Naked Oceans, from the Naked Scientists

In the concluding installment of our two-part season finale of Naked Oceans, we get a bit thoughtful and contemplate what might lie in store for the future of the oceans. Helen catches up with some of the marine experts we've heard from throughout the last two series and asks them about what they think the future might hold. Are they ocean optimists or pessimists? What solutions will be needed to protect the oceans of the future? And on a more positive note, we ponder what great ocean discoveries might lie ahead.

The history of life in the oceans spans over 3.5 billion years. In this Naked Oceans we'll take a whistlestop tour of that story...

Why is it sometimes such a big deal when species end up in the wrong places? On Naked Oceans this month we explore marine invasions and find out how people shift species around the oceans, what problems this causes, and what can be done to stop them. We visit the Caribbean to get the lowdown on a notorious ocean alien, the lionfish, and find out how the best policy could be Eat 'em to beat 'em. Janet Voight tells us about her recent report that warns deepsea explorers to be very careful not to pick up any unwanted hitchhikers. And in Critter of the Month we ask Miriam Goldstein to tell us if she were a marine species, which would she be and why.

Is ambergris whale vomit or whale poo? We find out in Naked Oceans this month as we dive into ocean treasures, old and new. Last month we explored some of the ways we pollute the oceans by using them as a dumping ground for too much rubbish. And in this episode we look at the variety of things we've taken out of the ocean, from prized perfumes to inspiration for new medicines. Christopher Kemp tells us all about the mysterious stuff, ambergris - the subject of his new book. And at Scripps Institute of Oceanography, we call in on some researchers who are putting glowing critters to good use. And in Critter of the Month, Emmett Duffy tell us, if he was a marine creature, which one he'd be and why.

Naked Oceans goes from plastics to poo this month, as we get the low down on ocean pollution and find out how the stuff we dump into the seas causes all sorts of problems for the things that live there.

We find out about the best job in the world on Naked Oceans this month as we take a look at what its like to work in the ocean realm. Sarah chats with a host of marine scientists who work in one of the top spots in the world for ocean research. We hear from someone who as well as doing his own science is using cutting edge communication tools to inspire the next generation of marine scientists and conservationists in two very different parts of the planet. And in Critter of the Month we meet a playful denizen of British waters that like nothing more than messing about with human scuba divers.
