Impact of Meteorological Factors on Thermokarst Lake Changes in the Beilu River Basin, Qinghai-Tibet Plateau, China (2000–2016) [PDF]

Water (Switzerland), 2021
Variations in weather conditions have a significant impact on thermokarst lakes, such as the sub-lake permafrost thawing caused by global warming. Based on the analysis of Landsat sensor images by ENVI TM 5.3 software, the present study quantitatively ...

The importance of anaerobic oxidation of methane in thermokarst lakes

2023
About 40% of the annual methane emissions originate from natural, non-anthropogenic sources. These include mainly freshwater sediments, in which significant increase in methane emissions has been observed throughout the past decades with the ongoing global temperature rise.

Patterns and drivers of anaerobic nitrogen transformations in sediments of thermokarst lakes

Global Change Biology, 2023
AbstractSignificant attention has been given to the way in which the soil nitrogen (N) cycle responds to permafrost thaw in recent years, yet little is known about anaerobic N transformations in thermokarst lakes, which account for more than one‐third of thermokarst landforms across permafrost regions.

Stochastic Modelling of Thermokarst Lakes

Thermokarst lakes are widespread and dynamic features of ice-rich permafrost landscapes. They accelerate permafrost thaw, enhance methane production, and alter soil hydrology as well as energy and water exchanges between land and atmosphere. These effects can alter local and global climate.

Lakes as geoindicators of thermokarst landscape changes following wildfires

Environmental Monitoring and Assessment
Rapid landscape changes in the Arctic are occurring at an accelerated rate. The most common disturbances that cover the largest areas of the Arctic are wildfires. It is well known that lakes serve as a good proxy for identifying thermokarst processes. However, the impact of fires is often overlooked in analyses of lake dynamics.
