We evaluated the efficacy of environmental DNA (eDNA) analysis for improving detection and thus potentially refining the known distribution of Chinook salmon (</span><i>Oncorhynchus tshawytscha</i><span>) in the Methow and Okanogan Subbasins of the Upper Columbia River, which span the border between Washington, USA and British Columbia, Canada. We developed an assay to target a 90 base pair sequence of Chinook DNA and used quantitative polymerase chain reaction (qPCR) to quantify the amount of Chinook eDNA in triplicate 1-L water samples collected at 48 stream locations in June and again in August 2012. The overall probability of detecting Chinook with our eDNA method in areas within the known distribution was 0.77 (&plusmn;0.05&nbsp;SE). Detection probability was lower in June (0.62, &plusmn;0.08&nbsp;SE) during high flows and at the beginning of spring Chinook migration than during base flows in August (0.93, &plusmn;0.04&nbsp;SE). In the Methow subbasin, mean eDNA concentration was higher in August compared to June, especially in smaller tributaries, probably resulting from the arrival of spring Chinook adults, reduced discharge, or both. Chinook eDNA concentrations did not appear to change in the Okanogan subbasin from June to August. Contrary to our expectations about downstream eDNA accumulation, Chinook eDNA did not decrease in concentration in upstream reaches (0&ndash;120&nbsp;km). Further examination of factors influencing spatial distribution of eDNA in lotic systems may allow for greater inference of local population densities along stream networks or watersheds. These results demonstrate the potential effectiveness of eDNA detection methods for determining landscape-level distribution of anadromous salmonids in large river systems.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.biocon.2014.11.025","usgsCitation":"Laramie, M.B., Pilliod, D., and Goldberg, C.S., 2015, Characterizing the distribution of an endangered salmonid using environmental DNA analysis: Biological Conservation, v. 183, p. 29-37, https://doi.org/10.1016/j.biocon.2014.11.025.","productDescription":"9 p.","startPage":"29","endPage":"37","numberOfPages":"9","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-059842","costCenters":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true}],"links":[{"id":472314,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1016/j.biocon.2014.11.025","text":"Publisher Index Page"},{"id":297643,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Canada, United States","state":"British Columbia, Washington","otherGeospatial":"Upper Columbia River","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -120.83312988281249,\n              48.026672195435985\n            ],\n            [\n              -120.83312988281249,\n              49.66762782262192\n            ],\n            [\n              -118.87207031250001,\n              49.66762782262192\n            ],\n            [\n              -118.87207031250001,\n              48.026672195435985\n            ],\n            [\n              -120.83312988281249,\n              48.026672195435985\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"183","publicComments":"Special Issue: Environmental DNA: A powerful new tool for biological conservation","publishingServiceCenter":{"id":12,"text":"Tacoma PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"54dd2a5de4b08de9379b3014","contributors":{"authors":[{"text":"Laramie, Matthew B. mlaramie@usgs.gov","contributorId":5627,"corporation":false,"usgs":true,"family":"Laramie","given":"Matthew","email":"mlaramie@usgs.gov","middleInitial":"B.","affiliations":[{"id":289,"text":"Forest and Rangeland Ecosys Science Center","active":true,"usgs":true}],"preferred":false,"id":539624,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Pilliod, David S. 0000-0003-4207-3518 dpilliod@usgs.gov","orcid":"https://orcid.org/0000-0003-4207-3518","contributorId":161,"corporation":false,"usgs":true,"family":"Pilliod","given":"David S.","email":"dpilliod@usgs.gov","affiliations":[{"id":289,"text":"Forest and Rangeland Ecosys Science Center","active":true,"usgs":true}],"preferred":false,"id":539625,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Goldberg, Caren S.","contributorId":76879,"corporation":false,"usgs":false,"family":"Goldberg","given":"Caren","email":"","middleInitial":"S.","affiliations":[{"id":5132,"text":"Washington State University, Pullman","active":true,"usgs":false}],"preferred":false,"id":539626,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Such early detection requires sensitive survey tools that can detect low numbers of individuals. Due to their high sensitivity, environmental DNA (eDNA) surveys hold promise as an early detection method for aquatic invasive species. Quantification of eDNA amounts may also provide data on species abundance and timing of an organism&rsquo;s presence, allowing managers to successfully combat the spread of ecologically damaging species. To better understand the link between eDNA and an organism&rsquo;s presence, it is crucial to know how eDNA is shed into the environment. Our study used quantitative PCR (qPCR) and controlled laboratory experiments to measure the amount of eDNA that two species of invasive bigheaded carps (</span><i>Hypophthalmichthys nobilis</i> and <i>Hypophthalmichthys&nbsp;</i><i>molitrix</i><span>) shed into the water. We first measured how much eDNA a single fish sheds and the variability of these measurements. Then, in a series of manipulative lab experiments, we studied how temperature, biomass (grams of fish), and diet affect the shedding rate of eDNA by these fish. We found that eDNA amounts exhibit a positive relationship with fish biomass, and that feeding could increase the amount of eDNA shed by ten-fold, whereas water temperature did not have an effect. Our results demonstrate that quantification of eDNA may be useful for predicting carp density, as well as densities of other rare or invasive species.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.biocon.2014.11.020","usgsCitation":"Klymus, K.E., Richter, C.A., Chapman, D., and Paukert, C.P., 2015, Quantification of eDNA shedding rates from invasive bighead carp Hypophthalmichthys nobilis and silver carp Hypophthalmichthys molitrix: Biological Conservation, v. 183, p. 77-84, https://doi.org/10.1016/j.biocon.2014.11.020.","productDescription":"8 p.","startPage":"77","endPage":"84","numberOfPages":"8","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-053423","costCenters":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true},{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true}],"links":[{"id":297640,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"183","publishingServiceCenter":{"id":4,"text":"Rolla PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"54dd2aa5e4b08de9379b3165","chorus":{"doi":"10.1016/j.biocon.2014.11.020","url":"http://dx.doi.org/10.1016/j.biocon.2014.11.020","publisher":"Elsevier BV","authors":"Klymus Katy E., Richter Catherine A., Chapman Duane C., Paukert Craig","journalName":"Biological Conservation","publicationDate":"3/2015","auditedOn":"1/11/2015"},"contributors":{"authors":[{"text":"Klymus, Katy E. 0000-0002-8843-6241 kklymus@usgs.gov","orcid":"https://orcid.org/0000-0002-8843-6241","contributorId":5043,"corporation":false,"usgs":true,"family":"Klymus","given":"Katy","email":"kklymus@usgs.gov","middleInitial":"E.","affiliations":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"preferred":true,"id":539585,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Richter, Cathy A. 0000-0001-7322-4206 crichter@usgs.gov","orcid":"https://orcid.org/0000-0001-7322-4206","contributorId":1878,"corporation":false,"usgs":true,"family":"Richter","given":"Cathy","email":"crichter@usgs.gov","middleInitial":"A.","affiliations":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"preferred":true,"id":539584,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Chapman, Duane 0000-0002-1086-8853 dchapman@usgs.gov","orcid":"https://orcid.org/0000-0002-1086-8853","contributorId":1291,"corporation":false,"usgs":true,"family":"Chapman","given":"Duane","email":"dchapman@usgs.gov","affiliations":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true},{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"preferred":true,"id":539586,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Paukert, Craig P. 0000-0002-9369-8545 cpaukert@usgs.gov","orcid":"https://orcid.org/0000-0002-9369-8545","contributorId":879,"corporation":false,"usgs":true,"family":"Paukert","given":"Craig","email":"cpaukert@usgs.gov","middleInitial":"P.","affiliations":[{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true}],"preferred":true,"id":539587,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Due to their migratory behavior, some may transmit disease over long distances. Migratory connectivity studies can link breeding and nonbreeding grounds while illustrating potential interactions among populations that may spread diseases. We investigated Dunlin (<i>Calidris alpina</i>), a shorebird with a subspecies (<i>C.&nbsp;a.&nbsp;arcticola</i>) that migrates from nonbreeding areas endemic to avian influenza in eastern Asia to breeding grounds in northern Alaska. Using microsatellites and mitochondrial DNA, we illustrate genetic structure among six subspecies: <i>C.&nbsp;a.&nbsp;arcticola</i>,<i> C.&nbsp;a.&nbsp;pacifica</i>,<i> C.&nbsp;a.&nbsp;hudsonia</i>,<i> C.&nbsp;a.&nbsp;sakhalina</i>,<i> C.&nbsp;a.&nbsp;kistchinski</i>, and <i>C.&nbsp;a.&nbsp;actites</i>.

