EC14B:
Coastal Wetlands as an Important Interface Between Land, Sea, and Atmosphere: Capturing Temporal and Spatial Variability in Chemical Fluxes Posters


Session ID#: 9466

Session Description:
Coastal wetlands, including tidal marshes, mangroves, and seagrass beds, occur along much of the world’s shoreline, with an area of ~500,000 km2. These ecosystems continue to experience rapid loss due to coastal development, sea level rise, hydrological and sediment supply alterations, and other processes. In addition to their ecological roles, coastal wetlands are a major sink for carbon dioxide and contain important carbon stocks in soils and biomass. Under some circumstances they may be important sinks or sources for other greenhouse gases such as methane and nitrous oxide. Lateral fluxes via tidal exchange between wetlands and adjacent estuaries and oceans may also be important to wetland and connected water body chemical budgets. However the magnitude and processes controlling exchange between coastal wetlands, the atmosphere and ocean remain uncertain, due to the large spatial and temporal variability in these fluxes, and lack of a theoretical framework. This session will investigate exchange across the interface between coastal wetlands, the atmosphere and the adjacent ocean. We welcome submissions on chemical exchange, including greenhouse gases, carbon, alkalinity, and nutrients, across all spatial and temporal scales. Presentations that highlight novel instrumentation approaches, high resolution time series, spatio-temporal variability, isotopic sources, and modeling approaches are encouraged
