The "all-time" minimum Antarctic sea-ice looks to be later Feb 2017,
stood at 2.411 m sq km yesterday so 121,000 sq km above that 27 Feb 1997
record as of yesterday .
Same figure as yesterday, something broken away compensating for normal
ice loss? perhaps a larger than recent daily depletion figure tomorrow,
ie difference between are and extent determination


The NPIR chart from Japan has been showing a daily decrease of 0.01 M sq km over the last few days, compared with 0.1 M sq km per day during January. https://ads.nipr.ac.jp/vishop/#/extent

Their Antarctic sea ice extent actually increased yesterday. Just another example of the chaotic nature of sea ice extent!
