The Eternal Darkness. A Personal History of Deep-Sea Exploration PDF

Until a few decades ago, the ocean depths were almost as mysterious and inaccessible as outer space. Oceans cover two-thirds of the earths surface with an average depth of more than two miles-yet humans had never ventured more than a few hundred feet below the waves. One of the great scientific and archaeological feats of our time has been finally to cast light on the eternal darkness of the deep sea. This is the story of that achievement, told by the man who has done more than any other to make it possible: Robert Ballard.Ballard discovered the wreck of the Titanic. He led the teams that discovered hydrothermal vents and black smokers-cracks in the ocean floor where springs of superheated water support some of the strangest life-forms on the planet. He was a diver on the team that explored the mid-Atlantic ridge for the first time, confirming the theory of plate tectonics. Today, he is exploring the ancient trade routes of the world in hopes of launching a new field of research in deepwater archaeology. In this book, he combines science, history, spectacular illustrations, and firsthand stories from his own expeditions in a uniquely personal account of how twentieth-century explorers have pushed back the frontiers
