Flow-adjusted trends in concentration (the trends that would have occurred in the absence of natural changes in streamflow) and non-flow-adjusted trends in concentration (the overall trends resulting from natural and human factors) were determined. In the analysis of flow-adjusted trends, the removal of streamflow as a variable affecting concentration allowed trends caused by other factors such as implementation of best management practices to be identified. In the analysis of non-flow-adjusted trends, the inclusion of any and all factors affecting concentration allowed trends affecting aquatic ecosystems and the status of streams relative to water-quality standards to be identified. Relations between the flow-adjusted and non-flow-adjusted trends and changes in streamflow, nutrient sources, ground-water inputs, and implementation of management practices also were examined to determine the major factors affecting the trends.\r\n\r\nFrom 1993 to 2003, widespread downward trends in streamflow indicated that drought conditions from about 2000 to 2003 led to decreasing streamflow throughout much of the Missouri River Basin. Flow-adjusted trends in nitrite plus nitrate and ammonia concentrations were split nearly equally between nonsignificant and downward; at about one-half of the sites, management practices likely were contributing to measurable decreases in concentrations of nitrite plus nitrate and ammonia. Management practices had less of an effect on concentrations of total nitrogen; downward flow-adjusted trends in total nitrogen concentrations occurred at only 2 of 19 sites. The pattern of non-flow-adjusted trends in nitrite plus nitrate concentrations was similar to the pattern of flow-adjusted trends; non-flow-adjusted trends were split nearly equally between nonsignificant and downward. A substantial source of nitrite plus nitrate to these streams likely was ground water; because of the time required for ground water to travel to streams, there may have been a lag time between the implementation of some pollution-control strategies and improvement in stream quality, contributing to the nonsignificant trends in nitrite plus nitrate. There were more sites with downward non-flow-adjusted trends than flow-adjusted trends in both ammonia and total nitrogen concentrations, possibly a result of decreased surface runoff from nonpoint sources associated with the downward trends in streamflow. No strong relations between any of the nitrogen trends and changes in nutrient sources or landscape characteristics were identified.\r\n\r\nAlthough there were very few upward trends in nitrogen from 1993 to 2003, there were upward flow-adjusted trends in total phosphorus concentrations at nearly one-half of the sites. At these sites, not only were pollution-control strategies not contributing to measurable decreases in total phosphorus concentrations, there was likely an increase in phosphorus loading on the land surface. There were fewer upward non-flow-adjusted than flow-adjusted trends in total phosphorus concentrations; at the majority of sites, overall total phosphorus concentrations did not change significantly during this period. The preponderance of upward flow-adjusted trends and nonsignificant non-flow-adjusted trends indicates that in some areas of the Missouri River Basin, overall concentrations of total phosphorus would have been higher without the decrease in streamflow and the associated decrease in surface runoff during the study period. During the study period, phosphorus loads from fertilizer generally increased at over one-half of the sites in the basin. Upward flow-adjusted trends were related to increasing fertilizer use in the upstream drainage area, particularly in the 10 percent ","language":"ENGLISH","doi":"10.3133/sir20065231","usgsCitation":"Sprague, L.A., Clark, M.L., Rus, D.L., Zelt, R.B., Flynn, J.L., and Davis, J., 2007, Nutrient and Suspended-Sediment Trends in the Missouri River Basin, 1993-2003: U.S. Geological Survey Scientific Investigations Report 2006-5231, viii, 80 p., https://doi.org/10.3133/sir20065231.","productDescription":"viii, 80 p.","numberOfPages":"88","temporalStart":"1993-01-01","temporalEnd":"2003-01-01","costCenters":[{"id":451,"text":"National Water Quality Assessment Program","active":true,"usgs":true}],"links":[{"id":195512,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":9189,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/sir/2006/5231/","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b32e4b07f02db6b47f4","contributors":{"authors":[{"text":"Sprague, Lori A. 0000-0003-2832-6662 lsprague@usgs.gov","orcid":"https://orcid.org/0000-0003-2832-6662","contributorId":726,"corporation":false,"usgs":true,"family":"Sprague","given":"Lori","email":"lsprague@usgs.gov","middleInitial":"A.","affiliations":[{"id":509,"text":"Office of the Associate Director for Water","active":true,"usgs":true},{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true},{"id":27111,"text":"National Water Quality Program","active":true,"usgs":true},{"id":451,"text":"National Water Quality Assessment Program","active":true,"usgs":true}],"preferred":true,"id":290252,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Clark, Melanie L. mlclark@usgs.gov","contributorId":1827,"corporation":false,"usgs":true,"family":"Clark","given":"Melanie","email":"mlclark@usgs.gov","middleInitial":"L.","affiliations":[{"id":5050,"text":"WY-MT Water Science Center","active":true,"usgs":true}],"preferred":true,"id":290254,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Rus, David L. 0000-0003-3538-7826 dlrus@usgs.gov","orcid":"https://orcid.org/0000-0003-3538-7826","contributorId":881,"corporation":false,"usgs":true,"family":"Rus","given":"David","email":"dlrus@usgs.gov","middleInitial":"L.","affiliations":[{"id":464,"text":"Nebraska