From: Global regulation of methane emission from natural lakes
Boxplot of methane emission estimates presented according to estimation method and emission pathway. (a) Contribution of each flux separately and all possible combinations to open water CH4 emission when all three types of flux were measured (n = 24). Diff. Flux = diffusive flux, Stor. = storage, Ebul. = ebullition. Bars combining the three fluxes represent the real total flux of an ecosystem. (b) Differences between CH4 fluxes (diffusive and ebullitive) measured using different methods. DC = dissolved concentration; SF = submersed funnel and FC = floating chamber. Different letters above the boxes mean there is a significant difference.
