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

A 2024 bathymetric survey conducted by EGS onboard the RV Bold Explorer for the SUBCO Subsea Cable Network (SSCN) cable route. The dataset covers seabed features and shallow geology within the Nelson Marine Park, with calibration activities performed in Fremantle Port between April 17-20, 2024. The data is provided by Geoscience Australia and is not for navigational use.

Use Cases

• Modeling seabed topography for subsea infrastructure planning based on the described bathymetry and seabed feature investigation.
• Analyzing shallow geology along a proposed cable route based on the survey's stated objectives.
• Calibrating marine survey equipment methodologies based on the detailed description of DGPS, gyro, and MBES calibration procedures.

Strengths

• Survey methodology is described in detail, including specific calibration dates (April 17-20, 2024) and equipment (MBES, USBL).
• Spatial coverage is explicitly confined to the Nelson Marine Park.
• Data provenance is clear, citing the survey vessel RV Bold Explorer and organization EGS.

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.
• The description metadata is limited to the survey overview; actual data quality and resolution require manual inspection.
