National Geographic: Drain the Ocean

Three-quarters of Earth is an alien world, lying beneath the surface of the oceans. And although it's home to over half of the world's species, we know less about the bottom of our own planet's ocean than we do the surface of Mars. If we could remove the water, what would we see? Using CGI animation and the latest scientific research, Drain The Ocean does just that, allowing viewers to explore one of Earth's last great frontiers as never before, and revealing extraordinary life forms and vast sweeping landscapes on a scale that defies imagination.
