RV Investigator Voyage IN2020_V01 EK60 Echosounder Data

This record describes scientific split-beam echosounder data collected from the Marine National Facility (MNF) RV Investigator Voyage IN2020_V01, titled: “Development of William’s Ridge, Kerguelen Plateau: tectonics, hotspot magmatism, microcontinents, and Australia’s Extended Continental Shelf” between January 08 and March 06, 2020 departing from Henderson (WA) and returning back to Fremantle (WA).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 at Rig Seismic Seamount, Williams Ridge, Broken Ridge and on associated transits.. All frequencies were logged continuously for the extent of the voyage.Data are stored in *.raw, *.bot and *.idx format at CSIRO. There are 1330 files totalling 65.1 GB of raw data in this dataset.No processing has been conducted on this data.Additional information regarding this dataset is contained in the GSM data acquisition and processing report.
