... Introduction As a result of the last few years having witnessed the rapid growth in popularity of a variety of underwater vehicles, it might well appear to the uninitiated that there may be a day, not far distant from now, when the diver might-be replaced completely. It is my view that those...

Until now more than 40 divers have been exposed to depths of 400 msw or deeper during the French deep diving experiments. During the Atlantis...
