SI 1027: Bathymetry of Clarence Strait to Dundas Strait

Clarence Strait to Dundas Strait bathymetry was acquired for the Australian Hydrographic Office between 4 July 2023 and 9 September 2023. The data was collected using Kongsberg EM2040 multibeam sonar systems and processed into a 30-meter resolution, 32-bit floating point GeoTIFF grid. This dataset is part of the Hydroscheme Industry Partnership Program for offshore mapping.

Use Cases

• Seafloor morphology analysis based on high-resolution bathymetric grids.
• Habitat mapping for marine ecosystems using detailed depth data.
• Supporting geological and geophysical research in the survey area.
• Informing coastal and offshore infrastructure planning with bathymetric models.

Strengths

• Data has a specific and recent acquisition period from 4 Jul 2023 to 9 Sep 2023.
• High-resolution 30-meter grid derived from Kongsberg EM2040 multibeam sonar.
• Processed with industry-standard software (QIMERA and BeamworX AutoClean).

Limitations

• Metadata is incomplete: column names, row counts, file size, and license are not provided.
• Dataset is explicitly not for navigational purposes, limiting its operational use.
• Conflicting 'last updated' dates (2026-05-05 and 2026-04-04) create provenance uncertainty.
