Elizabeth and Middleton Reef Bathymetry Survey at 5m Resolution

Bathymetry data for Elizabeth and Middleton Reefs within the Lord Howe Marine Park was collected by Geoscience Australia from January 31 to February 6, 2020. The survey provides baseline seabed information using multibeam sonar, covering a combined area of 312 km² at a 5-meter grid resolution. This data supports the 10-year management plan (2018-2028) for the Temperate East Marine Park Network.

Use Cases

• Modeling seafloor topography based on high-resolution multibeam sonar data.
• Monitoring changes in benthic habitats over time based on baseline seabed mapping.
• Planning marine conservation zones based on detailed bathymetry and habitat data.

Strengths

• High-resolution 5-meter gridded bathymetry data.
• Covers a combined survey area of 312 square kilometers.
• Data collected using multiple methods including multibeam sonar, AUV imagery, sediment samples, and BRUV.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
