Four sites were investigated on Long Island, New York, characterized by groundwater contaminated with gasoline and fuel oxygenates that ultimately discharge to fresh, brackish, or saline surface water. For each site, contaminated groundwater discharge zones were delineated using pore water geochemistry data from 15 feet (4.5 m) beneath the bottom of the surface water body in the hyporheic zone and seepage-meter tests were conducted to measure discharge rates. These data when combined indicate that MTBE, TBA, and TAME concentrations in groundwater discharge in a 5-foot (1.5-m) thick section of the hyporheic zone were attenuated between 34% and 95%, in contrast to immeasurable attenuation in the shallow aquifer during contaminant transport between 0.1 and 1.5 miles (0.1 to 2.4 km). The attenuation observed in the hyporheic zone occurred primarily by physical processes such as mixing of groundwater and surface water. Biodegradation also occurred as confirmed in laboratory microcosms by the mineralization of U- <sup>14</sup>C-MTBE and U- <sup>14</sup>C-TBA to <sup>14</sup>CO<sub>2</sub> and the novel biodegradation of U- <sup>14</sup>C-TAME to <sup>14</sup>CO<sub>2</sub> under oxic and anoxic conditions. The implication of fuel oxygenate attenuation observed in diverse hyporheic zones suggests an assessment of the hyporheic zone attenuation potential (HZAP) merits inclusion as part of site assessment strategies associated with monitored or engineered attenuation.</p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ground Water","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1745-6584.2009.00608.x","issn":"0017467X","usgsCitation":"Landmeyer, J., Bradley, P.M., Trego, D., Hale, K., and Haas, J., 2010, MTBE, TBA, and TAME attenuation in diverse hyporheic zones: Ground Water, v. 48, no. 1, p. 30-41, https://doi.org/10.1111/j.1745-6584.2009.00608.x.","productDescription":"12 p.","startPage":"30","endPage":"41","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":241938,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":214238,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1745-6584.2009.00608.x"}],"volume":"48","issue":"1","noUsgsAuthors":false,"publicationDate":"2009-12-23","publicationStatus":"PW","scienceBaseUri":"505a4affe4b0c8380cd691fd","contributors":{"authors":[{"text":"Landmeyer, James 0000-0002-5640-3816 jlandmey@usgs.gov","orcid":"https://orcid.org/0000-0002-5640-3816","contributorId":3257,"corporation":false,"usgs":true,"family":"Landmeyer","given":"James","email":"jlandmey@usgs.gov","affiliations":[{"id":13634,"text":"South Atlantic Water Science Center","active":true,"usgs":true}],"preferred":true,"id":442870,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"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":442867,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Trego, D.A.","contributorId":66930,"corporation":false,"usgs":true,"family":"Trego","given":"D.A.","email":"","affiliations":[],"preferred":false,"id":442869,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hale, K.G.","contributorId":40436,"corporation":false,"usgs":true,"family":"Hale","given":"K.G.","email":"","affiliations":[],"preferred":false,"id":442868,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Haas, J.E.

The maxima of total particulate flux, which reached as high as 300+ g/m<sup>2</sup>/day in Hueneme Canyon, were recorded during winter storm events when high waves and river floods often coincided. During these winter storms, wave-induced resuspension of shelf sediment was a major source for the elevated sediment fluxes. Canyon rim morphology, rather than physical proximity to an adjacent river mouth, appeared to control the magnitude of sediment fluxes in these two submarine canyon systems. Episodic turbidity currents and internal bores enhanced sediment fluxes, particularly in the lower sediment traps positioned 30 m above the canyon floor. Lower excess <sup>210</sup>Pb activities measured in the sediment samples collected during periods of peak total particulate flux further substantiate that reworked shelf-, rather than newly introduced river-borne, sediments supply most of the material entering these canyons during storms.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Marine Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.margeo.2009.12.007","issn":"00253227","usgsCitation":"Xu, J.P., Swarzenski, P., Noble, M., and Li, A., 2010, Event-driven sediment flux in Hueneme and Mugu submarine canyons, southern California: Marine Geology, v. 269, no. 1-2, p. 74-88, https://doi.org/10.1016/j.margeo.2009.12.007.","productDescription":"15 p.","startPage":"74","endPage":"88","costCenters":[{"id":586,"text":"Tinker & Estes Lab and Santa Cruz Field Station","active":false,"usgs":true}],"links":[{"id":214321,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.margeo.2009.12.007"},{"id":242038,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"269","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0d23e4b0c8380cd52e2b","contributors":{"authors":[{"text":"Xu, J.

However, protected areas are only effective when they stop habitat loss within their boundaries, and are connected via corridors to other wild areas. The effectiveness of protected areas is threatened by development; however, the extent of this threat is unknown. We compiled spatially-detailed housing growth data from 1940 to 2030, and quantified growth for each wilderness area, national park, and national forest in the conterminous United States. Our findings show that housing development in the United States may severely limit the ability of protected areas to function as a modern \"Noah's Ark.\" Between 1940 and 2000, 28 million housing units were built within 50 km of protected areas, and 940,000 were built within national forests. Housing growth rates during the 1990s within 1 km of protected areas (20% per decade) outpaced the national average (13%). If long-term trends continue, another 17 million housing units will be built within 50 km of protected areas by 2030 (1 million within 1 km), greatly diminishing their conservation value. US protected areas are increasingly isolated, housing development in their surroundings is decreasing their effective size, and national forests are even threatened by habitat loss within their administrative boundaries. Protected areas in the United States are thus threatened similarly to those in developing countries. However, housing growth poses the main threat to protected areas in the United States whereas deforestation is the main threat in developing countries.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Proceedings of the National Academy of Sciences of the United States of America","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1073/pnas.0911131107","issn":"00278424","usgsCitation":"Radeloff, V.C., Stewart, S.I., Hawbaker, T., Gimmi, U., Pidgeon, A., Flather, C., Hammer, R.B., and Helmers, D., 2010, Housing growth in and near United States protected areas limits their conservation value: Proceedings of the National Academy of Sciences of the United States of America, v. 107, no. 2, p. 940-945, https://doi.org/10.1073/pnas.0911131107.","startPage":"940","endPage":"945","numberOfPages":"6","costCenters":[],"links":[{"id":487749,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://www.ncbi.nlm.nih.gov/pmc/articles/2818924","text":"External Repository"},{"id":214320,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1073/pnas.0911131107"},{"id":242037,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"107","issue":"2","noUsgsAuthors":false,"publicationDate":"2009-12-22","publicationStatus":"PW","scienceBaseUri":"505a3240e4b0c8380cd5e651","contributors":{"authors":[{"text":"Radeloff, V.

Catch rate varied with year, season and the diel period during which sampling was conducted as well as by the interaction between year and season. Indices of abundance of age-0 and age-1 yellow perch estimated from night samples typically produced better fitting models and lower estimates of age-2 abundance than those using morning or afternoon samples, whereas indices using afternoon samples typically produced less precise and higher estimates of abundance. The diel period during which sampling is conducted will not affect observed population trends but may affect estimates of abundance of age-0 and age-1 yellow perch, which in turn affect recommended allowable harvest.

