Paleomagnetism is the study of the fossil magnetism in rocks. It has been paramount in determining that the continents have drifted over the surface of the Earth throughout geological time. The fossil magnetism preserved in the ocean floor has demonstrated how continental drift takes place through the process of sea-floor spreading. The methods and techniques used in paleomagnetic studies of continental rocks and of the ocean floor are described and then applied to determining horizontal movements of the Earth's crust over geological time. An up-to-date review of global paleomagnetic data enables 1000 million
years of Earth history to be summarized in terms of the drift of the major crustal blocks over the surface of the Earth.
The first edition of McElhinny's book was heralded as a "classic and definitive text." It thoroughly discussed the theory of geomagnetism, the geologic
reversals of the Earth's magnetic field, and the shifting of magnetic poles. In the 25 years since the highly successful first edition of Palaeomagnetism and Plate Tectonics (Cambridge, 1973) the many advances in the concepts, methodology, and insights into paleomagnetism warrant this new treatment. This completely updated and revised edition of Paleomagnetism: Continents and Oceans will be a welcome resource for a broad audience of earth scientists as well as laypeople curious about magnetism, paleogeography, geology, and plate tectonics.
Because the book is intended for a wide audience of geologists, geophysicists, and oceanographers, it balances the mathematical and descriptive aspects of each topic.

European explorers were captivated by the seemingly endless bounty of natural resources on Cape Cod Bay. One Englishman declared that the codfish were so thick one "could" walk on their backs. Early settlers quickly learned how to harness the bay's resources and excelled at shore whaling, shipping and salt making. But as these new industries flourished, the native Wampanoag, who helped the fledgling colony to take root, nearly vanished. Author Theresa Mitchell Barbo's skillful narrative weaves together the natural and cultural histories of the bay, highlighting some of the region's diverse milestones- from the drafting of the Mayflower Compact in 1620 to the establishment of the Pilgrim Nuclear Power Plant 350 years later. "Cape Cod Bay: A History of Salt & Sea" inspires new appreciation for this storied and stunning seascape, and underscores the importance of new efforts to preserve the bay's unique ecosystem.

Appreciating that coastal areas are under threat from misuse and overuse worldwide, this book reviews the need for marine conservation, summarizes general measures for ocean and coastal conservation, and explains the rationale for establishing marine protected areas. The second half of the book is a guideline for designing and implementing protected areas in order to make them viable and long-lasting in their effectiveness.

'Seawater' has been substantially updated in this second edition to take account of recent developments in marine science. Sections dealing with difficult physical and chemical concepts have been developed on the basis of feedback from the first edition, making this an ideal learning tool for oceanography students.

Chapter 1 summarizes the special properties of water and the role of the oceans in the hydraulic cycle. The distribution of temperature and salinity in the oceans and how they influence water density and movements is then discussed. Light and sound in seawater are considered next, along with some uses of acoustics. These are followed by an examination of the composition and behaviour of dissolved constituents, including such topics as residence times, the control of pH, and redox relationships.
Finally, the history of seawater and its role in global cycles is reviewed, with special reference to climatic change and the CO2 problem.

The subject of geomathematics focuses on the interpretation and classification of data from geoscientific and satellite sources, reducing information to a comprehensible form and allowing the testing of concepts. Sphere oriented mathematics plays an important part in this study and this book provides the necessary foundation for graduate students and researchers interested in any of the diverse topics of constructive approximation in this area. This book bridges the existing gap between monographs on special functions of mathematical physics and constructive approximation in Euclidean spaces. The primary objective is to provide readers with an understanding of aspects of approximation by spherical harmonics, such as spherical splines and wavelets, as well as indicating future directions of research. Scalar, vectorial, and tensorial methods are each considered in turn. The concentration on spherical splines and wavelets allows a double simplification; not only is the number of independent variables reduced resulting in a lower dimensional problem, but also radial basis function techniques become applicable. When applied to geomathematics this leads to new structures and methods by which sophisticated measurements and observations can be handled more efficiently, thus reducing time and costs.

'Introductory Dynamical Oceanography' 2nd ed provides an introduction to Dynamical Physical Oceanography at a level suitable for senior year undergraduate students in the sciences and for graduate students entering oceanography. It aims to present the basic objectives, procedures and successes and to state some of the present limitations of dynamical oceanography and its relations to descriptive physical oceanography.
The first edition has been thoroughly revised and updated and the new work includes reference to the Practical Salinity Scale 1978, the International Equation of State 1980 and the beta-spiral technique for calculating absolute currents from the density distribution. In addition the description of mixed-layer models has been updated and the chapters on Waves and on Tides have been substantially revised and enlarged, with emphasis on internal waves in the Waves chapter. While the text is self-contained readers are recommended to acquaint themselves with the general aspects of descriptive (synoptic) oceanography in order to be aware of the character of the ocean which the dynamical oceanographer is attempting to explain by referring to Pickard and Emery's 'Descriptive Physical Oceanography' 4th edition.

Earth is constantly changing. Wind, water, and even humans change Earth's surface. The land is broken down and worn away by erosion. Introduce students to weathering and erosion with this science reader that features easy-to-read text. Nonfiction text features include a glossary, index, and detailed images to facilitate close reading and help students connect back to the text. Aligned to state and national standards, the book also includes a fun and engaging science experiment to develop critical thinking and help students practice what they have learned.

Climate Physics is a modern subject based on a space-era understanding of the physical properties of the atmosphere and ocean, their planetary-scale history and evolution, new global measurement systems and sophisticated computer models, which collectively make quantitative studies and predictions possible. At the same time, interest in understanding the climate has received an enormous boost from the concern generated by the realization that rapid climate change, much of it forced by the relentless increase in population and industrialization, is potentially a serious threat to the quality of life on Earth. Our ability to resist and overcome any such threat depends directly on our ability to understand what physical effects are involved and to predict how trends may develop. In an introductory course like that presented here, we want to clarify the basics, topic by topic, and see how far we can get by applying relatively simple Physics to the climate problem. This provides a foundation for more advanced work, which we can identify and appreciate at this level although of course a full treatment requires more advanced books, of which there are many.

Climate change is a major challenge facing modern society. The chemistry of air and its influence on the climate system forms the main focus of this book. Vol. 2 of Chemistry of the Climate System takes a problem-based approach to presenting global atmospheric processes, evaluating the effects of changing air compositions as well as possibilities for interference with these processes through the use of chemistry.

Sand, salt, iron, copper, oil and lithium. They built our world, and they will transform our future.

These are the six most crucial substances in human history. They took us from the Dark Ages to the present day. They power our computers and phones, build our homes and offices, and create life-saving medicines. But most of us take them completely for granted.

In Material World, Ed Conway travels the globe - from the sweltering depths of the deepest mine in Europe, to spotless silicon chip factories in Taiwan, to the eerie green pools where lithium originates - to uncover a secret world we rarely see. Revealing the true marvel of these substances, he follows the mind-boggling journeys, miraculous processes and little-known companies that turn the raw materials we all need into products of astonishing complexity.

As we wrestle with climate change, energy crises and the threat of new global conflict, Conway shows why these substances matter more than ever before, and how the hidden battle to control them will shape our geopolitical future. This is the story of civilisation - our ambitions and glory, innovations and appetites - from a new perspective: literally from the ground up.
