In turn, sediments and rocks modify wave patterns, affect recreation and tourism, and provide habitat for fish, epifauna, and infauna. Character of the surficial seafloor also influences navigation, commercial and recreational fishing and gathering of other food sources, communication, piplines, national defense, and provides geologic resources including sand and gravel aggregates, minerals, and real or potential energy sources. The beaches, nearshore, and continental margins fall under overlapping levels of managerial responsibility between Federal, State, regional, and local government agencies and consortia. In addition, universities and other academic institutions investigate these places for pure or applied scientific reasons.</p>\n<br>\n<p>Mapping is usually the first step in understanding any issue and is often comprised of remotely gathered geophysical data such as bathymetry and backscatter imagery, and groundtruthing; that is, the collection of physical and virtual samples to tie the remotely gathered data to reality. The physical samples are described and (or) carefully analyzed for grain-size information -- which records both the site's physical conditions and geologic past -- and commonly, for constituent components such as mineral and rock types (to determine onland sources and <i>in situ</i> chemical processes), carbonate and organic content and microfossils (for biological and oceanographic influences), and structure such as layering and bioturbation (for physical influences). The samples may also be subjected to physical tests such as comp[action analyses, liquefaction or plasticity limits, ans other parameters important when considering construction of offshore structures. In recent years, virtual sampling of the seafloor has become popular, through the use of towed video or photographic equipment and the addition of camera to oceanographic equipment such as corers and tripods.</p>\n<br>\n<p>Before about ten years ago, most maps were made by hand. Recently, with the advent of desktop GIS packages, map making and resource analysis can be done nearly \"on-the-fly\" if geographically located data exist. While the problems of projection, scale, and resolution of digitized paper maps are commonly known amongst GIS-users, access to the original underlying point data allows for maps to be regenerated for digital use using statistically proven methods, provides increasing data density by including multiple studies, as well as allows the point data to be used in other ways than just mapping.</p>\n<br>\n<p>These point data may be available in raw or refined or in worded descriptions. Raw data such as granulometric analyses can be manipulated through the use of known equations or empirical relationships to provide information about other parameters of the sediment, such as mean grainsize, sorting, erodability, or rugosity. If refined data are presented such as gravel, sand, and mud percentages, the parameter noted earlier may be estimated. In the case of worded descriptions, values for geologic terms can be assigned, for example, \"fine sand\" equate to 0.2 mm sized particles, to provide numeric terms for GIS or modeling purposes.</p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Proceedings of Coastal Zone '07","largerWorkSubtype":{"id":12,"text":"Conference publication"},"language":"English","publisher":"NOAA Coastal Services Center","publisherLocation":"Charleston, SC","usgsCitation":"Reid, J.A., Williams, S.J., Zimmermann, M., Jenkins, C., and Golden, N., 2007, Integration of seafloor point data in usSEABED, <i>in</i> Proceedings of Coastal Zone '07, 5 p.","productDescription":"5 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":292420,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53f25fe6e4b0333418718924","contributors":{"authors":[{"text":"Reid, Jane A. 0000-0003-1771-3894 jareid@usgs.gov","orcid":"https://orcid.org/0000-0003-1771-3894","contributorId":2826,"corporation":false,"usgs":true,"family":"Reid","given":"Jane","email":"jareid@usgs.gov","middleInitial":"A.","affiliations":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":true,"id":498565,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Williams, S.

It is crucial to understand seasonal changes in beach volume and shape in order to identify areas vulnerable to accelerated erosion. Shepard (1950) was among the first to quantify seasonal beach cycles. Sonu and Van Beek (1971) and Wright et al. (1985) described commonly occurring beach states. Most studies utilize widest spaced 2-D cross shore profiles or shorelines extracted from aerial photographs (e.g. Winant et al. 1975; Aubrey, 1979, Aubrey and Ross, 1985; Larson and Kraus, 1994; Jimenez et al., 1977; Lacey and Peck, 1998; Guillen et al., 1999; Norcorss et al., 2002) to analyzed systematic changes in beach evolution. But with the exception of established field stations, such as Duck, NC (Birkemeier and Mason, 1984), ans Hazaki Oceanographical Research Station (HORS) in Japan (Katoh, 1997), there are very few beach change data sets with high temporal and spatial resolutions (e.g. Dail et al., 2000; Ruggiero et al., 2005; Yates et al., in press). Comprehensive sets of nearshore morphological data and local in situ measurements outside of these field stations are very rare and virtually non-existent high-energy coasts. Studied that have attempted to relate wave statistics to beach morphology change require some knowledge of the nearshore wave climate, and have had limited success using offshore measurement (Sonu and Van Beek, 1971; Dail et al., 2000).