61 drill holes into 24 reefs across the Great Barrier Reef Province between 15°30S and 25°50S provide nearly 250 radiocarbon dates. Scientists from the Bureau of Mineral Resources and James Cook University analyzed core samples to delineate five major biosedimentologic facies and measure depositional rates over the past 8-9000 years.
Use Cases
- Model reef growth rates based on measured rates ranging from 1-16 m/1000yr.
- Analyze latitudinal uniformity in framework facies versus regional variations in detrital facies.
- Study the relationship between sea-level rise and reef initiation lag described in the data.
- Compare depositional rates for different facies, such as detrital carbonate facies varying between 1-18 m/1000 yr.
- Investigate the depth to the Pleistocene and reef initiation timing across the northern, central, and southern regions.
Strengths
- 61 drill holes provide a substantial sample across 24 reefs.
- Nearly 250 radiocarbon dates offer a detailed chronological framework.
- Analysis delineates five distinct biosedimentologic facies with quantified growth rates.
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 to structured formats for analysis.
