Processed data are SV corrected, tide not corrected and edited using CARIS version 10.3.1 This record describes multibeam echosounder data collected on RV Investigator voyage IN2018_V08, The Balleny mantle plume: key role in Tasmania-Antarctic breakup?, which departed Hobart on the 27/12/2018 and returned to Hobart on the 10/01/2019. The voyage objectives was to identify/map seamounts of the Balleny seamount chain and dredge volcanic samples from the identified seamounts. The Kongsberg EM122 multibeam echosounder was used to acquire seafloor bathymetry, backscatter information and watercolumn backscatter in the Tasman Sea. The EM122 provides a 1 degree by 1 degree angular resolution. The echosounder's nominal frequency is 12 kHz. Data are stored in *.all raw format for bathymetry and backscatter and *.wcd format for watercolumn backscatter at CSIRO. There are 822 files totalling 42.7 GB of raw data in this dataset. Sound velocity profiles were applied to this data during data acquisition. Bathymetry data contained in *.all format are corrected for motion and position. Tide 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. Additional information regarding this dataset, including information on processing streams, is contained in the GSM data acquisition and processing report. Additional data products may be available on request.
