In this study, four methods for estimating groundwater recharge and two methods for estimating base flow (as a proxy for recharge) are compared at two hydrologic research sites in east-central Pennsylvania, USA. Results from the multiple methods all provided reasonable estimates of groundwater recharge that differed considerably. The estimates of mean annual recharge for the period 1994-2001 ranged from 22.9 to 35.7 cm - about 45% of the mean of all estimates. For individual years, recharge estimates from the multiple methods ranged from 30 to 42% of the mean value during the dry years and 64 to 76% of the mean value during wet years. Comparison of multiple methods was found to be useful for determining the range of plausible recharge rates and highlighting the uncertainty of the estimates. ??

Application of the test requires that the sample be unbiased and the outcomes be independent and identically distributed, conditions that are violated in several degrees by spatially continuous attributes, such as topographical elevation. A generalized form of the bootstrap method is used here for the purpose of modeling the distribution of the statistic D of the Kolmogorov-Smirnov test. The innovation is in the resampling, which in the traditional formulation of bootstrap is done by drawing from the empirical sample with replacement presuming independence. The generalization consists of preparing resamplings with the same spatial correlation as the empirical sample. This is accomplished by reading the value of unconditional stochastic realizations at the sampling locations, realizations that are generated by simulated annealing. The new approach was tested by two empirical samples taken from an exhaustive sample closely following a lognormal distribution. One sample was a regular, unbiased sample while the other one was a clustered, preferential sample that had to be preprocessed. Our results show that the p-value for the spatially correlated case is always larger that the p-value of the statistic in the absence of spatial correlation, which is in agreement with the fact that the information content of an uncorrelated sample is larger than the one for a spatially correlated sample of the same size. ??

As part of the Carolinas Coastal Change Processes Project, a geologic framework study in June of 2008 by the Woods Hole Coastal and Marine Science Center's Sea Floor Mapping Group focused on the seaward limit of Diamond Shoals and provided high resolution bathymetric data, surficial sediment characteristics, and subsurface geologic stratigraphy. These data also provided unprecedented guidance to identify deployment locations for tripods and moorings to investigate the processes that control sediment transport at Diamond Shoals. Equipment was deployed at three sites from early January, 2009 through early May, 2009: north and south of the shoals at 15 m depth, and at the tip at 24 m depth. Many strong storm systems were recorded during that time period. Mounted on the tripods were instruments to measure surface waves, pressure, current velocity, bottom turbulence, suspended-sediment profiles, and sea-floor sand-ripple bedforms. Many instruments were designed and programmed to sample in high resolution in time and space, as fast as 8 Hz hourly bursts and as small as 6 cm bin sizes in near bottom profiles. A second tripod at the north site also held a visual camera system and sonar imaging system which document seafloor bedforms. The region is known for its dynamics, and one of the tripods tipped over towards the end of the experiment. A preliminary look at the data suggests the region is characterized by high energy. Raw data from a burst recorded at the south site on Mar. 26<sup>th</sup> show instantaneous flow speed at 150 cm/s at 0.5 m above the seabed. This paper reports preliminary highlights of the observations, based on raw data, and lessons learned from a deployment of large tripod systems in such a dynamic location. ??2009 MTS.","largerWorkTitle":"MTS/IEEE Biloxi - Marine Technology for Our Future: Global and Local Challenges, OCEANS 2009","conferenceTitle":"MTS/IEEE Biloxi - Marine Technology for Our Future: Global and Local Challenges, OCEANS 2009","conferenceDate":"26 October 2009 through 29 October 2009","conferenceLocation":"Biloxi, MS","language":"English","isbn":"9781424449606","usgsCitation":"Martini, M., Armstrong, B., and Warner, J., 2009, High resolution near-bed observations in winter near Cape Hatteras, North Carolina, <i>in</i> MTS/IEEE Biloxi - Marine Technology for Our Future: Global and Local Challenges, OCEANS 2009, Biloxi, MS, 26 October 2009 through 29 October 2009.","costCenters":[],"links":[{"id":243143,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a30cce4b0c8380cd5d962","contributors":{"authors":[{"text":"Martini, M.","contributorId":24909,"corporation":false,"usgs":true,"family":"Martini","given":"M.","email":"","affiliations":[],"preferred":false,"id":450567,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Armstrong, B.","contributorId":15845,"corporation":false,"usgs":true,"family":"Armstrong","given":"B.","email":"","affiliations":[],"preferred":false,"id":450566,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Warner, J.C.","contributorId":46644,"corporation":false,"usgs":true,"family":"Warner","given":"J.C.","email":"","affiliations":[],"preferred":false,"id":450568,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

