Abstract
The Arafura Sea airborne laser fluorosensor (ALF) MkII survey was flown in 1989 by BP. The survey was designed to detect natural oil seepage over a region of the Arafura Sea, Northern Australia, in an effort to refine the petroleum prospectivity assessment. An area of about 400km by ~150km was surveyed at 5km line spacing. A total of 534,022 fluorosensor spectra were recorded. This report is a re-interpretation of the BP data by Signalworks Pty Ltd using the ALF Explorer? software. A total of 1894 fluors were picked out of the 534,022 recorded spectra in the final interpretation. This is an average fluor density of 3.55 fluors per thousand spectra. The fluorescence response over most of the survey area consisted mainly of relatively low confidence fluors (compared to the more reliable MkIII survey data). While fluor density variations can be seen on the fluor map the geological implications are not clear. Because of its susceptibility to noise, the MkII ALF system produces less confident fluor maps than the MkIII system. Some mapped fluor density variations may be influenced by sea state or water property variations.
