Do you know whether this camera 2 resides at the same location (Prudhoe Bay) or not? “Washington Edu” doesn't look very communicative about ..., albeit to me.

Talking about wind, a nice example of a combined wind-melt-evaporation action at Obuoy 12 - the pressure rifs still had raisor sharp edges merely a week ago.

Jim Hunt wrote: My suggestion for the "depressions" is wind blown snow But if so wouldn't one side be more deep as the other, snow even being piling up at the other side? Whereas apparently depth is equal and even around all of the buoys. Or if it was for the wind, the nearly perfect circles rather would have an oval shape. Aren't we blaming winds a little bit to much? For instance, if due to wind action the Mackenzie delta should be piled up with floes, whereas on the contrary a polinia already has been created. By the way, according to the respectable Webster the word 'depression' has many meanings, of which are “a depressed place or part : hollow” and “a pressing down : lowering”. And as we can't agree on the cause for now a general wording looks appropriate to me. Incidentally, Obuoy 9 already fell into it's own “depression”. :-)

A question from a very ignorant person: how to explain the depressions around the NPOE buoys?

Jim Hunt wrote: East Beaufort situation is due to wind rather than "considerable melt" Right, on condition high temperatures allow the wind to chop the ice into pieces. So probably the wind indeed has aggravated the situation but can't be seen as the cause. And as we all are aware of, mean temperature this winter in Alaska and NW Canada has been far above average. Another factor could be that high amounts of fresh water already are plunging into the Beaufort Sea. But that's just my guess for now ...

Look at that! The Helheim glacier is vanishing right before our eyes. At the first link you can navigate through images from September 2014 till 29th april 2015. Mind, some images are hidden behind others, so you have to click onto the tiny rectangles to the left and the right of the image in order to see it all [at least, at my system it's like that]. We know speed is at it highest in the middle of the glacier. So in theory in the middle the glacier should be longer than at the banks, creating something like a 'tongue'. But it is completely the other way around (do have a close look at the March 28th 2015 image]. IMHO meaning the glacier is already highly fragmented and collapsing under it's own speed. And remember, this has been the recession in Winter, and Summer has yet to come. Incedentally, looks like we are facing a combined 2007 and 2012 situation: extent is extremely low as in 2007, and there is already a considerable melt in the Mac Kenzie-Amundson street-East Beaufort Sea [as in 2012}.

Awaiting the journey to Ilulissat something to ponder about. As has been told already, the plots produced by the Danish DMI are describing masses of 4+ meters thick ice 300 km North of Wrangle Island and in almost the entire Beaufort Sea. As it is in the latest: DMI 9th of April plot. However, the Japanese ADS (Jaxa) plots are showing quite a different picture: ADS 9th of April plot UGH!? Except for the “standard” piles up North of the Canadian Archipelago, the entire Arctic looks to be covered with a mere 2 m thick ice, here and there with some surplus till 3m. We can't assume both have it right, can we? Anyway, beats me ...

While awaiting NSIDC's March overview-report we already can have a look at some of the NSIDC March statistics. As could have been expected, a new March 2015 mean minimum SIE record (minus 300.000 sq km in respect to March 2007). Into this record-minimum-extent the concentration is up 100.000 sq km compared to March 2007. And the concentration anomaly has risen to a staggering -1.000.000 sq km! Looks very much like the hope created by April 2010 won't come true ...

Cincinnatus wrote: And what part of "North of Wrangel" are you not understanding? Also Fairbanks is to the North of Wrangle Island, so you have to be more specific. But let"s have a look at the latest Denmark Ice thickness chart, the latest being 1 april 2015 What do we (hopefully you too) see there: 1. Directly around Wrange Island the ice should have 0,75 to 2,00 m of thickness. As it is every year. 2.In a 300 km large band to (what you probably call) the Nord the ice has 1,2 to 4,00 m of thickness. As it is has been each year in the past. 3.From there then almost the entire Beaufort Sea and a limited chunck of the central arctic should be covered with more as 4,00 m thick ice. A bit unusual, but is has been like that already in the past, and nevertheless the Beaufort-ice melted away in these circomstances. 4. And now the thing hard to believe. From The North-East coast of Greenland to Canada's Prince Patrick Island, the thick multi-years ice has gone away! Partly to the Beaufort Sea, partly to the Greenland Sea where is had been chopped to pieces by the Atlantic Februar-March storms. Making it possible the Arctic coast from Greenland to Prince Patrick Island would become free of ice. 5. Moreover, the ice in Neven's beloved Laptev-bit is thin, very thin (0,75 to 1,5 m). A thinness Stretching out to the pole itself. So it's likely the pole would become ice-free this year too. Anyway, taking in account point 2. to 5., we could reasonably assume an Arctic disastre is imminent. But perhaps you do have a private satellite turning around the Earth giving different data? If so, please, be so kind to share your data with us.

It's beginning to look like the polar bears have had the last word at point Barrow. Or would the ice be to thin to have anything installed on it? Anyway, the Barrow webcam is out of order since almost a month. And the "as soon as possible" there doesn't sound really convincing as we encounter the very same "ASAP" message at the Wales webcam which resides at the same website onto the same server. The "ASAP" there takes now more than one year and six months. I wrote a message to the Wales webcam responsable about a year ago, and received the answer the good guy was out for a trip around the world and other nice things. So it doesn't look good. To bad ...

People, The Arctic 1 Februari is updated now. Other than that SIE is as low as in the previous years since 2003, there seems nothing special nor any weirdness to report. But as we all sure know by now, even around the Arctic it isn't always as it looks like.

Boa05att told: Climate change brings colder winters to Europe and Asia Correction: Kate tries to sell us stories like that. To begin with, she puts as premise Winters in EurAsia were getting colder and colder hitherto. Which is completely false a statement. As far as I am concerned, this is outright nonsense. Looks to me more as a denier's trick.

Weirdness-lovers, To say again, you really are spoiled this Winter. On returning to Little Diomede while having a view to Ratmatof Island , we have to etablish the fact there is a fair amount of open water in the middle of the Bering Strait where both islands are situated. In the previous 12 December image we already could see ice formation was very under average. It is beginning to look like this Winter will be a very odd one ...

Ron Mignery stated: be a shut-down of the heat engine that drives NH weather Why? Arctic waters still would remain much colder as the tropical ones. Remember, there is no sun over the Arctic in winter. So there would be no reason at all the convection circuit should be interrupted. On the contrary, as an ice free Arctic would allow the Gulf stream waters to travel right into the pole more storms, much more bigger than the one from last August would be the consequence. We (should) know the American Army came up with that theory about 30 years ago, but that was just for cold war propaganda reasons. Thus we better put things like that aside. Of course, and as it is happening already, it could well be virtually the entire tundra region would dry out and turn into desert, but that is another matter, that phenomena is due to the vanishing permafrost.

Ron asked: Could the Arctic see tropical temperatures when the sea ice is gone? Actually, already now Summer temperatures of 30 °C are commun in Central Alaska and dito Siberia. And this feature seems to go further to the North every year. Moreover, Tiksi at the coast of the Artic Ocean has had in 1991 a "freakish" temperature as high as 34 °C. So, if there would be no ice anymore to moderate the temperature, Summer could be very hot even at the Arctic coasts in Juin-July. Hence the answer to your question is "Yes it could", but only for a short time.
