HI Patrick good to hear from you!
re:Petermann Gletscher
I realized how unpleasant science could be!
Sabbatical (I hope)
I've alluded to it a couple of times already, but I'm really going to take a break from blogging, as I have been struggling with an Arctic burn-out since 2012. On the one hand it's caused by everything that has been and still is going on in the Arctic. The learning curve, the excitement, but mo...
Hi Neven,
I remember the days when we were in the class room, following PatrickLogicman, I will thank both you and Patrick for what it resulted in:

And by the way the ESA story was without the name of the Author, now you know why!
Jakobshavn record retreat
What a coincidence. Yesterday I wrote in a comment: There's a fantastic segment on the Arctic Sea Ice Forum for discussing Greenland and its glaciers, with people presenting all kinds of analysis and satellite images. Really top quality stuff. Well, the folks there (forum member Espen Olsen to...
ESA managed to hi-jack the calving story, I guess the main reason for doing that was that the original story released in Arctic Sea Ice Forum
https://forum.arctic-sea-ice.net/index.php/topic,154.msg60933.html#msg60933
was based on USGS material and NASA, that was not a pretty ESA thing to do!!!

But I am surprised one of the biggest or rather most important tourist- and natural sites in the Kingdom of Denmark, was not mentioned to my knowledge in any danish media, but then other the other hand I am not that impressed with them anyways!

Neven thanks for showing this event so quickly and thanks to A-Team for the additional documentation.
I am convinced this is largest single calving event that ever happened at Jakobshavn since the glacier went dual (southern and northern branch).
My present estimate is Jakobshavn lost somewhere between 11 and 12,5 km2 from August 14 to August 15 2015.

ASI 2015 update 3: what's it going to be?
During the melting season I'm writing (bi-)weekly updates on the current situation with regards to Arctic sea ice (ASI). Central to these updates are the daily Cryosphere Today sea ice area (SIA) and IJIS sea ice extent (SIE) numbers, which I compare to data from the 2005-2014 period (NSIDC has...
We just had a seasonal around the 1st of June calving at Jakobshavn:

Very interesting: Just have one question for the
"No slowing down of Jakobshavn Isbræ in 2014: Results from
feature-tracking five Greenland outlet glaciers using Landsat-8 data and
the ImGRAFT toolbox"
presentation?
Why is there no mention about Zachariae Isstrøm? (more important than most of the other glaciers observed, at least compared to 79?)
EGU 2015, my first scientific conference
I've been living in Austria for 5 years now, living a mere 2 hour drive from Vienna, but somehow I've never come around to visiting the European Geophysical Union's annual general assembly. This year I've decided to make that drive to the Austria Center Vienna and attend EGU 2015, a decision m...
How about a trip to Jakobshavn Isbræ?

PIOMAS April 2015
Another month has passed and so here is the updated Arctic sea ice volume graph as calculated by the Pan-Arctic Ice Ocean Modeling and Assimilation System (PIOMAS) at the Polar Science Center: After the levelling off in volume gain we saw during February (see previous PIOMAS update), the 2015 ...
Neven,
I am surprised you wouldnt call it a max yet?
(I know I am in deep water now, but luckily I am a reasonable swimmer)
Mad max?
Okay, I'm not calling the max - short for maximum extent of the sea ice pack that marks the end of the freezing season - as I've sworn not to do that anymore since 2012, when I called the max twice, only to see the trend line bounce up higher and later. But this year something really interestin...

"It’s no surprise that Arctic sea ice is thinning."
And IJIS is already in a melt mood with record lows:

Erase and rewind
I don't know what the most interesting forum thread on the planet was last week, but this week it's definitely the Nares Strait thread, over on the Arctic Sea Ice Forum. All who regularly follow Arctic events, know that one of the coolest places in it is Nares Strait, the waterway between Elles...
John,

Yes Christoffer, we are handling km2 like bankers are handling billions.

Steensby Gletscher, North Greenland.
A sizeable (~32 km2)calving happened a few days ago, and is about 50% larger than the calving in 2012, this only the 2nd calving ever reported.

I migth be irrational, but where I live Scandianavia, of course ice do thin during the spring, but in the end of that process it suddenly disappear overnite, in most cases. And since we watch sea ice from above (from satellites)it will look the same way!
Poof, it's gone
One of the reasons for setting up the Arctic Sea Ice Forum, was to increase interaction and make more space for visual gems that do not fit the narrow comment section of this blog (check out for instance the Jakobshavn glacier thread). One of those gems was posted yesterday by commenter epiphyt...
It is not that I want to repeat myself, but I always believed the sea ice will disappear overnight, in the same way lake and river ice behaves.
So what Epiphyte discovered I totally agree upon, despite what other say about slush, in this phase it behaves like slush, no matter the size of it.
