The success of early life stages, such as those of aquatic invertebrates, is highly affected by adverse environmental conditions. Silver released into the environment from emerging nanotechnology represents such a threat. Sediments are sinks for numerous pollutants, which aggregate and/or associate with depositing suspended particles. Deposit feeder such as the annelid Platynereis dumerilii, which has a large associated literature on its development, is an excellent model organism for exposure studies in coastal environments. We exposed eggs, larvae, juveniles and adults of P. dumerilii to various concentrations of citrate (cit-Ag NPs) or humic acid (HA-Ag NPs) capped silver nanoparticles (Ag NPs) as well to dissolved Ag (added as AgNO3). We showed that mortality and abnormal development rate increased with younger life stages. While adults and juvenile were the most tolerant life stages, fertilized eggs were highly sensitive to AgNO3, cit-Ag NPs and HA-Ag NPs. Exposures to HA-Ag NPs triggered the highest cute toxicity responses in P. dumerilii and in most cases both Ag NPs were more toxic than AgNO3. Uptake rate of HA-Ag NPs in adult worms was also higher than from other Ag forms, consistent with toxicity to other life stages. The early stages of the life cycle of marine coastal organisms are more affected by Ag NPs than the juvenile or adult life stages, indicating that exposure experiments at the larval level contribute to realistic eco-toxicological studies in aquatic environments.","language":"English","publisher":"Elsevier","doi":"10.1016/j.scitotenv.2014.01.039","usgsCitation":"Garcia-Alonso, J., Rodriguez-Sanchez, N., Misra, S.K., Valsami-Jones, E., Croteau, M., Luoma, S.N., and Rainbow, P.S., 2014, Toxicity and accumulation of silver nanoparticles during development of the marine polychaete Platynereis dumerilii: Science of the Total Environment, v. 476-477, p. 688-695, https://doi.org/10.1016/j.scitotenv.2014.01.039.","productDescription":"8 p.","startPage":"688","endPage":"695","ipdsId":"IP-053939","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":283209,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":283208,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.scitotenv.2014.01.039"}],"volume":"476-477","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5351706ae4b05569d805a417","contributors":{"authors":[{"text":"Garcia-Alonso, Javier","contributorId":65002,"corporation":false,"usgs":true,"family":"Garcia-Alonso","given":"Javier","email":"","affiliations":[],"preferred":false,"id":491202,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Rodriguez-Sanchez, Neus","contributorId":94974,"corporation":false,"usgs":true,"family":"Rodriguez-Sanchez","given":"Neus","email":"","affiliations":[],"preferred":false,"id":491205,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Misra, Superb K.","contributorId":91231,"corporation":false,"usgs":true,"family":"Misra","given":"Superb","email":"","middleInitial":"K.","affiliations":[],"preferred":false,"id":491204,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Valsami-Jones, Eugenia","contributorId":26057,"corporation":false,"usgs":true,"family":"Valsami-Jones","given":"Eugenia","email":"","affiliations":[],"preferred":false,"id":491201,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Croteau, Marie-Noële","contributorId":22863,"corporation":false,"usgs":true,"family":"Croteau","given":"Marie-Noële","affiliations":[],"preferred":false,"id":491200,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Luoma, Samuel N. 0000-0001-5443-5091 snluoma@usgs.gov","orcid":"https://orcid.org/0000-0001-5443-5091","contributorId":2287,"corporation":false,"usgs":true,"family":"Luoma","given":"Samuel","email":"snluoma@usgs.gov","middleInitial":"N.","affiliations":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"preferred":true,"id":491199,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Rainbow, Philip S.","contributorId":83025,"corporation":false,"usgs":true,"family":"Rainbow","given":"Philip","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":491203,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

Incision changes the magnitude and timing of streamflow in water supply source watersheds, a concern to resource managers and downstream water users. The hydrology of montane meadows under natural and incised conditions was investigated using watershed simulation for a range of hydrologic conditions. The results illustrate the interdependence between: watershed and meadow hydrology; bedrock and meadow aquifers; and surface and groundwater flow through the meadow for the modeled scenarios. During the wet season, stream incision resulted in less overland flow and interflow and more meadow recharge causing a net decrease in streamflow and increase in groundwater storage relative to natural meadow conditions. During the dry season, incision resulted in less meadow evapotranspiration and more groundwater discharge to the stream causing a net increase in streamflow and a decrease in groundwater storage relative to natural meadow conditions. In general, for a given meadow setting, the magnitude of change in summer streamflow and long-term change in watershed groundwater storage due to incision will depend on the combined effect of: reduced evapotranspiration in the eroded meadow; induced groundwater recharge; replenishment of dry season groundwater storage depletion in meadow and bedrock aquifers by precipitation during wet years; and groundwater storage depletion that is not replenished by precipitation during wet years.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Water Resources Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","doi":"10.1002/2013WR014420","usgsCitation":"Essaid, H.I., and Hill, B., 2014, Watershed-scale modeling of streamflow change in incised montane meadows: Water Resources Research, v. 50, no. 3, p. 2657-2678, https://doi.org/10.1002/2013WR014420.","productDescription":"22 p.","startPage":"2657","endPage":"2678","numberOfPages":"22","ipdsId":"IP-052739","costCenters":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"links":[{"id":295519,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":295482,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/2013WR014420"}],"country":"United States","volume":"50","issue":"3","noUsgsAuthors":false,"publicationDate":"2014-03-25","publicationStatus":"PW","scienceBaseUri":"544775d6e4b0f888a81b835c","contributors":{"authors":[{"text":"Essaid, Hedeff I. 0000-0003-0154-8628 hiessaid@usgs.gov","orcid":"https://orcid.org/0000-0003-0154-8628","contributorId":2284,"corporation":false,"usgs":true,"family":"Essaid","given":"Hedeff","email":"hiessaid@usgs.gov","middleInitial":"I.","affiliations":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"preferred":true,"id":503552,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hill, Barry R.","contributorId":62158,"corporation":false,"usgs":true,"family":"Hill","given":"Barry R.","affiliations":[],"preferred":false,"id":503553,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

