Kongsberg EM710 MKII multibeam echosounder data captures seafloor bathymetry, backscatter, and watercolumn backscatter from a 2021 research voyage. The Australian Ocean Data Network provides 32 raw bathymetry files (12.2 GB) and 30 watercolumn files (39.7 GB) from the RV Investigator. Data collection occurred between November 20 and November 28, 2021, east of Tasmania and around Freycinet Marine Park.
Primary data is in proprietary *.all and *.wcd raw formats; processed grids (GeoTIFF) and line data (*.gsf) are more accessible. A detailed GSM data acquisition and processing report contains essential metadata for correct use.
