Murray Marine Park Bathymetry Survey from 2024 Cable Route Investigation

Murray Marine Park bathymetry data was acquired in April 2024 during the SSCN Subsea Cable Network survey. The dataset results from a marine survey using multibeam echosounders to investigate seabed features and shallow geology along a proposed cable route. It is provided by Geoscience Australia Data.

Use Cases

• Model seabed topography and features using multibeam echosounder-derived bathymetry data.
• Analyze shallow geology characteristics along the proposed SSCN cable route for infrastructure planning.
• Integrate bathymetry and seabed feature data for marine habitat mapping within the Murray Marine Park.

Strengths

• Data originates from a dedicated marine survey vessel, the RV Bold Explorer, using calibrated multibeam echosounder systems.
• Survey procedures included equipment testing, DGPS verification, and offshore calibration of shallow and deep water systems.
• Focus area is the defined Murray Marine Park, providing geospatial context for the bathymetric measurements.

Limitations

• Specific data dimensions (row count, column count, spatial resolution) and sample data are unavailable for assessment.
• The dataset is explicitly not intended for navigational purposes, limiting its operational use case.
• Data volume, file structure, and processing level within the ZIP archive are unknown.
