Lamont–Doherty Earth Observatory 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 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
