Circumpolar distribution and carbon storage of thermokarst landscapes [PDF]
Nature Communications, 2016 In thermokarst landscapes, permafrost thaw causes land subsidence with impacts on hydrology, ecology and biogeochemistry. Here, Olefeldt et al. produce circumpolar maps of thermokarst distribution, identifying that they cover 20% of the northern ...

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 ...

Methane emissions from thermokarst lakes must emphasize the ice-melting impact on the Tibetan Plateau [PDF]
Nature CommunicationsThermokarst lakes, serving as significant sources of methane (CH4), play a crucial role in affecting the feedback of permafrost carbon cycle to global warming.

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.

Respiration of aged soil carbon during fall in permafrost peatlands enhanced by active layer deepening following wildfire but limited following thermokarst [PDF]
Environmental Research Letters, 2018 Permafrost peatlands store globally significant amounts of soil organic carbon (SOC) that may be vulnerable to climate change. Permafrost thaw exposes deeper, older SOC to microbial activity, but SOC vulnerability to mineralization and release as carbon ...

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 ...

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

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.

Onshore Thermokarst Primes Subsea Permafrost Degradation [PDF]
Geophysical Research Letters, 2021 AbstractThe response of permafrost to marine submergence can vary between ice‐rich late Pleistocene deposits and the thermokarst basins that thawed out during the Holocene. We hypothesize that inundated Alases offshore thaw faster than submerged Yedoma.

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 ...
