    dct:description """This record describes sub bottom profiler data collected on RV Investigator voyage IN2017_E04, Trials voyage, which departed Hobart on the 7th of December 2017 and returned to Hobart on the 11th of December 2017.
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 sporadically for the extent of the voyage.
Data are stored in .raw (17 files 1.83 GB) raw and .seg (17 files 1.88 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.
Additional information regarding this dataset is contained in the GSM data acquisition and processing report. Additional data products may be available on request""" ;
