Abstract
Previous work has shown that accumulations of macroalgae have been associated with the loss of seagrasses in Oyster Harbour, near Albany in Western Australia (Bastyan, 1986; Kirkman, 1987). This observation prompted further studies into the water quality, seagrasses and macroalgae of the harbour, including an intensive sampling program in February 1988 to determine the size of the nutrient pools in water, sediments and plants (Hillman et al, 1990).
The year preceding the 1988 sampling program had the lowest rainfall in sixteen years, and this would have resulted in low runoff and low stream nutrient loading. However, the next winter (1988) was the wettest in ten years, with consequent increased river flow. It was suggested that macroalgal biomass might have increased in summer 1988/1989, in response to a presumably increased nutrient load. A survey was therefore carried out in March 1989 to check this hypothesis, using the same techniques as those employed in the previous summer.
