In addition to the tasks at the SOTS site the voyage also recovered a Rintoul mooring that was deployed during IN2020_V05.\nThe Kongsberg EM122 multibeam echosounder was used to acquire seafloor bathymetry,  backscatter information and watercolumn backscatter during the voyage.\nThe EM122 provides a 1 degree by 1 degree angular resolution. The echosounder's nominal frequency is 12 kHz.\nData are stored in .all raw format for bathymetry and backscatter and .wcd format for watercolumn backscatter at CSIRO. There are 196 files totalling 11.1 GB of raw bathymetry & backscatter data, and 196 files totalling 8.5 GB of raw watercolumn data in this dataset.\nSound velocity profiles were applied to this data during data acquisition. Bathymetry data contained in *.all format are corrected for motion and position.\nTide corrections were not applied to the processed data. Processed data had outliers removed. Processed line data are available in *.gsf and ascii format, and processed bathymetry and backscatter grids in geotiff format.\nAdditional information regarding this dataset, including information on processing streams, is contained in the GSM data acquisition and processing report.
