One Ocean

One Ocean begins Thursday, March 4 at 8 p.m. (8:30 NT) on CBC Television

The world’s oceans—which cover 70 per cent of the planet and in fact are all interconnected—are the subject of a provocative new four-part series on THE NATURE OF THINGS with David Suzuki. Starting Thursday, March 4, ONE OCEAN explores how the waters that surround us hold the very key to all life within their silent and shadowy depths. Each breathtaking episode brings to life a vast, interconnected ecosystem: from the diversity and significance of microscopic plankton, to the sleek power of the ocean’s top predators.

A new multi-faceted interactive website,, will launch at the same time, designed to educate and entertain audiences of all ages about the wonders of the ocean and the challenges we all face in protecting it. On the site, Canadians can take the  One Ocean Pledge, an open call to all of us to make a difference in the future life of the ocean. For this campaign CBC has partnered with the Canadian Wildlife Federation, David Suzuki Foundation and Living Ocean Society to promote the message of ocean sustainability. Canadians can spread the word virally of One Ocean Pledge through Facebook.

Revealing the ocean’s awesome beauty, extraordinary power and beguiling mysteries, ONE OCEAN’s HD cameras bear witness to extraordinary and unique events and species, in some cases never before seen in this way. Viewers will get to see underwater volcanoes erupting only metres away from the camera lens and the discovery of rare and bizarre life forms.

ONE OCEAN’s camera teams travelled to Australia, New Zealand, Africa, the Middle East, Europe and the United States and Canada with research expeditions to document their work and discoveries. Guiding us on this adventure are some of the planet’s most innovative and charismatic marine scientists. They reveal new things about the past and present of the ocean the life forces it contains and supports, while racing against the clock to save its future.

The premiere episode, Birth of an Ocean, airing Thursday, March 4 at 8 p.m. (8:30 NT) on CBC-TV, travels back 4 billion years to when there was no ocean. Without the ocean, life as we know it would not exist. From a blistering volcano in Ethiopia, to strange, ancient rock-like structures in Australia, experts trace the evolution of our planet’s greatest asset and the extraordinary evolution of life within it. Learn why one remarkable creature, the nautilus, has survived for more than 500 million years and how nearly 99.9 per cent of species that ever lived on this planet are now extinct. We also meet Tiktaalik (the “fish-a-pod”) believed to be the missing link between the ocean and all limbed creatures, including us.

The second episode, Footprints in the Sand, airing Thursday, March 11 at 8 p.m. (8:30 NT) on CBC-TV, looks at our coastlines and how all of us are inextricably linked to the ocean’s rhythms, whether we live next to it or thousands of kilometres inland. From over-fishing, to the over-development of the world’s coastlines, and the pollution that we keep pouring into the sea this episode reveals how our actions are changing the ocean’s rhythms, to the detriment of life within them. But even as dead zones are increasing, elsewhere there is hope. In Zanzibar locals are taking charge and in New Zealand, we discover ocean areas that are now protected from over-fishing have experienced an extraordinary turn-around – where once sea urchins had taken over and destroyed the reefs and kelp forests. Now their predators have returned and the stunning reef has been restored to its full glory.

Mysteries of the Deep, airing Thursday, March 18 at 8 p.m. (8:30 NT) on CBC-TV, starts in the deepest part of the ocean known to humans and takes us to a secret and magical world far, far beneath the water’s surface. Here, for the first time in human history, technology lets us explore the darkness and crushing pressure of the deep seas and reveals a world of mystery and surprise: mountains higher than Everest, more volcanoes than anywhere on land, and abysses so deep, no human has seen them.  Toxic thermal vents spew hot lava, but life continues to flourish beside them in these unfathomable places. We encounter bizarre eyeless creatures that use bioluminescenceto communicate in their dark world. What is down here? How does it exist? And what don’t we know? Scientists, now modern day explorers, are in a race to answer these questions before our recklessness destroys the undiscovered wonders of the deepest sea.

The final episode, The Changing Sea, airing Thursday, March 25 at 8 p.m. (8:30 NT) on CBC-TV, explores some of the most stunning underwater locations in the world as we set sail on a race to discover the fate of the global ocean. We journey from the majestic kelp forests of Monterey Bay to a magical night on a coral reef and from the storm-tossed waters of the mighty North Pacific to the crystal blue Mediterranean. Over the past 200 years, human beings have poured more than 2 trillion tonnes of carbon dioxide into the atmosphere, and this is not just changing the climate on land, our vast ocean is changing as well. Is mass extinction the inevitable fate of the future sea? In the waters near a still-active Mediterranean volcano, the concluding episode of this stunning and timely documentary series shows us what the future ocean may look like, if we don’t take action now. allows you to enter the ocean and experience it in a very personal way.  Inside the 3D Biosphere users can create their own personal marine reserve. They can challenge themselves on a Mystery Mission, or set a record in the fast-paced Pollution Collector. Visitors can also develop strategies for sustainable fishing and defend coral reefs from the hazards threatening them. Ocean Explorer takes users on guided tours, or allows them to explore independently using Google Earth’s satellite and sonar imagery. Historical timelines, profiles of sea life, experts, and creators of the series and website are available, along with new webisodes and podcasts.
