Background concentrations of Hg generally are &lt;0.01 &micro;g/L. The source of the Hg contamination has been hypothesized to arise from Hg of pesticide-application, atmospheric, and geologic origin being mobilized by some component(s) of septic-system effluent or urban leachates in unsewered residential areas. Initial results at many affected wells were not reproducible upon later resampling despite rigorous quality assurance, prompting concerns that duration of well flushing could affect the Hg concentrations. A cooperative study by the U.S. Geological Survey and the New Jersey Department of Environmental Protection examined variability in Hg results during the flushing of domestic wells. Samples were collected at regular intervals (about 10 minutes) during flushing for eight domestic wells, until stabilization criteria was met for field-measured parameters; the Hg concentrations in the final samples ranged from about 0.0005 to 11 &micro;g/L. Unfiltered Hg concentrations in samples collected during purging varied slightly, but particulate Hg concentration (unfiltered &ndash; filtered (0.45 micron capsule) concentration) typically was highly variable for each well, with no consistent pattern of increase or decrease in concentration. Surges of particulates probably were associated with pump cycling. Pre-pumping samples from the holding tanks generally had the lowest Hg concentrations among the samples collected at the well that day. Comparing the newly obtained results at each well to results from previous sampling indicated that Hg concentrations in water from the Hg-contaminated areas were generally greater among samples collected on different dates (long-term variations, months to years) than among samples collected on the same day (short-term variations, minutes to hours). The long-term variations likely are caused by changes in local pumping regimes and time-varying capture of slugs of Hg-contaminated water moving on flowpaths.</span></p>","largerWorkType":{"id":2,"text":"Article"},"conferenceTitle":"Northeastern Section (45th Annual) and Southeastern Section (59th Annual) Joint Meeting","conferenceDate":"March 16, 2010","conferenceLocation":"Baltimore, MD","language":"English","publisher":"Geological Society of America","publisherLocation":"Boulder, CO","usgsCitation":"Szabo, Z., Barringer, J., Jacobsen, E., Smith, N.P., Gallagher, R.A., and Sites, A., 2010, Variability of mercury concentrations in domestic well water, New Jersey Coastal Plain, Northeastern Section (45th Annual) and Southeastern Section (59th Annual) Joint Meeting, v. 42, no. 1, Baltimore, MD, March 16, 2010, p. 178-178.","productDescription":"1 p.","startPage":"178","endPage":"178","numberOfPages":"1","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-030466","costCenters":[{"id":470,"text":"New Jersey Water Science Center","active":true,"usgs":true}],"links":[{"id":307538,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":306548,"rank":1,"type":{"id":15,"text":"Index Page"},"url":"https://gsa.confex.com/gsa/2010NE/finalprogram/abstract_169976.htm","linkFileType":{"id":5,"text":"html"}}],"country":"UNITED STATES","state":"New Jersey","otherGeospatial":"Kirkwood-Cohansey aquifer system","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -74.8553466796875,\n              38.91240739487225\n            ],\n            [\n              -74.63012695312499,\n              39.16414104768742\n            ],\n            [\n              -74.29504394531249,\n              39.436192999314066\n            ],\n            [\n              -74.0423583984375,\n              39.829631721333726\n            ],\n            [\n              -73.9544677734375,\n              40.23760536584024\n            ],\n            [\n              -73.93798828125,\n              40.421860362045194\n            ],\n            [\n              -74.234619140625,\n              40.50544628405211\n            ],\n            [\n              -74.4378662109375,\n              40.52215098562377\n            ],\n            [\n              -74.937744140625,\n              40.153686857794035\n            ],\n            [\n              -75.56396484375,\n              39.70296052957233\n            ],\n            [\n              -75.65185546874999,\n              39.55064761909318\n            ],\n            [\n              -74.99267578125,\n              38.92095542046727\n            ],\n            [\n              -74.8828125,\n              38.90813299596705\n            ],\n            [\n              -74.8553466796875,\n              38.91240739487225\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"42","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"55dee337e4b0518e354e082d","contributors":{"authors":[{"text":"Szabo, Zoltan 0000-0002-0760-9607 zszabo@usgs.gov","orcid":"https://orcid.org/0000-0002-0760-9607","contributorId":2240,"corporation":false,"usgs":true,"family":"Szabo","given":"Zoltan","email":"zszabo@usgs.gov","affiliations":[{"id":451,"text":"National Water Quality Assessment Program","active":true,"usgs":true}],"preferred":false,"id":567670,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Barringer, Julia L.","contributorId":59419,"corporation":false,"usgs":true,"family":"Barringer","given":"Julia L.","affiliations":[],"preferred":false,"id":567671,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Jacobsen, Eric jacobsen@usgs.gov","contributorId":3864,"corporation":false,"usgs":true,"family":"Jacobsen","given":"Eric","email":"jacobsen@usgs.gov","affiliations":[],"preferred":true,"id":567672,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Smith, Nicholas P","contributorId":146386,"corporation":false,"usgs":true,"family":"Smith","given":"Nicholas","email":"","middleInitial":"P","affiliations":[{"id":470,"text":"New Jersey Water Science Center","active":true,"usgs":true}],"preferred":false,"id":567673,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Gallagher, Robert A","contributorId":118171,"corporation":false,"usgs":true,"family":"Gallagher","given":"Robert","email":"","middleInitial":"A","affiliations":[],"preferred":false,"id":513249,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Sites, Andrew","contributorId":117822,"corporation":false,"usgs":true,"family":"Sites","given":"Andrew","email":"","affiliations":[],"preferred":false,"id":513248,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Upper Klamath Lake, Oregon, and its tributaries are considered the most critical remaining habitat for these two species. Age-0 suckers are often abundant in Upper Klamath Lake throughout the summer months, but catches decline dramatically between late August and early September each year and age-1 and older sub-adult suckers are rare. These rapid declines in catch rates and a lack of substantial recruitment into adult sucker populations in recent years suggests sucker populations experience high mortality between their first summer and first spawn. A lack of access to, or abundance of, optimal rearing habitat may exacerbate juvenile sucker mortality or restrict juvenile growth or development. \r\n\r\nSummer age-0 sucker habitat use and distribution has been studied extensively, but many uncertainties remain about age-1 and older juvenile habitat use, distribution, and movement patterns within Upper Klamath Lake. We designed a study to examine seasonal changes in distribution of age-1 suckers in Upper Klamath Lake as they relate to depth and water quality. In this document, which meets our annual data summary and reporting obligations, we discuss the results of our second annual spring and summer sampling effort. \r\n\r\nCatch data collected in 2007 and 2008 indicate seasonal changes in age-1 and older juvenile sucker habitat use coincident with changes in water quality, which were previously undocumented. In both years during April and May, age-1 and older juvenile suckers were found in shallow water environments. Then, as water temperatures began to warm throughout Upper Klamath Lake in June, age-1 and older juvenile suckers primarily were captured along the western shore in some of the deepest available environments. Following a dramatic decrease in dissolved oxygen concentrations in Eagle Ridge Trench, juvenile suckers were no longer found along the western shore but were captured throughout the rest of Upper Klamath Lake. When dissolved oxygen concentrations were 4 milligrams per liter or greater along the western shore, juvenile sucker captures were again concentrated in that area. Although this pattern indicates that low dissolved oxygen concentration or another related water-quality limitation may force juvenile suckers to leave the western shore, it is unclear as to why age-1 and older juveniles might be attracted to the area in the first place. Understanding this apparent behavior could be important to managing habitat for these species. \r\n\r\nIn this data summary, we also describe the distribution of catches of age-0 suckers and other fishes in Upper Klamath Lake. These data corroborate previous studies that describe age-0 sucker habitat as shallow relative to depths available in Upper Klamath Lake. In this study, we did not seek, nor find additional clarification on age-0 sucker habitat use and distribution in Upper Klamath Lake. Our brief description of the distribution and abundance of all other fish species caught provides a context in which to assess the rarity of juvenile suckers within the fish community of Upper Klamath Lake. \r\n","language":"ENGLISH","publisher":"U.S. Geological Survey","doi":"10.3133/ofr20101051","usgsCitation":"Burdick, S.M., and VanderKooi, S., 2010, Temporal and Spatial Distribution of Endangered Juvenile Lost River and Shortnose Suckers in Relation to Environmental Variables in Upper Klamath Lake, Oregon: 2008 Annual Data Summary : U.S. Geological Survey Open-File Report 2010-1051, vi, 36 p. , https://doi.org/10.3133/ofr20101051.","productDescription":"vi, 36 p.

