Well done Charles, you will not only recover your investments but get wealthier in the long tun. May you be the envy of the neighborhood! Live long in clear blue wild west air and prosper. Would like to read more about Wadhams latest data . .8 meter average sea ice contrasts with Piomas. I am not a fan of Piomas, but will not largely discredit its info without strong evidence to the contrary.
Mark : "But (2) it must have been at least as free for the ship to have become stuck in the first place (a large sailing ship at that - which would need a lot of open water)" Oy mate, has Erebus and Terror gotten stuck in open water??? McClintock Channel ice was known since Franklin as fierce, un-penetrable. Even in 1903-06, but prior as seen by Hall (1869), McCintock (1854), James Ross (1835) and the ever so always present Inuit, who knew about it for thousands of years, not the least the Bowhead whales being distinct , blocked to swim freely by this ice, from North Atlantic to North Pacific for at least 100,000 years. Going back towards present times, in 1848 , yes, the same year of Erebus and Terror abandonment, James Ross searching for Franklin earlier and first (The Scots cared about their cousins fastest of course) with no less HMS Enterprise, took a look at North Peel Sound and declared it un-penetrable. Shortly afterwards McClure got completely stuck North of Banks Island, had to abandon his ship rescued by another rescue team, who's Admiral leader decided shortly after to abandon their own ships 4 of them, all beset in various regions of the wide open NW passage of now a days. They jumped on the NorthStar a cargo ship moored on Beechey Island, which was then considered the safest point before no man's land barred by sea ice, from that time onwards until Amundsen squeaked by on the other side of King William Island. All this history describes a very difficult NW passage, essentially impossible for commercial shipping. Again unlike today. Franklin's men were opportunistic and skillful, they were last beset in McClintock Channel in mid-September, in recent years you could not get stuck in the same channel all the way past October! Often with ships Captains noticing not one piece of ice to see! So Franklin crew slammed in the wrong ice, so thick and ridged it was a prison, all this ice came from the Arctic Ocean, as it was much thicker then, at least 3 meters thick all the way to Russia. From that time on, information gathered from he most expensive rescue attempt in history, declared the ice of the NW passage as totally blocking the route, until now. Particularly since the late 90's.
It is hardly a rebound, is more like a dynamic meteorological reshuffle of the deck of sea ice. Each melt season has the potential to become a 2007 or 2012 . Strait off stats don't express morphology or compactness, is just a number, a variant amongst many others. Sea ice is far more complicated than an existential one, if an analyst doesn't even consider the shape of the summers melt footprint, the analysis would be close to meaningless. Its not black and white, ice or water, a given year stat should be looked at in a sequence of stats, that is better, this graph for instance: flatly denies a recovery especially with respect o maximas not at all jumping up and down from the zero line. Minimas must be judged especially by shape and compactness, there is ample evidence of an extremely fragile state, about 14 days off from the right "dipole" weather to become an all time low area record. But not reaching the minimum extent doesn't mean that next year will be even better, in fact before 2012, 2011 had stronger ice morphology than 2014. 2006 minima was much more expansive and much healthier than 2014: So it is not a matter of simple ice thickness, (by the way good luck if you can calculate it right, because of tides and other physical variables, over all ice thickness is a very difficult measurement, PIOMAS is a nice try) its a matter of knowing how the sea ice behaves, shifts, coalesces, merges, ridges, how much snow on top, how fast the winds, clouds at all times, direct sun exposure and general atmospheric and sea circulations in 3D! But overall this year was a great melt with a very late thaw flavor, as today's Jaxa attests, there is some freezing overwhelmed by continuous melting. This is a presage for next season, the potential for all minima is kept well alive, despite a blink of the eye analyst may reveal wrongly.
Where is the Arctic Urban heat Island ? Seriously, I wonder if contrarians went to secondary school? Consider 2014 sea ice withdrawing from 71 degrees to 85 degrees North a net 840 nautical miles lost, with wider open water about in longitude, and they trumpet their "its a recovery" sound only not drowned because they count on people not having the time to look at a map. Shameless behavior reveals their intent to disarm reality, to render i acceptable and dumb.
The usual fake skeptics banter rings excessively hollow, in particular demonstrates a staggering level of ignorance. Particularly with respect to 2013, a cloudiest Arctic summer, it had nothing to do with cooling, something as simple as sun rays reflected by clouds over a long term causes cooling, this was 2013. Despite a cloudy summer start going on till beginning of July, 2014 has now huge areas of open water surrounding the remaining pack, a key feature of a great melt. It does not look like a recovery at all, except 2014 followed 2013 the partially melted in place sea ice pack season. If there is any sign of actual cooling it would be seen with sst's and surface temperatures, the latter in August was #1 warmest globally, the former is excessively warm. One would expect some contrarians to posit some semblance of reasoning which may prove their heresy against proper science, but they have nothing but childish bragging often repeated as a tool o fool themselves.
Great late melting action with surface air temperatures lesser than 0 is far less boring as 2014 melt season ends.

