While attention has focused on global climate change and how it could intensify key elements of the water cycle such as precipitation and river discharge, it is the conjunction of geophysical and socioeconomic forces that shapes human sensitivity and risks to weather extremes. We demonstrate here the use of high-resolution geophysical and population datasets together with documentary reports of rainfall-induced damage across South America over a multi-decadal, retrospective time domain (1960&ndash;2000). We define and map extreme precipitation&nbsp;</span><i>hazard</i><span>,&nbsp;</span><i>exposure</i><span>,&nbsp;</span><i>affected</i><span>populations,&nbsp;</span><i>vulnerability</i><span>&nbsp;and&nbsp;</span><i>risk</i><span>, and use these variables to analyse the impact of floods as a water security issue. Geospatial experiments uncover major sources of risk from natural climate variability and population growth, with change in climate extremes bearing a minor role. While rural populations display greatest relative sensitivity to extreme rainfall, urban settings show the highest rates of increasing risk. In the coming decades, rapid urbanization will make South American cities the focal point of future climate threats but also an opportunity for reducing vulnerability, protecting lives and sustaining economic development through both traditional and ecosystem-based disaster risk management systems.</span></p>","language":"English","publisher":"Royal Society

The King Rail (</span><i>Rallus elegans</i><span>) is a wetland bird of high conservation concern in the United States, but little is known about its movements, habitats, or demography. King Rails (</span><i>n</i><span>&nbsp;= 34) were captured during the 2010&ndash;2011 breeding seasons in the coastal marshes of southwest Louisiana and southeast Texas. Radio telemetry and direct habitat surveys of King Rail locations were conducted to estimate home ranges and microhabitat selection. Within home ranges, King Rails selected for greater plant species richness and comparatively greater coverage of&nbsp;</span><i>Phragmites australis</i><span>,&nbsp;</span><i>Typha</i><span>&nbsp;spp., and&nbsp;</span><i>Schoenoplectus robustus</i><span>. King Rails were found closer to open water compared to random locations placed 50 m from King Rail locations. Home ranges (</span><i>n</i><span>&nbsp;= 22) varied from 0.8&ndash;32.8 ha and differed greatly among sites. Home range size did not vary by year or sex; however, increased open water, with a maximum of 29% observed in the study, was correlated with smaller home ranges. Breeding season cumulative survivorship was 89% &plusmn; 22% in 2010 and 61% &plusmn; 43% in 2011, which coincided with a drought. With an equal search effort, King Rail chicks and juveniles observed in May-June decreased from 110 in 2010 to only 16 in the drier year of 2011. The findings show King Rail used marsh with &le; 29% open water and had smaller home ranges when open water was more abundant.</span></p>","language":"English","publisher":"The Waterbird Society","doi":"10.1675/063.036.0309","usgsCitation":"Pickens, B.A., and King, S.L., 2013, Microhabitat selection, demography, and correlates of home range size for the King Rail (<i>Rallus elegans</i>): Waterbirds, v. 36, no. 3, p. 319-329, https://doi.org/10.1675/063.036.0309.","productDescription":"11 p.","startPage":"319","endPage":"329","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-041384","costCenters":[{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true}],"links":[{"id":305885,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Louisiana, Texas","otherGeospatial":"Cameron Prairie National Wildlife Refuge; JD Murphree Wildlife Management Area; McFaddin National Wildlife Refuge","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -93.11187744140625,\n              29.864465259258\n            ],\n            [\n              -93.11187744140625,\n              29.973970240516614\n            ],\n            [\n              -92.98004150390625,\n              29.973970240516614\n            ],\n            [\n              -92.98004150390625,\n              29.864465259258\n            ],\n            [\n              -93.11187744140625,\n              29.864465259258\n            ]\n          ]\n        ]\n      }\n    },\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -94.13154602050781,\n              29.82813541108161\n            ],\n            [\n              -94.13154602050781,\n              29.956719300555342\n            ],\n            [\n              -93.95027160644531,\n              29.956719300555342\n            ],\n            [\n              -93.95027160644531,\n              29.82813541108161\n            ],\n            [\n              -94.13154602050781,\n              29.82813541108161\n            ]\n          ]\n        ]\n      }\n    },\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -94.48791503906249,\n              29.5232805008286\n            ],\n            [\n              -94.48791503906249,\n              29.740532166753606\n            ],\n            [\n              -94.16656494140625,\n              29.740532166753606\n            ],\n            [\n              -94.16656494140625,\n              29.5232805008286\n            ],\n            [\n              -94.48791503906249,\n              29.5232805008286\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"36","issue":"3","publishingServiceCenter":{"id":8,"text":"Raleigh PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"55b0beaee4b09a3b01b5309c","contributors":{"authors":[{"text":"Pickens, Bradley A.","contributorId":140926,"corporation":false,"usgs":false,"family":"Pickens","given":"Bradley","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":565295,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"King, Sammy L. 0000-0002-5364-6361 sking@usgs.gov","orcid":"https://orcid.org/0000-0002-5364-6361","contributorId":557,"corporation":false,"usgs":true,"family":"King","given":"Sammy","email":"sking@usgs.gov","middleInitial":"L.","affiliations":[{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true}],"preferred":true,"id":564416,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

(AECL) is evaluating the suitability of the Chalk River Laboratories (CRL) site in Ontario, situated in crystalline rock of the southwestern Grenville Province, for the possible development of an underground repository for low- and intermediate-level nuclear waste. This paper presents petrographic and trace element analyses, U–Pb zircon dating results, and Rb–Sr, U–Pb and U-series isotopic analyses of gneissic drill core samples from the deep CRG-series characterization boreholes at the CRL site. The main rock types intersected in the boreholes include hornblende–biotite (±pyroxene) gneisses of granitic to granodioritic composition, leucocratic granitic gneisses with sparse mafic minerals, and garnet-bearing gneisses with variable amounts of biotite and/or hornblende. The trace element data for whole-rock samples plot in the fields of within-plate, syn-collision, and volcanic arc-type granites in discrimination diagrams used for the tectonic interpretation of granitic rocks.</p><p id=\"sp0010\">Zircons separated from biotite gneiss and metagranite samples yielded SHRIMP-RG U–Pb ages of 1472&nbsp;±&nbsp;14 (2<i>σ</i>) and 1045&nbsp;±&nbsp;6&nbsp;Ma, respectively, in very good agreement with widespread Early Mesoproterozoic plutonic ages and Ottawan orogeny ages in the Central Gneiss Belt. The Rb–Sr, U–Pb, and Pb–Pb whole-rock errorchron apparent ages of most of the CRL gneiss samples are consistent with zircon U–Pb age and do not indicate substantial large-scale preferential element mobility during superimposed metamorphic and water/rock interaction processes. This may confirm the integrity of the rock mass, which is a positive attribute for a potential nuclear waste repository. Most<span>&nbsp;</span><sup>234</sup>U/<sup>238</sup>U activity ratios (AR) in whole rock samples are within errors of the secular equilibrium value of one, indicating that the rocks have not experienced any appreciable U loss or gain within the past 1&nbsp;Ma.

