    NC Greenland NG1: Three-dimensional stratigraphic Horizon in the Northern Central Greenland ice sheet (13.8 ka) (2023)
    PANGAEA
    Details
    Publication Date: 2024-04-20
    Description: The NG1 3D horizon is located in northern central Greenland and covers an area of approximately 690 x 55 km and reaches almost from the eastern to the western outlet systems. The age of NG1 is 13.8 ± 1.0 ka (thousand years). NG1 extends in the east into the NEGIS trunk and shows in this area similar short-wavelength folds, which are observed in the NEGIS shear margins. Furthermore, NG1 resembles several cylindrical upright folds in the eastern and western edges of the horizons. The fold axes of the cylindrical folds in the west trend approximately west, whereas the trend of the cylindrical folds in the east trend north. In the central-eastern area, we find a large bump in the bed topography due to the paleofluvial mega-canyon, which is imprinted in the 3D horizons mimicking this bed depression. In the central-west, we find cylindrical upright folds trending in two different directions (north and north-west).

    NC Greenland NG2: Three-dimensional stratigraphic Horizon in the Northern Central Greenland ice sheet (37.5 ka) (2023)
    PANGAEA
    Details
    Publication Date: 2024-04-20
    Description: The NG2 3D horizon is located in northern central Greenland and covers an area of approximately 690 x 55 km and reaches almost from the eastern to the western outlet systems. The age of NG2 is 37.5 ± 2.1 ka (thousand years). NG2 extends in the east into the NEGIS trunk and shows in this area similar short-wavelength folds, which are observed in the NEGIS shear margins. Furthermore, NG2 resembles several cylindrical upright folds in the eastern and western edges of the horizons. The fold axes of the cylindrical folds in the west trend approximately west, whereas the trend of the cylindrical folds in the east trend north.

    Basal unit at Little Dome C, Antarctica (2023)
    PANGAEA
    Details
    Publication Date: 2024-06-12
    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.
