Back on the ship, chief remotely operated vehicle (ROV) pilot Aggelos Mallios maneuvers the ROV Super Achilles over unusual sediment mounds observed during the beginning of the dive. Super Achilles sent live video of the site to scientists stationed on board the research vessel Aegaeo to communicate dive plans and sampling strategy in real-time to the human-occupied vehicle (HOV) Thetis.
