Quantitative criteria serve as a critical basis for assessing the attainment of designated uses and measuring progress toward meeting water quality goals of the Chesapeake Bay Program partnership. In 1987, the Chesapeake Bay Program partnership committed to defining the water quality conditions necessary to protect aquatic living resources. Under section 303(c) of the Clean Water Act, States and authorized tribes have the primary responsibility for adopting water quality standards into law or regulation. The Chesapeake Bay Program partnership worked with U.S. Environmental Protection Agency to develop and publish a guidance framework of ambient water quality criteria with designated uses and assessment procedures for dissolved oxygen, water clarity, and chlorophyll a for Chesapeake Bay and its tidal tributaries in 2003. This article reviews the derivation of the water quality criteria, criteria assessment protocols, designated use boundaries, and their refinements published in six addendum documents since 2003 and successfully adopted into each jurisdiction's water quality standards used in developing the Chesapeake Bay Total Maximum Daily Load.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of the American Water Resources Association","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Journal of the American Water Resources Association","doi":"10.1111/jawr.12108","usgsCitation":"Tango, P.J., and Batiuk, R.A., 2013, Deriving Chesapeake Bay Water Quality Standards: Journal of the American Water Resources Association, v. 49, no. 5, p. 1007-1024, https://doi.org/10.1111/jawr.12108.","productDescription":"18 p.","startPage":"1007","endPage":"1024","ipdsId":"IP-046138","costCenters":[{"id":374,"text":"Maryland Water Science Center","active":true,"usgs":true}],"links":[{"id":278304,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":278300,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/jawr.12108"},{"id":278301,"type":{"id":15,"text":"Index Page"},"url":"https://onlinelibrary.wiley.com/doi/10.1111/jawr.12108/abstract"}],"country":"United States","otherGeospatial":"Chesapeake Bay","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -77.3175,36.9078 ], [ -77.3175,39.6076 ], [ -74.7591,39.6076 ], [ -74.7591,36.9078 ], [ -77.3175,36.9078 ] ] ] } } ] }","volume":"49","issue":"5","noUsgsAuthors":false,"publicationDate":"2013-09-04","publicationStatus":"PW","scienceBaseUri":"52663ee4e4b0992695a7f43a","contributors":{"authors":[{"text":"Tango, Peter J. pjtango@usgs.gov","contributorId":4088,"corporation":false,"usgs":true,"family":"Tango","given":"Peter","email":"pjtango@usgs.gov","middleInitial":"J.","affiliations":[{"id":374,"text":"Maryland Water Science Center","active":true,"usgs":true}],"preferred":true,"id":485026,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Batiuk, Richard A.","contributorId":8368,"corporation":false,"usgs":true,"family":"Batiuk","given":"Richard","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":485027,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

To help evaluate fracture flow and matrix–water exchange, we have determined U-series isotopic compositions on more than 40 drill core samples from 5 boreholes that represent discrete fracture surfaces, breccia zones, and interiors of unfractured core.  The U-series approach relies on the disruption of radioactive secular equilibrium between isotopes in the uranium-series decay chain due to preferential mobilization of <sup>234</sup>U relative to <sup>238</sup>U, and U relative to Th.  Samples from discrete fractures were obtained by milling fracture surfaces containing thin secondary mineral coatings of clays, silica, Fe–Mn oxyhydroxides, and zeolite. Intact core interiors and breccia fragments were sampled in bulk.  In addition, profiles of rock matrix extending 15 to 44 mm away from several fractures that show evidence of recent flow were analyzed to investigate the extent of fracture/matrix water exchange.  Samples of rock matrix have <sup>234</sup>U/<sup>238</sup>U and <sup>230</sup>Th/<sup>238</sup>U activity ratios (AR) closest to radioactive secular equilibrium indicating only small amounts of groundwater penetrated unfractured matrix. Greater U mobility was observed in welded-tuff matrix with elevated porosity and in zeolitized bedded tuff. Samples of brecciated core were also in secular equilibrium implying a lack of long-range hydraulic connectivity in these cases.  Samples of discrete fracture surfaces typically, but not always, were in radioactive disequilibrium. Many fractures had isotopic compositions plotting near the <sup>230</sup>Th-<sup>234</sup>U 1:1 line indicating a steady-state balance between U input and removal along with radioactive decay. Numerical simulations of U-series isotope evolution indicate that 0.5 to 1 million years are required to reach steady-state compositions. Once attained, disequilibrium <sup>234</sup>U/<sup>238</sup>U and <sup>230</sup>Th/<sup>238</sup>U AR values can be maintained indefinitely as long as hydrological and geochemical processes remain stable. Therefore, many Pahute Mesa fractures represent stable hydrologic pathways over million-year timescales. A smaller number of samples have non-steady-state compositions indicating transient conditions in the last several hundred thousand years. In these cases, U mobility is dominated by overall gains rather than losses of U.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Chemical Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.chemgeo.2013.08.043","usgsCitation":"Paces, J.B., Nichols, P.J., Neymark, L.A., and Rajaram, H., 2013, Evaluation of Pleistocene groundwater flow through fractured tuffs using a U-series disequilibrium approach, Pahute Mesa, Nevada, USA: Chemical Geology, v. 358, p. 101-118, https://doi.org/10.1016/j.chemgeo.2013.08.043.","productDescription":"18 p.","startPage":"101","endPage":"118","ipdsId":"IP-042487","costCenters":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"links":[{"id":278303,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":278299,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.chemgeo.2013.08.043"}],"country":"United States","state":"Nevada","otherGeospatial":"Pahute Mesa","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -117.245064,36.834569 ], [ -117.245064,38.186926 ], [ -115.957947,38.186926 ], [ -115.957947,36.834569 ], [ -117.245064,36.834569 ] ] ] } } ] }","volume":"358","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"52663ee6e4b0992695a7f440","contributors":{"authors":[{"text":"Paces, James B. 0000-0002-9809-8493 jbpaces@usgs.gov","orcid":"https://orcid.org/0000-0002-9809-8493","contributorId":2514,"corporation":false,"usgs":true,"family":"Paces","given":"James","email":"jbpaces@usgs.gov","middleInitial":"B.","affiliations":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"preferred":true,"id":484964,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Nichols, Paul J.","contributorId":87057,"corporation":false,"usgs":true,"family":"Nichols","given":"Paul","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":484966,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Neymark, Leonid A. lneymark@usgs.gov","contributorId":532,"corporation":false,"usgs":true,"family":"Neymark","given":"Leonid","email":"lneymark@usgs.gov","middleInitial":"A.","affiliations":[{"id":218,"text":"Denver Federal Center","active":false,"usgs":true}],"preferred":false,"id":484963,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Rajaram, Harihar","contributorId":61328,"corporation":false,"usgs":true,"family":"Rajaram","given":"Harihar","affiliations":[],"preferred":false,"id":484965,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

