JAXA ANTARCTIC SEA ICE EXTENT:  5,988,046 KM2 as at 04-Apr-2021

- Extent gain on this day 67k, 25 k less than the average gain on this day (of the last 10 years) of 92k,
- Extent gain from minimum on this date is 3.20 million km2, 0.47 million km2, (17.0%) more than the 10 year average of 2.74 million km2.
- Extent is 31 lowest in the satellite record of which 17 lower values are in the years before 2000

- Extent is  789 k LESS than 2015
- Extent is  1,889 k MORE than 2017
- Extent is  1,177 k MORE than 2006
- Extent is  454 k MORE than 2020
- Extent is  616 k LESS than the 1980's Average

- On average  20.0% of ice gain from minimum to maximum done, and 171 days to maximum

Projections. (Table JAXA-Ant1)

Average remaining freeze (of the last 10 years) would produce a maximum in Sept 2020 of 19.23 million km2, 1.17 million km2 above the 2017 record low maximum of 18.06 million km2.

JAXA ANTARCTIC SEA ICE EXTENT:  6,030,690 KM2 as at 05-Apr-2021

- Extent gain on this day 43k, 50 k less than the average gain on this day (of the last 10 years) of 93k,
- Extent gain from minimum on this date is 3.24 million km2, 0.41 million km2, (14.7%) more than the 10 year average of 2.83 million km2.
- Extent is 27th lowest in the satellite record of which 14 lower values are in the years before 2000

- Extent is  829 k LESS than 2015
- Extent is  1,806 k MORE than 2017
- Extent is  1,160 k MORE than 2006
- Extent is  446 k MORE than 2020
- Extent is  562 k LESS than the 1980's Average

- On average  20.3% of ice gain from minimum to maximum done, and 170 days to maximum

Projections. (Table JAXA-Ant1)

Average remaining freeze (of the last 10 years) would produce a maximum in Sept 2020 of 19.18 million km2, 1.12 million km2 above the 2017 record low maximum of 18.06 million km2.
___________________________________________________________
2 days of lower than average sea ice extent gains and sea ice extent changes from 31st to 27th lowest - shows how tightly packed is the Peloton.

___________________________________________________________
6 days of somewhat below average daily sea ice extent gains start to meke a difference. Extent has changed from 31st to 25th lowest in the 43 year satellite record in those 6 days.
