SSCN Segment 2-C: Bathymetry Survey of Nelson Marine Park, April 2024

EGS conducted a bathymetric survey onboard the RV Bold Explorer for the SUBCO Subsea Cable Network (SSCN) Segment 2-C route within Australia's Nelson Marine Park in April 2024. The dataset includes data on seabed features and shallow geology, collected using multibeam echosounders and other sensors after calibration. This dataset is hosted by the Australian Ocean Data Network and is not intended for navigational purposes.

Use Cases

• Modeling seabed topography based on bathymetric survey data.
• Assessing geological hazards for subsea cable routing based on seabed feature investigation.
• Conducting marine habitat mapping based on bathymetry and seabed characteristics.
• Calibrating or validating other marine geospatial datasets based on the described sensor calibration procedures.

Strengths

• Data collection followed a documented calibration protocol for positioning and multibeam echosounder systems on April 19-20, 2024.
• Survey scope is clearly defined, covering bathymetry, seabed features, and shallow geology along a proposed cable route.
• Dataset is part of a managed national data network, the Australian Ocean Data Network.

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.
• Data may reflect geographic and temporal bias inherent to a single, focused survey in April 2024.
