 Laura Kracker, a geographer for NOAA in Charleston, SC, and Andy David, chief scientist for the Extreme Coral 2011 expedition, survey 
data on computer screens in the acoustics lab.  These data will be used to map the ocean floor and 
determine the best locations to search for the Lophelia corals.

A row of life jackets waiting to be used. 
 
 Safety is paramount on board the Pisces.  Everyone outside must wear a life preserver when work is being conducted over the side of the ship.  These are neatly hung near the exit to the crane deck 
where the ROV will be launched.  People on deck also must wear a helmet if equipment is being lifted overhead by the crane.

ROV, tethered to 40 meters of cable, prepares to dive. 
 
 The remotely operated vehicle (ROV) has a tether with copper cable and optical fibers inside.  The copper cables supply the ROV with electricity 
and optical fibers allow communication with the ROV, and feed data and video collected by the ROV back to the ship.
