National Deep Submergence Facility Vehicles
Alvin is a 3-person research submarine that takes scientists deep into the ocean. Since its launch in 1964, the Alvin has enabled more than 2,500 scientists, engineers, and observers to visit the floor of the deep sea.
Jason/Medea is a remotely operated vehicle (ROV) system designed and built by WHOI’s Deep Submergence Laboratory. A 10-kilometer (6-mile) tether relays electrical power, control signals, data and live video imagery between a surface ship and the vehicle.
The autonomous underwater vehicle (AUV) Sentry is following in the wake of its predecessor, ABE, as a fully autonomous underwater vehicle capable of exploring the ocean down to 4,500 meters (14,764 feet) depth.
