SSCN Segment 2-B: Bathymetry and Seabed Features in the Great Australian Bight Marine Park

EGS collected this bathymetry dataset during the SSCN subsea cable route survey onboard the RV Bold Explorer in April 2024. The survey investigated seabed features and shallow geology within the Great Australian Bight Marine Park. The dataset is provided by the Australian Ocean Data Network and was last updated in April 2026.

Use Cases

• Modeling seabed terrain for subsea cable route planning based on bathymetric survey data.
• Identifying potential seabed hazards for marine construction based on the investigation of seabed features.
• Analyzing shallow geological structures for environmental or geotechnical assessments based on the survey's scope.

Strengths

• Data collection followed a documented calibration and verification process for positioning and sensor systems on specific dates in April 2024.
• Survey scope is clearly defined, covering bathymetry, seabed features, and shallow geology for a specific marine park area.

Limitations

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