MASIE April 29 2014 – Arctic Ice Extent By Region As of Day 118

Published on April 29, 2014 by sunshinehours11 Comment

April 29 2014 MASIE Update (This Arctic Sea Ice dataset frm MASIE only has 28 days of data.

This is the gain/loss from day 91 to day 118. Negative = loss. Sorted with biggest loser in last 7 days at top. Northern Hemisphere is the grand total.

Notice that even though the NH shows a 404,000 melt in the last 14 days, only 16,782 melted in last 7 days.

The bottom 5 have all gained in last 7 days. Including 102,200 in the Barents Sea.

MASIE April 26 2014 – Arctic Ice Extent By Region As of Day 115

Published on April 26, 2014April 26, 2014 by sunshinehours12 Comments

This Arctic Sea Ice dataset frm MASIE only has 28 days of data. I leave out the NH total otherwise the all of the other lines would look kind of flat.

Earlier today I posted my sea ice update and noted that ice loss in the Arctic had been almost flat for a week (compared to last year).

MASIE totals are not identical to NSIDC totals. Its the trend that is worth looking at.

This is the gain/loss from day 88 to day 115. Negative = loss. Sorted with biggest loser in last 7 days at top. Northern_Hemisphere is the grand total.

Region	Start	End	Last 28 Days	Last 14	Last 7
Northern_Hemisphere	14,805,115	13,984,885	-820,230	-509,465	-121,570

Yellow_Sea	0	0	0	0	0
Barents_Sea	645,917	623,822	-22,096	-71,839	15,375

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.

The purple line near the top is the “Central Arctic “. You can barely notice it rose from 3221921 on day 88 to 3248013 on day 115.