One of these materials is ash, which is the particulate residue remaining or deposited on the ground that consists of mineral materials and charred organic components. The quantity and characteristics of ash produced during a wildland fire depend mainly on (1) the total burned fuel (i.e. fuel load), (2) fuel type and (3) its combustion completeness. For a given fuel load and type, a higher combustion completeness will reduce the ash organic carbon content, increasing the relative mineral content, and hence reducing total mass of ash produced. The homogeneity and thickness of the ash layer can vary substantially in space and time and reported average thicknesses range from close to 0 to 50&nbsp;mm. Ash is a highly mobile material that, after its deposition, may be incorporated into the soil profile, redistributed or removed from a burned site within days or weeks by wind and water erosion to surface depressions, footslopes, streams, lakes, reservoirs and, potentially, into marine deposits.</p><p id=\"sp0010\">Research on the composition, properties and effects of ash on the burned ecosystem has been conducted on material collected in the field after wildland and prescribed fires as well as on material produced in the laboratory. At low combustion completeness (typically T&nbsp;&lt;&nbsp;450&nbsp;°C), ash is organic-rich, with organic carbon as the main component. At high combustion completeness (T&nbsp;&gt;&nbsp;450&nbsp;°C), most organic carbon is volatized and the remaining mineral ash has elevated pH when in solution. It is composed mainly of calcium, magnesium, sodium, potassium, silicon and phosphorous in the form of inorganic carbonates, whereas at T&nbsp;&gt;&nbsp;580&nbsp;°C the most common forms are oxides. Ash produced under lower combustion completeness is usually darker, coarser, and less dense and has a higher saturated hydraulic conductivity than ash with higher combustion completeness, although physical reactions with CO<sub>2</sub><span>&nbsp;</span>and when moistened produce further changes in ash characteristics.</p><p id=\"sp0015\">As a new material present after a wildland fire, ash can have profound effects on ecosystems. It affects biogeochemical cycles, including the C cycle, not only within the burned area, but also globally. Ash incorporated into the soil increases temporarily soil pH and nutrient pools and changes physical properties such as albedo, soil texture and hydraulic properties including water repellency. Ash modifies soil hydrologic behavior by creating a two-layer system: the soil and the ash layer, which can function in different ways depending on (1) ash depth and type, (2) soil type and (3) rainfall characteristics. Key parameters are the ash's water holding capacity, hydraulic conductivity and its potential to clog soil pores. Runoff from burned areas carries soluble nutrients contained in ash, which can lead to problems for potable water supplies. Ash deposition also stimulates soil microbial activity and vegetation growth.</p><p id=\"sp0020\">Further work is needed to (1) standardize methods for investigating ash and its effects on the ecosystem, (2) characterize ash properties for specific ecosystems and wildland fire types, (3) determine the effects of ash on human and ecosystem health, especially when transported by wind or water, (4) investigate ash's controls on water and soil losses at slope and catchment scales, (5) examine its role in the C cycle, and (6) study its redistribution and fate in the environment.</p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.earscirev.2013.12.007","usgsCitation":"Bodi, M.B., Martin, D.A., Balfour, V.N., Santin, C., Doerr, S.H., Pereira, P., Cerda, A., and Mataix-Solera, J., 2014, Wildland fire ash: Production, composition and eco-hydro-geomorphic effects: Earth-Science Reviews, v. 130, p. 103-127, https://doi.org/10.1016/j.earscirev.2013.12.007.","productDescription":"25 p.","startPage":"103","endPage":"127","ipdsId":"IP-053418","costCenters":[{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true}],"links":[{"id":343399,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"130","publishingServiceCenter":{"id":2,"text":"Denver PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"595f4c42e4b0d1f9f057e360","contributors":{"authors":[{"text":"Bodi, Merche B.","contributorId":194266,"corporation":false,"usgs":false,"family":"Bodi","given":"Merche","email":"","middleInitial":"B.","affiliations":[],"preferred":false,"id":703627,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Martin, Deborah A. 0000-0001-8237-0838 damartin@usgs.gov","orcid":"https://orcid.org/0000-0001-8237-0838","contributorId":168662,"corporation":false,"usgs":true,"family":"Martin","given":"Deborah","email":"damartin@usgs.gov","middleInitial":"A.","affiliations":[{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true},{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true},{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"preferred":true,"id":703626,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Balfour, Victoria N.","contributorId":194267,"corporation":false,"usgs":false,"family":"Balfour","given":"Victoria","email":"","middleInitial":"N.","affiliations":[],"preferred":false,"id":703628,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Santin, Cristina","contributorId":194268,"corporation":false,"usgs":false,"family":"Santin","given":"Cristina","email":"","affiliations":[],"preferred":false,"id":703629,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Doerr, Stefan H.","contributorId":194269,"corporation":false,"usgs":false,"family":"Doerr","given":"Stefan","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":703630,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Pereira, Paulo","contributorId":194270,"corporation":false,"usgs":false,"family":"Pereira","given":"Paulo","email":"","affiliations":[],"preferred":false,"id":703631,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Cerda, Artemi","contributorId":194271,"corporation":false,"usgs":false,"family":"Cerda","given":"Artemi","email":"","affiliations":[],"preferred":false,"id":703632,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Mataix-Solera, Jorge","contributorId":194272,"corporation":false,"usgs":false,"family":"Mataix-Solera","given":"Jorge","email":"","affiliations":[],"preferred":false,"id":703633,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

Contamination resulting from the site operations was identified in groundwater, soil, and sediment. Vincent Spring, used as a public water supply by the city of Vincent, Alabama, is located about ½ mile southwest of the site. The U.S. Geological Survey, in cooperation with the U.S. Environmental Protection Agency, conducted an investigation at Vincent Spring and the Alabama Plating site, Vincent, Alabama, during 2007–2008 to evaluate the groundwater quality and evaluate the potential effect of contaminated groundwater on the water quality of Vincent Spring.

Here we used a three-pronged approach to study the in vivo retention and efflux kinetics of 20 nm citrate stabilized Au NPs ingested by this key aquatic species. Daphnids were exposed to suspended particles (600 μg L<sup>−1</sup>) for 5 h after which they were depurated for 24 h in clean water containing algae. Light microscopy was used to follow the passage of Au NPs through the gastrointestinal tract, Au body burdens were determined by ICP-MS (inductively coupled plasma mass spectrometry), and transmission electron microscopy (TEM) was used to examine the presence and distribution of Au NPs in tissues. Results revealed that the elimination of Au NPs was bi-phasic. The fast elimination phase lasted <1 h and the rate constant at which Au (of Au NPs) was eliminated was 1.12 ± 0.34 h<sup>−1</sup> (±SE) which accounted for ∼75% of the ingested Au. The remaining ∼25% of the ingested Au NPs was eliminated at a 100-fold slower rate. TEM analysis revealed that Au NPs in the midgut were in close proximity to the peritrophic membrane after 1 and 24 h of depuration. There were no observations of Au NP uptake at the microvilli. Thus, although Au NPs were retained in the gut lumen, there was no observable internalization into the gut epithelial cells. Similar to carbon nanotubes and CuO NPs, our findings indicate that in daphnids the in vivo retention of Au NPs does not necessarily result in their internalization.","language":"English","publisher":"Chemosphere","doi":"10.1016/j.chemosphere.2013.12.051","usgsCitation":"Khan, F.R., Kennaway, G.M., Croteau, M., Dybowska, A., Smith, B.D., Nogueira, A.J., Rainbow, P.S., Luoma, S.N., and Valsami-Jones, E., 2014, In vivo retention of ingested Au NPs by Daphnia magna: No evidence for trans-epithelial alimentary uptake: Chemosphere, v. 100, p. 97-104, https://doi.org/10.1016/j.chemosphere.2013.12.051.","productDescription":"8 p.","startPage":"97","endPage":"104","ipdsId":"IP-053139","costCenters":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true},{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":283200,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":283199,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.chemosphere.2013.12.051"}],"volume":"100","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5351706fe4b05569d805a455","contributors":{"authors":[{"text":"Khan, Farhan R.","contributorId":99464,"corporation":false,"usgs":true,"family":"Khan","given":"Farhan","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":491197,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kennaway, Gabrielle M.","contributorId":71879,"corporation":false,"usgs":true,"family":"Kennaway","given":"Gabrielle","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":491195,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Croteau, Marie-Noële","contributorId":22863,"corporation":false,"usgs":true,"family":"Croteau","given":"Marie-Noële","affiliations":[],"preferred":false,"id":491191,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Dybowska, Agnieszka","contributorId":34041,"corporation":false,"usgs":true,"family":"Dybowska","given":"Agnieszka","affiliations":[],"preferred":false,"id":491193,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Smith, Brian D.","contributorId":103575,"corporation":false,"usgs":true,"family":"Smith","given":"Brian","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":491198,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Nogueira, Antonio J.A.","contributorId":58940,"corporation":false,"usgs":true,"family":"Nogueira","given":"Antonio","email":"","middleInitial":"J.A.","affiliations":[],"preferred":false,"id":491194,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Rainbow, Philip S.","contributorId":83025,"corporation":false,"usgs":true,"family":"Rainbow","given":"Philip","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":491196,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Luoma, Samuel N. 0000-0001-5443-5091 snluoma@usgs.gov","orcid":"https://orcid.org/0000-0001-5443-5091","contributorId":2287,"corporation":false,"usgs":true,"family":"Luoma","given":"Samuel","email":"snluoma@usgs.gov","middleInitial":"N.","affiliations":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"preferred":true,"id":491190,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Valsami-Jones, Eugenia","contributorId":26057,"corporation":false,"usgs":true,"family":"Valsami-Jones","given":"Eugenia","email":"","affiliations":[],"preferred":false,"id":491192,"contributorType":{"id":1,"text":"Authors"},"rank":9}]}}

