A laboratory study conducted to determine effective methods for detecting C10 to C40 hydrocarbons in marine sediments at naturally occurring oil seeps. The results indicate a commercially available method using hexane extraction and gas chromatography is effective for concentrations between 50 to 5,000 ppm. The dataset is provided by the Australian Ocean Data Network and was last updated on 2026-06-23.
Use Cases
- Validate gas chromatography methods for hydrocarbon detection based on the described 50-5,000 ppm concentration range.
- Compare detection techniques for biodegraded vs. unbiodegraded oil charges based on the described use of n-alkanes and Unresolved Complex Mixture (UCM).
- Screen for low-concentration petroleum hydrocarbons below 50 ppm based on the described effectiveness of GC-MS.
- Assess hydrocarbon migration at natural oil seeps based on the described laboratory study focus.
Strengths
- Describes specific concentration ranges for method effectiveness (50 to 5,000 ppm).
- Compares analytical techniques for different oil conditions (unbiodegraded vs. biodegraded).
- Identifies a specific lower detection limit for GC-MS (below 50 ppm).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
