Jason (ROV)
 Jason is a remotely operated vehicle (ROV) designed and built by WHOI’s Deep Submergence Laboratory to allow scientists to have access to the seafloor without leaving the deck of a ship.Jason is a two-body ROV system. A 10-kilometer (6-mile) electro-optical-mechanical tether delivers electrical power and commands from the ship through Medea and down to Jason which then returns data and live video imagery.
