Earth Institute research expeditions investigating the dynamics of the planet on all levels take place on every continent and every ocean. Below: selected projects in rough chronological order, and resources to learn more about them. Work in and around New York City is listed separately at bottom. Unless otherwise stated, projects originate with our main research center, Lamont-Doherty Earth Observatory, and are often run in collaboration with other institutions. For expedition blogs written from the field, see our Features archive.
