I saw some footage on the BBC over the weekend showing the are around the Larsen Ice Shelf and I was stuck by how perfectly sheered many of the ice bergs in the area were. They looked like precision cuts, perfectly flat, they looked like blocks. I have not seen this before. Is there an explanation to this phenomenon of near perfect cleaving?
Also are there implications for the glacier(s) that feed this ice shelf after this part of the shelf breaks off?