In an effort to reduce offshore contamination, a filtering barrier (FB) was installed at Calumet Beach, Lake Michigan, Chicago, IL. A horseshoe-shaped curtain (146 m long, 0.18 mm apparent opening size, 1.5–1.6 m deepest point) was designed to exclude FIB containing or promoting debris and thus reduce the number of swimming advisories during the examination period of July through September 2012. Mean water Escherichia coli concentrations were significantly lower at southern transects (S; outside FB) than at transects within the FB (WN) and at northern transects (N; outside FB) (1.45 log (MPN)/100 ml vs. 1.74 and 1.72, respectively, p < 0.05, n = 234). Turbidity was significantly higher at the WN transects (p < 0.001, n = 233), but it tended to increase throughout the sampling season within and outside the FB. E. coli in adjacent foreshore sand was significantly lower at the WN transects. A combination of factors might explain higher E. coli and turbidity within the FB including increased sediment resuspension, trapped algae, shallowing within the FB, and large lake hydrodynamic processes. This remediation approach may find better use in a different hydrodynamic setting, but the results of this experiment provide insight on sources of contamination and nearshore dynamics that may direct future beach management strategies.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Environmental Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.jenvman.2013.08.040","usgsCitation":"Przybyla-Kelly, K., Nevers, M., Breitenbach, C., and Whitman, R.L., 2013, Recreational water quality response to a filtering barrier at a Great Lakes beach: Journal of Environmental Management, v. 129, p. 635-641, https://doi.org/10.1016/j.jenvman.2013.08.040.","productDescription":"7 p.","startPage":"635","endPage":"641","ipdsId":"IP-049152","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":278296,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":278295,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.jenvman.2013.08.040"}],"country":"United States","state":"Illinois","city":"Chicago","otherGeospatial":"Calumet Beach;Lake Michigan","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -87.529029,41.712252 ], [ -87.529029,41.715995 ], [ -87.526324,41.715995 ], [ -87.526324,41.712252 ], [ -87.529029,41.712252 ] ] ] } } ] }","volume":"129","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"52663ee7e4b0992695a7f446","contributors":{"authors":[{"text":"Przybyla-Kelly, Kasia","contributorId":79004,"corporation":false,"usgs":true,"family":"Przybyla-Kelly","given":"Kasia","affiliations":[],"preferred":false,"id":485025,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Nevers, Meredith 0000-0001-6963-6734 mnevers@usgs.gov","orcid":"https://orcid.org/0000-0001-6963-6734","contributorId":2013,"corporation":false,"usgs":true,"family":"Nevers","given":"Meredith","email":"mnevers@usgs.gov","affiliations":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"preferred":true,"id":485023,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Breitenbach, Cathy","contributorId":55731,"corporation":false,"usgs":true,"family":"Breitenbach","given":"Cathy","affiliations":[],"preferred":false,"id":485024,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Whitman, Richard L. rwhitman@usgs.gov","contributorId":542,"corporation":false,"usgs":true,"family":"Whitman","given":"Richard","email":"rwhitman@usgs.gov","middleInitial":"L.","affiliations":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"preferred":true,"id":485022,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Riparian and in-channel vegetation functions as a roughness element and dissipates flow energy, maintaining stable channel geometry. Ash Creek, a tributary of the Bad River in western South Dakota contains a high proportion of incised channels, remnants of historically high grazing pressure. Best management practices (BMP), including off-stream watering sources and cross fencing, were implemented throughout the Bad River watershed during an Environmental Protection Agency (EPA) 319 effort to address high sediment loads. We monitored prairie cordgrass (Spartina pectinata Link) establishment within stream channels for 16 yr following BMP implementation. Photos were used to group stream reaches (n = 103) subjectively into three classes; absent (estimated < 5% cover; n = 64), present (estimated 5–40% cover; n = 23), and dense (estimated > 40% cover; n = 16) based on the relative amount of prairie cordgrass during 2010 assessments of ephemeral channels. Reaches containing drainage areas of 0.54 to 692 ha were delineated with the use of 2010 National Agriculture Imagery Program (NAIP) imagery. Normalized difference vegetation index (NDVI) values were extracted from 5 to 39 sample points proportional to reach length using a series of Satellite Pour l'Observation de la Terre (SPOT) satellite imagery. Normalized NDVI (nNDVI) of 2 152 sample points were determined from pre- and post-BMP images. Mean nNDVI values for each reach ranged from 0.33 to 1.77. ANOVA revealed significant increase in nNDVI in locations classified as present prairie cordgrass cover following BMP implementation. Establishment of prairie cordgrass following BMP implementation was successfully detected remotely. Riparian vegetation such as prairie cordgrass adds channel roughness that reduces the flow energy responsible for channel degradation.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Rangeland Ecology and Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Society for Range Management","doi":"10.2111/REM-D-11-00153.1","usgsCitation":"Kamp, K.V., Rigge, M.B., Troelstrup, N.H., Smart, A.J., and Wylie, B., 2013, Detecting channel riparian vegetation response to best-management-practices implementation in ephemeral streams with the use of spot high-resolution visible imagery: Rangeland Ecology and Management, v. 66, no. 1, p. 63-70, https://doi.org/10.2111/REM-D-11-00153.1.","productDescription":"8 p.","startPage":"63","endPage":"70","ipdsId":"IP-031895","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":473481,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"http://hdl.handle.net/10150/642688","text":"External Repository"},{"id":278294,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":278293,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2111/REM-D-11-00153.1"}],"country":"United States","state":"South Dakota","otherGeospatial":"Ash Creek","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -100.625496,44.2689280 ], [ -100.625496,44.3229880 ], [ -100.535202,44.3229880 ], [ -100.535202,44.2689280 ], [ -100.625496,44.2689280 ] ] ] } } ] }","volume":"66","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"52663ee5e4b0992695a7f43d","contributors":{"authors":[{"text":"Kamp, Kendall Vande","contributorId":17525,"corporation":false,"usgs":true,"family":"Kamp","given":"Kendall","email":"","middleInitial":"Vande","affiliations":[],"preferred":false,"id":484989,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Rigge, Matthew B. 0000-0003-4471-8009 mrigge@usgs.gov","orcid":"https://orcid.org/0000-0003-4471-8009","contributorId":751,"corporation":false,"usgs":true,"family":"Rigge","given":"Matthew","email":"mrigge@usgs.gov","middleInitial":"B.","affiliations":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true},{"id":223,"text":"Earth Resources Observation and Science (EROS) Center (Geography)","active":false,"usgs":true}],"preferred":true,"id":484986,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Troelstrup, Nels H.

About 70,000 metric tons of SNF are now in pool or dry cask storage at 75 sites across the United States [Government Accountability Office, 2012], and uncertainty about its fate is hobbling future development of nuclear power, increasing costs for utilities, and creating a liability for American taxpayers [Blue Ribbon Commission on America’s Nuclear Future, 2012].However, abandoning Yucca Mountain could also result in broadening geologic options for hosting America’s nuclear waste. Shales and other argillaceous formations (mudrocks, clays, and similar clay-rich media) have been absent from the U.S. repository program. In contrast, France, Switzerland, and Belgium are now planning repositories in argillaceous formations after extensive research in underground laboratories on the safety and feasibility of such an approach [Blue Ribbon Commission on America’s Nuclear Future, 2012; Nationale Genossenschaft für die Lagerung radioaktiver Abfälle (NAGRA), 2010; Organisme national des déchets radioactifs et des matières fissiles enrichies, 2011].

