Below the Edge of Darkness: A Memoir of Exploring Light and Life in the Deep Sea [Audiobook]

A pioneering marine biologist takes us down into the deep ocean to understand bioluminescence - the language of light that helps life communicate in the darkness - and what it tells us about the future of life on Earth in this “thrilling blend of hard science and high adventure. Edith Widder’s childhood dream of becoming a marine biologist was almost derailed in college, when complications from a surgery gone wrong caused temporary blindness. A new reality of shifting shadows drew her fascination to the power of light - as well as the importance of optimism. As her vision cleared, Widder found the intersection of her two passions in oceanic bioluminescence, a little-explored scientific field within Earth’s last great unknown frontier: the deep ocean. With little promise of funding or employment, she leaped at the first opportunity to train as a submersible pilot and dove into the darkness. A thrilling adventure story as well as a scientific revelation, Below the Edge of Darkness reckons with the complicated and sometimes dangerous realities of exploration. Widder shows us how when we push our boundaries and expand our worlds, discovery and wonder follow. These are the ultimate keys to the ocean’s salvation - and thus to our future on this planet.
