Methane ebullition flux data from thermokarst lakes, 2003-2010



This dataset contains ebullition flux measurements from thermokarst lakes in Siberia and Alaska. Data were collected using submerged bubble traps placed over discrete ebullition seeps. Ebullition values are reported volumetrically (mg CH4 per seep per day), the latter based on mean values of methane measured in ebullition seeps on the study lakes [A = 82±7 % CH4; B = 83±12 % CH4; C = 85±5 % CH4; HS = 89±3 % CH4]. Data were gathered from May 2003 through October 2010.
