Marginally off topic too, but to whom it may concern: About a week ago the so called ZeppelinCam vanished into the High Nirwana. Called 'ZeppelinCam' because it had been installed on a mount called 'Zeppelin' at Svalbard's island Ny-Ålesund. Albeit cunningly being hided it is fortunately still available at the following address: ftp://ftp.npolar.no/In/ZeppelinWebCam/web/zeppelin_12.jpg Bottom line, 'current.jpg' has been renamed to 'zeppelin_12.jpg' onto a different address. By the way, another cam nearby is available at the following address: http://velferden.moimnorden.de/_media/wiki/user/kb_webcam/airport.jpg So, the 'zeppelinCam' resides high in the mountain on the right of the previous image [airport.jpg].
We have had already some suspicion, but now it's clear, a first melt pond visible at the washington.edu cam 1. Do look to the middle right. At the washington.edu cam 2, to the right too, the “depression” the buoy is in is half filled with water.
Literal an example of what the Dutchman use to call Noorderzon (= midnight sun). Enjoy and/or download.

That shelf jutted about 50 m out above sea level, thus had a thickness of about 400 m [of which about 350 under sea level]. So a few dozen meters deep melt ponds never wouldn't have drained anything there. Remember, Larsen B split into pieces in about 24 h time, but that had nothing to do at all with melt ponds. Other than that you have it right, indeed melt ponds on Arctic floes never go deep, as they survive only for a week, max two, as it has been seen each year hitherto.
Confirmation,today, for the 19th of Juin ADS-NIPR states only a minus of 14 square km in extent, in respect to the 18th. Whereas UNI-Bremen shows a massive drop in concentration. Me thinks it's a phenomena we haven't seen hitherto ...

Navigante wrote: sensationalist way. To put it mildly. I rather would say it's misleading as the published Cryosphere (not Cyrosphere!) chart shows SIE, not Sea Ice Concentration what the 340.000 Square kilometer are about - so it has nothing to do with Neven's ''centuries''. And that it solely is about concentration can easely be monitered at the UNI-Bremen maps from yesterday and the days before. Bottom line, we can miss that kind of input as much as Cincinattus' contributions. Incidentally, yesterday ADS-NIPR showed a drop of only 20 square km in extent.

Meanwhile, what we do know are the differences between each year from 2003 on. Do have a look at the 1st Juin parade. BTW, it looks to me as if our friend Cincinattus made his re-appearance. Nothing wrong with that, Gods and Divinities reveal in many occurances. Only, they should learn to make a better use af translation machines. :-)

Pjie2 wrote, are you missing the trace from 30th May Yes I did. Nevertheless, is the water is already fluid at -1,8 ºC while warming up we rightly can assume it isn't fresh water, can't we? For sure the mass of water coming from the Colville has forced temperture upwards, still, a mix of salt water with fresh water remains brackish (or briny) water.
Talking about Alaska's Colville river, look at Permafrost melting at Colville River Bluff to see a devastating result of melting permafrost.
GOL wrote: above -1.8C? This has to be rather fresh water How come? The chart indicates -1,8 ºC and not above. And fresh water freezes at -1,8 ºC, doesn't it? All the more as the “suddenly” Jim talks about spans from 5th May till 24th May. And as we all know, the “heat wave” hitting North-East Alaska and the Mac Kenzie region began around the 1st of May. So defenintely it's sea water there, or, to be more specific, briny water due to the fresh water coming from the Colville and other off coast running melt water.
The Pacific and central parts of Alaska look bound to be baked too. So already now we know 2015 will be remembered as a hell of an inferno ... Unusually hot and dry weather will settle into southcentral Alaska beginning Friday through the weekend. High temperatures will stretch from the mid 70s to mid 80s throughout the region with the hottest day likely occurring on Saturday. Sea breezes which usually moderate afternoon temperatures will be limited during this timeframe. Also periods of gusty winds in Seward, Whittier and Valdez will aid in warming temperatures even further.

Jim Hunt wrote: The buoy is located on landfast ice in the Beaufort Sea near Prudhoe Bay: The picture coming from camera 2 is even more impressive. 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 ...
