Antarctic Sea Ice Update February 18 2014 – 697,000 sq km Above The Mean – Day 48

Published on by sunshinehours1Leave a comment

Antarctic Sea Ice Extent is 697,000 sq km above the 1981-2010 mean. Which is 23.9% above the mean. (Lots of people hate me using the term “normal”).

The mean for day 48 is 2.91 million sq km. Sea Ice Extent for day 48 is 3.61 million sq km.

From day 47 to day 48 extent fell by 27,000 sq km. From day 46 to 47 extent actually rose by 64,000 sq km (I mistakenly said 38,000 yesterday).

So day 46 could turn out to be the day of the minimum Antarctic Sea Ice Extent for 2014. But it could still fall below that. No predictions from me.

Sea Ice Update February 17 2014 – Antarctic Sea Ice Extent Still 25% above normal

Published on by sunshinehours186 Comments

A quick update for sea ice extent:

  • Global Sea Ice is 93,000 sq km below the 1981-2010 mean.  That is 0.5% below “normal”
  • Antarctic Sea Ice is  706,000 sq km above the 1981-2010 mean. That is 25% above “normal”.  Antarctic Sea Ice Extent actually rose 38,000 sq km from day 46 to day 47. Minimum could be near.
  • Arctic Sea Ice is 799,000 sq km below the 1981-2010 mean.  That is 5.25% below “normal”.

Antarctic Sea Ice Extent pdate February 14 2014 – 23.4% Above Normal

Published on by sunshinehours1Leave a comment

Antarctic Sea Ice Extent only dropped 5960 sq km from day 43 to day 44. Which brings it to within 9310 sq km of the 2008 record for highest minimum. That means at least one more day with the chance of a new record occurring. Maybe two. It isn’t impossible for this to be minimum, just unlikely. The earliest minimum was day 43 in 1996.

Antarctic Sea Ice Extent is still 702,000 sq km above the 1981-2010 mean, which is 23.4% above the mean.

Antarctic Sea Ice – 24% and 738,000 sq km Above Normal – Day 42

Published on by sunshinehours1Leave a comment

A week ago I was sure a new record would be set for highest minimum. Two days ago I was sure the record would not be set. Now I’m not predicting.

Antarctic Sea Ice Extent is 738,000 sq km above the 1981-2010 mean. Which is 24% above. The anomaly was slightly higher today because of the minimal melt – 30,000 sq km.

Extent is 3.805 million sq km, and is still 110,000 sq km above the record highest minimum set in 2008.

I’ve added the 2008 Highest Minimum point to this graph. Data is here. Click for bigger.

Antarctic Sea Ice – 717,000 sq km Above Normal – Day 41

Published on by sunshinehours11 Comment

Antarctic Sea Ice Extent is 717,000 sq km above the 1981-2010 mean. Which is 23% above. Today was the first non-record day in 18 days.

Extent is 3.83 million sq km, and is still 140,000 sq km above the record highest minimum set in 2008.

I’ve added the 2008 Highest Minimum point to this graph. (But it isn’t looking as good for a new record now). Data is here. Click for bigger.

Antarctic Sea Ice – 22nd Daily Record of 2014 – 18th In A Row – Day 39

Published on by sunshinehours1Leave a comment

The 22nd daily record for Antarctic Sea Ice Extent in 2014 was set yesterday on Feb 8  (Day 39). The old record was from 2008.

The old record was broken by 78,260 sq km. Sea Ice is 807,000 sq km above the 1981-2010 mean.

Antarctic Sea Ice Extent is 27.4% above normal as of Feb 7 2014

Published on by sunshinehours16 Comments

Antarctic Sea Ice Extent  is really on track to have the highest minimum in the modern satellite era.

Antarctic Sea Ice Extent as of Feb 7 2014 was 904,000 sq km above the 1981-2010 mean and 220,000 sq km above 2008.

904,000 sq km above normal is 27.4%. Day 37 was the 20th daily record of the year.

Antarctic Sea Ice – 29% Above Normal – 17th Daily Record of 2014 – 13th In A Row – Day 34

Published on by sunshinehours12 Comments

The 17th daily record for Antarctic Sea Ice Extent in 2014 was set yesterday on Feb 3 (Day 34).

The old record was broken by 290,000 sq km. Sea Ice is 980,000 sq km above the 1981-2010 mean. Thats 28.65%.

And WOW …. I know this is probably just an aberration (but it isn’t a normal time so who knows) but extent only fell 3230 sq km from day 33 to 34. Normally at this time of year extent falls around 40,000-100,000 sq km per day.

Caveat: the raw data has 0.00058 sq km in the missing column (which is usually 0). Not sure what that means, but that is only 580 sq km.

Antarctic Sea Ice – 16th Daily Record of 2014 – 12th In A Row – Day 33

Published on by sunshinehours13 Comments

The 16th daily record for Antarctic Sea Ice Extent in 2014 was set yesterday on Feb 2 (Day 33). For the first time this year the old record was from 2012, not 2008. 2012 did not have a high minimum, but did go on to set a new all time record at maximum (which was broken in 2013).

The old record was broken by 240,000 sq km. Sea Ice is 904,000 sq km above the 1981-2010 mean. Thats 25.76% above the 1981-2010 mean.
