Solitary Islands Seabed Bathymetry and Backscatter Survey, 2022-2023

A bathymetry and backscatter survey of the Solitary Islands Gumbaynggirr Yaegl Marine Park was acquired by the NSW government between 31 Aug 2022 and 31 Jul 2023. The dataset contains 32-bit floating point geotiff files of bathymetry and backscatter in 5m resolution, processed using Hypack, R2Sonic GUI, and other software. This dataset is provided by the Australian Ocean Data Network and is not for navigational use.

Use Cases

• Modeling seabed topography based on the 5m resolution bathymetry data.
• Classifying seabed types based on the backscatter intensity data.
• Establishing a baseline for coastal habitat monitoring based on the survey's stated purpose.
• Analyzing spatial distribution of marine substrates for conservation planning.

Strengths

• Data was collected using a multibeam sonar (R2Sonic 2022) over a defined 11-month period.
• Provides high-resolution (5m) 32-bit geotiff files for both bathymetry and backscatter.
• Processing methodology and standard operating procedures are documented via a provided link.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total file size are unknown, which may limit suitability assessment.
