![Urban land uses strongly influence microbial carbon cycling along the terrestrial-aquatic systems. This work identifies specific locations (i.e., control points) exerting strong impact on carbon biogeochemistry and to understand the interplay of molecular controls, nutrient supply, and hydrologic factors that fuel the rapid microbial carbon processing at these locations, impacting downstream coastal systems. A molecular-scale understanding is critical to accurately predicting highly dynamic urban and coastal carbon cycles.
