Nares export is not significant enough to make much of a dent in a new record. 2019 export started in April, and did not have many episodes of reverse wind as this year, which started export only in early July. It's important for the thick ice in the Lincoln Sea, and impacts volume and long-term stability of the ice pack, but is not a short term game changer.
This year we have the floes that broke off from the northern Greenland coast and are swirling around in the Lincoln Sea. I am quite interested to see their fate, and have a private bet with myself that even the very large one (top left in the animation) will be sucked down the Nares this month, even though it was shifted slightly away from the "Nares envelope" by the previous up-wind event. When the wind joins the natural current and both are heading south, the envelope expands dramatically. This of course depends on how long the wind will blow down the strait before subsiding or even reversing again.
