Evapotranspiration (ET) by riparian vegetation is an important, but poorly quantified, term in river water budgets. Native tree restoration plots will potentially increase ET. We used sap flow sensors and satellite imagery to estimate ET in a 8 ha, cottonwood (Populus fremontii) restoration plot on the Lower Colorado River. Biometric methods were used to scale leaf area to whole trees and stands of trees. This technique was used to validate our estimates of ET obtained by scaling from branch level to stand (or plot) level measurements of ET. Cottonwood trees used 6-10 mm day-1 of water during the peak of the growing season as determined by sap flow sensors, and annual rates scaled by time-series MODIS satellite imagery were approximately 1.2 m year-1. Although irrigation was not quantified, the field had been flood irrigated at 2 week intervals during the 3 years prior to the study, receiving approximately 2 m year-1 of water. A frequency-domain electromagnetic induction survey of soil moisture content showed that the field was saturated (26-28% gravimetric water content) at the 90-150 cm soil depth under the field. Trees were apparently rooted into the saturated soil, and considerable saving of water could potentially be achieved by modifying the irrigation regime to take into account that cottonwoods are phreatophytes. The study showed that cottonwood ET can be monitored by remote sensing methods calibrated with ground measurements with an accuracy or uncertainty of 20-30% in western riparian corridors. ?? 2007 Elsevier B.V.

This wetland index can be calculated with species data, or with community type data as performed here. Classified riparian community types were used to describe vegetation at 14 livestock exclosures and adjacent grazed areas. Community type wetland index values were generated and used to calculate site wetland index values. It was hypothesized that removal of livestock would result in higher wetland index values because of release from herbivory and decreased physical disturbance of vegetation, streambanks, and soil. The wetland index for exclosures was about 12% higher than grazed sites; differences were statistically significant (p &lt; 0.01) based on paired t-tests. The increase in hydric vegetation after livestock exclusion may have contributed to the greater bank stability (p = 0.002) and smaller width-to-depth ratio (p = 0.005) in exclosures. Challenges were encountered in using community types to describe and compare site vegetation, which could be avoided with species data collection. The wetland index can be a tool to monitor sites over time, compare sites with similar environments, or compare sites for which environmental differences can be accounted. </p>","language":"English","publisher":"American Water Resources Association","doi":"10.1111/j.1752-1688.2007.00058.x","issn":"1093474X","usgsCitation":"Coles-Ritchie, M.C., Roberts, D., Kershner, J.L., and Henderson, R., 2007, Use of a wetland index to evaluate changes in riparian vegetation after livestock exclusion: Journal of the American Water Resources Association, v. 43, no. 3, p. 731-743, https://doi.org/10.1111/j.1752-1688.2007.00058.x.","productDescription":"13 p.","startPage":"731","endPage":"743","numberOfPages":"13","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":481,"text":"Northern Rocky Mountain Science Center","active":true,"usgs":true}],"links":[{"id":477244,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1111/j.1752-1688.2007.00058.x","text":"Publisher Index Page"},{"id":238912,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":211597,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1752-1688.2007.00058.x"}],"volume":"43","issue":"3","noUsgsAuthors":false,"publicationDate":"2007-05-14","publicationStatus":"PW","scienceBaseUri":"505bbea3e4b08c986b3296d1","contributors":{"authors":[{"text":"Coles-Ritchie, M.

A comprehensive genotyping of 237 IHNV isolates from hatchery and wild salmonids in California revealed 25 different sequence types (a to y) all in the L genogroup; specifically, the genogroup contained 14 sequence types that were unique to individual isolates as well as 11 sequence types representing 2 or more identical isolates. The most evident trend was the phylogenetic and geographical division of the L genogroup into 2 distinct subgroups designated as LI and LII. Isolates within Subgroup LI were primarily found within waterways linked to southern Oregon and northern California coastal rivers. Isolates in Subgroup LII were concentrated within inland valley watersheds that included the Sacramento River, San Joaquin River, and their tributaries. The temporal and spatial patterns of virus occurrence suggested that infections among adult Chinook salmon in the hatchery or that spawn in the river are a major source of virus potentially infecting other migrating or resident salmonids in California. Serum neutralization results of the California isolates of IHNV corroborated a temporal trend of sequence divergence; specifically, 2 progressive shifts in which more recent virus isolates represent new serotypes. A comparison of the estimates of divergence rates for Subgroup LI (1 ?? ICT5 mutations per nucleotide site per year) indicated stasis similar to that observed in the U genogroup, while the Subgroup LII rate (1 ?? 10 3 mutations per nucleotide site per year) suggested a more active evolution similar to that of the M genogroup. ??

In this study, results of high-resolution water table monitoring under three common riparian land covers (forest, cool season grass, corn) were analysed to gain a better understanding of the relation of vegetation cover to water table depth. Three riparian wells located at the Neal Smith National Wildlife Refuge in Jasper County, Iowa, were instrumented with data loggers to record hourly water table behaviour from July to December 2004. Water table depth under the forest showed a diurnal pattern of rising and falling water levels, whereas the grass and corn exhibited a stepped pattern of greater drawdown during the day and less drainage at night. Clear daytime and night-time water table signals were related to daily plant water demands and lateral groundwater flow. Using two estimates of specific yield, hourly and daily ET rates were estimated to be higher under the forest cover than the grass and corn, with peak ET rates in July ranging from 5.02 to 6.32 mm day-1 for forest and from 1.81 to 4.13 mm day-1 for corn and grass. Following plant senescence in October, water table declines were associated with lateral flow to Walnut Creek. The results from this study suggest that consideration should be given to monitoring water table behaviour more frequently to capture daily and seasonal patterns related to riparian vegetation type.

