Abstract

The upper Swan River estuary located in the eastern suburban area of Perth in Western Australia experiences periods of poor water quality in the form high nutrient levels, anoxic bottom water conditions and occasional nuisance algae blooms. It has long been suspected that oxygen uptake and nutrient release from estuarine sediments are major drivers for these poor water quality conditions. Geoscience Australia in conjunction with the Department of Water in Western Australia investigated water quality in the upper Swan River estuary through water and sediment quality studies in October 2006, September 2007 and May 2008. The objectives of these studies were (1) to characterise the distribution of sediments, in particular to identify areas of high nutrient release, (2) to better understand conditions leading to high oxygen consumption and nutrient release, and (3) to determine the influence of the bottom water oxygen status on nutrient release from sediments.