Yet, the net balance of MeHg sources and sinks in seasonal wetland environments is poorly understood because it requires an annual, integrated assessment across biota, sediment, and water components. We examined a suite of wetlands managed for rice crops or wildlife during 2007–2008 in California's Central Valley, in an area affected by Hg contamination from historic mining practices. Hydrologic management of agricultural wetlands for rice, wild rice, or fallowed — drying for field preparation and harvest, and flooding for crop growth and post-harvest rice straw decay — led to pronounced seasonality in sediment and aqueous MeHg concentrations that were up to 95-fold higher than those measured concurrently in adjacent, non-agricultural permanently-flooded and seasonally-flooded wetlands. Flooding promoted microbial MeHg production in surface sediment of all wetlands, but extended water residence time appeared to preferentially enhance MeHg degradation and storage. When incoming MeHg loads were elevated, individual fields often served as a MeHg sink, rather than a source. Slow, horizontal flow of shallow water in the agricultural wetlands led to increased importance of vertical hydrologic fluxes, including evapoconcentration of surface water MeHg and transpiration-driven advection into the root zone, promoting temporary soil storage of MeHg. Although this hydrology limited MeHg export from wetlands, it also increased MeHg exposure to resident fish via greater in situ aqueous MeHg concentrations. Our results suggest that the combined traits of agricultural wetlands — slow-moving shallow water, manipulated flooding and drying, abundant labile plant matter, and management for wildlife — may enhance microbial methylation of Hg(II) and MeHg exposure to local biota, as well as export to downstream habitats during uncontrolled winter-flow events.","language":"English","publisher":"Elsevier","doi":"10.1016/j.scitotenv.2014.01.033","usgsCitation":"Windham-Myers, L., Fleck, J., Ackerman, J., Marvin-DiPasquale, M.C., Stricker, C.A., Heim, W.A., Bachand, P., Eagles-Smith, C.A., Gill, G., Stephenson, M., and Alpers, C.N., 2014, Mercury cycling in agricultural and managed wetlands: a synthesis of methylmercury production, hydrologic export, and bioaccumulation from an integrated field study: Science of the Total Environment, v. 484, p. 221-231, https://doi.org/10.1016/j.scitotenv.2014.01.033.","productDescription":"11 p.","startPage":"221","endPage":"231","numberOfPages":"11","ipdsId":"IP-052623","costCenters":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true},{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true},{"id":438,"text":"National Research Program -

The Choptank River estuary, a Bay tributary on the eastern shore, is one such waterway, where corn and soybean production in upland areas of the watershed contribute significant loads of nutrients and sediment to streams. We adopted a novel approach utilizing the relationship between the concentration of nitrate-N and the stable, water-soluble herbicide degradation product MESA {2-[2-ethyl-N-(1-methoxypropan-2-yl)-6-methylanilino]-2-oxoethanesulfonic acid} to distinguish between dilution and denitrification effects on the stream concentration of nitrate-N in agricultural subwatersheds. The ratio of mean nitrate-N concentration/(mean MESA concentration * 1000) for 15 subwatersheds was examined as a function of percent cropland on hydric soil. This inverse relationship (R<sup>2</sup> = 0.65, p < 0.001) takes into consideration not only dilution and denitrification of nitrate-N, but also the stream sampling bias of the croplands caused by extensive drainage ditch networks. MESA was also used to track nitrate-N concentrations within the estuary of the Choptank River. The relationship between nitrate-N and MESA concentrations in samples collected over three years was linear (0.95 ≤ R<sup>2</sup> ≤ 0.99) for all eight sampling dates except one where R<sup>2</sup> = 0.90. This very strong correlation indicates that nitrate-N was conserved in much of the Choptank River estuary, that dilution alone is responsible for the changes in nitrate-N and MESA concentrations, and more importantly nitrate-N loads are not reduced in the estuary prior to entering the Chesapeake Bay. Thus, a critical need exists to minimize nutrient export from agricultural production fields and to identify specific conservation practices to address the hydrologic conditions within each subwatershed. In well drained areas, removal of residual N within the cropland is most critical, and practices such as cover crops which sequester the residual N should be strongly encouraged. In poorly drained areas where denitrification can occur, wetland restoration and controlled drained structures that minimize ditch flow should be used to maximize denitrification.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Science of the Total Environment","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.scitotenv.2013.12.017","usgsCitation":"McCarty, G.W., Hapeman, C.J., Rice, C.P., Hively, W., McConnell, L.L., Sadeghi, A.M., Lang, M., Whitall, D.R., Bialek, K., and Downey, P., 2014, Metolachlor metabolite (MESA) reveals agricultural nitrate-N fate and transport in Choptank River watershed: Science of the Total Environment, v. 473-474, p. 473-482, https://doi.org/10.1016/j.scitotenv.2013.12.017.","productDescription":"10 p.","startPage":"473","endPage":"482","ipdsId":"IP-024932","costCenters":[{"id":242,"text":"Eastern Geographic Science Center","active":true,"usgs":true}],"links":[{"id":282295,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":282294,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.scitotenv.2013.12.017"},{"id":282286,"type":{"id":15,"text":"Index Page"},"url":"https://www.sciencedirect.com/science/article/pii/S004896971301471X#"}],"state":"Delaware;Maryl","otherGeospatial":"Choptank River Watershed","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -76.1834,37.9472 ], [ -76.1834,39.4227 ], [ -75.0606,39.4227 ], [ -75.0606,37.9472 ], [ -76.1834,37.9472 ] ] ] } } ] }","volume":"473-474","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53517055e4b05569d805a32d","contributors":{"authors":[{"text":"McCarty, Gregory W.","contributorId":78861,"corporation":false,"usgs":true,"family":"McCarty","given":"Gregory","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":490168,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hapeman, Cathleen J.","contributorId":63154,"corporation":false,"usgs":true,"family":"Hapeman","given":"Cathleen","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":490167,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Rice, Clifford P.","contributorId":56594,"corporation":false,"usgs":true,"family":"Rice","given":"Clifford","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":490164,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hively, W.

