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?

This little bullseye I saw is amazing, but more so is the insane melt happening all over Greenland:
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.
I can't really figure out why the water is such a different color here, but this hue of blue is absolutely gorgeous!

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.
How do those ice mushrooms get made?
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.

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+resultsLooking at tidal charts/measurements as well, gives me vertical tide movement way beyond your estimates. https://www.waterlevels.gc.ca/engWhat am I missing here?
Environmentalists had tried repeatedly to block the Shell project and welcomed the news. Above, a walrus sits on floating ice as the Greenpeace icebreaker Arctic Sunrise crosses the Chukchi Sea
Binntho, do you know where this picture is taken or are you guessing?
