ALF Compatible UV Fluorescence Spectra of 120 Offshore Western Australia Oils

120 ultraviolet fluorescence emission spectra of oil samples from offshore Western Australia. The data were collected by the Australian Geological Survey Organisation's Petroleum and Marine Division to correlate with airborne laser fluorosensor surveys. This report concludes the first stage of a multi-client 'remote sensing' study and is designed as a standalone product.

Use Cases

• Correlating sea-surface hydrocarbon anomalies detected by Airborne Laser Fluorosensor (ALF) surveys with known oil samples based on fluorescence signatures.
• Typing hydrocarbon seeps to their geological sources based on the aromatic hydrocarbon profiles revealed by UV fluorescence.
• Comparing the fluorescence spectra of known oils from all offshore Western Australian petroleum systems with new survey data.

Strengths

• Contains spectra for 120 distinct oil samples, providing a substantial reference set.
• Samples represent all known offshore Western Australian petroleum systems, offering comprehensive regional coverage.
• Laboratory method uses an excitation wavelength of 266 nm, matching the operational ALF system for direct compatibility.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
