Abstract

A typical deep thermokarst was studied in the Beiluhe Basin. Lakeshore retrogression, water temperatures, and ground temperatures beneath and around the lake were monitored. About 80% of the lakeshore edge collapsed each year with a maximum rate of about 1.8 m from August 2007 to October 2008. The warm season was the main period of shoreline collapse, especially from August to October. Overall, the high degree of disturbance associated with the thermokarst lake is shown by mean annual ground temperatures beneath it that are more than 5°c higher than in the surrounding terrain at the same depth
