Four extraordinary scientist-aquanauts are racing to transform the ocean into humanity’s next home.

Though Earth is an ocean planet, 95% of it is completely unexplored. While NASA readies for the Moon and Mars, Deep Sea Big Tech dives into Inner Space with never-before-seen access to the Navy researchers, engineers and divers who are pioneering solutions like deep-sea submersibles, liquid breathing and permanent underwater cities. Can we dive deeper than ever before? Can we create a true 'aquatic human'?

Long shrouded in the shadows of military intelligence, uncover the real and ongoing quest to transform mankind into an aquatic species by 2050.
