Permafrost region subsurface organic carbon (OC) pools are a major component of the terrestrial carbon cycle and vulnerable to a warming climate. Thermokarst lagoons are an important transition stage with complex depositional histories during which permafrost and lacustrine carbon pools are transformed along eroding Arctic coasts.

Advances in Thermokarst Research
Permafrost and Periglacial Processes, 2013ABSTRACTThe term thermokarst describes the processes and landforms that involve collapse of the land surface as a result of the melting of ground ice. We review the literature that has contributed to our understanding of patterns, processes and feedbacks, and the environmental consequences of thermokarst, focusing on hillslope, thaw lake and wetland ...

Alaskan Thermokarst Terrain and Possible Martian Analog
Science, 1975A first-order analog to martian fretted terrain has been recognized on enhanced, ERTS-1 (Earth Resources Technology Satellite) imagery of Alaskan Arctic thermokarst terrain. The Alaskan analog displays flat-floored valleys and intervalley uplands characteristic of fretted terrain.

Altered microbial structure and function after thermokarst formation
Global Change Biology, 2020AbstractPermafrost thaw could induce substantial carbon (C) emissions to the atmosphere, and thus trigger a positive feedback to climate warming. As the engine of biogeochemical cycling, soil microorganisms exert a critical role in mediating the direction and strength of permafrost C‐climate feedback.

Outwash Plains and Thermokarst on Mars
Icarus, 1995Abstract The spatial distribution of different types of rampart craters on Mars suggests a hemispheric asymmetry in the distribution of ground ice. The northern plains, especially major topographic depressions near the terminations of outflow channels, have high percentages of rampart craters.

THERMOKARST IN THE EASTERN VERKHOYANSK MOUNTAINS
Vestnik of North-Eastern Federal University. Series "Earth Sciences", 2019В статье говорится о геокриологических исследованиях, проведённых в северо-восточной части Верхоянского хребта представленного хребтами Орулган, Кулар и Кисилях. Для этого региона характерны суровые климатические условия, сплошное развитие низкотемпературной толщи мёрзлых пород, что благоприятствует распространению подземных льдов. Не смотря на широкое

Lakes as geoindicators of thermokarst landscape changes following wildfires
Environmental Monitoring and AssessmentRapid landscape changes in the Arctic are occurring at an accelerated rate. The most common disturbances that cover the largest areas of the Arctic are wildfires. It is well known that lakes serve as a good proxy for identifying thermokarst processes. However, the impact of fires is often overlooked in analyses of lake dynamics.

Stochastic modelling of thermokarst lake distributions
Thermokarst lakes are among the most common and dynamic landscape features in ice-rich permafrost regions. They form due to melting of ground ice and subsequent ground subsidence. Their presence and dynamic behavior do not only influence the carbon exchange with the atmosphere by accelerating permafrost thaw and facilitating the production of methane ...Constanze Reinken +4 more
