Rocks and deposits
Solid masses that make up the earth's crust as well as accumulations of materials. Use for major rock types and unconsolidated deposits. For deposits of economic value, see related terms.
Remaining recoverable petroleum in giant oil fields of the Los Angeles Basin, southern California [ More info] We estimated between 3.2 and 5.6 billion barrels of additional oil may be recovered with existing technology in this area using a probabilistic geology-based assessment methodology.
Review of flow rate estimates of the Deepwater Horizon oil spill [ More info] We assess the degree to which a consensus was reached on the flow rate of the well by comparing in situ observations with a time-dependent flow rate model derived from pressure readings taken after the Macondo well was shut in for the well integrity test.
Science supporting Gulf of Mexico oil-spill response, mitigation, and restoration activities-Assessment, monitoring, mapping, and coordination [ More info] Explains and shows data and expertise we were able to provide to Federal agencies and decision makers to help them deal with this difficult situation.
Selected references on fossils and paleontology [ More info] Bibliography of books, periodicals, fossil collecting guides, audiovisual aids, videos, filmstrips, charts, and posters which may be borrowed from libraries or purchased if still available.

Shoreline surveys of oil-impacted marsh in southern Louisiana, July to August 2010 [ More info] Locations of survey points, a photographic record of each site, field observations of vegetation cover and descriptions of oil coverage in the water and on plants, including measurements of the distance of oil penetration from the shoreline.
South Florida Ecosystem History Project [ More info] Project is designed to integrate studies from a number of researchers compiling data from terrestrial, marine, and freshwater ecosystems within south Florida. Links to publications, maps, posters, and data of studies.
Summary of Bed-Sediment Measurements Along the Platte River, Nebraska, 1931-2009 [ More info] Studies of the size of bed sediment along the length of a river through time show how the river channel will be affected by development or management efforts.
The Alaska Geochemical Database: v. 1.0 - Geologic Materials [ More info] Geochemical analyses of rocks, mineral separates, lake and stream sediment bulk samples, heavy-mineral concentrates, and soils collected by USGS in Alaska from 1962 through 2009.
