Ah, I remembered. Between "pre" tags, the alignment is preserved. Area: Arctic Basin East Siberian Sea Laptev Sea -16.3 0.6 -7.4 Kara Sea Barents Sea Greenland Sea -22.4 -17.0 4.0 Baffin/Newfoundland Bay St. Lawrence Hudson Bay 11.6 -14.7 -41.1 Canadian Archipelago Beaufort Sea Chukchi Sea 3.3 2.2 3.4 Bering Sea Sea of Okhotsk Total Area -3.7 -58.7 -156.4

Your calculations are very helpful, but for the 174K drop, could you please share from NSIDC where this drop is happening? The opportunity to quote the exact values per region has gone (overwritten by totday's update). Here are some numbers from from area, calculated the NSIDC way: Area: Arctic Basin East Siberian Sea Laptev Sea -16.3 0.6 -7.4 Kara Sea Barents Sea Greenland Sea -22.4 -17.0 4.0 Baffin/Newfoundland Bay St. Lawrence Hudson Bay 11.6 -14.7 -41.1 Canadian Archipelago Beaufort Sea Chukchi Sea 3.3 2.2 3.4 Bering Sea Sea of Okhotsk Total Area -3.7 -58.7 -156.4 (sorry, I forgot how to align such tables on the blog) Here the drop is "only" 156k, CT exaggerates the area at lower latitudes. So the drop is mostly caused by Okhotsk, Hudson and the Bering/Kara/CAB section. I have uploaded in the forum what I call the delta map. Bright red and blue is where concentration crosses the 15% cut-off. Blueish where concentration increases by 7% or more, pinkish where concentration drops more than 7%. This should serve as a nice illustration. More information on the calculation is mentioned in the post just above that image.

The 174K drop then actually happened yesterday Tuesday, March 15th, but will then reported by CT on Thursday, March 17th, and CT will use the date of March 16th. for this drop. Almost. NSIDC reports concentration data of the day before. So yesterday that was 14th. NSIDC calculates extent and reports that as the 14th. CT does not report its Arctic area figures (based on this data) two days later (Thursday). The Southern Hemisphere area and Global area numbers follow one day after that (Friday).