Despite this critical information, which can be garnered through studying the surficial physical expression of a deposit, the geologic and geomorphic sciences have been largely overlooked in artisanal mining-related research. This study demonstrates that a correlation exists between the roles of female miners at artisanal diamond and gold mining sites in western and central Africa and the physical expression of the deposits. Typically, women perform ore processing and ancillary roles at mine sites. On occasion, however, women participate in the extraction process itself. Women were found to participate in the extraction of ore only when a deposit had a thin overburden layer, thus rendering the mineralized ore more accessible. When deposits required a significant degree of manual labour to access the ore due to thick overburden layers, women were typically relegated to other roles. The identification of this link encourages the establishment of an alternative research avenue in which the physical and social sciences merge to better inform policymakers, so that the most appropriate artisanal mining assistance programs can be developed and implemented.","language":"English","publisher":"Wiley","doi":"10.1111/1477-8947.12009","usgsCitation":"Malpeli, K., and Chirico, P., 2013, The influence of geomorphology on the role of women at artisanal and small-scale mine sites: Natural Resources Forum, v. 37, no. 1, p. 43-54, https://doi.org/10.1111/1477-8947.12009.","productDescription":"12 p.","startPage":"43","endPage":"54","ipdsId":"IP-042872","costCenters":[{"id":243,"text":"Eastern Geology and Paleoclimate Science Center","active":true,"usgs":true}],"links":[{"id":278581,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":278580,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/1477-8947.12009"}],"country":"Central African Republic, Ghana, Guinea, Mali","volume":"37","issue":"1","noUsgsAuthors":false,"publicationDate":"2013-04-09","publicationStatus":"PW","scienceBaseUri":"52722aa0e4b0ce70249c9951","contributors":{"authors":[{"text":"Malpeli, Katherine C.","contributorId":55106,"corporation":false,"usgs":true,"family":"Malpeli","given":"Katherine C.","affiliations":[],"preferred":false,"id":485182,"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":485181,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

This study evaluated the coupled continuum pipe-flow framework for modeling karst groundwater flow in the Madison aquifer of western South Dakota (USA). Coupled conduit and matrix flow was simulated within a regional finite-difference model over a 10-year transient period. An existing equivalent porous medium (EPM) model was modified to include major conduit networks whose locations were constrained by dye-tracing data and environmental tracer analysis. Model calibration data included measured hydraulic heads at observation wells and estimates of discharge at four karst springs. Relative to the EPM model, the match to observation well hydraulic heads was substantially improved with the addition of conduits. The inclusion of conduit flow allowed for a simpler hydraulic conductivity distribution in the matrix continuum. Two of the high-conductivity zones in the EPM model, which were required to indirectly simulate the effects of conduits, were eliminated from the new model. This work demonstrates the utility of the coupled continuum pipe-flow method and illustrates how karst aquifer model parameterization is dependent on the physical processes that are simulated.","language":"English","publisher":"Springer","doi":"10.1007/s10040-013-1036-6","usgsCitation":"Saller, S.P., Ronayne, M.J., and Long, A.J., 2013, Comparison of a karst groundwater model with and without discrete conduit flow: Hydrogeology Journal, v. 21, no. 7, p. 1555-1566, https://doi.org/10.1007/s10040-013-1036-6.","productDescription":"12 p.","startPage":"1555","endPage":"1566","ipdsId":"IP-042678","costCenters":[{"id":562,"text":"South Dakota Water Science Center","active":true,"usgs":true},{"id":34685,"text":"Dakota Water Science Center","active":true,"usgs":true}],"links":[{"id":278287,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"South Dakota","otherGeospatial":"Madison Aquifer","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -104.06,42.48 ], [ -104.06,45.95 ], [ -101.86,45.95 ], [ -101.86,42.48 ], [ -104.06,42.48 ] ] ] } } ] }","volume":"21","issue":"7","noUsgsAuthors":false,"publicationDate":"2013-09-06","publicationStatus":"PW","scienceBaseUri":"52624a53e4b079a99629a0d3","contributors":{"authors":[{"text":"Saller, Stephen P.","contributorId":60118,"corporation":false,"usgs":true,"family":"Saller","given":"Stephen","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":484911,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Ronayne, Michael J.","contributorId":101556,"corporation":false,"usgs":true,"family":"Ronayne","given":"Michael","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":484912,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Long, Andrew J. 0000-0001-7385-8081 ajlong@usgs.gov","orcid":"https://orcid.org/0000-0001-7385-8081","contributorId":989,"corporation":false,"usgs":true,"family":"Long","given":"Andrew","email":"ajlong@usgs.gov","middleInitial":"J.","affiliations":[{"id":622,"text":"Washington Water Science Center","active":true,"usgs":true},{"id":562,"text":"South Dakota Water Science Center","active":true,"usgs":true}],"preferred":true,"id":484910,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Natural spawning is known to occur at several locations in the Kootenai River, Idaho, but there is little natural recruitment. Microhabitat where embryo incubation occurs is known to be an important factor in white sturgeon reproductive success. This study was conducted to address questions regarding the suitability of different substrates as egg attachment and incubation sites for these fish. A comparative laboratory study using six types of incubation substrates—clean river rocks, periphyton- and algae-covered rocks, waterlogged wood, sand, riparian vegetation, and clean glass plates—tested the hypothesis that survival to hatch of white sturgeon eggs differs among incubation substrates. The results showed that sand was unsuitable as an incubation substrate, as the adhesive embryos were easily dislodged. Periphyton- and algae-covered rocks had the lowest hatch success, and all other substrates had similar hatch success.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/sir20135180","collaboration":"Prepared in cooperation with the Kootenai Tribe of Idaho","usgsCitation":"Parsley, M.J., and Kofoot, E., 2013, Effects of incubation substrates on hatch timing and success of White Sturgeon (<i>Acipenser transmontanus</i>) embryos: U.S. Geological Survey Scientific Investigations Report 2013-5180, 16 p., https://doi.org/10.3133/sir20135180.","productDescription":"16 p.","numberOfPages":"24","costCenters":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"links":[{"id":278286,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/sir20135180.jpg"},{"id":278284,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/sir/2013/5180/"},{"id":278285,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/sir/2013/5180/pdf/sir2013-5180.pdf"}],"country":"United States","state":"Idaho","otherGeospatial":"Kootenai River","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -116.540609,48.360962 ], [ -116.540609,48.999704 ], [ -115.314595,48.999704 ], [ -115.314595,48.360962 ], [ -116.540609,48.360962 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"52624a65e4b079a99629a0d6","contributors":{"authors":[{"text":"Parsley, Michael J. 0000-0003-0097-6364 mparsley@usgs.gov","orcid":"https://orcid.org/0000-0003-0097-6364","contributorId":2608,"corporation":false,"usgs":true,"family":"Parsley","given":"Michael","email":"mparsley@usgs.gov","middleInitial":"J.","affiliations":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"preferred":true,"id":485001,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kofoot, Eric","contributorId":9939,"corporation":false,"usgs":true,"family":"Kofoot","given":"Eric","affiliations":[],"preferred":false,"id":485002,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Unlike the mule deer, whose existence has been established by generations of biologists, wildlife management professionals, and sportsmen, Le Raye and his journal have since been proven to be fraudulent. Because Rafinesque's names were published in accordance with the taxonomic conventions of his time, they remain available, but, based on the questionable source of his descriptions, the identities and type localities of the species must be viewed as unreliable. Fortunately, much of the Le Raye journal was derived from other, verifiable contemporary sources. In particular, the descriptions of the two deer were based on the published journal of Patrick Gass, a member of the Lewis and Clark Expedition.

