At the top of our planet lies the Arctic Ocean - a shape-shifting world of ice and water, home to unique animals like polar bears, harp seals and bowhead whales.

Frozen South takes us to the most hostile ice world of all – Antarctica, an entire continent covered in snow and ice full of surprises. Here hardy animals cling around its coastal fringes.

Frozen Lands takes us back to the far North of the planet where we enter the largest land-habitat on Earth, home to great Boreal forests and the barren tundra. This vast wilderness is governed by its seasonal extremes.
