Water tracks in the lower Lena River basin [PDF]
E3S 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.

Establishment of Permafrost Thermal Monitoring Sites in East Siberia
Land, 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 ...

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

Nature 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.

Proceedings of the National Academy of Sciences, 2013 Last October, when Susan Hubbard and her team pulled sleds full of sensitive sensors across the snow near the northernmost point in Alaska, temperatures hovered in the single digits and low teens (e.g., 8–15 °F). Foremost in the researchers’ minds, aside from collecting data on the frozen ground beneath their feet, were two things: keep an eye out for ...

Heavy and Light Mineral Association of Late Quaternary Permafrost Deposits in Northeastern Siberia
Frontiers in Earth Science, 2022 We studied heavy and light mineral associations from two grain-size fractions (63–125 μm, 125–250 µm) from 18 permafrost sites in the northern Siberian Arctic in order to differentiate local versus regional source areas of permafrost aggradation on the ...
