One Tree Reef Geomorphic Evolution and Sediment Patterns

One Tree Reef in the southern Great Barrier Reef evolved from a karst platform now 10 to 25 meters below sea level. The dataset details its 5.5 km by 3 km asymmetrical shape and sediment patterns influenced by a wave regime established around 4400 years B.P. It is provided by the Australian Ocean Data Network and was last updated in April 2026.

Use Cases

• Modeling reef growth from karst platform depth (10-25m below sea level) against sea-level rise timelines.
• Analyzing the relationship between present wind-induced southeasterly wave regime and symmetrical sediment patterns about the lagoonal axis.
• Studying the control of flood tide, swash transport, and slack water periods on present lagoonal sedimentation dynamics.
• Reconstructing paleo-shorelines using the reef's emergent period before 9600-9000 years B.P. and vertical accretion history.

Strengths

• Detailed geomorphic and evolutionary history covering a key period from before 9600-9000 years B.P. to present.
• Specific spatial dimensions provided for the reef (5.5 km long, 3 km wide).
• Clear temporal markers for major evolutionary phases (e.g., 4400 years B.P.).

Limitations

• No structured data rows or columns are explicitly defined; information is contained in descriptive text (PDF/HTML).
• Sample size and quantitative measurements for sediment or growth rates are not specified.
• Geographic scope is limited to a single reef within the Capricorn Group.
