Actually the many Ascat animations posted earlier best capture the ice motion from Oct 15 to May 15, that's why we enhance them rather than use secondary low resolution products that don't allow ice feature tracking or delaunay shape change quantitation.
More recently, there's been some question of extraordinary melt atlantification of the Atlantic side (largely decoupled from shelf bathymetry) vs the wind simply blowing the ice pack north and west. The time series below suggests some of both but going by the arrows, feature conservation, lack of compactification and 5dp GPS of the newly moored Polarstern buoys, it was mainly just the wind.
Thus this is different from the massive opening north of Greenland which the Polarstern's captain correctly described as ice melt from the extraordinary heat wave (documented at Alert and Morris Jessup wx stations), rather than bulk pack advection towards the NSI creating open water gaps.
Regardless of how it got there, the largely unprecedented position of the ice pack today has many implications for the coming freeze season in terms of surface mixing of areas usually ice covered, possible lateral extension of long term atlantification, winter Fram export, and reduced Barents stratificational maintenance.
The Atlantic side has had a much more orderly progression than the Beaufort-Chukchi (which got just hammered in late July by an anti-cyclone). For clarity, the shrinkage is shown in a matched-pair palette created for this type of adjacency map at Colorbrewer2 (and used to good effect on NOAA-PSL maps). The AMSR2_UHH are set 4 days apart which surprisingly provides enough spacing. They are flipped horizontally so the two views face each other to bring matching areas visually closer.
