Broome Bathymetry Survey for Echosounder Calibration at 0.5m Resolution

A high-resolution bathymetry surface created from a contracted national reference survey between Gantheaume Point and Talboys Rock, Broome, Western Australia. The survey was acquired for the Australian Hydrographic Office over two days in September 2020 using a Kongsberg EM 2040D multibeam echosounder. The processed data is provided as a 0.5m resolution, 32-bit floating point GeoTIFF grid in MSL, LAT, and Ellipsoid vertical datums.

Use Cases

• Calibrate multibeam echosounder systems based on the described reference survey purpose.
• Analyze seafloor topography and bathymetric features based on the 0.5m resolution grid.
• Model coastal and marine geomorphology near Broome, WA, based on the specified geographic area.
• Validate other bathymetric datasets using the high-resolution reference surface.

Strengths

• High-resolution 0.5m grid derived from a dedicated reference survey.
• Data processed using industry-standard Caris HIPS & SIPS software.
• Provides grids in three vertical datums: MSL, LAT, and Ellipsoid.
• Acquired with a specific Kongsberg EM 2040D multibeam system.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
