Swamps cover much more of the landscape than previously thought yet are largely absent from literature. This lack of data has led to swamps being excluded from most mapping, carbon accounting, and climate modelling, possibly vastly underestimating the amount of carbon stored, the impacts on greenhouse gas production and uptake, and their role in catchment hydrology. Much of the areal extent of swamps is in higher latitudes, a region under disproportionate stress from climate change, though those located in temperate, sub-, and tropical regions are not immune. This session welcomes contributions on a variety of research focused on natural and disturbed swamp ecosystem processes in hydrology and biogeosciences. Presentations on biogeochemical processes, measuring or modeling carbon (or other nutrient) stocks and cycling, ecohydrology, disturbance and restoration, aquatic or terrestrial processes, at site to landscape scales will all be considered.
