The Bureau of Mineral Resources (BMR) research cruise 78 was conducted by the R/V Rig Seismic from March 24 to April 18, 1988. The cruise collected 1750 km of multichannel seismic data on the west Tasmanian margin and 265 km off southeast Tasmania, alongside geological sampling at 49 stations. The work aims to define basin geology, rifting history, stratigraphy, and petroleum potential.
Use Cases
- Model rifting history and basin evolution based on seismic survey data.
- Analyze petroleum potential based on stratigraphic and structural interpretations.
- Study Cainozoic sedimentation patterns based on core samples from 37 stations.
- Calculate thermal flux based on thermal gradient and conductivity measurements at 10 stations.
- Map the structure of the continental margin from shelf to oceanic crust based on seismic ties.
Strengths
- Seismic survey covers a specific 1750 km track on the west Tasmanian margin.
- Geological sampling includes 12 stations targeting basement and older sequences and 37 stations for younger sediments.
- Cruise duration and dates (March 24 to April 18, 1988) are explicitly documented.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data files are in PDF and HTML formats, which may require extraction or conversion for analysis.
