That's really cool. My long ago ex-gf's brother-in-law (with whom we lived briefly) was a Marine Geologist who worked for a company that made software for undersea exploration. I believe it was his group that discovered the Titanic; at least he was one of the first people to explore it. I was so surprised when I saw him interviewed during a show on the Discovery channel. I can only imagine how cool it would be to explore something like that.
