For those beating the “imminent Arctic ice death spiral” drum, 2013 has not been a good year. Per the graph above, Global Sea Ice Area has been stubbornly average in 2013, Northern Hemisphere Sea Ice Area Anomaly had its smallest decline since 2006;

and Arctic Sea Ice Extent has remained within the 30 year (1981 – 2010) “normal” range for the entirety of 2013:

Conversely, Southern Sea Ice Area is within striking distance of a record high;

and has remained above average for most of the last two years;

while Antarctic Sea Ice Extent has remained above the “normal” range for much of the last two months:

However, these facts haven’t dissuaded desperate “imminent Arctic ice death spiral” advocates from trying to promote their narrative. Apparently their new angle is Gathering Walruses, i.e.:

“An estimated 10,000 walrus have come ashore on Alaska’s northwest coast, the National Marine Fisheries Service reported, as the sea ice the animals normally rely on to rest continues to melt at alarming rates.” NY Daily News

National Geographic and CBS News add flavor to this gripping tale:

“An estimated ten thousand Pacific walruses have huddled together on a remote island in the Chukchi Sea (map), an unusual phenomenon that’s due to a lack of sea ice, experts say.

The giant marine mammal is known to “haul out”—literally haul its body onto ice or land to rest or warm up—on various places along the Arctic coast.

But with the Arctic warming up and melting much of its floating ice, there are limited areas for the walruses to gather. This forces them to cluster on land in huge aggregations rarely before seen.” National Geographic

“As temperatures warm in summer, the edge of the sea ice recedes north. Females and their young ride the edge of the sea ice into the Chukchi Sea. However, in recent years, sea ice has receded north beyond continental shelf waters and into the Arctic Ocean, where the water is 10,000 feet deep or more — too deep for the walruses to dive to the bottom to feed.

Walruses in large numbers were first spotted on the U.S. side of the Chukchi Sea in 2007. They returned in 2009, and in 2011, scientists estimated 30,000 walruses had come ashore along one kilometer of beach near Point Lay.” CBS News

However, it seems that the “experts” National Geographic cite didn’t have an opportunity to visit the WUWT Northern Regional Sea Ice page. If they had they would have noticed that this year the anomaly in Chukchi Sea Ice Area was the smallest since 2001;

and Chukchi Sea Ice Extent is currently more than 300,000 sq km greater than last year:

It would seem that, rather than “an unusual phenomenon that’s due to a lack of sea ice”, the Walrus Gathering might be due to the increase in Arctic Sea Ice Extent.

For reference, there were also similar increases in Sea Ice Extent in the East Siberian Sea,

Also interesting is that, in addition to the Chukchi Sea, a several Northern Polar regions saw their smallest Sea Ice Area anomalies in the last decade including the East Siberian Sea;

both had their smallest anomalies since 2004, and Arctic Basin Sea Ice saw its smallest anomaly since 2005:

If this is what an “imminent Arctic ice death spiral” looks like we might need to invest in more icebreakers to help keep shipping lanes and drilling rigs ice free, and to make the Arctic more hospitable to those Gathering Walruses…

Not true since this year it reached zero as it has for the last decade plus!
Also interesting is that, in addition to the Chukchi Sea, a several Northern Polar regions saw their smallest Sea Ice Area declines in the last decade including……. the Sea of Okhotsk:
Also not true since it also reached zero as it always does!
Additionally, the Canadian Archipelago; and Laptev Sea; both had their smallest decline since 2004, and Arctic Basin Sea Ice saw its smallest decline since 2005:
The CA is in a ~tie with 2009 and 2005, Laptev Sea reached zero again like it has for the last two years and the Arctic Basin was lower than 2009.
So you appear to be misreading those graphs.

