NGDC's Marine Geology and Geophysics global marine sediment and hardrock databases aim at serving as the international focal point for marine geology data management. All data are in the international public domain, available globally to any interested individual or group. We have pictures of the Earth, planets, stars, and other cool stuff, as well as the stories behind those images. Hosted by the Scripps Institution of Oceanography Library, this site provides a comprehensive directory of Oceanography Institutions on the Web. Federal, State and private institutions are listed.
Institutional resources vary.
This Website explains the history of our new understanding of the Earth and provides a brief overview of the theories behind it. Includes Plate Tectonics animations, quicktime movies and AVI files to show how the continents have changed position over time. Directories for the agency's personnel and products are available here, and descriptions of USGS activities and mapping methods. Earth Science issues documents which provide synopses of geoscience issues. An on-line catalog provides access to the Museum's enormous collections, which are ranked 4th in America in size.
