Marine Geochemistry offers a fully comprehensive and integrated treatment of the chemistry of the oceans, their sediments and biota. The first edition of the book received strong critical acclaim and was described as ‘a standard text for years to come.’ This third edition of Marine Geochemistry has been written at a time when the role of the oceans in the Earth System is becoming increasingly apparent. Following the successful format adopted previously, this new edition treats the oceans as a unified entity, and addresses the question ‘how do the oceans work as a chemical system?’ To address this question, the text has been updated to cover recent advances in our understanding of topics such as the carbon chemistry of the oceans, nutrient cycling and its effect on marine chemistry, the acidification of sea water, and the role of the oceans in climate change. In addition, the importance of shelf seas in oceanic cycles has been re-evaluated in the light of new research. Marine Geochemistry offers both undergraduate and graduate students and research workers an integrated approach to one of the most important reservoirs in the Earth System.

Marine geochemistry uses chemical elements and their isotopes to study how the ocean works in terms of ocean circulation, chemical composition, biological activity and atmospheric CO2 regulation. This rapidly growing field is at a crossroad for many disciplines (physical, chemical and biological oceanography, geology, climatology, ecology, etc.). It provides important quantitative answers to questions such as: What is the deep ocean mixing rate? How much atmospheric CO2 is pumped by the ocean? How fast are pollutants removed from the ocean? How do ecosystems react to anthropogenic pressure? This text gives a simple introduction to the concepts, the methods and the applications of marine geochemistry with a particular emphasis on isotopic tracers. Overall introducing a very large number of topics (physical oceanography, ocean chemistry, isotopes, gas exchange, modelling, biogeochemical cycles), with a balance of didactic and indepth information, it provides an outline and a complete course in marine geochemistry. Throughout, the book uses a hands-on approach with worked out exercises and problems (with answers provided at the end of the book), to help the students work through the concepts presented. A broad scale approach is take including ocean physics, marine biology, ocean-climate relations, remote sensing, pollutions and ecology, so that the reader acquires a global perspective of the ocean. It also includes new topics arising from ongoing research programs. This textbook is essential reading for students, scholars, researchers and other professionals.

"This is undoubtedly a major contribution to the field. David Burdige's scholarship is cutting edge."--Bernard P. Boudreau, Dalhousie University "Burdige has written a wonderfully exhaustive review spanning all aspects of marine sedimentary geochemistry. Generous background welcomes the newcomer, while ample depth and breadth stimulate the savvy expert. The discussions are built from the latest work in biogeochemistry and microbial ecology. And in the tradition of Robert Berner's classic treatment of early diagenesis, Burdige handles reaction pathways and transport processes rigorously and quantitatively. This nicely written, well-illustrated survey suits both the reference shelf and the classroom."--Timothy W. Lyons, University of California, Riverside "This book fills a gaping hole in our field. While certain to be used by specialists, it also provides background and ancillary information so as to reach allied fields. Burdige has done a remarkable job in providing the right balance of background theory, real-world implementation, and examples from the literature."--Rick Murray, Boston University "David Burdige's book reviews and develops the ideas that emerged in the field of geochemistry over the last twenty-five years. It is a significant contribution. The scholarship is clearly sound, with excellent and comprehensive references to the latest work. I have no doubt it will be useful to any students who wish to learn the subject."--Michael Krom, Leeds University Earth and Biosphere Institute

Even at the beginning of the new millenium the rare earths still remain, to a certain extent, a mystery. The chapters in this volume will help to unravel some of these. In the filling of the 4f electronic orbitals the lanthanides defy the elementary aufbau principle that underlies the periodic sequence of the elements, and the authors of the first chapter introduce the readers to the basic physics of the orbital collapse leading to that failure. Furthermore an explanation is offered in terms of double-well potentials. The phenomenon is illustrated using the valence transitions observed in some of the rare earth atoms, including Sm group metals and the higher oxides of cerium, praseodymium and terbium. In the second chapter the synthesis and structure of the many types of rare earth halides are described. They have been described as simple, complex, binary, ternary and multinuclear complex, and other categories needed to deal with the most studied of the rare earth compounds. The structure types are skillfully illustrated to show the elementary architecture of each type. In chapter three the authors discuss the science and applications of rare earth super ionic conductors as solid electrolytes. Conduction by oxygen and fluorine anions as well as hydrogen and other cations associated with these electrolytes is emphasized. They deal with extrinsic and intrinsic types together with their associated structures and structural types including structural defects. The chapter concludes with an outline of the many applications of solid electrolytes. Chapter four introduces the reader to the principles that underlie thermoluminescence and its application to dosimetry and provides detailed information on the R-activated phosphors that support dosimetry. This is a selective review of detailed literature based on the areas making most progress. The final chapter elaborates on the data gained by the studies and interpretation around the analytical separation of the individual rare earth elements utilizing chromatographic techniques. The authors describe the fundamental chemistry that underpins contemporary analytical separation techniques for lanthanide separation and analysis. This is done after a description of the rich assortment of separation methods in use has been introduced.

Marine systems vary in their sensitivities to perturbation. Perturbation may be insidious – such as increasing eutrophication of coastal areas – or it may be dramatic – such as a response to an oil spillage or some other accident. Climate change may occur incrementally or it may be abrupt, and ecosystem resilience is likely to be a complex function of the interactions of those assemblages or species mediating key biogeochemical processes. Biogeochemistry of Marine Systems considers issues of marine system resilience, focusing on a range of marine systems that exemplify major global province types but are also interesting and topical in their own right, on account of their sensitivity to natural or anthropogenic change or their importance as ecological service providers. Authors concentrate on advances of the last decade.
