Short summary
In this study, we model vertical atmospheric gas diffusion in ice older than 1 million years in the Antarctic ice sheet. We estimate climate signal preservation and help identify a potential region for a future deep ice core in East Antarctica. We find that regions with low accumulation rates and moderate ice thickness result in lower diffusion rates. In particular, the foothills of Dome A is a promising location for a deep ice core that extends the present ice core record.
