LDEO Deep-Sea Sample Repository CORESEARCH

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.

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).
