SSCN Segment 2-B: Great Australian Bight Marine Park Bathymetry Survey

EGS conducted a bathymetry, seabed feature, and shallow geology survey onboard the RV Bold Explorer in April 2024. The dataset covers a segment of the proposed Subsea Cable Network route within the Great Australian Bight Marine Park. Data acquisition involved multibeam echosounder systems calibrated and verified during the survey period.

Use Cases

• Modeling seabed topography for subsea cable route planning based on the bathymetry survey.
• Identifying potential seabed hazards for marine infrastructure based on the investigation of seabed features.
• Analyzing shallow geological structures for environmental assessments based on the described survey scope.

Strengths

• Survey involved specific calibration of DGPS, gyros, and multibeam echosounders on April 17-20, 2024.
• Dataset is confined to the Great Australian Bight Marine Park, providing focused geographic coverage.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
