Ashmore Reef Sediment and Coral Data from Vibro-Cores and Carbon Dating

Geoscience Australia Data provides a dataset on Ashmore Reef's sedimentological response to Holocene sea-level rise. The model is derived from a post-glacial sea-level curve, C14 dated facies changes, and growth phases extrapolated from a reference reef model. Data collection involved 12 vibro-cores across algal-foraminiferal sand and coral, with carbon dates ranging from 970 to 2020 BP.

Use Cases

• Modeling reef growth phases based on the extrapolated One Tree Reef model mentioned in the description.
• Analyzing bio-facies changes from coral columns to algal-dominated flats using carbon-dated sediment facies.
• Studying sediment infill rates based on the described composition of Halimeda, coral fragments, and foraminifera.
• Investigating the impact of sea-level stabilization on reef crest morphology around ~2000 BP.

Strengths

• Includes carbon-dated sediment facies with dates ranging from 970 to 2020 BP.
• Based on a series of 12 vibro-cores through specific sediment and coral types.
• Derived from a post-glacial relative sea-level curve covering the past 11,000 years.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
