SSCN Segment 2-B: Great Australian Bight Marine Park Bathymetry Survey

Great Australian Bight Marine Park bathymetry data collected during a subsea cable route survey in April 2024. The survey, conducted by EGS onboard the RV Bold Explorer, investigated seabed features and shallow geology along a proposed cable route. A subsequent geotechnical sampling program was also executed.

Use Cases

• Modeling seabed topography for subsea cable routing based on bathymetric survey data.
• Identifying potential seabed hazards for marine infrastructure based on seabed feature investigation.
• Assessing geological conditions for marine construction based on shallow geology data.
• Supporting environmental impact assessments within marine parks based on geospatial survey data.

Strengths

• Data collection followed a documented calibration process for positioning and multibeam echosounder systems on specific dates.
• Survey scope is clearly defined to the Great Australian Bight Marine Park geographic area.
• The dataset is part of a broader survey investigating multiple seabed characteristics.

Limitations

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