The Lamont–Doherty Earth Observatory (LDEO) is a research unit of Columbia University located on a 157-acre (64 ha) campus in Palisades, N.Y., 18 miles (29 km) north of Manhattan on the Hudson River.
The Lamont–Doherty Earth Observatory (LDEO) was established in 1949 as the Lamont Geological Observatory on the weekend estate of Thomas W. and Florence Haskell Corliss Lamont, which was donated to the university for that purpose. The Observatory’s founder and first director was Maurice "Doc" Ewing, a seismologist who is credited with advancing efforts to study the solid Earth, particularly in areas related to using sound waves to image rock and sediments beneath the ocean floor. He was also the first to collect sediment core samples from the bottom of the ocean, a common practice today that helps scientists study changes in the planet's climate and the ocean's thermohaline circulation.
In 1969, the Observatory was renamed Lamont–Doherty in honor of a major gift from the Henry L. and Grace Doherty Charitable Foundation; in 1993, it was renamed the Lamont–Doherty Earth Observatory in recognition of its expertise in the broad range of Earth sciences. Lamont–Doherty Earth Observatory is Columbia University's Earth science research center and is a core component of the Earth Institute, a collection of academic and research units within the university that together address complex environmental issues facing the planet and its inhabitants, with particular focus on advancing scientific research to support sustainable development and the needs of the world's poor.
To support its research and the work of the broader scientific community, Lamont–Doherty operates the 235-foot (72 m) research vessel, the R/V Marcus Langseth, which is equipped to undertake a wide range of geological, seismological, oceanographic and biological studies. Lamont–Doherty also houses the world's largest collection of deep-sea and ocean-sediment cores as well as many specialized research laboratories.
The Lamont–Doherty Earth Observatory at Columbia University is one of the world’s leading research centers developing fundamental knowledge about the origin, evolution and future of the natural world. More than 300 research scientists and students study the planet from its deepest interior to the outer reaches of its atmosphere, on every continent and in every ocean. From global climate change to earthquakes, volcanoes, nonrenewable resources, environmental hazards and beyond, Observatory scientists provide a rational basis for the difficult choices facing humankind in the planet’s stewardship.
