Conservation funding has not often been allocated in accordance with explicit biological endpoints, and the gap between conservation design (the identification of conservation priority areas) and delivery needs to be bridged to better meet conservation goals for multiple species and landscapes. We introduce a regional prioritization scheme for North American Wetlands Conservation Act funding which explicitly addresses Midwest regional goals for wetland-dependent birds. We developed decision-support maps to guide conservation of breeding and non-breeding wetland bird habitat. This exercise suggested ~55% of the Midwest consists of potential wetland bird habitat, and areas suited for maintenance (protection) were distinguished from those most suited to restoration. Areas with greater maintenance focus were identified for central Minnesota, southeastern Wisconsin, the Upper Mississippi and Illinois rivers, and the shore of western Lake Erie and Saginaw Bay. The shores of Lakes Michigan and Superior accommodated fewer waterbird species overall, but were also important for wetland bird habitat maintenance. Abundant areas suited for wetland restoration occurred in agricultural regions of central Illinois, western Iowa, and northern Indiana and Ohio. Use of this prioritization scheme can increase effectiveness, efficiency, transparency, and credibility to land and water conservation efforts for wetland birds in the Midwestern United States.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Conservation Planning","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"University of Florida","publisherLocation":"Gainesville, FL","usgsCitation":"Thogmartin, W., Potter, B., and Soulliere, G., 2011, Bridging the conservation design and delivery gap for wetland bird habitat maintenance and restoration in the Midwestern United States: Journal of Conservation Planning, v. 7, p. 1-12.","productDescription":"12 p.","startPage":"1","endPage":"12","costCenters":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"links":[{"id":204544,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":94373,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://www.journalconsplanning.org/2011/index.html","linkFileType":{"id":5,"text":"html"}}],"country":"United States","otherGeospatial":"Midwest","volume":"7","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0ae4b07f02db5fb3ac","contributors":{"authors":[{"text":"Thogmartin, W.E. 0000-0002-2384-4279","orcid":"https://orcid.org/0000-0002-2384-4279","contributorId":26392,"corporation":false,"usgs":true,"family":"Thogmartin","given":"W.E.","affiliations":[],"preferred":false,"id":353008,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Potter, B.","contributorId":10147,"corporation":false,"usgs":true,"family":"Potter","given":"B.","email":"","affiliations":[],"preferred":false,"id":353007,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Soulliere, G.","contributorId":31107,"corporation":false,"usgs":true,"family":"Soulliere","given":"G.","email":"","affiliations":[],"preferred":false,"id":353009,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Despite a heightened global concern for native mussels, fundamental research on mussel ecology in large rivers is lacking. These gaps in knowledge about where mussels occur, and why, are limiting habitat restoration activities.  2. Large-scale systematic surveys for native mussels in three reaches of the Upper Mississippi River documented mussel communities composed of 16&ndash;23 species and ranging from 2.9&ndash;4.5 live mussels m<sup>-2</sup> that were actively recruiting new cohorts into their populations (87&ndash;100% of the species were found as juveniles 5 years old). Estimates of mean tissue biomass and production in these reaches ranged from 2.1&ndash;3.1 g C m<sup>-2</sup> and 0.4&ndash;0.6 g C m<sup>-2</sup>year<sup>-1</sup>, respectively.  3. Mussels filtered a significant amount of water (range, 0.05&ndash;0.07 m<sup>3</sup>m<sup>-2</sup>d<sup>-1</sup>) over a 480 km reach of the Upper Mississippi River &mdash; amounting to a filtration rate of 53.1 million m<sup>3</sup>day<sup>-1</sup>. The filtration rate of mussels as a percentage of river discharge ranged from 0.5&ndash;1.4% at high flows (5% exceedance), from 1.5&ndash;4.4% at moderate flows (50% exceedance) and from 4.4&ndash;12.2% during low flows (95% exceedance).  4. Collectively, these data suggest that native mussels play an integral role in this ecosystem by sequestering suspended materials that can be used by other benthic organisms.","language":"English","publisher":"Wiley","publisherLocation":"Hoboken, NJ","doi":"10.1002/aqc.1170","usgsCitation":"Newton, T., Zigler, S.J., Rogala, J.T., Gray, B.R., and Davis, M., 2011,

Although both processes operate over similar spatial and temporal scales and are likely strongly coupled in many dryland systems, aeolian and fluvial processes have traditionally been studied separately, making it difficult to assess their relative importance in drylands, as well as their potential for synergistic interaction. Land degradation by accelerated wind and water erosion is a major problem throughout the world's drylands, and although recent studies suggest that these processes likely interact across broad spatial and temporal scales to amplify the transport of soil resources from and within drylands, many researchers and land managers continue to view them as separate and unrelated processes. Here, we illustrate how aeolian and fluvial sediment transport is coupled at multiple spatial and temporal scales and highlight the need for these interrelated processes to be studied from a more integrated perspective that crosses traditional disciplinary boundaries.

Coronae in particular have magmatic, tectonic, and topographic signatures that indicate complex evolutionary histories.  Previously, the geology of the map region has been described either in general or narrowly focused investigations. Based on Venera radar mapping, a 1:15,000,000-scale geologic map of part of the northern hemisphere of Venus included the V&ndash;6 map region and identified larger features such as tesserae, smooth and hummocky plains materials, ridge belts, coronae, volcanoes, and impact craters but proposed little relative-age information. Global-scale mapping from Magellan data identified similar features and also determined their mean global ages with crater counts. However, the density of craters on Venus is too low for meaningful relative-age determinations at local to regional scales. Several of the coronae in the map area have been described using Venera data (Stofan and Head, 1990), while Crumpler and others (1992) compiled detailed identification and description of volcanic and tectonic features from Magellan data.  The main purpose of this map is to reconstruct the geologic history of the Metis Mons quadrangle at a level of detail commensurate with a scale of 1:5,000,000 using Magellan data. We interpret four partly overlapping stages of geologic activity, which collectively resulted in the formation of tesserae, coronae (oriented along structure belts), plains materials of varying ages, and four large volcanic constructs. Scattered impact craters, small shields and pancake-shaped domes, and isolated flows superpose the tectonically deformed materials and appear to be the most youthful materials in the map region.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/sim3158","collaboration":"Prepared for the National Aeronautics and Space Administration","usgsCitation":"Dohm, J.M., Tanaka, K.L., and Skinner, J., 2011, Geologic map of the Metis Mons quadrangle (V&ndash;6), Venus: U.S. Geological Survey Scientific Investigations Map 3158, Pamphlet: ii, 12 p., Tables; Map: 47.24 x 36.42 inches; GIS Database Downloads: Readme, Metadata, Data, https://doi.org/10.3133/sim3158.","productDescription":"Pamphlet: ii, 12 p., Tables; Map: 47.24 x 36.42 inches; GIS Database Downloads: Readme, Metadata, Data","additionalOnlineFiles":"Y","costCenters":[{"id":131,"text":"Astrogeology Science Center","active":true,"usgs":true}],"links":[{"id":116562,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/sim_3158.gif"},{"id":414269,"rank":3,"type":{"id":2,"text":"Additional Report Piece"},"url":"https://doi.org/10.5066/P928WA0S","text":"Interactive map","linkHelpText":"- Geologic Map of the Metis Mons Quadrangle (V–6), Venus, 1:5M.

