Based on stratigraphic correlation and diagnostic artifact seriation, Suwannee-age sites have been relatively dated from ??? 10,900 14C yr B.P to ??? 10,500 14C yr B.P. Clovis-like traits on the Suwannee points and other stone tools from the Ryan/Harley site suggest it dates to the earlier end of the Suwannee timeframe. The currently inundated site is partially buried beneath a sediment column located in a swamp forest and partially exposed in a side channel section of the Wacissa River, Jefferson County, Florida. Research done prior to this analysis determined that the artifact assemblage appeared to be unsorted and was contained in a midden-like unit. Our purpose here is to assess the issue of site integrity further. Unconsolidated sediment samples collected from the artifact-bearing horizon and from horizons immediately above and below the artifact horizon were analyzed using granulometric techniques. Arithmetic probability plots of the grain-size distributions show that the sediments were transported and deposited by fluvial processes. Thus, the Suwannee points and associated artifacts, and faunal remains appear to have accumulated during a time of subaerial exposure perhaps after a regional water-table decline, and have remained largely or essentially intact, with little or no postdepositional reworking. The artifacts and faunal remains recovered from the artifact-bearing horizon at Ryan/Harley are distributed randomly, showing no sign of sorting. In the fossil suite, two articulated white-tailed deer (Odocoileus virginianus) vertebra were recovered in situ. The unsorted nature of artifacts and articulated faunal remains that are contained within the fluvially deposited sediments suggests the Suwannee point level of the Ryan/Harley site has remained undisturbed since original deposition. ?? 2006 Wiley Periodicals, Inc.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geoarchaeology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1002/gea.20109","issn":"08836353","usgsCitation":"Balsillie, J.H., Means, G., and Dunbar, J., 2006, The Ryan/Harley site: Sedimentology of an inundated Paleoindian site in north Florida: Geoarchaeology, v. 21, no. 4, p. 363-391, https://doi.org/10.1002/gea.20109.","startPage":"363","endPage":"391","numberOfPages":"29","costCenters":[],"links":[{"id":211870,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/gea.20109"},{"id":239243,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"21","issue":"4","noUsgsAuthors":false,"publicationDate":"2006-03-03","publicationStatus":"PW","scienceBaseUri":"505ba8c5e4b08c986b321e35","contributors":{"authors":[{"text":"Balsillie, J.

