Port Phillip Bay Bathymetry Survey for Sediment Movement Analysis

Bathymetric survey data from Port Phillip Bay, Australia, collected by Deakin University Marine Mapping lab on December 13, 2021. The data was acquired over one day using a Kongsberg EM2040c multibeam echosounder onboard the Motor Vessel Yolla. The primary purpose was to assess the movement of sediment through time.

Use Cases

• Model sediment transport pathways based on high-resolution seabed elevation data.
• Analyze changes in seabed morphology over time by comparing with historical surveys.
• Support coastal management decisions based on sediment movement assessments.

Strengths

• Data collected using a Kongsberg EM2040c multibeam echosounder, a high-precision instrument.
• Survey conducted over a single day (13/12/2021), providing a consistent temporal snapshot.

Limitations

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