An ensemble of watershed models was applied in the present study to simulate and evaluate the responses of hydrological and total Hg (THg) fluxes from the landscape to the watershed outlet and in-stream THg concentrations to contrasting climate change projections for a watershed in the southeastern coastal plain of the United States. Simulations were conducted under stationary atmospheric deposition and land cover conditions to explicitly evaluate the effect of projected precipitation and temperature on watershed Hg export (i.e., the flux of Hg at the watershed outlet). Based on downscaled inputs from 2 global circulation models that capture extremes of projected wet (Community Climate System Model, Ver 3 [CCSM3]) and dry (ECHAM4/HOPE-G [ECHO]) conditions for this region, watershed model simulation results suggest a decrease of approximately 19% in ensemble-averaged mean annual watershed THg fluxes using the ECHO climate-change model and an increase of approximately 5% in THg fluxes with the CCSM3 model. Ensemble-averaged mean annual ECHO in-stream THg concentrations increased 20%, while those of CCSM3 decreased by 9% between the baseline and projected simulation periods. Watershed model simulation results using both climate change models suggest that monthly watershed THg fluxes increase during the summer, when projected flow is higher than baseline conditions. The present study's multiple watershed model approach underscores the uncertainty associated with climate change response projections and their use in climate change management decisions. Thus, single-model predictions can be misleading, particularly in developmental stages of watershed Hg modeling.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Toxicology and Chemistry","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","doi":"10.1002/etc.2284","usgsCitation":"Golden, H., Knightes, C.D., Conrads, P., Feaster, T., Davis, G.M., Benedict, S., and Bradley, P.M., 2013, Climate change and watershed mercury export: a multiple projection and model analysis: Environmental Toxicology and Chemistry, v. 32, no. 9, p. 2165-2174, https://doi.org/10.1002/etc.2284.","productDescription":"10 p.","startPage":"2165","endPage":"2174","numberOfPages":"10","ipdsId":"IP-045661","costCenters":[{"id":559,"text":"South Carolina Water Science Center","active":true,"usgs":true}],"links":[{"id":278632,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":278631,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/etc.2284"}],"country":"United States","state":"South Carolina","otherGeospatial":"Mctier Creek Watershed","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -81.666667,33.7 ], [ -81.666667,33.883333 ], [ -81.533333,33.883333 ], [ -81.533333,33.7 ], [ -81.666667,33.7 ] ] ] } } ] }","volume":"32","issue":"9","noUsgsAuthors":false,"publicationDate":"2013-05-22","publicationStatus":"PW","scienceBaseUri":"5274c658e4b089748f071321","contributors":{"authors":[{"text":"Golden, Heather E.","contributorId":94914,"corporation":false,"usgs":true,"family":"Golden","given":"Heather E.","affiliations":[],"preferred":false,"id":485574,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Knightes, Christopher D.","contributorId":32666,"corporation":false,"usgs":true,"family":"Knightes","given":"Christopher","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":485573,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Conrads, Paul 0000-0003-0408-4208 pconrads@usgs.gov","orcid":"https://orcid.org/0000-0003-0408-4208","contributorId":764,"corporation":false,"usgs":true,"family":"Conrads","given":"Paul","email":"pconrads@usgs.gov","affiliations":[{"id":13634,"text":"South Atlantic Water Science Center","active":true,"usgs":true},{"id":559,"text":"South Carolina Water Science Center","active":true,"usgs":true}],"preferred":false,"id":485569,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Feaster, Toby D. 0000-0002-5626-5011 tfeaster@usgs.gov","orcid":"https://orcid.org/0000-0002-5626-5011","contributorId":1109,"corporation":false,"usgs":true,"family":"Feaster","given":"Toby D.","email":"tfeaster@usgs.gov","affiliations":[{"id":559,"text":"South Carolina Water Science Center","active":true,"usgs":true}],"preferred":false,"id":485570,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Davis, Gary M.","contributorId":12741,"corporation":false,"usgs":true,"family":"Davis","given":"Gary","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":485572,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Benedict, Stephen T. benedict@usgs.gov","contributorId":3198,"corporation":false,"usgs":true,"family":"Benedict","given":"Stephen T.","email":"benedict@usgs.gov","affiliations":[{"id":559,"text":"South Carolina Water Science Center","active":true,"usgs":true}],"preferred":false,"id":485571,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Bradley, Paul M. 0000-0001-7522-8606 pbradley@usgs.gov","orcid":"https://orcid.org/0000-0001-7522-8606","contributorId":361,"corporation":false,"usgs":true,"family":"Bradley","given":"Paul","email":"pbradley@usgs.gov","middleInitial":"M.","affiliations":[{"id":13634,"text":"South Atlantic Water Science Center","active":true,"usgs":true}],"preferred":true,"id":485568,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

