Glaciologist Dr Richard Bates, of the Scottish Oceans Institute at the University of St. Andrews, takes 'casts' of temperature pressure current and salinity at the 'whirlpool' and crack at 80° 57'28" N and 61°20'10" W on the Petermann glacier. Dr Bates makes casts -dropping a CTD probe (Conductivity Temp Depth) into the pool 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, current strength and direction in the pool, within the glacier. This will give a data set that describes the oceanic conditions at the time that the Petermann glacier disintegrates.
