The 2021 Maximum Arctic Sea Ice Volume

If the 2021 maximum Arctic sea ice extent is more your thing then please see the previous article:

The 2021 Maximum Arctic Sea Ice Extent

Maximum volume is still several weeks away, but let’s first of all take a look at the PIOMAS modelled volume numbers for February. They are not yet available via the University of Washington’s Polar Science Center web site, but Wipneus has once again crunched the gridded thickness numbers which are already available. Here is what they reveal:

Facts About the Arctic in July 2019

The June PIOMAS Arctic sea ice gridded thickness numbers have been released. Here once again is Wipneus’ visualisation thereof:

The Arctic wide volume graph does not make a pretty sight:

The recent rapid rate of decline has continued through the second half of June and PIOMAS modelled volume is now lowest for the date in the Polar Science Center’s records.

Facts About the Arctic in March 2019

Wipneus has recently updated the mid month PIOMAS gridded thickness map, which looks like this:

The accompanying PIOMAS volume graph currently shows 2019 in seventh place:

We now have a new thickness metric to peruse each month. Here’s the gridded merged CryoSat-2/SMOS thickness data from the Finnish Meteorological Institute:

Facts About the Arctic in October 2018

A somewhat belated start to our October 2018 coverage, but firstly please take a look at this graph:

Following a remarkably sluggish refreeze this year JAXA extent is currently the lowest for the date since their records began. Meanwhile Wipneus has just released his mid month PIOMAS volume update on the Arctic Sea Ice Forum:

The 2017/18 Festive Season in the Arctic

Christmas is coming, and Santa’s secret summer swimming pool has frozen over once again. However the same can’t be said for the Chukchi Sea! More on that in due course, but first let’s take a look at the PIOMAS volume graph at the end of November, courtesy of the wondrous Wipneus on the Arctic Sea Ice Forum:

Facts About the Arctic in August 2017

What seems likely to be the most interesting period of the 2017 Arctic sea ice melting season is upon us! The PIOMAS gridded data hasn’t been released yet, but the overall volume numbers reveal that 2017 has now relinquished its “lowest ever” position to 2012. Here’s Wipneus’ graph of the volume data:
