Lamont-Doherty is a unique research enterprise, bringing together courageous, entrepreneurial thinkers dedicated to bold exploration and discoveries that illuminate our understanding of Earth’s processes and the myriad ways our planet is changing as our climate warms.
Since its founding in 1949, Lamont has been a leader in the Earth sciences, and is now the scientific research heart of the Columbia Climate School founded in 2020. We are a dynamic community of 500 scientists, students, and staff, with nearly 300 PhD-level researchers, and 80-90 graduate students involved in research.
Our scientists 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.

Community Research Infrastructure at LDEO
Researchers at Lamont-Doherty Earth Observatory develop, steward, and host a globally significant portfolio of open data systems, physical collections, laboratories, and research platforms that support discovery across the Earth and planetary sciences. These community resources are designed to ensure the long-term preservation, accessibility, and reuse of data and samples, enabling research that spans disciplines, scales, and generations.
Research News
New research shows that gas bubbles played a central role in controlling how fast and far the lava traveled, and that lava flow models need to account for bubbles to more accurately forecast where lava will stop.
Researchers studying a lake drainage event in Greenland determined that large amounts of meltwater can lead to massive glacier calving events and accelerate ice sheet loss.
As a dangerous early-summer heat wave covers swaths of the globe, Columbia Climate School experts discuss the impacts of extreme heat.
Lamont researchers are in the field studying the dynamics of the planet on every continent and every ocean. Journalists may join and cover expeditions when possible. Learn more about this essential fieldwork.
