Drain The Oceans: Deep Dive

Experts use cutting-edge technology to drain the sites of lost civilisations as they investigate the powerful forces that caused these cities to vanish beneath the waves.

For centuries treasure ships sailed the oceans of the world packed with silver, gold and precious stones. Around the world, countless treasures and wrecks remain unexplored.

Under the seas lives a lost graveyard of sunken war ships. Countless vessels from WWI and WWII pepper the seafloor. Among those, some of the most powerful weapons ever built.

Extreme weather patterns have threatened ships and mariners for centuries. The perfect storm, towering walls of water, powerful winds and churning seas can overwhelm any ship.

The act of sabotage is one of the most effective weapons in any arsenal. Direct attacks, advanced weaponry and the element of surprise have sent many ships to their final resting place on the seafloor.

War, weather and human error have led to some of the worst maritime disasters in US history. But imagine if we could empty the oceans, letting the water drain away to reveal these secrets.

Deep below the ocean lies a tectonic monster. The seafloor is the world's biggest tsunami machine and its dangers have remained hidden from view.

Beneath the waters of the world, lies undersea empires and relics of their bloody wars. Through the use of cutting edge technology we will uncover lost empires for the first time.