“Gambell usually sends its hunters out in small boats
for a month when walruses float by
each May and June.
But this year, the hunt lasted only about a week. ” (due to ice)

That same article notes that this single “norhtern” village kills something like 800 walruses each year. Let’s see, hmmm…10 villages not killing 800 walruses each, because there was too much ice to maneuver walrus killer boats. If my stupid ‘denier math’ is correct, that would be 8000 walruses not killed this year. Perhaps the gathering is explained by the fact that village hunters killed several thousand fewer walruses this year because the thick ice prevented them from hunting.

It makes me nuts that they can’t get the label right (intentional?) on the Antarctic Sea Ice Extent, Here is a corrected version:

FYI the Hudsons Bay Trading Company did not fold. In fact it is still a major brand. It is currently the oldest commercial corporation in North America. Not to mention that it just purchased Saks of 5th Avenue.

Anyone know whether the sudden reversal in sea ice gains evidenced by Norex graphs is real or more data massaging?

,
Another “5-year slide” is far less likely now that the PDO is negative.
Sometimes just because you find what looks like a pattern doesn’t mean that the pattern isn’t about to change.

THANK YOU! This is something that drives me nuts every time I look at the Sea Ice Page. I too am suspicious of it being intentional.

This happens every year in late summer for the annual moult.
http://www.bbc.co.uk/nature/life/Walrus#p00dhn58
The video explains that the walruses allow blood to flow to outer layers making their skin turn pink. Take a close look at the picture in the NY Daily News link above.

“But with the Arctic warming up and melting much of its floating ice, there are limited areas for the walruses to gather.”
?? Alaska? limited space?

It is unfortunate that there is no data for Antarctica since the gov shutdown. I had the impression that the sea ice extent was headed for one more uptick prior to the onset of spring.
At least JAXA has their own set of Arctic data to show the daily change. The Arctic is rebuilding it,s icepack rapidly.

This is really semantics, in that by “decline” I was referring to the “anomaly” versus the “area”, which obviously cannot decline below zero. This does not change the point that the 2013 Chukchi Sea Ice Area Anomaly was the smallest in the last decade, and the observation that, “Walruses in large numbers were first spotted on the U.S. side of the Chukchi Sea in 2007. They returned in 2009, and in 2011″ indicates that Chukchi Sea Ice Area Anomaly was unlikely to be cause of the Walrus Gathering behavior. Regardless, for accuracy and clarity I’ve replaced the word “decline” with the word “anomaly” in the article above.
Semantics aside, one would think the walruses aren’t concerned with anomalies, they’re concerned with whether there is ice in that region and there has been an ice-free period since about 2002 excepting 2006 per your chart. Nor would one expect Chukchi Sea walruses to be particularly concerned with ice extent in the Antarctic, but perhaps I underestimate them.

