Here's a visible image from Friday afternoon from the
Suomi NPP satellite. With clear skies over much of mainland Alaska, there's a lot of detail to be seen. Note the area of open water west of Barrow. It's small, but the fact that there's more than a lead is quite remarkable for mid-March. Also note that many areas in Interior Alaska are fairly dark, which of course is simply the boreal forest. This difference in albedo on land is a major factor in show fast it warms up in the spring in Alaska.
Here's an informative website about the Arctic sea ice. Note the section regarding the fractures. May be connected to Rick's recent observation near Barrow.
