SSCN SEGMENT 2-B: Bathymetry Survey of the Great Australian Bight Marine Park

EGS survey data collected from the RV Bold Explorer between 17th and 20th April 2024. This dataset captures bathymetry, seabed features, and shallow geology along a proposed subsea cable route within the Great Australian Bight Marine Park. The data is provided by Geoscience Australia and is not intended for navigational purposes.

Use Cases

• Modeling seabed topography for cable route planning based on bathymetry data.
• Identifying potential seabed hazards for infrastructure projects based on seabed feature investigation.
• Analyzing shallow geology for environmental impact assessments along the proposed route.
• Calibrating and validating marine survey equipment and methodologies based on the described calibration procedures.

Strengths

• Survey conducted with calibrated multibeam echosounder (MBES) and USBL systems, as detailed in the description.
• Data collection is confined to a specific, protected geographic area: the Great Australian Bight Marine Park.
• The survey included a subsequent geotechnical sampling programme, suggesting ground-truthing of geophysical data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset scale are unknown, which may limit suitability assessment.
• The description metadata is limited; actual data quality and completeness require manual inspection after download.
