While biogeochemical reactions govern carbon cycling, water quality, remediation efficacy, nutrient allocation for crops among other critical ecosystem processes, quantifying such processes over field-relevant scales is challenging. The challenge stems from the complexity of interactions between microbes, minerals, dissolved constituents, fluids, organic matter, and vegetation within and across compartments of our Earth system; how hydrology drives these interactions; and how the interactions respond to stress.
We are advancing a range of geophysical approaches to tools that characterize and monitor changes in hydrological-biogeochemical properties/processes using geophysical measurements. In conjunction with theory and models, we use the geophysical datasets to develop new insights about complex ecosystem behavior and its response to environmental stress or manipulation.
