SSCN Segment 2-B: Bathymetry Survey in Western Eyre Marine Park

Western Eyre Marine Park bathymetry data collected by EGS onboard the RV Bold Explorer in April 2024 for the SUBCO Subsea Cable Network route survey. The dataset includes seabed features and shallow geology investigations from a subsequent geotechnical sampling programme. It is published by the Australian Ocean Data Network and is not intended for navigational purposes.

Use Cases

• Model seabed topography for cable route planning based on bathymetry survey.
• Identify potential seabed hazards for infrastructure based on seabed feature investigation.
• Analyze shallow geology for environmental impact assessments based on geotechnical sampling.
• Validate bathymetric survey methodologies based on detailed calibration procedures described.

Strengths

• Detailed calibration and verification of positioning and sensor systems performed on specific dates (17th-20th April 2024).
• Survey conducted within a defined protected area (Western Eyre Marine Park).
• Dataset includes multiple survey components: bathymetry, seabed features, and shallow geology.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic/temporal bias inherent to data_gov_au.
