Check out this list of each episode, with a small description for each and air times. All times are ET/PT in the US.
POLE TO POLE
Airs Sunday, March 25, at 8 p.m. ET/PT
PLANET EARTH's premiere episode, "Pole to Pole," ties the series together with a fresh understanding of how life in every nook and cranny of the globe is connected — from the highest mountains and darkest caves; shallowest water and deepest oceans; ice-covered lands and great plains; untamed jungles and giant forests; to freshwater and the harshest deserts. The sunward tilt of Earth's orbit dictates all our lives, creating the seasons that trigger one of the greatest spectacles in the world — the mass migration of animals. It's a unique view of the majesty of our planet and the amazing creatures that live here.
MOUNTAINS
Airs Sunday, March 25, at 9 p.m. ET/PT
This episode tours the mightiest of mountain ranges and introduces a few of its extreme animal mountaineers — the mountain lion, snow leopard and puma, all rarely filmed creatures. CGI time-lapse footage brings the mysterious geological history of mountains to life, while flying alongside bar-headed geese provides a spectacular view of the Himalayas.

DEEP OCEAN
Airs Sunday, March 25, at 10 p.m. ET/PT
The ocean is by far the largest habitat on our planet and it remains almost entirely unexplored. This episode scans the ocean's vast surface and trolls its depths, revealing daytime hunters and night feeders, from dolphins to manta rays, and life among hot vents and underwater massifs, following the energy source between oceanic white tips, myctopids, tuna, whale sharks and petrels.

DESERTS
Airs Sunday, April 1, at 8 p.m. ET/PT
Deserts are united by their lack of rain, yet they are the most varied of our planet's ecosystems. Go where freshwater is really precious and meet animals that have learned to survive with small amounts of it, such as the wild Bactrian camel of Mongolia's Gobi Desert that eats snow instead of drinking water or Chile's guanacos that lick dew from cactus spines. Experience spectacular aerial and time-lapse footage, featuring an explosion of life and shifting sand dunes.

ICE WORLDS
Airs Sunday, April 1, at 9 p.m. ET/PT
This episode guides viewers on a journey to the polar extremes of our planet. Freshwater is frozen and out of reach, and coupled with numbing temperatures, this makes life hard in frozen climes from the top to the bottom of the world. CGI time-lapse and elapsed-time filming techniques show Arctic ice coming and going over the centuries, and emperor penguins settling in to breed in Antarctica.

SHALLOW SEAS
Airs Sunday, April 8, at 8 p.m. ET/PT
Follow a humpback whale mother and her calf on their epic journey to the most prolific feeding grounds that fringe the coasts. The shallow seas that lie above the continental shelf are the richest in the ocean. It is here that you find the coral reefs and, in colder waters, the fishing grounds. Massive shoals of fish act like magnets for predators. Spectacular storm footage, above and below the water, reveals extraordinary events in this tropical paradise.
