Temperature and salinity profiles obtained from the CTD-casts reveal distinct
differences between the Porcupine Seabight and the eastern Rockall Trough. The
thermocline in the Rockall Trough is at approximately 60m and at approximately 90m
in the Porcupine Seabight.

The Porcupine Seabight thermocline is less well developed. The intermediate water
masses are more variable in the Rockall Trough, while in the Porcupine Seabight they
only occur below 500m water depth.
