AHO Torres Strait Bathymetry Survey: 0.5m Resolution Reference Surfaces

Bathymetric reference surfaces for the Torres Strait region were acquired for the Australian Hydrographic Office on 12 December 2021. The survey was conducted between Goods Island and Tuesday Island using a Kongsberg EM2040D multibeam echosounder. The processed data is provided as 0.5m resolution GeoTIFF grids in three vertical datums.

Use Cases

• Calibrate multibeam echosounder systems based on the described reference survey purpose
• Analyze seabed topography in the Torres Strait based on high-resolution bathymetry grids
• Compare vertical datum transformations based on the availability of MSL, LAT, and Ellipsoid grids

Strengths

• High-resolution 0.5m grid cells for detailed bathymetric analysis
• Survey conducted with a specific Kongsberg EM2040D instrument
• Data processed using QPS Qimera software, suggesting standardized processing

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
• Row count is unknown, which may limit suitability assessment
