Once, the ocean of Tethys stretched across the world. It vanished just before Man appeared on Earth. Dorrik Stow tells of the powerful forces that created and destroyed a great ocean, its marine life, its extinctions, its impact on climate, and the many clues by which scientists have put together its story, stretching back 250 million years.
Oceans make up most of the surface of our blue planet. They may form just a sliver on the outside of the Earth, but they are very important, not only in hosting life, including the fish and other animals on which many humans depend, but in terms of their role in the Earth system, in regulating climate, and cycling nutrients. As climate change, pollution, and over-exploitation by humans puts this precious resource at risk, it is more important than ever that we understand and appreciate the nature and history of oceans. There is much we still do not know about the story of the Earth's oceans, and we are only just beginning to find indications of oceans on other planets. In this book, geologists Jan Zalasiewicz and Mark Williams consider the deep history of oceans, how and when they may have formed on the young Earth — topics of intense current research — how they became salty, and how they evolved through Earth history. We learn how oceans have formed and disappeared over millions of years, how the sea nurtured life, and what may become of our oceans in the future. We encounter some of the scientists and adventurers whose efforts led to our present understanding of oceans. And we look at clues to possible seas that may once have covered parts of Mars and Venus, that may still exist, below the surface, on moons such as Europa and Callisto, and the possibility of watery planets in other star systems.
This book on the current state of knowledge of submarine geomorphology aims to achieve the goals of the Submarine Geomorphology working group, set up in 2013, by establishing submarine geomorphology as a field of research, disseminating its concepts and techniques among earth scientists and professionals, and encouraging students to develop their skills and knowledge in this field. Editors have invited 30 experts from around the world to contribute chapters to this book, which is divided into 4 sections – (i) Introduction & history, (ii) Data & methods, (ii) Submarine landforms & processes and (iv) Conclusions & future directions. Each chapter provides a review of a topic, establishes the state-of-the-art, identifies the key research questions that need to be addressed, and delineates a strategy on how to achieve this. Submarine geomorphology is a priority for many research institutions, government authorities and industries globally. The book is useful for undergraduate and graduate students, and professionals with limited training in this field.
The crash of the Indian plate into Asia is the biggest known collision in geological history, and it continues today. The result is the Himalaya and Karakoram - one of the largest mountain ranges on Earth. The Karakoram has half of the world's highest mountains and a reputation as being one of the most remote and savage ranges of all. In this beautifully illustrated book, Mike Searle, a geologist at the University of Oxford and one of the most experienced field geologists of our time, presents a rich account of the geological forces that were involved in creating these mountain ranges. Using his personal accounts of extreme mountaineering and research in the region, he pieces together the geological processes that formed such impressive peaks.
Stephen Pyne has been described as having a consciousness "composed of equal parts historian, ecologist, philosopher, critic, poet, and sociologist." At this time in history when many people are trying to understand their true relationship with the natural environment, this book offers a remarkable contribution--breathtaking in the scope of its research and exhilarating to read. Pyne takes the reader on a journey through time, exploring the terrain of Europe and the uses and abuses of its lands as well as, through migration and conquest, many parts of the rest of the world. Whether he is discussing the Mediterranean region, Russia, Scandinavia, the British Isles, central Europe, or colonized islands; whether he is considering the impact of agriculture, forestry, or Enlightenment thinking, the author brings an unmatched insight to his subject. Vestal Fire takes its title from Vesta, Roman goddess of the hearth and keeper of the sacred fire on Mount Olympus. But the book's title also suggests the strengths and limitations of Europe's peculiar conception of fire, and through fire, of its relationship to nature. Between the untamed fire of the wilderness and the tended fire of the hearth lies a never-ending dialectic in which human beings struggle to control natural forces and processes that in fact can sometimes be directed but never wholly dominated or contained.
In the time of the Ancients the universe was united—but that was so far in the past that not even memory remains, only the broken artifacts that a few Makers can reshape into their original uses. What survives is shattered into enclaves—some tiny, some ruined, some wild. Into the gaps between settlements, and onto the Road that connects all human reality and the reality that is not human and may never have been human, have crept monsters. Some creatures are men, twisted into inhuman evil; some of them are alien to Mankind— And there are things which are hostile to all life, things which will raven and kill until they are stopped. A Leader has arisen, welding the scattered human settlements together in peace and safety and smashing the enemies of order with an iron fist. In his capital, Dun Add, the Leader provides law and justice. In the universe beyond, his Champions advance—and enforce—the return of civilization. Pal, a youth from the sticks, has come to Dun Add to become a Champion. Pal is a bit of a Maker, and in his rural home he's been able to think of himself as a warrior because he can wield the weapons of the Ancient civilization. Pal has no idea of what he's really getting into in Dun Add. On the other hand, the Leader and Dun Add have no real idea of what might be inside this hayseed with high hopes. THE SPARK: A story of hope and violence and courage. And especially, a story of determination. At the publisher's request, this title is sold without DRM (Digital Rights Management). About The Spark: ". . . entertaining tale combining the feel of Arthurian legend with nifty far-future super science . . ."—Publishers Weekly About David Drake: “Drake deftly weaves a web of political machinations and intrigue that vividly depicts the costs of war. Fans of Patrick O'Brian's Maturin and Aubrey novels will enjoy this intricate, rousing space opera.” —Publishers Weekly “[R]ousing old-fashioned space opera.”—Publishers Weekly “The fun is in the telling, and Mr. Drake has a strong voice. I want more!”—Philadelphia Weekly Press “[S]pace opera is alive and well. This series is getting better as the author goes along…character development combined with first-rate action and memorable world designs.”—SFReader.com “[P]rose as cold and hard as the metal alloy of a tank…rivals Crane and Remarque…”—Chicago Sun-Times “Drake couldn’t write a bad action scene at gunpoint.”—Booklist
A fisherman encounters all the fury, and caprice, and treachery of outer nature in order to win a woman whom on his return he finds to have unconsciously but irrevocably lost her heart to another. But this plainest of stories is worked into genuine tragedy by an exercise of poetic power which, at least in some portions of its display, has very rarely been surpassed in literature. It is difficult to dissent from those who fancy they discover in the author's three volumes a romance, an epic poem, and a drama of real life. There is also in the volumes a charming idyl, full of grace, sweetness, and simplicity. If there be anyone who can rise from the perusal of the book without feeling not only deeply moved, but also enlightened, chastened, and, for at least the moment, improved, "let no such man be trusted."'
