Hydrological and biogeochemical connectivity across coastal watersheds and estuaries: linking terrestrial and aquatic processes
Session ID#: 81991
Session Description:
Water plays a central role on the transport and transformation of geochemical constituents across the continuum of soils, sediments, rivers, oceans, and atmosphere. Understanding of the interconnection between hydrological and biogeochemical cycles is rapidly advancing in inland systems, however, these interconnections become more complex along the coast, where tides, sea level rise, and storm surge drive two-way exchange of water with the terrestrial landscape that likely influences the biogeochemical function of terrestrial and aquatic ecosystems. In this session, we seek to improve our comprehension and ability to model the fundamental mechanisms driving biogeochemical fluxes and transformations across terrestrial and aquatic ecosystems near the coast, including both small coastal watersheds, the tidally-influenced reaches of larger watersheds, and nearshore estuarine environments. We invite contributions from all areas of biogeochemistry, molecular biology, and predictive modeling that cut across ecosystem boundaries, linking at least two terrestrial-aquatic subsystems (e.g., i.e., non-tidal, tidal, and estuarine).
