A vivid tour of the Earth's last frontier, a remote and mysterious realm that nonetheless lies close to the heart of even the most land-locked reader. The sea covers seven-tenths of the Earth, but we have mapped only a small percentage of it. The sea contains millions of species of animals and plants, but we have identified only a few thousand of them. The sea controls our planet's climate, but we do not really understand how. The sea is still the frontier, and yet it seems so familiar that we sometimes forget how little we know about it. Just as we are poised on the verge of exploiting the sea on an unprecedented scale—mining it, fertilizing it, fishing it out—this book reminds us of how much we have yet to learn. More than that, it chronicles the knowledge explosion that has transformed our view of the sea in just the past few decades, and made it a far more interesting and accessible place. From the Big Bang to that far-off future time, two billion years from now, when our planet will be a waterless rock; from the lush crowds of life at seafloor hot springs to the invisible, jewel-like plants that float at the sea surface; from the restless shifting of the tectonic plates to the majestic sweep of the ocean currents, Kunzig's clear and lyrical prose transports us to the ends of the Earth. Originally published in hardcover as The Restless Sea.

“Should be required reading. . . . A gripping and all-too-timely account of what in more ways than one is turning out to be a very costly and questionably necessary race to the bottom. . . . Trethewey rises to the occasion here, relating in absorbing detail the ebb and flow of conflicting interests that tussle down among the vents and ridges of the hadal zone. It is all highly readable, and it is all deeply ominous.”—Simon Winchester, New York Times Book Review ?The dramatic and action-packed story of the last mysterious place on earth—the world’s seafloor—and the deep-sea divers, ocean mappers, marine biologists, entrepreneurs, and adventurers involved in the historic push to chart it, as well as the opportunities, challenges, and perils this exploration holds now and for the future. Five oceans—the Atlantic, the Pacific, the Indian, the Arctic, and the Southern—cover approximately 70 percent of the earth. Yet we know little about what lies beneath them. By the early 2020s, less than twenty-five percent of the ocean’s floor has been charted, most close to shorelines, and over three quarters of the ocean lies in in what is called the Deep Sea, depths below a thousand meters. Now, the race is on to completely map the ocean’s floor by 2030—an epic project involving scientists, investors, militaries, and private explorers who are cooperating and competing to get an accurate reading of this vast terrain and understand its contours and environment. In The Deepest Map, Laura Trethewey documents this race to the bottom, following global efforts around the world, from crowdsourcing to advances in technology, recent scientific discoveries to tales of dangerous dives in untested and costly submersibles. The lure of ocean exploration has attracted many, including the likes of James Cameron, Richard Branson, Ray Dalio, and Eric Schmidt. The Deepest Map follows a cast of intriguing characters, from early mappers such as Marie Tharp, a woman working in the male-dominated fields of oceanography and geology whose discoveries have added significantly to our knowledge; Victor Vescovo, a man obsessed with reaching the deepest depths of each of the five oceans, and his young, brilliant, and fearless mapper Cassie Bongiovanni; and the diverse entrepreneurs looking to explore and exploit this uncharted territory and its resources. In The Deepest Map, ocean discovery converges with humanity's origin story; in mapping the ocean floor, scientists are actively tracing our roots back to the most inhospitable places on earth where life began—and flourished. But for every conservationist looking to protect the seafloor, there are others who see its commercial potential. Will a new map exacerbate pollution and the degradation of this natural resource? How will the race remake political power structures in years to come? Trethewey probes these questions as countries and conglomerates wrestle over the riches that may lie at the bottom of the sea. The future of humanity depends on our ability to protect this vast, precious, and often ignored resource. A true tale of science, nature, technology, and an extreme outdoor adventure The Deepest Map illuminates why we love—and fear—the earth’s final frontier and is a crucial addition to the increasingly urgent conversation about climate change.

