Pretty sure it's Kostroma near where the river of the same name runs into the Volga.

It is Veliky Ustyug. 60°45'21.7"N 46°19'31.7"E Yesterday it were even airstrikes on ice hummocks

Pretty sure it's Kostroma near where the river of the same name runs into the Volga.

Ice hummocks is a problem of rivers, that flow north, Volga is flow south.

I posted this on the Barneo thread just now but then it occurred to me that it might really belong here.

While going over yesterday’s MODIS tiles, this picture struck me as unusual:



It is a detail of a large icecap on October Revolution Island, Severnaya Zemlya.
It looks much like a ‘Jokullhlaup’.

Now there is a term that could use some more background.  What is the etymology (translated).  How frequently do these sub-glacial water flows occur?  Are they common, uncommon, rare!  Are they known with particular conditions or causes?  It is definitely a noteworthy sight!

You wouldn't see a jokullhlaup from the air.  Reason being, it's under the glacier and you're above it. Pretty sure that what you'd expect to see would be the area in front of the calving front being swept clear by the flowing water - not what you see here.

What you see here is that the glacier surface looks a bit darker than the surrounding ice cap and sea ice.  Far from uncommon, you can see the same thing on many of the Greenland glaciers (and indeed on this one in previous years).  Not sure why, could be the snow melts back earlier, could be the surface is rougher, could be something to do with the elevation and the angle of the satellite.

That's a surging glacier on the Vavilov Ice Cap.

"Jökulhlaup" is from Icelandic, combination of "jökull" (glacier) and "hlaup" (run) - direct translation is glacier-run. They are fairly common in Iceland, where all the larger icecaps are sitting on active volcanoes. Geothermal activity causes regular (every few years) flows in some areas that are comparatively harmless, while eruptions can cause very destructive flows. These flows do not cause any significant changes on the surface of the glacier.

Here is a cloud free Sentinel 2A image, scaled to 40 m/pix, of the end of the MacKenzie delta. River water seems to be streaming over the ice.

Note: this is a false color image with blue, red and near-IR specral bands. Similar to MODIS 7-2-1 composites.

Image from the Suomi-NPP satellite carrying the VIIRS instrument.

Wow, I got almost the same image from the EAVIIRS instrument  (Enhanced Audio-Visible Infrared Imaging Radiometer Suite). Sea ice is returning.

I believe they are from the same satellite.  :) mind sharing a link to your resource?

I'll have to disagree on the sea ice returning.  Looks the the Chukchi is getting massacred.  Perhaps the winds swing around and stop the progression, have to watch and see I guess.

Not an image so much as an animation.

The decline of old ice in the Arctic.



Anyone know how to get this link to work as an embedded image?

Thanks Jim.

Answer, not an image but a link.

Can't find the original FB video at NOAA. The one above is end of March.

The FB video is weekly.

Posted a larger image inclusive of this on the melt season thread.  Lovely is a matter of context, but I get your meaning.  The old region - from Laptev to Chukchi - is in a serious world of hurt.

Blue ice well and truly broken up right in the middle of the ESS fast ice.
I seriously doubt the statement that the fast ice in this area is thick this year. There is no reason for it to be exceptionally thick. It is first year ice made during a winter when temperatures in general have been higher than normal.

thanks, i think the ice thickness and therefore volume calculations need an overhaul. i posted quite a few time my doubts as to their accuracy, i think that they rely to much on the past more than on really actual measurement and calculations and the ESS part was probably an assumption based on the wind drift out from beaufort. we shall see but we should observe the real results to the predicted and reported ice thickness very carefully,

another indicator that something is not quite right and what initially raised my suspicion, is that different volume and thickness images show totally contradictory results, at times almost 100% the contrary.

I found several brownish lines on the blue ice between Victoria Island and the mainland. A few of them  connect directly to Cambridge Bay (a settlement).  Do they still drive on the ice in June or does the dirt remains until the ice fully melts?

Floes have been breaking off regularly in Kane basin for the last month and now we can see the beginning of the break up of Nares strait from the north end.
Sorry this ended up being not what I intended at all. There were supposed to be two pictures not one. the picture showing is south of the Petermann glacier not the north end of the strait.
