Crowdy Head Offshore NSW Bathymetry and Backscatter Survey, 2021

Multibeam survey data acquired by the New South Wales government from April 20 to 30, 2021. The dataset contains 32-bit floating point geotiff files of bathymetry and backscatter in 5-meter resolution for the Crowdy Head Offshore area. It was collected using an R2Sonic 2022 multibeam sonar onboard the Research Vessel Bombora as part of the SeabedNSW program.

Use Cases

• Modeling seabed topography and slope based on high-resolution bathymetry data.
• Classifying seabed types and habitats based on backscatter intensity data.
• Establishing baseline environmental conditions for coastal monitoring programs.
• Supporting marine spatial planning and conservation area management.

Strengths

• Specific survey period from April 20 to April 30, 2021.
• High-resolution 5-meter grid for bathymetry and backscatter.
• Detailed processing methodology and standard operating procedures are documented and linked.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Explicitly states 'Not to be used for navigational purposes', limiting its application scope.
