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

April 2024 survey data collected by EGS onboard the RV Bold Explorer for the SUBCO Subsea Cable Network (SSCN) route. The dataset includes bathymetry, seabed features, and shallow geology investigations within the Great Australian Bight Marine Park, with a subsequent geotechnical sampling program. It is published by the Australian Ocean Data Network.

Use Cases

• Modeling seabed topography for cable route planning based on bathymetry data
• Identifying potential seabed hazards for infrastructure projects based on seabed feature investigation
• Analyzing shallow geology for environmental impact assessments mentioned in the survey description

Strengths

• Data collection followed a documented calibration process for positioning and multibeam echosounder systems on April 19-20, 2024
• Survey scope is clearly defined to the Great Australian Bight Marine Park geography

Limitations

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