This record describes scientific split-beam echosounder data collected on the RV Investigator voyage IN2019_V01, The availability of Antarctic krill to large predators and their role in biogeochemical recycling in the Southern Ocean which departed Hobart on the 19th January, 2019 and returned to Hobart on the 5th of March, 2019. 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 during the transit to/from the survey area, and a range of 700m while within the survey area in Antarctic waters. All frequencies were logged continuously for the extent of the voyage. A cold water calibration was performed at the Antarctic survey site, with the new calibration values applied to the dataset between 25 January and 27 February. Transit data were logging using calibration values from Hobart in June 8, 2018. Data are stored in *.raw, *.bot and *.idx format at CSIRO. There are 11,511 files totalling 214 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.
