The Deep (1997)
At a depth of one mile, the deep sea begins. Making up more than 50% of the Earth’s surface, it is the largest unexplored part of our planet. Until very recently man knew more about the solar system than about the universe beneath the waves. Now this is about to change. Scientists are illuminating the deep in a rush of discovery that is scattering old myths, and laying bare secrets of nature hidden since the beginning of geological time.
