Abstract
Microbiological studies of the Central Antarctica glacier have reveale d a diverse microflora in all layers: from the surface to the ancient located at a depth of-about 3000 m and approximately 250000 years old. The total number of microbial cells in all studied horizons of the gl acier varied within the limits of 10(2)-10(3) cells per cm(3) of ice. The abundance of microorganisms in different horizons of the glacier v aried by an order of magnitude. Comparison of these data with the resu lts of glaciological studies has shown a direct relationship between t he number of microbial cells in the studied glacier layers and climati c changes on the Earth during different periods of its geological hist ory.
