Progress Code: completed Maintenance and Update Frequency: asNeeded Statement: Original field data. This record describes sub bottom profiler data collected on RV Investigator voyage IN2017_V01, 'Interactions of the Totten Glacier with the Southern Ocean through multiple cycles. ‘Sabrina Seafloor Survey' which departed Hobart on the 14th January 2017 and returned to Hobart on the 5th March 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 continuously for the extent of the voyage. Data are stored in *.raw (381 files 5.81 GB) raw and *.seg (220 files 3.62 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.