After World War II, better metallurgical management practices and environmental regulations reduced mercury contamination, but total mercury concentrations in surface sediment of Sinclair Inlet have decreased slowly because of the low rate of sedimentation relative to the vertical mixing within sediment. The slopes of linear regressions between the total mercury and total organic carbon concentrations of sediment offshore of Puget Sound urban areas was the best indicator of general mercury contamination above pre-industrial levels. Prior to the 2000-01 remediation, this indicator placed Sinclair Inlet in the tier of estuaries with the highest level of mercury contamination, along with Bellingham Bay in northern Puget Sound and Elliott Bay near Seattle. This indicator also suggests that the 2000/2001 remediation dredging had significant positive effect on Sinclair Inlet as a whole. In 2007, about 80 percent of the area of the Bremerton naval complex had sediment total mercury concentrations within about 0.5 milligrams per kilogram of the Sinclair Inlet regression. Three areas adjacent to the waterfront of the Bremerton naval complex have total mercury concentrations above this range and indicate a possible terrestrial source from waterfront areas of Bremerton naval complex. Total mercury concentrations in unfiltered Sinclair Inlet marine waters are about three times higher than those of central Puget Sound, but the small numbers of samples and complex physical and geochemical processes make it difficult to interpret the geographical distribution of mercury in marine waters from Sinclair Inlet.\r\n\r\nTotal mercury concentrations in various biota species were compared among geographical locations and included data of composite samples, individual specimens, and caged mussels. Total mercury concentrations in muscle and liver of English sole from Sinclair Inlet ranked in the upper quarter and third, respectively, of Puget Sound locations. For other species, concentrations from Sinclair Inlet were within the mid-range of locations (for example, Chinook salmon). Total mercury concentrations of the long-lived and higher trophic rockfish in composites and individual specimens from Sinclair Inlet tended to be the highest in Puget Sound. For a given size, sand sole, graceful crab, staghorn sculpin, surf perch, and sea cucumber individuals collected from Sinclair Inlet had higher total mercury concentrations than individuals collected from non-urban estuaries. Total mercury concentrations in individual English sole and ratfish were not significantly different than in individuals of various sizes collected from either urban or non-urban estuaries in Puget Sound. Total mercury concentrations in English sole collected from Sinclair Inlet after the 2000-2001 dredging appear to have lower total mercury concentrations than those collected before (1996) the dredging project. The highest total mercury concentrations of mussels caged in 2002 were not within the Bremerton naval complex, but within the Port Orchard Marina and inner Sinclair Inlet.\r\n","language":"ENGLISH","publisher":"U.S. Geological Survey","doi":"10.3133/ofr20091285","usgsCitation":"Paulson, A.J., Keys, M.E., and Scholting, K.L., 2010, Mercury in Sediment, Water, and Biota of Sinclair Inlet, Puget Sound, Washington, 1989-2007: U.S. Geological Survey Open-File Report 2009-1285, xii, 220 p., https://doi.org/10.3133/ofr20091285.","productDescription":"xii, 220 p.","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":622,"text":"Washington Water Science Center","active":true,"usgs":true}],"links":[{"id":125368,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr_2009_1285.jpg"},{"id":13515,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2009/1285/","linkFileType":{"id":5,"text":"html"}}],"geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -122.83333333333333,47.5 ], [ -122.83333333333333,47.78333333333333 ], [ -122.5,47.78333333333333 ], [ -122.5,47.5 ], [ -122.83333333333333,47.5 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a2ce4b07f02db6140b0","contributors":{"authors":[{"text":"Paulson, Anthony J. 0000-0002-2358-8834 apaulson@usgs.gov","orcid":"https://orcid.org/0000-0002-2358-8834","contributorId":5236,"corporation":false,"usgs":true,"family":"Paulson","given":"Anthony","email":"apaulson@usgs.gov","middleInitial":"J.","affiliations":[],"preferred":true,"id":304842,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Keys, Morgan E.","contributorId":92776,"corporation":false,"usgs":true,"family":"Keys","given":"Morgan","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":304844,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Scholting, Kelly L.","contributorId":17723,"corporation":false,"usgs":true,"family":"Scholting","given":"Kelly","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":304843,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

It was specifically concerned with the depth range of 30–100 m, where more than 186,000 km2 of potential seafloor area was identified within the US Gulf of Mexico/Florida, Caribbean, and main Hawaiian Islands. The geomorphology of MCEs was largely inherited from a variety of pre-existing structures of highly diverse origins, which, in combination with environmental stress and physical controls, restrict the distribution of MCEs. Sea-level history, along with depositional and erosional processes, played an integral role in formation of MCE settings. However, mapping the distribution of both potential MCE topography/substrate and existing MCE habitat is only beginning. Mapping techniques pertinent to understanding morphology and MCE distributions are discussed throughout this paper. Future investigations need to consider more cost-effective and remote methods (such as autonomous underwater vehicles (AUVs) and acoustics) in order to assess the distribution and extent of MCE habitat. Some understanding of the history of known MCEs through coring studies would help understand their initiation and response to environmental change over time, essential for assessing how they may be impacted by future environmental change.</p>","language":"English","publisher":"Springer","doi":"10.1007/s00338-010-0613-6","usgsCitation":"Locker, S., Armstrong, R.A., Battista, T.A., Rooney, J.,

