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.
