Description / Table of Contents:
Marine geochemistry offers a fully comprehensive and integrated treatment of the chemistry of the oceans, their sediments and biota. It addresses the fundamental question, 'How do the oceans work as a chemical system?' and it capitalizes on the significant advances in understanding achieved in the past two decades, advances facilitated by improved sampling and analytical techniques, better theoretical concepts, and the establishment of large-scale international oceanographic programmes. Designed for use as a text, the book treats the oceans as a 'unified system' in which material stored in the sea water, the sediment and the rock reservoirs interact to control the composition of sea water itself. Part 1 covers the transport of materials to the oceans via rivers, the atmosphere and hydrothermal systems, and discusses their relative flux magnitudes. Part 2 considers the oceans as a reservoir, introducing water-column parameters before discussing dissolved gases, nutrients and organic carbon, particulate matter, trace elements, down-column fluxes and the benthic boundary layer. Part 3 is devoted to the sediment reservoir. The topics covered include diagenesis, the major components of the sediments, and the processes controlling the geochemistry of oceanic deposits, which are discussed in terms of sediment-forming signals. Part 4 offers an overview and synthesis of the integrated marine geochemical system. Intermediate and advanced students of chemical oceanography and marine geochemistry will welcome this comprehensive text. All other students of the earth sciences will find it to be an essential reference source dealing with the interaction between atmosphere, ocean and solid earth.
