Modelled age-depth profile at location of the Million Year Ice Core project drill site (MYIC) based on the sledge-borne DEep LOoking Radio Echo Sounder (DELORES) survey
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...
