Antarctic Sea Ice Extent July 31 2014 – 1,110,000 sq km Above Normal – 133rd Daily Record

Published on by sunshinehours1Leave a comment

Antarctic Sea Ice Extent is 1,110,000 sq km above the 1981-2010 mean. That is the 133rd daily record for the year.

An interesting note: Both 2013 (black line) and 2012 (orange line) set all time maximum records … yet were 900,000 sq km apart at this day.

Published on by sunshinehours1Leave a comment

Antarctic Sea Ice Extent is 1,107,000 sq km above the 1981-2010 mean.

After dropping 90,000 sq km two days ago, ice extent rose 100,000 sq km the next day.

131 daily records in 2014. And 209 out of 209 in the top 5.

Sea Ice Data is late today – July 29 2014

Published on by sunshinehours1Leave a comment

Update: Arctic/Antarctic have appeared. MASIE is still one day old.

Normally the NSIDC Sea Ice Data is posted on their site at 6:51am Pacific Time.

Some days it is late or isn’t updated until the next day.

The MASIE data gets updated about 7:17am Pacific. It was updated … but it the previous days data.

 

MASIE Arctic July 28 2014 – Freezing and More Ice

Published on by sunshinehours11 Comment

July 28 2014  MASIE Update

The top graph just shows the Central Arctic … and shows 4 days in a row of freezing. The Central Arctic has 3.2 million sq km out of 7.8 million sq km left for the whole Northern Hemisphere.

The 2nd graph shows 2 days of freezing for the whole Northern Hemisphere … about 30,000 sq km net total freezing. (When I use the term freezing I mean more ice. It could be wind moving the ice around too)

The graphs have different scales.