Couple of astounding things going about, first the NW passage is experiencing a great NW wind blow event, suddenly opening the main channel a greater deal, but there is still melting in the mix, look at archipelago ice trapped in Straits and Channels melting daily. Second, JAXA sea ice towards East Siberian sea is remarkably disappearing fast very late in the season: Third Cryosphere Today and NSIDC are reporting ice where I cant prove its existence, especially next to Brodeur peninsula, on EOSDIS there is nothing in Admirality Inlet, nothing significant visible flying over by air as well. Yet there is ice reported. Same thing next to Bothia peninsula if you compare with JAXA and EOSDIS. Finally Susan, if the Arctic temperatures change greatly, expect radically new weather to the South. The entire circulation system rearranges itself according to where the heat increases.

Kevin, true enough, but its more like if sea ice that killed the expedition was still there, they wouldn't have found one of the ships. If you look at all historical maps and of course sat data, McClintock channel ice was fierce and scary, prompted Nansen and many others to navigate East of King William Island channel. Now , in recent years even today, ships can zip through west of King William Island. Arctic secrets are revealed by the disappearing ice.
Toggle Commented Sep 10, 2014 on PIOMAS September 2014 at Arctic Sea Ice After many glances I cant really make out a quite a recovery ! May be one should look at archives more often. Say 1984 or 94: not even 2004 or 2009: Note to contrarian, the green areas are less than 50% coverage, and yes, the Northwest passage is open, even large enough to reveal an important mystery literally hidden for 166 years by perineal ice which is no more.

DavidR. 2013 was indeed a pivotal year, but likely an indication of melts to come, whereas it was colder for dynamical reasons, ie it was extremely cloudy all summer long. With thinner ice, the cyclones should take over the summer Arctic Ocean, this should give a respite in compaction and insolation greater melts, I believe it likely that higher surface and sst temperatures would have to progress further in order to compensate for this dynamical cooling. 2014 is the offshoot of 2013, more thick ice at maxima 2014 created a partial return of normal clockwise "Gyre" weather giving the results we know. Contrary to 2013, 2014 had a lot more heating of the Arctic seas, this likely will mean overall thinner ice at next maxima, and a return to 2013 summer weather, especially given the warmer sst's of the North Atlantic and Pacific. Fake skeptics fail to understand the details or mechanics and resolve to propagate the simple look, they want to reach the short attention spans most people have about the Arctic. But most people are smarter than they think. Eventually this dynamical "freeze" will be overwhelmed by warmer Global temperatures, making for an interesting unusual melt pattern we had a glimpse of this season, water gaps will show at the center of cyclones eventually growing in size from within the ice pack. However the tidal currents will quickly cover the gap, suffices to say that many intense cyclones will rip away the consolidated fabric of the pack until there is not much thicker ice left. Expect the unexpected when weather patterns change.

I would not comment on 2014 before the minima is in, that makes sense. And there is very interesting developments, making 2014 very unlike 2013, I knew the greater melting would be late months ago, so it is unjustified to do an autopsy on a living corpse. As far as volume is concerned, Piomas is based on a model of sorts, the sea ice models have failed to replicate recent years sea ice melts. There is a flaw with the models which needs to be discovered. As I watched sea ice bergy bit melt right in front of me in water +0.6 C now over Barrow Strait, I am inspired to say the NW passage through Peel sound is open (contrary to recent prognostications) and that late melting clearly outlines the thicker more consolidated ice as on JAXA is about the same as 2012. To the untrained eye it certainly seems a recovery, but alas it isn't at all. +0.5 C water with warmed up thinner ice spells melting with a capital M. Of which pales compared to sea ice shores with waters +1 to +3 degrees above normal:

has spread out the ice shore pack a lot more specifically in the Russian and European quadrant….
Tenney, "Cyclonic activity still ongoing, folks:" … And the minima is not reached, the cyclonic activity has now really spread out at the ice shores and particularly vulnerable. SST's are staggeringly high in the North Atlantic and Pacific, its cloudy and I see a delay of the minima date along with further surprises.
Neven, time is better spent following the state of sea ice, which is vulnerable to dynamical meteorology at present, rather than trying to explain the Earth is not a table on four pillars. I find those johny come lately experts laughable in their interpretations of refuting the best science can offer. If one really looks at the current image of wide expanses of very loose pack ice, essentially melted well within edges next to wide open Arctic sea but with remnants in extent greater than 15% which result in a wider area and extent numbers. If one really studies, there is no reversing of science well gathered. The problem with AGW is that it is extremely slow process, well beyond the attention span of scammers.
wow, a follow up of my preceding would be North Pacific and Atlantic temperatures, despite a weak or undeclared El-Nino. The minima should be quite delayed because sst's are really very warm. Yes it means also much warmer weather everywhere in the Northern Hemisphere. Of which our best friend, the under studied sea ice is the only thing cooling things down along with winter. Perhaps even El-Nino has trouble starting because the South Pacific is remarkably cooler, and you know who is the cause of cooling over there.

