World Without Sun (1964)

Shark expert Neil Hammerschlag and a crew of researchers search for an elusive hammerhead shark.

Documentary exploring the hundreds of species of life that thrive in total darkness at the hydrothermal vents along the Mid-Ocean Ridge, several miles below the ocean surface. Little food filters down from the surface and there is no sunlight to support photosynthesis.

A film by John Ernest Williamson

Grey Fear follows a close group of pro-surfers searching for an adventure off the beaten track as they fly into a cluster of islands in the south pacific. There they discover a secluded break and once in the water several great white sharks that begin to ravage through the stranded group. Now they must endure unimaginable horror in an epic battle to survive if they are to even make it out of the water alive."

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.

After an earthquake destroys their underwater station, six researchers must navigate two miles along the dangerous, unknown depths of the ocean floor to make it to safety in a race against time.

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.

Exploring an unknown world 10,000 m beneath the waves. After capturing a giant squid on film, NHK's deep-sea film crew explores our planet's deepest point The Mariana Trench is nearly 7 miles deep. The water pressure is immense, and it's a world that's long been out of our reach. What creatures could survive such hostile conditions? This is an expedition to explore the earth's deepest frontier. Narrated By David Attenborough.

Cuba's enforced isolation has resulted in the unlikeliest of marine reserves: a huge, rambling archipelago known as Jardines de la Reina, or "Gardens of the Queen." Stretching around 140 miles along the southern coast of Cuba, it's one of the longest barrier reef systems in the world. Get an up-close look at Fidel Castro's diving playground, a forgotten ocean paradise unseen for half a century, and witness exotic species rarely seen elsewhere in the region. It's the lost jewel of the Caribbean, but how long can this pristine wilderness survive?

This is a documentary about the fragile and complex marine ecosystem in the Bay of Fundy. The film traces relationships within the food chain - from tiny plankton to birds and seals and finally to whales and humans. The film is a plea for careful management of our ocean resource and was first telecast as part of CBC's Nature of Things series.

Acid Horizon follows marine ecologist Dr. Erik Cordes on a harrowing deep-sea expedition to track down the "supercoral", a strain of the deep-water coral Lophelia pertusa that seems to possess the unique genetic capability to thrive in a low-pH ocean.

Jacques Cousteau's 1942 plunge into the Mediterranean sea

Defense forces launch two new weapons, the giant tank Kamikaze and the drill tank Gokumei, to meet the the monster invasion head on. But as the beasts work their way to Tokyo, will they be enough to stop the monsters from laying waste to the city?

An expedition looks into whether Titanic's hull had a construction design flaw that caused her to break apart. Featuring advanced CGI technology, archive documents and photographs, as well as footage from the modern-day History(R) expeditions, "Titanic's Achilles Heel" is a remarkable journey into the ongoing legacy of a ship that continues to capture the world's attention.

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 Mediterranean. Because people have been travelling there for thousands of years, it is believed to be without secrets. And yet, far below its surface, lie vast unexplored territories, luxurious gardens worthy of the finest tropical coral reefs. These natural wonders are inaccessible to the traditional diver, in a twilight zone, between 60 and 120 m, where there’s less than 1% of sunlight. If diving at such depths is always a challenge, staying there is a fantasy, a utopia that becomes reality in Planet Mediterranean. In the tradition of Commander Cousteau and his "houses under the sea," the team of diver-photographer Laurent Ballesta is undertaking a new world-record setting mission in complete freedom and without time limit.

After years of swimming every day in the freezing ocean at the tip of Africa, Craig Foster meets an unlikely teacher: a young octopus who displays remarkable curiosity. Visiting her den and tracking her movements for months on end he eventually wins the animal’s trust and they develop a never-before-seen bond between human and wild animal.

The story of a girl who encounters a unique life journey, seeking and searching in the mysterious underwater world.
