This Lawrence Livermore National Laboratory (LLNL) Science Focus Area (SFA) investigates biogeochemistry at interfaces from the nanometer scale in the laboratory to the meter scale in the field to identify the dominant biogeochemical processes and underlying mechanisms that control metal and radionuclide mobilization in surface water and groundwater.

Diagram showing the responses of a general ecosystem to the effects of increased atmospheric CO2. The effects start at the physiological scale on the left side and cascade through ecosystem processes of increasing scale from left to right. Solid arrows represent carbon flows and dashed arrows represent an influence of one process on another. Looped feedbacks through the plant and soil system can be seen.

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.