This interpretation is supported by earlier research that showed progressively greater ratios in the marine sediment fraction of Cr:Ni&gt;V:Ni⪢Mo:Ni, relative to their ratios in seawater; for which marine Cr, V, and Mo can have a dominantly O<sub>2</sub>–depleted bottom-water source and Ni a photic-zone, largely algal, source.

Regions of altered land cover include large portions of Europe, India, eastern China, and the eastern United States. Smaller areas of change are present in various tropical regions. This study focuses on the impacts of biophysical changes associated with the land cover change (albedo, root and stomatal properties, roughness length), which is almost exclusively a conversion from forest to grassland in the model; the effects of irrigation or other water management practices and the effects of atmospheric carbon dioxide changes associated with land cover conversion are not included in these experiments. The model suggests that observed land cover changes have little or no impact on globally averaged climatic variables (e.g., 2-m air temperature is 0.008 K warmer in a simulation with 1990 land cover compared to a simulation with potential natural vegetation cover). Differences in the annual mean climatic fields analyzed did not exhibit global field significance. Within some of the regions of land cover change, however, there are relatively large changes of many surface climatic variables. These changes are highly significant locally in the annual mean and in most months of the year in eastern Europe and northern India. They can be explained mainly as direct and indirect consequences of model-prescribed increases in surface albedo, decreases in rooting depth, and changes of stomatal control that accompany deforestation. ?? 2007 American Meteorological Society.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Climate","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1175/JCLI4185.1","issn":"08948755","usgsCitation":"Findell, K., Shevliakova, E., Milly, P., and Stouffer, R., 2007, Modeled impact of anthropogenic land cover change on climate: Journal of Climate, v. 20, no. 14, p. 3621-3634, https://doi.org/10.1175/JCLI4185.1.","startPage":"3621","endPage":"3634","numberOfPages":"14","costCenters":[],"links":[{"id":477007,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1175/jcli4185.1","text":"Publisher Index Page"},{"id":238874,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":211567,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1175/JCLI4185.1"}],"volume":"20","issue":"14","noUsgsAuthors":false,"publicationDate":"2007-07-15","publicationStatus":"PW","scienceBaseUri":"505a5bbde4b0c8380cd6f78e","contributors":{"authors":[{"text":"Findell, K.L.","contributorId":20137,"corporation":false,"usgs":true,"family":"Findell","given":"K.L.","affiliations":[],"preferred":false,"id":429922,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Shevliakova, E.","contributorId":27238,"corporation":false,"usgs":true,"family":"Shevliakova","given":"E.","affiliations":[],"preferred":false,"id":429924,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Milly, P.

A three‐dimensional, multiphase flow model of two horizontal collector wells along the Russian River near Forestville, California, was developed to investigate the impact of varying the ratio of the aquifer to streambed permeability on (1) the formation of an unsaturated region beneath the stream, (2) the pumping capacity, (3) stream water fluxes through the streambed, and (4) stream water traveltimes to the collector wells. The aquifer to streambed permeability ratio at which the unsaturated region was initially observed ranged from 10 to 100. The size of the unsaturated region beneath the streambed increased as the aquifer to streambed permeability ratio increased. The simulations also indicated that for a particular aquifer permeability, decreasing the streambed permeability by only a factor of 2–3 from the permeability where desaturation initially occurred resulted in reducing the pumping capacity. In some cases, the stream water fluxes increased as the streambed permeability decreased. However, the stream water residence times increased and the fraction of stream water that reached that the wells decreased as the streambed permeability decreased, indicating that a higher streambed flux does not necessarily correlate to greater recharge of stream water around the wells.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/2006WR005389","usgsCitation":"Su, G.W., Jasperse, J., Seymour, D., Constantz, J., and Zhou, Q., 2007, Analysis of pumping‐induced unsaturated regions beneath a perennial river: Water Resources Research, v. 43, no. 8, W08421, 14 p., https://doi.org/10.1029/2006WR005389.","productDescription":"W08421, 14 p.","costCenters":[],"links":[{"id":477077,"rank":2,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1029/2006wr005389","text":"Publisher Index Page"},{"id":238873,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"43","issue":"8","noUsgsAuthors":false,"publicationDate":"2007-08-22","publicationStatus":"PW","scienceBaseUri":"5059eb29e4b0c8380cd48c6d","contributors":{"authors":[{"text":"Su, Grace W.","contributorId":145734,"corporation":false,"usgs":false,"family":"Su","given":"Grace","email":"","middleInitial":"W.","affiliations":[{"id":595,"text":"U.S. Geological Survey","active":false,"usgs":true}],"preferred":false,"id":429917,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Jasperse, James","contributorId":64857,"corporation":false,"usgs":false,"family":"Jasperse","given":"James","email":"","affiliations":[],"preferred":false,"id":429920,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Seymour, Donald","contributorId":175253,"corporation":false,"usgs":false,"family":"Seymour","given":"Donald","email":"","affiliations":[{"id":17863,"text":"Sonoma County Water Agency","active":true,"usgs":false}],"preferred":false,"id":429919,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Constantz, James E. 0000-0002-4062-2096 jconstan@usgs.gov","orcid":"https://orcid.org/0000-0002-4062-2096","contributorId":1962,"corporation":false,"usgs":true,"family":"Constantz","given":"James E.","email":"jconstan@usgs.gov","affiliations":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"preferred":true,"id":429918,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Zhou, Quanlin","contributorId":178881,"corporation":false,"usgs":false,"family":"Zhou","given":"Quanlin","email":"","affiliations":[],"preferred":false,"id":429921,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Periphyton samples were collected using trace element clean techniques and NAWQA sampling protocols in spring and fall from targeted habitats (streambed surface-sediment, cobble, or woody snags) at each river site. A positive correlation was observed between concentrations of THg and MeHg in periphyton (r2 = 0.88, in log-log space). Mean MeHg and THg concentrations in surface-sediment periphyton were significantly higher (1,333 ng/m2 for MeHg and 53,980 ng/m2 for THg) than cobble (64 ng/m2 for MeHg and 1,192 ng/m2 for THg) or woody snag (71 ng/m2 for MeHg and 1,089 ng/m2 for THg) periphyton. Concentrations of THg in surface-sediment periphyton had a strong positive correlation with concentrations of THg in sediment (dry weight). The ratio of MeHg:THg in surface-sediment periphyton increased with the ratio of MeHg:THg in sediment.

