Summary
Summary
Since 1980 a considerable amount of scientific research dealing with geochemical processes in marine sediments has been carried out. This textbook summarizes the state of the art in this field of research. The topics comprise the examination of sedimentological and physical properties of the sedimentary solid phase, of pore water and pore water constituents, organic matter as the driving force of most microbiological processes, biotic and abiotic redox reactions, carbonates and stable isotopes as proxies for paleoclimate reconstruction, metal enrichments in ferromanganese nodules and crusts as well as in hot vents and cold seeps on the seafloor. A new chapter describes properties, occurrence and formation of gas hydrates in marine sediments. The textbook ends with a chapter on model conceptions and computer models to quantify processes of early diagenesis.

Choice Review
Marine geochemistry is an interdisciplinary topic; here, the editors have assembled chapters covering the range of disciplines and subjects, with one exception: chemistry of the marine microlayer. The book's 14 chapters summarize sources and materials in the marine environment; physical and magnetic properties of sediment; theoretical and practical aspects of pore water biogeochemistry; cycling and early diagenesis of water column and sedimentary organic matter; microbes in marine biogeochemistry, which unfortunately assumes a background in microbiology; oxygen and nitrate cycling; iron biogeochemistry with discussions of both iron in surface water productivity and in sedimentary digenesis; sulfate diagenesis, marine carbonates focusing on production, water-column flux, accumulation and destruction; stable isotope geochemistry focusing on original and diagenetic signatures; chemistry of manganese with particular emphasis on nodules and crusts; benthic fluxes illustrating geostatistics and geographical information systems and including a detailed discussion of the quality and comparability of databases; localized inputs at spreading centers (hot vents) and subduction zones (cold seeps); and equilibrium geochemical modeling and coupled transport modeling. Most chapters are well written and have numerous examples, data tables, and excellent figures. For graduate students, researchers, and professionals. N. W. Hinman; University of Montana
