Just curious if large ice shelves like this ever start to separate and end up refreezing before they actually break. Looking at the diagram in the article leads me to think that this part of the ice shelf is a goner, but I don't actually know that much about the environment in or near Antarctica.

It's unlikely in this case, but it has happened in some other areas. The Brunt Ice Shelf (where the British Halley VI station is located) is largely made of reconstituted icebergs like you describe.

Of course, that shelf is also having some crack problems: https://www.theguardian.com/world/2016/dec/07/british-antarc...
