Two-body ROV system. A 10-kilometer (6-mile) reinforced fiber-optic cable delivers electrical power and commands from the ship through Medea and down to Jason, which then returns data and live video imagery. Medea serves as a shock absorber, buffering Jason from the movements of the ship, while providing lighting and a bird’s eye view of the ROV during seafloor operations. Jason is equipped with sonars, video and still imaging systems, lighting, and numerous sampling systems.
