The video below (made from US Navy data) shows that most of the Arctic is now covered with ice more than 2.5 metres thick.

Compare with the much thinner ice in 2008

NOOOO!!!!!!!! It’s in a death spiral I tell you!!!!!!
PIPS 2.0 is quite simply wrong. It’s wrong in pretty much every respect I can independently check.
* The PIPS map shows ice > 1 metre thick surrounding the entire northern half of Novaya Zemlya. When you look at the satellite data (AMSR-E or MODIS), it’s open water.
* The PIPS map shows Hudson Bay and Baffin Bay as thicker in 2011 than in 2008. I focus on these because there’s exceptionally good, detailed observational data for these regions from the Canadian Ice Service. In all respects, PIPS is wrong.

If the PIPS charts accurately matched reality, there would not be a single blue pixel in Hudson Bay or Baffin Bay, and no cyan pixels in the Canadian Archipelago.
I think you have it backwards.
NSIDC shows more ice around Novaya Zemlya than PIPS

WOW!
Measuring the color in Pixels!!!! Next thing you know someone will claim this shows some meaningful condition that is changing in the region based on enhanced resolutions over the period of observations which invalidates any claims of reliable results!
Measuring color in pixels also results in an up to 85% error margin. That is some sort of record for accuracy! It probably beats Mann’s methods!
Eh, look at the actual concentration data, not just a low-resolution extent graph.
Here’s the latest AMSR-E pic
http://arctic.atmos.uiuc.edu/cryosphere/NEWIMAGES/arctic.seaice.color.000.png
As you can see, the ice to the north of the island is low concentration (0-40%) with large areas of open water. This can be confirmed visually via the MODIS images here.

The northern half of Novaya Zemlya is at the bottom left of the image. According to PIPS, that entire corner should be a 1m thick sheet of ice: instead, there are large areas of dark open water almost as far as the tip of the island. Around the tip itself, there is some ice with extensive cracking – however it shows as grey rather than white, indicating that this is very thin and the water is showing through it.
NSIDC shows the whole area as being “ice” in its extent chart (which you linked), firstly because of the 15% threshold to be counted in ice extent, and secondly because they use the SSM/I sensor which is slightly more sensitive to very thin ice. The latter factor is one reason why the NSIDC figures for extent always track slightly above the IJIS figures.
The PIPS model (note: not data) has the entire area as 70% concentration of 1-metre thick ice. It is wrong.
“PIPS 2.0 is quite simply wrong. It’s wrong in pretty much every respect I can independently check.”
And then you reference one source. Uhmm……..
My
datapicture beats up your picture? You should probably explain why you believe EC carries more validity than PIPS.PIPS is a model, the Canadian Ice Service is direct observation.
You would think that the Navy would get it together after all these years.
What do they know, it isn’t like they’re really in the area or anything………..
One of those frozen pixels is probably the Catlin 2011 expedition . . you can almost hear them complaining about how cold it is while they blame their lack of progress on excessive ice and cold caused by Global Warming.
Actually, not only is the ice growing compared to 2008, but the thickness is increasing. Take a look at March 1981 vs March 2011: http://stevengoddard.files.wordpress.com/2011/03/screenhunter_03-mar-06-15-12.gif?w=640&h=317 and you can see that the purple is deeper, indicating more thickness. Also of note is the terrain that is simply covered in snow, whereas it was nearly snow free decades ago. IF global frauding was real, the pictures would be in the opposite chronological order. Seems a tad odd that the Cryosphere pictures for the same date would look so different, too, considering this one shows the entirety of the area.
I think the Modis sat pics show exactly what the Pips data has for Novaya Zemlya.
If anything there is more ice as of today.
Also noting we are now in the period were the sea ice reaches a maximum on average. But going by the current temperatures around the Arctic, there is a lot of freeze to come yet.
