Watch One Ocean online: Episode 1 The Birth of an Ocean

In The Birth of an Ocean we travel back to ancient time, telling the story of the ocean’s turbulent beginnings, and its successive incarnations. It’s a journey that introduces the enormity of the ocean over space and time – at four billion years old the ocean is nearly as old as the planet itself. In a remote part of Western Australia, we venture to the stunning, crystal blue waters that harbour the descendants of the first life on earth. These formations once covered the ancient seabed, and today they give scientists a remarkable window back in time. Traveling forward, we discover that almost 99.9% of species that ever lived on this planet are now extinct. On the lush and diverse Osprey Reef, we swim alongside scientists to learn why one remarkable creature – the nautilus – has survived, for millions of years, what countless other species could not. In The Birth of an Ocean we trace our own profound connections to the ocean with Tiktaalik , the “fish-a-pod” that scientists believe is the missing link between the ocean and all limbed creatures, including us.
