Crowdy Head Offshore NSW Bathymetry and Backscatter Survey, 2021

The NSW Department of Planning and Environment acquired this multibeam survey data from the Research Vessel Bombora between 20/APR/2021 and 30/APR/2021. The dataset contains 32-bit floating point geotiff files of bathymetry and backscatter at a 5-meter resolution for the Crowdy Head Offshore area. Data processing utilized Hypack, R2Sonic GUI, POSView, POSPac, Qimera, and FMGT software.

Use Cases

• Modeling seabed topography based on high-resolution bathymetry data
• Classifying seabed types based on backscatter intensity data
• Establishing baseline environmental conditions for marine park management
• Supporting coastal infrastructure planning with detailed seafloor maps

Strengths

• Data was acquired using a R2Sonic 2022 multibeam sonar system, suggesting high technical quality
• Provides both bathymetry and backscatter layers at a consistent 5-meter resolution
• Survey methodology and processing are documented in publicly available standard operating procedures

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download
• Column-level documentation is absent; field semantics must be inferred after download
