Circumpolar distribution and carbon storage of thermokarst landscapes [PDF]
Nature Communications, 2016 In thermokarst landscapes, permafrost thaw causes land subsidence with impacts on hydrology, ecology and biogeochemistry. Here, Olefeldt et al. produce circumpolar maps of thermokarst distribution, identifying that they cover 20% of the northern ...

Thermal effect of thermokarst lake on the permafrost under embankment
Advances in Climate Change Research, 2021 In permafrost regions of the Qinghai-Tibet Plateau, road disaster caused by permafrost degradation cannot be ignored. As a common thermal disaster in permafrost regions, thermokarst lake has serious thermal erosion on permafrost and results in permafrost

Spatial analyses of thermokarst lakes and basins in Yedoma landscapes of the Lena Delta [PDF]
The Cryosphere, 2011 Distinctive periglacial landscapes have formed in late-Pleistocene ice-rich permafrost deposits (Ice Complex) of northern Yakutia, Siberia. Thermokarst lakes and thermokarst basins alternate with ice-rich Yedoma uplands.

Role of methanotrophy in a high‐methane emitting thermokarst lake
Limnology and Oceanography, Volume 71, Issue 9, September 2026.Abstract Thermokarst (thaw) lakes are projected to be an increasing source of atmospheric methane (CH4), a potent greenhouse gas, as climate warms and permafrost thaws. However, the magnitude of CH4 cycling, particularly the role of aerobic CH4 oxidation (methanotrophy), among thermokarst lakes, is not well constrained.

Tracking lake drainage events and drained lake basin vegetation dynamics across the Arctic [PDF]
Nature Communications, 2023 Widespread lake drainage can lead to large-scale drying in Arctic lake-rich areas, affecting hydrology, ecosystems and permafrost carbon dynamics. To date, the spatio-temporal distribution, driving factors, and post-drainage dynamics of lake drainage ...
