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. |
