SSCN SEGMENT 2-B: Bathymetry Survey of South-west Corner Marine Park

Bathymetry and seabed feature data acquired during the SSCN Subsea Cable Network route survey. The survey was conducted by EGS onboard the RV Bold Explorer in April 2024, focusing on the South-west Corner Marine Park. A subsequent geotechnical sampling program was also executed.

Use Cases

• Modeling seabed topography for cable route planning based on the described bathymetry survey.
• Analyzing shallow geology and seabed features for environmental impact assessments.
• Calibrating and verifying multibeam echosounder (MBES) systems using the described calibration procedures.

Strengths

• Data collection followed a documented calibration and verification process for positioning and sensor systems.
• Survey scope is clearly defined, covering bathymetry, seabed features, and shallow geology along a proposed route.

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.
