Blue Planet Live
Ep. 3/4 -

We think of our planet having many different oceans; but it is in fact just one. What happens in one corner can affect life in another.
As marine life around the world is poised to embark on epic journeys across the planet, the Blue Planet Live team discover how ocean traffic, over-fishing and noise pollution could impact these sea-faring commuters.
Steve Backshall, Chris Packham and Liz Bonnin will be rolling up their sleeves along with the scientists, to further understand the importance of migrations, long and short, and understand how human demands on the oceans have made an impact on these wild journeys.
Liz joins scientists on the Great Barrier Reef to witness baby turtles taking their first steps, and carries out a live weigh in on young shearwater chicks.
Over in the Bahamas, Steve prepares for the most challenging dive of the week. To understand more about sharks and the journey that they will make when they leave the Bahamas, he has his most dramatic underwater encounter yet with a live dive among hammerheads, and goes on a shark run with scientists as they count one of the biggest gatherings on the planet. Over in Mexico’s Seat of Cortez, Chris hooks up with whale experts in search for the return of a long-lost visitor to these waters, the sperm whale.
Live cameras will be standing by on research vessel Atlantis in the Pacific, as deep-sub Alvin resurfaces with some vital signs from the abyss.
