It was never so easy to detect the Beaufort Gyre and its clockwise rotation on satellite images. Whether winter ice is now that thin it can't stand usual weather forces or the weather changed remains to be determined.
Cracks with an irregular stress pattern are common in the Arctic - the floes are constantly moving, but this distinct pattern is visible up to North Pole. Fore sure, weeks after melting starts, we'll see an even more unknown pattern of floes. I expect unusual noisy extent charts, too.
