the ecosystem services on which we depend is a grand scientific and societal challenge. Conservation paleobiology is an emerging discipline that uses geohistorical data to meet these challenges by developing and testing models of how biota respond to environmental stressors. Here we (</span><i>a</i><span>) describe how the discipline has already provided insights about biotic responses to key environmental stressors, (</span><i>b</i><span>) outline research aimed at disentangling the effects of multiple stressors, (</span><i>c</i><span>) provide examples of deliverables for managers and policy makers, and (</span><i>d</i><span>) identify methodological advances in geohistorical analysis that will foster the next major breakthroughs in conservation outcomes. We highlight cases for which exclusive reliance on observations of living biota may lead researchers to erroneous conclusions about the nature and magnitude of biotic change, vulnerability, and resilience.</span></p>","language":"English","publisher":"Annual Reviews Inc.","publisherLocation":"Palo Alto, CA","doi":"10.1146/annurev-earth-040610-133349","usgsCitation":"Dietl, G.P., Kidwell, S.M., Brenner, M., Burney, D.A., Flessa, K.W., Jackson, S.T., and Koch, P.L., 2015, Conservation paleobiology: Leveraging knowledge of the past to inform conservation and restoration: Annual Review of Earth and Planetary Sciences, v. 43, p. 79-103, https://doi.org/10.1146/annurev-earth-040610-133349.","startPage":"79","endPage":"103","numberOfPages":"25","ipdsId":"IP-056769","costCenters":[{"id":569,"text":"Southwest Climate Science Center","active":true,"usgs":true}],"links":[{"id":472098,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1146/annurev-earth-040610-133349","text":"Publisher Index Page"},{"id":329515,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"43","publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"57ffdeffe4b0824b2d179cf8","contributors":{"authors":[{"text":"Dietl, Gregory P.","contributorId":175306,"corporation":false,"usgs":false,"family":"Dietl","given":"Gregory","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":650746,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kidwell, Susan M.","contributorId":18003,"corporation":false,"usgs":false,"family":"Kidwell","given":"Susan","email":"","middleInitial":"M.","affiliations":[{"id":33013,"text":"Department of the Geophysical Sciences, University of Chicago","active":true,"usgs":false}],"preferred":false,"id":650747,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Brenner, Mark","contributorId":86380,"corporation":false,"usgs":true,"family":"Brenner","given":"Mark","email":"","affiliations":[],"preferred":false,"id":650748,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Burney, David A.","contributorId":175307,"corporation":false,"usgs":false,"family":"Burney","given":"David","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":650749,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Flessa, Karl W.","contributorId":175308,"corporation":false,"usgs":false,"family":"Flessa","given":"Karl","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":650750,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Jackson, Stephen T. 0000-0002-1487-4652 stjackson@usgs.gov","orcid":"https://orcid.org/0000-0002-1487-4652","contributorId":344,"corporation":false,"usgs":true,"family":"Jackson","given":"Stephen","email":"stjackson@usgs.gov","middleInitial":"T.","affiliations":[{"id":560,"text":"South Central Climate Science Center","active":true,"usgs":true},{"id":569,"text":"Southwest Climate Science Center","active":true,"usgs":true}],"preferred":true,"id":650674,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Koch, Paul L.","contributorId":6742,"corporation":false,"usgs":true,"family":"Koch","given":"Paul","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":650751,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

Wetlands are areas where the water table is at or near the land surface and standing shallow water is present for much or all of the growing season. We discuss how monitoring data can be used to document variation in annual flooding and drying patterns of wetlands monitored across Yellowstone and Grand Teton national parks, investigate how these patterns are related to a changing climate, and explore how drying of wetlands may impact amphibians. The documented declines of some amphibian species are of growing concern to scientists and land managers alike, in part because disappearances have occurred in some of the most protected places. These disappearances are a recognized component of what is being described as Earth’s sixth mass extinction.</p>","language":"English","publisher":"Yellowstone Association for Natural

Waveform comparison of the largest events of the 2008–2010 swarm with an M</span><sub>L</sub><span><span>&nbsp;</span>4.0 event that occurred during swarm activity between 1953 and 1957 in the same region shows similar P- and S-wave arrivals at the Belgian Uccle seismic station. The geometry depicted by the hypocentral distribution is consistent with a nearly vertical, left-lateral strike-slip fault taking place in a current local WNW–ESE oriented local maximum horizontal stress field. To determine a relevant tectonic structure, a systematic matched filtering approach of aeromagnetic data, which can approximately locate isolated anomalies associated with hypocentral depths, has been applied. Matched filtering shows that the 2008–2010 seismic swarm occurred along a limited-sized fault which is situated in slaty, low-magnetic rocks of the Mousty Formation. The fault is bordered at both ends with obliquely oriented magnetic gradients. Whereas the NW end of the fault is structurally controlled, its SE end is controlled by a magnetic gradient representing an early-orogenic detachment fault separating the low-magnetic slaty Mousty Formation from the high-magnetic Tubize Formation. The seismic swarm is therefore interpreted as a sinistral reactivation of an inherited NW–SE oriented isolated fault in a weakened crust within the Cambrian core of the Brabant Massif.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.tecto.2015.05.026","usgsCitation":"Van Noten, K., Lecocq, T., Shah, A.K., and Camelbeeck, T., 2015, Seismotectonic significance of the 2008–2010 Walloon Brabant seismic swarm in the Brabant Massif, Belgium: Tectonophysics, v. 656, p. 20-38, https://doi.org/10.1016/j.tecto.2015.05.026.","productDescription":"19 p.","startPage":"20","endPage":"38","ipdsId":"IP-063684","costCenters":[{"id":211,"text":"Crustal Geophysics and Geochemistry Science Center","active":true,"usgs":true}],"links":[{"id":344132,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Belgium","otherGeospatial":"Brabant Massif","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              2.3,\n              50.35\n            ],\n            [\n              5.9,\n              50.35\n            ],\n            [\n              5.9,\n              51.65\n            ],\n            [\n              2.3,\n              51.65\n            ],\n            [\n              2.3,\n              50.35\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"656","publishingServiceCenter":{"id":2,"text":"Denver PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5971c1c5e4b0ec1a4885dae4","contributors":{"authors":[{"text":"Van Noten, Koen","contributorId":141029,"corporation":false,"usgs":false,"family":"Van Noten","given":"Koen","email":"","affiliations":[{"id":13659,"text":"Royal Observatory of Belgium","active":true,"usgs":false}],"preferred":false,"id":548036,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"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":548037,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Shah, Anjana K. 0000-0002-3198-081X ashah@usgs.gov","orcid":"https://orcid.org/0000-0002-3198-081X","contributorId":2297,"corporation":false,"usgs":true,"family":"Shah","given":"Anjana","email":"ashah@usgs.gov","middleInitial":"K.","affiliations":[{"id":171,"text":"Central Mineral and Environmental Resources Science Center","active":true,"usgs":true},{"id":211,"text":"Crustal Geophysics and Geochemistry Science Center","active":true,"usgs":true}],"preferred":true,"id":548035,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"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":548038,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

