Portsea Hole Bathymetry Survey of Port Phillip Bay, 2018

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

Use Cases

• Modeling seabed topography based on bathymetric survey data
• Analyzing marine park habitats based on seafloor mapping
• Conducting coastal or marine geological research based on high-resolution sonar data

Strengths

• Data collected with a specific high-resolution multibeam sonar system (Kongsberg EM2040c)
• Survey conducted over a defined two-day period (20-21 January 2018)
• Part of a systematic project to map all marine parks in Victorian waters

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