Water Science Center","active":true,"usgs":true}],"preferred":true,"id":290253,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Zelt, Ronald B. 0000-0001-9024-855X rbzelt@usgs.gov","orcid":"https://orcid.org/0000-0001-9024-855X","contributorId":300,"corporation":false,"usgs":true,"family":"Zelt","given":"Ronald","email":"rbzelt@usgs.gov","middleInitial":"B.","affiliations":[{"id":464,"text":"Nebraska Water Science Center","active":true,"usgs":true},{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":true,"id":290251,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Flynn, Jennifer L.","contributorId":66298,"corporation":false,"usgs":true,"family":"Flynn","given":"Jennifer","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":290256,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Davis, Jerri V. jdavis@usgs.gov","contributorId":2667,"corporation":false,"usgs":true,"family":"Davis","given":"Jerri V.","email":"jdavis@usgs.gov","affiliations":[{"id":396,"text":"Missouri Water Science Center","active":true,"usgs":true}],"preferred":false,"id":290255,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

The C aquifer occurs mainly in the eastern and southern parts of the 10,300-square-mile Coconino Plateau study area, and the Redwall-Muav aquifer underlies the entire study area. The C aquifer is a water-table aquifer for most of its occurrence with depths to water that range from a few hundred feet to more than 1,500 feet. In the western part of the Coconino Plateau study area, the C aquifer is dry except for small localized perched water-bearing zones decoupled from the C aquifer to the east. The Redwall-Muav aquifer underlies the C aquifer and ranges from at least 3,000 feet below land surface in the western part of the Coconino Plateau study area to more than 3,200 feet below land surface in the eastern part of the study area. The Redwall-Muav aquifer is a confined aquifer for most of its occurrence with hydraulic heads of several hundred to more than 500 feet above the top of the aquifer in the western part of the study area and more than 2,000 feet above the top of the aquifer in the eastern part of the study area near Flagstaff. In the eastern and northeast parts of the area, the C aquifer and the Redwall-Muav aquifer are in partial hydraulic connection through faults and other fractures. The water discharging from the two aquifers on the Coconino Plateau study area is generally of good quality for most intended uses. Water from sites in the lower Little Colorado River Canyon had high concentrations of most trace elements relative to other springs, rivers, and streams in the study area. Concentrations of barium, arsenic, uranium, and lead, and gross alpha radioactivity were greater than U.S. Environmental Protection Agency Maximum Contaminant Levels for drinking water at some sites. Ground water discharging to most springs, streams, and wells on the Coconino Plateau and in adjacent areas is a calcium magnesium bicarbonate type and has low concentrations of the major dissolved constituents. Ground water discharging from the Redwall-Muav aquifer to springs in the lower Little Colorado River Canyon is a mixture of water from the C aquifer and the Redwall-Muav aquifer and is a sodium chloride type with high concentrations of most major dissolved constituents. Concentrations of sulfate and chloride in ground water discharging from the Redwall-Muav aquifer at springs near the south rim of Grand Canyon increase toward the west. Water samples from the Verde River above Mormon Pocket had higher concentrations of most dissolved constituents than samples from springs that discharge from the Redwall-Muav aquifer at Mormon Pocket and in Sycamore Canyon. Water-chemistry data from C aquifer wells and springs in the Flagstaff area indicate that ground-water ages in the aquifer range from 7,000 years to modern and that samples were a mix of younger and older waters. Ground-water ages for the Redwall-Muav aquifer are estimated to range from 22,600 to 7,500 years, and low tritium values indicate that this water is older than water discharging from the C aquifer. Tritium and carbon-14 results indicate that ground water discharging at most springs and streams is a mixture of young and old ground waters, likely resulting from multiple flow paths and multiple recharge areas. Ground-water withdrawals in the study area increased from about 4,000 acre-feet per year prior to 1975, to about 20,000 acre-feet per year in 2003. About two-thirds of the water withdrawn is from the C aquifer and about one-third is from the Redwall-Muav aquifer. In the study area, most development of the C aquifer has occurred near Flagstaff. Development of the Redwall-Muav aquifer is more extensive in Verde Valley where water-bearing zones of the aquifer are closer to land surface. In recent years, however, development of the Redwall-Muav aquifer in the study area has increased in response to population growth and the atten</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/sir20055222","collaboration":"Prepared in cooperation with the Arizona Department of Water Resources","usgsCitation":"Bills, D., Flynn, M., and Monroe, S.A., 2007, Hydrogeology of the Coconino Plateau and adjacent areas, Coconino and Yavapai Counties, Arizona (Version 1.0: Originally posted 2007; Version 1.1: March 2016): U.S. Geological Survey Scientific Investigations Report 2005-5222, Report: xi, 101 p.; 4 Plates: 30.88 x 31.88 inches or smaller, https://doi.org/10.3133/sir20055222.","productDescription":"Report: xi, 101 p.; 4 Plates: 30.88 x 31.88 inches or smaller","numberOfPages":"107","onlineOnly":"Y","additionalOnlineFiles":"Y","costCenters":[{"id":128,"text":"Arizona Water Science