Methane ebullition flux data from thermokarst lakes, 2003-2010
We collected ebullition data from thermokarst lakes near the Northeast Science Station in Cherskii, Russia (68.75°N, 161.39°E ) and Fairbanks, Alaska (64.92°N, 147.85°W) during the years 2003-2010. Ebullition data were collected using submerged bubble traps placed over discrete ebullition seeps. Ebu...