Early surveys served as reconnaissance studies only, and detailed analyses of the crustal-density structure have been limited. Here we present a new chain-wide gravity compilation that incorporates historical island surveys, recently published work on the islands of Hawai‘i, Kaua‘i, and Ni‘ihau, and >122,000 km of newly compiled marine gravity data. Positive residual gravity anomalies reflect dense intrusive bodies, allowing us to locate current and former volcanic centers, major rift zones, and a previously suggested volcano on Ka‘ena Ridge. By inverting the residual gravity data, we generate a 3-D view of the dense, intrusive complexes and olivine-rich cumulate cores within individual volcanoes and rift zones. We find that the Hāna and Ka‘ena ridges are underlain by particularly high-density intrusive material (>2.85 g/cm<sup>3</sup>) not observed beneath other Hawaiian rift zones. Contrary to previous estimates, volcanoes along the chain are shown to be composed of a small proportion of intrusive material (<30% by volume), implying that the islands are predominately built extrusively.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geophysical Research Letters","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"American Geophysical Union","usgsCitation":"Flinders, A., Ito, G., Garcia, M.O., Sinton, J.M., Kauahikaua, J., and Taylor, B., 2013, Intrusive dike complexes, cumulate cores, and the extrusive growth of Hawaiian volcanoes: Geophysical Research Letters, v. 40, no. 13, p. 3367-3373.","productDescription":"7 p.","startPage":"3367","endPage":"3373","ipdsId":"IP-048832","costCenters":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":277198,"type":{"id":15,"text":"Index Page"},"url":"https://onlinelibrary.wiley.com/doi/10.1002/grl.50633/abstract"},{"id":277224,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Hawai'i","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -178.31,18.91 ], [ -178.31,28.4 ], [ -154.81,28.4 ], [ -154.81,18.91 ], [ -178.31,18.91 ] ] ] } } ] }","volume":"40","issue":"13","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5221b0e8e4b001cbb8a34e9b","contributors":{"authors":[{"text":"Flinders, Ashton F.","contributorId":53276,"corporation":false,"usgs":true,"family":"Flinders","given":"Ashton F.","affiliations":[],"preferred":false,"id":483325,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Ito, Garrett","contributorId":67396,"corporation":false,"usgs":true,"family":"Ito","given":"Garrett","email":"","affiliations":[],"preferred":false,"id":483326,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Garcia, Michael O.","contributorId":51636,"corporation":false,"usgs":true,"family":"Garcia","given":"Michael","email":"","middleInitial":"O.","affiliations":[],"preferred":false,"id":483324,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Sinton, John M. 0000-0003-0883-5013","orcid":"https://orcid.org/0000-0003-0883-5013","contributorId":93554,"corporation":false,"usgs":true,"family":"Sinton","given":"John","email":"","middleInitial":"M.","affiliations":[],"preferred":true,"id":483328,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Kauahikaua, Jim","contributorId":47366,"corporation":false,"usgs":true,"family":"Kauahikaua","given":"Jim","email":"","affiliations":[],"preferred":false,"id":483323,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Taylor, Brian","contributorId":77448,"corporation":false,"usgs":true,"family":"Taylor","given":"Brian","email":"","affiliations":[],"preferred":false,"id":483327,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Here, the long record of sea level at Key West, FL is studied in terms of both the secular trend and the multi-scale sea level variations. This analysis is then used to explore implications for the Everglades National Park (ENP), which is recognized internationally for its ecological significance, and is the site of the largest wetland restoration project in the world. Very shallow topographic gradients (3–6 cm per km) make the region susceptible to small changes in sea level. Observations of surface water levels from a monitoring network within ENP exhibit both the long-term trends and the interannual-to-(multi)decadal variability that are observed in the Key West record. Water levels recorded at four long-term monitoring stations within ENP exhibit increasing trends approximately equal to or larger than the long-term trend at Key West. Time- and frequency-domain analyses highlight the potential influence of climate mechanisms, such as the El Niño/Southern Oscillation and the North Atlantic Oscillation (NAO), on Key West sea levels and marsh water levels, and the potential modulation of their influence by the background state of the North Atlantic Sea Surface Temperatures. In particular, the Key West sea levels are found to be positively correlated with the NAO index, while the two series exhibit high spectral power during the transition to a cold Atlantic Multidecadal Oscillation (AMO). The correlation between the Key West sea levels and the NINO3 Index reverses its sign in coincidence with a reversal of the AMO phase. Water levels in ENP are also influenced by precipitation and freshwater releases from the northern boundary of the Park. The analysis of both climate variability and climate change in such wetlands is needed to inform management practices in coastal wetland zones around the world.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Regional Environmental Change","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer","doi":"10.1007/s10113-013-0408-8","usgsCitation":"Karamperidou, C., Engel, V., Lall, U., Stabenau, E., and Smith, T.J., 2013, Implications of multi-scale sea level and climate variability for coastal resources: Regional Environmental Change, v. 13, no. 1, p. 91-100, https://doi.org/10.1007/s10113-013-0408-8.","productDescription":"10 p.","startPage":"91","endPage":"100","ipdsId":"IP-030832","costCenters":[{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true}],"links":[{"id":277223,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":277222,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10113-013-0408-8"}],"volume":"13","issue":"1","noUsgsAuthors":false,"publicationDate":"2013-02-01","publicationStatus":"PW","scienceBaseUri":"5221b0e8e4b001cbb8a34e97","contributors":{"authors":[{"text":"Karamperidou, Christina","contributorId":37630,"corporation":false,"usgs":true,"family":"Karamperidou","given":"Christina","email":"","affiliations":[],"preferred":false,"id":483356,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Engel, Victor 0000-0002-3858-7308","orcid":"https://orcid.org/0000-0002-3858-7308","contributorId":45153,"corporation":false,"usgs":true,"family":"Engel","given":"Victor","affiliations":[],"preferred":false,"id":483357,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Lall, Upmanu","contributorId":101172,"corporation":false,"usgs":true,"family":"Lall","given":"Upmanu","affiliations":[],"preferred":false,"id":483358,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Stabenau, Erik","contributorId":106784,"corporation":false,"usgs":true,"family":"Stabenau","given":"Erik","email":"","affiliations":[],"preferred":false,"id":483359,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Smith, Thomas J.

In particular, Hox10 proteins are essential to set the transition from thoracic to lumbar vertebrae because of their rib-repressing activity. In snakes, however, the thoracic region extends well into Hox10-expressing areas of the embryo, suggesting that these proteins are unable to block rib formation. Here, we show that this is not a result of the loss of rib-repressing properties by the snake proteins, but rather to a single base pair change in a Hox/Paired box (Pax)-responsive enhancer, which prevents the binding of Hox proteins. This polymorphism is also found in Paenungulata, such as elephants and manatees, which have extended rib cages. In vivo, this modified enhancer failed to respond to Hox10 activity, supporting its role in the extension of rib cages. In contrast, the enhancer could still interact with Hoxb6 and Pax3 to promote rib formation. These results suggest that a polymorphism in the Hox/Pax-responsive enhancer may have played a role in the evolution of the vertebrate spine by differently modulating its response to rib-suppressing and rib-promoting Hox proteins.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Proceedings of the National Academy of Sciences","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"National Academy of Science","doi":"10.1073/pnas.1300592110","usgsCitation":"Guerreiro, I., Nunes, A., Woltering, J.M., Casaca, A., Novoa, A., Vinagre, T., Hunter, M., Duboule, D., and Mallo, M., 2013, Role of a polymorphism in a Hox/Pax-responsive enhancer in the evolution of the vertebrate spine: Proceedings of the National Academy of Sciences, v. 110, no. 26, p. 10682-10686, https://doi.org/10.1073/pnas.1300592110.","productDescription":"5 p.","startPage":"10682","endPage":"10686","ipdsId":"IP-038658","costCenters":[{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true}],"links":[{"id":473585,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1073/pnas.1300592110","text":"Publisher Index Page"},{"id":277221,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":277220,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1073/pnas.1300592110"}],"volume":"110","issue":"26","noUsgsAuthors":false,"publicationDate":"2013-05-14","publicationStatus":"PW","scienceBaseUri":"5221b0e8e4b001cbb8a34e9f","contributors":{"authors":[{"text":"Guerreiro, Isabel","contributorId":92570,"corporation":false,"usgs":true,"family":"Guerreiro","given":"Isabel","email":"","affiliations":[],"preferred":false,"id":483303,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Nunes, Andreia","contributorId":10318,"corporation":false,"usgs":true,"family":"Nunes","given":"Andreia","email":"","affiliations":[],"preferred":false,"id":483297,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Woltering, Joost M.","contributorId":24674,"corporation":false,"usgs":true,"family":"Woltering","given":"Joost","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":483299,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Casaca, Ana","contributorId":22666,"corporation":false,"usgs":true,"family":"Casaca","given":"Ana","email":"","affiliations":[],"preferred":false,"id":483298,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Novoa, Ana","contributorId":30125,"corporation":false,"usgs":true,"family":"Novoa","given":"Ana","email":"","affiliations":[],"preferred":false,"id":483300,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Vinagre, Tania","contributorId":87846,"corporation":false,"usgs":true,"family":"Vinagre","given":"Tania","email":"","affiliations":[],"preferred":false,"id":483302,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Hunter, Margaret E. 0000-0002-4760-9302 mhunter@usgs.gov","orcid":"https://orcid.org/0000-0002-4760-9302","contributorId":4888,"corporation":false,"usgs":true,"family":"Hunter","given":"Margaret E.","email":"mhunter@usgs.gov","affiliations":[{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true}],"preferred":false,"id":483296,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Duboule, Denis","contributorId":66579,"corporation":false,"usgs":true,"family":"Duboule","given":"Denis","email":"","affiliations":[],"preferred":false,"id":483301,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Mallo, Moises","contributorId":98205,"corporation":false,"usgs":true,"family":"Mallo","given":"Moises","email":"","affiliations":[],"preferred":false,"id":483304,"contributorType":{"id":1,"text":"Authors"},"rank":9}]}}

