Research from Geoscience Australia and partners, published in the Journal of the Geological Society, London, describes the distribution of heat-producing elements in East Antarctica. The data includes heat production values from a 275 km transect along the Prydz Bay coastline, ranging from 0.02 to 66 µW per cubic meter. This information is intended to improve predictions of ice sheet behavior and sea-level change by refining heat flow assumptions in models.
Use Cases
- Refining heat flow assumptions in ice sheet models based on measured geothermal heat production data.
- Predicting ice surging and ice stream flow based on regional variations in sub-glacial heat flow.
- Mapping the distribution of heat-producing granites under the East Antarctic ice sheet using aeromagnetic data correlations.
Strengths
- Data is derived from geochemical analysis of rock samples along a specific 275 km transect.
- Provides quantified heat production values ranging from 0.02 to 66 µW per cubic meter.
- Research is linked to a peer-reviewed publication in the Journal of the Geological Society, London.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- The dataset's primary format is HTML, which may not be structured for direct analysis.
