Full description

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 EM122 multibeam echosounder was used to acquire seafloor bathymetry, backscatter and water column information in deep water which was only possible for a short while on this voyage.
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 *.wcd for water column data at CSIRO. There are 140 files totalling 12.9 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 is available in *.gsf and ascii 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.
