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 ...

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.

A fully automatic framework for sub-pixel mapping of thermokarst lakes using Sentinel-2 images
Science of Remote Sensing, 2023 Mapping and monitoring thermokarst lakes are crucial to understanding the impact of climate change on permafrost regions and quantifying permafrost-related carbon emissions. Several automatic methods based on remote sensing images have been developed for

Abrupt permafrost thaw accelerates carbon dioxide and methane release at a tussock tundra site
Arctic, Antarctic, and Alpine Research, 2022 Abrupt thaw could cause permafrost ecosystems to release more carbon than is predicted from gradual thaw alone. However, thermokarst feature mapping is limited in scope, and observed responses of carbon fluxes to abrupt thaw are variable.

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 ...
