SSCN SEGMENT 2-C: Bathymetry and Seabed Survey in Nelson Marine Park

A 2024 marine survey conducted by EGS onboard the RV Bold Explorer for the SUBCO Subsea Cable Network (SSCN) cable route. The dataset focuses on bathymetry, seabed features, and shallow geology within the Nelson Marine Park, Australia. It includes data from multibeam echosounder (MBES) and USBL systems calibrated in April 2024.

Use Cases

• Modeling seabed topography for submarine cable route planning based on bathymetry data.
• Identifying potential seabed hazards for infrastructure projects based on seabed feature investigation.
• Analyzing shallow geology for marine park environmental baselines mentioned in the survey description.

Strengths

• Data collection followed a documented calibration process for positioning and multibeam systems on April 19-20, 2024.
• Survey scope includes multiple data layers: bathymetry, seabed features, and shallow geology.

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.