We begin by using absolute arrival-time picks to solve for a coarse three-dimensional (3D) P velocity (V<sub>P</sub>) model with a uniform 30 km horizontal node spacing, which we then use as the starting model for a finer-scale inversion using double-difference tomography applied to absolute and differential pick times. For computational reasons, we split the state into 5 subregions with a grid spacing of 10 to 20 km and assemble our final statewide V<sub>P</sub> model by stitching together these local models. We also solve for a statewide S-wave model using S picks from both the Southern California Seismic Network and USArray, assuming a starting model based on the V<sub>P</sub> results and a V<sub>P</sub>=V<sub>S</sub> ratio of 1.732. Our new model has improved areal coverage compared with previous models, extending 570 km in the SW-NE directionand 1320 km in the NW-SE direction. It also extends to greater depth due to the inclusion of substantial data at large epicentral distances. Our V<sub>P</sub> model generally agrees with previous separate regional models for northern and southern California, but we also observe some new features, such as high-velocity anomalies at shallow depths in the Klamath Mountains and Mount Shasta area, somewhat slow velocities in the northern Coast Ranges, and slow anomalies beneath the Sierra Nevada at midcrustal and greater depths. This model can be applied to a variety of regional-scale studies in California, such as developing a unified statewide earthquake location catalog and performing regional waveform modeling.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Bulletin of the Seismological Society of America","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1785/0120090028","issn":"00371106","usgsCitation":"Lin, G., Thurber, C., Zhang, H., Hauksson, E., Shearer, P., Waldhauser, F., Brocher, T., and Hardebeck, J., 2010, A California statewide three-dimensional seismic velocity model from both absolute and differential times: Bulletin of the Seismological Society of America, v. 100, no. 1, p. 225-240, https://doi.org/10.1785/0120090028.","startPage":"225","endPage":"240","numberOfPages":"16","costCenters":[],"links":[{"id":476100,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://resolver.caltech.edu/CaltechAUTHORS:20100303-135921624","text":"External Repository"},{"id":214261,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1785/0120090028"},{"id":241966,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"100","issue":"1","noUsgsAuthors":false,"publicationDate":"2010-01-27","publicationStatus":"PW","scienceBaseUri":"5059e2cbe4b0c8380cd45c61","contributors":{"authors":[{"text":"Lin, G.","contributorId":108325,"corporation":false,"usgs":true,"family":"Lin","given":"G.","email":"","affiliations":[],"preferred":false,"id":442528,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Thurber, C.H.","contributorId":28617,"corporation":false,"usgs":true,"family":"Thurber","given":"C.H.","email":"","affiliations":[],"preferred":false,"id":442522,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Zhang, H.","contributorId":50311,"corporation":false,"usgs":true,"family":"Zhang","given":"H.","affiliations":[],"preferred":false,"id":442524,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hauksson, E.","contributorId":10932,"corporation":false,"usgs":true,"family":"Hauksson","given":"E.","affiliations":[],"preferred":false,"id":442521,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Shearer, P.M.","contributorId":80456,"corporation":false,"usgs":true,"family":"Shearer","given":"P.M.","email":"","affiliations":[],"preferred":false,"id":442526,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Waldhauser, F.","contributorId":31897,"corporation":false,"usgs":true,"family":"Waldhauser","given":"F.","affiliations":[],"preferred":false,"id":442523,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Brocher, T.M. 0000-0002-9740-839X","orcid":"https://orcid.org/0000-0002-9740-839X","contributorId":69994,"corporation":false,"usgs":true,"family":"Brocher","given":"T.M.","affiliations":[],"preferred":false,"id":442525,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Hardebeck, J.","contributorId":99738,"corporation":false,"usgs":true,"family":"Hardebeck","given":"J.","email":"","affiliations":[],"preferred":false,"id":442527,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

Other than costly destructive harvest methods, no technique exists to rapidly and accurately measure above-ground perennial tissue for woody plants such as Vitis vinifera (common grape vine). Data collected from grapevine trunks and cordons were used to study the accuracy of wood volume derived from laser scanning as compared with volume derived from analog measurements. A set of 10 laser scan datasets were collected for each of 36 vines from which volume was calculated using combinations of two, three, four, six and 10 scans. Likewise, analog volume measurements were made by submerging the vine trunks and cordons in water and capturing the displaced water. A regression analysis examined the relationship between digital and non-digital techniques among the 36 vines and found that the standard error drops rapidly as additional scans are added to the volume calculation process and stabilizes at the four-view geometry with an average Pearson's product moment correlation coefficient of 0.93. Estimates of digital volumes are systematically greater than those of analog volumes and can be explained by the manner in which each technique interacts with the vine tissue. This laser scanning technique yields a highly linear relationship between vine volume and tissue mass revealing a new, rapid and non-destructive method to remotely measure standing biomass. This application shows promise for use in other ecosystems such as orchards and forests. ?? 2010 Elsevier B.V.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Computers and Electronics in Agriculture","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.compag.2010.09.005","issn":"01681699","usgsCitation":"Keightley, K., and Bawden, G., 2010, 3D volumetric modeling of grapevine biomass using Tripod LiDAR: Computers and Electronics in Agriculture, v. 74, no. 2, p. 305-312, https://doi.org/10.1016/j.compag.2010.09.005.","startPage":"305","endPage":"312","numberOfPages":"8","costCenters":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"links":[{"id":246264,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":218268,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.compag.2010.09.005"}],"volume":"74","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e25ce4b0c8380cd45af8","contributors":{"authors":[{"text":"Keightley, K.E.","contributorId":57310,"corporation":false,"usgs":true,"family":"Keightley","given":"K.E.","email":"","affiliations":[],"preferred":false,"id":456493,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bawden, G.W.","contributorId":61139,"corporation":false,"usgs":true,"family":"Bawden","given":"G.W.","email":"","affiliations":[],"preferred":false,"id":456494,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The importance of developing a rigorous sampling design tailored to specific questions has already been discussed in the ecological and sampling literature and has provided useful tools and recommendations to sample and analyse ecological data. However, sampling issues are often difficult to overcome in ecological studies due to apparent inconsistencies between theory and practice, often leading to the implementation of simplified sampling designs that suffer from unknown biases. Moreover, we believe that classical sampling principles which are based on estimation of means and variances are insufficient to fully address many ecological questions that rely on estimating relationships between a response and a set of predictor variables over time and space. Our objective is thus to highlight the importance of selecting an appropriate sampling space and an appropriate sampling design. We also emphasize the importance of using prior knowledge of the study system to estimate models or complex parameters and thus better understand ecological patterns and processes generating these patterns. Using a semi-virtual simulation study as an illustration we reveal how the selection of the space (e.g. geographic, climatic), in which the sampling is designed, influences the patterns that can be ultimately detected. We also demonstrate the inefficiency of common sampling designs to reveal response curves between ecological variables and climatic gradients. Further, we show that response-surface methodology, which has rarely been used in ecology, is much more efficient than more traditional methods. Finally, we discuss the use of prior knowledge, simulation studies and model-based designs in defining appropriate sampling designs. We conclude by a call for development of methods to unbiasedly estimate nonlinear ecologically relevant parameters, in order to make inferences while fulfilling requirements of both sampling theory and field work logistics. ?? 2010 The Authors.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecography","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1600-0587.2010.06421.x","issn":"09067590","usgsCitation":"Albert, C., Yoccoz, N.G., Edwards, T., Graham, C., Zimmermann, N., and Thuiller, W., 2010, Sampling in ecology and evolution - bridging the gap between theory and practice: Ecography, v. 33, no. 6, p. 1028-1037, https://doi.org/10.1111/j.1600-0587.2010.06421.x.","startPage":"1028","endPage":"1037","numberOfPages":"10","costCenters":[],"links":[{"id":218236,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1600-0587.2010.06421.x"},{"id":246228,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"33","issue":"6","noUsgsAuthors":false,"publicationDate":"2010-12-09","publicationStatus":"PW","scienceBaseUri":"505ab084e4b0c8380cd87b4c","contributors":{"authors":[{"text":"Albert, C.H.","contributorId":50765,"corporation":false,"usgs":true,"family":"Albert","given":"C.H.","email":"","affiliations":[],"preferred":false,"id":456478,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Yoccoz, Nigel G.","contributorId":61537,"corporation":false,"usgs":true,"family":"Yoccoz","given":"Nigel","email":"","middleInitial":"G.","affiliations":[{"id":33046,"text":"Norwegian Institute for Nature Research","active":true,"usgs":false}],"preferred":false,"id":456479,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Edwards, T.C.","contributorId":72163,"corporation":false,"usgs":true,"family":"Edwards","given":"T.C.","email":"","affiliations":[],"preferred":false,"id":456480,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Graham, C.H.","contributorId":86611,"corporation":false,"usgs":true,"family":"Graham","given":"C.H.","email":"","affiliations":[],"preferred":false,"id":456482,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Zimmermann, N.E.","contributorId":24547,"corporation":false,"usgs":true,"family":"Zimmermann","given":"N.E.","email":"","affiliations":[],"preferred":false,"id":456477,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Thuiller, W.","contributorId":73034,"corporation":false,"usgs":true,"family":"Thuiller","given":"W.","affiliations":[],"preferred":false,"id":456481,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

