Three sediment cores from Nara Inlet in the Whitsunday Islands, central Great Barrier Reef, Australia, were collected by the Australian Ocean Data Network. The cores contain data on sediment composition and accumulation rates over the last 3000 years, with the top 3 meters of sediment analyzed. The dataset was last updated on 2026-04-16.
Use Cases
- Modeling sediment accumulation rates over the last 3000 years based on radiocarbon dating mentioned in the description.
- Analyzing the temporal shift from clastic to carbonate-dominated sediment based on component percentages.
- Investigating the impact of fringing reef growth on terrigenous sediment input as described.
- Studying the provenance and redistribution of middle-shelf terrigenous material during sea-level changes.
Strengths
- Data covers a 3000-year temporal record from the Late Holocene.
- Sediment composition is quantified, with a specific carbonate component of 25.80% by weight reported.
- Cores provide spatial context from three locations within a defined natural depocenter (Nara Inlet).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to data_gov_au, focusing on a single inlet.
