Arctic sea ice / Re: 2018 sea ice area and extent data
« on: September 21, 2018, 05:49:16 PM »
Took this loop off (to paraphrase Col. O'Neill) but coming back it's nice to see graphs with the current year Jaxa plot superimposed over the decadal plots but does the shape of the current year plots indicate a delayed refreeze this year in some areas or Arcticwide?

.....At least the terminal is not in the Arctic Ocean


From an ecologically point of view that's sound but the intention when conditions allow is probably to shuttle LNG East to it and max out storage capacity before the Winter sets in and at 19 knots the new fleet will make very fast passage most of the time. Conditions off Kamchatka would allow normal tankers to make final deliveries.

Interesting to see that particular cloud formation in the bottom right of this picture.



Anyone studying cloud formations in the arctic?

This is  reminiscent of some features usually seen well in to the melting season and further South. Close up it looks like a carpet pile and am I right in thinking it's streaming away from the area of high ice disintegration

As the Earth nestles like a pea in an electromagnetic pod some scientists are beginning to suspect Earth/Solar interactivity is much more complex.

Nasa's GOLD and ICON missions will attempt to study this.

You can have it in any colour as long as it's blue!


Such a passage is indicative of the ice thickness. One imagines that there must be quite precise mapping of the ice to avoid thicker sections close to the ice breaker's rating.

The Christophe de Margerie, Boris Vilkitsky and Fedor Litke  are all shipping actively now visiting Rotterdam, Thamesport (Isle of Grain), Milford Haven, Dunkerke and Montoir.

http://www.dailymail.co.uk/news/article-5221235/Russia-sparks-fury-trolling-UK-gas-shipment.html

British government denied Russian gas was being used by energy companies in the UK though one wonders about the the technicalities of storage facilities for transfer purposes and whether Russian LNG is subtely different from anyone elses LNG. Do the Brits have gas sniffers like their renowned  tea tasters? :)

....Pity that these ships don't log ice thickness and properties along the way. Maybe they do but it just doesn't get compared with or integrated into near real-time Arctic Ocean sea ice thickness products. Or maybe most are following in the rubble track of a previous icebreaker and the data is of little interest.


Most do not send continuous navigation data either which is understandable but it would nice to occasionally see Mother Nature red in tooth and claw via a ship webcam and watch these magnificent vessels ploughing along in savage conditions at a lot less than nine below zero. :)

 The Christophe de Margerie recently came back through the Northern sea route encountering the ice cover and if unescorted will probably exit Westwards.

Long term plans for the region may involve the use of these expensive icebreaker tankers as shuttles with conventional tankers making final deliveries.

« on: September 05, 2017, 01:41:20 PM »
She dawdled in  the main channel of the passage a few days ago (not sure if she went anywhere near the ice) before exiting the area. Current location in the Davis Stait thereabouts

http://www.sailwx.info/shiptrack/cruiseships.phtml

The view from the starboard camera shows a leaden sea and grey skies almost identical to the starboard view from the Crystal Symphony wherever she may be so if you want an "adventure" cruise in the Arctic getting onboard a Russian icebreaker would seem the best bet.

The Xue Long is soon to exit the Coronation Gulf.

http://www.sailwx.info/shiptrack/researchships.phtml

And keen eyed web browsers will note Irma is bearing down rapidly on several cruise ships. Now that would be an adventure holiday. :)

They might meet the Xue Long in a short while. The Snow Dragon will be the first Chinese vessel to go through the passage. Notable in itself for a great seafaring nation  but also as a test of viability of it as a future trade route.

http://www.atimes.com/article/chinese-icebreaker-enters-canadas-northwest-passage/

What they might think of a large luxury passenger vessel passing by in the other direction is open to conjecture.

Arctic background / Re: Pen Hadow's Arctic Mission
« on: August 31, 2017, 01:56:34 PM »
.....One hopes that these are just rhetorical questions but I still think this venture is in danger of defying reality....

The question of applying the laws of the sea to an Arctic Ocean with it's surface covered with several metres of ice wasn't really thought through at the time. It's a subject along with current icebreaker designs and capabilities (and those in planning) well worthy of a thread of it's own.

