In early 1987, scientists aboard R.V. Rig Seismic conducted a 29-day research cruise over the Otway Basin and Sorell Basin of the west Tasmanian margin. The Australian Ocean Data Network provides data from 130 sampling stations using dredges, corers, grabs, and a heatflow probe. The cruise aimed to provide new geological, geochemical, and heatflow data in an area with considerable petroleum potential.
Use Cases
- Model hydrocarbon thermal maturation based on heatflow calculations from 20 stations
- Develop regional sedimentation models based on a variety of Quaternary sediments recovered
- Map the distribution of thermogenic hydrocarbons based on headspace gas analyses of cores
- Correlate rock age with depth down the continental slope based on samples taken along seismic profiles
Strengths
- 130 sampling stations provide a substantial spatial coverage
- Heatflow calculations from 20 stations suggest a zone of thermal maturation 2-4 km deep
- All samples were taken along seismic profiles for easy incorporation into regional frameworks
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