</p>\n<br>\n<p>The primary objective of this study is to qualitatively compare spatially variable nearshore wave predictions to beach change measurements in order to understand the processes responsible for a persistent erosion 'hotspot' at Ocean Beach, San Francisco, CA. Local wave measurements are used to calibrate and validate a wave model that provides nearshore wave prediction along the beach. The model is run for thousands of binned offshore wave conditions to help isolate the effects of offshore wave direction and period on nearshore wave predictions. Alongshore varying average beach change statistics are computed at specific profile locations from topographic beach surveys and lidar data.</p>\n<br>\n<p>The study area is located in the San Francisco Bight in central California. Ocean Beach is a seven kilometer long north-south trending sandy coastline located just south of the entrance to the San Francisco Bay Estuary (Figure 1). It contains an erosion hotspot in the southern part of the beach which has resulted in damage to local infrastructure and is the cause of continued concern. A wide range of field data collection and numerical modeling efforts have been focused here as part of the United States Geological Survey's (USGS) San Francisco Bight Coastal Processes Study, which began in October 2003 and represents the first comprehensive study of coastal processes at the mouth of San Francisco Bay.</p>\n<br>\n<p>Ocean Beach is exposed to very strong tidal flows, with measured currents often in excess of 1 m/s at the north end of the beach. Current profiler measurements indicate that current magnitudes are greater in the northern portion of the beach, while wave energy is greater in the southern portion where erosion problems are greatest (Barnard et al., 2007). The sub-aerial beach volume fluctuates seasonally over a maximum envelope of 400,000 m<sup>3</sup> for the seven kilometer stretch (Barnard et al, 2007). The wave climate in the region is dominated by an abundance of low frequency energy (greater than 20 s period) and prevailing northwest incident wave angles. The application of a wave model to the region is further complicated by the presence of the Farallon Islands 40 kilometers west, and a massive ebb tidal delta at the mouth of San Francisco Bay (~150 km<sup>2</sup>), which creates complicated refraction patterns as wave energy moves from offshore Ocean Beach; however the cost and threat of the energetic nearshore environment have limited the temporal and spatial resolution of these measurements. Applying numerical models to predict wave and current patterns along the beach can help supplement the filed data that exists and provide opportunities to make prediction about the impacts of changing environmental forcing.</p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"10th International Workshop on Wind Hindcasting and Forecasting and Coastal Hazard Symposium: North Shore, Oahu, November 11-16, 2007","largerWorkSubtype":{"id":12,"text":"Conference publication"},"language":"English","publisher":"Wave Workshop","usgsCitation":"Eshleman, J.L., Barnard, P., Erikson, L., and Hanes, D.M., 2007, Coupling alongshore variations in wave energy to beach morphologic change using the SWAN wave model at Ocean Beach, San Francisco, CA, <i>in</i> 10th International Workshop on Wind Hindcasting and Forecasting and Coastal Hazard Symposium: North Shore, Oahu, November 11-16, 2007, 20 p.","productDescription":"20 p.","numberOfPages":"20","costCenters":[{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true}],"links":[{"id":292190,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":292189,"type":{"id":15,"text":"Index Page"},"url":"https://www.waveworkshop.org/10thWaves/ProgramFrameset.htm"}],"country":"United States","state":"California","city":"San Francisco","otherGeospatial":"Ocean Beach","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -122.596909,37.693335 ], [ -122.596909,37.929771 ], [ -122.327915,37.929771 ], [ -122.327915,37.693335 ], [ -122.596909,37.693335 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53edcd44e4b0f61b386d23b1","contributors":{"authors":[{"text":"Eshleman, Jodi L.","contributorId":91940,"corporation":false,"usgs":true,"family":"Eshleman","given":"Jodi","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":498175,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Barnard, Patrick L.","contributorId":54936,"corporation":false,"usgs":true,"family":"Barnard","given":"Patrick L.","affiliations":[],"preferred":false,"id":498174,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Erikson, Li H.","contributorId":10880,"corporation":false,"usgs":true,"family":"Erikson","given":"Li H.","affiliations":[],"preferred":false,"id":498173,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hanes, Daniel M.","contributorId":96360,"corporation":false,"usgs":true,"family":"Hanes","given":"Daniel","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":498176,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Although details are still debated there is much evidence from continental and oceanic locations indicating that conditions from 5.3 to about 3.0 Ma were often warmer than in modern times in mid- and high latitudes and that climate variability was subdued compared to the Pleistocene. Millennial-scale early Pliocene climate records are dominated by 19–21 thousand years ago (ka) oscillations.

