Archive of Geosample Data and Information from the Columbia University Lamont-Doherty Earth Observatory (LDEO) Lamont-Doherty Core Repository (LDCR)

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: May 05, 2022 at 12:00 AM
The Lamont-Doherty Core Repository (LDCR), operated by the Lamont-Doherty Earth Observatory (LDEO) of Columbia University, is a partner in the Index to Marine and Lacustrine Geological Samples (IMLGS) database, contributing information to the IMLGS to help researchers discover geological samples curated in their facility. The partner repository also sends related data, documents, and imagery to NCEI for long-term archive, but the originating institution is the definitive source of information related to their sample collection. The LDCR contains one of the world's most unique and important collection of scientific samples from the deep sea. Sediment cores from every major ocean and sea are archived at the Core Repository. Materials available through the NCEI archive (other than core metadata) are core photos and descriptions, both of which were done at the time a core was opened; information/photos of what a core is like now are available upon request. If you would like to request material from LDCR holdings or want to know what other services are offered (grain size, coulometry, MST, etc.), please check the LDCR website for more information.
