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.
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.

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.
