Abstract

The Macquarie Harbour water column is highly stratified due to the significant freshwater inputs from the Gordon and King Rivers, deep central basin (maximum depth ~ 50m) and shallow sill at its mouth (<5 m) that restricts exchanges with the ocean. This isolation of deep waters in the Harbour has resulted in a naturally low dissolved oxygen (DO) environment (Creswell et al., 1989; Koehnken 1996). The dark tannin rich freshwater layer limits light penetration and as a consequence productivity is low; the sediments are naturally depauperate of fauna (O’Connor et al. 1996; Talman et al. 1996; Edgar et al. 1999)
