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, acquired for the Australian Hydrographic Office. The survey was conducted from 4 July to 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 slope based on the 30m resolution bathymetric grid.
• Analyzing underwater geological features in the Clarence Strait to Dundas Strait area.
• Supporting marine habitat mapping and environmental studies using high-resolution depth data.
• Providing foundational data for coastal and maritime planning, excluding navigational use.

Strengths

• High-resolution 30-meter grid derived from Kongsberg EM2040 multibeam sonar.
• Specific acquisition period from 4 July to 9 September 2023.
• Data processed with industry-standard QIMERA and BeamworX AutoClean software.

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.
