We used a 1D numerical model constrained by radar horizons to find the age-depth profile at the the Australian Million Year Ice Core project drill site (MYIC; 75.34132 °S, 122.52059 °E) on Little Dome C (LDC), Antarctica. Further details on the model can be found in the associated publication: Chung et al., 2023 (The Cryosphere). The model was constrained by 19 horizons from the radar survey conducted during the 2019-20 Antarctic field season in a collaboration between the University of Alabama (UA), the University of Copenhagen (CPH) and the Alfred Wegener Institute (AWI), using the Little Dome C-Very High Frequency radar system (LDC-VHF; Chung et al., 2023, PANGAEA).. The age-depth profile extends to the deepest point where modelled age density < 20 ka/m - the threshold for which a paleoclimatic signal can reasonably be extracted.
