One Tree Reef Geomorphological Evolution, Southern Great Barrier Reef

One Tree Reef evolved from a karst platform now 10 to 25 meters below sea level, which was emergent before 9600-9000 years B.P. The dataset describes the reef's asymmetrical triangular shape, 5.5 km long and 3 km wide, and its vertical and lateral accretion patterns influenced by sea-level rise and wave regimes over millennia. It is hosted by the Australian Ocean Data Network and was last updated in April 2026.

Use Cases

• Modeling reef growth and sediment accretion based on described vertical and lateral accretion processes.
• Analyzing the influence of wave refraction and diffraction on sediment patterns based on the symmetrical energy pattern described.
• Studying paleo-sea-level changes based on the karst platform depth and emergence timeline mentioned.
• Mapping coastal lagoon sedimentation dynamics based on described flood tide, swash transport, and slack water processes.

Strengths

• Includes specific physical dimensions: 5.5 km long and 3 km wide.
• Provides a detailed geological timeline, including emergence before 9600-9000 years B.P. and key growth phases by 4400 years B.P.
• Describes specific controlling processes for lagoonal sedimentation: flood tide, swash transport, and slack water.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to data_gov_au, focusing on a single reef.
