Coastal wetlands are at the interface between terrestrial freshwater and marine and exhibit very specific biogeochemicalconditions. Intermittent sea water intrusion affects metabolic pathways, i. e. anaerobic carbon metabolismis progressively dominated by sulfate reduction with lower contribution of methanogenesis whilst methane productionis increasingly shifted from acetoclastic to hydrogenotrophic. Due to expanding anthropogenic impact a largeproportion of coastal ecosystems is degraded with severe implications for the biogeochemical processes.
