One Tree Reef Evolution and Sediment Patterns, Southern Great Barrier Reef

One Tree Reef is one of fourteen reefs in the Capricorn Group, southern Great Barrier Reef, with an asymmetrical triangular shape 5.5 km long and 3 km wide. The dataset, provided by the Australian Ocean Data Network, describes its evolution from a karst platform 10-25m below sea level, emergent before 9600-9000 years B.P., and its growth into the present wave regime by 4400 years B.P. Present sediment patterns are influenced by a symmetrical wave energy pattern around a lagoonal axis.

Use Cases

• Modeling reef geomorphological evolution based on described karst platform origins and accretion history.
• Analyzing sediment transport patterns based on described flood tide, swash, and slack water controls.
• Studying the impact of sea-level change on coral reef structure based on the described emergence and submergence timeline.
• Mapping wave energy refraction and diffraction effects on reef shape based on the described 'bow of a ship' analogy.

Strengths

• Description provides specific physical dimensions: 5.5 km long and 3 km wide.
• Includes concrete temporal markers for geological events, such as emergence before 9600-9000 years B.P. and growth by 4400 years B.P.
• Describes a specific geological process: evolution from a karst carbonate platform now 10 to 25m below sea level.

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.
