Draining the Gulf of Mexico brings deadly secrets back to the surface, proving beyond doubt that the story of North America — through trade, slavery, war, the oil industry and even the death of the dinosaurs — can be understood only by looking deep below the waves.

In ancient times, the Mediterranean was home to some of the greatest civilizations the world has ever seen. Scientific data, combined with computer graphics, can drain the sea to unlock mysteries about the rise and fall of the Minoans, the Greeks, the Carthaginians and the mighty Romans, while unveiling the powerful natural forces at work in this unique region.

For centuries treasure ships plied the oceans of the world, packed with silver, gold and precious stones. Many of them lie undiscovered on the sea floor.

Draining the oceans reveals the richest wrecks ever found.

Exciting evidence emerges of civilizations lost under the waves. But are these ancient cities the long sought-after Atlantis or accidents of geology?

The Pacific Ring of Fire is an underwater hotbed of volcanoes, mega-quakes, and giant tsunamis. Along its edges, 500 million people live in ever-present danger. Combining CGI with cutting-edge ocean-mapping technology, we drain the Pacific Ocean to reveal the deadly geological forces behind Earth's most destructive natural disasters, and uncover catastrophic threats lying just off the coasts of Seattle, Tokyo, and New Zealand.

The Nile was once home to the ancient Egyptians, one of the greatest civilizations on Earth. Scientific data, combined with computer graphics, drain the Nile's waters — and surrounding sand — to reveal a lost wonder of the ancient world, monumental fortresses, and the origins of ancient Egyptians' obsession with the afterlife.

The China seas are the most fiercely contested and mysterious waters on the planet. We expose the remains of the biggest battleship ever put on the water - the Yamato - and uncover other treasures and mysteries from past centuries.

The Battle of Jutland was the most violent sea battle in history, fought in 1916 between the British and German fleets. After a day of carnage, both sides claimed victory. But who really won? Maritime archaeologists and historians drain the North Sea to investigate the most devastating battleships of WWI and find out what happened to them once the firing was over. Also examined is the scuttling of the German fleet at Scapa Flow.

Where is Malaysian Airlines flight MH370? CGI reconstruction and unprecedented access to key personnel in sea floor searches reveal the challenges of locating aircraft that go missing in the deep ocean. How did MH370 crash without a trace and why has modern technology failed to pinpoint the wreckage? Drain the Oceans goes inside the longest, most expensive search in commercial aviation history.