A key challenge is to improve the predictability of postdisturbance biogeochemical trajectories at the ecosystem level. Ecosystem ecologists and paleoecologists have generated complementary data sets about disturbance (type, severity, frequency) and ecosystem response (net primary productivity, nutrient cycling) spanning decadal to millennial timescales. Here, we take the first steps toward a full integration of these data sets by reviewing how disturbances are reconstructed using dendrochronological and sedimentary archives and by summarizing the conceptual frameworks for carbon, nitrogen, and hydrologic responses to disturbances. Key research priorities include further development of paleoecological techniques that reconstruct both disturbances and terrestrial ecosystem dynamics. In addition, mechanistic detail from disturbance experiments, long-term observations, and chronosequences can help increase the understanding of ecosystem resilience.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"BioScience","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"American Institute of

Because of fire, introduced ungulates and landscape-level invasion of non-native grasses, less than 10% of original dry forest (~730&thinsp;mm precipitation annually) still exists on leeward Haleakalā, Maui, Hawaiian Islands. Native dry forest restoration at Auwahi has demonstrated the potential for dramatic revegetation, allowing a unique experimental comparison of hydrologic function between tracts of restored forest and adjacent grasslands. We hypothesized that even relatively recent forest restoration can assist in the recovery of impaired hydrologic function, potentially increasing aquifer recharge. To compare restored forest and grassland sites, we experimentally irrigated and measured soil moisture and temperature with subsurface instrumentation at four locations within the reforested area and four within the grassland, each with a 2&middot;5&thinsp;&times;&thinsp;2&middot;5-m plot. Compared with grassland areas, water in reforested sites moved to depth faster with larger magnitude changes in water content.

The effectiveness of depressional wetlands at mitigating nitrate (NO<sub>3</sub>) transport from fertilized row crops, through groundwater, to local streams was examined in the watershed of the upper Choptank River, a tributary of Chesapeake Bay on the Atlantic Coastal Plain. Hydrologic, geochemical, and water quality data were collected from January of 2008 through December of 2009 from surface waters and networks of piezometers installed in and around current or former depressional wetlands of three major types along a gradient of anthropogenic alteration: (1) natural wetlands with native vegetation (i.e., forested); (2) prior-converted croplands, which are former wetlands located in cultivated fields; and (3) hydrologically restored wetlands, including one wetland restoration and one shallow water management area. These data were collected to estimate the orientation of groundwater flow paths and likely interactions of groundwater containing NO<sub>3</sub> from agricultural sources with reducing conditions associated with wetlands of different types. Natural wetlands were found to have longer periods of soil saturation and reducing conditions conducive to denitrification compared to the other wetland types studied. Because natural wetlands are typically located in groundwater recharge areas along watershed divides, nitrogen (N) from nearby agriculture was not intercepted. However, these wetlands likely improve water quality in adjacent streams via dilution. Soil and geochemical conditions conducive to denitrification were also present in restored wetlands and prior-converted croplands, and substantial losses of agricultural NO<sub>3</sub> were observed in groundwater flowing through these wetland sediments. However, delivery of NO<sub>3</sub> from agricultural areas through groundwater to these wetlands resulting in opportunities for denitrification were limited, particularly where reducing conditions did not extend throughout the entire thickness of the surficial aquifer allowing NO<sub>3</sub> to pass conservatively beneath a wetland along deeper groundwater flow paths. The complexity of N fate and transport associated with depressional wetlands complicates the understanding of their importance to water quality in adjacent streams. Although depressional wetlands often contribute low NO<sub>3</sub> water to local streams, their effectiveness as landscape sinks, for N from adjacent agriculture varies with natural conditions, such as the thickness of the aquifer and the extent of reducing conditions. Measurement of such natural geologic, hydrologic, and geochemical conditions are therefore fundamental to understanding N mitigation in individual wetlands.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Soil and Water Conservation","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Soil and Water Conservation Society","doi":"10.2489/jswc.69.1.1","usgsCitation":"Denver, J.M., Ator, S., Lang, M., Fisher, T., Gustafson, A., Fox, R., Clune, J., and McCarty, G., 2014, Nitrate fate and transport through current and former depressional wetlands in an agricultural landscape, Choptank Watershed, Maryland, United States: Journal of Soil and Water Conservation, v. 69, no. 1, p. 1-16, https://doi.org/10.2489/jswc.69.1.1.","productDescription":"16 p.","startPage":"1","endPage":"16","numberOfPages":"16","ipdsId":"IP-037456","costCenters":[{"id":374,"text":"Maryland Water Science Center","active":true,"usgs":true}],"links":[{"id":473180,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.2489/jswc.69.1.1","text":"Publisher Index Page"},{"id":289338,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":289305,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2489/jswc.69.1.1"}],"country":"United States","state":"Maryl","otherGeospatial":"Choptank River;Choptank Watershed","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -76.3577,38.5417 ], [ -76.3577,39.2014 ], [ -75.5928,39.2014 ], [ -75.5928,38.5417 ], [ -76.3577,38.5417 ] ] ] } } ] }","volume":"69","issue":"1","noUsgsAuthors":false,"publicationDate":"2014-01-06","publicationStatus":"PW","scienceBaseUri":"53b3d86ae4b07c5f79a7f348","contributors":{"authors":[{"text":"Denver, J.

The historical oscillation (~13y) is remarkably consistent among small seepage lakes, groundwater tables and the two largest Laurentian Great Lakes despite substantial differences in hydrology. Hydrologic analyses indicate that the oscillation has been governed primarily by changes in the net atmospheric flux of water (P-E) and stage-dependent outflow. The oscillation is hypothetically connected to large-scale atmospheric circulation patterns originating in the mid-latitude North Pacific that support the flux of moisture into the region from the Gulf of Mexico. Recent data indicate an apparent change in the historical oscillation characterized by a ~12y downward trend beginning in 1998. Record low water levels region-wide may mark the onset of a new hydroclimatic regime.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geophysical Research Letters","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","doi":"10.1002/2013GL058679","usgsCitation":"Watras, C., Read, J., Holman, K., Liu, Z., Song, Y., Watras, A., Morgan, S., and Stanley, E., 2014, Decadal oscillation of lakes and aquifers in the upper Great Lakes region of North America: hydroclimatic implications: Geophysical Research Letters, v. 41, no. 2, p. 456-462, https://doi.org/10.1002/2013GL058679.","productDescription":"7 p.","startPage":"456","endPage":"462","numberOfPages":"7","ipdsId":"IP-051171","costCenters":[{"id":160,"text":"Center for Integrated Data Analytics","active":false,"usgs":true}],"links":[{"id":473188,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1002/2013gl058679","text":"Publisher Index Page"},{"id":286507,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":286489,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/2013GL058679"}],"country":"United States","otherGeospatial":"Upper Great Lakes Region","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -93.8,40.95 ], [ -93.8,49.14 ], [ -79.71,49.14 ], [ -79.71,40.95 ], [ -93.8,40.95 ] ] ] } } ] }","volume":"41","issue":"2","noUsgsAuthors":false,"publicationDate":"2014-01-21","publicationStatus":"PW","scienceBaseUri":"53578f63e4b0938066bc81ca","contributors":{"authors":[{"text":"Watras, C.J.","contributorId":13917,"corporation":false,"usgs":true,"family":"Watras","given":"C.J.","email":"","affiliations":[],"preferred":false,"id":492973,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Read, J.S.","contributorId":34440,"corporation":false,"usgs":true,"family":"Read","given":"J.S.","email":"","affiliations":[],"preferred":false,"id":492976,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Holman, K.D.","contributorId":60548,"corporation":false,"usgs":true,"family":"Holman","given":"K.D.","email":"","affiliations":[],"preferred":false,"id":492977,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Liu, Z.","contributorId":70943,"corporation":false,"usgs":true,"family":"Liu","given":"Z.","email":"","affiliations":[],"preferred":false,"id":492978,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Song, Y.-Y.","contributorId":77056,"corporation":false,"usgs":true,"family":"Song","given":"Y.-Y.","email":"","affiliations":[],"preferred":false,"id":492979,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Watras, A.J.","contributorId":31315,"corporation":false,"usgs":true,"family":"Watras","given":"A.J.","email":"","affiliations":[],"preferred":false,"id":492975,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Morgan, S.","contributorId":81026,"corporation":false,"usgs":true,"family":"Morgan","given":"S.","email":"","affiliations":[],"preferred":false,"id":492980,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Stanley, E.H.","contributorId":18966,"corporation":false,"usgs":true,"family":"Stanley","given":"E.H.","email":"","affiliations":[],"preferred":false,"id":492974,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

