Antarctica / Re: Pine Island Glacier (PIG) Calving and Discussion

The quality is very poor, but I have the impression that the blocs from the SIS are getting loose.
Not sure due to the image quality, but also a feeling that the Crescent is moving, along with more melange.

But even if we get this extra cooling only at mid latitude that extra heat so generated will have to go somewhere, I would expect some movement northwards that would bring this melting force to the Arctic

In the mean time, a new calving occurred on the NIS

I do not know where to post this, but Wilkins ice sheet is showing signs of getting a drumming short term and there is on top of that that eastern crack inland that could expand quite quickly in my mind....

On top of Baking's remarks, we can note on the eastern side many small cracks (inside the "square"
Besides, the main (putative) iceberg has fractured a lot, its lifetime after the calving might be quite reduced as a consequence
On the crack on the SW tributary is far more apparent than on previous images : is it an effect of the post treatment on an aggravation ?

The cracks appear to extend parallel to the sea front :
link with the side completed for some time already
tentative small cracks linking the two big EW cracks - maybe visual artifacts ?
extension of the cracks link to the NS opening at the middle of the shelf
doubling of the length of the southern crack

All evolutions I spotted are underlined in the image

A minor calving at the junction between PIG and SW tributary.
Tha cracks in the SW Tributary seem to have widened at htat point too

Good image from Worldview today
New cracks on the eastern side (circled)
And I have the impression that the big central cracked have lengthened (see the white lines). Or is it just a visual artifact ?

Apparently new cracks appeared recently on the shelf, a big chunk seems ready to get loose.

Further movement : dislocation of the main iceberg going on the east side, and rotation of the whole, opening the front to more open seas.

Many changes in that area in the past few days.
Here are 3 successive screen shots from Sentinel :
* loss of the iceberg on the east side that were in advance to the main big new iceberg
* on the west side, tremendous outbound movement of the icebergs floating in front of the SW tributary, with additional calving
* movement of the main iceberg towards the exterior

Another calving in preparation ?
A big central crack appears to be opening, quite visible on this sharp image :
