As I recall, (my one graduate level glaciology class was almost 20 years ago) the first observation of Ice Streams was documented in Antarctica, not Greenland. There are many at the South Pole, and they are not just coastal. (see the link to the Snow and Ice Center, go to the news page, there are a couple of articles there that document ice streams (both active and dormant) using ground pentrating radar).

The same group does monitor the ice shelves that are breaking off. I've links...somewhere...if I find 'em I'll post 'em. There was an intersting case where a very large berg blocked a bay as it was moving along the coast. This cut off the wave action, which allowed the bay to freeze over when it normally wouldn't.
