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

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.

NOAA National Centers for Environmental Information. doi:10.7289/V5M61H7G [date of access].", "Please consult the Curator before proposing to do research on any sample discovered through the IMLGS or the NCEI archive. LDEO has long had an open-policy toward sample requests from academic researchers world-wide. LDEO requests that material provided not be used for work other than the stated purpose (unless follow-up permission is granted), and that sub-samples of the material not be sent to other investigators (again, unless permission is granted). LDEO also requests that you send an electronic copy of all publications resulting from the use of the requested material. This helps document the importance of the repository to the scientific community and justify the funding LDEO receives.", "Sample metadata and most data/images are available online for free download. Additional, full-resolution images from the offline archive may be available. Contact NCEI for more information.", "While every effort has been made to ensure that these data are accurate and reliable within the limits of the current state of the art, NOAA cannot assume liability for any damages caused by any errors or omissions in the data, nor as a result of the failure of the data to function on a particular system. NOAA makes no warranty, expressed or implied, nor does the fact of distribution constitute such a warranty."]