Our data reveal asymmetric intercontinental gene flow, with some <i>C.&nbsp;a.&nbsp;arcticola</i> short-stopping migration to breed with <i>C.&nbsp;a.&nbsp;pacifica</i> in western Alaska.

We conducted a radio telemetry study to characterize movement and habitat use of introduced male Argentine black and white tegus (<i>Tupinambis merianae</i>) in the Everglades of southern Florida from May to August 2012 at the core and periphery of the introduced range. Tegus at the periphery moved farther per day (mean 131.7 &plusmn; 11.6 m, n = 6) compared to tegus at the core (mean 50.3 &plusmn; 12.4 m, n = 6). However, activity ranges were not significantly smaller in the core (mean 19.4 &plusmn; 8.4 ha, n = 6) compared to periphery (mean 29.1 &plusmn; 5.2 ha, n = 6). Peripheral activity ranges were more linear due to activity being largely restricted to levee habitat surrounded by open water or marsh. Tegus were located in shrub or tree habitat (mean 96%) more often than expected based on random locations (mean 58%), and the percent cover of trees and shrubs was higher in activity ranges (mean 61%) than the general study area (17%). Our study highlighted the ability of tegus to spread across the Florida landscape, especially in linear disturbed habitats where increased movement occurred and in areas of altered hydrology where movement is not restricted by water.</p>","language":"English","publisher":"Springer","doi":"10.1007/s10530-014-0834-7","usgsCitation":"Klug, P.E., Reed, R., Mazzotti, F., McEachern, M., Vinci, J.J., Craven, K.K., and Yackel Adams, A.A., 2015, The influence of disturbed habitat on the spatial ecology of Argentine black and white tegu (<i>Tupinambis merianae</i>), a recent invader in the Everglades ecosystem (Florida, USA): Biological Invasions, v. 17, no. 6, p. 1785-1797, https://doi.org/10.1007/s10530-014-0834-7.","productDescription":"13 p.","startPage":"1785","endPage":"1797","numberOfPages":"13","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-054967","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":297638,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Florida","county":"Miami-Dade County","otherGeospatial":"Everglades","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -81.947021484375,\n              25.055745117015316\n            ],\n            [\n              -81.947021484375,\n              26.828972753817787\n            ],\n            [\n              -79.7442626953125,\n              26.828972753817787\n            ],\n            [\n              -79.7442626953125,\n              25.055745117015316\n            ],\n            [\n              -81.947021484375,\n              25.055745117015316\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"17","issue":"6","publishingServiceCenter":{"id":2,"text":"Denver PSC"},"noUsgsAuthors":false,"publicationDate":"2015-01-04","publicationStatus":"PW","scienceBaseUri":"54dd2abfe4b08de9379b31d0","contributors":{"authors":[{"text":"Klug, Page E. pklug@usgs.gov","contributorId":5545,"corporation":false,"usgs":true,"family":"Klug","given":"Page","email":"pklug@usgs.gov","middleInitial":"E.","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":true,"id":539556,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Reed, Robert N. reedr@usgs.gov","contributorId":1686,"corporation":false,"usgs":true,"family":"Reed","given":"Robert N.","email":"reedr@usgs.gov","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":false,"id":539557,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Mazzotti, Frank J.","contributorId":100018,"corporation":false,"usgs":false,"family":"Mazzotti","given":"Frank J.","affiliations":[{"id":12557,"text":"University of Florida, FLREC","active":true,"usgs":false}],"preferred":false,"id":539561,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"McEachern, Michelle A. mmceachern@usgs.gov","contributorId":5539,"corporation":false,"usgs":true,"family":"McEachern","given":"Michelle A.","email":"mmceachern@usgs.gov","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":true,"id":539560,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Vinci, Joy J.","contributorId":138977,"corporation":false,"usgs":false,"family":"Vinci","given":"Joy","email":"","middleInitial":"J.","affiliations":[{"id":12604,"text":"Department of Wildlife Ecology and Conservation, Fort Lauderdale Research and Education Center, 3205 College Avenue, University of Florida, Davie, FL 33314, USA","active":true,"usgs":false}],"preferred":false,"id":539562,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Craven, Katelin K. kcraven@usgs.gov","contributorId":5286,"corporation":false,"usgs":true,"family":"Craven","given":"Katelin","email":"kcraven@usgs.gov","middleInitial":"K.","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":false,"id":539559,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Yackel Adams, Amy A. 0000-0002-7044-8447 yackela@usgs.gov","orcid":"https://orcid.org/0000-0002-7044-8447","contributorId":3116,"corporation":false,"usgs":true,"family":"Yackel Adams","given":"Amy","email":"yackela@usgs.gov","middleInitial":"A.","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":true,"id":539558,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

Water samples were collected from 11 monitoring wells completed in about 250&ndash;750 feet of the upper part of the aquifer, and samples were analyzed for selected major ions, trace elements, nutrients, radiochemical constituents, and stable isotopes. Each well was equipped with a multilevel monitoring system containing four to seven sampling ports that were each isolated by permanent packer systems. The sampling ports were installed in aquifer zones that were highly transmissive and that represented the water chemistry of the top three to five model layers of a steady-state and transient groundwater‑flow model.

Currently, at least 18 estuaries coastwide host spawning populations and the viability of these vary, requiring differing levels of protection. Subadults emigrate from their natal estuaries to marine waters where they are vulnerable to bycatch; one of the major threats to the rebuilding of populations. As a result, identifying the population origin of Atlantic Sturgeon in coastal waters is critical to development of management plans intended to minimize interactions of the most imperiled populations with damaging fisheries. We used mitochondrial DNA control region sequencing and microsatellite DNA analyses to determine the origin of 261 Atlantic Sturgeon collected off the Delaware coast during the spring months. Using individual-based assignment (IBA) testing and mixed stock analysis, we found that specimens originated from all nine of our reference populations and the five DPSs used in the listing determination. Using IBA, we found that the Hudson River population was the largest contributor (38.3%) to our coastal collection. The James (19.9%) and Delaware (13.8%) river populations, at one time thought to be extirpated or nearly so, were the next largest contributors. The three populations combined in the South Atlantic DPS contributed 21% of specimens; the Altamaha River, the largest population in the South Atlantic DPS, only contributed a single specimen to the collection. While the origin of specimens collected on the Delaware coast was most likely within rivers of the New York Bight DPS (52.1%), specimens that originated elsewhere were also well represented. Genetic analyses provide a robust tool to identify the population origin of individual sturgeon outside of their natal estuaries and to determine the quantitative contributions of individual populations to coastal aggregations that are vulnerable to bycatch and other anthropogenic threats.</span></p>","language":"English","publisher":"American Fisheries Society","doi":"10.1080/02755947.2014.963751","usgsCitation":"Wirgin, I., Breece, M.W., Fox, D.A., Maceda, L., Wark, K.W., and King, T.L., 2015, Origin of Atlantic Sturgeon collected off the Delaware coast during spring months: North American Journal of Fisheries Management, v. 35, no. 1, p. 20-30, https://doi.org/10.1080/02755947.2014.963751.","productDescription":"11 p.","startPage":"20","endPage":"30","numberOfPages":"11","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-056177","costCenters":[{"id":365,"text":"Leetown Science Center","active":true,"usgs":true}],"links":[{"id":297629,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Delaware","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -75.05722045898438,\n              38.49121932062687\n            ],\n            [\n              -75.05722045898438,\n              38.585746636004494\n            ],\n            [\n              -74.88006591796874,\n              38.585746636004494\n            ],\n            [\n              -74.88006591796874,\n              38.49121932062687\n            ],\n            [\n              -75.05722045898438,\n              38.49121932062687\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"35","issue":"1","publishingServiceCenter":{"id":10,"text":"Baltimore PSC"},"noUsgsAuthors":false,"publicationDate":"2015-01-12","publicationStatus":"PW","scienceBaseUri":"54dd2aa0e4b08de9379b314a","contributors":{"authors":[{"text":"Wirgin, Isaac","contributorId":138929,"corporation":false,"usgs":false,"family":"Wirgin","given":"Isaac","affiliations":[{"id":12583,"text":"New York University School of Medicine Tuxedo, New York, UNITED STATES","active":true,"usgs":false}],"preferred":false,"id":539283,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Breece, Matthew W.","contributorId":116999,"corporation":false,"usgs":false,"family":"Breece","given":"Matthew","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":539580,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Fox, Dewayne A.","contributorId":117052,"corporation":false,"usgs":false,"family":"Fox","given":"Dewayne","email":"","middleInitial":"A.","affiliations":[{"id":12970,"text":"Department of Agriculture and Natural Resources, Delaware State University","active":true,"usgs":false}],"preferred":false,"id":539581,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Maceda, Lorraine","contributorId":138930,"corporation":false,"usgs":false,"family":"Maceda","given":"Lorraine","email":"","affiliations":[{"id":12584,"text":"New York University School of Medicine, Tuxedo, New York UNITED STATES","active":true,"usgs":false}],"preferred":false,"id":539284,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Wark, Kevin W.","contributorId":116263,"corporation":false,"usgs":false,"family":"Wark","given":"Kevin","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":539582,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"King, Tim L. tlking@usgs.gov","contributorId":3520,"corporation":false,"usgs":true,"family":"King","given":"Tim","email":"tlking@usgs.gov","middleInitial":"L.","affiliations":[{"id":365,"text":"Leetown Science Center","active":true,"usgs":true}],"preferred":true,"id":539282,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