The goal of this study was to examine relationships among characteristics of the environment, Tubifex tubifex (the alternate host) populations, and rainbow trout whirling disease risk in the Madison River. Environmental characteristics were measured in side channels of the Madison River, and differences were described with a principal components analysis. The density of T. tubifex, the prevalence of infection in T. tubifex, and the density of infected T. tubifex were determined for the side channels using benthic core samples and examination of live tubificids for infection. The site-specific contribution to whirling disease risk in the side channels was determined using in situ exposures of sentinel rainbow trout. Regression analyses were used to determine correlations among these characteristics. Side channels differed in site-specific contribution to rainbow trout whirling disease risk, which was positively correlated to the density of infected T. tubifex. Side channels with fine sediments and lower water temperatures made greater site-specific contribution to whirling disease risk and had higher densities of infected T. tubifex than side channels with coarser sediments and higher temperatures. The ability to characterize areas of high whirling disease risk is essential for improving our understanding of the dynamics of M. cerebralis such that appropriate management strategies can be implemented. In addition, this study provides a model of how the disease ecology of complex aquatic parasites can be examined when the influential processes operate on different spatial scales. ?? 2006 by the Ecological Society of America.</p>","language":"English","publisher":"Ecological Society of America","doi":"10.1890/1051-0761(2006)016[0770:ROMCIT]2.0.CO;2","issn":"10510761","usgsCitation":"Krueger, R., Kerans, B., Vincent, E., and Rasmussen, C., 2006, Risk of Myxobolus cerebralis infection to rainbow trout in the Madison River, Montana, USA: Ecological Applications, v. 16, no. 2, p. 770-783, https://doi.org/10.1890/1051-0761(2006)016[0770:ROMCIT]2.0.CO;2.","productDescription":"14 p.","startPage":"770","endPage":"783","numberOfPages":"14","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"links":[{"id":239352,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Montana","otherGeospatial":"Madison River","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -111.64169311523438,\n              45.0938831252118\n            ],\n            [\n              -111.6925048828125,\n              45.08321794926837\n            ],\n            [\n              -111.69937133789062,\n              45.00365115687189\n            ],\n            [\n              -111.57302856445312,\n              44.83347388333049\n            ],\n            [\n              -111.43569946289062,\n              44.79450545288309\n            ],\n            [\n              -111.41921997070312,\n              44.822760189927365\n            ],\n            [\n              -111.43569946289062,\n              44.85100108620397\n            ],\n            [\n              -111.57852172851562,\n              44.93175198383987\n            ],\n            [\n              -111.64993286132812,\n              45.03956694724904\n            ],\n            [\n              -111.64993286132812,\n              45.08515722028692\n            ],\n            [\n              -111.64169311523438,\n              45.0938831252118\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"16","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505aad96e4b0c8380cd86f23","contributors":{"authors":[{"text":"Krueger, R.C.","contributorId":32350,"corporation":false,"usgs":true,"family":"Krueger","given":"R.C.","email":"","affiliations":[],"preferred":false,"id":427804,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kerans, B.L.","contributorId":93610,"corporation":false,"usgs":true,"family":"Kerans","given":"B.L.","email":"","affiliations":[],"preferred":false,"id":427807,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Vincent, E.R.","contributorId":64889,"corporation":false,"usgs":true,"family":"Vincent","given":"E.R.","email":"","affiliations":[],"preferred":false,"id":427805,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Rasmussen, C.","contributorId":66392,"corporation":false,"usgs":true,"family":"Rasmussen","given":"C.","email":"","affiliations":[],"preferred":false,"id":427806,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Low flows are often important ecologically. Numerical simulations were used to assess how textural heterogeneity of an alluvial system influences river seepage and low flows. The Cosumnes River in California was used as a test case. Declining fall flows in the Cosumnes River have threatened Chinook salmon runs. A ground water-surface water model for the lower river basin was developed, which incorporates detailed geostatistical simulations of aquifer heterogeneity. Six different realizations of heterogeneity and a homogenous model were run for a 3-year period. Net annual seepage from the river was found to be similar among the models. However, spatial distribution of seepage along the channel, water table configuration and the level of local connection, and disconnection between the river and aquifer showed strong variations among the different heterogeneous models. Most importantly, the heterogeneous models suggest that river seepage losses can be reduced by local reconnections, even when the regional water table remains well below the riverbed. The percentage of river channel responsible for 50% of total river seepage ranged from 10% to 26% in the heterogeneous models as opposed to 23% in the homogeneous model. Differences in seepage between the models resulted in up to 13 d difference in the number of days the river was open for salmon migration during the critical fall months in one given year.

The research is based on remote sensing and geographic information techniques, as well as statistical analysis. High-resolution satellite image data were used to analyse the 1974-2000 period, and very low-resolution satellite image data were used for the 1997-2001 period. The long-term analysis (1974-2000) indicated that there were temporal changes in the surface area of the Cuitzeo Lake and that these changes were related to precipitation and temperatures that occurred in the previous year. Short-term monitoring (1997-2001) showed that the Cuitzeo Lake surface is lowering. Field observations demonstrated also that yearly desiccation is recurrent, particularly, in the western section of the lake. Results suggested that this behaviour was probably due to a drought period in the basin that began in the mid 1990s. Regression models constructed from long-term data showed that fluctuations of lake level can be estimated by monthly mean precipitation and temperatures of the previous year. ??

In this study, U(VI) reactivity and surface speciation on a poorly crystalline aluminosilicate mineral, synthetic imogolite, were investigated using batch adsorption experiments, X-ray absorption spectroscopy (XAS), and surface complexation modeling. U(VI) uptake on imogolite surfaces was greatest at pH ∼7–8 (<i>I</i>&nbsp;=&nbsp;0.1&nbsp;M NaNO<sub>3</sub><span>&nbsp;</span>solution, suspension density&nbsp;=&nbsp;0.4&nbsp;g/L [U(VI)]<sub>i</sub>&nbsp;=&nbsp;0.01–30&nbsp;μM, equilibration with air).

