Seismic Refraction Profiles for Coral Reef Substrate Analysis on the Great Barrier Reef

Seismic refraction studies conducted near boreholes at Bewick, Hayman, and Heron Islands on the Great Barrier Reef. The dataset includes 124 profiles completed on six reefs within the Capricorn/Bunker Reefs group, correlating seismic discontinuities with geological unconformities. Data was published by Geoscience Australia Data and last updated in April 2026.

Use Cases

• Correlating seismic discontinuity depths with Holocene/pre-Holocene unconformities based on borehole data mentioned in the description
• Assessing the influence of pre-Holocene substrate topography on modern reef growth forms as described
• Mapping the central depression and raised rim structure of pre-Holocene surfaces beneath reef lagoons
• Testing hypotheses about latitudinal genetic sequences for reefs in the southern Great Barrier Reef

Strengths

• Includes 124 seismic refraction profiles across six reefs, providing substantial spatial coverage
• Data is directly correlated with physical borehole samples from three specific islands
• Identifies a marked seismic discontinuity at depths ranging from 8 to 23 meters

Limitations

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