The understanding of these near-surface processes is relevant to issues of runoff generation, groundwater-surface water interactions, catchment export of nutrients, dissolved organic carbon, contaminants (e.g. mercury) and ultimately surface water health. We develop a 3-D physics-based representation of the Panola Mountain Research Watershed experimental hillslope using the TOUGH2 sub-surface flow and transport simulator. A recent investigation of sub-surface flow within this experimental hillslope has generated important knowledge of threshold rainfall-runoff response and its relation to patterns of transient water table development. This work has identified components of the 3-D sub-surface, such as bedrock topography, that contribute to changing connectivity in saturated zones and the generation of sub-surface stormflow. Here, we test the ability of a 3-D hillslope model (both calibrated and uncalibrated) to simulate forested hillslope rainfall-runoff response and internal transient sub-surface stormflow dynamics. We also provide a transparent illustration of physics-based model development, issues of parameterization, examples of model rejection and usefulness of data types (e.g. runoff, mean soil moisture and transient water table depth) to the model enterprise. Our simulations show the inability of an uncalibrated model based on laboratory and field characterization of soil properties and topography to successfully simulate the integrated hydrological response or the distributed water table within the soil profile. Although not an uncommon result, the failure of the field-based characterized model to represent system behaviour is an important challenge that continues to vex scientists at many scales. We focus our attention particularly on examining the influence of bedrock permeability, soil anisotropy and drainable porosity on the development of patterns of transient groundwater and sub-surface flow. Internal dynamics of transient water table development prove to be essential in determining appropriate model parameterization. ?? 2010 John Wiley & Sons, Ltd.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Hydrological Processes","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1002/hyp.7819","issn":"08856087","usgsCitation":"James, A., McDonnell, J.J., Tromp-Van Meerveld, I., and Peters, N., 2010, Gypsies in the palace: Experimentalist's view on the use of 3-D physics-based simulation of hillslope hydrological response: Hydrological Processes, v. 24, no. 26, p. 3878-3893, https://doi.org/10.1002/hyp.7819.","startPage":"3878","endPage":"3893","numberOfPages":"16","costCenters":[],"links":[{"id":241262,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":213617,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/hyp.7819"}],"volume":"24","issue":"26","noUsgsAuthors":false,"publicationDate":"2010-12-10","publicationStatus":"PW","scienceBaseUri":"505a2e6be4b0c8380cd5c50d","contributors":{"authors":[{"text":"James, A.L.","contributorId":40710,"corporation":false,"usgs":true,"family":"James","given":"A.L.","email":"","affiliations":[],"preferred":false,"id":437584,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"McDonnell, Jeffery J. 0000-0002-3880-3162","orcid":"https://orcid.org/0000-0002-3880-3162","contributorId":62723,"corporation":false,"usgs":false,"family":"McDonnell","given":"Jeffery","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":437585,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Tromp-Van Meerveld, I.","contributorId":103882,"corporation":false,"usgs":true,"family":"Tromp-Van Meerveld","given":"I.","email":"","affiliations":[],"preferred":false,"id":437586,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Peters, N.E.","contributorId":33332,"corporation":false,"usgs":true,"family":"Peters","given":"N.E.","email":"","affiliations":[],"preferred":false,"id":437583,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

