MegaStructures is a documentary television series appearing on the National Geographic Channel and Five in the United Kingdom and on France 5 in France.
Each episode is an educational look of varying depth into the construction, operation, and staffing of various structures or construction projects, but not ordinary construction products.
Generally containing interviews with designers and project managers, it presents the problems this involved the or products that are now in general use within the construction industry.
MegaStructures focuses on constructions that are extreme; in the sense that they are the biggest, tallest, longest, or deepest in the world. Alternatively, a project may appear if it had an element of novelty or are a world first (such as Dubai's Palm Islands). This type of project is known as a Megaproject.
The series follows similar subjects as the History Channel's Modern Marvels and Discovery Channel's Extreme Engineering covering areas of architecture, transport, construction and manufacturing.

Oceans cover two thirds of our planet. These five massive bodies of water create the largest eco system on the planet. The Pacific, Atlantic, Indian, Arctic and Antarctic Oceans contain some of the most dangerous animals on earth. Unique and venomous creatures hunt in tropical waters, while powerful carnivores rule the icy Antarctic. Ideally suited for survival in their ocean environments, twelve elite creatures stand above the pack, armed with keen intellect, ingenious camouflage, venomous fangs and bone-crushing jaws. Whether hunting or defending, their hardcore weaponry should be avoided at all costs! Dive into their world to experience their full, lethal potential – and see what happens if we get in their way. They're elusive, powerful and they're dangerous. They are the Oceans Deadly Dozen.

In a remote corner of the South Pacific, National Geographic Explorer Enric Sala – one of the world’s leading marine ecologists – leads an elite team into an isolated underwater Eden. Sharks reign in the southern Line Islands, where humans rarely visit and survival is still of the fittest. Completing a daring survey of life on the reef from the micro to the mega, the research team uncovers secrets in what could be the last unspoiled archipelago on Earth.

Where do the seas come from? How did marine creatures evolve? We’re in the front row when scientists solve these and many more mysteries about the past, present and future of the world’s oceans. The program advances new theories about the origin of the oceans and reveals the profound effects that ocean life will have on our own species in the future. By combining natural history, history and science, and through a judicious use of CGI, the film sketches a never-before-seen picture of the oceans.

He discovered the Titanic, the Bismarck, and dozens of other lost wrecks like the Lusitania and JFK's PT-109. He helped prove the theory of plate tectonics, unearthed newfound forms of life at hydrothermal vents, pioneered the use of deep-diving submersibles, and remotely operated vehicles for undersea exploration. The legendary explorer of Titanic and Lusitania looks back on his life behind his famous exploits and unveils a major new discovery on the occasion of the 35th anniversary of the Titanic find.

How did life begin? its one of the most fundamental and difficult questions that has challenged us for ages. Our planet is teaming with life, from the highest mountain to the deepest ocean; life is everywhere. But what was the firing pistol that started the evolutionary race? How did material go from non-living to alive?
