Ryder Glacier calving follow up:
The calving happened sometimes after July 10th
and the size is about 50 - 60 km2 or about ½ the size of the latest Petermann piece.
Comparing two MODIS images from 08/05/10 and 08/07/12 I can't see a signifcant calving event at Ryder Glacier. There are moving some pieces around. But at the front of the glacier is no really big chance visible.
Maybe I'm wrong...

Arctic storm part 3: detachment
Yes, ladies and gentlemen, the Arctic summer storm is still there. After approximately 48 hours (which is long for an Arctic summer storm) it has weakened some compared to yesterday or the day before, but as far as I can see sea level pressure in the centre of the storm is still around 970 mb, w...
Only comparing the shapes of the 2010 and 2012 CT SIA graphs, the graph of 2012 is very similiar to 2010, while the shape of the ice extent is quite more different ->

CT SIA: maximum reached (this time for real)
Update March 31st: It looks like the maximum has arrived even later. The peak from 11 days ago has been beaten by almost 8K square km. This isn't much, but those 11 days extra make it a super late maximum. And the Lord only knows if this is the final maximum. I'm not calling this one anymore, ev...

Summer 2011: Arctic sea ice near record lows
The summer sea ice melt season has ended in the Arctic. Arctic sea ice extent reached its low for the year, the second lowest in the satellite record, on September 9. The minimum extent was only slightly above 2007, the record low year, even though weather conditions this year were not as conducive to ice loss as in 2007. Both the Northwest Passage and the Northern Sea Route were open for a period during September...

September 2011 sea ice extent, looking ahead
The mean extent of Arctic sea ice for September 2011, calculated from the University of Bremen time series (website; technical paper), was 4.6 million km2. A Gompertz curve that I estimated last April based on Uni Bremen data for 1972 through 2010 gave a predicted September 2011 mean of ... 4.6 ...

Arctic sea ice near record lows
Arctic sea ice extent averaged for August 2011 reached the second lowest level for the month in the 1979 to 2011 satellite record. Both the Northwest Passage and the Northern Sea route appear to be open. Throughout August, sea ice extent tracked near the record lows of 2007, underscoring the continued decline in Arctic ice cover.

Open Thread 3
First off I'd like to inform you that I have finally managed to write a piece on my view of current economics. I didn't think it would fit here (as I believe this blog should remain about Arctic sea ice mostly), so I was lucky that Michael Tobis accepted it as a guest blog over at In It For t...

is it just me or has that crack in the Petermann Glacier extended quite a bit lately?

comparing last year at day 231 and this year at day 230 there is a little difference visible in the size and position of the crack:

Dramatic. Just looked up Ward Hunt on Google Earth. There was reporting of a widening crack.
On Modis there is a clear view of the Ward Hunt Iceshelf area now:

Hi Neven,
you're completely right, my post fits better to your other blog post, sorry for my confusion. And I understand your concerns about the english link, it's really better not to attract the wrong people. First I thought my browser has eaten the second link, but fortunately I read your post before I posted it again.
TOPAZ: a short interview

Hi everybody!
This is my first post here. I found an interesting news today about actual ice thickness measurements on the german site of Alfred Wegener Institute. They just completed their 6-week expedition over the Arctic with the Polar 5 research plane. At the moment the news is only in German, but normaly they translate it in english soon. I found some of the information in english on a site, that seems to be a denier site, but the information from the expedition in the first part of the arcticle there is better than no translation.
