Cowley, R., 2001. Mk II Airborne Laser Fluorosensor Survey Reprocessing and Interpretation Report: Timor Gap, Timor Sea, Australia. Record  2001/025. AGSO-Geoscience Australia, Canberra.

Abstract

The Timor Gap airborne laser fluorosensor (ALF) MkII survey was flown in 1989 by BP over the northern Bonaparte Basin (Sahul Platform, Sahul Syncline and Malita Graben). 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). 208 lines were acquired at about 1,900m spacing in a NW-SE orientation and a flying height of 100m. A total of 1,860,650 spectra were collected at an average spacing of 16.9m to 28.5m. About 36,000 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 software that consists of a database linked to a set of data processing, analysis and display modules. A total of 392 fluors were interpreted out of the 439,972 recorded spectra. 68 of these are located in a single patch near the Jabiru Field. This patch contains many very large fluors.
