RV Investigator Voyage IN2020_V06 EK80 Echosounder

This record describes scientific high-precision wide-band echosounder data collected on the RV Investigator voyage IN2020_V06, titled "Probing the Australian-Pacific Plate Boundary: Macquarie Ridge in 3-D." The voyage took place between October 8 and November 3, 2020 departing from Hobart (TAS) and arriving in Hobart (TAS).

The Simrad EK80 split beam echosounders 18, 38, 70 120, 200 and 333 kHz were used to acquire acoustic backscatter data to a range of 1,500 m, around Macquarie Island and from Hobart transit. All frequencies were logged for the extent of the voyage, except where required to turn off for operational requirements. The frequencies were set to active for the whole period of the voyage.

Data are stored in *.raw, *.bot and *.idx format at CSIRO. There are 818 files totalling 78.1 GB of raw data in this dataset.
