- Fig. 1: the mean Atlantic OHT increases north of 60N and decreases south of 60N compared to the control run in the experiments where the SST restoring is imposed in the North Atlantic and northern North Atlantic (no clear change with the restoring occurring only at the BSO); the OHT increase north of 60N is logical as the SST is getting warmer; the reason for the decrease south of 60N is probably linked to a weakening of the ocean circulation at latitudes lower than 60N following the increase in SST (so decrease in density) (see Fig. 8);

|
- Fig. 2: the total OHT to the Arctic through all Arctic straits (BSO, Fram, Bering, Davis) clearly increases with increasing SST; the strength of the increase in OHT increases with higher SST increase and is clearly higher with the North Atlantic domain compared to the 2 other domains; with the BSO domain, the OHT increase is relatively small; so the higher the domain for the SST increase, the higher the resulting OHT increase;

- Fig. 3: this is the OHT through the BSO, which is the most important OHT contributor to the Arctic; results are broadly consistent with Fig. 2, except that the increase in OHT does not linearly increase with the increase in SST when the BSO domain (smallest domain) is considered;
|
|
|
- Fig. 4: there is an OHT increase at Fram Strait with SST when using the 2 first (larger) domains and not really when using the BSO domain; however, the strength of the OHT increase is much lower than for the OHT through the BSO;

- the OHT at the Bering Strait also increases with increasing SST for all 3 domains, but the strength of the
