NUI Galway Cruise Stations 2015

147 stations including CTD, zooplankton Net, XBT, MultiNet, Argo Float, ADCP and Trawl taken on board RV Celtic Explorer cruise in April-May 2015 during the Biodiscovery and deep ocean ecosystems 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). The Plankton net is a funnel-shaped, fine-meshed net that is towed through the water. The net concentrates the Plankton from hundreds of gallons of water that pass through it. A simple net can be constructed to capture microscopic Plankton. 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.
