ALF-Compatible UV Fluorescence Spectra of 120 Offshore Western Australia Oils

Offshore Western Australia oils were analyzed for fluorescence signatures to aid hydrocarbon seep detection. The dataset contains ultraviolet fluorescence emission spectra for 120 oil samples, collected using excitation at 266 nm to match Airborne Laser Fluorosensor surveys. It was produced by AGSO's Petroleum and Marine Division as part of a multi-client remote sensing study.

Use Cases

• Correlating sea surface hydrocarbon anomalies detected by ALF surveys with known oil types based on fluorescence signatures.
• Typing hydrocarbon seeps to their geological sources using UV fluorescence emission spectra.
• Evaluating the type and quantity of aromatic hydrocarbons present in offshore oil samples.
• Comparing laboratory UVF spectra of known oils with airborne survey data for exploration targeting.

Strengths

• Contains spectra for 120 oil samples, representing all known offshore western Australian petroleum systems.
• Laboratory data is explicitly compatible with the Airborne Laser Fluorosensor (ALF) system operated by World Geoscience Corp. Ltd.
• Spectra are collected using a specific excitation wavelength of 266 nm, matching 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.
• Data may reflect geographic bias inherent to data_gov_au, focusing solely on Western Australian offshore oils.