The potential listing of the greater sage-grouse (<i class=\"EmphasisTypeItalic\">Centrocercus urophasianus</i>) under the U.S. Endangered Species Act has spurred a decade of juniper removal efforts, yet limited research has evaluated program effectiveness. We used a multi-objective spatially explicit model to identify optimal juniper removal sites in Northeastern California across weighted goals for ecological (sage-grouse habitat) and economic (cattle forage production) benefits. We also extended the analysis through alternative case scenarios that tested the effects of coordination among federal agencies, budgetary constraints, and the use of fire as a juniper treatment method. We found that sage-grouse conservation and forage production goals are somewhat complementary, but the extent of complementary benefits strongly depends on spatial factors and management approaches. Certain management actions substantially increase achievable benefits, including agency coordination and the use of prescribed burns to remove juniper. Critically, our results indicate that juniper management strategies designed to increase cattle forage do not necessarily achieve measurable sage-grouse benefits, underscoring the need for program evaluation and monitoring.</p>","language":"English","publisher":"Springer","doi":"10.1007/s00267-015-0521-1","usgsCitation":"Farzan, S., Young, D.J., Dedrick, A.G., Hamilton, M., Porse, E.C., Coates, P.S., and Sampson, G., 2015, Western juniper management: assessing strategies for improving greater sage-grouse habitat and rangeland productivity: Environmental Management, v. 56, no. 3, p. 675-683, https://doi.org/10.1007/s00267-015-0521-1.","productDescription":"9 p.","startPage":"675","endPage":"683","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-063191","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":472099,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1007/s00267-015-0521-1","text":"Publisher Index Page"},{"id":306677,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California, Oregon, Nevada","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -121.67358398437499,\n              39.07890809706475\n            ],\n            [\n              -121.67358398437499,\n              42.382894009614056\n            ],\n            [\n              -117.740478515625,\n              42.382894009614056\n            ],\n            [\n              -117.740478515625,\n              39.07890809706475\n            ],\n            [\n              -121.67358398437499,\n              39.07890809706475\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"56","issue":"3","publishingServiceCenter":{"id":1,"text":"Sacramento PSC"},"noUsgsAuthors":false,"publicationDate":"2015-05-10","publicationStatus":"PW","scienceBaseUri":"55cdbfc1e4b08400b1fe145b","contributors":{"authors":[{"text":"Farzan, Shahla","contributorId":146396,"corporation":false,"usgs":false,"family":"Farzan","given":"Shahla","email":"","affiliations":[{"id":7214,"text":"University of California, Davis","active":true,"usgs":false}],"preferred":false,"id":567725,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Young, Derek J.N.","contributorId":146397,"corporation":false,"usgs":false,"family":"Young","given":"Derek","email":"","middleInitial":"J.N.","affiliations":[{"id":7214,"text":"University of California, Davis","active":true,"usgs":false}],"preferred":false,"id":567726,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Dedrick, Allison G.","contributorId":146398,"corporation":false,"usgs":false,"family":"Dedrick","given":"Allison","email":"","middleInitial":"G.","affiliations":[{"id":7214,"text":"University of California, Davis","active":true,"usgs":false}],"preferred":false,"id":567727,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hamilton, Mattew","contributorId":146399,"corporation":false,"usgs":false,"family":"Hamilton","given":"Mattew","email":"","affiliations":[{"id":7214,"text":"University of California, Davis","active":true,"usgs":false}],"preferred":false,"id":567728,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Porse, Erik C.","contributorId":146400,"corporation":false,"usgs":false,"family":"Porse","given":"Erik","email":"","middleInitial":"C.","affiliations":[{"id":7214,"text":"University of California, Davis","active":true,"usgs":false}],"preferred":false,"id":567729,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Coates, Peter S. 0000-0003-2672-9994 pcoates@usgs.gov","orcid":"https://orcid.org/0000-0003-2672-9994","contributorId":3263,"corporation":false,"usgs":true,"family":"Coates","given":"Peter","email":"pcoates@usgs.gov","middleInitial":"S.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":567724,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Sampson, Gabriel","contributorId":146401,"corporation":false,"usgs":false,"family":"Sampson","given":"Gabriel","email":"","affiliations":[{"id":7214,"text":"University of California, Davis","active":true,"usgs":false}],"preferred":false,"id":567730,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

The model was calibrated by using the current stage-discharge relations at three USGS streamgages: the White River at Indianapolis (station number 03353000), the White River at Michigan Street at Indianapolis (station number 03352953), and the White River at Stout Generating Station at Indianapolis (station number 03353611).</p>\n<p>The hydraulic model was then used to compute 11 water-surface profiles for flood stages at 1-foot (ft) intervals referenced to the White River at Indianapolis streamgage datum and ranging from 10 ft, or the NWS &ldquo;action stage,&rdquo; to 20 ft, which is the highest stage in the stage-discharge relation for the streamgage and the NWS &ldquo;moderate flood stage.&rdquo;</p>\n<p>The simulated water-surface profiles were then combined with a geographic information system digital elevation model (derived from light detection and ranging [lidar] data having a vertical 0.183-ft root mean squared error and 5.0-ft horizontal resolution) to delineate the area flooded at each water level.</p>\n<p>The availability of these maps, along with Internet information regarding current stage from the USGS streamgage and forecasted high-flow stages from the NWS, will provide emergency management personnel and residents with information that is critical for flood response activities such as evacuations and road closures, as well as for postflood recovery efforts.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/sir20155051","collaboration":"Prepared in cooperation with the Indiana Office of Community and Rural Affairs","usgsCitation":"Nystrom, E.A., 2015, Flood-inundation maps for the White River at Indianapolis, Indiana, 2014: U.S. Geological Survey Scientific Investigations Report 2015-5051, Report: iv, 12 p.;

Although water is often assumed to be plentiful in Rhode Island because of abundant rainfall, an adequate supply of water is not always available everywhere in the state during dry periods. Concerns that water demand may exceed supply are greatest during the summer, when lower water levels and increased drought potential combine with seasonal increases in peak water demand (Rhode Island Water Resources Board, 2012). High summer water demands are due to increases in outdoor water use, such as lawn watering and agricultural irrigation, and to increased summer population in coastal areas. Water-supply concerns are particularly acute in central and southern Rhode Island, where groundwater is the primary source of drinking water.</p>\n<p>The Big River and Mishnock River Basins are subbasins of the South Branch of the Pawtuxet River Basin in central and southern Rhode Island. These basins&mdash;referred to together as &ldquo;the Big River area&rdquo; for the purposes of this report&mdash;are undeveloped relative to other nearby areas and provide a potential source of high-quality public drinking water for central and southern Rhode Island.</p>\n<p>After the severe drought of the 1960s, the State of Rhode Island acquired land in the Big River area with the intention of building a water-supply reservoir. The reservoir was not built because of concerns over potential environmental impacts and projected statewide water-supply needs (U.S. Environmental Protection Agency, 1989). The land acquired for the reservoir (13.4 mi<sup>2</sup>), called the Big River Management Area (BRMA), is currently managed by the RIWRB as a future source for public water supply and as open space. In the 1980s, the RIWRB began to consider whether the BRMA could supply water from its aquifers (groundwater). Groundwater withdrawals for public or other water-supply needs can alter the hydrologic conditions and ecologic communities of surrounding rivers, lakes, and wetlands by removing water from these systems. Consequently, the RIWRB was interested in determining optimal amounts of groundwater that could be withdrawn from the BRMA for public supply while minimizing the effects on rivers, lakes, streams, and wetlands that also rely on this water.</p>\n<p>For nearly two decades, the RIWRB has conducted a series of cooperative studies with the U.S. Geological Survey (USGS). The goals of these studies have been to (1) evaluate and characterize the water resources of the BRMA and the greater Big River area, and (2) identify sustainable levels of groundwater use that would minimize effects on water resources. This fact sheet describes the major findings of those studies.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston,

An existing network of gravity stations in the Sierra Vista Subwatershed was revised in 2014 to better understand the spatial distribution of changes in aquifer storage, especially with relation to ephemeral channel recharge and a groundwater cone of depression associated with pumping in the greater Sierra Vista area. In addition, the network was extended to provide baseline data for possible future enhanced-recharge projects.</p>\n<p>This report (1) summarizes changes to the Sierra Vista Subwatershed regional time-lapse gravity network with respect to station locations and (2) presents 2014 and 2015 gravity measurements and gravity values at each station. A prior gravity network, established between 2000 and 2005, was revised in 2014 to cover a larger number of stations over a smaller geographic area in order to decrease measurement and interpolation uncertainty. The network currently consists of 59 gravity stations, including 14 absolute-gravity stations. Following above-average rainfall during summer 2014, gravity increased at all but one of the absolute-gravity stations that were observed in both June 2014 and January 2015. This increase in gravity indicates increased groundwater storage in the aquifer and (or) unsaturated zone as a result of rainfall and infiltration.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr20151086","collaboration":"Prepared in cooperation with The Nature Conservancy","usgsCitation":"Kennedy, J.R., 2015, Gravity data from the Sierra Vista Subwatershed, Upper San Pedro Basin, Arizona: U.S. Geological Survey Open-File Report 2015-1086, iv, 26 p., https://doi.org/10.3133/ofr20151086.","productDescription":"iv, 26 p.","numberOfPages":"34","onlineOnly":"Y","additionalOnlineFiles":"N","ipdsId":"IP-063495","costCenters":[{"id":128,"text":"Arizona Water Science Center","active":true,"usgs":true}],"links":[{"id":300169,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr20151086.JPG"},{"id":337238,"rank":4,"type":{"id":30,"text":"Data Release"},"url":"https://dx.doi.org/10.5066/F7SQ8XHX","text":"Gravity change from 2014 to 2015, Sierra Vista Subwatershed, Upper San Pedro Basin, Arizona"},{"id":300166,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2015/1086/"},{"id":300168,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2015/1086/pdf/ofr2015-1086.pdf","size":"4 MB","linkFileType":{"id":1,"text":"pdf"}}],"scale":"100000","projection":"Universal Transverse Mercator projection","country":"United States","state":"Arizona","otherGeospatial":"Upper San Pedro Basin","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -110.37483215332031,\n              31.357741484720663\n            ],\n            [\n              -110.37483215332031,\n              31.65221239429719\n            ],\n            [\n              -110.0830078125,\n              31.65221239429719\n            ],\n            [\n              -110.0830078125,\n              31.357741484720663\n            ],\n            [\n              -110.37483215332031,\n              31.357741484720663\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"554dd01be4b082ec54129eeb","contributors":{"authors":[{"text":"Kennedy, Jeffrey R. 0000-0002-3365-6589 jkennedy@usgs.gov","orcid":"https://orcid.org/0000-0002-3365-6589","contributorId":2172,"corporation":false,"usgs":true,"family":"Kennedy","given":"Jeffrey","email":"jkennedy@usgs.gov","middleInitial":"R.","affiliations":[{"id":128,"text":"Arizona Water Science Center","active":true,"usgs":true}],"preferred":true,"id":546353,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The rapid invasion of this top predator has had a marked negative effect on fish populations in the Western Atlantic and the Caribbean. It is now well documented that lionfish are invading many tropical and sub-tropical habitats. However, there are fewer data available on the change in lionfish abundance over time and the variation of body size and diet across habitats. A recent study in San Salvador, Bahamas, found body size differences between individuals from mangrove and reef systems. That study further suggested that ontogenetic investigation of habitat use patterns could help clarify whether lionfish are using the mangrove areas of San Salvador as nurseries. The aim of the present study is to determine temporal trends in lionfish relative abundance in mangrove and reef systems in San Salvador, and to further assess whether there is evidence suggesting an ontogenetic shift from mangroves to reef areas. Accordingly, we collected lionfish from mangrove and reef habitats and calculated catch per unit effort (a proxy for relative abundance), compared body size distributions across these two systems, and employed a combination of stable isotope, stomach content, and genetic analyses of prey, to evaluate differences in lionfish trophic interactions and habitat use patterns. Our results show that populations may have increased in San Salvador during the last 4&nbsp;years, and that there is a strong similarity in body size between habitats, stark differences in prey items, and no apparent overlap in the use of habitat and/or food resources. These results suggest that there is not evidence an for ontogenetic shift from mangroves to reefs, and support other studies that propose lionfish are opportunistic forages with little movement across habitats.</span></p>","language":"English","publisher":"Wiley","doi":"10.1111/maec.12114","usgsCitation":"Pimiento, C., Nifong, J.C., Hunter, M.E., Monaco, E., and Silliman, B.R., 2015, Habitat use patterns of the invasive red lionfish <i>Pterois volitans</i>: a comparison between mangrove and reef systems in San Salvador, Bahamas: Marine Ecology Progress Series, v. 36, no. 1, p. 28-37, https://doi.org/10.1111/maec.12114.","productDescription":"10 p.","startPage":"28","endPage":"37","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-044197","costCenters":[{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true}],"links":[{"id":300163,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Bahamas","state":"San Salvador","otherGeospatial":"Graham's Harbor, Pigeon Creek","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -74.47494506835938,\n              24.119181784645278\n            ],\n            [\n              -74.47494506835938,\n              24.12826860596954\n            ],\n            [\n              -74.4594955444336,\n              24.12826860596954\n            ],\n            [\n              -74.4594955444336,\n              24.119181784645278\n            ],\n            [\n              -74.47494506835938,\n              24.119181784645278\n            ]\n          ]\n        ]\n      }\n    },\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -74.49348449707031,\n              23.958018806761356\n            ],\n            [\n              -74.49348449707031,\n              23.966175871265044\n            ],\n            [\n              -74.4824981689453,\n              23.966175871265044\n            ],\n            [\n              -74.4824981689453,\n              23.958018806761356\n            ],\n            [\n              -74.49348449707031,\n              23.958018806761356\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"36","issue":"1","publishingServiceCenter":{"id":8,"text":"Raleigh PSC"},"noUsgsAuthors":false,"publicationDate":"2013-11-18","publicationStatus":"PW","scienceBaseUri":"554c7ea9e4b082ec54128481","contributors":{"authors":[{"text":"Pimiento, Catalina","contributorId":140625,"corporation":false,"usgs":false,"family":"Pimiento","given":"Catalina","email":"","affiliations":[{"id":13453,"text":"University of Florida, Gainesville, FL","active":true,"usgs":false}],"preferred":false,"id":546341,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Nifong, James C.","contributorId":140624,"corporation":false,"usgs":false,"family":"Nifong","given":"James","email":"","middleInitial":"C.","affiliations":[{"id":13453,"text":"University of Florida, Gainesville, FL","active":true,"usgs":false}],"preferred":false,"id":546340,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hunter, Margaret E. 0000-0002-4760-9302 mhunter@usgs.gov","orcid":"https://orcid.org/0000-0002-4760-9302","contributorId":140622,"corporation":false,"usgs":true,"family":"Hunter","given":"Margaret","email":"mhunter@usgs.gov","middleInitial":"E.","affiliations":[{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true}],"preferred":true,"id":546338,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Monaco, Eric","contributorId":140623,"corporation":false,"usgs":false,"family":"Monaco","given":"Eric","email":"","affiliations":[{"id":13453,"text":"University of Florida, Gainesville, FL","active":true,"usgs":false}],"preferred":false,"id":546339,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Silliman, Brian R.","contributorId":53659,"corporation":false,"usgs":true,"family":"Silliman","given":"Brian","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":546342,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

The organic matter-rich Marcellus Shale is present throughout most of the synclinorium, being absent only where it has been eroded from the crest of anticlines. Geochemical analyses of outcrop and well drill-cuttings samples indicate that variable levels of hydrocarbons have been generated and expelled from the kerogen originally in place in the mudstone.

However, gas-hydrate recovery is both a scientific and a technical challenge and much remains to be learned about the geologic, engineering, and economic factors controlling the ultimate energy resource potential of gas hydrate. The amount of natural gas contained in the world&rsquo;s gas-hydrate accumulations is enormous, but these estimates are speculative and range over three orders of magnitude from about 2,800 to 8,000,000 trillion cubic meters of gas. By comparison, conventional natural gas accumulations (reserves and undiscovered, technically recoverable resources) for the world are estimated at approximately 440 trillion cubic meters. Gas recovery from gas hydrate is hindered because the gas is in a solid form and because gas hydrate commonly occurs in remote Arctic and deep marine environments. Proposed methods of gas recovery from gas hydrate generally deal with disassociating or &ldquo;melting&rdquo; in situ gas hydrate by heating the reservoir beyond the temperature of gas-hydrate formation, or decreasing the reservoir pressure below hydrate equilibrium. The pace of energy-related gas hydrate assessment projects has accelerated over the past several years.</p>\n<p>The Indian National Gas Hydrate Program Expedition 01 was designed to study the gas-hydrate occurrences off the Indian Peninsula and along the Andaman convergent margin with special emphasis on understanding the geologic and geochemical controls on the occurrence of gas hydrate in these two diverse settings. During Indian National Gas Hydrate Program Expedition 01, dedicated gas-hydrate coring, drilling, and downhole logging operations were conducted from 28 April 2006 to 19 August

Improved understanding of trends in land-cover change and the ability to forecast land-cover change that is consistent with these trends will be a key component of efforts to accommodate local military-mission imperatives while also promoting sustainable economic growth throughout the 13-county study area. The study had three principal objectives:</span><br /><br /><span>&nbsp;&nbsp;&nbsp;&nbsp;1.&nbsp;&nbsp;Evaluate historic changes in population and land cover for the period 1992&ndash;2006 using both

