This record describes scientific split-beam echosounder data collected on the RV Investigator voyage IN2016_V03, 'Monitoring Ocean Change and Variability along 170° W from the ice edge to the equator', which departed Hobart on the 26 April 2016 and returned to Lautoka, Fiji on the 30 June 2016. There was a port call at Wellington, New Zealand, 26 - 27 May for some science personnel change; this resulted in two "legs" of the voyage therefore Leg 1 is 26 April - 26 May 2016, and Leg 2 27 May - 30 June 2016. During Leg 1 the EK60 was predominately set to passive on all frequencies except for the 18 kHz which was run to full ocean depth as redundancy to the EM122 depth for CTD casts. The EK60 was also turned on with each individual frequency during transit to thoroughly test the interaction between the individual frequencies of EK60 and each of the ADCP’s. The EK60 was not run at all on Leg 2 as it was thought that it could cause interference with the ADCP data. Data are stored in .raw, .bot and *.idx format at CSIRO. There are 1494 files totalling 63.1 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. Additional data products may be available on request.
