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

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 ...

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.

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 ...

Interaction of thermokarst lake and permafrost in Qinghai-Tibet Plateau
Shui kexue jinzhan, 2022 In order to clarify the interaction of thermokarst lake and permafrost, a water-ice-heat coupling model considering heat conduction and convection processes was established at a typical thermokarst lake area in the Beiluhe Basin.

International Journal of Applied Earth Observations and Geoinformation, 2021 Climate warming has accelerated permafrost degradation over the Qinghai-Tibet Plateau (QTP) over the past several decades. The development of thermokarst landforms is a key indicator of permafrost degradation, while it lacks quantified measurements and ...

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.

Landsat-Based Monitoring of Landscape Dynamics in Arctic Permafrost Region
Journal of Remote Sensing, 2022 Ice-rich permafrost thaws as a result of Arctic warming, and the land surface collapses to form characteristic thermokarst landscapes. Thermokarst landscapes can bring instability to the permafrost layer, affecting regional geomorphology, hydrology, and ...

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.
