Port Phillip Bay Bathymetry Survey for Sediment Movement Analysis, 2021

A 2021 bathymetric survey of Port Phillip Bay, Australia, conducted on December 13th by Deakin University's Marine Mapping lab. Data was collected from the Motor Vessel Yolla using a Kongsberg EM2040c sonar system to assess sediment movement over time. The dataset is provided by the Australian Ocean Data Network.

Use Cases

• Modeling coastal sediment transport based on bathymetric measurements.
• Analyzing seabed change over time using high-resolution sonar data.
• Supporting marine habitat mapping by inferring substrate types from bathymetry.

Strengths

• Data collected with a specific, high-resolution Kongsberg EM2040c sonar system.
• Survey conducted over a single day (13/12/2021), providing a temporal snapshot.
• Explicitly collected for the purpose of assessing sediment movement through time.

Limitations

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