How about extreme winds compacting the existing ice sheet? The atmospheric temperature has dropped below 267K [ -6C ] -> http://ocean.dmi.dk/arctic/meant80n.uk.php . The Sun is nearly beneath the horizon. The Ocean temperatures are dropping -> http://ocean.dmi.dk/arctic/satellite/index.uk.php .
Supposedly MASIE is better at some things.

Surprising that MASIE keeps showing declining extent, drawing close to NOAA results.
Day 258: MASIE shows another sizeable loss of 56,257 Km2 for a new 2014 minimum of 5.22 M Km2, or 33.6% of March max.
Losses were widespread with new 2014 minimums in several regions: Chukchi, East Siberian, Laptev, Kara, Canadian Archipelago, Central Arctic.
MASIE extent is still higher than NOAA at 5.02 M Km2 on day 258.

I’m not seeing huge losses on the Canadian Ice Service maps for Canadian Archipelago between sep 14 and 15. Wonder who is right?

Dave, good question. MASIE shows almost 24,000 Km2 lost; you’d think that a loss of 6% of that region’s ice would be noticeable.
Arctic sea is has started to reform. Latest sat picture shows new sea ice forming. All the ice tat did not melt is now multi year ice.
