Arctic Sea Ice News & Analysis. Arctic sea ice reached its annual maximum extent on March 21, after a brief surge in extent mid-month.
Overall the 2014 Arctic maximum was the fifth lowest in the 1978 to 2014 record. Antarctic sea ice reached its annual minimum on February 23, and was the fourth highest Antarctic minimum in the satellite record. While this continues a strong pattern of greater-than-average sea ice extent in Antarctica for the past two years, Antarctic sea ice remains more variable year-to-year than the Arctic. Figure 1. Arctic sea ice extent for March 2014 was 14.80 million square kilometers (5.70 million square miles).