These near-closest-approach observations have the highest signal-to-noise, the finest spatial resolution, and the least atmospheric influence of any near-infrared lake observation to date. We use the large, spatially flat, and low-albedo interior of Ontario Lacus as a calibration target allowing us to derive an analytical atmospheric correction for emission angle. The dark lake interior is surrounded by two separate annuli that follow the lake interior's contours. The inner annulus is uniformly dark, but not so much as the interior lake, and is generally 5-10 kilometers wide at the lake's southeastern margin. We propose that it represents wet lakebed sediments exposed by either tidal sloshing of the lake or seasonal methane loss leading to lower lake-volume. The exterior annulus is bright and shows a spectrum consistent with a relatively low water-ice content relative to the rest of Titan. It may represent fine-grained condensate deposits from a past era of higher lake level. Together, the annuli seem to indicate that the lake level for Ontario Lacus has changed over time. This hypothesis can be tested with observations scheduled for future Titan flybys. ?? 2008 Elsevier Inc.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Icarus","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.icarus.2008.12.028","issn":"00191035","usgsCitation":"Barnes, J.W., Brown, R.H., Soderblom, J., Soderblom, L., Jaumann, R., Jackson, B., Le Mouelic, S., Sotin, C., Buratti, B.J., Pitman, K., Baines, K.H., Clark, R.N., Nicholson, P.D., Turtle, E.P., and Perry, J., 2009, Shoreline features of Titan's Ontario Lacus from Cassini/VIMS observations: Icarus, v. 201, no. 1, p. 217-225, https://doi.org/10.1016/j.icarus.2008.12.028.","startPage":"217","endPage":"225","numberOfPages":"9","costCenters":[],"links":[{"id":215762,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.icarus.2008.12.028"},{"id":243585,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"201","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b8e94e4b08c986b318a09","contributors":{"authors":[{"text":"Barnes, J.

Recent evidence of larval lake whitefish production in a historic spawning area (Chaumont Bay) might signal a recovery of this species in New York waters. We surveyed coastal and open water areas to evaluate densities and estimate total abundance of larval lake whitefish in Chaumont Bay. Other historic spawning areas and embayments with appropriate spawning and nursery habitat were also surveyed, but only a few larvae were found outside of Chaumont Bay. Lake whitefish larvae were found in every embayment sampled within Chaumont Bay, with larval densities of nearly 600/1000 m<sup>2</sup> in some samples. Greatest abundances occurred in the northern sectors and near the mouth of the bay. Open water densities were generally less than half that of nearshore sites. The total bay-wide estimate for 2005 was approximately 644,000 lake whitefish larvae, but dropped to 230,000–400,000 in 2006 and 2007, respectively. Mean larval growth rates (0.36 mm/day) did not differ by year, but were consistently higher in early May than in late April. Lake whitefish production in Chaumont Bay is encouraging for this species, but the cause and persistence of the decline after 2005 can be determined only by continued monitoring. Other possible bottlenecks of survival may exist at juvenile and adult stages and could significantly affect recruitment dynamics. This species is sensitive to normal climatic fluctuations and increased variability associated with global climatic change could make winter nursery conditions unfavorable for this species.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Great Lakes Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/j.jglr.2008.10.004","issn":"03801330","usgsCitation":"McKenna, J., and Johnson, J.H., 2009, Spatial and temporal variation in distribution of larval lake whitefish in eastern Lake Ontario: signs of recovery?: Journal of Great Lakes Research, v. 35, no. 1, p. 94-100, https://doi.org/10.1016/j.jglr.2008.10.004.","productDescription":"7 p.","startPage":"94","endPage":"100","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":216489,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.jglr.2008.10.004"},{"id":244362,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"otherGeospatial":"Lake Ontario","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -79.9363,43.1696 ], [ -79.9363,44.3608 ], [ -76.0002,44.3608 ], [ -76.0002,43.1696 ], [ -79.9363,43.1696 ] ] ] } } ] }","volume":"35","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b9456e4b08c986b31a9fe","contributors":{"authors":[{"text":"McKenna, J.E.

