Behind all of my blogging on sea ice is the volume loss, which is driving the changes. The volume loss is shown by other data (e.g. Submarine upward looking sonar, ICESat, IceBridge, Cryosat 2), but the most detailed picture is that provided by PIOMAS. What is driving the volume loss in PIOMAS and is this process at work in reality?

What is the link between the thinning of Arctic Sea ice and the increased open water seen in recent years?
Saturday 15 March 2014
PIOMAS gridded data has been released for February giving some more detail about current ice state. The peak volume for the whole Arctic is in April, thickening continues in the central Arctic into May, so there is still time for thickening but I don't expect the volume to reach the high level compared to last year. The 2013 volume pulse seems to be largely spent.
