Biogeography of the Lord Howe Rise Marine Region

Biogeography of the Lord Howe Rise region synthesizes physical and biological information across a 1.95 million km² area of the Tasman Sea. The dataset describes differences in biological assemblages and species distribution between raised and subdued bathymetric features, influenced by substrate and depth. It integrates data from two marine surveys, TAN0713 and NORFANZ, to assess regional patterns at a scale of hundreds of kilometres.

Use Cases

• [Analyzing species distribution patterns] based on [differences between raised and subdued bathymetric features]
• [Modeling habitat suitability] based on [physical factors like depth and substrate]
• [Assessing regional biogeography] based on [synthesized physical and biological information across 1.95 million km²]
• [Studying latitudinal gradients] based on [data for demersal fish and other taxa across 18.4°S to 40.3°S]

Strengths

• Covers a large, defined geographic area of 1.95 million km²
• Integrates biological data from two named scientific surveys, TAN0713 and NORFANZ
• Explicitly analyzes relationships between biological communities and geomorphic feature types

Limitations

• No column names or specific data structure are provided, limiting technical assessment
• The description indicates limited spatially-replicated studies and no time-series data for most of the region
• Metadata for size, rows, license, and author is consistently listed as unknown or None across all platform entries
