The Restless Sea: Exploring the World Beneath the Waves - Hardcover

Part of Kunzig's purpose in writing the book is to highlight how little we actually know about the sea, especially now that we have the power to permanently damage it. We've got a lot to learn yet, but we've come a long way from the early oceanographers who had very little data to help them map the seafloor: "To say that they relied heavily on intuition in sketching the seafloor is to engage in euphemism: they made most of it up."

But the unknown represents opportunity and excitement for scientists. Kunzig clearly captures the thrill of discovery that makes otherwise sane people jump on boats and head out beyond sight of land, risking seasickness, numbing cold, and even death. Here he captures the moment when scientists realized for the first time that life existed down to the very bottom of the sea:

From the 150 pounds of grey, chalky mud, he and his collaborators sifted five species of mollusk, two species of echinoderm, an annelid worm or two, a sponge, numerous single-cell foraminiferans, and more.... Now the deep sea was, once and for all, alive; and the idea of an azoic zone anywhere on Earth's surface should have been dead, once and for all.

Kunzig's tour of the world's oceans and the scientists who study them is full of the joy of discovery. The Restless Sea makes you understand why a couple of echinoderms might be cause for a party. --Therese Littleton
