Elevated concentrations of metals such as Cd, Cu, Fe, Mn, Ni, Pb, and Zn are observed in deionized water-based leachate solutions derived from complex sedex and Cu-Pb-Zn mine wastes. Leachate (USGS FLT) from the Elizabeth mine, a massive sulfide deposit, has a pH of 3.4 and high concentrations of Al (16700 ug/L), Cu (440 ug/L), and Zn (8620 ug/L). Leachate from the sedex Faro mine has a pH of 3.5 and high concentrations of Al (2040 ug/L), Cu (1930 ug/L), Pb (2080 ug/L), and Zn (52900 ug/L). In contrast, higher-pH leachates produced from tailings of polymetallic vein deposits have order of magnitude lower metal concentrations. These data indicate that highly soluble secondary mineral phases exist at the surface of waste material where the samples were collected. Sulfide minerals from all sites exhibit differential degrees of weathering, from dissolution etched grain rims, to rinds of secondary minerals, to skeletal remnants. These microscale mineral-dissolution textures enhance weathering and metal teachability of waste material. Besides the formation of secondary minerals, sulfide grains from dried tailings samples may be coated by amorphous Fe-Al-Si minerals that also adsorb metals such as Cu, Ni, and Zn.","largerWorkTitle":"SME Annual Meeting and Exhibit and CMA 113th National Western Mining Conference 2011","conferenceTitle":"SME Annual Meeting and Exhibit and CMA 113th National Western Mining Conference 2011","conferenceDate":"28 February 2011 through 2 March 2011","conferenceLocation":"Denver, CO","language":"English","isbn":"9781617829727","usgsCitation":"Diehl, S.F., Hageman, P., Seal, R., Piatak, N., and Lowers, H., 2011, Mineralogic sources of metals in leachates from the weathering of sedex, massive sulfide, and vein deposit mining wastes, <i>in</i> SME Annual Meeting and Exhibit and CMA 113th National Western Mining Conference 2011, Denver, CO, 28 February 2011 through 2 March 2011, p. 792-796.","startPage":"792","endPage":"796","numberOfPages":"5","ipdsId":"IP-026408","costCenters":[{"id":211,"text":"Crustal Geophysics and Geochemistry Science Center","active":true,"usgs":true}],"links":[{"id":246485,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a5a8de4b0c8380cd6ef63","contributors":{"authors":[{"text":"Diehl, S.

The aim of this work was to investigate how the composition of dissolved natural organic matter (NOM) influences the stability of zinc sulfide nanoparticles as they nucleate and aggregate in water with dissolved NOM. We compared NOM fractions that were isolated from several surface waters and represented a range of characteristics including molecular weight, type of carbon, and ligand density. Dynamic light scattering was employed to monitor the growth and aggregation of Zn−S−NOM nanoparticles in supersaturated solutions containing dissolved aquatic humic substances. The NOM was observed to reduce particle growth rates, depending on solution variables such as type and concentration of NOM, monovalent electrolyte concentration, and pH. The rates of growth increased with increasing ionic strength, indicating that observed growth rates primarily represented aggregation of charged Zn−S−NOM particles. Furthermore, the observed rates decreased with increasing molecular weight and aromatic content of the NOM fractions, while carboxylate and reduced sulfur content had little effect. Differences between NOM were likely due to properties that increased electrosteric hindrances for aggregation. Overall, results of this study suggest that the composition and source of NOM are key factors that contribute to the stabilization and persistence of zinc sulfide nanoparticles in the aquatic environment.</span></p>","language":"English","publisher":"ACS","doi":"10.1021/es1029798","usgsCitation":"Deonarine, A., Lau, B., Aiken, G.R., Ryan, J.N., and Hsu-Kim, H., 2011, Effects of humic substances on precipitation and aggregation of zinc sulfide nanoparticles: Environmental Science & Technology, v. 45, no. 8, p. 3217-3223, https://doi.org/10.1021/es1029798.","productDescription":"7 p.","startPage":"3217","endPage":"3223","costCenters":[{"id":145,"text":"Branch of Regional Research-Central Region","active":false,"usgs":true},{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":244536,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"45","issue":"8","noUsgsAuthors":false,"publicationDate":"2011-02-03","publicationStatus":"PW","scienceBaseUri":"505a071be4b0c8380cd5156d","contributors":{"authors":[{"text":"Deonarine, Amrika adeonarine@usgs.gov","contributorId":5072,"corporation":false,"usgs":true,"family":"Deonarine","given":"Amrika","email":"adeonarine@usgs.gov","affiliations":[{"id":241,"text":"Eastern Energy Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":443532,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lau, Boris","contributorId":62287,"corporation":false,"usgs":false,"family":"Lau","given":"Boris","email":"","affiliations":[{"id":12643,"text":"Duke University","active":true,"usgs":false}],"preferred":false,"id":443530,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Aiken, George R. 0000-0001-8454-0984 graiken@usgs.gov","orcid":"https://orcid.org/0000-0001-8454-0984","contributorId":1322,"corporation":false,"usgs":true,"family":"Aiken","given":"George","email":"graiken@usgs.gov","middleInitial":"R.","affiliations":[{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true},{"id":191,"text":"Colorado Water Science Center","active":true,"usgs":true}],"preferred":true,"id":443529,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Ryan, Joseph N.","contributorId":54290,"corporation":false,"usgs":false,"family":"Ryan","given":"Joseph","email":"","middleInitial":"N.","affiliations":[{"id":604,"text":"University of Colorado- Boulder","active":false,"usgs":true}],"preferred":false,"id":443533,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Hsu-Kim, Heileen","contributorId":49041,"corporation":false,"usgs":false,"family":"Hsu-Kim","given":"Heileen","affiliations":[{"id":12643,"text":"Duke University","active":true,"usgs":false}],"preferred":false,"id":443531,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Two processes consume sulfate at and above the SMT, anaerobic oxidation of methane (AOM) and organoclastic sulfate reduction (OSR). Differentiating the relative contribution of each process is critical to estimate methane flux into the SMT, which, in turn, is necessary to predict deeper occurrences of gas hydrates in continental margin sediments. To evaluate the relative importance of these two sulfate reduction pathways, we developed a diagenetic model to compute the pore water concentrations of sulfate, methane, and dissolved inorganic carbon (DIC).

