From EarthSky:
NASA created a video showing the decline of the ice from its near-maximum state (in early spring 2011) to the near-minimum state (in September 2011) using the AMSR-E instrument on NASA’s Aqua satellite.

Neven, I am rather surprised at the huge relatively large daily increases in SIE. As most people I expected the minimum to come later, and with relatively small numerical daily changes. Are the last few days unusual?

Ice extent down by 34,531 sq km in the past 2 days. The plot thickens. Or thins?

I like the arctic sea ice animation but the rotation NASA put in it is distracting. I think it would be better if NASA just did a straight view from above the North Pole. With no rotation. Just focus on the state and extent of the ice.

I rescind my earlier question.
I have a new prediction though. The number of hits on IJIS, NSDIC DMI and Cryosphere today websites will drop off precipitously.

Wonderful animation.
Can you also post a video of the 2010-2011 freezing-season or should we just watch this video in reverse?
Posted by: Hans Verbeek | September 19, 2011 at 21:33
Watch it in reverse, Hans. ;-)
Just kidding. Arctic.io made a nice animation of the last freezing season, using radar images.

Tony Duncan. Sorry for the late answer. Those days of 'refreezing' weren't particularly unusual. Weather circumstances were causing all of the openings between the weak ice in the East Siberian Sea to fill up. Similar to last year The Arm was saved just in time.
Daily page views of this here blog has dropped about 75% since the minimum was called. :-)

Hi folks,
Radar images of sea ice (like the animation by arctic.io above) are very useful during the long Arctic night, and freely available if you know where to get them!
To access Advanced Scatterometer (ASCAT) radar images, do the following:
http://manati.orbit.nesdis.noaa.gov/datasets/ASCATData.php
BONUS Tip:
You can go directly to images from 2010 by manually adjusting the URL in the following link (example, where 2010 is the year and 001 is the day-of-year wanted, Jan 1):
http://manati.orbit.nesdis.noaa.gov/ascat_images/ice_image/msfa-NHe-a-2010001.sir.gif
Further Reading:
The Advanced Scatterometer (ASCAT) satellite was launched in 2007 by the ESA. Read all about this technology here:

Cheers!

I realize that this is a bit off topic. And not only that, but I'm guessing that only people who are eligible to vote in the United States can help me. But I'm going to ask for your help anyway....
I just found out about a new petition site on whitehouse.gov
Anyone can submit a petition, and if it gets 5,000 signatures within 30 days, someone will review it.
I just posted one, and I'd be grateful if you'd be interested in signing it. You can read all about it at:
https://wwws.whitehouse.gov/petitions/!/petition/tax-polluters-and-other-people-who-benefit-expense-common-good/S7BztR3v
(You'd need to register in order to sign it, but you can read about it without doing so.)
Feel free to pass this on,
bill
p.s. You can create a petition for your favorite issue, too!
Posted by: Bfraser | September 24, 2011 at 01:35
Bill, post your petition in a comment on Climate Progress, and send Joe Romm an email asking him to promote it. He may even write a blog post for you (as may Neven).
Cheers,
Lodger

Should such a petition be created regarding protection of academic freedom in light of the Charles Monnett?
My reaction to the affair is to also call for an inquiry into whether the starting of the inquiry amounts to some form of an abuse of power.
I will wait for comments before considering the drafting of such a petition.
Posted by: crandles | September 24, 2011 at 11:25
Bill, I mentioned your petition towards the end of the latest and last SIE update.
