May 10 2014 MASIE Update (Although the dataset from MASIE only has 28 days of data, I have started to save the data allowing the analysis to go further back)
This is the gain/loss up to day 129. Negative = loss. Sorted with biggest loser in last 7 days at top. Northern Hemisphere is the grand total.
A bit of an uptick over the last day for a net gain of 37,500 sq km with Baffin Bay Gulf of St. Lawrence being the largest gainer at 36,073.

May 8 2014 MASIE Update (Although the dataset from MASIE only has 28 days of data, I have started to save the data allowing the analysis to go further back)
This is the gain/loss from day 88to day 121. Negative = loss. Sorted with biggest loser in last 7 days at top. Northern Hemisphere is the grand total.
Today I added Last 1 day and Last 39 (which will change every time I post). Four of the regions actually gained ice over the last 39 days, but that is dwarfed by losses elsewhere.

Update: Since March 27 Antarctic Sea Ice Extent has been more than two standard deviations above normal. 82 days out of 126.

May 6 2014 MASIE Update (This Arctic Sea Ice dataset from MASIE only has 28 days of data.)
This is the gain/loss from day 94 to day 121. Negative = loss. Sorted with biggest loser in last 7 days at top. Northern Hemisphere is the grand total.
Normally I only show Last 28,14 and 7. Today I added Last 3 days because it was so interesting.
In the last 3 days Northern Hemisphere actually rose 2,503 sq km because Barents Sea rose 34,216 sq km.
Hudson Bay, Baltic and Chukchi Sea also rose. This rise hasn’t shown up on the NOAA dataset.

May 3 2014 MASIE Update (This Arctic Sea Ice dataset from MASIE only has 28 days of data.)
This is the gain/loss from day 94 to day 121. Negative = loss. Sorted with biggest loser in last 7 days at top. Northern Hemisphere is the grand total.
The bottom 3 have all gained in last 7 days. Including 44,747 in the Barents Sea.
I assume the Chukchi Sea and Hudson Bay only started melting in last few days since the 7 day melt is the same as the 28 day melt.
The melt has resumed in the last 7 days after a small pause in previous 7.

Here is the MASIE graph. The flat lines at the bottom are regions that have melted and are now ice free. The completely flat lines elsewhere indicate no melting at all yet. The changing lines indicate melting regions.

Big story:
“There is a huge event being forecasted this year by the CFSV2, and I don’t know if anyone else is mentioning this. For the first time in over a decade, the Arctic sea ice anomaly in the summer is forecast to be near or above normal.”
