UW has updated its PIOMAS sat estimate of Arctic seaice volume to the
end of May. They find May averaged around 21520 km3, ranking
7th-lowest in the modern record.

The YTD avg seaice is ~20080 km3 raking 3rd lowest for the period.

Combining PIOMAS and NASA's estimate of seaice extent gives an avg
Arctic thickness of around 1.7m for the month, ranking 4th-lowest in
the dataset. May Arctic seaice is currently thinning around 1.7 cm/yr.

The YTD avg thickness is around 1.46m ranking 5th lowest in the sat era.
