R/V Rig Seismic Geophysical and Geological Data from the Tasmanian Margin, 1988

1750 km of multichannel seismic data were collected on the west Tasmanian margin and 265 km off southeast Tasmania during a 1988 research cruise. The Bureau of Mineral Resources (BMR) conducted the cruise from March 24 to April 18, 1988, to examine basin structure and petroleum potential. Geological samples were taken at 49 stations, and thermal measurements were made at 10 stations to support seismic interpretation and sedimentation modeling.

Use Cases

• Model basin rifting history based on multichannel seismic survey lines.
• Analyze petroleum potential based on described examination of sedimentary basins and known oil seeps.
• Study Cainozoic sedimentation patterns based on core samples from 37 stations.
• Map thermal flux and subsurface temperature gradients based on measurements from 10 stations.
• Interpret seismic data with geological control based on basement and sequence samples from 12 stations.

Strengths

• Contains 1750 km and 265 km of multichannel seismic survey lines providing spatial coverage.
• Includes geological samples from 49 stations and thermal measurements from 10 stations for ground truthing.
• Focuses on specific geological targets: the King Island and Strahan Sub-basins and sequences near Bruny Island.

Limitations

• Data is from a single cruise in 1988; temporal coverage is limited.
• Row count and column-level documentation are unknown, limiting suitability assessment.
• File formats are PDF and HTML, which may require extraction or conversion for computational analysis.
