The primary objectives were testing the Giant Piston and Kasten Corer as well as the Deep Towed Camera. The voyage departed Hobart PW04 on the 30/11/2021 and returned to Hobart PW04 on the 08/12/2021.\nThe Kongsberg EM122 multibeam echosounder was used to acquire seafloor bathymetry,  backscatter information and watercolumn backscatter in the region of South East Tasmania.\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 161 files totalling 11.96 GB of raw 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 applied to the processed data using RTK/GPS height and the EGM2008 geoid model in Caris. 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.
