Wandel Sea / North East Greenland
« on: June 06, 2013, 12:44:03 PM »
Wandel Sea:

A big piece of sea ice is on the move north of Prinsesse Margrethe Ø / Island aprox. 5000 - 6000 km2 or similar to + / - 90 times Manhattan!

The "Stubborn Hook" at Nordostrundingen will soon be history for this season, beware the first image below is from yesterday!!
The "piece" that went off today is only +/- 450 km2!

Nice catch Espen!
The Spring tide on the 25th was a big one & may have damaged other fast ice areas.

Antarctic Bay / North East Greenland is now sea ice free (just about 150 km2):

Some thick (I assume) ice floes get stranded in the Nord and erode away from there.

Those chunks are from thick ice which was moved on 9th Feb.

Visible in that image, and also more clearly in the image below, is a rather large chunk of ice (300km long in total?) separated from where Independence Fjord and others open out to the Wandel Sea.

A crack is visible in http://ocean.dmi.dk/arctic/images/MODIS/Nord/20170208s01a.ASAR.jpg then 2 days later on 10th Feb they have separated: http://ocean.dmi.dk/arctic/images/MODIS/Nord/20170210s01a.ASAR.jpg

The export machine keeps on humming.

In spite of winter's best efforts, I doubt that any intrepid explorer is going to be able to walk to the North Pole again.

Follow up: the eroding/grinding continues.

Thanks, Wipneus, for the movie.  I was surprised when the several large "white" (old thick, I presume) floes got stuck on the northeastern corner of Greenland a couple weeks ago, as they had been 'nicely' tumbling along near the shoreline.  I wonder if the near-shore sea floor is shallow enough for floes to become grounded (especially if getting 'tumbled' as they flowed eastward), then the northern 'half' got sheared off because of the relentless pressure of 'the lemmings going off the cliff' (or 'ice being exported').
Arctic ice is healthy for children and other living things.

As if all these old floes can't wait. They are simply rushing to get out the Fram

Arctic’s ‘Last Ice Area’ May Be Less Resistant to Global Warming

The region, which could provide a last refuge for polar bears and other Arctic wildlife that depends on ice, is not as stable as previously thought, according to a new study.

New York Times, By Henry Fountain, July 1

https://www.nytimes.com/2021/07/01/climate/arctic-sea-ice-climate-change.html

Last August, scientists aboard an icebreaker that had been drifting with the ice across the Arctic Ocean in a yearlong research expedition decided to take a detour to the North Pole.

They needed to get there quickly, so they used satellite data to find a route where the concentration of sea ice was low enough for the icebreaker, the Polarstern, to push through easily. They found it in an unlikely place, the Wandel Sea, just north of Greenland.

“This area used to be one that was chock-full of this old, thick sea ice,” said Melinda Webster, a researcher at the University of Alaska Fairbanks who was on board for this part of the Mosaic expedition. “It’s not what we encountered when we went through there.”

Scientists have now shown why ice conditions in the Wandel Sea were vastly different last summer. The warming Arctic climate thinned the ice, they say, and an unusual shift in winds pushed much of it out of the sea.

“As it is typically with extreme events, there’s an underlying climate change component,” said Axel J. Schweiger, a climate scientist at the University of Washington and the lead author of a paper describing the research published Thursday in the journal Communications Earth & Environment.

Accelerated sea ice loss in the Wandel Sea points to a change in the Arctic’s Last Ice Area

Abstract:
The Arctic Ocean’s Wandel Sea is the easternmost sector of the Last Ice Area, where thick, old sea ice is expected to endure longer than elsewhere. Nevertheless, in August 2020 the area experienced record-low sea ice concentration. Here we use satellite data and sea ice model experiments to determine what caused this record sea ice minimum. In our simulations there was a multi-year sea-ice thinning trend due to climate change. Natural climate variability expressed as wind-forced ice advection and subsequent melt added to this trend. In spring 2020, the Wandel Sea had a mixture of both thin and—unusual for recent years—thick ice, but this thick ice was not sufficiently widespread to prevent the summer sea ice concentration minimum. With continued thinning, more frequent low summer sea ice events are expected. We suggest that the Last Ice Area, an important refuge for ice-dependent species, is less resilient to warming than previously thought.

And it is not any better this year, within at month the gate into Independence Fjord will be open:
Have a ice day!
