This record describes multibeam echosounder data collected on RV Investigator voyage IN2024_E01, 'Trials and Calibrations' which departed Hobart on the 28th October and returned to Hobart on the 6th November 2024. The Kongsberg EM124 multibeam echosounder was used to acquire seafloor bathymetry, backscatter information and watercolumn backscatter. NOTE: The system was newly installed in Singapore as part of the vessel's mid-life refit and this voyage constituted the formal Sea Acceptance Test for the system. The EM124 provides a 1 degree by 1 degree angular resolution. The echosounder's nominal frequency is 12 kHz. Data are stored in .kmall raw format for bathymetry and backscatter and .kmwcd format for watercolumn backscatter at CSIRO. There are 130 files totalling 6.31 GB of raw data and 131 files totalling 12.5 GB of watercolumn data in this dataset. Sound velocity profiles were applied to this data during data acquisition. Bathymetry data contained in *.kmall format are corrected for motion and position. GPS tide was computed using the EGM2008 model and applied to the processed data. Processed data has had outliers removed. Additional information regarding this dataset, including further information on processing streams, is contained in the GSM data acquisition and processing report.
