Unravelling methylmercury formation in high-altitude Tibetan thermokarst lakes
Journal of Hazardous MaterialsClimate warming accelerates permafrost degradation, which not only increases greenhouse gas emission but also the conversion of permafrost-stored mercury (Hg) to the neurotoxic methylmercury (MeHg) - a global pollutant to humans and ecosystems. While several studies have examined Hg transformation processes in high-latitude Arctic permafrost, little is

Thermokarst lake to lagoon transitions in Eastern Siberia
2020As 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 EnvironmentThe 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, 2016A 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.
