Critical Zone (CZ) research in the geosciences focuses on understanding the complex, interdependent processes that occur from the top of the vegetation canopy to the bottom of the aquifer. This session focuses on the critical interfaces within the CZ where biological, chemical and physical processes converge and interact. These interfaces, including the soil-vegetation-atmosphere interface, the weathered bedrock-soil interface and the water table, are crucial in regulating nutrient cycling, water filtration and ecosystem dynamics. By studying these zones of interaction, researchers aim to elucidate how natural and anthropogenic changes affect ecosystem services. This session would like to reflect the diversity of observational methods and modelling approaches that are being developed by researchers. In particular, we will appreciate studies on the use on (geo)physical methods that have the potential to unveil the invisible properties and processes within the CZ in a non-invasive manner and that have now reach unprecedented high spatial and temporal resolution. The session is also meant to focus on the interplay between these physical or chemical measurements and improved model conceptualization and parametrization at all spatial and temporal scales.