Center","active":true,"usgs":true}],"links":[{"id":318944,"rank":3,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/sir/2005/5222/sir2005-5222_text.pdf","text":"Report","size":"7.9 MB","linkFileType":{"id":1,"text":"pdf"},"description":"SIR 2015-5222 Report"},{"id":318945,"rank":4,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/sir/2005/5222/sir2005-5222_plate1.pdf","text":"Plate 1","size":"9.2 MB","linkFileType":{"id":1,"text":"pdf"},"description":"SIR 2005-5222 Plate 1"},{"id":9173,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/sir/2005/5222/","linkFileType":{"id":5,"text":"html"}},{"id":318946,"rank":5,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/sir/2005/5222/sir2005-5222_plate2.pdf","text":"Plate 2","size":"18.2 MB","linkFileType":{"id":1,"text":"pdf"},"description":"SIR 2005-5222 Plate 2"},{"id":318947,"rank":6,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/sir/2005/5222/sir2005-5222_plate3.pdf","text":"Plate 3","size":"17.8 MB","linkFileType":{"id":1,"text":"pdf"},"description":"SIR 2005-5222 Plate 3"},{"id":318948,"rank":7,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/sir/2005/5222/sir2005-5222_plate4.pdf","text":"Plate 4","size":"17.8 MB","linkFileType":{"id":1,"text":"pdf"},"description":"SIR 2005-5222 Plate 4"},{"id":318949,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/sir/2005/5222/coverthb.jpg"}],"geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -113.25,34.5 ], [ -113.25,36.75 ], [ -111,36.75 ], [ -111,34.5 ], [ -113.25,34.5 ] ] ] } } ] }","edition":"Version 1.0: Originally posted 2007; Version 1.1: March 2016","contact":"<p><a href=\"mailto:dc_az@usgs.gov\">Director</a>, Arizona Water Science Center<br /> U.S. Geological Survey<br /> 520 N.

One composite total petroleum system (TPS) was defined for this assessment; it extends from Libya westward into adjacent parts of Algeria and southern Tunisia. The Hamra Basin part of the TPS was subdivided into four assessment units for the purpose of resource assessment. The assessment units cover only 172,390 square kilometers of the Hamra Basin Province; the remaining area has little potential for undiscovered petroleum resources because of the absence of petroleum source rocks.\r\n\r\nUsing a geology-based assessment methodology, the U.S. Geological Survey estimated mean volumes of 784 million barrels of crude oil, 4,748 billion cubic feet of natural gas, and 381 million barrels of natural gas liquids in the Hamra Basin of northwestern Libya. Most of the undiscovered crude oil and natural gas are interpreted to be in deeper parts of the Hamra Basin.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/fs20063140","usgsCitation":"Water Resources Division, U.S. Geological Survey, 2007, U.S. Geological Survey Assessment of Undiscovered Petroleum Resources of the Hamra Basin, Libya, 2006 (Version 1.0): U.S. Geological Survey Fact Sheet 2006-3140, 2 p., https://doi.org/10.3133/fs20063140.","productDescription":"2 p.","numberOfPages":"2","temporalStart":"2006-01-01","temporalEnd":"2006-12-31","costCenters":[{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true}],"links":[{"id":9169,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/fs/2006/3140/","linkFileType":{"id":5,"text":"html"}},{"id":125016,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/fs_2006_3140.jpg"}],"edition":"Version 1.0","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a2be4b07f02db6133d5","contributors":{"authors":[{"text":"Water Resources Division, U.S. Geological Survey","contributorId":128075,"corporation":true,"usgs":false,"organization":"Water Resources Division, U.S. Geological Survey","id":534835,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

This study uses organic carbon (Corg) and trace-element proxies for anoxia and productivity, namely elevated concentrations and accumulation rates of molybdenum and cadmium, in these laminated sediments to suggest that productivity may be more important than ventilation in producing changes in bottom-water oxygen (BWO) conditions on open, highly productive continental margins. The main conclusion from these proxies is that during the last glacial interval (LGI; 24–15</span><span>&nbsp;</span><span>cal</span><span>&nbsp;</span><span>ka) and the Younger Dryas cold interval (YD; 13–11.6</span><span>&nbsp;</span><span>cal</span><span>&nbsp;</span><span>ka) productivity was lower and BWO levels were higher than during OIS3, the B/A, and the Holocene on all margins of the Californias. The Corg and trace-element profiles in the LGI–B/A–Holocene transition in the Cariaco Basin on the margin of northern Venezuela are remarkably similar to those in the transition on the northern California margin. Correlation between D–O cycles in Greenland ice with gray-scale measurements in varved sediments in the Cariaco Basin also is well established. Synchronous climate-driven changes as recorded in the sediments on the margins of the Californias, sediments from the Cariaco Basin, and in the GISP-2 Greenland ice core support the hypothesis that changes in atmospheric dynamics played a major role in abrupt climate change during the last 60</span><span>&nbsp;</span><span>ka. Millennial-scale cycles in productivity and oxygen depletion on the margins of the Californias demonstrate that the California Current System was poised at a threshold whereby perturbations of atmospheric circulation produced rapid changes in circulation in the eastern North Pacific Ocean. It is likely that the Pacific and Atlantic Oceans were linked through the atmosphere. Warmer air temperatures during interstadials would have strengthened Hadley and Walker circulations, which, in turn, would have strengthened the subtropical high pressure systems in both the North Pacific and the North Atlantic, producing increased rainfall over the Cariaco Basin and increased upwelling along the margins of the Californias.