The Research Vessel (R/V) Thomas G. Thompson works throughout the world’s ocean basins and is the vessel being used for this node survey cruise of the Ocean Observatories Initiative.
Operated by the University of Washington
The R/V Thomas G. Thompson is owned by the Office of Naval Research and is operated by the University of Washington's School of Oceanography. The vessel is 274 feet long and has 22 crew members and officers. In addition 36 scientists and 2 marine technicians can be taken aboard for research expeditions.
Similar to a Small City
The Thompson is similar to a small city in that it is self contained with food stores that can supply the crew for > 45 days, desalinators that produce 8,000 gallons of fresh water each day, and generators that produce power to run the ship, provide lighting, and power for laboratories, communications, and navigation equipment. It uses the Global Positioning System (GPS) integrated with dynamic positioning (DP) to hold station within 1-2 meters.
On this cruise, the Thompson is host to Sentry, the newest of the U.S. Deep Submergence Facility’s autonomous underwater vehicles, and Jason to accomplish highly detailed mapping of the areas around the node sites for Hydrate Ridge, Axial Volcano, and the Coastal and Global Scale Nodes Endurance Array Lines. The Thompson’s hull-mounted EM300 sonar system will also be used for mapping and is capable of producing high-resolution bathymetric maps while steaming at 8-12 knots.
