THE FRONTIER BELOW: The Past, Present and Future of Our Quest to Go Deeper Underwater

Humans only reached the deepest ocean floor in the same decade they set foot on the Moon. From the earliest divers to the latest submersibles, this volume chronicles their quest. It explains diving suits and bathyspheres, profiles pioneers, outlines the dangers of the bends, and reveals the opportunities that await below 4,000 meters. 16 pages of photos, some in color.
