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 IN2018_V02, "SOTS: Southern Ocean Time Series automated moorings for climate and carbon cycle studies southwest of Tasmania" and "Subantarctic Biogeochemistry of Carbon and Iron, Southern Ocean Time Series site" which departed Hobart on the 03 March 2018 and returned to Hobart briefly on 12 March and finally concluded on the 21 March 2018. The Simrad EK60 split beam echosounders, 18, 38, 70 120, 200 and 333 kHz were used to acquire acoustic backscatter data. The settings and monitoring were undertaken as part of a piggy back project, by Rudy Kloser, "Acoustic zooplankton and fish" . Data are stored in *.raw, *.bot and *.idx format at CSIRO. There are 3460 files totalling 65.6 GB of data in this dataset. Additional information regarding this dataset is contained in the GSM data acquisition and processing report.
