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/sporadically] for the extent of the voyage. Data are stored in *.raw (972 files 16.8 GB) raw and *.seg (7024 files 5.35 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 profiler data collected on RV Investigator voyage IN2021_V01, titled: "Quantifying krill abundance for krill monitoring and management off the Australian Antarctic Territory," which departed Hobart on the 29th January 2021 and returned to Hobart on the 24th March 2021 (AEST).

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/sporadically] for the extent of the voyage.

Data are stored in *.raw (972 files 16.8 GB) raw and *.seg (7024 files 5.35 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.