Without AOM, methane diffuses above the SMT, which contradicts existing field data. The modeling results are generalized with a dimensional analysis to the range of SMT depths and sedimentation rates typical of continental margins.

Exported records for two aquatic rhabdovirus species emerging in North America were used in the implementation of two separate web-accessible databases: the Molecular Epidemiology of Aquatic Pathogens infectious haematopoietic necrosis virus (MEAP-IHNV) database (http://gis.nacse.org/ihnv/) released in 2006 and the MEAP- viral haemorrhagic septicaemia virus (http://gis.nacse.org/vhsv/) database released in 2010.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Fish Diseases","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Blackwell Publishing, Ltd.","doi":"10.1111/j.1365-2761.2011.01270.x","issn":"01407775","usgsCitation":"Emmenegger, E., Kentop, E., Thompson, T., Pittam, S., Ryan, A., Keon, D., Carlino, J., Ranson, J., Life, R., Troyer, R., Garver, K., and Kurath, G., 2011, Development of an aquatic pathogen database (AquaPathogen X) and its utilization in tracking emerging fish virus pathogens in North America: Journal of Fish Diseases, v. 34, no. 8, p. 579-587, https://doi.org/10.1111/j.1365-2761.2011.01270.x.","productDescription":"9 p.","startPage":"579","endPage":"587","costCenters":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"links":[{"id":216344,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1365-2761.2011.01270.x"},{"id":244208,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"34","issue":"8","noUsgsAuthors":false,"publicationDate":"2011-07-18","publicationStatus":"PW","scienceBaseUri":"505a004ee4b0c8380cd4f6c1","contributors":{"authors":[{"text":"Emmenegger, E.J.","contributorId":7463,"corporation":false,"usgs":true,"family":"Emmenegger","given":"E.J.","email":"","affiliations":[],"preferred":false,"id":451816,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kentop, E.","contributorId":84186,"corporation":false,"usgs":true,"family":"Kentop","given":"E.","email":"","affiliations":[],"preferred":false,"id":451823,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Thompson, T.M.","contributorId":32008,"corporation":false,"usgs":true,"family":"Thompson","given":"T.M.","email":"","affiliations":[],"preferred":false,"id":451817,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Pittam, S.","contributorId":97738,"corporation":false,"usgs":true,"family":"Pittam","given":"S.","email":"","affiliations":[],"preferred":false,"id":451824,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Ryan, A.","contributorId":68133,"corporation":false,"usgs":true,"family":"Ryan","given":"A.","email":"","affiliations":[],"preferred":false,"id":451821,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Keon, D.","contributorId":101488,"corporation":false,"usgs":true,"family":"Keon","given":"D.","email":"","affiliations":[],"preferred":false,"id":451827,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Carlino, J.A.","contributorId":70209,"corporation":false,"usgs":true,"family":"Carlino","given":"J.A.","email":"","affiliations":[],"preferred":false,"id":451822,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Ranson, J.","contributorId":97739,"corporation":false,"usgs":true,"family":"Ranson","given":"J.","affiliations":[],"preferred":false,"id":451825,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Life, R.B.","contributorId":41242,"corporation":false,"usgs":true,"family":"Life","given":"R.B.","email":"","affiliations":[],"preferred":false,"id":451818,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Troyer, R.M.","contributorId":63592,"corporation":false,"usgs":true,"family":"Troyer","given":"R.M.","email":"","affiliations":[],"preferred":false,"id":451820,"contributorType":{"id":1,"text":"Authors"},"rank":10},{"text":"Garver, K.A.","contributorId":42766,"corporation":false,"usgs":true,"family":"Garver","given":"K.A.","email":"","affiliations":[],"preferred":false,"id":451819,"contributorType":{"id":1,"text":"Authors"},"rank":11},{"text":"Kurath, Gael 0000-0003-3294-560X gkurath@usgs.gov","orcid":"https://orcid.org/0000-0003-3294-560X","contributorId":100522,"corporation":false,"usgs":true,"family":"Kurath","given":"Gael","email":"gkurath@usgs.gov","affiliations":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"preferred":true,"id":451826,"contributorType":{"id":1,"text":"Authors"},"rank":12}]}}