Beachcast carcasses represent an unknown fraction of at-sea mortalities. While a variety of physical (e.g., water temperature) and biological (e.g., decomposition) factors as well as the distribution of animals and their mortality sources likely affect the probability of carcass stranding, physical oceanography plays a major role in where and when carcasses strand. Here, we evaluate the influence of nearshore physical oceanographic and wind regimes on sea turtle strandings to decipher seasonal trends and make qualitative predictions about stranding patterns along oceanfront beaches. We use results from oceanic drift-bottle experiments to check our predictions and provide an upper limit on stranding proportions. We compare predicted current regimes from a 3D physical oceanographic model to spatial and temporal locations of both sea turtle carcass strandings and drift bottle landfalls. Drift bottle return rates suggest an upper limit for the proportion of sea turtle carcasses that strand (about 20%). In the South Atlantic Bight, seasonal development of along-shelf flow coincides with increased numbers of strandings of both turtles and drift bottles in late spring and early summer. The model also predicts net offshore flow of surface waters during winter - the season with the fewest relative strandings. The drift bottle data provide a reasonable upper bound on how likely carcasses are to reach land from points offshore and bound the general timeframe for stranding post-mortem (< two weeks).

It flowed 10 km from its vent area to the Little Colorado River, where it cascaded into and filled a 65-m-deep canyon to form the Grand Falls lava dam. Lava continued ???25 km downstream and ???1 km onto the far rim beyond where the canyon was filled. Subsequent fluvial sedimentation filled the reservoir behind the dam, and eventually the river established a channel along the margin of the lava flow to the site where water falls back into the pre-eruption canyon. The ca. 150 ka age of the Grand Falls flow provided by whole-rock K-Ar analysis in the 1970s is inconsistent with the preservation of centimeter-scale flow-top features on the surface of the flow and the near absence of physical and chemical weathering on the flow downstream of the falls. The buried Little Colorado River channel and the present-day channel are at nearly the same elevation, indicating that very little, if any, regional downcutting has occurred since emplacement of the flow. Newly applied dating techniques better define the age of the lava dam. Infrared-stimulated luminescence dating of silty mudstone baked by the lava yielded an age of 19.6 ?? 1.2 ka. Samples from three noneroded or slightly eroded outcrops at the top of the lava flow yielded 3He cosmogenic ages of 16 ?? 1 ka, 17 ?? 1 ka, and 20 ?? 1 ka. A mean age of 8 ?? 19 ka was obtained from averaging four samples using the 40Ar/39Ar step-heating method. Finally, paleomagnetic directions in lava samples from two sites at Grand Falls and one at the vent area are nearly identical and match the curve of magnetic secular variation at ca. 15 ka, 19 ka, 23 ka, and 28 ka. We conclude that the Grand Falls flow was emplaced at ca. 20 ka. ?? 2006 Geological Society of America.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geological Society of America Bulletin","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1130/B25814.1","issn":"00167606","usgsCitation":"Duffield, W., Riggs, N., Kaufman, D., Champion, D., Fenton, C., Forman, S., McIntosh, W., Hereford, R., Plescia, J., and Ort, M., 2006, Multiple constraints on the age of a Pleistocene lava dam across the Little Colorado River at Grand Falls, Arizona: Geological Society of America Bulletin, v. 118, no. 3-4, p. 421-429, https://doi.org/10.1130/B25814.1.","startPage":"421","endPage":"429","numberOfPages":"9","costCenters":[],"links":[{"id":211887,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1130/B25814.1"},{"id":239261,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"118","issue":"3-4","noUsgsAuthors":false,"publicationDate":"2006-03-13","publicationStatus":"PW","scienceBaseUri":"505a6061e4b0c8380cd713fa","contributors":{"authors":[{"text":"Duffield, W.","contributorId":42715,"corporation":false,"usgs":true,"family":"Duffield","given":"W.","affiliations":[],"preferred":false,"id":426313,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Riggs, N.","contributorId":26878,"corporation":false,"usgs":true,"family":"Riggs","given":"N.","affiliations":[],"preferred":false,"id":426311,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kaufman, D.","contributorId":96481,"corporation":false,"usgs":true,"family":"Kaufman","given":"D.","affiliations":[],"preferred":false,"id":426317,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Champion, D.","contributorId":103012,"corporation":false,"usgs":true,"family":"Champion","given":"D.","email":"","affiliations":[],"preferred":false,"id":426318,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Fenton, C.","contributorId":85399,"corporation":false,"usgs":true,"family":"Fenton","given":"C.","email":"","affiliations":[],"preferred":false,"id":426315,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Forman, S.","contributorId":94497,"corporation":false,"usgs":true,"family":"Forman","given":"S.","email":"","affiliations":[],"preferred":false,"id":426316,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"McIntosh, W.","contributorId":29635,"corporation":false,"usgs":true,"family":"McIntosh","given":"W.","affiliations":[],"preferred":false,"id":426312,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Hereford, R.","contributorId":84437,"corporation":false,"usgs":true,"family":"Hereford","given":"R.","email":"","affiliations":[],"preferred":false,"id":426314,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Plescia, J.","contributorId":20500,"corporation":false,"usgs":true,"family":"Plescia","given":"J.","affiliations":[],"preferred":false,"id":426310,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Ort, M.","contributorId":11410,"corporation":false,"usgs":true,"family":"Ort","given":"M.","affiliations":[],"preferred":false,"id":426309,"contributorType":{"id":1,"text":"Authors"},"rank":10}]}}

