Interesting bit on the Squam link. However, it really only explains density differences in the liquid phase. Years ago when I was scuba diving off Cow it was shocking how cold the water was at about 50 feet. Even in a 1/4" wetsuit it was nearly unbearable. I'd say about 40 degrees in July. These thermoclines are significant.

Anyway, I've always thought it was as several of you said, a thin layer of water trapped on top of the remaining ice, giving the appearance of "sinking" ice.

Thanks......
