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

One Tree Reef in the Capricorn Group is 5.5 km long and 3 km wide, with a coral cay on its southeastern corner. The dataset describes its evolution from a karst platform emergent before 9600-9000 years B.P., through vertical and lateral accretion, to its present shape influenced by wave regimes since 4400 years B.P. It details the present symmetrical sediment pattern controlled by wave surge transport and slack water deposition.

Use Cases

• Model reef geomorphological evolution based on described accretion processes and sea-level history.
• Analyze sediment transport patterns based on the described wave regime and lagoonal axis.
• Study the impact of sea-level change on reef structure based on the described emergence and submergence timeline.

Strengths

• Provides specific dimensions (5.5 km long, 3 km wide) and depth range (10 to 25m below sea level).
• Includes precise historical timeframes (9600-9000 years B.P. and 4400 years B.P.) for key evolutionary stages.
• Describes a clear physical model of wave energy influence and sediment sorting mechanisms.

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.
