This record describes sub bottom profiler data collected on RV Investigator voyage IN2020_V09 (SOTS: Southern Ocean Time Series automated moorings for climate and carbon cycle studies southwest of Tasmania), which departed Hobart on the 27th August 2020 and returned to Hobart on the 12th September 2020. In addition to the tasks at the SOTS site the voyage also recovered a Rintoul mooring that was deployed during IN2020_V05. 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 sporadically for the extent of the voyage (i.e. during transits). Data are stored in .raw (572 files 5.95 GB) raw and .seg (572 files 5.95 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, and time variable gain. No attribute calculation for instantaneous amplitude was applied. Additional information regarding this dataset is contained in the GSM data acquisition and processing report.