High-flow experiments (HFE) that mimic one aspect of the natural hydrograph (floods) were implemented in 1996, 2004, and 2008. The primary goal of these experiments was to increase the size and total area of sandbar habitats that provide both camping sites for recreational users and create backwaters (areas of stagnant flow in the lee of return-current eddies) that may be important as rearing habitat for native fish. Experimental flows might also positively or negatively alter the rainbow trout (Oncorhynchus mykiss) sport fishery in the clear tailwater reach below Glen Canyon Dam, Ariz., and native fish populations in downstream reaches (for example, endangered humpback chub, Gila cypha) through changes in available food resources. \r\n\r\nWe examined the short-term response of benthic macroinvertebrates to the March 2008 HFE at three sites [river mile 0 (RM 0, 15.7 miles downriver from the dam), RM 62, and RM 225] along the Colorado River downstream from Glen Canyon Dam by sampling immediately before and then 1, 7, 14, and 30 days after the HFE. We selected these sites because of their importance to management; RM 0 has a valuable trout fishery, and RM 62 is the location of the largest population of the endangered humpback chub in the Grand Canyon. In addition to the short-term collection of samples, as part of parallel investigations, we collected 3 years of monthly (quarterly for RM 62) benthic macroinvertebrate samples that included 15 months of post-HFE data for all three sites, but processing of the samples is only complete for one site (RM 0). At RM 0, the HFE caused an immediate 1.75 g AFDM/m2 (expressed as grams ash-free dry mass, or AFDM) reduction of macroinvertebrate biomass that was driven by significant reductions in the biomass of the two dominant taxa in this reach-Potamopyrgus antipodarum (New Zealand mud snails) and Gammarus lacustris (scuds or side-swimmers)-and also biomass reductions of other common taxa (worms in the families Lumbricidae and Tubificidae). Invertebrate drift estimates during the HFE suggest that reductions in biomass of some taxa were because of export from the reach. Reductions in biomass of P. antipodarum and G. lacustris persisted at least 15 months after the HFE, when this study concluded, and coincided with a significant decline in the annual production of these taxa: P. antipodarum production of 11 to 13 g AFDM/m2/yr in two pre-HFE years versus 2 g AFDM/m2/yr in the post-HFE year, and G. lacustris production of 7 to 8 g AFDM/m2/yr in two pre-HFE years versus 3 g AFDM/m2/yr in the post-HFE year. There were not changes in invertebrate feeding habits in response to the HFE, as our 3-year dataset of invertebrate diets indicated no substantial changes. Our long-term analysis of the composition of the drift indicates that because of a reduction in P. antipodarum in the drift relative to digestible taxa, the quality of the drift as a food resource for fishes increased. At downstream sites, total assemblage biomass did not decline, likely because assemblages were dominated by blackflies (Simulium arcticum), which were not affected by the HFE. Similar to RM 0, G. lacustris and Tubificidae had significantly lower biomass after the HFE at RM 62 and RM 225. Chironomids were also significantly lower following the flood at both downstream sites. \r\n\r\nOur findings demonstrate that the effects of a HFE on invertebrates may persist up to at least 15 months in the clear tailwater below the dam, whereas in downstream reaches impacts were more short lived. If controlling the abundance of P. antipodarum is a goal of managers, our findings indicate that periodic HFEs on the order of every 2 to 3 years may be an effective strategy for meeting that goal. More frequent HFEs may cause a shift in the state of the benthic invertebrate assemblage of the tailwa","language":"ENGLISH","publisher":"U.S. Geological Survey","doi":"10.3133/ofr20101031","collaboration":"In cooperation with Cary Institute for Ecosystem Studies, Montana State University, Loyola University-Chicago, University of Wyoming, and Idaho State University","usgsCitation":"Rosi-Marshall, E.J., Kennedy, T., Kincaid, D., Cross, W.F., Kelly, H.A., Behn, K., White, T., Hall, R., and Baxter, C., 2010, Short-Term Effects of the 2008 High-Flow Experiment on Macroinvertebrates in Colorado River Below Glen Canyon Dam, Arizona: U.S. Geological Survey Open-File Report 2010-1031, iv, 28 p., https://doi.org/10.3133/ofr20101031.","productDescription":"iv, 28 p.","onlineOnly":"Y","additionalOnlineFiles":"N","costCenters":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"links":[{"id":125366,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr_2010_1031.jpg"},{"id":13507,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2010/1031/","linkFileType":{"id":5,"text":"html"}}],"scale":"1500000","projection":"Stateplane, Arizona Central Zone","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -114.83333333333333,35 ], [ -114.83333333333333,37.833333333333336 ], [ -110.83333333333333,37.833333333333336 ], [ -110.83333333333333,35 ], [ -114.83333333333333,35 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49fae4b07f02db5f3f0b","contributors":{"authors":[{"text":"Rosi-Marshall, Emma J.","contributorId":17722,"corporation":false,"usgs":true,"family":"Rosi-Marshall","given":"Emma","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":304816,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kennedy, Theodore A. 0000-0003-3477-3629","orcid":"https://orcid.org/0000-0003-3477-3629","contributorId":50227,"corporation":false,"usgs":true,"family":"Kennedy","given":"Theodore A.","affiliations":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"preferred":true,"id":304821,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kincaid, Dustin W.","contributorId":100970,"corporation":false,"usgs":true,"family":"Kincaid","given":"Dustin W.","affiliations":[],"preferred":false,"id":304823,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Cross, Wyatt F.","contributorId":70881,"corporation":false,"usgs":true,"family":"Cross","given":"Wyatt","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":304822,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Kelly, Holly A.W.","contributorId":27971,"corporation":false,"usgs":true,"family":"Kelly","given":"Holly","email":"","middleInitial":"A.W.","affiliations":[],"preferred":false,"id":304819,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Behn, Kathrine A.","contributorId":26784,"corporation":false,"usgs":true,"family":"Behn","given":"Kathrine A.","affiliations":[],"preferred":false,"id":304818,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"White, Tyler","contributorId":24886,"corporation":false,"usgs":true,"family":"White","given":"Tyler","email":"","affiliations":[],"preferred":false,"id":304817,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Hall, Robert O.

