Three-quarters of Earth is an alien world, lying beneath the surface of the oceans. And although it encompasses over half of the world’s species, we know more about the surface of Mars than the bottom of the ocean. It’s only recently that science has penetrated this world, revealing extraordinary life forms and vast sweeping landscapes on a scale that defies imagination.

If we could remove the water, what would we see? Using CGI animation, based on the latest scientific research, Drain the Ocean explores one of Earth’s last great frontiers as never before—revealing unimaginable landscapes more dramatic than anything on dry land.

Bonus Program: Into the Abyss (50 minutes).
