The most interesting area is Beaufort to Bering sea:
July 4 to 20 2012, there was more open water over Beaufort because the Gyre circulation was largely unaffected by cyclones till August. Note the ice pans maintaining about 100 km in diameter, moving clockwise.
The Atlantic front difference is fascinating as well,
|Atlantic Front July 17 2012, note the ice shoreline hugging Franz Josef and Svalbard Islands,|
|There is at present about a 250 km retreat towards the Pole for the entire Atlantic Front.|