Arctic sea ice / Re: The 2017 melting season
« on: August 13, 2017, 07:27:03 PM »
If conditions allow then the other "Snow Dragon" might get there first this year.  :)

Xue Long is an icebreaker however. In that class of vessels 50 Let Pobedy has been to the Pole already this year.

True but the Russian nuclear powered vessel can go through 5 metre ice. Xue Long is only rated for just over one metre and very slowly.  She got very close to the pole 7 years ago so the record "first" for a Chinese vessel is still there to be grasped and in itself would confirm the weakness of the ice this year  in the CAA.

In any event you she could also join a select list of ships that have been trapped by the ice in both the Arctic and Antarctic. :)

The North Pole itself is cloud covered today, but it's starting to look as though Pen Hadow's mission to sail there this summer isn't entirely fanciful:

In terms of the Northern Sea route being open to these ships according to Yamal operations from Sabetta will be year round with the East route being utilized from July to December, The full fleet of 15 will be in operation by the end of 2020, which is a lot of LNG.

Is LNG the most "environmentally friendly" of the three fuels it can use?

Interesting sequence Thomas.

The thing that catches the eye about the 2017 plot is a 'channel' of thinner ice running from the Fram strait towards the Beaufort sea.

What is it?

I don't see a slowdown. I'm looking forward to Tamino's next look into the matter.


The blue plot has the appearance of rough "cobbles" for most of it's plot. There's probably a good reason for that.

The red plot is more erratic and the biggest yearly drop is about 3500 cubic km but there's no section there to compare with the plot of the last 4 years.

How indicative is the dotted average line of what will actually happen in the next few years?

In a humanocentric world when all the ice has gone will scientists be able to predict what the climate will be like not just in the Arctic but in highly populated regions elsewhere?.

As icefree Summers approach expect an increase of such outbursts. Continuing to post pictures and data in such an environment would be like constantly checking your altitude after both shutes have failed.

...Forget the semantics. Admit that global unity is the only hopeful way forward if there is any chance at all. Admit and accept within your own mind that your unwillingness to do everything possible towards real change is tantamount to ensuring the living world will find no way out of what appears to be near total destruction. Can you? ...

As regards climate things might be happening a bit fast for many creatures to adapt but that won't be a first time for the Earth (which is a global unity) I'm sure.  As regards survival of humanity or any other individual species there are no guarantees over the next 10 thousand years.

Nearly there Jim. :)

Could you remove the 2017 plot. The several reasons for this would several. Firstly it's handy for people who don't have access to a colour printer. Secondly it provides absolute clarity about the trend itself  and finally it might help a little to stop people worrying about these figures on a daily basis.

It also takes quite a while for the unscientifically minded to process the volume of information this forum presents when first arriving here.  Some people (of whatever age) need a clear and basic explanation in the title of the graph.

Could you also do another graph with just the 4 dotted line average plots (including the rolling  average of the current decade and extend the y axis down to zero? Any time between now and September will do.  :)

The vertical component of the jetstream and it's impact is by no means fully understood. Current image at 250hPa shows it originating below the equator and maintaining two large looping systems that were previously partially preformed by the polar jet over the Pacific end and the Barents sea.

That's a bit further afield but to my untutored eye the sub tropical jetstream seems appears to have merged with the polar jetstream. How stable or temporary this configuration is I wouldn't hazard a guess but I imagine it would facilitate warm air moving Northwards.

but I think it is because of the direct increase in temperature caused by advection of airmass from the Pacific, may be fooling the concentration calculation. Another (worse) blow is coming in the next few days.
Below the 850 mbar temp anomaly of the last three days (ECMWF), shows very neatly the airmass entering the Arctic


Jetstream maps show a perfect loop forming over the area and in short order too.

These new graphs by Wipneus strike me as among the most compelling climate change images I have ever seen, anywhere.  They appear to me to indicate an unprecedented state change in the global climate system.  Is that overstating the case?  I have been sharing them and will continue doing so but I want to provide the proper context for them.


If peak to trough values are maintained next year then sea ice area will drop to around 15m km2.
