"The deeper the book ventures into the ocean, the more dramatic and unusual the organisms therein and the people who observe them...Through [Nestor's] eyes and his stories, it's a journey well worth taking."
         -- David Epstein, New York Times Book Review  

"Fascinating, informative, exhilarating book, and, I wager, it will at the very least have you testing how long you can hold your breath."
         -- Wall Street Journal

"An engaging exploration of the depths of the world's oceans and the human connection to the rapidly changing world below. This is popular science writing at its best.

"
         -- Christian Science Monitor

"Rich and illuminating ... A passionate celebration of the possible and the unproven ... [ Deep ] will certainly enrich the thinking of anyone planning to spend time at the beach."
         -- Independent (UK)

"Truly breathtaking ... Nestor gets right in with the competitors and rogue scientists who are unearthing mysteries of the deep and its inhabitants that we can't even imagine, in a book that's engaging and eye-popping."
         -- Esquire

"Nestor is crisp with his fun, seafaring facts; he is sober with his sprinkling of environmental bulletins. The book never preaches, and it's a zippy read."
         -- Los Angeles Times

"Freediving, the sport that harnesses the mammalian dive reflex to survive deep plunges, can be a boon for marine researchers, avers James Nestor. We meet a salty cast of them, such as the 'aquanauts' of Aquarius, a marine analogue of the International Space Station submerged off the Florida Keys. Equally mesmeric are Nestor's own adventures, whether spotting bioluminescent species from a submarine in the bathypelagic zone, or freediving himself -- and voyaging into humanity's amphibious origins in the process."
         -- Nature (UK)

" Put Deep at the top of your reading list. This book will do for the oceans what Cosmos did for space. It's mind-bending, intrepid, and inspiring."
         -- Po Bronson

"With verve and humor, the author describes his own risk-taking attempts to understand the ocean's ancient secrets and future potential and the daring and brilliant people who have dedicated their lives to probing deeper ... [Nestor's] writing is sharp, colorful, and thrilling ... Bring[s] the ocean to life from a research perspective as well as a human one. An adventurous and frequently dazzling look at our planet's most massive habitat."
         -- Kirkus

"A thrilling account, made timely by the rapidly changing state of earth's most expansive environment."
         -- Publishers Weekly
