Portsea Hole Bathymetry Survey of Port Phillip Bay, 2018

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

Use Cases

• Model seabed topography based on bathymetry survey data.
• Analyze marine habitat features for conservation planning based on seafloor mapping.
• Support coastal engineering projects with detailed underwater terrain data from Port Phillip Bay.

Strengths

• Survey conducted with a specific, high-resolution sonar system (Kongsberg EM2040c).
• Data collection was focused over a defined two-day period (20-21 January 2018).
• Project has a clear institutional purpose (Parks Victoria marine park mapping).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to data_gov_au, being a single survey location.
