Eastern Recherche Marine Park Bathymetry Survey for SSCN Cable Route

EGS survey vessel RV Bold Explorer collected bathymetry, seabed feature, and shallow geology data for the SSCN Segment 2-B cable route within the Eastern Recherche Marine Park. The survey team embarked in Fremantle, Australia on April 17, 2024, with equipment calibration and offshore operations conducted from April 19-20, 2024. Geoscience Australia Data published this dataset, which is not intended for navigational purposes.

Use Cases

• Plan subsea cable route placement based on bathymetry and seabed feature data.
• Analyze shallow geology for cable burial feasibility based on survey findings.
• Assess marine park seabed morphology for environmental impact studies.
• Validate acoustic survey equipment calibration procedures based on described methods.

Strengths

• Data collection includes specific calibration dates (April 17-20, 2024) and vessel departure details.
• Survey scope is clearly defined, covering bathymetry, seabed features, and shallow geology.
• Dataset is sourced from a recognized government organization, Geoscience Australia Data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and data volume are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific marine park survey area.