To flourish, maize needs water, sunlight (heat), and nutrients (e. g., nitrogen). In this paper, climate and soil chemistry data are used to evaluate the potential for dryland (rainon-field) agriculture in the semiarid southeastern Colorado Plateau and Rio Grande regions. Processes that impact maize agriculture such as nitrogen mineralization, infiltration of precipitation, bare soil evaporation, and transpiration are discussed and evaluated. Most of the study area, excepting high-elevation regions, receives sufficient solar radiation to grow maize. The salinities of subsurface soils in the central San Juan Basin are very high and their nitrogen concentrations are very low. In addition, soils of the central San Juan Basin are characterized by pH values that exceed 8.0, which limit the availability of both nitrogen and phosphorous. In general, the San Juan Basin, including Chaco Canyon, is the least promising part of the study area in terms of dryland farming. Calculations of field life, using values of organic nitrogen for the upper 50 cm of soil in the study area, indicate that most of the study area could not support a 10-bushel/acre crop of maize. The concepts, methods, and calculations used to quantify maize productivity in this study are applicable to maize cultivation in other environmental settings across the Americas. ?? 2010 US Government.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Archaeological Method and Theory","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1007/s10816-010-9082-z","issn":"10725369","usgsCitation":"Benson, L.V., 2011, Factors Controlling Pre-Columbian and Early Historic Maize Productivity in the American Southwest, Part 1: The Southern Colorado Plateau and Rio Grande Regions: Journal of Archaeological Method and Theory, v. 18, no. 1, p. 1-60, https://doi.org/10.1007/s10816-010-9082-z.","startPage":"1","endPage":"60","numberOfPages":"60","costCenters":[],"links":[{"id":216864,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10816-010-9082-z"},{"id":244762,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"18","issue":"1","noUsgsAuthors":false,"publicationDate":"2010-05-18","publicationStatus":"PW","scienceBaseUri":"505a0e97e4b0c8380cd53524","contributors":{"authors":[{"text":"Benson, L.

The mesas may be analogous to terrestrial tuyas (emergent sub-ice volcanoes), although definitive proof has not been identified. We also report on a blocky unit and associated landforms (drumlins, eskers, inverted valleys, kettle holes) consistent with ice-emplaced volcanic or volcano-sedimentary flows. The spatial association between tuya-like mesas, ice-emplaced flows, and further possible evidence of volcanism (deflated flow fronts, volcanic vents, columnar jointing, rootless cones), and an extensive fluid-rich substratum (giant polygons, bright mounds, rampart craters), allows for the possibility of glaciovolcanic activity in the region.Landforms indicative of glacial activity on Chryse/Acidalia suggest a paleoclimatic environment remarkably different from today's.

The efficiency of block-structured AMR makes large-scale problems tractable, and allows the use of accurate and stable methods developed for solving general hyperbolic problems on quadrilateral grids. Features indicative of flooding in rugged terrain, such as advancing wet-dry fronts and non-stationary steady states due to balanced source terms from variable topography, present unique challenges and require modifications such as special Riemann solvers. A well-balanced Riemann solver for inundation and general (non-stationary) flow over topography is tested in this context. The difficulties of modeling floods in rugged terrain, and the rationale for and efficacy of using AMR and well-balanced methods, are presented. The algorithms are validated by simulating the Malpasset dam-break flood (France, 1959), which has served as a benchmark problem previously. Historical field data, laboratory model data and other numerical simulation results (computed on static fitted meshes) are shown for comparison. The methods are implemented in GEOCLAW, a subset of the open-source CLAWPACK software. All the software is freely available at.

