RV Investigator Voyage IN2019_T01 SBP120 Sub-bottom Profiler Data

Brief description

This record describes sub bottom profiler data collected on RV Investigator voyage IN2019_T01, CAPSTAN which departed Hobart on the 29th April 2019 and returned to Fremantle on the 11th May 2019.
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 except for period mapping the shipping sealane from Albany to near Fremantle.
Data are stored in .raw (130 files 5.35 GB) raw and .seg (130 files 5GB) 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
