Raw multi-channel boomer seismic dataset from delta sites in Fiordland, NZ

General Information Raw multi-channel boomer seismic reflection data acquired during cruise 25PL1111 aboard RV Polaris II. The dataset comprises seismic profiles collected across delta sites in Bradshaw Sound, Doubtful Sound, and Dusky Sound, Fiordland, Aotearoa New Zealand.The dataset provides the raw seismic acquisition data together with associated navigation and acquisition geometry information. The data were collected to investigate the morphology and internal architecture of delta systems, including both modern and submerged delta deposits. Acquisition Parameters Source System: Applied Acoustics Boomer (AA301)Streamer: 24-channel Geometrics MicroEel streamer, 75 m lengthHydrophone spacing: 3.125 mBoomer frequency: 0.5–6 kHzSample interval: 125 μsPositioning: GNSS GPS mounted on the boomer source Navigation Navigation data are provided as separate files and source coordinates are also stored in the SEGY headers.
