A scientific film that puts you in a good mood, instills hope, intelligence and beauty. It’s tonight Tuesday April 12, 2022 on France 2, at 10:55 p.m. (and then available in replay for a month). The documentary Sentinels of the Mediterranean does not mask the ills that weigh down the future of the big blue, but focuses on the scientists, NGOs, citizens and companies who are struggling to find solutions. With concrete promises to the key. “The Mediterranean is attacked from everywhere, we see the sum of everything that should not be done”, testifies the navigator Isabelle Autissier. But the semi-enclosed sea also captures a human, creative and protective energy, which suggests much better days.
Tomorrow, ships will be able to avoid collision with cetaceans
Maritime traffic is responsible for the death of 8 to 40 fin whales each year in the only Pelagos sanctuary, yet created 20 years ago between Var, Sardinia and Italy to protect marine mammals? Denis Ody, head of the “cetaceans” program at WWF and his team, as well as Thomas Folegot of Quiet Oceans are refining the development of animal tracking systems by triangulation, so that boats can avoid them. A tool could be available within five years for ships, if the public authorities agree to finance its development.

Bluefin tuna, with such juicy flesh, are threatened by overfishing? The Ifremer specialists, who have already managed to stabilize the stocks a few years ago, continue their tracking by plane, feed an artificial intelligence to help count the schools, explains Tristan Rouyer. With the help of wholesale fishermen, they place high-tech beacons on these tireless swimmers, whose tracing reveals that they can travel 10,000 km per year. Enough to negotiate quotas as accurately as possible and preserve the species.
New plastics to replace those that pollute marine life and humans
Were plastic microparticles found in the human placenta? Anne Leila Meistertzheim, from Plastic@sea and Jean-François Ghiglione, from the CNRS, are testing all kinds of plastics in sea cages to see which ones are most likely to develop pathogens on the surface. The Managing Director of the lighters category at Bic, François Clément Grancourt, thus understood thanks to their work that it was necessary to remove the yellow color from its products, which are curiously more harmful. And since the equivalent of 600 containers is dumped every day in the Mediterranean, other work aims to develop new plastics, without petroleum and devoid of toxicity, based on algae, wood, cellulose which will degrade at the speed wet paper.
CO2 contributes to the acidification of water? Corings have shown that it is necessary to concentrate protection efforts on the Posidonia meadows, “which capture 15 times more carbon dioxide than a tropical forest per unit area”, explains Nuria Marba, from the Mediterranean Institute for Advanced Studies, which runs a monitoring network. Replanting programs are now mobilizing many young divers, while NGOs are calling for a ban everywhere in the Mediterranean – as is already the case in France – the wild anchoring of boaters, who tear off the precious carbon gluttons. An application is being developed to help boats avoid anchoring where they serve as fish shelters.
We would not want to deflower the subject any further, which is still interested in the monk seals of Greece as well as the pink flamingos of the Camargue. This film, written and directed by the great reporter Elena Sender, former collaborator of Science and Futureand Alexis Barbier-Bouvet, is part of a documentary series created by Frédéric Fougea.
