The CTD (Conductivity Temp Depth) probe in use by Geophysicist Dr Richard Bates, of the Scottish Oceans Institute at the University of St. Andrews, in Petermann Fjord. Dr Bates makes 'casts' by dropping the CTD probe into the fjord and pulling it back up at a slow speed. The data recorded by the probe is later downloaded into computer software plotting accurate measurements of water temperature, salinity, turbidity (how turbulent the water is), current strength and direction at the front of Petermann glacier. This will give a data set that describes the oceanic conditions at the time that the Petermann glacier disintegrates.