The goal of this field-monitoring project was to assess how and under what circumstances nitrogen (N) nutrients under cultivated corn that is irrigated with this treated wastewater can reach the deep ground water of the underlying High Plains aquifer, and what can realistically be done to minimize this problem. We collected 15.2-m-deep cores for physical and chemical properties characterization; installed neutron moisture-probe access tubes and suction lysimeters for periodic measurements; sampled area monitoring, irrigation, and domestic wells; performed dye-tracer experiments to examine soil preferential-flow processes through macropores; and obtained climatic, crop, irrigation, and N-application rate records. These data and additional information were used in the comprehensive Root Zone Water Quality Model (RZWQM2) to identify key parameters and processes that influence N losses in the study area. We demonstrated that nitrate-N transport processes result in significant accumulations of N in the thick vadose zone. We also showed that nitrate-N in the underlying ground water is increasing with time and that the source of the nitrate is from the wastewater applications. RZWQM2 simulations indicated that macropore flow is generated particularly during heavy rainfall events, but during our 2005-06 simulations the total macropore flow was only about 3% of precipitation for one of two investigated sites, whereas it was more than 13% for the other site. Our calibrated model for the two wastewater-irrigated study sites indicated that reducing current levels of corn N fertilization by half or more to the level of 170 kg/ha substantially increases N-use efficiency and achieves near-maximum crop yield. Combining such measures with a crop rotation that includes alfalfa should further reduce the amounts of residual N in the soil, as indicated in one of the study sites that had alfalfa in past crop rotations.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Current Research in Earth Sciences","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","usgsCitation":"Sophocleous, M., Townsend, M., Vocasek, F., Ma, L., and Ashok, K., 2010, Treated wastewater and Nitrate transport beneath irrigated fields near Dodge city, Kansas: Current Research in Earth Sciences, v. 258, no. 1, p. 1-31.","startPage":"1","endPage":"31","numberOfPages":"31","costCenters":[],"links":[{"id":241565,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"258","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bb78fe4b08c986b32734e","contributors":{"authors":[{"text":"Sophocleous, M.","contributorId":13373,"corporation":false,"usgs":true,"family":"Sophocleous","given":"M.","email":"","affiliations":[],"preferred":false,"id":437507,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Townsend, M.A.","contributorId":88785,"corporation":false,"usgs":true,"family":"Townsend","given":"M.A.","email":"","affiliations":[],"preferred":false,"id":437511,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Vocasek, F.","contributorId":51996,"corporation":false,"usgs":true,"family":"Vocasek","given":"F.","email":"","affiliations":[],"preferred":false,"id":437509,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Ma, Liwang","contributorId":29140,"corporation":false,"usgs":true,"family":"Ma","given":"Liwang","email":"","affiliations":[],"preferred":false,"id":437508,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Ashok, K.C.","contributorId":56867,"corporation":false,"usgs":true,"family":"Ashok","given":"K.C.","email":"","affiliations":[],"preferred":false,"id":437510,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

These shells are composed largely of aragonite (CaCO3) and potentially could be used for radiocarbon dating, but they must meet two criteria before their 14C ages can be considered to be reliable: (1) when gastropods are alive, the 14C activity of their shells must be in equilibrium with the 14C activity of the atmosphere, and (2) after burial, their shells must behave as closed systems with respect to carbon. To evaluate the first criterion, we conducted a comprehensive examination of the 14C content of the most common small terrestrial gastropods in North America, including 247 AMS measurements of modern shell material (3749 individual shells) from 46 different species. The modern gastropods that we analyzed were all collected from habitats on carbonate terrain and, therefore, the data presented here represent worst-case scenarios. In sum, ~78% of the shell aliquots that we analyzed did not contain dead carbon from limestone or other carbonate rocks even though it was readily available at all sites, 12% of the aliquots contained between 5 and 10% dead carbon, and a few (3% of the total) contained more than 10%. These results are significantly lower than the 20-30% dead carbon that has been reported previously for larger taxa living in carbonate terrain. For the second criterion, we report a case study from the American Midwest in which we analyzed fossil shells of small terrestrial gastropods (7 taxa; 18 AMS measurements; 173 individual shells) recovered from late-Pleistocene sediments. The fossil shells yielded 14C ages that were statistically indistinguishable from 14C ages of well-preserved plant macrofossils from the same stratum. Although just one site, these results suggest that small terrestrial gastropod shells may behave as closed systems with respect to carbon over geologic timescales. More work on this subject is needed, but if our case study site is representative of other sites, then fossil shells of some small terrestrial gastropods, including at least five common genera, Catinella, Columella, Discus, Gastrocopta, and Succinea, should yield reliable 14C ages, regardless of the local geologic substrate. ?? 2010.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Quaternary Geochronology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.quageo.2010.01.001","issn":"18711014","usgsCitation":"Pigati, J., Rech, J., and Nekola, J., 2010, Radiocarbon dating of small terrestrial gastropod shells in North America: Quaternary Geochronology, v. 5, no. 5, p. 519-532, https://doi.org/10.1016/j.quageo.2010.01.001.","startPage":"519","endPage":"532","numberOfPages":"14","costCenters":[],"links":[{"id":246289,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":218290,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.quageo.2010.01.001"}],"volume":"5","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a93e1e4b0c8380cd810a7","contributors":{"authors":[{"text":"Pigati, J.S.","contributorId":80486,"corporation":false,"usgs":true,"family":"Pigati","given":"J.S.","email":"","affiliations":[],"preferred":false,"id":456354,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Rech, J.A.","contributorId":79659,"corporation":false,"usgs":true,"family":"Rech","given":"J.A.","affiliations":[],"preferred":false,"id":456353,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Nekola, J.C.","contributorId":83776,"corporation":false,"usgs":true,"family":"Nekola","given":"J.C.","affiliations":[],"preferred":false,"id":456355,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Extraction of coalbed natural gas (CBNG) often results in disposal of large quantities of CBNG product water, which may affect aquatic ecosystems. We evaluated the effects of CBNG development on fish assemblages in tributary streams of the Powder and Tongue rivers. We used treatment and control, impact versus reference sites comparisons, surveys of CBNG product-water streams and in situ fish survival approaches to determine if CBNG development affected fish assemblages.2. Several of our results suggested that CBNG development did not affect fish assemblages. Species richness and index of biotic integrity (IBI) scores were similar in streams with and streams without CBNG development, and overall biotic integrity was not related to the number or density of CBNG wells. Fish occurred in one stream that was composed largely or entirely of CBNG product water. Sentinel fish survived in cages at treatment sites where no or few fish were captured, suggesting that factors such as lack of stream connectivity rather than water quality limited fish abundance at these sites. Fish species richness did not differ significantly from 1994 to 2006 in comparisons of CBNG-developed and undeveloped streams. Biotic integrity declined from 1994 to 2006; however, declines occurred at both impact and reference sites, possibly because of long-term drought.3. Some evidence suggested that CBNG development negatively affected fish assemblages, or may do so over time. Specific conductivity was on average higher in treatment streams and was negatively related to biotic integrity. Four IBI species richness metrics were negatively correlated with the number or density of CBNG wells in the catchment above sampling sites. Bicarbonate, one of the primary ions in product water, was significantly higher in developed streams and may have limited abundance of longnose dace (Rhinichthys cataractae). Total dissolved solids, alkalinity, magnesium and sulphate were significantly higher in developed streams.4. Biological monitoring conducted before the development of CBNG, and continuing through the life of development and reclamation, together with data on the quantity, quality and fate of CBNG product water will allow robust assessment of potential effects of future CBNG development worldwide. ?? 2010 Blackwell Publishing Ltd.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Freshwater Biology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1365-2427.2010.02480.x","issn":"00465070","usgsCitation":"Davis, W., Bramblett, R., and Zale, A., 2010, Effects of coalbed natural gas development on fish assemblages in tributary streams of the Powder and Tongue rivers: Freshwater Biology, v. 55, no. 12, p. 2612-2625, https://doi.org/10.1111/j.1365-2427.2010.02480.x.","startPage":"2612","endPage":"2625","numberOfPages":"14","costCenters":[],"links":[{"id":218264,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1365-2427.2010.02480.x"},{"id":246260,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"55","issue":"12","noUsgsAuthors":false,"publicationDate":"2010-08-24","publicationStatus":"PW","scienceBaseUri":"505a06b6e4b0c8380cd513ab","contributors":{"authors":[{"text":"Davis, W.N.","contributorId":107543,"corporation":false,"usgs":true,"family":"Davis","given":"W.N.","email":"","affiliations":[],"preferred":false,"id":456344,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bramblett, R.G.","contributorId":76576,"corporation":false,"usgs":true,"family":"Bramblett","given":"R.G.","email":"","affiliations":[],"preferred":false,"id":456343,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Zale, A.V.","contributorId":15793,"corporation":false,"usgs":true,"family":"Zale","given":"A.V.","affiliations":[],"preferred":false,"id":456342,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Spatially-limited diffuse tectonic deformation within the Northeast Caribbean Plate Boundary Zone likely led to the development of the submerged Mona Passage between Puerto Rico and the Dominican Republic. GPS geodetic data and a moderate to high level of seismicity indicate that extension within the region is ongoing. Newly-collected high-resolution multibeam bathymetry and multi-channel seismic reflection profiles and previously-collected samples are used here to determine the tectonic evolution of the Mona Passage intra-arc region. The passage is floored almost completely by Oligocene-Pliocene carbonate platform strata, which have undergone submarine and subaerial erosion. Structurally, the passage is characterized by W- to NNW-trending normal faults that offset the entire thickness of the Oligo-Pliocene carbonate platform rocks. The orientation of these faults is compatible with the NE-oriented extension vector observed in GPS data. Fault geometry best fits an oblique extension model rather than previously proposed single-phase, poly-phase, bending-moment, or rotation extension models. The intersection of these generally NW-trending faults in Mona Passage with the N-S oriented faults of Mona Canyon may reflect differing responses of the brittle upper-crust, along an arc-forearc rheological boundary, to oblique subduction along the Puerto Rico trench. Several faults within the passage, if ruptured completely, are long enough to generate earthquakes with magnitudes on the order of Mw 6.5-7. ?? 2010.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Tectonophysics","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.tecto.2010.07.002","issn":"00401951","usgsCitation":"Chaytor, J., and ten Brink, U., 2010, Extension in Mona Passage, Northeast Caribbean: Tectonophysics, v. 493, no. 1-2, p. 74-92, https://doi.org/10.1016/j.tecto.2010.07.002.","startPage":"74","endPage":"92","numberOfPages":"19","ipdsId":"IP-017925","costCenters":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":246380,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":218378,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.tecto.2010.07.002"}],"volume":"493","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0e42e4b0c8380cd53387","contributors":{"authors":[{"text":"Chaytor, J.D.","contributorId":80936,"corporation":false,"usgs":true,"family":"Chaytor","given":"J.D.","affiliations":[],"preferred":false,"id":456232,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"ten Brink, Uri S. 0000-0001-6858-3001 utenbrink@usgs.gov","orcid":"https://orcid.org/0000-0001-6858-3001","contributorId":127560,"corporation":false,"usgs":true,"family":"ten Brink","given":"Uri S.","email":"utenbrink@usgs.gov","affiliations":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true},{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true}],"preferred":false,"id":456233,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

