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.
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.
The Arctic is warming faster than other regions of the world due to positive climate feedbacks associated with loss of snow and ice. The USGS has modeled the future responses of polar bear and Pacific walrus populations to this environmental change.
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.
An introduction to three related USGS digital libraries: the general-purpose Marine Realms Information Bank (MRIB); the regionally focused Monterey Bay Science (MBS) Digital Library; and the topically focused Coastal Change Hazards (CCH) Digital Library.
