Portsea Hole Bathymetry Survey in Port Phillip Bay, 2018

Deakin University Marine Mapping lab collected this bathymetry data over two days in January 2018 using a Kongsberg EM2040c sonar system. The survey was conducted from the Motor Vessel Yolla as part of a Parks Victoria project to map marine parks in Victorian state waters. Data is provided in a ZIP file format and is not intended for navigational purposes.

Use Cases

• Modeling seafloor topography based on high-resolution sonar survey data.
• Analyzing marine park habitats using detailed bathymetric maps.
• Conducting coastal geomorphology research based on the specific survey of Portsea Hole.
• Supporting marine conservation planning with spatially explicit seafloor data.

Strengths

• Data was collected using a specific, high-resolution Kongsberg EM2040c multibeam echosounder.
• Survey has precise temporal coverage from January 20 to 21, 2018.
• Project purpose is clearly stated as mapping for Parks Victoria's marine park inventory.

Limitations

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