Core sites were chosen to reflect a matrix of variable water depths, proximity to the Mississippi River mouth as the primary source for terrigenous particles, and extent and duration of summertime water column hypoxia. The vertical distribution of 239,240Pu and 210Pbxs (= 210Pbtotal - 226Ra) provided reliable geochronological age constraints to develop models for mass accumulation rates and historic trace element inputs and variations. Mass accumulation rates ranged from 0.27 to 0.87 g cm-2 yr-1 and were internally consistent using either 210Pbxs or 239,240Pu. Measured inventories of 137Cs, 239,240Pu, and 210Pbxs were compared to atmospheric deposition rates to quantify potential sediment focusing or winnowing. Observed variability in calculated mass accumulation rates may be attributed foremost to site-specific proximity to the river mouth (i.e., sediment source), variability in water depth, and enhanced sediment focusing at the Mississippi River canyon site. Trace element concentrations were first normalized to Al, and then Al-normalized enrichment factors (ANEF) were calculated based on preanthropogenic and crustal trace element abundances. These ANEFs were typically > 1 for V and Ba, while for most other elements studied, either no enrichment or depletion was observed. The enrichment of Ba may be related, in part, to the seasonal occurrence of oxygen-depleted subsurface waters off the Mississippi River delta, as well as being an ubiquitous by-product of the petroleum industry. ?? 2006 Estuarine Research Federation.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Estuaries and Coasts","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"15592723","usgsCitation":"Swarzenski, P., Baskaran, M., Rosenbauer, R., and Orem, W., 2006, Historical trace element distribution in sediments from the Mississippi River delta: Estuaries and Coasts, v. 29, no. 6 B, p. 1094-1107.","startPage":"1094","endPage":"1107","numberOfPages":"14","costCenters":[],"links":[{"id":236603,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"29","issue":"6 B","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a31a2e4b0c8380cd5e0c1","contributors":{"authors":[{"text":"Swarzenski, P.W. 0000-0003-0116-0578","orcid":"https://orcid.org/0000-0003-0116-0578","contributorId":29487,"corporation":false,"usgs":true,"family":"Swarzenski","given":"P.W.","affiliations":[],"preferred":false,"id":418808,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Baskaran, M.","contributorId":96627,"corporation":false,"usgs":true,"family":"Baskaran","given":"M.","affiliations":[],"preferred":false,"id":418811,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Rosenbauer, R.J.","contributorId":37320,"corporation":false,"usgs":true,"family":"Rosenbauer","given":"R.J.","email":"","affiliations":[],"preferred":false,"id":418809,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Orem, W.

Denitrification activities ranged from 0 and 800 ng-N gsed-1 d-1 with large variations observed within short distances (<50 m) along stream reaches. A log-normal probability distribution described the range in denitrification activities and was used to define low (16% of the probability distributibn), medium (68%), and high (16%) denitrification potential groups. Denitrifying bacteria were quantified using a competitive polymerase chain reaction (cPCR) technique that amplified the nirK gene that encodes for nitrite reductase. Results showed a range of nirK quantities from 103 to 107 gene-copy-number gsed.-1 A nonparametric statistical test showed no significant difference in nirK quantifies among stream reaches, but revealed that samples with a high denitrification potential had significantly higher nirK quantities. Denitrification activity was positively correlated with nirK quantities with scatter in the data that can be attributed to varying environmental conditions along stream reaches. Dimensional analysis was used to evaluate denitrification activities according to environmental variables that describe fluid-flow properties, nitrate and organic material quantities, and dissolved oxygen flux. Buckingham's pi theorem was used to generate dimensionless groupings and field data were used to determine scaling parameters. The resulting expressions between dimensionless NO3- flux and dimensionless groupings of environmental variables showed consistent scaling, which indicates that the subreach variability in denitrification rates can be predicted by the controlling physical, chemical, and microbiological conditions.

