Characterizing and Managing Hydrobiogeochemical Processes at Critical Interfaces in Critical Zones
Session ID#: 161374
Session Description:
Critical interfaces within the critical zone are environments where complex transformations and interconnected fluxes of carbon, nutrients, solutes, heat and water are concentrated. Controlling factors at these interfaces, such as lithologic characteristics, climate, vegetation, microbial processes, and management, can significantly impact the functioning of the Critical Zone (CZ) with implications for water quality, carbon sequestration, and land-atmosphere interactions, among others. Understanding processes at these interfaces (hotspots) and at relevant timescales (hot moments) is critical to predicting the effects of natural and human (e.g., land use) disturbances. This session invites contributions that focus on (1) new techniques for identifying CZ hotspots and hot moments at critical interfaces and their propagation across scales, (2) data analysis, experimental, sensing, and modeling techniques to gain process understanding and explore predictability, (3) incorporating spatiotemporal variability in models, and/or (4) quantifying the significance of incorporating emergent behaviors in models on our predictive understanding of CZ processes.