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.quascirev.2006.08.006","usgsCitation":"Dean, W.E., 2007, Sediment geochemical records of productivity and oxygen depletion along the margin of western North America during the past 60,000 years: Teleconnections with Greenland Ice and the Cariaco Basin: Quaternary Science Reviews, v. 26, no. 1-2, p. 98-114, https://doi.org/10.1016/j.quascirev.2006.08.006.","productDescription":"17 p.","startPage":"98","endPage":"114","costCenters":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"links":[{"id":371055,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"Continental margin of California","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -123.22265625000001,\n              41.86956082699455\n            ],\n            [\n              -125.3759765625,\n              41.672911819602085\n            ],\n            [\n              -123.92578125,\n              38.44498466889473\n            ],\n            [\n              -121.81640624999999,\n              34.92197103616377\n            ],\n            [\n              -118.0810546875,\n              32.54681317351514\n            ],\n            [\n              -116.54296874999999,\n              32.91648534731439\n            ],\n            [\n              -119.83886718750001,\n              35.496456056584165\n            ],\n            [\n              -121.55273437499999,\n              37.405073750176925\n            ],\n            [\n              -122.958984375,\n              39.67337039176558\n            ],\n            [\n              -123.57421875,\n              40.78054143186033\n            ],\n            [\n              -123.22265625000001,\n              41.86956082699455\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"26","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Dean, Walter E. dean@usgs.gov","contributorId":1801,"corporation":false,"usgs":true,"family":"Dean","given":"Walter","email":"dean@usgs.gov","middleInitial":"E.","affiliations":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"preferred":true,"id":779094,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Within 45 seconds of the start of the earthquake, a 1.2-km-long section of waterfront began sliding seaward, and soon after, ~6-8-m high waves inundated the town. Studies soon after the earthquake concluded that submarine landslides along the Seward waterfront generated the tsunamis that occurred immediately after the earthquake. We analyze pre- and post-earthquake bathymetry data to assess the location and extent of submarine mass failures and sediment transport. New NOAA multibeam bathymetry shows the morphology of the entire fjord at 15 m resolution. We also assembled all older soundings from smooth sheets for comparison to the multibeam dataset. We gridded the sounding data, applied corrections for coseismic subsidence, post-seismic rebound, unrecovered co-seismic subsidence, sea-level rise (vertical datum shift), and measurement errors. The difference grids show changes resulting from the 1964 earthquake. We estimate the total volume of slide material to be about 211 million m3. Most of this material was transported to a deep, flat area, which we refer to as &ldquo;the bathtub&rdquo;, about 6 to 13 km south of Seward. Sub-bottom profiling of the bathtub shows an acoustically transparent unit, which we interpret as a sediment flow deposit resulting from the submarine landslides. The scale of the submarine landslides and the distance over which sediment was transported is much larger than previously appreciated.</p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Submarine mass movements and their consequences","largerWorkSubtype":{"id":15,"text":"Monograph"},"language":"English","publisher":"Springer","doi":"10.1007/978-1-4020-6512-5_28","usgsCitation":"Haeussler, P.J., Lee, H., Ryan, H.F., Labay, K., Kayen, R.E., Hampton, M.A., and Suleimani, E., 2007, Submarine slope failures near Seward, Alaska, during the M9.2 1964 earthquake, chap. <i>of</i> Submarine mass movements and their consequences, v. 27, p. 269-278, https://doi.org/10.1007/978-1-4020-6512-5_28.","productDescription":"10 p.","startPage":"269","endPage":"278","numberOfPages":"10","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true}],"links":[{"id":292219,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","city":"Seward","otherGeospatial":"Resurrection Bay","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -149.50043577610558,\n              60.13841562583016\n            ],\n            [\n              -149.50043577610558,\n              59.9348510334695\n            ],\n            [\n              -149.27006326363548,\n              59.9348510334695\n            ],\n            [\n              -149.27006326363548,\n              60.13841562583016\n            ],\n            [\n              -149.50043577610558,\n              60.13841562583016\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"27","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53edcd52e4b0f61b386d2486","contributors":{"authors":[{"text":"Haeussler, Peter J. 0000-0002-1503-6247 pheuslr@usgs.gov","orcid":"https://orcid.org/0000-0002-1503-6247","contributorId":503,"corporation":false,"usgs":true,"family":"Haeussler","given":"Peter","email":"pheuslr@usgs.gov","middleInitial":"J.","affiliations":[{"id":119,"text":"Alaska Science Center Geology Minerals","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":498252,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lee, H.J.","contributorId":96693,"corporation":false,"usgs":true,"family":"Lee","given":"H.J.","email":"","affiliations":[],"preferred":false,"id":498254,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Ryan, H.

