NSIDC Total Area as at 3 August (5 day trailing average) = 4,593,103 km2
This is 208 241 251 k above the 2010-2017 average area Posted by: Thawing Thunder

I won't be making a vote on the minimum until the last moment. Breathlessly awaiting PIOMAS volume for July.
I suppose the June volume data didn't clarify much your doubts, Gero. To me at least it seems we're still sticking in a highly volatile, contradictory and uncertain season.
Too right, confusion reigns - up, down, sideways.
Area loss 3 Aug 57k,
Extent loss 2 Aug (5 day average) 91k,
Extent GAIN 2 Aug (daily) 14k, loss 3 Aug 115k
Total Area loss 57 K, Central Seas loss 47 k, Periphery loss 8 k, Other Seas loss 2 k Analysis of individual seas.
Pacific Side- The Bering Sea - finished,
- Chukchi Sea loss 4 k, area is now well below the 2010's average,
Atlantic Side- Baffin Sea loss 3 k, area 49k - less than 5% of 1980's average maximum,
- Greenland Sea loss 4 k,
- Barents Sea - finished,
- The Kara Sea area loss 4 k, area is now at 46 k, 5% of 1980's average maximum.
- The Laptev Sea area loss 5 k.
CAB- Beaufort Sea loss 21 k,
- The Central Arctic Sea LOSS 13 k,
- The Canadian Archipelago loss 0 k,
- East Siberian Sea loss 0 k .
Other seas- St Lawrence -finished,
- Hudson Bay area loss 2 k, Area now 63 k and just about at average.
- The Okhotsk Sea - finished.
On average, this is when daily
area loss declines sharply This area loss of 57 k is 10 k below this day's 2010's average. The
5 day trailing average extent loss in contrast averaged over 100k per day for the last five days (5 day average eliminates most of the ups and downs of daily extent measures and the monthly adjustments). But daily extent rose by 14k on the 2nd August but fell by 115k on the 3 August. Extent losses are still catching up with area losses again.
Qu1. The question is - will above average area losses follow the big NSIDC daily extent losses ? Not on July 31 or August 1 & 2 & 3, that's for sure.
Qu2. How low will Greenland Sea Ice Area go ? If export of ice down the FRAM strait is finished for this season (see Wipneus fram strait animation on PIOMAS August thread) and that warmth keeps drifting up from the Atlantic (that blocking high from Western Europe across the Atlantic is liable to stay there for some time) then....
