|Airborne Magnetic Trackline and Survey Data (Vector and Scalar Observations)
|The NOAA National Centers for Environmental Information (formerly National Geophysical
Data Center) receive airborne magnetic survey data from US and non-US agencies. In
an effort to provide a central library for digital aeromagnetic data in the public
domain, NCEI is continuing to assimilate new digital data from aeromagnetic surveys
in the United States. Major contributors to this important data base include the U.S.
Geological Survey, U.S. Naval Oceanographic Office, U.S. Naval Research Laboratory,
Woods Hole Oceanographic Institution, the University of Texas, and the Natural Resources
Canada (NRCAN). The details of these surveys are contained in an automated inventory
system Geophysical Data System (GEODAS). The philosophy of exchange of data from the
archive for new contributions has stimulated many organizations to transfer their
data holdings to the Data Center.