More than twenty grains of zircon and monazite have been identified in this siltstone and dated by SIMS \nSHRIMP-II. Two age clusters have been recognized for these detrital grains, in the ranges 0.8−1.2 Ga and 1.6−1.8 Ga. \nThe compositions of the rock clasts suggest that the bedrock situated to the west of Lake Vostok is sedimentary.

(2007) examined the spatial relationship between two common shoreline definitions used in shoreline change analysis, mean high water [MHW] derived from lidar data and the wet/dry line digitized from orthophotography. Here, we summarize this work and extend the analysis with a comparison between two different methods of MHW shoreline extraction from liar data: a profile-based method (Stockdon  et al., 2002) and a method based on correction of the lidar data to a MHW datum (Hess et al., 2005). Potential bias generated by using these different shoreline types together can affect not only the accuracy of shoreline change analysis, but also the coastal management policies and decision that rely on it.

The recent surge of interest in deep-sea corals is another example of how focused research on a particular subject can result in new perspectives on continental slope biotopes. Although deep-sea corals have been known for over 200 years, they were viewed as somewhat of a novelty, and research on them was sporadic, typically geologic, and usually only documented their occurrences (e.g., Stetson et al., 1962; Neumann et al., 1977; Paull et al., 2000).","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Oceanography","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"The Oceanography Society","doi":"10.5670/oceanog.2007.13","usgsCitation":"Ross, S., 2007, Unique deep-water ecosystems off the southeastern United States: Oceanography, v. 20, no. 4, p. 130-139, https://doi.org/10.5670/oceanog.2007.13.","productDescription":"9 p.","startPage":"130","endPage":"139","numberOfPages":"9","costCenters":[{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true}],"links":[{"id":476931,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.5670/oceanog.2007.13","text":"Publisher Index Page"},{"id":292465,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":292464,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.5670/oceanog.2007.13"}],"country":"United States","state":"Georgia;Florida;North Carolina;South Carolina","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -80.0,28.0 ], [ -80.0,34.0 ], [ -74.0,34.0 ], [ -74.0,28.0 ], [ -80.0,28.0 ] ] ] } } ] }","volume":"20","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53f25ff5e4b0333418718985","contributors":{"authors":[{"text":"Ross, Steve W.","contributorId":41134,"corporation":false,"usgs":false,"family":"Ross","given":"Steve W.","affiliations":[{"id":32398,"text":"University of North Carolina Wilmington","active":true,"usgs":false}],"preferred":false,"id":498653,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Hydrate of tetrahydrofuran (THF) has long been used for laboratory studies of gas hydrate-bearing sediments to provide close control on hydrate concentrations and to overcome the long formation history of methane hydrate from aqueous phase methane in sediments. Yet differences in the polarizability of THF (polar molecule) compared to methane (nonpolar molecule) raise questions about the suitability of THF as a proxy for methane in the study of hydrate-bearing sediments. From existing data and simple macroscale experiments, we show that despite its polar nature, THF's large molecular size results in low permittivity, prevents it from dissolving precipitated salts, and hinders the solvation of ions on dry mineral surfaces. In addition, the interfacial tension between water and THF hydrate is similar to that between water and methane hydrate. The processes that researchers choose for forming hydrate in sediments in laboratory settings (e.g., from gas, liquid, or ice) and the pore-scale distribution of the hydrate that is produced by each of these processes likely have a more pronounced effect on the measured macroscale properties of hydrate-bearing sediments than do differences between THF and methane hydrates themselves.</p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geochemistry, Geophysics, Geosystems","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","doi":"10.1029/2006GC001531","usgsCitation":"Lee, J., Yun, T., Santamarina, J., and Ruppel, C., 2007, Observations related to tetrahydrofuran and methane hydrates for laboratory studies of hydrate-bearing sediments: Geochemistry, Geophysics, Geosystems, v. 8, no. 6, 10 p., https://doi.org/10.1029/2006GC001531.","productDescription":"10 p.","numberOfPages":"10","costCenters":[{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true}],"links":[{"id":292314,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":292313,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1029/2006GC001531"}],"volume":"8","issue":"6","noUsgsAuthors":false,"publicationDate":"2007-06-06","publicationStatus":"PW","scienceBaseUri":"53ef1ed5e4b0bfa1f993efda","contributors":{"authors":[{"text":"Lee, J.Y.","contributorId":20061,"corporation":false,"usgs":true,"family":"Lee","given":"J.Y.","email":"","affiliations":[],"preferred":false,"id":498389,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Yun, T.S.","contributorId":26141,"corporation":false,"usgs":true,"family":"Yun","given":"T.S.","email":"","affiliations":[],"preferred":false,"id":498390,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Santamarina, J.C.","contributorId":50283,"corporation":false,"usgs":true,"family":"Santamarina","given":"J.C.","email":"","affiliations":[],"preferred":false,"id":498391,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Ruppel, C.","contributorId":82050,"corporation":false,"usgs":true,"family":"Ruppel","given":"C.","email":"","affiliations":[],"preferred":false,"id":498392,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

As a result, a team of scientists from OCNMS, National Centers for Coastal Ocean Science (NCCOS), and other partnering institutions initiated a series of surveys to assess the distribution of deep-sea coral/sponge assemblages within the sanctuary and to look for evidence of potential anthropogenic impacts in these critical habitats. Initial results indicated that remotely delineating areas of hard bottom substrate through acoustic sensing could be a useful tool to increase the efficiency and success of subsequent ROV-based surveys of the associated deep-sea fauna. Accordingly, side scan sonar surveys were conducted in May 2004, June 2005, and April 2006 aboard the NOAA Ship <i>McArthur II</i> to: (1) obtain additional imagery of the seafloor for broader habitat-mapping coverage of sanctuary waters, and (2) help delineate suitable deep-sea coral-sponge habitat, in areas of both high and low commercial-fishing activities, to serve as sites for surveying-in more detail using an ROV on subsequent cruises, Several regions of the sea floor throughout the OCNMS were surveyed and mosaicked at 1-meter pixel resolution. Imagery from the side scan sonar mapping efforts was integrated with other complementary data from a towed camera sled, ROVs, sedentary samples, and bathymetry records to describe geological and biological (where possible) aspects of habitat. Using a hierarchical deep-water marine benthic classification scheme (Greene et al. 1999), we created a preliminary map of various habitat polygon features for use in a geographical information system (GIS).

