124 seismic refraction profiles were completed on six reefs in the Capricorn/Bunker Reefs area. The dataset, from Geoscience Australia Data, contains results from studies near boreholes at Bewick, Hayman, and Heron Islands. It shows a seismic discontinuity at depths of 8-23 meters, equated with the Holocene/pre-Holocene unconformity.
Use Cases
- Modeling the pre-Holocene surface topography based on seismic discontinuity depths
- Assessing the influence of substrate shape on modern reef growth forms
- Correlating geophysical data with borehole stratigraphy from the Great Barrier Reef
- Investigating the infill history of reef lagoons through Holocene sedimentation patterns
Strengths
- 124 seismic refraction profiles provide a substantial geophysical survey
- Data correlates with physical borehole samples from three specific island locations
- Identifies a clear 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 analysis