The SYBR based assay using Boyle primers (SYBR/Boyle assay) and the Taqman based assay using Wood primers performed similarly with samples generated in the laboratory (Bd spiked filters), but the SYBR/Boyle assay detected Bd DNA in more field samples. We detected Bd DNA in water from 3 of 4 sites tested, including one pond historically negative for chytridiomycosis. Zoospore equivalents in sampled water ranged from 19 to 454 l-1 (nominal detection limit is 10 DNA copies, or about 0.06 zoospore). We did not detect DNA of Bd from sediments collected at any sites.

This transgression extended farther westward across the Virginia Piedmont than any other transgression that has been documented. Extensive fluvial deposits that may be associated with this transgression covered earlier stream patterns in the eastern Piedmont and buried them beneath a thin (probably less than 100 foot-thick) veneer of sand and gravel. During the subsequent regression, a linear down-slope stream-drainage pattern developed. Although it has been somewhat modified by later stream captures, it still is easily recognizable. This interval of marine inundation and deposition explains why modern stream patterns in the eastern Piedmont of Virginia strongly resemble the stream patterns in the Coastal Plain and differ from the structurally adjusted trellis stream patterns typical of the western Piedmont, Blue Ridge, and Valley and Ridge regions. Uplift of the modern Southern Appalachian Mountains began at the time of this transgression and was largely completed by the late Pliocene.","language":"English","issn":"00262803","usgsCitation":"Weems, R.E., and Edwards, L.E., 2007, Post-middle Miocene origin of modern landforms in the eastern Piedmont of Virginia: Stratigraphy, v. 4, no. 1, p. 35-48.","productDescription":"14 p.","startPage":"35","endPage":"48","numberOfPages":"14","costCenters":[{"id":243,"text":"Eastern Geology and Paleoclimate Science Center","active":true,"usgs":true},{"id":40020,"text":"Florence Bascom Geoscience Center","active":true,"usgs":true}],"links":[{"id":238779,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Virginia ","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -83.4521484375,\n              36.66841891894786\n            ],\n            [\n              -75.849609375,\n              36.59788913307022\n            ],\n            [\n              -76.0693359375,\n              37.54457732085582\n            ],\n            [\n              -76.6845703125,\n              38.85682013474361\n            ],\n            [\n              -77.87109375,\n              39.33429742980725\n            ],\n            [\n              -78.2666015625,\n              39.26628442213066\n            ],\n            [\n              -79.365234375,\n              38.54816542304656\n            ],\n            [\n              -80.2001953125,\n              37.43997405227057\n            ],\n            [\n              -81.5625,\n              37.16031654673677\n            ],\n            [\n              -81.9580078125,\n              37.47485808497102\n            ],\n            [\n              -83.4521484375,\n              36.66841891894786\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"4","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a7e6ae4b0c8380cd7a522","contributors":{"authors":[{"text":"Weems, Robert E. 0000-0002-1907-7804 rweems@usgs.gov","orcid":"https://orcid.org/0000-0002-1907-7804","contributorId":2663,"corporation":false,"usgs":true,"family":"Weems","given":"Robert","email":"rweems@usgs.gov","middleInitial":"E.","affiliations":[{"id":243,"text":"Eastern Geology and Paleoclimate Science Center","active":true,"usgs":true},{"id":40020,"text":"Florence Bascom Geoscience Center","active":true,"usgs":true}],"preferred":true,"id":429897,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Edwards, Lucy E. 0000-0003-4075-3317 leedward@usgs.gov","orcid":"https://orcid.org/0000-0003-4075-3317","contributorId":2647,"corporation":false,"usgs":true,"family":"Edwards","given":"Lucy","email":"leedward@usgs.gov","middleInitial":"E.","affiliations":[{"id":40020,"text":"Florence Bascom Geoscience Center","active":true,"usgs":true},{"id":243,"text":"Eastern Geology and Paleoclimate Science Center","active":true,"usgs":true}],"preferred":true,"id":429896,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Declines in lake pH can lead to reductions in food availability and quality, or result in the altered availability of toxic metals, such as mercury. A recent laboratory study conducted by the U.S. Geological Survey and the Wisconsin Department of Natural Resources indicated that Common Loon (Gavia immer) chicks hatched from eggs collected on acidic lakes in northern Wisconsin may be less responsive to stimuli and exhibit reduced growth compared to chicks from neutral-pH lakes. Here we report on the relation between Common Loon egg characteristics (eggshell thickness and egg volume) and lake pH, as well as eggshell methylmercury content. Eggs (N = 84) and lake pH measurements were obtained from a four county region of northern Wisconsin. Egg-shells were 3-4% thinner on lakes with pH ??? 