To celebrate the launch of the brand new Naked Oceans podcast, we venture beneath the waves to investigate the impacts of oil spills on the marine environment. We hunt down the hidden world of microbes in the Louisiana wetlands, trace the fingerprint of oil in the open oceans, and discuss the likely fallout from the Deepwater Horizon oil spill in the Gulf of Mexico. We'll also be exploring the effects of a changing climate on marine habitats, finding out what warmer water means for life at the poles and meeting some of Antarctica's unique marine wildlife. Plus, Carl Safina, President of Blue Ocean Institute explains why he would like to be a Bluefin Tuna!
