A large claving session happened at Helheim Gletscher between March 26 and April 7 2016
Notice the large tabular "cubes":

Pretty good size calving recently, but flipping back through the images, it looks mostly like a conveyor belt.

Helheim Gletscher update:

Large calving observed at Helheim between December 29 2016 and January 4 2017.
At the same time we are into record retreat terratory.

How does the location of the terminus compares to past summer and previous years ?

Thanks for the update Espen.

Where would we be without Espen?  I'm repeatedly grateful for you presence on these threads.

This calving broke up any consolidation/freezing-together of the debris (ice melange) floating in the fjord, so there isn't much winter left to form much of a buttress.  Given how active this glacier is, though, I'm not sure any buttress has been much of a deterrent to calving.  (From what I've read elsewhere, there appears to be different opinions as to how effective sea ice buttressing is for Greenland's glaciers.)
Arctic ice is healthy for children and other living things.

Helheim Gletscher update:

As you can see in the animation below, Helheim Gletscher is calving and retreating into new record lows:
Have a ice day!

Here's an interesting look (from 2008, I believe) at a bit more history here.  A good bit of advance and retreat since 1933. If I'm seeing the picture here correctly, the June 15th terminus appears quite similar to that in 2005.

Heavy calving activity at Helheim Gletscher, and the glacier is now in a record retreat mode:

As I noted above - curious that the terminus is back top approx where it was in 2005.

Thanks for that image. My eyes tell me that the glacier has now retreated beyond the 2005 line.

Perhaps - perhaps not. Insignificant, in any event.  Study the other dates, on the graphic, for more eye work.

Besides - generally speaking, why would not one expect that the general trend would be downward, during  hundreds of years of GW? One knows that in the 350-450 yrs preceding that, the general trend was going the other way.

So why are you not expecting the trend to be downward ie thinner glacier and thinner glacier meaning less friction resistance so that the glacier can advance further until a point when it gets too thin and then starts an unstable retreat?

I'd expect, that in start's and stops (as for the past century) I'd expect pretty much that to be the case, as long as GT's remain at the current level. Don't really need any additional GW, as we're warmer now than 150-200 yrs ago.  Not to sure what the 'unstable' implies -- Earth's climate doesn't invite long term stability; never has.
