Oceans

Although Western civilization developed around the shores of the Mediterranean Sea, human activity is threatening to destroy it. Under cover of night the team dives into the treacherous Straits of Messina, where they hope to find and film one of the largest predatory sharks in the world, the increasingly threatened six-gill shark.

The Indian Ocean is the third largest of the world’s major oceans, covering over 72 million square kilometers – almost 15% of the Earth’s surface. With some of the most remarkable marine habitats in the world, it is also surrounded by many of the world’s most populous nations. With shark fishing increasing at an alarming rate, the team visits a small community in Mozambique to uncover what is driving the trade.

In one of the most dangerous dives of the series, the team enters a black hole to discover what our oceans would have looked like 350 billion years ago, when they were little more than toxic soup. The expedition later investigates the oldest living evidence of life on Earth, dives into shark-infested waters to test shark-repellent and uncovers how the Atlantic has been invaded by a poisonous alien fish.

Travelling over 965 kilometers through the waters of Djibouti, Eritrea and Sudan, this expedition to the Southern Red Sea is a voyage through remote and untouched areas. It’s a rare chance for the team to explore places where only a handful of scientists have been, and unmapped places that have never been filmed before.

Storm-force westerly winds, huge seas, vast expanses of sea-ice and mountainous icebergs are just some of the characteristics depicting the notoriously hostile Southern Ocean. Often described as the lung of the planet, the Southern Ocean plays a vital role in regulating levels of carbon dioxide in our atmosphere – but parts of it are warming twice as fast as the rest of the world’s oceans. The team investigates what impact this is having.

Rich with life, over one third of the Earth’s marine mammal species are found in the Sea of Cortez, alongside more than 800 species of fish. With these waters in a constant state of flux, learn how the very forces that created the sea more than five million years ago will also destroy it and witness up-close, rare behaviour of the hammerhead shark, the humboldt squid and the sperm whale.

There are 10,000 times more living organisms in the oceans than there are stars in the Universe. Covering over two-thirds of our planet, oceans hold clues to the mysteries of our past and survival of our future. But the secrets of our oceans have remained largely undiscovered…until now! Filmed in stunning High Definition in some of the most beautiful, diverse and threatened seas on our planet, OCEANS premieres exclusively on Discovery HD beginning Sunday, December 6 at 8 p.m. ET. Travelling across the world to the Southern Ocean, the Atlantic, the Indian Ocean, the Red Sea, the Sea of Cortez, the Arctic Ocean and the Mediterranean, this eight-part series ventures into some of the planet’s most challenging environments to build up a timely global picture of our world’s most magnificent – and least understood – vital asset.

Oceans are the blue life-blood of the world, vital for the health of the planet and everything that lives on it. With a mission to uncover the clues to what the world’s oceans used to look like before they were exploited, a team of ocean experts – explorer and expedition leader Paul Rose, maritime archaeologist Dr. Lucy Blue, marine biologist Tooni Mahto and conservationist Philippe Cousteau Jr. (grandson of Jacques Cousteau) – undertake a journey to discover the world beneath the waves.

Venturing fearlessly into some of the planet’s most treacherous habitats, the team descends beneath frozen Arctic ice-sheets and into mysterious black holes of the Bahamas. They dive the tannin-stained waters of the Southern Ocean in search of rarely-seen deep-sea creatures, and into hazardous sea caves to reveal our oceans’ uncharted history.

Using cutting-edge technology, they explore ancient wrecks that tell tales of piracy and go in search of some of the world’s most endangered species. See how remote controlled model helicopters investigate the germs in a whale’s sneeze and dive into unique geological cave formations that reveal the chequered history of one of the planet’s most ancient seas.

From the striking but gentle turquoise seas of the Caribbean to the icy-cold Arctic, the OCEANS team lives together on a dive boat, sharing their achievements and frustrations as they push themselves in search of answers. Our oceans are changing faster than ever and there’s never been a better time than now to explore the last true wilderness on Earth.

The health and thickness of ice cover in the Arctic Ocean is diminishing. The team dives under the ice and takes measurements on top of the ice flow and later sends the results to NASA to help them discover how fast it is changing.
