Radon isotopes as tracers of climate-sensitive subsurface connectivity in Antarctic permafrost
Rn anomalies were more widespread in 2019/20 compared with the colder 2023 campaign, suggesting that short-term meteorological conditions can modulate subsurface connectivity and gas transport efficiency. These results show that radon isotopes provide a practical framework for identifying shallow versus deeper gas pathways and for monitoring climate-sensitive changes in Antarctic permafrost systems.