Using this method, all six inorganic species can be determined in less than 3&nbsp;min. A dynamic reaction cell (DRC)–ICP-MS system was used to detect the species eluted from the chromatographic column in order to reduce interferences. A variety of reaction cell gases and conditions may be utilized with the DRC–ICP-MS, and final selection of conditions is determined by data quality objectives. Results indicated all starting standards, reagents, and sample vials should be thoroughly tested for contamination. Tests on species stability indicated that refrigeration at 10&nbsp;°C was preferential to freezing for most species, particularly when all species were present, and that sample solutions and extracts should be analyzed as soon as possible to eliminate species instability and interconversion effects. A variety of environmental and geological samples, including waters and deionized water [leachates] and simulated biological leachates from soils and wildfire ashes have been analyzed using this method. Analytical spikes performed on each sample were used to evaluate data quality. Speciation analyses were conducted on deionized water leachates and simulated lung fluid leachates of ash and soils impacted by wildfires. These results show that, for leachates containing high levels of total Cr, the majority of the chromium was present in the hexavalent Cr(VI) form. In general, total and hexavalent chromium levels for samples taken from burned residential areas were higher than those obtained from non-residential forested areas. Arsenic, when found, was generally in the more oxidized As(V) form.

Various ground-based and remotely sensed methods are used to measure and map subsidence. Many areas of subsidence caused by groundwater pumping have been identified and monitored, and corrective measures to slow or halt subsidence have been devised. Two principal means are used to mitigate subsidence caused by groundwater withdrawal—reduction of groundwater withdrawal, and artificial recharge. Analysis and simulation of aquifer-system compaction follow from the basic relations between head, stress, compressibility, and groundwater flow and are addressed primarily using two approaches—one based on conventional groundwater flow theory and one based on linear poroelasticity theory. Research and development to improve the assessment and analysis of aquifer-system compaction, the accompanying subsidence and potential ground ruptures are needed in the topic areas of the hydromechanical behavior of aquitards, the role of horizontal deformation, the application of differential synthetic aperture radar interferometry, and the regional-scale simulation of coupled groundwater flow and aquifer-system deformation to support resource management and hazard mitigation measures.","language":"English, French, Spanish","publisher":"Springer","doi":"10.1007/s10040-011-0775-5","issn":"14312174","usgsCitation":"Galloway, D.L., and Burbey, T.J., 2011, Review: Regional land subsidence accompanying groundwater extraction: Hydrogeology Journal, v. 19, no. 8, p. 1459-1486, https://doi.org/10.1007/s10040-011-0775-5.","productDescription":"28 p.","startPage":"1459","endPage":"1486","costCenters":[{"id":35860,"text":"Ohio-Kentucky-Indiana Water Science Center","active":true,"usgs":true}],"links":[{"id":243729,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":215894,"rank":2,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10040-011-0775-5"}],"volume":"19","issue":"8","noUsgsAuthors":false,"publicationDate":"2011-08-26","publicationStatus":"PW","scienceBaseUri":"505aaca3e4b0c8380cd86d8b","contributors":{"authors":[{"text":"Galloway, Devin L. 0000-0003-0904-5355 dlgallow@usgs.gov","orcid":"https://orcid.org/0000-0003-0904-5355","contributorId":679,"corporation":false,"usgs":true,"family":"Galloway","given":"Devin","email":"dlgallow@usgs.gov","middleInitial":"L.","affiliations":[{"id":35860,"text":"Ohio-Kentucky-Indiana Water Science Center","active":true,"usgs":true},{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true},{"id":5058,"text":"Office of the Chief Scientist for Water","active":true,"usgs":true},{"id":5078,"text":"Southwest Regional Director's Office","active":true,"usgs":true},{"id":509,"text":"Office of the Associate Director for Water","active":true,"usgs":true}],"preferred":true,"id":446846,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Burbey, Thomas J.","contributorId":51770,"corporation":false,"usgs":true,"family":"Burbey","given":"Thomas","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":446847,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Daily discharge and suspended sediment export from two 5,000-ha watersheds in central Iowa were monitored over a 10-year period (water years 1996-2005). In Walnut Creek watershed, a large portion of land was converted from row crop to native prairie, whereas in Squaw Creek land use remained predominantly row crop agriculture. Suspended sediment loads were similar in both watersheds, exhibiting flashy behavior typical of incised channels. Modeling suggested that expected total soil erosion in Walnut Creek should have been reduced 46% relative to Squaw Creek due to changes in land use, yet measured suspended sediment loads showed no significant differences. Stream mapping indicated that Walnut Creek had three times more eroding streambank lengths than did Squaw Creek suggesting that streambank erosion dominated sediment sources in Walnut Creek and sheet and rill sources dominated sediment sources in Squaw Creek. Our results demonstrate that an accounting of all sources of sediment erosion and delivery is needed to characterize sediment reductions in watershed projects combined with long-term, intensive monitoring and modeling to account for possible lag times in the manifestation of the benefits of conservation practices on water quality.</p>","language":"English","publisher":"American Water Resources Association","doi":"10.1111/j.1752-1688.2011.00533.x","issn":"1093474X","usgsCitation":"Schilling, K.E., Isenhart, T., Palmer, J., Wolter, C., and Spooner, J., 2011, Impacts of Land-Cover Change on Suspended Sediment Transport in Two Agricultural Watersheds: Journal of the American Water Resources Association, v. 47, no. 4, p. 672-686, https://doi.org/10.1111/j.1752-1688.2011.00533.x.","productDescription":"15 p.","startPage":"672","endPage":"686","costCenters":[],"links":[{"id":245540,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":217587,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1752-1688.2011.00533.x"}],"country":"United States","state":"Iowa","county":"Jasper","otherGeospatial":"Walnut and Squaw Creek","geographicExtents":"{\"type\":\"FeatureCollection\",\"features\":[{\"type\":\"Feature\",\"geometry\":{\"type\":\"Polygon\",\"coordinates\":[[[-93.234,41.8622],[-93.1187,41.8624],[-93.0035,41.8624],[-92.8845,41.8619],[-92.7674,41.8618],[-92.7683,41.776],[-92.768,41.6879],[-92.7683,41.6007],[-92.7567,41.6011],[-92.7564,41.509],[-92.8729,41.5082],[-92.9894,41.5083],[-93.1047,41.5078],[-93.2181,41.5076],[-93.3304,41.5074],[-93.3314,41.6004],[-93.3504,41.6004],[-93.3496,41.688],[-93.3494,41.7757],[-93.3492,41.8624],[-93.234,41.8622]]]},\"properties\":{\"name\":\"Jasper\",\"state\":\"IA\"}}]}","volume":"47","issue":"4","noUsgsAuthors":false,"publicationDate":"2011-03-30","publicationStatus":"PW","scienceBaseUri":"505a38dde4b0c8380cd616fb","contributors":{"authors":[{"text":"Schilling, K.

