Archive of Geosample Data and Information from the University of Southern California (USC) Department of Earth Sciences

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: May 06, 2026 at 09:32 AM | Dataset Last Updated: December 31, 1977 at 12:00 AM
Metadata describing geological samples curated by Earth Sciences Department of the University of Southern California (USC) collected during the period from 1922 to 1981 were coded and contributed by USC to the Index to Marine and Lacustrine Geological Samples (IMLGS) database. Descriptions are for 7,472 cores, grabs, and dredges, most collected in the eastern Pacific Ocean, offshore California, during 390 cruises of the Velero IV, 1 cruise of the Thomas G. Thompson, and 1 cruise of the Agassiz. Please contact the USC Department of Earth Sciences for the current status of the USC collection.
