Yes, that would be the 3rd lift-off this season due to strong westward zonal winds of 45-85 km/hr (if we are looking at the same thing, hollow arrow) but the overall appearance above Morris Jesup is oddly fractured. Thing to do here is look at it through various channels to get at recent history at assorted wavelengths. This is day 5 of this event which will continue to the 24th.
It can cause double-counting of Fram export to the extent ice is blown back and forth across the flux gate (taken as 82ºN below) before getting caught up for good in the East Greenland Current and melted out to the south.

Ice volume export drives variations of Arctic ice mass balance. It also represents a significant fresh water input to the North Atlantic, which could in turn modulate the intensity of the thermohaline circulation.
We present the first estimates of winter sea ice volume export through the Fram Strait using CryoSat-2 sea ice thickness retrievals and three different drift products for the years 2010 to 2017. The export rates vary between 21 and 540 km
3 per month.
We find that ice drift variability is the main driver of annual and interannual ice volume export variability, and that the interannual variations of the ice drift are driven by large scale variability of the atmospheric circulation captured by the Arctic Oscillation and North Atlantic Oscillation indices.
On shorter timescale, however, the seasonal cycle is also driven by the mean thickness of exported sea ice, typically peaking in March. Considering Arctic winter multiyear ice volume changes, 54 % of the variability can be explained by the variations of ice volume export through the Fram Strait.
