Sec. 950.5  National Geophysical and Solar-Terrestrial Data Center (NGSDC).

    The National Geophysical and Solar-Terrestrial Data Center acquires, 
processes, archives, analyzes, and disseminates solid Earth and marine 
geophysical data as well as ionospheric, solar, and other space 
environment data; develops analytical, climatological, and descriptive 
products to meet user requirements; and provides facilities for World 
Data Center-A (Solid-Earth Geophysics, Solar Terrestrial Physics, and 
Glaciology).
    (a) Geophysical and solar-terrestrial data available from NGSDC 
include:
    (1) Marine geology and geophysics. Bathymetric measurement; seismic 
reflection profiles; gravimetric measurements; geomagnetic total field 
measurements; and geological data, including data on heat flow, cores, 
samples, and sediments.
    (2) Solar-Terrestrial physics. Ionosphere data, including ionograms, 
frequency plots, riometer and field-strength strip charts, and 
tabulations; solar activity data; geomagnetic variation data, including 
magnetograms; auroral data; cosmic ray data; and airglow data.
    (3) Seismology. Seismograms; accelerograms; digitized strong-motion 
accelerograms; earthquake data list (events since January 1900); 
earthquake data service with updates on a monthly basis.
    (4) Geomagnetic main field. Magnetic survey data and secular-change 
data tables.
    (b) Queries should be addressed to: National Geophysical and Solar-
Terrestrial Data Center, National Oceanic and Atmospheric 
Administration, Boulder, CO 80303, tel. 303-499-1000, ext. 6215.