The CSMP approach is to create highly detailed seafloor maps through collection, integration, interpretation, and visualization of swath sonar data, acoustic backscatter, seafloor video, seafloor photography, high-resolution seismic-reflection profiles, and bottom-sediment sampling data. The map products display seafloor morphology and character, identify potential marine benthic habitats, and illustrate both the surficial seafloor geology and shallow (to about 100 m) subsurface geology.&nbsp;</p>\n<p>The Offshore of Pacifica map area is located in northern California, on the Pacific coast of the San Francisco Peninsula about 10 kilometers south of the Golden Gate. The map area extends from Daly City, through Pacifica, to the small coastal community of Montara. Much of the coastal zone is managed by either the State of California or local governments, including Thornton Beach State Park, Mussel Rock Park, Pacifica State Beach, Gray Whale Cove State Beach, and Montara State Beach.</p>\n<p>The major structure in the transform boundary between the Pacific and North American tectonic plates, the northwest-striking San Andreas Fault, cuts through the map area, crossing the shoreline near Mussel Rock before continuing offshore. The epicenter of the great 1906 California earthquake is located on the offshore part of the San Andreas Fault Zone a few kilometers north of the map area.&nbsp;</p>\n<p>The map area is located at the northwest end of the Santa Cruz Mountains, much of which has been uplifted in the last 400,000 years. Southwest of the San Andreas Fault Zone, this uplift has resulted in a highly variable coastal morphology characterized by long, narrow beaches bounded by steep cliffs or marine terraces, small pocket beaches surrounded by rocky promontories, and steep, narrow coastal watersheds. Geologic units mapped along the coast include sedimentary, volcanic, and metamorphic rocks of the Franciscan Complex; Cretaceous granitic rocks; Tertiary sedimentary rocks; and Quaternary coastal marine terraces, deep-seated and shallow landslides, and beach and sand dune deposits, all of which contribute sediment to the coastal zone.</p>\n<p>In contrast to the more rural coastal zone to the south, the highly urbanized coastal zone north of Mussel Rock and the San Andreas Fault Zone is characterized by a narrow beach bounded by steep, 50- to 120-m-high cliffs made up of sand, silt, and clay of the Pliocene and Pleistocene Merced Formation, the source of numerous landslides. Two large landslides along &ldquo;Northridge bluff&rdquo; in 2003 and 2007 had estimated volumes of 305,800 to 382,300 m<sup>3</sup>&nbsp;and 120,800 m<sup>3</sup>, respectively. Coastal landslides also are an issue to the south between Mussel Rock and Mori Point, even as bluffs diminish in height and pocket beaches transition to a more continuous strand bounded by Quaternary-age dunes and low-lying marine terraces. Mori Point, a coastal promontory in Pacifica underlain by rocks of the Franciscan Complex, rises abruptly to a height of 90 m from the shoreline. Pocket beaches characterize the shoreline from Mori Point south to Shelter Cove, the largest of which, Pacifica State Beach, is at the mouth of San Pedro Creek.&nbsp;</p>\n<p>The coastal zone south of Pacifica, which stretches from Shelter Cove to Montara and includes Point San Pedro and Devils Slide, lies at the northwest end of San Pedro Mountain (underlain largely by early Tertiary sedimentary rocks) and Montara Mountain (underlain by Cretaceous granitic rocks). Elevations at Montara Mountain exceed 500 m just 4 km from the shoreline, and steep cliffs along the coast are as high as 275 m. This rugged terrain results in numerous rocky promontories, small pocket beaches, and large coastal landslides. Slope failures along Devils Slide are notorious for closing California Highway 1, creating such a large and persistent problem that the California Department of Transportation has bypassed this coastal section by tunneling through San Pedro Mountain; the tunnel was completed and the new section of highway opened in 2013. Coastal relief diminishes at Montara in the southernmost part of the map area, where the shoreline is bounded by 10- to 20-m-high marine terraces.</p>\n<p>Throughout the year, this part of the coast is exposed to the north Pacific swell, the southern swell, northwest wind waves, and local wind waves. The north Pacific swell dominates in winter months, having wave heights that range from 2 to 10 m at offshore buoys and wave periods that range from 10 to 25 s. During summer months, the largest waves come from the southern swell, generated by storms in the south Pacific and offshore of Central America. Characteristically, these swells have smaller wave heights (0.3&ndash;3 m) but similarly long wave periods (10&ndash;25 s). Local wind waves are most common from October to April, whereas northwest wind waves affect the coast throughout the year. These two wind-wave regimes typically have wave heights of 1 to 4 m and short wave periods (3&ndash;10 s).&nbsp;</p>\n<p>Unlike many other parts of the California coast where sediment is supplied primarily from river and (or) stream runoff, sediment supply to the offshore along this part of northern California is a complex mixture of (1) sand transported from the coast north of the Golden Gate, (2) sediment transported to the coast through the San Francisco Bay via the Golden Gate and then dispersed over the adjacent ebb-tide delta, and (3) varying volumes of sediment eroded from adjacent steep coastal bluffs caused by wave-induced landslides and other erosional events. Additionally, since the 1980s, coastal erosion south of the Golden Gate has increased substantially between Ocean Beach (on the west coast of San Francisco, about 5 km north of the map area) and Point San Pedro. The combined sediment load is transported southward along the coast by the generally north-to-south alongshore current, which develops in response to the energetic winter-wave climate associated with the north Pacific swell. Overall, beaches in the map area have a long-term erosional trend, except near Mussel Rock where a long-term accretionary trend may reflect increased sediment supply from landslides. Beach-front riprap armoring and retaining walls are used locally to protect the shoreline from seasonal storm waves, most notably between Mussel Rock and Mori Point.</p>\n<p>The continental shelf in the map area is about 40 km wide, with water depths at the shelf break that range from about 80 to 120 m. Within California&rsquo;s State Waters, the midshelf to inner shelf areas are characterized by a relatively flat, shallow (water depths of as much as 44 m) seafloor that dips gently (about 0.2&deg; to 0.3&deg;) westward. The seafloor is composed primarily of unconsolidated Holocene sediment (marine deposits), as well as some nearshore bedrock outcrops that consist primarily of rocks of the Tertiary Purisima Formation and also Cretaceous plutonic rocks (granite or granodiorite).</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr20141260","usgsCitation":"Edwards, B.D., Phillips, E.L., Dartnell, P., Greene, H., Bretz, C., Kvitek, R.G., Hartwell, S.R., Johnson, S.Y., Cochrane, G.R., Dieter, B., Sliter, R.W., Ross, S.L., Golden, N., Watt, J.T., Chinn, J.L., Erdey, M.D., Krigsman, L., Manson, M., and Endris, C.A., 2015, California State Waters Map Series — Offshore of Pacifica, California: U.S. Geological Survey Open-File Report 2014-1260, Report: iv, 38 p.; 10 Sheets: 48.00 × 36.00 inches or smaller; Metadata; Data Catalog, https://doi.org/10.3133/ofr20141260.","productDescription":"Report: iv, 38 p.; 10 Sheets: 48.00 × 36.00 inches or smaller; Metadata; Data Catalog","numberOfPages":"42","onlineOnly":"Y","additionalOnlineFiles":"N","ipdsId":"IP-052391","costCenters":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":297627,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr20141260.gif"},{"id":297624,"rank":10,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/2014/1260/downloads/ofr2014-1260_sheet8.pdf","text":"Sheet 8","linkFileType":{"id":1,"text":"pdf"},"description":"Sheet 8","linkHelpText":"Seismic-Reflection Profiles, Offshore of Pacifica Map Area, California By Ray W.

