SSCN Segment 2-B: Bathymetry Survey of Western Eyre Marine Park

Western Eyre Marine Park bathymetry data collected by EGS onboard the RV Bold Explorer in April 2024. The survey investigated seabed features and shallow geology along a proposed subsea cable route, followed by a geotechnical sampling program. The dataset is part of the SSCN cable route survey and is not for navigational use.

Use Cases

• Plan subsea cable routes based on detailed bathymetry and seabed feature data.
• Analyze seabed geology and morphology for marine park environmental assessments.
• Validate and calibrate marine survey equipment and methods based on documented procedures.
• Support geotechnical studies by integrating survey data with subsequent sampling results.

Strengths

• Survey procedures are documented with specific dates and locations, including Fremantle Port and offshore calibrations.
• Data collection focused on a specific marine park and cable route segment, providing targeted geospatial information.
• The survey included multiple phases: bathymetry investigation, seabed feature mapping, and geotechnical sampling.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic/temporal bias inherent to the specific survey period and location.
