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.

Isotope ratio mass spectrometry (IRMS) leverages magnetic sector mass spectrometry to enable high-precision measurement of the stable isotope content of a sample. Typical measurements target hydrogen, carbon, nitrogen, and oxygen analyses—although elements with masses up to and including sulfur can be measured.

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.
