SSCN Segment 2-B: Eastern Recherche Marine Park Bathymetry Survey

Bathymetry data was collected along a proposed subsea cable route within the Eastern Recherche Marine Park off Western Australia. The survey was conducted by EGS onboard the RV Bold Explorer in April 2024, involving multibeam echosounder calibration and seabed feature investigation. This dataset is provided by the Australian Ocean Data Network and is not for navigational use.

Use Cases

• Modeling seabed topography for cable route planning based on the bathymetry survey.
• Identifying potential seabed hazards for infrastructure projects based on the investigation of seabed features.
• Analyzing shallow geology for environmental impact assessments based on the survey's geological investigation.
• Calibrating marine survey equipment methodologies based on the described DGPS and MBES calibration procedures.

Strengths

• Survey procedures are documented with specific dates and calibration steps, such as DGPS verification on April 17-18, 2024.
• Data collection is confined to a specific, protected geographic area: the Eastern Recherche Marine Park.
• The dataset is part of a broader, professionally executed cable route survey involving a subsequent geotechnical sampling program.

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, restricting its application scope.
