This American has a wife who describes his slow driving as "poodling along". I find it's use as describing a puddle rather charming after many years of my wife describing my driving to me. I will cease my own referencing it now as I take a bow to all the international people here who speak and write in English as I only can handle enough words in German after six years of living there to order a beer and get slapped after I have drunk it and say something uncouth to a fraulein at the bar. Instead I will be quiet and continue to learn about the Arctic from all of you.
That would be "pootling" along!

ice floes → brash ice → water → water vapor   :D

Excellent picture - it would be very interesting to know the SST of the waters in each represented area.

a clear view of the lena delta at this time is always a spectacular sight.

the dark lines aginst a white background are easy to understand, the white lines against a dark backround I find puzzling. Makes a beautiful picture I could look at for a long time.

Just a guess (never been there  :) ) Grey/dark is sea ice flooded with meltwater from the river. White lines are ridges in the ice, still covered with snow?

My guess is the white lines are thicker ice in these estuary like channels.  The dark is low lying land that has become wet.  Since the ice in the channels is thicker it hasn't melted but surrounded with melt water, which extend like fingers onto the seaice.

I compared with a day in July last year.

My interpretation:  With flooding, the ice 'floating' on many of the channels stays on top of the water, whereas the flooded neighboring lowland just had snow that is now melted/washed away/saturated with muddy water.  When these ice ribbons break, they will form impressive ice dams. (Fabulous picture pair, Jay!)

Jay's image is the bottom right corner.  I suspect the bottom left corner has the same cause.  It certainly looks weird though!!

someone was mentioning kimmirut as heavily delayed this year to make his point, don't remember the tread but considering the words i remember and that we are just 3 days later i'd say that this kind of delay, if any, is within a healty range due to weather conditions

the snow on the mountains "IS" almost gone and the ice will be gone within a few days as well, water is dark blue as compared to light blue ponds, hence what we see are micro leads if that term is allowed, at least i don't know any better one, ready to listen to a native who knows a better term for those "holes" in the ice.

We are used to looking at open water, but this is odd because of where it is, off the corner of Greenland headed down the Fram, doomed to reach warm southern waters and then become, well uh, warmer water.

and what we see where ice still ice, counts as 100% Extent LOL while with a bit of bad luck ( or luck, depending LOL) the entire image could count as close to 100% ice covered, obviously without it being the case.

one could post images from all over the arctic nowadays and most of them look very similar to this one as far as ice quality and concentration is concerned.

i'd be very suprised if extent wouldn't drop lke a stone once the 15% are reached over millions of km2 at or close to the same time. let's see, just the entire place looks doomed taking about arctic sea ice only here.

you are totally right just that its sounds like new while that open water is there for weeks already. you can crosscheck with sat-images a month back and even then there was mostly coastal ice (fast ice of some kind ) while farther out one was able to distinguish that dark shadow, at times it even shows in the cloud since the surface color has an impact of low clouds color.

Hard to beat this one from O-Buoy 14. There's been some discussion of it on the What the buoys are telling thread.

that was a bear grunting "land in sight" just to find out that it was a buoy :-)

no they really have to hurry to reach land in that direction before it's all gone

I was looking at this image because of the interesting colors in the Bering Strait.   But then noticed the contrails in the lower left corner.

Jay

Those contrails are large enough to completely shroud the Diomede islands in what would appear to be fog. At present, it is also foggy in Utqiagvik. Worldview of the Bering Strait does not show as many contrails, but does show some. Further, worldview shows wispy clouds that could be the remnant of the contrail blasts shown in the image posted by Jay.

In addition to impressive imagery, the contrails that are being spotted raise questions as to whether or not they cause environmental impacts; and, if so, what are the impacts.

Fires in Siberia. Multiple fires north of Lake Baikal. Some soot from these is sure to end up on the ice. It is unusually warm in the area, as the temperature anomaly map shows.





The smoke is getting worse. A huge pall of smoke:

Smoke may heat the atmosphere but filters the sunlight. I always remember smoke taking the heat from early-season sunshine on a cool day. Soot on snow (with solar radiation) has the opposite effect, may compensate?

Black carbon is regarded as a short lived climate pollutant, but there is some debate as to whether light particles offset the dark particles in smoke to inhibit GHG warming. See page 41 onward in the policy guidance document below:

I am dreaming of the North Pole and Central Arctic Basin full of round ice floes with no square shapes to be seen anymore. Today's thin sea ice in the CAB is no longer capable to survive intact when sea ice floes toss each other (due to winds and ocean currents), turning them all round.   ???

That's a depressing thought. Perhaps they will put it in the ice museum...