Understanding the relationships between environmental variables and quagga mussels during the early stages of invasion will help management strategies and allow researchers to predict patterns of future invasions. Quagga mussels were detected in Lake Mead, NV/AZ in 2007, we monitored early invasion dynamics in 3 basins (Boulder Basin, Las Vegas Bay, Overton Arm) bi-annually from 2008-2011. Mean quagga density increased over time during the first year of monitoring and stabilized for the subsequent two years at the whole-lake scale (8 to 132 individuals·m-2, geometric mean), in Boulder Basin (73 to 875 individuals·m-2), and in Overton Arm(2 to 126 individuals·m-2). In Las Vegas Bay, quagga mussel density was low (9 to 44 individuals·m-2), which was correlated with high sediment metal concentrations and warmer (> 30°C) water temperatures associated with that basin. Carbon content in the sediment increased with depth in Lake Mead and during some sampling periods quagga density was also positively correlated with depth, but more research is required to determine the significance of this interaction. Laboratory growth experiments suggested that food quantity may limit quagga growth in Boulder Basin, indicating an opportunity for population expansion in this basin if primary productivity were to increase, but was not the case in Overton Arm. Overall quagga mussel density in Lake Mead is highly variable and patchy, suggesting that temperature, sediment size, and sediment metal concentrations, and sediment carbon content all contribute to mussel distribution patterns. Quagga mussel density in the soft sediment of Lake Mead expanded during initial colonization, and began to stabilize approximately 3 years after the initial invasion.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Biology and management of invasive Quagga and Zebra Mussels in the western United States","language":"English","publisher":"CRC Press","collaboration":"University of Nevada-Reno; Desert Research Institute; National Park Service","usgsCitation":"Caldwell, T.J., Rosen, M.R., Chandra, S., Acharya, K., Caires, A.M., Davis, C.J., Thaw, M., and Webster, D.M., 2015, Temporal and basin-specific population trends of quagga mussels on soft sediment of a multi-basin reservoir, chap. <i>of</i> Biology and management of invasive Quagga and Zebra Mussels in the western United States, p. 33-52.","productDescription":"20 p.","startPage":"33","endPage":"52","ipdsId":"IP-052767","costCenters":[{"id":509,"text":"Office of the Associate Director for Water","active":true,"usgs":true}],"links":[{"id":328422,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":306642,"type":{"id":15,"text":"Index Page"},"url":"https://www.crcpress.com/Biology-and-Management-of-Invasive-Quagga-and-Zebra-Mussels-in-the-Western/Wong-Gerstenberger/9781466595613"}],"publishingServiceCenter":{"id":9,"text":"Reston PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"57d28bafe4b0571647d0f94a","contributors":{"authors":[{"text":"Caldwell, Timothy J","contributorId":146463,"corporation":false,"usgs":false,"family":"Caldwell","given":"Timothy","email":"","middleInitial":"J","affiliations":[{"id":16704,"text":"University of Nevada - Reno","active":true,"usgs":false}],"preferred":false,"id":567980,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Rosen, Michael R. 0000-0003-3991-0522 mrosen@usgs.gov","orcid":"https://orcid.org/0000-0003-3991-0522","contributorId":495,"corporation":false,"usgs":true,"family":"Rosen","given":"Michael","email":"mrosen@usgs.gov","middleInitial":"R.","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":true,"id":567979,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Chandra, Sudeep","contributorId":33195,"corporation":false,"usgs":false,"family":"Chandra","given":"Sudeep","affiliations":[{"id":12742,"text":"University of Nevada Reno","active":true,"usgs":false}],"preferred":false,"id":567981,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Acharya, Kumud","contributorId":146464,"corporation":false,"usgs":false,"family":"Acharya","given":"Kumud","email":"","affiliations":[{"id":16138,"text":"Desert Research Institute","active":true,"usgs":false}],"preferred":false,"id":567982,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Caires, Andrea M","contributorId":146465,"corporation":false,"usgs":false,"family":"Caires","given":"Andrea","email":"","middleInitial":"M","affiliations":[{"id":16704,"text":"University of Nevada - Reno","active":true,"usgs":false}],"preferred":false,"id":567983,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Davis, Clinton J.","contributorId":146466,"corporation":false,"usgs":false,"family":"Davis","given":"Clinton","email":"","middleInitial":"J.","affiliations":[{"id":16704,"text":"University of Nevada - Reno","active":true,"usgs":false}],"preferred":false,"id":567984,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Thaw, Melissa","contributorId":146467,"corporation":false,"usgs":false,"family":"Thaw","given":"Melissa","email":"","affiliations":[{"id":16138,"text":"Desert Research Institute","active":true,"usgs":false}],"preferred":false,"id":567985,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Webster, Daniel M. webster@usgs.gov","contributorId":3529,"corporation":false,"usgs":true,"family":"Webster","given":"Daniel","email":"webster@usgs.gov","middleInitial":"M.","affiliations":[{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true}],"preferred":true,"id":567986,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

As world demand for REEs increases, critical shortages are expected. Due to the retention of REEs during coal combustion, coal fly ash is increasingly considered a potential resource. Previous studies have demonstrated that coal fly ash is variably enriched in REEs relative to feed coal (e.g, Seredin and Dai, 2012) and that enrichment increases with decreasing size fractions (Blissett et al., 2014). In order to further explore the REE resource potential of coal ash, and determine the partitioning behavior of REE as a function of grain size, we studied whole coal and fly ash size-fractions collected from three U.S commercial-scale coal-fired generating stations burning Appalachian or Powder River Basin coal. Whole fly ash was separated into , 5 um, to 5 to 10 um and 10 to 100 um particle size fractions by mechanical shaking using trace-metal clean procedures. In these samples REE enrichments in whole fly ash ranges 5.6 to 18.5 times that of feedcoals. Partitioning results for size separates relative to whole coal and whole fly ash will also be reported.&nbsp;</p>","conferenceTitle":"World of Coal Ash","conferenceDate":"May 5-7, 2015","conferenceLocation":"Nashville, TN","language":"English","usgsCitation":"Scott, C., Deonarine, A., Kolker, A., Adams, M., and Holland, J., 2015, Size distribution of rare earth elements in coal ash, World of Coal Ash, Nashville, TN, May 5-7, 2015, 9 p.","productDescription":"9 p.","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-065352","costCenters":[{"id":241,"text":"Eastern Energy Resources Science Center","active":true,"usgs":true}],"links":[{"id":313254,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"publishingServiceCenter":{"id":9,"text":"Reston PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"568ba5e1e4b0e7594ee776c7","contributors":{"authors":[{"text":"Scott, Clint 0000-0003-2778-2711 clintonscott@usgs.gov","orcid":"https://orcid.org/0000-0003-2778-2711","contributorId":5332,"corporation":false,"usgs":true,"family":"Scott","given":"Clint","email":"clintonscott@usgs.gov","affiliations":[{"id":241,"text":"Eastern Energy Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":546048,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Deonarine, Amrika adeonarine@usgs.gov","contributorId":5072,"corporation":false,"usgs":true,"family":"Deonarine","given":"Amrika","email":"adeonarine@usgs.gov","affiliations":[{"id":241,"text":"Eastern Energy Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":546049,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kolker, Allan 0000-0002-5768-4533 akolker@usgs.gov","orcid":"https://orcid.org/0000-0002-5768-4533","contributorId":643,"corporation":false,"usgs":true,"family":"Kolker","given":"Allan","email":"akolker@usgs.gov","affiliations":[{"id":241,"text":"Eastern Energy Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":546050,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Adams, Monique madams@usgs.gov","contributorId":1231,"corporation":false,"usgs":true,"family":"Adams","given":"Monique","email":"madams@usgs.gov","affiliations":[{"id":211,"text":"Crustal Geophysics and Geochemistry Science Center","active":true,"usgs":true}],"preferred":true,"id":546051,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Holland, James","contributorId":354037,"corporation":false,"usgs":true,"family":"Holland","given":"James","affiliations":[{"id":241,"text":"Eastern Energy Resources Science Center","active":true,"usgs":true}],"preferred":false,"id":935014,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Ordinary least-squares regression techniques were used to determine the best explanatory variables for the regression equations. Traditional map-based explanatory variables were compared to variables requiring field measurements. Two field-based variables&mdash;culvert rust lines and bankfull channel widths&mdash;either were not commonly found or did not explain enough of the variability in the peak flows to warrant inclusion in the equations. The best explanatory variables were drainage area and percent basin wetlands; values for these variables were determined with a geographic information system. Generalized least-squares regression was used with these two variables to determine the equation coefficients and estimates of accuracy for the final

