Petermann P1: Three-dimensional stratigraphic Horizon in the Petermann Glacier region, Greenland ice sheet (12.0 ka) ...
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...

Summary: | 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. ... : The 3D horizon and traced radar lines are provided in four different data formats:1. ASCII format of the point cloud of the 3D horizons (meshes.dat) or traced radar lines (line.dat) in the xyz format, where x and y represent the coordinates and z the elevation in meters.2. Digital Elevation Models (DEMs) in the GeoTIFF (.tif) and NetCDF (.nc) format of the 3D horizons (meshes). The DEMs have a cell size of 50 m.3. GoCAD (Geological Objects: The 3D horizons (meshes) are stored in triangulated surfaces (.ts) and the traced radar lines as polylines (.pl). ... |
