Solitary Islands Marine Park Bathymetry and Backscatter Survey (2022-2023)

31 Aug 2022 to 31 Jul 2023 survey acquired by the NSW government onboard the RV Bombora using a multibeam sonar. The dataset provides 5m resolution geotiff files of bathymetry and backscatter for the Solitary Islands Gumbaynggirr Yaegl Marine Park area. It was created as a baseline dataset to map the spatial distribution of seabed types under the SeabedNSW program.

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 marine park management based on the spatial distribution mapping purpose.
• Integrating with other marine spatial data based on the geotiff format and geographic coordinates.

Strengths

• Data was collected over an 11-month period from 31 Aug 2022 to 31 Jul 2023, providing temporal context.
• Processed to 5-meter spatial resolution, offering detailed spatial data.
• Derived from a specific multibeam sonar system (R2Sonic 2022) with documented standard operating procedures.

Limitations

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