Here is an example of fast ice in Kane Basin, attached to the Humboldt Glacier front. It has been subjected to above-zero temps for a long while, and the effects are showing - breakage, melt ponds, draining of ponds, more breakage. The high temps couldn't melt it all yet, though it's quite certain it will disappear by the time the melting season ends.
The animation runs from May 16th to July 21st, skipping 3-5 days at a time except at crucial points or where clouds prevent it. Please forgive the very crude date labels.
