the opening @ 26.02.2018 was much greater .. about 200km open water north of Greenland and 'big block' was in bits .. b.c.

Have you any images at hand for comparison?

sorry binntho .. I have not .. but perhaps now I have .. https://tinyurl.com/ydyv7ch6 ... perhaps not .. Uniquorn describes it as Worldview brightness band 15 .. sees in the dark of winter .. a valuable addition to our winter viewing .. 26.02 2018 has the best view of the megabyte ..

post 1137 2017/18 freezing season is another A-team gift .. worth a look back .. b.c.

Thanks, B.C. for bringing this up.

Very impressive pictures, it's incredible to think that this could happen in the darkness of winter. A gap at least 100km and stretching up to 200km, halfway to the Pole itself!

Feb 2018 - Helluva weather event. At the edge of believability.
But will August / early September 2019 bring a spectacular anomaly of some description?

what's crazy is that all of those meltwater ponds are quite close to the huge gap when has opened up north of Greenland. I think that's the defining component of 2019...

Not sure but I think I remember there was a SSW (sudden stratospheric warming) at the end of feb2018.

The National Oceanic and Atmospheric Administration (NOAA) has been tracking the melt season with aircraft flights over the ice north of Utqiagvik, Alaska, as part of its Arctic Heat program. While onboard some of these flights in mid-July, Kevin Woods of the NOAA Pacific Marine Environmental Lab in Seattle, Washington took several photos of the sea ice (Figure 5c). The ice appeared to be highly decayed with deep melt ponds, many melted completely through the ice. In other areas, the ice was sparse with isolated floes surrounded by open water. Much of this is likely to melt out completely by the end of the summer.

Looks like a helicopter or drone taken image for me but it can be misleading without any point of orientation

good question then, let's wait and see :-D

Edit could even be taken from a very high bridge of a big vessel, i'm curious too.

Yep, possible, any flying object not to high above ground/water level is possible.

Since my English is not perfect at all, is a helicopter an aircraft or does that term only apply to fixed wing aerial vehicles? I was of the opinion that anything that is airborn and powered is an aircraft but i might be wrong

The black line shows where the glacier fronts are (or were). There has been a lot of calving action this year and some glaciers have receded a bunch. I've taken some looks but it's just too depressing to look at in detail.

Stephan · « **Reply #1581 on:** August 11, 2019, 08:31:15 AM »

Maybe Espen will take care for these new features in detail in the Greenland folder of ASIF. I'd really like him to do that ;-)

marcel_g · « **Reply #1582 on:** August 12, 2019, 07:51:15 AM »

Here are a couple of photos I got while flying over the Arctic, from Toronto to Hong Kong on August 1st. (yes, I feel bad about flying due to emissions, but it's not a vacation, we've moved to Jakarta for my wife's work. we will also buy some offsets to try to compensate a bit.)

We were trying to sleep through the 15 hour overnight flight, but I managed to some how wake myself up at the right time to open the window blind and blind myself with the glare.

Again, taken on Aug. 1st, somewhere between Greenland and the North Pole. It seems like a lot of water visible in the leads for this area, even for this time of year. Maybe it's normal recently, but I can't imagine it would've been normal when this area used to be dominated by multiyear ice.

If you want to see the full size images, DM me and I'll email them to you.

It might be, but it also might be the iPhone's automatic HDR function creating some extra contrast. It also might the low level of the sun's angle? I couldn't tell with my own eyes because I'd been sleeping and was pretty much blinded by the ice when I tried to look at it.

Yes, I's amazing how you cannot even trust cameras these days!

marcel_g · « **Reply #1587 on:** August 12, 2019, 11:38:49 AM »

Actually, after looking at the original more closely, that dark colour might be all melt ponds, and a low sun angle on wet snow/ice. I think only the pressure ridges are showing up white here, maybe because they stick up into the sunlight?

I've attached a crop of the original to try to show some of the detail.

Edit: in any case, there is no way a Russian research team is setting up a research station on that ice! Yikes.

Shared Humanity · « **Reply #1588 on:** August 13, 2019, 02:10:06 AM »

If those aren't melt ponds, perhaps some frozen over, I don't know what they are and they are everywhere.

I was randomly looking at some landscape in the CAA in the Sentinel-hub and found this in the North of Devon Island (exact position can be seen in the bottom right of the picture). Unfortunately I didn't find the name of this glacier.

What are my eyes seeing here? Did the glacier carve a tunnel through the mountain or are those two completely seperate glaciers?

petm · « **Reply #1593 on:** August 15, 2019, 11:11:49 PM »

Nice image.

To me it looks like it's the start of the stream now draining the glacier. (Well, to be more accurate, the start is actually under the ice, out of sight.) So, it's a low point that has melted down to bedrock, leaving the small glacier to the right, which must be on higher ground, orphaned.

Spoil sport, Espen! It looked like the glacier went through a tunnel (until you provided more data)!
(As a student of geology, I didn't suspect it was, but it's fun thinking of the possibility!)

pearscot · « **Reply #1597 on:** August 15, 2019, 11:36:35 PM »

I can't be sure, but to my eye it appears as though there is a very seep mountain between those two glaciers...I want to investigate on my own now.
