Three-dimensional anatomy of folded radar stratigraphy in polar ice sheets ...

Here, we present a collection of data sets of reconstructed three-dimensional (3D) englacial stratigraphic horizons in the polar ice sheets. The 3D horizons were created on the basis of internal reflection horizons (IRHs), which were made visible by radio-echo sounding (RES) data. We explain how 3D...

Description
Summary:Here, we present a collection of data sets of reconstructed three-dimensional (3D) englacial stratigraphic horizons in the polar ice sheets. The 3D horizons were created on the basis of internal reflection horizons (IRHs), which were made visible by radio-echo sounding (RES) data. We explain how 3D horizons provide an improved data basis for the interpretation of deformed radar stratigraphy, which is needed to better understand the ice-flow history of the Greenland and Antarctic ice sheet. The data cover different survey regions, which represent crucial ice-dynamic settings. We provide the data in different formats to enable a wide range of applications and reproduction of the results: (1) point clouds of the 3d horizon meshes containing the x, y and z coordinates in the ASCII format, (2) a gridded digital elevation model based on the point cloud data in the GeoTIFF format and (3) GoCAD geological objects of the 3d horizons. The 3D horizons are provided in three different data formats: GoCAD objects, point ...
