The previously classified story of the eccentric researchers who invented cutting-edge underwater science to lead the Allies to D-Day victory In August 1942, more than 7,000 Allied troops rushed the beaches of Normandy, France, in an all but-forgotten landing. Only a small fraction survived unscathed. It was two summers before D-Day, and the Allies realized that they were in dire need of underwater intelligence if they wanted to stand a chance of launching another beach invasion and of winning the war. Led by the controversial biologists J. B. S. Haldane and Dr. Helen Spurway, an ingenious team of ragtag scientists worked out of homemade labs during the London Blitz. Beneath a rain of bombs, they pioneered thrilling advances in underwater reconnaissance through tests done on themselves in painful and potentially fatal experiments. Their discoveries led to the safe use of miniature submarines and breathing apparatuses, which ultimately let the Allies take the beaches of Normandy. Blast injury specialist Dr. Rachel Lance unpacks the harrowing narratives of these experiments while bringing to life the men and women whose brilliance and self-sacrifice shaped the outcome of the war, including their personal relationships with one another and the ways they faced skepticism and danger in their quest to enable Allied troops to breathe underwater. The riveting science leading up to D-Day has been classified for generations, but Chamber Divers finally brings these scientists’ stories—and their heroism—to light.

“Superbly written and action-packed, The Last Dive ranks with such adventure classics as The Perfect Storm and Into Thin Air.”—Tampa Tribune Spurred on by a fatal combination of obsession and ambition, Chris and Chrisy Rouse, an experienced father-son scuba diving team, hoped to achieve wide-spread recognition for their outstanding and controversial diving skills by solving the secrets of a mysterious, undocumented, World War II German U-boat that lay only a half day’s mission from New York Harbor. The Rouses found the ultimate cost of chasing their personal challenge: death from what divers dread the most—decompression sickness, or “the bends.” In this gripping recounting of their tragedy, author Bernie Chowdhury, himself an expert diver, explores the thrill-seeking, high-risk world of deep sea diving, its legendary figures, most celebrated triumphs, and notorious tragedies.

Cave divers are the elite, and this is their story--a story of pushing the limits of technology and human endurance.

U.S. Navy Diving Manual The US Navy first provided a diving manual for training and operational guidance in 1905, and the first book titled Diving Manual was published in 1916. Since then the U.S. Navy Diving Manual evolved over the decades to be regarded as an essential and ultimate resource for modern recreational, commercial and military divers. There have been several published versions, each one updating the content of the previous version. Revision 7 Change A is the latest version released in April 2018 and includes major updates and changes. This extensive technical manual is over 1000 pages and spread over 5 Volumes with 18 Chapters. This is essential reading for anyone serious about diving.

While the effects of pressure change are readily quantified in physics, chemistry, and engineering applications, the physiology, medicine, and biology of pressure changes in living systems are much more complicated. This complex science translated to technical diving is discussed in a five-part series, with each topic self-contained and strategical

And Then There Were None meets The Last Breath in this tense and suspenseful locked-room thriller that takes place inside a hyperbaric chamber from the author of the “brilliant, twisted, and oh so clever” (Chris Whitaker, New York Times bestselling author) novel The Last Thing to Burn. Six experienced saturation divers are locked inside a hyperbaric chamber. Calm and professional, they know that rapid decompression would be fatal and so they work in shifts, breathing helium, and surviving in hot, close quarters. Then one of them is found dead in his bunk. With four days of decompression to go before the locked hatch to the chamber can be safely opened, the group must watch one another’s backs at all times. And when another diver is discovered unresponsive, everyone is on edge. What…or who…is taking them out one by one? And will any of them still be alive by the time the four days is up or will paranoia, exhaustion, suspicion, and pressure destroy them all?

One of "The Most Fascinating Books WIRED Read in 2020" "One part science book, one part historical narrative, one part memoir . . . harrowing and inspiring.”—The Wall Street Journal How a determined scientist cracked the case of the first successful—and disastrous—submarine attack On the night of February 17, 1864, the tiny Confederate submarine HL Hunley made its way toward the USS Housatonic just outside Charleston harbor. Within a matter of hours, the Union ship’s stern was blown open in a spray of wood planks. The explosion sank the ship, killing many of its crew. And the submarine, the first ever to be successful in combat, disappeared without a trace. For 131 years the eight-man crew of the HL Hunley lay in their watery graves, undiscovered. When finally raised, the narrow metal vessel revealed a puzzling sight. There was no indication the blast had breached the hull, and all eight men were still seated at their stations—frozen in time after more than a century. Why did it sink? Why did the men die? Archaeologists and conservationists have been studying the boat and the remains for years, and now one woman has the answers. In the Waves is much more than just a military perspective or a technical account. It’s also the story of Rachel Lance’s single-minded obsession spanning three years, the story of the extreme highs and lows in her quest to find all the puzzle pieces of the Hunley. Balancing a gripping historical tale and original research with a personal story of professional and private obstacles, In the Waves is an enthralling look at a unique part of the Civil War and the lengths one scientist will go to uncover its secrets.
