Two biologists set out on an undertaking as colossal as their subjects—deciphering the complex communication of whales. Dr. Michelle Fournet and Dr. Ellen Garland journey to opposite hemispheres to uncover a culture eons older than our own.

The documentary follows leaders and community members from the tropical Pacific island nation who are making bold changes to move the needle on marine protection. With a population of under 2,000 people and a marine reserve covering 40% of its waters, Niue has demonstrated the ways in which traditional knowledge and contemporary science can live in harmony for the benefit of people and the planet.

A marine biologist and a government agent investigate mysterious deaths and rumors of a sea monster in a secluded ocean cove, and find themselves involved with a marine biology professor conducting secretive experiments, international spies trying to steal his secrets, a radioactive light on the sea bottom, and the malevolent thing which guards it.

Blue Whales: Return of the Giants 3D takes viewers on a journey of a lifetime to explore the world of the magnificent blue whale, a species rebounding from the brink of extinction. Following two scientific expeditions—one to find a missing population of blues off the exotic Seychelles Islands, the other to chronicle whale families in Mexico’s stunning Gulf of California—the film is an inspirational story that transforms our understanding of the largest animal ever to have lived.

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?

In French Polynesia, there is a place where every year, thousands of groupers gather in secret followed by hundreds of sharks… The photographer, diver and biologist Laurent Ballesta, with his team, wanted to better understand what motivates these fish to wait until the exact day of the full moon to spawn all at once! With the help of researchers from the CNRS of Moorea, they dived and conducted numerous experiments to study and witness this unique phenomenon. Taking advantage of this period of incredible richness, Laurent Ballesta did a record dive of 24 hours at over 20 meters.

On his ship "Calypso," as well as in a submarine, Jacques Cousteau and his crew sail from South America and travel to Antarctica. They explore islands, reefs, icebergs, fossils, active volcanic craters, and creatures of the ocean never before seen. This voyage took place in 1975, and Captain Cousteau became one of the first explorers ever to dive beneath the waters of the frozen South Pole.

The endless expanses of the Indian Ocean are home to the last natural paradises: Remote atolls surrounded by coral reefs in crystal clear water.

Whole regions of this ocean are still unexplored, many reefs are not marked on any map. The departure of the research vessel Agulhas II from the island of La Réunion marks the beginning of one of the greatest scientific adventures of our time. The expedition, initiated by Monaco Explorations with the support of the Prince Albert II of Monaco Foundation, lasted six weeks and led into the Western Indian Ocean along the Mascarene Plateau.

Originally, in 2014, Laurent Ballesta had just one precise objective: to unravel the mystery of groupers. To understand the issues involved in their collective reproduction. But although focused on the study of groupers, the real surprise came from the sharks. Never before had the team been confronted with such a density of grey reef sharks. The divers took up the challenge of counting them. Methodically, they repeated the operation many times to arrive at the impressive figure of 700 grey reef sharks.

Each year, the team returned to the southern pass of Fakarava in French Polynesia. Until 2019, for the fourth expedition, "Gombessa 4" is the synthesis of precise and unique scientific protocols. The mission demonstrated that shark hunts are not anarchic, but rely in part on social organization within the horde, following in the footsteps of the 700 grey sharks in "700 sharks in the night (Gombessa 4, Genesis)".
