Arctic Ice Power Mid March

Previous posts showed 2020 Arctic Ice breaking the 15M km2 while questioning whether the ice has staying power.  “Yes” is the answer, at leat through the first third of March.

 

By end of February, ice extent this year was well above the 13- year average, then dipped lower before growing again surplus to average and other recent years.  This is important since March monthly average is considered the ice extent maximum for the year. Note also the SII is matching and currently exceeding the MASIE estimates.

The chart below show the distribution of ice across the various regions comprising the Arctic zone.

As of yesterday, Day 2020071 matches the NH 13-year average and also most regions.  Two deficits to average are in Baffin Bay and Baltic Sea, offset by surpluses in Bering and Okhotsk, as well as Central Arctic and Barents Sea.
