A synthesis of methane dynamics in thermokarst lake environments [PDF]
Earth-Science Reviews, 2020 Abstract Greenhouse gas emissions from physical permafrost thaw disturbance and subsidence, including the formation and expansion of thermokarst (thaw) lakes, may double the magnitude of the permafrost carbon feedback this century. These processes are not accounted for in current global climate models.

A Tale of Two Seasons: Distinct Seasonal Viral Communities in a Thermokarst Lake [PDF]
Microorganisms, 2023 Thermokarst lakes are important features of subarctic landscapes and are a substantial source of greenhouse gases, although the extent of gas produced varies seasonally. Microbial communities are responsible for the production of methane and CO2 but the “

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

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 ...

The Role of Thermokarst Lake Expansion in Altering the Microbial Community and Methane Cycling in Beiluhe Basin on Tibetan Plateau [PDF]
Microorganisms, 2022 One of the most significant environmental changes across the Tibetan Plateau (TP) is the rapid lake expansion. The expansion of thermokarst lakes affects the global biogeochemical cycles and local climate regulation by rising levels, expanding area, and ...

Thermokarst-lake methanogenesis along a complete talik profile [PDF]
Biogeosciences, 2015 Abstract. Thermokarst (thaw) lakes emit methane (CH4) to the atmosphere formed from thawed permafrost organic matter (OM), but the relative magnitude of CH4 production in surface lake sediments vs. deeper thawed permafrost horizons is not well understood.

Assessing the influence of lake and watershed attributes on snowmelt bypass at thermokarst lakes [PDF]
Hydrology and Earth System Sciences, 2022 Snow represents the largest potential source of water for thermokarst lakes, but the runoff generated by snowmelt (freshet) can flow beneath lake ice and via the outlet without mixing with and replacing pre-snowmelt lake water.

A new Stefan equation to characterize the evolution of thermokarst lake and talik geometry [PDF]
The Cryosphere, 2022 Thermokarst lake dynamics, which play an essential role in carbon release due to permafrost thaw, are affected by various geomorphological processes. In this study, we derive a three-dimensional (3D) Stefan equation to characterize talik geometry under a

Evolution of a High-Mountain Thermokarst Lake in the Swiss Alps [PDF]
Arctic, Antarctic, and Alpine Research, 2001 Thermokarst lakes, a characteristic landscape element of the Arctic, are rarely found outside arctic situations. Here, a 30-yr photogrammetric monitoring series of a thermokarst lake in the Gruben area, Swiss Alps, is presented. The lake, situated in an environment of dead-ice remains and creeping permafrost, reached a final size of ca.
