A 6,000-year record from 11 inner-shelf sites on the Great Barrier Reef examines Holocene environmental changes. The dataset includes 45 radiocarbon dates from coral microatolls and storm ridge sequences, used to reconstruct sea-level trends and storm recurrence intervals. It was published by Geoscience Australia and last updated in May 2026.
Use Cases
- Reconstructing Holocene sea-level curves based on dated coral microatolls.
- Analyzing storm frequency and intensity over millennia based on dated storm-ridge sequences.
- Modeling isostatic adjustments and coastal response to sea-level change based on the described spatial and temporal data.
Strengths
- Contains 45 radiocarbon results providing a quantitative chronological framework.
- Sea-level trend has defined confidence limits of ±0.2 meters.
- Data spans a long temporal range from 360 to 5,855 years before present.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data files are in PDF and HTML formats, which may require extraction for quantitative analysis.
