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

Survey data collected onboard the RV Bold Explorer from Fremantle Port on April 17th, 2024. The dataset covers bathymetry, seabed features, and shallow geology along a proposed subsea cable route within the Great Australian Bight Marine Park. It was acquired by EGS for the SUBCO Subsea Cable Network (SSCN) project.

Use Cases

• Model seabed topography for cable route planning based on bathymetry data
• Identify potential seabed hazards based on described seabed features
• Analyze shallow geology for environmental impact assessments
• Validate multibeam echosounder (MBES) calibration procedures described in the survey

Strengths

• Data collection includes calibration and verification of DGPS and gyros on April 17-18, 2024
• Survey covers specific features: bathymetry, seabed features, and shallow geology
• Dataset is part of a broader geotechnical sampling programme mentioned in the description

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 not to be used for navigational purposes, limiting one potential application