However, the GOM region has the highest rate of wetland loss in the USA. Protection and management of these vital GOM habitats are critical to sustainable shrimp fisheries. Brown shrimp (Farfantepenaeus aztecus) are a major component of GOM fisheries. We present an approach for estimating the areal extent of suitable habitat for post-larval and juvenile brown shrimp in Mobile Bay, Alabama, using an existing habitat suitability index model for the northern GOM calculated from probabilistic survey of water quality and sediment data, land cover data, and submerged aquatic vegetation coverages. This estuarine scale approach is intended to support targeted protection and restoration of these habitats. These analyses indicate that approximately 60% of the area of Mobile Bay is categorized as suitable to near optimal for post-larval and juvenile shrimp and 38% of the area is marginally to minimally suitable. We identify potential units within Mobile Bay for targeted restoration to improve habitat suitability. ?? 2010 Springer Science+Business Media B.V.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Monitoring and Assessment","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1007/s10661-009-1303-0","issn":"01676369","usgsCitation":"Smith, L., Nestlerode, J., Harwell, L., and Bourgeois, P., 2010, The areal extent of brown shrimp habitat suitability in Mobile Bay, Alabama, USA: Targeting vegetated habitat restoration: Environmental Monitoring and Assessment, v. 171, no. 1-4, p. 611-620, https://doi.org/10.1007/s10661-009-1303-0.","startPage":"611","endPage":"620","numberOfPages":"10","costCenters":[],"links":[{"id":218352,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10661-009-1303-0"},{"id":246352,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"171","issue":"1-4","noUsgsAuthors":false,"publicationDate":"2010-01-16","publicationStatus":"PW","scienceBaseUri":"505ba9d1e4b08c986b322525","contributors":{"authors":[{"text":"Smith, L.M.","contributorId":82650,"corporation":false,"usgs":true,"family":"Smith","given":"L.M.","email":"","affiliations":[],"preferred":false,"id":456230,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Nestlerode, J.A.","contributorId":67738,"corporation":false,"usgs":true,"family":"Nestlerode","given":"J.A.","affiliations":[],"preferred":false,"id":456229,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Harwell, L.C.","contributorId":45162,"corporation":false,"usgs":true,"family":"Harwell","given":"L.C.","email":"","affiliations":[],"preferred":false,"id":456228,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Bourgeois, P.","contributorId":94498,"corporation":false,"usgs":true,"family":"Bourgeois","given":"P.","affiliations":[],"preferred":false,"id":456231,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

We use synthetic examples based on two recent field experiments to demonstrate that a high degree of nonuniqueness remains in estimates of hydraulic parameter fields even when those estimates are based on simultaneous analysis of a number of carefully controlled hydraulic tests. We must, therefore, be careful not to oversell the technique to the community of practicing hydrogeologists, promising a degree of accuracy and resolution that, in many settings, will remain unattainable, regardless of the amount of effort invested in the field investigation. No practically feasible amount of hydraulic tomography data will ever remove the need to regularize or bias the inverse problem in some fashion in order to obtain a unique solution. Thus, along with improving the resolution of hydraulic tomography techniques, we must also strive to couple those techniques with procedures for experimental design and uncertainty assessment and with other more cost-effective field methods, such as geophysical surveying and, in unconsolidated formations, direct-push profiling, in order to develop methods for subsurface characterization with the resolution and accuracy needed for practical field applications.

