Physical and chemical properties at Turner Point, Lake King North, Gippsland Lakes, Victoria, for 2006–’07. The red line shows surface salinity (ppt) declining rapidly and markedly from late June through early July 2007 (arrow, upper graph) with formation of a halocline as the bottom salinity is only slightly decreased (lower graph). Surface temperature (C, light blue line), dissolved oxygen (% saturation, dark blue line), chlorophyll a (µg/L, green line) and pH (black line) are also depicted.
