SSCN SEGMENT 2-B: Bathymetry and Seabed Survey in Eastern Recherche Marine Park

Bathymetry and seabed feature data were collected during a survey for the SUBCO Subsea Cable Network (SSCN) cable route. The survey was conducted by EGS onboard the RV Bold Explorer in April 2024, focusing on the Eastern Recherche Marine Park off Western Australia. The dataset includes results from multibeam echosounder (MBES) investigations and a subsequent geotechnical sampling program.

Use Cases

• Modeling seabed topography for subsea infrastructure planning based on the bathymetry survey.
• Identifying potential seabed hazards for cable laying based on the investigation of seabed features.
• Analyzing shallow geology for environmental impact assessments based on the described survey scope.

Strengths

• Survey methodology is documented, including specific calibration dates (April 17-20, 2024) and equipment used (multibeam echosounder, USBL).
• Geographic scope is precisely confined to the Eastern Recherche Marine Park.

Limitations

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