SSCN SEGMENT 2-B: Bathymetry Survey of Eastern Recherche Marine Park

April 2024 bathymetric data collected by EGS onboard the RV Bold Explorer for a subsea cable route survey. The dataset covers seabed features and shallow geology within the Eastern Recherche Marine Park off Western Australia. It was acquired by the Australian Ocean Data Network and is not intended for navigational use.

Use Cases

• Modeling seabed topography for subsea cable route planning based on the described bathymetry and seabed feature investigation.
• Analyzing shallow geology and seabed composition for environmental impact assessments, as suggested by the survey description.
• Calibrating and validating marine acoustic survey equipment using the documented calibration procedures for multibeam echosounders.
• Studying marine park bathymetry for habitat mapping and conservation planning within the confined survey area.

Strengths

• Data collection followed a documented calibration and verification process for DGPS, gyros, and multibeam echosounders on specific dates in April 2024.
• Survey scope is clearly defined to the Eastern Recherche Marine Park, providing focused geographic coverage.
• Dataset is part of a broader survey that included a subsequent geotechnical sampling program, suggesting contextual data may exist.

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 for large-scale analysis.
• The dataset carries a specific warning that it is not to be used for navigational purposes, limiting its application scope.
