    Locations, outlines and ICESat-2 tracks of active lakes at the onset of the Jutulstraumen Glacier (Antarctica) (2021)
    PANGAEA
    Details
    Publication Date: 2024-05-17
    Description: We analysed a 6 year time series of displacement maps from Sentinel-1 SAR interferometry in the upstream region of Dronning Maud Lands Jutulstraumen Glacier (Antarctica). Our results reveal short-term cascade-like events of subsidence and uplift of the ice surface, which we interpret as drainage and filling of subglacial water pockets. This indicates a periodic transport of subglacial water through an interconnected drainage system. The water re-location events in this study are located in a slow flowing region 225~km upstream of the grounding line. An examination of high-resolution ultra-wideband radar data and the hydropotential gradient reveals that subglacial water is moving downstream along a canyon-like system of local valleys.

    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).

    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.