The reproductive health and seasonal variation of the reproductive end points of razorback sucker populations are currently unknown. Using nonlethal methods, we characterized the plasma hormonal fluctuations of reproductively mature female and male razorback suckers over a 12-month period in a hatchery by measuring their vitellogenin (VTG) and three sex hormones: 17&beta;-estradiol (E2), testosterone (T), and 11-ketotestosterone (KT). Fish were identified as reproductive or nonreproductive based on their body weight, VTG, and sex hormone profiles. In reproductive females, the E2 concentration increased in the fall and winter, and increases in T and VTG concentrations were generally associated with the spawning period. Mean T concentrations were consistently greater in reproductive females than in nonreproductive females, but this pattern was even more pronounced during the spawning period (spring). Consistently low T concentrations (<3 ng/mL) in adult females during the spawning period may indicate reproductive impairment. In reproductive males, spring increases in KT and T concentrations were associated with spawning; concentrations of E2 (<0.48 ng/mL) and VTG (<0.001 mg/mL) were low in males throughout the study. In addition, the E2 : KT ratio and T were the best metrics by which to distinguish female from male adult razorback suckers throughout the year. These metrics of reproductive health and condition may be particularly important to recovery efforts of razorback suckers given that the few remaining wild populations are located in a river where water quality and quantity issues are well documented. In addition to the size, age, and recruitment information currently considered in the recovery goals of this endangered species, reproductive end points could be included as recovery metrics with which to monitor seasonal trends and determine whether repatriated populations are cycling naturally.","language":"English","publisher":"Taylor and Francis","doi":"10.1080/02755947.2011.591231","usgsCitation":"Hinck, J.E., Papoulias, D.M., Annis, M., Tillitt, D.E., Marr, C., Denslow, N., Kroll, K.J., and Nachtmann, J., 2011, Characterization of plasma vitellogenin and sex hormone concentrations during the annual reproductive cycle of the endangered razorback sucker: North American Journal of Fisheries Management, v. 31, no. 5, p. 765-781, https://doi.org/10.1080/02755947.2011.591231.","productDescription":"17 p.","startPage":"765","endPage":"781","numberOfPages":"17","costCenters":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true},{"id":34983,"text":"Contaminant Biology Program","active":true,"usgs":true}],"links":[{"id":204445,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"31","issue":"5","noUsgsAuthors":false,"publicationDate":"2011-09-20","publicationStatus":"PW","scienceBaseUri":"4f4e49e2e4b07f02db5e4d52","contributors":{"authors":[{"text":"Hinck, Jo Ellen 0000-0002-4912-5766","orcid":"https://orcid.org/0000-0002-4912-5766","contributorId":38507,"corporation":false,"usgs":true,"family":"Hinck","given":"Jo","email":"","middleInitial":"Ellen","affiliations":[],"preferred":false,"id":352823,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"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":352821,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Annis, Mandy L.","contributorId":41575,"corporation":false,"usgs":true,"family":"Annis","given":"Mandy L.","affiliations":[],"preferred":false,"id":352824,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Tillitt, Donald E. 0000-0002-8278-3955 dtillitt@usgs.gov","orcid":"https://orcid.org/0000-0002-8278-3955","contributorId":1875,"corporation":false,"usgs":true,"family":"Tillitt","given":"Donald","email":"dtillitt@usgs.gov","middleInitial":"E.","affiliations":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"preferred":true,"id":352820,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Marr, Carrie","contributorId":58766,"corporation":false,"usgs":true,"family":"Marr","given":"Carrie","email":"","affiliations":[],"preferred":false,"id":352825,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Denslow, Nancy D.","contributorId":72831,"corporation":false,"usgs":true,"family":"Denslow","given":"Nancy D.","affiliations":[],"preferred":false,"id":352826,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Kroll, Kevin J.","contributorId":82051,"corporation":false,"usgs":true,"family":"Kroll","given":"Kevin","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":352827,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Nachtmann, Jason","contributorId":37055,"corporation":false,"usgs":true,"family":"Nachtmann","given":"Jason","email":"","affiliations":[],"preferred":false,"id":352822,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

We compared two statistical and three theoretical habitat modeling approaches representing those currently being used for avian conservation planning at landscape and regional scales: hierarchical spatial count (HSC), classification and regression tree (CRT), habitat suitability index (HSI), forest structure database (FS), and habitat association database (HA). We focused our comparison on models for five priority forest-breeding species in the Central Hardwoods Bird Conservation Region: Acadian Flycatcher, Cerulean Warbler, Prairie Warbler, Red-headed Woodpecker, and Worm-eating Warbler. Lacking complete knowledge on the distribution and abundance of each species with which we could illuminate differences between approaches and provide strong grounds for recommending one approach over another, we used two approaches to compare models: rank correlations among model outputs and comparison of spatial correspondence. In general, rank correlations were significantly positive among models for each species, indicating general agreement among the models. Worm-eating Warblers had the highest pairwise correlations, all of which were significant (<i>P</i> , 0.05). Red-headed Woodpeckers had the lowest agreement among models, suggesting greater uncertainty in the relative conservation value of areas within the region. We assessed model uncertainty by mapping the spatial congruence in priorities (i.e., top ranks) resulting from each model for each species and calculating the coefficient of variation across model ranks for each location. This allowed identification of areas more likely to be good targets of conservation effort for a species, those areas that were least likely, and those in between where uncertainty is higher and thus conservation action incorporates more risk. Based on our results, models developed independently for the same purpose (conservation planning for a particular species in a particular geography) yield different answers and thus different conservation strategies. We assert that using only one habitat model (even if validated) as the foundation of a conservation plan is risky. Using multiple models (i.e., ensemble prediction) can reduce uncertainty and increase efficacy of conservation action when models corroborate one another and increase understanding of the system when they do not.","language":"English","publisher":"Ecological Society of America","publisherLocation":"Ithaca, NY","doi":"10.1890/10-1047.1","usgsCitation":"Jones-Farrand, D., Fearer, T.M., Thogmartin, W.E., Thompson, F.R., Nelson, M.D., and Tirpak, J.M., 2011, Comparison of statistical and theoretical habitat models for conservation planning: The benefit of ensemble prediction: Ecological Applications, v. 21, no. 6, p. 2269-2282, https://doi.org/10.1890/10-1047.1.","productDescription":"14 p.","startPage":"2269","endPage":"2282","costCenters":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"links":[{"id":204436,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"21","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b23e4b07f02db6adff6","contributors":{"authors":[{"text":"Jones-Farrand, D.

Temporal trends were identified with generalized additive mixed effects models and mixed effects models to account for the potential lack of independence among observations from the same loon or same lake. Trend analyses indicated that Hg concentrations in the blood of Wisconsin loons declined over the period 1992–2000, and increased during 2002–2010, but not to the level observed in the early 1990s. The best fitting linear mixed effects model included separate trends for the two time periods.

