The Blue Planet

The blue whale is a perfect symbol for the oceans: the vast blue expanse that dominates our planet whilst still remaining largely unexplored and mysterious. Yet the oceans are an integral part of our lives. Their influence dominates the world's weather systems. They support an enormous range of life, from the largest whales to the smallest plankton, from hordes of sea birds to lonely, deep-sea fish. All this is governed by a complex system of biological and physical forces. This first episode demonstrates the sheer scale, power and complexity of the 'Blue Planet'.

Seasonal Seas

Shafts of sunlight radiate through a green sea. This blazing light is the vital source of energy used by the countless billions of plankton which grow every spring and summer in the world's temperate sea, the richest of all habitats. Forests of giant kelp, the fastest growing plant in the world, harbor thousands of animals. Sharks move in to pick off the vulnerable. Sea otters, brilliantly coloured anemones, squid and exquisite leafy dragons are just a few of the other creatures that live in this cool, rich water.

Coral Seas

Bathed in warm, clear tropical water and brilliant sunlight, coral reefs are the rainforests of the sea. Surrounded by ocean deserts they are rich oases of life. Spectacular numbers make it necessary to stand out to survive.This competition is highly visible as brightly coloured fish compete for food, territory and mates. But the corals themselves are also dynamic. Incredible time-lapse photography shows the dramatic formation of a coral reef, portraying its myriad inhabitants and its ultimate destruction.

Tidal Seas

Tides govern marine life. Tidal marshes are one of the most productive parts of the world. Numerous plants support numerous animals, yet life is not easy: predators are attracted to these enormous quantities of food, forcing animals to seek constant protection from attack. Relief comes with the crashing waves, as the tides flow once more. Between the tides, when the sands become depleted of food and air, the worms, clams and shrimps just endure the expected pause.

Coasts

The boundary between land and sea is an exciting place, with animals constantly coming and going. From the open oceans, millions of seabirds are forced to come onto land to breed. Sea eagles steal kittiwake chicks from their nesting ledges. Turtles lay their eggs in the sand and marine mammals haul themselves out to fight on the beaches. Sea-lions emerge from the kelp to give birth, while killer whales come crashing in on the surf to snatch the sealions' young.