Radar tomography data were collected using 100‐MHz electric‐dipole antennae before and during steam injection to evaluate whether cross‐hole radar methods could detect changes in medium properties resulting from the steam injection. Cross‐hole levelrun profiles, in which transmitting and receiving antennae are positioned at a common depth, were made before and after the collection of each full tomography data set to check the stability of the radar instruments. Before tomographic inversion, the levelrun profiles were used to calibrate the radar tomography data to compensate for changes in traveltime and antenna power caused by instrument drift. Observed changes in cross‐hole radar traveltime and attenuation before and during steam injection were small. Slowness‐ and attenuation‐difference tomograms indicate small increases in radar slowness and attenuation at depths greater than about 22 m below the surface, consistent with increases in water temperature observed in the boreholes used for the tomography. Based on theoretical modelling results, increases in slowness and attenuation are interpreted as delineating zones where steam injection heating increased the electrical conductivity of the limestone matrix and fluid.

Many alternate parameterizations for correction coefficients for three PET equations are presented, covering a wide range of possible data-availability scenarios. At nine sites in the wetland Everglades of south Florida, USA, the relatively complex PET Penman equation was corrected to daily total AET with smaller standard errors than the PET simple and Priestley-Taylor equations. The simpler equations, however, required less data (and thus less funding for instrumentation), with the possibility of being corrected to AET with slightly larger, comparable, or even smaller standard errors. Air temperature generally corrected PET simple most effectively to wetland AET, while wetland stage and humidity generally corrected PET Priestley-Taylor and Penman most effectively to wetland AET. Stage was identified for PET Priestley-Taylor and Penman as the data type with the most correction ability at sites that are dry part of each year or dry part of some years. Finally, although surface water generally was readily available at each monitoring site, AET was not occurring at potential rates, as conceptually expected under well-watered conditions. Apparently, factors other than water availability, such as atmospheric and stomata resistances to vapor transport, also were limiting the PET rate. ?? 2006, The Society of Wetland Scientists.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Wetlands","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1672/0277-5212(2006)26[528:ACFEAW]2.0.CO;2","issn":"02775212","usgsCitation":"Shoemaker, W., and Sumner, D.M., 2006, Alternate corrections for estimating actual wetland evapotranspiration from potential evapotranspiration: Wetlands, v. 26, no. 2, p. 528-543, https://doi.org/10.1672/0277-5212(2006)26[528:ACFEAW]2.0.CO;2.","startPage":"528","endPage":"543","numberOfPages":"16","costCenters":[],"links":[{"id":236591,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":209855,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1672/0277-5212(2006)26[528:ACFEAW]2.0.CO;2"}],"volume":"26","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e97ce4b0c8380cd482f6","contributors":{"authors":[{"text":"Shoemaker, W.

