Exploring the Ocean with Robots and Submarines
To explore the deep ocean, scientists rely on numerous pieces of high-tech equipment. This photo gallery showcases some of the remotely operated vehicles (ROVs), submersibles, and other devices that have been used. Read about the Scarlet Knight, the first underwater robotic vehicle to cross an ocean.

ROV Recovers Volcano Monitor

The station was set up to study geological, chemical, and biological interactions along the mid-ocean ridge system. ROPOS can now be seen in Sant Ocean Hall.
Launch of an Autonomous Benthic Explorer

Hybrid Vehicle Nereus

That makes the remotely operated Nereus the deepest-diving vehicle currently in service.
