The top leftmap shows the location of the study area (Khanovey railway station, close to Vorkuta city) in the NE European Russian Arctic, along with the percentage of permafrost lateral continuity in the region (according to the classification of Brown et al., 1997). The map at the center of the figure shows the survey location area, with the position of boreholes and geophysical data used in this study. The profile positions of the geoelectric surveys performed in 2019 in Site 1A and Site 1B are highlighted in blow-ups on the right. Maps compiled using ArcGis® (Esri) software. Datum: WGS84; projection: UTM 41N. Satellite base image (Gis layer “World Imagery”) and permafrost extent (Gis layer “North Hemisphere Permafrost_WFL1”) were retrieved in 2019 from the ArcGis online database resources.
