Abstract:

The FINEGIS F2 data set is located in Northern Greenland upstream of the northern branch of the 79° North close to the ice divide. On average the 3D horizon spans an area of 105 x 65 km and has an age of 52.2 ± 2.7 ka (thousand years). The data resemble two cylindrical fold units, which are located in the lower third of the ice column.

Comment:

The 3D horizon and traced radar lines are provided in three different data formats (because this data set contains overturning folds, we do not provide Digital Elevation Models):

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. GoCAD (Geological Objects: The 3D horizons (meshes) are stored in triangulated surfaces (.ts) and the traced radar lines as polylines (.pl).
