This record describes sub bottom profiler data collected on RV Investigator sea trial voyage IN2015_E04, which departed Hobart 2015-04-25 and returned on 2015-04-28.
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 for a few hours while testing for acoustic interference (01:30 2016-04-26 - 11:15 2016-04-26)
Data are stored in *.raw (8 files 454 MB) raw and *.seg (8 files 448 MB) 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. Additional data products may be available on request
