Royal Institution Christmas Lectures 2020: Planet Earth – A User’s Guide Episode 2 of 3

Dr Helen Czerski unpicks the ocean’s heating and plumbing systems, showing how whale poo, waterfalls beneath the sea and zooplankton are all vital parts of an engine that distributes heat and nutrients around our planet.

Helen voyages from the cities of the ocean to its deserts, from its deepest depths to its surface, via an alien inner structure that is home to so much of the Earth’s life. This planetary life support system plays a critical role in generating weather, providing food and connecting trade routes. The ocean is an underappreciated resource. Helen tells us what we need to know to be good citizens of an ocean planet.
