Remotely Operated Vehicle (ROV)
Researchers wanted an easily maneuverable, unmanned system able to venture into areas too unsafe or small for traditional submersibles. The idea for a Jason/Argo system was born. The first vehicle created was Jason Jr., a smaller prototype of what Jason was to become. This remotely operated vehicle (ROV) was attached to ALVIN and tested in the mid-1980s during the exploration of the Titanic wreck. Cables attached Jason Jr. to ALVIN where its occupants could control each movement of Jason Jr. Today, the system has three vehicles: Jason, Medea and Argo-II. Jason and Medea are meant to operate together: Medea surveying a wide area while Jason images and samples a smaller area. They can travel up to (19,684 feet) 6,000 meters depth. Argo-II is meant to be towed about 3 to 15 meters above the ocean's bottom and can also be used at depths up to 19,684 feet (6,000 meters). A fiber optic cable attaches it to a mother ship providing power and direction to the ROV's controls.