Published decay rates, available for many species, are commonly used to characterize deadwood biomass and carbon depletion. However, decay rates are often derived from reductions in wood density through time, which when used to model biomass and carbon depletion are known to underestimate rate loss because they fail to account for volume reduction (changes in log shape) as decay progresses. We present a method for estimating changes in log volume through time and illustrate the method using a chronosequence approach. The method is based on the observation, confirmed herein, that decaying logs have a collapse ratio (cross-sectional height/width) that can serve as a surrogate for the volume remaining. Combining the resulting volume loss with concurrent changes in wood density from the same logs then allowed us to quantify biomass and carbon depletion for three study species. Results show that volume, density, and biomass follow distinct depletion curves during decomposition. Volume showed an initial lag period (log dimensions remained unchanged), even while wood density was being reduced. However, once volume depletion began, biomass loss (the product of density and volume depletion) occurred much more rapidly than density alone. At the temporal limit of our data, the proportion of the biomass remaining was roughly half that of the density remaining. Accounting for log volume depletion, as demonstrated in this study, provides a comprehensive characterization of deadwood decomposition, thereby improving biomass-loss and carbon-accounting models.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecosystems","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer","doi":"10.1007/s10021-013-9682-z","usgsCitation":"Fraver, S., Milo, A.M., Bradford, J.B., D’Amato, A.W., Kenefic, L., Palik, B.J., Woodall, C.W., and Brissette, J., 2013, Woody debris volume depletion through decay: implications for biomass and carbon accounting: Ecosystems, v. 16, no. 7, p. 1262-1272, https://doi.org/10.1007/s10021-013-9682-z.","productDescription":"11 p.","startPage":"1262","endPage":"1272","numberOfPages":"11","ipdsId":"IP-042518","costCenters":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"links":[{"id":282669,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":282639,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10021-013-9682-z"}],"country":"United States","state":"Minnesota","otherGeospatial":"Laurentian Mixed Forest Province","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -95.81,45.41 ], [ -95.81,49.38 ], [ -89.49,49.38 ], [ -89.49,45.41 ], [ -95.81,45.41 ] ] ] } } ] }","volume":"16","issue":"7","noUsgsAuthors":false,"publicationDate":"2013-06-08","publicationStatus":"PW","scienceBaseUri":"53cd7dcce4b0b2908510f9b6","contributors":{"authors":[{"text":"Fraver, Shawn","contributorId":91379,"corporation":false,"usgs":false,"family":"Fraver","given":"Shawn","email":"","affiliations":[{"id":7063,"text":"University of Maine","active":true,"usgs":false}],"preferred":false,"id":490749,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Milo, Amy M.","contributorId":83441,"corporation":false,"usgs":true,"family":"Milo","given":"Amy","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":490747,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bradford, John B. 0000-0001-9257-6303 jbradford@usgs.gov","orcid":"https://orcid.org/0000-0001-9257-6303","contributorId":611,"corporation":false,"usgs":true,"family":"Bradford","given":"John","email":"jbradford@usgs.gov","middleInitial":"B.","affiliations":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"preferred":true,"id":490742,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"D’Amato, Anthony W.","contributorId":28140,"corporation":false,"usgs":false,"family":"D’Amato","given":"Anthony","email":"","middleInitial":"W.","affiliations":[{"id":6735,"text":"University of Vermont, Rubenstein School of Environment and Natural Resources","active":true,"usgs":false},{"id":13478,"text":"Department of Forest Resources, University of Minnesota, St. Paul, Minnesota (Correspondence to: russellm@umn.edu)","active":true,"usgs":false}],"preferred":false,"id":490743,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Kenefic, Laura","contributorId":86685,"corporation":false,"usgs":true,"family":"Kenefic","given":"Laura","affiliations":[],"preferred":false,"id":490748,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Palik, Brian J.","contributorId":78619,"corporation":false,"usgs":true,"family":"Palik","given":"Brian","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":490746,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Woodall, Christopher W.","contributorId":53696,"corporation":false,"usgs":false,"family":"Woodall","given":"Christopher","email":"","middleInitial":"W.","affiliations":[{"id":7264,"text":"USDA Forest Service, Northern Research Station, Beltsville, MD 20705","active":true,"usgs":false}],"preferred":false,"id":490745,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Brissette, John","contributorId":50077,"corporation":false,"usgs":true,"family":"Brissette","given":"John","email":"","affiliations":[],"preferred":false,"id":490744,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

Reductions in the area of open water in the Atchafalaya have been occurring over the last 100 years, and many historical waterways are increasingly filled by sediment. This study examines two cases of swamp channels (< 85 m<sup>3</sup>/s) that are filling and becoming unnavigable as a result of high sediment loads and slow water velocities. The water velocities in natural bayous are further reduced because of flow capture by channels constructed for access. Bathymetry, flow, suspended sediment, deposited bottom-material, isotopes, and photointerpretation were used to characterize the channel fill. On average, water flowing through these two channels lost 23% of the suspended sediment load in the studied reaches. Along one of the studied reaches, two constructed access channels diverted significant flow out of the primary channel and into the adjacent swamp. Immediately downstream of each of the two access channels, the cross-sectional area of the studied channel was reduced. Isotopic analyses of bottom-material cores indicate that bed filling has been rapid and occurred after detectable levels of Cesium-137 were no longer being deposited. Interpretation of aerial photography indicates that water is bypassing the primary channels in favor of the more hydraulically efficient access channels, resulting in low or no-velocity flow conditions in the primary channel. These swamp channel conditions are typical in the Atchafalaya River Basin where relict large channel dimensions result in flow velocities that are normally too low to carry fine-grained sediment. Constructed channels increase the rate of natural channel avulsion and abandonment as a result of flow capture.