Originally constructed as a seismic vessel the Maurice Ewing was acquired in 1989, modified, and outfitted to perform the tasks required of a general purpose research vessel. The R/V Maurice Ewing is a 230 ft, 1978 gross ton research vessel which is owned by the National Science Foundation and operated by Lamont - Doherty Earth Observatory.

The ship is classed by the American Bureau of Shipping as A-1 Baltic Ice Class IA and certified to carry a total of 50 personnel of which approximately 20 are the ship's crew. With a cruising speed of 11 knots and an endurance of up to 60 days the Maurice Ewing has operated from the Arctic to the Antarctic, and in virtually all the world's oceans.

The R/V Maurice Ewing will serve as the seismic data collection vessel for this project.

R/V Seward Johnson II is a 168-foot former offshore supply vessel that was converted to support marine science research, ocean engineering research, and submersible operations. With a 7,000 nautical mail range and cruising speed of 11 knots, the vessel is capable of traveling to any of the world's oceans while accommodating 38 people. An 18-ton A-frame handling system located on the aft deck allows safe submersible launch and recovery up to sea state five.

The R/V Seward Johnson II will deploy and retrieve the OBS units that the Ewing will use to collect data.
