Carmel E. Johnston, Stephanie A. Ewing, Jennifer W. Harden, Ruth K. Varner, Kimberly P. Wickland, Joshua C. Koch, Christopher C. Fuller, Kristen L. Manies, M. Torre Jorgenson
2014, Environmental Research Letters (8) 1-12
Permafrost soils store over half of global soil carbon (C), and northern frozen peatlands store about 10% of global permafrost C. With thaw, inundation of high latitude lowland peatlands typically increases the surface-atmosphere flux of methane (CH4), a potent greenhouse gas. To examine the effects of lowland permafrost thaw over...
