The latest IJIS value : 5,113,594 km2 (October 13, 2012) An increase of around 116k, ever so close to touching the 2007 line now

That's more like it seems to of filled a bit and spread south, just needs to spread further west now. www.natice.noaa.gov/ims/

Ice quite a bit closer to the coast now let's get some mile wide ice machines up there to help it on Lol! Apologies for double post i was meant to put them both in one

Cheers for that Amazing to think Barrow isn't a vast amount further north than the top of scotland

That chart shows extent near 6 million and above 2007? something they know that the others dont?

Quite stormy up there at the moment then Do you know off hand when on average barrow's coasts are ice bound from?

Let's hope the low doesn't disrupt it too much as another big set back could be disastrous? Like always only time will tell Let's hope the low doesn't cause too much damage.

Hi Yido I've seen it show a faint outline around the uk as well, and we don't have sea ice round us ever some kind of glitch? makes you wonder how accurate some of the other pixels are.SST'S in that area are currently in the low teens at moment so way to warm for ice yet You can see misreported ice on the latest update as well.

More gains like that please The IJIS latest value : 4,868,438 km2 (October 11, 2012) Looks like were keeping the strong daily 100k+ gains up Long may it continue around a 115K gain? The angle of the line is very encouraging at the moment IMO

Barrow Sea Ice Webcam Barrow looking much icier and snowier now as well Is that ice forming on the coast? or strong waves

Much roomier now we can just stick to the ice increase now and not get way laid Current northern hemisphere sea ice anom like BFTV says it should be called cryosphere 2 days ago though So the there might be a higher or lower anom by today. http://arctic.atmos....edu/cryosphere/ -2.555 million on the anomaly front

Found this, i think it's about an eruption in 2009 that enveloped the whole arctic region with sulphates any link to the poor performance in ice this year? do you think? Properties of Sarychev sulphate aerosols over the Arctic JOURNAL OF GEOPHYSICAL RESEARCH, VOL. 117, D04203, 21 PP., 2012 doi:10.1029/2011JD016838 http://www.agu.org/p...016838.shtml Points Stratospheric summer aerosols over the Arctic had effective radius ~0.28 um Stratospheric summertime AODs at 500 nm were between 0.03 and 0.05 The e-folding times of stratospheric aerosols were ~4 months Aerosols from the Sarychev Peak volcano entered the Arctic region less than a week after the strongest SO2 eruption on June 15 and 16, 2009 and had, by the first week in July, spread out over the entire Arctic region. These predominantly stratospheric aerosols were determined to be sub-micron in size and inferred to be composed of sulphates produced from the condensation of SO2 gases emitted during the eruption. Average (500 nm) Sarychev-induced stratospheric optical depths (SOD) over the Polar Environmental Atmospheric Research Laboratory (PEARL) at Eureka (Nunavut, Canada) were found to be between 0.03 and 0.05 during the months of July and August, 2009. This estimate, derived from sunphotometry and integrated lidar backscatter profiles was consistent with averages derived from lidar estimates over Ny-Ålesund (Spitsbergen). The Sarychev SOD e-folding time at Eureka, deduced from lidar profiles, was found to be approximately 4 months relative to a regression start date of July 27. These profiles initially revealed the presence of multiple Sarychev plumes between the tropopause and about 17 km altitude. After about two months, the complex vertical plume structures had collapsed into fewer, more homogeneous plumes located near the tropopause. It was found that the noisy character of daytime backscatter returns induced an artifactual minimum in the temporal, pan-Arctic, CALIOP SOD response to Sarychev sulphates. A depolarization ratio discrimination criterion was used to separate the CALIOP stratospheric layer class into a low depolarization subclass which was more representative of Sarychev sulphates. Post-SAT (post Sarychev Arrival Time) retrievals of the fine mode effective radius (reff,f) and the logarithmic standard deviation for two Eureka sites and Thule (Greenland) were all close to 0.25 μm and 1.6 respectively. The stratospheric analogue to the columnar reff,f average was estimated to be reff,f(+) = 0.29 μm for Eureka data. Stratospheric, Raman lidar retrievals at Ny-Ålesund, yielded a post-SAT average of reff,f(+) = 0.27 μm. These results are ∼50% larger than the background stratospheric-aerosol value. They are also about a factor of two larger than modeling values used in recent publications or about a factor of five larger in terms of (per particle) backscatter cross section. N. T.

