Abstract:
Radio-echo sounding (RES) data from Jutulstraumen Glacier in western Dronning Maud Land (East Antarctica) recorded with the Alfred Wegener Institutes multi-channel ultra-wideband (AWI UWB) radar system in the Austral summer season 2018/19. The survey region is centered on the initiation zone of accelerating ice flow (~ 5 to 50 meters per year) at the onset of the Jutulstraumen Ice Stream, located within the Jutulstraumen drainage basin in western Dronning Maud Land, East Antarctica. This region marks the a transition from the thick ice sheet of the central plateau to the dynamic convergent ice flow regime leading through the Jutulstraumen Graben, which ultimately feeds into the Fimbul Ice Shelf. The RES profiles are organized into two distinct sets, each aligned approximately perpendicular to ice flow and spaced at intervals of 7.5 km. The data was mainly recorded in a frequency range between 180-210 MHz and is SAR processed. For further details see Franke et al., 2021 (https://doi.org/10.1002/esp.5203).
