The Deep: Creatures of the Abyss (1997)
In the depths of the deepest parts of the ocean reside some of the strangest creatures mankind has ever witnessed. As technology improves, we are able to explore deeper, and for longer. The specimens that scientists are collecting are beyond belief.
We travel into this alien realm with the scientists of the Monterrey Bay Aquarium Research Institute. They have unique access to one of the deepest parts of the ocean, the abyssal zone, which is about a mile below the surface. Instead of exploring directly, themselves, they employ they use of a robotically operated vehicle to explore new landscapes and collect specimens.
