RV Investigator Voyage IN2023_V06 SBP120 Sub-bottom Profiler Data

This record describes sub bottom profiler data collected on RV Investigator voyage IN2023_V06, titled: "Understanding Eddy Interactions and Their Impacts In the East Australian Current System." The voyage took place between October 9 and November 2, 2023, departing from Sydney (NSW) and returning to Sydney.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/sporadically] for the extent of the voyage.Data are stored in *.raw (492 files 9.12 GB) raw and *.seg (491 files 9.06 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.