6.3 than on neutral-pH lakes and this relation was linear across the pH range investigated (P < 0.05). Egg volume also tended to be larger in eggs from neutral-pH lakes. Eggshell methylmercury content however was not significantly related to shell thickness (P > 0.05, n.s.) or lake pH. Results suggest that low lake pH may be associated with thinner eggshells and reduced egg volume in Common Loons. We speculate on the mechanisms that may lead to this phenomeno.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Waterbirds","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1675/1524-4695(2007)030[0367:CLGIET]2.0.CO;2","issn":"15244695","usgsCitation":"Pollentier, C., Kenow, K., and Meyer, M., 2007, Common Loon (Gavia immer) eggshell thickness and egg volume vary with acidity of nest lake in northern Wisconsin: Waterbirds, v. 30, no. 3, p. 367-374, https://doi.org/10.1675/1524-4695(2007)030[0367:CLGIET]2.0.CO;2.","startPage":"367","endPage":"374","numberOfPages":"8","costCenters":[],"links":[{"id":238745,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":211454,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1675/1524-4695(2007)030[0367:CLGIET]2.0.CO;2"}],"volume":"30","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f7fae4b0c8380cd4cdf3","contributors":{"authors":[{"text":"Pollentier, C.D.","contributorId":78538,"corporation":false,"usgs":true,"family":"Pollentier","given":"C.D.","email":"","affiliations":[],"preferred":false,"id":429891,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kenow, K.P.","contributorId":18302,"corporation":false,"usgs":true,"family":"Kenow","given":"K.P.","affiliations":[],"preferred":false,"id":429889,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Meyer, M.W.","contributorId":38094,"corporation":false,"usgs":true,"family":"Meyer","given":"M.W.","email":"","affiliations":[],"preferred":false,"id":429890,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Farther north in New Mexico these five ammonite zones occur over a stratigraphic interval more than an order of magnitude thicker. The basal part of this marine sequence was deposited in Seboyeta Bay, an elongate east-west embayment into New Mexico that marked the initial transgression of the western shoreline of the Late Cretaceous seaway into New Mexico. </p><p>The primary mechanism for condensing this section was nearshore, submarine erosion, although nondeposition played a minor role. The ammonite fossils from each zone are generally fragments of internal molds that are corroded on one side, indicating submarine burial, erosion of the prefossilized steinkern, and corrosion on the sea floor. In addition, the base of the condensed succession is marked by a thin bed that contains abundant, white-weathering, spherical to cylindrical phosphate nodules, many of which contain a cylindrical axial cavity of unknown origin. </p><p>The nodules lie on the bedding surface of the highly burrowed, ridge-forming sandstone near the top of the Dakota and occur in the overlying breccia. The breccia consists of rip-up clasts of sandstone and eroded internal molds of the ammonite Conlinoceras tarrantense, the zonal index for the basal middle Cenomanian. The nodules below the breccia imply a time of erosion followed by nondeposition or sediment bypass during which the phosphatization occurred. The breccia implies a time of submarine erosion, probably storm-related. </p><p>Remarkably, this condensed succession and the basal part of the overlying Mancos Shale tongue contain one of the most complete middle Cenomanian ammonite sequences in the U.S. Western Interior. Five of the six ammonite zones that characterize the middle Cenomanian of the Western Interior are found on Sevilleta National Wildlife Refuge. Only representatives of the second oldest zone are missing, although stratigraphically there is room for this zone. Fossils from each zone occur in stratigraphically separated beds; no zone overlaps with or is superimposed on another.</p><p>Maps of the western shoreline of the seaway at the beginning and end of the time represented by the condensed succession show the progression of the Late Cretaceous seaway from embayment to ocean covering most of New Mexico. These maps, combined with the resolving power of the middle Cenomanian biostratigraphic framework, indicate that the southern shoreline of Seboyeta Bay, which was only a few miles south of Sevilleta National Wildlife Refuge, was virtually stationary for most of this time. This ensured that the refuge was under shallow, well-oxygenated, marine waters for much of middle Cenomanian time. It also ensured that deposited sediments would be subjected periodically to erosion by nearshore waves and currents. </p><p>This report marks the first recorded occurrence in New Mexico of the following ammonite species: <i>Acanthoceras muldoonense</i> (zonal index), <i>A. bellense</i> (zonal index), <i>Turrilites (Euturrilites) scheuchzerianus</i>, <i>Cunningtoniceras</i> cf. <i>C. cunningtoni</i>, and <i>Paraconlinoceras leonense</i>.

