Folded ice stratigraphy in North East Greenland: A three dimensional structural analysis
Advances in radio-echo sounding technology over the last two decades made it possible to map complex englacial structures in the lower part of the Greenland and Antarctic Ice Sheet. Deformation structures are made visible by distorted isochrones acting as radar reflectors. Decoding the formation his...

Advances in radio-echo sounding technology over the last two decades made it possible to map complex englacial structures in the lower part of the Greenland and Antarctic Ice Sheet. Deformation structures are made visible by distorted isochrones acting as radar reflectors. Decoding the formation history of these structures offers an excellent possibility to reconstruct past ice movements, and thus provides an additional archive about processes on the earth's surface in the past. In this study, we use ultra-wideband ice-penetrating radar data to map the deformation of the radar stratigraphy in Northern Greenland. We construct 3-dimensional horizons from folded radar layers of features which show no apparent link to the current velocity field or the regional bed topography. Furthermore, we are able to constrain the geometry and spatial extend of folds, which suggests that they were formed in several stages and in a different ice-dynamic setting than the present one in Northern Greenland. |