The models were standardized to reflect nutrient sources and stream conditions during 2002. Model predictions of nutrient loads (mass per time) and yields (mass per area per time) generally were greatest in streams in the eastern part of the region and along reaches near the Texas and Louisiana shoreline. The Mississippi River and Atchafalaya River watersheds, which drain nearly two‐thirds of the conterminous U.S., delivered the largest nutrient loads to the Gulf of Mexico, as expected. However, the three largest delivered TN yields were from the Trinity River/Galveston Bay, Calcasieu River, and Aransas River watersheds, while the three largest delivered TP yields were from the Calcasieu River, Mermentau River, and Trinity River/Galveston Bay watersheds. Model output indicated that the three largest sources of nitrogen from the region were atmospheric deposition (42%), commercial fertilizer (20%), and livestock manure (unconfined, 17%).

The surveys extended from water depths of 4 m to 22 m and covered an area of 3.14 km2, 45.8% of which was bedrock, gravel, and coarse-grained sand and 54.2% was fine-grained sand. Our analyses of the bathymetric and acoustic backscatter data demonstrates that during the 6 months between surveys, 11.4% of the study area was buried by fine-grained sand while erosion resulted in the exposure of bedrock or coarse-grained sand over 26.5% of the study area. The probability of burial decreased with increasing water depth and rugosity; the probability of exhumation increased with increasing wave-induced near-bed shear stress, seabed slope and rugosity. Much of the detected change was at the boundary between bedrock and unconsolidated sediment due to sedimentation and erosion burying or exhuming bedrock, respectively. In a number of cases, however, the change in seabed character was apparently due to changes in sediment grain size when scour exposed what appeared to be an underlying coarser-grained lag or the burial of coarser-grained sand and gravel by fine-grained sand. These findings suggest that, in some places, (a) burial and exhumation of nearshore bedrock reefs along rocky, energetic inner shelves occurs over seasonal timescales and appears related to intrinsic factors such as seabed morphology and extrinsic factors such as wave forces, and (b) single acoustic surveys typically employed for geologic characterization and/or habitat mapping may not adequately characterize the geomorphologic and sedimentologic nature of these types of environments that typify most of the Pacific Ocean and up to 50% of the world's coastlines.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Marine Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.margeo.2011.09.010","issn":"00253227","usgsCitation":"Storlazzi, C., Fregoso, T., Golden, N., and Finlayson, D., 2011, Sediment dynamics and the burial and exhumation of bedrock reefs along an emergent coastline as elucidated by repetitive sonar surveys: Northern Monterey Bay, CA: Marine Geology, v. 289, no. 1-4, p. 46-59, https://doi.org/10.1016/j.margeo.2011.09.010.","productDescription":"14 p.","startPage":"46","endPage":"59","costCenters":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":215660,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.margeo.2011.09.010"},{"id":243479,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"state":"California","otherGeospatial":"Monterey Bay","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -122.145,36.629 ], [ -122.145,36.941 ], [ -121.828,36.941 ], [ -121.828,36.629 ], [ -122.145,36.629 ] ] ] } } ] }","volume":"289","issue":"1-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b8988e4b08c986b316e10","contributors":{"authors":[{"text":"Storlazzi, C.

