Abstract:
Seismic reflection profile collected during RV Polarstern cruise PS141 on the Vincennes Bay shelf in March 2024. Data was recorded with a 600 m long digital streamer and 2 GI-Guns (Sercel) as seismic source, details of data acquisition, can be found in report of Expedition PS141 (Krastel, 2025). This is a processed migrated seismic reflection profile for processing details consult header file or segy text headers.
