Everyone's favorite deep water submersible (and really, who doesn't have a favorite deep water submersible?) is getting an extensive refit which should allow it to explore more than 90% of the ocean's depths. Alvin's been around a long time, and has done some spectacular science. It's nice to hear it'll be around a good while more. I do, however, find it a little bit strange that the article completely failed to mention the sub is actually owned by the Navy.
