This record describes scientific split-beam echosounder data collected on the RV Investigator voyage IN2022_T01, titled "Transit: Cairns to Darwin 2022." The voyage took place between September 11, 2022 and September 17, 2022 (AEST), departing from Cairns and returning to Darwin.

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 Cairns and Darwin. All frequencies were logged continuously for the extent of the voyage. The 70 and 120 kHz frequencies were set to passive for the periods of the voyage due to interference with the EM710. Data are stored in .raw, .bot and *.idx format at CSIRO. There are 496 files totalling 26.3 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.