Jim Hunt the ice prophet: "The relevance is, of course, that what's very good for the surf at Point Barrow is very bad for health of the sea ice in the Beaufort Sea Marginal Ice Zone" But its not only the waves Jim, but rather sea and ice higher temperatures combined with a Low pressure system in the mix.

Sam, is the winds, and the channels will concentrate the ice on one side or another, it does not mean that its closed to traffic, which by the way, if these ship mates read me or followed Neven's ASIB would have left later!! Sailors are a hardy bunch following their instincts, but rarely if ever seeking advice about sea ice conditions, they just go into the fog. "Inadiman" Norwegian style. The only one seeking advice was none sailor Ousland who circumnavigated the Pole for a rousing reception back at his home. Neven, Ice is never boring unless the scotch is all gone. :) So far a very interesting year, and the melt pond excuse is very tenuous, now that its a bit colder you'd think CT would stall in ice area loss. I gave up on trying to understand CT results , although very interesting, there is something fishy about Extent loosing less than Area as per right now. Extent overlaps the area, already more compact than last year. The mathematics does not make any sense, unless the melt ponds have melted in colder surface air. I scratch my head, it is still nevertheless intriguing….. but weird….. More open water invites cyclones, already making their return felt, Now is the time when they may disperse ice in wide open water.

Steve , Jaxa 2013 :5,487,870 km^2, 2014 5,489,997 km^2, tomorrow may signal 2014 lesser than 2013, soon to be lower than 2008, likely to compete with 2011. To be fair with 2013, wildly scattered largely with loose pack ice, but CT 2013 had more Area at this time, which does not make much sense. And yes Parry Sound is almost open, albeit small, by a mere 10 miles wide or more, but soon to to be much wider . So much for the clogged NW passage. The Laptev bite increases the ice shore line perimeter significantly, and increases melting. 2014 thaw is beginning to look more important than a mere 2 weeks ago.

John, "Everybody is aware that the models used to estimate sea ice area and extent have limitations. They provide estimates." Ya of course, but missing wide open water 40 by 250 km makes me wonder if these estimates are a bit off at times. The data map which replicates the sat pictures better should give better numeric results. Not sure if year to year comparison applies well all the time, for instance broken ice next to open water is not the same as compacted solid ice next to open water. How did CT missed open water so much? Again it must be resolution problem, not all melt ponds, their grids must be huge in excess of 20 nautical miles. While JAXA may be 16 km. The difference in resolution matters when making a calculation to Extent -Area difference. In other words our analytical skills are compromised if we do this calculation.

Oops CT missed 5000 not 50,000 km^2 in the area presented, but since it has missed so much in one sector, it means that they failed measuring a lot of sea ice area accurately, likely by resolution constraints, by a much greater number than 50,000 for the whole data area. Jim, 2014b was floating in its drill hole since July 31 according to official buoy site. That is hard to fathom, is likely floating since its moving very fast. But they are the experts. If so, we have a good profile of water column temperatures. Very fascinating.

By using Google Earth CT missed 50,000 Km^2 of open water in one archipelago small area as per That is while using their section 40% or so coverage of apparently ice clogged McClintock channel. So wider overall mystery is busted, 20 nautical miles resolution is no match for JAXA depicting the open water accurately.
Toggle Commented Aug 20, 2014 on ASI 2014 update 7: late momentum at Arctic Sea Ice Well John, as you can see, Cryosphere Today has likely grids in Excess of 20 nautical miles, making their maps report bad image of reality. In effect CT is good for very thigh pack ice but not for scattered pack ice, like 2014. Making year to year comparisons more tricky. The proof is in the NW passage. Thanks for the melt pond paper, still reading it, the problem with some papers is that they use science speak as much as any lawyer would write an effusive legal opinion stretching our minds beyond the limit of our understanding of it.

Hi John, for melt ponds to be counted, you need a higher resolution captures. Furthermore, in most places with buoys, the top of ice water melts in the morning and freezes at night. Which should be quite normal for this time of the year at high latitudes. For ponds to be counted it would mean the CT uses early morning satellite data regularly.

Phil, I agree, it seems quite weird and 2014 is very close to be lower than 2013 in extent. Logically 2014 should do likewise. Unless there is a lot of small broken ice packs configured in a way making extent smaller but area greater. Or there is a resolution disparity between the way extent and area is measured. Thanks Jim, 2014F seems strategically placed to monitor sea ice before it breaks up. Or may be there is wider open water near 2013F seen by fog bank at horizon: the sun is to the south south East, its possible there is a fear of further breakup or its plain renewal over a solid pan of ice in order to continue monitoring in the immediate region.