The study uses data from the Hydrometeorology Testbed (HMT), which conducted its first field study in California during the 2005/06 cool season. National Weather Service River Forecast Center (NWS RFC) gridded QPFs for 24-h periods at 24-h (day 1), 48-h (day 2), and 72-h (day 3) forecast lead times plus 24-h quantitative precipitation estimates (QPEs) fromsites in California (CA) and Oregon-Washington (OR-WA) are used. During the 172-day period studied, some sites received more than 254 cm (100 in.) of precipitation. The winter season produced many extreme precipitation events, including 90 instances when a site received more than 7.6 cm (3.0 in.) of precipitation in 24 h (i.e., an \"event\") and 17 events that exceeded 12.7 cm (24 h)-1 [5.0 in. (24 h)-1]. For the 90 extreme events f.7.6 cm (24 h)-1 [3.0 in. (24 h)-1]g, almost 90% of all the 270 QPFs (days 1-3) were biased low, increasingly so with greater lead time. Of the 17 observed events exceeding 12.7 cm (24 h)-1 [5.0 in. (24 h)-1], only 1 of those events was predicted to be that extreme. Almost all of the extreme events correlated with the presence of atmospheric river conditions. Total seasonal QPF biases for all events fi.e., $0.025 cm (24 h)-1 [0.01 in. (24 h)-1]g were sensitive to local geography and were generally biased low in the California-Nevada River Forecast Center (CNRFC) region and high in the Northwest River Forecast Center(NWRFC) domain. The low bias in CA QPFs improved with shorter forecast lead time and worsened for extreme events. Differences were also noted between the CNRFC and NWRFC in terms of QPF and the frequency of extreme events. A key finding from this study is that there were more precipitation events .7.6 cm (24 h)-1 [3.0 in. (24 h)21] in CA than in OR-WA. Examination of 422 Cooperative Observer Program (COOP) sites in the NWRFC domain and 400 in the CNRFC domain found that the thresholds for the top 1% and top 0.1%of precipitation events were 7.6 cm (24 h)21 [3.0 in. (24 h)-1] and 14.2 cm (24 h)-1 [5.6 in. (24 h)-1] or greater for the CNRFC and only 5.1 cm (24 h)-1 [2.0 in. (24 h)-1] and 9.4 cm (24 h)-1 [3.7 in. (24 h)-1] for the NWRFC, respectively. Similar analyses for all NWS RFCs showed that the threshold for the top 1% of events varies from;3.8 cm (24 h)-1 [1.5 in. (24 h)-1] in the Colorado Basin River Forecast Center (CBRFC) to~5.1 cm (24 h)-1 [3.0 in. (24 h)-1] in the northern tier of RFCs and;7.6 cm (24 h)-1 [3.0 in. (24 h)-1] in both the southern tier and the CNRFC. It is recommended that NWS QPF performance in the future be assessed for extreme events using these thresholds. ?? 2010 American Meteorological Society.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Hydrometeorology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1175/2010JHM1232.1","issn":"1525755X","usgsCitation":"Ralph, F., Sukovich, E., Reynolds, D., Dettinger, M., Weagle, S., Clark, W., and Neiman, P., 2010, Assessment of extreme quantitative precipitation forecasts and development of regional extreme event thresholds using data from HMT-2006 and COOP observers: Journal of Hydrometeorology, v. 11, no. 6, p. 1286-1304, https://doi.org/10.1175/2010JHM1232.1.","startPage":"1286","endPage":"1304","numberOfPages":"19","costCenters":[],"links":[{"id":475889,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1175/2010jhm1232.1","text":"Publisher Index Page"},{"id":218377,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1175/2010JHM1232.1"},{"id":246379,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"11","issue":"6","noUsgsAuthors":false,"publicationDate":"2010-12-01","publicationStatus":"PW","scienceBaseUri":"5059ee2fe4b0c8380cd49bf1","contributors":{"authors":[{"text":"Ralph, F.M.","contributorId":39174,"corporation":false,"usgs":true,"family":"Ralph","given":"F.M.","email":"","affiliations":[],"preferred":false,"id":456078,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sukovich, E.","contributorId":25395,"corporation":false,"usgs":true,"family":"Sukovich","given":"E.","email":"","affiliations":[],"preferred":false,"id":456077,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Reynolds, D.","contributorId":76149,"corporation":false,"usgs":true,"family":"Reynolds","given":"D.","affiliations":[],"preferred":false,"id":456080,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Dettinger, M. 0000-0002-7509-7332","orcid":"https://orcid.org/0000-0002-7509-7332","contributorId":78909,"corporation":false,"usgs":true,"family":"Dettinger","given":"M.","affiliations":[],"preferred":false,"id":456081,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Weagle, S.","contributorId":74616,"corporation":false,"usgs":true,"family":"Weagle","given":"S.","email":"","affiliations":[],"preferred":false,"id":456079,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Clark, W.","contributorId":102315,"corporation":false,"usgs":true,"family":"Clark","given":"W.","affiliations":[],"preferred":false,"id":456082,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Neiman, P.J.","contributorId":14991,"corporation":false,"usgs":true,"family":"Neiman","given":"P.J.","email":"","affiliations":[],"preferred":false,"id":456076,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

Although a significant effort has been put forth by volunteers, questions remain as to whether volunteer data are accurate and can be used by regulators. In this study, typical volunteer water quality measurements from laboratory and environmental samples in Iowa were analyzed for error and bias. Volunteer measurements of nitrate+nitrite were significantly lower (about 2-fold) than concentrations determined via standard methods in both laboratory-prepared and environmental samples. Total reactive phosphorus concentrations analyzed by volunteers were similar to measurements determined via standard methods in laboratory-prepared samples and environmental samples, but were statistically lower than the actual concentration in four of the five laboratory-prepared samples. Volunteer water quality measurements were successful in identifying and classifying most of the waters which violate United States Environmental Protection Agency recommended water quality criteria for total nitrogen (66%) and for total phosphorus (52%) with the accuracy improving when accounting for error and biases in the volunteer data. An understanding of the error and bias in volunteer water quality measurements can allow regulators to incorporate volunteer water quality data into total maximum daily load planning or state water quality reporting. ?? 2010 American Chemical Society.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Science and Technology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1021/es100164c","issn":"0013936X","usgsCitation":"Loperfido, J., Beyer, P., Just, C., and Schnoor, J., 2010, Uses and biases of volunteer water quality data: Environmental Science & Technology, v. 44, no. 19, p. 7193-7199, https://doi.org/10.1021/es100164c.","startPage":"7193","endPage":"7199","numberOfPages":"7","costCenters":[],"links":[{"id":218349,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1021/es100164c"},{"id":246349,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"44","issue":"19","noUsgsAuthors":false,"publicationDate":"2010-06-11","publicationStatus":"PW","scienceBaseUri":"505bc003e4b08c986b329e9a","contributors":{"authors":[{"text":"Loperfido, J.V.","contributorId":90970,"corporation":false,"usgs":true,"family":"Loperfido","given":"J.V.","email":"","affiliations":[],"preferred":false,"id":456055,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Beyer, P.","contributorId":71815,"corporation":false,"usgs":true,"family":"Beyer","given":"P.","email":"","affiliations":[],"preferred":false,"id":456054,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Just, C.L.","contributorId":94899,"corporation":false,"usgs":true,"family":"Just","given":"C.L.","email":"","affiliations":[],"preferred":false,"id":456057,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Schnoor, J.

