Accelerating thermokarst lake changes on the Qinghai–Tibetan Plateau [PDF]

Scientific Reports
As significant evidence of ice-rich permafrost degradation due to climate warming, thermokarst lake was developing and undergoing substantial changes. Thermokarst lake was an essential ecosystem component, which significantly impacted the global carbon ...

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

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 “

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 ...

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.

Chemoautotrophic carbon fixation in thermokarst lakes on the Tibetan Plateau. [PDF]

Nat Commun
Dissolved organic carbon (DOC) derived from thermokarst lakes is usually considered to be prone to microbial degradation and releases substantial carbon dioxide to the atmosphere, potentially enhancing the positive permafrost carbon (C)-climate feedback.

Methane emissions from thermokarst lakes must emphasize the ice-melting impact on the Tibetan Plateau [PDF]

Nature Communications
Thermokarst lakes, serving as significant sources of methane (CH4), play a crucial role in affecting the feedback of permafrost carbon cycle to global warming.

Microbial assemblages in Arctic coastal thermokarst lakes and lagoons. [PDF]

FEMS Microbiol Ecol
Abstract Several studies have investigated changes in microbial community composition in thawing permafrost landscapes, but microbial assemblages in the transient ecosystems of the Arctic coastline remain poorly understood. Thermokarst lakes, abrupt permafrost thaw features, are widespread along the pan-Arctic coast and transform into ...

Stochastic modelling of thermokarst lakes: size distributions and dynamic regimes [PDF]

The Cryosphere
Thermokarst lakes are among the most common and dynamic landscape features in ice-rich lowland permafrost regions. They influence carbon, water and energy fluxes between atmosphere and land surface, and are an important component of Arctic lowland ...
