130 sampling stations were occupied during a 29-day research cruise in early 1987 aboard R.V. Rig Seismic. Scientists from the Australian Ocean Data Network collected geological, geochemical, and heatflow data over the Otway and Sorell Basins. Heatflow calculations from 20 stations suggest the zone of thermal maturation for hydrocarbons is 2-4 km deep.
Use Cases
- Model hydrocarbon maturation zones based on heatflow data from 20 stations.
- Develop regional sedimentation models based on a variety of Quaternary sediments recovered.
- Analyze the distribution of thermogenic hydrocarbons based on headspace gas analyses of cores.
- Correlate rock age with continental slope depth based on samples taken along seismic profiles.
- Assess post-Eocene subsidence of the slope based on palaeontological results.
Strengths
- 130 sampling stations provide a spatially distributed dataset.
- Heatflow calculations from 20 stations offer specific subsurface thermal data.
- All samples were taken along seismic profiles, enabling integration with regional geological frameworks.
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 and temporal bias inherent to a single 1987 cruise.
