Methane flux pathways can vary in strength across space and time. In this study, we measured methane emissions from a Cypress-Tupelo swamp in south Louisiana. We scaled these measurements to estimate total flux at the plot level. During the summer, methane release from bubbling (ebullition) was the dominant pathway. In winter, bubbling decreased sharply, where plant-based flux and diffusion from the water surface became more prominent. These seasonal shifts show how methane emissions change over time and underscore the need to represent such variability in models of carbon cycling in wetland ecosystems.
