Arctic sea ice maximum at record low for third straight year

On March 7, 2017, Arctic sea ice likely reached its maximum extent for the year, at 14.42 million square kilometers (5.57 million mi2), the lowest in the 38-year satellite record. This year’s maximum extent is 1.22 million square kilometers (471,000 mi2) below 1981 to 2010 average maximum of 15.64 million square kilometers (6.04 million mi2) and 97,000 square kilometers (37,000 mi2) below the previous lowest maximum that occurred on February 25, 2015. This year’s maximum is 100,000 square kilometers (39,000 mi2) below the 2016 maximum, which is now third lowest.

Ecoclimax is defined by Odum (1969) as the culmination state after a succession in a stabilized ecosystem in which maximum biomass (or high information content) and symbiotic function among organisms is kept per unit of available energy flow.
