CT SIE maps are beginning to look like someone started punching random numbers into a fractal generator. Has anyone else noticed the anomaly that keeps showing up between the North Pole and Franz Josef Land? I've noticed it off and on for several weeks - it must be an equipment malfunction. I've circled the crescent shaped anomaly

Zooming in on the MODIS images of the East Siberian Sea coast, there are some spectacular images that must be algal blooms. I'm usually more interested in the condition of the ice, but there's less and less of it to look at :)

Algal Blooms in the East Siberian Sea

Thinks are not looking to good. A lot of the posters on Americanwx Climate change forum think we will be even with 2010 now because of the recent slow down.

I am not an expert but I would be stunned if we only drop another 2 mil km2 on the extent. The Sea Ice Area is at all time lows for this time of year. Well over a million km2 of ice is already losing concentration rapidly.

I am going with 4.3 mil km2 maybe more maybe less


Nice work Neven - it will be interesting to watch this develop over the next six weeks. One thing thats not obvious in the animation is that the channels off the image to the lower left (around Bathurst and Devon Islands) are much clearer than last year, which should allow quick advection as the break-up progresses (although I agree that 2010 is ahead at the moment).

You did a fine job last year on the "Pole Hole". I'm thinking you will probably want to watch that area closely too (not trying to set you homework though). From what I can tell through the cloud, it looks like the Laptev/Siberian side is going all cheesy again...

Anything above 2007's extent and the deniosphere will be saying the Arctic is recovering.
Anything below 2007's extent and the story will be it is all part of a natural cycle and there is still lots of sea ice in the Antarctic.
Either way the end result will be: politicians and others will still do next to nothing.

Typed the word 'passage' in the search box to see if anyone had mentioned the full-open of the main (NW) passage through the CA, but CT and Bremen maps suggests it is now truly wide open, bar the slivers floating around.



I just thought the same thing a minute ago when looking at the Uni Bremen sea ice concentration map. Funny that this hardly news anymore, eh? Fourth year in a row now for both passages being open?

I'll do a short post on this in a day or two. If I can be bothered. ;-)

Really annoying BTW that things have been cloudy for so long now. I'd really love to have a clear view of the CA for a couple of days in a row.

There hasn't been too much about the NWP so far, but Matt Ryan, the "solo the Americas" guy, cleared it with no problems. He's about halfway to Point Barrow, AK, if I'm reading his GoogleMap position (and remembering where Point Barrow is) correctly.

The NWP opened up a couple of days ago during the 'Great Excitement'. Attention went to the areas where ice made more dramatic changes.


Coincidentally today a good satellite image of Sverdrup and Peary channels. If it weren't for the winds, I'm sure there'd be major ice transport through the channels of the Queen Elizabeth Islands.
