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.

Circumpolar distribution and carbon storage of thermokarst landscapes [PDF]
Nature Communications, 2016 AbstractThermokarst is the process whereby the thawing of ice-rich permafrost ground causes land subsidence, resulting in development of distinctive landforms. Accelerated thermokarst due to climate change will damage infrastructure, but also impact hydrology, ecology and biogeochemistry. Here, we present a circumpolar assessment of the distribution of

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 Response of Soil Respiration to Temperature and Humidity in the Thermokarst Depression Zone of the Headwater Wetlands of Qinghai Lake [PDF]
BiologyAs the climate warms, the thickening of the active layer of permafrost has led to permafrost melting and surface collapse, forming thermokarst landforms.

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

Legacy permafrost conditions limit deep carbon decomposition in thermokarst peatlands and ponds
Communications Earth & EnvironmentThermokarst fens and ponds form following thaw in permafrost peatland complexes and can release large but poorly constrained quantities of permafrost carbon to the atmosphere.

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

Patterns and persistence of hydrologic carbon and nutrient export from collapsing upland permafrost [PDF]
Biogeosciences, 2015 As high latitudes warm, vast stocks of carbon and nitrogen stored in permafrost will become available for transport to aquatic ecosystems. While there is a growing understanding of the potential effects of permafrost collapse (thermokarst) on aquatic ...
