Maintenance and Update Frequency: asNeeded Statement: Original field data. This record describes ME 70 scientific multibeam fisheries echosounder data collected on RV Investigator voyage IN2021_V01, "Quantifying krill abundance for krill monitoring and management off the Australian Antarctic Territory", which departed Hobart on the 29th January 2021 and returned to Hobart on the 24th March 2021 (AEST). The Simrad ME70 scientific multibeam echosounder acquired acoustic backscatter data through the water column to 300 metres. The echosounder's frequency range is from 70 kHz to 120 kHz. The ME70 logged continuously for the majority of the voyage. Data are stored in Simrad *.all raw format at CSIRO. There are 13,322 files totalling 891 GB 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.
