Abstract: Thermokarst lakes cover nearly one fourth of ice-rich permafrost lowlands in the Arctic. Sediments from an athalassic subsaline thermokarst lake on Herschel Island (69°36′N; 139°04′W, Canadian Arctic) were used to understand regional changes in climate… read more here.

DOI: 10.1007/s12665-017-7143-2
Abstract: Thermokarst lake is a significant indicator of permafrost degradation. However, the evaluation of thermokarst lake development is very difficult through physical mechanism analysis because the development is influenced by many factors. In the present study,… read more here.

DOI: 10.1016/j.earscirev.2020.103365
Abstract: Abstract Greenhouse gas emissions from physical permafrost thaw disturbance and subsidence, including the formation and expansion of thermokarst (thaw) lakes, may double the magnitude of the permafrost carbon feedback this century. These processes are not… read more here.

DOI: 10.1029/2017jd027751
Abstract: We conducted eddy covariance measurements from April to August 2014 on a Siberian thermokarst lake. The study site is located in the Lena River Delta and characterized as a floating ice lake. Heat fluxes differed… read more here.

DOI: 10.1111/1462-2920.14345
Abstract: Summary Arctic permafrost soils store large amounts of organic matter that is sensitive to temperature increases and subsequent microbial degradation to methane (CH 4 ) and carbon dioxide (CO 2 ). Here, we studied methanogenic… read more here.

DOI: 10.1111/gcb.16151
Abstract: Methane (CH4) release to the atmosphere from thawing permafrost contributes significantly to global CH4 emissions. However, constraining the effects of thaw that control the production and emission of CH4 is needed to anticipate future Arctic… read more here.
