Port Phillip Bay Bathymetry Survey for Sediment Movement, 2021

Port Phillip Bay bathymetry tielines survey was acquired by Deakin University Marine Mapping lab on December 13, 2021. Data were collected from the Motor Vessel Yolla using a Kongsberg EM2040c to assess sediment movement through time. The dataset is provided by Geoscience Australia Data.

Use Cases

• Modeling sediment transport pathways based on high-resolution seabed elevation data.
• Analyzing bathymetric change over time for coastal management.
• Calibrating hydrodynamic models with precise seafloor topography.

Strengths

• Data collection uses a specific, high-resolution multibeam echosounder (Kongsberg EM2040c).
• Survey has a precise acquisition date (December 13, 2021).
• Data purpose is clearly stated: to assess sediment movement.

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.
