Chemical Oceanography: Element Fluxes in the Sea

Description

Chemical Oceanography: Element Fluxes in the Sea focuses on the use of chemical distributions to understand mechanisms of physical, chemical, biological, and geological processes in the ocean. After an introduction describing observed chemical concentrations, chapters focus on using chemical tracers to determine fluxes on a variety of time scales. Long-term chemical cycles are dominated by exchanges between seawater and land, sediments, and underwater volcanoes. Biological and ocean mixing processes dominate internal chemical cycles that respond to changes on hundred- to thousand-year time scales. Stable and radioactive isotopes trace the fluxes of nutrients and carbon to quantify the rates and mechanisms of chemical cycles. Anthropogenic influences - which have grown to be of the same magnitude as some natural cycles - are a specific focus throughout the book. Discussion boxes and quantitative problems help instructors to deepen student learning. Appendices enhance the book's utility as a reference text for students and researchers.

Steven R. Emerson has been a professor of Oceanography at the University of Washington for about 40 years. He taught Chemical Oceanography for most of this period while being the major advisor to 12 Ph.D. students and an equal number of post-docs. His research focuses on fluxes at the air-sea interface and the sediment-ocean interface. He is a fellow of the American Geophysical Union and the Geochemical Society. Roberta C. Hamme is an associate professor in the School of Earth and Ocean Sciences at the University of Victoria, and holds a Canada Research Chair in Ocean Carbon Dynamics. She has taught upper-level undergraduate Chemical Oceanography since 2007. Her research focuses on understanding and quantifying the natural mechanisms that transport carbon from the surface ocean to the deep. Her main tools are measurements of dissolved gases, both bioactive gases such as oxygen and inert gases such as neon, argon, and krypton.

'Chemical Oceanography: Element Fluxes in the Sea is completely updated from the previous version. The new version cites up-to-date, peer-reviewed literature, and includes compelling figures, discussion boxes, and problems at the end of each chapter. In addition, the links to MATLAB and Python toolboxes are a great resource. In my opinion, this is the best chemical oceanography textbook currently available for both undergraduate and graduate level courses.' Annie Bourbonnais, University of South Carolina 'The choice of contents for a Chemical Oceanography textbook is, to some extent, a Rorschach test of the authors' view of the field. In their focus on element fluxes affected by life in the oceans, Emerson and Hamme seek to navigate the narrow channel between attention to detail, a hallmark of quantitative ocean science, and the desire to share the fabulous panorama that is the field as a whole.' Andrew Dickson, Scripps Institution of Oceanography 'In their outstanding and exceptionally well-structured textbook, Emerson and Hamme transform the way we think about chemical oceanography. While the distribution of chemical tracers in the ocean still provides the foundation of their textbook, they organize it around the biogeochemical transformations that govern these distributions. A particular focus is the question of how fast these processes operate and how we can measure these rates. To this end, they introduce many modern techniques involving various isotope systems and transient tracers in a way no other textbook has achieved so far. This is a must read for any student, postdoc, and researcher in the field, especially in these rapidly changing times.' Nicolas Gruber, ETH Zurich 'A readable, comprehensive, authoritative account, by two distinguished chemical oceanographers, of what we know about chemical processes in the oceans, and how we have learned it. The book features deep descriptions of the oceanic cycles of oxygen, nitrogen, and especially carbon. Chemical Oceanography will be valuable to Earth scientists as a guide to topics in chemical oceanography, to specialists as a source of detailed information, and to students as a textbook chock full of stimulating problems and provocative topics for discussion.' Michael Bender, Princeton University 'This new book is a comprehensive and modern treatment of a broad range of marine chemistry topics. The thoughtful, well-written text and clear illustrations are a valuable resource for professors, and provide a strong foundation in the subject for advanced undergraduate and graduate students.'
