Lamont-Doherty Earth Observatory seeks fundamental knowledge about the origin, evolution, and future of the natural world.
Decades of Discovery
Since our founding in 1949, Lamont-Doherty Earth Observatory has been a leader in the Earth sciences, with many scientific firsts. We study the planet from its deepest interior to the outer reaches of its atmosphere, on every continent and in every ocean, providing a rational basis for the difficult choices facing humanity.
