On average, this is when daily area loss declines sharply and wobbles from day to day. The area loss of 33 k is below average by 5k for this day. Extent loss (also 5-day trailing average)) was up at 55k, aboveaverage for the day. But daily extent loss was 87k after an impressive 139k and before a series of very low losses - 12 k, 10k, 24k, and 5k the days before. End of season wobbles.
It is all about the 4 central seas now. The melting season ain't over yet, there is a chorus of fat ladies waiting in the wings for a chance to sing, but I think one just left, or did she come back again, and left again..
ps: Laptev area loss still going down. Seems to be part of that Atlantic front highlighted by Zlabe.