These experimental flows also have the potential to affect the rainbow trout (Oncorhynchus mykiss) population in the Lees Ferry tailwater reach immediately below the dam, which supports a highly valued recreational fishery and likely influences the abundance of rainbow trout in Grand Canyon. Understanding how flow regimes affect the survival and growth of juvenile rainbow trout is critical to interpreting trends in adult abundance. This study reports on the effects of HFEs in 2004 and 2008 on early life stages of rainbow trout in the Lees Ferry reach on the basis of monthly sampling of redds (egg nests) and the abundance of the age-0 trout (fertilization to about 1 to 2 months from emergence) and their growth during a 7-year period between 2003 and 2009. \r\n\r\nMultiple lines of evidence indicate that the March 2008 HFE resulted in a large increase in early survival rates of age-0 trout because of an improvement in habitat conditions. A stock-recruitment analysis demonstrated that age-0 abundance in July 2008 was more than fourfold higher than expected, given the number of viable eggs that produced these fish. A hatch-date analysis showed that early survival rates were much higher for cohorts that hatched about 1 month after the 2008 HFE (about April 15, 2008) relative to those fish that hatched before this date. These cohorts, fertilized after the 2008 HFE, would have emerged into a benthic invertebrate community that had recovered, and was possibly enhanced by, the HFE. Interannual differences in growth of age-0 trout, determined on the basis of otolith microstructure, support this hypothesis. Growth rates in the summer and fall of 2008 (0.44 mm/day) were virtually the same as in 2006 (0.46 mm/day), the highest recorded during 6 years, even though abundance was eightfold greater in 2008. We speculate that the 60-hour-long 2008 HFE (with peak magnitude about twice that of the annual peak flow during the previous 4 years) increased interstitial spaces in the gravel bed substrate and food availability or quality, leading to higher early survival of recently emerged trout and better growth of these fish through summer and fall. Abundance in 2009 was more than twofold higher than expected, given the estimated number of viable eggs deposited in that year, perhaps indicating that the effect of the 2008 HFE on early life stages was somewhat persistent. \r\n\r\nIn a 3-week interval that spanned the November 2004 HFE, abundance of age-0 trout that were approximately 7 months old from hatch experienced about a threefold decline, compared to the approximately twofold decrease observed between November and December 2008. Abundance of age-0 trout that were approximately 10 months old from hatch was very similar across sampling trips that spanned the March 2008 HFE. It is uncertain whether the decline in abundance after the November 2004 HFE was the result of higher flow-induced mortality or higher flow-induced downstream dispersal. A focused monitoring effort in Marble Canyon (the reach immediately downstream of the Lees Ferry tailwater) before and after future HFEs is recommended to resolve this uncertainty. Relatively detailed monitoring of early life stages-such as the program described in this study-is essential to establish linkages between Glen Canyon Dam operations, or possibly other factors, and trends in the abundance of important nonnative and native fish populations living downstream within Grand Canyon National Park. \r\n","language":"ENGLISH","publisher":"U.S. Geological Survey","doi":"10.3133/ofr20101034","collaboration":"Prepared in cooperation with Ecometric Research, Inc., and Northern Arizona University","usgsCitation":"Korman, J., Kaplinski, M., and Melis, T., 2010, Effects of High-Flow Experiments from Glen Canyon Dam on Abundance, Growth, and Survival Rates of Early Life Stages of Rainbow Trout in the Lees Ferry Reach of the Colorado River: U.S. Geological Survey Open-File Report 2010-1034, iv, 31 p. , https://doi.org/10.3133/ofr20101034.","productDescription":"iv, 31 p.

Faults were previously thought to relieve stress either through continuous aseismic sliding, or as earthquakes resulting from instantaneous failure of locked faults. In contrast, slow-slip events proceed so slowly that slip is limited and only low-frequency (or no) seismic waves radiate. We find that slow-slip phenomena are not unique to the depths (tens of kilometres) of subduction zone plate interfaces. They occur on faults in many settings, at numerous scales and owing to various loading processes, including landslides and glaciers. Taken together, the observations indicate that slowly slipping fault surfaces relax most of the accrued stresses through aseismic slip. Aseismic motion can trigger more rapid slip elsewhere on the fault that is sufficiently fast to generate seismic waves. The resulting radiation has characteristics ranging from those indicative of slow but seismic slip, to those typical of earthquakes. The mode of seismic slip depends on the inherent characteristics of the fault, such as the frictional properties. Slow-slip events have previously been classified as a distinct mode of fault slip compared with that seen in earthquakes. We conclude that instead, slip modes span a continuum and are of common occurrence.","language":"English","publisher":"Nature Publishing Group","doi":"10.1038/ngeo940","usgsCitation":"Peng, Z., and Gomberg, J., 2010, An integrated perspective of the continuum between earthquakes and slow-slip phenomena: Nature Geoscience, v. 3, p. 599-607, https://doi.org/10.1038/ngeo940.","productDescription":"9 p.","startPage":"599","endPage":"607","numberOfPages":"9","ipdsId":"IP-020384","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":272173,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"3","noUsgsAuthors":false,"publicationDate":"2010-08-22","publicationStatus":"PW","scienceBaseUri":"518e16dfe4b05ebc8f7cc2e2","contributors":{"authors":[{"text":"Peng, Zhigang","contributorId":69432,"corporation":false,"usgs":true,"family":"Peng","given":"Zhigang","affiliations":[],"preferred":false,"id":473660,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Gomberg, Joan","contributorId":77919,"corporation":false,"usgs":true,"family":"Gomberg","given":"Joan","affiliations":[],"preferred":false,"id":473661,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The proposal calls for the landfill to receive by rail about 20,000 tons of waste per week for up to 50 years. On September 22, 2009, the Interior Appropriation (S.A. 2494) was amended to require the U.S. Geological Survey to evaluate the proposed Jungo landfill site for: (1) potential water-quality impacts on nearby surface-water resources, including Rye Patch Reservoir and the Humboldt River; (2) potential impacts on municipal water resources of Winnemucca, Nevada; (3) locations and altitudes of aquifers; (4) how long it will take waste seepage from the site to contaminate local aquifers; and (5) the direction and distance that contaminated groundwater would travel at 95 and 190 years. This evaluation was based on review of existing data and information.\r\n\r\nDesert Valley is tributary to the Black Rock Desert via the Quinn River in northern Desert Valley. The Humboldt River and Rye Patch Reservoir would not be affected by surface releases from the proposed Jungo landfill site because they are in the Humboldt basin. Winnemucca, on the Humboldt River, is 30 miles east of the Jungo landfill site and in the Humboldt basin. Groundwater-flow directions indicate that subsurface flow near the proposed Jungo landfill site is toward the south-southwest. Therefore, municipal water resources of Winnemucca would not be affected by surface or subsurface releases from the proposed Jungo landfill site.\r\n\r\nBasin-fill aquifers underlie the 680-square-mile valley floor in Desert Valley. Altitudes around the proposed Jungo landfill site range from 4,162 to 4,175 feet. Depth to groundwater is fairly shallow in southern Desert Valley and is about 60 feet below land surface at the proposed Jungo landfill site. A groundwater divide exists about 7 miles north of the proposed Jungo landfill site. Groundwater north of the divide flows north towards the Quinn River. South of the divide and near the proposed Jungo landfill site, groundwater flows in a south-southwesterly direction. Data are insufficient to determine whether groundwater eventually flows into Rye Patch Reservoir or other adjacent valleys. Estimates indicate that contaminants would travel about 0.02 mile and a maximum of 2.5 miles in 95 years and about 0.04 mile and a maximum of 5.0 miles in 190 years.