We developed an extension of N-mixture models to account for two commonly observed phenomena in point count surveys: rarity and lack of independence induced by unmeasurable sources of variation in the detectability of individuals. Rarity increases the number of locations with zero detections in excess of those expected under simple models of abundance (e.g., Poisson or negative binomial). Correlated behavior of individuals and other phenomena, though difficult to measure, increases the variation in detection probabilities among surveys. Our extension of N-mixture models includes a hurdle model of abundance and a beta-binomial model of detectability that accounts for additional (extra-binomial) sources of variation in detections among surveys. As an illustration, we fit this model to repeated point counts of the West Indian manatee, which was observed in a pilot study using aerial surveys.

Since sinking on the morning of December 7, 1941, the hull of the USS Arizona has been slowly but steadily disappearing below the surface of Pearl Harbor. Continuous sediment coring at three of four locations around the hull of the Arizona was only partially successful, but it was sufficient to identify a varied sedimentary substrate beneath the hull. A boring near the stern reveals a thick, continuous sequence of soft, gray clay to the bottom of the boring. In contrast, borings near the bow and starboard side, below about 5 meters subbottom depth, indicate the presence of very stiff, brown clay and coral debris and an absence of soft clay. Multisensor core logger scanning of the recovered cores distinguishes the lower density of the soft, gray clay at the stern from the higher density of the stiff, brown clays and coral debris at the bow and starboard side. Uniaxial consolidation testing of the soft gray clay indicates a normally consolidated sequence, whereas the stiff, brown clay and coral debris are overconsolidated. Profiles of shear wave velocity vs. depth obtained through spectral analysis of interface wave testing around the perimeter of the hull in 2005 identified areas of higher velocity, stiffer sediment at the bow and starboard side, which correspond to the dense, stiff clay recovered near the bow and starboard borings. Low shear-wave velocities at the port midship and quarter of the hull correlate with the lower density, softer sediment recovered from the boring at the stern. Cross sections of the subbottom of the Memorial combine results from the sediment borings and geophysical surveys and depict a wedge of soft clay unconformably overlying the stiff clays and coral debris beneath the aft half of the USS Arizona and thickening toward the stern. The 2008 position of the hull has been documented using both tide-based and differential Global Positioning System (GPS) measuring systems. Analysis of historical and recent photographs was done to create a record of settlement from the time of sinking in 1941 to the present. By examining shadows in suitable photos, the sun azimuth, local time of day, and tide levels were determined to derive tide-adjusted and sea-level-rise-corrected elevations for structures on the hull and from these elevations to obtain settlement and tilt trends. The settlement trends, most complete for barbette 3, have two components. An early, nonlinear component ends on December 9, 1941, and represents the initial penetration and displacement of the bottom sediment by the hull. A linear, long-term trend of normal consolidation continues to the present day. Long-term settlement rates are greatest at the stern and decrease linearly to the midship, showing that the aft half of the hull is moving as an intact, rigid body. The recent rate of settlement at the stern is about 3.5 mm/year; rates at the starboard midship and forward part of the hull are less than one-third of the stern rate. The aft half of the USS Arizona hull presently tilts about 2 degrees to port, an increase of at least 1.5 degrees since the initial sinking of the ship. The results of this study identify differential settlement of the Arizona hull, due to the wedge of soft clay underlying the aft half of the hull, as the cause of the movement of the hull beneath the surface of Pearl Harbor. Calculation of sediment consolidation using lab-determined properties of the soft clay demonstrates that the observed settlements can be reproduced by projecting appropriate clay thicknesses beneath the hull. Several of the high-quality photographs analyzed for the historical settlement analysis highlight some of the limitations of this retrospective technique for determining tide-based elevations. In these cases, calculated structure elevations do not conform to the settlement trend, indicating that there can be complicating factors affecting the interpretation of the photos. Conflicting dates for events during the salvage operations were also encountered.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/sir20135096","usgsCitation":"Carkin, B.A., and Kayen, R., 2013, Settlement of the USS Arizona, Pearl Harbor, Hawaii: U.S. Geological Survey Scientific Investigations Report 2013-5096, viii, 154 p., https://doi.org/10.3133/sir20135096.","productDescription":"viii, 154 p.","numberOfPages":"166","costCenters":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":277202,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/sir20135096.gif"},{"id":277200,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/sir/2013/5096/"},{"id":277201,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/sir/2013/5096/pdf/sir2013-5096.pdf"}],"country":"United States","state":"Hawai'i","otherGeospatial":"Pearl Harbor","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -157.9702329,21.3490682 ], [ -157.9702329,21.3491682 ], [ -157.9701329,21.3491682 ], [ -157.9701329,21.3490682 ], [ -157.9702329,21.3490682 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5221b0e9e4b001cbb8a34ea3","contributors":{"authors":[{"text":"Carkin, Brad A.","contributorId":89049,"corporation":false,"usgs":true,"family":"Carkin","given":"Brad","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":483338,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kayen, Robert E. rkayen@usgs.gov","contributorId":2787,"corporation":false,"usgs":true,"family":"Kayen","given":"Robert E.","email":"rkayen@usgs.gov","affiliations":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":false,"id":483337,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

