One Tree Reef Geomorphological Evolution, Southern Great Barrier Reef

One Tree Reef evolved from a karst platform emergent before 9600-9000 years B.P., with vertical organic accretion dominant during sea-level rise. By 4400 years B.P., the reef grew into the present wave regime, influencing its current asymmetrical triangular shape and symmetrical sediment pattern. The dataset, from Geoscience Australia Data, describes the reef's formation and present lagoonal sedimentation controlled by tidal and wave processes.

Use Cases

• Modeling coral reef geomorphological evolution based on described accretion patterns and sea-level history
• Analyzing sediment transport and deposition patterns based on described wave refraction and tidal controls
• Studying the impact of paleo-sea-level changes on reef structure based on the described emergence and submergence timeline
• Mapping present reef shape and energy patterns based on the described asymmetrical triangular form and wave regime

Strengths

• Provides a detailed geological timeline, including specific dates like 9600-9000 years B.P. and 4400 years B.P.
• Includes precise physical dimensions of the reef: 5.5 km long and 3 km wide with an asymmetrical triangular shape
• Describes specific controlling processes for present sedimentation: flood tide, swash transport, and slack water periods

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
