Assessment of Undiscovered Petroleum Resources of the North and East Margins of the Siberian Craton, Russian Federation [More info]: We estimated the mean undiscovered, conventional petroleum resources at 28 billion barrels of oil equivalent, including approximately 8 billion barrels of crude oil, 106 trillion cubic feet of natural gas, and 3 billion barrels of natural gas liquids.
Assessment of undiscovered, conventional oil and gas resources of Mexico, Guatemala, and Belize, 2012 [More info]: We estimated means of 19 billion barrels of oil and 83 trillion cubic feet of undiscovered natural gas resources in 10 geologic provinces of this area using a geology-based assessment methodology.
Atlantic margin offshore sediments: cooperative database and GIS development website [More info]: This site is designed to provide information on federal interagency and cooperative developments related to coastal sand and gravel resources and management issues along the Atlantic continental margin.
Atlas of Antarctic research [More info]: Entry to the Atlas of Antarctic Research giving a common base map for displaying research results, data, and descriptions of projects. Layers can be viewed or downloaded as Digital Elevation Models (DEMs), digital aerial photos, and satellite images.
Bedform sedimentology [More info]: Bedform sedimentology home page with links to information on sedimentary structures including, explanatory text, computer-generated images and movies, photographs, and bedform simulation software.
Biological resource status and trends: Contaminants in soil [More info]: Information concerning status and trends of biological resources, focusing on contaminants in soil
Circum-Arctic Resource Appraisal: Estimates of Undiscovered Oil and Gas North of the Arctic Circle [More info]: 90 billion barrels of oil, 1,669 trillion cubic feet of natural gas, and 44 billion barrels of natural gas liquids may remain to be found in the Arctic, of which approximately 84 percent is expected to occur in offshore areas.
Coal database for Cook Inlet and North Slope, Alaska [More info]: Published and nonconfidential unpublished coal data from wells in Alaska. Includes well locations, depth and thickness of coal in well, formation type and name, and business administrative information such as permit numbers.
Computer simulation of reservoir depletion and oil flow from the Macondo well following the Deepwater Horizon blowout [More info]: This model estimates, by simulation, the reservoir pressure, flow rate, and volume of oil discharged, and the report discusses the uncertainty in the estimates.
Cross-bedding, bedforms,and paleocurrents [More info]: The on-line version of Cross-Bedding, Bedforms, and Paleocurrents, with computer images, photographic images, and text.
