ROV Argus

ROV Argus was first launched in 2000 as a deep-tow system capable of diving to 6,000 meters. More recently, Argus is used in tandem with ROV Hercules, where it hovers several meters above in order to provide a bird’s-eye view of Hercules working on the seafloor. Argus is also capable of operating as a stand-alone system for large-scale deepwater survey missions.
