Latest GIOMAS/PIOMAS volume data for Antarctica

[Lord M Vader]

From Wipneus page where data from GIOMAS and PIOMAS for Antarctica are available. I think it's time for a thread that looks at the volume data around Antarctica given the record low extent numbers there.

While the extent numbers currently are at a record low level I doubt that the minimum volume as well as the SIE minimum will be at record low level given that the modeled average sea ice thickness around Antarctica have had a positive upward trend wrt the ice thickness. What will determine the final outcome for this melting season is whether the sea ice in the Ross Sea will melt out or not.

The only thing I miss from Wipneus site is similar thickness maps like the one for the Arctic basin.

no redirects in image name - ie posting here gets too many views and causes problems. But there does appear to be a giomas antarctic mean thickness graph at

Thickness seems very close to record low so surely volume is record low for this time of year (were you referring to record low ever?).

Ahh, I was looking at graph of thicknesses since 2001. 1980 have lower volume anomaly but not at this time of year. 1981 at this time of year is slightly hard to judge on tale of the tape graph, but Antarctic volume is lowest or second lowest for this time of year.

GIOMAS data has been updated to 2018-12-31.

I have updated most of the graphs, let me know if there is one that I overlooked.

Even better is that daily data is now available. All the graphs are will have to be modified. It is a huge improvement but will take some time as the amount of data is causing performance problems.

The place for these graphs are (arctic and antarctic):

A few global (NH+SH) are on the global sea ice page:

Attached are Antarctic volume and volume-anomaly graphs
