R/V Marcus Langseth is a research vessel owned 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 Marcus G. Langseth was dedicated on December 4, 2007, came into service in early 2008, replacing the R/V Maurice Ewing.[3] 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 Western Legend.
The Marcus Langseth was named for Marcus G. Langseth, a Lamont scientist.
In March 2009 Chinese authorities denied the vessel permission to pass between Taiwan and China.[4]
In August 2009, Marcus Langseth was named in a Canadian lawsuit seeking to halt its seismic tomography experiment.[5] The lawsuit was dismissed, diplomatic clearance was issued and the ship sailed after a delay of a day.[6][7]
