Helen's Rock Bathymetry Survey from 2013

Helen's Rock bathymetry data was acquired by Deakin University Marine Mapping lab in 2013. The survey was conducted onboard the Motor Vessel Yolla over one day on November 27, 2013, using a Kongsberg EM2040c instrument. The dataset is provided by the Australian Ocean Data Network.

Use Cases

• Modeling seafloor topography based on the bathymetric survey data.
• Analyzing underwater geological features based on the high-resolution sonar mapping.
• Supporting marine habitat research based on the detailed depth measurements.
• Creating nautical charts for scientific reference based on the geospatial data.

Strengths

• Data was collected using a specific, high-resolution instrument (Kongsberg EM2040c).
• Survey has a precise acquisition date (November 27, 2013).
• Data originates from a recognized academic institution (Deakin University Marine Mapping lab).

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 and file size are unknown, which may limit suitability assessment.
