DataONE - The Data Observation Network for Earth (DataONE) is a distributed framework and sustainable cyberinfrastructure that give open, persistent, robust, and secure access to well-described and easily discovered Earth observational data. Supported by the NSF, DataONE ensures preservation and access to multiscale, multidiscipline, and multinational science data across domain boundaries. DataONE will make biological data available from the genome to the ecosystem; make environmental data available from atmospheric, ecological, hydrological, and oceanographic sources; provide secure and long-term preservation and access; and engage scientists, land-managers, policy makers, students, educators, and the public through logical access and intuitive visualizations.
dbSEABED - marine substrate information from seafloor surveys is unified in this source, which can import into your GIS or relational database.
Discovering Antarctica - An outreach site from the Royal Geographical Society in partnership with the British Antarctic Survey and U.K. Foreign and Commonwealth Office. Multimedia and interactive activities engage visitors in exploring the physical, biological, and human story of the Antarctic continent. Topics are organized in non-traditional but logical ways. Winner of the Geoscience Information Society Best Website Award for 2009.

GB3D Type Fossils Online - funded by Jisc, this database includes type specimens, held in British collections, of macrofossil species and subspecies found in the UK, including photographs, stereo pairs, and 3D digital models.
GeoCommunicator - from the Bureau of Land Management and U.S. Forest Service, well-organized access to land and mineral use records, a map server showing public lands, Public Land Survey System (PLSS) and other survey-based data, and reference documents on cadastral survey and land records.
Geo.Data.gov - the portal for GIS and spatial data from the U.S. government. Includes GIS for the Nation, the National Map, geographic names, and data in tagged categories such as geological and geophysical, atmosphere and climatic, biology and ecology, and environment and conservation.
Geologic Atlas of the United States - TIFF images of 227 USGS map folios, produced between 1894 and 1945, with topographic and geologic maps. The maps cover selected areas of the United States, including Colorado's Engineer Mountain, Needle Mountains, Spanish Peaks, and Colorado Springs. The images take about 10-15 minutes to load but are publication-quality when they do (no low-res PDFs here).
Global Change Master Directory - a clearinghouse of earth science data. Browse by topic (atmosphere, biosphere, climate indicators, cryosphere, human dimensions, hydrosphere, paleoclimate, etc.), data centers, locations, instruments, platforms, or projects.
Global Runoff Data Center - the worldwide repository of discharge data and associated metadata, focusing on global river discharge data for the sake of research linking global and local change issues. Operates under the auspices of the World Meteorological Organization (WMO) with the support of the Federal Institute of Hydrology, Germany.
International Ocean Discovery Program - sponsored by funding agencies in the United States, Europe, and Japan, this program conducts basic research into the history of the ocean basins and the nature of the crust below the seafloor.
International Polar Year - This portal is the official gateway to all things IPY, including participating agencies and organizations, research projects, classroom resources, and galleries.
International Tree-Ring Data Bank - maintained by the NOAA Paleoclimatology Program and World Data Center for Paleoclimatology, this data bank includes raw ring width or wood density measurements and site chronologies for more than 2000 sites on six continents.
