Nat Geo Live: Ocean Soul With Brian Skerry

National Geographic photographer Brian Skerry has spent more than 10,000 hours underwater, often in extreme conditions beneath Arctic ice and in predator-infested waters. Journey with him from the North Atlantic, where harp seals face the threat of declining sea ice, to the temperate waters of New Zealand, home of the fastest shark in the world—the mako. The stunning images he captures while on assignment offer a mesmerizing glimpse of the “soul of the sea.”
