Lord Howe Island Shelf Bathymetry and Habitat Flythrough Video

Geoscience Australia provides a flythrough video showing the bathymetry and seabed habitats of the Lord Howe Island shelf. The bathymetric image is derived from merged grids at 8 m and 40 m resolution, incorporating multibeam sonar data from 2008, legacy sonar, and satellite-derived bathymetry. This dataset was produced as part of the Marine Biodiversity Research Hub under the Commonwealth Environment Research Facilities programme.

Use Cases

• Visualizing seabed geomorphology based on the described drowned reef and sediment basins.
• Analyzing habitat distribution based on the video's depiction of seabed biota.
• Teaching or presenting marine shelf environments based on the flythrough movie format.

Strengths

• Bathymetric data derived from merged grids at 8 m and 40 m resolution.
• Incorporates multibeam sonar data from a 2008 survey using a Simrad EM300 system.
• Includes legacy sonar data and satellite-derived bathymetry for comprehensive coverage.

Limitations

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