Deep Blue is a major documentary feature film shot by the BBC Natural History Unit. An epic cinematic rollercoaster ride for all ages, Deep Blue uses amazing footage to tell us the story of our oceans and the life they support.

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.

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.

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.

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.

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.

For eight centuries, between the 9th and 1st century BC, the Etruscans, inhabitants of the Italian peninsula, were one of the most powerful peoples of the Mediterranean basin, and when they disappeared they left behind impressive necropolises, vestiges of sanctuaries and even entire cities. How did they attain such power? How far did they extend their dominion and influence? What were the causes of their decline?

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 .

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.
