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.

Biology and Paleo Environment

Biology and Paleo Environment is a diverse group of oceanographers, geologists, geochemists, biologists, and environmental scientists who use biology to uncover clues about Earth’s past and study how the modern environment affects biology through its oceans, atmosphere, and land.

Marine Geology & Geophysics

Marine Geology & Geophysics scientists are explorers at heart, motivated by curiosity to understand some of the most remote and forbidding parts of our planet, from the active margins beneath the oceans to the polar ice sheets.

Marine/Large Programs

From expeditions aboard the R/V Marcus G. Langseth to seafloor mapping to ship-based experiences for students and more, Marine/Large Programs marine geoscientists and experts are seafaring explorers of Earth's history and environment.

Ocean & Climate Physics

Researchers in Ocean & Climate Physics study Earth's climate dynamics from sea ice to the oceans to the atmosphere in order to document change, build an understanding of controlling forces, and develop cutting-edge computer models for crucial predictions.

Seismology, Geology & Tectonophysics

Seismology, Geology & Tectonophysic scientists are at the forefront of seismology, solid earth dynamics, rock mechanics, and sedimentary geology, making important contributions to the study of earthquakes, Earth’s structure, and  motions and deformation of tectonic plates.

Research News

New research from Columbia climate scientists shows that the 1987 ozone treaty, designed to protect the ozone layer, has postponed the occurrence of the first ice-free Arctic by as much as 15 years.

On July 1, Jeffrey Shaman will become interim dean of the Climate School, continuing the work of co-deans Alex Halliday, Jason Bordoff, Ruth DeFries, and Maureen Raymo, climate leaders who built the School’s strong foundation.

Inspired by Bash the Trash, kids had a chance to make musical instruments out of reusable materials, then perform in a parade.

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.
