	<a title='This record describes sub bottom profiler data collected on RV Investigator voyage IN2024_V04, Linking East Australian Current dynamics and submarine canyon geomorphology to marine ecosystem hotspots which departed Sydney on the Friday 7th and returned to Brisbane on the on the Wednesday 3rd July. 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 echosounders frequency sweep range is from 2.5 to 7 kHz. The SBP120 was logged sporadically for the extent of the voyage, it was run during video tow line mapping and when mapping lines of interest for the science party. Data are stored in *.raw (402 files 6.64 GB) raw and *.seg (401 files 6.57 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.

The Simrad EK60 split beam echosounders for 18kHz and Simrad EK80 split beam echosounders for 38, 70 120, 200 and 333 kHz were used to acquire acoustic backscatter data to a range of 1500 m, between Sydney and Brisbane, with primary mapping focused on Richmond and Solitary Canyons. If the bottom was deeper than 1500 m during the camera operations the logging range was extended to capture the full water column. All frequencies were logged sporadically for the extent of the voyage as to not interfere with the ADCP which took priority over the EK60/EK80 to fulfil the voyage objectives.

The voyage departed Fremantle on the 09 March and returned to Hobart on the 20 March.

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.
