Martin Clunes: Man to Manta

160 km southwest of Reunion Island, just a few dozen metres beneath the surface of the Indian Ocean, lies the peak of an underwater volcanic structure known as Mont La Pérouse. The base of this enigmatic geological formation lies 5000 meters below sea level, with a size comparable to that of Mont Blanc. Permanent currents and strong winds characterise this site in the open seas, culminating in complex diving conditions under which Laurent Ballesta, together with his Gombessa diving team and local researchers had to navigate in order to conduct the study in depth. Further techniques such as observation and photographic inventory, biological and geological sampling, and the use of cameras and sonars were employed in this challenging expedition.

Bacteria, viruses, but also fungi, algae, pollen, and even insects: micro-organisms thrive and circulate constantly in our sky. How can so many living beings find their way into the air and circulate? How do they survive? And what influence do they have on our lives and the living world? Biodiversity, health, climate: it is only recently that scientists have begun to understand how this discreet aerial "plankton" affects our lives and our ecosystem. But despite their many virtues, some of these micro-organisms are now threatened by human activities. With the help of experts and 3D models, this scientific investigation plunges us into the heart of a still mysterious world, and reveals the diversity and fragility of the air we breathe.

A vivid journey into the mysterious subterranean world of mycelium and its fruit— the mushroom. A story that begins 3.5 billion years ago, fungi makes the soil that supports life, connecting vast systems of roots from plants and trees all over the planet, like an underground Internet.

Climate change has reached the indigenous Nenets people in the north of Siberia. The nomads' herds of reindeer move on thin ice. The warming in the Russian Arctic is becoming dramatically visible. Huge craters open in the thawing permafrost and expose dangerous viruses and bacteria. Forest floors dry out and the taiga catches on fire. The pack ice off the coast is melting and depriving polar bears of their habitat so that they approach human settlements in their desperation. The changes in the nature of the Arctic Circle combine with the measurements of researchers and observations of the indigenous people to form a disturbing overall picture: In the Russian Arctic, Pandora's box has been opened! The film team had the chance to shoot in regions that were been restricted areas for decades. The documentary shows in impressive and depressing images already existing effects, phenomena and ominous interlinkages of global warming.

The waters of the North Pacific around Canada's Vancouver Island are a strange and little known world. The water is incredibly clean, the location is isolated and huge thermal vents heat the otherwise cold surrounding these factors combined have led to animals and plants that can grow to huge proportions. Humpback whales, orcas, wolf eels and bald eagles all thrive here. Our team of experts go in search of the elusive Pacific Giant Octopus. Growing up to 7.5 meters across with the power to kill sharks, it is a formidable creature, but also intelligent and incredibly shy. The dive team invites us into an alien world, where persistence is rewarded with encounters with three of these magnificent creatures.