Competition can be especially acute for vegetation on Pacific atolls, which depend upon consistent rainfall to replenish shallow groundwater stores. Patterns of sap flow, water use, and diameter growth of <i>Pisonia grandis</i> trees were investigated on Sand Islet, Palmyra Atoll, Line Islands, during a period of low rainfall. Sap flow in the outer sapwood was reduced by 53% for <i>P</i>. <i>grandis</i> trees growing within coconut palm (<i>Cocos nucifera</i>) stands (<i>n</i>&thinsp;=&thinsp;9) versus away from coconut palm (<i>n</i>&thinsp;=&thinsp;9). This suggested that water uptake was being limited by coconut palm. Radial patterns of sap flow into the sapwood of <i>P</i>. <i>grandis</i> also differed between stands with and without coconut palm, such that individual tree water use for <i>P</i>. <i>grandis</i> ranged from 14 to 67&thinsp;L&thinsp;day<sup>&minus;1</sup>, averaging 47&middot;8&thinsp;L&thinsp;day<sup>&minus;1</sup> without coconut palm and 23&middot;6&thinsp;L&thinsp;day<sup>&minus;1</sup> with coconut palm. Diameter growth of <i>P</i>. <i>grandis</i> was measured from nine islets. In contrast to sap flow, competition with coconut palm increased diameter growth by 89%, equating to an individual tree basal area increment of 5&middot;4 versus 10&middot;3&thinsp;mm<sup>2</sup>&thinsp;day<sup>&minus;1</sup>. Greater diameter growth countered by lower rates of water use by <i>P</i>. <i>grandis</i> trees growing in competition with coconut palm suggests that stem swell may be associated with water storage when positioned in the understory of coconut palm, and may facilitate survival when water becomes limiting until too much shading overwhelms <i>P</i>. <i>grandis</i>.&nbsp;</p>","language":"English","publisher":"Wiley","doi":"10.1002/eco.1601","usgsCitation":"Krauss, K.W., Duberstein, J., Cormier, N., Young, H.S., and Hathaway, S.A., 2015, Proximity to encroaching coconut palm limits native forest water use and persistence on a Pacific atoll: Ecohydrology, v. 8, no. 8, p. 1514-1524, https://doi.org/10.1002/eco.1601.","productDescription":"11 p.","startPage":"1514","endPage":"1524","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-052329","costCenters":[{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true}],"links":[{"id":306941,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","otherGeospatial":"Palmyra Atoll","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -162.13760375976562,\n              5.912312054739402\n            ],\n            [\n              -162.1365737915039,\n              5.848448533368537\n            ],\n            [\n              -162.02362060546875,\n              5.848106997539167\n            ],\n            [\n              -162.02722549438474,\n              5.909921573942511\n            ],\n            [\n              -162.13760375976562,\n              5.912312054739402\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"8","issue":"8","publishingServiceCenter":{"id":5,"text":"Lafayette PSC"},"noUsgsAuthors":false,"publicationDate":"2015-01-29","publicationStatus":"PW","scienceBaseUri":"55d5a8b3e4b0518e3546a4de","chorus":{"doi":"10.1002/eco.1601","url":"http://dx.doi.org/10.1002/eco.1601","publisher":"Wiley-Blackwell","authors":"Krauss Ken W., Duberstein Jamie A., Cormier Nicole, Young Hillary S., Hathaway Stacie A.","journalName":"Ecohydrology","publicationDate":"1/29/2015","auditedOn":"2/8/2015"},"contributors":{"authors":[{"text":"Krauss, Ken W. 0000-0003-2195-0729 kraussk@usgs.gov","orcid":"https://orcid.org/0000-0003-2195-0729","contributorId":2017,"corporation":false,"usgs":true,"family":"Krauss","given":"Ken","email":"kraussk@usgs.gov","middleInitial":"W.","affiliations":[{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true},{"id":455,"text":"National Wetlands Research Center","active":true,"usgs":true}],"preferred":true,"id":568611,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Duberstein, Jamie A.","contributorId":91007,"corporation":false,"usgs":false,"family":"Duberstein","given":"Jamie A.","affiliations":[{"id":7084,"text":"Clemson University","active":true,"usgs":false}],"preferred":false,"id":568612,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Cormier, Nicole 0000-0003-2453-9900 cormiern@usgs.gov","orcid":"https://orcid.org/0000-0003-2453-9900","contributorId":4262,"corporation":false,"usgs":true,"family":"Cormier","given":"Nicole","email":"cormiern@usgs.gov","affiliations":[{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true},{"id":455,"text":"National Wetlands Research Center","active":true,"usgs":true}],"preferred":true,"id":568613,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Young, Hillary S.","contributorId":53711,"corporation":false,"usgs":false,"family":"Young","given":"Hillary","email":"","middleInitial":"S.","affiliations":[{"id":13007,"text":"Department of Ecology, Evolution and Marine Biology, University of California, Santa Barbara","active":true,"usgs":false}],"preferred":false,"id":568614,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Hathaway, Stacie A. 0000-0002-4167-8059 sahathaway@usgs.gov","orcid":"https://orcid.org/0000-0002-4167-8059","contributorId":3420,"corporation":false,"usgs":true,"family":"Hathaway","given":"Stacie","email":"sahathaway@usgs.gov","middleInitial":"A.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":568615,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