Recently, the US Fish and Wildlife Service listed Painted Buntings as a focal species. Surveys for this focal species for the next 10 yrs (BBS, 1997&ndash;2007), however, are too low (<1 bird per 50 stops) for determining trend estimates. Also, to monitor densities adequately, surveys should account for incomplete detections. I surveyed singing Painted Buntings from 13 May to 26 June 2003 at 582 point counts (50 randomly selected transects) within blocks (64 &#215; 64 km) in coastal and river areas from Florida to North Carolina. I compared densities of Painted Buntings for major habitats. Painted Buntings were detected at 33.5% of points surveyed for 5 min. Densities varied from 9 singing males per km<sup>2</sup> in young pine plantations to 42 per km<sup>2</sup> in maritime shrub. Effective detection radii for habitats varied from 64 to 90 m and were slightly higher in developed than in undeveloped habitats. Distance sampling is recommended to determine densities of Painted Buntings; however, large sample sizes (70&ndash;100 detections/habitat type) are required to monitor Painted Bunting densities in most habitats in the Atlantic coastal region of the southeastern United States. Special attention should be given to maritime shrub habitats, which may be important to maintaining the Painted Bunting population in the southeastern US.","language":"English","publisher":"Humboldt Field Research Institute","publisherLocation":"Steuben, ME","doi":"10.1656/058.010.0213","usgsCitation":"Meyers, J.M., 2011, Population densities of painted buntings in the southeastern United States: Southeastern Naturalist, v. 10, no. 2, p. 345-356, https://doi.org/10.1656/058.010.0213.","productDescription":"12 p.","startPage":"345","endPage":"356","numberOfPages":"12","temporalStart":"2003-05-13","temporalEnd":"2003-06-26","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":204521,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Florida, Georgia, North Carolina, South Carolina","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -80.068359375,\n              25.12539261151203\n            ],\n            [\n              -81.123046875,\n              31.16580958786196\n            ],\n            [\n              -75.89355468749999,\n              35.92464453144099\n            ],\n            [\n              -77.080078125,\n              36.527294814546245\n            ],\n            [\n              -81.6943359375,\n              36.491973470593685\n            ],\n            [\n              -84.4189453125,\n              35.35321610123823\n            ],\n            [\n              -85.4296875,\n              35.06597313798418\n            ],\n            [\n              -85.3857421875,\n              32.32427558887655\n            ],\n            [\n              -85.0341796875,\n              30.751277776257812\n            ],\n            [\n              -88.1982421875,\n              31.090574094954192\n            ],\n            [\n              -88.0224609375,\n              30.56226095049944\n            ],\n            [\n              -86.044921875,\n              30.107117887092357\n            ],\n            [\n              -85.0341796875,\n              29.6880527498568\n            ],\n            [\n              -84.0234375,\n              29.878755346037977\n            ],\n            [\n              -82.880859375,\n              28.8831596093235\n            ],\n            [\n              -82.6171875,\n              27.371767300523047\n            ],\n            [\n              -81.1669921875,\n              25.12539261151203\n            ],\n            [\n              -80.068359375,\n              25.12539261151203\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"10","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4aa7e4b07f02db667049","contributors":{"authors":[{"text":"Meyers, J.

To understand the spatial scales and identify specific environmental factors that determine risks of parasitism in frogs, helminth communities in metamorphic frogs of the northern leopard frog (<i>Rana pipiens</i>) were examined in relation to wetland and landscape factors at local (1 km) and regional (10 km) spatial extents in an agricultural region of Minnesota (USA) using regression analyses, ordination, and variance partitioning techniques. Greater amounts of forested and woody wetland habitats, shorter distances between woody wetlands, and smaller-sized open water patches in surrounding landscapes were the most consistently positive correlates with the abundances, richness, and diversity of helminths found in the frogs. Wetland and local landscape variables were suggested as most important for larval trematode abundances, whereas local and regional landscape variables appeared most important for adult helminths. As previously reported, the sum concentration of atrazine and its metabolite desethylatrazine, was the strongest predictor of larval trematode communities. In this report, we highlight the additional influences of landscape factors. In particular, our data suggest that anthropogenic activities that have resulted in the loss of the availability and connectivity of suitable habitats in the surrounding landscapes of wetlands are associated with declines in helminth richness and abundance, but that alteration of wetland water quality through eutrophication or pesticide contamination may facilitate the transmission of certain parasite taxa when they are present at wetlands. Although additional research is needed to quantify the negative effects of parasitism on frog populations, efforts to reduce inputs of agrochemicals into wetlands to limit larval trematode infections may be warranted, given the current high rates of amphibian declines and extinction events.</p>","language":"English","publisher":"Ecological Society of

Whether noncervid species can be infected by CWD and thereby serve as reservoirs for the infection is not known. To investigate this issue, we previously used serial protein misfolding cyclic amplification (sPMCA) to demonstrate that CWD prions can amplify in brain homogenates from several species sympatric with cervids, including prairie voles (</span><i><span id=\"named-content-1\" class=\"named-content genus-species\">Microtus ochrogaster</span></i><span>) and field mice (</span><i><span id=\"named-content-2\" class=\"named-content genus-species\">Peromyscus</span></i><span><i>&nbsp;spp.</i>). Here, we show that prairie voles are susceptible to mule deer CWD prions&nbsp;</span><i>in vivo</i><span>&nbsp;and that sPMCA amplification of CWD prions in vole brain enhances the infectivity of CWD for this species. Prairie voles inoculated with sPMCA products developed clinical signs of TSE disease approximately 300 days prior to, and more consistently than, those inoculated with CWD prions from deer brain. Moreover, the deposition patterns and biochemical properties of protease-resistant form of PrP (PrP</span><sup>RES</sup><span>) in the brains of affected voles differed from those in cervidized transgenic (CerPrP) mice infected with CWD. In addition, voles inoculated orally with sPMCA products developed clinical signs of TSE and were positive for PrP</span><sup>RES</sup><span>&nbsp;deposition, whereas those inoculated orally with deer-origin CWD prions did not. These results demonstrate that transspecies sPMCA of CWD prions can enhance the infectivity and adapt the host range of CWD prions and thereby may be useful to assess determinants of prion species barriers.</span></p>","language":"English","publisher":"American Society for Microbiology","publisherLocation":"Washington, D.C.","doi":"10.1128/JVI.00809-11","usgsCitation":"Kurt, T.D., Seelig, D.M., Schneider, J.R., Johnson, C.J., Telling, G.C., Heisey, D.M., and Hoover, E.A., 2011, Alteration of the chronic wasting disease species barrier by in vitro prion amplification: Journal of Virology, v. 85, no. 17, p. 8528-8537, https://doi.org/10.1128/JVI.00809-11.","productDescription":"10 p.","startPage":"8528","endPage":"8537","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":456,"text":"National Wildlife Health Center","active":true,"usgs":true}],"links":[{"id":474909,"rank":1,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://doi.org/10.1128/jvi.00809-11","text":"External Repository"},{"id":204522,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"85","issue":"17","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4adee4b07f02db6874fa","contributors":{"authors":[{"text":"Kurt, Timothy D.","contributorId":52711,"corporation":false,"usgs":true,"family":"Kurt","given":"Timothy","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":352929,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Seelig, Davis M.","contributorId":44664,"corporation":false,"usgs":true,"family":"Seelig","given":"Davis","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":352926,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Schneider, Jay R. jrschneider@usgs.gov","contributorId":5512,"corporation":false,"usgs":true,"family":"Schneider","given":"Jay","email":"jrschneider@usgs.gov","middleInitial":"R.","affiliations":[{"id":456,"text":"National Wildlife Health Center","active":true,"usgs":true}],"preferred":true,"id":352925,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Johnson, Christopher J. cjjohnson@usgs.gov","contributorId":3491,"corporation":false,"usgs":true,"family":"Johnson","given":"Christopher","email":"cjjohnson@usgs.gov","middleInitial":"J.","affiliations":[{"id":456,"text":"National Wildlife Health Center","active":true,"usgs":true}],"preferred":true,"id":352924,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Telling, Glenn C.","contributorId":49100,"corporation":false,"usgs":true,"family":"Telling","given":"Glenn","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":352927,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Heisey, Dennis M. dheisey@usgs.gov","contributorId":2455,"corporation":false,"usgs":true,"family":"Heisey","given":"Dennis","email":"dheisey@usgs.gov","middleInitial":"M.","affiliations":[{"id":456,"text":"National Wildlife Health Center","active":true,"usgs":true}],"preferred":true,"id":352923,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Hoover, Edward A.","contributorId":52316,"corporation":false,"usgs":true,"family":"Hoover","given":"Edward","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":352928,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