In the present paper, Pb isotope ratios have been used to determine the sources of metal pollution in soils and waters in the Agro Aversano area. During three different sampling phases, a total of 113 surface soils (5-20. cm), 20 samples from 2 soil profiles (0-1. m), 11 stream waters and 4 groundwaters were collected. Major element concentrations in sampled media have been analyzed by the ICP-MS technique. Surface soils (20 samples), all soil profiles and all waters have been also analyzed for Pb isotope compositions by thermal ionization (TIMS). The geochemical data were assessed using statistic methods and cartographically elaborated in order to have a clear picture of the level of disturbance of the area. Pb isotopic data were studied to discriminate between anthropogenic and geologic sources. Our results show that As (5.6-25.6. mg/kg), Cu (9-677. mg/kg), Pb (22-193. mg/kg), Tl (0.53-3.62. mg/kg), V (26-142. mg/kg) and Zn (34-215. mg//kg) contents in analyzed soils, exceed the intervention limits fixed by the Italian Environmental Law for residential areas in some of the sampled sites, while intervention limit for industrial areas is exceeded only for Cu concentrations. Lead isotopic data, show that there is a high similarity between the ratios measured in the leached soil samples and those deriving from anthropic activities. This similarity with anthropogenic Pb is also evident in the ratios measured in both groundwater and stream water samples. ?? 2010 Elsevier B.V.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Geochemical Exploration","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.gexplo.2010.09.013","issn":"03756742","usgsCitation":"Bove, M., Ayuso, R., de Vivo, B., Lima, A., and Albanese, S., 2011, Geochemical and isotopic study of soils and waters from an Italian contaminated site: Agro Aversano (Campania): Journal of Geochemical Exploration, v. 109, no. 1-3, p. 38-50, https://doi.org/10.1016/j.gexplo.2010.09.013.","startPage":"38","endPage":"50","numberOfPages":"13","costCenters":[],"links":[{"id":244809,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":216908,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.gexplo.2010.09.013"}],"volume":"109","issue":"1-3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a15d8e4b0c8380cd54f74","contributors":{"authors":[{"text":"Bove, M.A.","contributorId":49211,"corporation":false,"usgs":true,"family":"Bove","given":"M.A.","email":"","affiliations":[],"preferred":false,"id":444574,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Ayuso, R.

A diverse set of 42 floodplain lakes in the Yazoo River Basin (Mississippi, USA) was examined to test the hypothesis of whether depth reduction was a key determinant of water quality and fish assemblage structure. Single and multiple variable analyses were applied to 10 commonly monitored water variables and 54 fish species. Results showed strong associations between depth and water characteristics, and between depth and fish assemblages. Deep lakes provided less variable environments, clearer water, and a wider range of microhabitats than shallow lakes. The greater environmental stability was reflected by the dominant species in the assemblages, which included a broader representation of large-body species, species less tolerant of extreme water quality, and more predators. Stability in deep lakes was further reflected by reduced among-lake variability in taxa representation. Fish assemblages in shallow lakes were more variable than deep lakes, and commonly dominated by opportunistic species that have early maturity, extended breeding seasons, small adult size, and short lifespan. Depth is a causal factor that drives many physical and chemical variables that contribute to organizing fish assemblages in floodplain lakes. Thus, correlations between fish and water transparency, temperature, oxygen, trophic state, habitat structure, and other environmental descriptors may ultimately be totally or partly regulated by depth. In basins undergoing rapid anthropogenic modifications, local changes forced by depth reductions may be expected to eliminate species available from the regional pool and could have considerable ecological implications.</span></p>","language":"English","publisher":"Springer Link","doi":"10.1007/s00027-010-0170-7","issn":"10151621","usgsCitation":"Miranda, L.E., 2011, Depth as an organizer of fish assemblages in floodplain lakes: Aquatic Sciences, v. 73, no. 2, p. 211-221, https://doi.org/10.1007/s00027-010-0170-7.","productDescription":"11 p.","startPage":"211","endPage":"221","ipdsId":"IP-021899","costCenters":[{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true}],"links":[{"id":243804,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":215967,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s00027-010-0170-7"}],"country":"United States","state":"Mississippi","otherGeospatial":"Yazoo River Basin","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -90.98876953125,\n              32.43561304116276\n            ],\n            [\n              -90.3076171875,\n              32.63937487360669\n            ],\n            [\n              -89.6484375,\n              32.89803818160521\n            ],\n            [\n              -88.9892578125,\n              34.14363482031264\n            ],\n            [\n              -88.83544921874999,\n              35.0120020431607\n            ],\n            [\n              -90.2197265625,\n              34.994003757575776\n            ],\n            [\n              -90.5712890625,\n              34.75966612466248\n            ],\n            [\n              -91.03271484375,\n              34.08906131584994\n            ],\n            [\n              -91.29638671875,\n              33.52307880890422\n            ],\n            [\n              -91.1865234375,\n              32.565333160841035\n            ],\n            [\n              -90.98876953125,\n              32.43561304116276\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"73","issue":"2","noUsgsAuthors":false,"publicationDate":"2010-11-09","publicationStatus":"PW","scienceBaseUri":"5059fecee4b0c8380cd4ef34","contributors":{"authors":[{"text":"Miranda, Leandro E. 0000-0002-2138-7924 smiranda@usgs.gov","orcid":"https://orcid.org/0000-0002-2138-7924","contributorId":531,"corporation":false,"usgs":true,"family":"Miranda","given":"Leandro","email":"smiranda@usgs.gov","middleInitial":"E.","affiliations":[{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true}],"preferred":true,"id":448236,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Aerial imagery and field data collected in the nesting season were the primary sources of data. From 1993/1994 to 2007/2008, a group of 15 islands in Tangier Sound, Virginia were reduced by 21% in area, as most of their small dunes and associated vegetation and forest cover were lost to increased washovers.

