Progress Code: completed Maintenance and Update Frequency: asNeeded Statement: Original field data. This record describes scientific splilt-beam echosounder data collected on RV Investigator voyage IN2016_v05, "The Great Barrier Reef as a significant source of climatically relevant aerosol particles." The voyage departed Brisbane on 28th September 2016. Leg 1 ended on 11 October with a personnel transfer at Fitzroy Island. Leg 2 ended on 16 October with another personnel transfer at Magnetic Island, then the voyage ended in Brisbane on 24 October 2016. The Simrad EK60 split beam echosounders, 18, 38, 120, 200 and 333 kHz were used to acquire acoustic backscatter data to a range of 250 or 1500 m. The frequencies were logged continuously for the extent of the voyage. The 70 KHz frequency was set to passive for the whole of the voyage. Data are stored in *.raw, *.bot and *.idx format at CSIRO. There are 1455 files totalling 70.9 GB of raw data in this dataset. No processing has been conducted on this data.