Tests that assign an individual's genotype to its most likely source population are increasingly used. Here we show how to augment a superpopulation capture-recapture model with such information. We consider a single superpopulation model without age structure, and split each entry probability into separate components due to births in situ and immigration. We show that it is possible to estimate these two probabilities separately. We first consider the case of perfect information about population of origin, where we can distinguish individuals born in situ from immigrants with certainty. Then we consider the more realistic case of imperfect information, where we use genetic or other information to assign probabilities to each individual's origin as in situ or outside the population. We use a resampling approach to impute the true population of origin from imperfect assignment information. The integration of data on population of origin with capture-recapture data allows us to determine the contributions of immigration and in situ reproduction to the growth of the population, an issue of importance to ecologists. We illustrate our new models with capture-recapture and genetic assignment data from a population of banner-tailed kangaroo rats Dipodomys spectabilis in Arizona.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Biometrics","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","publisherLocation":"Hoboken, NJ","usgsCitation":"Wen, Z., Pollock, K., Nichols, J., and Waser, P., 2011, Augmenting superpopulation capture-recapture models with population assignment data: Biometrics, v. 67, no. 3, p. 691-700.","productDescription":"10 p.","startPage":"691","endPage":"700","numberOfPages":"10","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":204446,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":94370,"rank":700,"type":{"id":15,"text":"Index Page"},"url":"https://onlinelibrary.wiley.com/doi/10.1111/j.1541-0420.2010.01522.x/abstract","linkFileType":{"id":1,"text":"pdf"}}],"volume":"67","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a8fe4b07f02db655602","contributors":{"authors":[{"text":"Wen, Zhi","contributorId":30348,"corporation":false,"usgs":true,"family":"Wen","given":"Zhi","email":"","affiliations":[],"preferred":false,"id":352847,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Pollock, Kenneth","contributorId":38273,"corporation":false,"usgs":true,"family":"Pollock","given":"Kenneth","affiliations":[],"preferred":false,"id":352849,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Nichols, James","contributorId":26059,"corporation":false,"usgs":true,"family":"Nichols","given":"James","affiliations":[],"preferred":false,"id":352846,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Waser, Peter","contributorId":30745,"corporation":false,"usgs":true,"family":"Waser","given":"Peter","email":"","affiliations":[],"preferred":false,"id":352848,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

These data, uncovered in Afghanistan, represent magnetic and electrical ground surveys for which locations are not well defined. Due to lack of location information, these surveys were georeferenced using the cities, rivers, and surrounding geology found on the maps used to plot survey locations. A geologic map found in the Soviet report contains profile lines that correspond to the geophysical maps, allowing these data to be georeferenced. The profiles correspond to sets of resistivity, chargeabiliy, and magnetic data. Some datasets were presented as graphs and needed to be gridded into a useable image. Only the vertical component of the magnetic field was collected, so conversion to total field anomaly was necessary. The magnetic data were collected in either gammas or milliorstead, both of which required conversion to standard SI units. To be useful to modern studies, the datasets and images contained in this report have been digitized, georeferenced, and in some cases converted into computer-ready formats.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr20111270","usgsCitation":"Polster, S.W., and Drenth, B.J., 2011, Digitized data from ground geophysical surveys in Afghanistan: A website for distribution of data: U.S. Geological Survey Open-File Report 2011-1270, iii, 18 p.; Appendix 1; Digital Data, https://doi.org/10.3133/ofr20111270.","productDescription":"iii, 18 p.; Appendix 1; Digital Data","additionalOnlineFiles":"Y","costCenters":[{"id":211,"text":"Crustal Geophysics and Geochemistry Science Center","active":true,"usgs":true}],"links":[{"id":116560,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr_2011_1270.png"},{"id":94362,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2011/1270/","linkFileType":{"id":5,"text":"html"}}],"country":"United States","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 60,29 ], [ 60,39 ], [ 75,39 ], [ 75,29 ], [ 60,29 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a82e4b07f02db64ac87","contributors":{"authors":[{"text":"Polster, Sarah W.","contributorId":26427,"corporation":false,"usgs":true,"family":"Polster","given":"Sarah","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":353075,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Drenth, Benjamin J. 0000-0002-3954-8124 bdrenth@usgs.gov","orcid":"https://orcid.org/0000-0002-3954-8124","contributorId":1315,"corporation":false,"usgs":true,"family":"Drenth","given":"Benjamin","email":"bdrenth@usgs.gov","middleInitial":"J.","affiliations":[{"id":211,"text":"Crustal Geophysics and Geochemistry Science Center","active":true,"usgs":true}],"preferred":true,"id":353074,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

In this part of the northern Cordillera, extensive mid-Cretaceous postcollisional plutonism took place following the accretion of exotic terranes to the continental margin. The most cratonward of the resulting plutonic belts comprises small isolated intrusive centers, with compositionally diverse, dominantly potassic rocks, as exemplified at Scheelite Dome, located in central Yukon. Similar to other spatially and temporally related intrusive centers, the Scheelite Dome intrusions are genetically associated with intrusion-related gold deposits.</p><p>Intrusions have exceptional variability, ranging from volumetrically dominant clinopyroxene-bearing monzogranites, to calc-alkaline minettes and spessartites, with an intervening range of intermediate to felsic stocks and dikes, including leucominettes, quartz monzonites, quartz monzodiorites, and granodiorites. All rock types are potassic, are strongly enriched in LILEs and LREEs, and feature high LILE/HFSE ratios. Clinopyroxene is common to all rock types and ranges from salite in felsic rocks to high Mg augite and Cr-rich diopside in lamprophyres. Less common, calcic amphibole ranges from actinolitic hornblende to pargasite. The rocks have strongly radiogenic Sr (initial<span>&nbsp;</span><sup>87</sup>Sr/<sup>86</sup>Sr from 0.711-0.714) and Pb isotope ratios (<sup>206</sup>Pb/<sup>204</sup>Pb from 19.2-19.7), and negative initial ɛ<sub>Nd</sub><span>&nbsp;</span>values (−8.06 to −11.26).</p><p>Whole-rock major and trace element, radiogenic isotope, and mineralogical data suggest that the felsic to intermediate rocks were derived from mafic potassic magmas sourced from the lithospheric mantle via fractional crystallization and minor assimilation of metasedimentary crust. Mainly unmodified minettes and spessartites represent the most primitive and final phases emplaced. Metasomatic enrichments in the underlying lithospheric mantle are attributes of the ancient North American cratonic margin that appear to be essential prerequisites to this style of postcollisional magmatism and associated gold-rich fluid exsolution. This type of magmatic hydrothermal activity occurs in a very specific tectonic setting that typically sets intrusion-related gold deposits apart from orogenic gold deposits, which are synorogenic in timing and have no consistent direct relationship to such diverse and contemporaneous lithospheric mantle-derived magmas, although they too are commonly sited adjacent to lithospheric boundaries.</p>","language":"English","publisher":"Society of Economic Geologists","doi":"10.2113/econgeo.106.3.451","usgsCitation":"Mair, J.L., Farmer, G.L., Groves, D.I., Hart, C.J., and Goldfarb, R.J., 2011, Petrogenesis of postcollisional magmatism at Scheelite Dome, Yukon, Canada: Evidence for a lithospheric mantle source for magmas associated with intrusion-related gold systems: Economic Geology, v. 106, no. 3, p. 451-480, https://doi.org/10.2113/econgeo.106.3.451.","productDescription":"30 p.","startPage":"451","endPage":"480","numberOfPages":"30","costCenters":[{"id":171,"text":"Central Mineral and Environmental Resources Science Center","active":true,"usgs":true}],"links":[{"id":204398,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Canada","state":"Yukon","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -140.2734375,\n              66.24916310923315\n            ],\n            [\n              -140.5810546875,\n              66.28453710088559\n            ],\n            [\n              -140.009765625,\n              63.52897054110277\n            ],\n            [\n              -133.0224609375,\n              60.02095215374802\n            ],\n            [\n              -126.826171875,\n              60.13056361691419\n            ],\n            [\n              -126.60644531250001,\n              60.392147922518845\n            ],\n            [\n              -131.044921875,\n              64.09140752262307\n            ],\n            [\n              -140.2734375,\n              66.24916310923315\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"106","issue":"3","noUsgsAuthors":false,"publicationDate":"2011-05-13","publicationStatus":"PW","scienceBaseUri":"4f4e4ae0e4b07f02db688004","contributors":{"authors":[{"text":"Mair, John L.","contributorId":61715,"corporation":false,"usgs":false,"family":"Mair","given":"John","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":350725,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Farmer, G.

