Holocene Sea-Level and Storm Data from the Great Barrier Reef Inner Zone

45 radiocarbon results from 11 sites on the Great Barrier Reef between 14° and 20° S, ranging between 360 and 5855 years B.P., are used to examine Holocene sea-level and climatic changes. The data, from the Australian Ocean Data Network, includes coral microatoll and storm-ridge surveys to reconstruct past environmental conditions. The dataset was last updated on 2026-04-10.

Use Cases

• Modeling historical sea-level trends based on coral microatoll age/height distributions.
• Analyzing storm frequency and intensity over millennia based on dated storm-ridge sequences.
• Calibrating isostatic adjustment models for sea-level reconstruction using the +1m datum at 5500 yr B.P.
• Investigating long-term climatic stability in reef systems based on the absence of identified frequency changes in storm events.

Strengths

• 45 radiocarbon dates provide a chronological framework for the analysis.
• Data spans 11 sites across a 6-degree latitudinal range (14° to 20° S) on the Great Barrier Reef.
• Sea-level trend confidence limits are reported as ±0.2 m.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Primary file formats are PDF and HTML, which may require extraction for computational analysis.