A 3-a study of inorganic Hg (IHg) and methylmercury (MeHg) was conducted in physical media (soil, sediment, surface water, porewater and soil/sediment extracts) to identify non-point sources, transport mechanisms, and potential controls on Hg(II)-methylation. Data collected from surface water and sediment indicate that the majority of the non-point sources of IHg to the South River are within the first 14. km downstream from the historic point source. Partitioning data indicate that particle bound IHg is introduced in this reach, releasing dissolved and colloidal bound IHg, which is transported downstream. Extraction experiments revealed that floodplain soils released a higher fraction of their IHg content in aqueous extractions than fine-grained sediment (FGS). Based on ultrafiltration [<5000 nominal molecular weight cutoff (NMWC)] the majority of soil IHg released was colloidal in nature, providing evidence for the continued evolution of IHg for Hg(II)-methylation from soil. Strong seasonal patterns in MeHg concentrations were observed in surface water and sediment. The highest concentrations of MeHg in surface water were observed at moderate temperatures, suggesting that other factors limit net Hg(II)-methylation. Seasonal changes in sediment organic content and the fraction of 1. N KOH-extractable THg were also observed and may be important factors in controlling net Hg(II)-methylation rates. Sulfate concentrations in surface water are low and the evidence suggests that Fe reduction may be an important Hg(II)-methylation process. The highest sediment MeHg concentrations were observed in habitats with large amounts of FGS, which are more prevalent in the upper half of the study area due to the lower hydrologic gradient and agricultural impacts. Past and present land use practices and other geomorphologic controls contribute to the erosion of banks and accumulation of fine-grained sediment in this section of the river, acting as sources of IHg. ?? 2010 Elsevier Ltd.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Applied Geochemistry","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.apgeochem.2010.09.004","issn":"08832927","usgsCitation":"Flanders, J., Turner, R., Morrison, T., Jensen, R., Pizzuto, J., Skalak, K., and Stahl, R., 2010, Distribution, behavior, and transport of inorganic and methylmercury in a high gradient stream: Applied Geochemistry, v. 25, no. 11, p. 1756-1769, https://doi.org/10.1016/j.apgeochem.2010.09.004.","startPage":"1756","endPage":"1769","numberOfPages":"14","costCenters":[],"links":[{"id":218581,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.apgeochem.2010.09.004"},{"id":246606,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"25","issue":"11","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a031ce4b0c8380cd50346","contributors":{"authors":[{"text":"Flanders, J.R.","contributorId":87401,"corporation":false,"usgs":true,"family":"Flanders","given":"J.R.","email":"","affiliations":[],"preferred":false,"id":455768,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Turner, R.R.","contributorId":29983,"corporation":false,"usgs":true,"family":"Turner","given":"R.R.","email":"","affiliations":[],"preferred":false,"id":455764,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Morrison, T.","contributorId":90966,"corporation":false,"usgs":true,"family":"Morrison","given":"T.","affiliations":[],"preferred":false,"id":455769,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Jensen, R.","contributorId":58877,"corporation":false,"usgs":true,"family":"Jensen","given":"R.","affiliations":[],"preferred":false,"id":455766,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Pizzuto, J.","contributorId":32381,"corporation":false,"usgs":true,"family":"Pizzuto","given":"J.","email":"","affiliations":[],"preferred":false,"id":455765,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Skalak, K.","contributorId":22997,"corporation":false,"usgs":true,"family":"Skalak","given":"K.","affiliations":[],"preferred":false,"id":455763,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Stahl, R.","contributorId":60888,"corporation":false,"usgs":true,"family":"Stahl","given":"R.","email":"","affiliations":[],"preferred":false,"id":455767,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

Use of sediment sources from outside the area can result in sedimentary characteristics that differ from native sediments on the surface and at depth, altering conditions for both aeolian transport to dunes and interstitial fauna. Field data were gathered on an estuarine beach to determine differences in beach profile change, depth of sediment reworking, and potential for aeolian transport due to nourishment. Data were gathered over a 20-month period 6 months prior to nourishment, 3 days after nourishment, 6 months after nourishment, and 14 months after nourishment when the beach was mechanically graded to eliminate a vertical scarp in the foreshore. The nourishment consisted of 87,900m3 of sediment emplaced to create a 1.34-km-long, 30-m-wide berm 2.3m above mean tide level. Seven percent of the fill was removed from the profile within 6 months after nourishment, accompanied by 7m in horizontal retreat of the artificial berm. The fill on the backshore remained above the zone of wave influence over a winter storm season and was separated from the active foreshore by the scarp. Nourished sediments on the intertidal foreshore were significantly different from native sediments to a depth of 0.20m below the surface. A lag surface of coarse sediment formed by deflation on the backshore, resulting in a rate of aeolian transport &lt;2% of the rate on the wave-reworked foreshore.Nourishing a beach to a level higher than would be created by natural processes can create a profile that compartmentalizes and restricts transport of sediment and movement of fauna between the foreshore and backshore. Mechanical grading can eliminate the scarp, allow for faunal interaction, and reestablish wave reworking of the backshore that will facilitate aeolian transport. Using an initial design to nourish the backshore at a lower elevation and allowing a dune to provide protection against flooding during major storms could prevent a scarp from forming and eliminate the need for follow-up grading. ?? 2010 Elsevier B.V.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecological Engineering","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.ecoleng.2010.07.016","issn":"09258574","usgsCitation":"Jackson, N., Nordstrom, K., Saini, S., and Smith, D., 2010, Effects of nourishment on the form and function of an estuarine beach: Ecological Engineering, v. 36, no. 12, p. 1709-1718, https://doi.org/10.1016/j.ecoleng.2010.07.016.","startPage":"1709","endPage":"1718","numberOfPages":"10","costCenters":[],"links":[{"id":218555,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.ecoleng.2010.07.016"},{"id":246577,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"36","issue":"12","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a076ce4b0c8380cd516be","contributors":{"authors":[{"text":"Jackson, N.L.","contributorId":104189,"corporation":false,"usgs":true,"family":"Jackson","given":"N.L.","email":"","affiliations":[],"preferred":false,"id":455762,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Nordstrom, K.F.","contributorId":17733,"corporation":false,"usgs":true,"family":"Nordstrom","given":"K.F.","email":"","affiliations":[],"preferred":false,"id":455760,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Saini, S.","contributorId":7953,"corporation":false,"usgs":true,"family":"Saini","given":"S.","email":"","affiliations":[],"preferred":false,"id":455759,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Smith, D.

