The Applied Physics Laboratory/Polar Science Center at the University of Washington has issued an extra release of Pan-Arctic Ice Ocean Modeling and Assimilation System (PIOMAS) data.
Sea ice volume on August 25th, 2012, was 3500 km3, or about 500 km3 less than the prior minimum, reached on September 10th, 2011.
The image below shows that recent data for 2012 appear to match almost perfectly the expected values based on exponential trends added by Wipneus.
Wipneus for each month of the year. The black line shows the average for the month September, pointing at zero a bit into the year 2015, while the average for August and October (the overlapping red and dark blue lines, appearing as a single purple line) point at zero before the start of the year 2016.
And, events may unfold even more rapidly, as discussed earlier at Getting the picture.
The image below, from the Naval Research Laboratory, shows the dramatic decline of sea ice thickness over the last 30 days.
