The deep sea - which gets darker till no more sunlight penetrates at about a kilometre depth and ever colder closer to the bottom of the ocean - covers most of the planet and is, thus, by far the largest habitat on earth, yet, it has been explored less than space.
The blue whale is a perfect symbol for the oceans, the vast blue expanse that dominates our planet while 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 our Blue Planet.
