Explore a world never seen before - a world hidden under miles of water, the landscape of the ocean bed. Combining the latest scientific data with state of the art CGI computer hardware we reveal some of the world's sunken mysteries. The Titanic, a WWII sunken battleship and the mysterious Flight 19 lost in the Bermuda Triangle. Using already aired episodes of Drain the Ocean we will be able to highlight each of these sunken treasures and tell their stories.

Drain Alcatraz uses cutting edge visual effects to 'drain' the waters around the notorious island of Alcatraz. With the waters drained away the secrets of Alcatraz are revealed, including exactly why the island's infamous prison was so inescapable.