During the U.S. Department of Energy-sponsored Gas Hydrate Joint Industry Project Leg II, shear-wave velocities were measured at six wells in the Gulf of Mexico using the logging-while-drilling SonicScope acoustic tool. Because the tool measurement point was only 35 feet from the drill bit, the adverse effect of the borehole condition, which is severe for the shallow unconsolidated sediments in the Gulf of Mexico, was mini-mized and accurate shear-wave velocities of unconsolidated sediments were measured. Measured shear-wave velocities were compared with the shear-wave velocities predicted from the compressional-wave velocities using empirical formulas and the rock physics models based on the Biot-Gassmann theory, and the effectiveness of the two prediction methods was evaluated. Although the empirical equation derived from measured shear-wave data is accurate for predicting shear-wave velocities for depths greater than 500 feet in these wells, the three-phase Biot-Gassmann-theory -based theory appears to be optimum for predicting shear-wave velocities for shallow unconsolidated sediments in the Gulf of Mexico.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/sir20135141","usgsCitation":"Lee, M.W., 2013, Comparison of methods for predicting shear-wave velocities of unconsolidated shallow sediments in the Gulf of Mexico: U.S. Geological Survey Scientific Investigations Report 2013-5141, iii, 11 p., https://doi.org/10.3133/sir20135141.","productDescription":"iii, 11 p.","numberOfPages":"19","onlineOnly":"Y","costCenters":[{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true}],"links":[{"id":277191,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/sir20135141.gif"},{"id":277189,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/sir/2013/5141/"},{"id":277190,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/sir/2013/5141/pdf/SIR13-5141.pdf"}],"country":"United States","otherGeospatial":"Gulf Of Mexico","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -97.86,18.18 ], [ -97.86,30.4 ], [ -81.04,30.4 ], [ -81.04,18.18 ], [ -97.86,18.18 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5221b0e9e4b001cbb8a34ea7","contributors":{"authors":[{"text":"Lee, Myung W. mlee@usgs.gov","contributorId":779,"corporation":false,"usgs":true,"family":"Lee","given":"Myung","email":"mlee@usgs.gov","middleInitial":"W.","affiliations":[{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":483309,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Hypotheses for a Northern Hemisphere trigger, through oceanic redistributions of heat, are based in part on the abrupt onset of warming seen in East Antarctic ice cores and dated to 18,000 years ago, which is several thousand years after high-latitude Northern Hemisphere summer insolation intensity began increasing from its minimum, approximately 24,000 years ago. An alternative explanation is that local solar insolation changes cause the Southern Hemisphere to warm independently. Here we present results from a new, annually resolved ice-core record from West Antarctica that reconciles these two views. The records show that 18,000 years ago snow accumulation in West Antarctica began increasing, coincident with increasing carbon dioxide concentrations, warming in East Antarctica and cooling in the Northern Hemisphere associated with an abrupt decrease in Atlantic meridional overturning circulation. However, significant warming in West Antarctica began at least 2,000 years earlier. Circum-Antarctic sea-ice decline, driven by increasing local insolation, is the likely cause of this warming. The marine-influenced West Antarctic records suggest a more active role for the Southern Ocean in the onset of deglaciation than is inferred from ice cores in the East Antarctic interior, which are largely isolated from sea-ice changes.","language":"English","publisher":"Nature","doi":"10.1038/nature12376","usgsCitation":"Members, W.D., Fudge, T.J., Steig, E.J., Markle, B., Schoenemann, S.W., Ding, Q., Taylor, K.C., McConnell, J., Brook, E.J., Sowers, T., White, J.W., Alley, R.B., Cheng, H., Clow, G.D., Cole-Dai, J., Conway, H., Cuffey, K.M., Edwards, J.S., Edwards, R.L., Edwards, R., Fegyveresi, J., Ferris, D., Fitzpatrick, J.J., Johnson, J., Hargreaves, G., Lee, J., Maselli, O.J., Mason, W., McGwire, K.C., Mitchell, L.E., Mortensen, N.B., Neff, P., Orsi, A.J., Popp, T.J., Schauer, A.J., Severinghaus, J.P., Sigl, M., Spencer, M.K., Vaughn, B.H., Voigt, D.E., Waddington, E.D., Wang, X., and Wong, G.J., 2013, Onset of deglacial warming in West Antarctica driven by local orbital forcing: Nature, v. 500, p. 440-444, https://doi.org/10.1038/nature12376.","productDescription":"5 p.","startPage":"440","endPage":"444","numberOfPages":"5","ipdsId":"IP-043374","costCenters":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true},{"id":427,"text":"National Ice Core Laboratory","active":false,"usgs":true}],"links":[{"id":487404,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://escholarship.org/uc/item/1hm5g8hj","text":"External Repository"},{"id":278627,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":278625,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1038/nature12376"}],"otherGeospatial":"Antarctica","volume":"500","noUsgsAuthors":false,"publicationDate":"2013-08-14","publicationStatus":"PW","scienceBaseUri":"5274cd7fe4b089748f07243e","contributors":{"authors":[{"text":"Members, WAIS Divide Project","contributorId":91398,"corporation":false,"usgs":true,"family":"Members","given":"WAIS","email":"","middleInitial":"Divide Project","affiliations":[],"preferred":false,"id":485555,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Fudge, T.

When determining vulnerabilities to the U.S. supply, it is not enough to look solely at the mining source for each mineral to determine the potential impact that a supply disruption might have on the Nation’s economy. The tables that accompany this report help to illustrate the importance not only of the mining and processing of minerals but also the exporting countries and end uses. Understanding the total risks and costs of supply disruptions along the supply chain are beyond the scope of this report. However, this overview of mineral production, consumption, and trade highlights the importance of understanding what is happening at each point along the supply chain.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr20131184","usgsCitation":"Barry, J.J., Matos, G.R., and Menzie, W.D., 2013, U.S. mineral dependence—Statistical compilation of U.S. and world mineral production, consumption, and trade, 1990–2010: U.S. Geological Survey Open-File Report 2013-1184, Report: ii, 6 p.; Tables 1-85 Excel, https://doi.org/10.3133/ofr20131184.","productDescription":"Report: ii, 6 p.; Tables 1-85 Excel","numberOfPages":"12","onlineOnly":"Y","costCenters":[{"id":432,"text":"National Minerals Information Center","active":true,"usgs":true}],"links":[{"id":277167,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr20131184.gif"},{"id":277164,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2013/1184/"},{"id":277165,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2013/1184/pdf/ofr2013-1184.pdf"},{"id":277166,"type":{"id":7,"text":"Companion Files"},"url":"https://pubs.usgs.gov/of/2013/1184/excel/ofr2013-1184_table.xlsx"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5221b0eae4b001cbb8a34eaf","contributors":{"authors":[{"text":"Barry, James J. jbarry@usgs.gov","contributorId":501,"corporation":false,"usgs":true,"family":"Barry","given":"James","email":"jbarry@usgs.gov","middleInitial":"J.","affiliations":[{"id":432,"text":"National Minerals Information Center","active":true,"usgs":true}],"preferred":true,"id":483252,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Matos, Grecia R. 0000-0002-3285-3070 gmatos@usgs.gov","orcid":"https://orcid.org/0000-0002-3285-3070","contributorId":2656,"corporation":false,"usgs":true,"family":"Matos","given":"Grecia","email":"gmatos@usgs.gov","middleInitial":"R.","affiliations":[{"id":432,"text":"National Minerals Information Center","active":true,"usgs":true}],"preferred":false,"id":483253,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Menzie, W.

For the State of Colorado, elevation data are critical for natural resources conservation, agriculture and precision farming, infrastructure and construction management, flood risk management, geologic resource assessment and hazards mitigation, and other business uses. Today, high-density light detection and ranging (lidar) data are the primary sources for deriving elevation models and other datasets. Federal, State, Tribal, and local agencies work in partnership to (1) replace data that are older and of lower quality and (2) provide coverage where publicly accessible data do not exist. A joint goal of State and Federal partners is to acquire consistent, statewide coverage to support existing and emerging applications enabled by lidar data.</p>\n<p>The National Enhanced Elevation Assessment evaluated multiple elevation data acquisition options to determine the optimal data quality and data replacement cycle relative to cost to meet the identified requirements of the user community. The evaluation demonstrated that lidar acquisition at quality level 2 for the conterminous United States and quality level 5 interferometric synthetic aperture radar (ifsar) data for Alaska with a 6- to 10-year acquisition cycle provided the highest benefit/cost ratios. The 3D Elevation Program (3DEP) initiative selected an 8-year acquisition cycle for the respective quality levels. 3DEP, managed by the U.S. Geological Survey (USGS), the Office of Management and Budget Circular A&ndash;16 lead agency for terrestrial elevation data, responds to the growing need for high-quality topographic data and a wide range of other 3D representations of the Nation&rsquo;s

Marshall Loxahatchee National Wildlife Refuge, Florida in order to understand the effects of 20th century water management. We analyzed pollen assemblages from cores at marsh sites along three transects to document vegetation and infer hydroperiod and water depth both before and after human alteration of Everglades hydrology. In the northern and central part of the Refuge, late Holocene water levels were higher and hydroperiods longer than the last 100&nbsp;years. Post-1950 was a time of several different water management strategies. Pollen assemblages indicate drier conditions post-1950 in the northern and central parts of the Refuge, whereas sites in the southern Refuge are wetter and vegetation turnover is higher. Throughout the Refuge, </span><i class=\"EmphasisTypeItalic \">Sagittaria</i><span> pollen declines with the onset of water management, and may indicate a loss of greater variation in hydroperiods across years and water depths between seasons.

