One of the great challenges we face in exploring the oceans is to get close to marine life without disturbing it. Enter freediver Frederic Buyle, whose noiseless diving lets him approach even shy animals. Buyle, who can descend 50 meters on a single breath and stay there for up to four minutes, teams up with underwater cameraman Christian Petron (The Big Blue). Whether in Polynesia, Mexico or the Mediterranean, they work closely with scientists and locals to find answers to the mysteries of our oceans.
