This to underline my last post on the topic of Barrows ice-blow-outs and blow-ins.


@pearscot

Ha, I did see your post the other day commenting about how this was possible and I was surprised to see the ice roll in with the fog yesterday! Once again, this is yet another new thing I have seen this year. I wonder how long it will be there until it's blown out to sea again?

Will you believe me that this happens almost every year?

At least it was like this last year as well but then sometimes we discard things from
our upper drawer in the brain as long as they do not appear important enough to keep them there

 ;) ;) ;)

It means efficiency and is totally ok, after all we cannot increase our SSD storage as needed LOL

Have a good day.

I noticed the door was closed and maybe that's why the ice is back in.  ;)

Anxiety justified in this case.

Ice is forming some peculiar patterns in Foxe Basin.

Also, there is an optical illusion that makes some of the ice flows look like large ice bergs with a long shadow. (The "shadow" is just open water.)

Following up on that with a GIF - 10 day walk through of imagery.

The margin of the pack appears to be retreating north at the rate of almost 50km/day.

Some of it is movement, some is compaction, some is ice simply disappearing, possibly because of warm water being blown north.

Insane...absolutely insane. If it is indeed melting/retreating that much per day, that means that its average velocity northward is 1.29mph...

(OT)
When global warming continues and once temperatures in the ESS are moderate, wouldn't this be an exotic tourist destination with long sandy beaches (of course some infrastructure is needed until then)?
(OT end)
Thanks for that finding. Beautiful sequence, impressive meltout.

Phytoplankton Bloom in the Barents Sea

Quote
Clear skies over northern Russia and Scandinavia reveal magnificent swirls of blue and turquoise in the Barents Sea. This true-color image, captured by the NOAA-20 satellite on July 30, 2018, shows a large phytoplankton bloom, made up of millions of tiny plant organisms that thrive in the nutrient-rich waters of the Arctic. Phytoplankton blooms are common in the Barents Sea in late July and August, thanks to a combination of 24-hour sunlight, minimal ice cover and relatively warm surface waters.

Looks like wave-driven erosion to me, same as you would see on an eroding coastline with a hard layer over softer substrata.

Salty warm waters melt the ice faster than cool air, especially with wave action, wind drift and currents involved.

You can find this phenomenon with ALL Icebergs (until they topple due to center of gravity shift) and it's the same here

I guess those are made by the tide. The clumps of ice are stranded and at every high tide the ocean nibbels a bit on the ice. The walruss propably entered the lump of ice during high tide and when the picture was taken, the tide was low.

Sorry but NO !

It's a known phenomenon as explained upthread.

Once something is grounded there is always some list (99.9% which is why more than one, meters appart, only in theory can exist but in real life won't happen)

Indeed. Besides, the vertical tidal movement in Arctic waters is way too small, at max some few tens of centimeters.

I guess the image is from the CAA, where there is hardly any tidal surging taking place. Compare this to e.g. the Hebrides or the British Columbia coast where the tidal movement causes massive surges in narrow channels. Such surges are nowhere to be seen in the CAA, only at best som shlight shifting back and forth.

binntho, maybe I misunderstand something here, but in the linked article tides up to 15 meters height difference in Hudson strait, 2,8 meters in Landcaster Sound and so on, are mentioned. https://www.google.com/search?=ALeKk00XGx5AW8xlrorIgQSJ_bTM9o0Y-Q%3A1595577370896&ei=GpQaX86hNtLLrgTkhaPQBg&q=canadian+arctic+tide+measurement+techniques+and+results&oq=canadian+arctic+tide+measurement+techniques+and+results

Looking at tidal charts/measurements as well, gives me vertical tide movement way beyond your estimates. https://www.waterlevels.gc.ca/eng

What am I missing here?

It seems that I was the one to be missing things. But to clarify, Hudson Strait is not in the CAA proper. When I wrote the above I was thinking of the tidal effect between Greenland and Svalbard, which is 20cm if I remember correctly, and disappears almost totally in the Arctic ocean itself - but again nowhere near the CAA.

Anyway, I found a better image than the one I've usually looked at, as can be seen, the tidal effect is very large in the northern Atlantic south of Iceland, and in the North-West Pacific. Fairly large in northern Baffin Bay but dissipates quickly in the CAA.

It's bigger than I thought, but still there are no surges of the kind seen in the Hebrides and the coast of British Colombia. Perhaps for a surge there needs to be a large effect on both ends of a channel?

There's a topic on tides where you can take this further, but I won't join you there, my contrariness vs. tides is well known and it will only raise my bloodpressure even further if I start to write about tides any further!

Yeah, I very much doubt it's in the CAA proper, with the Greenpeace ship in the background. But surely someone can find the source?

Edit: and that someone would be me.

I think most folks who click on this "Arctic Image of the Day" thread think they are about to see an image from the Arctic.  There are lots of threads for discussion... (but thanks, Yuha, for the link - ah, exceptions!  :)).

Yeah, and the farms kill the wild salmon and their residues even have an impact on such events.

Kind of natural justice apparently.