Semotilus\natromaculatus (Creek Chub) and Lepomis cyanellus (Green Sunfish) were collected from\nAcorn Fork a month after fracking in lieu of unavailable Blackside Dace. Tissues were histologically\nanalyzed for indicators of stress and percent of fish with lesions. Fish exposed\nto affected Acorn Fork waters showed general signs of stress and had a higher incidence of\ngill lesions than unexposed reference fish. Gill lesions observed were consistent with exposure\nto low pH and toxic concentrations of heavy metals. Gill uptake of aluminum and iron\nwas demonstrated at sites with correspondingly high concentrations of these metals. The\nabrupt and persistent changes in post-fracking water quality resulted in toxic conditions\nthat could have been deleterious to Blackside Dace health and survival.","language":"English","publisher":"Eagle Hill Institute","doi":"10.1656/058.012.s413","usgsCitation":"Papoulias, D.M., and Velasco, A.L., 2013, Histopathological analysis of fish from Acorn Fork Creek, Kentucky exposed to hydraulic fracturing fluid releases: Southeastern Naturalist, v. 12, no. sp4, p. 92-111, https://doi.org/10.1656/058.012.s413.","productDescription":"20 p.","startPage":"92","endPage":"111","ipdsId":"IP-032244","costCenters":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"links":[{"id":277151,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"12","issue":"sp4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"52205f52e4b0645fc25e8c10","contributors":{"authors":[{"text":"Papoulias, Diana M. 0000-0002-5106-2469 dpapoulias@usgs.gov","orcid":"https://orcid.org/0000-0002-5106-2469","contributorId":2726,"corporation":false,"usgs":true,"family":"Papoulias","given":"Diana","email":"dpapoulias@usgs.gov","middleInitial":"M.","affiliations":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"preferred":true,"id":483230,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Velasco, Anthony L.","contributorId":56546,"corporation":false,"usgs":true,"family":"Velasco","given":"Anthony","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":483231,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The geographical range of bighorn sheep (Ovis canadensis; BHS) overlaps with states or provinces that have contained scrapie-positive sheep or goats and areas with present epizootics of CWD in cervids. No TSEs have been documented in BHS, but the susceptibility of this species to TSEs remains unknown. Results: We acquired a library of BHS tissues and found no evidence of preexisting TSEs in these animals. The prion protein gene (Prnp) in all BHS in our library was identical to scrapie-susceptible domestic sheep (A<sup>136</sup>R <sup>154</sup>Q<sup>171</sup>). Using an in vitro prion protein conversion assay, which has been previously used to assess TSE species barriers and, in our study appears to recollect known species barriers in mice, we assessed the potential transmissibility of TSEs to BHS. As expected based upon Prnp genotype, we observed BHS prion protein conversion by classical scrapie agent and evidence for a species barrier between transmissible mink encephalopathy (TME) and BHS. Interestingly, our data suggest that the species barrier of BHS to white-tailed deer or wapiti CWD agents is likely low. We also used protein misfolding cyclic amplification to confirm that CWD, but not TME, can template prion protein misfolding in A<sup>136</sup>R <sup>154</sup>Q<sup>171</sup>genotype sheep. Conclusions: Our results indicate the in vitro conversion assay used in our study does mimic the species barrier of mice to the TSE agents that we tested. Based on Prnp genotype and results from conversion assays, BHS are likely to be susceptible to infection by classical scrapie. Despite mismatches in amino acids thought to modulate prion protein conversion, our data indicate that A136R154Q171 genotype sheep prion protein is misfolded by CWD agent, suggesting that these animals could be susceptible to CWD. Further investigation of TSE transmissibility to BHS, including animal studies, is warranted. The lack of reported TSEs in BHS may be attributable to other host factors or a lack of TSE surveillance in this species.</p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"BMC

Water management practices annually use about 86 percent of the reservoir water volume to satisfy downstream water demands. These practices might be limiting bull trout habitat and movement patterns. Bull trout are among the more thermally sensitive coldwater species in North America, and the species is listed as threatened throughout the contiguous United States under the Endangered Species Act. Biweekly water-temperature and dissolved-oxygen profiles were collected by the Bureau of Reclamation at three locations in Arrowrock to characterize habitat conditions for bull trout. Continuous streamflow and water temperature also were measured immediately upstream of the reservoir on the Middle and South Fork Boise Rivers, which influence habitat conditions in the riverine zones of the reservoir. In spring 2012, 18 bull trout ranging in total length from 306 to 630 millimeters were fitted with acoustic transmitters equipped with temperature and depth sensors. Mobile boat tracking and fixed receivers were used to detect released fish. Fish were tagged from March 28 to April 20 and were tracked through most of August. Most bull trout movements were detected in the Middle Fork Boise River arm of the reservoir. Fifteen individual fish were detected at least once after release. Water surface temperature at each fish detection location ranged from 6.0 to 16.2 degrees Celsius (°C) (mean=10.1°C), whereas bull trout body temperatures were colder, ranging from 4.4 to 11.6°C (mean=7.3°C). Bull trout were detected over deep-water habitat, ranging from 8.0 to 42.6 meters (m) (mean=18.1 m). Actual fish depths were shallower than total water depth, ranging from 0.0 to 24.5 m (mean=6.7 m). The last bull trout was detected in early June, suggesting that fish used little, if any, summertime habitat within the reservoir. Water-quality profile measurements indicated that temperature could limit bull trout use of the reservoir during warm, summer months that coincide with decreased water volume. Thermal refuge during this study appeared to be limited based on scarcity of water that was 15°C and cooler. From the first week of August through the latter part of September, little if any suitable habitat remained for bull trout, with most temperatures exceeding 15°C at all locations where water quality profiles were measured.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/sir20135158","collaboration":"Prepared in cooperation with Bureau of Reclamation","usgsCitation":"Maret, T.R., and Schultz, J.E., 2013, Bull trout (Salvelinus confluentus) movement in relation to water temperature, season, and habitat features in Arrowrock Reservoir, Idaho, 2012: U.S. Geological Survey Scientific Investigations Report 2013-5158, iv, 28 p.; Appendix A, https://doi.org/10.3133/sir20135158.","productDescription":"iv, 28 p.; Appendix A","numberOfPages":"36","additionalOnlineFiles":"Y","costCenters":[{"id":343,"text":"Idaho Water Science Center","active":true,"usgs":true}],"links":[{"id":277079,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/sir20135158.jpg"},{"id":277076,"type":{"id":3,"text":"Appendix"},"url":"https://pubs.usgs.gov/sir/2013/5158/sir20135158_appendixA.xlsx"},{"id":277074,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/sir/2013/5158/"},{"id":277075,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/sir/2013/5158/pdf/sir20135158.pdf"}],"country":"United States","state":"Idaho","otherGeospatial":"Arrowrock Reservoir","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -115.666667,43.333333 ], [ -115.666667,43.666667 ], [ -116.166667,43.666667 ], [ -116.166667,43.333333 ], [ -115.666667,43.333333 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"521f0dd8e4b0f8bf2b0760b5","contributors":{"authors":[{"text":"Maret, Terry R. trmaret@usgs.gov","contributorId":953,"corporation":false,"usgs":true,"family":"Maret","given":"Terry","email":"trmaret@usgs.gov","middleInitial":"R.","affiliations":[{"id":343,"text":"Idaho Water Science Center","active":true,"usgs":true}],"preferred":true,"id":483167,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Schultz, Justin E.","contributorId":86253,"corporation":false,"usgs":true,"family":"Schultz","given":"Justin","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":483168,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

