Key Points

The aim is to evaluate how measurement conditions affect data quality and to characterize the electrical properties in peatlands.
Conducted electrical impedance spectroscopy (EIS) in vertical sounding configuration at four peat sites in Austria.
Analyzed frequency-dependent apparent specific resistivity spectra using Cole-Cole models.
Identified systematic differences in electrical behavior between various peatland types.
EIS revealed vertical changes in electrical properties, differentiating shallow layers from deeper peat based on resistance and phase response.
Notable lateral variability in electrical properties linked to peat type, hydrological regime, and disturbance history.
Frequency-dependent parameters provided enhanced insights into the biogeochemical state of the peat.

Answers are grounded in this paper and cite their sources.

Evaluates electrical properties in peatlands, suggesting EIS enhances underground characterization.