We seek to identify whether discrete or diffuse groundwater inflow is the dominant control on refugia. Numerous springs and seeps were identified at all locations where dwarf wedgemussels still can be found.  Infrared imagery and custom high spatial resolution fiber-optic distributed temperature sensors reveal complex thermal dynamics at one of the seeps with a relatively stable, cold groundwater plume extending along the streambed/water-column interface during mid-summer.  This plume, primarily fed by a discrete bank seep, was shown through analytical and numerical heat-transport modeling to dominate temperature dynamics in the region of potential habitation by the adult dwarf wedgemussel.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Science and Technology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"American Chemical Society","doi":"10.1021/es4018893","usgsCitation":"Briggs, M., Voytek, E.B., Day-Lewis, F.D., Rosenberry, D.O., and Lane, J.W., 2013, Understanding water column and streambed thermal refugia for endangered mussels in the Delaware River: Environmental Science & Technology, v. 47, no. 20, p. 11423-11431, https://doi.org/10.1021/es4018893.","productDescription":"9 p.","startPage":"11423","endPage":"11431","ipdsId":"IP-050356","costCenters":[{"id":486,"text":"OGW Branch of Geophysics","active":true,"usgs":true}],"links":[{"id":278271,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":278240,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1021/es4018893"},{"id":278241,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.acs.org/doi/pdf/10.1021/es4018893"}],"country":"United States","state":"Pennsylvania","otherGeospatial":"Delaware River","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -75.243,41.836 ], [ -75.243,41.876 ], [ -75.204,41.876 ], [ -75.204,41.836 ], [ -75.243,41.836 ] ] ] } } ] }","volume":"47","issue":"20","noUsgsAuthors":false,"publicationDate":"2013-09-25","publicationStatus":"PW","scienceBaseUri":"52624a6be4b079a99629a0f1","contributors":{"authors":[{"text":"Briggs, Martin A.","contributorId":10321,"corporation":false,"usgs":true,"family":"Briggs","given":"Martin A.","affiliations":[],"preferred":false,"id":484909,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Voytek, Emily B. 0000-0003-0981-453X ebvoytek@usgs.gov","orcid":"https://orcid.org/0000-0003-0981-453X","contributorId":3575,"corporation":false,"usgs":true,"family":"Voytek","given":"Emily","email":"ebvoytek@usgs.gov","middleInitial":"B.","affiliations":[{"id":486,"text":"OGW Branch of Geophysics","active":true,"usgs":true}],"preferred":true,"id":484908,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Day-Lewis, Frederick D. 0000-0003-3526-886X daylewis@usgs.gov","orcid":"https://orcid.org/0000-0003-3526-886X","contributorId":1672,"corporation":false,"usgs":true,"family":"Day-Lewis","given":"Frederick","email":"daylewis@usgs.gov","middleInitial":"D.","affiliations":[{"id":486,"text":"OGW Branch of Geophysics","active":true,"usgs":true},{"id":493,"text":"Office of Ground Water","active":true,"usgs":true},{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true}],"preferred":true,"id":484906,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Rosenberry, Donald O. 0000-0003-0681-5641 rosenber@usgs.gov","orcid":"https://orcid.org/0000-0003-0681-5641","contributorId":1312,"corporation":false,"usgs":true,"family":"Rosenberry","given":"Donald","email":"rosenber@usgs.gov","middleInitial":"O.","affiliations":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true},{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true}],"preferred":true,"id":484905,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Lane, John W.

On the basis of sampling and analyses of the top 1–2 centimeters (cm) of available cores, three main belts of sediments were identified on each transect with increasing depth: (1) muds rich in organic carbon (OC); (2) authigenic phosphatic mineral crusts and pavements; and (3) glaucony facies.</p><p>Sediments rich in OC on the 12°S transect were mainly located on the outer shelf and upper slope (150–350 m), but they occurred in much shallower water (approximately 100 m) on the 13.5°S transect. The organic matter is almost entirely marine as confirmed by Rock-Eval pyrolysis and isotopic composition of OC. Concentrations of OC are highest (up to 18 percent) in sediments within the OMZ where dissolved oxygen (DO) concentrations are &lt;5 micromoles per kilogram (μM). Even at these low concentrations of DO, however, the surface sediments from within the OMZ are dominantly unlaminated. Concentrations of DO may have the dominant effect on organic matter characteristics, but reworking of fine-grained sediment and organic matter by strong bottom currents with velocities as high as 30 centimeters per second (cm/s) on the slope between 150 and 300 m and redeposition on the seafloor in areas of lower energy and higher DO concentration also exert important controls on OC concentration and degree of oxidation in this region.</p><p>Phosphate-rich sediments and crusts occurred at depths of about 300 to 550 m on both transects. Nodular crusts of sediment cemented by carbonate-fluorapatite (CFA; phosphorite) or dolomite form within the OMZ. These phosphorite crusts evolve through cementation from light olive-green, stiff but friable, phosphatized claystone “protocrusts” through dense, dark phosphorite crusts, cemented breccias, and pavements. The degree of phosphatization and thickness of the crusts depend on the rates of sediment supply and on the strength and frequency of currents that re-expose crusts on the seafloor. Phosphorite crusts and pavements on the Peru margin can only become buried and incorporated into the geologic record once bottom currents slacken sufficiently to allow fine-grained sediment to accumulate.</p><p>Glaucony-rich surface sediments, relatively undiluted by other components, were found mainly in deeper water on the 13.5°S transect (750 m to at least 1,067 m). These sediments consist almost entirely of sand-size glaucony pellets. These widespread glaucony sands formed in place and were then concentrated and reworked by strong currents that winnowed away the fine-grained matrix. Although the glaucony occurs in sand-size pellets, the pellets are made up of aggregates of authigenic, platy, micaceous clay minerals. Glaucony is predominantly a potassium (K), sodium (Na), iron (Fe), magnesium (Mg) aluminosilicate with an approximate formula of (K,Na)(Fe<sup>3+</sup>,Al,Mg)<sub>2</sub>(Si,Al)<sub>4</sub>O<sub>10</sub>(OH)<sub>2</sub>. The glaucony on the 13.5°S transect forms by alteration of one or more original “framework” minerals (carbonate and [or] aluminosilicates) to form pellital aggregates of Fe-, K-, and Mg-rich clay minerals. Because Fe, K, and Mg are derived from seawater, sedimentation rates must be extremely slow in order for the original framework minerals to remain in contact with seawater. The close association of glaucony and phosphorite indicates a delicate balance between the slightly oxidizing conditions at the base of the OMZ that form glaucony and the slightly reducing conditions that mobilize iron and phosphate to form phosphorite.