Bering Sea between Russia and former Russian clay sold to the USA has a record low ice extension for this time of the year since they started recording it.
Linked to it is Alaska that suffers from a heatwave pretty much the whole winter. The frozen rivers are already unusable to drive on. Good news for crabs though:
>Crab fishing has also been affected as the sea ice used as a platform for fishermen was non-existent or too thin in some areas.
