Exchange of trace gases between terrestrial ecosystems and the atmosphere.
Techniques for the measurement of CH4
fluxes from (or to) soils, sediments, and the digestive tract of animals and humans are reviewed. The most frequently employed technique in soilsoilSubject Category: Miscellaneous

/sediment studies is the closed (static) chamber (box) technique. Open chambers are primarily used in animal studies. High areal and temporal variations of CH4
flux rates (over 5 orders of magnitude) have been found in wetland environments; therefore, comparative and continuous measurements are required to obtain reliable average flux rates. From the data presently available, biogenic CH4
from natural wetlands, rice paddies, and ruminants represents the predominant global source for atmospheric CH4
