This record describes scientific split-beam echosounder data collected on the RV Investigator voyage IN2019_E01, 'Post-Dry Dock Calibration Trials', which departed Singapore on the 19th July 2019 and returned to Cairns] on the 2nd August 2019. EK60 Calibration data was also collected on this voyage
The Simrad EK60 split beam echosounders 18, 38, 70 120, 200 and 333 kHz were used to acquire acoustic backscatter data to a range of 1500 m, within Australia's EEZ in the Arafura sea, the Torres Strait and the Coral Sea. All frequencies were logged continuously for the extent of the voyage within Australia's EEZ. Data are stored in *.raw, *.bot and *.idx format at CSIRO. There are 173 files totalling 15.9 GB of raw data in this dataset.
Processing has been conducted on the calibration data only.
