Over 100 years ago, working in water depths greater than 100 meters, was inconceivable, possible only in the fiction novels of the time. The literary classic, 20,000 Leagues Under the Sea, written by Jules Verne in 1870, described a mysterious “sea monster”— a submarine that travels to the deepest parts of the world’s oceans. This is an impressive accomplishment, even by today’s standards!
