Abstract
Concentrations of carotenoids buried in the bottom sediments of Lake Shira (Siberia, Khakasiya) were analyzed over the time interval of the last 2300 years. Carotenoids that are molecular markers of the corresponding groups of phototrophic organisms were detected in the bottom sediments. It was shown that the bottom sediments of Lake Shira are a promising object for climatic reconstructions of late Holocene in Southern Siberia.
