R/V Marcus Langseth is research vessel owned by the National Science Foundation and operated by the Lamont-Doherty Earth Observatory (LDEO) of Columbia University as a part of the University-National Oceanographic Laboratory System (UNOLS) fleet.[1][2] The "Langseth" came into service in early 2008, and has replaced the R/V Maurice Ewing. Langseth is intended primarily to collect multichannel seismic data, including 3-D surveys. The ship was purchased from the geophysical survey company WesternGeco in 2004, having previously been named M/V Western Legend.

The Marcus Langseth was named for Marcus G. Langseth, a Lamont scientist.

In August 2009, Marcus Langseth has been named in a Canadian lawsuit seeking to halt its seismic tomography experiment [1]. The lawsuit was dismissed, diplomatic clearance was issued and the ship sailed after a delay of a day.[3]
