Late Holocene Sediment Core Data From Nara Inlet

Three sediment cores from Nara Inlet in Australia's central Great Barrier Reef document sediment accumulation over the last 3000 years. The Australian Ocean Data Network published this analysis of clastic and carbonate sediment composition and accumulation rates. The data originates from a scientific journal paper last updated in 2026.

Use Cases

• Analyze the relationship between sediment depth and radiocarbon age using the top 3 meters of core data spanning 3000 years.
• Model changes in clastic versus carbonate accumulation rates over time using weight percentage data, such as the 25.80% carbonate component.
• Study the composition of marine carbonate sediment by examining features like Sr-poor foraminifera tests and mollusc shells.
• Investigate the impact of fringing reef growth on terrigenous sediment impedance as inferred from core stratigraphy.

Strengths

• Three distinct sediment cores provide a multi-point spatial sample.
• Temporal coverage spans approximately 3000 years of late Holocene history.
• Quantitative data includes specific metrics like carbonate weight percentage (25.80%).

Limitations

• Small sample size of only three cores limits broad statistical analysis.
• Specific row counts, column names, and full data tables are not provided in the description.
• The primary data format is an HTML journal paper, not a structured dataset.
