Gombessa Expedition 4 Laurent Ballesta went to observe a gathering of thousands of groupers during the full moon of June 2014 (Le mystère mérou) in the southern pass of the Polynesian atoll of Fakarava, where he discovered a pack of over seven hundred grey sharks. How can this unprecedented density be explained? Could it be that social behaviors govern this wild horde? During three years of preparation, he and the other divers on his international scientific team tamed their fear by abandoning the defensive reflexes that provoke shark aggression, with the aim of slipping into the heart of the raging pack to study and film it from the inside. Sharks fitted with microchips, receiving antennas, hydrophones, an ark of 32 synchronized cameras...: a whole technological arsenal is mobilized for the project. As the groupers approach for their annual spawning, what battle plan will the sharks deploy?

Threatened by the guns of Southern Africa's farmers, black-backed jackals have found shelter in a new but arid area, Namibia's Skeleton Coast.

The "gravity" nightmare is becoming a reality: tons of rocket and satellite parts have been scattered into space over the past 60 years. The fragments collide with other objects, producing more and more scrap - a proliferation that has long since gotten out of control and poses an acute danger to rocket launches and space stations.

A journey in the footsteps of the birds and marine mammals of the French Southern and Antarctic Lands: the populations of the islands on the edge of the Southern Ocean subject to strange fluctuations, closely studied by researchers. In the isolated archipelagos of Crozet and Kerguelen, king penguins, albatrosses, and petrels face winds and storms every year to breed. Elephant seals, fur seals and orcas also live there. But some populations are declining, sometimes abruptly and unexplained. For over sixty years, scientists have been trying to unravel this mystery through their observations and increasingly sophisticated technologies. Their discoveries reveal astonishing behaviors and the threats facing these survivors of the extreme south. A journey into the heart of the wind and waves, where science and exploration intertwine to tell the story of these extraordinary birds and marine mammals.
