ALF Compatible UV Fluorescence Spectra of 120 Western Australian Oils

Western Australian offshore petroleum systems are represented by 120 oil samples analyzed for ultraviolet fluorescence emission spectra. The data were collected by AGSO's Petroleum and Marine Division to correlate airborne laser fluorosensor survey anomalies with known oil sources. This report concludes the first stage of a multi-client study on using fluorescence signatures for hydrocarbon seep detection and typing.

Use Cases

• Correlating sea surface hydrocarbon anomalies from ALF surveys with known oil types based on fluorescence signatures.
• Characterizing the aromatic hydrocarbon composition of oils from different offshore petroleum systems.
• Supporting geological and geochemical studies by providing a standalone spectral library of western Australian oils.

Strengths

• Contains fluorescence spectra for 120 distinct oil samples.
• Samples represent all known offshore western Australian petroleum systems as defined in referenced studies.
• Data collection method uses a specific excitation wavelength (266 nm) compatible with the operational ALF system.

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; last metadata update is 2026-05-14.
