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.

Über Autor(innen)

Emerson, Steven R
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.

Hamme, Roberta C
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.
