    Bedrock at Little Dome C, Antarctica (2023)
    PANGAEA
    Details
    Publication Date: 2023-12-20
    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. (2023). 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 dataset contains 19 IRHs, the basal unit horizon and the ice-bed interface which were manually traced by Ailsa Chung, using the seismic environment of the Echos software from Paradigm Geophysical. A single file for each IRH is provided in a text file, tab separated format with both depth and two-way travel time. The conversion to depth done using c = 0.1685 m/μs and firn correction of 10 m. The IRHs are provided at approximately 3.5 m spacial resolution.

    Petermann P2: Three-dimensional stratigraphic Horizon in the Petermann Glacier region, Greenland ice sheet (37.5 ka) (2023)
    PANGAEA
    Details
    Publication Date: 2024-04-20
    Description: The Petermann P2 3D horizon is located at the onset of the Petermann Glacier and covers an area of approximately 156 x 95 km. Horizon P2 is ∼ 37.5 ± 2.1 ka old and represents approximately the transition from the last glacial period to the Holocene period. It is located on average 1 km below the ice surface. The horizon is mainly characterized by open cylindrical folds with the fold axis oriented parallel to ice flow. The amplitudes of the folds reach up to 1 km with a wavelength of 10-15 km and are highest in the centre of the data set. P2 (in contrast to P1) shows gaps in regions where the 3D horizons could not be created due to uncertainties or poor visibility of the IRHs. Therefore, the datasets provided for horizon P2 are subdivided into P2A and P2B.

    Petermann P1: Three-dimensional stratigraphic Horizon in the Petermann Glacier region, Greenland ice sheet (12.0 ka) (2023)
    PANGAEA
    Details
    Publication Date: 2024-04-20
    Description: The Petermann P1 3D horizon is located at the onset of the Petermann Glacier and covers an area of approximately 156 x 95 km. Horizon P1 is ∼ 12.0 ± 0.9 ka old and represents approximately the transition from the last glacial period to the Holocene period. It is located on average 1 km below the ice surface. The horizon is mainly characterized by open cylindrical folds with the fold axis oriented parallel to ice flow. The amplitudes of the folds reach up to 1 km with a wavelength of 10-15 km and are highest in the centre of the data set.
