SSCN SEGMENT 2-C: Bathymetry and Seabed Survey of Murray Marine Park

Bathymetry and seabed feature data were collected by EGS onboard the RV Bold Explorer in April 2024 for the SUBCO Subsea Cable Network (SSCN) cable route survey. The dataset covers a segment within the Murray Marine Park off the coast of Western Australia. A subsequent geotechnical sampling program was also executed as part of the broader survey.

Use Cases

• Modeling seabed topography for subsea cable route planning based on the described bathymetry survey.
• Analyzing seabed features and shallow geology for environmental impact assessments within the marine park.
• Calibrating or validating other marine geospatial datasets using the described multibeam echosounder (MBES) data.

Strengths

• Data collection followed a documented calibration and verification process for positioning and sensor systems between April 17-20, 2024.
• The survey scope is clearly defined, covering bathymetry, seabed features, and shallow geology along a proposed cable route.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• The description explicitly states the data is not to be used for navigational purposes.
