The Radioisotope Geochemistry Lab (RGL) at the University of Southern Mississippi (USM) focuses on applying a diverse suite of geochemical tracers, particularly elemental radioisotopes, to investigate a wide range of marine and environmental processes. Our research is primarily centered on particle scavenging, carbon dynamics, and export fluxes in both coastal and open-ocean environments, with a strong emphasis on environmental and climate change impacts.

A significant aspect of our work involves exploring the efficiency and strength of the Biological Carbon Pump (BCP) under changing oceanic conditions. We aim to understand the key biogeochemical and physical factors influencing both BCP, coastal carbon cycling and Marine Carbon Dioxide Removal (mCDR) & Sequestration, which are critical components of the global carbon cycle and ocean-based climate mitigation strategies.
