Modelled age-depth profile at location of the Beyond EPICA drill site (BELDC) based on the Little Dome C-Very High Frequency radar system (LDC-VHF) survey
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...
