Opis

Marine dissolved organic matter (DOM) is a complex mixture of molecules found throughout the world's oceans. It plays a key role in the export, distribution, and sequestration of carbon in the oceanic water column, posited to be a source of atmospheric climate regulation. Biogeochemistry of Marine Dissolved Organic Matter, Second Edition, focuses on the chemical constituents of DOM and its biogeochemical, biological, and ecological significance in the global ocean, and provides a single, unique source for the references, information, and informed judgments of the community of marine biogeochemists. Presented by some of the world's leading scientists, this revised edition reports on the major advances in this area and includes new chapters covering the role of DOM in ancient ocean carbon cycles, the long term stability of marine DOM, the biophysical dynamics of DOM, fluvial DOM qualities and fate, and the Mediterranean Sea. Biogeochemistry of Marine Dissolved Organic Matter, Second Edition, is an extremely useful resource that helps people interested in the largest pool of active carbon on the planet (DOC) get a firm grounding on the general paradigms and many of the relevant references on this topic.

• Features up-to-date knowledge of DOM, including five new chapters
• The only published work to synthesize recent research on dissolved organic carbon in the Mediterranean Sea
• Includes chapters that address inputs from freshwater terrestrial DOM

O autorze

Dennis Hansell has conducted research on the biogeochemistry of major elements in the ocean for more than 30 years. His analyses have largely focused on data collected in the conduct of international projects addressing hydrographic and biogeochemical surveys of the global ocean. Questions of particular interest revolve around the role of dissolved organic matter (DOM) in the cycling of marine carbon, such as the accumulation of DOM in the surface ocean, its export to great depth with overturning circulation, its fate upon export, and its introduction to the deep ocean via sinking biogenic particles. This work has been done in all the major ocean basins; thus, the research products lend themselves to furthering understanding of the ocean as a global system. Hansell served as co-editor of the first two editions of this book. Craig Carlson is a Professor in the Department of Ecology, Evolution, and Marine Biology at the University of California, Santa Barbara. For the past three decades Carlson's research interests have been shaped by an interdisciplinary blend of organic biogeochemistry and marine microbial ecology. His research contributions include assessing the dissolved organic matter (DOM) production, removal, and transformation processes in marine systems, providing accurate measurements of DOM inventories, determining the role of DOM export in the biological carbon pump and it's the fate after export within the dark ocean. The overall goal of these research efforts strives to make quantitative links between microbial community dynamics and DOM biogeochemistry in the open sea. Carlson served as co-editor of the first two editions of this book.