Studying \nmineralized systems prior to mining allows us to compare \nthe natural biogeochemical signature in mineralized versus \nnonmineralized areas. The resultant data and interpretation \nalso provide a baseline for evaluating what, if any, changes in \nelemental distribution result from development. This report \ninvestigates the chemistry of stream water, streambed sediment, and soil in the context of regional bedrock geology. The \nmajor-ion chemistry of the waters reflects a rock-dominated \naqueous system, and the waters are classified as Ca<sup>2+</sup> and \nMg<sup>2+</sup> - HCO<sub>3</sub><sup>-</sup> to Ca<sup>2+</sup> and Mg<sup>2+</sup> - SO<sub>4</sub><sup>-2</sup> waters. Creeks draining \nthe gneissic lithologies tend to be more sulfate dominated \nthan those draining the intrusive units. Sulfate also dominated \ncreeks draining mineralized areas; however, the underlying \nparagneiss unit could be contributing substantially to the \nsulfate concentration, and the sulfate concentration in these \ncreeks may reflect a complex baltholith-paragneiss boundary rather than mineralization. Arsenic concentrations in \nbed sediments were elevated in mineralized areas relative \nto nonmineralized areas. Elevated concentrations of nickel, \nchromium, iron, manganese, and cobalt appear to reflect \nthe presence of ultramafic rocks in the drainage. In general, aqueous metal concentrations were below the State of \nAlaska’s Aquatic Life Criteria and Drinking Water Standards, \nwith the exception of arsenic in stream water, which ranged \nin concentration from less than 1 to 14 micrograms per liter \n(&mu;g/L) and exceeded the drinking water standard at one site. \nThe arsenic and antimony concentration in the A, B, and C \nsoil horizons ranged from 3 to 410 milligrams per kilogram \n(mg/kg), 6.1 to 440 mg/kg, and 2 to 300 mg/kg, respectively, for arsenic and 0.4 to 24 mg/kg, 0.6 to 25 mg/kg, and 0.2 to \n16 mg/kg, respectively, for antimony. The arsenic and antimony concentrations in stream waters correlate well with the \nconcentrations in soils. However, significantly less arsenic and \nantimony was extracted from C horizon soils in water leaching \nexperiments, indicating that the arsenic and antimony in the \nC horizon is present in a less available form than in the A or \nB horizons. Arsenic and antimony uptake by grayleaf willow \n(Salix glauca L.) appears minimal, with arsenic concentrations ranging from less than 0.01 to 0.14 mg/kg and antimony \nconcentrations ranging from less than 0.003 to 0.23 mg/kg \nin willow leaves. In general, the highest concentrations of \nboth arsenic and antimony in water and soils were found \nnear mineralized areas.