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr20131105","usgsCitation":"Arthur, M.A., and Dean, W.E., 2013, Oceanographic controls on sedimentary and geochemical facies on the Peru outer shelf and upper slope: U.S. Geological Survey Open-File Report 2013-1105, v, 38 p., https://doi.org/10.3133/ofr20131105.","productDescription":"v, 38 p.","numberOfPages":"43","onlineOnly":"Y","ipdsId":"IP-037568","costCenters":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"links":[{"id":278263,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr20131105.gif"},{"id":278243,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2013/1105/"},{"id":278262,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2013/1105/pdf/OF13-1105.pdf"}],"country":"Peru","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -81,-14 ], [ -81,-10 ], [ -74,-10 ], [ -74,-14 ], [ -81,-14 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"52624a68e4b079a99629a0e8","contributors":{"authors":[{"text":"Arthur, Michael A.","contributorId":90018,"corporation":false,"usgs":true,"family":"Arthur","given":"Michael","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":484953,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Dean, Walter E. dean@usgs.gov","contributorId":1801,"corporation":false,"usgs":true,"family":"Dean","given":"Walter","email":"dean@usgs.gov","middleInitial":"E.","affiliations":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"preferred":true,"id":484952,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The map area contains the westernmost portion of the Columbia River Gorge National Scenic area as well as the rapidly growing areas surrounding the Clark County, Washington, cities of Camas and Washougal. The Columbia River transects the map area, and two major tributaries, the Washougal River in Washington and the Sandy River in Oregon, also flow through the quadrangle. The Columbia, Washougal, and Sandy Rivers have all cut deep valleys through hilly uplands, exposing Oligocene volcanic bedrock in the north part of the map area and lava flows of the Miocene Columbia River Basalt Group in the western Columbia River Gorge. Elsewhere in the map area, these older rocks are buried beneath weakly consolidated to well-consolidated Neogene and younger basin-fill sedimentary rocks and Quaternary volcanic and sedimentary deposits. The Portland Basin is part of the Coastal Lowland that separates the Cascade Range from the Oregon Coast Range. The basin has been interpreted as a pull-apart basin located in the releasing stepover between two en echelon, northwest-striking, right-lateral fault zones. These fault zones are thought to reflect regional transpression, transtension, and dextral shear within the forearc in response to oblique subduction of the Pacific plate along the Cascadia Subduction Zone. The southwestern margin of the Portland Basin is a well-defined topographic break along the base of the Tualatin Mountains, an asymmetric anticlinal ridge that is bounded on its northeast flank by the Portland Hills Fault Zone, which is probably an active structure. The nature of the corresponding northeastern margin of the basin is less clear, but a series of poorly defined and partially buried dextral extensional structures has been hypothesized from topography, microseismicity, potential-field anomalies, and reconnaissance geologic mapping. This map is a contribution to a program designed to improve the geologic database for the Portland Basin region of the Pacific Northwest urban corridor, the densely populated Cascadia forearc region of western Washington and Oregon. Updated, more detailed information on the bedrock and surficial geology of the basin and its surrounding area will facilitate improved assessments of seismic risk, and resource availability in this rapidly growing region.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/sim3257","usgsCitation":"Evarts, R.C., O'Connor, J., and Tolan, T.L., 2013, Geologic map of the Washougal quadrangle, Clark County, Washington, and Multnomah County, Oregon: U.S. Geological Survey Scientific Investigations Map 3257, Pamphlet: iii, 46 p.; 1 Plate: 54.84 x 36.00 inches; Metadata; Readme, https://doi.org/10.3133/sim3257.","productDescription":"Pamphlet: iii, 46 p.; 1 Plate: 54.84 x 36.00 inches; Metadata; Readme","numberOfPages":"49","onlineOnly":"N","additionalOnlineFiles":"Y","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true},{"id":615,"text":"Volcano Hazards Program","active":true,"usgs":true}],"links":[{"id":398883,"rank":8,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_99068.htm","linkFileType":{"id":5,"text":"html"}},{"id":278248,"rank":5,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/sim/3257/pdf/sim3257_map.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":278250,"rank":4,"type":{"id":16,"text":"Metadata"},"url":"https://pubs.usgs.gov/sim/3257/downloads/washougal_metadata.txt","linkFileType":{"id":1,"text":"pdf"}},{"id":278247,"rank":3,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/sim/3257/pdf/sim3257_pamphlet.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":278249,"rank":6,"type":{"id":20,"text":"Read Me"},"url":"https://pubs.usgs.gov/sim/3257/pdf/washougal_readme.pdf"},{"id":278251,"rank":1,"type":{"id":7,"text":"Companion Files"},"url":"https://pubs.usgs.gov/sim/3257/downloads/sim3257_db.zip"},{"id":278252,"rank":2,"type":{"id":7,"text":"Companion Files"},"url":"https://pubs.usgs.gov/sim/3257/downloads/sim3257_shp.zip"},{"id":278253,"rank":7,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/sim3257.gif"}],"scale":"24000","country":"United States","state":"Oregon","county":"Clark County, Multnomah County","otherGeospatial":"Washougal quadrangle","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -122.375,\n              45.5\n            ],\n            [\n              -122.25,\n              45.5\n            ],\n            [\n              -122.25,\n              45.625\n            ],\n            [\n              -122.375,\n              45.625\n            ],\n            [\n              -122.375,\n              45.5\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"52624a67e4b079a99629a0e2","contributors":{"authors":[{"text":"Evarts, Russell C. revarts@usgs.gov","contributorId":1974,"corporation":false,"usgs":true,"family":"Evarts","given":"Russell","email":"revarts@usgs.gov","middleInitial":"C.","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":484973,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"O'Connor, Jim E. 0000-0002-7928-5883 oconnor@usgs.gov","orcid":"https://orcid.org/0000-0002-7928-5883","contributorId":140771,"corporation":false,"usgs":true,"family":"O'Connor","given":"Jim E.","email":"oconnor@usgs.gov","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true},{"id":518,"text":"Oregon Water Science Center","active":true,"usgs":true}],"preferred":false,"id":484975,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Tolan, Terry L.","contributorId":31029,"corporation":false,"usgs":true,"family":"Tolan","given":"Terry","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":484974,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The size of these particles varies widely from less than 2 µm to larger particles that can exceed 50 µm in diameter. In this study, we present two continuous records of total suspended particle (TSP) concentrations at sites in Mesa Verde and Canyonlands National Parks in Colorado and Utah, USA, respectively, and compare those values to measurements of fine and coarse particle concentrations made from nearby samplers. Average annual concentrations of TSP at Mesa Verde were 90 µg m−3 in 2011 and at Canyonlands were 171 µg m<sup>−3</sup> in 2009, 113 µg m<sup>−3</sup> in 2010, and 134 µg m<sup>−3</sup> in 2011. In comparison, annual concentrations of fine (diameter of 2.5 µm and below) and coarse (2.5–10 µm diameter) particles at these sites were below 10 µg m<sup>−3</sup> in all years. The high concentrations of TSP appear to be the result of regional dust storms with elevated concentrations of particles greater than 10 µm in diameter. These conditions regularly occur from spring through fall with 2 week mean TSP periodically in excess of 200 µg m<sup>−3</sup>. Measurement of particles on filters indicates that the median particle size varies between approximately 10 µm in winter and 40 µm during the spring. These persistently elevated concentrations of large particles indicate that regional dust emission as dust storms and events are important determinants of air quality in this region.