Full description

This record describes scientific split-beam echosounder data collected on the RV Investigator voyage IN2023_V02, titled "Gigantic submarine landslide offshore western Tasmania: risk mitigation for shelf derived tsunami in Australia", which departed Hobart on March 24 and returned to Hobart on April 30, 2023.

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 250 m (shallow water) or 1500 m (deep water) during the voyage to the SW of Tasmania (Hobart to Hobart).

All frequencies were logged continuously for the extent of the voyage, except on occasions when undertaking bathymetry mapping in shallow water on the shelf when the 38, 70 and 120 kHz frequencies (together or separately) were set to passive for to avoid interference with the EM710 echo sounder.

Data are stored in *.raw, *.bot and *.idx format at CSIRO. There are 1500 files totalling 138 GB of raw data in this dataset.

No processing has been conducted on this data.