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geomorphology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.geomorph.2013.06.016","usgsCitation":"Kroes, D.E., and Kraemer, T.F., 2013, Human-induced stream channel abandonment/capture and filling of floodplain channels within the Atchafalaya River Basin, Louisiana: Geomorphology, v. 201, p. 148-156, https://doi.org/10.1016/j.geomorph.2013.06.016.","productDescription":"9 p.","startPage":"148","endPage":"156","numberOfPages":"9","ipdsId":"IP-042681","costCenters":[{"id":369,"text":"Louisiana Water Science Center","active":true,"usgs":true}],"links":[{"id":289782,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":289781,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.geomorph.2013.06.016"}],"country":"United States","state":"Louisiana","otherGeospatial":"Atchafalaya River Basin;Big Bayou Pigeon","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -91.5,29.75 ], [ -91.5,30.25 ], [ -91.25,30.25 ], [ -91.25,29.75 ], [ -91.5,29.75 ] ] ] } } ] }","volume":"201","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53c0ec44e4b065ccca5fe3d2","contributors":{"authors":[{"text":"Kroes, Daniel E.","contributorId":32260,"corporation":false,"usgs":true,"family":"Kroes","given":"Daniel","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":495759,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kraemer, Thomas F. tkraemer@usgs.gov","contributorId":3443,"corporation":false,"usgs":true,"family":"Kraemer","given":"Thomas","email":"tkraemer@usgs.gov","middleInitial":"F.","affiliations":[{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true}],"preferred":true,"id":495758,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

However, tidal interactions near tributary mouths can affect the magnitude and direction of sediment supply to the open waters of the estuary. We investigated suspended-sediment dynamics in the tidal reach of Corte Madera Creek, an estuarine tributary of San Francisco Bay, using moored acoustic and optical instruments. Flux of both water and suspended-sediment were calculated from observed water velocity and turbidity for two periods in each of wet and dry seasons during 2010. During wet periods, net suspended-sediment flux was seaward; tidally filtered flux was dominated by the advective component. In contrast, during dry periods, net flux was landward; tidally filtered flux was dominated by the dispersive component. The mechanisms generating this landward flux varied; during summer we attributed wind–wave resuspension in the estuary and subsequent transport on flood tides, whereas during autumn we attributed increased spring tide flood velocity magnitude leading to local resuspension. A quadrant analysis similar to that employed in turbulence studies was developed to summarize flux time series by quantifying the relative importance of sediment transport events. These events are categorized by the direction of velocity (flood vs. ebb) and the magnitude of concentration relative to tidally averaged conditions (relatively turbid vs. relatively clear). During wet periods, suspended-sediment flux was greatest in magnitude during relatively turbid ebbs, whereas during dry periods it was greatest in magnitude during relatively turbid floods. A conceptual model was developed to generalize seasonal differences in suspended-sediment dynamics; model application to this study demonstrated the importance of few, relatively large events on net suspended-sediment flux. These results suggest that other estuarine tributaries may alternate seasonally as sediment sinks or sources, leading to the conclusion that calculations of estuary sediment supply from local tributaries that do not account for tidal reaches may be overestimates.","language":"English","publisher":"Elsevier","doi":"10.1016/j.margeo.2013.03.005","usgsCitation":"Downing-Kunz, M., and Schoellhamer, D., 2013, Seasonal variations in suspended-sediment dynamics in the tidal reach of an estuarine tributary: Marine Geology, v. 345, p. 314-326, https://doi.org/10.1016/j.margeo.2013.03.005.","productDescription":"13 p.","startPage":"314","endPage":"326","numberOfPages":"13","ipdsId":"IP-021925","costCenters":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true},{"id":552,"text":"San Francisco Bay-Delta","active":false,"usgs":true}],"links":[{"id":282667,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"Corte Madera Creek, San Francisco Bay","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -122.666667,37.916667 ], [ -122.666667,38.0 ], [ -122.5,38.0 ], [ -122.5,37.916667 ], [ -122.666667,37.916667 ] ] ] } } ] }","volume":"345","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd71b5e4b0b29085107db2","contributors":{"editors":[{"text":"Barnard, Patrick L. 0000-0003-1414-6476 pbarnard@usgs.gov","orcid":"https://orcid.org/0000-0003-1414-6476","contributorId":147147,"corporation":false,"usgs":true,"family":"Barnard","given":"Patrick L.","email":"pbarnard@usgs.gov","affiliations":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":true,"id":790440,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Jaffe, Bruce E. 0000-0002-8816-5920 bjaffe@usgs.gov","orcid":"https://orcid.org/0000-0002-8816-5920","contributorId":2049,"corporation":false,"usgs":true,"family":"Jaffe","given":"Bruce","email":"bjaffe@usgs.gov","middleInitial":"E.","affiliations":[{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true},{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":true,"id":790441,"contributorType":{"id":2,"text":"Editors"},"rank":2},{"text":"Schoellhamer, David H. 0000-0001-9488-7340 dschoell@usgs.gov","orcid":"https://orcid.org/0000-0001-9488-7340","contributorId":631,"corporation":false,"usgs":true,"family":"Schoellhamer","given":"David H.","email":"dschoell@usgs.gov","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":true,"id":790442,"contributorType":{"id":2,"text":"Editors"},"rank":3}],"authors":[{"text":"Downing-Kunz, Maureen A. 0000-0002-4879-0318","orcid":"https://orcid.org/0000-0002-4879-0318","contributorId":57552,"corporation":false,"usgs":true,"family":"Downing-Kunz","given":"Maureen