Theme IV. Chemical, physical and biological characteristics of peat
Protection of peatlands in their function as storage for carbon requires information about their current state, especially about peat condition (degree of decomposition) and thickness. To test for the potential of non-invasive geoelectrical techniques, particularly the measurement of electrical conductivity (EC), we analyzed electrical properties of fen-peat- and the underlying gyttja substrates in the laboratory. Our results show significant differences between EC of peat and gyttja substrate. Additionally, the relationship of EC and water content seems to be controlled by substrate type, such as peat and gyttja material in general, and between different stages of peat decomposition in particular.
