Voyage across the oceans with one of National Geographic?s most seasoned photographers and discover a vast, hidden world beneath the waves. Using his camera to communicate, Brian Skerry has spent more than 10,000 hours underwater telling the oceans? stories. His images celebrate the mystery of the depths and offer portraits of creatures so intimate they sometimes appear to have been shot in a studio. Skerry dives eight months of the year, often in extreme conditions beneath Arctic ice or in predator-infested waters, and has even lived at the bottom of the sea to get close to his subjects.