An example of such a difficulty is the separation of&nbsp;desorption&nbsp;and dissolution processes in releasing contaminants from sediments to groundwaters; very few studies are found in the literature that attempt to quantify contaminant release by these two processes. In this study, the results from several extraction techniques, isotopic exchange experiments, and published spectroscopic studies were combined to estimate the contributions of desorption and dissolution to U(VI) release from contaminated sediments collected from the vadose zone beneath former&nbsp;waste disposal&nbsp;ponds in the Hanford 300-Area (Washington State).&nbsp;Vertical profiles&nbsp;of sediments were collected at four locations from secondary pond surfaces down to, and slightly below, the&nbsp;water table. In three of the four profiles,&nbsp;uraniumconcentration gradients were observed in the sediments, with the highest U concentrations at the top of the profile. One of the vertical profiles contained sediments with U concentrations up to 4.2×10</span><sup>−7</sup><span>&nbsp;</span><span>mol</span><span>&nbsp;</span><span>g</span><sup>−1</sup><span>&nbsp;(100</span><span>&nbsp;</span><span>ppm). U(VI) release to artificial groundwater solutions (AGWs) and extracts from these high-U concentration sediments occurred primarily from dissolution of precipitated U(VI) minerals, including the mineral metatorbernite, [Cu(UO</span><sub>2</sub><span>PO</span><sub>4</sub><span>)</span><sub>2</sub><span>·8H</span><sub>2</sub><span>O]. At the bottom of this profile, beneath the water table, and in all three of the other profiles, U concentrations were &lt;5.88×10</span><sup>−8</sup><span>&nbsp;</span><span>mol</span><span>&nbsp;</span><span>g</span><sup>−1</sup><span>&nbsp;(14</span><span>&nbsp;</span><span>ppm), and U(VI) release to AGWs occurred primarily due to desorption of U(VI). When reacted in batch experiments with AGWs with compositions representative of the range of chemical conditions in the underlying&nbsp;aquifer, all samples released U(VI) at concentrations greater than regulatory limits within few hours. A semi-mechanistic surface&nbsp;complexation&nbsp;model was developed to describe U(VI)&nbsp;adsorption&nbsp;on sediments collected from near the water table, as a function of pH,&nbsp;alkalinity, and Ca and U(VI) concentrations, using ranges in these variables relevant to groundwater conditions in the aquifer. Dilute (bi)carbonate solution extractions and uranium isotopic exchange methods were capable of estimating adsorbed U(VI) in samples where U(VI) release was predominantly due to U(VI) desorption; these techniques were not effective at estimating adsorbed U(VI) where U(VI) release was affected by dissolution of U(VI) minerals. The combination of extraction and isotopic exchange results, spectroscopic studies, and surface complexation modeling allow an adequate understanding for the development of a geochemical conceptual model for U(VI) release to the aquifer. The overall approach has generic value for evaluating the potential for release of metals and&nbsp;radionuclides&nbsp;from sediments that contain both precipitated and adsorbed contaminant speciation.</span></p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Developments in earth and environmental sciences","largerWorkSubtype":{"id":15,"text":"Monograph"},"language":"English","publisher":"Elsevier","doi":"10.1016/S1571-9197(07)07014-0","usgsCitation":"Bond, D.L., Davis, J., and Zachara, J.M., 2007, Uranium(VI) release from contaminated vadose zone sediments: Estimation of potential contributions from dissolution and desorption, chap. 14 <i>of</i> Developments in earth and environmental sciences, v. 7, p. 375-416, https://doi.org/10.1016/S1571-9197(07)07014-0.","productDescription":"42 p.","startPage":"375","endPage":"416","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":357046,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"7","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5b98c09ce4b0702d0e845c2f","contributors":{"authors":[{"text":"Bond, Deborah L.","contributorId":207537,"corporation":false,"usgs":false,"family":"Bond","given":"Deborah","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":744114,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Davis, James A.","contributorId":69289,"corporation":false,"usgs":true,"family":"Davis","given":"James A.","affiliations":[],"preferred":false,"id":744115,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Zachara, John M.","contributorId":7421,"corporation":false,"usgs":true,"family":"Zachara","given":"John","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":744116,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The processes associated with the Yellowstone hotspot are volcanism, faulting, and uplift and are observed in the geology at the surface. We attribute the driving forces responsible for the northeastward progression of these processes to a thermal plume rising through the Earth&rsquo;s mantle into the base of the southwest-moving North American plate. This progression began 16 million years ago (Ma) near the Nevada-Oregon border and arrived at Yellowstone about 2 Ma. Before arrival of the hotspot, an older landscape existed, particularly mountains created during the Laramide orogeny about 70&ndash;50 Ma and volcanic terrain formed by Absaroka andesitic volcanism mostly between 50&ndash;45 Ma. These landscapes were more muted than the present, hotspot-modified landscape because the Laramide-age mountains had worn down and an erosion surface of low relief had developed on the Absaroka volcanic terrain.