Sealab is the underwater Right Stuff: the compelling story of how a US Navy program sought to develop the marine equivalent of the space station—and forever changed man’s relationship to the sea. While NASA was trying to put a man on the moon, the US Navy launched a series of daring experiments to prove that divers could live and work from a sea-floor base. When the first underwater “habitat” called Sealab was tested in the early 1960s, conventional dives had strict depth limits and lasted for only minutes, not the hours and even days that the visionaries behind Sealab wanted to achieve—for purposes of exploration, scientific research, and to recover submarines and aircraft that had sunk along the continental shelf. The unlikely father of Sealab, George Bond, was a colorful former country doctor who joined the Navy later in life and became obsessed with these unanswered questions: How long can a diver stay underwater? How deep can a diver go? Sealab never received the attention it deserved, yet the program inspired explorers like Jacques Cousteau, broke age-old depth barriers, and revolutionized deep-sea diving by demonstrating that living on the seabed was not science fiction. Today divers on commercial oil rigs and Navy divers engaged in classified missions rely on methods pioneered during Sealab. Sealab is a true story of heroism and discovery: men unafraid to test the limits of physical endurance to conquer a hostile undersea frontier. It is also a story of frustration and a government unwilling to take the same risks underwater that it did in space. Ben Hellwarth, a veteran journalist, interviewed many surviving participants from the three Sealab experiments and conducted extensive documentary research to write the first comprehensive account of one of the most important and least known experiments in US history.

A missing relative... Something of value was buried beneath the underwater dome city of Marinia...something that had already cost one man's life, caused another man's kidnapping and gravely affected still another man's future. Expelled from the Sub-Sea Academy on trumped-up charges, Jim Eden wasn't about to wait around to prove his innocence. As soon as he leaned that his uncle mysteriously disappeared while mining uranium at the bottom of hazardous Eden Deep, Jim knew what he had to do...and that he had to do it fast. So he headed for the vast dome city - location of the great mining colony at the bottom of the sea - to pick up any clues to his uncle's disappearance. But once he had entered the undersea metropolis, the wrong people had his number...and they were determined that Jim would sink forever without a trace.

Treachery, greed, and a gargantuan sea monster threaten the inhabitants of a high-tech, deep-water research station in this thrilling undersea science fiction adventure A three-time Hugo Award winner and modern master of hard science fiction now departs from outer space for a vast, unexplored realm that is equally perilous and mysterious. Allen Steele’s Oceanspace is a heart-racing near-future adventure of danger and discovery unfolding in the dark, cold, and merciless depths of the ocean. The undersea research facility Tethys is a technological wonder, self-sufficient and seemingly impervious to natural danger. Located off the coast of Florida deep beneath the surface of the water, the station supports a robotic mining operation on the ocean floor and facilitates the ongoing scientific exploration of Earth’s last frontier. But while on a routine assignment with his colleague Peter Lipscomb, submersible pilot Joe Niedzwiecki comes face to face with something incredible and alive, and only luck—and Peter’s quick actions—can save them. Peter’s wife, a marine biologist named Judith, is determined to uncover the secrets of the mysterious leviathan that destroyed Joe’s sub and nearly killed him. But the strange creature prowling the dark waters is only one of the dangers confronting Tethys.
