Use of the diatoms in the environment reconstructions in a deep oligotrophic reservoir during the last 4000 years
The results of the diatom study in a bottom sediment core of 1940 mm length from the underwater Sofia Lepneva Ridge in Lake Teletskoye (Altai, Russia) were presented. The pH value reconstructed by the diatom analysis data for the last 4000 years varied from 7,48 to 7,98 with an average of 7,61±0,004 and corresponded to a weakly alkaline environment.
