""Deep Water is a major achievement....Bradley's skills both as novelist and essayist converge here to create this wise, compassionate and urgent book, characterized throughout by a clarity of prose and a bracing moral gaze that searches water, self and reader."" —ROBERT MACFARLANE, bestselling author of Underland

In this thrilling work—a blend of history, science, nature writing, and environmentalism—acclaimed writer James Bradley plunges into the unknown to explore the deepest recesses of the natural world.

Seventy-one percent of the earth’s surface is ocean. These waters created, shaped, and continue to sustain not just human life, but all life on Planet Earth, and perhaps beyond it. They serve as the stage for our cultural history—driving human development from evolution through exploration, colonialism, and the modern era of global leisure and trade. They are also the harbingers of the future—much of life on Earth cannot survive if sea levels are too low or too high, temperatures too cold or too warm. Our oceans are vast spaces of immense wonder and beauty, and our relationship to them is innate and awe inspired.

Deep Water is both a lyrically written personal meditation and an intriguing wide-ranging reported epic that reckons with our complex connection to the seas. It is a story shaped by tidal movements and deep currents, lit by the insights of philosophers, scientists, artists, and other great minds. Bradley takes listeners from the atomic creation of the oceans to the wonders within, such as fish migrations guided by electromagnetic sensing. He describes the impacts of human population shifts by boat and speaks directly and uncompromisingly to the environmental catastrophe that is already impacting our lives. It is also a celebration of the ocean’s glories and the extraordinary efforts of the scientists and researchers who are unlocking its secrets. These myriad strands are woven together into a tapestry of life that captures not only our relationship with the planet, but our past, and perhaps most importantly, what lies ahead for us.

A brilliant blend of Robert MacFarlane’s Underland, Susan Casey’s The Underworld, and Simon Winchester’s Pacific and The Atlantic, Deep Water taps into the essence of our planet and who we are.
