Lacepede Channel Bathymetry Survey, 30m Resolution (2021)

The Lacepede Channel bathymetry survey was acquired for the Australian Hydrographic Office (AHO) between 19 May 2021 and 22 September 2021. Fugro conducted the survey using a Kongsberg EM2040 Mk II sonar system, with data processed in Caris Hips & Sips and exported as a 30-meter resolution GeoTIFF. This dataset is provided by Geoscience Australia Data.

Use Cases

• Modeling seafloor topography and slope based on the 30-meter resolution bathymetric grid.
• Analyzing underwater features in Lacepede Channel, Western Australia, based on the described survey area.
• Integrating bathymetric data with other marine datasets for habitat mapping, based on the geospatial format.
• Assessing changes in coastal bathymetry over time, based on the specific 2021 acquisition period.

Strengths

• Data was acquired using a specific, high-resolution sonar system (Kongsberg EM2040 Mk II).
• The final product is a 30-meter resolution grid, providing a defined level of spatial detail.
• Survey has a precise temporal coverage from 19 May 2021 to 22 September 2021.

Limitations

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