Broad takes us on breathtaking dives and expeditions -- to the Azores, to the Titanic, to hot springs teeming with bizarre life, to icy fissures aswarm with gulper eels, vampire squids, and gelatinous beasts longer than a city bus. We meet legendary explorers and researchers and go with them as they probe the ancient mysteries of a universe that encompasses the vast majority of the Earth's habitable space and holds millions of humanity's lost artworks and treasures.

The Universe Below is an unforgettable trip to our last great unexplored frontier.

Many people realize that the ocean covers some two-thirds of the earth's surface (the actual figure is 71 percent). But as William J. Broad points out in his entrancing The Universe Below, this hardly tells the story of the sea's dominance of our planet. The world's oceans are more than two miles deep on average and, contrary to long-held views, are richly populated with life all the way to the bottom. So, in fact, the sea probably makes up something like 97 percent of all inhabited space on Earth--we surface dwellers are almost an afterthought.

"This book is about the largest unexplored part of our planet, the deep sea," writes Broad in his prologue, "and how we are illuminating its dark recesses in a rush of discovery that is shattering old myths, rescuing lost treasures, and laying bare secrets of nature hidden since the beginning of geologic time." In seven chapters, each devoted to a different aspect of deep exploration and discovery, Broad weaves together scrupulous reporting and scientific explication (he has won two Pulitzers for his science writing for the New York Times) along with history and his own personal experiences, all told in vigorous, intelligent prose that often rises to a quiet poetry. The result is one of the most enthralling science books of the decade. --Nicholas H. Allison
