Seismic and Geological Research Cruise Data from the Tasmanian Margin, 1988

March to April 1988 research cruise data collected by the R/V Rig Seismic for the Bureau of Mineral Resources. The dataset includes 1750 km of multichannel seismic lines on the west Tasmanian margin and 265 km off southeast Tasmania, plus geological sampling at 49 stations. The work was conducted to define basin geology, rifting history, stratigraphy, and petroleum potential.

Use Cases

• Model sedimentary basin structure based on multichannel seismic survey data
• Analyze the history of continental rifting based on seismic interpretation control samples
• Assess petroleum potential based on analysis of surface sediments for thermogenic gas
• Establish models for Cainozoic sedimentation based on core samples from 37 stations
• Calculate thermal flux based on near-surface thermal gradient and conductivity measurements

Strengths

• Includes 1750 km of multichannel seismic data on the west Tasmanian margin
• Geological sampling conducted at 49 stations, including 12 for basement control
• Thermal gradient and conductivity were measured at 10 stations
• Provides a key seismic tie through the thick sedimentary basin on the west Tasmanian slope

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 specific cruise in 1988; freshness should be verified for contemporary applications
