SSCN SEGMENT 2-B: Western Eyre Marine Park Bathymetry Survey (April 2024)

EGS survey data from the RV Bold Explorer details bathymetry, seabed features, and shallow geology along a proposed subsea cable route. The dataset covers a specific segment within the Western Eyre Marine Park off Australia's coast. Data acquisition and sensor calibration occurred between 17th and 20th April 2024, originating from Fremantle Port.

Use Cases

• Modeling seabed topography for cable route planning based on bathymetric survey data.
• Identifying potential seabed hazards for infrastructure projects based on seabed feature investigation.
• Analyzing shallow geological structures for environmental or geotechnical assessments.
• Calibrating marine survey equipment methodologies using documented calibration procedures.

Strengths

• Data collection followed a documented calibration protocol for positioning and multibeam echosounder systems.
• Survey includes multiple data layers: bathymetry, seabed features, and shallow geology.
• Specific temporal bounds are provided for the survey mobilization and calibration phases in April 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.
• The description notes this dataset is not to be used for navigational purposes, indicating potential accuracy limitations for that use case.
