Geoscience Australia's marine survey S282 collected sediment samples from the Arafura Sea. The dataset documents the detection and source assessment of organic contaminants introduced during sampling, including fatty acid amides, antioxidants, UV absorbers, and hydrocarbons. The primary aim of the survey was to detect evidence for natural hydrocarbon seepage.
Use Cases
- Identify contamination sources in geochemical samples based on detected organic compounds like fatty acid amides and butylated hydroxytoluene.
- Assess the risk of misinterpreting sampling artifacts as natural petroleum signals based on the presence of branched alkanes and alkyl cyclohexanes.
- Develop protocols for cleaner sample handling based on the analysis of contaminants from plastic bags, sunscreen, and shipboard materials.
Strengths
- Focuses on a specific, well-documented marine survey (S282) conducted by Geoscience Australia.
- Identifies specific contaminant compounds and their likely sources, such as plastic bags and sunscreen.
- Addresses a critical methodological issue in organic geochemistry by assessing contamination introduced during sampling.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Freshness should be verified as the last update date is 2026-05-14.
