Helen's Rock Bathymetry Survey from 2013, Victoria Coast

Deakin University Marine Mapping lab collected this bathymetric survey over a single day in 2013. The data was acquired from the Motor Vessel Yolla using a Kongsberg EM2040c sonar system. Geoscience Australia provides the processed data with a caution that it is not intended for navigational purposes.

Use Cases

• Modeling seabed topography based on the bathymetric survey data.
• Analyzing underwater geological features from the sonar mapping.
• Supporting coastal and marine habitat research using the geospatial depth data.

Strengths

• Data was collected using a specific, modern sonar system (Kongsberg EM2040c).
• The survey has a precise acquisition date (27 November 2013).
• Data is provided by a national geological authority (Geoscience Australia).

Limitations

• The dataset description lacks column-level documentation, requiring field semantics to be inferred after download.
• Row count and data scale are unknown, which may limit suitability assessment.
• The single-day acquisition period provides a snapshot rather than temporal coverage.