Few studies have explored how interactions of biogeochemical transformations, various nitrogen sources, and catchment flow paths affect stream nitrogen variation during autumn. To provide more information on this critical period, we studied (1) the timing, duration, and magnitude of changes to stream nitrate, dissolved organic nitrogen (DON), and ammonium concentrations; (2) changes in nitrate sources and cycling; and (3) source areas of the landscape that most influence stream nitrogen. We collected samples at higher temporal resolution for a longer duration than typical studies of stream nitrogen during autumn. This sampling scheme encompassed the patterns and extremes that occurred during base flow and stormflow events of autumn. Base flow nitrate concentrations decreased by an order of magnitude from 5.4 to 0.7 &micro;mol L</span><sup>&minus;1</sup><span><span class=\"Apple-converted-space\">&nbsp;</span>during the week when most leaves fell from deciduous trees. Changes to rates of biogeochemical transformations during autumn base flow explained the low nitrate concentrations; in-stream transformations retained up to 72% of the nitrate that entered a stream reach. A decrease of in-stream nitrification coupled with heterotrophic nitrate cycling were primary factors in the seasonal nitrate decline. The period of low nitrate concentrations ended with a storm event in which stream nitrate concentrations increased by 25-fold. In the ensuing weeks, peak stormflow nitrate concentrations progressively decreased over closely spaced, yet similarly sized events. Most stormflow nitrate originated from nitrification in near-stream areas with occasional, large inputs of unprocessed atmospheric nitrate, which has rarely been reported for nonsnowmelt events. A maximum input of 33% unprocessed atmospheric nitrate to the stream occurred during one event. Large inputs of unprocessed atmospheric nitrate show direct and rapid effects on forest streams that may be widespread, although undocumented, throughout nitrogen-polluted temperate forests. In contrast to a week-long nitrate decline during peak autumn litterfall, base flow DON concentrations increased after leaf fall and remained high for 2 months. Dissolved organic nitrogen was hydrologically flushed to the stream from riparian soils during stormflow. In contrast to distinct seasonal changes in base flow nitrate and DON concentrations, ammonium concentrations were typically at or below the detection limit, similar to the rest of the year. Our findings reveal couplings among catchment flow paths, nutrient sources, and transformations that control seasonal extremes of stream nitrogen in forested landscapes.</span></p>","language":"English","publisher":"Wiley-Blackwell Publishing, Inc.","doi":"10.1002/2013WR013670","usgsCitation":"Sebestyen, S.D., Shanley, J.B., Boyer, E.W., Kendall, C., and Doctor, D.H., 2014, Coupled hydrological and biogeochemical processes controlling variability of nitrogen species in streamflow during autumn in an upland forest: Water Resources Research, v. 50, no. 2, p. 1569-1591, https://doi.org/10.1002/2013WR013670.","productDescription":"23 p.","startPage":"1569","endPage":"1591","numberOfPages":"23","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-051358","costCenters":[{"id":405,"text":"NH/VT office of New England Water Science Center","active":true,"usgs":true}],"links":[{"id":473199,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1002/2013wr013670","text":"Publisher Index Page"},{"id":299159,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Vermont","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -72.13794708251953,\n              44.51878604321945\n            ],\n            [\n              -72.22721099853516,\n              44.39625939021994\n            ],\n            [\n              -72.16850280761719,\n              44.38521938054099\n            ],\n            [\n              -72.17056274414062,\n              44.37196862007497\n            ],\n            [\n              -72.09468841552734,\n              44.35773298166116\n            ],\n            [\n              -72.04627990722656,\n              44.39895774251037\n            ],\n            [\n              -72.08404541015625,\n              44.51070720877548\n            ],\n            [\n              -72.13794708251953,\n              44.51878604321945\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"50","issue":"2","publishingServiceCenter":{"id":11,"text":"Pembroke PSC"},"noUsgsAuthors":false,"publicationDate":"2014-02-24","publicationStatus":"PW","scienceBaseUri":"551a75cde4b0323842783502","contributors":{"authors":[{"text":"Sebestyen, Stephen D.","contributorId":107562,"corporation":false,"usgs":true,"family":"Sebestyen","given":"Stephen","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":543654,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Shanley, James B. 0000-0002-4234-3437 jshanley@usgs.gov","orcid":"https://orcid.org/0000-0002-4234-3437","contributorId":1953,"corporation":false,"usgs":true,"family":"Shanley","given":"James","email":"jshanley@usgs.gov","middleInitial":"B.","affiliations":[{"id":466,"text":"New England Water Science Center","active":true,"usgs":true},{"id":405,"text":"NH/VT office of New England Water Science Center","active":true,"usgs":true}],"preferred":true,"id":543655,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Boyer, Elizabeth W.","contributorId":44659,"corporation":false,"usgs":false,"family":"Boyer","given":"Elizabeth","email":"","middleInitial":"W.","affiliations":[{"id":7260,"text":"Pennsylvania State University","active":true,"usgs":false}],"preferred":false,"id":543656,"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":543657,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Doctor, Daniel H. 0000-0002-8338-9722 dhdoctor@usgs.gov","orcid":"https://orcid.org/0000-0002-8338-9722","contributorId":2037,"corporation":false,"usgs":true,"family":"Doctor","given":"Daniel","email":"dhdoctor@usgs.gov","middleInitial":"H.","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":543658,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Much research has gone into evaluating the fate and transport of these contaminants, but this work has often assumed constant flow from wastewater treatment plants. However, effluent discharge commonly varies widely over a 24-hour period, and this variation controls contaminant loading and can profoundly influence interpretations of environmental data. We show that methodologies relying on the normalization of downstream data to conservative elements can give spurious results, and should not be used unless it can be verified that the same parcel of water was sampled. Lagrangian sampling, which in theory samples the same water parcel as it moves downstream (the Lagrangian parcel), links hydrologic and chemical transformation processes so that the in-stream fate of wastewater contaminants can be quantitatively evaluated. However, precise Lagrangian sampling is difficult, and small deviations – such as missing the Lagrangian parcel by less than 1</span><span>&nbsp;</span><span>h – can cause large differences in measured concentrations of all dissolved compounds at downstream sites, leading to erroneous conclusions regarding in-stream processes controlling the fate and transport of wastewater contaminants. Therefore, we have developed a method termed “verified Lagrangian” sampling, which can be used to determine if the Lagrangian parcel was actually sampled, and if it was not, a means for correcting the data to reflect the concentrations which would have been obtained had the Lagrangian parcel been sampled. To apply the method, it is necessary to have concentration data for a number of conservative constituents from the upstream, effluent, and downstream sites, along with upstream and effluent concentrations that are constant over the short-term (typically 2–4</span><span>&nbsp;</span><span>h). These corrections can subsequently be applied to all data, including non-conservative constituents. Finally, we show how data from other studies can be corrected.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.scitotenv.2013.09.079","usgsCitation":"Antweiler, R.C., Writer, J.H., and Murphy, S.F., 2014, Evaluation of wastewater contaminant transport in surface waters using verified Lagrangian sampling: Science of the Total Environment, v. 470-471, p. 551-558, https://doi.org/10.1016/j.scitotenv.2013.09.079.","productDescription":"8 p.","startPage":"551","endPage":"558","ipdsId":"IP-042105","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true},{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true}],"links":[{"id":344087,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"470-471","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"59706fbce4b0d1f9f065a8fd","contributors":{"authors":[{"text":"Antweiler, Ronald C. 0000-0001-5652-6034 antweil@usgs.gov","orcid":"https://orcid.org/0000-0001-5652-6034","contributorId":1481,"corporation":false,"usgs":true,"family":"Antweiler","given":"Ronald","email":"antweil@usgs.gov","middleInitial":"C.","affiliations":[{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true}],"preferred":true,"id":705757,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Writer, Jeffrey H. jwriter@usgs.gov","contributorId":1393,"corporation":false,"usgs":true,"family":"Writer","given":"Jeffrey","email":"jwriter@usgs.gov","middleInitial":"H.","affiliations":[{"id":595,"text":"U.S. Geological Survey","active":false,"usgs":true}],"preferred":false,"id":705758,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Murphy, Sheila F. 0000-0002-5481-3635 sfmurphy@usgs.gov","orcid":"https://orcid.org/0000-0002-5481-3635","contributorId":1854,"corporation":false,"usgs":true,"family":"Murphy","given":"Sheila","email":"sfmurphy@usgs.gov","middleInitial":"F.","affiliations":[{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true},{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true}],"preferred":true,"id":705759,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

With climate change intensifying the hydrologic cycle and altering the distribution and frequency of rainfall, the problem of water availability and access will increase further. Famine&nbsp;Early Warning Systems&nbsp;Network (FEWS NET) funded by the United States Agency for International Development (USAID) has initiated a large-scale project to monitor small to medium surface water points in Africa. Under this project, multisource satellite data and hydrologic modeling techniques are integrated to monitor several hundreds of small to medium surface water points in Africa. This approach has been already tested to operationally monitor 41 water points in East Africa. The validation of modeled scaled depths with field-installed gauge data demonstrated the ability of the model to capture both the spatial patterns and seasonal variations. Modeled scaled estimates captured up to 60 % of the observed gauge variability with a mean root-mean-square error (RMSE) of 22 %. The data on relative water level, precipitation, and evapotranspiration (ETo) for water points in&nbsp;East and West&nbsp;Africa were modeled since 1998 and current information is being made available in near-real time. This chapter presents the approach, results from the East African study, and the first phase of expansion activities in the West Africa region. The water point monitoring network will be further expanded to cover much of sub-Saharan Africa. The goal of this study is to provide timely information on the water availability that would support already established FEWS NET activities in Africa. This chapter also presents the potential improvements in modeling approach to be implemented during future expansion in Africa.</p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Nile

Because water quality can affect pupfish and the environmental conditions of their habitat, a comprehensive compilation of hydrologic data for pupfish habitat and nonhabitat areas in the northern Tularosa Basin was undertaken by the U.S. Geological Survey in cooperation with White Sands Missile Range.</p>\n<br/>\n<p>The four locations within the Tularosa Basin that are known pupfish habitat areas are the Salt Creek, Malpais Spring and Malpais Salt Marsh, Main Mound Spring, and Lost River habitat areas. Streamflow data from the Salt Creek near Tularosa streamflow-gaging station indicated that the average annual mean streamflow and average annual total streamflow for water years 1995–2008 were 1.35 cubic feet per second (ft<sup>3</sup>/s) and 983 acre-feet, respectively. Periods of no flow were observed in water years 2002 through 2006.

Dissolved-solids concentrations for 16 Malpais Spring samples ranged from 3,882 to 5,500 mg/L.

Dissolved-solids concentrations in samples collected between 1955 and 2007 ranged from an estimated 3,760 to 4,240 mg/L in the upper pond and 4,840 to 5,120 mg/L in the lower pond. Isotopic data for a Main Mound Spring water sample collected in 1982 indicated that the water was about 19,600 years old.</p>\n<br/>\n<p>Dissolved-solids concentrations of Lost River samples collected from 1984 to 1999 ranged from 8,930 to 118,000 (estimated) mg/L.</p>\n<br/>\n<p>Dissolved-solids concentrations in samples from nonhabitat area sites ranged from 1,740 to 54,200 (estimated) mg/L.

Recent studies that project streamf low changes in the Colorado River all project annual declines, but the magnitude of the projected decreases range from less than 10% to 45% by the mid-twenty-first century. To understand these differences, we address the questions the management community has raised: Why is there such a wide range of projections of impacts of future climate change on Colorado River streamflow, and how should this uncertainty be interpreted? We identify four major sources of disparities among studies that arise from both methodological and model differences. In order of importance, these are differences in 1) the global climate models (GCMs) and emission scenarios used; 2) the ability of land surface and atmospheric models to simulate properly the high-elevation runoff source areas; 3) the sensitivities of land surface hydrology models to precipitation and temperature changes; and 4) the methods used to statistically downscale GCM scenarios. In accounting for these differences, there is substantial evidence across studies that future Colorado River streamflow will be reduced under the current trajectories of anthropogenic greenhouse gas emissions because of a combination of strong temperature-induced runoff curtailment and reduced annual precipitation. Reconstructions of preinstrumental streamflows provide additional insights; the greatest risk to Colorado River streamf lows is a multidecadal drought, like that observed in paleoreconstructions, exacerbated by a steady reduction in flows due to climate change. This could result in decades of sustained streamflows much lower than have been observed in the ~100 years of instrumental record.","language":"English","publisher":"American Meteorological Society","doi":"10.1175/BAMS-D-12-00228.1","usgsCitation":"Julie A.

