The latest Alfred Wegener Institute sea ice concentration map shows that the Pacific side of the Central Arctic Basin is now almost completely refrozen:
On the Atlantic side of the Arctic the Kara Sea is rapidly refreezing:
However, sea ice extent in the Barents Sea and Baffin Bay are currently lowest for the date in the AMSR2 record:


Pan Arctic JAXA/ViSHOP extent is currently lowest for the date in the satellite era:
Looking at sea ice volume next, at the end of November PIOMAS volume was lowest for the date in the satellite era:
Here’s the associated sea ice thickness map:
Here too is the Alfred Wegener Institute’s CryoSat-2/Sentinel 3/SMOS Arctic sea ice thickness map at the end of November:
As you can see, the “measured” data suggests that sea ice in the central Arctic is thicker than the PIOMAS model shows:
