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.
Ice-cored moraines are the only accumulation forms of Antarctic ice-sheet in the contact zone with Bunger Hills. Their longiness ranges from 3.5 km to 250 m, they are from 300 m to 30 m wide and their elevation oscillates between 10 and 5 m. A thickness of moraimc cover which lags the ice-core is changeable in the limit of 1 m. A process of decay of ice-cores, leading to deformations of their moraines, plays a small part up to now. It is caused a dry climate, probably, which was not favorable for the release and the work of melted waters in a large scale. The weak separation of ice-cored moraines results from a small amount of morainic material transported to the front of ice-sheet, probably as the ice-sheet is almost motionless. The granulometric analysis of morainic sediments shows their bad segregation.