Our results provide support for a physico-chemical model of coral biomineralization, and imply that Mg2+ substitutes directly for Ca2+ in biogenic aragonite. Recent studies have identified Rayleigh fractionation as an important influence on the elemental composition of coral skeletons. Daily, seasonal and interannual variations in the amount of aragonite precipitated by corals from each “batch” of calcifying fluid can explain why the temperature dependencies of elemental ratios in coral skeleton differ from those of abiogenic aragonites, and are highly variable among individual corals. On the basis of this new insight into the origin of “vital effects” in coral skeleton, we developed a Rayleigh-based, multi-element approach to coral thermometry. Temperature is resolved from the Rayleigh fractionation signal by combining information from multiple element ratios (e.g., Mg/Ca, Sr/Ca, Ba/Ca) to produce a mathematically over-constrained system of Rayleigh equations. Unlike conventional coral thermometers, this approach does not rely on an initial calibration of coral skeletal composition to an instrumental temperature record. Rather, considering coral skeletogenesis as a biologically mediated, physico-chemical process provides a means to extract temperature information from the skeleton composition using the Rayleigh equation and a set of experimentally determined partition coefficients. Because this approach is based on a quantitative understanding of the mechanism that produces the “vital effect” it should be possible to apply it both across scleractinian species and to corals growing in vastly different environments. Where instrumental temperature records are available, a Rayleigh-based framework allows the effects of stress on coral calcification to be identified on the basis of anomalies in the skeletal composition.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geochimica et Cosmochimica Acta","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.gca.2011.01.010","issn":"00167037","usgsCitation":"Gaetani, G., Cohen, A., Wang, Z., and Crusius, J., 2011, Rayleigh-based, multi-element coral thermometry: A biomineralization approach to developing climate proxies: Geochimica et Cosmochimica Acta, v. 75, no. 7, p. 1920-1932, https://doi.org/10.1016/j.gca.2011.01.010.","productDescription":"13 p.","startPage":"1920","endPage":"1932","costCenters":[{"id":680,"text":"Woods Hole Science Center","active":false,"usgs":true}],"links":[{"id":243834,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":215995,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.gca.2011.01.010"}],"volume":"75","issue":"7","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a955be4b0c8380cd81979","contributors":{"authors":[{"text":"Gaetani, G.A.","contributorId":77763,"corporation":false,"usgs":true,"family":"Gaetani","given":"G.A.","affiliations":[],"preferred":false,"id":448246,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Cohen, A.L.","contributorId":68131,"corporation":false,"usgs":true,"family":"Cohen","given":"A.L.","email":"","affiliations":[],"preferred":false,"id":448245,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Wang, Z.","contributorId":67976,"corporation":false,"usgs":true,"family":"Wang","given":"Z.","affiliations":[],"preferred":false,"id":448244,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Crusius, John 0000-0003-2554-0831 jcrusius@usgs.gov","orcid":"https://orcid.org/0000-0003-2554-0831","contributorId":2155,"corporation":false,"usgs":true,"family":"Crusius","given":"John","email":"jcrusius@usgs.gov","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":119,"text":"Alaska Science Center Geology Minerals","active":true,"usgs":true}],"preferred":true,"id":448243,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Although studies in freshwater ecosystems have received recent attention, research has rarely considered the potential trade-offs between protecting different dimensions of biodiversity and the ecological processes that maintain diversity. We provide the first systematic prioritization for freshwaters (focusing on the highly threatened and globally distinct fish fauna of the Lower Colorado River Basin, USA) simultaneously considering scenarios of: taxonomic, functional, and phylogenetic diversity; contemporary threats to biodiversity (including interactions with nonnative species); and future climate change and human population growth. There was 75% congruence between areas of highest conservation priority for different aspects of biodiversity, suggesting that conservation efforts can concurrently achieve strong complementarity among all types of diversity. However, sizable fractions of the landscape were incongruent across conservation priorities for different diversity scenarios, underscoring the importance of considering multiple dimensions of biodiversity and highlighting catchments that contribute disproportionately to taxonomic, functional, and phylogenetic diversity in the region. Regions of projected human population growth were not concordant with conservation priorities; however, higher human population abundance will likely have indirect effects on native biodiversity by increasing demand for water. This will come in direct conflict with projected reductions in precipitation and warmer temperatures, which have substantial overlap with regions of high contemporary diversity. Native and endemic fishes in arid ecosystems are critically endangered by both current and future threats, but our results highlight the use of systematic conservation planning for the optimal allocation of limited resources that incorporates multiple and complementary conservation values describing taxonomic, functional, and phylogenetic diversity.</span></p>","language":"English","publisher":"Ecological Society of America","doi":"10.1890/11-0599.1","usgsCitation":"Strecker, A.L., Olden, J., Whittier, J.B., and Paukert, C.P., 2011, Defining conservation priorities for freshwater fishes according to taxonomic, functional, and phylogenetic diversity: Ecological Applications, v. 21, no. 8, p. 3002-3013, https://doi.org/10.1890/11-0599.1.","productDescription":"12 p.","startPage":"3002","endPage":"3013","costCenters":[{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true},{"id":411,"text":"National Climate Change and Wildlife Science Center","active":true,"usgs":true}],"links":[{"id":242879,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"21","issue":"8","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059fe37e4b0c8380cd4ebcf","contributors":{"authors":[{"text":"Strecker, A.

