The Australian Ocean Data Network hosts a dataset from a 1988 research cruise measuring light hydrocarbon gases (C1-C6) in sediments at 342 locations on the continental shelf and slope of the Otway and Gippsland Basins. Thermogenic hydrocarbons were identified in near-surface sediments at forty-two locations. The data includes results from specific platforms and troughs, with analyses of wet gas content and total gas concentrations.
Use Cases
- Identify thermogenic hydrocarbon sources based on sediment gas measurements at 342 locations
- Analyze hydrocarbon source type and maturity based on wet gas content ([C2-C4/C1-C4] x 100) data
- Model basin thermal maturation by integrating geochemical data with well data
- Compare gas concentration patterns between basin margins (Crayfish, Mussel Platforms) and troughs (Voluta Trough)
Strengths
- Data collection covers 342 specific sampling locations on the continental shelf and slope
- Results distinguish findings between the Otway Basin (17 days, 32 locations) and Gippsland Basin (4 days, 10 locations)
- Analysis includes specific sub-regions: Crayfish Platform, Mussel Platform, and Voluta Trough
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
