Full description

This record describes sub bottom profiler data collected on RV Investigator voyage IN2021_E02, to calibrate and commission new, upgraded and existing critical equipment (with sea trials and personnel training) onboard RV Investigator for upcoming voyages in the 2021 schedule and beyond. The primary objectives for this voyage were testing the Deep Corer winch stream and respool, Trawling winch calibration, CTD winch 1 & 2 calibrations, HOTS commissioning and Heave Compensation testing, and Deep Towed Camera trial and calibration. The voyage took place between November 20 and November 28, 2021, departing from Hobart (TAS) and returning to Hobart.

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 (565 files 4.17 GB) raw and *.seg (567 files 4.16 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
