B078:
Unraveling Hydro-Biogeochemical Dynamics across Tidally-Influenced Terrestrial-Aquatic Interfaces





Session ID#: 27274

Session Description:
Tidally-influenced near-shore systems represent a direct interface between terrestrial and aquatic ecosystems. These terrestrial-aquatic interfaces contribute significantly to biogeochemical cycling along the land-water-atmosphere continuum and provide functions critical to human society and ecosystem health. Processes occurring within terrestrial-aquatic interfaces are sensitive to chronic and rapid environmental perturbations. However, current models are not able to predict the outcome of perturbations because we lack (1) mechanistic understanding of hydro-biogeochemical processes and (2) appropriate data to inform predictive models in dynamic, tidally-influenced freshwater and marine systems. In this session we seek studies using novel observational and advanced modeling approaches—and especially encourage data-model integration—that help resolve knowledge gaps at all relevant scales, from pore to global, within tidally-influenced terrestrial-aquatic interfaces. This session will deepen our understanding of perturbation impacts and key feedbacks within coupled hydro-biogeochemical systems along the terrestrial-aquatic continuum that will ultimately reduce uncertainties in ecosystem model predictions.
