Abstract

In 1990, methane release rates were similar between impoundments and averaged 705 and 600 pmol cm-2 min-1 (ie 162 and 138 mg CH4 m-2d-1). Water-column concentrations of dissolved CH4 were lower in one impoundment (33μM) than in the other 158μM). Rates of CH4 production by underlying peats were similar between impoundments and averaged 34.7 and 25.1 pmol cm-3min-1. In both impoundments, CH4 oxidation in the water and at the sediment-water interface seemed to be an important factor controlling its release. Moss-dominated wetlands adjacent to the impoundments had at least tenfold lower release rates for CH4 and fivefold lower concentrations of dissolved CH4. Beaver impoundments in woodland streams appear to be important local sources of atmospheric CH4. -from Authors