These data are discussed in the context of geologic observations at the site, the details of which are provided in a separate report. This integrated approach uses the geologic observations to help constrain subsurface information obtained from the analysis of surface geophysical measurements, which is a critical step toward using the geophysical data in a meaningful hydrogeologic framework. This approach combines the benefit of many direct but sparse field observations with spatially continuous but indirect measurements of physical properties through the use of geophysics. Surface geophysical data include: (1) electrical resistivity profiles aimed at imaging variability in subsurface structures and fluid content; (2) self-potentials, which are sensitive to mineralized zones at this site and, to a lesser extent, shallow-flow patterns; and (3) magnetic measurements, which provide information on lateral variability in near-surface geologic features, although there are few magnetic minerals in the rocks at this site.\r\n\r\nResults from the resistivity data indicate a general two-layer model in which an upper highly resistive unit, 3 to 10 meters thick, overlies a less resistive unit that is imaged to depths of 20 to 25 meters. The high resistivity of the upper unit likely is attributed to unsaturated conditions, meaning that the contact between the upper and lower units may correspond to the water table. Significant lateral heterogeneity is observed because of the presence of major features such as the Standard and Elk fault veins, as well as highly heterogeneous joint distributions. Very high resistivities (greater than 10 kiloohmmeters) are observed in locations that may correspond to more silicified, lower porosity rock. Several thin (2 to 3 meters deep and up to tens of meters wide) low-resistivity features in the very near surface coincide with observed surface-water drainage features at the site. These are limited to depths less than 3 meters and may indicate surface and very shallow groundwater flowing downhill on top of less permeable bedrock. The data do not clearly point to discrete zones of high infiltration, but these cannot be ruled out given the heterogeneous nature of joints in the shallow subsurface. Disseminated and localized electrically conductive mineralization do not appear to play a strong role in controlling the resistivity values, which generally are high throughout the site. \r\n\r\nThe self-potential analysis highlights the Standard fault vein, the northwest (NW) Elk vein near the Elk portal, and several polymetallic quartz veins. These features contain sulfide minerals in the subsurface that form an electrochemical cell that produces their distinct self-potential signal. A smaller component of the self-potential signal is attributed to relatively moderate topographically driven shallow groundwater flow, which is most prevalent in the vicinity of Elk Creek and to a lesser extent in the area of surface-water drainage below the Level 5 portal. Given the anomalies associated with the electrochemical weathering near the Standard fault vein, it is not possible to completely rule out downward infiltration of surface water and shallow groundwater intersected by the fault, though this is an unlikely scenario given the available data.\r\n\r\nMagnetic data show little variation, consistent with the mostly nonmagnetic host rocks and mineralization at the site, which is verified by magnetic susceptibility measurements and X-ray diffraction mineralogy data on local rock samples. The contact between the Ohio Creek Member of the Mesaverde Formation and Wasatch Formation coincides with a change in character of the magnetic signature, though","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr20091284","collaboration":"Prepared in cooperation with the U.S. Environmental Protection Agency","usgsCitation":"Minsley, B.J., Ball, L.B., Burton, B., Caine, J.S., Curry-Elrod, E., and Manning, A.H., 2010, Geophysical characterization of subsurface properties relevant to the hydrology of the Standard Mine in Elk Basin, Colorado: U.S. Geological Survey Open-File Report 2009-1284, vi, 41 p., https://doi.org/10.3133/ofr20091284.","productDescription":"vi, 41 p.","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":212,"text":"Crustal Imaging and Characterization","active":false,"usgs":true}],"links":[{"id":125798,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/Ofr_2009_1284.jpg"},{"id":402901,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_92030.htm","linkFileType":{"id":5,"text":"html"}},{"id":13506,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2009/1284/","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Colorado","otherGeospatial":"Elk Basin, Standard Mine","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -107.0758,\n              38.8294\n            ],\n            [\n              -107.0656,\n              38.8294\n            ],\n            [\n              -107.0656,\n              38.8372\n            ],\n            [\n              -107.0758,\n              38.8372\n            ],\n            [\n              -107.0758,\n              38.8294\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ac9e4b07f02db67c4cf","contributors":{"authors":[{"text":"Minsley, Burke J. 0000-0003-1689-1306 bminsley@usgs.gov","orcid":"https://orcid.org/0000-0003-1689-1306","contributorId":697,"corporation":false,"usgs":true,"family":"Minsley","given":"Burke","email":"bminsley@usgs.gov","middleInitial":"J.","affiliations":[{"id":211,"text":"Crustal Geophysics and Geochemistry Science Center","active":true,"usgs":true}],"preferred":true,"id":304810,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Ball, Lyndsay B. 0000-0002-6356-4693 lbball@usgs.gov","orcid":"https://orcid.org/0000-0002-6356-4693","contributorId":1138,"corporation":false,"usgs":true,"family":"Ball","given":"Lyndsay","email":"lbball@usgs.gov","middleInitial":"B.","affiliations":[{"id":211,"text":"Crustal Geophysics and Geochemistry Science Center","active":true,"usgs":true}],"preferred":true,"id":304811,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Burton, Bethany L. 0000-0001-5011-7862 blburton@usgs.gov","orcid":"https://orcid.org/0000-0001-5011-7862","contributorId":1341,"corporation":false,"usgs":true,"family":"Burton","given":"Bethany L.","email":"blburton@usgs.gov","affiliations":[{"id":35995,"text":"Geology, Geophysics, and Geochemistry Science Center","active":true,"usgs":true}],"preferred":false,"id":304813,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Caine, Jonathan S. 0000-0002-7269-6989 jscaine@usgs.gov","orcid":"https://orcid.org/0000-0002-7269-6989","contributorId":1272,"corporation":false,"usgs":true,"family":"Caine","given":"Jonathan","email":"jscaine@usgs.gov","middleInitial":"S.","affiliations":[{"id":211,"text":"Crustal Geophysics and Geochemistry Science Center","active":true,"usgs":true}],"preferred":false,"id":304814,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Curry-Elrod, Erika","contributorId":83634,"corporation":false,"usgs":true,"family":"Curry-Elrod","given":"Erika","email":"","affiliations":[],"preferred":false,"id":304815,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Manning, Andrew H. 0000-0002-6404-1237 amanning@usgs.gov","orcid":"https://orcid.org/0000-0002-6404-1237","contributorId":1305,"corporation":false,"usgs":true,"family":"Manning","given":"Andrew","email":"amanning@usgs.gov","middleInitial":"H.","affiliations":[{"id":171,"text":"Central Mineral and Environmental Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":304812,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

