RV Investigator Voyage IN2022_V09 EK60/EK80 Echosounder

This record describes scientific split-beam echosounder data collected on the RV Investigator voyage IN2022_V09, titled "Valuing Australia’s new Gascoyne Marine Park." The voyage took place between 0000 November 19, 2022 and 0700 December 19, 2022 (UTC), departing from Fremantle and returning to Fremantle.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 [range] m, throughout the voyage including within the Gascoyne and Ningaloo Marine Parks. All frequencies were logged continuously for the extent of the voyage. The 38 & 70 were periodically set to passive for the during the voyage to optimise MBES seabed mapping data quality.Data are stored in *.raw, *.bot and *.idx format at CSIRO.