We found that owl presence was closely tied to habitat (red fir (Abies magnified A. Murray) and the abundance of meadows), prey, and snags across the landscape. We also found that indicators of human recreational activities negatively influenced owl distribution and habitat use. Great gray owls appear to prefer mid-elevation red fir forest with meadows that are drier and more productive in terms of small mammal populations. That these areas also have the highest human activity presents a paradox, both for individual owls and for the future conservation and management of this California endangered species. The extent to which human recreation in natural areas affects animal behavior, species distribution, and productivity is a growing issue in natural area management.

Groundwater withdrawals have increased while water levels have declined since monitoring was initiated. Herein, aquifers in the Sparta Sand and Memphis Sand will be referred to as the Sparta-Memphis aquifer throughout Arkansas. During the spring of 2009, 324 water levels were measured in wells completed in the Sparta-Memphis aquifer and used to produce a regional potentiometric-surface map. During the summer of 2009, 64 water-quality samples were collected and measured for specific conductance, temperature, and pH from wells completed in the Sparta-Memphis aquifer.\n\nThe regional direction of groundwater flow in the Sparta-Memphis aquifer is generally to the south-southeast in the northern half of Arkansas and to the east and south in the southern half of Arkansas, away from the outcrop area except where affected by large groundwater withdrawals. The highest and lowest water-level altitudes measured in the Sparta-Memphis aquifer were 325 feet above and 157 feet below National Geodetic Vertical Datum of 1929, respectively.\n\nEight depressions (generally represented by closed contours) are located in the following counties: Bradley; Ashley; Calhoun; Cleveland; Columbia; Arkansas, Jefferson, Lincoln, and Prairie; Cross and Poinsett; and Union. Two large depressions shown on the 2009 potentiometric-surface map, centered in Jefferson and Union Counties, are the result of large withdrawals for industrial, irrigation, or public supply. The depression centered in Jefferson County deepened and expanded in recent years into Arkansas and Prairie Counties. The area enclosed within the 40-foot contour on the 2009 potentiometric-surface map has expanded south to the Drew County line and moved west from the intersection of Arkansas, Jefferson, and Lincoln Counties when compared with the 2007 potentiometric-surface map. To the north, east, and west, the 40-foot contour is comparable to the 2007 potentiometric-surface map. The lowest water-level altitude measurement during 2009 in the center of the depression in Union County represents a rise of 42 feet since 2003. The area enclosed by the lowest altitude contour, 140 feet below National Geodetic Vertical Datum of 1929, on the 2009 potentiometric-surface map is about half the area on the 2007 potentiometric-surface map. In the depression in western Poinsett and Cross Counties, the 140-foot contour extended north to the Poinsett-Craighead County line and south across Cross County about two-thirds of the distance to the St. Francis County line.\n\nA water-level difference map was constructed using water-level measurements made during 2005 and 2009 from 309 wells. The difference in water level between 2005 and 2009 ranged from -74.6 to 60.2 feet. Areas with a general rise in water levels occur in central Columbia County, southern Jefferson County, and most of Union County. In the area around west-central Union County, water levels rose as much as 60.2 feet with water levels in 18 wells rising 20 feet or more, representing an average annual rise of 5 feet or more. Water levels generally declined throughout most of the rest of Arkansas.\n\nHydrographs were constructed using a minimum of 25 years of water-level measurements at each of 206 wells. During the period 1985–2009, mean annual water levels rose in Calhoun, Columbia, Lafayette, and Union Counties, about 1.3 feet per year (ft/yr), 0.2 ft/yr, 0.1 ft/yr, and 0.6 ft/yr, respectively. Mean annual water-level declines between 0.0 and 2.3 ft/yr occurred in all other counties. In western Arkansas County, water-level altitudes in a continuously monitored well declined 60 feet during the irrigation season (April to September).\n\nSpecific conductance ranged from 43 microsiemens per centimeter at 25 degrees Celsius (μS/cm) in Ouachita County to 1,230 μS/cm in Phillips County. The mean specific conductance was 392 μS/cm. Although there is a regional increase in specific conductance to the east and south, specific conductance values greater than 700 μS/cm occurred in samples from wells in Arkansas, Ashley, Monroe, Phillips, and Union Counties.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/sir20135100","collaboration":"Prepared in cooperation with the Arkansas Natural Resources Commission and the Arkansas Geological Survey","usgsCitation":"Schrader, T., 2013, Water levels and water quality in the Sparta-Memphis aquifer (middle Claiborne aquifer) in Arkansas, spring-summer 2009: U.S. Geological Survey Scientific Investigations Report 2013-5100, Report: iv, 53 p.; 2 plates: 24 x 27 inches, https://doi.org/10.3133/sir20135100.","productDescription":"Report: iv, 53 p.; 2 plates: 24 x 27 inches","temporalStart":"2009-03-01","temporalEnd":"2009-09-30","costCenters":[{"id":129,"text":"Arkansas Water Science Center","active":true,"usgs":true}],"links":[{"id":277060,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/sir20135100.PNG"},{"id":277056,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/sir/2013/5100/"},{"id":277055,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/sir/2013/5100/pdf/sir2013-5100.pdf"},{"id":277057,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/sir/2013/5100/pdf/sir2013-5100_pl1.pdf"},{"id":277058,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/sir/2013/5100/pdf/sir2013-5100_pl2.pdf"}],"country":"United States","state":"Arkansas","otherGeospatial":"Sparta-memphis Aquifer","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -94.1125,33.0041 ], [ -94.1125,36.4997 ], [ -89.6448,36.4997 ], [ -89.6448,33.0041 ], [ -94.1125,33.0041 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"52a6408fe4b0a6d6958827a7","contributors":{"authors":[{"text":"Schrader, T.P.","contributorId":56300,"corporation":false,"usgs":true,"family":"Schrader","given":"T.P.","email":"","affiliations":[],"preferred":false,"id":483141,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The first storm produced a total of approximately 16 inches of precipitation over an 8-day period, and the following storms produced as much as 12 inches of precipitation over a 2-day period. Moderate to major flooding occurred quickly along many streams within Arkansas and Missouri (including the Black, Cache, Illinois, St. Francis, and White Rivers) at levels that had not been seen since the historic 1927 floods. The 2011 flood claimed an estimated 21 lives in Arkansas and Missouri, and damage caused by the flooding resulted in a Federal Disaster Declaration for 59 Arkansas counties that received Federal or State assistance. To further the goal of documenting and understanding floods, the U.S. Geological Survey, in cooperation with the Federal Emergency Management Agency, the U.S. Army Corps of Engineers–Little Rock and Memphis Districts, and Arkansas Natural Resources Commission, conducted a study to summarize meteorological and hydrological conditions before the flood; computed flood-peak magnitudes for 39 streamgages; estimated annual exceedance probabilities for 37 of those streamgages; determined the joint probabilities for 11 streamgages paired to the Mississippi River at Helena, Arkansas, which refers to the probability that locations on two paired streams simultaneously experience floods of a magnitude greater than or equal to a given annual exceedance probability; collected high-water marks; constructed flood-peak inundation maps showing maximum flood extent and water depths; and summarized flood damages and effects.\n\nFor the period of record used in this report, peak-of-record stage occurred at 24 of the 39 streamgages, and peak-of-record streamflow occurred at 13 of the 30 streamgages where streamflow was determined. Annual exceedance probabilities were estimated to be less than 0.5 percent at three streamgages. The joint probability values for streamgages paired with the Mississippi River at Helena, Ark., streamgage indicate a low probability of concurrent flooding with the paired streamgages. The inundation maps show the flood-peak extent and water depth of flooding for two stream reaches on the White River and two on the Black River; the vicinities of the communities of Holly Grove and Cotton Plant, Ark.; a reach of the White River that includes the crossing of Interstate 40 north of De Valls Bluff, Ark.; and the Tailwaters of Beaver Dam near Eureka Springs, Ark., Table Rock Dam near Branson, Mo., and Bull Shoals Dam near Flippin, Ark. The data and inundation maps can be used for flood response, recovery, and planning efforts by Federal, State, and local agencies.