Update 20140625.
Extent: -87k7 (-607k vs 2013, +295k vs 2012)
Area: -53k8 (-572k vs 2013, +121k vs 2012)
Continuing declines, but not as big as 2012 and 2013 on this day. Considering extent, about half the loss is in the Arctic Basin, mostly Kara and Barents. Decline in the CAB is caused by extending the various open waters (polynya) in ESS, Laptev, Kara and Barents sections into the CAB area.
Considering area, there is very little net decline when Hudson, Baffin and Greenland Sea are not included. In Kara there is a big decline, almost matched by an increase in the Canadian Archipelago. .
