Progress Code: completed Maintenance and Update Frequency: asNeeded Statement: Original field data. This record describes ME 70 scientific multibeam fisheries echosounder data collected on 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 ME70 scientific multibeam echosounder acquired acoustic backscatter data through the water column using a configuration designed specifically for this voyage. The echosounder's frequency range is from 70 kHz to 120 kHz. The ME70 logged continuously for the extent of the voyage except during parts of the transit. Data are stored in Simrad *.all raw format at CSIRO. There are 16,350 files totalling 1.55 TB of raw data in this dataset. No processing has been conducted on this data. Additional information regarding this dataset, including the settings used, is contained in the GSM data acquisition and processing report. Additional data products may be available on request.
