R/V Marcus G. Langseth
Lamont-Doherty Earth Observatory's Office of Marine Operations (OMO) currently operates the research vessel Marcus G. Langseth that serves as the national seismic research facility for the United States academic research community. The R/V Marcus G. Langseth's unique seismic capability allows it to provide both 2D and 3D maps of the earth's structure miles below the seafloor. Utilizing the vessel's other capabilities, expeditions have collected sediment cores for understanding climate variations throughout the Earth’s history, sampled seawater for determining physical and chemical properties of the oceans, and deployed remotely operated vehicles (ROVs) for studying submarine volcanoes. Scientists and researchers from all over the world are encouraged to participate in research programs aboard the Langseth.
