Clarence Strait to Dundas Strait Bathymetry Survey, 2023

Geoscience Australia Data collected bathymetry data for the Australian Hydrographic Office between 4 July and 9 September 2023. The survey was conducted under the Hydroscheme Industry Partnership Program using Kongsberg EM2040 multibeam sonar systems. Data was processed and exported as a 30-meter resolution GeoTIFF grid.

Use Cases

• Modeling seafloor topography based on the 30-meter resolution bathymetric grid.
• Analyzing underwater features in the Clarence Strait to Dundas Strait region based on the described survey area.
• Supporting marine spatial planning and environmental studies based on high-resolution bathymetric data.
• Calibrating or validating other marine geospatial datasets based on the professionally acquired sonar data.

Strengths

• Data was acquired using professional-grade Kongsberg EM2040-07 and EM2040-P multibeam sonar systems.
• The final product is a high-resolution 30-meter grid, providing detailed seafloor elevation data.
• Survey has a defined temporal scope from 4 July 2023 to 9 September 2023.
• Data was processed using industry-standard QIMERA and BeamworX AutoClean software.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is explicitly not to be used for navigational purposes, restricting its primary application.