This investigation systematically examines the role of interannual to multidecadal climate variability on groundwater levels, deep infiltration (3–23 m) events, and downward displacement (&gt;1 m) of chloride and nitrate reservoirs in thick (15–50 m) vadose zones across the regionally extensive High Plains aquifer. Such vadose zone responses are unexpected across much of the aquifer given a priori that unsaturated total-potential profiles indicate upward water movement from the water table toward the root zone, mean annual potential evapotranspiration exceeds mean annual precipitation, and millennia-scale evapoconcentration results in substantial vadose zone chloride and nitrate reservoirs. Using singular spectrum analysis (SSA) to reconstruct precipitation and groundwater level time-series components, variability was identified in all time series as partially coincident with known climate cycles, such as the Pacific Decadal Oscillation (PDO) (10–25 yr) and the El Niño/Southern Oscillation (ENSO) (2–6 yr). Using these lag-correlated hydrologic time series, a new method is demonstrated to estimate climate-varying unsaturated water flux.

Using shallow water ponds rehabilitated with a technique called marsh terracing, we examined the quality of nekton habitat created, using and comparing several metrics including nekton density and diversity, functional group composition, and weight-length relationships as indirect measures of habitat quality. We examined three paired terraced and unterraced marsh ponds in southwest Louisiana. Nekton, submerged aquatic vegetation (SAV), and soil and water quality variables were sampled bimonthly from April 2004 through April 2005 at four subtidal habitat types: terraced nearshore, terraced open water, unterraced nearshore, and unterraced open water. Results indicate that terraced ponds had increased the habitat value of degrading unterraced ponds over open water areas for estuarine nekton; nekton density and richness were similar between terraced and unterraced nearshore habitat types, but greater at all nearshore as compared to open water sites. Analysis of the distribution of nekton functional groups and weight:length ratios indicates the terraced and unterraced pond habitats were not functioning similarly: distribution of nekton functional groups differed significantly between habitat types with greater percentages of benthic-oriented species at unterraced open water habitats and higher percentage of open water species in terraced ponds as compared to unterraced ponds, and two of the six numerically dominant fish species had greater weight-length relationships in unterraced ponds as compared to terraced ponds. This lack of functional equivalency may be attributed to environmental differences between terraced and unterraced ponds such as water depth or SAV biomass, or the relatively young age of the terraces studied, which may not have allowed for the development of some critical habitat variables, such as soil organic matter that was found to be significantly lower in terraced versus unterraced ponds (p &lt; 0.05). To properly assess the ecological equivalency of restored or rehabilitated sites for nekton requires that we move beyond measures of nekton density, biomass, and diversity and incorporate measures of functional equivalency, including habitat measures.&nbsp;</p>","language":"English","publisher":"SpringerLink","doi":"10.1007/BF03036518","usgsCitation":"La Peyre, M., Gossman, B., and Nyman, J., 2007, Assessing functional equivalency of nekton habitat in enhanced habitats: Comparison of terraced and unterraced marsh ponds: Estuaries and Coasts, v. 30, no. 3, p. 526-536, https://doi.org/10.1007/BF03036518.","productDescription":"11 p.","startPage":"526","endPage":"536","costCenters":[{"id":368,"text":"Louisiana Cooperative Fish and Wildlife Research Unit","active":false,"usgs":true}],"links":[{"id":238940,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Louisiana","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -93.80126953124999,\n              29.592565403314058\n            ],\n            [\n              -92.04345703125,\n              29.592565403314058\n            ],\n            [\n              -92.04345703125,\n              30.958768570779846\n            ],\n            [\n              -93.66943359374999,\n              30.883369321692268\n            ],\n            [\n              -93.80126953124999,\n              29.592565403314058\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"30","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059edd5e4b0c8380cd49a33","contributors":{"authors":[{"text":"La Peyre, M.K. 0000-0001-9936-2252","orcid":"https://orcid.org/0000-0001-9936-2252","contributorId":102239,"corporation":false,"usgs":true,"family":"La Peyre","given":"M.K.","affiliations":[],"preferred":false,"id":429768,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Gossman, B.","contributorId":47163,"corporation":false,"usgs":true,"family":"Gossman","given":"B.","email":"","affiliations":[],"preferred":false,"id":429766,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Nyman, J.A.","contributorId":56835,"corporation":false,"usgs":true,"family":"Nyman","given":"J.A.","email":"","affiliations":[],"preferred":false,"id":429767,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

