Fig. 2. Typical GPR profiles: common offset GPR profiles for minimum and maximum active layer thickness on swamp meadow (a, b), GPR velocity profile for the minimum active layer thickness on alpine desert (c) and GPR velocity profile for the maximum active layer thickness on alpine steppe (d) (The red mark line in common offset GPR profiles and the vertex of the black parabola in GPR velocity profiles represent the interpretation depth of the active layer, respectively) |
