Clarence Strait to Dundas Strait Bathymetry Survey, 30m Resolution (2023)

A 30-meter resolution bathymetric grid of the seafloor in Clarence Strait to Dundas Strait, Australia. The survey was acquired for the Australian Hydrographic Office between 4 July and 9 September 2023 using Kongsberg EM2040 multibeam sonar systems. Data was processed with QIMERA and BeamworX AutoClean software and exported as a 32-bit floating point GeoTIFF.

Use Cases

• Modeling seafloor topography and geomorphology based on high-resolution bathymetric data.
• Analyzing underwater terrain for marine habitat mapping based on the detailed depth information.
• Supporting marine spatial planning and environmental assessments based on the defined survey area.

Strengths

• Data was collected with high-resolution Kongsberg EM2040 multibeam sonar systems.
• The final product is a 30-meter resolution grid, providing detailed spatial coverage of the survey area.
• Processing utilized industry-standard software (QIMERA and BeamworX AutoClean).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for certain analyses.
• The description explicitly states the dataset is not to be used for navigational purposes.
