Seismic and Electrical Resistivity Datasets for Characterizing Permafrost in Alaska (August 2023)

This dataset consists of Multichannel Analysis of Surface Waves (MASW) and Electrical Resistivity Tomography (ERT) data to examine permafrost variability across a range of disturbed and undisturbed locations and the impact of civil infrastructure on permafrost degradation in Utqiaġvik, Alaska. These geophysical methods allow us to image the sub-surface and understand permafrost properties variation. The results are discussed in the following paper: Tourei, A., Ji, X., Rocha dos Santos, J. F., Czarny, R., Rybakov, S., Wang, Z., Hallissey, M., Martin, E. R., Xiao, M., Zhu, T., Nicolsky, D., Jensen, A. (2023).
