The results of chemical and biological analyses of lake water samples, taken in the Bunger Hills during January—March 1987 by the participants of the 32-nd Soviet Antarctic Expedition from the new seasonal station „Oasis-2" (66°16'S and 110°45'E) are presented. It was discovered that the sea contributed considerably to the formation of intraoasis isolated reservoirs. The water of the epishelf lake — Transkripcii Bay — consists of two layers: upper freshwater (0,3—l,0‰) and lower salt water (19‰); the bottom water contains H2S. The phosphate concentration varied from 3—8 mg 1-1 in freshwater lakes to 37 mg 1-1 in Rybij Chvost Bay (Pass Cove), where the high concentration of chlorophyll „a" (up to 10 mg 1-1) was found.
