The oceans are almost as ancient as the planet itself – unchanged for billions of years. Yet oceans are also the planet's great unknown – their greatest depths have been visited less times than the surface of the moon.

Via the Amazon and the Mediterranean, this programme looks at how oceans can die and how new ones are born – and how the oceans helped to cause the greatest mass extinction in Earth's history, belching poisonous gas into the atmosphere and killing almost every living thing on the planet.
