Undersea Exploration - Paperback

by John Lockyer (Author)

The ocean we know the one we swim, fish and play in is very different from the deep water far from land. The deep ocean has no light, and the water pressure is so great it can shatter human bones! But that hasnt stopped explorers and inventors developing and improving underwater machines and equipment that have eventually taken people to the deepest places on Earth. Why? To see whats there, of course.
