Thermokarst lakes cover an estimated 20-40% of Earth’s 14x106 km2 of permafrost. Increasing thermokarst lake size is often used as a proxy for permafrost degradation and associated methane emissions. Lack of long-term, high frequency observations has led to poor quantification of changes in thermoka...
