Dive to the Edge of Creation
One-and-a-half miles down in the Pacific Ocean, sea-floor chimneys spew clouds of molten minerals. Extraordinary creatures cluster around warm-water vents - the most startling marine discovery in more than 100 years!
In this programme, scientists explore the inner world of the ocean with their submersible Alvin and a revolutionary colour television camera which probes the hot fissures in the earth's crust. For the first time, man observes how mineral deposits are created, and sees a profusion of life-worms 12 feet long, giant clams, sightless crabs.
How can such large creatures survive in perpetual darkness? How many more vents await discovery in the ocean abyss?