Ammonium has been detected at concentrations that are problematic to water treatment facilities (greater than 2.0 mg/L) in this region. Paleosols characterized for this study were of Quaternary age, specifically Robein Silt samples. Paleosol samples displayed significant capacity to both store and release ammonium through experiments measuring processes of sorption, ion exchange, and weathering. Bacteria and fungi within paleosols may significantly facilitate the leaching of ammonium into groundwater by the processes of assimilation and mineralization. Bacterial genetic material (DNA) was successfully extracted from the Robein Silt, purified, and amplified by polymerase chain reaction to produce 16S rRNA terminal restriction fragment length polymorphism (TRFLP) community analyses. The Robein Silt was found to have established diverse and viable bacterial communities. 16S rRNA TRFLP comparisons to well-known bacterial species yielded possible matches with facultative chemolithotrophs, cellulose consumers, nitrate reducers, and actinomycetes. It was concluded that the Robein Silt is both a source and reservoir for groundwater ammonium. Therefore, the occurrence of relatively large concentrations of ammonium in groundwater monitoring data may not necessarily be an indication of only anthropogenic contamination. The results of this study, however, need to be placed in a hydrological context to better understand whether paleosols can be a significant source of ammonium to drinking water supplies. ?? 2009 National Ground Water Association.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ground Water Monitoring and Remediation","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1745-6592.2009.01257.x","issn":"10693629","usgsCitation":"Glessner, J.J., and Roy, W.R., 2009, Paleosols in central Illinois as potential sources of ammonium in groundwater: Ground Water Monitoring and Remediation, v. 29, no. 4, p. 56-64, https://doi.org/10.1111/j.1745-6592.2009.01257.x.","startPage":"56","endPage":"64","numberOfPages":"9","costCenters":[],"links":[{"id":216567,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1745-6592.2009.01257.x"},{"id":244445,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"29","issue":"4","noUsgsAuthors":false,"publicationDate":"2009-11-03","publicationStatus":"PW","scienceBaseUri":"505a7455e4b0c8380cd775b6","contributors":{"authors":[{"text":"Glessner, Justin J.

Sea-level rise, one indirect consequence of increasing atmospheric CO<sub>2</sub>, poses a major challenge to long-term stability of coastal wetlands. An important question is whether direct effects of elevated CO <sub>2</sub> on the capacity of marsh plants to accrete organic material and to maintain surface elevations outweigh indirect negative effects of stressors associated with sea-level rise (salinity and flooding). 2. In this study, we used a mesocosm approach to examine potential direct and indirect effects of atmospheric CO<sub>2</sub> concentration, salinity and flooding on elevation change in a brackish marsh community dominated by a C<sub>3</sub> species, Schoenoplectus americanus, and a C<sub>4</sub> grass, Spartina patens. This experimental design permitted identification of mechanisms and their role in controlling elevation change, and the development of models that can be tested in the field. 3. To test hypotheses related to CO<sub>2</sub> and sea-level rise, we used conventional anova procedures in conjunction with structural equation modelling (SEM). SEM explained 78% of the variability in elevation change and showed the direct, positive effect of S. americanus production on elevation. The SEM indicated that C<sub>3</sub> plant response was influenced by interactive effects between CO<sub>2</sub> and salinity on plant growth, not a direct CO<sub>2</sub> fertilization effect. Elevated CO<sub>2</sub> ameliorated negative effects of salinity on S. americanus and enhanced biomass contribution to elevation. 4. The positive relationship between S. americanus production and elevation change can be explained by shoot-base expansion under elevated CO <sub>2</sub> conditions, which led to vertical soil displacement. While the response of this species may differ under other environmental conditions, shoot-base expansion and the general contribution of C<sub>3</sub> plant production to elevation change may be an important mechanism contributing to soil expansion and elevation gain in other coastal wetlands. 5. Synthesis. Our results revealed previously unrecognized interactions and mechanisms contributing to marsh elevation change, including amelioration of salt stress by elevated CO<sub>2</sub> and the importance of plant production and shoot-base expansion for elevation gain. Identification of biological processes contributing to elevation change is an important first step in developing comprehensive models that permit more accurate predictions of whether coastal marshes will persist with continued sea-level rise or become submerged. ?? 2008 The Authors.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Ecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1365-2745.2008.01449.x","issn":"00220477","usgsCitation":"Cherry, J.A., McKee, K., and Grace, J., 2009, Elevated CO<sub>2</sub> enhances biological contributions to elevation change in coastal wetlands by offsetting stressors associated with sea-level rise: Journal of Ecology, v. 97, no. 1, p. 67-77, https://doi.org/10.1111/j.1365-2745.2008.01449.x.","startPage":"67","endPage":"77","numberOfPages":"11","costCenters":[],"links":[{"id":476522,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1111/j.1365-2745.2008.01449.x","text":"Publisher Index Page"},{"id":216047,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1365-2745.2008.01449.x"},{"id":243888,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"97","issue":"1","noUsgsAuthors":false,"publicationDate":"2008-12-11","publicationStatus":"PW","scienceBaseUri":"505a08c5e4b0c8380cd51c7a","contributors":{"authors":[{"text":"Cherry, J.

