This exhaustive overview of oceanography captures the excitement of discovery in the making. The Oceans opens up the world of ocean science to the general reader and raises significant questions about the future of the ancient, nurturing ocean itself.The oceans cover more than 70 percent of the globe, yet less than 5 percent of that expanse has been explored. But, as Drs. Prager and Earle show in this vivid survey of ocean research, our knowledge is suddenly accelerating: various dives, soundings, computer analyses, and other probes are uncovering amazing facts about the 142 million square miles beneath the seas.
