Chemical and biological observations on some volcanic lakes in the south-east of South Australia

Abstract

Chemical and biological data are given relating to the four lakes near Mount Gambier, South Australia, and to Lake Leake about 32 km to the north-west. The chemical data reveal that despite some similarities there are clear differences in ionic composition between the lakes. These differences are explained as being due to the differing importance of terrestrial and atmospheric ion supply. The biological data are discussed principally from a distributional viewpoint.
