30 | Cruise Report, RV ATAIR, Cruise 0671013-1, Bremerhaven - Skagen - Aberdeen, 19 Jul - 11 Aug 2022

Deviations in temperature from the long-term mean (Figure 6.3, right) reveal warmer conditions,
 particularly off and along the east coast of the UK and in the western and southwestern
varts of the North Sea. The location of the warmest temperature deviation observed in the CTD
data at 5 dbar corresponds with that seen in the SST anomaly distribution (Figure 6.1)
Stronger cooling was observed off the western Danish coast, extending into the central North
Sea, along 60°N, and over the Norwegian Trench.