These sites recorded the M8.0 2003 Tokachi-Oki earthquake, with recorded accelerations above 0.4 g at both sites as well as numerous ground motions from smaller events. Weak ground motions indicate that site TKCH08 is well modeled with the assumption of plane SH waves traveling through a 1D medium (SH1D), while TKCH05 is characteristic of a poor fit to the SH1D theoretical response. We hypothesized that the misfit at TKCH05results from the heterogeneity of the subsurface. To test this hypothesis, we measured four S-wave velocity profiles in the vicinity (&lt; 300 m) of each site with the spectral analysis of surface waves (SASW) method. This KiK-net site pair is ideal for assessing the relative importance of 3D site effects and nonlinear site effects. The linear ground motions at TKCH05 isolate the 3D site effects, as we hypothesized from the linear ground motions and confirmed with our subsequent SASW surveys. The Tokachi-Oki time history at TKCH08 isolates the effects of nonlinearity from spatial heterogeneity because the 3D effects are negligible. The Tokachi-Oki time history at TKCH05 includes both nonlinear and 3D site effects. Comparisons of the accuracy of the SH1D model predictions of these surface time histories from the downhole time histories indicates that the 3D site effects are at least as important as nonlinear effects in this case. The errors associated with the assumption of a 1D medium and 1D wave propagation will be carried into a nonlinear analysis that relies on these same assumptions. Thus, the presence of 3D effects should be ruled out prior to a 1D nonlinear analysis. The SH1D residuals show that 3D effects can be mistaken for nonlinear effects.</span></p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Joint conference proceedings: 7th international conference on urban earthquake engineering (7CUEE), 5th international conference on earthquake engineering (5ICEE)","largerWorkSubtype":{"id":12,"text":"Conference publication"},"conferenceTitle":"7th International Conference on Urban Earthquake Engineering (7CUEE) & 5th International Conference on Earthquake Engineering (5ICEE)","conferenceDate":"March 3-5, 2010","conferenceLocation":"Tokyo, Japan","language":"English","publisher":"Center for Urban Earthquake Engineering","usgsCitation":"Thompson, E., Tanaka, Y., Baise, L.G., and Kayen, R., 2010, Three-dimensional site response at KiK-net downhole arrays, <i>in</i> Joint conference proceedings: 7th international conference on urban earthquake engineering (7CUEE), 5th international conference on earthquake engineering (5ICEE), Tokyo, Japan, March 3-5, 2010, 9 p.","productDescription":"9 p.","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-018649","costCenters":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":307976,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Japan","otherGeospatial":"Hokkaido","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              142.767333984375,\n              43.78695837311561\n            ],\n            [\n              143.690185546875,\n              43.78695837311561\n            ],\n            [\n              143.690185546875,\n              44.59829048984011\n            ],\n            [\n              142.767333984375,\n              44.59829048984011\n            ],\n            [\n              142.767333984375,\n              43.78695837311561\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"55f006aee4b0dacf699ea004","contributors":{"authors":[{"text":"Thompson, Eric M.","contributorId":48501,"corporation":false,"usgs":true,"family":"Thompson","given":"Eric M.","affiliations":[],"preferred":false,"id":571749,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Tanaka, Yasuo","contributorId":86866,"corporation":false,"usgs":true,"family":"Tanaka","given":"Yasuo","affiliations":[],"preferred":false,"id":571750,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Baise, Laurie G.","contributorId":52859,"corporation":false,"usgs":true,"family":"Baise","given":"Laurie","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":571751,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Kayen, Robert E. rkayen@usgs.gov","contributorId":2787,"corporation":false,"usgs":true,"family":"Kayen","given":"Robert E.","email":"rkayen@usgs.gov","affiliations":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":false,"id":571752,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

The effect of urbanization on stream macroinvertebrate communities was measured across a gradient of basins in each of nine metropolitan regions across the conterminous United States. The hierarchical nature of this dataset was harnessed in a multi-tiered model structure, predicting both invertebrate response at the basin scale and differences in invertebrate response at the region scale. Ordination site scores, total taxa richness, Ephemeroptera, Plecoptera, Trichoptera (EPT) taxa richness, and richness-weighted mean tolerance of organisms at a site were used to describe invertebrate responses. Percentage of urban land cover was used as a basin-level predictor variable. Regional mean precipitation, air temperature, and antecedent agriculture were used as region-level predictor variables. Multilevel hierarchical models were fit to both levels of data simultaneously, borrowing statistical strength from the complete dataset to reduce uncertainty in regional coefficient estimates. Additionally, whereas non-hierarchical regressions were only able to show differing relations between invertebrate responses and urban intensity separately for each region, the multilevel hierarchical regressions were able to explain and quantify those differences within a single model. In this way, this modeling approach directly establishes the importance of antecedent agricultural conditions in masking the response of invertebrates to urbanization in metropolitan regions such as Milwaukee-Green Bay, Wisconsin; Denver, Colorado; and Dallas-Fort Worth, Texas. Also, these models show that regions with high precipitation, such as Atlanta, Georgia; Birmingham, Alabama; and Portland, Oregon, start out with better regional background conditions of invertebrates prior to urbanization but experience faster negative rates of change with urbanization. Ultimately, this urbanization-invertebrate response example is used to detail the multilevel hierarchical construction methodology, showing how the result is a set of models that are both statistically more rigorous and ecologically more interpretable than simple linear regression models.\r\n","language":"ENGLISH","publisher":"U.S. Geological Survey","doi":"10.3133/sir20095243","collaboration":"National Water-Quality Assessment Program","usgsCitation":"Kashuba, R., Cha, Y., Alameddine, I., Lee, B., and Cuffney, T.F., 2010, Multilevel Hierarchical Modeling of Benthic Macroinvertebrate Responses to Urbanization in Nine Metropolitan Regions across the Conterminous United States: U.S. Geological Survey Scientific Investigations Report 2009-5243, xi, 88p., https://doi.org/10.3133/sir20095243.","productDescription":"xi, 88p.","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":476,"text":"North Carolina Water Science Center","active":true,"usgs":true}],"links":[{"id":125364,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/sir_2009_5243.jpg"},{"id":13490,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/sir/2009/5243/","linkFileType":{"id":5,"text":"html"}}],"geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -65,23 ], [ -65,50 ], [ -125,50 ], [ -125,23 ], [ -65,23 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b32e4b07f02db6b4890","contributors":{"authors":[{"text":"Kashuba, Roxolana","contributorId":82814,"corporation":false,"usgs":true,"family":"Kashuba","given":"Roxolana","affiliations":[],"preferred":false,"id":304731,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Cha, YoonKyung","contributorId":9741,"corporation":false,"usgs":true,"family":"Cha","given":"YoonKyung","email":"","affiliations":[],"preferred":false,"id":304728,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Alameddine, Ibrahim","contributorId":22459,"corporation":false,"usgs":true,"family":"Alameddine","given":"Ibrahim","email":"","affiliations":[],"preferred":false,"id":304730,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Lee, Boknam","contributorId":14533,"corporation":false,"usgs":true,"family":"Lee","given":"Boknam","email":"","affiliations":[],"preferred":false,"id":304729,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Cuffney, Thomas F. 0000-0003-1164-5560 tcuffney@usgs.gov","orcid":"https://orcid.org/0000-0003-1164-5560","contributorId":517,"corporation":false,"usgs":true,"family":"Cuffney","given":"Thomas","email":"tcuffney@usgs.gov","middleInitial":"F.","affiliations":[{"id":13634,"text":"South Atlantic Water Science Center","active":true,"usgs":true}],"preferred":true,"id":304727,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

These lakes are downwind of sources of atmospheric inputs originating from mining, industrial, urban, agricultural and natural sources that are distributed within tens to hundreds of kilometers west and south of the Uinta Mountains.

