This record describes scientific split-beam echosounder data collected on the RV Investigator voyage IN2024_T01, 'Transit Voyage: Fremantle to Hobart.' The primary objective of the voyage was the safe and timely transit of RV Investigator from Fremantle to Hobart in preparation for the following research voyage. During the transit various research projects were conducted, along with outreach, familiarisation and training activities. The voyage departed Fremantle on the 09 March and returned to Hobart on the 20 March. 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 1500 m, between Fremantle and Hobart. All frequencies were logged continuously for the extent of the voyage with the excpetion of the 70 kHz which was set to passive for the periods of focused seafloor mapping. While the 18 kHz was used and recorded for the voyage, it should not be used for quantitative analysis due to a damaged transducer channel. The transducer is planned to be replaced during the vessel's mid-life. Data are stored in .raw, .bot and *.idx format at CSIRO. There are 2161 files totalling 50.2 GB of raw data in this dataset. No processing has been conducted on this data. Additional information regarding this dataset is contained in the GSM data acquisition and processing report.
