45 stations including CTD, CTD-SAPS and ROV, taken on board RV Celtic Explorer cruise CE14009 in June 2014 during the Ecosystem functioning and biodiversity at Whittard Canyon Survey. A large instrument package called a CTD is the standard workhorse of oceanographers for acquiring water column profiles. It is called a CTD because as a minimum it measures electrical Conductivity, Temperature, and Depth (pressure). A remotely operated vehicle (ROV) is an unoccupied underwater robot that is connected to a ship by a series of cables. These cables transmit command and control signals between the operator and the ROV, allowing remote navigation of the vehicle.
