“…This is because one type of observation (for example, geothermal or hydrological monitoring) alone does not provide unequivocal conclusions regarding the direction and intensity of future cryosphere changes [17,47]. As such, different multidirectional reactions of ground temperature to local meteorological conditions were observed at two boreholes discussed in the results (Sopka and GP2); similar findings are presented for the East Siberian taiga region in [48].…”

This research presents a comprehensive environmental assessment of a small mountain permafrost catchment of the Anmangynda River in the Upper Kolyma Highland (Northeastern Asia) over the period of 2021–2023. The study reveals significant diversity in climatic, geocryological, and hydrogeological conditions within this confined area, emphasizing the need for extensive field data collection and monitoring in vast permafrost regions with limited data availability. Key findings include variations in ground temperature, maximum seasonal thaw depth, and depths of zero annual amplitudes of ground temperature at different elevations and landscape types. Groundwater and surface flow dynamics within spring aufeis basins exhibit complex geocryological regimes influenced by icing processes. The presence of aufeis and its impact on local hydrology highlight the ecological significance of this phenomenon. Future research should focus on long-term trends in permafrost dynamics and their relationship with climate change, as well as the ecological effects of aufeis formation on local ecosystems. The study underscores the importance of a multi-faceted approach to environmental assessment, incorporating various environmental parameters and processes, to gain a comprehensive understanding of the intricate interactions within the cryosphere and their responses to changing climate conditions. Such knowledge is essential for addressing broader questions related to climate change, ecosystem resilience, and sustainable resource management in Northeastern Siberia.

“…In loamy soils underlain by permafrost in poor drainage conditions, warming is accompanied by formation of suprapermafrost water. An ice-saturated soil profile requires increased heat consumption for ice-water phase transitions during thawing, which leads to a decrease in the depth of seasonal thawing and a decrease in the heat supply of soils during the warm season [9].…”

The paper summarizes the experience of studying the effect of modern warming on the thawing depth of sandy and loamy soils in the permafrost zone. The definition of soil cryogenesis as a natural process and facies as the end result of soil cryogenesis as a process is given. The effect of soil cryogenesis facies on stress corrosion cracking of gas pipes of the Gazprom system in cold and warm seasons has been studied. It was found that the facies of soil cryogenesis are interconnected by the process of energy and mass exchange. It is shown that in the annual cycle, each facies formed by soil cryogenesis is the basis for the development of stress corrosion cracking of gas pipelines.

This study examines the effects of forest belts on erosion andhydrological conditions, soil moisture reserves, and cellulolytic activity, aswell as their influence on agricultural crop yields on slopes. The researchreveals that forest belts lead to increased snow depth and even distribution,reduced soil freezing, and decreased water erosion risk in catchment areas.Additionally, forest belts enhance moisture reserves in the middle slope byreducing lateral water flow. In comparison to upland areas, the lower andmiddle parts of the slope typically exhibit greater snow depth, reduced soilfreezing, and increased soil moisture. Forest belts also promote highercellulolytic activity in adjacent areas. The study finds that barley yieldsincrease on slopes with forest belts, but buckwheat yields decrease due toexcessive vegetative growth.
