| Abstract | Electrical resistivity tomography (ERT) is a minimally invasive geophysical method that produces a model of subsurface resistivity from a large number of electrical resistance measurements. Strong
resistivity contrasts usually exist between frozen and unfrozen earth materials, making ERT an effective and increasingly utilized tool in permafrost research. In this paper, we review more than 300 scientific publications dating from 2000 to 2022 to
identify the capabilities and limitations of ERT for permafrost applications. The annual publication rate has increased by a factor of 10 over this period, but several unique challenges remain, and best practices for acquiring, processing, and
interpreting ERT data in permafrost environments have not been clearly established. In this paper, we make recommendations for ERT surveys of permafrost and highlight recent advances in the field, with the objective of maximizing the utility of
existing and future surveys. |
| Summary | (Plain Language Summary, not published)
Electrical resistivity tomography (ERT) is a geophysical method that uses measurements of electrical current and voltage to image the subsurface. It is
used in several environmental science disciplines, including the study of permafrost. Over the past two decades, the number of studies reporting on the use of ERT to understand permafrost conditions and their change over time has increased 10-fold.
However, there are several unique challenges related to acquiring, processing, and interpreting ERT data in permafrost environments, and best practices in the field have not been clearly established. We propose a number of recommendations for ERT
surveys of permafrost and highlight recent advances in the field, with the objective of maximizing the utility of existing and future surveys. |
