The Lamont-Doherty Earth Observatory Deep-Sea Sample Repository is both an archive of sediment and rocks from beneath the ocean floor, and an archive of the digital data pertaining to the material. They are used for research in climate, environment, many other studies, and for education.

The dots on the map above are sites where deep-sea cores have been taken and archived at the Lamont Deep-Sea Sample Repository. The image links to a map powered by Google where you can select cores available for sampling, and view their Megascopic Descriptions.

You can find out what cores are, how we get cores, see some of the research results from working on cores, and find out more about the Core Repository. You can also search our database for core sites of a given area, for mineralogy, micropaleontology, and many other core attributes linked to core sampling history, or search and plot cores from Research Vessels VEMA and CONRAD. Cores from many other repositories are listed in a database at the National Geophysical Data Center in Boulder, Colorado (NGDC).
