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 from six reefs in the Capricorn/Bunker group, measuring a seismic discontinuity at depths of 8-23 meters. Data was published by Geoscience Australia and last updated in March 2026.

Use Cases

• Modeling pre-Holocene surface topography based on seismic discontinuity depths.
• Assessing the relationship between substrate shape and modern reef growth forms.
• Investigating lagoon formation and infill history from seismic refraction profiles.
• Testing latitudinal genetic sequence hypotheses for reef development.

Strengths

• Includes 124 seismic refraction profiles from six specific reefs.
• Depth measurements for a key seismic discontinuity range from 8 to 23 meters.
• Data is tied to physical borehole evidence from three island locations.

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 Great Barrier Reef study area.