During the past 30 years these floods resulted in damages within Kansas City costing tens of millions of dollars and more than 25 casualties.</p>\n<p>The U.S. Geological Survey (USGS) and City of Kansas City, Missouri, operate multiple streamgages along the Blue River and tributaries in and near the city. Knowledge of water level at a streamgage is difficult to translate into depth and areal extent of flooding at points distant from the streamgage. One way to address these informational gaps is to produce a library of flood-inundation maps that are referenced to the stages recorded at a streamgage. By referring to the appropriate map, emergency responders can discern the severity of flooding (depth of water and areal extent), identify roads that are or may be flooded, and make plans for notification or evacuation of residents in harm&rsquo;s way for some distance upstream and downstream from the streamgage. The USGS, in cooperation with the city of Kansas City, Missouri, developed a library of flood-inundation maps for the Blue River and selected tributaries.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/fs20153008","usgsCitation":"Heimann, D.C., Weilert, T.E., Kelly, B.P., and Studley, S.E., 2015, Flood-inundation mapping for the Blue River and selected tributaries in Kansas City, Missouri, and vicinity, 2012: U.S. Geological Survey Fact Sheet 2015-3008, 4 p., https://doi.org/10.3133/fs20153008.","productDescription":"4 p.","numberOfPages":"4","onlineOnly":"Y","additionalOnlineFiles":"N","ipdsId":"IP-060253","costCenters":[{"id":396,"text":"Missouri Water Science Center","active":true,"usgs":true}],"links":[{"id":297592,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/fs20153008.jpg"},{"id":297591,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/fs/2015/3008/pdf/fs2015_3008.pdf","text":"Report","size":"5.47 MB","linkFileType":{"id":1,"text":"pdf"},"description":"Report"},{"id":297590,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/fs/2015/3008/"}],"projection":"Web Mercator projection","datum":"North American Datum of 1983","country":"United States","state":"Missouri","city":"Kansas City","otherGeospatial":"Blue River","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -94.75364685058594,\n              38.78406349514289\n            ],\n            [\n              -94.75364685058594,\n              39.184368717303144\n            ],\n            [\n              -94.42955017089844,\n              39.184368717303144\n            ],\n            [\n              -94.42955017089844,\n              38.78406349514289\n            ],\n            [\n              -94.75364685058594,\n              38.78406349514289\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","publishingServiceCenter":{"id":4,"text":"Rolla PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"54dd2a77e4b08de9379b3084","contributors":{"authors":[{"text":"Heimann, David C. 0000-0003-0450-2545 dheimann@usgs.gov","orcid":"https://orcid.org/0000-0003-0450-2545","contributorId":3822,"corporation":false,"usgs":true,"family":"Heimann","given":"David","email":"dheimann@usgs.gov","middleInitial":"C.","affiliations":[{"id":36532,"text":"Central Midwest Water Science Center","active":true,"usgs":true},{"id":396,"text":"Missouri Water Science Center","active":true,"usgs":true}],"preferred":true,"id":539381,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Weilert, Trina E.","contributorId":138563,"corporation":false,"usgs":false,"family":"Weilert","given":"Trina","email":"","middleInitial":"E.","affiliations":[{"id":5108,"text":"U.S. Department of Agriculture Forest Service, Rocky Mountain Research Station, Missoula, Montana 59","active":true,"usgs":false}],"preferred":false,"id":539420,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kelly, Brian P. 0000-0001-6378-2837 bkelly@usgs.gov","orcid":"https://orcid.org/0000-0001-6378-2837","contributorId":897,"corporation":false,"usgs":true,"family":"Kelly","given":"Brian","email":"bkelly@usgs.gov","middleInitial":"P.","affiliations":[{"id":353,"text":"Kansas Water Science Center","active":false,"usgs":true},{"id":396,"text":"Missouri Water Science Center","active":true,"usgs":true}],"preferred":true,"id":539421,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Studley, Seth E. sstudley@usgs.gov","contributorId":5916,"corporation":false,"usgs":true,"family":"Studley","given":"Seth","email":"sstudley@usgs.gov","middleInitial":"E.","affiliations":[{"id":353,"text":"Kansas Water Science Center","active":false,"usgs":true}],"preferred":true,"id":539422,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Commonly used specimens for wildlife disease investigations include intact carcasses, tissues from carcasses, euthanized or moribund animals, parasites, ingested food, feces, or environmental samples. Samples from live animals or the environment (e.g., contaminated feed) in the same vicinity as a mortality event also may be helpful. The type of specimen collected is determined by availability of samples and biological objectives. Multiple fresh, intact carcasses from affected species are the most useful in establishing a cause for a mortality event. Submission of entire carcasses allows observation of gross lesions and abnormalities, as well as disease testing of multiple tissues. Samples from live animals may be more appropriate when sick animals cannot be euthanized (e.g., threatened or endangered species) or for research and monitoring projects examining disease or agents circulating in apparently healthy animals or those not exhibiting clinical signs. Samples from live animals may include collections of blood, hair, feathers, feces, or ectoparasites, or samples obtained by swabbing lesions or orifices. Photographs and videos are useful additions for recording field and clinical signs and conveying conditions at the site. Collection of environmental samples (e.g., feces, water, feed, or soil) may be appropriate when animals cannot be captured for sampling or the disease agent may persist in the environment. If lethal collection is considered necessary, biologists should refer to the policies, procedures, and permit requirements of their institution/facility and the agency responsible for species management (U.S. Fish and Wildlife Service or State natural resource agency) prior to use in the field. If threatened or endangered species are found dead, or there is evidence of illegal take, field personal should contact local wildlife law enforcement authorities immediately and prior to handling the carcass.</p>\n<p>Prior to collecting samples, it is important to determine the capabilities and submission criteria of the laboratory receiving the samples. Some laboratories may specialize in a limited number of tests, be equipped to accept only certain types of tissues (instead of entire carcasses), or specialize in particular species or group of animals (e.g., reptiles, birds, mammals). Diagnostic laboratories have specific requirements regarding preparation, labeling, and shipping of samples. Adherence to these requirements helps ensure the usefulness of any submitted specimens. Although laboratories may vary in the cost and turnaround times for diagnostic tests, some laboratories may be able to prioritize samples and accommodate accelerated time frames if communicated at the time of submission. Keeping a prepacked kit with basic carcass-collection supplies, including a paper copy of the specimen history form (available for download from the Web sites of most diagnostic laboratories), in the office or vehicle will decrease the chances of forgetting an essential item and decrease response time for arriving at an event.</p>","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"Section C: Techniques in disease surveillance and investigation in Book 15: <i>Field Manual of Wildlife Diseases</i>","largerWorkSubtype":{"id":5,"text":"USGS Numbered Series"},"language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/tm15C4","usgsCitation":"White, C.L., and Dusek, R., 2015, Wildlife specimen collection, preservation, and shipment: U.S. Geological Survey Techniques and Methods 15-C4, iv, 23 p., https://doi.org/10.3133/tm15C4.","productDescription":"iv, 23 p.","numberOfPages":"32","onlineOnly":"Y","additionalOnlineFiles":"N","ipdsId":"IP-056839","costCenters":[{"id":456,"text":"National Wildlife Health Center","active":true,"usgs":true}],"links":[{"id":297583,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/tm15C4.jpg"},{"id":297582,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/tm/15/c04/pdf/tm15-c4.pdf","size":"1.19 MB","linkFileType":{"id":1,"text":"pdf"}},{"id":297557,"rank":1,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/tm/15/c04/"}],"publicComments":"This report is Chapter 4 of Section C: Techniques in disease surveillance and investigation in Book 15: <i>Field Manual of Wildlife Diseases</i>","publishingServiceCenter":{"id":6,"text":"Columbus PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"54dd2ad1e4b08de9379b3222","contributors":{"editors":[{"text":"Franson, J.

