Cape Leeuwin Bathymetry Survey: 30m Resolution Seafloor Data from 2022-2023

Bathymetry data for Cape Leeuwin, Western Australia, acquired by the Australian Hydrographic Office. The survey was conducted from 5 December 2022 to 4 April 2023 using a Kongsberg EM2040P multibeam echosounder. The processed dataset is a 30-meter resolution, 32-bit floating point GeoTIFF grid of the survey area.

Use Cases

• Modeling seafloor topography and slope based on the 30m resolution bathymetry grid.
• Analyzing coastal erosion or sediment transport patterns near Cape Leeuwin based on the detailed seafloor data.
• Creating nautical charts for scientific or planning purposes based on the high-resolution survey data.
• Integrating bathymetric data with other marine datasets for habitat mapping or resource assessment.

Strengths

• Data was acquired using a specific, high-resolution instrument (Kongsberg EM2040P multibeam echosounder).
• The final product is a processed 30-meter resolution grid, providing detailed spatial coverage.
• Survey has a defined temporal range from 5 December 2022 to 4 April 2023.

Limitations

• Description metadata is limited; actual data quality, coordinate reference system, and vertical datum require manual inspection after download.
• Row count and file size are unknown, which may limit suitability assessment for large-scale processing.
• The dataset is explicitly not to be used for navigational purposes, limiting its application scope.