</p>\n<p>The Yellowstone Plateau was built by hotspot volcanism of rhyolitic lavas and caldera-forming rhyolite tuffs (ignimbrites). Streams eroding back into the edges of this plateau have created scenic waterfalls and canyons such as the Grand Canyon of the Yellowstone and Lewis Canyon. Rhyolite is poor in plant nutrients and forms sandy, well-drained soils that support the monotonous, fire-adapted lodgepole pine forests of the Yellowstone Plateau. Non-rhyolitic rocks surround this plateau and sustain more varied vegetation, including spruce, fir, and whitebark pine forests broken by grassy meadows. Heat from the hotspot rises upward and drives Yellowstone&rsquo;s famed geysers, hot springs, and mudpots. These thermal waters are home to specialized, primitive ecosystems, rich in algae and bacteria. The rock alteration associated with hydrothermal systems creates the bright colors of Yellowstone&rsquo;s Grand Canyon.</p>\n<p>Basin-and-range-style faulting has accompanied migration of the hotspot to Yellowstone and formed the linear mountains and valleys that occur north and south of the hotspot track, which is the present-day eastern Snake River Plain. High rates of basin-and-range faulting occurred adjacent to the migrating Yellowstone hotspot, creating distinctive landscapes within the GYE such as the Teton Range/Jackson Hole, with characteristic rugged, forested ranges and adjacent flat-floored grassy valleys. The difference in altitude between the mountains and valleys provides a topographic gradient in which vegetation maturation advances with altitude; animal-migration patterns also follow this trend. The valleys provide natural meadows, agricultural land, town sites, and corridors for roads.</p>\n<p>Uplift of the GYE by as much as 1 km (3,000 ft) during the last 5 million years has resulted in ongoing erosion of deep, steep-walled valleys. Many prominent ecological characteristics of Yellowstone derive from this hotspot-induced uplift, including the moderate- to high- altitude terrain and associated cool temperatures and deep snowfall.</p>\n<p>Modern and Pleistocene climate and associated vegetation patterns strongly relate to the topography created by the hotspot and its track along the eastern Snake River Plain. Winter air masses from the moist northern Pacific Ocean traverse the topographic low of the Snake River Plain to where orographic rise onto the Yellowstone Plateau and adjacent mountains produces deep snow. A winter precipitation shadow forms on the lee (eastern) sides of the GYE. During Pleistocene glacial times, this moisture conduit provided by the hotspot-track-produced ice-age glaciers that covered the core of the present GYE. These glaciers sculpted bedrock and produced glacial moraines that are both forested and unforested, sand and gravel of ice-marginal streams and outwash gravels that are commonly covered with sagebrush-grassland, and silty lake sediments that are commonly covered by lush grassland such as Hayden Valley.</p>\n<p>The effects of the Yellowstone hotspot also profoundly shaped the human history in the GYE. Uplift associated with the hotspot elevates the GYE to form the Continental Divide, and streams drain radially outward like spokes from a hub. Inhabitants of the GYE 12,000&ndash;10,000 years ago, as well as more recent inhabitants, followed the seasonal green-up of plants and migrating animals up into the mountain areas. During European immigration, people settled around Yellowstone in the lower parts of the drainages and established roads, irrigation systems, and cultural associations. The core Yellowstone highland is too harsh for agriculture and inhospitable to people in the winter. Beyond this core, urban and rural communities exist in valleys and are separated by upland areas. The partitioning inhibits any physical connection of communities, which in turn complicates pursuit of common interests across the whole GYE. Settlements thus geographically isolated evolved as diverse, independent communities</p>","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"Integrated geoscience studies in the Greater Yellowstone Area— Volcanic, tectonic, and hydrothermal processes in the Yellowstone geoecosystem (Professional Paper 1717)","largerWorkSubtype":{"id":5,"text":"USGS Numbered Series"},"language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/pp1717A","usgsCitation":"Pierce, K.L., Despain, D.G., Morgan, L.A., and Good, J.M., 2007, The Yellowstone hotspot, Greater Yellowstone ecosystem, and human geography: U.S. Geological Survey Professional Paper 1717, 39 p., https://doi.org/10.3133/pp1717A.","productDescription":"39 p.","numberOfPages":"39","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[],"links":[{"id":311432,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":416466,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_82965.htm","linkFileType":{"id":5,"text":"html"}},{"id":311431,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/pp/1717/","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Idaho, Montana, Utah, Wyoming","otherGeospatial":"Grand Teton National Park, Yellowstone National Park","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -114.54345703125,\n              41.02135510866602\n            ],\n            [\n              -114.54345703125,\n              46.619261036171515\n            ],\n            [\n              -107.99560546875,\n              46.619261036171515\n            ],\n            [\n              -107.99560546875,\n              41.02135510866602\n            ],\n            [\n              -114.54345703125,\n              41.02135510866602\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"564c5deae4b0ebfbef0d3499","contributors":{"editors":[{"text":"Morgan Morzel, Lisa Ann lmorgan@usgs.gov","contributorId":761,"corporation":false,"usgs":true,"family":"Morgan Morzel","given":"Lisa Ann","email":"lmorgan@usgs.gov","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true},{"id":171,"text":"Central Mineral and Environmental Resources Science Center","active":true,"usgs":true}],"preferred":false,"id":580058,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Pierce, Kenneth L. kpierce@usgs.gov","contributorId":1609,"corporation":false,"usgs":true,"family":"Pierce","given":"Kenneth","email":"kpierce@usgs.gov","middleInitial":"L.","affiliations":[{"id":481,"text":"Northern Rocky Mountain Science