The Kraken2 (K2) - is a 1000 meter light work class ROV that has been highly modified to provide power and telemetry for a variety of imaging and sampling systems. This system operates with an electo-optic tether and can support two simultaneous high definition camera and up to four standard definition cameras. The K2 also has a 6 function robotic arm, an extensible, insulated biobox and an suction sample system with eight buckets for sample collection.

Jason is a 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. Jason's manipulator arms collect samples of rock, sediment, or marine life and place them in the vehicle's basket or on "elevator" platforms that float heavier loads to the surface. Pilots and scientists work from a control room on the ship to monitor Jason's instruments and video while maneuvering the vehicle. The average Jason dive lasts one to two days, though operators have kept the vehicle down for as long as seven days.
