Abstract:
We present a high-resolution airborne radar data set (CHIRP 2019) for the Princess Ragnhild Coast, Dronning Maud Land, East Antarctica. The radar data has been acquired in December 2018 and January 2019 with the Alfred Wegener Institute (AWI) multichannel ultra-wideband radar mounted on the Polar6 aircraft. Radar profiles cover the Princess Ragnhild Coast in Dronning Maud Land, East Antarctica (20° E - 28° E). They cover the western Roi Baudouin Ice Shelf, the Jotneisen Ice Shelf, and the eastern Munisen Ice Shelf as well as the three ice rises Hamarryggen, Lokeryggen and Derwael. Even though the Princess Ragnhild coast has been close to balance in recent decades and is likely dynamically stable , the individual catchments are sensitive to increased ocean melting because some tributary glaciers rest on a retrograde, landward sloping bed . Together, the catchments drain a land ice mass with a eustatic sea-level equivalent of 2 m. We provide radar data in two processing levels: (1) unfocussed SAR (qlook), and (2) foscussed SAR (standard).
