The biological consumption of methane has been studied in Framvaren, a Norwegian fjord 177 m deep with a well defined and stable sulfide interface at 18 m. The methane profile from the water column suggested that methane might be consumed at two depths, an aerobic zone between 12 and 16 m, and an anaerobic zone between 150 and 177 m. Water samples were incubated in bottles and poisoned with either Formalin or acetylene at four different times. Methane disappearance was detectable only in the 16‐, 150‐, 160‐, 170‐, and 177‐m samples. This disappearance was inhibited by both Formalin and acetylene in the 16‐m sample, but only by Formalin in the 150‐and 177‐m samples. These results suggest that both aerobic and anaerobic consumption of methane occur in this environment.
