The chemical composition and bacteria communities in acid and metalliferous drainage from the wet-dry tropics are dependent on season.
Acid and metalliferous drainage (AMD) occurs when sulphidic minerals, such as arsenopyrite, chalcopyrite and pyrite, are exposed to oxygen and water. Climate, geology and mine site practices can have a significant impact on AMD composition. The elemental composition of the AMD can also affect the bacterial community. Our hypothesis was that in the dry season the AMD at two mine sites, Rum Jungl...

Remote Mine Site Rehabilitation Monitoring Using Airborne Hyperspectral Imaging and Landscape Function Analysis (lfa)
Landscape Function Analysis (LFA) is an environmental monitoring technique which is internationally recognized as a method of measuring and monitoring ecosystem function and rehabilitation progress. Airborne hyperspectral data were used to generate maps of the three Landscape Function Analysis (LFA) Indices over a 5 x 20 km area of a rehabilitated bauxite mine in southwestern Australia. The tec...
