The Census of Marine Life is the most comprehensive inventory of the oceans ever undertaken and draws on the work of 2,000 scientists from 90 countries. It will transform how we see the ocean, giving us a better picture of what lives there, our impact and what the future holds. In this film, Horizon reveals the techniques, meets the scientists and explores some of the findings from this massive project.
