Antarctica / Re: PIG has calved

A (maybe silly) question concerning the absence of melt ponds on PIIS-MIS
Not an expert, but I did notice that many of the melt ponds were near (or at least below) exposed rock which may be absorbing more sunlight and causing the melting.

Another possibility is that the glacier thins as it approaches the calving front so the upper surface must be sloped down towards the water so any melt might run off.

The Wikipedia link Tor provided is very informative, and I found the criticism section quite useful.

Agreed. ASLR's posts around Antarctica was the reason I started reading here in late 2013. I don't follow the political threads. All the best whatever you decide ASLR.

Here is a wider view of the Brunt Ice Shelf showing the other side of the Halloween Crack.  Looks like there is a chance for a significant  calving there.
