Lamont-Doherty Earth Observatory (LDEO) Curatorial Facility
The Lamont-Doherty Deep-Sea Sample Repository is located in the Core Laboratory at the Lamont-Doherty Earth Observatory in Palisades, New York, approximately 15 miles north of the Columbia University main campus.
Sediment cores and dredges from every major world ocean and sea, rivers and lakes, are archived in the Core Repository. A great number of cores in the archives were collected under the directive of Maurice Ewing, Lamont's founder and first director, who insisted that "a core-a-day" be taken whenever a Lamont vessel was at sea. As our ships criss-crossed across the oceans, he felt that one might never again pass over that particular piece of ocean terrain, and the opportunity to core should be taken for future researchers. Our irreplaceable global collection of legacy material is the result of Ewing's vision of a "library" of cores.
The Lamont Repository is largely supported by the Ocean Science Division of the National Science Foundation, and also by the Coastal Geoscience Program of the Office of Naval Research.
The Core Repository occupies 11,891 sq ft of space consisting of a Curatorial lab, main office and core library, Physical Properties lab, a cutting/sampling room, two walk-in refrigerators, and a dredge storage area. All of the legacy cores taken under Ewing's directive are stored dry at room temperature. Post-1985 cores are refrigerated, stored wet in D-tubes. Dredges are stored in crates in a weather-protected shed.
LDEO has a history of an open-policy toward sample requests for academic research world-wide. Lamont's "Policy and Procedures for Distribution of Samples and Sample Information" is available on request. We ask that two copies of all publications resulting from use of the material be sent to the core repository, or a copy of unpublished data.
In addition to providing a sampling service to anyone not able to visit the repository, we have available several methods of analyzing cores by non-destructive methods. More information is available on the Lamont website.
