Full description

This record describes sub bottom profiler data collected on RV Investigator voyage IN2025_V06, The Coral Sea Frontier which departed Brisbane on Friday 10 October 2025 and returned to Brisbane on Friday 14 November 2025.

The Kongsberg SBP29 (sub bottom profiler) was used to acquire data containing the specular reflections at different sediment interfaces below the seafloor. The SBP120 provides a 3° by 3° angular resolution.

The echosounder's frequency sweep range is from 2.5 to 7 kHz. The SBP29 was logged for the extent of the voyage.

Data are stored in *.raw (1,036 files 23.2 GB) raw and *.seg (517 files 11.5 GB) segy formats at CSIRO.

The segy format data had a real time processing stream applied, which applies gain, a gain correction, matched filter with replica shaping, an attribute calculation for instantaneous amplitude and time variable gain.

Additional information regarding this dataset is contained in the GSM data acquisition and processing report. Additional data products may be available on request
