In countries where scarce surface water causes disease and conflict, an abundance of water can bring peace. With the growing impact of climate change, an estimated one third of the world's population lacks fresh water. By 2050 it could well be over half, some five billion people. Alain Gachet, known as the "Wizard of H2O", explores and unravels the interrelated humanitarian, environmental, scientific and geo-political concerns generated by water scarcity. An archaeological explorer and mining engineer, Gachet has developed a technology (using Nasa satellite imagery) to identify massive aquifers beneath the earth's surface using a mathematical algorithm that could completely change our future. As well as exploring our current environmental crisis (and offering some solutions), Gachet gives an account of his extraordinary adventures as a mining engineer both before and since he became an expert in deep groundwater - in Congo; in Libya, where he has an audience with Colonel Gaddafi; in Darfur, where he works alongside refugee agencies to provide water to vast camps, often at risk to his life; in Iraq and in Kurdistan, where he encounters both the Peshmerga and the Yazidi people; and in the Turkana region of Kenya, where his discoveries of vast underground reservoirs have been transformative to the lives of the people in an area plagued by drought and disputes over livestock for generations. Gachet discusses the critical issues of climate change and desertification, melting glaciers and rising sea levels, but this is also a book about the people he meets in some of the world's most challenging zones of conflict and deprivation. Ultimately this is a book of hope as we explore some of the solutions for the future. "If the quest to find high-quality water for millions has a superstar, that person is Alain Gachet. Living a truly adventurous life in a scientific field where underground water is hidden and elusive, he has advanced the science and, at the same time, uniquely served society. This is an exciting story of risk, daring, hydrophilanthropy, and reflection on one of the most important challenges facing humankind." DAVID K. KREAMER, President, International Association of Hydrogeologists

The famous geological research ship Glomar Challenger was a radically new instrument that revolutionized earth science in the same sense that the cyclotron revolutionized nuclear physics, and its deep-sea drilling voyages, conducted from 1968 through 1983, were some of the great scientific adventures of our time. Beginning with the vessel's first cruises, which lent support to the idea of continental drift, the Challenger played a key part in the widely publicized plate-tectonics revolution and its challenge to more conventional theories. Originally published in 1992. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

For the first time ever Roland Huntford presents each man's full account of the race to the South Pole in their own words. In 1910 Robert Falcon Scott and Roald Amundsen set sail for Antarctica, each from his own starting point, and the epic race for the South Pole was on. December 2011 marks the centenary of the conclusion to the last great race of terrestrial discovery. For the first time Scott's unedited diaries run alongside those of both Amundsen and Olav Bjaaland, never before translated into English. Cutting through the welter of controversy to the events at the heart of the story, Huntford weaves the narrative from the protagonists' accounts of their own fate. What emerges is a whole new understanding of what really happened on the ice and the definitive account of the Race for the South Pole.

Tales of the intrepid early naturalists who set sail on dangerous voyages of discovery in the vast, unknown Pacific On the great Pacific discovery expeditions of the "long eighteenth century," naturalists for the first time were commonly found aboard ships sailing forth from European ports. Lured by intoxicating opportunities to discover exotic and perhaps lucrative flora and fauna unknown at home, these men set out eagerly to collect and catalogue, study and document an uncharted natural world. This enthralling book is the first to describe the adventures and misadventures, discoveries and dangers of this devoted and sometimes eccentric band of explorer-scholars. Their individual experiences are uniquely their own, but together their stories offer a new perspective on the extraordinary era of Pacific exploration and the achievements of an audacious generation of naturalists. Historian Glyn Williams illuminates the naturalist's lot aboard ship, where danger alternated with boredom and quarrels with the ship's commander were the norm. Nor did the naturalist's difficulties end upon returning home, where recognition for years of work often proved elusive. Peopled with wonderful characters and major figures of Enlightenment science-among them Louis Antoine de Bouganville, Joseph Banks, John Reinhold Forster, Captain Cook, and Charles Darwin-this book is a gripping account of a small group of scientific travelers whose voyages of discovery were to change perceptions of the natural world.

Ronda forms a compelling narrative of Lewis and Clark's expedition and their encounters with Indians. A story of discovery and suspense, it is told with a modern concern to understand the Indian side as well as the white side in this meeting of two cultures. Illustrations. Maps.
