This record describes ME 70 scientific multibeam fisheries echosounder data collected from the Marine National Facility (MNF) RV Investigator Voyage IN2020_V08, titled "SOLACE - Southern Ocean Large Areal Carbon Export: quantifying carbon sequestration in subpolar and polar waters." The voyage took place between December 5, 2020 and January 16, 2021 departing from Hobart (TAS) and arriving in Hobart (TAS). The Simrad ME70 scientific multibeam echosounder acquired acoustic backscatter data through the water column to 200m. The echosounder's frequency range is from 70 kHz to 120 kHz. The ME70 logged sporadically for the extent of the voyage. Data is stored in Simrad *.raw format at CSIRO. There are 273 files totalling 41.2 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.
