Water tracks in the lower Lena River basin [PDF]

open access: yesE3S Web of Conferences, 2020
In the permafrost regions, where water filtration zone is limited by the shallow active layer, the surface flow forms a network of hollows, called «water tracks», oriented along the slope gradient.

Assessing effects of permafrost thaw on C fluxes based on multiyear modeling across a permafrost thaw gradient at Stordalen, Sweden [PDF]

open access: yes, 2014
Northern peatlands in permafrost regions contain a large amount of organic carbon (C) in the soil. Climate warming and associated permafrost degradation are expected to have significant impacts on the C balance of these ecosystems, but the magnitude is ...

Estimation of subsurface porosities and thermal conductivities of polygonal tundra by coupled inversion of electrical resistivity, temperature, and moisture content data [PDF]

open access: yes, 2020
Studies indicate greenhouse gas emissions following permafrost thaw will amplify current rates of atmospheric warming, a process referred to as the permafrost carbon feedback.

Permafrost-Landscape Map of the Republic of Sakha (Yakutia) on a Scale 1:1,500,000

open access: yesGeosciences, 2018
The history of permafrost landscape map compilation is related to the study of ecological problems with permafrost. Permafrost-landscape studies are now widely used in geocryological mapping. Permafrost-landscape classifications and mapping are necessary

Establishment of Permafrost Thermal Monitoring Sites in East Siberia

open access: yesLand, 2020
Permafrost lies close to the surface of the day, therefore, it is able to quickly respond to modern climatic changes. Under these conditions, the goal of understanding the evolution of permafrost in the near future requires monitoring studies of the ...

Thawing permafrost poses environmental threat to thousands of sites with legacy industrial contamination

open access: yesNature Communications, 2023
Thousands of industrial sites were found to be correlated with contaminated sites in the Arctic. Between 13,000 and 20,000 contaminated sites are likely to exist in the permafrost region, 26% of which will be affected by permafrost thaw before 2100.

The influence of particle morphology on the long-term strength of sandy soil under freeze-thaw cycles

open access: yesCase Studies in Construction Materials, 2023
Freeze-thaw weathering can fragment sand and gravel materials, altering their mechanical properties. This study aims to simulate the effects of freeze-thaw weathering by subjecting sand and gravel materials to cycling tests.

Ecological and geochemical characteristics of the snow cover in the Yakutsk city (Central Siberia)

open access: yesЛëд и снег, 2021
For the first time, the geochemistry of snow cover on the territory of the city of Yakutsk, the largest city located in the permafrost zone, is considered on the basis of recent methods of analysis. To study the chemical composition of the snow cover and
