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

Published on 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

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.