The alpine landscape is heavily glacierized, and storage and turnover of water by glaciers substantially influences the regional surface water balance (Neal et al. 2010). In turn, the land-to-ocean flux of freshwater impacts the biogeochemistry, physical oceanography, freshwater and marine ecology of the downstream components of the GOA ecosystem (e.g., Royer et al. 2001; Hood and Scott 2008). In this way, the links between terrestrial and ocean ecosystems along the GOA have widespread impacts on regional socioeconomic issues including water and hydropower resources, fish populations, and sea level change (Dorava and Milner 2000; Royer and Grosch 2006; Cherry et al. 2010; Gardner et al. 2013). Moreover, predicting future changes in physical, chemical and biological processes in near-shore ecosystems along the GOA hinges, in part, on developing a robust understanding of water storage and transfer by glaciers through streams to the ocean.\nGlacierized basins (i.e. presently ice covered as opposed to glaciated, or historically ice covered) are very efficient producers of runoff, yielding 2–10 times greater runoff than similarly sized, non-glacierized basins (Mayo 1984). The unique energy balance that characterizes these basins (Jansson et al. 2003; Hock 2005) results in substantial alterations to streamflow, even when fractional ice coverage is very small (Stahl and Moore 2006). Consistent and precise treatment of glacier runoff is key to accurate assessment of hydrologic, ecological and socioeconomic impacts, but previously used definitions for glacier runoff are variable. They include: 1) meltwater produced as negative annual mass balance (e.g., Fountain and Tangborn 1985); 2) storage changes in the monthly water budget, where solid precipitation is balanced by melt and evaporation (Huss 2011, concept #2); 3) meltwater derived from melting ice only (irrespective of melting snow or mass balance) (Nolin et al. 2010; Huss 2011, concept #1); 4) all meltwater derived from the glacier surface (Cogley et al. 2011, meltwater runoff); 5) total runoff from the glacier surface (meltwater runoff plus rain on the glacier) (Neal et al. 2010).\nTotal glacier runoff (Definitions 4 and 5 above) includes a contribution from annual mass balance, i.e. the sum of accumulation and ablation through a mass balance year (Definition 1), or what has historically been referred to as the “net” balance (Cogley et al. 2011). Indeed, annual balance has been shown to be an important driver of streamflow trends in glacierized basins, with periods of persistent negative annual balance resulting in statistically significant increases in streamflow (e.g., Pellicciotti et al. 2010). However, in maritime climates, anomalies in glacier runoff can be disconnected from annual balance because of the high variability in winter precipitation. For example, positive anomalies in winter accumulation can result in elevated levels of glacier runoff in times of positive annual mass balance (Thayyen and Gergan 2010).\nQuantifying the impacts of changing glacier geometries (annual balance) on glacier runoff is essential for predicting future changes in streamflow in glacierized basins. However, determining the role that this component plays in total glacier runoff (Definition 5) requires consistent measurements of seasonal (or shorter period) mass balances, measurements of precipitation at multiple locations within a basin, and streamflow measurements in close proximity to a glacier’s terminus. Practical and logistical challenges associated with assembling such data sets typically preclude such partitioning. As a result, most analyses of the relationship between annual mass balance and streamflow rely on some component of model output to compute glacier runoff (e.g. Huss et al. 2008; Kaser et al. 2010). Ultimately, developing an understanding of how total glacier runoff will change in the future is critical for predicting downstream ecological impacts associated with changes in riverine fluxes of water, sediment, and solutes (e.g., metals and nutrients) to near-shore coastal ecosystems.\nThe purpose of this paper is to evaluate relationships among seasonal and annual glacier mass balances, glacier runoff and streamflow in two glacierized basins in different climate settings. We use long-term glacier mass balance and streamflow datasets from the United States Geological Survey (USGS) Alaska Benchmark Glacier Program to compare and contrast glacier-streamflow interactions in a maritime climate (Wolverine Glacier) with those in a continental climate (Gulkana Glacier). Our overall goal is to improve our understanding of how glacier mass balance processes impact streamflow, ultimately improving our conceptual understanding of the future evolution of glacier runoff in continental and maritime climates.","language":"English","publisher":"Springer","doi":"10.1007/s10584-013-1042-7","usgsCitation":"O’Neel, S., Hood, E., Arendt, A., and Sass, L., 2014, Assessing streamflow sensitivity to variations in glacier mass balance: Climatic Change, v. 123, no. 2, p. 329-341, https://doi.org/10.1007/s10584-013-1042-7.","productDescription":"13 p.","startPage":"329","endPage":"341","ipdsId":"IP-049370","costCenters":[{"id":120,"text":"Alaska Science Center Water","active":true,"usgs":true}],"links":[{"id":473202,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1007/s10584-013-1042-7","text":"Publisher Index Page"},{"id":281844,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":281842,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10584-013-1042-7"}],"country":"United States","state":"Alaska","volume":"123","issue":"2","noUsgsAuthors":false,"publicationDate":"2014-01-30","publicationStatus":"PW","scienceBaseUri":"53517024e4b05569d805a161","contributors":{"authors":[{"text":"O’Neel, Shad 0000-0002-9185-0144 soneel@usgs.gov","orcid":"https://orcid.org/0000-0002-9185-0144","contributorId":166740,"corporation":false,"usgs":true,"family":"O’Neel","given":"Shad","email":"soneel@usgs.gov","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":107,"text":"Alaska Climate Science Center","active":true,"usgs":true},{"id":120,"text":"Alaska Science Center Water","active":true,"usgs":true},{"id":622,"text":"Washington Water Science Center","active":true,"usgs":true}],"preferred":true,"id":488826,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hood, Eran","contributorId":106802,"corporation":false,"usgs":false,"family":"Hood","given":"Eran","affiliations":[],"preferred":false,"id":488828,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Arendt, Anthony","contributorId":74661,"corporation":false,"usgs":true,"family":"Arendt","given":"Anthony","affiliations":[],"preferred":false,"id":488827,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Sass, Louis C. 0000-0003-4677-029X lsass@usgs.gov","orcid":"https://orcid.org/0000-0003-4677-029X","contributorId":3555,"corporation":false,"usgs":true,"family":"Sass","given":"Louis C.","email":"lsass@usgs.gov","affiliations":[{"id":120,"text":"Alaska Science Center Water","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":488825,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Thermal infrared aerial remote sensing surveys illustrated the presence of multiple submarine groundwater discharge sites in Okatee headwaters. Significant relationships were observed between groundwater geochemical constituents and <sup>226</sup>Ra activity in groundwater with higher <sup>226</sup>Ra activity correlated to higher concentrations of organics, dissolved inorganic carbon, nutrients, and trace gases to the Okatee system. A system-level radium mass balance confirmed a substantial submarine groundwater discharge contribution of these constituents to the Okatee River. Diffusive benthic flux measurements and potential denitrification rate assays tracked the fate of constituents in creek bank sediments. Diffusive benthic fluxes were substantially lower than calculated radium-based submarine groundwater discharge inputs, showing that advection of groundwater-derived nutrients dominated fluxes in the system. While a considerable potential for denitrification in tidal creek bank sediments was noted, in situ denitrification rates were nitrate-limited, making intertidal sediments an inefficient nitrogen sink in this system. Groundwater geochemical data indicated significant differences in groundwater chemical composition and radium activity ratios between the eastern and western sides of the river; these likely arose from the distinct hydrological regimes observed in each area. Groundwater from the western side of the Okatee headwaters was characterized by higher concentrations of dissolved organic and inorganic carbon, dissolved organic nitrogen, inorganic nutrients and reduced metabolites and trace gases, i.e. methane and nitrous oxide, than groundwater from the eastern side. Differences in microbial sulfate reduction, organic matter supply, and/or groundwater residence time likely contributed to this pattern. The contrasting features of the east and west sub-marsh zones highlight the need for multiple techniques for characterization of submarine groundwater discharge sources and the impact of biogeochemical processes on the delivery of nutrients and carbon to coastal areas via submarine groundwater discharge.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geochimica et Cosmochimica Acta","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.gca.2013.12.030","usgsCitation":"Porubsky, W., Weston, N., Moore, W., Ruppel, C., and Joye, S., 2014, Dynamics of submarine groundwater discharge and associated fluxes of dissolved nutrients, carbon, and trace gases to the coastal zone (Okatee River estuary, South Carolina): Geochimica et Cosmochimica Acta, v. 131, p. 81-97, https://doi.org/10.1016/j.gca.2013.12.030.","productDescription":"17 p.","startPage":"81","endPage":"97","numberOfPages":"17","ipdsId":"IP-051744","costCenters":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true},{"id":13634,"text":"South Atlantic Water Science Center","active":true,"usgs":true}],"links":[{"id":281785,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":281783,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.gca.2013.12.030"}],"country":"United States","state":"South Carolina","otherGeospatial":"Okatee River Estuary","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -80.95,32.26 ], [ -80.95,32.3 ], [ -80.9,32.3 ], [ -80.9,32.26 ], [ -80.95,32.26 ] ] ] } } ] }","volume":"131","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53517035e4b05569d805a1d1","contributors":{"authors":[{"text":"Porubsky, W.P.","contributorId":32000,"corporation":false,"usgs":true,"family":"Porubsky","given":"W.P.","email":"","affiliations":[],"preferred":false,"id":489686,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Weston, N.B.","contributorId":33221,"corporation":false,"usgs":true,"family":"Weston","given":"N.B.","email":"","affiliations":[],"preferred":false,"id":489687,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Moore, W.S.","contributorId":90875,"corporation":false,"usgs":true,"family":"Moore","given":"W.S.","email":"","affiliations":[],"preferred":false,"id":489689,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Ruppel, C.","contributorId":82050,"corporation":false,"usgs":true,"family":"Ruppel","given":"C.","email":"","affiliations":[],"preferred":false,"id":489688,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Joye, S.B.","contributorId":97266,"corporation":false,"usgs":true,"family":"Joye","given":"S.B.","email":"","affiliations":[],"preferred":false,"id":489690,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

