Welcome to Lamont-Doherty Earth Observatory

Lamont-Doherty Earth Observatory (LDEO), located in Palisades, New York, is a community of 500 scientists, students, and staff, with nearly 300 PhD-level researchers, and more than 80 graduate students involved in research. Since 1949, they have sought fundamental knowledge about the origin, evolution, and future of the natural world.

LDEO is also the scientific research heart of Columbia Climate School, which was founded in 2020 to develop and inspire knowledge-based solutions and educate future leaders for just and prosperous societies on a healthy planet. From mapping the seafloor to developing a computer model to predict an El Niño weather event, LDEO has a long history of enhancing our understanding of the Earth.

Areas of Study

Biology and Paleo Environment

Researchers uncover clues about Earth's past environment and strive to understand how the modern environment—through its oceans, atmosphere, and land—affects present-day biology.


Using advanced chemical and isotope analyses, researchers investigate the processes, past and present, that govern Earth's environments, as well as the socioeconomic impact of those processes.

Marine Geology and Geophysics

Scientists in the MG&G Division use cutting-edge technologies to make new and exciting observations of the polar ice sheets and geological processes occurring on and beneath the seafloor.

Ocean and Climate Physics

Climate change is a crucial factor that has influenced human history over the ages. Therefore, reliable prediction is vital both to humankind's future and to the well-being of the planet.

Seismology, Geology, and Tectonophysics

Researchers are making lasting contributions to the study of earthquakes, the structure of the Earth’s crust, mantle, and core, and the large-scale motions and deformation of the tectonic plates.

Meet the Research Vessel Marcus G. Langseth

The Langseth, operated by LDEO for the National Science Foundation, supports worldwide oceanographic research. The vessel allows researchers to collect data about the Earth and oceans, generate 2D and 3D maps of what’s below the seafloor, collect sediment cores, and more. You can track the Langseth around the globe.


Mark Dion's The Field Station of the Melancholy Marine Biologist
Renowned visual artist Mark Dion presents the new installation, The Field Station of the Melancholy Marine Biologist, which opens October 8 on Governors Island. The event will be introduced and followed by a conversation with Maureen Raymo, Director of Lamont-Doherty Earth Observatory, and Co-Founding Dean of Columbia Climate School.
Thursday, October 7, 6:30 pm

Ocean & Climate Seminar Series
Fridays this fall, LDEO will be holding in-person and virtual seminars with experts from around the country on a variety of topics, such as tropical cyclone modeling, greenhouse gases, and the El Niño-Southern Oscillation.
Friday, October 8 – Friday, December 10