Wetlands rely on organic material and inorganic sediment deposition to maintain their elevation relative to sea level. The U.S. Geological Survey performed observational deployments to measure suspended-sediment concentration and water flow rates in the tidal channels of the wetlands in the Rachel Carson National Wildlife Refuge in Wells, Maine. The objective was to characterize the sediment-transport mechanisms that contribute to the net sediment budget of the wetland complex. We deployed a meteorological tower, optical turbidity sensors, and acoustic velocity meters at sites on Stephens Brook and the Ogunquit River between March 27 and December 9, 2013. This report presents the time-series oceanographic and atmospheric data collected during those field studies. The oceanographic parameters include water velocity, depth, turbidity, salinity, temperature, and pH. The atmospheric parameters include wind direction, speed, and gust; air temperature; air pressure; relative humidity; short wave radiation; and photosynthetically active radiation.</span></p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr20151072","usgsCitation":"Montgomery, E., Ganju, N., Dickhudt, P.,

Possible explanations for this high oxidation state are that the transfer of fluids during the subduction process results in direct oxidation of the sub-arc mantle wedge, or that oxidation is caused by the effect of later crustal processes, including protracted fractionation and degassing of volatile-rich magmas. This study sets out to investigate the effect of disequilibrium crustal processes that may involve coupled changes in H</span><sub>2</sub><span>O content and Fe oxidation state, by examining the degassing and hydration of sulphur-free rhyolites. We show that experimentally hydrated melts record strong increases in Fe</span><sup>3+</sup><span>/&sum;Fe with increasing H</span><sub>2</sub><span>O concentration as a result of changes in water activity. This is relevant for the passage of H</span><sub>2</sub><span>O-undersaturated melts from the deep crust towards shallow crustal storage regions, and raises the possibility that vertical variations in&nbsp;</span><i>f</i><span>O</span><sub>2</sub><span>&nbsp;might develop within arc crust. Conversely, degassing experiments produce an increase in Fe</span><sup>3+</sup><span>/&sum;Fe with decreasing H</span><sub>2</sub><span>O concentration. In this case the oxidation is explained by loss of H</span><sub>2</sub><span>&nbsp;as well as H</span><sub>2</sub><span>O into bubbles during decompression, consistent with thermodynamic modelling, and is relevant for magmas undergoing shallow degassing en route to the surface. We discuss these results in the context of the possible controls on&nbsp;</span><i>f</i><span>O</span><sub>2</sub><span>&nbsp;during the generation, storage and ascent of magmas in arc settings, in particular considering the timescales of equilibration relative to observation as this affects the quality of the petrological record of magmatic&nbsp;</span><i>f</i><span>O</span><sub>2</sub><span>.</span></p>","language":"English","publisher":"Oxford University Press","publisherLocation":"Oxford","doi":"10.1093/petrology/egv017","usgsCitation":"Humphreys, M.C., Brooker, R., Fraser, D., Burgisser, A., Mangan, M.T., and McCammon, C., 2015, Coupled interactions between volatile activity and Fe oxidation state during arc crustal processes: Journal of Petrology, p. 1-20, https://doi.org/10.1093/petrology/egv017.","productDescription":"20 p.","startPage":"1","endPage":"20","numberOfPages":"20","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-055270","costCenters":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":472101,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1093/petrology/egv017","text":"Publisher Index Page"},{"id":306784,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationDate":"2015-05-06","publicationStatus":"PW","scienceBaseUri":"57f7ef2ae4b0bc0bec09ef46","contributors":{"authors":[{"text":"Humphreys, Madeleine C.S.","contributorId":103199,"corporation":false,"usgs":true,"family":"Humphreys","given":"Madeleine","email":"","middleInitial":"C.S.","affiliations":[],"preferred":false,"id":566661,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Brooker, R","contributorId":146223,"corporation":false,"usgs":false,"family":"Brooker","given":"R","email":"","affiliations":[{"id":16635,"text":"Bristol University","active":true,"usgs":false}],"preferred":false,"id":566662,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Fraser, D.C.","contributorId":35732,"corporation":false,"usgs":true,"family":"Fraser","given":"D.C.","email":"","affiliations":[],"preferred":false,"id":566663,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Burgisser, A","contributorId":146224,"corporation":false,"usgs":false,"family":"Burgisser","given":"A","affiliations":[{"id":16636,"text":"CNRS","active":true,"usgs":false}],"preferred":false,"id":566664,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Mangan, Margaret T. 0000-0002-5273-8053 mmangan@usgs.gov","orcid":"https://orcid.org/0000-0002-5273-8053","contributorId":3343,"corporation":false,"usgs":true,"family":"Mangan","given":"Margaret","email":"mmangan@usgs.gov","middleInitial":"T.","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":615,"text":"Volcano Hazards Program","active":true,"usgs":true},{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":566660,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"McCammon, C","contributorId":146225,"corporation":false,"usgs":false,"family":"McCammon","given":"C","email":"","affiliations":[{"id":13489,"text":"Bayerisches Geoinstitut, Universität Bayreuth, 95440 Bayreuth, Germany","active":true,"usgs":false}],"preferred":false,"id":566665,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

We examined movement decisions of sea lampreys (</span><i>Petromyzon marinus</i><span>&nbsp;L.) exposed to a conspecific and an environmental cue during pre-spawning migration. Specifically, we predicted that the mature male-released sex pheromone 3-keto petromyzonol sulfate (3kPZS) will outweigh the locomotor inhibiting effects of cold stream temperature (less than 15&deg;C). Using large-scale stream bioassays, we found that 3kPZS elicits an increase (more than 40%) in upstream movement of pre-spawning lampreys when the water temperatures were below 15&deg;C. Both warming temperatures and conspecific cues increase upstream movement when the water temperature rose above 15&deg;C. These patterns define an interaction between abiotic and conspecific cues in modulating animal decision-making, providing an example of the hierarchy of contradictory information.</span></p>","language":"English","publisher":"Royal Society Publishing","publisherLocation":"London","doi":"10.1098/rsos.150009","usgsCitation":"Brant, C., Li, K., Johnson, N., and Li, W., 2015, A pheromone outweighs temperature in influencing migration of sea lamprey: Royal Society Open Science, v. 2, p. 1-7, https://doi.org/10.1098/rsos.150009.","productDescription":"7 p.","startPage":"1","endPage":"7","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-064542","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":472102,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1098/rsos.150009","text":"Publisher Index Page"},{"id":308167,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"2","publishingServiceCenter":{"id":6,"text":"Columbus PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"55fa92ace4b05d6c4e501a40","contributors":{"authors":[{"text":"Brant, Cory O.","contributorId":52872,"corporation":false,"usgs":true,"family":"Brant","given":"Cory O.","affiliations":[],"preferred":false,"id":564077,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Li, Ke","contributorId":172267,"corporation":false,"usgs":false,"family":"Li","given":"Ke","email":"","affiliations":[],"preferred":false,"id":640106,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Johnson, Nicholas S. njohnson@usgs.gov","contributorId":145449,"corporation":false,"usgs":true,"family":"Johnson","given":"Nicholas S.","email":"njohnson@usgs.gov","affiliations":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"preferred":false,"id":564076,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Li, Weiming","contributorId":65440,"corporation":false,"usgs":true,"family":"Li","given":"Weiming","affiliations":[],"preferred":false,"id":564079,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

