Phytoplankton in the cooling pond of a nuclear fuel plant. Spectral Analysis (Report 1)
- Institute of Biophysics, Moscow (Russian Federation)
Dynamics of average monthly indices for 3 classes of phytoplankton and for 24 hydrochemical 7 meteorological, and 3 radiative factors were investigated over a period of 26 years in the cooling pond of the Mayak Production Association in Kyzyl-Tash Lake. The parameters were statistically treated by procedures of time series analysis. A seasonal succession of examined features is described. It is established that development of the diatoms peaks in February, and that of the green and the blue-green algae peaks in June and August, respectively. Seasonal growth of the blue-green algae is substantially influence by water temperature, Mn{sup 2+}, O{sub 2}, CO{sub 2}, and solar radiation; that of the green algae is effected by water temperature, solar radiation, CO{sup 2}, Mn{sup 2+}, and cloudiness; that of the diatoms is controlled by SiO{sub 3}{sup 2-}, K{sup +} + Na{sup +}, CO{sub 2}, and water temperature. 6 refs., 2 figs., 1 tab.
