Short summary
We present a high-resolution, quantitative reconstruction of dust provenance in the EPICA Dome C ice core (33.7–2.8 kyr BP) using Rare Earth Elements (REE). Dust was mainly sourced from Patagonia during glacial periods, shifting toward Australia, Southern Africa, and the Puna-Altiplano after 14.5 kyr BP due to sea-level rise and hydrological rearrangement in Patagonia. These changes also reflect major reorganizations of Southern Hemisphere atmospheric circulation.
