Full description

This record describes sub bottom profiler data collected on RV Investigator voyage IN2025_V02, ' SOTS: Southern Ocean Time Series automated moorings for climate and carbon cycle studies southwest of Tasmania ' which departed Hobart on the 26th March and returned to Hobart on the 14th April 2025.

The Kongsberg SBP29 (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 to 9 kHz. The SBP29 was logged continuously for the extent of the voyage.

Data are stored in *.raw (251 files 5.66 GB) raw and *.seg (250 files 5.63 GB) segy formats at CSIRO.

The segy format data had a real time processing stream applied, which applies gain, a gain correction, and matched filter with replica shaping (for water depths typically >200m) or Bandpass filtering 2-9 kHz (in water depths typically <200 m).

Additional information regarding this dataset is contained in the GSM data acquisition and processing report. Additional data products may be available on request