Around an 89k gain this time?. The latest IJIS value : 4,752,656 km2 (October 10, 2012)

Blimey Just when i thought there was enough going on to mess things up, we have the chinese revolution of development coming into play I'm kind of hoping the speed of technology advances in places like china and japan etc might see some solutions in the future, to the arctic and wider global problem, but as ever we'll have to wait and see. We seriously need to get some halt on the chopping down of c02 drinking trees in our rainforests and more locally, as our global forests do provide an answer of sorts they are the "lungs" of the planet afterall , and the main regulator of our climate system. More trees, less c02 in the air= less co2 to make unatural warming? that is if c02 is the only factor .

Take each day as it comes in other words,which is a fair statement to be honest. Bit like a game of snakes and ladders the ladder part is ice extent climbing to ever higher extents in certain areas (winter) but the snake in the equation is the strength and thickness of the ice, which come the next melt season is thinner and more likely to melt out. Also as you say if the water trapped is still abnormally warm underneath at winters end it has a head start and we end up in a catch 22 cycle?. I would like to be pleasantly surprised at the end of this freeze season which is always my motivation, but that doesn't mean i'm blind to the fact it may be even more dismal either next year unfortunately. Meanwhile i feel like were wishing our lives away at the moment and hope that it may settle down again in the next decade, so that we can just enjoy our lives and seasons again My hopes may realistically be dashed, or i might be pleasantly surprised, but for the sake of the human race, we need to get some re-balance up there, this might not happen anytime soon admittedly but we all need hope, and i think this is why some people are holding on to each and every increase that appears above the norm as far as extent increases go but maybe overlooking the thickness issue at the same time

That was fine thanks especially at that time in the morning I suppose to get a more rounded idea of a situation it is best to use many sources and then you have all bases covered

Does that mean the IJIS sensor can see ice, which is thinner than the NSIDC one can so it reports more extent, all be it a certain percentage thinner? would it not be easier just to stick with IJIS'S Amsr2 sensor as it sees more? or is it not as straight forward as that? Thanks in advance. Think i'm asking too many questions at nearly bed time.

So we need 5 or 6 days well over 100k to break even with 2007? why are we getting two different increase sizes between IJIS and NSIDC? is one slightly behind the other?

Hi IBringTheHammer I reckon so too, a little bit of moving the ice around on the 2007 map and were actually not far behind at all now? Still bad that we were behind at all but all we can do is wait and see if we can keep up our 100 thousand odd increases up Here is last years concentration and extent, were quite a bit behind 2011still.

http://www.ijis.iarc...ice-monitor.cgi AMSR2 Sea ice concentration map from IJIS 10/10/12 nice to see the ice forming around the siberian coasts now Compared to the same day in 2007, notice the different ice distribution between the years.Open sea is slightly closer to the pole in 2007 even though there is more ice in other areas compared to today.

Seems to be a few more people like myself being braver and posting this ice season Good to be able to get everybody's input. And it keeps the more knowledgeable posters like BFTV,Gray Wolf and many others etc busy trying to answer our questions Would be interesting to hear from Carinthian in this thread, as I seem to remember he used to host the ice threads?

The latest IJIS value : 4,574,688 km2 (October 8, 2012) Forgive if already posted but another good gain of another 100 thousand odd? let's hope it keeps it up.

World temps according to The weather channel as of 21:00pm today Nice cold pool starting over siberia? good for ice and spread of snow in that area Alaska and northern Canada looking mild with a still very snowless Barrow in Alaska currently a balmy +2.Need to rename to the Barrow Sea ice-less webcam Barrow Sea Ice Webcam

Edit: posted in wrong thread

IJIS value : 4,173,594 km2 (as of October 3, 2012) The latest value : 4,256,875 km2 (October 5, 2012) 80 odd thousand more than the 3rd, slightly disappointing over two days still.
