| Abstract | Deep Lake is one of a number of hypersaline lakes in the Vestfold Hills near Davis Station in the Australian Antarctic Territory. The lake water which originated as sea water when the lake basin was isolated from the sea following isostatic uplift of this part of the Antarctic Continent, now has a salinity ten times that of sea water The long term trend of decreasing water level has been reversed over at least the past 26 years, the only period for which observations are available. The bulk aerodynamic method using recently revised corrections for salinity has been found to be the most appropriate method for estimating lake evaporation. The terms of the water balance are assessed in the light of longer term climatic conditions and it is concluded that the rising water level in the lake is most likely to be the result of increased blizzard activity in winter transporting snow into the lake. There is some suggestion that the climatic changes may be associated with global warming. |
