Title: Lake Bonney, Antarctica: Cause of the elevated temperatures
Abstract: The temperature of the water in ice-covered Lake Bonney is a maximum of 7.5°C at 13-m depth and a minimum of −2.5°C at the bottom, a depth of 32 m. The concentration of dissolved salt increases with depth throughout, the maximum rate of increase occurring at 14-m depth. These data are consistent with the hypothesis that 60 years ago a layer of fresh water, 10 m deep, flowed onto the surface of a salty, convecting lake at −20°C; that the annual solar radiation penetrating the ice cover is 1400 cal cm−2; and that the geothermal flux is 4 times normal. Records of explorations in the area show that such an increase in depth did occur between 1903 and 1911.