Over the last century, sediments in Marshall Lake, which is closer to the Wasatch Front and receives more precipitation than Hidden Lake, received twice the concentrations of metals and phosphorus as Hidden Lake. Comparison of diatom and elemental data reveals coeval changes in geochemistry and diatom assemblages at Marshall Lake, but not at Hidden Lake; however, a major shift in diatom assemblages occurs at Hidden Lake in the seventeenth century. The change in diatoms at Marshall Lake is marked by the near disappearance of&nbsp;</span><i>Cyclotella stelligera</i><span>&nbsp;and&nbsp;</span><i>C. pseudostelligera</i><span>&nbsp;and an increase in benthic, metal-tolerant diatoms. This change is similar to changes in other lakes that have been attributed to metal pollution. The marked change in diatom assemblages at Hidden Lake indicates a shift in lake-water pH from somewhat acidic to circumneutral. We hypothesize that this change in pH is related to drought-induced changes in input of carbonate-rich desert dust.</span></p>","language":"English","publisher":"Springer","doi":"10.1007/s10750-010-0145-7","usgsCitation":"Moser, K., Mordecai, J.S., Reynolds, R.L., Rosenbaum, J.G., and Ketterer, M.E., 2010, Diatom changes in two Uinta mountain lakes, Utah, USA: Responses to anthropogenic and natural atmospheric inputs: Hydrobiologia, v. 648, p. 91-108, https://doi.org/10.1007/s10750-010-0145-7.","productDescription":"18 p.","startPage":"91","endPage":"108","costCenters":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"links":[{"id":374064,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Utah","otherGeospatial":"Uintas Mountains","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -111.70074462890625,\n              40.168380093142446\n            ],\n            [\n              -109.368896484375,\n              40.168380093142446\n            ],\n            [\n              -109.368896484375,\n              40.863679665481676\n            ],\n            [\n              -111.70074462890625,\n              40.863679665481676\n            ],\n            [\n              -111.70074462890625,\n              40.168380093142446\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"648","noUsgsAuthors":false,"publicationDate":"2010-03-04","publicationStatus":"PW","contributors":{"authors":[{"text":"Moser, Katrina","contributorId":53487,"corporation":false,"usgs":true,"family":"Moser","given":"Katrina","email":"","affiliations":[],"preferred":false,"id":787319,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Mordecai, Jessica S.","contributorId":224206,"corporation":false,"usgs":false,"family":"Mordecai","given":"Jessica","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":787320,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Reynolds, Richard L. 0000-0002-4572-2942 rreynolds@usgs.gov","orcid":"https://orcid.org/0000-0002-4572-2942","contributorId":139068,"corporation":false,"usgs":true,"family":"Reynolds","given":"Richard","email":"rreynolds@usgs.gov","middleInitial":"L.","affiliations":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"preferred":true,"id":787321,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Rosenbaum, Joseph G. jrosenbaum@usgs.gov","contributorId":1524,"corporation":false,"usgs":true,"family":"Rosenbaum","given":"Joseph","email":"jrosenbaum@usgs.gov","middleInitial":"G.","affiliations":[],"preferred":true,"id":787322,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Ketterer, Michael E.","contributorId":28479,"corporation":false,"usgs":true,"family":"Ketterer","given":"Michael","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":787323,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

An understanding of biogeochemical redox processes is crucial for predicting and protecting environmental health and can provide new opportunities for engineered remediation strategies. Energy can be released and stored by means of redox reactions via the oxidation of labile organic carbon or inorganic compounds (electron donors) by microorganisms coupled to the reduction of electron acceptors including humic substances, iron-bearing minerals, transition metals, metalloids, and actinides. Environmental redox processes play key roles in the formation and dissolution of mineral phases. Redox cycling of naturally occurring trace elements and their host minerals often controls the release or sequestration of inorganic contaminants. Redox processes control the chemical speciation, bioavailability, toxicity, and mobility of many major and trace elements including Fe, Mn, C, P, N, S, Cr, Cu, Co, As, Sb, Se, Hg, Tc, and U.

Streambed sediment from 16 sampling sites and stream-water samples from 5 sites were collected at or near Fort Riley and analyzed for as many as 17 energetic compounds, 65 SVOCs, and 27 trace elements.\r\n\r\nNone of the energetic compounds or SVOCs were detected in streambed sediment collected from sites within the Fort Riley Military Reservation. This may indicate that these compounds either are not transported from dispersal areas or that analytical methods are not sensitive enough to detect the small concentrations that may be transported. Concentrations of munitions-associated trace elements did not exceed sediment-quality guidelines recommended by the U.S. Environmental Protection Agency (USEPA) and are not indicative of contamination of streambed sediment at selected streambed sampling sites, at least in regards to movement from dispersal areas.\r\n\r\nAnalytical results of stream-water samples provided little evidence of contamination by energetic compounds, SVOCs, or associated trace elements. Perchlorate was detected in 19 of 20 stream-water samples at concentrations ranging from an estimated 0.057 to an estimated 0.236 ug/L (micrograms per liter) with a median concentration of an estimated 0.114 ug/L, substantially less than the USEPA Interim Health Advisory criterion (15 ug/L), and is in the range of documented background concentrations. Because of these small concentrations and possible natural sources (precipitation and groundwater), it is likely that the occurrence of perchlorate in stream water is naturally occurring, although a definitive identification of the source of perchlorate in stream water at Fort Riley is difficult. The only SVOCs detected in stream-water samples were bis(2-ethylhexyl) phthalate and di-n-butyl phthalate but at concentrations substantially less than the most stringent aquatic-life criteria established by the Kansas Department of Health and Environment. All trace element concentrations in stream-water samples were less than the most stringent aquatic-life criteria. The implication of these stream-water results is that contamination arising from firing-range activities, if it exists, is so small as to be nondetectable with current analytical methods or is not distinguishable from background concentrations for constituents that also are naturally occurring. Overall, the munitions-related constituents analyzed in streambed sediment and stream water, when detected, were at concentrations that were less than regulatory criteria\r\n","language":"ENGLISH","publisher":"U.S. Geological Survey","doi":"10.3133/sir20105021","collaboration":"Prepared in cooperation with the U.S. Army","usgsCitation":"Coiner, R., Pope, L.M., and Mehl, H.E., 2010, Assessment of Energetic Compounds, Semi-volatile Organic Compounds, and Trace Elements in Streambed Sediment and Stream Water from Streams Draining Munitions Firing Points and Impact Areas, Fort Riley, Kansas, 2007-08: U.S. Geological Survey Scientific Investigations Report 2010-5021, vii, 55 p., https://doi.org/10.3133/sir20105021.","productDescription":"vii, 55 p.","onlineOnly":"N","additionalOnlineFiles":"N","temporalStart":"2007-01-01","temporalEnd":"2008-12-31","costCenters":[{"id":353,"text":"Kansas Water Science Center","active":false,"usgs":true}],"links":[{"id":125792,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/sir_2010_5021.jpg"},{"id":13487,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/sir/2010/5021/","linkFileType":{"id":5,"text":"html"}}],"geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -96.95,39.016666666666666 ], [ -96.95,39.31666666666667 ], [ -96.68333333333334,39.31666666666667 ], [ -96.68333333333334,39.016666666666666 ], [ -96.95,39.016666666666666 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4abbe4b07f02db67298d","contributors":{"authors":[{"text":"Coiner, R.L.","contributorId":64212,"corporation":false,"usgs":true,"family":"Coiner","given":"R.L.","email":"","affiliations":[],"preferred":false,"id":304725,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Pope, L.

