Wow, those are incredible pictures, especially the ones showing the calved icebergs.

Massive tabular icebergs. You cannot get a sense of scale from the satellite pictures. The photos are awesome!

Here is another present from Linette Boisvert and her colleagues at the NASA Operation IceBridge, it is a video showing the fligth from where the images (above) ended:

At the risk of looking a gift horse in the mouth, where can we find links to higher resolution versions?

And again all credits to Linette Boisvert and the NASA Ice Bridge Team here is a row of photos from Nioghalvfjerdsfjorden where Lambert Land is seen from the northside :

Breaking News
I have been waiting for this to happen for a while, but via other sources I can now see the calving session is underway, this calving session could well be the largest calving session since Zachariae Isstrøm was separated from the former tongue in 2012, it could be larger than the well known calving session at Jakobshavn Isbræ in August 14 - 16 2015. My prelimerary estimates is it could be up to 13 km2.

The animation below show: The potential calving area is marked with red color. And the animation in the black box show the calving event at Jakobshavn Isbræ August 14 - 16 2015 (same scale).

You need to click on the image to animate and enlarge!

Thanks for this information  - the first breaking news since I visit this forum.
Let's look which part will break down and whether this will be one big simple event or a row of consecutive smaller calvings. Any guess when it will happen?

Hello Stephan the reason I call it a session, is to avoid some clever persons arguing about the size of the calving, because most calvings or 99,9...% is more than just one action it is a series of actions. It will for sure be a large calving, how large we will see? The calving session as I see it has allready started.

Zachariae Isstrøm - Here is animation showing the massive retreat over the years at this impressive glacier:
Beware this animation is very large you need to click on the image to animate and enlarge!!

Amazing, the cracks of today's calving front already existed in 1999.  :o

No not really, the reason is I made the 1999 material slightly transparent :)

Yeah, I thought it was transparency. But the 3 melt lakes in the upper left were in exact same location 20 years ago. It's the underlying topography of course, but still notable.

And notice the sea ice outside the island barrier in 1999, 3 years later in 2002 all the sea ice broke up including the Zach Bay area, letting a lot of debris out of the bay trap, probably one big reason for the retreat and different calving activity at Zachariae Isstrøm later, the backpressure was not there anymore.

LOL that makes sense. I was wondering how it could survive so long. Thanks for clarification, Espen.

With all that warm water underneath, how long into the fall/winter can we expect this to continue??  Can this break to the first grounding line in the near future?  Isn't that a  somewhat scary eventuality?
