At the heart of Unknown South America

Computer-generated imagery and other visualization techniques reveal how it would look if all the water was removed from RMS Titanic's final resting place.

Antarctica: A Frozen History takes a look at the history and stories of the human explorations in the Antarctic. Although quite slow paced and relatively old, the documentary film successfully incorporates reconstructed film material and original Antarctic expedition footage to fully illustrate the hardships of the heroic and extreme arctic explorations. Human endurance is tested to the maximum, as the documentary takes a look back at those who have tried, failed and conquered this most unforgiving landscape. Some of these stories entail Robert Falcon Scott, a Royal Navy officer and explorer who led two expeditions to the Antarctic regions: the Discovery expedition of 1901–1904 and the ill-fated Terra Nova expedition of 1910–1913. Scott reached the South Pole in January 1912 only to find he had been beaten to the spot by 33 days. His entire party died on the return journey; eight months later, a search party discovered some of their bodies, diaries and photographs.

Extreme der Tiefsee - Abysses

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.

A riveting story of polar exploration that investigates the motivation, psychology, science, and physical endurance that have characterized the historic heroes who have explored the frozen continent of Antarctica over the last 200 years.

Deep in the jungle of Central Vietnam, lies a magnificent underground kingdom. Hang Son Doong which translates as “mountain river cave”, is the largest cave passage in the world and a place of spectacular beauty. With more people having climbed Everest than visited Son Doong, its pristine charm has remained undisturbed for millions of years. In 2014, Son Doong’s future was thrown into doubt when plans were announced to build a cable car into the cave. With many arguing that this would destroy its delicate eco-system and the local community divided over the benefits this development would bring, the film follows those caught up in the unfolding events. Beautifully shot and scored, “A Crack In The Mountain” is a powerful exposé about how both good and bad intentions can ultimately lead to one of the world’s greatest natural wonders being trampled for money. As well as inspire those who care about our natural heritage to fight to protect it.

Documentary correlating contemporary archaeological discoveries in the Far North with the descriptions of Viking explorations and settlements detailed in the Icelandic sagas, suggesting a pattern of exploration and trading that extended over the circumpolar region for thousands of years before Columbus' celebrated voyage.

Gombessa Expedition 3 Protected by an international treaty Antarctica has been spared the effects of hunting and fishing. But signs in ice’s cyclical patterns and its biodiversity have become worrying. Connected to the planet’s global ecosystem via atmospheric circulation and ocean currents, this white haven is suffering the effects of human activities. To document and explain what is unfolding in Antarctica, photographer, diver, and marine biologist Laurent Ballesta and photographer of extreme environments Vincent Munier will be blending their artistic perspectives of a rapidly changing continent. Laurent will tackle technical and human prowess below the ice to bear witness to its remarkable underwater life. His photographs will advance knowledge on Antarctica’s unique and little-known biodiversity. On land, his eye riveted to the lens of his camera, Vincent captures snapshots of life in an Emperor Penguin colony.

The New Horizons team examines the latest findings and imagery from Pluto and the fringes of our solar system revealing a world unlike any other we've seen before.

The Sealab project, launched in 1969 off the shore of northern California, was the brainchild of a country doctor turned naval pioneer who dreamed of pushing the limits of ocean exploration like NASA did space exploration. The massive, 300-ton tubular structure was a pressurized underwater habitat, complete with science labs and living quarters for divers who would live and work there on the ocean floor for days or even months at a time. During the height of the Space Race, this daring program also tested the limits of human endurance and revolutionized the way humans explore the ocean.

In the new film "Undercity: Las Vegas," urban historian Steve Duncan and director Andrew Wonder head below Sin City to see what lurks beneath the surface of one of America's most bustling cities.

Dr. Mark Fairchild, world-renowned archaeologist, traces the hidden years of Saint Paul's life in the mountainous Turkish countryside of Rough Cilicia.

Did Cartier dream of making a country from this land of a million birds? In his records of his exploration he certainly marvelled at seeing the great auks that have since disappeared from Isle aux Ouaiseaulx, the razor-bills and gannets that are gone from Blanc-Sablon, and the kittiwakes from Anticosti, all the winged creatures of all the islands which he described as being "as full of birds as a meadow is of grass". And that's not even counting the countless snow geese.

The story of the 1914-1916 Antarctic exploration mission of Sir Ernest Shackleton.

A documentary re-telling of the remarkable and dangerous journey taken by President Theodore Roosevelt and legendary Brazilian explorer Cândido Rondon into the heart of the South American rainforest to chart an unexplored tributary of the Amazon.

An exploration of Rodez Cathedral and its stained glass windows: praying figures and scientific imagery. A study on color, repetition and flickering consisting of 292 photographs.

Best friends Hazel Findlay and Maddy Cope journey to the rocky outer reaches of Mongolia, on a quixotic search for new trad routes.

Explorer Thor Heyerdahl and his ten-man crew sailed their reed boat, the Tigris, over routes he believes were followed by Sumerian traders 5,000 years ago. The film goes beyond science to focus on the man, Heyerdahl, in an effort to explain what motivates him to risk his life in the search for knowledge.

For six weeks we explored the Antarctic Peninsula by sea kayak, sailboat, foot and small plane, observing the fast changing evolution of this most remote place. Impacted by climate change - temperatures have warmed along the Peninsula faster than anywhere on the planet during the past 50 years - this part of Antarctica is also experiencing a boom in tourism and nations fighting over who owns what as its ice slowly disappears. This National Geographic-sponsored exploration is a one-of-a-kind look at Antarctica from a unique perspective - sea level.
