Under the Pole S01E05 - Deep Sea Corals of Polynesia

Join the U.T.P. team and head to the Polynesian Islands of the South Pacific as they lead an international scientific team to unveil one of the world's least-known ecosystems: the coral reefs of the deep. After setting new records in deep-sea diving within Arctic waters, Ghislain and Emmanuelle Bardout will study how these reefs function, with the hope of capturing on film the corals spawning.
