Whew, sorry for the false alarm, everyone. Another beginner mistake. That did seem a rather spectacular way for the breakup to begin, but with occasional ice movement in the Lincoln lately, it did seem possible.
Otherwise, ice has been getting blue around the margins of of Nares but still seems solidly white up and down most of the length, hm? I try to resist making predictions but I sure like to watch. It also seems that as the warmup progresses, some patches darken in the radar images. I make guesses, but I really have no idea what it means.
