Relative contributions from winds and thermal forcing
I find this section very convincing!
One additional suggestion, still. What do the sea ice area export curves look like in the FESOM simulations? I am assuming that if you were to look at area export (function of ice drift and ice concentration), you would get a similar picture to Fig. 3c - i.e.: slightly positive trends, with the variability almost entirely explained by winds. Is it possible to show that (additional panel in Fig. 3)? I believe it would bring yet an another argument supporting that the long term trend in volume export has to be thickness driven.
