The Blue Planet

Go exploring under the ocean thanks to The Blue Planet, a series that travels from various coasts to the poles examining the depths of the water. Although two-thirds of the world's surface is covered with water, scientists know less about the oceans than they do about the surface of the moon, so it's a fascinating place to research and learn more about.

Each episode of the documentary focuses on a different area from the deep ocean to frozen seas, where David Attenborough provides insight into the fascinating creatures who call it home. There's also a sequel to the documentary called Blue Planet II for even more footage.

What the critics say:  UCL PI Media said: "These documentaries do an incredible amount to elevate public interest in the natural world, as well as to raise awareness of our relationship with it. They are a credit to the BBC, and almost worth the TV licence alone; may they continue for many years to come."