The Mann-Kendall test was used to test for trends in annual and seasonal precipitation, annual and seasonal streamflows of 42 continuous-record USGS streamflow-gaging stations, annual pool elevations and releases from 16 USACE reservoirs, and annual releases from 11 dams on the Arkansas River. A statistically significant (p≤0.10) upward trend was observed in annual precipitation for the State, with a Sen slope of approximately 0.10 inch per year. Autumn and winter were the only seasons that had statistically significant trends in precipitation. Five of six physiographic sections and six of seven 4-digit hydrologic unit code (HUC) regions in Arkansas had statistically significant upward trends in autumn precipitation, with Sen slopes of approximately 0.06 to 0.10 inch per year. Sixteen sites had statistically significant upward trends in the annual mean daily streamflow and were located on streams that drained regions with statistically significant upward trends in annual precipitation. Expected annual rates of change corresponding to statistically significant trends in annual mean daily streamflows, which ranged from 0.32 to 0.88 percent, were greater than those corresponding to regions with statistically significant upward trends in annual precipitation, which ranged from 0.19 to 0.28 percent, suggesting that the observed trends in regional annual precipitation do not fully account for the observed trends in annual mean daily streamflows. Trends in annual maximum daily streamflows were similar to trends in the annual mean daily streamflows but were only statistically significant at seven sites. There were more statistically significant trends (28 of 42 sites) in the annual minimum daily streamflows than in the annual means or maximums. Statistically significant trends in the annual minimum daily streamflows were upward at 18 sites and downward at 10 sites. Despite autumn being the only season that had statistically significant upward trends in seasonal precipitation, statistically significant upward trends in seasonal mean streamflows occurred in every season but spring. Trends in the annual mean, maximum, and minimum daily pool elevations of USACE reservoirs were consistent between metrics for reservoirs in the White, Arkansas, and Ouachita River watersheds, while trends varied between metrics at DeQueen Lake, Millwood Lake, and Lake Chicot. Most of the statistically significant trends in pool elevation metrics were upward and gradual—Sen slopes were less than 0.37 foot per year—and were likely the result of changes in reservoir regulation plans. Trends in the annual mean and maximum daily releases from USACE reservoirs were generally upward in all HUC regions. There were few statistically significant trends in the annual mean daily releases because the reservoirs are operated to maintain a regulation stage at a downstream site according to guidelines set forth in the regulation plans of the reservoirs. The annual number of low-flow days was both increasing and decreasing for reservoirs in northern Arkansas and southern Missouri and generally increasing for reservoirs in southern Arkansas.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/sir20135240","collaboration":"Prepared in cooperation with the Arkansas Natural Resources Commission","usgsCitation":"Wagner, D.M., Krieger, J.D., and Merriman, K.R., 2014, Trends in precipitation, streamflow, reservoir pool elevations, and reservoir releases in Arkansas and selected sites in Louisiana, Missouri, and Oklahoma, 1951–2011: U.S. Geological Survey Scientific Investigations Report 2013-5240, vi, 61 p., https://doi.org/10.3133/sir20135240.","productDescription":"vi, 61 p.","numberOfPages":"67","onlineOnly":"Y","ipdsId":"IP-052791","costCenters":[{"id":129,"text":"Arkansas Water Science Center","active":true,"usgs":true}],"links":[{"id":281685,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/sir/2013/5240/"},{"id":281684,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/sir/2013/5240/pdf/sir2013-5240.pdf"},{"id":281686,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/sir20135240.jpg"}],"country":"United States","state":"Arkansas;Louisiana;Missouri;Oklahoma","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -96,8.333333333333334E-4 ], [ -96,8.333333333333334E-4 ], [ -90,8.333333333333334E-4 ], [ -90,8.333333333333334E-4 ], [ -96,8.333333333333334E-4 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd79a5e4b0b2908510cf57","contributors":{"authors":[{"text":"Wagner, Daniel M. 0000-0002-0432-450X dwagner@usgs.gov","orcid":"https://orcid.org/0000-0002-0432-450X","contributorId":4531,"corporation":false,"usgs":true,"family":"Wagner","given":"Daniel","email":"dwagner@usgs.gov","middleInitial":"M.","affiliations":[{"id":37778,"text":"WMA - Integrated Modeling and Prediction Division","active":true,"usgs":true},{"id":129,"text":"Arkansas Water Science Center","active":true,"usgs":true},{"id":24708,"text":"Lower Mississippi-Gulf Water Science Center","active":true,"usgs":true}],"preferred":true,"id":487841,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Krieger, Joshua D.","contributorId":43667,"corporation":false,"usgs":true,"family":"Krieger","given":"Joshua","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":487843,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Merriman, Katherine R. 0000-0002-1303-2410 kmerriman@usgs.gov","orcid":"https://orcid.org/0000-0002-1303-2410","contributorId":4973,"corporation":false,"usgs":true,"family":"Merriman","given":"Katherine","email":"kmerriman@usgs.gov","middleInitial":"R.","affiliations":[{"id":344,"text":"Illinois Water Science Center","active":true,"usgs":true}],"preferred":false,"id":487842,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}
