“…If our assumptions are correct and the permafrost thawing is caused by the groundwater, then the underground leakage can be determined using the electrical resistivity tomography (ERT). The ERT method is successfully used to solve the problems of mapping permafrost, determining the depth of the active layer and tails (You et al 2013;McClymont et al 2013;Yeltsov et al 2017;Olenchenko et al 2019).…”

In the paper, we consider a method of ground temperature monitoring using the thermometric boreholes and computer modeling the residential buildings with the pile foundation in the city of Salekhard; note that it is located in the permafrost zone. Construction of the residential buildings and industrial structures in the permafrost zone and their operation is carried out according to the principle of preserving the frozen state of foundations. For ground temperature monitoring, thermometric boreholes are used. In a given time period, the measured temperatures are transferred to a server for further processing. Information about the temperature is an important factor for the safety of the buildings and it can be used to evaluate the piles bearing capacity. It allows to propose options for the soil thermal stabilization or to eliminate the detected technogenic heat sources. An approach of mathematical modeling to reconstruct the temperature fields in the pile foundation base of a building is discussed taking into account the data of temperature monitoring. 24 boreholes were equipped with more than 400 in-borehole thermal sensors for testing the method under the residential building I. The preliminary modeling is carried out for December and January 2020 for the contact thermal conductivity model with phase transition with the upper part of the geological section typical for Salekhard (the sandy soils). The modeling describes the freezing processes during the months in detail. The thermal monitoring allows to say that the ground in the base of the Residential building I is stable. But there are detected heat transfers near the borehole T1 at the depth of 12–14 m. The combination of monitoring and computer modeling makes it possible to assess the safety of the operation of the residential buildings in cities located in the permafrost zones.

“…Several studies compare different array types and their abilities to resolve permafrost features (e.g., 49–51 ). Some practitioners collected data using multiple array types and amalgamated the data to take advantage of the strengths of each array (e.g., 51 ). In nonpermafrost research, several studies have used nonstandard array types that combine various four‐point measurements to optimize resolution, 52–54 although this is not yet common practice in permafrost research.…”

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.

Taliks are bodies or layers of unfrozen ground in permafrost areas. Recent research on taliks has been driven largely by the potential for release of greenhouse gases as taliks expand, and engineering challenges associated with thawing permafrost. Observations of talik configuration and development have been assisted by advances in geophysical techniques that complement mechanical and thermal measurements. Suprapermafrost taliks have been observed in a range of settings associated with disturbance from wildfire and infrastructure. These features are included in a revised talik classification scheme presented in this paper. Observations of methane release have renewed interest in lake talik initiation and development, resulting in substantial efforts to model thaw lake expansion. Hotspots of methane release have also been identified at saline springs. Recent simulations indicate that groundwater flow can significantly accelerate talik expansion and that incorporating heat advection may be required for accurate transient simulations. Ongoing global warming is expected to exacerbate the effects of surface disturbances on talik development and limit the ability of permafrost to recover in marginal permafrost areas.
