Full description
This record describes multibeam echosounder data collected on RV Investigator voyage IN2020_V10, titled MNF Trials, Storm Bay Modelling and Information System Data Collection, and Bathymetric and Benthic Habitat mapping of the Huon AMP. The voyage took place from 11-22 November 2021 departing from Hobart (TAS) and returning to Hobart (TAS).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 ( 1332 files 7.99GB) raw and *.seg (XX files XX 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