Thanks for the facts, “Just The Facts.”
I think the arctic was the last refuge of Alarmists, and they were clinging to a hope this would be the year there was no ice at the Pole in September. A very good Alarmist post expressing this view, containing wonderful satellite shots of ice cracking in the Beaufort Sea last February, and also logic that proved to be faulty, was written last March and has not yet been deleted at http://thinkprogress.org/climate/2013/03/23/1766011/ice-breaking-news-2013-arctic-freezing-season-not-what-its-cracked-up-to-be-literally/
Well, they were wrong. Now they have to pay the piper. However they blew their budget in Bali.
Besides the facts you, (and Anthony’s supurb “Sea Ice Page,”) (It should be called the “Sea Ice Book,”) make so obvious, there are an increasing number of excellent cameras clicking pictures from various parts of the arctic. Even a layman like myself can see what is happening with ordinary eyes, and even before this year’s remarkable turn-around I could see much of what the media was portraying was balderdash.
The media hoopla made over a knee-deep melt-water puddle around the base of “North Pole Camera Two” was a typical example of exaggeration turning to embarrassment, as the puddle drained away in a matter of hours just before a somewhat amazing mid-summer cold-wave had the North Pole Camera producing bone-chilling views that utterly destroyed any illusions of an “ice free” Pole.
What can the Alarmists say? You cannot call the camera the “D Word.” And they would have to be completely desperate to de-fund the cameras, at this point.
Besides cameras, there are some decent people working very hard to increase our understanding of the arctic. On occasions I’ve fired off emails, and received polite and lengthy replies from various “climate sites,” replies that were “just the facts” and avoided the lunacy of politics. I found this hugely reassuring, for, to be frank, I half-expected replies that were political balderdash.
These hard-working scientists have come up with better cameras and some interesting gadgets that are likely to create new data for the Sea-Ice-Page. I can hardly wait for the data from a gadget that runs up and down a cable hanging beneath sea-ice, repetitively reporting data from various depths.
The fact of the matter is, the Arctic is a fascinating place. For example, everywhere else weather systems go around the earth, only occasionally looping grandly into cut-off systems that stall for a short while. The arctic has rules of its own, for it has run out of room to go around and around, and while there may be times when a vortex sits right atop the pole, quite often systems are going across the pole, making a mess of our more ordinary circular logic.
I look forward to a day when we can get back to just watching in awe as weather reveals Truth to us. Politics has been like sewerage in the clean water of science, and the sooner we are rid of such pollution the better. In the meantime it seems wise to stick to the facts. In the end it will be the facts that defeat Alarmists, more than our moaning and groaning over their balderdash.
Have you checked out the recent film produced by O-buoy #7? In ten days it went from open water to snow-covered pack-ice. (See picture towards bottom of my post at http://sunriseswansong.wordpress.com/2013/10/05/arctic-sea-ice-recovery-diary-the-deepening-twilight/ ) In the end, a picture is worth a thousand newspapers, and facts speak louder than words.

Umm, no, there was clearly no ice-free period in Chukchi Sea this year and I am not sure where you drew the Antarctic Walrus connection, did you miss this graph in the article above?:

According to the Cryosphere today data that you displayed in the original post the Chukchi Sea was indeed ice free this summer, the small difference in anomaly you changed to just means that the ice receded about a week later this year! That still means that the existing ice was off shore over deep water where the walrus can’t feed (as described in the article), and they do care about that. Check out a bathymetry map of the Chukchi Sea.
The difference between ‘anomaly’ and the sea area is not just semantics, in the case of the regions where area drops to zero the change in anomaly is really a measure of the timing of the ice melt.

I stand corrected, there was merely about a 99+% ice-free period in the Chukchi Sea this year as there has been for most of the past decade. The point being that they hypothesis that the walrus are beaching on land because there isn’t substantial near shore ice is consistent with the ice observations you’ve presented.

So now we have to worry about anecdotal evidence about disapperaing walruses??
Oh noes! Just like the polar bears!

As a follow up, I was having a hard time reconciling the “Region 2 plot Chukchi Sea” (ftp://sidads.colorado.edu/DATASETS/NOAA/G02186/plots/r02_Chukchi_Sea_ts.png) with the “Current Chukchi Sea Ice Area” (http://arctic.atmos.uiuc.edu/cryosphere/IMAGES/region.all.anom.region.10.jpg) which appears to go to zero at the annual minimum. Clearly they are plotting two different things. Poking around a bit I found the former plot is the area bounded by (65.37,-156.65 ; 66.00,-180.00 ; 80.00,-180.00 ; 80.00,-156.48) and the latter apparently includes only the sea area bounded on the north by Wrangle Island at about 71 N latitude). Taking the two together suggests that whatever ice remains at minimum is generally in the Central Arctic Ocean rather than over the continental shelf which is confirmed by looking at sea ice extent maps.

Has the government shutdown also shut down NSIDC and U of Illinois’s Cryosphere Today. Why is it when momentous changes are afoot that are embarrassing to CAGW proponents, the graphs all stop and apparently decide some metric needs to be added to (sea level), temperature fudges as new versions, etc. We are just at an Antarctic satellite era record ice extent and a galloping recovery of the Arctic ice extent when they shut down. What are they going to do with these inconvenient data now?
