The Evolution of Methane Emissions in Thermokarst Lakes  

Thermokarst lakes, formed by permafrost thaw in the Arctic, are ubiquitous with abrupt permafrost thaw and large atmospheric source "hotspots" of methane (CH4) and carbon dioxide (CO2) emissions, which are expected to double permafrost carbon emissions by the end of the century.

Thermokarst lake to lagoon transitions in Eastern Siberia

2020
As the Arctic coast erodes, it drains thermokarst lakes, transforming them into lagoons, and, eventually, integrates them into subsea permafrost. Lagoons represent the first stage of a thermokarst lake transition to a marine setting and possibly more saline and colder upper boundary conditions.

Investigating effects of thermokarst lakes on permafrost under equilibrium conditions

Science of The Total Environment
The degradation of permafrost due to climate change has significant effects on the hydrological processes and ecosystems in arctic and subarctic regions. Thermokarst lakes, formed from permafrost thaw and subsidence, play a crucial role in this process by influencing heat storage and exchange and accelerating the thaw rate of the surrounding permafrost.

On the thermal influence of thermokarst lakes on the subsea permafrost evolution

SPIE Proceedings, 2016
A one-dimensional model for the heat transfer with a phase change is proposed to simulate the dynamics of the subsea permafrost on the Laptev Sea shelf. By now we investigate the evolution of the subsea permafrost since the last glacial maximum, taking into account a possible development of the thermokarst lakes.

Dissolved organic carbon in thermokarst lakes

The Arctic is warming faster compared to other regions on Earth, resulting in significant permafrost thaw, a process that causes the release of stored organic carbon into aquatic systems, particularly thermokarst lakes. These dynamic systems, formed by the degradation of ice-rich permafrost, play an important role in the global carbon cycle.
