The R/V Marcus G. Langseth ( formerly Western Legend ) has been purchased by the U.S. National Science Foundation (NSF) and Columbia University, as a replacement for the retiring R/V Ewing. Conversion of the vessel is scheduled to be completed, and science operations begun, by June, 2006. The vessel, a former exploration industry multi-streamer seismic ship, will be equipped with a 1° X 1° multibeam system and have the ability to deploy and recover large numbers of ocean bottom seismometers. Detailed information about the Langseth's new systems is available on the Lamont-Doherty Earth Observatory website, along with important information for anyone wishing to request shiptime on the new vessel.
