Episode 1: The Blue Planet
The oceans dominate the world's weather systems, and support an enormous variety of life, from the largest animal that has ever lived on Earth, the blue whale, to the tiniest plankton.
Episode 2: The Deep
Since 1979 when they were first able to explore the deeper regions of the ocean a new species has been discovered on average every ten days!
Episode 3: Open Oceans
Sardines feature in more than one episode and it certainly makes me think they probably feel quite at home in a can! They pack together in the oceans swimming in vast numbers forming into a giant ball.
Episode 4: Frozen Seas
There is lovely film of Belugas arriving with their young and we see the mothers swimming with their babies on their backs.Polar bears seals and arctic foxes.
Episode 5: Seasonal Seas
This episode includes amazing shots of various jellyfish some of them huge and although they may look beautiful in their way they are deadly hunters. We see the common jellyfish gather in packs.
Episode 6: Coral Seas
This programme focuses on the amazingly fragile ecosystems which have grown up around the world's coral reefs. The reefs take hundreds of years to develop from tiny larvae, and are adorned with spectacularly colourful life.
Episode 7: Tidal Seas
As well as the moon gravitational pull causing the tides the River Amazon in Brazil is on certain days affected by the pull of the sun too. This creates a tidal bore where a tidal wave moves about two hundred miles inland, pretty impressive.
Episode 8: Coast
Where land meets sea nothing stands still, and the challenge is to live with the constant change. For this reason many animals at the coast do not hang around for too long, and there are some strange visitors.