Her maps of the ocean floor have been called "one of the most remarkable achievements in modern cartography", yet no one knows her name. Soundings is the story of the enigmatic, unknown woman behind one of the greatest achievements of the 20th century. Before Marie Tharp, geologist and gifted draftsperson, the whole world, including most of the scientific community, thought the ocean floor was a vast expanse of nothingness. In 1948, at age 28, Marie walked into the newly formed geophysical lab at Columbia University and practically demanded a job. The scientists at the lab were all male; the women who worked there were relegated to secretary or assistant. Through sheer willpower and obstinacy, Marie was given the job of interpreting the soundings (records of sonar pings measuring the ocean's depths) brought back from the ocean-going expeditions of her male colleagues. The marriage of artistry and science behind her analysis of this dry data gave birth to a major work: the first comprehensive map of the ocean floor, which laid the groundwork for proving the then-controversial theory of continental drift. When combined, Marie's scientific knowledge, her eye for detail and her skill as an artist revealed not a vast empty plane, but an entire world of mountains and volcanoes, ridges and rifts, and a gateway to the past that allowed scientists the means to imagine how the continents and the oceans had been created over time. Just as Marie dedicated more than twenty years of her professional life to what became the Lamont Geological Observatory, engaged in the task of mapping every ocean on Earth, she dedicated her personal life to her great friendship with her co-worker, Bruce Heezen. Partners in work and in many ways, partners in life, Marie and Bruce were devoted to one another as they rose to greater and greater prominence in the scientific community, only to be envied and finally dismissed by their beloved institute. They went on together, refining and perfecting their work and contributing not only to humanity's vision of the ocean floor, but to the way subsequent generations would view the Earth as a whole. With an imagination as intuitive as Marie's, brilliant young writer Hali Felt brings to vivid life the story of the pioneering scientist whose work became the basis for the work of others scientists for generations to come.

Presents an illustrated, A-Z encyclopedia with more than 600 entries providing information on topics related to marine science.

Meet several scientists who study the animals and environment at the bottom of the ocean floor.

The Sun is so powerful, so much bigger than us, that it is a terrifying subject. Yet though we depend on it, we take it for granted. Amazingly the first book of its kind, CHASING THE SUNis a cultural and scientific history of our relationship with the star that gives us life. Richard Cohen, applying the same mix of wide-ranging reference and intimate detail that won outstanding reviews for By the Sword, travels from the ancient Greek astronomers to modern-day solar scientists, from Stonehenge to Antarctica (site of the solar eclipse of 2003, when penguins were said to sing), Mexico's Aztecs to the Norwegian city of Tromso, where for two months of the year there is no Sun at all. He introduces us to the crucial 'sunspot cycle' in modern economics, the religious dances of Indian tribesmen, the histories of sundials and calendars, the plight of migrating birds, the latest theories of global warming, and Galileo recording his discoveries in code, for fear of persecution. And throughout, there is the rich Sun literature -- from the writings of Homer through Dante and Nietzsche to Keats, Shelley and beyond. Blindingly impressive and hugely readable, this is a tour de force of narrative non-fiction.

The book discusses the ways in which high hydrostatic pressure (i.e. water pressure) affects all grades of life which thrive at pressures much greater those in our normal environment. The deep sea is the best known high pressure environment, where pressures reach a thousand times greater than those at the surface, yet it is populated by a variety of animals and microorganisms. The earth’s crust supports microorganisms which live in water filled pores at high pressure. In addition, the load bearing joints of animals like ourselves experience pulses of hydrostatic pressure of a magnitude similar to the pressure at mid ocean depths. These pressures affect molecular structures and biochemical reactions. Basic cellular processes are drastically affected – the growth and division of cells, the way nerves conduct impulses and the chemical reactions which provide energy. Adaptation to high pressure also occurs in complex physiological systems such as those which provide buoyancy. Probably the greatest challenge to our understanding of adaptation to high pressure is the stabilisation of the nervous system of deep sea animals to avoid convulsions which pressure causes in shallow water animals. Additionally the book provides insight into the engineering required to study life at high pressure: equipment which can trap small deep sea animals and retrieve them at their high pressure, equivalent equipment for microorganisms, laboratory microscopes which can focus on living cells under high pressure, incubators for bacteria which require high pressure to grow, high pressure aquaria for marine animals and lastly and briefly, manned and unmanned submersible vessels, Landers and deep drill hole sampling. Rather like the organisms studied many laboratory instruments have been adapted to function at high pressure.

Discusses the history of various topics related to oceans and oceanography, covering mapping, the origins of ocean basics, the ocean floor, measurement of depth and flow, the creatures that inhabits the depths of the sea, and the adventures of modern explorers.