This makes effective management of groundwater resources difficult by masking how much water has been derived from storage and, in some cases, the total amount of water that has been extracted from an aquifer system. Analyzing confining layer storage is viewed as troublesome because of the additional computational burden and because the hydraulic properties of confining layers are poorly known. In this paper we propose a simplified method for computing estimates of confining layer depletion, as well as procedures for approximating confining layer hydraulic conductivity (</span><i>K</i><span>) and specific storage (</span><i>S</i><sub><i>s</i></sub><span>) using geologic information. The latter makes the technique useful in developing countries and other settings where minimal data are available or when scoping calculations are needed. As such, our approach may be helpful for estimating the global transfer of groundwater to surface water. A test of the method on a synthetic system suggests that the computational errors will generally be small. Larger errors will probably result from inaccuracy in confining layer property estimates, but these may be no greater than errors in more sophisticated analyses. The technique is demonstrated by application to two aquifer systems: the Dakota artesian aquifer system in South Dakota and the coastal plain aquifer system in Virginia. In both cases, depletion from confining layers was substantially larger than depletion from the aquifers.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/2006WR005597","usgsCitation":"Konikow, L.F., and Neuzil, C.E., 2007, A method to estimate groundwater depletion from confining layers: Water Resources Research, v. 43, no. 7, W07417; 15 p., https://doi.org/10.1029/2006WR005597.","productDescription":"W07417; 15 p.","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":477219,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1029/2006wr005597","text":"Publisher Index Page"},{"id":238609,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","volume":"43","issue":"7","noUsgsAuthors":false,"publicationDate":"2007-07-13","publicationStatus":"PW","scienceBaseUri":"5059e460e4b0c8380cd465ff","contributors":{"authors":[{"text":"Konikow, Leonard F. 0000-0002-0940-3856 lkonikow@usgs.gov","orcid":"https://orcid.org/0000-0002-0940-3856","contributorId":158,"corporation":false,"usgs":true,"family":"Konikow","given":"Leonard","email":"lkonikow@usgs.gov","middleInitial":"F.","affiliations":[{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true}],"preferred":true,"id":429688,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Neuzil, Christopher E. 0000-0003-2022-4055 ceneuzil@usgs.gov","orcid":"https://orcid.org/0000-0003-2022-4055","contributorId":2322,"corporation":false,"usgs":true,"family":"Neuzil","given":"Christopher","email":"ceneuzil@usgs.gov","middleInitial":"E.","affiliations":[{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true}],"preferred":true,"id":429689,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Radiocarbon dating is problematic for dambos due to (i) oxidation of organic materials during dry seasons; and (ii) the potential for contemporary biological contamination of near-surface sediments. However, for luminescence dating the equatorial site and semi-arid climate facilitate grain bleaching, while the gentle terrain ensures shallow water columns, low turbidity, and relatively long surface exposures for transported grains prior to deposition and burial. For this study, we focused on dating sandy strata (indicative of high-energy fluvial events) at various positions and depths within a second-order dambo in central Uganda. Blue-light quartz optically stimulated luminescences (OSL) ages were compared with infrared stimulated luminescence (IRSL) and thermoluminescence (TL) ages from finer grains in the same sample. A total of 8 samples were dated, with 6 intervals obtained at ???35, 33, 16, 10.4, 8.4, and 5.9 ka. In general, luminescence ages were stratigraphically, geomorphically and ordinally consistent and most blue-light OSL ages could be correlated with well-dated climatic events registered either in Greenland ice cores or Lake Victoria sediments. Based upon OSL age correlations, we theorize that extreme fluvial dambo events occur primarily during relatively wet periods, often preceding humid-to-arid transitions. The optical ages reported in this study provide the first detailed chronology of dambo sedimentation, and we anticipate that further dambo work could provide a wealth of information on the paleohydrology of Central and Southern Africa. ?? 2006 Elsevier Ltd.

