description |
This dataset of radio-echo sounding internal reflecting horizons (IRH) which were traced across the radar surveys conducted in the 2019/20 Antarctic summer season at Little Come C, in the Dome C region of the East Antarctic Plateau. The data set is associated to publication: Chung, A., et al. (in review). The data were collected during a radar survey conducted in the Antarctic field seasons of 2019-20 using the Little Dome C - Very High Frequency (LDC-VHF) multichannel coherent radar depth sounder developed through a collaboration of The University of Alabama (UA), the University of Copenhagen (CPH) and the Alfred Wegener Institute (AWI). The survey covered Patches A and B of Little Dome C (Lilien et al., 2021), in order to select the exact drill site for the Beyond EPICA Oldest Ice drilling project. The datasets consists of 12 transects systematically covering Patches A and B with parallel lines, over an area of approximately 5×8 km^2. The 19 upper IRHs were linked from LDC to the EDC ice core site using the direct radar transect (profile number 20201012). Ages for IRHs were then calculated by linearly interpolating the EDC age-depth timescale from AICC2012 (Bazin et al., 2013) where the IRHs pass closest to the ice core site. IRH ages (in ka BP - before 1950) and uncertainties are provided in a text file, tab separated format file. |
