I am a PhD student at the Department of Geological Sciences of Stockholm University. My research focuses on trace gas emissions from lakes in thawing permafrost landscapes that drive climatic changes in the Arctic. I measure emissions of carbon dioxide and methane using gas bubble traps, floating chambers and the eddy covarience method. Uniquely, our monitoring program also includes the ice cover season and spring, when up to 56% of annual carbon emissions take place.

The poster details the results of the two full years of lake methane emission observation. We also present robust temperature-flux relationships based on eight years of ice free season measurements carried out by our group within the scope of our trace gas emission monitoring program.