Center","active":true,"usgs":true},{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true},{"id":547,"text":"Rocky Mountain Geographic Science Center","active":true,"usgs":true}],"preferred":true,"id":580054,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Despain, Don G.","contributorId":31147,"corporation":false,"usgs":true,"family":"Despain","given":"Don","email":"","middleInitial":"G.","affiliations":[{"id":481,"text":"Northern Rocky Mountain Science Center","active":true,"usgs":true}],"preferred":false,"id":580055,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Morgan, Lisa A.","contributorId":66300,"corporation":false,"usgs":true,"family":"Morgan","given":"Lisa","email":"","middleInitial":"A.","affiliations":[{"id":481,"text":"Northern Rocky Mountain Science Center","active":true,"usgs":true}],"preferred":false,"id":580056,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Good, John M.","contributorId":69886,"corporation":false,"usgs":true,"family":"Good","given":"John","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":580057,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

In order to protect coastal populations and resources, a detailed understanding of the physical setting and of the processes responsible for change is required. A sustained program of mapping coastal areas provides a means to establish baseline conditions, document change, and, in conjunction with models of physical processes, predict future behavior. Recent advances in mapping technology, including airborne lidars and hyperspectral imagers, allow for the rapid collection of high-resolution elevation data and land use information on a national scale. These rich data sets are critical to evaluating risk associated with coastal hazards, such as flooding during extreme storms. For example, coastal elevation data is a fundamental parameter in storm surge models that predict where flooding will occur, and land use maps serve as the foundation of assessments that identify the resources and populations that are most vulnerable. A comprehensive, national coastal mapping plan that is designed to collect, manage, and distribute these data, as well as to take advantage of recent progress in mapping technology, will provide a wealth of information for studying the processes of physical change, for determining areas vulnerable to coastal hazards, and for protecting and managing our coastal communities and

Therefore, environmental managers in the SCB decided to expand their monitoring program and, starting in 1994, decided to conduct periodic regional assessments of ecosystem condition and assess the overall health of the SCB. Sixty-five different organizations collaborated in 2003 to create the third SCB Regional Monitoring Program (Bight '03). Bight '03 was designed to be integrated regional monitoring program that encompasses regulatory, academic, and non-governmental agencies.</p>\n<br>\n<p>Bight '03 had three components: Coastal Ecology, Shoreline Microbiology, and Water Quality. This report addresses the purpose, approach, findings, and recommendations from the Water Quality component, which focused on contamination-laden stormwater runoff, in particularly its variability in time and space as well as its short-term ecological impacts.</p>\n<br>\n<p>Specifically, the Bight '03 Water Quality component had three primary goals, the first of which was to described the temporal evolution of stormwater plumes produced by the major southern California rivers. Specifically, the study was intended to determine how far offshore the plumes extended, how rapidly they advected, how long before the plumes dispersed and how these properties differed among storms and river systems.</p>\n<br>\n<p>The second goal was to describe how the physical properties (e.g., turbidity, temperature, salinity) of the plume related to biogeochemical and ecological properties that are of more direct concern to the water quality management community. Accomplished primarily through ship-based sampling of water quality parameters, this second goal was to describe how far offshore, and for how ;long after the storm, elevated bacterial concentrations, toxicity, and nutrients could be detected. Similar to the fist goal, the study also addressed how these answers differed among storms and river systems.</p>\n<br>\n<p>The final goal was to determine whether relationships between environmental indicators derived from coincident satellite remote sensing and <i>in situ</i> data sets are sufficiently robust for remote sensing to become a routine water quality monitoring programs. Remote sensing data potentially provide coastal managers with synoptic near-real time regional information about prevailing ocean conditions and hazards that would complement existing field-based sampling protocols, but only if there is a thorough understanding of how to interpret and utilize the proxy measures, such as ocean color. The understanding of these priorities through Bight '03 sampling is intended to provide the basis for developing more efficient, widespread and coast-effective coastal ocean monitoring techniques.</p>\n<br>\n<p>Water quality data were collected across eight major river systems within four geographic regions of southern California. Field measurements included the primary contaminants of interest, i.e., bacterial concentrations, water toxicity, and nutrients, as well as related parameters such as temperatures, salinity, total suspended solids, transmissivity, chlorophyll, and colored dissolved organic material (CDOM) concentrations. For each of the four major regions, i.e., Santa Clara/Ventura Rivers, Ballona Creek/Santa Monica Bay, San Pedro Shelf, and the San Diego, Tijuana Rivers, two stormwater events were sampled for up to three days by ship resulting in 574 water column CTD+ profiles and 705 discrete water samples during 36 ship-days. These data were analyzed in combination with MODIS ocean color satellite remote sensing, buoy meteorological observations, drifters, and HF radar current measurements to evaluate the dispersal patterns, dynamics, and impacts of the freshwater runoff plumes.