We support this scenario but a fundamental question remains: What caused the repeated marine invasions? We offer an hypothesis for the repeated marine invasions of the Black Sea based on: (1) the overall similarity of sea-level curves from both tectonically quiescent and active margins of the Black Sea and their similarity to a sequence stratigraphic record from the US mid-Atlantic coast. The similarity of the records from two widely-separated regions suggests their common response to documented Holocene climate ocean-atmosphere reorganizations (coolings); (2) the fact that in the modern Black Sea, freshwater runoff from surrounding rivers dominates over evaporation, so that excess runoff might have temporarily raised Black Sea level (although the Black Sea would have remained brackish). Following the initial invasion of the Black Sea by marine Mediterranean waters (through the Marmara Sea) in the early Holocene, repeated marine incursions were modulated, or perhaps even caused, by freshwater discharge to the Black Sea. Climatic amelioration (warming) following each documented ocean-atmosphere reorganization during the Holocene likely shifted precipitation patterns in the surrounding region and caused mountain glaciers to retreat, increasing freshwater runoff above modern values and temporarily contributing to an increase of Black Sea level. Freshwater-to-brackish water discharges into the Black Sea initially slowed marine inflow but upon mixing of runoff with more marine waters beneath them and their eventual exit through the Bosphorus, marine inflow increased again, accounting for the repeated marine invasions. The magnitude of the hydrologic and sea-level fluctuations became increasingly attenuated through the Holocene, as reflected by Black Sea level curves. ?? 2006 Elsevier Ltd and INQUA.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Quaternary International","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.quaint.2006.11.003","issn":"10406182","usgsCitation":"Martin, R., Leorri, E., and McLaughlin, P., 2007, Holocene sea level and climate change in the Black Sea: Multiple marine incursions related to freshwater discharge events: Quaternary International, v. 167-168, p. 61-72, https://doi.org/10.1016/j.quaint.2006.11.003.","startPage":"61","endPage":"72","numberOfPages":"12","costCenters":[],"links":[{"id":211274,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.quaint.2006.11.003"},{"id":238538,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"167-168","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a31f0e4b0c8380cd5e387","contributors":{"authors":[{"text":"Martin, R.E.","contributorId":7654,"corporation":false,"usgs":true,"family":"Martin","given":"R.E.","email":"","affiliations":[],"preferred":false,"id":429671,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Leorri, E.","contributorId":46283,"corporation":false,"usgs":true,"family":"Leorri","given":"E.","affiliations":[],"preferred":false,"id":429673,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"McLaughlin, P.P.","contributorId":45865,"corporation":false,"usgs":true,"family":"McLaughlin","given":"P.P.","affiliations":[],"preferred":false,"id":429672,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Seven deep-water coral sites (384-756 m), located between Cape Lookout, NC, and Cape Canaveral, FL, were sampled in June 2004 using a manned submersible. The presence of regenerative tissue was evaluated by visual inspection of each individual ophiuroid, and the proportion of regenerating arms per individual was examined relative to size of individual, geographic location, and depth of collection. Ophiacantha bidentata, the dominant brittle star collected, commonly displayed signs of sublethal injury with over 60% of individuals displaying some evidence of regeneration. These levels of regeneration rival those reported for shallow-water ophiuroids. Larger individuals (>6.5 mm disc size) had a higher incidence of regeneration than smaller individuals. Size of individual and percent of regeneration were negatively correlated with depth. Although O. bidentata was significantly less abundant in southern versus northern sites, ophiuroid abundance did not appear to be influenced by amount or density of coral substratum. Presence of dense aggregations of O. bidentata indicates that they are an important component of the invertebrate assemblage associated with deep-water coral habitat especially in the northern part of the study area. Assuming that observed frequencies of injury and subsequent regeneration represent predation events then dense ophiuroid aggregations in deep-water coral habitats represent an important renewable trophic resource within these communities. ?? 2007 Springer-Verlag.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Marine Biology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1007/s00227-007-0690-4","issn":"00253162","usgsCitation":"Allen, B.R., Nizinski, M., Ross, S.W., and Sulak, K., 2007, Frequency of sublethal injury in a deepwater ophiuroid, Ophiacantha bidentata, an important component of western Atlantic Lophelia reef communities: Marine Biology, v. 152, no. 2, p. 307-314, https://doi.org/10.1007/s00227-007-0690-4.","startPage":"307","endPage":"314","numberOfPages":"8","costCenters":[],"links":[{"id":211643,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s00227-007-0690-4"},{"id":238970,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"152","issue":"2","noUsgsAuthors":false,"publicationDate":"2007-04-24","publicationStatus":"PW","scienceBaseUri":"505a13d2e4b0c8380cd547bc","contributors":{"authors":[{"text":"Allen, Brooks R.","contributorId":87361,"corporation":false,"usgs":true,"family":"Allen","given":"Brooks","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":429654,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Nizinski, M.S.","contributorId":94495,"corporation":false,"usgs":true,"family":"Nizinski","given":"M.S.","affiliations":[],"preferred":false,"id":429655,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Ross, Steve W.","contributorId":72543,"corporation":false,"usgs":false,"family":"Ross","given":"Steve","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":429652,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Sulak, K.

We determined the nitrogen isotopic signatures (δ<sup>15</sup>N) of different nitrate sources to Hanalei Bay along with the isotopic signature recorded by 11 species of macroalgal collected in the Bay. The macroalgae integrate the isotopic signatures of the nitrate sources over time, thus these data along with the nitrate to dissolved inorganic phosphate molar ratios (N:P) of the macroalgae were used to determine the major nitrate source to the bay ecosystem and which of the macro-nutrients is limiting algae growth, respectively. Relatively low δ<sup>15</sup>N values (average −0.5‰) were observed in all algae collected throughout the Bay; implicating fertilizer, rather than domestic sewage, as an important external source of nitrogen to the coastal water around Hanalei. The N:P ratio in the algae compared to the ratio in the Bay waters imply that the Hanalei Bay coastal ecosystem is nitrogen limited and thus, increased nitrogen input may potentially impact this coastal ecosystem and specifically the coral reefs in the Bay. Identifying the major source of nutrient loading to the Bay is important for risk assessment and potential remediation plans.</p></div></div></div></div></div>","language":"English","publisher":"American Chemical Society","doi":"10.1021/es0700449","issn":"0013936X","usgsCitation":"Derse, E., Knee, K., Wankel, S.D., Kendall, C., Berg, C.J., and Paytan, A., 2007, Identifying sources of nitrogen to Hanalei Bay, Kauai, utilizing the nitrogen isotope signature of macroalgae: Environmental Science & Technology, v. 41, no. 15, p. 5217-5223, https://doi.org/10.1021/es0700449.","productDescription":"7 p.","startPage":"5217","endPage":"5223","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":238939,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Hawaii","otherGeospatial":"Kauai Island, Hanalei Bay","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -159.53350067138672,\n              22.19916683397288\n            ],\n            [\n              -159.48526382446286,\n              22.19916683397288\n            ],\n            [\n              -159.48526382446286,\n              22.234446448737298\n            ],\n            [\n              -159.53350067138672,\n              22.234446448737298\n            ],\n            [\n              -159.53350067138672,\n              22.19916683397288\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"41","issue":"15","noUsgsAuthors":false,"publicationDate":"2007-06-19","publicationStatus":"PW","scienceBaseUri":"505a3856e4b0c8380cd6152b","contributors":{"authors":[{"text":"Derse, E.","contributorId":55637,"corporation":false,"usgs":true,"family":"Derse","given":"E.","email":"","affiliations":[],"preferred":false,"id":429648,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Knee, K.L.","contributorId":13811,"corporation":false,"usgs":true,"family":"Knee","given":"K.L.","affiliations":[],"preferred":false,"id":429646,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Wankel, Scott D.","contributorId":98076,"corporation":false,"usgs":true,"family":"Wankel","given":"Scott","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":429650,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Kendall, Carol 0000-0002-0247-3405 ckendall@usgs.gov","orcid":"https://orcid.org/0000-0002-0247-3405","contributorId":1462,"corporation":false,"usgs":true,"family":"Kendall","given":"Carol","email":"ckendall@usgs.gov","affiliations":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"preferred":true,"id":429647,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Berg, Carl J.

