Twenty new heat-flow values from sites across Australia are presented, combined with published land and marine data. The data produce contour maps showing heat flux between 30-100 mW m^-2 across the region 90-170°E, 0-45°S. The Australian Ocean Data Network published this dataset.
Use Cases
- Mapping regional geothermal gradients based on heat flux measurements
- Correlating heat flow with seismic anomalies based on P-wave travel-time residuals
- Investigating crustal age and structure based on low heat-flow values in old crustal regions
- Delineating boundaries of Precambrian cratons based on heat-flow regime patterns
Strengths
- Includes 20 new heat-flow measurements from widely separated sites
- Combines new data with published land and marine data for a broader regional analysis
- Provides specific heat flux ranges (30-60 mW m^-2 for low, 70-100 mW m^-2 for high) for different regions
Limitations
- Data distribution is described as 'not good enough' to accurately delineate boundaries of heat-flow regimes
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
