The World Data Center for Geophysics in Boulder, Colorado is hosted by the National Geophysical Data Center (NGDC). NGDC's vision is to be the world's leading provider of geophysical and environmental data, information, and products. NGDC's mission is to provide long-term scientific data stewardship for geophysical data, ensuring quality, integrity, and accessibility. Faced with ever expanding data volumes and types of data, NGDC is developing more innovative techniques for science data stewardship based in part on data mining and fuzzy logic. Use of these techniques will allow NGDC to more effectively provide data stewardship for its own scientific data archives and perhaps the broader World Data System.
