Cowley, R., 2001. Mk II Airborne Laser Fluorosensor Survey Reprocessing and Interpretation Report: Great Australian Bight, Southern Australia. Record  2001/018. AGSO-Geoscience Australia, Canberra.

Abstract

The Great Australian Bight airborne laser fluorosensor (ALF) MkII survey was flown in 1989 by BP. The MkII system used a 308nm laser wavelength, longer than the 266nm used in the later MkIII system. The Raman peak wavelength is 344nm and the fluorescence region is 370nm to 580nm. This report is a reinterpretation of the original BP data using ALF_Explorer software. Survey lines were numbered from 1 to 281 but many lines had several segments. A total of 520 line segments were detected in this survey using a line break distance of 100m. Lines 201 and 203 had 92 and 71 segments respectively. A noisy navigation system may have produced apparent breaks on these lines. If the extra segments on these lines are excluded, the survey contains 359 segments. The lines were acquired at approximately 3,000m spacing in a NS orientation and a flying height of 100m. A total of 33,154,869 spectra were processed at an average spacing of 15m to 22m. Each recorded spectrum is the average of ten detected spectra. The averaging was done to reduce the data recording rate, which was limited by the available hardware. The fluorescence response was very weak for the Great Australian Bight ALF survey, requiring a very sensitive detection method. The 3km line spacing is not sufficiently close to detect most fluor clusters. The Great Australian Bight ALF MkII data is probably not suitable for identifying the isolated, low intensity fluors.