They have been suggested to be good analogs, however, for some circular features on Mars. BRSs are found where Pleistocene floods scoured the Columbia River Basin, stripping off the uppermost part of the Miocene Columbia River Basalt Group and exposing structures that were previously embedded in the lava. The &ldquo;Odessa Craters,&rdquo; near Odessa, WA, are 50&ndash;500-m-wide BRSs that are comprised of discontinuous, concentric outcrops of subvertically-jointed basalt and autointrusive dikes. Detailed field investigation of the Odessa Craters in planform and a cross-sectional exposure of a similar structure above Banks Lake, WA, lead us to propose that BRSs formed by concurrent phreatovolcanism and lava flow inflation. In this model, phreatovolcanic (a.k.a., &ldquo;rootless&rdquo;) cones formed on a relatively thin, active lava flow; the lava flow inflated around the cones, locally inverting topography; tensile stresses caused concentric fracturing of the lava crust; lava from within the molten interior of the flow exploited the fractures and buried the phreatovolcanic cones; and subsequent erosive floods excavated the structures. Another population of BRSs near Tokio Station, WA, consists of single-ringed, raised-rimmed structures that are smaller and more randomly distributed than the Odessa Craters. We find evidence for a phreatovolcanic component to the origin as well, and hypothesize that they are either flood-eroded phreatovolcanic cones or Odessa Crater-like BRSs. This work indicates that BRSs are not good analogs to the features on Mars because the martian features are found on the uneroded surfaces. Despite this, the now superseded concepts for BRS formation are useful for understanding the formation of the martian features.</p>","conferenceTitle":"45th Annual Binghamton Geomorphology Symposium","conferenceDate":"September 12-14, 2014","conferenceLocation":"Knoxville, TN","language":"English","publisher":"Elsevier","doi":"10.1016/j.geomorph.2014.06.027","usgsCitation":"Keszthelyi, L.P., and Jaeger, W.L., 2015, A field investigation of the basaltic ring structures of the Channeled Scabland and the relevance to Mars: Geomorphology, v. 240, p. 34-43, https://doi.org/10.1016/j.geomorph.2014.06.027.","productDescription":"10 p.","startPage":"34","endPage":"43","numberOfPages":"10","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-050656","costCenters":[{"id":131,"text":"Astrogeology Science Center","active":true,"usgs":true}],"links":[{"id":300125,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Washington","otherGeospatial":"Channeled Scabland, Mars, Odessa Craters","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -119.1302490234375,\n              47.92554522341879\n            ],\n            [\n              -119.21539306640626,\n              47.88872266659918\n            ],\n            [\n              -119.34722900390625,\n              47.635783590864854\n            ],\n            [\n              -118.7677001953125,\n              47.29040793812928\n            ],\n            [\n              -118.2843017578125,\n              47.12808212013255\n            ],\n            [\n              -118.11126708984375,\n              47.21397145824759\n            ],\n            [\n              -119.1302490234375,\n              47.92554522341879\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"240","publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"554b2d17e4b082ec54127142","contributors":{"authors":[{"text":"Keszthelyi, Laszlo P. 0000-0003-1879-4331 laz@usgs.gov","orcid":"https://orcid.org/0000-0003-1879-4331","contributorId":227,"corporation":false,"usgs":true,"family":"Keszthelyi","given":"Laszlo","email":"laz@usgs.gov","middleInitial":"P.","affiliations":[{"id":131,"text":"Astrogeology Science Center","active":true,"usgs":true}],"preferred":true,"id":546250,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Jaeger, Windy L.","contributorId":61679,"corporation":false,"usgs":true,"family":"Jaeger","given":"Windy","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":546251,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

For this study, the extent of the Northern Atlantic Coastal Plain falls within areas of the States of New York, New Jersey, Delaware, Maryland, Virginia, and North Carolina. The irrigation dataset maps about 271,900 acres operated primarily under center-pivot irrigation in 57 counties. Manual digitizing was performed against aerial imagery in a process where operators used observable center-pivot irrigation signatures&mdash;such as irrigation arms, concentric wheel paths through cropped areas, and differential colors&mdash;to identify and map irrigated areas. The aerial imagery used for digitizing came from a variety of sources and seasons. The imagery contained a variety of spatial resolutions and included online imagery from the U.S. Department of Agriculture National Agricultural Imagery Program, Microsoft Bing Maps, and the Google Maps mapping service. The dates of the source images ranged from 2010 to 2012 for the U.S. Department of Agriculture imagery, whereas maps from the other mapping services were from 2013.</p>\n<p>Most of the irrigation in the study area is on the Delmarva Peninsula, where about 75 percent of the total acreage was delineated and where corn and soy bean are the main crops. The methods used to develop this dataset focused primarily on identifying center-pivot irrigation systems. In some instances (such as in in Suffolk County, New York), irrigated rectangular fields were observed through the aerial imagery, and these were included within the dataset. Other irrigation methods included subsurface drip and flood irrigation, which are commonly used on vegetable crops such as peppers and tomatoes and forage crops such as alfalfa in parts the western United States. Some fruit and nursery stock crops also use subsurface drip and flood irrigation. Drip irrigation is especially apparent in New Jersey where large plantings of truck crops are common.

