(Could you give me a reminder when you approach 100,000? Should be possible to reach this milestone hopefully before you have to extend the topic of this blog to Antarctic.)
Commented May 1, 2014 on Getting ready at Arctic Sea Ice
Getting ready
With the melting season getting ready to go full speed, I'm also busy getting everything ready. First of all on the virtual level by updating the Arctic Sea Ice Graphs page. I've slightly altered the daily graphs page, by adding a couple of links, graphs and category names to make it easier to ...
Did anyone notice that we can see the arctic again?. Webcams are back!

Perception of the Arctic
There was a time, not too long ago, when I didn't know the Arctic existed. Sure, I knew there was a North Pole and that it was cold there, but somehow I always thought that the Arctic and the Antarctic were the same thing, that someone had forgotten to add the Ant-. And of course, polar bears ...
I just (re) found a short animation of 20 years ice movement, compressed into 50 seconds. Illustrative about what is (was) normal movements. http://iabp.apl.washington.edu/animations/7998-05Xfast.mpg

The cracks of dawn
I was hesitating whether I should write about this (besides my personal combination of busy/lazy) for a couple of days, because the Arctic is such an amazing place that it's easy to get carried away. When you see something for the first time, it's tempting to go: "Oh my Gawd, that haz got to b...
Nice work Wipneus!. Also nice to see that the sum of Exponential fits for all grid cells results in a Gomperz fit for the total.
The location of the blue spot is also remarkable.(Is it?) Sceptics will continue for many years: "there is still ice on the North Pole".

PIOMAS January 2013
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: 2012 has ended the year with a total volume that's around 1000 km3 less than 2010 and 2011, but ther...
@Idunno: You need some humor to survive these times. Not knowing WUWT was typing their record-announcement when I was typing my comment. Their trick to use % to measure recovery is clever. This will give even higher records in the future. And after a few years when also winter extent has gone down significantly, this is probably the only way they can have a record.
But the bottom line is simple: You can only have a record refreeze after a record melt.

Record dominoes 12: CT SIA anomaly
The last record left this year has finally been broken (see them all on this page). Never since records began, has there been a larger anomaly from the 1979-2008 baseline in the Cryosphere Today sea ice area data set, as calculated by the Polar Research Group at the University of Illinois at Urb...
Well, if the CT global SIA anom record is out of reach (is it?) the last record (nr 13?) will be "the largest recovery". But this record is not something we will have to track. Others will do. ;-)

@Jim Petit. Your graphs are an excellent presentation of the scary numbers. I've seen your graphs many times before this year, but just today I discovered that you can still improve them. (Graph Annual volume maximum and annual volume loss; Wrong unit at the vertical axis? Volume in km^2???)

Why Arctic sea ice shouldn't leave anyone cold
The sea ice is leaving us a bit more every year. It's time to start contemplating its absence, which is why I teamed up with Kevin McKinney to write an extended version of the shorter piece you might see pop up here and there. Because you know, disappearing sea ice isn't without consequences. An...
CMIP5 suggests 60% of 1979-2011 rate of decline is externally forced. What does this mean? What is the other 40%?I tried to download the article but: paywall! Google found an other interesting document from Stroeve: www.cesm.ucar.edu/working_groups/Polar/presentations/2012/stroeve.pdf.

Sea Ice Cover
Below are research papers on Arctic sea ice cover, ranging from extent, area and concentration, to the effects on albedo. Click on the discussion page of a paper to read excerpts, download a copy and discuss the paper. If there are papers you'd like to see added here, you can comment at the end ...
Artful Dodger: 10 days not 10 September? Indeed wrong. I will have to wait a few days more. (Hoping the ice will not melt faster.) The previous record (excluding 2012) was 41% relative loss, around 23(?) August 2007. Present value is 48%.

Record dominoes 3: Cryosphere Today SIA
There are several scientific organisations that keep an eye on the Arctic sea ice cover and put out graphs to inform us of the amount of ice that is left. You can see most, if not all, of them on the ASI Graphs webpage. I expect the record on most of these graphs to be broken in weeks to come. -...
Just assume the anomaly stays at -2.36 for the comming 10 days. The normal amount for 10 September is 4.72. The remaining ice will be 2.36, That is 50% of 'normal'. Is this another nice (No, not nice) milestone?

Webcam 2 is alive again. Wet images. Based on the black/white markers on the reference poles a lot of melt took place last day's. Does anybody know the blak/white/black distances?

Webcam art
Every now and again the North Pole webcams produce beautiful images (like last year). This one is a bit artsy: When will the first puddles show up, I wonder?
Did our Polar Bear destroy webcam2? (no update of images last 48 hrs...)

Wel done, this seperate page with regionale graphs. Nice combination of CT annual graph with the monthly graphs from NSIDC. However from the values it is clear that they use different boundaries for the regions. Sometimes the area value is above extent, sometimes below...

SIE 2011 update 11: the heat is on
During the melting season I'm regularly writing updates on the current sea ice extent (SIE) as reported by IJIS (a joint effort of the International Arctic Research Center and the Japan Aerospace Exploration Agency) and compare it to the sea ice extents in the period 2005-2010. NSIDC has a good ...
..so it will be interesting to see what happens exactly.
If we see someting. The latest picture from webcam 1 is different from the one before.
