Full description

This record describes scientific split-beam echosounder data collected on the RV Investigator voyage IN2019_V03, 2nd Indian Ocean Expedition Line which departed Fremantle on the 14/05/2019 and returned to Fremantle on the 14/06/2019.

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 in the area of the Indian Ocean, 110° E. All frequencies were logged continuously for the extent of the voyage. The frequencies were set to passive for the whole of the voyage.
Data are stored in *.raw, *.bot and *.idx format at CSIRO. There are 2626 files totalling 73.4 GB of raw data in this dataset.