A.","affiliations":[],"preferred":false,"id":490796,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Schoellhamer, David H. 0000-0001-9488-7340 dschoell@usgs.gov","orcid":"https://orcid.org/0000-0001-9488-7340","contributorId":631,"corporation":false,"usgs":true,"family":"Schoellhamer","given":"David H.","email":"dschoell@usgs.gov","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":true,"id":490795,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Since this introduction, Cuban Treefrogs have spread to Miami and are now established throughout most of peninsular Florida. Cuban Treefrogs can become very abundant in areas they colonize. Several reasons contribute to their success, including a generalist diet, high fecundity and the ability to reproduce year-round, and use of disturbed or human-modified habitats. Scientists and managers are concerned that Cuban Treefrogs may contribute to the decline of native treefrogs. Cuban Treefrogs may exclude native treefrogs through both competition and predation. Because the evidence from our study and others suggests that Green and Squirrel Treefrogs do not alter their behavior to avoid Cuban Treefrogs, there is cause for concern that sampling with PVC pipes may increase the vulnerability of the native species to predation. This possibility needs further research, including whether other species of native treefrogs sympatric to where Cuban Treefrogs have invaded are also naïve to the possible threat posed by these frogs, and also if native treefrogs eventually learn to avoid Cuban Treefrogs.</p>","language":"English","publisher":"Society for the Study of Amphibians and Reptiles","usgsCitation":"Elston, L.M., Waddle, J., Rice, K.G., and Percival, H.F., 2013, Co-occurrence of invasive Cuban Treefrogs and native treefrogs in PVC pipe refugia: Herpetological Review, v. 44, no. 3, p. 406-409.","productDescription":"4 p.","startPage":"406","endPage":"409","ipdsId":"IP-024733","costCenters":[{"id":455,"text":"National Wetlands Research Center","active":true,"usgs":true},{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true}],"links":[{"id":278904,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":278597,"type":{"id":15,"text":"Index Page"},"url":"https://zenscientist.com/index.php/zenscientist-news/entry/herpetological-review-44-3"}],"country":"United States","state":"Florida","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -81.5212,24.85 ], [ -81.5212,25.8918 ], [ -80.3887,25.8918 ], [ -80.3887,24.85 ], [ -81.5212,24.85 ] ] ] } } ] }","volume":"44","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"527cc48ae4b0850ea050ce3a","contributors":{"authors":[{"text":"Elston, Laura M.","contributorId":34028,"corporation":false,"usgs":true,"family":"Elston","given":"Laura","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":485484,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Waddle, J.

Dissimilarity is calculated and used in nonmetric multidimensional scaling for repeated measures of vascular species cover at 14 GLORIA sites with 525 nearby sites and with 436 sites in western North America. The lengths of the trajectories of the GLORIA sites in ordination space are compared to the dimensions of the space created by the larger datasets. The absolute amount of change on the GLORIA summits over 5 years is high, but the degree of change is small relative to the geographical context. The GLORIA sites are on the margin of the ordination volumes with the large datasets.

One model suggests that increased gustiness (stronger, more frequent winds) enhanced dustiness. We tested this at Loveland, Iowa, one of the thickest deposits of last-glacial-age (Peoria) loess in the world. Based on K/Rb and Ba/Rb, loess was derived not only from glaciogenic sources of the Missouri River, but also distal loess from non-glacial sources in Nebraska. Optically stimulated luminescence (OSL) ages provide the first detailed chronology of Peoria Loess at Loveland. Deposition began after ~ 27 ka and continued until ~ 17 ka. OSL ages also indicate that mass accumulation rates (MARs) of loess were not constant. MARs were highest and grain size was coarsest during the time of middle Peoria Loess accretion, ~ 23 ka, when ~ 10 m of loess accumulated in no more than ~ 2000 yr and possibly much less. The timing of coarsest grain size and highest MAR, indicating strongest winds, coincides with a summer-insolation minimum at high latitudes in North America and the maximum southward extent of the Laurentide ice sheet. These observations suggest that increased dustiness during the last glacial period was driven largely by enhanced gustiness, forced by a steepened meridional temperature gradient.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Quaternary Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Academic Press","publisherLocation":"New York, NY","doi":"10.1016/j.yqres.2013.06.006","usgsCitation":"Muhs, D.R., Bettis, E., Roberts, H.M., Harlan, S.S., Paces, J.B., and Reynolds, R.L., 2013, Chronology and provenance of last-glacial (Peoria) loess in western Iowa and paleoclimatic implications: Quaternary Research, v. 80, no. 3, p. 468-481, https://doi.org/10.1016/j.yqres.2013.06.006.","productDescription":"14 p.","startPage":"468","endPage":"481","numberOfPages":"14","ipdsId":"IP-042020","costCenters":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"links":[{"id":293902,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":293901,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.yqres.2013.06.006"}],"volume":"80","issue":"3","noUsgsAuthors":false,"publicationDate":"2017-01-20","publicationStatus":"PW","scienceBaseUri":"54195127e4b091c7ffc8e5e9","contributors":{"authors":[{"text":"Muhs, Daniel R. 0000-0001-7449-251X dmuhs@usgs.gov","orcid":"https://orcid.org/0000-0001-7449-251X","contributorId":1857,"corporation":false,"usgs":true,"family":"Muhs","given":"Daniel","email":"dmuhs@usgs.gov","middleInitial":"R.","affiliations":[{"id":218,"text":"Denver Federal Center","active":false,"usgs":true}],"preferred":true,"id":501186,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bettis, E.

