E/V Nautilus

Exploration Vessel (E/V) Nautilus is an efficient 64-meter exploration vessel with berthing for 17 permanent crew members in addition to 31 berths for members of the rotating Corps of Exploration. The ship is equipped with a Kongsberg EM302 multibeam echosounder and two remotely operated vehicles (ROVs), Hercules and Argus. E/V Nautilus has a data lab and wet lab for processing digital data and physical samples. As part of the Ocean Exploration Trust’s effort to share expeditions with students, public audiences, and colleagues, we utilize telepresence technology to stream live video from the ROVs and various locations aboard the ship in real time to the Nautilus Live website.
