This record describes multibeam echosounder data collected on RV Investigator voyage IN2018_E02, titled 'MNF Trials and Calibrations' which departed Hobart on the 3rd of September 2018 and returned to Hobart on the 9th of September 2018. The Kongsberg EM710 multibeam echosounder was used to acquire seafloor bathymetry and backscatter information around south eastern Tasmania. The EM710 provides a 0.5° by 1° transmit and receive angular resolution respectively. The echosounder's nominal frequency range is from 70 to 100 kHz. Data are stored in *.all raw format for bathymetry and backscatter at CSIRO. There are 97 files totalling 15.4 GB of raw data in this dataset. Multibeam bathymetry calibrations were performed on this trial. Tide corrections were not applied to the processed data. Processed data had outliers removed. Processed line data is not available as they were trials for calibration. 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.
