Underwater Computer For Ocean Research

Jafa writes "Following the article on space laptops, here's an article on a computer built for underwater. Not as in a typical dive computer, or for higher pressure air environments, but wet and under pressure. The article is fairly short on technical details, but it sounds like it uses key chords in place of a typical keyboard. We've got space, underwater, and nano. What other frontiers or environments are left for computers to work in?"
