Great Australian Bight Marine Park Bathymetry Survey

A 2024 marine survey dataset from the Great Australian Bight Marine Park, capturing bathymetry, seabed features, and shallow geology. The survey was conducted by EGS aboard the RV Bold Explorer for the SSCN cable route project. Data acquisition occurred in April 2024, following sensor calibration and testing.

Use Cases

• Model seabed topography and identify underwater hazards using bathymetry data for submarine cable route planning.
• Analyze seabed features to understand benthic habitats and geological structures within the marine park.
• Integrate shallow geology data with bathymetric measurements to assess sediment stability for infrastructure projects.
• Calibrate and validate remote sensing bathymetry models using in-situ multibeam echosounder survey data.

Strengths

• Data collected in April 2024, providing recent measurements.
• Includes calibration details for positioning (DGPS, gyros) and sensors (MBES, USBL) performed before survey.
• Covers a defined area within the Great Australian Bight Marine Park.

Limitations

• Exact spatial extent, row count, and data resolution are unknown.
• Dataset is explicitly not for navigational purposes, limiting operational applications.
• Sample data and column definitions are unavailable, complicating initial analysis.
