Abstract:
We present five internal reflection horizons (IRHs) derived from airborne radar data in western Dronning Maud Land on the East Antarctic Plateau. The data were collected during the 2023/24 season using the AWI ultra-wideband radar system in wideband mode (150–520 MHz). Information from firn core B52 are used for dating the IRHs, which span the period from 1209 to 2024. Surface mass balance is derived from each IRH for the mass per time between two consecutive IRHs.
