Helen's Rock Bathymetry Survey from 2013, Victoria, Australia

Helen's Rock, Victoria, Australia, was surveyed for bathymetry by Deakin University Marine Mapping lab in a single day on November 27, 2013. The data was collected from the Motor Vessel Yolla using a Kongsberg EM2040c sonar system. The dataset is hosted by Geoscience Australia with a last update recorded in 2026.

Use Cases

• Modeling seabed topography based on the bathymetric survey data.
• Analyzing coastal geomorphology around Helen's Rock based on the sonar mapping.
• Supporting marine habitat mapping based on the detailed seafloor depth information.
• Providing a baseline for coastal erosion or sediment transport studies based on the 2013 survey snapshot.

Strengths

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

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.
• Row count is unknown, which may limit suitability assessment.
