Biogenic Trace Gases: Measuring Emissions from Soil and Water
Trace gases are those that are present in the atmosphere at relatively low concentrations. Small changes in their concentrations can have profound implications for major atmospheric fluxes, and thereore, can be used as indicators in studies of global change, global biogeochemical cycling and global warming. This new how-to guide will detail the concepts and techniques involved in the detection and measurement of trace gases, and the impact they have on ecological studies. Introductory...

Trace gases are those that are present in the atmosphere at relatively low concentrations. Small changes in their concentrations can have profound implications for major atmospheric fluxes, and thereore, can be used as indicators in studies of global change, global biogeochemical cycling and global warming. This new how-to guide will detail the concepts and techniques involved in the detection and measurement of trace gases, and the impact they have on ecological studies. Introductory chapters look at the role of trace gases in global cycles, while later chapters go on to consider techniques for the measurement of gases in various environments and at a range of scales. A how-to guide for measuring atmospheric trace gases. Techniques described are of value in addressing current concerns over global climate change. Booknews Explains methods for measurement of trace gas exchange, current and future analytic methods, and modeling and extrapolation approaches for describing processes and fluxes across a range of spatial and temporal scales. Topics include trace gas exchange in freshwater and coastal marine environments, micrometeorological techniques, and the use of isotopes in the study of trace gases in terrestrial environments. For atmospheric scientists and other professionals interested in the study of biosphere-atmosphere trace gas exchange. Annotation c. Book News, Inc., Portland, OR (booknews.com)
