Lord Howe Island Shelf Bathymetry and Habitats Flythrough Video

A flythrough movie visualizes the bathymetry of the shelf surrounding Lord Howe Island, New South Wales. The bathymetric image is derived from merged grids at 8 m and 40 m resolution, incorporating multibeam sonar data collected in 2008, legacy sonar data, and satellite-derived bathymetry. The dataset was produced as part of the Marine Biodiversity Research Hub, funded by the Commonwealth Environment Research Facilities programme.

Use Cases

• Visualizing seabed topography based on the bathymetric flythrough movie
• Studying drowned reef structures based on the key features described
• Analyzing sediment-covered basins based on the shelf bathymetry description
• Mapping seabed habitats based on the examples of biota and habitats shown

Strengths

• Bathymetry derived from merged grids at 8 m and 40 m resolution
• Incorporates multibeam sonar data from a 2008 survey using a 30 kHz Simrad EM300 system
• Integrates legacy sonar data and satellite-derived bathymetry
• Detailed documentation referenced in GA Records 2010/36 and 2010/26

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download
• Column-level documentation is absent; field semantics must be inferred after download
• Data may reflect geographic/temporal/source bias inherent to data_gov_au
