NEGIS N1: Three-dimensional stratigraphic Horizon in the upstream region of the Northeast Greenland Ice Stream, Greenland ice sheet (7.3 ka)
The NEGIS N1 3D horizon is located at the onset of Greenlands Northeast Greenland Ice Stream and has an age of 7.3 ± 0.2 ka (thousand years). NEGIS N1 covers an area of ∼ 250 x 90 km and is centred at the EastGRIP drill site. The geometry of this 3D horizon shows a variety of complex and high number...

Summary: | The NEGIS N1 3D horizon is located at the onset of Greenlands Northeast Greenland Ice Stream and has an age of 7.3 ± 0.2 ka (thousand years). NEGIS N1 covers an area of ∼ 250 x 90 km and is centred at the EastGRIP drill site. The geometry of this 3D horizon shows a variety of complex and high number of folds, which are increasing in ice-flow direction. A number of short-wavelength folds (100-500 m long and with amplitudes up to 100 m high) extend almost from the ice divide downstream along the shear zone of NEGIS. |
