Найти книгу: "Oceans"

A level 2 Oxford Bookworms Library graded reader. Written for Learners of English by Barnaby Newbolt. Thousands of years ago, people looked out across an ocean and asked themselves, 'What is on the other side?' And the bravest of them began to travel and find the answers – beautiful islands, frozen lands, different peoples …And there are still interesting questions about the oceans. How do they change our weather? Why does the water go up and down twice a day? Why do most animals and plants live near the land? And what can possibly live at the bottom of the ocean, thousands of metres down, where there is no light? Surely nothing can stay alive in a place like that…

This book presents an up to date view of iron biogeochemistry in the ocean. It encompasses the description of iron speciation, the analytical methods used to measure the different iron forms in seawater and the different iron biogeochemical models.

Fuels, Chemicals and Materials from the Oceans and Aquatic Sources provides a holistic view of fuels, chemicals and materials from renewable sources in the oceans and other aquatic media. It presents established and recent results regarding the use of water-based biomass, both plants and animals,for value-added applications beyond food. The book begins with an introductory chapter which provides an overview of ocean and aquatic sources for the production of chemicals and materials. Subsequent chapters focus on the use of various ocean bioresources and feedstocks, including microalgae, macroalgae, and waste from aquaculture and fishing industries, including fish oils, crustacean and mollusc shells. Fuels, Chemicals and Materials from the Oceans and Aquatic Sources serves as a valuable reference for academic and industrial professionals working on the production of chemicals, materials and fuels from renewable feedstocks. It will also prove useful for researchers in the fields of green and sustainable chemistry, marine sciences and biotechnology. Topics covered include: • Production and conversion of green macroalgae • Marine macroalgal biomass as an energy feedstock • Microalgae bioproduction • Bioproduction and utilization of chitin and chitosan • Applications of mollusc shells • Crude fish oil as a potential fuel

The governance of seas and oceans, defined as all forms of social participation in decision-making on the marine environment, is here mainly from a legal perspective view with the Law of the Sea as a determinant. The book presents the main aspects of maritime law and the history of its construction. The exploitation of living resources, minerals and marine energy reserves, maritime transport, marine ecosystems disturbance by a vessel traffic constantly increasing, are included.

Human health and well-being are tied to the vitality of the global ocean and coastal systems on which so many live and rely. We engage with these extraordinary environments to enhance both our health and our well-being. But, we need to recognize that introducing contaminants and otherwise altering these ocean systems can harm human health and well-being in significant and substantial ways. These are complex, challenging, and critically important themes. How the human relationship to the oceans evolves in coming decades may be one of the most important connections in understanding our personal and social well-being. Yet, our understanding of this relationship is far too limited. This remarkable volume brings experts from diverse disciplines and builds a workable understanding of breadth and depth of the processes – both social and environmental – that will help us to limit future costs and enhance the benefits of sustainable marine systems. In particular, the authors have developed a shared view that the global coastal environment is under threat through intensified natural resource utilization, as well as changes to global climate and other environmental systems. All these changes contribute individually, but more importantly cumulatively, to higher risks for public health and to the global burden of disease. This pioneering book will be of value to advanced undergraduate and postgraduate students taking courses in public health, environmental, economic, and policy fields. Additionally, the treatment of these complex systems is of essential value to the policy community responsible for these questions and to the broader audience for whom these issues are more directly connected to their own health and well-being. «The seas across this planet and their effects on human society and its destiny are a fascinating subject for analysis and insights derived from intellectual inquiry. This diverse and complex subject necessarily requires a blending of knowledge from different disciplines, which the authors of this volume have achieved with remarkable success.» «The following pages in this volume are written in a lucid and very readable style, and provide a wealth of knowledge and insightful analysis, which is a rare amalgam of multi-disciplinary perspectives and unique lines of intellectual inquiry. It is valuable to get a volume such as this, which appeals as much to a non-specialist reader as it does to those who are specialists in the diverse but interconnected subjects covered in this volume.» (From the «Foreword» written by, R K Pachauri, Director General, TERI and Chairman, IPCC)

In the tradition of Dava Sobel's ‘Longitude’ comes sailing expert David Barrie's compelling and dramatic tale of invention and discovery – an eloquent elegy to one of the most important navigational instruments ever created, and the daring mariners who used it to explore, conquer, and map the world.This book is an eloquent elegy to the sextant – the odd-looking instrument that changed the world. It tells the story of how and why the sextant was invented; how it saved the lives of many navigators in wild and dangerous seas—as well as its vital role in man’s attempts to map the world. Among the protagonists in this story are Captain James Cook, Matthew Flinders – the first man to circumnavigate Australia, the great French navigator, Laperouse, who built on Cook's work in the exploring the Pacific during the 1780s, but never made it home, Robert Fitz-Roy of the Beagle, George Vancouver, Frank Worsley of the Endurance, and Joshua Slocum, the redoubtable old ‘lunarian’ and first single-handed round-the-world yachtsman. Much of the book is set amidst the waves of the Pacific ocean as explorers searched for the great southern ocean, charted the coasts of Australia, New Zealand, California, Canada, Alaska as well as the Pacific islands. Their stories are interwoven with the author’s account of his own maiden voyage on Saecwen in 1973, and they are infused with his sense of wonder and dramatic discovery.A heady mix of adventure, science, mathematics and derring-do, Sextant is a timeless tale of sea-faring and exploration, a love letter to the sea which will appeal to the many thousands of readers who loved Dava Sobel’s Longitude as well as the work of Simon Winchester, Patrick O’Brian and Richard Holmes. This is narrative history and storytelling at its best.
