BBC Frozen Planet II

THIS IS OUR FROZEN PLANET: EACH YEAR, FOR MONTHS AT A TIME, MORE THAN A FIFTH OF OUR WORLD IS FROZEN SOLID.
In this sparkling kingdom you'll meet mind-blowing animals who survive bitter snowstorms, towering icebergs and frozen seas. Dive under the ice to swim with seal pups, meet a Greenland shark who is easily 250 years old, and spot a snoozing windy walrus. Watch orcas sneak up on whales as they relax in the spa, and hold your breath as wolves play a deadly game of hide-and-seek in a frozen forest.
Discover the gripping stories from the new BBC TV series narrated by Sir David Atten:borough.
