At the center of Deep Blue Homea penetrating exploration of the ocean as single vast current and of the creatures dependent on itis Whittys description of the three-dimensional ocean river, far more powerful than the Nile or the Amazon, encircling the globe. Its a watery force connected to the earths climate control and so to the eventual fate of the human race. Whittys thirty-year career as a documentary filmmaker and diver has given her sustained access to the scientists dedicated to the study of an astonishing range of ocean life, from the physiology of extremophile life forms to the strategies of nesting seabirds to the ecology of whale falls (what happens upon the death of a behemoth). No stranger to extreme adventure, Whitty travels the oceanside and underwater world from the Sea of Cortez to Newfoundland to Antarctica. In the Galapagos, in one of the books most haunting encounters, she realizes: I am about to learn the answer to my long-standing question about what would happen to a person in the water if a whale sounded directly alongsidewould she, like a person afloat beside a sinking ship, be dragged under too? This book provides extraordinary armchair entree to gripping adventure, cutting-edge science, and an intimate understanding of our deep blue home.