Here, we study one such relatively small subduction zone by analysing the historical seismicity over the entire plate boundary region south of New Zealand, using these data to determine the seismic moment deficit of the subduction zone over the past ~100 yr. Our calculations indicate unreleased moment equivalent to a magnitude Mw 8.3 earthquake, suggesting this subduction zone has the potential to host a great, tsunamigenic event. We model this tsunami hazard and find that a tsunami caused by a great earthquake on the Puysegur subduction zone would pose threats to the coasts of southern and western South Island, New Zealand, Tasmania and southeastern Australia, nearly 2000 km distant.

We used Akaike's Information Criterion to evaluate 129 linear regression models that included all combinations of one to seven ecological indices as predictors of burbot recruitment. Two models were substantially supported by the data: (i) the number of days in which water temperatures were within optimal ranges for burbot spawning and development combined with biomass of yearling and older (YAO) yellow perch Perca flavescens (Mitchill); and (ii) biomass of YAO yellow perch. Warmer winter water temperatures and increases in yellow perch biomass were associated with decreases in burbot recruitment.

The area was regarded as seismically quiet, but between April and June 2009 a swarm of more than 30,000 earthquakes struck one of the lava fields in the province, Harrat Lunayyir, northwest Saudi Arabia. Concerned that larger damaging earthquakes might occur, the Saudi Arabian government evacuated 40,000 people from the region. Here we use geologic, geodetic and seismic data to show that the earthquake swarm resulted from magmatic dyke intrusion. We document a surface fault rupture that is 8</span><span class=\"mb\"><span class=\"mb\">&thinsp;</span></span><span>km long with 91</span><span class=\"mb\"><span class=\"mb\">&thinsp;</span></span><span>cm of offset. Surface deformation is best modelled by the shallow intrusion of a north-west trending dyke that is about 10</span><span class=\"mb\"><span class=\"mb\">&thinsp;</span></span><span>km long. Seismic waves generated during the earthquakes exhibit overlapping very low- and high-frequency components. We interpret the low frequencies to represent intrusion of magma and the high frequencies to represent fracturing of the crystalline basement rocks. Rather than extension being accommodated entirely by the central Red Sea rift axis, we suggest that the broad deformation observed in Harrat Lunayyir indicates that rift margins can remain as active sites of extension throughout rifting. Our analyses allowed us to forecast the likelihood of a future eruption or large earthquake in the region and informed the decisions made by the Saudi Arabian government to return the evacuees.</span></p>","language":"English","publisher":"Nature","publisherLocation":"New York, NY","doi":"10.1038/ngeo966","issn":"17520894","usgsCitation":"Pallister, J., McCausland, W., Jonsson, S., Lu, Z., Zahran, H., El, H.S., Aburukbah, A., Stewart, I., Lundgren, P., White, R., and Moufti, M., 2010, Broad accommodation of rift-related extension recorded by dyke intrusion in Saudi Arabia: Nature Geoscience, v. 3, p. 705-712, https://doi.org/10.1038/ngeo966.","productDescription":"8 p.","startPage":"705","endPage":"712","numberOfPages":"8","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":246605,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Saudi Arabia","state":"Harrat Lunayyir","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              37.5,\n              24\n            ],\n            [\n              37.5,\n              26\n            ],\n            [\n              39,\n              26\n            ],\n            [\n              39,\n              24\n            ],\n            [\n              37.5,\n              24\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"3","noUsgsAuthors":false,"publicationDate":"2010-09-26","publicationStatus":"PW","scienceBaseUri":"5059f285e4b0c8380cd4b208","contributors":{"authors":[{"text":"Pallister, J.S.","contributorId":46534,"corporation":false,"usgs":true,"family":"Pallister","given":"J.S.","email":"","affiliations":[],"preferred":false,"id":455626,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"McCausland, W.A.","contributorId":23003,"corporation":false,"usgs":true,"family":"McCausland","given":"W.A.","email":"","affiliations":[],"preferred":false,"id":455625,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Jonsson, Sigurjon","contributorId":72123,"corporation":false,"usgs":true,"family":"Jonsson","given":"Sigurjon","email":"","affiliations":[],"preferred":false,"id":455630,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Lu, Z.","contributorId":106241,"corporation":false,"usgs":true,"family":"Lu","given":"Z.","affiliations":[],"preferred":false,"id":455632,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Zahran, H.M.","contributorId":69001,"corporation":false,"usgs":true,"family":"Zahran","given":"H.M.","email":"","affiliations":[],"preferred":false,"id":455629,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"El, Hadidy S.","contributorId":53215,"corporation":false,"usgs":true,"family":"El","given":"Hadidy","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":455627,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Aburukbah, A.","contributorId":54057,"corporation":false,"usgs":true,"family":"Aburukbah","given":"A.","affiliations":[],"preferred":false,"id":455628,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Stewart, I.C.F.","contributorId":18914,"corporation":false,"usgs":true,"family":"Stewart","given":"I.C.F.","email":"","affiliations":[],"preferred":false,"id":455623,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Lundgren, P.R.","contributorId":95315,"corporation":false,"usgs":true,"family":"Lundgren","given":"P.R.","email":"","affiliations":[],"preferred":false,"id":455631,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"White, R.A.","contributorId":21953,"corporation":false,"usgs":true,"family":"White","given":"R.A.","email":"","affiliations":[],"preferred":false,"id":455624,"contributorType":{"id":1,"text":"Authors"},"rank":10},{"text":"Moufti, M.R.H.","contributorId":12306,"corporation":false,"usgs":true,"family":"Moufti","given":"M.R.H.","affiliations":[],"preferred":false,"id":455622,"contributorType":{"id":1,"text":"Authors"},"rank":11}]}}

We collected capture-recapture data on three populations of boreal toads (Bufo boreas [Bufo = Anaxyrus]) in the Rocky Mountains (U.S.A.). Two of the populations were infected with chytridiomycosis and one was not. We examined the effect of the presence of amphibian chytrid fungus (Batrachochytrium dendrobatidis [Bd]; the agent of chytridiomycosis) on survival probability and population growth rate. Toads that were infected with Bd had lower average annual survival probability than uninfected individuals at sites where Bd was detected, which suggests chytridiomycosis may reduce survival by 31-42% in wild boreal toads. Toads that were negative for Bd at infected sites had survival probabilities comparable to toads at the uninfected site. Evidence that environmental covariates (particularly cold temperatures during the breeding season) influenced toad survival was weak. The number of individuals in diseased populations declined by 5-7%/year over the 6 years of the study, whereas the uninfected population had comparatively stable population growth. Our data suggest that the presence of Bd in these toad populations is not causing rapid population declines. Rather, chytridiomycosis appears to be functioning as a low-level, chronic disease whereby some infected individuals survive but the overall population effects are still negative. Our results show that some amphibian populations may be coexisting with Bd and highlight the importance of quantitative assessments of survival in diseased animal populations.
