Aeromagnetic Trackline Data System

There is a tremendous amount of geophysical trackline data, airborne and marine, available for on-line searching through NGDC's GEOphysical DAta System GEODAS). Search the aeromagnetic inventory below, or see what other data are available through GEODAS. Please see the "note" below concerning access to the U.S. airborne data now being served by the US Geological Survey.

NOTE: The USGS has taken over the archive and distribution of the US airborne data. They have been working for several years to process, document, and post data on-line free of charge. Please contact the USGS Pat Hill (pathill@usgs.gov 303 236-1343) for access to the desired surveys or visit the following USGS websites:
