E/V Nautilus
Nautilus is an efficient 64-meter exploration vessel with
17 permanent crew and berthing for a 31-member rotating
Corps of Exploration. The ship is equipped with a Kongsberg
EM 302 multibeam echosounder and two ROVs named
Hercules and Argus that explore the seafloor. The ship has a
data lab and wet lab, as well as other scientific facilities, for
processing digital data and physical samples. As part of our
effort to share our expeditions with students and colleagues,
we use telepresence technology to stream live video from our
ROVs and various locations on the ship in real time to our
Nautilus Live website (http://www.nautiluslive.org).