The biogeochemistry at the wetland-alluvial aquifer interface differed greatly between dry and wet conditions. During dry conditions (low water table), vertically upward discharge was focused at the center of the slough from the fringe of a landfill-derived ammonium plume in the underlying aquifer, resulting in transport of relatively low concentrations of ammonium to the slough sediments with dilution and dispersion as the primary attenuation mechanism. In contrast, during wet conditions (high water table), leachate-contaminated groundwater discharged upward near the upgradient slough bank, where ammonium concentrations in the aquifer where high. Relatively high concentrations of ammonium and other leachate constituents also were transported laterally through the slough porewater to the downgradient bank in wet conditions. Concentrations of the leachate-associated constituents chloride, ammonium, non-volatile dissolved organic carbon, alkalinity, and ferrous iron more than doubled in the slough porewater on the upgradient bank during wet conditions. Chloride, non-volatile dissolved organic carbon (DOC), and bicarbonate acted conservatively during lateral transport in the aquifer and slough porewater, whereas ammonium and potassium were strongly attenuated. Nitrogen isotope variations in ammonium and the distribution of ammonium compared to other cations indicated that sorption was the primary attenuation mechanism for ammonium during lateral transport in the aquifer and the slough porewater. Ammonium attenuation was less efficient, however, in the slough porewater than in the aquifer and possibly occurred by a different sorption mechanism. A stoichiometrically balanced increase in magnesium concentration with decreasing ammonium and potassium concentrations indicated that cation exchange was the sorption mechanism in the slough porewater. Only a partial mass balance could be determined for cations exchanged for ammonium and potassium in the aquifer, indicating that some irreversible sorption may be occurring. Although wetlands commonly are expected to decrease fluxes of contaminants in riparian environments, enhanced attenuation of the leachate contaminants in the slough sediment porewater compared to the aquifer was not observed in this study. The lack of enhanced attenuation can be attributed to the fact that the anoxic plume, comprised largely of recalcitrant DOC and reduced inorganic constituents, interacted with anoxic slough sediments and porewaters, rather than encountering a change in redox conditions that could cause transformation reactions. Nevertheless, the attenuation processes in the narrow zone of groundwater/surface-water interaction were effective in reducing ammonium concentrations by a factor of about 3 during lateral transport across the slough and by a factor of 2 to 10 before release to the surface water. Slough porewater geochemistry also indicated that the slough could be a source of sulfate in dry conditions, potentially providing a terminal electron acceptor for natural attenuation of organic compounds in the leachate plume.","language":"English","publisher":"Elsevier","doi":"10.1016/j.jconhyd.2008.11.008","issn":"01697722","usgsCitation":"Lorah, M., Cozzarelli, I., and Böhlke, J., 2009, Biogeochemistry at a wetland sediment-alluvial aquifer interface in a landfill leachate plume: Journal of Contaminant Hydrology, v. 105, no. 3-4, p. 99-117, https://doi.org/10.1016/j.jconhyd.2008.11.008.","productDescription":"19 p.","startPage":"99","endPage":"117","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":243651,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":215824,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.jconhyd.2008.11.008"}],"volume":"105","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f157e4b0c8380cd4abd9","contributors":{"authors":[{"text":"Lorah, M.M.","contributorId":29002,"corporation":false,"usgs":true,"family":"Lorah","given":"M.M.","affiliations":[],"preferred":false,"id":448549,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Cozzarelli, I.M. 0000-0002-5123-1007","orcid":"https://orcid.org/0000-0002-5123-1007","contributorId":22343,"corporation":false,"usgs":true,"family":"Cozzarelli","given":"I.M.","affiliations":[],"preferred":false,"id":448548,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Böhlke, J.K. 0000-0001-5693-6455","orcid":"https://orcid.org/0000-0001-5693-6455","contributorId":96696,"corporation":false,"usgs":true,"family":"Böhlke","given":"J.K.","affiliations":[],"preferred":false,"id":448550,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Little is known about native communities in naturally fishless lakes in eastern North America, a region where fish stocking has led to a decline in these habitats. 2. Our study objectives were to: (i) characterise and compare macroinvertebrate communities in fishless lakes found in two biophysical regions of Maine (U.S.A.): kettle lakes in the eastern lowlands and foothills and headwater lakes in the central and western mountains; (ii) identify unique attributes of fishless lake macroinvertebrate communities compared to lakes with fish and (iii) develop a method to efficiently identify fishless lakes when thorough fish surveys are not possible. 