Over the past ten years, a number of new large-scale oceanographic programs have been initiated. These include the Climate Variability Program (CLIVAR) and the recent initiation of the Geochemical Trace Metal Program (GEOTRACES).

An engaging introduction to marine chemistry and the ocean's geochemical interactions with the solid earth and atmosphere, for students of oceanography.
The principles of chemical oceanography provide insight into the processes regulating the marine carbon cycle. The text offers a background in chemical oceanography and a description of how chemical elements in seawater and ocean sediments are used as tracers of physical, biological, chemical and geological processes in the ocean. The first seven chapters present basic topics of thermodynamics, isotope systematics and carbonate chemistry, and explain the influence of life on ocean chemistry and how it has evolved in the recent (glacial-interglacial) past. This is followed by topics essential to understanding the carbon cycle, including organic geochemistry, air-sea gas exchange, diffusion and reaction kinetics, the marine and atmosphere carbon cycle and diagenesis in marine sediments.

Ideal as a textbook for upper-level undergraduates and graduates in oceanography, environmental chemistry, geochemistry and earth science and a valuable reference for researchers in oceanography.
From Harvard University to the University of Miami, the first edition of Chemical Oceanography was a great success as a textbook. Now you can own the fully updated second edition. Each chapter has been expanded and/or updated in accordance with the current state of knowledge about the chemistry of oceans.
Chemical Oceanography, Third Edition, is a survey of essential concepts that contains a wealth of new data and maps, resulting in a more in-depth examination of oceanic biogeochemical processes. The most up-to-date compilation of essential concepts and data available on the subject, this book responds to the need for a thorough, yet straightforward approach to the subject for students, researchers, and other professionals in marine science, geochemistry, and environmental chemistry. The third edition of Chemical Oceanography incorporates significant findings on the properties of oceans from recent, large-scale oceanographic programs and valuable new data derived from additional experiments. It also discusses the interactions of metals with inorganic and natural organic ligands and the effect of speciation of metals on bioavailability and toxicity. The section on carbonate systems now examines the input of fossil fuel CO2 into the ocean and its effect on the pH of the world oceans. Frank J. Millero, a world-renowned marine researcher and professor of undergraduate and graduate courses at the University of Miami for nearly 40 years, presents a time-tested and user-friendly resource specifically designed for both classroom use and self-study.
The accuracy of chemical oceanographic measurements depends on calibration against reference materials to ensure comparability over time and among laboratories. Several key parameters lack reference materials for measurements in seawater, particles in the water column, and sediments. Without reference materials it is difficult to produce the reliable data sets or long-term baseline studies that are essential to verify global change and oceanic stability. Chemical Reference Materials : Setting the Standards for Ocean Science identifies the most urgently required chemical reference materials based on key themes for oceanographic research and provides suggestions as to how they can be developed within realistic cost constraints. Chemical analyses of seawater are uniquely difficult given the poorly known speciation and the low concentration of many of the analytes of interest. Analyses of suspended and sedimentary marine particulate materials present their own distinct challenges, primarily due to potential interference by predominant mineral phases of different types. Of all the analytical methods applied to marine waters and particles, at present only a small fraction can be systematically evaluated via comparison to reference materials that represent the appropriate natural concentrations and matrices. Specifically, the committee was charged with the following tasks: - compile from available sources a list of important oceanographic research questions that may benefit from chemical reference standards; - create a comprehensive list of reference materials currently available for oceanographic studies; - identify and prioritize the reference materials needed to study the identified research questions; - determine for each priority analyte whether reference materials and/or analytic methods should be standardized; and - identify the most appropriate approaches for the development and future production of reference materials for ocean sciences.