Tampa Bay, one the Gulf of Mexico's largest estuaries, exemplifies the threats that our estuaries face (EPA Report 2001, Tampa Bay Estuary Program-Comprehensive Conservation and Management Plan (TBEP-CCMP)). More than 2 million people live in the Tampa Bay watershed, and the population constitutes to grow. Demand for freshwater resources, conversion of undeveloped areas to resident and industrial uses, increases in storm-water runoff, and increased air pollution from urban and industrial sources are some of the known human activities that impact Tampa Bay. Beginning on 2001, additional anthropogenic modifications began in Tampa Bat including construction of an underwater gas pipeline and a desalinization plant, expansion of existing ports, and increased freshwater withdrawal from three major tributaries to the bay.</p>\n<br>\n<p>In January of 2001, the Tampa Bay Estuary Program (TBEP) and its partners identifies a critical need for participation from the U.S. Geological Survey (USGS) in providing multidisciplinary expertise and a regional-scale, integrated science approach to address complex scientific research issue and critical scientific information gaps that are necessary for continued restoration and preservation of Tampa Bay. Tampa Bay stakeholders identified several critical science gaps for which USGS expertise was needed (Yates et al. 2001). These critical science gaps fall under four topical categories (or system components): 1) water and sediment quality, 2) hydrodynamics, 3) geology and geomorphology, and 4) ecosystem structure and function. Scientists and resource managers participating in Tampa Bay studies recognize that it is no longer sufficient to simply examine each of these estuarine system components individually, Rather, the interrelation among system components must be understood to develop conceptual and predictive modeling tools for effective ecosystem adaptive management. As a multidisciplinary organization, the USGS possesses the capability of developing and coordinating an integrated science strategy for estuarine research founded on partnerships and collaborative efforts, multidisciplinary teams of scientists, and integrated field work, data analysis and interpretation, and product development. The primary role of the USGS in Tamps Bay research was defined with our partners based upon this capability to address estuarine issues using an integrated science approach with a regional perspective and within a national context to complement the numerous ongoing scien efforts by state and local agencies that address local issues within Tamp Bay. Six primary components of the USGS Tamp Bay Study address critical gaps within each of the the four estuarine system components and focus on:</p>\n<br>\n<p>1.) Examining how natural and man-made \nphysical changes affect ecosystem health \nthrough mapping and modeling.</p>\n<p>2.) Identifying sources and quality of \ngroundwater, surface water, and \nsediment,</p>\n<p>3.) Identifying sources and quality of \ngroundwater, surface water, and \nsediment,</p>\n<p>4.) Assessing the natural and man-made \nchanges affecting wetland health and \nrestoration,</p>\n<p>5.) Identifying and measuring the impact of \nurbanization on seafloor habitats,</p>\n<p>Providing a web-based digital \ninformation management system of information for scientists and the public, \nincluding a system that supports the work \nof those officials who must make \ndecisions that affect the state of the bay.</p>\n<br>\n<p>The Tampa Bay Study is in its sixth year and will \ncontinue through September 2007. This paper \npresents a non-inclusive summary of key findings \nassociated with the six primary project \ncomponents listed above.

Stream sediments downstream \nfrom these deposits have high concentrations of arsenic and \nantimony (arsenic median is 1,670 parts per million, maximum is 10,000 parts per million; antimony median is 192 \nparts per million, maximum is 7,200 parts per million). The \nmobility of arsenic and antimony is controlled by the local \nredox environment, with arsenic being less mobile in oxidized \nsurface waters relative to antimony, and arsenic more mobile \nin reduced ground water.

In high-gradient alpine streams, aufeis forms mostly \nas a result of ground-water discharge into the stream channel. \nThe ice occludes this discharge, perturbing the steady-state \ncondition, and causing an incremental rise in the local water \ntable until discharge occurs higher on the stream bank above \nthe previously formed ice. Successive freezing of onlapping \nice layers can lead to aufeis accumulations several meters \nthick.\nThe location and extent of aufeis in high-gradient streams \nmay be useful to relate local hydrology to geologic structure. \nIn the Goodpaster River basin study area, mineral deposits \nare known to occur, the location of which may be structurally \ncontrolled. Therefore, a more thorough understanding of \nregional geologic structures may facilitate a more detailed \nunderstanding of the genesis of the mineral deposits.\nExtensive aufeis was observed during visits to the \nGoodpaster River basin in east-central Alaska during 1999, \n2001, and 2002. Seeps from the sides of the valleys caused \nice to build up, giving the ice surface a concave-upward \nshape perpendicular to the stream direction. This concavity is \nevidence for ground-water discharge along the length of the \naufeis, as opposed to discharge from a single upstream point. \nDuring thaw, streamflow is commonly observed out of the \nnormal channel, evidence that occlusion of the channel (and \nshallow sediments) by ice is a viable mechanism for causing \nthe water table to rise.\nThe thickest (>3 meters) and most extensive aufeis \n(100’s of meters to kilometers along valleys) coincided with \nlocations of laterally extensive (>5 kilometers) mapped \nhigh-angle brittle fault zones, suggesting that the fault zones \nare hydraulically conductive. Additional evidence of water flow is provided by observed changes in stream-water chemistry in reaches in which aufeis forms, despite a lack of \nsurface tributaries. Minor or no aufeis was observed in many \nother drainage valleys where no laterally extensive structures \nhave been mapped, implying that aufeis formation results from \nmore than a topographic effect or discharge from bank storage. \nThus, the presence of thick, laterally extensive aufeis in highgradient streams may be a useful aid to geologic structural \nmapping in arctic and subarctic climates.","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"Recent U.S. Geological Survey studies in the Tintina Gold Province, Alaska, United States, and Yukon, Canada--results of a 5-year project (Scientific Investigations Report 2007-5289)","largerWorkSubtype":{"id":5,"text":"USGS Numbered Series"},"language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/sir20075289F","collaboration":"This report is Chapter F in <i>Recent U.S. Geological Survey studies in the Tintina Gold Province, Alaska, United States, and Yukon, Canada--results of a 5-year project</i>.

