PANGAEA, https://doi.org/10.1594/PANGAEA.990049 Abstract: In the Antarctic austral summer season of 2023/24 AWI ultra-wideband (UWB) data was acquired across prominent ice-streams draining parts of the DML region as part of the CHARISO (Swiss (CH) Antarctic Research Initiative - ISOchrones in East Antarctic outflow regions) project, providing an opportunity to trace isochrones there and compare their pattern with modelled isochrones from ice-sheet modelling. The data were further used to extend the layering across existing AWI DML lines in the upper section near the ice divide, and over the main ice divide to link up specific isochrones with the EDML and Dome Fuji ice cores and were recorded in a frequency range between 180-210 MHz. The data are available for both data products (qlook: unfocused; standard: SAR focused) as netCDF files (including waveforms and metadata), KML files of the profile line locations, and quicklook images of the radargrams.