</p>\n<br>\n<p>Based on these data and resulting analyses, the principal conclusions were as follow:</p>\n<br>\n<p>- Stormwater runoff turbidity plumes were found to be spatially extensive, covering up to 2500 km<sup>2</sup> within the Southern California Bight nearshore zone, and persisting over the entire duration of the post-storm sampling period (at least 3 days).</p>\n<br>\n<p>- The spatial and temporal extent of the portion of the plume with contaminants was far less than that of the turbidity plume, typically representing <10% of its area (30-70% off Tijuana); however, with contaminant impacts generally greatly reduced or absent by the third or fourth day of sampling</p>\n<br>\n<p>- <i>Pseudo-nitzschia</i>, a harmful algae that produces domoic acid, was found to be more abundant than previously reported.</p>\n<br>\n<p>- Accurately describing stormwater runoff plumes requires a combination of <i>in situ</i> and remote sensing assessment tools, with satellite data providing valuable synoptic information.</p>\n<br>\n<p>From these conclusions, the following recommendations are provided:</p>\n<br>\n<p>- Future studies designed to describe stormwater plumes should include a combination of ship - and remote sensing-based methods.</p>\n<br>\n<p>- CDOM is a good proxy of the freshwater runoff plume and should be added as a standard measurement parameter on water quality instrument packages.</p>\n<br>\n<p>- Investigations are needed that assess on a local basis the spatial extent of ecological effects of stormwater plumes early in the storm, ideally accompanied by airborne imagery to provide improved temporal & spatial resolution, to fill in knowledge gaps.</p>\n<br>\n<p>The next Bight regional monitoring program should focus on quantifying nutrient loadings and dynamics in association with stormwater runoff and other sources, and characterize their attendant ecosystem impacts such as phytoplankton blooms.</p>","language":"English","publisher":"Southern California Coastal Water Research Project","publisherLocation":"Coasta Mesa, CA","usgsCitation":"Nezlin, N.P., DiGiacomo, P.M., Weisberg, S., Diehl, D.W., Warrick, J., Mengel, M.J., Jones, B.H., Reifel, K.M., Johnson, S.C., Ohlmann, J., Washburn, L., and Terrill, E.J., 2007, Southern California Bight 2003 Regional Monitoring Program: V. water quality: Technical Report 528, xiv, 157 p.","productDescription":"xiv, 157 p.","numberOfPages":"184","costCenters":[{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true}],"links":[{"id":292381,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -120.5,32.75 ], [ -120.5,34.25 ], [ -117.0,34.25 ], [ -117.0,32.75 ], [ -120.5,32.75 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53f25feee4b0333418718959","contributors":{"authors":[{"text":"Nezlin, Nikolay P.","contributorId":84285,"corporation":false,"usgs":true,"family":"Nezlin","given":"Nikolay","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":498489,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"DiGiacomo, Paul M.","contributorId":19097,"corporation":false,"usgs":true,"family":"DiGiacomo","given":"Paul","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":498484,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Weisberg, Stephen B.","contributorId":11110,"corporation":false,"usgs":true,"family":"Weisberg","given":"Stephen B.","affiliations":[],"preferred":false,"id":498483,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Diehl, Dario W.","contributorId":44476,"corporation":false,"usgs":true,"family":"Diehl","given":"Dario","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":498487,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Warrick, Jonathan A. 0000-0002-0205-3814","orcid":"https://orcid.org/0000-0002-0205-3814","contributorId":48255,"corporation":false,"usgs":true,"family":"Warrick","given":"Jonathan A.","affiliations":[],"preferred":false,"id":498488,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Mengel, Michael J.","contributorId":41356,"corporation":false,"usgs":true,"family":"Mengel","given":"Michael","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":498486,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Jones, Burton H.","contributorId":107213,"corporation":false,"usgs":true,"family":"Jones","given":"Burton","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":498494,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Reifel, Kristen M.","contributorId":86276,"corporation":false,"usgs":true,"family":"Reifel","given":"Kristen","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":498491,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Johnson, Scott C.","contributorId":19492,"corporation":false,"usgs":true,"family":"Johnson","given":"Scott","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":498485,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Ohlmann, J.

The true North reference direction ordinarily is used for \nmeasuring and reporting vector data (strike, trend) in Antarctica, as elsewhere.

Consequently, when performing a \nregional tectonic analysis of vector data (strike, trend) for structures such as faults, dike arrays, or geophysical \nlineaments oriented with respect to North at different sites, it is necessary to rotate the data to a common reference \ndirection. A modular arithmetic function, performed as a spreadsheet calculation, offers the means to unify data sets \nfrom sites having different longitude position, by rotation to a common reference direction. The function is \nS<sub>C</sub> ≡ S<sub>M</sub> + ∆L (mod 360), where SC = converted strike; SM = measured strike; ∆L = angle in degrees longitude between \nreference longitude and study site; and 360, the divisor, is the number of degrees in Earth’s circumference.

The comparison between GPS-derived vertical displacementsand GIA is addressed, showing a good degree of agreement and highlighting the future \nuse of geodetic GPS measurements as constraints in GIA models.

