Description :
The moisture content of the moss layer affects the thermal insulative capacity and preservation of permafrost. It also controls the growth and collapse history of palsas and other peat mounds, and is relevant in general terms, to permafrost thaw (thermokarst). In this study, the AA. evaluate new soil moisture probes in Sphagnum moss under laboratory conditions. They test and calibrate 7 different soil moisture sensors. Each sensor has a unique response to changing moisture content levels, solution salinity, moss bulk density and to the orientation (structure) of the Sphagnum relative to the sensor. The AA. provide polynomial equations for dead and live Sphagnum moss.
