The NSF-funded Rolling Deck to Repository (R2R) program envisions the academic fleet as an integrated global observing system, with routine underway data and documentation flowing directly from res
Access to marine seismic reflection images, navigation, acquisition parameters and field data.
LODOS: Laboratory for Ocean Drilling, Observation, and Sampling. The purpose of LODOS is to expand and facilitate drilling-related science and education at Lamont.
The Lamont-Doherty Core Repository is both an archive of sediment (some terrestrial), rocks and coral from beneath the ocean floor, and an archive of the digital data pertaining to the material. They are used for research in climate, environment, many other studies, and for education.

A generous donation of marine seismic technology equipment from CGG Inc. is enabling Lamont to advance its world-class ocean research capacities and opens the door to new areas of sub-seafloor exploration, including an expanded understanding of the undersea dynamics of earthquakes and tsunamis as well as climate science and impacts of sea level change.
Rarely a day goes by without earthquakes shaking the Alaska Peninsula, a string of volcanoes curving off the Alaska mainland into the Pacific. Just off shore, two tectonic plates are converging: The Pacific plate is bending under the North American plate and pushing deep into the Earth. Along this subduction zone, scientists have noticed something unusual. Two adjacent sections that appear almost identical in large-scale characteristics—temperature, angle of subduction, age of the rocks—are exhibiting very different earthquake behaviors over short spans of just tens of kilometers. One section is highly active with small earthquakes; the other is more quiet but has large earthquakes every 50 to 75 years. To get a closer look, Lamont-Doherty Earth Observatory’s research ship, the R/V Marcus G. Langseth, ran seismic surveys to map the ocean floor and the earth beneath it.
The Research Vessel Marcus G. Langseth, operated by Columbia’s Lamont-Doherty Earth Observatory, sails the world exploring oceans and probing the sea floor and the layers deep beneath it. A new video produced by Columbia University takes a tour of the Langseth and talks to the scientists who work on its decks collecting data.
The New Jersey shoreline that sea birds wandered during the last ice age is about 90 miles east of today’s beaches, tens of meters beneath the sea floor. As the ice melted, sea level gradually rose and flooded the coastal terrain, and sedimentation carried out its relentless burial of things past.
This summer, a group of scientists spent several weeks aboard the R/V Marcus G. Langseth looking into that past. Using sound waves, they collected data that will be used to build 3D images of the sediment beneath the ocean floor. They hope to be able to peel back layers of the 3D images to see how coastal landscapes responded to rising sea levels and hurricanes through history.
Starting today, armchair explorers will be able to view parts of the deep ocean floors in far greater detail than ever before, thanks to a new synthesis of seafloor topography released through Google Earth. Developed by oceanographers at Columbia University’s Lamont-Doherty Earth Observatory from scientific data collected on research cruises, the new feature tightens resolution in covered areas from the former 1-kilometer grids to just 100 meters.
Scientists using underwater sensors to explore Lake Rotomahana in New Zealand have uncovered remnants of the Pink Terraces,” once considered the eighth natural wonder of the world.
John Diebold, a marine scientist who sailed the world’s oceans for more than four decades using sound waves to study earthquake faults, underwater volcanoes and other normally hidden features of the seabed, died on July 1 at his home in Nyack, N.Y. The apparent cause was a heart attack, his family said; he was 66.
November 12, 2007 -The academic community’s flagship seismic-research vessel, to be operated by Lamont-Doherty Earth Observatory, was dedicated in Galveston, Tex., Nov 12. The R/V Marcus G. Langseth, funded by the U.S. National Science Foundation for use by universities, research institutes and government agencies across the nation, will generate CAT-scan-like 3D images of magma chambers, faults and other structures miles below the world’s seabeds.
Marine seismic research will play an invaluable role in providing the same level of warning currently in the Pacific Ocean to the Indian and Atlantic Oceans, including the Caribbean Sea and Gulf of Mexico. In January 2005 the Bush Administration committed $37.5 million to expand the current global tsunami detection and warning systems.
The Maurice Ewing, owned by the National Science Foundation and operated by the Lamont-Doherty Earth Observatory (L-DEO), is the only research vessel devoted to obtaining images of the deep earth for fundamental earth science research.
