The world’s oceans covers almost 2/3 of our planet. Right beneath the surface starts a fascinating world of sounds, the habitat of whales, the biggest mammals on our planet. Some of them are singing; others are clicking essential sounds to communicate.
Tracking Their Silent Voices is the story of a scientific dream and a personal quest. The quest of passionate marine biologist O. Boisseau. Onboard a 21 meters research vessel, especially equipped, he needs 7 months of effort, adventurous lifestyle and scientific intuition to fulfil his dream: finding and analyzing one of the least explored species of the world - beaked whales. On a small research sailing boat he will make it.
Scientists believe there are at least 20 different beaked whale species. That is one fourth of all known whale species. Some species of beaked whale we haven't even seen alive so we know them from dead specimen, and genetic analysis.
As whales spend 80 to 90% of their life below the surface we can’t see them, so we can’t study them with visual techniques. Boisseau believes that acoustics gives us a special, unique, window on the undersea world: by using acoustic techniques only, he will break new ground in gently exploring and protecting the highly endangered beaked whales, that are like many other whale species threatened from extinction.
