The authors report a new ground based ice penetrating radar study of a potential ice core site. The new observations resolve internal reflecting horizons at a greater depth than previously observed. Tracing these horizons from the dated EDC core extends dated horizons as old as ∼600 ka into the study region. These observations give important new constraints on depth age modeling for ice older than the dated horizons. The authors use a modified Dansgaard-Johnson model to determine that
