U-Series Coral Age Data from Pelorus Island, Great Barrier Reef

U-series dating data from coral death assemblages at three reef sites on Pelorus Island, collected via SCUBA surveys. The dataset includes uranium and thorium concentrations and corrected ages, supporting research on historical coral collapse following European settlement. Data originates from the Roff et al (2013) study and is hosted by the Australian Ocean Data Network.

Use Cases

• Reconstructing historical coral mortality timelines based on corrected 230Th ages.
• Analyzing geochemical signatures in reef skeletons using uranium and thorium concentration data.
• Investigating the impact of European settlement on inshore reef ecosystems using dated coral assemblages.

Strengths

• Data is derived from a published study in the Proceedings of the Royal Society Series B.
• Sample collection followed a structured method using belt transects and random sampling points.
• Age data includes both uncorrected and corrected 230Th ages for analysis.

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 the three specific sites at Pelorus Island.
