Check back soon for our impressions of the first dive of the cruise. We’ll be diving at Richardson Hills and are expecting to see some spectacular coral habitats! Jason is an ROV system designed and built by WHOI’s National Deep Submergence Laboratory and funded by the National Science Foundation. Its design gives scientists access to most of the globe’s seafloor, often for days at a time, without leaving the deck of a ship. The vehicle can operate as either a two-body (with ROV Medea) or a single-body system, depending on mission requirements. A 10-kilometer (6-mile) reinforced fiber-optic cable delivers electrical power and control signals from the ship to the vehicle and returns data and live video imagery throughout a dive. When Medea is used, it acts as a “shock absorber” shielding Jason from the movement of the ship and cable. For the DEEP SEARCH mission, Jason will be operated in single-body mode with a series of floats attached to the cable to dampen the influence of the surface swell. Jason is equipped with sonars, video and still imaging systems, lighting, and a flexible payload of sensors and sampling systems. The vehicle’s manipulator arms collect samples just by picking them up, or by deploying sampling gear provided by the science team, such as push cores and mussel pots. The samples are then placed in the vehicle’s basket or on “elevator” platforms that float samples to the surface, permitting Jason to stay submerged for as much as a week at a time. language code: en);
