Biogeochemical Distinctiveness of Peatland Ponds, Thermokarst Waterbodies, and Lakes
Geophysical Research Letters, 2022 AbstractSmall lentic freshwater ecosystems play a disproportionate role in global biogeochemical cycles by processing large amounts of carbon (C), nitrogen (N), and phosphorus (P), but it is unlikely that they behave as one homogenous group for the purpose of extrapolation. Here, we synthesize biogeochemical data from >12,000 geographically distinct

Thermokarst lake waters across the permafrost zones of western Siberia [PDF]
The Cryosphere, 2014 This work describes the hydrochemical composition of thermokarst lake and pond ecosystems, which are observed in various sizes with different degrees of permafrost influence and are located in the northern part of western Siberia within the continuous ...

High carbon emissions from thermokarst lakes of Western Siberia. [PDF]
Nat Commun, 2019 AbstractThe Western Siberia Lowland (WSL), the world’s largest permafrost peatland, is of importance for understanding the high-latitude carbon (C) cycle and its response to climate change. Warming temperatures increase permafrost thaw and production of greenhouse gases.

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

Roles of Thermokarst Lakes in a Warming World [PDF]
Trends in Microbiology, 2020 Permafrost covers a quarter of the northern hemisphere land surface and contains twice the amount of carbon that is currently present in the atmosphere. Future climate change is expected to reduce its near-surface cover by over 90% by the end of the 21st century, leading to thermokarst lake formation.

Research Progress on Effects of Thermokarst Lakes on Soil Carbon and Microbial Community
Shuitu 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 ...

Remote Sensing, 2023 The rapidly warming climate on the Qinghai–Tibet Plateau (QTP) leads to permafrost degradation, and the thawing of ice-rich permafrost induces land subsidence to facilitate the development of thermokarst lakes.

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.

Frontiers in Ecology and Evolution, 2022 Thermokarst lakes are formed following ice-rich permafrost thaw and widely distribute in the cold regions with high latitude and elevation. However, the micro-eukaryotic communities (MECs) in thermokarst lakes are not well studied.

Mapping thermokarst lakes in different physical states on the central Tibetan plateau
International 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.
