Portsea Hole Bathymetry Survey in Port Phillip Bay, 2018

Portsea Hole bathymetry survey was acquired by Deakin University Marine Mapping lab onboard the Motor Vessel Yolla over two days in 2018 (20/01/2018-21/01/2018) using a Kongsberg EM2040c. This survey was collected as part of a Parks Victoria project to map all the marine parks within Victorian state waters. The data is provided by Geoscience Australia.

Use Cases

• Modeling seabed topography based on the bathymetry survey data.
• Analyzing marine park habitats using the detailed seafloor mapping.
• Studying coastal erosion or sediment transport patterns in Port Phillip Bay.
• Validating or supplementing broader regional hydrographic charts.

Strengths

• Survey conducted with a specific high-resolution multibeam echosounder (Kongsberg EM2040c).
• Data collection occurred over two consecutive days, providing a focused temporal snapshot.
• Survey was part of a structured project by Parks Victoria to map marine parks.

Limitations

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