Dikes were later constructed to impound seasonal sheet surface flows for waterfowl management. The US Fish and Wildlife Service, which now manages the wetland as part of Seney National Wildlife Refuge, sought to redirect water flows from impounded C-3 Pool to reduce erosion in downstream Walsh Ditch, reduce ground-water losses into the ditch, and restore sheet flows of surface water to the peatland. A water budget was developed for C-3 Pool, which serves as the central receiving and distribution body for water in the affected wetland. Surface-water inflows and outflows were measured in associated ditches and natural creeks, ground-water flows were estimated using a network of wells and piezometers, and precipitation and evaporation/evapotranspiration components were estimated using local meteorological data. Water budgets for the 1999 springtime peak flow period and the 1999 water year were used to estimate required releases of water from C-3 Pool via outlets other than Walsh Ditch and to guide other restoration activities. Refuge managers subsequently used these results to guide restoration efforts, including construction of earthen dams in Walsh Ditch upslope from the pool to stop surface flow, installation of new water-control structures to redirect surface water to sheet flow and natural creek channels, planning seasonal releases from C-3 Pool to avoid erosion in natural channels, stopping flow in downslope Walsh Ditch to reduce erosion, and using constructed earthen dams and natural beaver dams to flood the ditch channel below C-3 Pool. Interactions between ground water and surface water are critical for maintaining ecosystem processes in many wetlands, and management actions directed at restoring either ground- or surface-water flow patterns often affect both of these components of the water budget. This approach could thus prove useful in guiding restoration efforts in many hydrologically altered and managed wetlands worldwide.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Hydrology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.jhydrol.2005.07.026","usgsCitation":"Wilcox, D.A., Sweat, M.J., Carlson, M.L., and Kowalski, K., 2006, A water-budget approach to restoring a sedge fen affected by diking and ditching: Journal of Hydrology, v. 320, no. 3-4, p. 501-517, https://doi.org/10.1016/j.jhydrol.2005.07.026.","productDescription":"p. 501-517","startPage":"501","endPage":"517","numberOfPages":"16","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":477565,"rank":1,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"http://hdl.handle.net/20.500.12648/2319","text":"External Repository"},{"id":133703,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":266667,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.jhydrol.2005.07.026"}],"volume":"320","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b16e4b07f02db6a51de","contributors":{"authors":[{"text":"Wilcox, Douglas A.","contributorId":36880,"corporation":false,"usgs":true,"family":"Wilcox","given":"Douglas","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":310417,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sweat, Michael J. mjsweat@usgs.gov","contributorId":356,"corporation":false,"usgs":true,"family":"Sweat","given":"Michael","email":"mjsweat@usgs.gov","middleInitial":"J.","affiliations":[{"id":5050,"text":"WY-MT Water Science Center","active":true,"usgs":true}],"preferred":true,"id":310415,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Carlson, Martha L.","contributorId":50869,"corporation":false,"usgs":true,"family":"Carlson","given":"Martha","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":310418,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Kowalski, Kurt P. 0000-0002-8424-4701 kkowalski@usgs.gov","orcid":"https://orcid.org/0000-0002-8424-4701","contributorId":3768,"corporation":false,"usgs":true,"family":"Kowalski","given":"Kurt P.","email":"kkowalski@usgs.gov","affiliations":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"preferred":true,"id":310416,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

A sample of 84 terns from the San Francisco Bay estuary were captured or collected, measured, and the sex of 40 female and 44 male terns was confirmed by genetic analyses or via necropsy. Male Forster's Terns were larger than females for 7 of 9 morphological measurements, with head-bill length showing the least amount of overlap between the sexes, followed by culmen length and culmen depth at the gonys. Sexual size dimorphism was greatest with retrix R6 length, followed by culmen width, and culmen depth. A discriminant function including only head-bill length accurately sexed 82% of Forster's Terns, whereas a second discriminant function incorporating both head-bill length and culmen depth at the gonys increased sexing accuracy to 87%. When we used a 75% posterior probability or greater of accurately sexing Forster's Terns, we excluded only 18% of the sample that overlapped and accurately sexed 94% of the remaining individuals.

Improvements in live-well conditions (reduction in water temperature by 2-5??C; addition of NaCl; continuous aeration) significantly reduced initial mortality of largemouth bass from 7% to 3% (F 1,11 = 10.29, P < 0.01). However, postrelease mortality of fish held for 5 d in net-pens or raceways was not reduced by the improved live-well conditions and averaged 76% for all tournament fish (F1,11 = 0.09, P = 0.77). The percentage of angler-caught fish infected with LMBV at the end of tournaments (14%) was significantly higher (P = 0.05) than the percentage infected in the general population (7%). The percentage of LMBV-infected fish increased during the post-tournament retention period to 64% for fish from live wells with improved conditions and 70% for fish from control live wells. Reference fish collected by electrofishing and held with tournament fish for 5 d also had high mortality (59%) and LMBV prevalence (47%), but these variables were significantly lower than those for tournament fish (mortality: F 2,30 = 3.63, P = 0.04; prevalence [Cochran-Mantel-Haenszel test]: P < 0.01). Many of the fish also had bacterial diseases during the post-tournament period, so the effect of LMBV on postrelease mortality could not be determined. However, the higher postrelease mortality of tournament and reference fish in our study relative to that observed in previous tournaments on lakes presumed free of LMBV suggests that this newly discovered pathogen influences measurement of post-tournament mortality. Increases in LMBV prevalence after typical fishing tournaments without prolonged post-tournament fish confinement will probably be lower than those we observed, but further research on the effects of LMBV on fish released from tournaments is warranted. ??