The expansiveness of the Everglades, limited number of gaging stations, and extreme sensitivity of the ecosystem to small changes in water depth have created a need for accurate water-level and water-depth maps. The EDEN water-surface elevation model uses data from approximately 240 gages in the Everglades to create daily continuous interpolations of the water-surface elevation and water depth for the freshwater portion of the Everglades from 2000 to the present (2014). These maps provide hydrologic data previously unavailable for assessing biological and ecological studies.</p>\n<p>Ecologists working in the Everglades expressed a need to the EDEN project team for daily EDEN water-level surfaces from 1990 to 1999. The additional 10 years of surfaces will provide ecologists and resource managers with two decades (1991&ndash;2011) of surfaces to analyze hydrologic dynamics. Before 2000, many of the EDEN gages used to generate water surfaces were not in operation. These datasets were extended to provide estimations of hydrologic time-series histories. The general approach to the record extension (hindcasts) was to (1) create a database of available data from 1990 to the present; (2) use dynamic cluster analysis to group stations with similar hydrologic behaviors for subareas of the Everglades with a large number of stations; (3) use results from the cluster analysis to select candidate explanatory variables; (4) develop linear regression or artificial neural network models to extend water-level records; and (5) evaluate record extensions by using model performance statistics and comparison of water-surface maps for similar hydrologic conditions for the hindcasted period (1991&ndash;99) and measured period (2000&ndash;11).</p>\n<p>To hindcast and fill data records, 214 empirical models were developed&mdash;189 are linear regression models and 25 are artificial neural network models. The coefficient of determination (R<sup>2</sup>) for 163 of the models is greater than 0.80 and the median percent model error (root mean square error divided by the range of the measured data) is 5 percent. To evaluate the performance of the hindcast models as a group, contour maps of modeled water-level surfaces at 2-centimeter (cm) intervals were generated using the hindcasted data. The 2-cm contour maps were examined for selected days to verify that water surfaces from the EDEN model are consistent with the input data. The biweekly 2-cm contour maps did show a higher number of issues during days in 1990 as compared to days after 1990. May 1990 had the lowest water levels in the Everglades of the 21-year dataset used for the hindcasting study. To hindcast these record low conditions in 1990, many of the hindcast models would require large extrapolations beyond the range of the predictive quality of the models. For these reasons, it was decided to limit the hindcasted data to the period January 1, 1991, to December 31, 1999. Overall, the hindcasted and gap-filled data are assumed to provide reasonable estimates of station-specific water-level data for an extended historical period to inform research and natural resource management in the Everglades.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/sir20145226","usgsCitation":"Conrads, P., Petkewich, M.D., O’Reilly, A.M., and Telis, P.A., 2015, Hydrologic record extension of water-level data in the Everglades Depth Estimation Network (EDEN), 1991-99: U.S. Geological Survey Scientific Investigations Report 2014-5226, Report: vi, 27 p.; 2 Tables; 2 Appendixes, https://doi.org/10.3133/sir20145226.","productDescription":"Report: vi, 27 p.; 2 Tables; 2 Appendixes","numberOfPages":"38","onlineOnly":"Y","additionalOnlineFiles":"Y","temporalStart":"1991-01-01","temporalEnd":"1999-12-31","ipdsId":"IP-059254","costCenters":[{"id":13634,"text":"South Atlantic Water Science Center","active":true,"usgs":true}],"links":[{"id":297562,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/sir20145226.jpg"},{"id":297559,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/sir/2014/5226/"},{"id":297560,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/sir/2014/5226/pdf/sir2014-5226.pdf","size":"2.93 MB","linkFileType":{"id":1,"text":"pdf"}},{"id":297561,"type":{"id":7,"text":"Companion Files"},"url":"https://pubs.usgs.gov/sir/2014/5226/downloads/sir2014-5226.xlsx","text":"Table 1 and 3, Appendixes 1-2","size":"149 kB","linkFileType":{"id":3,"text":"xlsx"}}],"projection":"Universal Transverse Mercator projection","country":"United States","state":"Florida","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -81.93328857421875,\n              25.063209244186485\n            ],\n            [\n              -81.93328857421875,\n              26.649913524725044\n            ],\n            [\n              -79.98596191406249,\n              26.649913524725044\n            ],\n            [\n              -79.98596191406249,\n              25.063209244186485\n            ],\n            [\n              -81.93328857421875,\n              25.063209244186485\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","publicComments":"Prepared as part of the U.S. Geological Survey Greater Everglades Priority Ecosystem Science","publishingServiceCenter":{"id":8,"text":"Raleigh PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"54dd2a87e4b08de9379b30d1","contributors":{"authors":[{"text":"Conrads, Paul 0000-0003-0408-4208 pconrads@usgs.gov","orcid":"https://orcid.org/0000-0003-0408-4208","contributorId":764,"corporation":false,"usgs":true,"family":"Conrads","given":"Paul","email":"pconrads@usgs.gov","affiliations":[{"id":559,"text":"South Carolina Water Science Center","active":true,"usgs":true},{"id":13634,"text":"South Atlantic Water Science Center","active":true,"usgs":true}],"preferred":false,"id":539310,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Petkewich, Matthew D. 0000-0002-5749-6356 mdpetkew@usgs.gov","orcid":"https://orcid.org/0000-0002-5749-6356","contributorId":982,"corporation":false,"usgs":true,"family":"Petkewich","given":"Matthew","email":"mdpetkew@usgs.gov","middleInitial":"D.","affiliations":[{"id":559,"text":"South Carolina Water Science Center","active":true,"usgs":true},{"id":13634,"text":"South Atlantic Water Science Center","active":true,"usgs":true}],"preferred":true,"id":539311,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"O’Reilly, Andrew M. 0000-0003-3220-1248 aoreilly@usgs.gov","orcid":"https://orcid.org/0000-0003-3220-1248","contributorId":2184,"corporation":false,"usgs":true,"family":"O’Reilly","given":"Andrew","email":"aoreilly@usgs.gov","middleInitial":"M.","affiliations":[{"id":5051,"text":"FLWSC-Orlando","active":true,"usgs":true}],"preferred":true,"id":539312,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Telis, Pamela A. patelis@usgs.gov","contributorId":1461,"corporation":false,"usgs":true,"family":"Telis","given":"Pamela","email":"patelis@usgs.gov","middleInitial":"A.","affiliations":[{"id":269,"text":"FLWSC-Ft.

As a consequence, model predictions of regional methane emissions based on field campaigns from short eddy covariance towers or static chambers have large uncertainties, because measurements focused on a particular known source of methane emission will be biased compared to regional estimates with regards to magnitude, spatial scale, or frequency of these emissions. Given the relatively large importance of predicting future terrestrial methane fluxes for constraining future atmospheric methane growth rates, a clear need exists to reduce spatiotemporal uncertainties. In 2010, an Ameriflux tower (US-PFa) near Park Falls, WI, USA, was instrumented with closed-path methane flux measurements at 122&nbsp;m above ground in a mixed wetland&ndash;upland landscape representative of the Great Lakes region. Two years of flux observations revealed an average annual methane (CH</span><sub>4</sub><span>) efflux of 785&nbsp;&plusmn;&nbsp;75&nbsp;mg&nbsp;C</span><img src=\"http://cdn.els-cdn.com/sd/entities/sbnd\" border=\"0\" alt=\"single bond\" data-inlimg=\"/entities/sbnd\" data-loaded=\"true\" /><span>CH</span><sub>4</sub><span>&nbsp;m</span><sup>&minus;2</sup><span>&nbsp;yr</span><sup>&minus;1</sup><span>, compared to a mean CO</span><sub>2</sub><span>&nbsp;sink of &minus;80&nbsp;g&nbsp;C</span><img src=\"http://cdn.els-cdn.com/sd/entities/sbnd\" border=\"0\" alt=\"single bond\" data-inlimg=\"/entities/sbnd\" data-loaded=\"true\" /><span>CO</span><sub>2</sub><span>&nbsp;m</span><sup>&minus;2</sup><span>&nbsp;yr</span><sup>&minus;1</sup><span>, a ratio of 1% in magnitude on a mole basis. Interannual variability in methane flux was 30% of the mean flux and driven by suppression of methane emissions during dry conditions in late summer 2012. Though relatively small, the magnitude of the methane source from the very tall tower measurements was mostly within the range previously measured using static chambers at nearby wetlands, but larger than a simple scaling of those fluxes to the tower footprint. Seasonal patterns in methane fluxes were similar to those simulated in the Dynamic Land Ecosystem Model (DLEM), but magnitude depends on model parameterization and input data, especially regarding wetland extent.

As a consequence of flow and temperature changes, the composition and distribution of fish species assemblages are expected to change. In an effort to gain a better understanding of how climatic changes may affect stream temperature, an approach was developed to predict and project daily summertime stream temperature under current and future climate conditions for 94,341 stream kilometers across Wisconsin. The approach uses a combination of static landscape characteristics and dynamic time-series climatic variables as input for an Artificial Neural Network (ANN) Model integrated with a Soil-Water-Balance (SWB) Model. Future climate scenarios are based on output from downscaled General Circulation Models (GCMs). The SWB model provided a means to estimate the temporal variability in groundwater recharge and provided a mechanism to evaluate the effect of changing air temperature and precipitation on groundwater recharge and soil moisture. The Integrated Soil-Water-Balance and Artificial Neural Network version 1 (SWB-ANNv1) Model was used to simulate daily summertime stream temperature under current (1990&ndash;2008) climate and explained 76 percent of the variation in the daily mean based on validation at 67 independent sites. Results were summarized as July mean water temperature, and individual stream segments were classified by thermal class (cold, cold transition, warm transition, and warm) for comparison of current (1990&ndash;2008) with future climate conditions.</p>\n<p>Integrating the SWB Model with the ANN Model provided a mechanism by which downscaled global or regional climate model results could be used to estimate the potential effects of climate change on future stream temperature on a daily time step. To address future climate scenarios, statistically downscaled air temperature and precipitation projections from 10 GCMs and 2 time periods were used with the SWB-ANNv1 Model to project future stream temperature. Projections of future stream temperatures at mid- (2046&ndash;65) and late- (2081&ndash;2100) 21st century showed the July mean water temperature increasing for all stream segments with about 80 percent of stream kilometers increasing by 1 to 2 degrees Celsius (&deg;C) by mid-century and about 99 percent increasing by 1 to 3 &deg;C by late-century. Projected changes in stream temperatures also affected changes in thermal classes with a loss in the total amount of cold-water, cold-transition, and warm-transition thermal habitat and a gain in warm-water and very warm thermal habitat for both mid- and late-21st century time periods. The greatest losses occurred for cold-water streams and the greatest gains for warm-water streams, with a contraction of cold-water streams in the Driftless Area of western and southern Wisconsin and an expansion of warm-water streams across northern Wisconsin. Results of this study suggest that such changes will affect the composition of fish assemblages, with a loss of suitable habitat for cold-water fishes and gain in suitable habitat for warm-water fishes. In the end, these projected changes in thermal habitat attributable to climate may result in a net loss of fisheries, because many warm-water species may be unable to colonize habitats formerly occupied by cold-water species because of other habitat limitations (e.g., stream size, gradient). Although projected stream temperatures may vary greatly, depending on the emissions scenario and models used, the results presented in this report represent one possibility. The relative change in stream temperature can provide useful information for planning for potential climate impacts to aquatic ecosystems. Model results can be used to help identify vulnerabilities of streams to climate change, guide stream surveys and thermal classifications, prioritize the allocation of scarce financial resources, identify approaches to climate adaptation to best protect and enhance resiliency in stream thermal habitat, and provide information to make quantitative assessments of statewide stream resources.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/sir20145186","collaboration":"Prepared in cooperation with the Wisconsin Department of Natural Resources","usgsCitation":"Stewart, J.S., Westenbroek, S.M., Mitro, M.G., Lyons, J.D., Kammel, L.E., and Buchwald, C.A., 2015, A model for evaluating stream temperature response to climate change in Wisconsin: U.S. Geological Survey Scientific Investigations Report 2014-5186, Report: ix, 64 p.;