Within the province boundary, the Phosphoria \nis thin and only locally rich in organic carbon. Phosphoria oil \nproduced from reservoirs in the province is thought to have \nmigrated from the Wyoming and Idaho thrust belt. \nLocations (wells) selected for burial history \nreconstructions include three in the deepest parts of the \nprovince (Adams OAB-17, Bighorn 1-5, and Coastal Owl \nCreek); three at intermediate depths (Hells Half Acre, Shell \n33X-10, and West Poison Spider); and three at relatively \nshallow locations (Young Ranch, Amoco Unit 100, and \nConoco-Coal Bank). The thermal maturity of source rocks is \ngreatest in the deep northern and central parts of the province \nand decreases to the south and east toward the basin margins. \nThe results of the modeling indicate that, in the deepest areas, \n(1) peak petroleum generation from Cretaceous rocks occurred \nfrom Late Cretaceous through middle Eocene time, and (2) \nonset of oil generation from the Waltman Shale Member \noccurred from late Eocene to early Miocene time. \nBased on modeling results, gas generation from the \ncracking of Phosphoria oil reservoired in the Park City \nFormation reached a peak in the late Paleocene/early Eocene \n(58 to 55 Ma) only in the deepest parts of the province. The \nMowry Shale and Cody Shale (in the eastern half of the basin) \ncontain a mix of Type-II and Type-III kerogens. Oil generation \nfrom predominantly Type-II source rocks of these units in the \ndeepest parts of the province reached peak rates during the \nlatest Cretaceous to early Eocene (65 to 55 Ma). Only in these \nareas of the basin did these units reach peak gas generation \nfrom the cracking of oil, which occurred in the early to middle \nEocene (55 to 42 Ma). \nGas-prone source rocks of the Mowry and Cody Shales \n(predominantly Type-III kerogen), and the Mesaverde, \nMeeteetse, Lance, and Fort Union Formations (Type –III \nkerogen) reached peak gas generation in the latest Cretaceous \nto late Eocene (67 to 38 Ma) in the deepest parts of the \nprovince. Gas generation from the Mesaverde source rocks \nstarted at all of the modeled locations but reached peak \ngeneration at only the deepest locations and at the Hells Half \nAcre location in the middle Paleocene to early Eocene (59 to \n48 Ma). Also at the deepest locations, peak gas generation \noccurred from the late Paleocene to the early Eocene (57 to \n49 Ma) for the Meeteetse Formation, and during the Eocene \nfor the Lance Formation (55 to 48 Ma) and the Fort Union \nFormation (44 to 38 Ma). \nThe Waltman Shale Member of the Fort Union Formation \ncontains Type-II kerogen.

Changes in ionic strength (I) during transport studies may occur inadvertently as a result of using halides as conservative tracers and may lead to density-induced sinking of the tracer cloud. Substantive increases in I as a result of injection of high concentrations of halide tracers can also result in overestimations of microbial attachment. In order to differentiate \"test\" microorganisms from indigenous subsurface populations and/or from other inadvertently introduced populations, microorganisms used in laboratory or in situ transport tests are typically labeled a priori with a stable tag. Other methods of labeling microorganisms for use in in situ and column transport studies have involved the use of stable isotopes ratio mass spectrometry (IRMS).

Climate is a proxy for the factors that determine whether a population will reproduce enough to offset mortality. Previous climate matching models (e.g., Genetic Algorithm for Rule-set Prediction [GARP]) for brown treesnakes (<i>Boiga irregularis</i>) were unsatisfactory, perhaps because the models failed to allow different combinations of climate attributes to influence a species&rsquo; range limits in different parts of the range. Therefore, we explored the climate space described by bivariate parameters of native range temperature and rainfall, allowing up to two months of aestivation in the warmer portions of the range, or four months of hibernation in temperate climes. We found colonization area to be minimally sensitive to assumptions regarding hibernation temperature thresholds. Although brown treesnakes appear to be limited by dry weather in the interior of Australia, aridity rarely limits potential distribution in most of the world. Potential colonization area in North America is limited primarily by cold. Climatically suitable portions of the United States (US) mainland include the Central Valley of California, mesic patches in the Southwest, and the southeastern coastal plain from Texas to Virginia.</p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Managing Vertebrate Invasive Species – Proceedings of a Symposium","largerWorkSubtype":{"id":12,"text":"Conference publication"},"language":"English","publisher":"USDA/APHIS/WS, National Wildlife Research Center","usgsCitation":"Rodda, G.H., Reed, R., and Jarnevich, C.S., 2007, Climate matching as a tool for predicting potential North American spread of Brown Treesnakes, <i>in</i> Managing Vertebrate Invasive Species – Proceedings of a Symposium, p. 138-145.","productDescription":"8 p.","startPage":"138","endPage":"145","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":325406,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":325405,"rank":1,"type":{"id":11,"text":"Document"},"url":"https://www.aphis.usda.gov/wildlife_damage/nwrc/symposia/invasive_symposium/content/Rodda138_145_MVIS.pdf"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"578dfdaee4b0f1bea0e0f81b","contributors":{"editors":[{"text":"Witmer, G.W.","contributorId":35429,"corporation":false,"usgs":true,"family":"Witmer","given":"G.W.","email":"","affiliations":[],"preferred":false,"id":642805,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Pitt, W.