Time-space-composition relations for the ancestral Cascades arc have been synthesized from a recent compilation of more than 4000 geochemical analyses and associated age data. Neither the composition nor distribution of ancestral Cascades magmatism was uniform along the length of the ancestral arc through time. Initial (&gt;40 to 36 Ma) ancestral Cascades magmatism (mostly basalt and basaltic andesite) was focused at the north end of the arc between the present-day locations of Mount Rainier and the Columbia River. From 35 to 18 Ma, initial basaltic andesite and andesite magmatism evolved to include dacite and rhyolite; magmatic activity became more voluminous and extended along most of the arc. Between 17 and 8 Ma, magmatism was focused along the part of the arc coincident with the northern two-thirds of Oregon and returned to more mafic compositions. Subsequent ancestral Cascades magmatism was dominated by basaltic andesite to basalt prior to the post–4 Ma onset of High Cascades magmatism. Transitional tholeiitic to calc-alkaline compositions dominated early (before 40 to ca. 25 Ma) ancestral Cascades eruptive products, whereas the majority of the younger arc rocks have a calc-alkaline affinity. Tholeiitic compositions characteristic of the oldest ancestral arc magmas suggest development associated with thin, immature crust and slab window processes, whereas the younger, calc-alkaline magmas suggest interaction with thicker, more evolved crust and more conventional subduction-related magmatic processes. Presumed changes in subducted slab dip through time also correlate with fundamental magma composition variation. The predominance of mafic compositions during latest ancestral arc magmatism and throughout the history of modern High Cascades magmatism probably reflects extensional tectonics that dominated during these periods of arc magmatism.</p><p>Mineral deposits associated with ancestral Cascades arc rocks are uncommon; most are small and low grade relative to those found in other continental magmatic arcs. The small size, low grade, and dearth of deposits, especially in the southern two-thirds of the ancestral arc, probably reflect many factors, the most important of which may be the prevalence of extensional tectonics within this arc domain during this magmatic episode. Progressive clockwise rotation of the forearc block west of the evolving Oregon part of the ancestral Cascades magmatism produced an extensional regime that did not foster significant mineral deposit formation. In contrast, the Washington arc domain developed in a transpressional to mildly compressive regime that was more conducive to magmatic processes and hydrothermal fluid channeling critical to deposit formation. Small, low-grade porphyry copper deposits in the northern third of the ancestral Cascades arc segment also may be a consequence of more mature continental crust, including a Mesozoic component, beneath Washington north of Mount St. Helens.</p>","language":"English","publisher":"Geological Society of America","publisherLocation":"Boulder, CO","doi":"10.1130/GES00669.1","usgsCitation":"du Bray, E.A., and John, D.A., 2011, Petrologic, tectonic, and metallogenic evolution of the Ancestral Cascades magmatic arc, Washington, Oregon, and northern California: Geosphere, v. 7, no. 5, p. 1102-1133, https://doi.org/10.1130/GES00669.1.","productDescription":"32 p.","startPage":"1102","endPage":"1133","numberOfPages":"32","costCenters":[{"id":171,"text":"Central Mineral and Environmental Resources Science Center","active":true,"usgs":true}],"links":[{"id":488796,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1130/ges00669.1","text":"Publisher Index Page"},{"id":204419,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California, Oregon, Washington","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -119.88281249999999,\n              49.03786794532644\n            ],\n            [\n              -123.06884765625,\n              48.96579381461063\n            ],\n            [\n              -123.59619140625001,\n              48.180738507303836\n            ],\n            [\n              -124.892578125,\n              48.45835188280866\n            ],\n            [\n              -124.03564453125,\n              45.5679096098613\n            ],\n            [\n              -124.76074218749999,\n              42.79540065303723\n            ],\n            [\n              -124.5849609375,\n              40.44694705960048\n            ],\n            [\n              -120.89355468749999,\n              39.842286020743394\n            ],\n            [\n              -120.47607421874999,\n              42.00032514831621\n            ],\n            [\n              -119.99267578124999,\n              43.45291889355465\n            ],\n            [\n              -119.88281249999999,\n              49.03786794532644\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"7","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b1ae4b07f02db6a81f6","contributors":{"authors":[{"text":"du Bray, Edward A. 0000-0002-4383-8394 edubray@usgs.gov","orcid":"https://orcid.org/0000-0002-4383-8394","contributorId":755,"corporation":false,"usgs":true,"family":"du Bray","given":"Edward","email":"edubray@usgs.gov","middleInitial":"A.","affiliations":[{"id":171,"text":"Central Mineral and Environmental Resources Science Center","active":true,"usgs":true},{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":353050,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"John, David A. 0000-0001-7977-9106 djohn@usgs.gov","orcid":"https://orcid.org/0000-0001-7977-9106","contributorId":1748,"corporation":false,"usgs":true,"family":"John","given":"David","email":"djohn@usgs.gov","middleInitial":"A.","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":353051,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The physical-properties program analyzed core samples recovered from the well, and in conjunction with downhole geophysical logs, produced an extensive dataset including grain size, water content, porosity, grain density, bulk density, permeability, X-ray diffraction (XRD) mineralogy, nuclear magnetic resonance (NMR), and petrography. This study documents the physical property interrelationships in the well and demonstrates their correlation with the occurrence of gas hydrate. Gas hydrate (GH) occurs in three unconsolidated, coarse silt to fine sand intervals within the Paleocene and Eocene beds of the Sagavanirktok Formation: Unit D-GH (614.4 m-627.9 m); unit C-GH1 (649.8 m-660.8 m); and unit C-GH2 (663.2 m-666.3 m). These intervals are overlain by fine to coarse silt intervals with greater clay content. A deeper interval (unit B) is similar lithologically to the gas-hydrate-bearing strata; however, it is water-saturated and contains no hydrate. In this system it appears that high sediment permeability (k) is critical to the formation of concentrated hydrate deposits. Intervals D-GH and C-GH1 have average \"plug\" intrinsic permeability to nitrogen values of 1700 mD and 675 mD, respectively. These values are in strong contrast with those of the overlying, gas-hydrate-free sediments, which have k values of 5.7 mD and 49 mD, respectively, and thus would have provided effective seals to trap free gas. The relation between permeability and porosity critically influences the occurrence of GH. For example, an average increase of 4% in porosity increases permeability by an order of magnitude, but the presence of a second fluid (e.g., methane from dissociating gas hydrate) in the reservoir reduces permeability by more than an order of magnitude.","language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/j.marpetgeo.2010.01.008","usgsCitation":"Winters, W.J., Walker, M., Hunter, R., Collett, T.S., Boswell, R.M., Rose, K.K., Waite, W., Torres, M., Patil, S., and Dandekar, A., 2011, Physical properties of sediment from the Mount Elbert Gas Hydrate Stratigraphic Test Well, Alaska North Slope: Journal of Marine and Petroleum Geology, v. 28, no. 2, p. 361-380, https://doi.org/10.1016/j.marpetgeo.2010.01.008.","productDescription":"20 p.","startPage":"361","endPage":"380","costCenters":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":474912,"rank":1,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://hdl.handle.net/1912/4400","text":"External Repository"},{"id":204542,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","volume":"28","issue":"2","edition":"2011","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4adbe4b07f02db685b1a","contributors":{"authors":[{"text":"Winters, William J. bwinters@usgs.gov","contributorId":522,"corporation":false,"usgs":true,"family":"Winters","given":"William","email":"bwinters@usgs.gov","middleInitial":"J.","affiliations":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":true,"id":348209,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Walker, Michael","contributorId":7755,"corporation":false,"usgs":true,"family":"Walker","given":"Michael","affiliations":[],"preferred":false,"id":348212,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hunter, Robert","contributorId":50285,"corporation":false,"usgs":true,"family":"Hunter","given":"Robert","affiliations":[],"preferred":false,"id":348214,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Collett, Timothy S. 0000-0002-7598-4708 tcollett@usgs.gov","orcid":"https://orcid.org/0000-0002-7598-4708","contributorId":1698,"corporation":false,"usgs":true,"family":"Collett","given":"Timothy","email":"tcollett@usgs.gov","middleInitial":"S.","affiliations":[{"id":255,"text":"Energy Resources Program","active":true,"usgs":true},{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true},{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true},{"id":171,"text":"Central Mineral and Environmental Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":348211,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Boswell, Ray M.","contributorId":72926,"corporation":false,"usgs":true,"family":"Boswell","given":"Ray","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":348215,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Rose, Kelly K.","contributorId":82452,"corporation":false,"usgs":true,"family":"Rose","given":"Kelly","email":"","middleInitial":"K.","affiliations":[],"preferred":false,"id":348216,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Waite, William F. 0000-0002-9436-4109 wwaite@usgs.gov","orcid":"https://orcid.org/0000-0002-9436-4109","contributorId":625,"corporation":false,"usgs":true,"family":"Waite","given":"William F.","email":"wwaite@usgs.gov","affiliations":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true},{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true}],"preferred":true,"id":348210,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Torres, Marta","contributorId":86477,"corporation":false,"usgs":true,"family":"Torres","given":"Marta","affiliations":[],"preferred":false,"id":348217,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Patil, Shirish","contributorId":86478,"corporation":false,"usgs":true,"family":"Patil","given":"Shirish","email":"","affiliations":[],"preferred":false,"id":348218,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Dandekar, Abhijit","contributorId":22896,"corporation":false,"usgs":true,"family":"Dandekar","given":"Abhijit","email":"","affiliations":[],"preferred":false,"id":348213,"contributorType":{"id":1,"text":"Authors"},"rank":10}]}}

