Pulitzer Prize winner William J. Broad takes us on an adventure to the planet's last and most exotic frontier -- the depths of the sea. <I>The Universe Below</I> examines how we are illuminating its dark recesses as a wave of advanced technology quietly opens the Earth's largest and most mysterious environment. <P>Broad takes us on breathtaking dives and expeditions -- to the Azores, to the <I>Titanic</I>, 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. <P><I>The Universe Below</I> is an unforgettable trip to our last great unexplored frontier.