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/sir20135148","collaboration":"Prepared in cooperation with the Federal Emergency Management Agency, the U.S. Army Corps of Engineers--Little Rock and Memphis Districts, and the Arkansas Natural Resources Commission","usgsCitation":"Westerman, D.A., Merriman, K., De Lanois, J.L., and Berenbrock, C., 2013, Analysis and inundation mapping of the April-May 2011 flood at selected locations in northern and eastern Arkansas and southern Missouri: U.S. Geological Survey Scientific Investigations Report 2013-5148, Report: vii, 44 p.; Downloads Directory, https://doi.org/10.3133/sir20135148.","productDescription":"Report: vii, 44 p.; Downloads Directory","onlineOnly":"Y","temporalStart":"2011-04-19","temporalEnd":"2011-05-03","costCenters":[{"id":129,"text":"Arkansas Water Science Center","active":true,"usgs":true}],"links":[{"id":277054,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/sir20135148.PNG"},{"id":277051,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/sir/2013/5148/"},{"id":277052,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/sir/2013/5148/pdf/sir2013-5148.pdf"},{"id":277053,"type":{"id":7,"text":"Companion Files"},"url":"https://pubs.usgs.gov/sir/2013/5148/Downloads/"}],"country":"United States","state":"Arkansas;Missouri","otherGeospatial":"Arkansas River Basin;St. Francis River Basin;White River Basin","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -94.6179,34.7823 ], [ -94.6179,37.2905 ], [ -89.6448,37.2905 ], [ -89.6448,34.7823 ], [ -94.6179,34.7823 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"521dcbc6e4b051c878dc355d","contributors":{"authors":[{"text":"Westerman, Drew A. 0000-0002-8522-776X dawester@usgs.gov","orcid":"https://orcid.org/0000-0002-8522-776X","contributorId":4526,"corporation":false,"usgs":true,"family":"Westerman","given":"Drew","email":"dawester@usgs.gov","middleInitial":"A.","affiliations":[{"id":129,"text":"Arkansas Water Science Center","active":true,"usgs":true},{"id":24708,"text":"Lower Mississippi-Gulf Water Science Center","active":true,"usgs":true}],"preferred":true,"id":483137,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Merriman, Katherine R.","contributorId":34418,"corporation":false,"usgs":true,"family":"Merriman","given":"Katherine R.","affiliations":[],"preferred":false,"id":483140,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"De Lanois, Jeanne L. jdelanoi@usgs.gov","contributorId":4672,"corporation":false,"usgs":true,"family":"De Lanois","given":"Jeanne","email":"jdelanoi@usgs.gov","middleInitial":"L.","affiliations":[],"preferred":true,"id":483138,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Berenbrock, Charles","contributorId":30598,"corporation":false,"usgs":true,"family":"Berenbrock","given":"Charles","email":"","affiliations":[],"preferred":false,"id":483139,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Through a combination of historical borehole and cross-section data and digital terrain modeling, the Samti, Nooraba-Khasar-Anjir, and Kocha River placer deposits were reassessed. Resource estimates were calculated to be 20,927 kilograms (kg) for Samti, 7,626 kg for Nooraba-Khasar-Anjir, 160 kg for the mouth of the Kocha, 1,047 kg for the lower Kocha, 113 kg for the middle Kocha, and 168 kg for the upper Kocha. Previous resource estimates conducted by the Soviets for the Samti and Nooraba-Khasar-Anjir deposits estimated 30,062 kg and 802 kg of gold, respectively. This difference between the new estimates and previous estimates results from the higher resolution geomorphic model and the interpretation of areas outside of the initial work zone studied by Soviet and Afghan geologists.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr20131180","collaboration":"Prepared in cooperation with the Afghan Geological Survey under the auspices of the U.S. Department of Defense Task Force for Business and Stability Operations; USGS Afghanistan Project Product No. 184","usgsCitation":"Chirico, P., Malpeli, K., and Moran, T., 2013, Reconnaissance investigation of the alluvial gold deposits in the North Takhar Area of Interest, Takhar Province, Afghanistan: U.S. Geological Survey Open-File Report 2013-1180, iv, 14 p.; 6 Figures: 35 x 31 inches, https://doi.org/10.3133/ofr20131180.","productDescription":"iv, 14 p.; 6 Figures: 35 x 31 inches","onlineOnly":"Y","additionalOnlineFiles":"Y","costCenters":[{"id":243,"text":"Eastern Geology and Paleoclimate Science Center","active":true,"usgs":true}],"links":[{"id":277044,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr20131180.gif"},{"id":277037,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2013/1180/pdf/of2013-1180.pdf"},{"id":277038,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/2013/1180/pdf/of2013-1180_figure1.pdf"},{"id":277039,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/2013/1180/pdf/of2013-1180_figure2.pdf"},{"id":277040,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/2013/1180/pdf/of2013-1180_figure3.pdf"},{"id":277041,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/2013/1180/pdf/of2013-1180_figure4.pdf"},{"id":277042,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/2013/1180/pdf/of2013-1180_figure5.pdf"},{"id":277043,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/2013/1180/pdf/of2013-1180_figure6.pdf"},{"id":277036,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2013/1180/"}],"country":"Afghanistan","state":"Takhar Province","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 74.89,29.38 ], [ 74.89,38.49 ], [ 60.52,38.49 ], [ 60.52,29.38 ], [ 74.89,29.38 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"52a64065e4b0a6d695882609","contributors":{"authors":[{"text":"Chirico, Peter G.","contributorId":27086,"corporation":false,"usgs":true,"family":"Chirico","given":"Peter G.","affiliations":[],"preferred":false,"id":483115,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Malpeli, Katherine C.","contributorId":55106,"corporation":false,"usgs":true,"family":"Malpeli","given":"Katherine C.","affiliations":[],"preferred":false,"id":483116,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Moran, Thomas W.","contributorId":102999,"corporation":false,"usgs":true,"family":"Moran","given":"Thomas W.","affiliations":[],"preferred":false,"id":483117,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The purpose of this study was to integrate new mapping techniques with previously collected concentration and borehole sampling data and geomorphologic interpretations to reassess the placer gold deposits in the Zarkashan AOI. A methodology combining the collection and analysis of historical sampling data, digital database development, hydrologic analysis, and geomorphic modeling was used. The analysis led to the reinterpretation of four gold-bearing seams along the Zarkashan River, and the calculation of an estimated gold reserve of approximately 3,000 kilograms (kg). This estimate is approximately 1,500 kg greater than the Soviet estimate. The result differs in large part due to the reinterpretation of the seams based on a much lower cutoff grade of 100 mg/m<sup>3</sup>. Because cutoff grade is dependent in part on the price of gold, the sevenfold increase in the price of gold since the undertaking of the Soviet investigation warranted our re-evaluation of their 500 mg/m<sup>3</sup> cutoff grade.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr20131179","collaboration":"Prepared in cooperation with the Afghan Geological Survey under the auspices of the U.S. Department of Defense Task Force for Business and Stability Operations; USGS Afghanistan Project Product No. 185","usgsCitation":"Malpeli, K., Chirico, P., and McLoughlin, I.H., 2013, Reconnaissance investigation of the placer gold deposits in the Zarkashan Area of Interest, Ghazni Province, Afghanistan: U.S. Geological Survey Open-File Report 2013-1179, iv, 12 p.; 4 Figures: 40 x 26 inches, https://doi.org/10.3133/ofr20131179.","productDescription":"iv, 12 p.; 4 Figures: 40 x 26 inches","onlineOnly":"Y","additionalOnlineFiles":"Y","costCenters":[{"id":243,"text":"Eastern Geology and Paleoclimate Science Center","active":true,"usgs":true}],"links":[{"id":277034,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr20131179.gif"},{"id":277029,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2013/1179/"},{"id":277028,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2013/1179/pdf/of2013-1179.pdf"},{"id":277030,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/2013/1179/pdf/of2013-1179_figure1.pdf"},{"id":277031,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/2013/1179/pdf/of2013-1179_figure2.pdf"},{"id":277032,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/2013/1179/pdf/of2013-1179_figure3.pdf"},{"id":277033,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/2013/1179/pdf/of2013-1179_figure4.pdf"}],"country":"Afghanistan","otherGeospatial":"Ghazni Province","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 67.0,32.583333 ], [ 67.0,33.333333 ], [ 68.5,33.333333 ], [ 68.5,32.583333 ], [ 67.0,32.583333 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"52a64066e4b0a6d69588260d","contributors":{"authors":[{"text":"Malpeli, Katherine C.","contributorId":55106,"corporation":false,"usgs":true,"family":"Malpeli","given":"Katherine C.","affiliations":[],"preferred":false,"id":483113,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Chirico, Peter G.","contributorId":27086,"corporation":false,"usgs":true,"family":"Chirico","given":"Peter G.","affiliations":[],"preferred":false,"id":483112,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"McLoughlin, Isabel H.","contributorId":63295,"corporation":false,"usgs":true,"family":"McLoughlin","given":"Isabel","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":483114,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Extreme storms can cause dramatic changes to our shorelines in a matter of hours, while sea-level rise can profoundly alter coastal environments over decades. These changes can have a devastating impact on coastal communities, such as the loss of homes built on retreating sea cliffs or protective dunes eroded by storm waves. Sometimes, however, the changes can be positive, such as new habitat created by storm deposits. The U.S. Geological Survey (USGS) is meeting the need for scientific understanding of how our coasts respond to different hazards with continued assessments of current and future changes along U.S. coastlines. Through the National Assessment of Coastal Change Hazards (NACCH), the USGS carries out the unique task of quantifying coastal change hazards along open-ocean coasts in the United States and its territories. Residents of coastal communities, emergency managers, and other stakeholders can use science-based data, tools, models, and other products to improve planning and enhance resilience.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/fs20133077","usgsCitation":"Stockdon, H.F., Hapke, C.J., Thieler, E.R., and

