In a special edition of Naked Oceans we celebrate the world's first Census of Marine Life as it draws to a climax this month after ten years of amazing ocean discoveries. Recorded at the Census conference at the Royal Institution in London on October 4th 2010, we meet many of the people behind the census, find out how the whole grand project got going, and pick out some of the census highlights. We also hear some musical inspiration from the census and chat with distinguished oceans explorer, Sylvia Earle.
