Electrical resistivity tomography (ERT) is a geophysical technique that is often used to characterize and monitor permafrost. Automated ERT (A-ERT) systems enable the collection of temporally dense datasets without the need for repeated site visits. So far, only a few A-ERT systems have been deployed in permafrost environments. We present the results of an A-ERT system installed on King George Island, Antarctica. The system withstood the harsh Antarctic environment and collected resistivity data four times a day for a full year in 2022-2023. Resistivity data captured seasonal freezing and thawing, as well as short-term meteorological events. Resistivity was used to estimate changes in unfrozen water content, and co-located temperature and soil moisture data were used to assess relationships between resistivity, soil moisture, and temperature. This work showcases the ability of A-ERT systems to monitor permafrost and soil moisture dynamics and contributes a unique dataset to global permafrost monitoring efforts.
