Abstract: Features of the hydrological (temperature, conductivity, solar radiation) and biological (phytoplankton, zooplankton and bottom communities) regimes of 27 diverse lakes in the oases of Eastern Antarctica: The Thala Hills, Schirmacher and Larsemann Hills in the summer period 2010–2011 are investigated. The main aim was to compare the dynamics of hydrological regime and biological components of lakes related to changes in environmental conditions and comparing the data with the results obtained by other authors. Appearance of ice-free period in the deep lakes of East Antarctica is accompanied by a decrease in biological activity of organisms. Effect of warming is marked in some lakes of Schirmacher Oasis.
