This Seminar will revise ongoing approaches in the investigation of alpine permafrost using geophysical electrical methods and demonstrate the importance of accounting for interfacial conductivity in the case of frozen ground, as presented in Figure 1. Moreover, the seminar will present some of our recent results regarding the application of transient electromagnetic soundings to delineate ice‐rich areas in alpine permafrost. To this end, we propose a stochastic modeling and inversion approach explicitly considering interfacial conductivity that permits us to evaluate the uncertainty of the resulting model parameters.
