ROV (Towsled) Atalanta

ROV Atalanta
Ocean Exploration Trust

Atalanta was first launched in 2019 and is a smaller version of Argus used in tandem with ROVs Little Hercules or Hercules, where it hovers several meters above in order to provide a bird’s-eye view of the ROV working on the seafloor. Atalanta is also capable of operating as a stand-alone system for wider-scale deepwater survey missions or as a sled for towed sensors like sidescan sonars.
