Something special. Go to the Barrow webcam and download the image to your desktop. Open the image and magnify to full screen. What you'll see then just in front of the horizon is “the pack” now drifting towards the beach - if wind direction would persist the entire mass would crash onto that beach. CFR this UNI-Bremen map too.
Looks like this year's final stage will start at 30th July. Then a (meteorological) depression is supposed to take in the central Arctic. Sending from 1st August a series of warm precipitations from over Wrangle Island to the Beaufort Sea and the North Canadian archipelago. cfr the weather reanalyser.
[A reply typedad induced belated] NeilT wrote More interestingly is what is happening off Banks Island and the Canadian/Alaskan coast .... but a quick look at o-Buoy9 tells the tale of what is going on. Not exactly, as Obuoy 9 already has entered the Fram Strait and probably even already has passed Station Nord. Yes, Obuoy 9 travelled al the way from the East Siberian Sea to the Northern coasts of Greenland and so further on to the Fram Strait. Meaning, what we see at Obuoy 9 is the Northern part of the Greenland Sea with it's large polynia visible at the UNI-Bremen maps. Anyway, Obuoy 9 will show us unprecedented images from the Fram Stait as well as the Greenland Sea...

Remember, in 2012 mid July we had about the same situation as it is now, with the difference now the Beaufort side is even more fragmented. Remember, in 2012 the turning point came with “the storm” in early August, a cyclon which scattered the entire Arctic apart. So, “to storm or not to storm, that is the question.” And to be sure we'll have to wait till August as usually only then this type of cyclons can enter the Arctic.

Jim Hunt wrote: ...depends upon the ice class of your vessel... Indeed. Back in 2012 [IIRC] there was some commotion when from June on the Russian government introduced a regular traffic of mammuth tankers from Murmansk to the East, over the North-East route of course. Tankers escorted, preceeded, by the atom ice breaker Jamal. Moreover, from 2017 the traffic will be continued all the year around when a new atom ice breaker will be ready, an atom ice breaker custom builded to the job. Other than that, already in 2009 the Jamal escorted two German cargo ships over the North-East route to the Bering Strait. Bottom line, this isn't even an issue anymore. Incidentally, some of the Russian mammuth tankers are ice breakers as well, and we really don't know what they are doing all the time, do we? :-)

1st Century this year: 9,731,983 ---> 9,627,576. Or do have a look at https://ads.nipr.ac.jp/vishop/vishop-extent.html?N
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.
Tanaka wrote: ... the Larsen B they can grow to be a dozen meters deep before they breech and drain I'm afraid yo are underestimating what was once upon a time Larsen B. 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.
