In this talk at London’s Royal Institution Helen dives deep into the depths of the Earth's oceans and illuminates the engine that powers them all - the energy from sunlight.

Discover the rich diversity of life and movement in our oceans, from ancient navigators to permanent residents of the deep. Explore the vast currents, invisible ocean walls, and underwater waterfalls that shape our oceans' complex systems. Understanding the workings of the global ocean system is essential now that it is under significant threat, so we must put this knowledge to use in order to save our blue machine.

Copies of Helen's latest book 'Blue Machine: How the Ocean Shapes our World' are available to purchase after the talk.
