I have made another animation for May which surprised me with a smaller area export.
Northern edge of the marked floes on 2. April was 82.9N i.e. 322km from their position on 2. May (the date chosen for visibility)
The marked area is 136500 square km
I have marked points which do not lie on the 80N parallel on 2. 5. because I wanted to see what happens between the converging floes.
It would be interesting to look at the area north of Svalbard where ice is compacting and PIOMAS and Cryosat are showing thickness anomalies but it is difficult to track floes there, the compaction it seems makes it look more amorphous in the AMSR images (weather effects are not helping either)
Svalbard has seen snowfalls in April, possibly that area too?
This of course is area I would expect volume exported to be larger because thicker ice is leaving, and that is shown by Wipneus in the PIOMAS thread.
