Deep-Sea Core Sample Repository and Database at Lamont-Doherty Earth Observatory and LDEO/IRI Climate Data Library

The Core Repository contains approximately 72,000 meters of core composed of 9,700 piston cores; 7,000 trigger weight cores; and 1,500 other cores such as box, kasten, and large diameter gravity cores. There are also 4,000 dredge and grab samples including a large collection of manganese nodules, and many samples recovered by submersibles.

The core sample can be searched through the Deep-Sea Core Database at the LDEO/IRI Climate Data Library for coordinates of the site, water depth, topography, core length or dredge size, sample device, date and time of retrieval. "ingrid.ldgo.columbia.edu/SOURCES/.LDEO/.Deep_Sea_Core.cuf/" Data on the cores is stored at NOAA/National Gephysical Data Center (NGDC) Marine Geology and Geophysics (MGG): "ngdc.noaa.gov:80/mgg/curator/curator.html"
