One Tree Reef Geomorphology and Sedimentation Patterns, Southern Great Barrier Reef

One Tree Reef, a 5.5 km by 3 km asymmetrical triangular reef in the Capricorn Group, evolved from a karst platform 10-25m below sea level. The dataset describes its formation from before 9600-9000 years B.P., with vertical and lateral accretion leading to its present shape influenced by a southeasterly wave regime by 4400 years B.P. It is sourced from the Australian Ocean Data Network via data.gov.au and was last updated on 2026-04-10.

Use Cases

• Modeling reef geomorphological evolution based on described karst platform origin and accretion history.
• Analyzing sediment transport patterns based on described wave refraction, diffraction, and symmetrical energy patterns.
• Studying paleoenvironmental sea-level changes based on the timeline from emergent low stand to present conditions.
• Mapping present lagoonal sedimentation controls based on described flood tide, swash transport, and slack water deposition.

Strengths

• Provides specific physical dimensions (5.5 km long, 3 km wide) and depth range (10-25m below sea level).
• Includes a detailed evolutionary timeline with key dates (before 9600-9000 years B.P., by 4400 years B.P.).
• Describes present-day controlling processes (wave regime, sediment transport mechanisms) with concrete detail.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is presented in PDF/HTML formats, which may require extraction for computational analysis.