The trip will follow the precedent set in 1901; CSS members will serve as “site or stop hosts” in addition to the trip leader and drivers. While walking in the steps of the most famous of our profession we will also see some of the most magnificent scenery of Colorado.</span></p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Classic concepts and new directions: Exploring 125 years of GSA discoveries in the Rocky Mountain region","largerWorkSubtype":{"id":15,"text":"Monograph"},"language":"English","publisher":"Geological Society of America","doi":"10.1130/2013.0033(02)","usgsCitation":"Simmons, B., 2013, Colorado geology then and now: Following the route of the Colorado Scientific Society’s 1901 trip through central Colorado, chap. 2 <i>of</i> Classic concepts and new directions: Exploring 125 years of GSA discoveries in the Rocky Mountain region, p. 19-83, https://doi.org/10.1130/2013.0033(02).","productDescription":"64 p.","startPage":"19","endPage":"83","ipdsId":"IP-049207","costCenters":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"links":[{"id":284307,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Colorado","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -107.808837890625,\n              37.85750715625203\n            ],\n            [\n              -107.808837890625,\n              40.30466538259176\n            ],\n            [\n              -104.0185546875,\n              40.30466538259176\n            ],\n            [\n              -104.0185546875,\n              37.85750715625203\n            ],\n            [\n              -107.808837890625,\n              37.85750715625203\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd594de4b0b290850f8a27","contributors":{"editors":[{"text":"Abbott, Lon D.","contributorId":1134,"corporation":false,"usgs":false,"family":"Abbott","given":"Lon","email":"","middleInitial":"D.","affiliations":[{"id":6713,"text":"University of Colorado, Boulder CO","active":true,"usgs":false}],"preferred":false,"id":509373,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Hancock, Gregory S.","contributorId":85096,"corporation":false,"usgs":false,"family":"Hancock","given":"Gregory","email":"","middleInitial":"S.","affiliations":[{"id":6686,"text":"College of William and Mary","active":true,"usgs":false}],"preferred":false,"id":742714,"contributorType":{"id":2,"text":"Editors"},"rank":2}],"authors":[{"text":"Simmons, Beth","contributorId":146882,"corporation":false,"usgs":false,"family":"Simmons","given":"Beth","email":"","affiliations":[],"preferred":false,"id":481082,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

As a result of regional groundwater overdrafts prior to the 1970s, parts of the project area have subsided below sea-level and will require between 29 and 45 million m<sup>3</sup> of sediment to raise the surface of the subsided areas to elevations appropriate for tidal marsh colonization and development. Therefore, a sufficient sediment supply to the far south SFB subembayment is a critical variable for achieving restoration goals. Although both major tributaries to far south SFB have been seasonally gaged for sediment since 2004, the sediment flux at the Dumbarton Narrows, the bayward boundary of far south SFB, has not been quantified until recently. Using daily suspended-sediment flux data from the gages on Guadalupe River and Coyote Creek, combined with continuous suspended-sediment flux data at Dumbarton Narrows, we computed a sediment budget for far south SFB during Water Years 2009–2011. A Monte Carlo approach was used to quantify the uncertainty of the flux estimates. The sediment flux past Dumbarton Narrows from the north dominates the input to the subembayment. However, environmental conditions in the spring can dramatically influence the direction of springtime flux, which appears to be a dominant influence on the net annual flux. It is estimated that up to several millennia may be required for natural tributary sediments to fill the accommodation space of the subsided former salt ponds, whereas supply from the rest of the bay could fill the space in several centuries. Uncertainty in the measurement of sediment flux is large, in part because small suspended-sediment concentration differences between flood and ebb tides can lead to large differences in total mass exchange. Using Monte Carlo simulations to estimate the random error associated with this uncertainty provides a more statistically rigorous method of quantifying this uncertainty than the more typical “sum of errors” approach. The results of this study reinforce the need for measurement of estuarine sediment fluxes over multiple years (multiple hydrologic conditions) to adequately detail the variability in flux. Additionally, the timing of breaching events for the restoration project could be tied to annual hydrologic conditions to capitalize on increased regional sediment supply.","language":"English","publisher":"Elsevier","doi":"10.1016/j.margeo.2013.05.007","usgsCitation":"Shellenbarger, G., Wright, S., and Schoellhamer, D., 2013, A sediment budget for the southern reach in San Francisco Bay, CA: Implications for habitat restoration: Marine Geology, v. 345, p. 281-293, https://doi.org/10.1016/j.margeo.2013.05.007.","productDescription":"13 p.","startPage":"281","endPage":"293","numberOfPages":"13","ipdsId":"IP-006338","costCenters":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true},{"id":552,"text":"San Francisco Bay-Delta","active":false,"usgs":true}],"links":[{"id":287278,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"San Francisco Bay","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -122.75,37.2509 ], [ -122.75,38.3523 ], [ -121.6589,38.3523 ], [ -121.6589,37.2509 ], [ -122.75,37.2509 ] ] ] } } ] }","volume":"345","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"537b27e6e4b0929ba496ab48","contributors":{"authors":[{"text":"Shellenbarger, Gregory gshellen@usgs.gov","contributorId":1133,"corporation":false,"usgs":true,"family":"Shellenbarger","given":"Gregory","email":"gshellen@usgs.gov","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":false,"id":493821,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wright, Scott 0000-0002-0387-5713 sawright@usgs.gov","orcid":"https://orcid.org/0000-0002-0387-5713","contributorId":1536,"corporation":false,"usgs":true,"family":"Wright","given":"Scott","email":"sawright@usgs.gov","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":true,"id":493822,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Schoellhamer, David H. 0000-0001-9488-7340 dschoell@usgs.gov","orcid":"https://orcid.org/0000-0001-9488-7340","contributorId":631,"corporation":false,"usgs":true,"family":"Schoellhamer","given":"David H.","email":"dschoell@usgs.gov","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":true,"id":493820,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

