| Summary: | Progress Code: completed Maintenance and Update Frequency: asNeeded Statement: Original field data. This record describes scientific split-beam echosounder data collected on the RV Investigator voyage IN2019_V02, titled 'SOTS: Southern Ocean Time Series automated moorings for climate and carbon cycle studies southwest of Tasmania; Subantarctic Biogeochemistry of Carbon and Iron, Southern Ocean Time Series site', which departed Hobart on the 14 March 2019 and returned to Hobart on the 5 April 2019. The Simrad EK60 split beam echosounders 18, 38, 70 120, 200 and 333 kHz were used to acquire acoustic backscatter data to a 1500 m range, around the southwest of Tasmania. All frequencies were logged continuously for the extent of the voyage. The frequencies were set to passive for periods of the voyage. Data are stored in *.raw, *.bot and *.idx format at CSIRO. There are 2,748 files totalling 91.5 GB of raw data in this dataset. No processing has been conducted on this data.