Field surveys of the beach and dunes collected just prior to and after landfall were used to quantify change in several focus areas. In order to quantify morphologic change along the length of the island, pre-storm (May 2012) and post-storm (November 2012) lidar and aerial photography were used to assess changes to the shoreline and beach, and to measure volumetric changes. The extent and thicknesses of overwash deposits were mapped in the field, and measurements were used to determine volume, distribution, and characteristics of the deposits.\n\nThe beaches and dunes on Fire Island were severely eroded during Hurricane Sandy, and the island breached in three locations on the eastern segment of the island. Landward shift of the upper portion of the beach averaged 19.7 meters (m) but varied substantially along the coast. Shoreline change was also highly variable, but the shoreline prograded during the storm by an average of 11.4 m, due to the deposition of material eroded from the upper beach and dunes onto the lower portion of the beach. The beaches and dunes lost 54.4 percent of their pre-storm volume, and the dunes experienced overwash along 46.6 percent of the island. The inland overwash deposits account for 14 percent of the volume lost from the beaches and dunes, indicating that the majority of material was moved offshore.\n\nIn the winter months following Hurricane Sandy, seven storm events with significant wave heights greater than four m were recorded at a wave buoy 30 nautical miles south of Fire Island. Monthly shoreline and profile surveys indicate that the beach continued to erode dramatically. The shoreline, which exhibited a progradational trend immediately after Sandy, eroded an average of 21.4 m between November 2012 and mid-March 2013, with a maximum landward shift of nearly 60 m. By March 2013 the elevation of the beach in the majority of the surveyed profiles was lowered below the mean high water level (0.46 m), and the beach lost an additional 18.9 percent of its remaining volume. In the final time period of the field surveys (March to April 2013), the beach began to show signs of rapid recovery, and in 90 percent of the profiles, the volume of the beach in April 2013 was similar to the volume measured immediately after Hurricane Sandy.\n\nOverall, Hurricane Sandy profoundly impacted the morphology of Fire Island and resulted in an extremely low elevation, low relief configuration that has left the barrier island vulnerable to future storms. The coastal system subsequently began to show signs of recovery, and although the beach is likely to experience continued recovery in the form of volume gains, the dunes will take years to rebuild. Events such as Sandy result in a coastal environment that is a more vulnerable to future storm impacts, but they are an important natural process of barrier islands that allow these systems to evolve in response to sea-level rise.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr20131231","usgsCitation":"Hapke, C.J., Brenner, O., Henderson, R., and Reynolds, B., 2013, Coastal change from Hurricane Sandy and the 2012-13 winter storm season: Fire Island, New York: U.S. Geological Survey Open-File Report 2013-1231, vi, 37 p., https://doi.org/10.3133/ofr20131231.","productDescription":"vi, 37 p.","numberOfPages":"43","onlineOnly":"Y","additionalOnlineFiles":"N","temporalStart":"2012-05-01","temporalEnd":"2012-11-30","costCenters":[{"id":574,"text":"St. Petersburg Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":277023,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr20131231.gif"},{"id":277022,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2013/1231/"},{"id":277027,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2013/1231/pdf/ofr2013-1231.pdf"}],"country":"United States","state":"New York","otherGeospatial":"Fire Island","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -73.306874,40.62042 ], [ -73.306874,40.779037 ], [ -72.727963,40.779037 ], [ -72.727963,40.62042 ], [ -73.306874,40.62042 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"52722a8be4b0ce70249c9816","contributors":{"authors":[{"text":"Hapke, Cheryl J. 0000-0002-2753-4075 chapke@usgs.gov","orcid":"https://orcid.org/0000-0002-2753-4075","contributorId":2981,"corporation":false,"usgs":true,"family":"Hapke","given":"Cheryl","email":"chapke@usgs.gov","middleInitial":"J.","affiliations":[{"id":6676,"text":"USGS (retired)","active":true,"usgs":false}],"preferred":true,"id":483011,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Brenner, Owen","contributorId":7987,"corporation":false,"usgs":true,"family":"Brenner","given":"Owen","affiliations":[],"preferred":false,"id":483013,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Henderson, Rachel E. 0000-0001-5810-7941 rhehre@usgs.gov","orcid":"https://orcid.org/0000-0001-5810-7941","contributorId":4934,"corporation":false,"usgs":true,"family":"Henderson","given":"Rachel E.","email":"rhehre@usgs.gov","affiliations":[{"id":574,"text":"St. Petersburg Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":false,"id":483012,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Reynolds, B.J.","contributorId":47874,"corporation":false,"usgs":true,"family":"Reynolds","given":"B.J.","email":"","affiliations":[],"preferred":false,"id":483014,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}