Herein we document the occurrence of unusual FAs (polymethylene-interrupted fatty acids; PMI-FAs) in select freshwater organisms in the Laurentian Great Lakes. We did not detect PMI-FAs in: (a) natural seston from Lake Erie and Hamilton Harbor (Lake Ontario), (b) various species of laboratory-cultured algae including a green alga (<i>Scenedesmus obliquus</i>), two cyanobacteria (<i>Aphanizomenon flos-aquae</i> and <i>Synechococystis</i> sp.), two diatoms (<i>Asterionella formosa</i>, <i>Diatoma elongatum</i>) and a chrysophyte (<i>Dinobryon cylindricum</i>) or, (c) zooplankton (<i>Daphnia</i> spp., calanoid or cyclopoid copepods) from Lake Ontario, suggesting that PMI-FAs are not substantively incorporated into consumers at the phytoplankton&ndash;zooplankton interface. However, these unusual FAs comprised 4-6% of total fatty acids (on a dry tissue weight basis) of native fat mucket (<i>Lampsilis siliquoidea</i>) and plain pocketbook (<i>L. cardium</i>) mussels and in invasive zebra (<i>Dreissena polymorpha</i>) and quagga (<i>D. bugensis</i>) mussels. We were able to clearly partition Great Lakes' mussels into three separate groups (zebra, quagga, and native mussels) based solely on their PMI-FA profiles. We also provide evidence for the trophic transfer of PMI-FAs from mussels to various fishes in Lakes Ontario and Michigan, further underlining the potential usefulness of PMI-FAs for tracking the dietary contribution of mollusks in food web and contaminant-fate studies.","language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam,

Plasma cortisol, glucose, and osmolality were measured over 24 h and at 14 d posthandling after exposing bonytail to KCl and one net stressor (capture with a net), KCl plus formalin and two net stressors, and one or two net stressors without chemicals. Elevated plasma cortisol (322–440 ng/mL) and glucose (254–399 mg/dL) concentrations were observed in all treatments compared with the concentrations in control fish (plasma cortisol, 56 ng/mL; glucose, 43 mg/dL). While there were no detectable differences in plasma osmolality among the treatment and control fish, a difference was observed between fish that were handled once versus twice. Chemical effects of stress were not observed in any of the physiological responses when the KCl treatment was compared with the one-net stressor treatment or when the KCl plus formalin treatment was compared with the two-net stressor treatment. Cumulative responses, however, were observed between one net stressor and two net stressors for plasma glucose and osmolality but not for plasma cortisol. Plasma cortisol and glucose levels remained elevated at 24 h posthandling, indicating that bonytail had not completely recovered from the handling stressors and would benefit from a recovery period in protected refugia before being released.</span></p>","language":"English","publisher":"Taylor & Francis","publisherLocation":"Philadelphia, PA","doi":"10.1080/02755947.2011.576201","usgsCitation":"Sykes, C.L., Caldwell, C.A., and Gould, W., 2011, Physiological effects of potassium chloride, formalin and handling stress on bonytail: North American Journal of Fisheries Management, v. 31, no. 2, p. 291-298, https://doi.org/10.1080/02755947.2011.576201.","productDescription":"7 p.","startPage":"291","endPage":"298","ipdsId":"IP-025136","costCenters":[{"id":204,"text":"Cooperative Research Unit Seattle","active":false,"usgs":true}],"links":[{"id":204540,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"31","issue":"2","noUsgsAuthors":false,"publicationDate":"2011-04-21","publicationStatus":"PW","scienceBaseUri":"4f4e4adbe4b07f02db685a68","contributors":{"authors":[{"text":"Sykes, Catherine L.","contributorId":59936,"corporation":false,"usgs":true,"family":"Sykes","given":"Catherine","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":346870,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Caldwell, Colleen A. 0000-0002-4730-4867 ccaldwel@usgs.gov","orcid":"https://orcid.org/0000-0002-4730-4867","contributorId":3050,"corporation":false,"usgs":true,"family":"Caldwell","given":"Colleen","email":"ccaldwel@usgs.gov","middleInitial":"A.","affiliations":[{"id":200,"text":"Coop Res Unit Seattle","active":true,"usgs":true}],"preferred":true,"id":346869,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Gould, William R.","contributorId":63780,"corporation":false,"usgs":true,"family":"Gould","given":"William R.","affiliations":[],"preferred":false,"id":346871,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The Corsica River Estuary represents a coastal lowland setting typical of much of the eastern bay. An interdisciplinary U.S. Geological Survey (USGS) science team conducted field operations in the lower estuary in April and May 2007. Resource managers are concerned about nutrients that are entering the estuary via SGD that may be contributing to eutrophication, harmful algal blooms, and fish kills. Techniques employed in the study included continuous resistivity profiling (CRP), piezometer sampling of submarine groundwater, and collection of a time series of radon tracer activity in surface water. A CRP system measures electrical resistivity of saturated subestuarine sediments to distinguish those bearing fresh water (high resistivity) from those with saline or brackish pore water (low resistivity). This report describes the collection and processing of CRP data and summarizes the results. Based on a grid of 67.6 kilometers of CRP data, low-salinity (high-resistivity) groundwater extended approximately 50-400 meters offshore from estuary shorelines at depths of 5 to >12 meters below the sediment surface, likely beneath a confining unit. A band of low-resistivity sediment detected along the axis of the estuary indicated the presence of a filled paleochannel containing brackish groundwater. The meandering paleochannel likely incised through the confining unit during periods of lower sea level, allowing the low-salinity groundwater plumes originating from land to mix with brackish subestuarine groundwater along the channel margins and to discharge. A better understanding of the spatial variability and geological controls of submarine groundwater flow beneath the Corsica River Estuary could lead to improved models and mitigation strategies for nutrient over-enrichment in the estuary and in other similar settings.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr20101094","usgsCitation":"Cross, V., Bratton, J., Worley, C., Crusius, J., and Kroeger, K., 2011, Continuous resistivity profiling data from the Corsica River Estuary, Maryland: U.S. Geological Survey Open-File Report 2010-1094, HTML Document; DVD-ROM, https://doi.org/10.3133/ofr20101094.","productDescription":"HTML Document; DVD-ROM","temporalStart":"2007-04-01","temporalEnd":"2007-05-31","costCenters":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":116026,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr_2010_1094.gif"},{"id":94293,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2010/1094/","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Maryl","otherGeospatial":"Corsica River Estuary","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -76.15083333333334,39.05 ], [ -76.15083333333334,39.1 ], [ -76.1,39.1 ], [ -76.1,39.05 ], [ -76.15083333333334,39.05 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4afde4b07f02db696aac","contributors":{"authors":[{"text":"Cross, V.A.","contributorId":88687,"corporation":false,"usgs":true,"family":"Cross","given":"V.A.","email":"","affiliations":[],"preferred":false,"id":353055,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bratton, J.F.","contributorId":94354,"corporation":false,"usgs":true,"family":"Bratton","given":"J.F.","email":"","affiliations":[],"preferred":false,"id":353056,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Worley, C.R.","contributorId":43479,"corporation":false,"usgs":true,"family":"Worley","given":"C.R.","email":"","affiliations":[],"preferred":false,"id":353054,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Crusius, John 0000-0003-2554-0831 jcrusius@usgs.gov","orcid":"https://orcid.org/0000-0003-2554-0831","contributorId":2155,"corporation":false,"usgs":true,"family":"Crusius","given":"John","email":"jcrusius@usgs.gov","affiliations":[{"id":119,"text":"Alaska Science Center Geology Minerals","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":353053,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Kroeger, K.D.","contributorId":26060,"corporation":false,"usgs":true,"family":"Kroeger","given":"K.D.","email":"","affiliations":[],"preferred":false,"id":353052,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

