Seismic and Geological Survey Data from the Tasmanian Margin, 1988

R/V Rig Seismic conducted Bureau of Mineral Resources research cruise 78 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 by the Australian Ocean Data Network aims to define basin geology, rifting history, stratigraphy, and petroleum potential.

Use Cases

• Model basin structure and rifting history based on multichannel seismic survey data.
• Analyze petroleum potential based on seismic ties through thick sedimentary basins and known oil seeps.
• Establish models for Cainozoic sedimentation based on core samples from 37 stations.
• Define areas of anomalous thermogenic gas concentrations based on surface sediment analysis.
• Calculate thermal flux based on near-surface thermal gradient and conductivity measurements from 10 stations.

Strengths

• Multichannel seismic survey covers 1750 km on the west Tasmanian margin and 265 km off southeast Tasmania.
• Geological sampling includes 12 stations for basement/older sequences and 37 stations for coring younger sequences.
• Thermal gradient and conductivity were measured at 10 stations to establish thermal flux.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is from a single cruise in 1988; temporal coverage is limited.