3. We quantified macroinvertebrate community structure in the two physiographic fishless lake types (n = 8 kettle lakes; n = 8 headwater lakes) with submerged light traps and sweep nets. We also compared fishless lake macroinvertebrate communities to those in fish-containing lakes (n = 18) of similar size, location and maximum depth. We used non-metric multidimensional scaling to assess differences in community structure and t-tests for taxon-specific comparisons between lakes. 4. Few differences in macroinvertebrate communities between the two physiographic fishless lake types were apparent. Fishless and fish-containing lakes had numerous differences in macroinvertebrate community structure, abundance, taxonomic composition and species richness. Fish presence or absence was a stronger determinant of community structure in our study than differences in physical conditions relating to lake origin and physiography. 5. Communities in fishless lakes were more speciose and abundant than in fish-containing lakes, especially taxa that are large, active and free-swimming.

We identified six taxa unique to fishless lakes that are robust indicators of fish absence: Graphoderus liberus, Hesperocorixa spp., Dineutus spp., Chaoborus americanus, Notonecta insulata and Callicorixa spp. These taxa are collected most effectively with submerged light traps. 7.

This study used satellite-derived rainfall and other key weather variables derived from the Global Data Assimilation System to estimate and map the distribution of rainfall, actual evapotranspiration (ETa), and runoff. Daily water balance components were modelled in a grid-cell environment at 0·1 degree (∼10 km) spatial resolution for 7 years from 2001 through 2007. Annual maps of the key water balance components and derived variables such as runoff and ETa as a percent of rainfall were produced. Generally, the spatial patterns of rainfall and ETa indicate high values in the upstream watersheds (Uganda, southern Sudan, and southwestern Ethiopia) and low values in the downstream watersheds. However, runoff as a percent of rainfall is much higher in the Ethiopian highlands around the Blue Nile subwatershed. The analysis also showed the possible impact of land degradation in the Ethiopian highlands in reducing ETa magnitudes despite the availability of sufficient rainfall. Although the model estimates require field validation for the different subwatersheds, the runoff volume estimate for the Blue Nile subwatershed is within 7·0% of a figure reported from an earlier study. Further research is required for a thorough validation of the results and their integration with ecohydrologic models for better management of water and land resources in the various Nile Basin ecosystems.</span></p>","language":"English","publisher":"Wiley","doi":"10.1002/hyp.7364","issn":"08856087","usgsCitation":"Senay, G.B., Asante, K., and Artan, G.A., 2009, Water balance dynamics in the Nile Basin: Hydrological Processes, v. 23, no. 26, p. 3675-3681, https://doi.org/10.1002/hyp.7364.","productDescription":"7 p.","startPage":"3675","endPage":"3681","numberOfPages":"7","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":244730,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":216834,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/hyp.7364"}],"volume":"23","issue":"26","noUsgsAuthors":false,"publicationDate":"2009-08-26","publicationStatus":"PW","scienceBaseUri":"505bc7c2e4b08c986b32c5f2","contributors":{"authors":[{"text":"Senay, Gabriel B. 0000-0002-8810-8539 senay@usgs.gov","orcid":"https://orcid.org/0000-0002-8810-8539","contributorId":3114,"corporation":false,"usgs":true,"family":"Senay","given":"Gabriel","email":"senay@usgs.gov","middleInitial":"B.","affiliations":[{"id":223,"text":"Earth Resources Observation and Science (EROS) Center (Geography)","active":false,"usgs":true}],"preferred":true,"id":443581,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Asante, Kwabena 0000-0001-5408-1852","orcid":"https://orcid.org/0000-0001-5408-1852","contributorId":65948,"corporation":false,"usgs":true,"family":"Asante","given":"Kwabena","affiliations":[],"preferred":false,"id":443583,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Artan, Guleid A. 0000-0001-8409-6182 gartan@usgs.gov","orcid":"https://orcid.org/0000-0001-8409-6182","contributorId":2938,"corporation":false,"usgs":true,"family":"Artan","given":"Guleid","email":"gartan@usgs.gov","middleInitial":"A.","affiliations":[{"id":223,"text":"Earth Resources Observation and Science (EROS) Center (Geography)","active":false,"usgs":true}],"preferred":true,"id":443582,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The barite is contained in sedimentary sequences as old as Late Neoproterozoic and as young as Mississippian. If previously published data for other localities are considered, sulfur- and oxygen-isotope data are now available for deposits spanning a host-rock age range of Late Neoproterozoic to Triassic. On a ??34S versus ??18O