Ashmore Reef Sediment and Coral Data from 12 Vibro-Cores

12 vibro-cores from Ashmore Reef provide data on sediment facies and coral growth phases over the past 11,000 years. The dataset, sourced from Geoscience Australia Data, includes carbon dates ranging from 970 to 2020 BP, indicating a major bio-facies change around 2000 BP. It models reef development based on sea level curves and facies changes extrapolated from the One Tree Reef model.

Use Cases

• Modeling coral reef development phases based on post-glacial sea level curves mentioned in the description
• Analyzing sediment infill rates based on the described 0.73 cm/yr lagoon accumulation
• Studying bio-facies transitions from coral to algal dominance based on carbon-dated sediment changes
• Mapping biogenic sand sheet mobility and bioturbation patterns across the reef platform

Strengths

• Includes carbon-14 dated facies changes with dates ranging from 970 to 2020 BP
• Based on a series of 12 vibro-cores providing physical samples
• Derived from a model incorporating an 11,000-year relative sea level curve

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data is presented in HTML format, which may require extraction for analysis
