Until a few decades ago, the ocean depths were almost as mysterious and inaccessible as outer space. Oceans cover two-thirds of the earth's surface with an average depth of more than two miles--yet humans had never ventured more than a few hundred feet below the waves. One of the great scientific and archaeological feats of our time has been finally to cast light on the "eternal darkness" of the deep sea. This is the story of that achievement, told by the man who has done more than any other to make it possible: Robert Ballard. Ballard discovered the wreck of the Titanic. He led the teams that discovered hydrothermal vents and "black smokers"--cracks in the ocean floor where springs of superheated water support some of the strangest life-forms on the planet. He was a diver on the team that explored the mid-Atlantic ridge for the first time, confirming the theory of plate tectonics. Today, using a nuclear submarine from the U.S. Navy, he's exploring the ancient trade routes of the Mediterranean and the Black Sea for the remains of historic vessels and their cargo. In this book, he combines science, history, spectacular illustrations, and first-hand stories from his own expeditions in a uniquely personal account of how twentieth-century explorers have pushed back the frontiers of technology to take us into the midst of a world we could once only guess at. Ballard begins in 1930 with William Beebe and Otis Barton, pioneers of the ocean depths who made the world's first deep-sea dives in a cramped steel sphere. He introduces us to Auguste and Jacques Piccard, whose "Bathyscaph"descended in 1960 to the lowest point on the ocean floor. He reviews the celebrated advances made by Jacques Cousteau. He describes his own major discoveries--from sea-floor spreading to black smokers--as well as his technical breakthroughs, including the development of remote-operated underwater vehicles and the revolutionary search techniques that led to the discovery and exploration of the Titanic, the Nazi battleship Bismarck, ancient trading vessels, and other great ships. Readers will come away with a richer understanding of history, earth science, biology, and marine technology--and a new appreciation for the remarkable men and women who have explored some of the most remote and fascinating places on the planet.

Julian "Tusker" Tusk, an American archaeologist, is excavating a shipwreck half a world from home when a research boat catches fire and sinks, killing an old friend. The tragedy sets in motion a dangerous quest for truth that pulls Tusker into a sinister plot spanning 75 years, from World War II Ceylon to modern day Sri Lanka. Along the way, he matches wits with a psychopathic mercenary, discovers a long lost ship with an explosive secret, and falls for a beautiful marine biologist who is at least as strong as he is. In the end, Tusker finds that the truth may lie at the bottom of the sea, with only one way back to the surface.Depth Charge is an old school thriller in the tradition of Fleming, Maclean, and Cussler, with an eye for detail, cunning villains, and narrow escapes. The story is full of wartime secrets, the intersection of religion and politics, and the arcane world of deep technical diving. It takes readers from the smoky halls of 1940s London to the volatile, seductive heat of Sri Lanka and sixty fathoms under the Indian Ocean. Try not to hold your breath.

The charismatic mammals that live in the ocean are a constant source of interest, both for scientists and our society at large. Their biology, behavior, and conservation are of utmost importance, as a vast number of species are currently threatened. Intended for the upper-level undergraduate or graduate student within biology, marine biology, or conservation/environmental science, An Introduction to Marine Mammal Biology and Conservation provides a broad introduction to marine mammal biology using cutting edge information and student-friendly learning tools. The text begins with chapters on the evolution and classification of marine mammals and their general biology. It moves on to discuss the behavior and ecology of different groups of marine mammals, such as polar bears, otters, and cetaceans. Part 3 dives into many different conservation issues facing marine mammals, as well as discussions on how they can be addressed. Closing chapters provide information on how scientists study marine mammals, how society can enjoy observing the animals while making sure they are preserved, and a word to students looking to pursue a career with marine mammals.

Deep Sea Mysteries: Exploring the Depths of the Ocean by Seraphina Blake takes readers on an enthralling journey into the uncharted territories of our planet's oceans. Beyond the continental shelves lies a world of darkness, extreme pressure, and fascinating creatures. This book delves into the history and significance of deep-sea exploration, the social and environmental impacts, and the cutting-edge technology that has made these explorations possible. From the development of deep-sea submersibles post-World War II to the discovery of hydrothermal vents and cold seeps, Blake provides a comprehensive look at the wonders and challenges of the deep sea. Discover how this largely untouched ecosystem holds potential solutions to human diseases and the implications of deep-sea mining on our future. Deep Sea Mysteries is a must-read for anyone intrigued by the ocean's hidden depths and the scientific advancements that allow us to explore them.

This is a completely updated and revised version of a monograph published in 2002 by the NASA History Office under the original title Deep Space Chronicle: A Chronology of Deep Space and Planetary Probes, 1958-2000.
