Aspects of the Limnology of Yeppen Yeppen Lagoon, Central Queensland

摘要: Aspects of the morphometry and physical chemical limnology Yeppen Lagoon, in tropical Australia, have been investigated. The lagoon is a channel billabong lying old bed Fitzroy River. It has relatively small, shallow elongated basin. Seasonal variations water temperature, light regime, oxygen concentration, pH conductivity suggest that exhibits warm monomictic pattern thermal stratification rather than continuous polymictic one. annual heat budget was 3294 calories cm-2 year-1. Maximum work wind 238.8 g-cm cm-2, maximum stability 34.5 cm-2. Despite apparently low stratification, remained thermally stratified for much year. Analysis wind-distributed suggested slow mixing taking place even during periods high stability, although this insufficient to reoxygenate hypolimnion, which anoxic Lagoon likely prove eutrophic, it primary productivity will be because large volume lagoon's well lit sediment surface area contact with epilimnion. Notes on biota are also given.