Mini-TES has observed hundreds of rocks along the rover's traverse into the Columbia Hills, yielding information on their distribution, bulk mineralogy, and the potential role of water at the site. Although dust in various forms produces contributions to the spectra, we have established techniques for dealing with it. All of the rocks encountered on the plains traverse from the lander to the base of the Columbia Hills share common spectral features consistent with an olivine-rich basaltic rock known as Adirondack Class. Beginning at the base of the West Spur of the Columbia Hills and across its length, the rocks are spectrally distinct from the plains but can be grouped into a common type called Clovis Class. These rocks, some of which appear as in-place outcrop, are dominated by a component whose spectral character is consistent with unaltered basaltic glass despite evidence from other rover instruments for significant alteration. The northwest flank of Husband Hill is covered in float rocks known as Wishstone Class with spectral features that can be attributed uniquely to plagioclase feldspar, a phase that represents more than half of the bulk mineralogy. Rare exceptions are three classes of basaltic \"exotics\" found scattered across Husband Hill that may represent impact ejecta and/or float derived from local intrusions within the hills. The rare outcrops observed on Husband Hill display distinctive spectral characteristics. The outcrop called Peace shows a feature attributable to molecular bound water, and the outcrop that hosts the rock called Watchtower displays a dominant basaltic glass component. Despite evidence from the rover's payload for significant alteration of some of the rocks, no unambiguous detection of crystalline phyllosilicates or other secondary silicates has been observed by Mini-TES. The mineralogical results supplied by Mini-TES provide no clear evidence that a lake once existed in Gusev Crater.

Micrometer-scale growth layering in the minerals was imaged using a cathodoluminescence detector on a scanning electron microscope. Determinations of the chemistry, ages, and delta oxygen-18 (??18O) values of the growth layers were conducted by electron microprobe analysis and secondary ion mass spectrometry techniques at spatial resolutions of 2 to about 20 micrometers (??m) and 25 to 40 ??m, respectively. Growth rates for the last 300 thousand years (k.y.) calculated from about 300 new high-resolution uranium-series ages range from approximately 0.5 to 1.5 ??m/k.y. for 1- to 3-centimeter-thick coatings, whereas coatings less than about 1-centimeter-thick have growth rates less than 0.5 ??m/k.y. At the depth of the proposed repository, correlations of uranium concentration and ??18O values with regional climate records indicate that unsaturated zone percolation and seepage water chemistries have responded to changes in climate during the last several hundred thousand years.","largerWorkTitle":"Proceedings of the 11th International High Level Radioactive Waste Management Conference, IHLRWM","conferenceTitle":"11th International High Level Radioactive Waste Management Conference","conferenceDate":"30 April 2006 through 4 May 2006","conferenceLocation":"Las Vegas, NV","language":"English","isbn":"0894486918; 9780894486913","usgsCitation":"Whelan, J.F., Paces, J., Neymark, L., Schmitt, A., and Grove, M., 2006, Impact of quaternary climate on seepage at Yucca Mountain, Nevada, <i>in</i> Proceedings of the 11th International High Level Radioactive Waste Management Conference, IHLRWM, v. 2006, Las Vegas, NV, 30 April 2006 through 4 May 2006, p. 199-206.","startPage":"199","endPage":"206","numberOfPages":"8","costCenters":[],"links":[{"id":236570,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"2006","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a38c5e4b0c8380cd616b0","contributors":{"authors":[{"text":"Whelan, J.

A downward-looking pulse-coherent acoustic Doppler profiler (PCADP) and two acoustic-Doppler velocimeters (field version; ADVFs) were deployed on a tripod at 9-m water depth. Measurements from these instruments were used to estimate shear velocity with (1) a modified eddy-correlation (EC) technique, (2) the log-profile (LP) method, and (3) a dissipation-rate method. Although values produced by the three methods agreed reasonably well (within their broad ranges of uncertainty), there were important systematic differences. Estimates from the EC method were generally lowest, followed by those from the inertial-dissipation method. The LP method produced the highest values and the greatest scatter. We show that these results are consistent with boundary-layer theory when sediment-induced stratification is present. The EC method provides the most fundamental estimate of kinematic stress near the bottom, and stratification causes the LP method to overestimate bottom stress. These results remind us that the methods are not equivalent and that comparison among sites and with models should be made carefully. ?? 2006 Elsevier Ltd.

Not all alien species responded the same, as the alien forb Erodium cicutarium and the alien grass Schismus spp. increased with proximity to watering sites, and the alien annual grass Bromus madritensis ssp. rubens decreased. Perennial plant cover and species richness also declined with proximity to watering sites, as did the structural diversity of perennial plant cover classes.
