Thermokarst lakes are characteristic landscape features in Arctic permafrost regions and are relevant emitters of the greenhouse gas methane (Walter et al., 2006). A major pathway for methane emissions from these lakes is through bubbling (ebullition) from discrete seeps. An accurate assessment of t...