diagram, many deposits show linear or concave-upward trends that project down toward the isotopic composition of seawater sulfate. The trends suggest that barite formed from seawater sulfate that had been isotopically modified to varying degrees. The ??34S versus ??18O patterns resemble patterns that have been observed in the modern oceans in pore water sulfate and water column sulfate in some anoxic basins. However, the closest isotopic analog is barite mineralization that occurs at fluid seeps on modern continental margins. Thus the data favor genetic models for the deposits in which barium was delivered by seafloor seeps over models in which barium was delivered by sedimentation of pelagic organisms. The isotopic variations within the deposits appear to reflect bacterial sulfate reduction operating at different rates and possibly with different electron donors, oxygen isotope exchange between reduction intermediates and H2O, and sulfate availability. Because they are isotopically heterogeneous, sediment-hosted stratiform barite deposits are of limited value in reconstructing the isotopic composition of ancient seawater sulfate.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geochimica et Cosmochimica Acta","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.gca.2008.10.011","issn":"00167","usgsCitation":"Johnson, C.A., Emsbo, P., Poole, F.G., and Rye, R.O., 2009, Sulfur- and oxygen-isotopes in sediment-hosted stratiform barite deposits: Geochimica et Cosmochimica Acta, v. 73, no. 1, p. 133-147, https://doi.org/10.1016/j.gca.2008.10.011.","startPage":"133","endPage":"147","numberOfPages":"15","costCenters":[],"links":[{"id":213303,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.gca.2008.10.011"},{"id":240915,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"73","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b9de7e4b08c986b31db78","contributors":{"authors":[{"text":"Johnson, C.

Five study areas in the southern Rocky Mountains with naturally acidic waters associated with porphyry mineralization were studied to document variations in water chemistry and processes that control the chemical variations. Study areas include the Upper Animas River watershed, East Alpine Gulch, Mount Emmons, and Handcart Gulch in Colorado and the Red River in New Mexico. Although host-rock lithologies in all these areas range from Precambrian gneisses to Cretaceous sedimentary units to Tertiary volcanic complexes, the mineralization is Tertiary in age and associated with intermediate to felsic composition, porphyritic plutons. Pyrite is ubiquitous, ranging from ???1 to >5 vol.%. Springs and headwater streams have pH values as low as 2.6, SO4 up to 3700 mg/L and high dissolved metal concentrations (for example: Fe up to 400 mg/L; Cu up to 3.5 mg/L; and Zn up to 14.4 mg/L). Intensity of hydrothermal alteration and presence of sulfides are the primary controls of water chemistry of these naturally acidic waters. Subbasins underlain by intensely hydrothermally altered lithologies are poorly vegetated and quite susceptible to storm-induced surface runoff. Within the Red River study area, results from a storm runoff study documented downstream changes in river chemistry: pH decreased from 7.80 to 4.83, alkalinity decreased from 49.4 to <1 mg/L, SO4 increased from 162 to 314 mg/L, dissolved Fe increased from to 0.011 to 0.596 mg/L, and dissolved Zn increased from 0.056 to 0.607 mg/L. Compared to mine drainage in the same study areas, the chemistry of naturally acidic waters tends to overlap but not reach the extreme concentrations of metals and acidity as some mine waters. The chemistry of waters draining these mineralized but unmined areas can be used to estimate premining conditions at sites with similar geologic and hydrologic conditions. For example, the US Geological Survey was asked to estimate premining ground-water chemistry at the Questa Mo mine, and the proximal analog approach was used because a mineralized but unmined area was located adjacent to the mine property. By comparing and contrasting water chemistry from different porphyry mineralized areas, this study not only documents the range in concentrations of constituents of interest but also provides insight into the primary controls of water chemistry.","language":"English","publisher":"Elsevier","doi":"10.1016/j.apgeochem.2008.11.014","issn":"08832","usgsCitation":"Verplanck, P., Nordstrom, D.K., Bove, D.J., Plumlee, G., and Runkel, R., 2009, Naturally acidic surface and ground waters draining porphyry-related mineralized areas of the Southern Rocky Mountains, Colorado and New Mexico: Applied Geochemistry, v. 24, no. 2, p. 255-267, https://doi.org/10.1016/j.apgeochem.2008.11.014.","productDescription":"13 p.","startPage":"255","endPage":"267","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":241267,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":213621,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.apgeochem.2008.11.014"}],"volume":"24","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a6388e4b0c8380cd7253d","contributors":{"authors":[{"text":"Verplanck, P.

