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

Bathymetry data collected during a subsea cable route survey within the Nelson Marine Park. The survey was conducted by EGS onboard the RV Bold Explorer, departing Fremantle Port in April 2024, and investigated seabed features and shallow geology. The dataset is provided by the Australian Ocean Data Network and was last updated in June 2026.

Use Cases

• Modeling seabed topography for cable route planning based on the bathymetric survey.
• Analyzing seabed features and shallow geology for environmental impact assessments.
• Calibrating marine navigation and mapping systems using the described sensor verification procedures.

Strengths

• Survey procedures are documented, including specific calibration dates (17th-20th April 2024) and sensor types.
• The dataset has a defined geographic scope confined to the Nelson Marine Park.
• Data was last updated on 2026-06-23 03:33:45.198742.

Limitations

• Row count and file size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The description explicitly states the data is not to be used for navigational purposes.
