Extended Continental Shelf Physical Samples

The U.S. Geological Survey is the designated repository for U.S. Extended Continental Shelf (ECS) physical samples collected for the ECS project and coordinates all outside sample requests.

The priority for geologic samples collected as part of the U.S. Extended Continental Shelf (ECS) Project is their application to delineating the U.S. ECS, however the U.S. ECS Task Force recognizes the important scientific value of these samples and encourages their study and open publication of scientific findings.

Geologic samples are archived at the USGS Woods Hole Coastal and Marine Science Center samples repository. Policy for sample request and analysis, as well as data collection and distribution can be found in the ECS Data, Publications, and Physical Samples Policy and Procedures documentation.
