Processed data are SV corrected, tide not corrected and edited using CARIS version 10.3.8 This record describes multibeam echosounder data collected on RV Investigator voyage IN2021_V01, titled: "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 Kongsberg EM710 MKII multibeam echosounder was used to acquire seafloor bathymetry, backscatter information and watercolumn backscatter for only a short duration at the beginining of the voyage, followed by two short periods to assess mooring deployment locations. Mooring deployment site surveys carried out with the EM710 MKII were in the vicinity of the Antarctic shelf-break region with locations of approx. 66°57.2'S, 75°00.5'E & 66°32'S, 62°13'E. The EM710 MKII provides a 0.5° by 1° transmit and receive angular resolution respectively. The echosounder's nominal frequency range is from 40 to 100 kHz. Data are stored in *.all raw format for bathymetry and backscatter and *.wcd format for watercolumn backscatter at CSIRO. There are 47 files totalling 15.82GB 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. The data have been reduced to approximate Mean Sea Level (MSL) using the Earth Gravitation Model 2008 (EGM2008) 1 arc-minute grid. Tide corrections were not applied to the processed data. Processed data has 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 further information on processing streams, is contained in the GSM data acquisition and processing report. Additional data products may be available on request.