The New Madrid earthquakes of 1811-1812, over 180 kilometers (km) from Evansville, produced ground motions with a Modified Mercalli Intensity of VII near Evansville, the highest intensity observed in Indiana. Liquefaction evidence has been documented less than 40 km away from Evansville resulting from two large earthquakes in the past 12,000 years in the Wabash Valley. Two earthquake scenarios are described in this paper that demonstrate the expected ground motions for a 33&times;42-km region around Evansville based on a repeat earthquake from each of these source regions. We perform a one-dimensional analysis for a grid of sites that takes into account the amplification or deamplification of ground motion in the unconsolidated soil layer using a new three-dimensional model of seismic velocity and bedrock depth. There are significant differences in the calculated amplification from that expected for National Earthquake Hazard Reduction Program site class D conditions, with deamplification at many locations within the ancient bedrock valley underlying Evansville. Ground motions relative to the acceleration of gravity (g) in the Evansville area from a simulation of a magnitude (M) 7.7 New Madrid earthquake range from 0.15 to 0.25 g for peak ground acceleration, 0.14 to 0.7 g for 0.2-second (s) spectral acceleration, and 0.05 to 0.25 g for 1.0-s spectral acceleration. Ground motions from a M6.8 Wabash Valley earthquake centered 40 km northwest of the city produce ground motions that decrease with distance from 1.5 to 0.3 g for 0.2-s spectral acceleration when they reach the main part of Evansville, but then increase in amplitude from 0.3 to 0.6 g south of the city and the Ohio River. The densest urbanization in Evansville and Henderson, Ky., is within the area of preferential amplification at 1.0-s period for both scenarios, but the area experiences relatively less amplification than surrounding areas at 0.2 s, consistent with expected resonance periods based on the soil profiles.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr20111260","collaboration":"In collaboration with the Evansville Area Earthquake Hazards Mapping Project (EAEHMP)","usgsCitation":"Haase, J.S., Nowack, R.L., Cramer, C.H., Boyd, O.S., and Bauer, R., 2011, Earthquake scenario ground motions for the urban area of Evansville, Indiana: U.S. Geological Survey Open-File Report 2011-1260, iv, 17 p., https://doi.org/10.3133/ofr20111260.","productDescription":"iv, 17 p.","onlineOnly":"Y","costCenters":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"links":[{"id":116027,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr_2011_1260.gif"},{"id":94294,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2011/1260/","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Indiana","city":"Evansville","otherGeospatial":"Wabash Valley Seismic Zone;New Madrid Seismic Zone","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -91,35 ], [ -91,41 ], [ -85,41 ], [ -85,35 ], [ -91,35 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a51e4b07f02db629792","contributors":{"authors":[{"text":"Haase, Jennifer S.","contributorId":81238,"corporation":false,"usgs":true,"family":"Haase","given":"Jennifer","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":353062,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Nowack, Robert L.","contributorId":100516,"corporation":false,"usgs":true,"family":"Nowack","given":"Robert","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":353064,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Cramer, Chris H.","contributorId":32196,"corporation":false,"usgs":true,"family":"Cramer","given":"Chris","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":353061,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Boyd, Oliver S. olboyd@usgs.gov","contributorId":956,"corporation":false,"usgs":true,"family":"Boyd","given":"Oliver","email":"olboyd@usgs.gov","middleInitial":"S.","affiliations":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":false,"id":353060,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Bauer, Robert A.","contributorId":92412,"corporation":false,"usgs":true,"family":"Bauer","given":"Robert A.","affiliations":[],"preferred":false,"id":353063,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

In this U.S. Geological Survey study, done in cooperation with the U.S. Army Corps of Engineers, an existing calibrated CE-QUAL-W2 model of Detroit Lake (the impounded waterbody behind Detroit Dam) was used to determine how changes in dam operation or changes to the structural release points of Detroit Dam might affect downstream water temperatures under a range of historical hydrologic and meteorological conditions.\nMany combinations of environmental, operational, and structural options were explored with the model. Two downstream temperature targets were used along with three sets of environmental forcing conditions representing normal, hot/dry, and cool/wet conditions. Three structural options were modeled, including the use of existing outlets, one hypothetical variable-elevation outlet such as a sliding gate, and a hypothetical combination of a floating outlet and a fixed-elevation outlet. Finally, four sets of operational guidelines were explored to gain an understanding of the effects of imposing different downstream minimum streamflows or managing the level of the lake with different timelines in autumn.\nSeveral conclusions can be made from these interim model scenarios:\n* Temperature targets just downstream of Detroit Dam can be met through a combination of new dam outlets or a delayed drawdown of the lake in autumn.\n* Spring and summer dam operations greatly affect the available release temperatures and operational flexibility later in the autumn. Releasing warm water during mid-summer tends to keep more cool water available for release in autumn.\n* The ability to meet downstream temperature targets during spring depends on the characteristics of the available outlets. Under existing conditions, for example, although warm water sometimes is present at the lake surface, such water may not be available for release if the lake level is either well below or well above the spillway crest in spring and early summer.\n* Managing lake releases to meet downstream temperature targets depends on having outlet structures that can access both (warm) lake surface water and (cold) deeper lake water throughout the year. The existing outlets at Detroit Dam do not allow near-surface waters to be released during times when the lake surface level is below the spillway (spring and autumn).\n* Model simulations indicate that delayed drawdown of Detroit Lake in autumn would result in better control over release temperatures.\n* Compared to the existing outlets at Detroit Dam, floating or sliding-gate outlet structures can provide greater control over release temperatures because they provide better access to warm water at the lake surface and cooler water at depth.\nThis report provides interim study results to the U.S. Army Corps of Engineers.

