SSCN Segment 2-C: Bathymetry Survey of Nelson Marine Park

Bathymetry and seabed feature data were collected by EGS onboard the RV Bold Explorer for a subsea cable route survey in April 2024. The survey area is confined to the Nelson Marine Park in Australia. The dataset is part of a broader investigation that included shallow geology and a subsequent geotechnical sampling program.

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.
• Analyzing shallow geology for environmental impact assessments along the proposed route.
• Calibrating marine survey equipment using documented calibration procedures from April 2024.

Strengths

• Survey conducted with calibrated multibeam echosounder (MBES) and USBL systems.
• Specific calibration and verification dates are documented (17th-20th April 2024).
• Dataset is part of a broader survey that included geotechnical sampling.

Limitations

• Dataset is not to be used for navigational purposes, limiting its application scope.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