However, very few in situ measurements of electrical current above thunderstorms have been successfully obtained. In this paper, we present dc to very low frequency electric fields and atmospheric conductivity measured in the stratosphere (30-35??km altitude) above an active thunderstorm in southeastern Brazil. From these measurements, we estimate the mean quasi-static conduction current during the storm period to be 2.5 ?? 1.25??A. Additionally, we examine the transient conduction currents following a large positive cloud-to-ground (+ CG) lightning flash and typical - CG flashes. We find that the majority of the total current is attributed to the quasi-static thundercloud charge, rather than lightning, which supports the classical Wilson model for the global electrical circuit.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Atmospheric Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.atmosres.2008.03.026","issn":"01698","usgsCitation":"Thomas, J., Holzworth, R., and McCarthy, M., 2009, In situ measurements of contributions to the global electrical circuit by a thunderstorm in southeastern Brazil: Atmospheric Research, v. 91, no. 2-4, p. 153-160, https://doi.org/10.1016/j.atmosres.2008.03.026.","startPage":"153","endPage":"160","numberOfPages":"8","costCenters":[],"links":[{"id":213677,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.atmosres.2008.03.026"},{"id":241328,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"91","issue":"2-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a39a5e4b0c8380cd619bd","contributors":{"authors":[{"text":"Thomas, J.N.","contributorId":20988,"corporation":false,"usgs":false,"family":"Thomas","given":"J.N.","email":"","affiliations":[],"preferred":false,"id":437913,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Holzworth, R.H.","contributorId":84571,"corporation":false,"usgs":true,"family":"Holzworth","given":"R.H.","affiliations":[],"preferred":false,"id":437915,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"McCarthy, M.P.","contributorId":33932,"corporation":false,"usgs":true,"family":"McCarthy","given":"M.P.","email":"","affiliations":[],"preferred":false,"id":437914,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Neotropical migrant birds show a clear preference for stopover habitats with ample food supplies; yet, the proximate cues underlying these decisions remain unclear. 2. For insectivorous migrants, cues associated with vegetative phenology (e.g. flowering, leaf flush, and leaf loss) may reliably predict the availability of herbivorous arthropods. Here we examined whether migrants use the phenology of five tree species to choose stopover locations, and whether phenology accurately predicts food availability. 3. Using a combination of experimental and observational evidence, we show migrant populations closely track tree phenology, particularly the flowering phenology of honey mesquite (Prosopis glandulosa), and preferentially forage in trees with more flowers. Furthermore, the flowering phenology of honey mesquite reliably predicts overall arthropod abundance as well as the arthropods preferred by migrants for food. 4. Together, these results suggest that honey mesquite flowering phenology is an important cue used by migrants to assess food availability quickly and reliably, while in transit during spring migration. ?? 2008 The Authors.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Animal Ecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1365-2656.2008.01464.x","issn":"00218","usgsCitation":"McGrath, L., van Riper, C., and Fontaine, J., 2009, Flower power: Tree flowering phenology as a settlement cue for migrating birds: Journal of Animal Ecology, v. 78, no. 1, p. 22-30, https://doi.org/10.1111/j.1365-2656.2008.01464.x.","startPage":"22","endPage":"30","numberOfPages":"9","costCenters":[],"links":[{"id":240851,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":213245,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1365-2656.2008.01464.x"}],"volume":"78","issue":"1","noUsgsAuthors":false,"publicationDate":"2008-12-11","publicationStatus":"PW","scienceBaseUri":"505a125fe4b0c8380cd542a1","contributors":{"authors":[{"text":"McGrath, L.J.","contributorId":92493,"corporation":false,"usgs":true,"family":"McGrath","given":"L.J.","email":"","affiliations":[],"preferred":false,"id":439479,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"van Riper, Charles III 0000-0003-1084-5843 charles_van_riper@usgs.gov","orcid":"https://orcid.org/0000-0003-1084-5843","contributorId":169488,"corporation":false,"usgs":true,"family":"van