Description:
We used a 1D numerical model constrained by radar horizons to find the age-depth profile at the European Beyond EPICA - Oldest Ice project drill site (BELDC; 75.29917 °S, 122.44516 °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.