In this study, Earth observation satellite data were used to map global forest loss (2.3 million square kilometers) and gain (0.8 million square kilometers) from 2000 to 2012 at a spatial resolution of 30 meters. The tropics were the only climate domain to exhibit a trend, with forest loss increasing by 2101 square kilometers per year. Brazil’s well-documented reduction in deforestation was offset by increasing forest loss in Indonesia, Malaysia, Paraguay, Bolivia, Zambia, Angola, and elsewhere. Intensive forestry practiced within subtropical forests resulted in the highest rates of forest change globally. Boreal forest loss due largely to fire and forestry was second to that in the tropics in absolute and proportional terms. These results depict a globally consistent and locally relevant record of forest change.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Science","largerWorkSubtype":{"id":10,"text":"Journal Article"},"doi":"10.1126/science.1244693","usgsCitation":"Hansen, M.,

Diseases are typically named or described based on macroscopic changes, but broad signs of coral distress such as tissue loss or discoloration are unlikely to be specific to a particular pathogen. For example, there appear to be multiple diseases that manifest the rapid tissue loss that characterizes &lsquo;white plague.&rsquo; PhyloChip&trade; G3 microarrays were used to compare the bacterial community composition of both healthy and white plague-like diseased corals. Samples of lobed star coral (</span><i>Orbicella annularis</i><span>, formerly of the genus&nbsp;</span><i>Montastraea</i><span>&nbsp;</span><a class=\"ref-tip\" href=\"http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0079801#pone.0079801-Budd1\">[1]</a><span>) were collected from two geographically distinct areas, Dry Tortugas National Park and Virgin Islands National Park, to determine if there were biogeographic differences between the diseases. In fact, all diseased samples clustered together, however there was no consistent link to&nbsp;</span><i>Aurantimonas coralicida</i><span>, which has been described as the causative agent of white plague type II. The microarrays revealed a large amount of bacterial heterogeneity within the healthy corals and less diversity in the diseased corals. Gram-positive bacterial groups (Actinobacteria, Firmicutes) comprised a greater proportion of the operational taxonomic units (OTUs) unique to healthy samples.

Here we report on the first study to couple optically stimulated luminescence (OSL) ages of quartz sand deposits and accelerator mass spectrometry <sup>14</sup>C ages measured on benthic foraminifera to examine the timing of sediment transport through the axial channel of Monterey Submarine Canyon and Fan, offshore California. The OSL ages date the timing of sediment entry into the canyon head while the <sup>14</sup>C ages of benthic foraminifera record the deposition of hemipelagic sediments that bound the sand horizons. We use both single-grain and small (&sim;2 mm area) single-aliquot regeneration approaches on vibracore samples from fining-upward sequences at various water depths to demonstrate relatively rapid, decadal-scale sand transport to at least 1.1 km depth and more variable decadal- to millennial-scale transport to a least 3.5 km depth on the fan. Significant differences between the time sand was last exposed at the canyon head (OSL age) and the timing of deposition of the sand (from <sup>14</sup>C ages of benthic foraminifera in bracketing hemipelagic sediments) are interpreted as indicating that the sand does not pass through the entire canyon instantly in large individual events, but rather moves multiple times before emerging onto the fan. The increased spread in single-grain OSL dates with water depth provides evidence of mixing and temporary storage of sediment as it moves through the canyon system. The ages also indicate that the frequency of sediment transport events decreases with distance down the canyon channel system. The amalgamated sands near the canyon head yield OSL ages that are consistent with a sub-decadal recurrence frequency while the fining-upward sand sequences on the fan indicate that the channel is still experiencing events with a 150&ndash;250 year recurrence frequency out to 3.5 km water depths.&nbsp; &nbsp;&nbsp;</p>","language":"English","publisher":"Geological Society of America","doi":"10.1130/B30931.1","usgsCitation":"Stevens, T., Paull, C.K., Ussler, W., McGann, M., Buylaert, J., and Lundsten, E.M., 2013, The timing of sediment transport down Monterey Submarine Canyon, offshore California: Geological Society of America Bulletin, v. 126, no. 1, p. 103-121, https://doi.org/10.1130/B30931.1.","productDescription":"19 p.","startPage":"103","endPage":"121","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-062628","costCenters":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":327123,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -123.5,\n              37\n            ],\n            [\n              -123.5,\n              36\n            ],\n            [\n              -121.5,\n              36\n            ],\n            [\n              -121.5,\n              37\n            ],\n            [\n              -123.5,\n              37\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"126","issue":"1","publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationDate":"2013-11-22","publicationStatus":"PW","scienceBaseUri":"57b97f29e4b03fd6b7db87db","contributors":{"authors":[{"text":"Stevens, Thomas","contributorId":173895,"corporation":false,"usgs":false,"family":"Stevens","given":"Thomas","affiliations":[{"id":27154,"text":"Royal Holloway, University of London","active":true,"usgs":false}],"preferred":false,"id":646531,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Paull, Charles K. 0000-0001-5940-3443","orcid":"https://orcid.org/0000-0001-5940-3443","contributorId":55825,"corporation":false,"usgs":false,"family":"Paull","given":"Charles","email":"","middleInitial":"K.","affiliations":[{"id":7043,"text":"University of North Carolina","active":true,"usgs":false}],"preferred":true,"id":646532,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Ussler, William","contributorId":173896,"corporation":false,"usgs":false,"family":"Ussler","given":"William","email":"","affiliations":[{"id":13620,"text":"Monterey