Nice detail, Espen, that bathtub always appears first in Nares' spring, doesn't it?

I liked todays trembling atmosphere in the wake of the De Long Islands, N of the Novosibirskye Ostrova:



Bennett Island always ripples best being 426 m high, but today Henrietta and Jeannette Islands joined through their 315 and 351 m rocky outcrops.

I wonder if the wide stress lead along the East Siberian Continental Plain plays a role. The southern winds crossing them pick up moisture over there (see the upper right corner). It condenses when the top of the boundary layer is lifted over these cliffs.

In that case, it is a sign of spring and anomalous moisture spreading over the sea ice...

Wipneus.....interesting snow cover pattern (I'm assuming that's what I am seeing.).

Is this pattern caused by patches of open water in the delta, still covered with ice and snow, which are surrounded by less wet and perhaps vegetated areas?

Possbly that's frozen marshland, the more solid patches of ground have lost their snow...

A rare sighting, Bouvet Island the most remote island and controlled by Norway.
By the way it is the national day of Norway (May 17th):

http://en.wikipedia.org/wiki/Bouvet_Island

93 % of the island is covered by a glacier, I wonder if Mauri covered this one?

First thing I noticed as well when the Lance Modis opened the "curtains" of today! Very massive scale, I Guess we can't blame a herd of Narewhales for this incident ;D. Will be extremely exicting to see if this cracking will continue and even more to observe if these openings will continue to grow and allow the sunrays to heat up the darker water in between the ice :).
My fancy for ice & glaciers started in 1995:-).

What do you see here?
Well, what I see is a lake (the Laptev bite), with kind of the shape and possibly the size of the United Kingdom Island, in a place that we would not dreamed ten years ago. But the Arctic sea ice is OK. At 2014 we are far from reaching the 2012 record, so we have to wait until all the Arctic sea ice is gone, in order to believe that AGW is happening. Anyway, thanks to Global Warming, we have new maritime routes at the Arctic.
Yes, I am being sarcastic. Isn't this reality bad enough? We should wait until the permafrost will melt, releasing methane and CO2? In my opinion, this waiting time until we reach another record is a waste of time. There should be a special place on this forum with the name "We ought to..."

Which is the best answer to Sep-2012 ASI lost (compared to 1979-2000)?
50% [NSIDC Extent] or
73% [PIOMAS Volume]

Volume is harder to measure than extent, but 3-dimensional space is real, 2D's hide ~50% thickness gone.
-> IPCC/NSIDC trends [based on extent] underestimate the real speed of ASI lost.

Thanks for the link, trebuh.
In a way, you show me I am right in my comment.
It is true that we had an important Laptev bite at 1990, but the sea ice at 1990 was strong, so it didn´t develop the way it is going to develop at 2014. On the other hand, if we check the other years, there was not an important Laptev bite until 2007 and 2012 (2009 has no data).
In a way, I am dissapointed that I asked for an action in this forum and some forum users answered that we should not have "we ought to..." proposals on this forum.
Surely I was not active enough. I should push harder.
Anyway, the true is that at 2013, the IPCC was critized for exagerating AWG, when my point of view is that it is the other way around.

What do you think? Do you agree that the IPCC models, as they are right now, are worthless? Would you like to make the effort to include a PIOMAS volume forecast on the USA Third Climate Assessment Report?

contrast-enhanced MODIS-image of an arctic specialty, poorly defined mesoscale cyclone (weak 'polar low') inside an otherwise uniform cloud cover (or that's my interpretation). They do not usually produce significant worsening of weather conditions, if they're the same that pass Finland occasionally, rather you note thicker clouds and a slight increase in precipitation and winds, lasting at max some 15-30minutes, or these happening a couple of times during the snow event. ('tuisku' or 'tomakka' we might call the stronger ones in finland, the 4th worst type of snowstorms that some people still enjoy)

resolution 250m/px so the system size is just 75km :-)

Localized, yes. generalized, and at this scale, no. This is a new phenomena, directly tied to increased high latitude heat and drying.

Looking at that this morning, the thing that struck me was how quickly the shards of ice shrink as they are ejected to the south west - ice islands the size of Manhattan just vanish in a couple of days.

On a peripherally related note... I think maybe there's a flip side to the lack of Fram transport over the past few weeks. If the sun is shining on all that open NA/GS water, and there's no ice melt to cool it, is it just storing up heat which will either end up either migrating west under the ice - melting as it goes on the one hand, or causing rapid melt of future
eastward-migrating ice on the other?

Trying to think of a way that sunshine on open water doesn't store up trouble for later - but rolling a doughnut here...

Anybody fancy a golf day in the Arctic?

Hey Seattlerocks,
That's my mini-cyclone on this thread:

A detail that is of interest within the fog-low cloud discussion.

This 10 km diameter swirl is visible on MODIS today:




Yours is from a later MODIS-run; diff probably 3-6 hours. The swirl made 60 km to the South and has lost it's vorticity. The 'contrail' is delusive; it doesn't emerge from the 'golfball'. Though it looks to be flowing North, the band seems related to the clearing of the fog/low clouds to the SW.
It looks like a diurnal process in action.
The exposed ice looks worse than before. Many pothole-polynia's are appearing, remaining snowcover is rapidly melting away and exposing the individual floes. On top of that, the floes turn a 'deeper shade of grey-blue'.
Soon, the Laptev Bite may expand deeper into this region.

A little OT:

Liftoff! OCO-2 Heads to Orbit

July 2, 2014 --  A United Launch Alliance Delta II rocket launches with the Orbiting Carbon Observatory-2 (OCO-2) satellite onboard from Space Launch Complex 2 at Vandenberg Air Force Base, California. OCO-2 will measure the global distribution of carbon dioxide, the leading human-produced greenhouse gas driving changes in Earth’s climate.

Image Credit: NASA/Bill Ingalls


The Permian–Triassic extinction event, a.k.a. the Great Dying, occurred about 250 million years ago and is the most severe known extinction event. Up to 96% of all marine species and 70% of terrestrial vertebrate species became extinct; it is also the only known mass extinction of insects.

Yes, it's fascinating to watch. Here's yesterday's shot upstream a bit from your shots. You can see that another chunk has broken off. And further up, at the top of the strait, there's open water and very thin ice, suggesting that the whole thing will likely go pretty soon.

Is this rare or a normal phenomenon in the Arctic? I wonder what drives power to the vortex

Edit. I just read your post in the other thread so nevermind. It is really amazing

I would have interpreted it as a polar low birth if I'd seen it just on one image but now I'm not anymore sure. I do not recall seeing anything this small persisting for so long (occasional checks of MODIS images since 2008.) Could be a new sort of phenomenon. Association of mid-size cumulus-clouds that could grow in to a supercell or two in lower latitudes but here up north there's no chance for that to happen? Weird.
