One thought on “Arctic Sea Ice: NSIDC vs MASIE Daily Changes”

1. Day 253 is in, showing an increase of almost 40,000 Km2, an extent matching day 248, and the first increase since day 237.

   Here are the results for regions with ice remaining:

   Region Date Reported Ann Min %of Max
   (0) Northern_Hemisphere 2014252 5445009 35.1%
   (1) Beaufort_Sea 2014246 704681 65.8%
   (2) Chukchi_Sea 2014251 277576 28.7%
   (3) East_Siberian_Sea 2014249 525410 48.3%
   (4) Laptev_Sea 2014253 1795 0.2%
   (5) Kara_Sea 2014253 88846 9.5%
   (6) Barents_Sea 2014248 121208 16.5%
   (7) Greenland_Sea 2014252 162018 21.3%
   (8) Baffin_Bay_Gulf_of_St._Lawrence 2014230 9776 0.5%
   (9) Canadian_Archipelago 2014248 487137 57.1%
   (10) Hudson_Bay 2014251 11503 0.9%
   (11) Central_Arctic 2014250 2968800 91.4%

   Note that losses in Laptev and Kara Seas were offset by gains elsewhere, especially in Beaufort, Chukchi and Greenland Seas.

   Could this be the minimum? If it holds, the 2014 minimum will be slightly less than 5.51 MKm2 in 2013. Yet, the 2014 Maximum in March was 15.52 Mkm2, compared to 2013 max of 15.65 MKm2.

   It is more obvious how exceptional was the 2012 minimum of 4.20 MKm2. That year saw a loss of 11.8 M Km2 (78% of max) compared to an average loss of 10.42 (66% of max) for all other years since 2006. The 2014 loss of 65% is close to average.

   The average Minimum for the years 2007 to 2013 inclusive is 5.15 MKm2. Excluding 2012, the average Minimum is 5.30 M Km2.
