Presenter: Sean Higgins (Director - Office of Marine Operations, Lamont-Doherty Earth Observatory)
Abstract: The R/V Marcus G. Langseth (Langseth) is operated by Columbia University on behalf of the National Science Foundation (NSF). The Office of Marine Operations (OMO) located at the Lamont-Doherty Earth Observatory (L-DEO) manages the Langseth facility. The Langseth is a global class vessel that provides a unique 3D and 2D multi-channel seismic (MCS) imaging and general purpose oceanographic surveying capabilities to the UNOLS academic fleet and the science community. Purchased in 2004 and refit for both seismic and general oceanographic functions from 2005-2007, the Langseth began its operations at the end of 2007 with a series of shakedown and source calibration cruises.
The Langseth is one of the first academic ships in the world to have 3-D acoustic imaging capability. This ship is unique in that it serves as the U.S. National Marine Seismic Facility in the U.S. academic fleet. Its role in supporting research funded by the NSF and other U.S. Government Agencies along with others highlights the importance of marine seismology for U.S scientific research. The Langseth operations often very closely with OBSIP that manages the Ocean Bottom Seismometer pool that consists of instruments from SIO, WHOI, and L-DEO).
The Langseth began operations in 2008 and has successfully carried out more than 27 marine seismic projects around the globe. This has included work in the Arctic Ocean (Chukchi Sea), Bering Sea, Gulf of Alaska, Aleutians, offshore northwestern U.S., Marianas, Taiwan, Azores, Spain, Northwest and Central Pacific, Costa Rica, N. Atlantic, US East Coast and the Gulf of Mexico. Altogether, our science missions since 2008 encompass almost 1500 operational days. These cruises have science parties made up of scientists and students from the US and around the world.
The Langseth is equipped with flexible lab space and room for multiple lab vans and containers on multiple decks that has also allowed it to take on coring cruise in the Line Islands and support a multi-disciplinary Jason ROV operation in the Pacific NW. The science sonar pod on the hull of the vessel houses a Kongsberg EM122 (1x1 array) MB system, a Knudsen 3.5kHz Chirp SBP, and a Teledyne 75 Hz ADCP. In addition, we deploy towed magnetometers, an onboard gravimeter, and routinely make surface pCO2 measurements with an uncontaminated seawater system.
