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.</span><br

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). </span><br style="color:

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

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.</span><br
