| Marcus G. Langseth |
Rain or shine, research goes on. The Marcus G. Langseth is loaded and ready for more research projects as she passes through Shoreline.
From Maritime Hawaii
She is a research vessel owned by the National Science Foundation (NSF) and operated by Columbia University’s Lamont-Doherty Earth Observatory. As a seismic research facility, the ship is able to provide 2D and 3D images of the Earth’s structure beneath the sea. She is also capable of supporting other marine geology/geophysics-related work. She was named after Dr. Marcus Gerhardt Langseth, who was a scientist at the Lamont-Doherty Earth Observatory. 6 May 2017.

From Lamont-Doherty Earth Observatory
Langseth is classed by the American Bureau of Shipping as A-1 Baltic Ice Class IA and Coast Guard inspected; certificated to carry a total of 55 personnel of which approximately 20 are the ship's crew.
Originally constructed as a seismic vessel the Langseth was acquired in 2004, modified, and outfitted to perform the tasks required of a general purpose research vessel. This includes hull mounted 3.5 and 12 khz transducers and a Simrad 1x1 degree deep ocean multibeam swath bottom mapping system.
Particularly unique to the academic research vessel are the Marcus Langseth's extensive geophysical capabilities which include a Syntrak 960-24 seismic recording system with four 6km solid-state hydrophone streamer cable and a 2000 psi, 40 pneumatic sound source array towed in four " strings" that can be configured either as a single, 2D source or dual, alternating 3D source arrays.
