Under the ice in Antarctica.


 The 1985 Antarctic Scientific Research Expedition to Lake Hoare in Taylor Valley is briefly described. Of particular interest to to the expedition is the nature of the lake's perennial ice cover and its role in concentrating dissolved gases. Also, the algal mats and sediment found on the bottom of the lake were studied. Antarctic lakes have been cited as possible analogs for possible biological habitats on Mars and on Europa.
