Chemical composition of some inland surface waters in South, Western and northeren Australia

Abstract

Numerous analyses of the major ions in surface waters of South Australia, south-western Western Australia, and northern Australia are presented and discussed. In South Australia three regions were investigated: the Yorke Peninsula, the Snowtown area, and the extreme south-east including the Coorong. In all three areas salinities were high, except for Lake Alexandrina and Lake Albert at the mouth of the River Murray, and sodium and chloride were the dominant ions. In rivers and standing waters in the south-west of Western Australia sodium and chloride were likewise the dominant ions. Almost all standing waters sampled in this region were saline and salinity was also high in some rivers investigated; there are, nevertheless, freshwater lakes and rivers of low salinity in this region. In running and standing waters of northern Australia, salinities were low and there was no consistent pattern of ionic dominance.

Notes on the ecology and distribution of non-marine ostracods in Australia

“…Morton & Bayly (1977), in their study of the ecology of some temporary freshwater pools in Victoria, discussed the presence of ostracods in such habitats and described the seasonality of some of the ostracod species. The taxonomic descriptions of freshwater ostracods from north-western Australia by McKenzie (1966a), supplemented by the physicochemical data of Williams & Buckney (1976) and additional remarks of Williams (1979), for the same localities from which the ostracods had been originally collected, are of interest. Similarly, the descriptions of ostracods from mainly athalassic saline waters from Western Australia and South Australia by McKenzie (1978), supplemented by the same work of Williams & Buckney (1976) for the ostracod localities, are informative on salinity tolerance of some species.…”

In addition, Buckney & Tyler (1976) provided chemical data for two saline localities in central Tasmania from which two species of ostracods were collected.…”

The range of salinities in which ostracods are found in Australian waters is summarized in Fig.…”

The aquatic macrophyte flora of saline wetlands in Western Australia in relation to salinity and permanence

“…The ionic composition of saline lakes in Western Australia reported by Williams & Buckney (1976) and Geddes et a1 (1981) shows the constancy so characteristic of Australian saline lakes and similar to that of sea water. As there is no reason to believe the lakes tested in this study differ, ionic composition is not reported.…”

Chinese and Mongolian saline lakes: a limnological overview

“…Even so, a large number of departures from this pattern occurs, with Mg, Ca, SO, and HCO, + CO, sometimes important in particular lakes. Thus, Chinese and Mongolian salt lakes do not have the ionic homogeneity seen, for example, in Australian salt lakes (Williams & Buckney, 1976); in China, at least, whilst the most frequent pattern of ionic dominance is Na>Mg>K>Ca:Cl>SO,>HCO,+CO,, Mg may dominate the cations in some lakes, and HCO, + CO, the anions in others. Table 7 has been compiled in order to illustrate this ionic variety.…”
