Giant Pacific octopuses are mystical creatures. A film team managed to gain insight into the mysterious life of these relatives of snails and mussels. It formed a close bond with the elusive squid while diving in the fjords of the Northeastern United States. In parallel, the dive team followed the evolution of the giant octopus Eleonora at Port Townsend Aquarium.

With the help of diver and biologist Laurent Ballesta, a scientific expedition explores three sunken Italian volcanic sites in the Mediterranean.

A peculiar personal journey along the shores of the Mediterranean Sea, the inland sea that bathes the beaches of three continents, passing through the port of Marseille, the Rock of Gibraltar, Algeria and Syria; an artistic and experimental collage made up of thoughts, memories and emotions.

A commercial diver is stranded on the seabed with only five minutes of oxygen supply, but with no chance of rescue for more than 30 minutes. With access to amazing archival footage, this is the true story of one man’s impossible fight for survival.

Adventurer, filmmaker, inventor, author, unlikely celebrity and conservationist: For over four decades, Jacques-Yves Cousteau and his explorations under the ocean became synonymous with a love of science and the natural world. As he learned to protect the environment, he brought the whole world with him, sounding alarms more than 50 years ago about the warming seas and our planet’s vulnerability. In BECOMING COUSTEAU, from National Geographic Documentary Films, two-time Academy Award®-nominated filmmaker Liz Garbus takes an inside look at Cousteau and his life, his iconic films and inventions, and the experiences that made him the 20th century’s most unique and renowned environmental voice — and the man who inspired generations to protect the Earth.

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.

Described as being a film about determination, danger and the ocean’s greatest depths, James Cameron's "Deepsea Challenge 3D" tells the story of Cameron’s journey to fulfill his boyhood dream of becoming an explorer. The movie offers a unique insight into Cameron's world as he makes that dream reality – and makes history – by becoming the first person to travel solo to the deepest point on the planet.

A deep sea submersible pilot revisits his past fears in the Mariana Trench, and accidentally unleashes the seventy foot ancestor of the Great White Shark believed to be extinct.

James Cameron teams up with NASA scientists to explore the Mid-Ocean Ridge, a submerged chain of mountains that band the Earth and are home to some of the planet's most unique life forms.

The film offers several variants of growing up at the Mediterranean coast.

Explore the mysterious giant rings of the Mediterranean, buried at a depth of 120m, with the world-famous Laurent Ballesta, world-renowned diver and his team, to understand the origin of these unique and unknown formations.

Deep sea: 1000m below the surface no light, immense pressure and icy temperatures. The deep sea encompasses more than 90% of the planets habitat. Yet we know less about these depths than about the moon. This film documents the technical, scientific, and ecological challenges of deep sea researchers. Scientists work worldwide together to collect data on the physical state of the upper ocean. With more than 3000 autonomous floats they monitor the oceans for influences on weather systems like El Nino or the monsoon. Does it affect global climate change? Does the deep sea offer solutions for the CO2 issue? Researchers in the Okinawa Trough are trying to find out. The sea floor harbors enormous amounts of resources: oil, natural gas, methane. Scientists work hard to try and locate these materials. Millions of deep sea dwellers are waiting for their discovery. The Census of Marine Life is trying to catalogue these bizarre ocean creatures before they disappear.

Peter Snow presents highlights from today's three deep-sea dives around the world. In 2002 BBC organized three concurrent dives , first in Monterey Bay where unmanned submersible is lowered into underwater canyon which is over mile deep. Second dive is in Grand Cayman where submersible Atlantis will explore life at the spectacular Cayman Wall , Kate Humble reports . During the dive, the crew used bait to attract a deep-water giant, the six-gill shark. Third dive takes place in middle of the Atlantic 1200 miles west of Portugal, which is also deepest of the three dives, divers will descent in Russian submersible Mir from research vessel Keldish and the Mir will dive in the bottom of the ocean in 2300 metres .

The Stella Maris Berria is a tuna vessel destined for scrapping. However, Iñigo Mijangos and Iñigo Gutierrez, two members of the NGO Salvamento Marítimo Humanitario, have an unusual idea: to transform the fishing boat into a rescue boat to save refugees drowning in the Mediterranean Sea. That is how Aita Mari was born.
