dc.description.abstractUsing isotopic, geochemical and microfossil analyses of sediment cores, it is possible to reconstruct pre and post-colonial environmental conditions of coastal lakes and estuaries and their catchments. This is an important management tool, not only for determining the baseline 'natural' conditions of these ecosystems but also identifying the nature and extent of changes they have experienced through time, including the influx of pollutants and cha nges in sedimentation regimes. Such information is generally not available from historic records. Practical examples includes the following case-studies: 1) Tasmania & South Australia - Over the past couple of decades “alien species” have been introduced to the coastal waters of Australia and of Tasmania in particular, such as the toxic dinoflagellate Gymnodinium Catenatum. Careful dating and reconstruction of sediment archives have revealed the time and nature of this arrival. 2) NSW Blue Green Algae in the Great Lakes Area: The occurrence of blue- green algal blooms in the Great Lakes area of NSW have now been linked with catchment changes and the dynamics of this coastal system, using reconstructed histories from sediment cores. These detailed histories span the last 60 – 80 years, and cover the post World War II coastal population & development expansion.en_AU