The plan, expected to include various alternatives for storm protection and \nerosion mitigation, is referred to as the Fire Island to Montauk Point Reformulation Plan (FIMP). \nThese plans are expected to follow the Corps of Engineers’ Environmental Operating Principles \nstriving for long term environmental sustainability and balance between environmental protection \nand protection of human health and property.</p>\n<br>\n<p>Fire Island National Seashore (FIIS), a 19,579 acre unit of the National Park System includes a 32 \nmile long coastal barrier island located within the FIMP project area. A seven-mile section of the \npark, Otis Pike Fire Island High Dune Wilderness Area, is also a designated Federal Wilderness \nArea. The FIIS includes not only the barrier island and sand dunes, but also several islands, sand \nflats and wetlands landward of the barrier, submerged parts of Great South Bay shoreface, extending \napproximately 4,000 feet into the bay with the inner shelf region extending approximately 1,000 feet \nseaward of the Fire Island shoreline. </p>\n<br>\n<p>The Fire Island barrier islands, a sand-starved system dominated by highly dynamic processes, are \nstruggling to maintain their integrity in the face of sea-level rise and storms. Adding to the dilemma \nis that development on the barriers and the mainland has increased greatly during the past 50 years. \nAs such, managers and decision makers in federal agencies, state agencies and local governments are \nchallenged to balance tradeoffs between protection of lives and property, public access and long \nterm conservation of natural habitats and processes and the plants and animals that depend on these \nhabitats.</p>\n<br>\n<p>National Park Service (NPS) policy stipulates that natural coastal processes be maintained to the greatest extent possible and not be impeded so as to conserve landforms, habitats and natural ecosystem resources that reply on the landforms and processes for long-term sustainability of the national park. Storms and associated processes such as waves, tides, currents and relative sea-level change are critical elements for the formation and evolution of these barrier islands, sand dunes, back-barrier sand flats and lagoons and vegetated wetlands. Processes such as wave run-up, overwash and barrier beaching, which occur during elevated storm surge are all necessary processes in enabling the efficient transfer of sediments, nutrients and marine water from the Atlantic Ocean across barriers and into Great South Bay. A large body of scientific data and information published over the past 50 years shows that such transfers of sediment and water from the ocean to the bays are essential for the long-term maintenance of the barrier island and back-bay systems and their biologically diverse habitats an d ecosystems. Current relative sea-level rise (~12 in/century) is chronic and pervasive in driving Long Island coastal change and with the likelihood of accelerating sea level rise in the near future, coastal hazards such as erosion, inundation, and storm surge flooding will increase, with corresponding increased risk to life and property on both Fire Island and on the mainland.</p>\n<br>\n<p>In addition, the cumulative effects over the past century and more, both direct and indirect, of human impacts on the Long Island coast have altered the barrier beach and dunes and sediment transport processes. These impacts have likely increased the potential for breaching and increased risk to life and property on the coast and the mainland. Examples of direct impacts are: the stone jetties at Moriches, Shinnecock, and Fire Island tidal inlets and groin field structures at Westhampton that alter littoral processes, armoring and erosion-control stabilization of the headlandds such as the Montauk Point headlands, and deepening of navigation channels by dredging through the tidal inlets and in the bays. Indirect impacts that have a bearing on decisions to deal with breaching are: high-risk development of the barrier islands and low-lying areas of the mainland vulnerable to flooding, and the dredging of nearshore sand shoals for beach nourishment.</p>\n<br>\n<p>The NPS strives to employ a coastal management framework for decision making that is based on assessment of the physical and ecological properties of the shoreline as well as human welfare and property. In order to protect developed areas of Fire Island and the mainland from loss of life, flooding, and other economic and physical damage, the NPS will likely need to consider allowing artificial closure of some breaches within the FIIS under certain circumstances. The decision by the NPS to allow breaches to evolve naturally and possibly close or to allow artificially closing breaches is based on four criteria:<p>\n<br>\n<p>1. Volumes of sediment transported landward and exchange of water and nutrients;</p>\n<p>2. Elevated water levels and flooding risk to mainland life and property;</p>\n<p>3. Engineering processes of artificial closure; and</p>\n<p>4. Economic costs and benefits of artificial closure.</p>\n<br>\n<p>This report for breach management presents protocols which specify when breach closures within the FIIS might be desirable and necessary, as well as provides recommendations for structural breach closure engineering operations which are indented to minimize negative impacts to the natural wilderness values and cultural resources within the FIIS, particularly the Otis Pike Wilderness Area. The goal of the plan is to strike a balance between protecting natural resources and allowing natural processes to operate and avoiding loss of life and excessive property damage.</p>","language":"English","publisher":"National Park Service","publisherLocation":"Boston, MA","usgsCitation":"Williams, S.J., and Foley, M.K., 2007, Recommendations for a barrier island breach management plan for Fire Island National Seashore, including the Otis Pike High Dune Wilderness Area, Long Island, New York: Technical Report NPS/NER/NRTR--2007/075, 16 p.","productDescription":"16 p.","costCenters":[{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true},{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":292563,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"New York","otherGeospatial":"Fire Island National Seashore;Long Island;Otis Pike High Dune Wilderness Area","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -73.23551,40.62485 ], [ -73.23551,40.780617 ], [ -72.753194,40.780617 ], [ -72.753194,40.62485 ], [ -73.23551,40.62485 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53f464cee4b073ff773a7d54","contributors":{"authors":[{"text":"Williams, S.
