Hydrocarbon Sniffer Survey Data from Southeastern Australia, 1989

Light hydrocarbon gas measurements from a 30-day research cruise in southeastern Australian offshore basins conducted between February 1 and March 2, 1989. The survey was a cooperative project between the Australian Bureau of Mineral Resources and Transglobal Exploration and Geoscience. Data likely includes concentrations and molecular compositions of gases from the water column and sediments to assess petroleum potential.

Use Cases

• Mapping hydrocarbon seepage anomalies based on water column gas concentrations mentioned in the description
• Correlating gas compositions with underlying basin geology and known oil/gas fields as described
• Evaluating the 'sniffer' survey technique's applicability for Australian offshore exploration contexts

Strengths

• Specific 30-day survey duration from February 1 to March 2, 1989
• Covers multiple defined geological basins: Gippsland, Bass, Otway, Stansbury Basins and Torquay Sub-basin
• Includes both regional survey lines and detailed proprietary programs over known accumulations

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 geographic/temporal bias inherent to data_gov_au