A major concern is the elevated concentration of long-lived 226Ra (half-life = 1,600 years) inherited from the processed phosphate rock. Knowledge of the abundance and mode-of-occurrence of radium (Ra) in PG is critical for accurate prediction of Ra leachability and radon (Rn) emanation, and for prediction of radiation-exposure pathways to workers and to the public. The mean (??SD) of 226Ra concentrations in ten samples of Jordan PG is 601 ?? 98 Bq/kg, which falls near the midrange of values reported for PG samples collected worldwide. Jordan PG generally shows no analytically significant enrichment (&lt; 10%) of 226Ra in the finer (&lt; 53 ??m) grain size fraction. Phosphogypsum samples collected from two industrial sites with different sources of phosphate rock feedstock show consistent differences in concentration of 226Ra and rare earth elements, and also consistent trends of enrichment in these elements with increasing age of PG. Water-insoluble residues from Jordan PG constitute &lt;10% of PG mass but contain 30-65% of the 226Ra. 226Ra correlates closely with Ba in the water-insoluble residues. Uniformly tiny (&lt; 10 ??m) grains of barite (barium sulfate) observed with scanning electron microscopy have crystal morphologies that indicate their formation during the wet process.

Different patterns of re-entrainment were evident for the two colloids in response to subsequent injections of groundwater (hydrodynamic perturbation), deionized water (ionic strength alteration), 77 μM linear alkylbenzene sulfonates (LAS, anionic surfactant), and 76 μM Tween 80 (polyoxyethylene sorbitan monooleate, a very hydrophobic nonionic surfactant). An injection of deionized water was more effective in causing detachment of micrsopheres than were either of the surfactants, consistent with the more electrostatic nature of microsphere’s attachment, their extreme hydrophilicity (hydrophilicity index, HI, of 0.99), and negative charge (zeta potentials, ζ, of −44 to −49 mv). In contrast, Tween 80 was considerably more effective in re-entraining the more-hydrophobic native bacteria. Both the hydrophilicities and zeta potentials of the native bacteria were highly sensitive to and linearly correlated with levels of groundwater dissolved organic carbon (DOC), which varied modestly from 0.6 to 1.3 mg L<sup>−1</sup>. The most hydrophilic (0.52 HI) and negatively charged (ζ −38.1 mv) indigenous bacteria were associated with the lowest DOC. FTIR spectra indicated the latter community had the highest average density of surface carboxyl groups. In contrast, differences in groundwater (DOC) had no measurable effect on hydrophilicity of the bacteria-sized microspheres and only a minor effect on their ζ. These findings suggest that microspheres may not be very good surrogates for bacteria in field-scale transport studies and that adaptive (biological) changes in bacterial surface characteristics may need to be considered where there is longer-term exposure to contaminant DOC.</p>","language":"English","publisher":"ACS","doi":"10.1021/es102989x","issn":"0013936X","usgsCitation":"Harvey, R.W., Metge, D., Mohanram, A., Gao, X., and Chorover, J., 2011, Differential effects of dissolved organic carbon upon re-entrainment and surface properties of groundwater bacteria and bacteria-sized microspheres during transport through a contaminated, sandy aquifer: Environmental Science & Technology, v. 45, no. 8, p. 3252-3259, https://doi.org/10.1021/es102989x.","productDescription":"8 p.
