At Sea with the Marcus G. Langseth

October 15, 2015


The Research Vessel Marcus G. Langseth, operated by Columbia’s Lamont-Doherty Earth Observatory, sails the world exploring oceans and probing the sea floor and the layers deep beneath it. A new video produced by Columbia University takes a tour of the Langseth and talks to the scientists who work on its decks collecting data about sediments, subduction zones and other geologic features. The Langseth's seismic capabilities help researchers generate 2D and 3D maps of the Earth below the seafloor and better understand the dynamics of tectonic plates, our climate and other Earth systems.

Learn more about the Langseth and its recent expeditions:

  • Scientists on the Langseth sailed off the U.S. East Coast last summer to map the seafloor — land long ago reclaimed by sea rise.
  • In 2014, research from an earlier cruise was published showing that the volcanic plumbing at mid-ocean ridges goes far deeper than previously thought.
  • Scientist Jim Gaherty wrote from a 2013 cruise into the remote Pacific Ocean to study tectonic plates.
  • Pratigya Polissar and others reported from a 2012 expedition in the central Pacific Ocean sampling ancient sediments to see how El Niño and climate varied in the past.
  • That same year, Suzanne Carbotte, Geoff Abers and others wrote about a cruise to study the Cascadia subduction zone off the coast of British Columbia, Washington and Oregon.
  • Donna Shillington reported in from the Langseth during a voyage to the Aleutians in 2011.
