investigations in permafrost regions demonstrate that ground-penetrating radar (GPR) offers an effective way to measure these parameters at a scale appropriate for many process and geotechnical studies. The AA. discuss the fundamental properties of GPR and how
Three important parameters that need to be quantified for many permafrost studies are the location of ice in the ground, the position of thermal interfaces, and spatial variations of the water content in the active layer. The data from over 100
those properties make it suitable for use in permafrost studies using a radar stratigraphic approach and highlight specific applications with case studies.