Although some of the salinity and selenium loading in the Montrose Arroyo study area is from natural sources, additional loading has resulted from the introduction of intensive irrigation in the water-shed. With increasing land-use change and the conversion from irrigated agricultural to urban land, land managers and stakeholders need information about the long-term effects of land-use change on salinity and selenium loading. In response to the need to advance salinity and selenium science, the U.S. Geological Survey, in cooperation with the Bureau of Reclamation, Colorado River Basin Salinity Control Forum, and Colorado River Water Conservation District, developed a study to characterize salinity and selenium loading and how salinity and selenium sources may relate to land-use change in Montrose Arroyo. This report characterizes changes in salinity and selenium loading to Montrose Arroyo from March 1992 to February 2010 and the magnitude of land-use change between unirrigated desert, irrigated agricultural, and urban land-use/land-cover types, and discusses how the respective loads may relate to land-use change. Montrose Arroyo is an approximately 8-square-mile watershed in Montrose County in western Colorado. Salinity and selenium were studied in Montrose Arroyo in a 2001 study as part of a salinity- and selenium-control lateral project. The robust nature of the historical dataset indicated that Montrose Arroyo was a prime watershed for a follow-up study. Two sites from the 2001 study were used to monitor salinity and selenium loads in Montrose Arroyo in the follow-up study. Over the period of 2 water years and respective irrigation seasons (2008-2010), 27 water-quality samples were collected and streamflow measurements were made at the historical sites MA2 and MA4. Salinity and selenium concen-trations, loads, and streamflow were compared between the pre-lateral-project and post-growth periods and between the post-lateral-project and post-growth periods.  No significant differences in streamflow, salinity (concen-tration and load), or selenium (concentration and load) were found at MA4 between the pre-lateral project and post-growth periods or between the post-lateral-project and post-growth periods. The statistical analysis indicated no significant dif-ferences in streamflow or salinity (both concentration and load) between the pre-lateral-project and post-growth periods or between the post-lateral-project and post-growth periods at MA2; however, selenium concentrations and loads were significantly greater between the pre-lateral-project and post-growth periods and between the post-lateral-project and post-growth periods at MA2. Land-use change between MA4 and MA2 may have contributed to the determined differences in selenium values, but the specific mechanisms causing the increases between periods are unknown.  The size of the urbanized area in Montrose Arroyo was quantified for 1993, 2002, and 2009 by using a geographic information system (GIS) with imagery from the specified years. The greatest change in land use from 1993 to 2009 was the increase of urban land due to conversion from irrigated agricultural land. The conversion of previously unirrigated desert to urban land or irrigated agriculture could become more common if urbanization and development expands into the eastern part of the watershed because a majority of the un-urbanized land in eastern Montrose Arroyo is unirrigated desert.  By applying GIS to the City of Montrose 2008 com-prehensive growth plan, it was estimated that approximately 786 acres of previously irrigated agricultural land will be converted to urban land and 689 acres of unirrigated desert will be converted to urban land under the plan scenario. New development on previously unirrigated land in shale areas would likely increase the potential for mobilization of sele-nium and salinity from new sources to Montrose Arroyo and the Lower Gunnison River Basin.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/sir20115106","collaboration":"Prepared in cooperation with the Bureau of Reclamation, the Colorado River Basin Salinity Control Forum, and the Colorado River Water Conservation District","usgsCitation":"Moore, J.L., 2011, Characterization of salinity and selenium loading and land-use change in Montrose Arroyo, western Colorado, from 1992 to 2010: U.S. Geological Survey Scientific Investigations Report 2011-5106, v, 23 p., https://doi.org/10.3133/sir20115106.","productDescription":"v, 23 p.","costCenters":[{"id":191,"text":"Colorado Water Science Center","active":true,"usgs":true}],"links":[{"id":116548,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/sir_2011_5106.png"},{"id":94299,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/sir/2011/5106/","linkFileType":{"id":5,"text":"html"}}],"scale":"1000000","state":"Colorado","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -108.83333333333333,37.833333333333336 ], [ -108.83333333333333,39.416666666666664 ], [ -107,39.416666666666664 ], [ -107,37.833333333333336 ], [ -108.83333333333333,37.833333333333336 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49a2e4b07f02db5beb92","contributors":{"authors":[{"text":"Moore, Jennifer L.","contributorId":68447,"corporation":false,"usgs":true,"family":"Moore","given":"Jennifer","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":353073,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

In order to understand this complex deformation, we have divided this region into five structural domains which are separated by four major boundary faults formed during four major periods of deformation related to oblique convergence of the India and Eurasia plates.\nThe five structural domains are (1) a foredeep, (2) a foreland fold-and-thrust belt, (3) a major deep trough that formed within the foreland fold-and-thrust belt and filled with collision molasse, (4) a thick flysch deposit, and (5) a subduction-obduction and related igneous rock terrane on the margin of the Eurasia plate (Afghan block).\nThe four major faults that bound the structural terrane are the Frontal (F), Ghazaband-Zhob (GZ), Gwal-Bagh (GB), and Chaman (C) faults. Four major periods of deformation are recognized: (1) emplacement of ophiolitic rocks onto the continental margin of the India plate; (2) convergence of the India-Eurasia plates; (3) deposition of Tertiary-Quaternary molasse units followed by major folding and thrusting, and formation of strike-slip faults; and (4) deposition of Pleistocene molasse units with subsequent folding, thrusting, and strike-slip motion that continues to the present.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr20111224","usgsCitation":"Maldonado, F., Mengal, J.M., Khan, S., and Warwick, P.D., 2011, Summary of the stratigraphy and structural elements related to plate convergence of the Quetta-Muslim Bagh-Sibi region, Balochistan, west-central Pakistan: U.S. Geological Survey Open-File Report 2011-1224, iii, 19 p., https://doi.org/10.3133/ofr20111224.","productDescription":"iii, 19 p.","onlineOnly":"Y","costCenters":[{"id":308,"text":"Geology and Environmental Change Science Center","active":false,"usgs":true}],"links":[{"id":116334,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr_2011_1224.gif"},{"id":94298,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2011/1224/","linkFileType":{"id":5,"text":"html"}}],"country":"Pakistan","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 62,25 ], [ 62,40 ], [ 78,40 ], [ 78,25 ], [ 62,25 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b15e4b07f02db6a4e9f","contributors":{"authors":[{"text":"Maldonado, Florian fmaldona@usgs.gov","contributorId":805,"corporation":false,"usgs":true,"family":"Maldonado","given":"Florian","email":"fmaldona@usgs.gov","affiliations":[],"preferred":true,"id":353070,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Mengal, Jan M.","contributorId":32667,"corporation":false,"usgs":true,"family":"Mengal","given":"Jan","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":353071,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Khan, Shahid H.","contributorId":98456,"corporation":false,"usgs":true,"family":"Khan","given":"Shahid H.","affiliations":[],"preferred":false,"id":353072,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Warwick, Peter D. 0000-0002-3152-7783 pwarwick@usgs.gov","orcid":"https://orcid.org/0000-0002-3152-7783","contributorId":762,"corporation":false,"usgs":true,"family":"Warwick","given":"Peter","email":"pwarwick@usgs.gov","middleInitial":"D.","affiliations":[{"id":241,"text":"Eastern Energy Resources Science Center","active":true,"usgs":true}],"preferred":false,"id":353069,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}
