Localized Browning in Thermokarst-Dominated Landscapes Reverses Regional Greening Trends Under a Warming Climate in Northeastern Siberia

Remote Sensing
The response of Arctic vegetation to climate warming exhibits pronounced spatial heterogeneity, driven partly by widespread permafrost degradation. However, the role of thermokarst lake development in mediating vegetation-climate interactions remains ...

Terrestrial inputs and in‐lake processes shape dissolved organic matter along a permafrost gradient

Limnology and Oceanography, Volume 71, Issue 11, November 2026.
Abstract Northern permafrost landscapes store large amounts of organic carbon that can enter lakes as dissolved organic matter (DOM), but links among shoreline terrestrial sources, lake‐water DOM composition, and catchment configuration remain uncertain in low‐precipitation Shield landscapes. We combined shoreline soil‐porewater and lake‐water sampling

Simulating thermokarst lakes [PDF]

Eos, Transactions American Geophysical Union, 2012
Thermokarst lakes, which form from thawing permafrost, alter landscapes and hydrology and can release significant amounts of methane to the atmosphere. To learn more about the dynamics of thermokarst lakes, Kessler et al. created a three‐dimensional numerical model of these lakes that includes the surrounding topography.

Contrasting Responses of Carbon Dioxide and Methane Fluxes Following Thermokarst Erosion Across Tundra‐Lake Interfaces in the Western Canadian Arctic

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 11, November 2026.
Abstract Erosion from ice‐rich permafrost thaw (“thermokarst”) alters tundra vegetation cover and soil moisture, and laterally transports organic material into lakes, altering net fluxes of carbon dioxide (FCO2), methane (FCH4), and nitrous oxide (FN2O).

Active thermokarst zones on permafrost territory and their deteсting on space images

Известия Томского политехнического университета: Инжиниринг георесурсов, 2019
The relevance of the paper is caused by the need to develop methods of identifying and mapping the areas of active thermokarst processes on the permafrost territory, based on satellite images and geoinformation technologies in the context of assessing ...

Petagram‐Scale Dissolved Organic Carbon Stocks in Alaskan Permafrost Soils

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract The pan‐Arctic permafrost region hosts vast amounts of soil organic carbon, a pool increasingly susceptible to climate‐driven changes. Dissolved organic carbon (DOC) is a key component of this carbon pool. However, its stocks and fluxes remain poorly understood due to limited measurements and challenges of tracking subsurface fluxes across ...

Deep learning-based detection for thermokarst topography using the chopped picture method

Progress in Earth and Planetary Science
The polar region is sensitive to climate change, with concerns about the effects on ecosystems and human society. In particular, the thawing of permafrost associated with rising temperatures accelerates the microbial decomposition of organic carbon in ...
