The data were acquired using 1 to 3 GI-Guns (Sercel) and a 600 m-long streamer in East Antarctica. Details of the data acquisition parameters are provided in the expedition report (Krastel, 2025). These data are processed (Bandpass-filtering, FK-filtering, CDP sorting and velocity analysis, normal moveout corrections and migration), seismic reflection profiles. The Profile AWI2024-0009 is shorten to grounding-zone wedge.
