Weather conditions in the past month - the (Great?) Arctic Cyclone followed by the Mega-Dipole to be precise - have left a mark on volume decrease. During August 2016 more sea ice volume was lost than during any other August in the past decade, with the exception of 2008, even more than during August 2012 (2909 km3 vs 2744 km3). Just like on the area and extent graphs, 2016 is almost in second position here too, as the difference with 2011 shrunk from 621 km3 to 84 km3.
Here's how the differences with previous years have evolved from last month:
Last month I wrote:
There is a lot of melting potential in the East Siberian Sea region, extending into the Central Arctic, that could make this year end up close to the 2011 minimum, which is second lowest after the 2012 record lowest minimum.
We now know that melting has been massive in this region, as can be seen on this Uni Bremen SIC maps animation, showing the spectacular changes from August 2nd to September 2nd, the main reason for the significant volume drop:
Wipneus' version of the PIOMAS volume graph also clearly shows that this year's trend line dropped a bit faster, breezed past 2010 and is now almost at a par with 2011:
