Aargh.....my eyes ...me eyes...should...not...have...read....article... A4R, reading articles like that do not give me hope for humanity...idiots...all
Toggle Commented Sep 16, 2012 on Joe Bastardi found a cherry at Arctic Sea Ice
Does it really matter ?. I think this inquiry can wait after the september refreeze commences...
good grief...
Did I already say that the resolution change is amazing!! Can't stop playing with the pictures....
The graphs have gone loco!! Only the CT area 2012 line has a similar curvature compared to previous years. SIE lines have been showing some wild inflections.

The Laptev bite is ominous looking....
Exercise 2. Keep pressing overlay/hidden to remove and reveal the overlay. Fascinating!!!

Exercise for the crowd. Go to http://www.ijis.iarc.uaf.edu/cgi-bin/seaice-monitor.cgi?lang=e and overlay Aug 22nd with Aug 23rd. There is a big open water hole right inside Windsat's NP hole.

Is it my idea, or AMSR2 data came on stream publicly, way faster than expected??
Wild!

One can clearly see the resolution difference!!

I saw it too, with firefox, when normally using chrome... And on top it says AMSR2 instead of Windsat... Chrome, just refreshed to AMSR2 too for 23 too. 22nd is still windsat. I guess they try to get ahead of events!! Wild ride this summer.

CICE ice thickness and drift charts show that a lot of MYI is about to board the Fram Express to oblivion
Using the double zoom feature of Arctic.io, one can see that snow is developing again in the Canadian Archipelago.
For 3D geometry, the surface area concentration of solid spheres packed in a box(a measure of available surface area) is given by a = 6*(void fraction)/d, where d is the diameter of the spheres and void fraction = volume spheres/(total volume). CAPIE is the void fraction equivalent for 2D geometry. For a given CAPIE there is an infinite number of (perimeter/area ratio,average floe diameter) pairs, each of them has a different "energy state", with higher total perimenter/lower floe size pairs having higher energy (i.e. taking more heat to generate). That is why the perimeter to area ratio, combined with CAPIE gives a unique state of the ice pack. Even if CAPIE remains constant in the next few years, a higher total perimenter of the SIA will denote a lower quality of the icepack.

Can any smarty pants here calculate the icepack perimeter? I suspect that it will be one of the metrics that can correlate with the melting rate and the ice quality or (icepack area)/(icepack extent) ratio. ImageJ might have the appropriate tools? Just a thought. Also I figured out that the fractal dimension of the icepack must increase the lower the quality and the higher the fracturing of the pack. Can be a simple metric?
CT Arctic Basin Area going to 2 M km2 ??
Damn you time zones..... Vacay at Greece and I cannot seem to enjoy my mornings without CT/DMI etc. updates. Another record is blown huh Al?
And let the compaction start!!
Has UNI Bremen hit a record already? At least the graph shows as much....Maybe I am crosseyed
John, You mean the famous "fat arse". This is partially true. You will probably have noticed that the beginning of the "fat arse" is earlier this year than others. There is a distinct probability that this the area will not go much lower than prior years. However, the ice cannot continue thining without showing in the area and extent metrics. Other people here (crandles, Chris "dosbat" Reynolds, Chris "torcher" Biscan) have noticed that and wondered when will the year be that the area/extent crashes. Maybe it is this year (and the storm has made sure that the probability goes up), maybe next year. Who knows. However, all metrics/statistics/empirical evidence, give a rather high probability that area will reduce lower than 2007/2011. The only thing we can do is watch, wait, and test our hypotheses against the real world. If we miss something that's good, we will learn something new. That's what the models do too, you put as much physics as you think is right, make a prediction, validate/invalidate, correct and go again at it. Healthy scientific approach...
Go to SLEEP!! :)
The last paper has a ton of information and time series for summer cyclone formation!! Happy reading.... Will keep me occupied...