Similarly, among 89-day-1-year-old and 1+year old post-metamorphosed juveniles, cumulative mortality was significantly greater in VHSV-challenged groups than in respective control groups. Larval exposure to VHSV conferred partial protection to the survivors after their metamorphosis to juveniles as shown by significantly less cumulative mortalities among juvenile groups that survived a VHS epidemic as larvae than among groups that were previously nai??ve to VHSV. Magnitude of the protection, measured as relative per cent survival, was a direct function of larval age at first exposure and was probably a reflection of gradual developmental onset of immunocompetence.

Crucian carp and SPMDs were deployed side by side for 32 d. The first-order uptake rate constants of individual PAHs and OCPs for the two matrices were calculated and compared to relate the amounts of chemicals accumulated by the matrices to dissolved water concentrations. On a wet-weight basis, total concentrations of PAHs and OCPs in crucian carp fillets averaged 49.5 and 13.6 ng/g, respectively, after the 32-d exposure, whereas concentrations in whole SPMDs averaged 716.9 and 62.3 ng/g, respectively. The uptake rate constants of PAHs and OCPs by SPMDs averaged seven- and fivefold higher, respectively, than those for crucian carp; however, the patterns of uptake rate constants derived from test chemical concentrations in the crucian carp and SPMDs were similar. Although equilibrium was not reached for some PAHs and OCPs during the 32-d exposure period, a reasonably good correlation between the concentration factors (CFs) and octanol/water partition coefficient (K ow) values of PAHs and OCPs in SPMDs (r = 0.86, p < 0.001) was observed when potential sorption to dissolved organic carbon was taken into account. Similar efforts to correlate the CFs and Kow values of PAHs and OCPs in crucian carp (r = 0.75, p < 0.001) were less successful, likely because of PAH metabolism by finfish. Overall, the present results suggest that SPMDs may serve as a surrogate for contaminant monitoring with fish in freshwater lake environments. ?? 2007 SETAC.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Toxicology and Chemistry","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1897/06-454R1.1","issn":"07307268","usgsCitation":"Ke, R., Xu, Y., Huang, S., Wang, Z., and Huckins, J., 2007, Comparison of the uptake of polycyclic aromatic hydrocarbons and organochlorine pesticides by semipermeable membrane devices and caged fish (Carassius carassius) in Taihu Lake, China: Environmental Toxicology and Chemistry, v. 26, no. 6, p. 1258-1264, https://doi.org/10.1897/06-454R1.1.","startPage":"1258","endPage":"1264","numberOfPages":"7","costCenters":[],"links":[{"id":211272,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1897/06-454R1.1"},{"id":238535,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"26","issue":"6","noUsgsAuthors":false,"publicationDate":"2007-06-01","publicationStatus":"PW","scienceBaseUri":"5059f8b1e4b0c8380cd4d227","contributors":{"authors":[{"text":"Ke, R.","contributorId":51090,"corporation":false,"usgs":true,"family":"Ke","given":"R.","email":"","affiliations":[],"preferred":false,"id":429533,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Xu, Y.","contributorId":47816,"corporation":false,"usgs":true,"family":"Xu","given":"Y.","email":"","affiliations":[],"preferred":false,"id":429532,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Huang, S.","contributorId":18168,"corporation":false,"usgs":true,"family":"Huang","given":"S.","affiliations":[],"preferred":false,"id":429531,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Wang, Z.","contributorId":67976,"corporation":false,"usgs":true,"family":"Wang","given":"Z.","affiliations":[],"preferred":false,"id":429535,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Huckins, J.N.","contributorId":62553,"corporation":false,"usgs":true,"family":"Huckins","given":"J.N.","email":"","affiliations":[],"preferred":false,"id":429534,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}
