This record describes multibeam echosounder data collected on RV Investigator voyage IN2016_V05, "The Great Barrier Reef as a significant source of climatically relevant aerosol particles". The voyage departed Brisbane on 28th September 2016. Leg 1 ended on 11 October with a personnel transfer at Fitzroy Island. Leg 2 ended on 16 October with another personnel transfer at Magnetic Island, then the voyage ended in Brisbane on 24 October 2016.

The Kongsberg EM710 MKII multibeam echosounder was used to acquire seafloor bathymetry and backscatter information and watercolumn backscatter during most of the survey.

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 489 files totalling 393 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 has had outliers removed. Processed line data are available in *.gsf and ascii 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.
