Lord Howe Rise Biogeography: Physical and Biological Data Synthesis

A synthesis of physical and biological information for the Lord Howe Rise region in the Tasman Sea. The dataset covers an area of 1.95 million km2, spanning tropical to cool temperate latitudes from 18.4°S to 40.3°S. It was published by the Australian Ocean Data Network and last updated in April 2026.

Use Cases

• Modeling species assemblage differences between raised and subdued bathymetric features based on described biological data.
• Analyzing latitudinal gradients in demersal fish distribution across the 18.4°S to 40.3°S range.
• Assessing the influence of substrate and depth-related variables on biological communities as suggested by survey findings.
• Studying regional-scale biogeography and endemism patterns in a topographically complex marine region.

Strengths

• Covers a large geographic area of 1.95 million km2.
• Integrates data from at least two named scientific surveys (TAN0713 and NORFANZ).
• Explicitly describes analysis of differences between raised and subdued bathymetric features.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The description notes limited spatially-replicated studies and no time-series data for most of the region.