Bay Aquarium Research Institute, Moss Landing, California","active":true,"usgs":false}],"preferred":false,"id":646533,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"McGann, Mary 0000-0002-3057-2945 mmcgann@usgs.gov","orcid":"https://orcid.org/0000-0002-3057-2945","contributorId":169540,"corporation":false,"usgs":true,"family":"McGann","given":"Mary","email":"mmcgann@usgs.gov","affiliations":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true},{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true}],"preferred":true,"id":646530,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Buylaert, Jan-Pieter","contributorId":173897,"corporation":false,"usgs":false,"family":"Buylaert","given":"Jan-Pieter","email":"","affiliations":[{"id":13419,"text":"Aarhus University, Denmark","active":true,"usgs":false}],"preferred":false,"id":646535,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Lundsten, Eve M.","contributorId":147191,"corporation":false,"usgs":false,"family":"Lundsten","given":"Eve","email":"","middleInitial":"M.","affiliations":[{"id":13620,"text":"Monterey Bay Aquarium Research Institute, Moss Landing, California","active":true,"usgs":false}],"preferred":false,"id":646534,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

DOC concentrations and compositions at the mouth appear to be primarily influenced by land use (agriculture) in the lower reaches, and therefore very little of the headwater chemistry (1st and 2nd order streams) can be discerned from the chemistry at or near the mouth (3rd and 4th order streams), indicating the need for synoptic sampling to capture the breadth of organic carbon cycling within a catchment. Field sampling during irrigation showed the large impact that flood irrigation can have on DOC concentrations and compositions, likely a primary cause of significantly elevated Willow Slough DOC concentrations during the summer irrigation season. Optical proxies exhibited varying degrees of correlation with chemical measurements, with strongest relationships to DOC and dissolved lignin (</span><i>r</i><sup>2</sup><span>&nbsp;=&nbsp;0.95 and 0.73, respectively) and weaker relationships to carbon-normalized lignin yields and C:V (</span><i>r</i><sup>2</sup><span>&nbsp;from 0.31 to 0.42). Demonstrating the importance of matching scale to processes, we found no relationship between dissolved lignin concentrations and total suspended sediments (TSS) across all sites, in contrast to the strong relationship observed in weekly samples at the mouth. As DOC concentrations and compositions at the mouth of Willow Slough are closely tied to anthropogenic activities within the catchment, future changes in land-use driven by climate change, water availability, and economic pressures on crop types will also bring about changes in the overall biogeochemistry.</span></p>","language":"English","publisher":"Elselvier","doi":"10.1016/j.gca.2013.07.039","collaboration":"CALFED","usgsCitation":"Hernes, P.J., Spencer, R., Dyda, R.Y., Pellerin, B.A., Bachand, P., and Bergamaschi, B., 2013, DOM composition in an agricultural watershed: assessing patterns and variability in the context of spatial scales: Geochimica et Cosmochimica Acta, v. 121, p. 599-610, https://doi.org/10.1016/j.gca.2013.07.039.","productDescription":"12 p.","startPage":"599","endPage":"610","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-051121","costCenters":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"links":[{"id":298739,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"Sacramento River valley","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -122.59643554687499,\n              37.90953361677018\n            ],\n            [\n              -122.59643554687499,\n              41.36856413680967\n            ],\n            [\n              -121.36596679687499,\n              41.36856413680967\n            ],\n            [\n              -121.36596679687499,\n              37.90953361677018\n            ],\n            [\n              -122.59643554687499,\n              37.90953361677018\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"121","publishingServiceCenter":{"id":1,"text":"Sacramento PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"550bf32be4b02e76d759cde0","contributors":{"authors":[{"text":"Hernes, Peter J.","contributorId":139730,"corporation":false,"usgs":false,"family":"Hernes","given":"Peter","email":"","middleInitial":"J.","affiliations":[{"id":12894,"text":"Department of Land, Air, and Water Resources, University of California, One Shields Avenue, Davis, CA, 95616, USA","active":true,"usgs":false}],"preferred":false,"id":542699,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Spencer, Robert G.

Increasing technological advances, however, have produced statistical challenges in analysing such highly autocorrelated data. Weighted distribution methods have been proposed for analysing RSFs with telemetry data. However, they can be computationally challenging due to an intractable normalizing constant and cannot be aggregated (i.e. collapsed) over time to make space-only inference.\nIn this study, we take a conceptually different approach to modelling animal telemetry data for making RSF inference. We consider the telemetry data to be a realization of a space–time point process. Under the point process paradigm, the times of the relocations are also considered to be random rather than fixed.\nWe show the point process models we propose are a generalization of the weighted distribution telemetry models. By generalizing the weighted model, we can access several numerical techniques for evaluating point process likelihoods that make use of common statistical software. Thus, the analysis methods can be readily implemented by animal ecologists.\nIn addition to ease of computation, the point process models can be aggregated over time by marginalizing over the temporal component of the model. This allows a full range of models to be constructed for RSF analysis at the individual movement level up to the study area level.\nTo demonstrate the analysis of telemetry data with the point process approach, we analysed a data set of telemetry locations from northern fur seals (Callorhinus ursinus) in the Pribilof Islands, Alaska. Both a space–time and an aggregated space-only model were fitted. At the individual level, the space–time analysis showed little selection relative to the habitat covariates. However, at the study area level, the space-only model showed strong selection relative to the covariates.