Overview

We know less about the deep floor of the ocean than the surface of the moon, yet many think it has the potential to power our planet and cure disease. Take a journey to one of our planet's final frontiers - the deep ocean trenches - to investigate the effects of intense pressure on life forms that exist under extreme conditions. Discover how life on earth may have even begun in mysterious "black smokers" on the ocean floor, and explore how what happens at these depths impacts our planet.
