Coastal systems, which represent the terrestrial-aquatic continuum, are unique ecosystems with highly dynamic hydro-biogeochemical transformations. These systems occupy relatively small areas of the Earth’s surface, but play an important role in global biogeochemical cycles. The structure and function of terrestrial-aquatic interfaces (TAIs) is extremely sensitive to changing environmental and climatic conditions, but these are not adequately represented in our mechanistic models. There are still many mechanisms and processes in these dynamic systems that are poorly understood, including interactions between climate, soil chemistry, hydrology, microbial communities, and plant communities. A concerted multidisciplinary approach is needed to better understand these systems through a combination of experimentation, monitoring, and models. This session aims to facilitate a discussion of processes occurring in TAIs across various spatial and temporal scales, using field, laboratory, and modeling case studies. Specific importance is placed on model-experiment integration (ModEx). We encourage abstract submissions on a variety of related and interdisciplinary topics related to hydrological, chemical, and biochemical processes occurring during sea level rise and storm surges, variable inundation events, and prolonged saturation of soil systems.
