6 thoughts on “Biggest Ice Gain in Arctic in 140 Days

  1. You’ve got a typo, in the body you wrote Antarctic. Instead of arctic. Also, is the data DMI or nsidc?

  2. The Arctic is quite surprising this year. There is a major difference when comparing this year and last.

    As I have explained before, IMO the NIC records are more reliable during the melt season, due to passive microwave reading missing ice underneath surface meltwater.

    In 2012, NIC reported the ice extent on Aug. 26, 2012:

    8/10ths 3,557,972 sq. Km.
    Marginal zone 2,591,333 sq. Km.
    Ice Extent 6,149,305 sq. Km.

    NIC reported the 2012 minimum ice extent on Sept. 21, 2012:

    8/10ths 3,275,795 sq. Km.
    Marginal zone ,923,871 sq. Km
    Ice Extent 4,199,666 sq. Km.

    Notice that most of the ice loss from now to the minimum is the reduction of the Marginal Zone.

    Now look at this year.

    For comparison NIC reported the ice extent on Aug. 26, 2013:

    8/10ths 4,895,884 sq. Km.
    Marginal zone 1,673,110 sq. Km.
    Ice Extent 6,568,994 sq. Km.

    Not a great difference in the total, but a much larger amount of the thicker ice (8/10ths).
    And the Marginal Zone is much closer to the minimum reached last year.

    Interesting month to come. Barring another unusual storm event, the recovery this year will be amazing.
