This record describes sub bottom profiler data collected on RV Investigator voyage IN2019_T03, "ORCA: Using the Investigator radar as a moving reference for the Australian operational radar network" which departed Darwin on the 23 December 2019 and returned to Henderson on the 2 January 2020. 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 (538 files 10.3 GB) raw and .seg (534 files 10.2 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 (for linear chirp) or bandpass filter (for ricker pulse), 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
