High resolution seismic and ground penetrating radar-geophysical profiling of a thermokarst lake in the western Lena Delta, Northern Siberia [PDF]
, 2002 High resolution seismic and ground-penetrating radar (GPR) have been acquired over Lake Nikolay in the western Lena Delta (Siberia) in order to study the uppermost basin fill and the bordering frozen margins. GPR measurements were completed on the frozen

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.

Thermokarst lake detection : a remote sensing approach [PDF]
Rock glaciers are apparent occurrences, and thus indicators of permafrost conditions in mountain regions. Active rock glaciers contain ice and are moving, while inactive rock glaciers are immobile but still contain ice. They can be summarized as intact rock glaciers.

A new Stefan equation to characterize the evolution of thermokarst lake and talik geometry [PDF]
The Cryosphere, 2022 Thermokarst lake dynamics, which play an essential role in carbon release due to permafrost thaw, are affected by various geomorphological processes. In this study, we derive a three-dimensional (3D) Stefan equation to characterize talik geometry under a

Grain size distribution of sediment core PG2412 beneath thermokarst lake Goltsovoye Lake on the Bykovsky Pensinula, northeastern Siberia [PDF]
, 2020 These datasets describe a 31.5 m long sediment core taken from beneath thermokarst lake Goltsovoye Lake (71.74515 N, 129.30217 E) on the Bykovsky Peninsula, northeastern Siberia. The thermokarst lake was 510 cm deep.

(Table 3) Changes in thermokarst lake extent, infilling with fen vegetation and lateral erosion at study sites in Canada, Russia and Sweden [PDF]
, 2011 Thermokarst lakes = surrounded by peat plateau along >75% of the shoreline. For all study sites the changes in lake area were statistically significant (p < 0.001), except for in the 2 km × 2 km area in Rogovaya (p = 0.63).

Decadal-scale hotspot methane ebullition within lakes following abrupt permafrost thaw
Environmental Research Letters, 2021 Thermokarst lakes accelerate deep permafrost thaw and the mobilization of previously frozen soil organic carbon. This leads to microbial decomposition and large releases of carbon dioxide (CO _2 ) and methane (CH _4 ) that enhance climate warming ...

The evolution of a thermokarst-lake landscape: late Quaternary permafrost degradation and stabilization in interior Alaska [PDF]
, 2016 Thermokarst processes characterize a variety of ice-rich permafrost terrains and often lead to lake formation. The long-term evolution of thermokarst landscapes and the stability and longevity of lakes depend upon climate, vegetation and ground ...
