I would be very surprised if the subsurface current which flows south through the Nares ever shuts down. The phenomena that we are seeing is surface only where the winds will have an effect on the flow of ice.
Sorry, SH, i should have said surface current. That's what i'm talking about.
Of course, when the surface current stops, that doesn't mean that it also stops deeper down.
But, that the surface current stoped, is pretty evident from the GIFs i provided for this and the recent event (upthread).
If you see a current, please tell me what to look for.
