MASIE May 31 2014 – Arctic Ice Extent By Region As of Day 150
May 31 2014 MASIE Update
This is the gain/loss up to day 150. Negative = loss. Sorted with biggest loser in last 7 days at top. Northern Hemisphere is the grand total.
While melting resumed in many regions over the last one day, over the last 3 days daily melt was only -9,229 sq km per day.
The Greenland Sea continues to climb.

This is the gain/loss up to day 144. Negative = loss. Sorted with biggest loser in last 7 days at top. Northern Hemisphere is the grand total.
I’ve added a “NH (Average Loss per Day)” line to the bottom of the table. The interesting figure is that even though a lot of ice melted over the last 1 day, very little melted over the last 3 days: -7,232/day
