Portsea Hole Bathymetry Survey of Port Phillip Bay, 2018

Bathymetry data for the Portsea Hole area of Port Phillip Bay, acquired over two days in January 2018. The survey was conducted by Deakin University Marine Mapping lab for a Parks Victoria project to map marine parks in Victorian state waters. Data was collected using a Kongsberg EM2040c sonar system from the Motor Vessel Yolla.

Use Cases

• Modeling seabed topography based on bathymetric survey data.
• Supporting marine park management and conservation planning based on mapped seafloor features.
• Analyzing underwater geological formations in a specific coastal region.

Strengths

• Survey was conducted with a specific, high-resolution instrument (Kongsberg EM2040c).
• Data has a precise temporal scope, collected on 20-21 January 2018.
• Project purpose is clearly stated as part of a marine park mapping initiative.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
