Full description

This record describes scientific split-beam echosounder data collected on the RV Investigator voyage IN2022_V08, titled "Biodiversity Assessment of Australia’s Indian Ocean Territories" which departed Darwin on September 30 and returned to Fremantle on November 3, 2022. This was a continuation of voyage IN2021_v04.

The Simrad EK60 split beam echosounders for 18 kHz 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) between Darwin and Fremantle.

All frequencies were logged continuously for the extent of the voyage, except on occasion around Cocos (Keeling) Island and Muirfield Seamount when the 70 and 120 kHz frequencies were set to passive to avoid interference with the EM710 when conducting shallow multibeam bathymetry surveys.

Data are stored in *.raw, *.bot and *.idx format at CSIRO. There are 2138 files totalling 149 GB of raw data in this dataset.

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