The primary objective for this voyage were testing Seismic Systems. The voyage departed Hobart PW04 on the 15/12/2021 and returned to Hobart PW04 on the 20/12/2021. 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. Data are stored in *.raw (301 files 5.07 GB) raw and *.seg (146 files 2.53 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.

Brief description

This record describes sub bottom data collected on the RV Investigator voyage IN2021_E04, to calibrate and commission new, upgraded and existing critical equipment (with sea trials and personnel training) onboard RV Investigator for upcoming voyages in the 2021 schedule and beyond. The primary objective for this voyage were testing Seismic Systems. The voyage departed Hobart PW04 on the 15/12/2021 and returned to Hobart PW04 on the 20/12/2021.

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.

Data are stored in *.raw (301 files 5.07 GB) raw and *.seg (146 files 2.53 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.
