RV Investigator Voyage IN2018_E02 EM122 Multibeam Echosounder Data
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 EM122 multibeam echosounder was used to acquire seafloor bathymetry, backscatter information [and watercolumn backscatter] around south eastern Tasmania.
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 68 files totalling 1.7 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 this was for calibration testing.
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.
