Biogeography of the Lord Howe Rise Region in the Tasman Sea

The Lord Howe Rise region in the Tasman Sea covers 1.95 million km² and spans tropical to cool temperate latitudes from 18.4°S to 40.3°S. This review synthesizes physical and biological information, describing differences in species assemblages between raised seamounts and subdued sediment plateaus. It was published by the Australian Ocean Data Network and last updated in 2026.

Use Cases

• Modeling species distribution based on latitudinal gradients mentioned for demersal fish.
• Analyzing biological community differences between raised seamounts and subdued sediment basins described in the review.
• Assessing the influence of substrate and depth-related variables on marine assemblages as suggested by survey data.
• Studying paleo-environmental processes related to migration, speciation, and endemism in the region.

Strengths

• Covers a large geographic area of 1.95 million km².
• Synthesizes data from at least two named scientific surveys (TAN0713 and NORFANZ).
• Explicitly describes the region's topographic complexity, including seamounts, guyots, knolls, and pinnacles.

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.
• The review notes only limited spatially-replicated studies and no time-series data are available for most of the region.
