March 2023 - February 2024
Project Type: Facilities & Operations

DESCRIPTION: A proposal is made to fund instrumentation on the R/V Marcus Langseth, a 235? Global seismic vessel with general oceanographic capabilities. The vessel is owned by Columbia University and operated by Lamont-Doherty Earth Observatory of Columbia University under a cooperative agreement with NSF. The Langseth is unique in the Academic Fleet in that it provides a combination of capabilities for imaging the oceans, the seafloor and the solid earth beneath the sea. It is the only vessel in the world dedicated to academic research that can conduct 3D seismic surveys as well as extended offset 2D surveys. The tuned, linear source array, consisting of up to 36 airguns, with a total capacity of 6,600 cu in is also unique asset of this vessel.
