________________________________________
Only two of the central seas still of interest
- Kara Sea, freeze rushing to com,pletion,
- Central Arctic still losing extent and area from NE Greenland to North of Svalbard .
Not long for attnetion to switch almost entirely to theperipheral seas for extent and area - (but PIOMAS volume becomes even more relevant for all seas).
