Helen is supporting the Chalfont St Giles & Jordans Literary Festival 2024.

Join Helen as she dives deep to illuminate the murky depths of the ocean engine. From the ancient Polynesians, who navigated the Pacific by reading the waves, to permanent residents of the deep such as the Greenland shark that can live for hundreds of years, she explains the vast currents, invisible ocean walls and underwater waterfalls that all have their place in the ocean’s complex, interlinked system.
