Archive of Geosample Data and Information from the U.S. Extended Continental Shelf (ECS) Project.

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 27, 2026 | Last Modified: 2015-09-14T00:00:00.000+00:00
Geological samples collected as part of the U.S. Extended Continental Shelf (ECS) Project are curated by the U.S. Geological Survey, a partner in the ECS Project. To date, dredges and cores have been collected from the Arctic Ocean floor, and small sediment samples have also been collected from the Bering Sea. According to ECS policy, application can be made by qualified researchers to the ECS Samples Curator to obtain portions of these samples for study. Related sample data, information, and images generated at sea, during ECS post-cruise working parties, and other research results are available for public access via the ECS Information Management System (ECS IMS) website maintained by NOAA's NCEI. Both ECS samples and related data are searchable through the Index to Marine and Lacustrine Geological Samples (IMLGS) database maintained by NCEI.
