Looking back a year - at my pet glacier - It has been a quite year at Zachariae Isstrøm compared to the last 5 years, maybe because of all the attention this impressive glacier received suddenly both here and in the scientific world, who knows (John "Bonzo" Bonham could not cope with it either)?
In the animation below:
A It is where you find the most important changes, the calving front is retreating and you will find cracks beyond it.
B The  general calving front is more or less the same, but future calves are seen further behind the front.
Kap Zach is being further sharpened
Have a ice day!

I may add that thinning of the ice sheet behind Zachariae Isstrøm is a reason for the "break" in the retreat and speed of the glacier?
Have a ice day!

Espen thank you for the animation. I have been wondering about calving front advance/retreat.
In the stupid questions department, can yo post the link you use for these hi-res sat images? I know for certain I used to have it bookmarked but it somehow disappeared and I cannot recall what it was. Thanks.

What happened during the dark season in 16 Sentinel 1 images.

That is so cool, Wipneus!
The things I wondered about after looking not too deeply at 6-month old and current images are made crystal clear.
Arctic ice is healthy for children and other living things.
