A 1988 research cruise conducted seismic surveys and geological sampling off Tasmania. The R/V Rig Seismic collected 1750 km of multichannel seismic data on the west Tasmanian margin and 265 km off southeast Tasmania, followed by geological sampling at 49 stations. The work was carried out by the Bureau of Mineral Resources (BMR) to define basin geology, rifting history, and petroleum potential.
Use Cases
- Analyze basin structure and rifting history based on multichannel seismic survey data
- Model Cainozoic sedimentation patterns based on core samples from 37 stations
- Define areas of anomalous thermogenic gas concentrations based on surface sediment analysis
- Establish thermal flux models based on near-surface thermal gradient and conductivity measurements at 10 stations
Strengths
- 1750 km of multichannel seismic data collected on the west Tasmanian margin
- 265 km of seismic data collected off southeast Tasmania
- Geological sampling conducted at 49 stations, including 12 targeting basement and older sequences
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 temporal bias inherent to a single 1988 cruise
