Lord Howe Rise Benthic Environments from 2003 and 2007 Marine Surveys

1.6 million km² of submarine plateaus exist within the Australian exclusive economic zone, representing about 13.8% of the world's known inventory. The Australian Ocean Data Network presents results from two major marine surveys on the Lord Howe Rise plateau in 2003 and 2007, collecting biological samples, underwater photos, video, and sonar bathymetry data.

Use Cases

• Map benthic habitat distribution based on collected underwater photographs and video
• Analyze epifaunal assemblages dominated by suspension feeders on hard/rocky substrates
• Assess ecological significance of volcanic peaks and seamounts using CBD scientific criteria
• Study geological features of the Lord Howe Rise plateau using multibeam sonar bathymetry data

Strengths

• Data originates from two major marine surveys conducted in 2003 and 2007
• Covers a specific area of volcanic peaks around 31 km² and parts of larger seamounts
• Includes multiple data modalities: biological/geological samples, photographs, video, and sonar bathymetry

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Freshness should be verified; last metadata update is 2026-06-17 00:23:31.416742
