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

Multibeam echosounder data was collected in April 2024 for a subsea cable route survey within the Eastern Recherche Marine Park. The dataset is part of a broader survey conducted by EGS onboard the RV Bold Explorer, which included seabed feature investigation and a subsequent geotechnical sampling program. Data acquisition followed equipment calibration and verification at Fremantle Port, Australia.

Use Cases

• Modeling seabed topography for cable route planning based on bathymetry data.
• Identifying potential seabed hazards for infrastructure projects based on seabed feature investigation.
• Supporting marine park management and environmental assessments with detailed seafloor maps.

Strengths

• Data collection followed a documented calibration and verification process for positioning and sensor systems.
• Survey scope included both bathymetry and shallow geology investigation along a proposed cable route.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
