Department of Primary Industry and Fisheries 286 figures below indicate the variation of temperature and salinity over 12 months of sampling. Although not indicated on these figures, results recorded for the Coast and Cleans monitoring project highlight the variation of salinity between the surface and bottom levels of the marina reflecting the impact of fresh water runoff received over the Wet season. Fresh water being lighter and less dense than sea water sits over the heavier more dense sea water. Such environmental conditions provide a hostile environment for native species but can provide invasive opportunities for more tolerant exotic species. Figure 1. Mean monthly surface temperature (oC) levels for the four marinas from February 2000 to February 2001 Figure 2.
