JAXA ARCTIC SEA ICE EXTENT: 11,989,519 KM2 as at 06-Jan-2025
The very high sea ice gain on this day maybe linked to very cold weather in Eastern North America (i.e. in Hudson Bay, Baffin Bay and St Lawrence)?.
- Extent gain on this day 121k which is 74 k more than the average gain on this day (of the last 10 years) of 47k,
- Extent gain from minimum on this date is 7,917 k, which is 371 k, 4.5% less than the 10 year average of 8,288 k.
- Extent is 1st lowest in the 47 year satellite record. Extent has been lowest for 6 days so far this year.
- Extent is 1,074 k LESS than 2024,
- Extent is 473 k LESS than 2023,
- Extent is 953 k LESS than 2022,
- Extent is 399 k LESS than 2021,
- Extent is 632 k LESS than 2020,
- Extent is 178 k LESS than 2018,
- Extent is 400 k LESS than 2017
- Extent is 845 k LESS than 2012
- Extent is 2,112 k LESS than the 1980’s Average
- Extent is 572 k LESS than the 2010's Average.
On average 84.2% of extent gains from minimum to maximum done, and 56 days to the average date of the maximum.
Projections. (Table JAXA-Arc1)
Average remaining extent gain (of the last 10 years) would produce a maximum in March 2025 of 13.55 million km2, 0.33 million km2 below the March 2017 record low maximum of 13.88 million km2, which would be 1st lowest in the 47 year satellite record.