For over ten years, BLM in Arizona has used the simultaneous double-observer method of recording wild burros during aerial surveys and has reported population estimates for those surveys that come from two formulations of a Lincoln-Petersen type of analysis (Graham and Bell, 1989). In this report, I provide those same two types of burro population analysis for 2014 aerial survey data from six herd management areas (HMAs) in Arizona, California, Nevada, and Utah. I also provide burro population estimates based on a different form of simultaneous double-observer analysis, now in widespread use for wild horse surveys that takes into account the potential effects on detection probability of sighting covariates including group size, distance, vegetative cover, and other factors (Huggins, 1989, 1991). The true number of burros present in the six areas surveyed was not known, so population estimates made with these three types of analyses cannot be directly tested for accuracy in this report. I discuss theoretical reasons why the Huggins (1989, 1991) type of analysis should provide less biased estimates of population size than the Lincoln-Petersen analyses and why estimates from all forms of double-observer analyses are likely to be lower than the true number of animals present in the surveyed areas. I note reasons why I suggest using burro observations made at all available distances in analyses, not only those within 200 meters of the flight path. For all analytical methods, small sample sizes of observed groups can be problematic, but that sample size can be increased over time for Huggins (1989, 1991) analyses by pooling observations. I note ways by which burro population estimates could be tested for accuracy when there are radio-collared animals in the population or when there are simultaneous double-observer surveys before and after a burro gather and removal.</span></p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr20151084","usgsCitation":"Griffin, P., 2015,

This report, prepared in cooperation by the U.S. Geological Survey and the city of Wichita, Kansas, summarizes Little Arkansas River (source-water for artificial recharge) and<i>Equus</i>&nbsp;Beds aquifer water quality before (1995&ndash;2006) and during (2007&ndash;2012) Artificial Storage and Recovery Phase I recharge. Additionally, aquifer water-quality distribution maps are presented and water-quality changes associated with Phase I recharge timing are described.</p>\n<p>Computed chloride concentrations in the Little Arkansas River exceeded the Federal secondary maximum contaminant level (SMCL) about 20 percent of the time during 1999 through 2012, primarily during low-flow conditions. Groundwater chloride concentrations during 2001 through 2012 exceeded the SMCL in about 6 percent of shallow wells and 7 percent of deep wells, primarily near Burrton, Kansas and along the Arkansas River. Nearly all surface water nitrate plus nitrite concentrations during 1995 through 2012 were less than the Federal maximum contaminant level (MCL); groundwater nitrate plus nitrite concentrations exceeded the MCL in about 16 percent of shallow groundwater samples and were minimal in the deeper parts of the aquifer. Several trace elements frequently exceeded drinking water criteria, including arsenic, iron, and manganese.</p>\n<p>Recharge activities at Phase I recharge wells have not resulted in substantial effects on groundwater quality in the area, likely because the total amount of water recharged is relatively small (1 billion gallons) compared to aquifer storage volume (greater than 990 billion gallons in winter 2012). The eastward movement of the Burrton chloride plume is likely being slowed by a line of recharge locations associated with Phase I; however, chloride concentrations in deep groundwater still advanced to less than one half mile from the central part of the study area. Water-quality constituents of concern (major ions, nutrients, trace elements, triazine herbicides, and fecal indicator bacteria) have not increased substantially and are likely more affected by climatological (natural recharge by precipitation) and natural (geochemical oxidation/reduction, metabolic and decay rates) processes than artificial recharge. Arsenic remains a water-quality constituent of concern because of natural and continued persistence of concentrations exceeding the Federal maximum contaminant level of 10 micrograms per liter, especially in the deeper parts of the<i>Equus</i>&nbsp;Beds aquifer.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston,

The watershed comprises two smaller subareas, the Benson subarea and the Narrows-Redington subarea. Early 21st century projections for heavy population growth in the watershed have not yet become a reality, but increased groundwater withdrawals could have undesired consequences - such as decreased base flow to the San Pedro River, and groundwater-level declines - that would lead to the need to deepen existing wells. This report describes the hydrology, hydrochemistry, water quality, and development of a groundwater budget for the middle San Pedro Watershed, focusing primarily on the elements of groundwater movement that could be most useful for the development of a groundwater model</p><p>Precipitation data from Tombstone, Arizona, and base flow at the stream-gaging station on the San Pedro River at Charleston both show relatively dry periods during the 1960s through the mid-1980s and in the mid-1990s to 2009, and wetter periods from the mid-1980s through the mid-1990s. Water levels in four out of five wells near the mountain fronts show cyclical patterns of recharge, with rates of recharge greatest in the early 1980s through the mid-1990s. Three wells near the San Pedro River recorded their lowest levels during the 1950s to the mid-1960s. The water-level record from one well, completed in the confined part of the coarse-grained lower basin fill, showed a decline of approximately 21 meters.</p><p>Annual flow of the San Pedro River, measured at the Charleston and Redington gages, has decreased since the 1940s. The median annual streamflow and base flow at the gaging station on the river near Tombstone has decreased by 50 percent between the periods 1968–1986 and 1997–2009. Estimates of streamflow infiltration along the San Pedro River during 1914–2009 have decreased 44 percent, with the largest decreases in the months June–October in the Benson subarea. In the Narrows-Redington subarea, streamflow infiltration has decreased about 65 percent during 1914–2009.</p><p>The average annual outflow (27.6 hm<sup>3</sup>/year [cubic hectometers per year]) from the Benson subarea aquifer for water years 2001 through 2009 exceeded the inflows (20.0 hm<sup>3</sup>/ yr) by 7.60 hm<sup>3</sup>/yr. In the Narrows-Redington subarea for the same period, the average annual outflow (15.7 hm<sup>3</sup>/yr) from the aquifer system exceeded the inflows (13.8 hm<sup>3</sup>/yr) by nearly 2 hm<sup>3</sup>/yr. The largest withdrawals of groundwater in both subareas are for irrigation; these withdrawals peaked in 1973 and have been steadily decreasing since then. Recharge from streamflow infiltration exceeded recharge from the mountain-front and from ephemeral channels in the Benson subarea. In the Narrows-Redington subarea, however, recharge from mountain-front and ephemeral channel recharge exceeded recharge from streamflow infiltration. Evapotranspiration by phreatophytes accounts for the largest outflow of groundwater for both subareas—78 percent of the outflow in the Narrows-Redington subarea and 62 percent of the outflow in the Benson subarea.</p><p>Precipitation, surface-water, and groundwater chemistry and isotope data indicated the relative age and residence time of groundwater, the amount of interaction between geologic sources and groundwater, and how recharge elevation and season were related to the presence of modern water.

The shorelines used in the analysis were generated from georeferenced historical aerial imagery and are used to develop shoreline change rates for Hatteras Island, from Oregon Inlet to Cape Hatteras. A total of 14 dates of aerial photographs ranging from 1978 through 2002 were obtained from the U.S. Army Corp of Engineers Field Research Facility in Duck, North Carolina, and scanned to generate digital imagery. The digital imagery was georeferenced and high water line shorelines (interpreted from the wet/dry line) were digitized from each date to produce a time series of shorelines for the study area. Rates of shoreline change were calculated for three periods: the full span of the time series, 1978 through 2002, and two approximately decadal subsets, 1978&ndash;89 and 1989&ndash;2002.</span></p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr20151002","usgsCitation":"Hapke, C.J., and Henderson, R.,
