ERT datasets of the article "Life cycles and polycyclicity of mega retrogressive thaw slumps in arctic permafrost revealed by 2D/3D geophysical and long-term retreat monitoring"

This data set provides electrical resistivity tomography (ERT) data related to the article "Life cycles and polycyclicity of mega retrogressive thaw slumps in arctic permafrost revealed by 2D/3D geophysical and long-term retreat monitoring" on Herschel Island, Canada starting in 2011. For each ERT profile presented in the paper, we include two raw data files: an apparent resistivity text file and a coordinate/topography text file. The apparent resistivity text file shows each quadrapole configuration, the position (in meters) of the current (C) and potential (P) electrodes, and the apparent resistivity (in ohm-m). The coordinate/topography files contain the elevation (in meters) associated with each survey position (in meters), as well the latitude and longitude of the survey start and end points. For all files, the position refers to surface distance (not true horizontal distance). The text files are named according to the figure caption. For Figure 12 (containing seven ERT profiles parallel to the coastline at slump D), the filenames contain a distance value (e.g., 15 m), indicating that the survey was carried out 15 m away from the coastline.      «
