This record describes sub bottom profiler data collected on RV Investigator voyage IN2021_T01, Brisbane to Darwin Transit which departed Brisbane (QLD) on the 11 Jun and returned to Darwin (NT) on the 22 Jun 2021. 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 except for certain operations. Data are stored in .raw (8,040 files 4.10 GB) raw and .seg (8,191 files 4.02 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
