Port Phillip Bay Bathymetry TieLines Survey from 2021

Deakin University Marine Mapping lab collected bathymetry data in Port Phillip Bay on December 13, 2021. The survey was conducted from the Motor Vessel Yolla using a Kongsberg EM2040c sonar system. These data were acquired to assess the movement of sediment through time.

Use Cases

• Modeling sediment transport patterns based on bathymetric survey data.
• Analyzing seabed elevation changes over time based on repeated survey data.
• Creating baseline maps for coastal management based on high-resolution sonar data.

Strengths

• Data was collected using a specific, high-resolution Kongsberg EM2040c sonar system.
• Survey date and collection platform (Motor Vessel Yolla) are explicitly documented.

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• Data may reflect geographic and temporal bias inherent to a single-day survey in 2021.
