“Fascinating, informative, exhilarating.” —Wall Street Journal
Deep is a voyage from the ocean’s surface to its darkest trenches, the most mysterious places on Earth. Fascinated by the sport of freediving—in which competitors descend great depths on a single breath—James Nestor embeds with a gang of oceangoing extreme athletes and renegade researchers. He finds whales that communicate with other whales hundreds of miles away, sharks that swim in unerringly straight lines through pitch-black waters, and other strange phenomena. Most illuminating of all, he learns that these abilities are reflected in our own remarkable, and often hidden, potential—including echolocation, directional sense, and the profound bodily changes humans undergo when underwater. Along the way, Nestor unlocks his own freediving skills as he communes with the pioneers who are expanding our definition of what is possible in the natural world, and in ourselves.
“A journey well worth taking.” —David Epstein, New York Times Book Review
“Nestor pulls us below the surface into a world far beyond imagining and opens our eyes to these unseen places.” —Dallas Morning News
“This is popular science writing at its best.” —Christian Science Monitor
This exploration of the "human connection to the ocean" begins with free diving, the technique of depth diving on single breaths of air. While free diving may have earned YouTube notoriety as a danger-laden sport with "fringe disciplines" and stunning depth records, Nestor is only briefly fascinated by the "ego-driven competition," and focuses instead on free diving as the elemental mode for accessing the wonders of the ocean. A surfer with a lifelong connection to the ocean, Nestor interpolates his own training to "go deep" with encounters with scientists researching at the limits of ocean knowledge. He avoids the "quasi-religious terms" encountered in others' experiences of deep dives, yet still offers an acute sense of wonder and respect for the ocean, from the disappearing diving traditions of ancient cultures to the diversity of life in earth's deepest trenches. Nestor's explorations of the "outer limits of amphibious abilities" and "latent and unconscious senses" that link humans to our aquatic evolutionary heritage make for a thrilling account, made timely by the rapidly changing state of earth's most expansive environment.
I worked for many years on a rehab unit with high-level spinal patients who no longer had the ability to maintain oxygen levels without a ventilator.
I worked with respiratory therapists and others to teach them to use a technique called Glosso-Pharyngeal Breathing, or GPB. This was invented by a polio patient in the 1950’s and allows patients to use the intact muscles of the tongue, face and throat to push and stack more and more air into the lungs.
One patient with a lung capacity of about 300cc (about 4,000cc prior to injury), was able to inflate his lungs to about 1,000cc every 10-15 seconds. This technique saved his life the night he went home. The ventilator tubing slipped off and his wife was so soundly asleep that she didn’t wake up enough to hear the alarm for over 30 minutes!
This book talks about similar techniques used by freedivers and is very well written.

This was one of the best and most addictive books I’ve read in years! Highly recommend if you have a love or just an interest in the ocean.
Every single page is mind blowing.
This isn't a page turner, it's not "unputdownable," it's so very much more than that. At every turn you will discover things about humans and our fine flippered friends in the sea that will blow your mind. Amazing just doesn't do it justice. Read this, you'll be so much better for it.
