Explore a world never seen before - a world hidden under miles of water, the landscape of the Atlantic sea bed. What do we really know about this more than 41 million square miles of open ocean, and why is it's floor covered with wrecks? Are there strange, supernatural forces or deadly forces of mother nature at work here? And can science help explain the reasons behind the large number of sunken ships and aircrafts? Join expeditions to dive long-lost vessels, and follow the scientists who are probing the darkest and deepest corners of this underwater world. We make use of the latest technology and sonar data to "drain" the Bermuda Triangle, and long lost vessels scatted across the Atlantic sea floor. Computer generated, three-dimensional maps will offer the first glimpse of these mysteries.