The field study was conducted from January 26 to February 3, 2010, and included investigations in Port-au-Prince and the heavily damaged communities to the west, including Leogane, Grand Goave, Petite Goave, and Oliver. \r\n\r\nSeismology\r\nDespite recent seismic quiescence, Haiti has suffered similar devastating earthquakes in the historical past (1701, 1751, 1770 and 1860). Despite this knowledge of historical seismicity, Haiti had no seismograph stations during the main earthquake, so it is impossible to estimate accurately the intensity of ground motions. Nonetheless, the wide range of buildings damaged by the January 12, 2010, earthquake suggests that the ground motions contained seismic energy over a wide range of frequencies. Another earthquake of similar magnitude could strike at any time on the eastern end of the Enriquillo Fault, directly to the south of Port-au-Prince. Reconstruction must take this hazard into account. \r\n\r\nThe four portable seismographs installed by the team recorded a series of small aftershocks. As expected, the ground motions recorded at a hard-rock site contained a greater proportion of high frequencies than the motions recorded at a soil site. Two of the stations continue to monitor seismic activity. \r\n\r\nA thorough field investigation of the mapped Enriquillo Fault south of the city of Leogane failed to find any evidence of surface faulting. This led the team to conclude that the earthquake was unlikely to have produced any surface rupture in the study area. \r\n\r\nGeotechnical Aspects\r\nSoil liquefaction, landslides and rockslides in cut slopes, and road embankment failures contributed to extensive damage in Port-au-Prince and elsewhere. A lack of detailed knowledge of the physical conditions of the soils (for example, lithology, stiffness, density, and thickness) made it difficult for us to quantitatively assess the role of ground-motion amplification in the widespread damage. \r\n\r\nBuildings\r\nThe Haitian Ministry of Statistics and Informatics reported that one-story buildings represent 73 percent of the building inventory. Most ordinary, one-story houses have roofs made of sheet metal (82 percent), whereas most multistory houses and apartments have roofs made of concrete (71 percent). Walls made of concrete/block/stone predominate both in ordinary houses and apartments. \r\n\r\nIt appears that the widespread damage to residences and commercial and government buildings was attributable to a great extent to the lack of earthquake-resistant design. In many cases, the structural types, member dimensions, and detailing practices were inadequate to resist strong ground motions. These vulnerabilities may have been exacerbated by poor construction practices. Reinforced concrete frames with concrete block masonry infill appeared to perform particularly poorly. Structures with light (timber or sheet metal) roofs performed better compared to structures with concrete roofs and slabs. \r\n\r\nThe seismic performance of some buildings was adequate, and some of the damaged buildings appeared to have had low deformation demands. These observations suggest that structures designed and constructed with adequate stiffness and reinforcing details would have resisted the earthquake without being damaged severely. \r\n\r\nA damage survey of 107 buildings in downtown Port-au-Prince indicated that 28 percent had collapsed and another 33 percent were damaged enough to require repairs. A similar survey of 52 buildings in Leogane found that 62 percent had collapsed and another 31 percent required repairs. \r\n\r\nBridges\r\nThere was no evidence of bridge collapses attributable to the earthquake. Most bridges in Port-au-Prince are simple box culverts consisting of box girders 2.0 to 2.","language":"ENGLISH","publisher":"U.S. Geological Survey","doi":"10.3133/ofr20101048","collaboration":"With material support from Earthquake Engineering Research Institute, U.S. National Science Foundation, National Earthquake Hazards Reduction Program, U.S. Agency for International Development, U.S. Southern Command, Applied Technology Council, Geo-Engineering Extreme Events Reconnaissance Association, and Network for Earthquake Engineering Simulation","usgsCitation":"Eberhard, M.O., Baldridge, S., Marshall, J., Mooney, W., and Rix, G., 2010, The MW 7.0 Haiti Earthquake of January 12, 2010: USGS/EERI Advance Reconnaissance Team Report: U.S. Geological Survey Open-File Report 2010-1048, vi, 58 p., https://doi.org/10.3133/ofr20101048.","productDescription":"vi, 58 p.","onlineOnly":"Y","additionalOnlineFiles":"N","temporalStart":"2010-01-26","temporalEnd":"2010-02-03","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":125791,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr_2010_1048.jpg"},{"id":13488,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2010/1048/","linkFileType":{"id":5,"text":"html"}}],"geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -80,25 ], [ -80,15 ], [ -65,15 ], [ -65,25 ], [ -80,25 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ac8e4b07f02db67b98f","contributors":{"authors":[{"text":"Eberhard, Marc O.","contributorId":11575,"corporation":false,"usgs":true,"family":"Eberhard","given":"Marc","email":"","middleInitial":"O.","affiliations":[],"preferred":false,"id":304719,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Baldridge, Steven","contributorId":91823,"corporation":false,"usgs":true,"family":"Baldridge","given":"Steven","email":"","affiliations":[],"preferred":false,"id":304723,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Marshall, Justin","contributorId":55790,"corporation":false,"usgs":true,"family":"Marshall","given":"Justin","email":"","affiliations":[],"preferred":false,"id":304722,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Mooney, Walter","contributorId":40952,"corporation":false,"usgs":true,"family":"Mooney","given":"Walter","affiliations":[],"preferred":false,"id":304720,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Rix, Glenn J.","contributorId":41393,"corporation":false,"usgs":true,"family":"Rix","given":"Glenn J.","affiliations":[],"preferred":false,"id":304721,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}
