Ice Thickness from Jutulstraumen Glacier recorded with the airborne AWI UWB radar system, Antarctica ...
Focus of this project was to map the disturbances of the radar stratigraphy at the shear margins of the Jutulstraumen, a large outlet glacier in Dronning Maud Land (DML), Antarctica, as well as within its main trunk. This project will help to improve our understanding of the formation processes of s...
