| Zusammenfassung |
| We present a novel automated processing method for obtaining layer dip from radio-echo sounding (RES) data. The method is robust, easily applicable, and can be used to process large (several terabyte) ground and airborne RES datasets using modest computing resources. The automated RES processing (ARESP) method comprises several basic steps including: noise reduction; radar layer identification; measurement of orientation and other object properties; elimination of noise in the dip datasets data; and the collation of valid dip information. Pending test results and further development (Hiess et al. in prep), the large-scale dip datasets produced by the method should aid glaciologists seeking to understand ice flow dynamics in Greenland and Antarctica.
