This record describes multibeam echosounder data collected on RV Investigator voyage IN2016_V06, 'Sustained monitoring of the EAC: mass, heat and freshwater transports' which departed Brisbane on the 29th October 2016 and returned to Brisbane on the 13th November 2016.

The Kongsberg EM710 MKII multibeam echosounder was used to acquire seafloor bathymetry and backscatter information between Brisbane and the Brisbane Seamounts.

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 45 files totalling 4.8 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 applied to the processed data. Processed data has 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 further information on processing streams, is contained in the GSM data acquisition and processing report. Additional data products may be available on request.
