A couple areas that are noteworthy today.
Indeed. The Kara is just getting hammered and will continue to be for at least the next 10 days. The Hudson starting to come apart is a little unexpected, and not at the same time. Ice there in spite of recent cold temperatures has never had a chance to really set up and is quite a bit less solid and less thick than I've seen previously (which admittedly is only 5 years...).
Both breaking open will increase insolation uptake at a point very early in the melt season.
It implication of that from the Hudson is not that great. Ice leaving the Kara is much more troublesome, as it will introduce heat at high latitude and eliminate ice which buttresses both the CAB and Laptev. Admittedly the Barentsz is more important for the CAB, but it all works together, and without some integration we will see albedo reductions in the high arctic even with out melt ponds, as peripheral ice melts, and permits the main pack to disperse.
