Crowdy Head Offshore Bathymetry and Backscatter Survey, April 2021

April 2021 survey data collected by the NSW Department of Planning and Environment onboard the Research Vessel Bombora. The dataset contains 32-bit floating point geotiff files of bathymetry and backscatter in 5m resolution for the Crowdy Head Offshore area. It was created to provide a baseline dataset and map the spatial distribution of seabed types.

Use Cases

• Create high-resolution seabed habitat maps based on bathymetry and backscatter data.
• Analyze seabed morphology and slope for coastal engineering projects.
• Establish baseline environmental conditions for marine park management.
• Model underwater terrain for geological or hydrodynamic studies.

Strengths

• High-resolution 5-meter grid for detailed spatial analysis.
• Includes both bathymetry (depth) and backscatter (seabed hardness) data layers.
• Survey conducted over a defined 10-day period in April 2021.
• Processing methodology documented in a standard operating procedures document.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific survey area.