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Geophysical Research D: Atmospheres","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"American Geophysical Union","doi":"10.1002/jgrd.50855","usgsCitation":"Neff, J.C., Reynolds, R.L., Munson, S.M., Fernandez, D., and Belnap, J., 2013, The role of dust storms in total atmospheric particle concentrations at two sites in the western U.S.: Journal of Geophysical Research D: Atmospheres, v. 118, no. 19, p. 11201-11212, https://doi.org/10.1002/jgrd.50855.","productDescription":"12 p.","startPage":"11201","endPage":"11212","numberOfPages":"12","ipdsId":"IP-051031","costCenters":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"links":[{"id":473483,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1002/jgrd.50855","text":"Publisher Index Page"},{"id":287312,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":287296,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/jgrd.50855"}],"country":"United States","state":"Colorado;Utah","otherGeospatial":"Canyonlands National Park;Mesa Verde National Park","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -114.8166,31.3322 ], [ -114.8166,42.0016 ], [ -102.0409,42.0016 ], [ -102.0409,31.3322 ], [ -114.8166,31.3322 ] ] ] } } ] }","volume":"118","issue":"19","noUsgsAuthors":false,"publicationDate":"2013-10-10","publicationStatus":"PW","scienceBaseUri":"537c7975e4b00e1e1a484896","contributors":{"authors":[{"text":"Neff, Jason C.","contributorId":34813,"corporation":false,"usgs":true,"family":"Neff","given":"Jason","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":493860,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Reynolds, Richard L. 0000-0002-4572-2942 rreynolds@usgs.gov","orcid":"https://orcid.org/0000-0002-4572-2942","contributorId":441,"corporation":false,"usgs":true,"family":"Reynolds","given":"Richard","email":"rreynolds@usgs.gov","middleInitial":"L.","affiliations":[{"id":271,"text":"Federal Center","active":false,"usgs":true}],"preferred":true,"id":493857,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Munson, Seth M. 0000-0002-2736-6374 smunson@usgs.gov","orcid":"https://orcid.org/0000-0002-2736-6374","contributorId":1334,"corporation":false,"usgs":true,"family":"Munson","given":"Seth","email":"smunson@usgs.gov","middleInitial":"M.","affiliations":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true},{"id":411,"text":"National Climate Change and Wildlife Science Center","active":true,"usgs":true}],"preferred":true,"id":493859,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Fernandez, Daniel","contributorId":80588,"corporation":false,"usgs":true,"family":"Fernandez","given":"Daniel","affiliations":[],"preferred":false,"id":493861,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Belnap, Jayne 0000-0001-7471-2279 jayne_belnap@usgs.gov","orcid":"https://orcid.org/0000-0001-7471-2279","contributorId":1332,"corporation":false,"usgs":true,"family":"Belnap","given":"Jayne","email":"jayne_belnap@usgs.gov","affiliations":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"preferred":true,"id":493858,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

The well unexpectedly drilled into a high-silica (76.5 % SiO<sub>2</sub>) rhyolite melt at approximately 2.1 km. Some of the melt vesiculated while extruding into the drill hole, but most of the recovered cuttings are quenched sparsely phyric, vesicle-poor glass. The phenocryst assemblage is comprised of titanomagnetite, plagioclase, augite, and pigeonite. Compositional zoning in plagioclase and exsolution lamellae in augite and pigeonite record changing crystallization conditions as the melt migrated to its present depth of emplacement. The in situ temperature of the melt is estimated to be between 850 and 920 °C based on two-pyroxene geothermometry and modeling of the crystallization sequence. Volatile content of the glass indicated partial degassing at an in situ pressure that is above hydrostatic (~16 MPa) and below lithostatic (~55 MPa). The major element and minor element composition of the melt are consistent with an origin by partial melting of hydrothermally altered basaltic crust at depth, similar to rhyolite erupted within the Krafla Caldera. Chondrite-normalized REE concentrations show strong light REE enrichment and relative flat patterns with negative Eu anomaly. Strontium isotope values (0.70328) are consistent with mantle-derived melt, but oxygen and hydrogen isotope values are depleted (3.1 and −118 ‰, respectively) relative to mantle values. The hydrogen isotope values overlap those of hydrothermal epidote from rocks altered by the meteoric-water-recharged Krafla geothermal system. The rhyolite melt was emplaced into and has reacted with a felsic intrusive suite that has nearly identical composition. The felsite is composed of quartz, alkali feldspar, plagioclase, titanomagnetite, and augite. Emplacement of the rhyolite magma has resulted in partial melting of the felsite, accompanied locally by partial assimilation. The interstitial melt in the felsite has similar normalized SiO<sub>2</sub> content as the rhyolite melt but is distinguished by higher K<sub>2</sub>O and lower CaO and plots near the minimum melt composition in the granite system. Augite in the partially melted felsite has re-equilibrated to more calcic metamorphic compositions. Rare quenched glass fragments containing glomeroporphyritic crystals derived from the felsite show textural evidence for resorption of alkali feldspar and quartz. The glass in these fragments is enriched in SiO<sub>2</sub> relative to the rhyolite melt or the interstitial felsite melt, consistent with the textural evidence for quartz dissolution. The quenching of these melts by drilling fluids at in situ conditions preserves details of the melt–wall rock interaction that would not be readily observed in rocks that had completely crystallized. However, these processes may be recognizable by a combination of textural analysis and in situ analytical techniques that document compositional heterogeneity due to partial melting and local assimilation.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Contributions to Mineralogy and Petrology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer","doi":"10.1007/s00410-012-0811-z","usgsCitation":"Zierenberg, R., Schiffmant, P., Barfod, G., Lesher, C., Marks, N., Lowenstern, J.B., Mortensen, A., Pope, E., Bird, D., Reed, M., Fridleifsson, G., and Elders, W., 2013, Composition and origin of rhyolite melt intersected by drilling in the Krafla geothermal field, Iceland: Contributions to Mineralogy and Petrology, v. 165, no. 2, p. 327-347, https://doi.org/10.1007/s00410-012-0811-z.","productDescription":"21 p.","startPage":"327","endPage":"347","numberOfPages":"21","ipdsId":"IP-041015","costCenters":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":281311,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":281310,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s00410-012-0811-z"}],"country":"Iceland","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -16.857456,65.723445 ], [ -16.857456,65.752183 ], [ -16.807488,65.752183 ], [ -16.807488,65.723445 ], [ -16.857456,65.723445 ] ] ] } } ] }","volume":"165","issue":"2","noUsgsAuthors":false,"publicationDate":"2012-09-22","publicationStatus":"PW","scienceBaseUri":"53cd5243e4b0b290850f46dc","contributors":{"authors":[{"text":"Zierenberg, R.A.","contributorId":8998,"corporation":false,"usgs":true,"family":"Zierenberg","given":"R.A.","email":"","affiliations":[],"preferred":false,"id":488866,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Schiffmant, Peter","contributorId":51016,"corporation":false,"usgs":true,"family":"Schiffmant","given":"Peter","affiliations":[],"preferred":false,"id":488873,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Barfod, G.H.","contributorId":93380,"corporation":false,"usgs":true,"family":"Barfod","given":"G.H.","email":"","affiliations":[],"preferred":false,"id":488875,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Lesher, C.E.","contributorId":28217,"corporation":false,"usgs":true,"family":"Lesher","given":"C.E.","email":"","affiliations":[],"preferred":false,"id":488870,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Marks, N.E.","contributorId":48410,"corporation":false,"usgs":true,"family":"Marks","given":"N.E.","email":"","affiliations":[],"preferred":false,"id":488872,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Lowenstern, Jacob B. 0000-0003-0464-7779 jlwnstrn@usgs.gov","orcid":"https://orcid.org/0000-0003-0464-7779","contributorId":2755,"corporation":false,"usgs":true,"family":"Lowenstern","given":"Jacob","email":"jlwnstrn@usgs.gov","middleInitial":"B.