Abstract:
The airborne campaign 'RIISERBATHY' saw the acquisition of geophysical data across the Riiser-Larsen Ice Shelf in East Antarctica during the austral summer of 2022/2023, with Neumayer-III and Troll as base stations. It was jointly funded by the Alfred Wegener-Institute, Helmholtz Centre for Polar and Marine Research, Bremerhaven, Germany, and the Federal institute of Geosciences and Natural Resources, Hannover, Germany. Grant number of the Alfred Wegener Institute for this campaign is 'AWI_PA_02138'. 'RIISERBATHY' is part of the overarching 'GEA' project (Geodynamic Evolution of East Antarctica). Here, airborne radio-echo sounding data are deposited, acquired using the Aero EMR system described by Nixdorf et al. (1999). Related ice base and surface picks are deposited within PANGAEA as well [link/doi]. Related GNSS master tracks, and potential field data are deposited within PANGAEA as well and can be found using the PANGAEA identifier for this campaign, 'P5-236_RIISERBATHY_22_23' (https://www.pangaea.de/?q=campaign:%22P5-236_RIISERBATHY_22_23%22).
The ice penetrating radar system used operates with a centre frequency of 150 MHz and has been widely utilized in Antarctica since the mid-90s (Steinhage, 2001). An extensive description of the system is done by Nixdorf et al. (1999). During 'RIISERBATHY' it was flown in toggle mode, alternately acquiring data with both a short and a long pulse of 60 and 600 ns. This mode reduces horizontal resolution to 9.4 m at 70 m/s from 4.7 m, compared to operating in single-pulse mode, but allows to map internal layers with its short pulse and ice thicknesses of up to 4000 m with its long pulse (Steinhage, 2001).
