Additional equipment

To model gas fluxes of CO2 and CH4 we are logging soil temperatures in 5, 10, 20 and 50 cm year around, soil moisture in 10cm and measure manually groundwater levels at each collar.

One pathway of CH₄ might be ebullition. To detect gas bubble growth inside the peat it is planned to log changes of volumetric water content using time domain reflectrometry (TDR) (cp. Kellner et al. 2005). Large scale eflux of gas bubbles might influence peat surface hights. We try to detect these fluctuations with surface level recorders and squishometers (cp. Kellner et al. 2005).
