The Lamont-Doherty Core Repository (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. The collection contains approximately 72,000 meters of core composed of 9,700 piston cores; 7,000 trigger weight cores; and 2,000 other cores such as box, kasten, and large diameter gravity cores. We also hold 4,000 dredge and grab samples, including a large collection of manganese nodules, many of which were recovered by submersibles. Over 100,000 residues are stored and are available for sampling where core material is expended.
Teachers can request sediment samples for educational use. We will send you sediment that is lacking in good stratigraphy (so it is difficult to use in paleoceanographic research) to pick through and explore. This blog will provide background information about the sediment samples you may be sent. We welcome pictures, updates, and are always excited about the cool things you find in your samples!
