Greenhouse gas measurements were conducted along a moisture transect in the Gussola oxbow lake as part of the REWET project. The results reveal distinct emission patterns based on soil moisture levels. Unsaturated soil acts as a significant source of CO₂. Saturated soil predominantly emits methane. Interestingly, the site with intermediate moisture characteristics exhibited the lowest emissions across all three key greenhouse gases. CO₂, CH₄, and N₂O levels were the lowest there. This suggests a potential mitigation zone within the moisture spectrum. These findings underscore the importance of soil moisture in regulating greenhouse gas emissions in wetland ecosystems.
