The ocean covers 70% of the surface of the planet. It redistributes heat from the tropics to the temperate and polar regions driving our weather and climate. It provides around half of the oxygen we breath and absorbs around half of our CO2 emissions, slowing global warming.

But how will it change as we move into a warmer future?

We start in the 7th Century AD with the Venerable Bede wondering along the Northumbrian coastline, pondering the harmony of the moon and seas, and gradually work through the centuries piecing together natures clues to build up an understanding of how the ocean 'works' and how it might look in the future.
