RV Investigator Voyage IN2021_E01 SBP120 Sub-bottom Profiler Data
This record describes sub bottom profiler data collected on RV Investigator voyage IN2021_E01 (Trials and Calibration), which departed Hobart on the 10th November 2021 and returned to Hobart on the 14th November 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/sporadically] for the extent of the voyage.
Data are stored in *.raw (596 files, 1.81GB) raw and *.seg (595 files, 1.8 GB) segy formats at CSIRO.
The segy format data had a real time processing stream applied, which applies gain, a gain correction, bandpass filter (for depths < ~200m) or matched filter with replica shaping (for depths > ~200 m), and time variable gain. No attribute calculation for instantaneous amplitude was applied.
