"Approaching this vast and multifaceted subject with profound passion and a refreshing approach, ocean scientist and diver Ellen Prager, along with internationally renowned underwater explorer Sylvia Earle, crafts a comprehensive and understandable survey of the ocean's past, present, and future. Leading readers on a fantastic undersea voyage spanning 4.5 billion years of natural history - from the Precambrian through the present - The Oceans reveals the nature and science of everything from waves, tides and sea level change, to hurricanes, El Nino, and global warming, along with marine sediments, plate tectonics, and the astonishing myriad of life that populates the ocean. In a discussion of the very latest discoveries in marine science - a field that combines oceanography, biology, geology, chemistry, physics, meteorology, and trailblazing underwater exploration - we are led into the interworkings of the sea and the increasingly complex relationship between humans and the ocean."--BOOK JACKET.
