Wayne - 2015A is a "seasonal" IMB buoy. Diagrams are available here: http://imb.erdc.dren.mil/SeasonalIBinst.htm and in this paper: http://imb.erdc.dren.mil/pdfs/SIMB.IGS.Final.pdf
Wayne - If by "schematic" you mean what we call a "circuit diagram" over on this side of the Atlantic then I'm afraid I don't. How would having one help?
Bill - Well, Anne Quéméré is going to attempt to kayak through the Northwest Passage once again, following her abortive attempt last year: http://www.anne-quemere.com/?lang=en A couple of years ago I spoke to Anders Bache of the Fram Museum in Oslo, who assured me he knew of a team planning to kayak to the Pole itself. http://forum.arctic-sea-ice.net/index.php/topic,116.msg1621.html#msg1621 Who knows, maybe this will be the year?!
Robert - That's the northern end of the Nares Strait, through which flows lots of water. I posted a similar image recently on the ASIF forum: http://forum.arctic-sea-ice.net/index.php/topic,176.msg52621.html#msg52621 We're idly wondering over there when lots of ice will start flowing through it also. P.S. Another pretty picture of mine has been stuck in your moderation queue for a couple of days. See the one above.
Kevin, Forget the differing dates and latitudes. Consider the temperature profiles. My point is that even when an ice floe has become "isothermal" as far as the thermistors are concerned it doesn't vanish overnight, or even in two weeks. Do you fancy a little flutter? ;)
Kevin - I did say "just yet"! Have you seen this temperature profile from last summer? http://GreatWhiteCon.info/resources/ice-mass-balance-buoys/summer-2014-imbs/#2013F Buoy 2013F is still with us this summer: http://GreatWhiteCon.info/resources/ice-mass-balance-buoys/summer-2015-imbs/#2013F
Wayne - I've never been able to tie up the thermistor and bottom sounder readings from 2015A satisfactorily, since the sudden jump in April at least. Here's the latest temperature profiles: Click the image for a closer look. Based on the thermistors I see no evidence for an inrush of warmer water or the sudden onset of bottom melt. Whatever the bottom sounder pings were being reflected off seems to have gone. Other than that, the core temperature of the floe is still below "melting point", so I don't expect to see any sudden changes just yet.
Kris - That camera is looking at IMB 2015B, currently located in the Chukchi Sea. Much more info at: http://GreatWhiteCon.info/resources/ice-mass-balance-buoys/summer-2015-imbs/#2015B
A picture of Seasonal Ice Mass Balance Buoy 2015A sitting in the midst of melt ponds. The buoy is located on landfast ice in the Beaufort Sea near Prudhoe Bay: Click the image for a closer look.
OK - Thanks Bill. Another time it will have to be :( Will I get free beer if I mention your name?
If you're still around Bill, do you fancy a Pint of Science in Exeter this evening? Ben Bradshaw and then Andy Williamson have stood me up and hence I have a spare ticket and a pint on offer! More info at: http://pintofscience.co.uk/event/unzipping-your-genes/ An initial report on last night's event can be seen here :) https://twitter.com/jim_hunt/status/600600280619679744
Neven - Thanks very much for the link to GWC. Here's my response: http://GreatWhiteCon.info/resources/about/#comment-209506 It looks suspiciously as though you were one of the very first people ever to go swimming in Santa's Secret Summer Swimming Pool!

Neven et al. Do you believe the evidence of Landsat 8 plus your very own eyes? A large floe in the Beaufort Sea yesterday: Click the image for the bigger picture.
Bill/Neven, "Might it also be an idea to include on the ASIG page some links to resources other than graphs or datasets?" Might be an idea for GWC also. What does the team think should be on the list? In the meantime I'll get even busier...... http://GreatWhiteCon.info/resources/arctic-sea-ice-explanations/

Neven - Any chance of a monthly "Open Thread" again this year? Chris et al. - After a long winded and extremely unfair fight between Snow White and Willard Watts all her words and moving pictures of wisdom are now simultaneously available via both ATTP & WUWT! https://twitter.com/jim_hunt/status/600054730388283394

Welcome back to Blighty Bill! VISHOP is down. Back RSN apparently: http://forum.arctic-sea-ice.net/index.php/topic,1112.msg52160.html#msg52160

Thanks for all your hard work on the ASIG Neven! Just a reminder that for the last few weeks I've been updating the Great White Con resources section :) This part is particularly interesting just at the moment: http://GreatWhiteCon.info/resources/beaufort-sea-ice-graphs/ By way of example: Click the image for a larger version, including the Chukchi Sea also.

Bob - Do you recall that there is an Arctic Sea Ice Forum? For a slightly more sober assessment see for example: http://forum.arctic-sea-ice.net/index.php/topic,1149.msg51489.html#msg51489 et seq.

Sam - Here's a video using Hamburg Uni AMSR2 showing the Beaufort end of the events you describe. It's not quite up to date: https://youtu.be/p8_XUBdyQls However this Landsat 8 image from middle of the Beaufort Sea in the middle of May is: Click the image for a closer look.

Chris et al. Hopefully you'll find this amusing too: https://twitter.com/jim_hunt/status/599904517270941696 The Great White Con meets WUWT in an unfair fight! Episode 11/n. Archived for posterity.

You're on Chris, assuming that you're happy with "below 1M km^2 on any day before December 31st 2022". "Chilly" will no doubt be pleased to hear your analysis. You may wish to contribute to our discussion about the "small print" of the wager. I cannot help but feel that you have a better appreciation of some of the subtleties than him. Win or lose my charity of choice is ShelterBox, who are (unfortunately) currently in the news again: http://GreatWhiteCon.info/2015/05/the-new-normal-in-the-arctic/#comment-209003 I haven't heard anything back yet from either James Delingpole or David Rose. Perhaps I should try and find out if Christopher Booker fancies a flutter next?

Interesting Kris, thanks. However that lead isn't exactly "brand new". Here's how things looked on July 31st last year: http://GreatWhiteCon.info/resources/arctic-sea-ice-images/summer-2014-images/#OBuoy9

Wayne - I've been having a chat to the CRREL about 2015A, amongst other things. They tell me: The top temperature sensors are indeed heating up from the sun. If you look at it closely - you can see that they track the air temp, very well most of the time. These readings are every 4 hours. And if you look closely you can see that each day, the 20:00, 0:00 and 04:00 readings are always higher than air temperature and also would correspond to when the sun is beating down on that side of the buoy. A more detailed report is available on the forum at: http://forum.arctic-sea-ice.net/index.php/topic,1149.msg52001.html#msg52001

Chris - Thanks for the Siberian info, such as it is. The Mackenzie flow is now over 20,000. Re my Arctic sea ice wager, the cat has now released the tongue of the original proposer, so that spot looks like it's taken once again. http://GreatWhiteCon.info/2015/05/the-new-normal-in-the-arctic/#comment-209058 I have however also discreetly enquired whether the Mail on Sunday's leading Arctic investigator is similarly willing to put his money where his employer's mouth is.

Chris, Vid was banished from the forum some time ago, so there are now fewer distractions. I'm intrigued by your Siberian researches. Have you uncovered live data, or any data at all for that matter? The Mackenzie data I'm looking at include air temperature, but not water. Flow is now up to 18,000 or thereabouts.
