SSCN Segment 2-B: Bathymetry Survey of South-west Corner Marine Park

A 2024 marine survey collected bathymetry, seabed feature, and shallow geology data along a proposed subsea cable route within the South-west Corner Marine Park. The survey was conducted by EGS onboard the RV Bold Explorer, with equipment calibration performed in Fremantle Port between April 17-20, 2024. This dataset is part of the SUBCO Subsea Cable Network (SSCN) cable route survey and is not for navigational use.

Use Cases

• Modeling seabed topography for cable route planning based on the bathymetry survey.
• Identifying potential seabed hazards for infrastructure projects based on the investigation of seabed features.
• Analyzing shallow subsurface geology for environmental or geotechnical assessments mentioned in the description.

Strengths

• Survey conducted with calibrated multibeam echosounder (MBES) and USBL systems, with specific calibration dates provided.
• Dataset is confined to a specific, named geographic area: the South-west Corner Marine Park.
• Detailed provenance includes specific vessel (RV Bold Explorer), survey company (EGS), and embarkation date (April 17, 2024).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and spatial resolution are unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to the single 2024 survey.
