1. "The Blue Planet"

Broadcast 12 September 2001, the first episode looks at how ocean life is regulated around the globe by currents and the varying position of the sun. Near a Pacific seamount, there is a large concentration of marine animals because when the current makes contact with the submerged rock, it forces upwards plankton and other organisms. This in turn attracts other fish to the area that are higher up the food chain, like tuna, and those that are higher still, such as silky sharks. Off South Africa, a similar situation occurs every June when sardines migrate and are pursued by a caravan of various predators. The South Atlantic waters are the roughest, and storms also churn up nutrients to the surface. These feeding grounds have led to the world's largest albatross breeding colony, on Steeple Jason Island, west of the Falklands.Phytoplankton forms the basis of all sea life, and every night some 1,000 million tonnes of creatures ascend from the deep to search for food.Lunar phases can also have a bearing on events and the mass arrival of Ridley sea turtles on a Costa Rican beach is shown. Herring initiate the most productive food chain, providing sustenance for humpback whales, and Steller's and California sea lions. In addition, their eggs are nutrition for many, both above and in the sea. Along the coast of California, a migrating gray whale and her calf are targeted by a pod oforcas, who hunt down and kill the calf. Meanwhile another gray whale carcass has sunk to the bottom of the deep sea. Hagfish, a sleeper shark, and other scavengers arrive to feast on the carcass. A year and a half later the carcass is striped to the bone. This episode won anEmmy Award for "Outstanding Cinematography for Non-Fiction Programming". George Fenton's work in this episode won another Emmy for "Outstanding Music Composition for a Series (Dramatic Underscore)".[3] This episode was broadcast in the United States with the title "Ocean World".
