For all of human history, the deep ocean has been a source of wonder & terror, an unknown realm that evoked a singular, compelling question: What’s down there?

She takes us on a fascinating journey through the history of deep-sea exploration, from the myths & legends of the ancient world to storied shipwrecks we can now reach on the bottom, to the first intrepid bathysphere pilots, to the scientists who are just beginning to understand the mind-blowing complexity & ecological importance of the quadrillions of creatures who live in realms long thought to be devoid of life.

Throughout this journey, she learned how vital the deep is to the future of the planet, & how urgent it is that we understand it in a time of increasing threats from climate change,...