As a possible eradication method, we evaluated rotenone, a natural piscicide used in fish management and the active ingredient in plants traditionally used by indigenous Hawaiians for capturing fish. To assess rotenone&rsquo;s efficacy in killing tilapia and effects on non-target species, laboratory toxicity tests involved exposing organisms to various concentrations of liquid CFT Legumine (5% rotenone) in static trials of 48-h to 72-h duration.

The 48 h LC50 values for Mozambique tilapia and guppy were 0.06 and 0.11 mg/L rotenone, respectively. Results demonstrate rotenone&rsquo;s potential for non-native fish eradication in brackish-water habitats, with benefit of low mortality to certain macro-invertebrates. High rotenone tolerance displayed by &lsquo;ōpae&rsquo;ula shrimp is noteworthy. Invasive fish are common in anchialine pools, threatening existence of shrimp and other invertebrate fauna.

As a consequence, there remain fundamental questions about what processes initiate and terminate eruptions, and where eruptions begin. Over a one-week period in October 2012, we collected down-hole measurements of pressure and temperature in the conduit of an exceptionally regular geyser (132&nbsp;s/cycle) located in the Chilean desert. We identified four stages in the geyser cycle: (1) recharge of water into the conduit after an eruption, driven by the pressure difference between water in the conduit and in a deeper reservoir; (2) a pre-eruptive stage that follows the recharge and is dominated by addition of steam from below; (3) the eruption, which occurs by rapid boiling of a large mass of water at the top of the water column, and decompression that propagates boiling conditions downward; (4) a relaxation stage during which pressure and temperature decrease until conditions preceding the recharge stage are restored. Eruptions are triggered by the episodic addition of steam coming from depth, suggesting that the dynamics of the eruptions are dominated by geometrical and thermodynamic complexities in the conduit and reservoir. Further evidence favoring the dominance of internal processes in controlling periodicity is also provided by the absence of responses of the geyser to environmental perturbations (air pressure, temperature and probably also Earth tides).</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.jvolgeores.2015.01.002","usgsCitation":"Munoz-Saez, C., Manga, M., Hurwitz, S., Rudolph, M.L., Namiki, A., and Wang, C., 2015, Dynamics within geyser conduits, and sensitivity to environmental perturbations: insights from a periodic geyser in the El Tatio Geyser Field, Atacama Desert, Chile: Journal of Volcanology and Geothermal Research, v. 292, p. 41-55, https://doi.org/10.1016/j.jvolgeores.2015.01.002.","productDescription":"15 p.","startPage":"41","endPage":"55","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-062007","costCenters":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"links":[{"id":472322,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://escholarship.org/content/qt9s61d1cf/qt9s61d1cf.pdf","text":"External Repository"},{"id":297520,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Chile","otherGeospatial":"Atacama Desert","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -70.6201171875,\n              -24.367113562651262\n            ],\n            [\n              -71.630859375,\n              -29.57345707301757\n            ],\n            [\n              -69.6533203125,\n              -29.458731185355315\n            ],\n            [\n              -68.291015625,\n              -24.287026865376422\n            ],\n            [\n              -70.6201171875,\n              -24.367113562651262\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"292","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"54dd2a6ee4b08de9379b305c","contributors":{"authors":[{"text":"Munoz-Saez, Carolina","contributorId":131167,"corporation":false,"usgs":false,"family":"Munoz-Saez","given":"Carolina","affiliations":[{"id":7102,"text":"University of California, Berkeley, Dept. of Civil & Envir.

In contrast exhumed fault zones show solution-transport processes such as pressure solution and contact overgrowths influence fault zone properties . In the absence of fluid flow, overgrowths are driven by gradients in surface curvature where material is dissolved, diffuses, and precipitates at the contact without convergence normal to the contact. To determine the rate of overgrowth for quartz, we conducted single contact experiments in an externally heated pressure vessel. Convergence was continuously monitored using reflected-light interferometry through a long-working-distance microscope. Contact normal force was constant with an initial effective normal stress of 1.7 MPa, temperature was between 350 and 530{degree sign}C, and water pressure was constant at 150 MPa. Two control experiments were conducted: one dry at 425{degree sign}C and one bi-material (sapphire) at 425{degree sign}C and 150 MPa water pressure. No contact growth or convergence was observed in the controls. For wet single-phase contacts, growth was initially rapid and then decreased with time. No convergence was observed. Fluid inclusions indicate that the contact is not uniformly wetted. The contact is bounded by small regions of high aperture, reflecting local free-face dissolution as the source for the overgrowth. The apparent activation energy is ~125 kJ/mol. Extrapolation predicts rates of contact area increase orders of magnitude faster than in dry, room-temperature and hydrothermal friction experiments, suggesting that natural strength recovery near the base of the seismogenic zone could be dominated by contact overgrowth.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1002/2014JB011816","usgsCitation":"Beeler, N.M., and Hickman, S.H., 2015, Direct measurement of asperity contact growth in quartz at hydrothermal conditions: Journal of Geophysical Research B: Solid Earth, v. 120, no. 5, p. 3599-3616, https://doi.org/10.1002/2014JB011816.","productDescription":"18 p.","startPage":"3599","endPage":"3616","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-018602","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":297519,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","volume":"120","issue":"5","noUsgsAuthors":false,"publicationDate":"2015-05-05","publicationStatus":"PW","scienceBaseUri":"54dd2a6be4b08de9379b304c","contributors":{"authors":[{"text":"Beeler, Nicholas M. 0000-0002-3397-8481 nbeeler@usgs.gov","orcid":"https://orcid.org/0000-0002-3397-8481","contributorId":2682,"corporation":false,"usgs":true,"family":"Beeler","given":"Nicholas","email":"nbeeler@usgs.gov","middleInitial":"M.","affiliations":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true},{"id":234,"text":"Earthquake Hazards Program","active":true,"usgs":true}],"preferred":true,"id":539233,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hickman, Stephen H. 0000-0003-2075-9615 hickman@usgs.gov","orcid":"https://orcid.org/0000-0003-2075-9615","contributorId":2705,"corporation":false,"usgs":true,"family":"Hickman","given":"Stephen","email":"hickman@usgs.gov","middleInitial":"H.","affiliations":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true},{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":539234,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Once the highly permeable zones are identified, water-quality data can be collected from each zone to identify whether any of the zones produce water of poor quality.

Sustainable use of this critical water supply requires information about rates of recharge to karst aquifers. The overall goal of this project is to collect long-term, high-resolution hydrologic and geochemical datasets at James Cave, Virginia, to evaluate the quantity and quality of recharge to the karst system. To achieve this goal, the cave has been instrumented for continuous (10-min interval) measurement of the (1) temperature and rate of precipitation; (2) temperature, specific conductance, and rate of epikarst dripwater; (3) temperature of the cave air; and (4) temperature, conductivity, and discharge of the cave stream. Instrumentation has also been installed to collect both composite and grab samples of precipitation, soil water, the cave stream, and dripwater for geochemical analysis. This chapter provides detailed information about the instrumentation, data processing, and data management; shows examples of collected datasets; and discusses recommendations for other researchers interested in hydrologic and geochemical monitoring of cave systems. Results from the research, briefly described here and discussed in more detail in other publications, document a strong seasonality of the start of the recharge season, the extent of the recharge season, and the geochemistry of recharge.</span></p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Advances in watershed science and assessment","language":"English","publisher":"Springer International Publishing","doi":"10.1007/978-3-319-14212-8_8","usgsCitation":"Schreiber, M.E., Schwartz, B.F., Orndorff, W., Doctor, D.H., Eagle, S.D., and Gerst, J.D., 2015, Instrumenting caves to collect hydrologic and geochemical data: case study from James Cave, Virginia, chap. <i>of</i> Advances in watershed science and assessment, p. 205-231, https://doi.org/10.1007/978-3-319-14212-8_8.","productDescription":"27 p.

