Western Eyre Marine Park Bathymetry Survey from RV Bold Explorer

Bathymetric data was acquired in April 2024 for the SSCN Subsea Cable Network route within the Western Eyre Marine Park. The survey was conducted by EGS onboard the vessel RV Bold Explorer, investigating seabed features and shallow geology. This dataset is part of a broader cable route survey and is not intended for navigational use.

Use Cases

• Analyze bathymetry point clouds to model seafloor topography for submarine cable engineering.
• Map seabed features identified by the survey to assess geological hazards along the proposed cable route.
• Integrate shallow geology investigation data with bathymetry to understand sediment composition for environmental impact studies.
• Use multibeam echosounder (MBES) data to create high-resolution digital elevation models of the marine park seafloor.

Strengths

• Data collection followed a detailed calibration protocol for DGPS, gyros, and multibeam echosounders on April 19-20, 2024.
• Survey scope includes bathymetry, seabed features, and shallow geology, providing multiple data layers for analysis.
• Dataset is managed and published by the authoritative Australian Ocean Data Network.

Limitations

• Specific data volume (row count, file size) and column schema are not provided in the description.
• Data is confined to a single geographic area (Western Eyre Marine Park) and a short temporal window (April 2024).
• The raw description notes this data is not to be used for navigational purposes, indicating potential accuracy limitations for safety-critical applications.
