Jellyfish blooms are making headlines around the world. This is due to the damage they cause to tourism, fishing and our health. How can these creatures, which are over 98% water and have no shell, skeleton or brain, expand so rapidly? Although this is a normal stage in the life cycle of these gelatinous animals, we have to admit that blooms have become much more frequent and massive in recent decades. We're even witnessing jellyfish populations appearing in more and more regions where fish have been replaced by them, such as off the coast of Namibia, in the Black Sea, in the Sea of Japan and in certain areas of the Baltic Sea. What causes this? Why has the role of jellyfish in the ocean been underestimated, even though they outlived the dinosaurs? Are jellyfish on their way to dominating the oceans as they once did? What if they were to be the only ones left?

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.

Bright Green Lies investigates the change in focus of the mainstream environmental movement, from its original concern with protecting nature, to its current obsession with powering an unsustainable way of life. The film exposes the lies behind the notion that solar, wind, hydro, biomass, or green consumerism will save the planet. Tackling the most pressing issues of our time will require us to look beyond the mainstream technological solutions and ask deeper questions about what needs to change.

This films reveals the extraordinary variety of life found in the vast blue expanses of the open ocean. Here, all the action takes place in a 10 metre deep band of water, just under the surface. Many species use this section of water to migrate and hunt while others use ingenious ways to stay hidden where there appears to be no shelter.

Groundbreaking documentary which follows a Japanese-led team of scientists as they attempt to shed light on the mysterious world of deep sea sharks. Only 50 specimens of the newly discovered 'megamouth' have ever been sighted. Over four years, scientists and film crews voyaged in midget submarines into the depths of Suruga Bay and Sagami Bay to film them. Prehistoric 'living fossil' sharks such as bluntnose sixgill sharks, goblin sharks and frilled sharks also lurk in the depths. As part of the investigation, a sperm whale carcass was placed at the bottom of the sea to attract these sharks, which were then studied and observed from the submersible vessels. Revealing in detail the previously unknown behaviour of deep sea sharks, the film unravels another of the intriguing mysteries of our planet's biodiversity.

This is the planet we still know so little. We call it Earth but less than 1/3 is land, over 2/3 is water and we use that water as a dumping site for our waste and as if it's an inexhaustible "horn of plenty" for humans. Our most important ecosystem is on the verge of collapse unless we act now. At this very moment the main problem with the oceans is that they're getting emptier and emptier. If we don't do anything then we face one of the biggest disasters in history of mankind.

There is a mystery there and the answer lies somewhere between Bermuda, Puerto Rico and Miami. Hundreds of boats and planes have disappeared in the ocean with little or no trace at all. Most of these cases can be explained quite easily by human error or bad weather. But there are some that defy all explanation. Theories abound on these causes: Aliens, massive gas eruptions and freak waves. The documentary reveals that the boats and planes face a real danger in a triangle, but the true threat is often as strange as the wildest theory.