By taking published estimates of gas exchange, sediment accumulation, and carbon transport for a variety of aquatic systems, we have constructed a budget for the role of inland water ecosystems in the global carbon cycle. Our analysis conservatively estimates that inland waters annually receive, from a combination of background and anthropogenically altered sources, on the order of 1.9 Pg C y-1 from the terrestrial landscape, of which about 0.2 is buried in aquatic sediments, at least 0.8 (possibly much more) is returned to the atmosphere as gas exchange while the remaining 0.9 Pg y-1 is delivered to the oceans, roughly equally as inorganic and organic carbon. Thus, roughly twice as much C enters inland aquatic systems from land as is exported from land to the sea. Over prolonged time net carbon fluxes in aquatic systems tend to be greater per unit area than in much of the surrounding land. Although their area is small, these freshwater aquatic systems can affect regional C balances. Further, the inclusion of inland, freshwater ecosystems provides useful insight about the storage, oxidation and transport of terrestrial C, and may warrant a revision of how the modern net C sink on land is described. ?? 2007 Springer Science+Business Media, LLC.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecosystems","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1007/s10021-006-9013-8","issn":"14329840","usgsCitation":"Cole, J.J., Prairie, Y., Caraco, N., McDowell, W.H., Tranvik, L., Striegl, R.G., Duarte, C., Kortelainen, P., Downing, J.A., Middelburg, J.J., and Melack, J., 2007, Plumbing the global carbon cycle: Integrating inland waters into the terrestrial carbon budget: Ecosystems, v. 10, no. 1, p. 171-184, https://doi.org/10.1007/s10021-006-9013-8.","startPage":"171","endPage":"184","numberOfPages":"14","costCenters":[],"links":[{"id":477031,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.177.3527","text":"External Repository"},{"id":240839,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":213234,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10021-006-9013-8"}],"volume":"10","issue":"1","noUsgsAuthors":false,"publicationDate":"2007-02-13","publicationStatus":"PW","scienceBaseUri":"505a7c91e4b0c8380cd79a62","contributors":{"authors":[{"text":"Cole, J.

The current species complex is simplified with one remaining coregonine, bloater (Coregonus hoyi), deepwater sculpin (Myoxocephalus thompsoni), slimy sculpin (Cottus cognatus), and two dominant invaders, alewife (Alosa pseudoharengus) and rainbow smelt (Osmerus mordax). To better understand the diet relationships of the major offshore forage fishes now in Lake Michigan, diets of bloater, alewife, rainbow smelt, deepwater sculpin, and slimy sculpin were compared. The three sites, chosen to represent northern, central, and southern components of the lake, were sampled during spring, summer, and fall in 1994, and spring and fall in 1995. Forage fishes had diverse and variable diets, with niches differentiated by prey type or location. Diporeia hoyi, Mysis relicta, and zooplankton were the major diet items. The index of relative importance showed benthic (slimy and deepwater sculpins) and pelagic (alewife, rainbow smelt) feeding strategies with opportunistic bloaters incorporating both feeding strategies. Highest diet overlaps were between species of sculpin, and between large and small bloaters; both groups partitioned food by size. Though competition for food may be minimized by spatial segregation of potential competitors, the forage fish in Lake Michigan apparently partition food resources. Fishery management models incorporating food habits of pelagic forage fish would need to take into account diet variation associated with location and season. ?? 2007 E.

We vary these parameters in numerical experiments of an idealized two-dimensional (x-z) estuary to demonstrate their affects on the development and retention of particles in an ETM. Parameters varied are the settling velocity (0.01, 0.1, and 0.5 mm/s), tidal amplitude (0.4 m 12 hour tide and 0.3 to 0.6 m 14 day spring neap cycle), and sediment availability (spatial supply limited or unlimited; and temporal supply as a riverine pulse during spring vs. neap tide). Results identify that particles with a low settling velocity are advected out of the estuary and particles with a high settling velocity provide little material transport to an ETM. Particles with an intermediate settling velocity develop an ETM with the greatest amount of material retained. For an unlimited supply of sediment the ETM and limit of salt intrusion co-vary during the spring neap cycle. The ETM migrates landward of the salt intrusion during spring tides and seaward during neap tides. For limited sediment supply the ETM does not respond as an erodible pool of sediment that advects landward and seaward with the salt front. The ETM is maintained seaward of the salt intrusion and controlled by the locus of sediment convergence in the bed. For temporal variability of sediment supplied from a riverine pulse, the ETM traps more sediment if the pulse encounters the salt intrusion at neap tides than during spring tides. ?? 2007 Elsevier B.V.
