Brief description

This record describes multibeam echosounder data collected on RV Investigator voyage IN2019_E01, 'Post-Dry Dock Calibration Trials' which departed Singapore on the 19th July 2019 and returned to Cairns on the 2nd August 2019. EM122 Calibration data was also collected on this voyage .

The Kongsberg EM122 multibeam echosounder was used to acquire seafloor bathymetry and backscatter information within Australia's EEZ in the Arafura sea, the Torres Strait and the Coral 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 85 files totalling 5.69 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.
