Vertical profiles of ocean temperature
Vertical profiles of ocean temperature show that it clearly increases in the first 800-1000m (maximum increase at 200m) in the wide domain experiments in both the Atlantic part of the Arctic Ocean (first figure below) and the Pacific part of the Arctic Ocean (second figure below). This suggests that the ocean heat propagates through the whole Arctic in both the North Atlantic and North Pacific experiments. While the temperature increase is less pronounced in the middle and small domain experiments, there is also suggestion of heat propagation through the Arctic Ocean.
