The Lamont-Doherty Core Repository holds one of the world’s most unique and important collections of scientific samples from the deep sea—approximately 72,000 meters of sediment cores from every major ocean and sea. It is both an archive of sediment (some terrestrial), rocks and coral from beneath the ocean floor, and an archive of the digital data pertaining to the material. Collecting a core a day, Lamont scientists catalogue materials as much as 100 million years old. The cores, largely collected by Lamont’s own research vessels, are a central resource for the global scientific community, which uses them for studies of Earth’s past and current environment, especially in regard to climate change. more: news.columbia.edu/sediment#
