Abstract

The Browse Basin airborne laser fluorosensor (ALF) MkII survey was flown in 1989. The MkII system used a 308nm laser wavelength, which is longer than the 266nm used in the later MkIII system. The Raman peak wavelength is 344nm (293nm MkIII) and the fluorescence region is 370nm to 580nm (320nm to 580nm MkIII). 32 lines were acquired at about 5,000m spacing in a NNE-SSW orientation and a flying height of 100m. A total of 133,125 spectra were collected at an average spacing of 16m to 25m. About 2,270 km of line data were acquired. Each recorded spectrum is the average (or sum) of ten detected spectra. The averaging was done to reduce the data recording rate, which was limited by the available hardware. The survey was interpreted using the ALF Explorer application that consists of a database linked to a set of data processing, analysis and display modules. A total of 776 fluors were interpreted out of the 133,125 recorded spectra. The fluorescence response over most of the survey area consisted mostly of relatively low confidence fluors. High intensity fluors are located over Scott Reef but are probably caused by the reef material fluorescing.