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Animal Ecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","doi":"10.1111/1365-2656.12087","usgsCitation":"Johnson, D., Hooten, M., and Kuhn, C.E., 2013, Estimating animal resource selection from telemetry data using point process models: Journal of Animal Ecology, v. 82, no. 6, p. 1155-1164, https://doi.org/10.1111/1365-2656.12087.","productDescription":"10 p.","startPage":"1155","endPage":"1164","numberOfPages":"10","ipdsId":"IP-039994","costCenters":[{"id":200,"text":"Coop Res Unit Seattle","active":true,"usgs":true}],"links":[{"id":473466,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1111/1365-2656.12087","text":"Publisher Index Page"},{"id":278937,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":278936,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/1365-2656.12087"}],"country":"United States","state":"Alaska","otherGeospatial":"Pribilof Islands","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -170.42,56.53 ], [ -170.42,57.25 ], [ -169.46,57.25 ], [ -169.46,56.53 ], [ -170.42,56.53 ] ] ] } } ] }","volume":"82","issue":"6","noUsgsAuthors":false,"publicationDate":"2013-06-25","publicationStatus":"PW","scienceBaseUri":"527cc48de4b0850ea050ce5d","contributors":{"authors":[{"text":"Johnson, Devin S.","contributorId":47524,"corporation":false,"usgs":true,"family":"Johnson","given":"Devin S.","affiliations":[],"preferred":false,"id":471984,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hooten, Mevin 0000-0002-1614-723X mhooten@usgs.gov","orcid":"https://orcid.org/0000-0002-1614-723X","contributorId":2958,"corporation":false,"usgs":true,"family":"Hooten","given":"Mevin","email":"mhooten@usgs.gov","affiliations":[{"id":12963,"text":"Colorado Cooperative Fish and Wildlife Research Unit, Fort Collins, CO","active":true,"usgs":false},{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":true,"id":471982,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kuhn, Carey E.","contributorId":42128,"corporation":false,"usgs":true,"family":"Kuhn","given":"Carey","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":471983,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The following species were tested: amphipods (</span><i>Hyalella azteca</i><span>,<span>&nbsp;</span></span><i>Gammarus pseudolimnaeus</i><span>), mayflies (</span><i>Hexagenia</i><span><span>&nbsp;</span>sp.), oligochaetes (</span><i>Tubifex tubifex</i><span>,<span>&nbsp;</span></span><i>Lumbriculus variegatus</i><span>), mussels (</span><i>Lampsilis siliquoidea</i><span>), and midges (</span><i>Chironomus dilutus</i><span>,<span>&nbsp;</span></span><i>Chironomus riparius</i><span>). In the second phase, tests were conducted with the most sensitive species in 6 additional spiked sediments, thus generating chronic toxicity data for a total of 8 nickel-spiked sediments. A species sensitivity distribution was elaborated based on 10% effective concentrations yielding a threshold value of 94&thinsp;mg Ni/kg dry weight under reasonable worst-case conditions. Data from all sediments were used to model predictive bioavailability relationships between chronic toxicity thresholds (20% effective concentrations) and AVS and Fe, and these models were used to derive site-specific sediment-quality criteria. Normalization of toxicity values reduced the intersediment variability in toxicity values significantly for the amphipod species<span>&nbsp;</span></span><i>Hyalella azteca</i><span><span>&nbsp;</span>and<span>&nbsp;</span></span><i>G. pseudolimnaeus</i><span>, but these relationships were less clearly defined for the mayfly<span>&nbsp;</span></span><i>Hexagenia</i><span><span>&nbsp;</span>sp. Application of the models to prevailing local conditions resulted in threshold values ranging from 126&thinsp;mg to 281&thinsp;mg Ni/kg dry weight, based on the AVS model, and 143&thinsp;mg to 265&thinsp;mg Ni/kg dry weight, based on the Fe model</span></p>","language":"English","publisher":"Wiley","doi":"10.1002/etc.2373","usgsCitation":"Vangheluwe, M.L., Verdonck, F.A., Besser, J.M., Brumbaugh, W.G., Ingersoll, C.G., Schlekat, C.E., and Rogevich Garman, E., 2013, Improving sediment-quality guidelines for nickel: development and application of predictive bioavailability models to assess chronic toxicity of nickel in freshwater sediments: Environmental Toxicology and Chemistry, v. 32, no. 11, p. 2507-2519, https://doi.org/10.1002/etc.2373.","productDescription":"13 p.","startPage":"2507","endPage":"2519","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-045453","costCenters":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"links":[{"id":297915,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"32","issue":"11","publishingServiceCenter":{"id":4,"text":"Rolla PSC"},"noUsgsAuthors":false,"publicationDate":"2013-08-24","publicationStatus":"PW","scienceBaseUri":"54dd2bd2e4b08de9379b34f8","contributors":{"authors":[{"text":"Vangheluwe, Marnix L.

On February 7, 2012, the USGS conducted an oblique aerial photographic survey from Pensacola, Fla., to Breton Islands, La., aboard a Piper Navajo Chieftain at an altitude of 500 feet (ft) and approximately 1,000 ft offshore. This mission was flown to collect baseline data for assessing incremental changes since the last survey, and the data can be used in the assessment of future coastal change. The photographs provided here are Joint Photographic Experts Group (JPEG) images. The photograph locations are an estimate of the position of the aircraft and do not indicate the location of the feature in the images (see the Navigation Data page). These photos document the configuration of the barrier islands and other coastal features at the time of the survey. The header of each photo is populated with time of collection, Global Positioning System (GPS) latitude, GPS longitude, GPS position (latitude and longitude), keywords, credit, artist (photographer), caption, copyright, and contact information using EXIFtools (Subino and others, 2012). Photographs can be opened directly with any JPEG-compatible image viewer by clicking on a thumbnail on the contact sheet. Table 1 provides detailed information about the assigned location, name, data, and time the photograph was taken along with links to the photograph. In addition to the photographs, a Google Earth Keyhole Markup Language (KML) file is provided and can be used to view the images by clicking on the marker and then clicking on either the thumbnail or the link above the thumbnail.
