Monitoring of active layer dynamics at a permafrost site on Svalbard using multi-channel ground-penetrating radar.

The article assesses the active layer dynamics at the high-arctic continuous permafrost site in Svalbard, Norway. It tackles the thaw depths inferred from non-invasive multi-channel ground-penetrating radar (GPR). It also evaluates the average volumetric soil water content and presents the estimation of the sensible heat content of the soil.
