"The National Environmental Satellite, Data, and Information Service (NESDIS) has the role of collecting, managing, and disseminating the great mass of information produced by the scientific observation of interplanetary space and the physical world. Data activities in seismology , gravity, geomagnetism, marine geology and geophysics, geothermics, and solar-terrestrial physics are directed by NESDIS' National Geophysical Data Center (NGDC) in Boulder, Colo. NGDC also operates World Data Centers (WDC-A) f o r Marine Geology and Geophysics, for Solar-Terrestrial Physics, for Solid Earth Geophysics, and for Glaciology under the auspices of the National Academy of Sciences.
