E23A:
Observing and Modeling Wetland-Estuarine Exchanges and Interactions: State of Knowledge, Challenges, and Future Directions I


Session ID#: 36820

Session Description:
Tidal wetlands and estuaries are tightly interlinked ecosystems at the terrestrial-aquatic interface, and should be studied as such to gain insights into how future changes will affect coastal biogeochemical cycles, metabolism, and ecosystem functioning. Yet, despite recent advances in observations and modeling of biogeochemical and physical processes in terrestrial and ocean environments, a large gap still exists in our ability to link these systems and quantify exchanges and interactions at wetland-estuarine margins. Multidisciplinary data, high-resolution remote sensing observations of both the terrestrial and aquatic landscapes, and coupled hydrodynamic-biogeochemical mechanistic models are needed to constrain nutrient and carbon fluxes at this interface and quantify wetland contributions to coastal and global biogeochemical cycles. This session will bring together modelers, observationalists, and stakeholders to exchange information and understanding on the current ‘state-of-knowledge’, gaps, challenges, and future directions in observing and modeling wetland-estuarine exchanges and interactions in low, mid, and high latitude environments. Specific topics may include synthesis activities across coastal systems; new methods for estimating nutrient dynamics, carbon stocks, and fluxes using in-situ and remote sensing observations from different platforms; and development of high-resolution, 3D mechanistic models with appropriate parameterizations for the key physical, chemical, and biological processes that shape wetland-estuarine ecosystems.
