UV Fluorescence Spectra of 120 Offshore Western Australian Oils

120 oil samples from offshore Western Australia were analyzed using ultraviolet fluorescence spectroscopy with 266 nm excitation. The dataset provides emission spectra from 280-500 nm to evaluate aromatic hydrocarbon types and quantities, designed for correlation with airborne laser fluorosensor survey data. It represents all known offshore petroleum systems in the region as defined by published studies.

Use Cases

• Correlate airborne laser fluorosensor (ALF) survey anomalies with known oil UVF emission spectra from 280-500 nm.
• Characterize hydrocarbon seeps by typing them to source oils using fluorescence signatures.
• Evaluate the type and quantity of aromatic hydrocarbons present in 120 diluted oil samples.
• Compare laboratory UVF spectra of known oils with remote sensing data for petroleum system analysis.

Strengths

• Contains 120 oil samples representing all known offshore Western Australian petroleum systems.
• Spectra are compatible with the specific 266 nm excitation wavelength used by operational ALF systems.
• Data is integrated with supplementary geological and geochemical information from 'The Oils of Western Australia' study.

Limitations

• Sample data and specific columnar structure are unavailable for direct machine learning ingestion.
• Primary data is delivered in report formats (HTML, ZIP), requiring extraction and structuring for analysis.
• Temporal coverage and sample collection dates are not specified, potentially limiting recency assessments.
