Seems the June melt pond fraction may be higher this year than it's been for a while.

How did the June melt pond fraction look like back in 2007-2008, 2010-2012 and 2016?

Wipneus' graphs based on JAXA AMSR2 data suggest that surface melting has been below average in the last few weeks, compared to previous years.

As expected the fast ice has reappeared in the Laptev Sea. The "torching" expands to the ESS, where some curious scribbles can now be seen. Frozen leads was the best explanation if I remember correctly.

Thank you Wipneus. I consider your animated images of regions in the Arctic some of the most informative posts when it comes to tracking the melt season. Don't feel the need to match the volume of posts you have done in the past but occasionally zeroing in on regions of interest or rapid change is very much appreciated.

Update of the Jaxa AMSR2 sea ice thickness/melt animation. During the melting season thickness is rather without meaning, but the melting area should be interesting.

Here I combine the Ascending and Descending data: in melting if detected in either, else average thicknesses.
