Frozen Ocean

David Attenborough narrates a glimpse of the wildlife of the Arctic Ocean, as spring begins after four months of winter darkness. Polar bears lead their cubs to hunt, beluga whales trapped by ice see the possibility of escape, harp seals teach their pups to swim, and bowhead whales come in search of food. Plus, a look at how the region is warming faster than anywhere else on Earth due to climate change.
