Cape Leeuwin Bathymetry Survey at 30m Resolution (2022-2023)

Bathymetry data for an area off Cape Leeuwin, Western Australia, was acquired for the Australian Hydrographic Office. The survey was conducted from 5 December 2022 to 4 April 2023 by MMA Offshore onboard the MV Mermaid Searcher. Data was processed into a 30-meter resolution GeoTIFF grid using a Kongsberg EM2040P multibeam sonar and CARIS HIPS and SIPS software.

Use Cases

• Modeling seafloor topography based on the 30-meter resolution bathymetric grid.
• Analyzing coastal and marine geomorphology in the Cape Leeuwin region.
• Supporting marine spatial planning and environmental impact assessments using the high-resolution survey data.
• Creating base maps for oceanographic research based on the processed sonar data.

Strengths

• Data was acquired using a Kongsberg EM2040P multibeam sonar, a specific high-precision instrument.
• The final product is a 30-meter resolution, 32-bit floating point GeoTIFF grid.
• Survey has a defined temporal coverage from 5 December 2022 to 4 April 2023.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total file size are unknown, which may limit suitability assessment.
• The description explicitly states the dataset is not to be used for navigational purposes, limiting its primary application.
