Oceans – The Great Southern Ocean

Today on Discovery Enterprise we present the second episode of the BBC documentary Oceans and explore the Southern Ocean which girdles the ice covered of Antarctica.


In the year 2000, the International Hydrographic Organization created the fifth and newest world ocean – the Southern Ocean – from the southern portions of the Atlantic Ocean, Indian Ocean, and Pacific Ocean. The new Southern Ocean completely surrounds Antarctica. The Southern Ocean extends from the coast of Antarctica north to 60 degrees south latitude. The Southern Ocean is now the fourth largest of the world’s five oceans (after the Pacific Ocean, Atlantic Ocean, and Indian Ocean, but larger than the Arctic Ocean).

The Southern Ocean, which circles the globe without being blocked by land, is home to the Antarctic Circumpolar Current (ACC), the longest of the world’s ocean currents. Also known as the “channel”, it connects the Indian, Atlantic and Pacific Ocean basins and exerts a powerful influence over the Earth’s climate. The ACC carries 150 times more water around Antarctica than the flow of all the world’s rivers combined.
The team investigates why parts of the Southern Ocean are warming twice as fast as the rest of the world’s oceans and looks at the impact of this phenomenon.

Expedition leader Paul Rose, environmentalist Philippe Cousteau Jr, maritime archaeologist Dr Lucy Blue and marine biologist and oceanographer Tooni Mahto brave some of the roughest seas and the strongest winds on the planet. They go in search of one of the planet’s most curious and enigmatic creatures – the weedy sea dragon. They explore iconic kelp forests to investigate how they’re being threatened by the rise in sea temperatures and a new predator. They dive one of the thousand shipwrecks in these waters and in a unique sunken valley, they search for mysterious deep ocean creatures normally found hundreds of metres below the surface. And they enter a maze of perilous sea caves to hunt for evidence of ancient sea creatures that can reveal how this ocean formed.
