Sources of dissolved methane (CH 4 ) at Toolik Lake, Alaska, include both diffusion from lake sediments and groundwater entering the lake from its perimeter. Here we use hydrogen and oxygen isotopes in water (H 2 O), carbon and hydrogen isotopes in CH 4 , and carbon isotopes in dissolved inorganic c...
