The echosounder's nominal frequency is 12 kHz.\nData are stored in .all raw format for bathymetry and backscatter and .wcd format for watercolumn backscatter at CSIRO. There are 715 files totalling 43.2 GB of raw bathymetry & backscatter data, and 715 files totalling 60.3 GB of raw watercolumn data in this dataset..\nSound velocity profiles were applied to this data during data acquisition. Bathymetry data contained in *.all format are corrected for motion and position.\nThe data have been reduced to approximate Mean Sea Level (MSL) using the Earth Gravitation Model 2008 (EGM2008) 1 arc-minute grid. Tide corrections were not applied to the processed data. Processed data had outliers removed. Processed line data are available in *.gsf and ascii format, and processed bathymetry and backscatter grids in geotiff format.\nAdditional information regarding this dataset, including information on processing streams, is contained in the GSM data acquisition and processing report.
