This record describes sub bottom profiler data collected on RV Investigator voyage IN2016_v05, "The Great Barrier Reef as a significant source of climatically relevant aerosol particles." The voyage departed Brisbane on 28th September 2016. Leg 1 ended on 11 October with a personnel transfer at Fitzroy Island. Leg 2 ended on 16 October with another personnel transfer at Magnetic Island, then the voyage ended in Brisbane on 24 October 2016. 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 (71 files 14.4 GB) raw and .seg (71 files 14.3 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
