RV Investigator Voyage IN2017_C01 SBP120 Sub-bottom Profiler Data

This record describes sub bottom profiler data collected on RV Investigator voyage IN2017_C01, 'GAB deep water geological and benthic ecology program' which departed Hobart on the 11 April 2017 and returned to Hobart on the 28 April 2017.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 258 files 5.58 GB raw and *.seg 258 files 5.41 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.