Riper","given":"Charles","suffix":"III","email":"charles_van_riper@usgs.gov","affiliations":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"preferred":false,"id":439478,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Fontaine, J.J.","contributorId":37940,"corporation":false,"usgs":true,"family":"Fontaine","given":"J.J.","email":"","affiliations":[],"preferred":false,"id":439477,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Surrounded by a mosaic of open space conservation easements and public wildlife areas, it is one of the only watersheds in this urbanized estuary that is protected from its headwaters to the bay. Tolay Lake is a seasonal, spring-fed lake found in the upper watershed that historically extended over 120 ha. Although the lakebed was farmed since the early 1860s, the majority of the lakebed was recently acquired by the Sonoma County Regional Parks Department to restore its natural habitat values. As part of the restoration planning process, we produced a digital elevation model (DEM) of the historic extent of Tolay Lake by integrating terrestrial LiDAR (light detection and ranging) and stereo photogrammetry datasets, and real-time kinematic (RTK) global positioning system (GPS) surveys. We integrated the data, generated a DEM of the lakebed and upland areas, and analyzed errors. The accuracy of the composite DEM was verified using spot elevations obtained from the RTK GPS. Thus, we found that by combining photogrammetry, terrestrial LiDAR, and RTK GPS, we created an accurate baseline elevation map to use in watershed restoration planning and design.</p>","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"Planning for an uncertain future - Monitoring, integration, and adaptation","largerWorkSubtype":{"id":5,"text":"USGS Numbered Series"},"conferenceTitle":"Third interagency conference on research in the watersheds","conferenceDate":"September 8-11, 2008","conferenceLocation":"Estes Park, CO","language":"English","publisher":"U.S Geological Survey","publisherLocation":"Reston, VA","usgsCitation":"Woo, I., Storesund, R., Takekawa, J.Y., Gardiner, R.J., and Ehret, S., 2009, Integrating terrestrial LiDAR and stereo photogrammetry to map the Tolay lakebed in northern San Francisco Bay, <i>in</i> Planning for an uncertain future - Monitoring, integration, and adaptation, Estes Park, CO, September 8-11, 2008, p. 279-284.","productDescription":"6 p.","startPage":"279","endPage":"284","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-010725","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":328099,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":328098,"rank":1,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/sir/2009/5049/pdf/Woo.pdf"}],"country":"United States","state":"California","otherGeospatial":"northern San Francisco Bay, Tolay Lake","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -122.52725601196288,\n              38.1975848123397\n            ],\n            [\n              -122.51,\n              38.1975848123397\n            ],\n            [\n              -122.51,\n              38.21748069161304\n            ],\n            [\n              -122.52725601196288,\n              38.21748069161304\n            ],\n            [\n              -122.52725601196288,\n              38.1975848123397\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"57c7ffb4e4b0f2f0cebfc27e","contributors":{"authors":[{"text":"Woo, Isa 0000-0002-8447-9236 iwoo@usgs.gov","orcid":"https://orcid.org/0000-0002-8447-9236","contributorId":2524,"corporation":false,"usgs":true,"family":"Woo","given":"Isa","email":"iwoo@usgs.gov","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":647598,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Storesund, Rune Rune","contributorId":121326,"corporation":false,"usgs":true,"family":"Storesund","given":"Rune","suffix":"Rune","email":"","affiliations":[],"preferred":false,"id":647599,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Takekawa, John Y. 0000-0003-0217-5907 john_takekawa@usgs.gov","orcid":"https://orcid.org/0000-0003-0217-5907","contributorId":176168,"corporation":false,"usgs":true,"family":"Takekawa","given":"John","email":"john_takekawa@usgs.gov","middleInitial":"Y.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":false,"id":647600,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Gardiner, Rachel J.","contributorId":174164,"corporation":false,"usgs":false,"family":"Gardiner","given":"Rachel","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":647601,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Ehret, Steve Steve","contributorId":121092,"corporation":false,"usgs":true,"family":"Ehret","given":"Steve","suffix":"Steve","email":"","affiliations":[],"preferred":false,"id":647602,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}
