Organic contaminants detected in sediment samples from Geoscience Australia's marine survey S282 in the Arafura Sea include fatty acid amides, chemical antioxidants, and UV absorbers. The dataset likely contains results from solvent extraction analyses identifying contamination sources such as plastic sampling bags and sunscreen. The data was published by the Australian Ocean Data Network and last updated in April 2026.
Use Cases
- Identify contamination sources in marine sediment samples based on detected organic compounds.
- Assess the impact of sample handling and storage on geochemical data based on the described contamination pathways.
- Develop protocols for minimizing contamination in field sampling based on the identified sources like plastic bags and sunscreen.
- Interpret hydrocarbon signals in sediments by distinguishing anthropogenic contaminants from natural seepage evidence.
Strengths
- Focuses on a specific and documented contamination issue in marine geochemistry.
- Identifies concrete contamination sources such as two brands of plastic bags and sunscreen.
- Based on a real marine survey (S282) conducted by Geoscience Australia.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Description metadata is limited; actual data quality requires manual inspection after download.
