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 arrived in Sydney on the 29 August 2016.

The Kongsberg EM122 multibeam echosounder was used to acquire seafloor bathymetry, backscatter information between Hobart and Sydney.

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 70 files totaling 2.25 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 have 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.
