  1. Surprising that MASIE keeps showing declining extent, drawing close to NOAA results.

    Day 258: MASIE shows another sizeable loss of 56,257 Km2 for a new 2014 minimum of 5.22 M Km2, or 33.6% of March max.

    Losses were widespread with new 2014 minimums in several regions: Chukchi, East Siberian, Laptev, Kara, Canadian Archipelago, Central Arctic.

    MASIE extent is still higher than NOAA at 5.02 M Km2 on day 258.

    1. Dave, good question. MASIE shows almost 24,000 Km2 lost; you’d think that a loss of 6% of that region’s ice would be noticeable.
