Full description

This record describes multibeam echosounder data collected on RV Investigator voyage IN2016_T02, transit from Hobart to Sydney which departed Hobart on the 25 August 2016 and returned to Sydney on the 29 August 2016.

The Kongsberg EM710 MKII multibeam echosounder was used to acquire seafloor bathymetry and backscatter information between Hobart and Sydney with a hydrographic survey performed near Flinders Island.

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 97 files totalling 11.9 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 except for the area of the hydrographic survey near Flinders Island. 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 further information on processing streams is contained in the GSM data acquisition and processing report. Additional data products may be available on request.
