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

browse graphicimage of sea floor sample locations
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.
