Coral Size Patterns Across Environmental Gradients on the Great Barrier Reef

5880 coral colonies were measured from large-area orthomosaics across 84 sites on the Great Barrier Reef and Torres Strait. The dataset, associated with the EcoRRAP sub-program, tests hypotheses about coral size structure across gradients in latitude, cross-shelf position, wave exposure, and depth. It was last updated on 2026-07-16.

Use Cases

• Modeling coral population recovery potential based on colony size and environmental gradients.
• Identifying source reefs for larval replenishment based on the prevalence of larger colonies.
• Analyzing the vulnerability of different coral morphotaxa to environmental forcing like wave exposure.

Strengths

• Includes measurements for 5880 coral colonies, providing a substantial sample size.
• Covers 84 sites across a broad geographic range from the Torres Strait to the southern Great Barrier Reef.
• Data collection used photogrammetry imaging procedures, likely providing high-resolution spatial data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
