RV Investigator Voyage IN2022_T01 SBP120 Sub-bottom Profiler Data

This record describes sub bottom profiler data collected on RV Investigator voyage IN2022_T01, titled "Transit: Cairns to Darwin 2022." The voyage took place between September 11, 2022 and September 17, 2022 (AEST), departing from Cairns and returning to Darwin.The Kongsberg SBP120 (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 SBP120 was logged continuously for the extent of the voyage.Data are stored in *.raw (702 files 16.6 GB) raw and *.seg (695 files 16.4 GB) segy formats at CSIRO.The segy format data had a real time processing stream applied, which applies gain, a gain correction, and matched filter with replica shaping.Additional information regarding this dataset is contained in the GSM data acquisition and processing report.
