This record describes scientific split-beam echosounder data collected on the RV Investigator voyage IN2023_V06, titled: "Understanding Eddy Interactions and Their Impacts In the East Australian Current System." The voyage took place between October 9 and November 2, 2023, departing from Sydney (NSW) and returning to Sydney. The Simrad EK60 split beam echosounders for18kHz 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 1500m, around NSW/VIC coastal areas. All frequencies were logged continuously for the extent of the voyage. The 70kHz & 120kHz frequencies were set to passive for the periods of shallow mapping areas of the voyage. Data are stored in .raw, .bot and *.idx format at CSIRO. There are 394 files totalling 35.6 GB of raw data in this dataset. No post processing has been conducted on this data. Additional information regarding this dataset is contained in the GSM data acquisition and processing report. Additional data products may be available on request.