Assessing the impact of LULC and climate changes on streamflow is typically done with a calibrated and validated watershed model. However, there is a debate on the degree of calibration required. The objective of this study was to quantify the variation in estimated relative and absolute changes in streamflow associated with LULC and climate changes with different calibration approaches. The Soil and Water Assessment Tool (SWAT) was applied in an uncalibrated (UC), single outlet calibrated (OC), and spatially-calibrated (SC) mode to compare the relative and absolute changes in streamflow at 14 gaging stations within the Santa Cruz River Watershed in southern Arizona, USA. For this purpose, the effect of 3 LULC, 3 precipitation (P), and 3 temperature (T) scenarios were tested individually. For the validation period, Percent Bias (PBIAS) values were &gt;100% with the UC model for all gages, the values were between 0% and 100% with the OC model and within 20% with the SC model. Changes in streamflow predicted with the UC and OC models were compared with those of the SC model. This approach implicitly assumes that the SC model is &ldquo;ideal&rdquo;. Results indicated that the magnitude of both absolute and relative changes in streamflow due to LULC predicted with the UC and OC results were different than those of the SC model. The magnitude of absolute changes predicted with the UC and SC models due to climate change (both P and T) were also significantly different, but were not different for OC and SC models. Results clearly indicated that relative changes due to climate change predicted with the UC and OC were not significantly different than that predicted with the SC models. This result suggests that it is important to calibrate the model spatially to analyze the effect of LULC change but not as important for analyzing the relative change in streamflow due to climate change. This study also indicated that model calibration in not necessary to determine the direction of change in streamflow due to LULC and climate change.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.jhydrol.2015.01.007","usgsCitation":"Niraula, R., Meixner, T., and Norman, L.M., 2015, Determining the importance of model calibration for forecasting absolute/relative changes in streamflow from LULC and climate changes: Journal of Hydrology, v. 522, p. 439-451, https://doi.org/10.1016/j.jhydrol.2015.01.007.","productDescription":"13 p.","startPage":"439","endPage":"451","numberOfPages":"13","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-053331","costCenters":[{"id":657,"text":"Western Geographic Science Center","active":true,"usgs":true}],"links":[{"id":297498,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Mexico, United States","otherGeospatial":"Santa Cruz River Watershed","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -111.29150390625,\n              30.93992433102347\n            ],\n            [\n              -111.29150390625,\n              33.22030778968541\n            ],\n            [\n              -109.852294921875,\n              33.22030778968541\n            ],\n            [\n              -109.852294921875,\n              30.93992433102347\n            ],\n            [\n              -111.29150390625,\n              30.93992433102347\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"522","publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"54dd2a67e4b08de9379b303f","contributors":{"authors":[{"text":"Niraula, Rewati","contributorId":100714,"corporation":false,"usgs":false,"family":"Niraula","given":"Rewati","email":"","affiliations":[{"id":7042,"text":"University of Arizona","active":true,"usgs":false}],"preferred":false,"id":539204,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Meixner, Thomas","contributorId":22653,"corporation":false,"usgs":false,"family":"Meixner","given":"Thomas","email":"","affiliations":[{"id":7042,"text":"University of Arizona","active":true,"usgs":false}],"preferred":false,"id":539205,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Norman, Laura M. 0000-0002-3696-8406 lnorman@usgs.gov","orcid":"https://orcid.org/0000-0002-3696-8406","contributorId":967,"corporation":false,"usgs":true,"family":"Norman","given":"Laura","email":"lnorman@usgs.gov","middleInitial":"M.","affiliations":[{"id":657,"text":"Western Geographic Science Center","active":true,"usgs":true}],"preferred":true,"id":539206,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Total nitrogen concentrations in the recent sediment (since about 1970) were variable with no consistent trend indicated.

Elevated concentrations of cadmium, copper, lead, mercury, and zinc in the recent sediment, compared to the predevelopment sediment, indicated likely human-related contamination; however, the trace-element concentrations were less than probable-effects guidelines (available for nine trace elements), which represent the concentrations above which toxic aquatic biological effects usually or frequently occur. Arsenic concentrations typically exceeded the threshold-effects guideline, which represents the concentration above which toxic aquatic biological effects occasionally occur, in the recent and predevelopment sediment. The arsenic likely originated from natural sources.

The phased removal of two large dams on the Elwha River, Washington, exposed 21&nbsp;&plusmn;&nbsp;3&nbsp;million&nbsp;m</span><sup>3</sup><span>, or ~&nbsp;30&nbsp;million&nbsp;tonnes (t), of sediment that had been deposited in the two former reservoirs, allowing a comprehensive investigation of watershed and coastal responses to a substantial increase in sediment supply. Here we provide a source-to-sink sediment budget of this sediment release during the first two years of the project (September 2011&ndash;September 2013) and synthesize the geomorphic changes that occurred to downstream fluvial and coastal landforms. Owing to the phased removal of each dam, the release of sediment to the river was a function of the amount of dam structure removed, the progradation of reservoir delta sediments, exposure of more cohesive lakebed sediment, and the hydrologic conditions of the river. The greatest downstream geomorphic effects were observed after water bodies of both reservoirs were fully drained and fine (silt and clay) and coarse (sand and gravel) sediments were spilling past the former dam sites. After both dams were spilling fine and coarse sediments, river suspended-sediment concentrations were commonly several thousand mg/L with ~&nbsp;50% sand during moderate and high river flow. At the same time, a sand and gravel sediment wave dispersed down the river channel, filling channel pools and floodplain channels, aggrading much of the river channel by ~&nbsp;1&nbsp;m, reducing river channel sediment grain sizes by ~&nbsp;16-fold, and depositing ~&nbsp;2.2&nbsp;million&nbsp;m</span><sup>3</sup><span>&nbsp;of sand and gravel on the seafloor offshore of the river mouth. The total sediment budget during the first two years revealed that the vast majority (~&nbsp;90%) of the sediment released from the former reservoirs to the river passed through the fluvial system and was discharged to the coastal waters, where slightly less than half of the sediment was deposited in the river-mouth delta. Although most of the measured fluvial and coastal deposition was sand-sized and coarser (&gt;&nbsp;0.063&nbsp;mm), significant mud deposition was observed in and around the mainstem river channel and on the seafloor. Woody debris, ranging from millimeter-size particles to old-growth trees and stumps, was also introduced to fluvial and coastal landforms during the dam removals. At the end of our two-year study, Elwha Dam was completely removed, Glines Canyon Dam had been 75% removed (full removal was completed 2014), and ~&nbsp;65% of the combined reservoir sediment masses&mdash;including ~&nbsp;8&nbsp;Mt of fine-grained and ~&nbsp;12&nbsp;Mt of coarse-grained sediment&mdash;remained within the former reservoirs. Reservoir sediment will continue to be released to the Elwha River following our two-year study owing to a ~&nbsp;16&nbsp;m base level drop during the final removal of Glines Canyon Dam and to erosion from floods with larger magnitudes than occurred during our study. Comparisons with a geomorphic synthesis of small dam removals suggest that the rate of sediment erosion as a percent of storage was greater in the Elwha River during the first two years of the project than in the other systems. Comparisons with other Pacific Northwest dam removals suggest that these steep, high-energy rivers have enough stream power to export volumes of sediment deposited over several decades in only months to a few years. These results should assist with predicting and characterizing landscape responses to future dam removals and other perturbations to fluvial and coastal sediment budgets.</span></p>","language":"English","publisher":"Elsevier","publisherLocation":"New York, NY","doi":"10.1016/j.geomorph.2015.01.010","usgsCitation":"Warrick, J., Bountry, J.A., East, A., Magirl,
