Portsea Hole Bathymetry Survey in Port Phillip Bay, 2018

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

Use Cases

• Model seabed morphology based on bathymetry data mentioned in the description
• Analyze marine park habitats based on seafloor depth and features
• Support coastal engineering and navigation safety assessments based on detailed underwater topography
• Monitor changes in seabed structure over time using the 2018 survey as a baseline

Strengths

• Data was collected using a Kongsberg EM2040c multibeam sonar system, which suggests high-resolution mapping.
• Survey was conducted over two specific days (20/01/2018-21/01/2018), providing a precise temporal snapshot.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
