(Bob Vergaras/A.P.S. for Lamont Doherty Earth Observatory)Marine scientists are bracing for the loss of the world-class research vessel Marcus G. Langseth. The National Science Foundation plans to sell the 235-foot ship in 2020, according to a "Dear Colleague" letter published on the agency's website last month. Without a vessel to replace the Langseth, ocean seismologists fear their field will suffer.
“We’re not trying to save the Langseth at all costs,†said
James Austin, a geoscientist at the University of Texas at Austin. “We’re trying to save deep-ocean crustal imaging.â€
Deep-ocean crustal imaging is where the Langseth excels. It is no ordinary ship. Its sophisticated array of
pneumatic guns generates a blast that bounces off the Earth's crust and penetrates
dozens of miles into the planet. Unspooled behind the ship, miles of cables strung with microphones capture the blast's reflection. This sonic bounce creates maps of mid-ocean-ridge magma chambers and tectonic plate edges, features that are otherwise difficult, if not impossible, to survey.
“There really aren't any comparable vessels that are available to academic scientists,†said geophysicist
Douglas Wiens, a professor at Washington University in St. Louis and chair of the Iris Consortium, a network of 100-plus universities that collect seismological data.
