B24A:
Beyond Ecosystem Boundaries: Integrating Terrestrial and Aquatic Processes to Advance Catchment Biogeoscience II


Submit an Abstract to this Session


Session ID#: 59673

Session Description:
In-stream nutrient dynamics, watershed biogeochemical budgets, or hydrologic mobilization of nutrients are often analyzed and interpreted independently from the spatial distribution of relevant processes such as terrestrial primary productivity, decomposition, or respiration. However, the propagation of energy, water, and biological processes are manifested as emerging patterns across the terrestrial-aquatic interface, and truly integrating these processes is a critical next step for catchment biogeoscience. We invite contributions of studies that cross traditional terrestrial and aquatic ecosystem boundaries by using state-of-the art measurement and modeling techniques to better quantify catchment-scale transport, transformation, and fate of water, carbon, and nutrients. Studies with a synthetic view of terrestrial-aquatic connections are particularly encouraged, as are field-based or modeling studies whose experimental design specifically targets these connections.