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":488865,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Mortensen, A.K.","contributorId":107526,"corporation":false,"usgs":true,"family":"Mortensen","given":"A.K.","email":"","affiliations":[],"preferred":false,"id":488876,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Pope, E.C.","contributorId":30478,"corporation":false,"usgs":true,"family":"Pope","given":"E.C.","email":"","affiliations":[],"preferred":false,"id":488871,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Bird, D.K.","contributorId":24934,"corporation":false,"usgs":true,"family":"Bird","given":"D.K.","email":"","affiliations":[],"preferred":false,"id":488869,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Reed, M.H.","contributorId":91606,"corporation":false,"usgs":true,"family":"Reed","given":"M.H.","email":"","affiliations":[],"preferred":false,"id":488874,"contributorType":{"id":1,"text":"Authors"},"rank":10},{"text":"Fridleifsson, G.O.","contributorId":17911,"corporation":false,"usgs":true,"family":"Fridleifsson","given":"G.O.","email":"","affiliations":[],"preferred":false,"id":488867,"contributorType":{"id":1,"text":"Authors"},"rank":11},{"text":"Elders, W.A.","contributorId":18110,"corporation":false,"usgs":true,"family":"Elders","given":"W.A.","email":"","affiliations":[],"preferred":false,"id":488868,"contributorType":{"id":1,"text":"Authors"},"rank":12}]}}

In these circumstances spatially explicit capture-recapture (SECR) models, which incorporate the observed locations of individuals, allow population density and abundance to be estimated while accounting for differences in detectability of individuals. In this paper I propose two Bayesian SECR models, one for the analysis of recaptures observed in trapping arrays and another for the analysis of recaptures observed in area searches. In formulating these models I used distinct submodels to specify the distribution of individual home-range centers and the observable recaptures associated with these individuals. This separation of ecological and observational processes allowed me to derive a formal connection between Bayes and empirical Bayes estimators of population abundance that has not been established previously. I showed that this connection applies to every Poisson point-process model of SECR data and provides theoretical support for a previously proposed estimator of abundance based on recaptures in trapping arrays. To illustrate results of both classical and Bayesian methods of analysis, I compared Bayes and empirical Bayes esimates of abundance and density using recaptures from simulated and real populations of animals. Real populations included two iconic datasets: recaptures of tigers detected in camera-trap surveys and recaptures of lizards detected in area-search surveys. In the datasets I analyzed, classical and Bayesian methods provided similar – and often identical – inferences, which is not surprising given the sample sizes and the noninformative priors used in the analyses.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"PLoS ONE","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"PLoS ONE","doi":"10.1371/journal.pone.0084017","usgsCitation":"Dorazio, R.M., 2013, Bayes and empirical Bayes estimators of abundance and density from spatial capture-recapture data: PLoS ONE, v. 8, no. 12, 12 p., https://doi.org/10.1371/journal.pone.0084017.","productDescription":"12 p.","ipdsId":"IP-044554","costCenters":[{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true}],"links":[{"id":473484,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1371/journal.pone.0084017","text":"Publisher Index Page"},{"id":281302,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":281301,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1371/journal.pone.0084017"}],"volume":"8","issue":"12","noUsgsAuthors":false,"publicationDate":"2013-12-27","publicationStatus":"PW","scienceBaseUri":"53cd4efae4b0b290850f26cb","contributors":{"authors":[{"text":"Dorazio, Robert M. 0000-0003-2663-0468 bob_dorazio@usgs.gov","orcid":"https://orcid.org/0000-0003-2663-0468","contributorId":1668,"corporation":false,"usgs":true,"family":"Dorazio","given":"Robert","email":"bob_dorazio@usgs.gov","middleInitial":"M.","affiliations":[{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true}],"preferred":false,"id":488864,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Presently, ∼1700 small glaciers and ice masses near the crest of the range occur above 3250 m in elevation; these covered an area of ∼50 km<sup>2</sup><span>&nbsp;</span>in 1972. Fourteen of the largest glaciers decreased by about one half in area during the period from 1900 to 2004.</p><p>Rock glaciers, generally glacial ice covered by 1–10 m of rockfall debris, occur in about the same span of the range as ice and permanent snowfields. They are, on average, lower by 200–300 m, apparently because of the insulating layer of rocky rubble that protects their internal ice from the sun’s heat and from wind.</p><p>The principal Pleistocene glacial stages are the Sherwin (ca. 820 ka), Tahoe (170–130 and ca. 70 ka), Tioga (14–28 ka), and Recess Peak (13 ka). Some 7040 glacial lakes, produced primarily by quarrying from bedrock, were mostly exposed after recession of the Tioga glacial stage. The lakes largely mark the area of primary snow accumulation. Below the lower limit of the lakes, ice flowed downward into river-cut canyons, forming major trunk glaciers within the zone of ablation.</p><p>The range is in general a westward-tilted block upfaulted on its east side. Therefore, the main late Pleistocene trunk glaciers (Tahoe/Tioga) west of the crest extend 25–60 km, whereas those east of the crest extend only 5–20 km. Because of higher precipitation northward, glacial features such as the toes of existing glaciers and rock glaciers, as well as the late season present-day snowline, all decrease in elevation northward. Likewise, the elevation of the lower limit of glacial lakes, an indication of the zone of snow accumulation during the late Pleistocene, decreases about the same degree. This similarity suggests that the overall climate patterns of the late Pleistocene, though cooler, were similar to those of today. The east slope glaciers show a similar northward depression, but they are ∼500–1000 m higher.</p><p>The upper part of the glacial system was erosive over a broad highland area as the evenly distributed ice in the accumulation zone moved to lower elevation. The abundant lake basins record this erosive action. The lower part of the glacier system was largely confined to major preexisting river canyons in which melting dominated. The average of rangewide estimates of the equilibrium line altitude (ELA)—the boundary between the upper snow and ice accumulation zone and the lower ablation zone—of many late Pleistocene glaciers parallels, and is only 200–300 m above, the altitude of the lower limit of the lakes.

