"Ocean Biogeochemical Dynamics" provides a broad theoretical framework upon which graduate students and upper-level undergraduates can formulate an understanding of the processes that control the mean concentration and distribution of biologically utilized elements and compounds in the ocean. Though it is written as a textbook, it will also be of interest to more advanced scientists as a wide-ranging synthesis of our present understanding of ocean biogeochemical processes.

The first two chapters of the book provide an introductory overview of biogeochemical and physical oceanography. The next four chapters concentrate on processes at the air-sea interface, the production of organic matter in the upper ocean, the remineralization of organic matter in the water column, and the processing of organic matter in the sediments. The focus of these chapters is on analyzing the cycles of organic carbon, oxygen, and nutrients.

The next three chapters round out the authors' coverage of ocean biogeochemical cycles with discussions of silica, dissolved inorganic carbon and alkalinity, and CaCO3. The final chapter discusses applications of ocean biogeochemistry to our understanding of the role of the ocean carbon cycle in interannual to decadal variability, paleoclimatology, and the anthropogenic carbon budget. The problem sets included at the end of each chapter encourage students to ask critical questions in this exciting new field. While much of the approach is mathematical, the math is at a level that should be accessible to students with a year or two of college level mathematics and/or physics.

"This textbook is a monumental and masterful achievement, and the authors should be congratulated both for taking on this important task and for the end result... Every serious student and post-doc in this discipline, and all senior practitioners, should purchase or borrow a copy of this book and read it from cover to cover."--David M. Karl, Bulletin of the American Society for Limnology and Oceanography "Readers of Environmental Conservation with an interest in marine biogeochemistry and earth system science are encouraged to purchase or borrow this book. It is a comprehensive text on a complex and timely topic, and is one that will enlighten students and professionals alike. The authors are to be congratulated on their tour-de-force."--Peter Burkill, Environmental Conservation
