Bass Strait Seafloor Bathymetry and Backscatter Survey, May-June 2018

Multibeam echosounder data collected by the RV Investigator during voyage IN2018_C01 from May 28 to June 8, 2018. The survey focused on the primary shipping route through Bass Strait near Wilson's Promontory to facilitate safe navigation. Data includes 372 files of raw bathymetry and backscatter (119 GB) and 241 files of raw watercolumn backscatter (269 GB), processed with motion, tide, and sound velocity corrections.

Use Cases

• Generate high-resolution nautical charts based on processed bathymetry grids.
• Analyze seafloor composition and texture based on backscatter intensity data.
• Model underwater acoustic propagation based on watercolumn backscatter information.
• Assess shipping route safety and identify potential hazards based on detailed seafloor mapping.

Strengths

• 372 files of raw bathymetry and backscatter data totalling 119 GB.
• 241 files of raw watercolumn data totalling 269 GB.
• Data has been processed with motion, position, tide, and sound velocity profile corrections.
• Processed data is available in multiple formats including GeoTIFF grids and ASCII.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
