This updated global inventory reports on natural gas hydrate recovered or inferred from geophysical, geochemical, or geological evidence. Includes links to world location maps, inventories, references and posters. Also in PDF format files.
Scientific studies on the polar regions will receive greater attention during 2007-2008 as a result of USGS participation in the International Polar Year, coordinated in the US by the National Research Council, NSF, and NASA.
We need refined regional understanding of climate change, effective oil-spill risk assessment, preparedness, and response, an analysis of cumulative effects (natural and human), better geospatial data for the area, in an integrated approach.
Downloadable data with software showing composite average ocean characteristics (sea-surface temperature and sea-ice concentration). Includes documentation, source code, data, and executable programs for Linux and Microsoft Windows.
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.
New synoptic data from samples collected in the Arctic Ocean and insights into the patterns and extent of ocean acidification. This foundational geochemical information will help us to understand potential risks to Arctic resources.
Polar bears are endangered by reduction in Arctic sea-ice concentration and by reduction in their supply of prey for food. Models shown here indicate anticipated effects on polar bear populations of several climate change scenarios.
We estimated mean undiscovered, conventional, technically recoverable petroleum resources in the Barents Sea Shelf to be more than 76 billion barrels of oil equivalent using a geology-based assessment methodology.
