Research Progress on Effects of Thermokarst Lakes on Soil Carbon and Microbial Community [PDF]

open access: yesShuitu baochi tongbao, 2022
[Objective] The impacts of thermokarst lakes formed by rapid thawing and collapsing of permafrost on soil carbon and microorganisms were studied in order to provide a reference for the study of ecological environment and greenhouse gas emissions in such ...

Spatial analyses of thermokarst lakes and basins in Yedoma landscapes of the Lena Delta [PDF]

open access: yesThe 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.

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

open access: yesFEMS 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 ...

Mapping thermokarst lakes in different physical states on the central Tibetan plateau [PDF]

open access: yesInternational Journal of Digital Earth, 2023
Mapping and monitoring the spatial–temporal evolution of thermokarst lakes on the Tibetan Plateau can significantly contribute to the estimation of climate change impacts on permafrost degradation.

Assessing the influence of lake and watershed attributes on snowmelt bypass at thermokarst lakes [PDF]

open access: yesHydrology 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.

Arctic Thermokarst Lakes – Carbon Comes and Goes [PDF]

open access: yes
This PhD project focused on the physical and biogeochemical variability of Arctic thermokarst lake sediments and the resulting impact on the greenhouse gas (GHG) emissions of these lakes. A better understanding of this topic is of importance because thermokarst lakes induce large-scale erosion of sediment organic carbon (SOC) along their shorelines ...

Estimating nutrient stoichiometry and cascading influences on plankton in thermokarst lakes on the Qinghai-Tibet Plateau [PDF]

open access: yesCommunications Earth & Environment
Thermokarst lakes play a critical role in global biogeochemistry. Here we delved into nutrient stoichiometry and its cascading effects on plankton communities across thermokarst lakes on the Qinghai-Tibet Plateau.

Thermokarst lakes disturb the permafrost structure and stimulate through-talik formation in the Qinghai–Tibet Plateau, China: a hydrogeophysical investigation [PDF]

open access: yesThe Cryosphere
Thermokarst lakes are widely distributed in the Qinghai–Tibet Plateau (QTP) and continuously disturb the permafrost structure. Investigating the permafrost and sublake talik structures is crucial to assessing and predicting the fate of the ecosystem and ...

Dissolved organic carbon in thermokarst lakes [PDF]

open access: yes
The Arctic is warming faster compared to other regions on Earth, resulting in significant permafrost thaw, a process that causes the release of stored organic carbon into aquatic systems, particularly thermokarst lakes. These dynamic systems, formed by the degradation of ice-rich permafrost, play an important role in the global carbon cycle.

Thermokarst lake drainage halves the temperature sensitivity of CH4 release on the Qinghai-Tibet Plateau [PDF]

open access: yesNature Communications
Thermokarst lakes as hot spots of methane (CH4) release are crucial for predicting permafrost carbon feedback to global warming. These lakes are suffering from serious drainage events, however, the impacts of lake drainage on CH4 release remain unclear ...