In addition to reducing the risk of high-severity wildfires in unwanted areas, stand thinning may increase wildlife and plant diversity and provide increased opportunity for seedling recruitment. We initiated conservative (i.e. minimal removal of trees) ponderosa stand thinning treatments with the goals of reducing fire risk and improving habitat conditions for native wildlife and flora. We then compared site occupancy of brown-headed cowbirds (</span><i>Molothrus ater</i><span>), chipping sparrows (</span><i>Spizella passerina</i><span>), plumbeous vireos (</span><i>Vireo plumbeus</i><span>), and western wood-pewees (</span><i>Contopus sordidulus</i><span>) in thinned and unthinned (i.e., control) forest stands from 2007 to 2009. Survey stations located in thinned stands had 64% fewer trees/ha, 25% less canopy cover, and 23% less basal area than stations in control stands. Occupancy by all three host species was negatively associated with tree density, suggesting that these species respond favorably to forest thinning treatments in ponderosa pine forests. We also encountered plumbeous vireos more frequently in plots closer to an ecotonal (forest/grassland) edge, an association that may increase their susceptibility to edge-specialist, brood parasites like brown-headed cowbirds. Occupancy of brown-headed cowbirds was not related to forest metrics but was related to occupancy by plumbeous vireos and the other host species in aggregate, supporting previous reports on the affiliation between these species. Forest management practices that promote heterogeneity in forest stand structure may benefit songbird populations in our area, but these treatments may also confer costs associated with increased cowbird occupancy. Further research is required to understand more on the complex relationships between occupancy of cowbirds and host species, and between cowbird occupancy and realized rates of nest parasitism.</span></p>","language":"English","publisher":"Elsevier","publisherLocation":"New York, NY","doi":"10.1016/j.foreco.2013.06.037","usgsCitation":"Keeley, W., Germaine, S., Stanley, T.R., Spaulding, S.A., and Wanner, C., 2013, Response of brown-headed cowbirds and three host species to thinning treatments in low-elevation ponderosa pine forests along the northern Colorado Front Range: Forest Ecology and Management, v. 306, p. 226-233, https://doi.org/10.1016/j.foreco.2013.06.037.","productDescription":"8 p.","startPage":"226","endPage":"233","numberOfPages":"8","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-056818","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":309371,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Colorado","county":"Boulder County","volume":"306","publishingServiceCenter":{"id":2,"text":"Denver PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"560d07bae4b058f706e54312","contributors":{"authors":[{"text":"Keeley, W.H.","contributorId":147663,"corporation":false,"usgs":false,"family":"Keeley","given":"W.H.","email":"","affiliations":[{"id":590,"text":"U.S. Army Corps of Engineers","active":false,"usgs":false}],"preferred":false,"id":572269,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Germaine, Steve 0000-0002-7614-2676 germaines@usgs.gov","orcid":"https://orcid.org/0000-0002-7614-2676","contributorId":4743,"corporation":false,"usgs":true,"family":"Germaine","given":"Steve","email":"germaines@usgs.gov","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":false,"id":572268,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Stanley, Thomas R. 0000-0002-8393-0005 stanleyt@usgs.gov","orcid":"https://orcid.org/0000-0002-8393-0005","contributorId":209928,"corporation":false,"usgs":true,"family":"Stanley","given":"Thomas","email":"stanleyt@usgs.gov","middleInitial":"R.","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":true,"id":572270,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Spaulding, Sarah A. 0000-0002-9787-7743 sspaulding@usgs.gov","orcid":"https://orcid.org/0000-0002-9787-7743","contributorId":1157,"corporation":false,"usgs":true,"family":"Spaulding","given":"Sarah","email":"sspaulding@usgs.gov","middleInitial":"A.","affiliations":[{"id":451,"text":"National Water Quality Assessment Program","active":true,"usgs":true}],"preferred":true,"id":572271,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Wanner, C.E.","contributorId":147664,"corporation":false,"usgs":false,"family":"Wanner","given":"C.E.","email":"","affiliations":[{"id":590,"text":"U.S. Army Corps of Engineers","active":false,"usgs":false}],"preferred":false,"id":572272,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Resilience is the measure of disturbance an ecological system can absorb before changing states. However, how the intrinsic structures and processes of systems that characterize their states affects their resilience remains unclear. We analyzed time series of phytoplankton communities at three sites in a floodplain in central Spain to assess the dominant frequencies or &ldquo;temporal scales&rdquo; in community dynamics and compared the patterns between a wet and a dry alternative state. The identified frequencies and cross-scale structures are expected to arise from positive feedbacks that are thought to reinforce processes in alternative states of ecological systems and regulate emergent phenomena such as resilience. Our analyses show a higher species richness and diversity but lower evenness in the dry state. Time series modeling revealed a decrease in the importance of short-term variability in the communities, suggesting that community dynamics slowed down in the dry relative to the wet state. The number of temporal scales at which community dynamics manifested, and the explanatory power of time series models, was lower in the dry state. The higher diversity, reduced number of temporal scales and the lower explanatory power of time series models suggest that species dynamics tended to be more stochastic in the dry state. From a resilience perspective our results highlight a paradox: increasing species richness may not necessarily enhance resilience. The loss of cross-scale structure (i.e. the lower number of temporal scales) in community dynamics across sites suggests that resilience erodes during drought. Phytoplankton communities in the dry state are therefore likely less resilient than in the wet state. Our case study demonstrates the potential of time series modeling to assess attributes that mediate resilience. The approach is useful for assessing resilience of alternative states across ecological and other complex systems.</p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"PLoS One","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Public Library of Science","publisherLocation":"San Francisco","doi":"10.1371/journal.pone.0077338","usgsCitation":"Angeler, D., Allen, C.R., Rojo, C., Alvarez-Cobelas, M., Rodrigo, M.A., and Sanchez-Carrillo, S., 2013, Inferring the relative resilience of alternative states: PLoS ONE, v. 8, no. 10, e77338, https://doi.org/10.1371/journal.pone.0077338.","productDescription":"e77338","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-051609","costCenters":[{"id":200,"text":"Coop Res Unit Seattle","active":true,"usgs":true}],"links":[{"id":473486,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1371/journal.pone.0077338","text":"Publisher Index Page"},{"id":318032,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Spain","otherGeospatial":"Las Tablas de Daimiel floodplain wetland","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -3.2299804687499996,\n              41.73852846935917\n            ],\n            [\n              -1.69189453125,\n              41.77131167976407\n            ],\n            [\n              -1.2744140625,\n              41.36031866306708\n            ],\n            [\n              -1.2744140625,\n              40.78054143186031\n            ],\n            [\n              -2.04345703125,\n              40.094882122321174\n            ],\n            [\n              -3.40576171875,\n              39.65645604812829\n            ],\n            [\n              -4.5263671875,\n              39.06184913429154\n            ],\n            [\n              -6.08642578125,\n              38.87392853923629\n            ],\n            [\n              -7.250976562499999,\n              39.436192999314095\n            ],\n            [\n              -6.6357421875,\n              40.329795743702064\n            ],\n            [\n              -6.08642578125,\n              40.81380923056958\n            ],\n            [\n              -4.482421875,\n              41.343824581185686\n            ],\n            [\n              -3.2299804687499996,\n              41.73852846935917\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"8","issue":"10","publishingServiceCenter":{"id":12,"text":"Tacoma PSC"},"noUsgsAuthors":false,"publicationDate":"2013-10-11","publicationStatus":"PW","scienceBaseUri":"56c304c7e4b0946c652087a4","contributors":{"authors":[{"text":"Angeler, David G.","contributorId":25027,"corporation":false,"usgs":true,"family":"Angeler","given":"David G.","affiliations":[],"preferred":false,"id":620281,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Allen, Craig R. 0000-0001-8655-8272 allencr@usgs.gov","orcid":"https://orcid.org/0000-0001-8655-8272","contributorId":1979,"corporation":false,"usgs":true,"family":"Allen","given":"Craig","email":"allencr@usgs.gov","middleInitial":"R.","affiliations":[{"id":200,"text":"Coop Res Unit Seattle","active":true,"usgs":true},{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true}],"preferred":true,"id":619837,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Rojo, Carmen","contributorId":166885,"corporation":false,"usgs":false,"family":"Rojo","given":"Carmen","email":"","affiliations":[],"preferred":false,"id":620282,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Alvarez-Cobelas, Miguel","contributorId":166886,"corporation":false,"usgs":false,"family":"Alvarez-Cobelas","given":"Miguel","email":"","affiliations":[],"preferred":false,"id":620283,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Rodrigo, Maria A.","contributorId":166887,"corporation":false,"usgs":false,"family":"Rodrigo","given":"Maria","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":620284,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Sanchez-Carrillo, Salvador","contributorId":166888,"corporation":false,"usgs":false,"family":"Sanchez-Carrillo","given":"Salvador","email":"","affiliations":[],"preferred":false,"id":620285,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}
